[Surgical Treatment for Extremely Elderly Patients over 90 Years of Age with Stage IV Colorectal Cancer - A Report of Four Cases].

: We report 4 cases ofStage IV colorectal cancer patients over 90 years ofage who received surgical treatment. All of 4 cases were right-sided advanced colon cancer(1 case had also recto-sigmoid advanced cancer)and were received emergency operation. Two cases received resection ofprimary tumors and anastomosis, the other 2 cases received only ileostomy or colostomy. Three cases were able to be discharged from hospital successfully, but unfortunately, we lost one case because of cerebrovascular complication after surgery. We could provide palliative care facilities or home care services for survived three cases after spending certain time with their families peacefully. We treated them successfully with a collaborative medical team including experienced staffs for oral care, skin care, rehabilitation, mental care and social workers and others. Regarding to surgical treatment ofStage IV colorectal cancer patient, especially for extremely elderly patients over 90 years of age, we should consider not only perioperative treatment but also post- discharge comprehensive and palliative care.
