Fully automated segmentation and classification of renal tumors on CT scans via machine learning.
BMC Cancer

Department of Urology, Seoul National University Hospital, 101 Daehak-ro, Jongno-gu, Seoul, 03080, South Korea.
Background: To develop and test the performance of a fully automated system for classifying renal tumor subtypes via deep machine learning for automated segmentation and classification.
Materials And Methods: The model was developed using computed tomography (CT) images of pathologically proven renal tumors collected from a prospective cohort at a medical center between March 2016 and December 2020. A total of 561 renal tumors were included: 233 clear cell renal cell carcinomas (RCCs), 82 papillary RCCs, 74 chromophobe RCCs, and 172 angiomyolipomas.

Renal cell carcinoma (RCC) is a heterogeneous disease that represents the most common type of kidney cancer. The classification of RCC is primarily based on distinct morphological and molecular characteristics, with two broad categories: clear cell RCC (ccRCC) and non-clear cell RCC (nccRCC). Clear cell RCC is the predominant subtype, representing about 70-80% of all RCC cases, while non-clear cell subtypes collectively make up the remaining 20-30%.

In this article, we aim to demonstrate that thyroid carcinoma can metastasize to the small bowel. This case report involves a 66-year-old woman who underwent total thyroidectomy surgery in 2019, with histopathology revealing a 3A undifferentiated thyroid cancer. She presented with symptoms of bowel obstruction, including abdominal pain, nausea, and vomiting.

Department of Urology, The First Affiliated Hospital of Xiamen University, School of Medicine, Xiamen University, 55 Zhenhai Road, Xiamen, 361003, Fujian Province, China.
In renal cell carcinoma (RCC) patients with inferior vena cava (IVC) tumor thrombus, neoadjuvant therapy could alleviate the burden of tumor thrombus, enhance the safety and feasibility of surgical resection, and improve patient prognosis. The combination of tislelizumab and axitinib has demonstrated efficacy in the treatment of advanced RCC. Our study aimed to evaluate the efficacy and safety in the neoadjuvant therapy setting of tislelizumab and axitinib in RCC patients with IVC tumor thrombus.

Stanford Medical Center; Stanford, CA, United States of America.
Gamna-Gandy (GG) bodies are sclerosiderotic nodules composed of iron pigment and calcium, that have been described predominantly in the spleens of patients with sickle cell disease. Their formal depiction in the kidney is mainly limited to case reports and small series. We aimed to investigate the incidence of GG bodies and associated clinicopathologic features in consecutive nephrectomies performed for renal tumors.
