Compared with patients who underwent that was guided by symptoms, patients who underwent once-daily drainage had similar breathless scores but an increased rate of spontaneous pleurodesis and better quality of life scores, according to recent research published in the Lancet Respiratory Medicine.
“In patients in whom pleurodesis is an important goal (e.g., those undertaking strategies involving an indwelling pleural catheter plus pleurodesing agents), aggressive drainage should be done for at least 60 days,” Sanjeevan Muruganandan, FRACP, MBBS, from Sir Charles Gairdner Hospital in Perth, Australia, and his colleagues wrote in their study. “Future studies will need to establish if more aggressive (e.g., twice daily) regimens for the initial phase could further enhance success rates.”
Dr. Muruganandan and his colleagues evaluated 87 patients with symptomatic malignant pleural effusions between July 2015 and January 2017 from 11 centers in Australia, New Zealand, Hong Kong, and Malaysia in the randomized controlled AMPLE-2 trial, in which patients received either once daily (43 patients) or symptom-guided (44 patients) drainage for 60 days with a 6-month follow-up. Patients were excluded if they had a pleural infection, were pregnant, had a previous pneumonectomy or ipsilateral lobectomy, had “significant loculations likely to preclude effective fluid drainage,” or had an estimated survival of less than 3 months. Patients were identified and grouped based on whether they had mesothelioma- or nonmesothelioma-type cancer, with cancer type being minimalized during randomization.
At 60 days, patients in the aggressive daily drainage group had a mean daily breathless score of 13.1 mm (geometric means; 95% confidence interval, 9.8-17.4), compared with a mean of 17.3 mm (95% CI, 13.0-22.0) in the symptom-guided drainage group. In the aggressive drainage group, 16 of 43 patients (37.2%) achieved spontaneous pleurodesis at 60 days, compared with 11 of 44 patients (11.4%) in the symptom-guided drainage group (P = .0049). At 6 months, 19 of 43 (44.2%) patients in the aggressive drainage group had spontaneous pleurodesis, compared with 7 of 44 patients (15.9%; P = .004) in the symptom-guided drainage group (hazard ratio, 3.287; 95% CI, 1.396-7.740; P = .0065).
In each group, the investigators noted adverse events: 11 of 43 (25.6%) patients in the aggressive drainage group and 12 of 44 patients (27.3%) in the symptom-guided drainage group reported a severe adverse event. There were no significant differences in mortality, pain scores, and hospital stay between the groups. Regarding quality of life, the investigators found patients in the aggressive drainage group reported better scores using the EuroQoL-5 Dimensions-5 Levels assessment (estimated means, 0.713; 95% CI, 0.647-0.779) than did patients in the symptom-guided group (0.601; 95% CI, 0.536-0.667), with an estimated difference in means of 0.112 (95% CI, 0.0198-0.204; P = .0174).
The investigators suggested that aggressive drainage may have some unmeasured benefits. “Daily removal of the fluid might have provided benefits in symptoms not captured with our breathlessness and pain measurements. The higher pleurodesis rate, with resultant freedom from fluid (and symptom) recurrence and of the catheter, might have contributed to the better reported quality of life. Additionally, it has been suggested that indwelling pleural catheter drainage gives patients an important sense of control when they are feeling helpless with their advancing cancer.”
They concluded, “For patients whose primary care aim is palliation (e.g., those with very limited life expectancy or significant trapped lung where pleurodesis is unlikely), our data show that symptom-guided drainage offers an effective means of breathlessness control without the inconvenience and costs of daily drainages. The ability to predict the likelihood of pleurodesis will help guide the choice of regimen and should be a topic of future studies.”
