抄録  We report the case of a 61-old-man with a primary malignant melanoma of the esophagus, an extremely rare and highly aggressive malignancy. He presented with dysphagia, and we performed an upper gastrointestinal endoscopy that detected a tumor in the thoracic part of the esophagus. The biopsy showed malignant melanoma. PET/CT, endoscopy and an esophagogram showed that a 70-mm scaled type 2+1 tumor in the thoracic esophagus and no metastases. We diagnosed a cT3cN0cM0 cStage II tumor. We then performed a subtotal esophagectomy with two-field lymph node dissection and esophagogastrostomy via a retrosternal route. The pathological examination of the resected specimens confirmed that the type 2+1 tumor was PMME (pT2N0M0 pStage II). We administered six courses of postoperative adjuvant chemotherapy with dacarbazine, and the patient has had no recurrence for 17 months after the surgery.

抄録  Esophageal endocrine cell carcinoma is extremely rare. We report a case of esophageal endocrine cell carcinoma showing histological complete response to neoadjuvant chemotherapy with docetaxel/cisplatin/5-fluorouracil (DCF). A 66-year-old man had been experiencing epigastralgia, and a type 2 tumor in the thoracic part of esophagus was detected by upper endoscopy. The biopsy showed endocrine cell carcinoma. PET/CT, endoscopy and an esophagogram showed that the patient had a 70-mm scaled type 2 tumor in the middle thoracic esophagus, and they also revealed lymph node metastases (no. 106recR). We diagnosed a cT3cN1cM0 cStage III tumor. With two courses of DCF treatment, both the primary tumor and lymph node metastases showed a partial response. We performed a subtotal esophagectomy with three-field lymph node dissection. The pathological examination of the resected specimens revealed no malignant cells in the esophagus or lymph nodes, and we concluded that the pathological effect of the DCF treatment was Grade 3.

抄録 Autophagy is a catabolic process that produces energy through lysosomal degradation of intracellular organelles. Autophagy functions as a cytoprotective factor under physiological conditions such as nutrient deprivation, hypoxia, and interruption of growth factors. On the other hand, infection with pathogenic viruses and bacteria also induces autophagy in infected cells. Oncolytic virotherapy with replication-competent viruses is thus a promising strategy to induce tumor-specific cell death. Oncolytic adenoviruses induce autophagy and subsequently contribute to cell death rather than cell survival in tumor cells. We previously developed a telomerase-specific replication-competent oncolytic adenovirus, OBP-301, which induces cell lysis in tumor cells with telomerase activities. OBP-301-mediated cytopathic activity is significantly associated with induction of autophagy biomarkers. In this review, we focus on the tumor-suppressive role and molecular basis of autophagic machinery induced by oncolytic adenoviruses. Addition of tumor-specific promoters and modification of the fiber knob of adenoviruses supports the oncolytic adenovirus-mediated autophagic cell death. Autophagy is cooperatively regulated by the E1-dependent activation pathway, E4-dependent inhibitory pathway, and microRNA-dependent fine-tuning. Thus, future exploration of the functional role and molecular mechanisms underlying oncolytic adenovirus-induced autophagy would provide novel insights and improve the therapeutic potential of oncolytic adenoviruses.

抄録 An 80-year-old woman, who had been administered α-glucosidase inhibitor for diabetes, was brought to the hospital with the sensation of abdominal fullness and pain. Abdominal computed tomography indicated pneumatosis cystoides intestinalis (PCI) in the small intestinal wall, with free air within the abdomen. A blood examination showed no increases in white blood cells or C-reactive protein level. The patientʼs condition improved with conservative therapy. PCI with pneumoperitoneum induced by α-glucosidase inhibitor is rare, with only 27 cases (excluding the present case) reported in Japan to date. In PCI with pneumoperitoneum, differentiation from gastrointestinal perforation is important and following the clinical symptoms over time is vital.

抄録 We present a case of living donor liver transplantation to a 3-year disease-free survivor of liver resection for hepatocellular carcinoma (HCC) with major portal vein invasion. A 48-year-old man had HCC in the right lobe with a portal venous tumor thrombus extending into the left portal vein. An extended right lobectomy with thrombectomy was performed to remove the thrombus. Three years after liver resection, the patient experienced liver failure, with massive ascites and jaundice due to the formation of a thrombus in the main and left portal veins. During the 3 years after liver resection, no metastasis or recurrence of HCC had been detected, and tumor markers had been within normal ranges. The portal venous thrombus did not show any arterial enhancement under contrast-enhanced computed tomography, suggesting that the co-existence of any HCC component in the portal venous thrombus may have been negative. Based on these findings, living donor liver transplantation was performed using a right lobe graft from the patientʼs son. The patient is alive at 87 months after the transplantation, with no evidence of HCC recurrence.

抄録 We retrospectively evaluated the accumulation of fluorodeoxy glucose (FDG) in pulmonary malignancies without local recurrence during 2-year follow-up on positron emission tomography (PET)/computed tomography (CT) after radiofrequency ablation (RFA). Thirty tumors in 25 patients were studied (10 non-small cell lung cancers;20 pulmonary metastatic tumors). PET/CT was performed before RFA, 3 months after RFA, and 6 months after RFA. We assessed the FDG accumulation with the maximum standardized uptake value (SUVmax) compared with the diameters of the lesions. The SUVmax had a decreasing tendency in the first 6 months and, at 6 months post-ablation, FDG accumulation was less affected by inflammatory changes than at 3 months post-RFA. The diameter of the ablated lesion exceeded that of the initial tumor at 3 months post-RFA and shrank to pre-ablation dimensions by 6 months post-RFA. SUVmax was more reliable than the size measurements by CT in the first 6 months after RFA, and PET/CT at 6 months post-RFA may be more appropriate for the assessment of FDG accumulation than that at 3 months post-RFA.
