| 抄録 | An 87-year-old Japanese man underwent percutaneous cryoablation (PCA) therapy for his renal cell tumor. We displaced the colon from the tumor using hydrodissection. Computed tomography (CT) immediately after PCA was indicative of iceball extension to the colon wall, and a discontinuous enhancement of the colon wall was observed. We therefore performed an emergency surgery. On laparotomy, we observed a dark-purple area on the affected area of the colon, and the resected specimen showed focal, deep ulceration on the mucosal surface. Photomicrography revealed mucosal necrosis, submucosal hemorrhage, and necrotic foci in the muscularis propria, corresponding to the discontinuous colon wall enhancement on CT and the deep ulceration and dark-purple area on laparotomy. He recovered from surgery and was discharged without any complications. |

| 抄録 | A case of advanced rectal cancer treated by aggressive local and systemic treatment who has survived more than 7 years from initial recurrence is presented. A 55-year-old woman was diagnosed with advanced lower rectal cancer and underwent a low anterior resection with complete removal of all regional lymph nodes and total mesorectal excision. The tumor was diagnosed as a moderately differentiated adenocarcinoma, pStage IIIB (T3, N2a, M0). Twenty-six months after the initial surgery, local recurrence in the pelvis was detected by computed tomography, and total pelvic exenteration with distal sacrectomy (TPES) was performed after systemic chemotherapy with a molecular-targeted drug. Six months after the TPES, multiple lung metastases were detected. Consequently, the patient underwent radiofrequency ablation (RFA) and chemotherapy. The disease has since been controlled for 38 months. As volume control is essential for cancer treatment, it may be important to combine appropriate local therapy with systemic therapy to metastatic or recurrent sites in order to achieve much longer disease control. |

| 抄録 | Proton Magnetic Resonance Spectroscopy (1H-MRS) can be used to detect cerebral metabolites including N-acetylaspartate (NAA)，creatine (Cr) and choline (Ch). Hence，clinical applications of this method for neuropediatric diseases can be expected. However，regarding neuronal migration disorders，there have been only a few reported studies. We therefore examined the lH-MRS in six patients with migration disorders，ages ranged from 8months to 28years 10months with a mean of 10years 10months. Investigation was performed using Magnetom H15 (Siemens) with a repetition time of 1500 msec and an echo time of 270msec. The ratio of NAA/Cr，Ch/Cr were examined. The volume of interest with the size of 2 × 2 × 2 ～ 3 × 3 × 5cm3 was chosen in the area including lesions，and a contralateral area without lesions was also investigated. Results were as follows. 1) The ratio of NAA/Cr was low in the area with lesions in all 6cases; 1.41，1.95，2.27 and 1.71 in cases with heterotopic gray matter，0.99 in one case with polymicrogyria，an d 1.30 in one case with hemimegalencephaly，contrasted with a contralataral area without lesions: 1.89， 2.89，2.87，2.55，3.26，2.03，respectively. 2) The ratio of Ch/Cr showed no consistent difference between the area including lesions and contralataral area without lesions. Our findings of a decreased NAA/Cr ratio can be inferred to reflect the decreased numbers of neuronal cell population，or reduced metabolism in the lesions. |

| 抄録 | This retrospective study evaluated the safety and efficacy of using polidocanol with X-ray fluoroscopy for percutaneous sclerotherapy of venous malformations of the limbs, head, and neck. The subjects were 16 of 18 patients who presented to our department with venous malformations. Two patients were excluded because they were unlikely to benefit from the treatment. Of the 16 included in the study, 1 could not be treated because of inaccessibility, and another was lost to follow-up. Among the 14 cases that we were able to follow-up, 11 cases had had pain as their primary symptom. Following treatment, this symptom remained unchanged in 1 patient, was improved in 4, and had disappeared in 6; however, there was a recurrence of pain for 3 of these patients. Two patients had sought treatment for cosmetic purposes; following treatment, the lesion disappeared in one and showed a significant reduction in the other. The remaining patient presented with a primary symptom of mouth bleeding, which disappeared following treatment. There were no critical complications. Percutaneous sclerotherapy of venous malformations using polidocanol is safe and effective, and permits repeat treatments. The efficacy is especially good for resolving pain, and complications are minor. It is desirable to use fluoroscopy for these procedures |

| 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. |

| 抄録 | The aim of the present study was to assess the diagnostic usefulness of Fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in the prediction of local recurrence of malignant lung tumors by analyzing the pre-radiofrequency ablation (RFA) maximal standardized uptake value (SUVmax). We performed a historical cohort study of consecutive malignant lung tumors treated by RFA from January 2007 to May 2008 at Okayama University Hospital. We selected only lung tumors examined by PET/CT within 90 days before RFA and divided them (10 primary and 29 metastatic) into 3 groups according to their tertiles of SUVmax. We calculated recurrence odds ratios in the medium group and the high group compared to the low group using multivariate logistic analysis. After we examined the relationship between SUVmax and recurrence in a crude model, we adjusted for some factors. Tumors with higher SUVmax showed higher recurrence odds ratios (medium group;1.84, high group;4.14, respectively). The tumor size also increased the recurrence odds ratio (2.67);we thought this was mainly due to selection bias because we excluded tumors less than 10mm in diameter. This study demonstrated the pre-RFA SUVmax in PET/CT may be a prognostic factor for local recurrence of malignant lung tumors. |

| 抄録 | The application of radiofrequency ablation for the treatment of lung cancer by our group at Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences began in June 2001, and in the present report, we review our 10-year experience with this treatment modality at Okayama University Hospital. The local efficacy of radiofrequency ablation for the treatment of lung cancer depends on tumor size and the type of electrode used, but not on tumor type. An important factor for the prevention of local failure may be the acquisition of an adequate ablative margin. The combination of embolization and radiation therapy enhances the local efficacy. Local failure may be salvaged by repeating the radiofrequency ablation, particularly in small tumors. Survival rates after radiofrequency ablation are quite promising for patients with clinical stage I non-small cell lung cancer and pulmonary metastasis from colorectal cancer, hepatocellular carcinoma, and renal cell carcinoma. The complications caused by radiofrequency ablation can be treated conservatively in the majority of cases. However, attention should be paid to rare but serious complications. This review shows that radiofrequency ablation is a promising treatment for patients with lung cancer. |
