Serum vitamin D levels in patients with lung metastases.

Background And Aim: Vitamin D deficiency is linked to increased cancer risk and death but the effect of vitamin D substitution on the prognosis of patients with malignant disease is debatable. We aimed to investigate the value of serum vitamin D3 levels in patients with a history of malignancy and confirmed lung metastases.

Materials And Method: Serum Vitamin D2 (25-hydroxyergokalciferol) and D3 (25‑hydroxycholekalciferol) levels were measured in 38 patients (28 with and 10 without lung metastases) using high performance liquid chromatography (HPLC).

Precise Localization of the Subsolid Lesion by Colour Marking under CT-Guided Control before Video-Assisted Surgery Resection: A Case Report.

Introduction: Lung cancer is one of the leading causes of death worldwide. Lung lesions, often discovered incidentally on chest CT, pose a diagnostic challenge due to their diverse etiology, including both benign and malignant nature. A key step in the assessment of these lesions is the evaluation of their morphological features in the CT image, size, and behavior over time.

Subpleural pulmonary nodule marking with patent blue V dye prior to surgical resection.

Background And Objective: Subpleural located pulmonary nodules are perioperatively invisible to the surgeon. Their precise identification is conventionally possible by palpation, but often at the cost of performing a thoracotomy. The aim of the study was to evaluate the success rate and feasibility of the pre-operative CT-guided marking subpleural localized nodule using a mixture of Patent Blue V and an iodine contrast agent prior to the extra-anatomical video-assisted thoracoscopic surgery (VATS) resection in patients for whom the primary anatomical resection in terms of segmentectomy or lobectomy was not indicated.
