Detecting tumor-infiltrating Forkhead box P3-positive T cells in the prognosis of lung adenocarcinoma: Possible role of clustering tumor interleukin-12 subunit alpha and transforming growth factor beta 1 expression.

Background: While regulatory T cells (Tregs) are a poor prognostic factor for lung cancer, they may be detected as Forkhead box P3+ (FOXP3+) and cluster of differentiation (-CD) 4+ T cells by classifying FOXP3+CD4+ T cells into different subpopulations of CD4 cells.

Objectives: To classify clusters of tumor-infiltrating Tregs in lung adenocarcinoma based on the mRNA expression levels of interleukin-12 subunit alpha (IL12A) and transforming growth factor beta 1 (TGFB1) in tumor specimens.

Material And Methods: Seventy-nine patients with lung adenocarcinoma were evaluated in this study.

Efficacy of measuring the invasive diameter of lung adenocarcinoma using mediastinal window settings: A retrospective study.

The recently published 8th edition of the tumor node and metastasis Classification of Lung Cancer proposes using the maximum dimension of the solid component of a ground glass nodule (GGN) for the T categorization. However, few studies have investigated the collection of this information when using mediastinal window settings. In this study, we evaluated tumor measurement data obtained from computed tomography (CT) scans when using mediastinal window settings.

Ciliated muconodular papillary tumor of the lung presenting with polymyalgia rheumatica-like symptoms: a case report.

Ciliated muconodular papillary tumors (CMPTs) of the lung have been recently characterized as low-grade malignant tumors and may be indistinguishable from adenocarcinoma (AIS) because they are both abundant in mucous and spread along the alveolar walls. Herein, we report a case of CMPT with polymyalgia rheumatica (PMR)-like symptoms, which resolved after resection. After the surgery, antinuclear antibody tests were performed, but no abnormalities were noted.

[Thyroid Transcription Factor-1 is Useful for Identifying Primary Tumors].

A 67-year-old man had underwent liver resection 3 years previously. The pathological diagnosis was intrahepatic cholangiocarcinoma. However, a follow-up computed tomography(CT) scan revealed gradual enlargement of the pulmonary nodule left S1+2 and he was performed surgery.

Spontaneous regression of a carcinoid tumor that required resection owing to its reappearance and subsequent enlargement after 2 years: a case report.

We present a rare case of spontaneous regression in a typical lung carcinoid. A 20-year-old woman with an abnormal shadow on a chest radiograph was admitted to our hospital. Computed tomography revealed a smooth nodule in the left S1 + 2 segment.

Mesothelial cyst derived from chest wall pleura growing after thoracic surgery: a case report.

Background: Intrathoracic mesothelial cysts almost always arise in the mediastinum, and extramediastinal mesothelial cysts are extremely rare. Here we describe a case of mesothelial cyst derived from the chest wall pleura growing after thoracic surgery.

Case Presentation: A 63-year-old Japanese woman was referred to our department.

Mediastinal mature teratoma perforating the right lung that was successfully resected with complete thoracoscopic surgery: A case report.

Introduction: A perforating mediastinal mature teratoma can cause severe inflammation and adhesion; therefore, open surgery is usually performed. Asymptomatic perforation involving a teratoma is very rare. Complete thoracoscopic surgery is often difficult because of inflammation associated with perforation and the frequently large size of a mediastinal mature teratoma.

Intractable pneumothorax complicated with interstitial pneumonitis treated with the Tachosuture technique: A case report.

It has been proven that the Tachosuture technique is effective for preventing prolonged air leaks caused by pulmonary resection. We successfully used the Tachosuture technique to treat intractable pneumothorax with interstitial pneumonia. This technique avoids pulmonary resection and contributes to acute exacerbations of interstitial pneumonia.

Video-assisted thoracoscopic surgery can help enable the complete resection of a mediastinal tumor caused by immunoglobulin G4-related disease and avoid the need for postoperative medication: A case report.

Immunoglobulin (Ig) G4-related disease has various clinical signs and symptoms, and steroidal therapy with corticosteroids has been found to be effective for treatment. Few cases of IgG4-related disease associated with paravertebral tumor have been reported, and there have been no reports on complete resection of such a tumor. Here, we report a case of IgG4-related disease associated with a paravertebral tumor that was successfully resected without the need for postoperative medication.

Remitting seronegative symmetrical synovitis with pitting edema syndrome complicated with primary lung cancer.

Remitting seronegative symmetrical synovitis with pitting edema syndrome has been reported to be associated with malignant tumors. However, few cases occurring with lung cancer have been reported. We here report a case of remitting seronegative symmetrical synovitis with pitting edema syndrome complicated with lung cancer.

[Thoracoscopic diaphragmatic plication for eventration of diaphragm in children using no-knife automatic suturing device].

Unlabelled: Diaphragm eventration could inhibit the lung development due to compression. Thus diaphragm plication is required for the diaphragm eventration to prevent lung compression causing lung immaturity. However, we sometimes encounter the difficulty in endoscopic plication for fragile diaphragm without damaging it in narrow thoracic space in children.

Successful thoracoscopic removal of a giant teratoma following extraction of cystic conponents: a case report.

Video-assisted thoracoscopic surgery is a type of minimal-access surgery. The nature of the surgery means that there are limitations on the size of a tumor that can be removed through an access incision. Herein, we report our experience removing a giant teratoma (16 × 14 × 13 cm in size) from the anterior mediastinum of a young girl.
