[Preoperative chemoradiation (XELOX/RT) therapy for anal canal adenocarcinoma with the metastasis to inguinal lymph node].

For a woman with poorly-differentiated anal canal adenocarcinoma in acknowledgment of metastasis to right inguinal lymph node, we gave radiotherapy combined with capecitabine as chemotherapy. Then the next two months, we performed XELOX therapy. Subsequently, we performed laparoscopic rectal amputation+D1 dissection+right groin lymph node dissection. The effect of preoperative chemoradiotherapy and pathological examination of the main tumor was Grade 2. And the right inguinal lymph node showed only a mucous persistence. Capecitabine was given as an adjuvant postoperative treatment and did not show a recurrence for five months after the operation. For a treatment for anal canal adenocarcinoma in acknowledgment of metastasis to inguinal lymph node, preoperative chemoradiotherapy may be effective.
