Key clinical point: Higher preoperative vitamin D levels were associated with lower odds of a complicated surgical course in older patients with colorectal cancer (CRC) undergoing resection, with deficient preoperative vitamin D levels being associated with poor overall survival irrespective of age.

Major finding: Higher vitamin D levels prior to resection were associated with a reduced risk for major complications after surgery in patients aged ≥70 years (odd ratio 0.51; 95% CI 0.27-0.95) but not in those aged <70 years, with deficient (<25 nmol/L) vs sufficient (>50 nmol/L) levels of vitamin D being associated with reduced survival irrespective of age (hazard ratio 3.39; P = .019).

Study details: Findings are from an ongoing prospective cohort study including 398 patients with stage I-III CRC who underwent surgical resection, of which 208 patients were aged ≥70 years.

Disclosures: This study was funded by the VELUX Foundation, Denmark, and the Beckett Foundation, Denmark. The authors declared no competing financial interests.

Key clinical point: Consolidation chemotherapy (CC) with 1-2 cycles of capecitabine after neoadjuvant chemoradiotherapy (NCRT) without extending the interval between NCRT and surgery was safe and improved the complete response (CR) rate without improving long-term outcomes in high-risk patients with locally advanced rectal cancer (LARC).

Major finding: After propensity matching, the CR rate was significantly higher in the group receiving vs not receiving CC after NCRT (27.6% vs 16.2%; P = .045); however, the 3-year non-regrowth disease-free survival (P = .865), overall survival (P = .612), and grade ≥2 acute toxicity (P = .492) did not differ significantly between the groups.

Study details: Findings are from a retrospective study of 265 high-risk patients with LARC who either received (n = 136) or did not receive (n = 129) CC after NCRT.

Disclosures: This study was supported by the Beijing Municipal Science and Technology Commission, Capital’s Funds for Health Improvement and Research, and National Natural Science Foundation, China. The authors declared no conflicts of interest.

Key clinical point: A >8-week interval between neoadjuvant chemoradiotherapy (nCRT) and subsequent surgery improved tumor regression grade (TRG) compared with a 6-8-week interval in patients with locally advanced rectal cancer (LARC), while pathological complete response (pCR) and survival outcomes were similar between the groups.

Major finding: The pCR rate (P = .836), 5-year relapse-free survival (P = .569), and 5-year overall survival (P = .956) were not significantly different between the 6-8-week and >8-week groups; however, TRG was significantly better in the >8-week group (P = .004).

Study details: Findings are from a retrospective study including 770 patients with LARC who had undergone total mesorectal excision either 6-8 weeks (n = 502) or >8 weeks (n = 268) after long‐course nCRT.

Key clinical point: Simultaneous vs delayed resection of synchronous liver metastasis (SLM) was associated with longer survival rates in patients with colorectal cancer (CRC) with KRAS wild-type tumors but not in those with KRAS sequence variation.

Major finding: Perioperative complications within 60 days of surgery were not significantly different in the simultaneous vs delayed resection group (P = .89), but simultaneous vs delayed resection was associated with better 5-year overall survival (hazard ratio [HR] 1.61; P < .001) and cancer-specific survival (HR 1.62; P = .003) in patients with KRAS wild-type tumors, but not in those with overall KRAS sequence variation.

Study details: This retrospective study included 1569 patients with CRC with or without KRAS sequence variation who underwent simultaneous (n = 512) or delayed (n = 1057) resection of SLM.

Disclosures: This study was supported by a grant from Shanghai Shenkang Clinical Science and Technology Innovation Project, China. No conflicts of interest were reported.

Key clinical point: Laparoscopic surgery for low rectal cancer when performed by experienced surgeons yielded short-term pathological outcomes, comparable to open surgery, along with a higher rate of sphincter preservation and a shorter duration of hospitalization.

Major finding: Laparoscopic vs open surgery was associated with similar rates of mesorectal excision (P = .78), negative circumferential resection margin (P = .09), negative distal resection margin (P = .36), postoperative complications (P = .07), and median number of retrieved lymph nodes (P = .39), along with a higher sphincter preservation rate (P = .03) and shorter hospitalization duration (P = .008).

Study details: Findings are from LASRE, a noninferiority randomized clinical trial, including 1039 patients scheduled for curative-intent resection of low rectal cancer who were randomly assigned to undergo laparoscopic (n = 712) or open (n = 358) surgery.

