Advanced primary nonurachal adenocarcinoma of urinary bladder responding to modified FOLFOX6 and capecitabine: a case report.

Careful morphology and immunohistochemistry study can make an accurate differential diagnosis of primary adenocarcinoma of urinary bladder from metastatic lesions involving bladder, especially cancer arising in colon, but there is yet no consensus regarding the standard chemotherapy for advanced adenocarcinoma of urinary bladder among medical oncologists. Sustained response to modified FOLFOX6 (fluorouracil, oxaliplatin plus leucovorin) regimen and oral capecitabine for multiple metastases in a patient with primary nonurachal adenocarcinoma of urinary bladder is presented here as a strong support that the frontline chemotherapy for this infrequent malignant disease is just like what could be chosen for colorectal cancer.
