Gallbladder (GB) cancer is highly malignant neoplasm found in advanced stage and chemotherapy commonly plays a palliative role in GB cancer. We report a case of unresectable GB cancer treated with chemotherapy followed by extended cholecystectomy. Fifty-six-year-old male visited our hospital with weight loss and dyspnea on exertion. Computed tomography detected pulmonary embolism and diffuse GB wall thickening with para-aortic lymph node enlargement. The length of common channel was 23mm at magnetic resonance cholangiopancreatography which stands for anomalous union of the pancreaticobiliary duct. Anticoagulation was started for pulmonary embolism. GB wall mass was regarded as unresectable GB cancer with distant lymph node metastasis. Gemcitabine and cisplatin combination chemotherapy was carried out for 6 cycles. Primary tumor was stationary but multiple enlarged lymphnodes were almost completely disappeared. Extended cholecystectomy with hepaticojejunostomy was performed. Post-operative tumor stage was T3N1 (stage IIIB) and R0 resection was achieved. After operation he has no evidence of disease recurrence for 6 months.

Embryonal carcinoma of the mediastinum is a very uncommon disease. This is a report of an embryonal carcinoma in the mediastinum found in a 25 years old Korean male patient who had been suffering from chest pain and intractable coughing for 6 months. 5 weeks prior to this admission hemoptysis and high fever were followed. Right exploratory thoracotomy was performed under the impression of a mediastinal tumor, but found to be unresectable. Irradiation therapy was tried, but no response was observed. Patient expired on 78th day postoperatively.

Although surgical resection remains the best option as potentially curative therapy for hepatocellular carcinoma, radiofrequency thermal ablation has begun to receive much attention as an effective minimally invasive technique for the local control of unresectable malignant hepatic tumors. Most recent radiofrequency devices equipped with a powerful generator and larger needle electrode permit larger thermal lesions, up to 5 cm in diameter, with a single ablation. In this article, the author reviews the technical developments and early clinical results obtained with radiofrequency ablation techniques.

Purpose: To determine the prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases. Materials and Methods: Sixteen patients received whole liver radiotherapy (WLRT) between January 1997 and June 2013. A total dose of 21 Gy was delivered in 7 fractions. Results: The median survival time after WLRT was 9 weeks. In univariate analysis, performance status, serum albumin and total bilirubin level, liver volume and extrahepatic metastases were associated with survival. The mean liver volume was significantly different between subgroups with and without pain relief (3,097 and 4,739 mL, respectively; p = 0.002). Conclusion: A larger liver volume is a poor prognostic factor for survival and also a negative predictive factor for response to WLRT. If patients who are referred for WLRT have large liver volume, they should be informed of the poor prognosis and should be closely observed during and after WLRT.

Sorafenib (Nexavar) has been regarded as a treatment for unresectable hepatocellular carcinoma (HCC), with side effects that include hand-foot skin reaction, diarrhea, rash, fatigue, hypertension, nausea, anorexia, weight loss, and alopecia. Thyroid disorder, such as endocrine side effect, has also been reported. However no case involving adrenal insufficiency has been reported. Here, we report a case of adrenal insufficiency which occurred after taking sorafenib in a patient with HCC. A 56-year-old man visited our hospital due to right upper quadrant abdominal pain and he was diagnosed as multiple disseminated and unresectable HCCs with portal vein invasion; therefore transarterial chemoembolization was performed and sorafenib administration was started. Two months later, he was admitted to the hospital complaining of severe fatigue. The laboratory results showed cortisol of <$0.2{\mu}g/dL$ and adrenocorticotropic hormone of <1.00 pg/mL. The patient had no history of taking steroids or herbal medications. Secondary adrenal insufficiency was diagnosed and prednisolone 10 mg per day was started immediately; as a result, fatigue remarkably improved. This may be the first report indicating a possible association between sorafenib and adrenal insufficiency and it implies that the possibility of adrenal insufficiency should be considered in patients taking sorafenib who complain of severe fatigue.

A total of 93 patients with rectal cancer treated with radiotherapy at department of Radiation Oncology, Yonsei University College of Medicine, Yonsei Cancer Center between January 1974 and December 1983 are retrospectively analysed. The patients are divided into three groups as follows: I. Postoperative radiotherapy, II. Postoperative recurrent, III. Unresectable or Inoperable group. In postoperative radiotherapy group, overall 5 year survival rate is $34.8\%$ and prognostic factors are presence of obstruction and degree of differentiation. In postoperative recurrent group, overall 2 year survival rate is $7.4\%$ with median survival of 13 months and prognostic factors are RT responsiveness and sex, and the local failure rate is $22.7\%$. In unresectable or inoperable group, overall 2 year survival rate is $19.8\%$ with median survival of 12.6 months and prognostic factors are RT responsiveness and RT dose. The complications for RT are not significant and are acceptable in all patients.