The three PPH articles examine the use of preventive B-Lynch suture, risk factors for failure of intrauterine tamponade, and trend changes in risk factors for PPH. Kuwabara and colleagues looked at the effectiveness of preventative B-Lynch sutures in patients at high risk for PPH. Their retrospective observational study included 38 of 663 patients who underwent cesarean section (CS) who received the B-Lynch procedure at their tertiary perinatal medical center in Gifu, Japan, between January 2019 and May 2021. Overall, 92% of patients who received the B-Lynch suture showed no apparent postoperative bleeding within 2 hours after the CS. A total of 24 patients required blood transfusion, none required hysterectomy, and only one patient with a twin pregnancy required additional treatment because of secondary PPH 5 days after the CS. This suggests that earlier use of B-Lynch sutures could be considered in patients at high risk for atony.

Gibier and colleagues examined risk factors for uterine tamponade failure in women with PPH. This was a population-based retrospective cohort study of 1761 women with deliveries complicated by PPH who underwent intrauterine tamponade within 24 hours of PPH to manage persistent bleeding. They noted that the intrauterine tamponade failure rate was 11.1%. Risk for intrauterine tamponade failure was higher in women with CS (adjusted odds ratio [aOR] 4.2; 95% CI 2.9-6.0), preeclampsia (aOR 2.3; 95% CI 1.3-3.9), and uterine rupture (aOR 14.1; 95% CI 2.4-83.0). They concluded that CS, preeclampsia, and uterine rupture were significant risk factors for failures in this procedure.

Sade and colleagues examined trend changes in the individual contribution of risk factors for PPH over more than two decades. Their population-based, retrospective, nested, case-control study included 285,992 pregnancies and suggested that, in their hospital setting in Israel, risks from perineal or vaginal tears were increasing while large-for-gestational-age fetuses decreased and other risk factors remained stable.

Finally, Wu and colleagues examined incidence and outcomes of AHRCP diseases during pregnancy and the puerperium. This observational analysis examined 41,174,101 patients hospitalized for pregnancy and during the puerperium in the National Inpatient Sample (NIS) database from January 1, 2008, to December 31, 2017. The study noted that 40,285 patients were diagnosed with AHRCP diseases during this period. The NIS is the largest publicly available all-payer database in the United States. The investigators found that the incidence of AHRCP diseases increased significantly between 2002 and 2017, especially pulmonary embolism in the puerperium. Although mortality showed a downward trend, it is still at a high level. They suggested that we should strengthen monitoring and management of AHRCP in pregnancy and puerperium, especially for Black women, those in the lowest-income households, and parturients over 35 years of age.

The study noted that 40,285 patients were diagnosed with AHRCP diseases during this period. The NIS is the largest publicly available all-payer database in the United States. The investigators found that the incidence of AHRCP diseases increased significantly between 2002 and 2017, especially pulmonary embolism in the puerperium. Although mortality showed a downward trend, it is still at a high level. They suggested that we should strengthen monitoring and management of AHRCP in pregnancy and puerperium, especially for Black women, those in the lowest-income households, and parturients over 35 years of age.

The three PPH articles examine the use of preventive B-Lynch suture, risk factors for failure of intrauterine tamponade, and trend changes in risk factors for PPH. Kuwabara and colleagues looked at the effectiveness of preventative B-Lynch sutures in patients at high risk for PPH. Their retrospective observational study included 38 of 663 patients who underwent cesarean section (CS) who received the B-Lynch procedure at their tertiary perinatal medical center in Gifu, Japan, between January 2019 and May 2021. Overall, 92% of patients who received the B-Lynch suture showed no apparent postoperative bleeding within 2 hours after the CS. A total of 24 patients required blood transfusion, none required hysterectomy, and only one patient with a twin pregnancy required additional treatment because of secondary PPH 5 days after the CS. This suggests that earlier use of B-Lynch sutures could be considered in patients at high risk for atony.

Gibier and colleagues examined risk factors for uterine tamponade failure in women with PPH. This was a population-based retrospective cohort study of 1761 women with deliveries complicated by PPH who underwent intrauterine tamponade within 24 hours of PPH to manage persistent bleeding. They noted that the intrauterine tamponade failure rate was 11.1%. Risk for intrauterine tamponade failure was higher in women with CS (adjusted odds ratio [aOR] 4.2; 95% CI 2.9-6.0), preeclampsia (aOR 2.3; 95% CI 1.3-3.9), and uterine rupture (aOR 14.1; 95% CI 2.4-83.0). They concluded that CS, preeclampsia, and uterine rupture were significant risk factors for failures in this procedure.

Sade and colleagues examined trend changes in the individual contribution of risk factors for PPH over more than two decades. Their population-based, retrospective, nested, case-control study included 285,992 pregnancies and suggested that, in their hospital setting in Israel, risks from perineal or vaginal tears were increasing while large-for-gestational-age fetuses decreased and other risk factors remained stable.

