Factors that influence survival in unresectable metastatic or locally advanced colorectal cancer.

Purpose: Half of patients with colorectal cancer (CRC) have metastasis during the whole course of the disease. Fewer than 10% of those are still alive at 5 years. Locally advanced CRC accounts for 7% to 33% of CRC relapses.

Acute rectocolitis following endoscopy in health check-up patients--glutaraldehyde colitis or ischemic colitis?

Purpose: Acute rectocolitis is a rare complication that follows endoscopy. It could be caused by glutaraldehyde or ischemic injury. The clinical, endoscopic, radiological, and pathological features of glutaraldehyde-induced colitis may mimic those of ischemic colitis.

Shifting to first-line regimen after previous failure of irinotecan and oxaliplatin containing chemotherapies in unresectable metastatic colorectal cancer: a retrospective study of case analysis.

Purpose: Conventional use of FOLFIRI-FOLFOX or the reverse sequence is the optional regimen in metastatic unresectable colorectal cancer (CRC). We present our experience in chemotherapy (C/T) shifting to first-line regimen after previous failure of irinotecan and oxaliplatin containing regimens.

Materials And Methods: A total of 48 patients with metastatic unresectable CRC were examined retrospectively.

Factors that influence 12 or more harvested lymph nodes in early-stage colorectal cancer.

Background: The number of lymph nodes required for accurate staging is a critical component in early-stage (stage A and B) colorectal cancer (CRC). Current guidelines demand at least 12 lymph nodes to be retrieved. Results of previous studies were contradictory in factors, which influenced the number of harvested lymph nodes.

Primary lymphoma of the penis.

Primary penile lymphoma is a rare neoplasm. We report a case of this unusual clinical manifestation. A 70-year-old male presented with a painless penile mass for 6 months.
