Background: The infratemporal fossa (ITF) is an anatomical lateral skull base space composed by the zygoma, temporal, and the greater wing of the sphenoid bone. Due to its difficult approach, surgical intervention at the ITF has remained a heavy burden to surgeons. The aim of this article is to review basic skull base approaches and ITF structures and to avoid severe complications based on the accurate surgical knowledge. Methods: A search of the recent literature using MEDLINE (PubMed), Embase, Cochrane Library, and other online tools was executed using the following keyword combinations: infratemporal fossa, subtemporal fossa, transzygomatic approach, orbitozygomatic approach, transmaxillary approach, facial translocation approach, midface degloving, zygomatico-transmandibular approach, and lateral skull base. Aside from our Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) trial, there have been very few randomized controlled trials. The search data for this review are summarized based on the authors' diverse clinical experiences. Results: We divided our results based on representative skull base approaches and the anatomy of the ITF. Basic approaches to the ITF include endoscopic endonasal, transzygomatic, orbitozygomatic, zygomatico-transmandibular, transmaxillary, facial translocation, and the midfacial degloving approach. The borders and inner structures of the ITF (with basic lateral skull base dissection schemes) are summarized, and the modified zygomatico-transmandibular approach (ZTMA) is described in detail. Conclusions: An anatomical basic knowledge would be required for the appropriate management of the ITF pathology for diverse specialized doctors, including maxillofacial, plastic, and vascular surgeons. The ITF approach, in conjunction with the application of microsurgical techniques and improved perioperative care, has permitted significant advances and successful curative outcomes for patients having malignancy in ITF.

위암은 치료에 있어서 조기 발견을 통한 수술 등에 의해서 치료율이 향상되었지만 조기 위암을 제외하고는 치료성적이 정체되고 있는 실정이다. 진단 당시 아직도 많은 환자들이 처음부터 수술이 어렵거나 수술이 가능하더라도 치료 후에 재발 등으로 인하여 예후가 좋지 않다. 이를 볼 때 위암의 치료에 수술 이외의 부가적인 치료가 필요하다고 보고 치료율 향상을 위한 많은 시도가 시행되어 왔다. 특히 다른 고형 암에서의 좋은 결과와 수술 전 항암 화학요법 치료의 이론적인 잇점으로 인하여 많은 기대를 가지게 하였으나 현재까지의 연구 결과 만을 볼 때는 그리 희망적이지 않다. 기존의 대부분의 연구가 2상 연구로 의미있는 결과를 유추하는데 문제점이 있고 3상 연구로 발표된 몇몇 연구는 드물기도 하지만 이를 수술 전 항암 항암화학 요법의 효과로 받아들이는 데는 문제가 많다. 순수하게 수술 전 항암 화학 요법 치료를 한 연구에서는 오히려 기대와 상반된 결과를 보이고 있다. 그러므로 현재까지의 연구 결과를 가지고 판단한다면 수술 전 항암 화학 요법의 치료는 임상 시험 범주 내에서 시행되어야 하며 임상에서 환자에게 권할 수 있는 하나의 표준 치료가 되기 위해서는 좀 더 연구가 필요하다. 현재까지의 비관적인 결과는 약제의 선택에 있어서 문제가 있으며 추후 신약 등을 포함한 약제를 이용한 연구가 필요한 실정이다.

