[A Case of Advanced Rectal Cancer in Which Long-Term Disease-Free Survival Was Achieved by Multidisciplinary Therapy]

The is a case involving a 55-year-old man with advanced rectal cancer(type 3). MRI showed urinary tract and regional lymph node metastases without distant metastasis. The tumor was reduced(PR)after neoadjuvant chemotherapy(mFOL FOX6 plus Bmab, 4 courses). The patient underwent an abdominoperineal resection. Because infiltration of the tumor into the lower urinary tract was deep, it was also resected and repaired. The clip was placed to mark the repaired region. Pathological examination revealed that excision stump at the anterior wall of the urethra was cancer positive without lymph node metastasis. He was then administered chemotherapy(mFOLFOX6 4 courses)and irradiated 60 Gy in both sides of the inguinal lymph node to prevent metastasis to the pelvicdomain. One year and 6 months postoperatively, as the left inguinal lymph node swelled at 3.7 cm irregularly, he further received chemotherapy(FOLFIRI 8 courses). The size of the lymph node became normal with a good response to FOLFIRI. Six years postoperatively, he remains alive and well with no evidence of recurrence.
