Objectives The role of postoperative mediastinal radiotherapy in completely resected non-small cell lung cancer (NSCLC) and pathological N2 disease is controversial. In clinical practice, not all lung cancer patients with histologically confirmed N2 disease and a high risk for local recurrence are able to undergo postoperative concurrent radio/chemotherapy due to their physical condition or postoperative morbidities. Mediastinal radiotherapy is less compromising than a combination of radio/chemotherapy and seems likely to be tolerable for limited patients to achieve better local tumor control. Materials and Methods All patients included in this retrospective analysis were excluded from postoperative adjuvant combination chemo/radiotherapy due to their comorbidity, advanced age, or a complicated postoperative course. Three-dimensional conformal radiotherapy of the mediastinal lymph node stations (mean dose: 50 Gy; range: 50-54 Gy) in patients with R0 resection, additional boost of 10 Gy in patients with R1 or R2 resection, was performed postoperatively. Results A total of 110 patients were included in this analysis. Mean survival was 25.5 ± 19.2 months. The 1-, 3-, and 5-year survival was 75.4, 38.7, and 26.2%, respectively. Postoperative complications and the development of distant metastases did not correlate (p = 0.7). Distant metastases proved to be a significant prognostic factor of survival (p < 0.0001). Local recurrence was seen in a total of three patients (2.7%). Five-year survival of patients developing major postoperative complications was significantly inferior (p = 0.04) to those without postoperative complications. The extent of surgery had a significant impact on survival-5-year survival after lobectomy was significantly longer than after pneumonectomy (p = 0.029). R1 resection had no significant impact on the survival rates (p = 0.67). Discussion Stage III-N2 NSCLC patients with multiple comorbidities or a complicated postoperative course after surgery may benefit from modern mediastinal radiotherapy. Surgery and postoperative mediastinal radiotherapy can achieve local tumor control. Distant metastases have the highest impact on the prognosis. Pneumonectomy, however, should be avoided in stage III NSCLC, when possible., (Georg Thieme Verlag KG Stuttgart · New York.)

Background: Patients with a forced expiratory volume in 1 s (FEV1) below 20% of the predicted normal values (pred.) and either homogeneous emphysema or low diffusing capacity for carbon monoxide (DLCO) have a high risk for adverse events including death when undergoing surgical lung volume reduction., Objectives: We hypothesized that selected patients can benefit from endoscopic lung volume reduction (eLVR) despite a very low FEV1., Methods: This study is a retrospective analysis of consecutive patients with severe airflow obstruction, an FEV1 ≤20% of pred., and low DLCO who were treated by eLVR with endobronchial valves (EBV) between June 2012 and January 2015. Pre- and postinterventional lung function parameters, the 6-min walking test (6-MWT) distance, adverse events, and follow-up were recorded., Results: In 20 patients, there was an overall improvement in lung function with an increase in FEV1 (16.97-21.03% of pred.) and a decrease in residual volume (322-270% of pred.) and total lung capacity (144-129.06% of pred.). The 6-MWT distance improved (from 239 ± 77 to 267± 97 m overall, and from 184 ± 50 to 237 ± 101 m if patients developed an atelectasis of the target lobe). Pneumothorax occurred in 5 of the 20 patients (25%). 30-day mortality was 0%, and all patients survived to discharge., Conclusions: The patients benefitted moderately from EBV treatment despite an initially low FEV1. Some patients improved remarkably. EBV treatment in patients with an FEV1 ≤20% of pred. is generally feasible and safe. The greatest risk is pneumothorax with prolonged chest tube duration., (© 2016 S. Karger AG, Basel.)

Sleeve lobectomy is an established surgical procedure in patients with lung cancer. Usually the only surgical alternative would be a pneumonectomy. This article describes the perioperative risks and functional results in patients after sleeve lobectomy compared to pneumonectomy and typical lobectomy.There were only minor differences with respect to postoperative morbidity comparing the different procedures but the mortality rate was higher following pneumonectomy. Bronchopleural fistula rates were also similar comparing lobectomy and sleeve lobectomy but elevated following pneumonectomy. Bronchovascular fistulas after sleeve lobectomy are potentially life-threatening. Postoperative pulmonary function tests showed similar values for lobectomy and sleeve lobectomy patients and were considerably better than following pneumonectomy.Whenever possible sleeve lobectomy should take preference over pneumonectomy.
