Twenty patients( 30 nodules) with metastatic liver cancer( MLC) and 10 cases with hepatocellular carcinoma( HCC) treated by stereotactic radiotherapy (SRT) were analyzed. SRT was administered at 48.0 or 52.8 Gy/4 Fr/1 wk. The response rate (RR) in MLC patients was 78%, and 11 patients survived longer than 1 year and 9 patients survived as long as 2 years. Clinical analysis suggests that the ideal indications for SRT in MLC are solitary nodules in patients without extrahepatic disease who have undergone systemic chemotherapy. Although RR of SRT for HCC was as high as 85%, intrahepatic recurrence was observed in all patients and 6 patients died within 1 year. Further analysis is needed to determine the indication for SRT in HCC patients. Source

We report a case of recurrent gastric cancer that was effectively controlled with radiation therapy. A 63-year-old man underwent total gastrectomy, cholecystectomy and D2 dissection in February 2006 for early gastric cancer in the upper third area that was diagnosed with papillary adenocarcinoma and Stage IA (T1 (SM), N0, H0, P0, CY0, M0). He underwent lateral segmentectomy of the liver for liver metastasis of S2/3. He suffered from No. 12 lymph node(LN)metastasis in February 2009, so CPT-11, next to S-1, was administered. Portal tumor thrombosis (PTT) and liver S8 metastasis were observed in September 2009. First, chemoradiotherapy (CRT) ( S-1 80 mg/body+total of 65 Gy per 26 Fr) for #12 LN and PTT was performed and, in turn, stereotactic radiation therapy (SRT: total of 52.8 Gy per 4 Fr) was performed. A complete response in all of tumors was noted and he was presently alive with no sign of recurrence after 19 months after CRT and SRT. Grade 3 or 4 adverse events were not recognized. It is thought that radiation therapy is one of effective treatments for localized metastasis from gastric cancer. Source

A 63-year-old male admitted for hematemesis was diagnosed with type 3 advanced gastric cancer located in the upper and middle body of the stomach in an endoscopic examination. Abdominal computed tomography demonstrated lymph nodes metastasis and a splenic vein thrombus. Since curative resection was not deemed possible, we performed neoadjuvant chemotherapy using S-1 (120 mg, day 1-21) plus CPT-11 (135 mg, day 1 and 15) except for down-staging. After 4 courses of chemotherapy, gastric tumor and metastatic lymph nodes were reduced in size and the splenic vein thrombus was disappeared, and then total gastrectomy was performed (tub2, T2 (MP) N0 H0 M0 P0 CY0, Stage IB). S-1 medication was applied as adjuvant chemotherapy. Forty months passed from the operation, the patient remains alive with no signs of relapse. Source

A 75-year-old man was diagnosed as gall bladder carcinoma by postoperative histological examination following laparoscopic cholecystectomy. He underwent the second surgery of resection of liver bed and port sites with lymph node dissection. Isolated hepatic metastasis of 20 mm in diameter was found in S4/8 by MRI 18 months postoperatively, and stereotactic radiotherapy (52.8 Gy/4 Fr) was done for the metastatic lesion. The lesion could not be detected by CT 7 months after the radiotherapy, and thereafter no local recurrence has been observed for 24 months. However, lymph node metastasis of #9 was diagnosed 31 months postoperatively. Liniac radiotherapy (60 Gy/20 Fr)was performed and stable disease has been obtained for 9 months. The patient is alive at present of 43 months after surgery without any other site of the disease, and his quality of life is well maintained. Stereotactic radiotherapy showed an excellent local therapeutic effect without any serious complications, suggesting that this is a potent modality for isolated liver metastasis of gall bladder carcinoma.

A 70-year-old female suffered from jaundice was admitted to our hospital for a tumor in the pancreas head. CA19-9 and DUPAN-2 levels were increased in laboratory test. Enhanced abdominal computed tomography (CT) scan revealed a low density area of pancreas head. Cytology of pancreatic juice was performed by ERCP, and malignant cells were detected. Pancreaticoduodenectomy was performed under a diagnosis of pancreatic cancer (T3N1M0, stage III). Despite of adjuvant chemotherapy (gemcitabine) after surgery, CT scan revealed a low density area in the cut end of remnant pancreas at 3 months, which was accompanied with elevation of and CA19-9 and DUPAN-2 levels. We diagnosed as a recurrent pancreatic cancer of remnant pancreas without any other side of recurrence and re-resection was performed. Because of chylous ascites and depression following a second surgery, postoperative adjuvant chemotherapy could not be started. Re-recurrence was detected at 3 months after the second surgery, and she died 6 months after the surgery. Remnant or repeated pancreatectomy for local recurrent pancreatic carcinomas is extremely rare with limited number of cases reported in the literature. We report our experience, and discuss the significance of re-resection for recurrence of remnant pancreas. Source
