The prognostic significance of modified frailty index-5 in patients undergoing pneumonectomy for lung cancer.

Objectives: In some centrally located lung cancers, complete excision of the mass cannot be achieved with parenchymal-sparing procedures and pneumonectomy may be required. The mortality and morbidity rates of pneumonectomy were reported to be considerably high. Here, we investigated the effectivity of modified frailty index-5 (MFI-5) in patients undergoing pneumonectomy for non-small cell lung cancer.

Recommendation for Clinical T Staging in Patients with Non-Small Cell Lung Cancer: Volumetric Measurement: A Retrospective Study from Turkey.

Background: Currently, clinical T staging in non-small cell lung cancer (NSCLC) is based on the largest radiological diameter observed on computed tomography (CT). Under this system, tumors with varying shapes-such as spherical, amorphous, or spiculated tumors- can be assigned the same T stage even with different volumes. We aimed to propose a 3-dimensional (3D) volumetric staging system for NSCLC as an alternative to diameter-based T staging and to conduct comparative survival analyses between these methods.

Preliminary outcomes of drainless videothoracoscopic pulmonary wedge resection procedure from Turkey.

Introduction: A chest tube inserted through the intercostal space for air and blood evacuation after thoracic surgery is a serious cause of postoperative pain and prolongs the length of stay. Drainless video-assisted thoracoscopic thoracic surgical procedures, which were previously performed in mediastinal surgical procedures, have also been applied for lung resections in recent years.

Aim: To investigate the superiority of drainless videothoracoscopic pulmonary wedge resection over those with a drain in terms of postoperative pain and length of stay.

Is tumor diameter a risk factor for occult N1 metastasis in patients with peripheral non-small cell lung cancer which is smaller than 3 cm?

The optimum treatment option is surgery for clinical early stage non-small cell lung cancer. Despite all non-invasive and invasive staging effort, occult lymph-node metastasis can be detected in pathological staging. Here, we investigated whether there was any correlation between tumor diameter and occult lymph-node metastasis in N1 stations.

Oxidized Regenerated Cellulose can be a Cause of False Tumor Recurrence on PET/CT in Patients with Lung Cancer Treated Surgically.

Objectives: Regular follow-up of patients with lung cancer treated surgically is crucial to detect local recurrence or distant metastasis of the tumor. Postoperative follow-ups are performed with thorax computed tomography (CT) and, if necessary, positron emission tomography (PET)/CT. Sometimes, inflammatory tissue reactions due to the materials used during the surgery for hemostasis may cause the appearance of tumor recurrence in imaging modalities.

The analysis of pleural complications of COVID-19 pneumonia.

Background/aim: As the number of case reports related to the new type of coronavirus (COVID-19) increases, knowledge of and experience with the virus and its complications also increase. Pleural complications are one relevant issue. We aimed in this study to analyze pleural complications, such as pneumothorax, pneumomediastinum, and empyema, in patients hospitalized with the diagnosis of COVID-19 pneumonia.

Primary pulmonary angiosarcoma presenting as Pancoast tumor.

A primary pulmonary angiosarcoma is an extremely rare entity with fewer than 30 cases reported in the literature. We found no reports of primary pulmonary angiosarcoma presenting as a Pancoast tumor. We describe a case of pulmonary angiosarcoma located in the right superior sulcus that was treated by surgery.
