This study aimed to discuss the consumption of alcohol as a risk factor for major cancers. We performed a search in the PubMed database, using the following inclusion criteria: meta-analysis published in English in the last 10 years that addressed the relationship between alcohol and the risk of developing cancer. The results indicate that moderate to heavy consumption of alcohol increases the risk of developing cancer of the oral cavity and pharynx, esophagus, stomach, larynx, colorectum, central nervous system, pancreas, breast and prostate. This review did not find any association between alcohol consumption and an increased risk of cancers of the lung, bladder, endometrium and ovary. It was also observed that alcohol consumption may be inversely related to thyroid cancer. Our systematic review has confirmed consumption of alcohol as a risk factor for the development of several types of cancer.

Paraneoplastic pemphigus (PNP) is a rare and often fatal autoimmune blistering disease accompanied by both benign and malignant neoplasms. Usually, oral, skin, and mucosal lesions are the earliest manifestations shown by PNP patients. Oral ulcers are initial lesions in various autoimmune diseases like pemphigus, bullous pemphigoid, erythema multiforme, graft-versus-host, lichen planus, it does not improved despite of high-dose steroid therapy. We report a-35-year-old female who presented oral ulceration, lip crust and skin lesions. By doing several examinations, such as enzyme-linked immunosorbent assay, incisional biopsy with indirect immunofluorescence, she was diagnosed PNP with non-Hodgkin's lymphoma on pancreas.

Pancreatic neuroendocrine tumors are rare pancreatic neoplasms comprising 1-2% of all pancreatic tumors and typically present high attenuating mass on arterial and venous phase images, due to their rich capillary network. A 70-year-old South Korean female visited our hospital presenting with jaundice and dark urine color. She had received an operation for treatment of small bowel perforation seven years ago. On physical examination, icteric sclera was observed but otherwise unremarkable. Laboratory tests were abnormal liver function test and suspected obstructive jaundice. Computed tomography revealed 4 cm sized cystic mass lesion with homogeneous low attenuation in the head of pancreas and distal common bile duct was compressed by the mass. During review of past medical records, we found that the mass was observed and measured about 1.7 cm seven years ago. To resolve obstructive jaundice, pylorus preserving pancreaticoduodenectomy was performed and diagnosed with well differentiated pancreatic neuroendocrine carcinoma with intermediate grade.

Purpose: To report the initial clinical experience with single-incision laparoscopic gastric wedge resection for submucosal tumors. Materials and Methods: The medical records of 10 patients who underwent single-incision laparoscopic gastric wedge resection between July 2009 and March 2011 were reviewed retrospectively. The demographic data, clinicopathologic and surgical outcomes were assessed. Results: The mean tumor size was 2.5 cm (range, 1.2~5.0 cm), and the tumors were mostly located on the anterior wall (4/10) or along the greater curvature (4/10), of the stomach. Nine of ten procedures were performed successfully, without the use of additional trocars, or conversion to laparotomy. One patient underwent conversion to multiport laparoscopic surgery, to get simultaneous cholecystectomy safely. The mean operating time was 66.5 minutes (range, 24~132 minutes), and the mean postoperative hospital stay was 5 days (range, 4~7 days). No serious perioperative complications were observed. Of the 10 submucosal tumors, the final pathologic report revealed 5 gastrointestinal stromal tumors, 4 schwannomas, and 1 heterotopic pancreas. Conclusions: Single-incision laparoscopic gastric wedge resection for gastric submucosal tumors is feasible and safe, when performed by experienced laparoscopic surgeons. This technique provides favorable cosmetic results, and also short hospital stay and low morbidity, in carefully selected candidates.

림프계는 염증 및 악성 세포의 확산 경로를 제공한다. 종양이 확산되는 림프절의 위치와 림프 배액 경로를 인지하는 것은 종양의 병기 결정, 치료 방법 선택 및 환자의 예후 예측에 중요하다. 복강 내 악성 종양에서 림프절 전이는 흔하기 때문에 림프절 전이를 발견하고 질병의 확산 방식을 이해하는 것은 영상의학과 의사에게 필수적이다. 이 임상화보에서는 도식적인 그림들과 림프절을 색으로 표시한 CT 영상을 사용하여, 상부 및 하부 위장관, 간, 담낭, 담관 및 췌장의 림프절 위치와 이름, 그리고 림프 배수 경로에 관해 기술하였다. 또한 각 장기에서 발생하는 악성 종양의 국소 림프절의 종류에 대해 기술하고 몇몇 증례의 영상을 제시하였다.

Background: The gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN) is the most common type of neuroendocrine neoplasm. We summarized data in our centre to investigate the clinicopathological features, diagnostic methods, therapeutic approaches and prognosis for this neoplasm to increase knowledge of this disease in Asian populations. Method: A total of 122 patients treated at Sun Yet-san Memorial Hospital of Sun Yat-sen University between January 2000 and December 2011 were analyzed retrospectively. Results: Pancreas was the most common site of involvement (65/122, 53.3%); this disease has no special symptoms; positive rates of chromogranin A (CgA) and synaptophysin (Syn) were 81.1% and 87.7%, respectively. The positive rate of Syn had statistical difference among the three grades, but not CgA. Some 68 patients had G1 tumors, 32 G2 tumors and 22 G3 tumors, and Chi-square test showed that higher grading was correlated with worse prognosis (${\chi}^2=32.825$, P=0.0001). A total of 32 patients presented with distant metastasis, and 8 cases emerged during following up. Cox proportional hazards regression modeling showed that the tumor grade (P=0.01), lymphatic metastasis (P=0.025) and distant metastasis (P=0.031) were predictors of unfavorable prognosis. The overall 5-year survival rate was 39.6%, the 5-year survival rate of G1 was 55.7%, and the G2 and G3 were 34.2% and 0%, respectively. Conclusions: The incidence of gastroenteropancreatic neuroendocrine tumors has risen over the last 12 years. All grades of these diseases metastasize readily, and further research regarding the treatment of patients after radical surgery is needed to prolong disease-free survival.