Purpose: Lymph node (LN) metastasis is the best prognostic indicator in non-distant metastatic advanced gastric cancer. This study aimed to assess the prognostic value of various clinicopathologic factors in node-negative advanced gastric cancer. Materials and Methods: We retrospectively analyzed the clinical records of 254 patients with primary node-negative stage T2~4 gastric cancer. These patients were selected from a pool of 1,890 patients who underwent radical resection at Memorial Jin-Pok Kim Korea Gastric Cancer Center, Inje University Seoul Paik Hospital between 1998 and 2008. Results: Of the 254 patients, 128 patients (50.4%), 88 patients (34.6%), 37 patients (14.6%), and 1 patient (0.4%) had T2, T3, T4a, and T4b tumors, respectively. In a univariate analysis, operation type, T-stage, venous invasion, tumor size, and less than 15 LNs significantly correlated with tumor recurrence and cumulative overall survival. In a multivariate logistic regression analysis, tumor size, venous invasion, and less than 15 LNs significantly and independently correlated with recurrence. In a multivariate Cox proportional hazards analysis, tumor size (hazard ratio [HR]: 2.926; 95% confidence interval [CI]: 1.173~7.300; P=0.021), venous invasion (HR: 3.985; 95% CI: 1.401~11.338; P=0.010), and less than 15 LNs (HR: 0.092; 95% CI: 0.029~0.290; P<0.001) significantly correlated with overall survival. Conclusions: Node-negative gastric cancers recurred in 8.3% of the patients in our study. Tumor size, venous invasion, and less than 15 LNs reliably predicted recurrence as well as survival. Aggressive postoperative treatments and timely follow-ups should be considered in cases with these characteristics.

Purpose: We compared the quality of life (QOL) and nutritional outcomes following both Billroth I (BI) and Billroth II (BII) reconstructions after a subtotal gastrectomy in order to identify which reconstruction would produce a better QOL and nutritional outcomes and to provide better follow-up management. Materials and Methods: We studied 273 patients without evidence of recurrent disease following a curative distal subtotal gastrectomy for gastric cancer. Among them, 135 underwent a BI reconstruction and 138 a BII reconstruction. The nutritional status was assessed by using levels of hemoglobin, serum albumin, iron, and vitamin B12 and by calculating the relative body weight, the body mass index, and the percentage of body fat. The QOL was measured by using the Troidl score and by treatment-specific symptoms based on the criteria, somewhat modified by the authors, of Korenaga and others. Results: There was no significant difference in QOL between the BI and the BII groups. More than half of the patients revealed anemia, regardless of the type of reconstruction. The serum vitamin $B_{12}$ level of the BII group was lower than that of the BI group. The BII group showed a tendency toward lower hemoglobin levels and serum iron concentrations than the BI group did. Conclusions: The quality of life was not impaired in most patients after either a BI or a BII reconstruction. However, both resulted in iron deficiency anemia, although the incidence was higher after a BII reconstruction. The patient's serum iron and vitamin B12 should be measured periodically and these must be administered if the measurements reveal a below normal range.

Purpose: ${\alpha}$-fetoprotein (AFP)-producing gastric cancer is a rare tumor with high rates of liver metastasis and a poor prognosis. Many studies have been performed but there have been no comprehensive investigations of the clinicopathological and prognosis. Materials and Methods: Six hundred ninety four patients with gastric cancer who underwent a curative gastric resection in Hanyang University Hospital from February 2001 to December 2008 were evaluated retrospectively after excluding active or chronic hepatits, liver cirrhosis and preoperative distant metastasis. Among them, thirty five patients had an elevated serum level of AFP (>7 ng/ml) preoperatively. The clinicopathological features of AFP-producing gastric cancer were analyzed. Results: There was poorer differentiation, a higher incidence of lymph node metastasis, more marked lymphatic and vascular invasion in the AFP-positive group than in the AFP-negative group. The 5-year survival rate of the AFP-positive group was significantly poorer than that in the AFP-negative group (66% vs. 80%, P=0.002). A significantly higher incidence of liver metastasis was observed in the AFP-positive group than in the AFP-negative group (14.3% vs. 3.6%, P=0.002) with a shorter median time period from the operation to the metachronous liver metastasis (3.7 months vs. 14.1 months, P=0.043). Multivariate survival analysis revealed the depth of invasion, degree of lymph node metastasis and AFP-positivity to be the independent prognostic factors. Conclusions: AFP-producing gastric cancers have an aggressive behavior with a high metastatic potential to the liver. In addition, their clinicopathological features are quite different from the more common AFP-negative gastric cancer.

