  • Background: Cancer is becoming the most important public health burden around the globe. As per the GLOBOCAN 2008 estimates, about 12.7 million cancer cases and 7.6 million cancer deaths were estimated to have occurred in 2008. The burden of cancer cases for India in the year 2020 is calculated to be 1,148,757 (male 534,353; female 614,404) compared to 979,786 in 2010. The pattern of cancer incidence is varying among geographical regions, esophageal cancer for example being high in China, lung cancer in USA, and gallbladder cancer in Chile. The question remains why? Is it due to the diversity in genome pool, food habits, risk factor association and role of genetic susceptibility or some other factors associated with it? In India, the North East (NE)-India region is seeing a marked increase in cancer incidence and deaths, with a very different cancer incidence pattern compared to mainland India. The genome pool of the region is also quite distinct from the rest of India. Northeastern tribes are quite distinct from other groups; they are more closely related to East Asians than to other Indians. In this paper an attempt was made to see whether there is any similarity among the pattern of cancer incidence cases for different sites of NE-India region to South or East-Asia. Materials and Methods: Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA), Pearson Correlation coefficient test was assessed to evaluate the linkage of North-East India region to other regions. A p value <0.05 was considered as statistically significant. Results: The results clearly shows that there are similarities in occurrence of cancer incidence patterns for various cancer sites of NE-India with South and East-Asian regions, which may lead to the conclusion that there might be a genetic linkage between these regions.

  • 본 연구에서는 전라북도 지역암등록본부로부터 2001년부터 2010년까지 10년간 수집된 암등록 자료를 토대로 전라북도 지역의 성별, 연령군별, 호발암별 암발생률 비교 분석과 변동 추이를 살펴보았으며, 또한 국제암연구소에서 제시하는 평가 지표를 기반으로 암등록자료의 질적 수준을 평가하였다. 전라북도 지역의 암발생률 통계 및 암등록 자료의 질 관리 지표는 전북지역암센터의 지역암등록본부로부터 수집되었다. 모든 암들에 대한 성별조발생율(CR)과 연령표준화발생률(ASR)의 10년간 추이를 살펴보았으며, 남녀 5대 호발암에 대한 ASR의 10년간 추이를 분석하였다. 또한 전라북도 지역암등록본부의 암등록 자료에 대한 년도별, 성별, 호발암별 질적 수준을 평가하기 위해 충실도와 타당도를 분석하였다. 충실도 평가를 위해 사용된 지표는 사망/발생비(MI%)와 연령별 발생률 곡선이며, 타당도 평가를 위해 사용된 지표는 연령 미상률(UNK%), 현미경적 확진율(MV%) 그리고 사망진단서에서만 확인가능한 환자의 분율(DCO%)이다. 암 발생률의 10년간 변동 추이는 joinpoint 회귀분석 도구를 이용하였으며, 해당 기간에 대한 연평균 암발생 변화율(AAPC)을 측정하였다. 10년간 전라북도 지역에서의 남성 호발암 순위는 위암이 22.2%로 가장 높았으며, 다음으로 폐암 16.6%, 대장암 12.8%, 간암 12.3%, 전립샘암 6.2% 순으로 나타났다. 여성에서는 갑상샘암이 17.8%로 가장 높았고, 위암 14.7%, 유방암 11.6%, 대장암 11.5%, 폐암 7.7% 순으로 나타났다. 10년 동안 모든 암들에 대한 연령표준화발생률(ASR)을 살펴보면 전체적으로 36.5% 증가하였다. 성별에 따른 ASR 증가율을 살펴보면 남성에서는 13.7%, 여성에서는 68% 증가하였다. 성별 호발암의 연간 변동 추이를 살펴보면 남성의 위암, 폐암, 간암 발생률은 각각 연평균 1.8%, 0.8%, 3.2% 감소하는 추세를 보이고 있으나, 대장암과 전립샘암은 각각 4.9%, 15.1% 증가하는 추세를 보였다. 여성에서는 5대 호발암중 유일하게 위암이 연평균 0.6% 감소하는 추세를 보였으나, 유방암, 대장암, 폐암은 각각 연평균 5.6%, 2.7%, 2.2% 증가 추세를 보였고, 특히 갑상샘암은 연평균 29.6%의 급격한 증가 추세를 보였다. 암등록 자료의 질적 수준 평가에서 충실도 평가 지표인 MI%는 남성에서 2001년 39.4%에서 2010년 32.4%로 낮아졌고, 여성의 경우 2001년 32.2%에서 2010년 23.5%로 낮아져 적정한 수준을 유지하였다. 타당도 평가 지표인 UNK%는 전라북도 지역에서 10년간 남녀 모두 0%로 나타났으며, DCO%는 남성에서 2001년 5.6%에서 2010년 1.3%로 낮아졌고, 여성에서는 2001년 6.1%에서 2010년 1.8%로 낮아져 암등록 자료의 정확성이 향상되었다. MV%는 남성의 경우 2001년 76.3%에서 2010년 88.5%로 증가하였고, 여성의 경우 2001년 78.4%에서 2010년 90.8%로 증가하여, 남녀 모두에서 암진단의 정확성이 높아진 것으로 확인되었다. 전라북도의 10년간 암발생률 추이를 분석한 결과 남성보다 여성에서 암발생률이 증가하고 있으며, 특히 남성에서는 대장암과 전립샘암이, 여성에서는 갑상샘암과 유방암이 증가하고 있음을 확인하였다. 또한 전라북도 지역암등록본부의 암등록 자료의 질관리 수준이 향상되고 있음을 확인하였다. 향후 연구에서는 대도시지역 또는 전라북도와 유사한 다른 지역과의 지역별, 연령별 호발암 및 암발생률 추이를 심층적이고 다각도로 비교 분석하여 향후 국가 차원의 암관리 대책 마련과 암 조기검진사업 추진 등의 보건 정책을 수립하는데 이와 같은 통계 자료가 반영될 수 있도록 해야 할 것이다.

