Endosonography With or Without Confirmatory Mediastinoscopy for Resectable Lung Cancer:A Randomized Clinical Trial

PURPOSE:Resectable non-small-cell lung cancer (NSCLC) with a high probability of mediastinal nodal involvement requires mediastinal staging by endosonography and, in the absence of nodal metastases, confirmatory mediastinoscopy according to current guidelines. However, randomized data regarding immediate lung tumor resection after systematic endosonography versus additional confirmatory mediastinoscopy before resection are lacking.METHODS:Patients with (suspected) resectable NSCLC and an indication for mediastinal staging after negative systematic endosonography were randomly assigned to immediate lung tumor resection or confirmatory mediastinoscopy followed by tumor resection. The primary outcome in this noninferiority trial (noninferiority margin of 8% that previously showed to not compromise survival, Pnoninferior &lt;.0250) was the presence of unforeseen N2 disease after tumor resection with lymph node dissection. Secondary outcomes were 30-day major morbidity and mortality.RESULTS:Between July 17, 2017, and October 5, 2020, 360 patients were randomly assigned, 178 to immediate lung tumor resection (seven dropouts) and 182 to confirmatory mediastinoscopy first (seven dropouts before and six after mediastinoscopy). Mediastinoscopy detected metastases in 8.0% (14/175; 95% CI, 4.8 to 13.0) of patients. Unforeseen N2 rate after immediate resection (8.8%) was noninferior compared with mediastinoscopy first (7.7%) in both intention-to-treat (Δ, 1.03%; UL 95% CIΔ, 7.2%; Pnoninferior =.0144) and per-protocol analyses (Δ, 0.83%; UL 95% CIΔ, 7.3%; Pnoninferior =.0157). Major morbidity and 30-day mortality was 12.9% after immediate resection versus 15.4% after mediastinoscopy first (P =.4940).CONCLUSION:On the basis of our chosen noninferiority margin in the rate of unforeseen N2, confirmatory mediastinoscopy after negative systematic endosonography can be omitted in patients with resectable NSCLC and an indication for mediastinal staging.</p

Surgery in mesothelioma: where do we go after MARS?

The role of surgery in the management of malignant pleural mesothelioma remains controversial. Surgical resection consists of different procedures for diagnostic or therapeutic reasons. The latter includes either an extrapleural pleuropneumonectomy (EPP) or lung-sparing operations like debulking of the parietal and visceral pleura by pleurectomy/decortication (P/D) or extended pleurectomy/decortication, in which further debulking of the diaphragm or pericardium is included. Because of the modest outcome of surgery as single-modality therapy, combinations of chemotherapy, surgery, and radiation therapy were initiated as a new treatment strategy to improve prognosis. The observations that patients treated with P/D had an equal to better outcome than those treated with EPP, and that EPP with perioperative chemotherapy was better than EPP alone, raises the issue whether performing a P/D with perioperative chemotherapy would result in a further improvement of outcome with a lower operative mortality than with EPP and perioperative chemotherapy. This is the rationale for the next European Organisation for Research and Treatment of Cancer trial exploring the feasibility of P/D with perioperative chemotherapy

Mesothelioma treatment: are we on target : a review

AbstractTargeted treatment is a therapy directed at a specific molecular target close to a hallmark of cancer. The target should be measurable with a biomarker and measurement of the target should correlate with clinical outcome when targeted treatment is administered. Current clinical guidelines do not recommend targeted or biological therapy in MPM. However, since these recommendations came out, new agents have been investigated in MPM. This review updates the use of targeted and biological treatment in patients with mesothelioma
