Infusion of allogeneic BK virus-specific T cells may be an effective treatment for patients with progressive multifocal leukoencephalopathy (PML), according to a report in the October 11 New England Journal of Medicine. The infusion cleared JC virus from the CSF of two patients and reduced viral load in the third, reported lead author Muharrem Muftuoglu, MD, of the Department of Stem Cell Transplantation and Cellular Therapy at the University of Texas MD Anderson Cancer Center in Houston, and colleagues. One of the patients completely recovered and returned to work; this outcome was unprecedented in PML therapy.

“Several approaches for the treatment of PML, including the use of antiviral medications and mirtazapine, have been tested, with poor results,” the investigators said. Although virus-specific T-cell infusion is a novel approach to treating PML, this method has been used for other conditions. “Several groups, including ours, have successfully used viral-specific T cells to treat BK virus infection after stem-cell transplantation,” the investigators said. “Because BK virus and JC virus are genetically similar to one another and share a number of immunogenic proteins with a substantial degree of sequence homology ... we hypothesized that T cells developed against BK virus may also be effective against JC virus infection.”

This hypothesis proved correct. The investigators infused three patients with PML with “cryopreserved, third-party–produced, viral-specific T cells that had been designed for the treatment of patients with BK virus infection after stem-cell transplantation.” Each patient presented with a different condition and PML-precipitating therapy. The first patient was a 32-year-old woman with high-risk acute myeloid leukemia who had received a cord-blood transplantation, the second a 73-year-old woman with JAK2-positive myeloproliferative neoplasia on ruxolitinib therapy, and the third a 35-year-old man with HIV who had received highly active antiretroviral therapy.

T-cell infusions cleared JC virus from the CSF of the woman with leukemia (three infusions) and the man with HIV (four infusions). These patients recovered to different degrees.The woman had full resolution of symptoms, while the man had slurred speech and walked with a cane. Treatment reduced JC viral load in the elderly woman with myeloproliferative neoplasia (two infusions), but she did not clear the virus and died about eight months later.

No adverse events occurred, but two patients developed immune reconstitution inflammatory syndrome. This outcome was likely caused by the T-cell infusion, since absolute T-cell counts remained steady and white matter enhancement was detected on MRI within four weeks of treatment. Still, the investigators were optimistic about future potential.

“Third-party–produced, ‘off-the-shelf,’ partially HLA-matched, BK virus–specific T cells may serve as therapy for PML,” the investigators concluded. “Further study in a larger group of patients is required to determine the success rate, durability, and longer-term adverse events associated with this treatment.”

The study was funded by the MD Anderson Cancer Center Moon Shots Program and the National Institutes of Health.

Myth: Psoriasis Is Only a Skin Problem

Psoriasis is predominantly regarded as a skin disease because of the outward clinical presentation of the condition. However, psoriasis is a disorder of the immune system and its damage may be more than skin deep.

Psoriasis commonly presents on the skin and nails, but a growing body of evidence has suggested that psoriasis is associated with systemic comorbidities. Up to 25% of psoriasis patients develop joint inflammation, and psoriatic arthritis (PsA) may precede skin involvement. There also is a risk for cardiovascular complications. Because of the emotional distress caused by psoriasis, patients may develop psychosocial disorders. Other conditions in patients with psoriasis include diabetes mellitus, high blood pressure, Crohn disease, and the metabolic syndrome.

Results from surveys conducted by the National Psoriasis Foundation from 2003 to 2011 found that the diagnosis of psoriasis preceded PsA in the majority of patients by a mean period of 14.6 years. Patients with moderate to severe psoriasis were more likely to develop PsA than patients with mild psoriasis. Furthermore, patients with severe psoriasis were more likely to develop diabetes mellitus and cardiovascular disease.

In a Cutis editorial, Dr. Jeffrey Weinberg emphasizes that the role of the dermatologist “is to identify and educate patients with psoriasis who are at risk of systemic complications and ensure appropriate follow-up for their treatment and overall health.” An infographic created by the American Academy of Dermatology illustrates areas of the body that may be impacted by psoriasis beyond the skin; for example, patients may develop eye problems, weight gain, or mood changes. Consider distributing this infographic to patients to show how psoriasis can affect more than their skin.

