Outcomes and pathologic response of primary lung cancer treated with tyrosine kinase inhibitor/immune checkpoint inhibitor before salvage surgery.

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.

Unusual giant multilocular thymic cyst with mature teratoma including a carcinoid component in the mediastinum.

Background: Teratoma is the second most common mediastinal neoplasm, but malignant transformation in mature teratomas is uncommon, and cases of carcinoid tumor with teratoma are described in only a few studies. In addition, multilocular thymic cyst associated with mature mediastinal teratoma is also a rare entity. There have been no reports of case with the coexistence of these three pathological lesions.

Superior vena cava replacement combined with venovenous shunt for thymic carcinoma.

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.

Two extremely rare cases of extrapleural hematoma.

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.