  • The incidence of gastric cancer has steadily declined and the overall mortality rate from gastric cancer has similarly decreased. However, compared to other malignancies, the quality of life and life expectancy remain relatively poor in patients with gastric cancer. For gastric cancers, surgical resection is the main treatment, but the optimal therapeutic strategy for locally advanced gastric cancer remains undefined. For many patients with gastric cancer, not only chemotherapy but also radiotherapy plays a crucial role in both the curative and palliative settings. In this article, we review the evidence for the different treatment paradigms with a particular focus on the role of radiotherapy.

  • Purpose: Delayed gastric emptying usually manifests as gastric food retention. This study aimed to evaluate the incidence of gastric food retention after distal gastrectomy with gastrojejunostomy in gastric cancer patients and identify the risk factors for its development. Materials and Methods: We retrospectively enrolled 245 patients who underwent distal gastrectomy with gastrojejunostomy for gastric cancer at Boramae Medical Center between March 2017 and December 2019. We analyzed the presence of gastric food residue via computed tomography (CT) scans at 3 and 12 months postoperatively and analyzed the risk factors that may influence the development of gastric food retention. Results: CT scans were performed on 235 patients at 3 months and on 217 patients at 12 months postoperatively. In the group that received closure of Petersen's space, the incidence of gastric food retention was significantly low as per the 3- and 12-month postoperative follow-up CT scans (P=0.028 and 0.003, respectively). In addition, hypertension was related to gastric food retention as per the 12-month postoperative follow-up CT scans (P=0.011). No other factors were related to the development of gastric food retention. In the multivariate analysis, non-closure of Petersen's space (hazard ratio [HR], 2.54; 95% confidence interval [CI], 1.20-5.38; P=0.010) was the only significant risk factor for gastric food retention at 3 months postoperatively, while non-closure of Petersen's space (HR, 2.81; 95% CI, 1.40-5.64; P=0.004) and hypertension (HR, 2.30; 95% CI, 1.14-4.63; P=0.020) were both significant risk factors for gastric food retention at 12 months postoperatively. Conclusions: Closure of Petersen's space has an effect on decrease the incidence of gastric food retention after distal gastrectomy with gastrojejunostomy in gastric cancer patients.

  • Background: According to increase in elderly populations, and change in lifestyle and cancer-causing behavior, the global burden of cancer is increasing. For prevention and control of disease, knowledge of population statistics of cancers and their trends is essential. This study aimed to investigate the epidemiology and trends of cancer in the province of Kerman: southeast of Iran. Materials and Methods: This analytical and cross-sectional study was carried out based on cancer registry data at the Disease Management Center of the Health Ministry from 2004 to 2009 in the province of Kerman in Iran. Common cancers were defined as the number of reported cases and standardized incidence rates. To compute the annual percentage change (APC), joinpoint 4.1.1.1 software was applied. Results: Of 10,595 registered cases, 45.3% (4802 cases) were in women and 56.7% (5,793 cases) occurred in men. The standardized incidence rates for both females and males were increasing during the six years studied. The most common cancers in both sexes during six years of studied were skin (13.4%), breast (9.35%), bladder (7.8%), stomach (7.45%), leukemia (7.05%), colorectal(5.57%), lung(4.92%), trachea(3.51%) and prostate(2.48%). Conclusions: Our findings revealed that the cancer incidence is demonstrating increasing trends in both sexes in the province of Kerman. This may be because of changes in lifestyle, increasing exposure to risk factors for cancer and increase of life expectancy. If this is the case, increasing public awareness of cancer risk factors is a high priority, together with introduction of large-scale screening techniques.

