[A case report of neuroendocrine carcinoma of the stomach with liver metastases curatively resected after neoadjuvant chemotherapy].

The patient was a 73-year-old male with advanced gastric cancer in the lesser curvature of the antrum.Abdominal computed tomography revealed multiple liver metastases(S5, S8).He was diagnosed with clinical Stage IV gastric cancer (cT3N0M1H1).He received 3 courses of combined neoadjuvant chemotherapy with capecitabine, cisplatin, and trastuzumab because immunostaining indicated the tumor was human epidermal growth factor receptor 2(HER2)-positive.The therapeutic response, as assessed by imaging studies, was partial for the primary lesions and stable for liver metastases.Distal gastrectomy, D2 lymph node dissection, and S5 extended subsegmentectomy of the liver were performed.Histopathological findings indicated that both the primary tumor and liver metastases were neuroendocrine carcinoma.The patient declined post-operative adjuvant chemotherapy and he is alive 6 months after the surgery with no evidence of recurrence.Surgery with neoadjuvant chemotherapy appears to be a promising option for advanced gastric cancer with liver metastases.

[A case report of long-term survival of endocrine cell carcinoma of the esophagus with chemo-radiation therapy].

The patient was an 84-year-old man, who was diagnosed with cT3N2 (101L, 109L) M0, stage III esophageal cancer. The tumor, immunohistochemically, was stained positive for CD56 and NSE yielding a definitive diagnosis of endocrine cell carcinoma of the esophagus. We selected chemo-radiation therapy (5-FU/CDDP and 2 Gy/day total 60 Gy) for this patient. As adjuvant chemotherapy, 7 courses of chemotherapy with 5-FU/CDDP, was performed. At 8 months from the chemo-radiation therapy, the disease was diagnosed as cCR. But two years later, lung metastasis appeared, so we started chemotherapy with docetaxel/CDDP/5-FU. After 2 courses, lung metastasis was almost disappeared. He has been survived for four years and five months after chemo-radiation. This case suggests that chemo( FP) -radiation therapy and adjuvant chemotherapy could be an effective treatment for endocrine cell carcinoma of the esophagus.

Unusual atrophic change after repeated arterial therapy for hepatocellular carcinoma: report of a case.

We report the case of a 45-year-old man with advanced hepatocellular carcinoma (HCC) who was able to undergo radical surgery after repeated transarterial therapy. Transarterial chemoembolization was repeated three times, and thereafter, transarterial infusion chemotherapy using Lipiodol was performed on the right hepatic artery. Because notable atrophy of the right lobe and compensated hypertrophy of the left lobe were detected after this therapy, an extended right lobectomy could be performed. Histologically, the HCC showed complete necrosis. The remarkable atrophic change of the right lobe was thought to be due to an obstruction of the right portal veins by the spread of inflammation around the bile duct necrosis, in addition to the narrowing of the hepatic artery. A thorough understanding of this phenomenon and the development of methods to clinically apply it in the treatment of cancer patients may thus lead to an increase in the percentage of resectable cases of advanced HCC.
