Ferritin to Transferrin Ratio: a new prognostic factor for renal cell carcinoma.

Objectives: To assess the prognostic value of the preoperative serum ferritin-to-transferrin ratio (FTR) in renal cell carcinoma (RCC). Methods：We retrospectively reviewed data from 226 patients who underwent surgery for non-metastatic RCC at our institution between January 1, 2012, and June 30, 2021. Time-dependent receiver operating characteristic (timeROC) analysis identified the optimal FTR cut-off, dividing patients into high and low FTR groups.

Diagnostic accuracy of folate receptor-positive circulating tumor cells in differentiating between benign and malignant pulmonary nodules.

Background: Currently, traditional blood biomarkers such as neuron-specific enolase (NSE), carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA) etc. are mostly elevated in the late stage of tumour, and patients have already lost the chance of tumour eradication when the relevant indexes are found to be elevated. Therefore, there is a need for blood biomarkers with higher sensitivity, better specificity, and better accessibility.

Laparoscopic specimen extraction in vitro: preliminary experience.

Background: The last procedure performed by the surgeon in laparoscopic surgery is to extract the specimen through the smallest incision possible. This experiment aimed to explore the maximum diameter of specimens that can be extracted through auxiliary incisions of different lengths and shapes by in vitro physical experiments.

Materials And Methods: We used the abdominal wall with the muscle layer, fixed on a square wooden frame, to simulate the human abdominal wall.

18F-FDG PET/CT features of ureteral metastases from breast cancer: a case report.

Breast cancer metastasis to the ureter is rare. Fluorine-18-fluorodeoxyglucose positron emission tomography (18F-FDG PET)/computed tomography (CT) is widely used to identify primary lesions of metastatic tumours, however, 18F-FDG PET/CT imaging features of ureteral metastasis from breast cancer are rarely reported. Herein, the case of a 46-year-old woman with recurrent left flank pain for 5 months, who was admitted to the Cancer Hospital of Guangxi Medical University and Guangxi Cancer Research Institute, is described.

Unilateral T-shaped incomplete duplex nephrectomy in an adolescent under laparoscopy: A case report.

Introduction: Duplicate kidneys are the most common congenital abnormality of the urinary system. The location of duplicate kidneys varies. We report a case of an adolescent with upper and lower kidneys that are arranged vertically and approximately T-shaped.
