Background & Objectives: In patients with gastric cancer, the most frequently reported family history of cancer also involves the stomach. The aim of this study was to assess the presence of gastric precancerous lesions in first-degree relatives of patients with gastric cancer and to compare the obtained results with those of individuals with no such family history. Methods: Between 2007 and 2009, 503 consecutive persons more than 30 years old were enrolled in the study covering siblings, parents or children of patients with confirmed adenocarcinoma of stomach. The control group was made up of 592 patients who were synchronously undergoing upper gastrointestinal endoscopy for evaluation of dyspepsia without gastric cancer or any family history. All subjects were endoscopically examined. Results: The overall prevalence of Helicobacter pylori was 77.7% in the cancer relatives and in 75.7% in the control group. Chronic gastritis was found in 90.4% vs. 81.1% (P<0.001). Regarding histological findings, 37(7.4%) of the study group had atrophy vs. 12(1.7%) in the control group (P<0.001), while no difference was observed for intestinal metaplasia (20.3%vs. 21.6%, P=0.58). Dysplasia were shown in 4% of cancer relatives but only 0.4% of the control group (P<0.001). There was no gender specificity. Conclusions: Findings of our study point to great importance of screening in relatives of gastric cancer patients in Iran.

Muir-Torre syndrome is defined by concurrent or sequential development of internal malignancy and sebaceous neoplasm or multiple keratoacanthomas. Muir-Torre syndrome is very rare, with only 205 cases reported in the literature. We reported a patient with Muir-Torre syndrome with three internal malignancies. A 64-year-old patient with a history of breast cancer, stomach cancer and colon cancer visited our department for treatment of the skin lesion that occurred five years before on the left cheek. The lesion was excised completely with a resection margin of 1 cm, followed by full-thickness skin graft from left postauricular area for reconstruction. Histopathology revealed a $0.2{\times}0.2{\times}0.1cm$ sized sebaceous carcinoma with 4 mm safety margin. The skin graft was well taken within 7 days after surgery and the patient was discharged to outpatient follow-up. There was no complication related with surgery. Muir-Torre syndrome is very rare, as are sebaceous gland tumors. So if a cancer of the sebaceous gland is diagnosed, screening workup for internal malignancy is recommended. Because of its good prognosis, surgical removal of primary or metastatic cancers may be curative and should be attempted where possible.

Background: Cancer is a leading cause of death throughout the world. Increasing life expectancy and aging population are important factors for increasing cancer incidences in developing countries. National programs are essential for prevention and control of cancer in any society. This study aimed to investigate cancer epidemiology and trends in the province of Hamadan, located in Northwest Iran. Materials and Methods: This analytical study was carried out based on cancer registry data from 2004 to 2009 in the province of Hamadan, analyzed using STATA (version 12) software for descriptive tests and Join point 4.1.1.1 software for analytical tests. Results: There were 7,767 registered cases of cancer during the 6 years studied. Of the total cases registered, 59.1% (4,592 cases) involved men and 40.9% (3,175 cases) occurred in women. Age-standardized incidence rates (ASR) increased from 72.9 to 132.0 in males and 48.2 to 115.0 in females during the 6 years of the study (p<0.001). The most common cancers were skin, stomach, breast, bladder, and leukemia. In women, teh most common were breast, skin, stomach, colorectal, and leukemia, in that order, and in men skin, stomach, bladder, leukemia, and prostate cancers. Conclusions: The cancer incidence is greater in men that women in this region but with increasing trends in both sexes. Planning regarding education in prevention of exposure to risk factors and control strategies is required to decrease the incident cases. Screening programs for common cancers in older age groups might be helpful to reduce the disease impact.

Purpose: This study aimed to analyze the effect of screening by using endoscopy on the diagnosis and treatment of gastric cancer. Materials and Methods: The clinicopathologic characteristics of gastric cancer were compared in individuals who underwent an endoscopy because of symptoms (non-screening group) or for screening purposes (screening group). The distributions of gastric cancer stages and treatment modalities in 2006 and 2011 were compared. Results: The proportion of patients in the screening group increased from 45.1% in 2006 to 65.4% in 2011 (P<0.001). The proportion of stage I cancers in the entire patient sample also increased (from 60.5% in 2006 to 70.6% in 2011; P=0.029). In 2011, the percentages of patients with cancer stages I, II, III, and IV were 79.9%, 8.2%, 10.9%, and 1.1%, respectively, in the screening group, and 47.9%, 10.8%, 29.8%, and 11.5%, respectively, in the non-screening group. The proportion of laparoscopic and robotic surgeries increased from 9.6% in 2006 to 48.3% in 2011 (P<0.001), and endoscopic submucosal dissection increased from 9.8% in 2006 to 19.1% 2011 (P<0.001). Conclusions: The proportion of patients diagnosed with gastric cancer by using the screening program increased between 2006 and 2011. This increase was associated with a high proportion of early-stage cancer diagnoses and increased use of minimally invasive treatments.