SAN ANTONIO – For treatment of the axilla in women with early-stage breast cancer having a positive sentinel node, the risk-benefit calculus tilts toward radiation therapy over axillary lymph node dissection, finds an update of the phase 3, noninferiority, randomized AMAROS trial.

Susan London/MDedge News

The trial’s previously reported 5-year results showed noninferiority of axillary radiation relative to axillary lymph node dissection (ALND) with respect to axillary recurrences, as well as less lymphedema (Lancet Oncol. 2014 Nov;15(12):1303-10). But the trial was criticized as being underpowered and having insufficient follow-up, according to principal investigator Emiel J. T. Rutgers, MD, PhD, of the Netherlands Cancer Institute in Amsterdam.

Now, at a median follow-up of 10 years, findings were basically the same, with few additional axillary recurrences having occurred in either group, he reported in a session and press conference at the San Antonio Breast Cancer Symposium. There was a nonsignificant difference in the very-low 10-year cumulative incidences of axillary recurrence, and no significant difference in other efficacy outcomes. Meanwhile, an update of the rate of lymphedema at 5 years continued to show that this treatment complication was about half as common with radiation.

The radiation therapy group did have a higher risk of second primaries, with an absolute difference of about 4%, mainly driven by more contralateral breast cancers. But it was unclear whether this difference was related to the radiation, according to Dr. Rutgers.

“Both axillary clearance and radiotherapy provide excellent, comparable locoregional control in patients who have a positive sentinel node in the axilla,” he summarized. “After 10 years [of follow-up], there is significantly less lymphedema after radiation therapy at 5 years, and therefore this can be considered a standard procedure.”

Putting data into practice

SABCS codirector and press conference moderator Virginia Kaklamani, MD, leader of the breast cancer program at University of Texas, San Antonio, wondered how Dr. Rutger’s institution has incorporated findings of the AMAROS trial and findings of the previously reported ACOSOG Z11 trial (JAMA. 2011;305:569-75).

They apply both, on a case-by-case basis, he replied. “If it’s limited node involvement in early breast cancer – and of course that’s subjective, we have some cutoffs for that – we do nothing if the sentinel node is positive. If it’s a larger tumor, high grade, lymphovascular invasion, and there are two positive sentinel nodes, then we irradiate the axilla according to the AMAROS trial. This is a discussion within our tumor board, of course, with the multidisciplinary team and together with the patient.”


Over the past 20 years, the percentage of women at his institute undergoing axillary clearance has fallen sharply, from about 75% to merely 3%, as a result of introduction of and growing evidence on sentinel node biopsy, advances in radiation therapy, and increased use of neoadjuvant chemotherapy, according to Dr. Rutgers. “At our institute, an axillary clearance in breast cancer is a rare operation for our residents. They have to go to the melanoma doctors to learn axillary clearance.” At the same time, the occurrence of lymph node metastases has remained unchanged at about 1% annually.

“This is really the beauty of this sort of deescalation in therapy, where you’re improving the morbidity of our patients – our patients have a better quality of life because they don’t have as much lymphedema – without compromising their outcomes. The chance of them having a local recurrence is very low,” Dr. Kaklamani commented. “So taking 20 and 30 and sometimes 40 lymph nodes out, like we used to do, isn’t needed anymore.”

Still, selecting the right patient for radiation is important, she cautioned, as the findings do not apply to those with a bulky lymph node, for example. “But the majority of patients we see with breast cancer have these small metastases to their axillas, if they do [have any], and in those cases, doing radiation, instead of doing more surgery or not doing anything, is very appropriate.”

Changing the standard in the United States has historically been slow. “It is the longer follow-ups from Z11, from AMAROS that are helping our surgeons cut back on the amount of surgery that they are doing,” Dr. Kaklamani maintained. “I have been surprised because we have had these trials out for 10 years, and we still are doing more axillary node dissections than we should be doing.”

At the global level, trends in use of ALND by country and region have varied depending on national practice patterns and acceptance of the trial data, according to Dr. Rutgers. “Taking a toy away from a surgeon is a difficult thing to do.”

