Perioperative circulating tumor cells in surgical patients with non-small cell lung cancer: does surgical manipulation dislodge cancer cells thus allowing them to pass into the peripheral blood?

Purpose: We herein evaluated the status of circulating tumor cells (CTC) dislodged from the tumor during surgery in patients who underwent pulmonary resection for non-small cell lung cancer (NSCLC) to assess the clinical implications.

Methods: Tumor cells in the peripheral arterial blood before surgery (Before) and immediately after lung resection (After) and in the blood from the pulmonary vein of the resected lung were detected using a size selective method. The clinicopathological characteristics and the prognosis were then analyzed according to the CTC status: no tumor cells detected (N), single tumor cell or total number less than 4 cells (S), and existence of clustered cells (C).

[Additional Lobectomy after Pulmonary Excision for Non-invasive Lung Adenocarcinoma due to Malignant Positive Cytology at the Residual Lube].

A 67-year-old male was pointed out a pure ground grass opacity sized 1.7 cm in computed tomography (CT), which reminded unchanged size in CT findings for 18 months. This region was removed using pulmonary wedge resection with margin length of 0.

[Hyponatremia caused by pituitary metastasis of lung cancer].

A 57-year-old man was admitted with headache, vomiting, and bloody sputum. We diagnosed large cell lung cancer T4N2M1 (pituitary metastasis), Stage IV. When hospitalized, low values of cortisol and hyponatremia were found.

[Pneumatosis cystoides intestinalis in a patient with lung cancer].

We report a case of pneumatosis cystoides intestinalis (PCI) in a patient with lung cancer. A 60-year-old woman was admitted with multiple lung tumors and multiple brain tumors. She was given steroid hormones to reduce her brain edema.
