In patients with MPM treated with P-based chemotherapy, low TS protein levels are predictive of improved TTP and OS. The role of TS assessment is worth of prospective validation in future studies on MPM.
A recommendation to collapse both clinical and pathological T1a and T1b into a T1 classification will be made for the eighth edition staging system. Simple measurement of pleural thickness has prognostic significance and should be examined further with a view to incorporation into future staging.
Our data suggest that patients with good prognostic factors had a similar survival whether they received medical therapy only, P/D, or EPP. The modest benefit observed after surgery during medical treatment requires further investigation, and a large multicenter, randomized trial, testing P/D after induction chemotherapy versus chemotherapy alone in MPM patients with good prognostic factors, is needed.
The number of patients requiring tracheal intubation rose dramatically in March and April 2020 with the COVID-19 outbreak. Our thoracic surgery department has seen an increased incidence of severe pneumomediastinum referred for surgical opinion in intubated patients with COVID-19 pneumonitis. Here we present a series of five cases of severe pneumomediastinum requiring decompression therapy over a 7-day period in the current COVID-19 outbreak. We hypothesise that the mechanism for this is the aggressive disease pathophysiology with an increased risk of alveolar damage and tracheobronchial injury along with the use of larger bore tracheal tubes and higher ventilation pressures. We present this case series in order to highlight the increased risk of this potentially life-threatening complication among the COVID-19 patient cohort and offer guidance for its management to critical care physicians.
To compare the outcomes of two different multimodality regimens involving neoadjuvant chemotherapy, extrapleural pneumonectomy (EPP) and adjuvant radiotherapy versus pleurectomy/decortication (P/D), hyperthermic pleural lavage with povidone-iodine, and adjuvant chemotherapy in patients with malignant pleural mesothelioma. Methods: Nonrandomized prospective study of patients treated by multimodality therapy and operated on between January 2004 and June 2011. Second-line treatments were administered when appropriate. Survival and prognostic factors were analyzed by the Kaplan Meier method, log rank test, and Cox regression analysis. Results: Twenty-five consecutive patients received neoadjuvant chemotherapy, 22 underwent EPP, and 17 received adjuvant radiotherapy. over the same period, 54 consecutive patients underwent P/D and hyperthermic pleural lavage and received prophylactic radiotherapy and adjuvant chemotherapy. The 30-day mortality rate was 4.5% in the EPP group and nil in the P/D group. Fifteen patients (68%) in the EPP group and 15 (27.7%) in the P/D group experienced complications. There were no differences between the EPP and P/D groups for age, sex, histology, pathologic stage, and nodal status. Trimodality therapy was completed by 68% of the patients in the EPP group and 100% in the P/D group. Survival was significantly better in the P/D group: median survival was 23 months versus 12.8 months, 2-year survival was 49% versus 18.2 %, and 5-year survival was 30.1% versus 9%, respectively (p = 0.004). At multivariate analysis, epithelioid histology, P/D, and completeness of resection were independent prognostic factors. Conclusions: In our experience, P/D, hyperthermic pleural lavage with povidone-iodine, and adjuvant chemotherapy were superior to neoadjuvant chemotherapy, EPP, and adjuvant radiotherapy.
Our data show that integrated PET/CT provides high specificity but low sensitivity and accuracy in intrathoracic nodal staging of NSCLC patients and underscore the continued need for surgical staging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