Laparoscopic gastrectomy was begun in 1995 in Korea. But, there was 4 years gap to reactivate in 1999. High incidence of gastric cancer and increasing proportion of early cancer through national screening program along with huge effort and enthusiasm of laparoscopic gastric surgeon, and active academic exchange with Japanese doctors contributed development of laparoscopic gastrectomy in Korea. Study group activity of Korean Laparoscopic Gastrointestinal Surgery Study (KLASS) group and Collaborative Action for Gastric Cancer (COACT) group were paramount to evoke large scale multicenter clinical study and various well performed clinical studies. This review encompasses mainly international publications about this area so far in Korea.

배경 및 목적: 우리나라에서는 위암 검진을 수행하고 있으며, 조기위암의 비중이 증가되고 있으나, 위암 검진 지침에 따른 구체적인 효과에 대해서는 많은 보고는 없다. 이에 최근 위암 검진의 현황과 조기위암과 진행성 위암의 년도별 발생률 변화의 추이 등 여러 검진관련 자료 분석을 통한 국가 위암 검진의 효과에 대하여 알아보고자 본 연구를 진행하였다. 방법: 본 연구는 2009년부터 2015년까지 위암, 조기위암, 진행성 위암 그리고 그 외로 청구된 이력들을 조사하였다. KCD-6 코드가 2011년부터 적용되었으며, 질병청구 시 상병 코드가 KCD-6로 개정되면서 위암을 조기위암과 진행성 위암으로 코드를 세분화하였다. 국가건강검진에서 40세 이상 대상자에 대해 2년에 한 번씩 시행되는 위암 검사에 대한 효율성 평가를 위해 위암으로 등록되기 이전에 검진 경험 유, 무에 대한 분석을 진행하였으며 또한 위암 검진의 효과에 대해 성별로 구분지어 분석하였다. 결과: 2009-2015년 위암으로 등록된 환자 중 이전에 위암 검진 경험이 있었던 대상자가 전체 위암 대상자 중 74%로 검진 무경험자에 비해 월등히 높았다. 그 중 검진 이후 1년 이내에 위암으로 진단된 사람이 28.8%, 2년 이내 15.5%를 차지하였다. 암 진단 당시에 위암 진행 정도를 확인해 본 결과 검진 이후 1년 이내 발생한 경우, 조기위암은 21.1%, 진행성 위암 14.6% 로 나타났고, 검진 이후 2년 이내 조기위암은 31.5%, 진행성 위암 17.5%로 나타났다. 검진 무경험자들의 암 유형별 발생 현황을 보면 같은 기간 검진 경험자에 비해 조기위암은 15.1%, 진행성 위암은 25.3%로 진행성 위암의 비율이 높았다. 성별에 따른 분석 결과, 남자의 경우 검진을 통해 암 발생을 확인한 경우가 76% 여자의 경우 암 발생을 확인한 경우가 70.2%로 나타났다. 남녀 모두에서 검진 경험자가 검진 무경험자에 비해 조기위암으로 진단되는 비율이 높았다. 결론: 최근 위암 국가검진 자료가 포함된 이번 분석을 통하여 위암 검진의 병기 이전 효과를 확인할 수 있었다. 그러나 2년 이내 위암 검진 음성인 군에서 양성으로 진단된 환자가 상대적으로 적지 않았다. 따라서 위암 검진의 효과와 위해를 평가하고, 위암 검진의 질을 향상시키기 위한 더 많은 관련 연구가 필요하다.

Osteoporosis in gastric cancer patients is often overlooked or even neglected despite its high prevalence in these patients. Considering that old age, malnutrition, chronic disease, chemotherapy, decreased body mass index and gastrectomy are independent risk factors for osteoporosis, it is reasonable that the prevalence of osteoporosis in gastric cancer patients would be high. Many surviving patients suffer from back pain and pathological fractures, which are related to osteoporosis. Fractures have obvious associated morbidities, negative impact on quality of life, and impose both direct and indirect costs. In the era of a >55.6% 5-year survival rate of gastric cancer and increased longevity in gastric cancer patients, it is very important to eliminate common sequelae such as osteoporosis. Fortunately, the diagnosis of osteoporosis is well established and many therapeutic agents have been shown to be effective and safe not only in postmenopausal females but also in elderly males. Recently, effective treatments of gastric cancer patients with osteoporosis using bisphosphonates, which are commonly used in postmenopausal woman, were reported.

Hereditary syndromes cause approximately 5 to 10% of overall cancer cases. Cancer related with genetic syndromes are found elsewhere, including stomach, breast, colorectum, ovary, brain and so on. Because hereditary cancers are due to germline mutations, these patients have unique clinical features distinct from sporadic cancer. Generally these features include (i) early age-of onset of cancer, (ii) frequent association with synchronous or metachronous tumors, (iii) frequent bilateral involvement in paired organs (iv) frequent association with other site tumors or characteristic clinical manifestation specific to each genetic syndrome. Due to these differences, the management strategy for patients with hereditary cancer is quite different from that for sporadic cancer. Additionally, there are important screening and surveillance implications for family members. Genetic counselling is prerequisite to these families for risk assessment by pedigree analysis, and guidance to clinical or genetic testing. The genes responsible for these syndromes has recently identified, as a result, genetic testing has become important determining factor in clinical decisions.
