[A Case of Squamous Cell Carcinoma of the Anal Canal with a Perianal Abscess].

A 72-year-old female patient was referred to our department because she felt pain at the anus with pus discharge. Physical examination revealed a tumor on the left side of the anus, and a subcutaneous induration near the tumor. Abdominal CT scan revealed an irregularly shaped tumor with abscess formation.

[A Case of Brain Metastasis from Rectal Cancer with Synchronous Liver and Lung Metastases after Multimodality Treatment--A Case Report].

We report a case of brain metastasis from rectal cancer a long time after the initial resection. A 62-year-old woman, diagnosed with lower rectal cancer with multiple synchronous liver and lung metastases, underwent abdominoperineal resection after preoperative radiochemotherapy (40 Gy at the pelvis, using the de Gramont regimen FL therapy: 1 kur). The histological diagnosis was a moderately differentiated adenocarcinoma.

Effect of tumor deposits on overall survival in colorectal cancer patients with regional lymph node metastases.

Objectives: The staging system of the International Union Against Cancer considers tumor deposits to be N1c in patients with no regional lymph node metastasis, but the significance of tumor deposits in patients with regional lymph node metastases is unclear. We investigated the effect of tumor deposits on overall survival in colorectal cancer patients with regional lymph node metastases.

Patients And Methods: From 2000 to 2008, 551 patients underwent resections for colorectal cancer at our medical center.
