RESUMO

Surgery plays a central role in the diagnosis, staging, and management of pleural mesothelioma. Achieving an accurate diagnosis through surgical intervention and identifying the specific histologic subtype is crucial for determining the appropriate course of treatment. The histologic subtype guides decisions regarding the use of chemotherapy, immunotherapy, or multimodality treatment. The goal of surgery as part of multimodality treatment is to accomplish macroscopic complete resection with the eradication of grossly visible and palpable disease. Over the past two decades, many medical centers worldwide have shifted from performing extra-pleural pneumonectomy (EPP) to pleurectomy decortication (PD). This transition is motivated by the lower rates of short-term mortality and morbidity associated with PD and similar or even better long-term survival outcomes, compared to EPP. This review aims to outline the role of surgery in diagnosing, staging, and treating patients with pleural mesothelioma.

RESUMO

Background: Pleural mesothelioma (PM) is an uncommon and extremely aggressive malignancy associated with past exposure to asbestos. The low representation of women among PM patients is likely due to differences in occupational asbestos exposure. Due to the controversial role of female sex as a prognostic factor in PM, the study aims to evaluate the survival of females treated with lung-sparing surgery. We present a cohort of 114 consecutive female patients with PM who underwent intended extended pleurectomy decortication (ePD) over 11 years in a high-volume single institution. Methods: All women from 2007-2017 who underwent intended ePD were enrolled in the study. Data on clinical, operative, and outcome were collected. Kaplan-Meier estimators and log-rank tests were employed to assess the overall survival, and Cox regression models were utilized to analyze prognostic factors. Results: During the study period, 454 patients underwent thoracotomy with intended ePD in a single institution. There were 114 females (25%), and macroscopic complete resection (MCR) was achieved in 97 (85.1%). The median age was 65 years, histology was epithelioid in 81 (71.0%), biphasic in 31 (27.2%), and sarcomatoid in 2 (1.8%). The 30- and 90-day mortality were 3.5% and 6.1%, respectively. Median survival in females was 38 months, and 5-year survival was 28.2%. The median survival and 5-year survival rate for patients with epithelioid histology and MCR were 44.4 months and 36.4%, respectively. In a univariate analysis, several factors were found to be associated with patient overall survival including MCR [hazard ratio (HR): 0.3, P<0.001], early T status (HR: 1.6, P=0.03), adjuvant therapy (HR: 0.5, P=0.006), intraoperative heated chemotherapy (IOHC) (HR: 0.8, P=0.03), age (HR: 1.02, P=0.03) and epithelioid histology (HR: 0.5, P=0.009). Conclusions: For women with epithelioid PM undergoing intended ePD within a multimodal setting, prolonged survival is anticipated.

RESUMO

Non-small cell lung cancer (NSCLC) is the most common pulmonary malignancy, frequently diagnosed at an advanced stage (III/IV). Patients in the Locally Advanced Stage Subgroup (IIIA) are relatively few, yet compose heterogenic phenotypes, posing a diagnostic and treating challenge, leading to a lack of clinical guidelines regarding the optimal standard of care. Several approaches exist, with a general agreement that a combined oncological and surgical modality approach is required. In this current retrospective descriptive study, patients with operable stage IIIA NSCLC who underwent surgery between 2013 and 2020 were evaluated on several aspects, including the initial diagnosis, neoadjuvant regimens, outcomes of surgical intervention, and overall survival at 2 years and 5 years following treatment. A total of 35 patients had neoadjuvant oncological treatment (mostly chemoradiation therapy) prior to surgery, out of which 28 patients were diagnosed with stage IIIA NSCLC. In post-operative assessment of pathological staging, downstaging was reported in 19 patients, of which 25% of cases were defined as a complete pathological response. The 2-year overall survival rate was 65% and the 5-year overall survival rate was 62%. The main pattern of disease recurrence was distant metastasis.
