Abstract:
Urachal cancer is a rare form of bladder cancer that arises from the urachus, a vestigial musculofibrous band that extends from the dome of the bladder to the umbilicus. Urachal cancer often presents at an advanced stage and has a dismal prognosis. We present a case of a young woman with urachal cancer that recurred rapidly post-partial cystectomy. The patient was treated with up to 6 different chemotherapy regimens, including an oral antiangiogenic drug as part of a clinical trial. Our case illustrates the aggressive nature of this disease, the difficulty in accessing drugs for the treatment of rare cancers and the lack of late stage clinical trials to help guide therapeutic decisions.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
Combination Therapies and Personalized Medicine
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
