A 65-year-old man was admitted for a tissue biopsy of suspected right middle and lower lobe lung cancer with multiple bone metastases. During hospitalization, he started to cough up blood, which recurred after intubation. The patient experienced asphyxia, which led to cardiopulmonary arrest, but was successfully resuscitated.

Objectives: The MARS2 trial questioned the efficacy of curative intent surgery for pleural mesothelioma, while real-world clinical data from Japan suggest a favourable prognosis in surgical cases, indicating survival benefits in selected patients. The newly revised 9th edition of the tumour-node-metastasis classification introduces a novel indicator based on pleural thickness.

Methods: We conducted a retrospective evaluation of patients with pleural mesothelioma who underwent pleurectomy decortication between 2012 and 2022.

Background: Durvalumab after chemoradiation (PACIFIC regimen) provides favorable treatment outcomes for unresectable stage III non-small cell lung cancer (NSCLC). The feasibility of salvage surgery after the PACIFIC regimen has been reported in some studies; however, its efficacy remains unclear. We herein present the first case of salvage surgery after the PACIFIC regimen for a superior sulcus tumor with N3 involvement, in which a pathological complete response was achieved.

Background: Curative intent surgery may be indicated for some patients with resectable early stage malignant pleural mesothelioma (MPM). However, sarcomatoid MPM is a highly aggressive subtype for which curative intent surgery is generally not recommended.

Case Presentation: We present the case of a 63-year-old man who presented with dyspnea and chest tightness.

Purpose: Advances in primary lung cancer drug therapy have extended patients' survival, including patients with stage IV disease. This study assessed the safety and effectiveness of salvage surgery following tyrosine kinase inhibitor (TKI) or immune checkpoint inhibitor (ICI) therapy in primary lung cancer.

Methods: A retrospective chart review was conducted of 2050 primary lung cancer surgeries performed at our institution between 2012 and 2022.

Salvage surgery following immunotherapy is a promising treatment option for advanced malignant tumour. However, only a few cases of salvage surgery for malignant pleural mesothelioma (MPM) have been reported. This retrospective study was conducted to assess the feasibility of salvage surgery following immunotherapy for initially unresectabele MPM.

Background: Approximately 15-29.6% of patients with thymoma have myasthenia gravis (MG). Some of these patients develop MG after thymectomy despite having no history of MG or related symptoms.

Introduction: Advanced-stage thymic malignancies are a heterogeneous group of mediastinal tumors that include thymoma and thymic carcinoma infiltrating the surrounding thoracic structures. When the tumor infiltrates the superior vena cava (SVC), radical resection can be selectively achieved via en bloc SVC resection and its prosthetic conduit replacement. We herein report a case of SVC replacement for thymic carcinoma en bloc radical resection.

Choosing an optimal procedure to stabilize the chest wall for multiple rib fractures can be challenging for surgeons. Stabilization with rib plates or intramedullary devices requires exposure of fractured bones, whereas chest stabilization with intercostal -suture and mesh does not, yet it offers the chest wall a sufficient level of stability. Here, we report a case of a flail chest due to multiple rib fractures for which a simple chest wall fixation using intercostal -suture and mesh was efficient.

Introduction: Superior sulcus tumors (SSTs) are a wide range of tumors invading a section of the apical chest wall called the thoracic inlet. The unique characteristics of SSTs lie in the anatomy of the region where these tumors occur. For this reason, a surgical approach to treating these tumors is technically demanding, and complete resection may be difficult to accomplish.

Background: Extrapleural hematoma is uncommon. However, according to the size of hematoma and/or the progression of anemia, surgical treatment to control bleeding might be necessary because a huge hematoma can cause ventilator and circulatory disturbances to press heart and lung. We present two unusual cases of huge extrapleural hematoma in an anticoagulated patient with no apparent history of trauma or otherwise traumatic episodes.

This report describes the case of a 67-year-old male with inflammatory breast cancer. He had noticed a left breast mass about seven years previously, but he had ignored it. He then visited our hospital 4 months previously when multiple small masses occurred in the left front chest wall.

Background: Fenestration is performed in patients with bronchopleural fistula to avoid a life-threatening situation. However, usually, this procedure is required 9-cm mean length of the incision with rib resection.

Case Presentation: A 73-year-old man underwent right lower lobectomy with lymph node dissection (ND2a-2) for primary lung cancer (cT1cN2M0 Stage IIIA) with combined pulmonary fibrosis and emphysema.
