Lifetime Health Maintenance Program(LHMP) or Koreans is the Korean guide to clinical preventive services which include screening for chronic diseases, counseling and immunization. The Korean Task Force on the LHMP vigorously reviews evidence for interventions to prevent over 50 different illnesses and conditions which are important in Korea. The problems addressed in this program are common ones seen every day by primary care physicians in Korea: cardiovascular, infectious diseases, gastrointestinal and endocrine diseases, cancers, alcohol and smoking, and many others. Primary care clinicians have a key role in screening for many of these problems and imunizing against others Of equal importance, however, is the clinician's role in counseling patients to change unhealthful behaviors related to diet, smoking, exercise, injuries, and sexually transmitted diseases The recommendations are grouped by age, sex, and other risk factors.

Double primary cancer is a rare disease in which two cancers occur in an individual independently. As prolonged survival of patients with malignant tumors is expected in the future due to advances in methods of treatment, the chance of double primary cancer will be increased. We experienced one case of double primary cancer which was developed in esophagus and chest wall. A 72 year-old male visited our hospital complaining of epigastric discomfort and right chest wall mass. We studied esophagus, chest wall, and other organs including gastrointestinal tract by various methods to exclude the cancer of other sites and could diagnose squamous cell carcinoma of mid-esophagus and adenocarcinoma of chest wall. The patient underwent esophagogastrostomy following esophagectomy and wide-resection of chest wall tumor. The postoperative course was uneventful.

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.

Chemotherapy and surgical resection are the mainstay of cancer treatment. Particularly for chemotherapy, although it is effective method to care, sometimes cure various cancers, there are many different status of cancer not being controlled by chemotherapy such as recurrence and resistance to chemotherapy. In order to overcome those difficulties during cancer therapy, immunotherapy targeting immune cells and immune associated factors to enhance cancer immunity has been highlighted. Innate immunity plays important roles on initial stage of cancer immunity that are detecting, killing cancer cells and initiating adaptive immunity for cancer. So many basic and clinical studies to manage innate immunity for cancer therapy have been going on, and most of them were to stimulate innate immune cells including dendritic cell, macrophage, monocyte, and natural killer cell in various ways. They showed promising results but still there are many things to be resolved before clinical application. Herein, I review the role of innate immune cells and therapeutic trials for colorectal cancer.

MicroRNA (miRNA) dysregulations are associated with various types of human cancers, and miRNAs can function as tumor suppressors and oncogenes. Emerging evidence has shown that miRNA pathway is also altered during colorectal tumorigenesis. The detection of cancer-related miRNAs in stool samples may become useful diagnostic marker for colorectal cancer, because miRNAs in stool samples has high stability, and maintains a high portion of its original level. Recent studies reported that stool-based miRNAs can offer more sensitivity and specificity than currently used stool-based screening methods for CRC. In addition, unlike fecal occult blood test, sampling on consecutive dates and special dietary restrictions are not required. In this review, the authors discuss stool-based miRNA for the early diagnosis of CRC and perspectives on future application.

Pancreatic cancer is one of the most aggressive cancers, and it is expected to become the second-leading cause of cancer-related death in the United States by 2030. Its 5-year survival rate is <10% and approximately 15% of cases are eligible for surgical treatment during diagnosis. Furthermore, the risk of recurrence within 1 year postoperative is as high as 50%. Therefore, chemotherapy plays a crucial role in pancreatic cancer treatment. Survival rates are speculated to have improved since the introduction of FOLFIRINOX and gemcitabine/nab-paclitaxel combination therapy for metastatic pancreatic cancer in the 2010s. Additionally, the implementation of both neoadjuvant and adjuvant treatments in resectable and borderline resectable pancreatic cancer caused better outcomes compared to upfront surgery. Recently, not only have these medications advanced in development, but so have PARP inhibitors and KRAS inhibitors, contributing to the treatment landscape. This study aimed to explore the latest insights into chemotherapy for pancreatic cancer.

Pancreatic cancers have a poor prognosis, and their incident rates have risen. Endoscopic ultrasonography (EUS) is an efficient and reliable diagnostic modality for pancreatic lesions, providing high spatial resolution. However, while EUS helps to detect minor pancreatic lesions, nearly all solid pancreatic lesions are hypoechoic, which creates difficulty in making differential diagnoses of pancreatic lesions. When diagnosing pancreatic lesions, the performance of image-enhanced EUS techniques is essential, such as EUS elastography or contrast-enhanced harmonic EUS (CH-EUS). CH-EUS diagnosis is based on assessing the vascularity of lesions, whereas tissue elasticity is measured via EUS elastography. Elastography is either strain or shear-wave, depending on the different mechanical properties being evaluated. The usefulness of enhanced EUS techniques is demonstrated in this review for the differential diagnosis of pancreatic lesions, including solid and cystic lesions, and pancreatic cancer staging.

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.

Endoscopic submucosal dissection (ESD) is the standard treatment method for esophageal, gastric, and colorectal cancers. However, it has not been standardized for duodenal lesions because of its high complication rates. Recently, minimally invasive and simple methods such as cold snare polypectomy and underwater endoscopic mucosal resection have been utilized more for superficial nonampullary duodenal epithelial tumors (SNADETs). Although the rate of complications associated with duodenal ESD has been gradually decreasing because of technical advancements, performing ESD for all SNADETs is unnecessary. As such, the appropriate treatment plan for SNADETs should be chosen according to the lesion type, patient condition, and endoscopist's skill.

This study examined the incidence rates of cancer cases (averages for 2006-2010) and relationships with environmental radioactivity levels. Soil and water samples were collected from provincial and district centers of Van city and the outdoor gamma doses were determined using a portable gamma scintillation detector. Gross alpha and beta, (226)Ra, (232)Th, and (40)K activities were measured in both tap water and soil samples. Although high rates of stomach and esophagus cancers have been reported previously in Van the underlying reasons have not hitherto been defined. Incidences of cancers were highest in the Gurpmar (326.0) and Ozalp (377.1) counties (p<0.001). As to the results of the gross alpha and gross beta radioactivity measurements in the drinking water, these two counties also had high beta radionuclide levels: Gurpmar ($140mBq/dm^3$) and Ozalp ($206mBq/dm^3$). Even if within the normal range, a relation between the higher rate of the incidence of stomach and esophagus cancers with that of the higher rate of beta radionuclide activity was clear. On Spearman correlation analysis, the relation between higher beta radionuclide levels and cancer incidence was found to be statistically significant (p<0.01). According to the results of the analysis, Van residents receive an average 1.86 mSv/y annual dose from outdoor gamma radiation, ingestion of radionuclides in the drinking water, and indoor $^{222}Rn$ activity. Moreover, gross alpha and beta activities were found to be extremely high in all of the lakes around the city of Van, Turkey. Further investigations with long-term detailed environmental radiation measurements are needed regarding the relationship between cancer cases and environmental radioactivity in the city of Van.
