A comparative study of survival outcomes between partial and radical cystectomy in octogenarians with muscle-invasive bladder cancer.

Background: Neoadjuvant chemotherapy with radical cystectomy (RC) is the preferred first-line treatment for localized muscle-invasive bladder cancer (MIBC). Due to the concern about morbidity associated with RC, the elderly population considers bladder preservation alternatives. Guidelines suggest partial cystectomy (PC) can be considered a viable option in carefully selected individuals.

Routine elastin staining improves venous invasion detection in colorectal carcinoma.

Background: Colorectal carcinoma is the second most common cause of cancer-related deaths in North America. Invasion of tumor cells into lymphatic and blood vessels is an imperative step in the metastatic progression of colorectal carcinoma.

Objectives: This is a before-and-after study conducted by the Department of Pathology and Laboratory Medicine of Mount Sinai Medical Center of Florida to assess the impact on venous invasion (VI) detection by implementing routine elastin staining on all tumor-containing blocks per case, where feasible, in colorectal carcinoma (CRC) resection specimens.
