Non-significant efficacy of icotinib plus pleurodesis in epidermal growth factor receptor positive mutant lung cancer patients after malignant pleural effusion drainage compared to icotinib alone.

ABSTRACT:

Background

To investigate the efficacy and safety of icotinib plus pleurodesis or icotinib alone in epidermal growth factor receptor (EGFR) positive mutant lung cancer patients after malignant pleural effusion (MPE) drainage.

Methods

In this retrospective study from initially reviewed case reports of 230 lung adenocarcinoma patients with MPE who were EGFR mutation positive and treated in our hospital between Jan 2014 and Dec 2016 consecutively, 51 patients who met the inclusion criteria were divided into treated with oral icotinib plus pleurodesis and without pleurodesis after pleural effusion drainage groups. Case records including patient gender, age, smoking status and local treatments, as well as adverse events were collected and retrospectively analyzed. The clinical outcomes which were measured by progression free survival (PFS), objective response rate (ORR) & adverse reactions were analyzed by a Kaplan-Meier curve and a log-rank test after follow-ups.

Results

The median PFS of patients who received icotinib plus pleurodesis was 8.4 months, while the median PFS of icotinib alone patients was 9.0 months (P=0.996, χ²=7.241). Similarly, the ORR for MPEs, with or without pleurodesis were not significantly difference (64.29% vs. 67.57%, P=0.824, χ²=0.049). Adverse reactions of pleurodesis were mainly fever, chest pain, gastrointestinal reactions and myelosuppression.

Conclusions

Our results suggested that pleurodesis after MPE drainage had no difference on outcomes of icotinib therapy patients. However, pleurodesis may increase some adverse reactions, which might be inconvenient for patients in clinical practice.

Project description:BackgroundTunnelled pleural catheters used to treat malignant pleural effusions may achieve pleurodesis. We aimed to identify factors associated with higher pleurodesis rates and earlier catheter removal.MethodsWe retrospectively reviewed a prospective database of tunnelled pleural catheters inserted consecutively between May 2006 and June 2013 for confirmed malignant pleural effusion. The cohort included patients who underwent medical thoracoscopy. Clinical, radiologic and pleural fluid data were recorded. We used logistic regression and Cox regression to assess rates of and days to pleurodesis, respectively.ResultsWe analyzed data for 1071 tunnelled pleural catheters in 956 patients. Increased rates of pleurodesis were associated with lymphoma (odds ratio [OR] 3.49, 95% confidence interval [CI] 1.93-6.33), ovarian cancer (OR 2.93, 95% CI 1.68-5.11), Eastern Cooperative Oncology Group Scale of Performance Status grade 2 or less (OR 2.79, 95% CI 1.79-4.34), medical thoracoscopy (OR 2.21, 95% CI 1.28-3.85), protein level (OR 1.03, 95% CI 1.01-1.06), albumin level (OR 1.07, 95% CI 1.03-1.12) and percent eosinophils (OR 1.04, 95% CI 1.00-1.07). Reduced rates of pleurodesis were associated with gastrointestinal cancers (OR 0.41, 95% CI 0.19-0.87), hydropneumothorax on the postdrainage chest radiograph (OR 0.62, 95% CI 0.41-0.94) and percent other cells on cell count (OR 0.98, 95% CI 0.97-0.99). Earlier pleurodesis was associated with ovarian cancer (hazard ratio [HR] 1.48, 95% CI 1.06-2.08), medical thoracoscopy (HR 1.45, 95% CI 1.10-1.92), protein level (HR 1.03, 95% CI 1.01-1.04) and percent eosinophils (HR 1.02, 95% CI 1.00-1.04). Delayed pleurodesis was associated with breast cancer (HR 0.61, 95% CI 0.46-0.81), hydropneumothorax with 80% or less lung expansion (HR 0.55, 95% CI 0.38-0.80) and percent other cells (HR 0.99, 95% CI 0.98-1.00).InterpretationClinicians should consider numerous factors to predict the probability of and timing to pleurodesis with tunnelled pleural catheters.