Finally, Wu and colleagues examined incidence and outcomes of AHRCP diseases during pregnancy and the puerperium.

Lasmiditan—the first migraine treatment in the new ditan class— is a serotonin receptor agonist, similar to triptan medications. However, it is specific for the 5HT_1F receptor rather than the 5HT_1B/1D receptor. The main purpose of this specificity is that it leads to less vascular risk; specifically, this medication should be safer for populations at higher risk for vascular events, such as myocardial infarction and stroke.

Only one triptan, naratriptan, had previously been studied for the treatment of menstrual migraine, at a recommended dose of 2.5 mg twice daily as a bridge. A new study by MacGregor and colleagues looked at taking 50, 100, or 200 mg of lasmiditan vs placebo for an individual premenstrual attack.

The participants in the study were recruited from the intention-to-treat population of two prior studies for this drug, a phase 2 trial and a phase 3 trial. The menstrual calendars of the female participants were reviewed, followed by randomization into one of the four groups. Patients with chronic migraine were excluded from the study. The primary outcome was freedom from pain at 2 hours; secondary outcomes were freedom from the most bothersome symptom and reduction in pain severity.

Of the four populations followed, all three intervention groups noted significant results in freedom from pain at 2 hours compared with placebo. The 2-hour responder rate was 33.6% for the 200 mg group, 16.7% for the 50 mg and 100 mg groups, and 7.6% for the placebo group. Freedom from the most bothersome symptom and pain reduction were also significant in these populations.

Menstruation-associated migraine and worsening headache attacks due to patients' hormonal fluctuations are some of the most common issues and triggers that neurologists and headache specialists confront. Although the responder rates for freedom from pain at 2 hours were not very robust, lasmiditan does appear to be significantly effective in this population, and in those with menstrual triggers specifically. The field of headache medicine would be even better served by additional studies on both preventive and more acute medications in association with hormonal triggers.

Another very common trigger for migraine is changes in sleep patterns. An astute headache specialist will always ask about sleep quantity and quality during an initial assessment of a patient. Many headache centers have sleep-specific questionnaires that patients fill out during intake. The precise association between migraine and sleep deserves more elucidation. Duan and colleagues specifically set out to reveal whether differences in sleep quality affect migraine frequency; whether this is the same among different gender and age groups; and whether headache disability, severity, mood, and quality of life are related to underlying sleep changes independent of other factors.

A total of 134 participants with migraine and 70 without migraine or any other headache disorder were enrolled in the study. Sleep quality was assessed through The Pittsburgh Sleep Quality Index (PSQI) questionnaire. This is a commonly used self-reported questionnaire for assessing quality and quantity of sleep over the past month and is considered the standard of care in most sleep centers. The investigators here sought to determine the predictive value of the PSQI in regard to migraine. Migraine disability was assessed via the Migraine Disability Assessment (MIDAS) scale as well as the Headache Impact Test (HIT-6). Statistical analysis was performed with logistical regression, t test, and χ² squared test.

There strongest correlations between poor sleep quality and risk of migraine were found in women, patients over 35 years old, and those with lower education levels. The results revealed that the migraine group had poorer sleep quality, as well as higher anxiety and depression scores, compared with the control group. A low PSQI score (eg, poorer sleep quality) was associated with higher migraine frequency; this was independent of body mass index (BMI), weekly exercise time, and smoking or drinking history. After participants were divided into good and poor sleep quality subgroups, the PSQI score was found to increase the odds ratio of migraine by a factor of 6.

The investigators were able to show the predictive quality of the PSQI score. Worse sleep quality was found to be associated with a higher MIDAS score and HIT-6 score as well as total pain burden, pain severity, decreased quality of life, depression, and anxiety. Although most headache specialists spend a significant amount of time discussing sleep as it relates to migraine, it may be worth considering following a sleep quality scale, such as the PSQI, over time as we monitor our patients. This may allow us to take a more proactive role and be able to prognosticate our patients' migraine journey somewhat better. Although sleep triggers and associations with migraine can be very difficult to discuss and treat, this study very clearly argues for the importance of focusing on sleep with our patients.

Although the most common aura our patients with migraine experience is visual, many patients with migraine will also experience non-aura visual changes. These can range from short-lasting episodes of blurred vision, such as transient visual obscurations, or other transient visual disturbances that do not fit the criteria of aura as defined by the International Classification of Headache Disorders (ICHD).