Study details

The AMAROS trial was conducted by the European Organization for Research and Treatment of Cancer Breast Cancer Group and Radiation Oncology Group, in collaboration with the Dutch Breast Cancer Research Group and the ALMANAC Trialists’ Group.

The 1,425 patients randomized had breast cancer that was clinically node negative by either palpation or ultrasound (cT1-2,N0) and were scheduled for breast-conserving surgery or mastectomy.

The updated results showed that the 10-year cumulative incidence of axillary recurrence was 1.82% with axillary radiation and 0.93% with ALND, a nonsignificant difference (hazard ratio, 1.71; P = .365), Dr. Rutgers reported. The women also had statistically indistinguishable rates of disease-free survival (HR, 1.19; P = .105), as well as distant metastasis–free survival and overall survival.

The 10-year cumulative incidence of second primaries was higher with radiation than with ALND: 12.09% versus 8.33% (HR, 1.45; P = .035). “This is to some extent due to contralateral breast cancers,” Dr. Rutgers commented. “We cannot exclude an effect of the radiotherapy to the axilla, but we have to realize that 85% of these patients received radiotherapy anyway because of breast conservation. So for us, it is difficult to see whether the addition of the axillary radiation field would lead to more second primaries.”

The updated 5-year rate of lymphedema (data for this outcome were not collected at 10 years) showed persistence of a large difference in the occurrence of lymphedema as defined by clinical observation and/or treatment: 29.4% with ALND and 14.6% with radiation (P less than .0001).

Dr. Rutgers reported that he had no relevant conflicts of interest. The study was supported by the EORTC Charitable Trust.

SAN ANTONIO – Phase 2 neoadjuvant endocrine therapy breast cancer trials can and should serve as a testing platform to inform the design of phase 3 trials with the ability to change practice, according to Ingrid A. Mayer, MD.

Correlating outcomes such as the Preoperative Endocrine Prognostic Index and Ki67 blood levels from phase 2 trials to larger, similarly designed trials could reduce costs, time, and the need for large numbers of patients, thereby promoting more efficient development of effective breast cancer therapies, she said during a plenary lecture at the San Antonio Breast Cancer Symposium.

In this video interview, Dr. Mayer, director of breast medical oncology at Vanderbilt University, Nashville, Tenn., explained that while neoadjuvant endocrine therapy is suitable for down-staging tumors in women with stage I-III breast cancer, it is not commonly used, as those patients are also good surgery candidates.

However, neoadjuvant endocrine therapy can be “an incredible platform” to test novel combinations of endocrine therapy agents with or without targeted treatments, validate new biomarkers, discover mechanisms of resistance, and predict the best combinations for moving forward in phase 3 trials, she said, adding that “this is something that all academic institutions potentially should be doing.”

Although the direct clinical benefit for patients who participate in such trials is not tremendous, participation has the potential to ultimately improve outcomes for participants and for “their friends and families and daughters,” and to help propel the science forward, Dr. Meyer noted.

“I would argue that we really should be moving forward to designing trials in the neoadjuvant endocrine setting more and more, and really utilizing this platform for that end,” she said.

SAN ANTONIO – When disseminated tumor cells – even a single cell – are detected in the bone marrow of patients with early breast cancer, it’s not a good sign, according to results of pooled international analysis.

The presence of disseminated tumor cells (DTCs) in marrow at the time of primary diagnosis was an independent prognostic factor for overall survival (OS), disease-free survival (DFS), and distant disease-free survival (DDFS), reported Andreas Daniel Hartkopf, MD, MSc, of the University of Tübingen, Germany, on behalf of colleagues in the PADDY study.

“The DTC detection was associated with higher local tumor burden and more aggressive biological subtype,” he said at the San Antonio Breast Cancer Symposium.

The PADDY (Pooled Analysis of DTC Detection in Early Breast Cancer) study is an international cooperative effort designed to evaluate the association between DTC detection in patients with early breast cancer and clinical outcomes.

The investigators collected individual data sets including information on bone marrow samples from 10,307 patients treated at 11 centers in the United States and Europe.

The patients had early invasive breast cancer (T1-4, NO-3, M0) and for inclusion in the study had to have had bone marrow aspiration performed at the time of diagnosis or during primary surgery, with no prior systemic therapy. DTCs were detected by cytokeratin staining.

