Prospective study of once-daily accelerated partial breast irradiation using 3-dimensional conformal external beam radiotherapy for Japanese women: 12-year outcomes, toxicity, and cosmesis.

Background: To analyze in a prospective study the long-term safety and efficacy of 3-dimensional conformal radiotherapy (3D-CRT) to deliver accelerated partial breast irradiation (APBI) for Japanese women with early breast cancer.

Methods: Breast cancer patients with pathological tumor size ≤ 3 cm, age ≥ 20 years, lumpectomy with at least a 5 mm margin, and ≤ 3 positive axillary nodes were eligible. APBI was delivered by 3D-CRT at a dose of 38.

Initial results of uniportal and robot-assisted subxiphoid thymectomy.

Background: We previously reported on subxiphoid uniportal thymectomy (SUT) and subxiphoid robotic thymectomy (SRT). This descriptive study aimed to evaluate the feasibility and safety of both SUT and SRT techniques.

Methods: Between March 2011 and December 2022, 268 patients underwent subxiphoid thymectomy.

First case of major lung resection using the hinotori™ surgical robot system.

We performed the first case of major lung resection using the hinotori™ surgical robot system, which is a new surgical support robot system developed in Japan. A left lower lobectomy and subcarinal lymph node dissection were performed. The operation time was 3 h and 5 min, the cockpit time (console time) was 2 h and 5 min, and the blood loss was 40 g.

Intereye comparison of visual field progression in eyes with open-angle glaucoma.

Purpose: To investigate the intereye correlations between and differences in the rates of visual field (VF) progression in eyes with bilateral open-angle glaucoma.

Study Design: Retrospective, longitudinal, observational study.

Methods: Patients with bilateral open-angle glaucoma with 8 or more reliable 30 - 2 standard automated perimetry tests over a period of more than 2 years were enrolled.
