Since reported in the JCOG9907 trial, neoadjuvant chemotherapy prior to surgery has become the standard treatment for advanced (Stage II/III) esophageal cancers. However, more powerful neoadjuvant chemotherapy is required for the treatment of locally advanced cases or cases involving multiple lymph node metastases. At our institute, DCF therapy (docetaxel, cisplatin, and 5-fluorouracil) is administered selectively for the treatment of patients with far-advanced esophageal cancer. We treated 53 thoracic esophageal cancer patients who underwent surgery following neoadjuvant chemotherapy between January 2010 and December 2012. FP therapy (cisplatin and 5-fluorouracil) was administered to 43 patients, and DCF therapy to 7 patients who had far-advanced esophageal cancer. All patients treated with DCF therapy experienced grade 3 and 4 adverse events. With the exception of 1 patient, all patients who received DCF therapy could undergo curative surgery. DCF therapy could become an effective preoperative chemotherapy.

In our institute, we introduced PET-CT examination as the preoperative and postoperative screening for esophageal cancer patients in April 2006. During two years before the introduction of PET-CT examination, we performed an intensive local control therapy (operation, RFA, definitive chemoradiotherapy) to 13 cases with single region recurrence (including 5 cases of cervical lymph nodes recurrence, 5 of local recurrence, 3 of distant metastatic recurrence). On the other hand, we performed an intensive local control therapy to 21 cases (including 4 cases of cervical lymph nodes recurrence, 10 of local recurrence, and 7 of distant metastatic recurrence) during two years after the introduction of PET-CT examination. In any pattern, there was a tendency of improvement in the prognosis of recurrent esophageal cancer patients. These results raised the possibility that PET-CT examination was useful for an early detection of the recurrent lesions in postoperative follow-up for esophageal cancer patients. And there might be a chance of curability in patients with single region recurrence by the early detection.

We report a case of a woman in her sixties having primary duodenal carcinoma with multiple liver metastases who was treated with oxaliplatin in combination with infusional 5-fluorouracil/Leucovorin(FOLFOX regimen). After completing 2 courses of the chemotherapy, computed tomography showed a partial response without any severe adverse events. Now at 8 months, the PR stage has been maintained. So far, no standard therapeutic strategy for metastatic duodenal carcinoma has been developed. However, we suggest a FOLFOX regimen can be highly effective as a safe approach for continuously maintaining the quality of life of patients with this rare type of cancer.

We report two resected cases of advanced gastric cancer with peritoneal dissemination after successful treatment with TS-1 plus low-dose CDDP. Patient 1 presented with right hypochondralgia and underwent laparotomy with diagnosis of type 4 gastric cancer by gastrointestinal fiberscopy. However, the tumor was judged to be unresectable due to peritoneal dissemination, and chemotherapy was performed. At the completion of course 1, he underwent laparotomy again. Although the tumor involved the body of the pancreas and transverse colon, there was no peritoneal dissemination. Therefore, a total gastrectomy was performed with distal pancreatectomy, partial colectomy, cholecystectomy, and D2 lymph node dissection. Patient 2 presented with anorexia and was diagnosed with type 3 gastric cancer by gastrointestinal fiberscopy. CT revealed the tumor was unresectable due to peritoneal dissemination, and so chemotherapy was performed. He underwent laparotomy at the completion of course 3. There was no peritoneal dissemination, so a total gastrectomy was performed with cholecystectomy and D2 lymph node dissection. Both patients remain alive and in good condition without any signs of recurrence after surgery.
