[A Case of Pathological Complete Response of Advanced Rectal Cancer with Direct Invasion of the Prostate and Extra-Regional Lymph Node Metastasis after Chemotherapy].

A 62-year-old man was diagnosed as having advanced rectal cancer with an invasive carcinoma of the prostate and the right inguinal lymph node metastasis. He received chemotherapy consisting of combination of 5-FU, oxaliplatin, Leucovorin (mFOLFOX6)and bevacizumab. After 5 courses of the chemotherapy, CT and MRI findings revealed the tumor shrinkage. After 6 courses of the chemotherapy, a laparoscopic abdominoperineal resection, bilateral lymph node dissection and a resection of right inguinal lymph node were performed. The pathological findings showed a pCR. NAC with mFOLFOX6 and bevacizumab may contribute to the reduction of the surgical stress for the patients and be an effective treatment for advanced rectal cancer with distant lymph node metastasis.