Purpose: To evaluate the effectiveness and feasibility of chemoradiotherapy (CRT) using simultaneous integrated boost-intensity modulated radiotherapy (SIB-IMRT) in locally advanced pancreatic cancer (LAPC) patients. Materials and Methods: Between January 2011 and May 2015, 47 LAPC patients received CRT using SIB-IMRT. Prior to SIB-IMRT, 37 patients (78.7%) received induction chemotherapy (IC-CRT group) and remaining 10 patients (21.3%) did not received induction chemotherapy (CRT group). During SIB-IMRT, all patients received concomitant chemotherapy, with gemcitabine (n = 37) and capecitabine (n = 10). Results: At the time of analysis, 45 patients had died and 2 patients remained alive and the median follow-up time was 14.2 months (range, 3.3 to 51.4 months). For all patients, the median times of local progression-free survival (LPFS), progression-free survival (PFS), and overall survival (OS) were 18.1, 10.3, and 14.2 months, respectively. The median time of LPFS between IC-CRT and CRT groups was similar (18.1 months vs. 18.3 months, p = 0.711). IC-CRT group had a higher trend in PFS (10.9 months vs. 4.1 months, p = 0.054) and had significantly higher OS (15.4 months vs. 9.5 months, p = 0.007) than CRT group. In multivariate analysis, the use of induction chemotherapy and tumor response were significant factors associated with OS (p < 0.05, each). During SIB-IMRT, toxicity of grade ≥3 was observed in 7 patients (14.9%) in all patients. Conclusions: CRT using SIB-IMRT is feasible and promising in LAPC patients.

목적 진행성 위암의 인접 장기 침범을 결정함에 있어 우측와위 CT의 추가적 가치를 살펴보았다. 대상과 방법 병리학적으로 입증된 T4a (p4a), 외과적 그리고 병리학적으로 입증된 T4b (sT4b, pT4b) 위암 환자 중 좌후사위 및 우측와위 자세가 포함된 프로토콜의 CT를 촬영한 환자 총 728명이 포함되었다. 2명의 영상의학과 전문의가 2주 간격으로 각각 우측와위 CT 없이, 우측와위 CT와 함께 좌후사위 CT를 분석하여 5점 척도를 사용하여 T 병기를 평가하고 종양과 인접 장기 사이의 "미끄러짐 징후"의 존재를 기록했다. 결과 564명의 환자(77.4%)가 pT4a로 진단되었다. 65명(8.9%)과 99명(13.6%)의 환자가 각각 pT4b, sT4b로 진단되었다. 좌후사위 CT 단독 분석에 비하여 우측와위 CT가 추가되었을 때, T4b와 T4a를 구별하기 위한 곡선 아래 면적(area under the curve; 이하 AUC) 값이 두 검토자 모두에서 유의하게 증가했다(Ps < 0.001). 하위집단분석에서 T4a와 췌장을 침범한 T4b 위암을 구별하기 위한 AUC 값 역시 두 검토자 모두에서 증가했다(Ps < 0.050). 관찰자 간 일치도 역시 향상되었다(가중 카파 계수, 0.296-0.444). 결론 진행위암에서 인접 장기 침범을 판단함에 있어, 우측와위 CT가 추가되었을 때 좌후사위 CT 단독 분석에 비해 더 높은 AUC 값과 관찰자 간 일치도를 보임으로써 추가적 가치가 있었다.

췌장에는 다양한 종류의 종양 및 종양 유사 병변들이 생길 수 있다. 이 가운데, 췌장선암은 췌장의 가장 흔한 종양으로서 일반적으로 췌장암이라고 하면 이 종양을 가리킨다. 최근에는 영상 검사의 기술적 진보와 이용이 증가하면서 췌장의 희귀 종양 및 종양 유사 병변들의 발견 빈도가 증가하고 있다. 췌장의 드문 종양 및 종양과 유사한 병변들은 치료 방침과 예후가 췌장선암과 다르기 때문에 이들 질환의 감별은 임상적으로 중요한 의의가 있다. 영상 검사는 포상세포암이나 신경초종 등의 희귀 종양 및 자가면역 췌장염 또는 염증성 거짓종양과 같은 종양 유사 병변들과 췌장선암의 감별 진단에 중요한 역할을 하지만 영상 소견만으로 이들 질환을 정확히 구분하는 것은 한계가 있다. 이 논문에서는 췌장에서 생길 수 있는 희귀 종양 및 종양 유사 병변들의 다양한 영상 소견들과 췌장선암과의 감별에 있어 도움이 되는 특징들을 제시하고자 한다.
