Clinical Differences in Postoperative Atrial Fibrillation After Open Thoracic Surgery

Manabu Kashiwagi, Kentaro Honda, Keiji Hayata, Yoshimitsu Hirai et autres

Background New-onset atrial fibrillation (AF) occurring after surgery is called postoperative atrial fibrillation (POAF). Whether its clinical impact differs according to the type of thoracic surgery is unclear, so we investigated the differences of POAF after thoracic aortic (AS), esophageal (ES), and …

Case Report: Fatal osimertinib-related interstitial lung disease during adjuvant therapy after left pneumonectomy in a patient with lung adenocarcinoma undergoing maintenance hemodialysis

Takahiro Kaki, Yuhei Harutani, Yoshimitsu Hirai, Hideto Iguchi et autres

Osimertinib is recommended not only for advanced EGFR-mutated non-small cell lung cancer (NSCLC) but also as adjuvant therapy after complete resection, leading to increasing opportunities for its clinical use. However, interstitial lung disease (ILD) is a serious adverse event, and its incidence …

Intra‐Tumoral Alveolar Remnants as a Prognostic Factor in Small Peripheral Lung Squamous Cell Carcinoma

Hideto Iguchi, Yurina Mikasa, Ibu Matsuzaki, Fidele Yambayamba Musangile et autres

Limited resection has recently emerged as a standard procedure for small peripheral squamous cell carcinoma (SqCC) of the lung, emphasizing the need for accurate prognostic prediction. We retrospectively analyzed 53 peripheral SqCCs at pathological stage IA. Hematoxylin and eosin (H&E)-stained and immunohistochemically …

Immediate Breast Reconstruction Using an Expanded Latissimus Dorsal Musculocutaneous Flap Without Body Position Change

Miwako Miyasaka, Megumi Kiyoi, Aya Shima, Yoshimitsu Hirai et autres

Background: Breast reconstruction using expanded latissimus dorsal musculocutaneous flap (eLDMC flap) is known for excellent outcome; however, intraoperative change in body position to assess cosmesis prolongs operative time. Here, we present the results and the strengths of immediate breast reconstruction with an …

Mycophenolate Mofetil for Steroid-Refractory Immune-Related Hepatitis and Sclerosing Cholangitis Following Neoadjuvant Chemoimmunotherapy in Non-Small Cell Lung Cancer: A Case Report

Hideto Iguchi, Takahiro Kaki, Yuhei Harutani, Daiki Kitahara et autres

INTRODUCTION: Neoadjuvant chemoimmunotherapy is increasingly regarded as the standard treatment for resectable non-small cell lung cancer. Although it improves survival outcomes, immune-related adverse events can delay or prevent curative surgery. Optimal strategies for managing these adverse events in the preoperative setting remain …

Can FDG ‐ PET after neoadjuvant chemotherapy plus nivolumab predict residual disease in non‐small cell lung cancer?

Hideto Iguchi, Hiroaki Akamatsu, Yoshimitsu Hirai, Takahito Nakaya et autres

Neoadjuvant therapy with nivolumab improves event-free survival (EFS) in patients with resectable non-small cell lung cancer, and a pathological complete response is a predictor of longer EFS. We assessed metabolic responses using 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) before and after neoadjuvant treatment to …

Rosai–Dorfman disease differentiated from a posterior mediastinal tumour: a case report

Yoshimitsu Hirai, Yuichi Takahashi, Takahiro Kaki, Aya Shima et autres

Rosai-Dorfman disease presenting solely with intrathoracic lesions is exceptionally rare. Herein, we report the case of a 53-year-old man presenting with a posterior mediastinal tumour. Computed tomography revealed a 7-cm soft tissue shadow in the posterior mediastinum. Positron emission tomography-computed tomography demonstrated …

Neoadjuvant nivolumab plus chemotherapy followed by resection for superior sulcus tumour with high PD‐L1 expression: A case report

Takahito Nakaya, Yoshimitsu Hirai, Hiroaki Akamatsu, Fumiyoshi Kojima et autres

The standard treatment for resectable non-small cell lung cancer (NSCLC) located in the superior sulcus is neoadjuvant chemoradiotherapy followed by highly invasive resection. Based on the results of the CheckMate 816 trial, which showed a marked improvement in the efficacy of neoadjuvant …
