[A Case of Advanced Rectal Cancer with Synchronous Pulmonary Metastasis Undergoing Laparoscopic Curative Resection after Chemotherapy].

The patient was a 50-year-old man who complained of bloody stool and proctal discomfort. After hospitalization, he was diagnosed bearing advanced lower rectal cancer with lateral lymph nodes and bilateral pulmonary metastases(cT3N3M1a, Stage IV ). He was treated with irinotecan, Leucovorin and 5-fluorouracil(FOLFIRI)plus cetuximab because of RAS wild type. After 11 courses of the chemotherapy, all pulmonary metastases were disappeared(CR). Six months after the initialtreatment, laparoscopic abdominoperineal resection with lateral lymph node resection was performed with curative intent. After the operation, additional1 2 courses of the same chemotherapy were carried out. One year after operation, there is no sign of recurrence. Though used to be considered non-curative, advanced rectal cancer with distant metastases could be potentially cured by multidisciplinary treatments.
