Salvage surgery to treat tumor regrowth after stereotactic body radiotherapy in primary non-small cell lung cancer.

Background: Stereotactic body radiotherapy (SBRT) is considered to be an effective and safe treatment in patients with primary lung cancer. If local recurrence is confirmed following SBRT, surgical treatment is a possibility. The present study aimed to clarify the safety and survival outcomes of salvage surgery in primary lung cancer patients with local recurrence following SBRT.

Thoracoscopic surgery versus open surgery for lung metastases of colorectal cancer: a multi-institutional retrospective analysis using propensity score adjustment†.

Objectives: Thoracoscopic surgery for lung metastasectomy remains controversial. The study aimed at determining the efficacy of thoracoscopic surgery for lung metastasectomy.

Methods: This was a multi-institutional, retrospective study that included 1047 patients who underwent lung metastasectomy for colorectal cancer between 1999 and 2014.

Early recurrence after surgical resection in patients with pathological stage I non-small cell lung cancer.

Introduction: Early recurrence is observed even in patients who undergo complete resection and had pathological (p-) stage I. Therefore, we focused on early recurrence, and attempted to elucidate the relationship between early recurrence and clinicopathological factors.

Methods: Between May 1993 and December 2005, 1201 patients with non-small cell lung cancer (NSCLC) underwent surgical treatment at our institution.

Huge mediastinal mass with SVC syndrome accompanying numerous chest wall collateral vessels.

A 47-year-old man was referred to our hospital because of dyspnea, cough and weight loss. On physical examination, marked dilatation of thoraco-superficial epigastric venous anastomosis was found. The chest wall collateral vessels revealed enlarged head-to-toe flow, suggesting complete obstruction of the SVC and one or more of the major caval tributaries, including the azygos system.

A malignant peripheral nerve sheath tumor of the mediastinum in a patient with neurofibromatosis type 1: report of a case.

Malignant peripheral nerve sheath tumor (MPNST) is rare, but its association with neurofibromatosis type 1 (NF1) is well known. A 56-year-old man with NF1 was referred to our hospital for investigation of dyspnea. Computed tomography showed a huge mass occupying the right thorax and invading the inferior vena cava.