Patients were defined as being DTC positive if one or more DTCs were detected.

A total of 2,814 of the 10,307 patients (27.3%) were DTC positive. DTC status was not significantly associated with menopausal status or tumor histology (invasive ductal, invasive lobular, or other), but was positively associated with tumor grade, with 21.1% of patients with grade 1 tumors being DTC positive, compared with 27.2% with grade 2 tumors, and 29.9% with grade 3 tumors (P less than .001).

At a median follow-up of 7.6 years from bone marrow sampling DTC positivity was significantly associated with, in addition to higher tumor grade, higher T stage, nodal positivity, estrogen and progesterone receptor negativity, and HER2 positivity (P less than .001 for all).

Univariate analysis showed that DTC-positive patients had significantly shorter OS, breast cancer–specific survival, and DDFS compared with DTC negative patients (P less than .001 for all).

In a multivariate model stratified by center and controlling for age, menopausal status, histology, tumor size, nodal status, and biological subtype, DTC was an independent prognostic marker for OS (hazard ratio 1.23, P = .006), DFS (HR 1.30, P less than .001) and DDFS (HR 1.30, P = .006), but not for locoregional relapse-free survival.

“These results confirm that DTC detection is an independent risk factor for metastatic relapse and poor overall survival in early breast cancer,” Dr. Hartkopf said.

There was a statistically significant interaction between DTCs and subtypes with regard to DDFS, with a HR of 2.34 for patients with luminal B disease (P = .014).

“Future trials must evaluate the predictive value of DTC detection and/or their characterization on adjuvant therapy efficacy,” Dr. Hartkopf concluded.

Dr. Hartkopf did not disclose a study funding source or potential conflicts of interest.

SAN ANTONIO – A tailored 12-month exercise program during adjuvant breast cancer treatment appears to protect cardiovascular function, particularly in patients receiving chemotherapy, according to findings from the randomized EBBA-II trial.
 

The overall change in VO_2max at 12 months was +0.3% in 271 patients randomized to the intervention group, compared with –8.9% in 274 patients in the “usual care” control group, Inger Thune, MD, PhD, said at the San Antonio Breast Cancer Symposium.

Among patients receiving chemotherapy, the VO_2max change at 12 months was +1.6% in 120 patients in the intervention group, compared with –2.76% in 122 patients in the control group, said Dr. Thune of the Cancer Center at Oslo University Hospital.

Study participants were women aged 18-75 years (mean of 55 years at diagnosis) with stage I-II breast cancer, mean body mass index of 25 kg/m², and a mean VO_2max before surgery of 31.5 mL/kg per minute. The intervention group entered a 12-month individualized exercise program 2-3 weeks after surgery based on their own VO_2max at baseline.


They met for training sessions in groups of 10-12 women for 60 minutes twice weekly over the 12-month study period, and were also told to perform at least 120 minutes of exercise at home for a total of 240 minutes of exercise weekly.

Of note, the adherence rate among participants was encouragingly high at about 90%, she said, adding that the findings strongly support tailored exercise during adjuvant breast cancer treatment, as such an intervention appears to counteract declines in cardiovascular function – particularly in those receiving chemotherapy.

In this video interview, Dr. Thune further discussed the study design, implications of the findings, and future directions.

“Cardiovascular morbidity is so important for our breast cancer patients that I think that it’s time to have physical activity [and] physical function as a main interest for all clinicians dealing with breast cancer patients,” she said.

SAN ANTONIO – Oxybutynin (Ditropan), a drug approved to treat overactive bladder, is highly efficacious and well tolerated when used to alleviate hot flashes, according to results of a randomized, controlled trial of 150 women reported by lead author Roberto A. Leon-Ferre, MD.

The women, about two-thirds of whom were breast cancer survivors taking tamoxifen or aromatase inhibitors, were having at least 28 hot flashes weekly at baseline. Results of the trial showed that the 6-week reduction in a hot flash score capturing both frequency and severity was about 30% with placebo, 65% with oxybutynin 2.5 mg b.i.d., and 80% with oxybutynin 5 mg b.i.d. (P less than .01 across groups).