Project description:BackgroundMalignant pleural effusion (MPE) affects approximately 150,000 patients in the United States each year and usually signifies advanced-stage cancer. The optimal treatment remains a challenge but indwelling pleural catheters (IPC) offer several advantages and may help achieve spontaneous pleurodesis (SP) in some patients.ObjectivesWe aim to investigate the predictors of SP among patients with MPE, particularly in a resource-limited community-based safety net hospital.DesignThis is a retrospective cohort study done at a community-based safety net hospital.MethodsAdults diagnosed with or suspected of having MPE between January 2015 and December 2023 who underwent IPC placement were included. Data was collected retrospectively from December 2023 to June 2024. Data encompassed demographics, imaging, post-procedural complications, pleural fluid analysis, oncology treatment history, and utilization of medical thoracoscopy without chemical pleurodesis (MTWCP) for diagnosis.ResultsA total of 173 patients underwent IPC insertion. Most of our patients were women (64.2%), and Latin American (65.9%), with a mean age of 55.3 years. The most common type of primary cancer was breast (28.9%) followed by lung (23.1%) and lymphoma (6.9%). Pleural fluid characteristics such as glucose, eosinophils, Lactate Dehydrogenase (LDH), and protein concentration were not significantly associated with SP. Most patients had low Eastern Cooperative Oncology Group scores of 0-2 (64.6%) and low LENT (Lactate Dehydrogenase (L), Eastern Cooperative Oncology Group (E) Performance Score, Neutrophil-to-Lymphocyte Ratio (N), and Tumor type (T) score) scores of 0-4 (59%). Lower scores (better functional status) were significantly associated with SP. Post-IPC chemotherapy and/or radiotherapy and immunotherapy were significantly associated with SP, adjusted odds ratio (OR) 7.295 (95% CI: 3.05-17.4, p = 0.001) and adjusted OR 6.261 (95% CI: 2.73-14.36, p = 0.001) respectively. MTWCP was also a predictor of SP with an adjusted OR of 4.031 (95% CI: 1.452-11.19, p = 0.007).ConclusionOur study is the first to assess predictors of SP in a resource-limited safety net hospital representing under-represented and underserved patients. We identify several factors associated with higher rates of SP such as higher functional status, MTWCP, chemotherapy, immunotherapy, and radiation post-IPC placement. The study findings can help clinicians consider IPC placement and guide them regarding the duration and possible complications of IPC. MTWCP appears to improve the success of SP. Further studies are needed to assess these findings further.

Project description:IntroductionMalignant pleural effusions (MPEs) are common. MPE causes significant breathlessness and impairs quality of life. Indwelling pleural catheters (IPC) allow ambulatory drainage and reduce hospital days and re-intervention rates when compared to standard talc slurry pleurodesis. Daily drainage accelerates pleurodesis, and talc instillation via the IPC has been proven feasible and safe. Surgical pleurodesis via video-assisted thoracoscopic surgery (VATS) is considered a one-off intervention for MPE and is often recommended to patients who are fit for surgery. The AMPLE-3 trial is the first randomised trial to compare IPC (±talc pleurodesis) and VATS pleurodesis in those who are fit for surgery.Methods and analysisA multi-centre, open-labelled randomised trial of patients with symptomatic MPE, expected survival of ≥ 6 months and good performance status randomised 1:1 to either IPC or VATS pleurodesis. Participant randomisation will be minimised for (i) cancer type (mesothelioma vs non-mesothelioma); (ii) previous pleurodesis (vs not); and (iii) trapped lung, if known (vs not). Primary outcome is the need for further ipsilateral pleural interventions over 12 months or until death, if sooner. Secondary outcomes include days in hospital, quality of life (QoL) measures, physical activity levels, safety profile, health economics, adverse events, and survival. The trial will recruit 158 participants who will be followed up for 12 months.Ethics and disseminationSir Charles Gairdner and Osborne Park Health Care Group (HREC) has approved the study (reference: RGS356). Results will be published in peer-reviewed journals and presented at scientific meetings.DiscussionBoth IPC and VATS are commonly used procedures for MPE. The AMPLE-3 trial will provide data to help define the merits and shortcomings of these procedures and inform future clinical care algorithms.Trial registrationAustralia New Zealand Clinical Trial Registry ACTRN12618001013257 .
