ABSTRACT
We describe a case of liver metastasis of colorectal cancer that became resectable after bevacizumab (Bmab), CPT-11, and S-1 ie Bmab+IRIS combination chemotherapy. A 65-year-old man experienced repeated constipation and diarrhea in August of 2013. Colonoscopy was conducted by a local doctor, and a tumor(diagnosed as adenocarcinoma tub1 by biopsy)was found in the upper rectum. Computed tomography performed at our institution detected synchronous liver metastasis. On September 9, laparoscopic rectal anterior resection was performed to prevent metastasis to the ileus, and on October 9, the patient began receiving Bmab+IRIS combination chemotherapy. Before chemotherapy, 3 metastases with a maximum diameter of 7 cm diameter)were observed in the right lobe of the liver. After 4 courses of chemotherapy, their maximum diameter was 3 cm, which allowed resection. Ultimately, the metastases were completely resected. Conversion of non optimal resection cases of liver metastases to optimal cases by using Bmab+IRIS chemotherapy is extremely rare. We suggest that Bmab+IRIS chemotherapy could be an option for conversion of non optimal liver resection cases to optimal cases. We report this rare case and discuss the implications of adjuvant chemotherapy for this patient.

The majority of acute cellular rejection occurs in the first few months after liver transplantation. It has been, however, reported that some recipients experience late acute rejection, which occurs more than 3 months after transplantation. We herein report a case of late acute rejection that occurred nearly 10 years after liver transplantation. The patient is a 27-year-old male who underwent a living donor liver transplantation when he was 17 years old. At 9 years 6 months after transplantation, the patient presented with the elevated serum levels of liver enzymes and total bilirubin. A liver biopsy showed acute cellular rejection. Steroid bolus therapy was not effective, but we successfully used deoxyspergualin as a rescue therapy. Late acute cellular rejection that occurs nearly 10 years after transplantation has so far been rarely reported. It is generally believed that late acute rejection may be more resistant to treatment and be associated with a higher rate of graft loss, as well being associated with the development of chronic ductopenic rejection. In this report, we have shown that deoxyspergualin is safe and effective for treatment of steroid-resistant late acute rejection, preventing from graft loss of chronic rejection.