There also was a significant difference in quality of life in favor of the drug and, in the higher-dose group, significantly better scores for mood and life enjoyment. In a video interview, Dr. Leon-Ferre discussed how oxybutynin compares with other available treatment options, which women are good or poor candidates for this drug, and how the findings have influenced his own practice.

Dr. Leon-Ferre of the Mayo Clinic, Rochester, Minn., disclosed that he had no relevant conflicts of interest. The study was funded by the Breast Cancer Research Foundation.

SAN ANTONIO – Younger breast cancer patients who undergo unilateral or bilateral mastectomy report lower breast satisfaction and poorer psychosocial and sexual well-being than counterparts who undergo breast-conserving surgery, finds a cross-sectional cohort study presented by lead investigator Laura S. Dominici, MD, FACS, at the San Antonio Breast Cancer Symposium.

The 560 women studied had a mean age of 37 years and had completed the BREAST-Q questionnaire a median of 5.8 years after their breast cancer diagnosis. Results showed that the mean score for satisfaction with breasts was 65.5 with breast-conserving surgery, 59.3 with unilateral mastectomy, and 60.4 with bilateral mastectomy (P = .008). The mastectomy groups also had poorer scores for psychosocial well-being (P less than .001) and sexual well-being (P less than .001), but not physical well-being. Most of the differences remained significant in meta-analysis. In a video interview, Dr. Dominici, of Dana-Farber Cancer Institute, Boston, discussed worry and anxiety about recurrence and second cancers as drivers of choosing mastectomy, generalizability of the study’s findings, and strategies for incorporating this new information into counseling and shared decision making.

Dr. Dominici disclosed that she had no conflicts of interest. The study was funded by the Agency for Healthcare Research and Quality, Susan G. Komen, the Breast Cancer Research Foundation, and The Pink Agenda.

SAN ANTONIO – Women with localized breast cancer who achieve a pathological complete response (pCR) after neoadjuvant chemotherapy may be able to safely skip adjuvant chemotherapy, suggest new data from a patient-level meta-analysis reported in a session and press conference at the San Antonio Breast Cancer Symposium.

Susan London/MDedge News

“The focus of many breast cancer trials for several years has been on adding additional systemic therapies to reduce recurrence risk. However, adding therapies can result in additional toxicity and overtreatment for many patients,” noted lead investigator Laura M. Spring, MD, of Massachusetts General Hospital Cancer Center and Harvard Medical School, both in Boston. “The neoadjuvant chemotherapy model offers several additional clinical and research advantages over adjuvant chemotherapy, including the rapid evaluation of treatment response utilizing surrogate biomarkers, such as pathological complete response.”

The meta-analysis of 52 studies, which included a total of 27,895 women who were given neoadjuvant chemotherapy, confirmed a large positive prognostic effect of pCR on outcomes in the entire sample, with a 69% relative reduction in event-free survival (EFS) events and a 78% relative reduction in risk of death, a pattern that was consistent across clinical subtypes of breast cancer. More importantly, among those achieving a pCR, EFS did not differ significantly whether they went on to receive more chemotherapy after surgery or not.

“Achieving pCR following neoadjuvant chemotherapy is associated with significantly improved EFS and overall survival, particularly for triple-negative and HER2-positive breast cancer. The results are highly significant despite inclusion of a variety of neoadjuvant regimens, suggesting the path taken to attain a pCR may not be critical,” Dr. Spring proposed. “The similar outcomes with or without adjuvant chemotherapy in patients who attained pCR after neoadjuvant chemotherapy likely reflects tumor biology and suggests adjuvant chemotherapy could potentially be omitted in certain circumstances. Further research is needed to evaluate the clinical utility of escalation and de-escalation strategies in the adjuvant setting based on neoadjuvant response.”

“Basically, it appears that the impact of chemotherapy is going to be early, or if you use it early, you really don’t lose the impact [that it has] if you wait until after surgery,” commented SABCS codirector and press conference moderator Carlos Arteaga, MD, director of the Harold C. Simmons Comprehensive Cancer Center and associate dean of Oncology Programs at UT Southwestern Medical Center, Dallas, Texas. “So if it was me, I would have it done before the operation, frankly, because at a minimum, it’s not worse than delaying it until after surgery – at a minimum. And you get the benefit of potential breast conservation, a lesser surgery.”

