[A case successfully treated with total pelvic exenteration after preoperative chemotherapy FOLFOX4 plus bevacizumab for unresectable sigmoid colon cancer with extramural progression].

The patient was a 73-year-old woman. Her chief complaints were abdominal pain and lower abdominal distension. After some examinations, we diagnosed pelvic tumor, bladder cancer (adenocarcinoma) and sigmoid colon cancer. We performed a first operation, but the pelvic tumor was firmly fixed anterior to the sacrum and right common pelvic artery. We judged it unresectable and performed tumor biopsy and ileostomy. The pathological findings were very similar to sigmoid colon cancer, so we diagnosed that the pelvic tumor was sigmoid colon cancer with extramural progression. Later, the patient was treated with three courses of FOLFOX4 and three courses of bevacizumab+FOLFOX4. After this chemotherapy, the pelvic tumor was reduced significantly, we considered resection possible and performed pelvic exenteration. She has had no recurrence for 6 months after second operation. This treatment appeared to be effective for unresectable primary colon cancer.

[Papillary adenocarcinoma in a seminal vesicle cyst associated with contralateral renal agenesis: a case report].

We report a case of papillary adenocarcinoma inside a seminal vesicle cyst associated with contralateral renal agenesis in a 30-year-old man. Coexistence of a seminal vesicle cyst and tumors is rare. Surgical excision was performed but he died due to liver metastases one year later.