In order to improve the control of large unresectable(>6cm) and fixed N3(TNM-UICC) metastatic neck nodes, local hyperthermia(HT) has been combined with radiation therapty (RT) in Yonsei cancer center. From April 1985 to april 1988, a total of 18 patients of head and neck cancer with metastatic large unresectable and fixed cervical neck nodes who underwent combined RT and HT were analyzed. Of 18 patients, complete response rate was 39% (7 pt.) partial response 39% (7 pt.) and overall response rate was 78%. Acute side effects of these combined modalities were found in 8 patients and which were mainly cutaneous reaction such as erythema, dry and moist desquamation but recovered spontaneously in all patients after treatment. Factors of maximum tumor temperature above $43^{\circ}\C$ and MDF(multiple daily fractionation) showed more favorable response rate but not statistically sinificant. Two year actuarial survival rate of all patients was 35.4%.

Purpose: Infantile hepatic hemangioendothelioma (IHHE) is the most common type of hepatic vascular tumor in infancy. We conducted this study to review our clinical experience of patients with IHHE and to suggest management strategies. Methods: We retrospectively analyzed the medical records of 23 IHHE patients (10 males, 13 females) treated at the Asan Medical Center between 1996 and 2009. Results: Median age at diagnosis was 38 days (range, 1 to 381 days). Seven patients (30%) were diagnosed with IHHE based on sonographically detected fetal liver masses, 5 (22%) were diagnosed incidentally in the absence of symptoms, 5 (22%) had congestive heart failure, 3 (13%) had skin hemangiomas, 2 (9%) had abnormal liver function tests, and 1 (4%) had hepatomegaly. All diagnoses were based on imaging results, and were confirmed in three patients by histopathology analysis. Six patients were observed without receiving any treatment, whereas 12 received corticosteroids and/or interferonalpha. One patient with congestive heart failure and a resectable unilobar tumor underwent surgical resection. Three patients with congestive heart failure and unresectable tumors were managed by hepatic artery embolization with/without medical treatment. At a median follow-up of 29 months (range, 1 to 156 months), 21 (91%) patients showed complete tumor disappearance or >50% decrease in tumor size. One patient died due to tumor-related causes. Conclusion: IHHE generally has a benign clinical course with low morbidity and mortality rates. Clinical course and treatment outcome did not differ significantly between medically treated and non-treated groups. Surgically unresectable patients with significant symptoms may be treated medically or with hepatic artery embolization.

Total of 53 patients of unresectable and recurrent rectal cancer treated with neutron beam during the period from Oct.1987 to Apr.1992 were analyzed. Dose fractionation for the neutron only group was 1.5 Gy per fraction,3 fraction per week,21 Gy/41/2 wks for 42 patients out of 53 ($76{\%}$). Neutron only but modified fractionation schedule ($10{\%}$ more or less of total dose) was applied for 9 patients, and mixed beam (neutron boost) was for 4 patients, Complete tumor response was obtained in 40 patients ($76{\%}$, response rate). Local control rate was 28 out of 53 ($53{\%}$). Statistically significant better prognostic factors for local control were age below 49 years old (15/22, $68{\%}$) than above 50 years old (13/31, $42{\%}$), male (20/32, $63{\%}$) than female (8/21, $38{\%}$), tumor size less than 5 cm and non-metastatic (16/24, $67{\%}$) than size more than 5 cm or metastatic (12/29, $41{\%}$). Major complication had developed in 7 patients ($13{\%}$). Two year overall survival rate by Kaplan-Meier method was $30{\%}$, but it was rised to, $47{\%}$ when the turner was less than 5 cm non-metastatic.

Purpose: To assess real-world treatment patterns, health care utilization, costs, and survival among Medicare enrollees with locally advanced/unresectable or metastatic gastric cancer receiving standard first-line chemotherapy. Materials and Methods: This was a retrospective analysis of the Surveillance, Epidemiology, and End Results-Medicare linked database (2000~2009). The inclusion criteria were as follows: (1) first diagnosed with locally advanced/unresectable or metastatic gastric cancer between July 1, 2000 and December 31, 2007 (first diagnosis defined the index date); (2) ${\geq}65$ years of age at index; (3) continuously enrolled in Medicare Part A and B from 6 months before index through the end of follow-up, defined by death or the database end date (December 31, 2009), whichever occurred first; and (4) received first-line treatment with fluoropyrimidine and/or a platinum chemotherapy agent. Results: In total, 2,583 patients met the inclusion criteria. The mean age at index was $74.8{\pm}6.0years$. Over 90% of patients died during follow-up, with a median survival of 361 days for the overall post-index period and 167 days for the period after the completion of first-line chemotherapy. The mean total gastric cancer-related cost per patient over the entire post-index follow-up period was United States dollar (USD) $70,808{\pm}56,620$. Following the completion of first-line chemotherapy, patients receiving further cancer-directed treatment had USD 25,216 additional disease-related costs versus patients receiving supportive care only (P<0.001). Conclusions: The economic burden of advanced gastric cancer is substantial. Extrapolating based on published incidence estimates and staging distributions, the estimated total disease-related lifetime cost to Medicare for the roughly 22,200 patients expected to be diagnosed with this disease in 2014 approaches USD 300 millions.