For the meta-analysis, Dr. Spring and her coinvestigators searched for published studies of localized breast cancer that had 25 patients or more, featured neoadjuvant chemotherapy, and reported pCR using definitions allowed by the FDA (ypT0 ypN0 or ypT0/is ypN0), as well as recurrence and/or survival based on pathologic outcome. They excluded studies reporting only local recurrence and those using neoadjuvant endocrine therapy or neoadjuvant radiation.

Results showed that the pCR rate averaged 21.1% for the entire study population, according to Dr. Spring. But there was wide variation by tumor subtype, as expected, with a rate of less than 10% for hormone receptor–positive/HER2-negative breast cancer, to rates in the mid-30% range for triple-negative breast cancer and HER2-positive breast cancer.

Women who had pCR after neoadjuvant chemotherapy had a significantly lower risk of EFS events than peers who had residual disease (hazard ratio, 0.31; 95% probability interval, 0.24-0.39). The corresponding 5-year EFS rates were 88% and 67%.

Similarly, women who had pCR had a significantly lower risk of death (HR, 0.22; 95% probability interval, 0.15-0.30). The corresponding 5-year overall survival rates were 94% and 75%.

The EFS benefit of pCR versus residual disease was consistently seen across subgroups with triple-negative breast cancer (90% vs. 57%), HER2-positive breast cancer (86% vs. 63%), and hormone receptor–positive/HER2-negative breast cancer (97% vs. 88%). Findings were essentially the same for overall survival, according to Dr. Spring.

Among patients attaining pCR, the 5-year EFS rate was 86% for those who went on to receive adjuvant chemotherapy (HR, 0.36; 95% probability interval, 0.19-0.67) and 88% for those who did not (HR, 0.36; 95% probability interval, 0.27-0.54). The difference in hazard ratios between groups was not significant (P = .60).

Finally, the investigators conducted modeling to assess how the change in pCR rate corresponded with the change in EFS benefit. “This approach could be helpful in the design of neoadjuvant studies,” Dr. Spring explained.

“Assuming pCR is a valid surrogate endpoint, this is, it mediates all treatment effects, and that the average pCR is 50%, the magnitude of pCR change is predictive of treatment effects on EFS within a certain amount of uncertainty, based on the model,” she reported. For example, a change in pCR of 0.3 had a corresponding HR of 0.72, with a 95% probability interval of 0.68-0.77.

SAN ANTONIO – Women with localized breast cancer who achieve a pathological complete response (pCR) after neoadjuvant chemotherapy may be able to safely skip adjuvant chemotherapy, suggest new data from a patient-level meta-analysis reported in a session and press conference at the San Antonio Breast Cancer Symposium.

“The focus of many breast cancer trials for several years has been on adding additional systemic therapies to reduce recurrence risk. However, adding therapies can result in additional toxicity and overtreatment for many patients,” noted lead investigator Laura M. Spring, MD, of Massachusetts General Hospital Cancer Center and Harvard Medical School, both in Boston. “The neoadjuvant chemotherapy model offers several additional clinical and research advantages over adjuvant chemotherapy, including the rapid evaluation of treatment response utilizing surrogate biomarkers, such as pathological complete response.”

The meta-analysis of 52 studies, which included a total of 27,895 women who were given neoadjuvant chemotherapy, confirmed a large positive prognostic effect of pCR on outcomes in the entire sample, with a 69% relative reduction in event-free survival (EFS) events and a 78% relative reduction in risk of death, a pattern that was consistent across clinical subtypes of breast cancer. More importantly, among those achieving a pCR, EFS did not differ significantly whether they went on to receive more chemotherapy after surgery or not.

“Achieving pCR following neoadjuvant chemotherapy is associated with significantly improved EFS and overall survival, particularly for triple-negative and HER2-positive breast cancer. The results are highly significant despite inclusion of a variety of neoadjuvant regimens, suggesting the path taken to attain a pCR may not be critical,” Dr. Spring proposed. “The similar outcomes with or without adjuvant chemotherapy in patients who attained pCR after neoadjuvant chemotherapy likely reflects tumor biology and suggests adjuvant chemotherapy could potentially be omitted in certain circumstances. Further research is needed to evaluate the clinical utility of escalation and de-escalation strategies in the adjuvant setting based on neoadjuvant response.”