A prior study by Tsao and colleagues had revealed that almost half of headache patients experienced some headache-related visual change, the most common of which were short-lasting flickering lights or a movable, monochromatic scotoma. As opposed to visual aura, these transient disturbances were shorter in onset and duration and typically occurred during the headache phase of a migraine attack. In the current study, Tsao and colleagues sought to determine whether the presence of these findings was associated with a different headache burden from that typically found in migraine with aura.

The participants in this study were enrolled over a 10-year period from May 2010 to July 2020. They initially underwent a visual phenomenon questionnaire and then a thorough clinical interview to determine their headache diagnosis per ICHD criteria — specifically whether they had an underlying diagnosis of migraine with aura or migraine without aura. Participants were also separately diagnosed with chronic migraine or medication overuse headache. A visual rating scale was used in the initial questionnaires. This scale posed questions about the duration of symptoms; whether the symptoms develop gradually or suddenly; and whether the visual change was a scotoma, zigzag lines, or in a unilateral or bilateral visual field. A prior study by these investigators determined this visual rating scale to be highly sensitive and specific for diagnosing migraine with aura.

Participants were also given the MIDAS questionnaire and were assessed with the HIT-6 scale, a migraine photophobia score, and the Beck Depression Inventory. A total of 12,255 patients were enrolled, 9946 with migraine, who were subdivided on the basis of diagnosis of migraine with or without aura. Blurred vision was the most common visual complaint among all migraine patients. Patients who had transient visual disturbances that did not fit the criteria of migraine with aura were noted to have a statistically significant higher headache frequency, more severe headache-related disability, a higher likelihood of developing medication overuse headache, and a greater incidence of anxiety and depression.

An important distinction that all headache specialists make is whether their patients experience migraine with or without aura. The primary purpose for this distinction is to determine the appropriateness of specific medications (estrogen or vasoconstrictive medications), as migraine aura relates to vascular risk. We usually delve deeply into whether the visual symptoms that our patients experience do or do not fit into the ICHD criteria of migraine aura. We should not discard or think less of non-aura visual disturbances; these authors argue very clearly that these kinds of visual changes can be very relevant prognostically.

Immune checkpoint inhibitors in combination with chemotherapy are part of standard treatment for patients with advanced gastroesophageal adenocarcinoma. However, not all patients benefit from immunotherapy addition. Programmed death-ligand 1 (PD-L1) expression has emerged as a useful, yet imperfect, biomarker for identifying patients who are most likely to benefit from the addition of immunotherapy. There is a need to better identify patients with higher chances of responding to these therapies, as well as a need to augment the activity that we are seeing with current approaches. Tumor mutational burden (TMB) has been previously identified as a predictive biomarker of response to immunotherapy. It is not widely used in clinical practice when treating patients with upper gastrointestinal cancers though, and it has not been extensively evaluated in this disease.

The study by Lee and colleagues evaluated the association between TMB and pembrolizumab response in patients treated in the phase 3 KEYNOTE-62 study. This was a prespecified exploratory analysis, which included 306 of 763 patients, based on TMB data availability. Although there was association between high TMB (cut-off defined as 10 mut/Mb), the benefit from pembrolizumab was most pronounced in patients with microsatellite-unstable tumors. When the analysis was limited to microsatellite-stable tumors with high TMB, the signal was attenuated and was only detected when immunotherapy was combined with chemotherapy.

Ultimately, although TMB is a predictive biomarker of response to immunotherapy, it is unlikely to significantly alter our approach to treatment of upper gastrointestinal cancers, especially when PD-L1 testing and microsatellite testing are more readily available and do not require more time- and resource-consuming next-generation sequencing when selecting first-line treatments.

Perioperative chemotherapy plays a critical role in the management of patients with early-stage gastric cancer. In the United States, perioperative FLOT (5-fluorouracil, oxaliplatin, and docetaxel) chemotherapy is the standard approach to this disease, with four cycles administered before and four cycles administered after resection.

In Korea, adjuvant chemotherapy is typically used, with 1 year of S-1 chemotherapy or 6 months of CAPOX (capecitabine/oxaliplatin) chemotherapy used most frequently. Kim and colleagues analyzed whether a shorter duration of chemotherapy (either S-1 or CAPOX) had similar outcomes. In a retrospective analysis of 20,552 patients, which included 13,614 patients who received S-1 and 6938 patients who received CAPOX, overall survival was worse in those patients who received a shorter duration of adjuvant treatment. Although this study is not directly applicable to how we approach treatment of early-stage gastric cancer in the United States, it does suggest that any modification in the duration of perioperative chemotherapy should be evaluated in prospective clinical trials, similarly to recent investigations regarding the duration on adjuvant chemotherapy in colon cancer.
