[A case of stage IVb vulvar cancer effectively treated by concurrent chemoradiotherapy with cisplatin].

A 72-year-old woman was hospitalized because of a 10 cm tumor in her right inguinal area. Furthermore, a 6 cm tumor mass was observed in her right vulva. Computed tomography revealed multiple swollen lymph nodes in the para-aortic and pelvic areas. On the basis of these findings, the patient was diagnosed with stage IVb squamous cell carcinoma of the vulva. Radiation therapy of 67.4 Gy/33 Fr was administered to the pelvis, inguinal area and vulva. Four courses of chemotherapy with cisplatin (40 mg/m(2)) were concurrently administered every week during radiation therapy. The response to chemoradiotherapy was assessed to be complete. The patient has been doing well without any recurrence for 24 months.