“Basically, it appears that the impact of chemotherapy is going to be early, or if you use it early, you really don’t lose the impact [that it has] if you wait until after surgery,” commented SABCS codirector and press conference moderator Carlos Arteaga, MD, director of the Harold C. Simmons Comprehensive Cancer Center and associate dean of Oncology Programs at UT Southwestern Medical Center, Dallas, Texas. “So if it was me, I would have it done before the operation, frankly, because at a minimum, it’s not worse than delaying it until after surgery – at a minimum. And you get the benefit of potential breast conservation, a lesser surgery.”

For the meta-analysis, Dr. Spring and her coinvestigators searched for published studies of localized breast cancer that had 25 patients or more, featured neoadjuvant chemotherapy, and reported pCR using definitions allowed by the FDA (ypT0 ypN0 or ypT0/is ypN0), as well as recurrence and/or survival based on pathologic outcome. They excluded studies reporting only local recurrence and those using neoadjuvant endocrine therapy or neoadjuvant radiation.

Results showed that the pCR rate averaged 21.1% for the entire study population, according to Dr. Spring. But there was wide variation by tumor subtype, as expected, with a rate of less than 10% for hormone receptor–positive/HER2-negative breast cancer, to rates in the mid-30% range for triple-negative breast cancer and HER2-positive breast cancer.

Women who had pCR after neoadjuvant chemotherapy had a significantly lower risk of EFS events than peers who had residual disease (hazard ratio, 0.31; 95% probability interval, 0.24-0.39). The corresponding 5-year EFS rates were 88% and 67%.

Similarly, women who had pCR had a significantly lower risk of death (HR, 0.22; 95% probability interval, 0.15-0.30). The corresponding 5-year overall survival rates were 94% and 75%.

The EFS benefit of pCR versus residual disease was consistently seen across subgroups with triple-negative breast cancer (90% vs. 57%), HER2-positive breast cancer (86% vs. 63%), and hormone receptor–positive/HER2-negative breast cancer (97% vs. 88%). Findings were essentially the same for overall survival, according to Dr. Spring.

Among patients attaining pCR, the 5-year EFS rate was 86% for those who went on to receive adjuvant chemotherapy (HR, 0.36; 95% probability interval, 0.19-0.67) and 88% for those who did not (HR, 0.36; 95% probability interval, 0.27-0.54). The difference in hazard ratios between groups was not significant (P = .60).

Finally, the investigators conducted modeling to assess how the change in pCR rate corresponded with the change in EFS benefit. “This approach could be helpful in the design of neoadjuvant studies,” Dr. Spring explained.

“Assuming pCR is a valid surrogate endpoint, this is, it mediates all treatment effects, and that the average pCR is 50%, the magnitude of pCR change is predictive of treatment effects on EFS within a certain amount of uncertainty, based on the model,” she reported. For example, a change in pCR of 0.3 had a corresponding HR of 0.72, with a 95% probability interval of 0.68-0.77.

BERLIN – In the changing multiple sclerosis landscape, more women are having babies, and more are asking questions. With these women, what’s the best way to address the complicated interplay among pregnancy, relapse risk, breastfeeding, and medication resumption? A starting point is to recognize that “women with MS are very different today than they were 25 years ago,” said Annette Langer-Gould, MD, PhD. Not only have diagnostic criteria changed but also highly effective treatments now exist that were not available when the first pregnancy cohorts were studied, she pointed out, speaking at the annual congress of the European Committee on Treatment and Research in Multiple Sclerosis.

The existing literature, said Dr. Langer-Gould, has addressed one controversy: “Most women with MS can have normal pregnancies – and breastfeed – without incurring harm,” though it’s true that severe rebound relapses are possible if natalizumab (Tysabri) or fingolimod (Gilenya) are stopped before pregnancy. In any case, new small-molecule MS medications need to be stopped during pregnancy and breastfeeding, she pointed out. “We didn’t have to worry about that too much when we only had injectables and monoclonal antibodies because they were larger and didn’t cross the placenta.”

