RESUMEN
We report a case of long-term survival after combination chemotherapy and surgical resection of a cancer of unknown primary site[ CUPs]. A septuagenarian female was identified as having high blood levels of carcinoembryonic antigen (CEA) during follow-up monitoring of asthma. Endoscopy and imaging studies including computed tomography (CT) and positron emission tomography (PET)-CT revealed a malignant lymph node adjacent to the abdominal aorta; however, no other lesion was detected. Therefore, we performed CT-guided biopsy and diagnosed the lesion to be a lymph node metastasis of poorly differentiated adenocarcinoma. As we considered this as a systemic disease, the patient received 2 courses of combination chemotherapy with 5-fluorouracil( 5-FU)/cisplatin( CDDP) and achieved a partial response (PR). Later, the patient received S-1 therapy as second-line chemotherapy and S-1/irinotecan( CPT-11) as third-line chemotherapy in an outpatient clinic. However, the tumor continued to grow, and therefore, we decided to perform surgical resection. Histopathological examination of the resected specimen yielded a diagnosis of metastatic adenocarcinoma of the lymph node. The patient has been well without any signs of recurrence for more than 9 years since surgery. As CUPs is generally associated with poor prognosis, this case raises the possibility that combination therapy might improve convalescence.

Duodenal stenting for malignant disease related to gastric outlet obstruction(GOO) has been covered by health insurance in Japan since April 2010. We inserted WallFlexTM duodenal stents(WDS) in 4 patients with GOO caused by unresectable gastric cancer. WDS insertion was successful in all 4 cases. Duodenal perforation occurred in 1 case. One case each of stent obstruction and stent migration occurred. All patients could eat a soft-food diet for 3-6 months (median, 5.3 months). Survival time ranged between 5 and 14 months (median, 6 months). Three patients underwent S-1 combination chemotherapy. Duodenal stenting is expected to be effective for advanced gastric cancer related to GOO.

Eosinophilic gastroenteritis (EG) is an inflammation of the digestive tract that is characterized by eosinophilic infiltration. There are no specific symptoms, and are related to the layer in which eosinophilic infiltration is observed. A 69-year-old Japanese man presented to our hospital with a history of general malaise, diarrhea, and dysgeusia. Esophagogastroduodenoscopy showed reddish elevated lesions that were edematous all over the gastric mucosa. In addition, three tumors were also observed. The biopsies of the reddish elevated mucosa revealed eosinophilic infiltration and tubular adenocarcinoma from the tumors. Colonoscopy showed abnormal reddish elevated mucosa. The biopsies from the reddish elevated mucosa showed eosinophilic infiltration. From the abdominal contrast computed tomography scan, tumor stain was seen in the anterior wall of the gastric body. No ascites, intestinal wall thickening, or lymph node swelling were found. A slight elevation in the serum immunoglobulin E (IgE), 480 IU/ml, was found from the laboratory test results; other laboratory results were within normal limits including the number of peripheral eosinophils. No specific allergen was found from the multiple antigen simultaneous test and from the skin patch test. The parasitic immunodiagnosis was negative. He was diagnosed with EG associated with gastric cancer and underwent total gastrectomy, regional lymph node dissection with reconstruction by a Roux-en-Y method. He was prescribed prednisolone after the operation and showed a good clinical response. There are many case reports on EG, but none of them were associated with cancer. We encountered a case of EG associated with multiple gastric cancer; the patient underwent total gastrectomy.

As the treatment for inoperable advanced gastric cancer, S-1/CDDP combination therapy (SP chemotherapy) has become a standard treatment. In our hospital, a second course of chemotherapy was performed on an outpatient basis in order to improve a traditional QOL. In this case, it showed remarkable effects in 15 months after starting chemotherapy. Then gastrectomy was performed. Histological findings of the resected specimens confirmed pCR in all tumors. We report on progress of this case and explain about the ingenuity of SP chemotherapy.