  • Purpose: To evaluate the incidence, clinicopathological characteristics, treatment outcomes, prognostic factors, and survival of gastric cancer patients with bone metastases. Materials and Methods: Of 4,617 gastric cancer patients who were treated between 2001 and 2013, 176 patients with bone metastases were analyzed. Results: The incidence of bone metastasis was 3.8%. The most common histopathological subtype was adenocarcinoma (79%) with poor differentiation (60.8%). The median interval from the diagnosis to bone metastasis was 11 months. The median survival time after bone metastasis was 5.4 months. Factors that were associated with longer median survival times included the following: isolated bone metastasis (P=0.004), well-differentiated tumors (P=0.002), palliative chemotherapy (P=0.003), zoledronic acid treatment (P<0.001), no smoking history (P=0.007), and no metastatic gastric cancer at the time of diagnosis (P=0.01). On the other hand, high levels of lactate dehydrogenase (LDH) (hazard ratio [HR]: 1.86; P=0.015), carcinoembryonic antigen (CEA) (HR: 2.04; P=0.002), and carbohydrate antigen (CA) 19-9 (HR: 2.94; P<0.001) were associated with shorter survival times. In multivariate analysis, receiving zoledronic acid (P<0.001) and performance status (P=0.013) were independent prognostic factors. Conclusions: Smoking history, poor performance status, poorly differentiated adenocarcinoma, and high levels of LDH, CEA, and CA 19-9 were shown to be poor prognostic factors, while receiving chemotherapy and zoledronic acid were associated with prolonged survival in gastric cancer patients with bone metastases.

  • Gastric cancer is one of the leading causes of cancer-related deaths worldwide. The increased expression of cyclooxygenase (COX)-2 has been implicated in the development and progression of gastric cancers. A number of recent studies have been published evaluating the chemopreventive effect of aspirin and non steroidal anti inflammatory drungs (NSAIDs) against gastric cancer. Aspirin and NSAIDs use may reduce the risk of gastric cancer incidence and death, whereas other studies have reported contradictory results. Therefore, further study should be needed to clarify the role of aspirin and NSAIDs in the chemoprevention of gastric cancer.

  • In Korea, proximal gastrectomy has recently attracted attention as a better choice of function-preserving surgery for proximal early gastric cancer than total gastrectomy. Of the various strategies to overcome reflux symptoms from remnant stomach, double tract reconstruction not only reduces the incidence of anastomosis-related complications, but is also sufficiently reproducible as a laparoscopic procedure. Catching up with the recent rise of single-port laparoscopic surgeries, we performed a pure single-port laparoscopic proximal gastrectomy with DTR. This procedure was designed by merging the function-preserving concept of proximal gastrectomy with single-port laparoscopic total gastrectomy.

  • Objective: To explore the prevalence of malignant tumors in the adult population through 2003-2014 in parts of the Aral Sea region: a zone of ecological disaster, a zone of ecological crisis and a zone of precritical conditions. Methods: The long-time average annual levels of cancer morbidity stratified by zones of the Aral Sea region and trends of long-time average annual incidence indicators of malignant tumors were identified. Leading cancer localizations in the adult population was established and associations between cancer incidence and environmental pollution were analyzed. In addition, associations between individual risk factors and cancer incidence in the adult population was established. Correlations between a hazard index and the cancer incidence in the adult population were calculated. Results: In all three Aral Sea regions, as well as in Zhanaarkinskii district, leading cancer in adult population was esophageal, stomach, tracheal, lung, hepatobiliary, and breast. Long-time average annual levels of cancer morbidity in adult population living in the Aral sea region is 1.5 times higher comparing to the control region. In particular, long-time average annual levels of cancer morbidity in adult population living in the zone of ecological disaster was 57.2% higher, in the zone of ecological crisis - 61.9% higher, and in the zone of precritical condition - 16.8% higher. Long-time average annual levels in the adult population of the Aral Sea region significantly exceeded control levels for brain and central nervous system cancer, cancer of bone and articular cartilage, and thyroid cancer. Conclusion: It has was established that the total cancer morbidity depended on the total hazard index associated with the inhalation of nickel and the combined cadmium intake (r=0.8).