Since the 1980s, the conversation about pregnancy and MS has moved from asking “Is pregnancy bad for women with MS?” to the current MS landscape, in which sicker women are able to become pregnant, Dr. Langer-Gould said, adding that how women with MS fare through pregnancy and in the postpartum period is changing over time as well. She and her colleagues’ experience with pregnancy in a cohort of women with MS in the Kaiser Permanente care system, where she is a clinical neurologist and regional research lead, revealed a relapse rate of 8.4%. “So it was pretty rare for a woman to have a relapse during pregnancy,” Dr. Langer-Gould said.

Most women with MS who become pregnant, whether their care is received in a referral center or is community based, are now doing so while on a disease-modifying therapy (DMT), Dr. Langer-Gould said. On these highly effective treatments, “women who were too sick to get pregnant are now well controlled and having babies.”

As more women with MS become pregnant, more conversations about breastfeeding will inevitably crop up, she said. And the discussion about breastfeeding has now begun to acknowledge the “strong benefits to mom and the baby of not just breastfeeding, but longer breastfeeding,” as well.

“Because of this baby-friendly push in a lot of hospitals in the United States, where they’re trying to encourage all women to breastfeed,” a full 87% of women breastfed their infants at least some of the time, and over a third of women (35%) breastfed exclusively for at least 2 months, Dr. Langer-Gould said.

“There’s no one clear explanation of why the women seem to be healthier and doing better through pregnancy as a group, but it’s probably a combination of having milder disease, breastfeeding more, and they’ve got better controlled disease before pregnancy,” she said.


At least eight studies to date have examined the relationship between postpartum MS relapses and breastfeeding, Dr. Langer-Gould said.

“The thing to take away ... is that, even though we’ve studied this many, many times, no one can show that it’s harmful,” she said. For mothers who want to breastfeed, “you can support them in the breastfeeding choice, because they are not going to have more severe disease because of that.”

Whether breastfeeding is exclusive or not has not always been tracked in studies of childbearing women with MS, but when it was captured in the data, exclusive breastfeeding has exerted a protective effect, with about a 50% reduction in risk for postpartum relapse seen in one study (JAMA Neurol. 2015 Oct;72[10]:1132-8).

There is a hormonal rationale for exclusive breastfeeding exerting a protective effect on MS: With exclusive breastfeeding comes more frequent, intense suckling, with more profound elevations in prolactin, and larger drops in follicle-stimulating hormone, luteinizing hormone, progesterone, and estradiol. All these hormonal changes work together to produce more prolonged amenorrhea and anovulation, Dr. Langer-Gould said, with potentially beneficial immunologic effects.

When other, more general maternal and infant health benefits of breastfeeding also are taken into account, there’s strong evidence for the benefits of breastfeeding for women with MS whose medication profile allows them to breastfeed, she said.

However, the “treatment” effect of exclusive breastfeeding is only effective until the infant starts taking regular supplemental feedings, including the introduction of table food at around 6 months of age. “Once regular supplemental feedings are introduced, relapses return,” Dr. Langer-Gould said.

There is some suggestion that, in women without MS, prolonged breastfeeding may be associated with reduced risk of MS. In the MS Sunshine study, breastfeeding for 15 months or longer decreased the risk of later MS by 23%-53% (Nutrients. 2018 Feb 27;10[3]:268). The investigators, led by Dr. Langer-Gould, summed the total months of breastfeeding across all children, so that the 15-month threshold could be reached by breastfeeding one child for 15 months, or three children for 5 months each. “It’s a single study; I wouldn’t make too much out of it,” Dr. Langer-Gould said.

Open questions still remain, she said: “So far, no one has been able to demonstrate a clear beneficial effect in reducing the risk of postpartum relapse if they resume their DMT early in the postpartum period.” Dr. Langer-Gould noted that the literature in this area is hampered by heterogeneity and by the fact that newer, more highly active DMTs have not been well studied.

Also, the link between postpartum relapses and long-term prognosis is not completely delineated. Indirect evidence, she said, points to a postpartum relapse as being “overall, a low-impact event.”

Dr. Langer-Gould reported that she has been the site principal investigator for clinical trials sponsored by Roche and Biogen.
