Lobectomy versus proton therapy for stage I non-small cell lung cancer.

OBJECTIVE: Lobectomy is the standard treatment for patients with early-stage non-small cell lung cancer (NSCLC). In recent years, an increasing number of patients with lung cancer have been treated using proton therapy (PT). We conducted a propensity score-matched analysis to compare the treatment outcomes of these 2 modalities. METHODS: We retrospectively reviewed data from 275 patients with histologically confirmed clinical stage I NSCLC who underwent lobectomy (n = 206) or PT (n = 69) at our institution from July 2013 to December 2020. The end points were overall survival (OS), cause-specific survival, recurrence-free survival (RFS), local control, regional lymph node control, and distant control. Propensity score matching was performed to reduce selection bias in the 2 groups. RESULTS: The matched cohort consisted of 59 patients who underwent lobectomy and 59 patients who underwent PT with a median follow-up period of 50 months. There were no significant differences in OS (P = .26), cause-specific survival (P = .33), RFS (P = .53), local control (P = .41), regional lymph node control (P = .98), and distant control (P = .31). In the lobectomy and PT groups, the 5-year OS rate was 85.8% and 79.1%, respectively, the RFS rate was 82.3% and 77.8%, and the local control rate was 92.1% and 96.6%. CONCLUSIONS: We found no difference in survival or disease control between lobectomy and PT in patients with histologically confirmed clinical stage I NSCLC. Despite these findings, the potential for unmeasured confounding factors remains, and randomized control trials are needed to better compare these treatment modalities.

Everolimus in combination with octreotide LAR in thymic atypical carcinoid.

Thymic atypical carcinoids are extremely rare tumors and have a poor prognosis owing to their aggressive clinical course. The efficacy of treatments other than complete surgical resection is unclear. We herein report a postoperative recurrent case of thymic atypical carcinoid treated with everolimus and octreotide long-acting repeatable (LAR). A 75-year-old woman was admitted to our department because a nodule was detected in the right lobe of thymus by annual computed tomography. The patient underwent thymothymectomy, and a diagnosis of thymic atypical carcinoid was made. One year and seven months after surgery, she developed multiple metastases in the lung, hilar and mediastinal lymph nodes, liver, and bone. Everolimus 10 mg/day was administered; however, the dose had to be reduced to 5 mg/day due to grade 3 hyperglycemia and grade 3 interstitial lung disease. Metastatic lesions other than liver metastasis markedly responded to everolimus, although the liver metastases gradually progressed. Three years and six months after surgery, she was administered octreotide LAR 30 mg per month in combination with everolimus. She has maintained stable disease for 8 months after the application of this combination therapy.

A case of resected pulmonary capillary hemangioma with a literature review.

Pulmonary hemangiomas are benign, relatively rare tumours. Because computed tomography (CT) findings show a variety of images, it is often difficult to distinguish hemangiomas from lung cancer and other benign tumours. We report a 63-year-old man who was diagnosed with a pulmonary capillary hemangioma (PCH). A right lung basal segmentectomy was performed for diagnosis and treatment. On chest CT, the lesion was shown to be a solid nodule with contrast-enhanced margins. This finding was thought to reflect the dense vascular hyperplasia of the central part of the tumour based on the pathologic findings. Although few studies involving PCH have referred to contrast-enhanced CT, the findings of contrast-enhanced CT might be a valuable indicator for diagnosing PCH.

Port site hernia repair using the VersaOne™ Fascial Closure System: a case report.

The use of laparoscopic surgery has become widespread in recent years. One of its complications is port site hernia (PHS). It can be difficult to close the fascia at the time of laparoscopy, especially in obese patients, and there is a risk of herniation through a fascial defect with incomplete closure. It is important to ascertain closure of the defect when repairing PHS to prevent recurrence. We report a 47-year-old woman who developed a PHS at the superior aspect of the umbilicus. We repaired the defect using the VersaOneTM Fascial Closure System with laparoscopic guidance. This system allows the port site to be reliably closed while observing the suture from the abdominal cavity. The incision is the same size as a port site. If the abdominal wall is thick and the PHS has a diameter of ~10 mm, this method is considered to be indicated, regardless of the site.