Background: Cholangiocarcinoma (CCA) is a very common cancer in Northeastern Thailand. Most CCA patients see a physician at a late stage when curative surgery is not possible. After diagnosis, they generally are treated by partial surgery/percutaneous drainage, chemotherapy and supportive treatment. Objective: This study aimed to assess the survival rates of CCA patients after supportive treatment. Methods: A retrospective cohort design was applied in this study. Data for 746 CCA patients were extracted from the hospital-based cancer registry of Srinagarind Hospital, Khon Kaen University. The patients were diagnosed (at least by ultrasonography) between 1 January, 2009 and 31 December, 2009 and then followed up for current status until 30 June, 2011. The cumulative survival rate was calculated by the Kaplan-Meier method, and independent prognostic factors were investigated using Cox regression. Results: The total follow-up time was 5,878 person-months, and the total number of deaths was 637. The mortality rate was therefore 10.8 per 100 person-year (95%CI : 10.1-11.7). The cumulative 3, 6, 9, 12 and 24 month survival rates were 59%, 39%, 31%, 24% and 14%, respectively. The median survival time after supportive treatment was 4 months. After adjusting for gender, age, stage, distant metastasis, histological grading and treatment, stage was a significant predictor of survival of CCA patients. Those in stage III and stage IV had a 6.78 fold higher mortality than the stage I and stage II cases (95% CI : 1.6-28.7). Conclusion: It is very important to encourage patients to see health personnel at an early stage.

담도암은 서서히 자라며 원격전이가 늦은데 비하여 완전절제가 어렵고 수술 후 재발율이 높아. 생존율은 매우 낮다. 많은 예에서 국소치료의 실패가 치료실패의 요인으로 밝혀짐에 따라 술후 방사선 치료의 중요성이 인정되어 왔다. 외부방사선치료 만으로는 충분한 선량을 조사할 수 없으므로 국소적인 고선량치료법으로서 술중방사선치료, 간질방사선치료 (interstitial irradiation), 경관방사선치료(transcatheter irradiation) 등이 사용되고 있으나 경관방사선치료의 보고는 드물다. 영남대학병원 치료방사선과에서는 진행된 담도암 1예에서 암 종괴의 부분절제 후 삽입된 T-자관을 통하여 고선량 방사선 치료를 실시하였기에 문헌고찰과 함께 보고하는 바이다.

Purpose: To explore the feasibility of maximum diameter as a response assessment method for vestibular schwannomas (VS) after stereotactic radiosurgery or fractionated stereotactic radiotherapy (RT), we analyzed the concordance of RT responses between maximum diameters and volumetric measurements. Materials and Methods: Forty-two patients receiving curative stereotactic radiosurgery or fractionated stereotactic RT for VS were analyzed retrospectively. Twelve patients were excluded: 4 did not receive follow-up magnetic resonance imaging (MRI) scans and 8 had initial MRI scans with a slice thickness >3 mm. The maximum diameter, tumor volume (TV), and enhanced tumor volume (ETV) were measured in each MRI study. The percent change after RT was evaluated according to the measurement methods and their concordances were calculated with the Pearson correlation. The response classifications were determined by the assessment modalities, and their agreement was analyzed with Cohen kappa statistics. Results: Median follow-up was 31.0 months (range, 3.5 to 86.5 months), and 90 follow-up MRI studies were analyzed. The percent change of maximum diameter correlated strongly with TV and ETV (r(p) = 0.85, 0.63, p = 0.000, respectively). Concordance of responses between the Response Evaluation Criteria in Solid Tumors (RECIST) using the maximum diameters and either TV or ETV were moderate (kappa = 0.58; 95% confidence interval, 0.32-0.85) or fair (kappa = 0.32; 95% confidence interval, 0.05-0.59), respectively. Conclusions: The percent changes in maximum diameter and the responses in RECIST were significantly concordant with those in the volumetric measurements. Therefore, the maximum diameters can be used for the response evaluation of VS following stereotactic RT.
