Background: Automatic stapling devices are commonly utilized in pulmonary resections, including sublobar segmentectomy. Large tumors can develop around the staple line, posing challenges in distinguishing them from cancer recurrence or inflammatory changes. In this report, we present two cases of symptomatic staple granulomatous lesion effectively managed with medications.

Background: 2-[F] Fluoro-D-deoxyglucose positron emission tomography (FDG-PET) is an appropriate diagnostic procedure for staging lung cancer. However, accurate evaluation of lymph node (LN) metastases by PET is controversial owing to false-positive/-negative FDG uptake results. The prognostic significance of both false-negative and false-positive LNs on FDG-PET remains to be determined.

Introduction: 2-[F] Fluoro-d-deoxyglucose (FDG) positron emission tomography (PET) is a relevant diagnostic procedure for staging lung cancer. However, accurate evaluation of lymph node metastases by PET is controversial because of false-positive FDG uptake.

Patients And Methods: A total of 245 patients with lung cancer were retrospectively analyzed.

Background: A bronchopleural fistula (BPF) can lead to empyema and death after pulmonary resection. A minor leakage from a BPF has been reported to be successfully closed endobronchially, although thoracoplasty is usually needed.

Case Presentation: A case of successful thoracoscopic BPF closure using an omental flap in a 74-year-old man with emphysema who developed a BPF after right lower lobectomy for lung cancer is reported.

Background: It is shown that low-dose computed tomography (CT) screening is useful for a reduction in lung-cancer-specific mortality in heavy smokers. However, the information about effectiveness according to the histological types of lung cancer has not been adequately investigated especially small cell lung cancer (SCLC). The present study was performed to see the clinical benefit of CT screening in patients with SCLC following thoracotomy.

Purpose: The indications for pulmonary resection in elderly patients with lung cancer concomitant with another disease are unclear. We conducted this retrospective study to establish the risk factors of complications and survival to improve patient selection.

Methods: The subjects were 295 patients aged ≥ 75 years, who underwent pulmonary resection for lung cancer.

The purpose of this study was to evaluate the efficacy of adjuvant chemotherapy with three courses of cisplatin and vindesine, in comparison to observation only, for N2 non-small cell lung cancer that had been completely resected. Patients with pathologically demonstrated mediastinal lymph node metastasis (N2), who had undergone complete resection, were randomized to observation or adjuvant chemotherapy (cisplatin 80 mg/m2 on day 1; vindesine 3 mg/m2 on days 1 and 8: x3 courses). Cycles started within 6 weeks after complete resection and were repeated every 4 weeks.
