During the period of 25 years from January 1978 through December 2002, a total of 808 colorectal cancer cases were operated on in Shirakawa Kosei General Hospital. The number of sugical resection cases came to 713 (ratio : 88.25%). Curative resection was performed on 593 cases (ratio : 73.4%). The total number of cases was broken down into 446 cases of cancer of the colon and 369 cases of cancer of the rectum (7 multiple cancer cases included). By sex, male cases numbered 329 and female cases 379. Clinically or histologically, many cases were diagnosed as stage IIIa or stage II cancer. The 5-year-survival rate for the resection cases was calculated at 67.2% and that for the cure resection cases, at 79.5%.

Krukenberg tumors are very rare. Its origin is difficult to define especially if its gross features mimic a primary ovarian cancer. We present a case of a 24-year-old Filipino female patient with metastatic mucinous ovarian adenocarcinoma of colonic origin that mimicked primary ovarian cancer and genitourinary tuberculosis. Surgery was done and histopathology revealed that the cancer was a metastatic mucinous adenocarcinoma of colonic origin. This case highlights the importance of differentiating between benign and malignant ovarian lesions as well as distinction between primary and metastatic ovarian neoplasms. Radiological imaging has an evolving role in diagnosis of different cancers, which may be improved through better clinical correlation and developing meaningful differential diagnosis while advancing to a more strategized algorithm in the diagnostic approach.

OBJECTIVE: To systematically review and assess the quality of guidelines on colorectal cancer screening worldwide to provide guidance for the development of high-quality colorectal cancer screening guidelines in mainland China. METHODS: CNKI, WanFang Data, VIP, SinoMed, PubMed, Embase, and Web of Science were systematically searched to identify guidelines on colorectal cancer screening from inception to Jun. 20th, 2018, and so were some websites and major search engines about the development of the guidelines from the existing literature (search date: Aug. 3rd, 2018). Two experienced reviewers independently examined these abstracts and then extracted information, and the Appraisal of Guidelines for Research and Evaluation II (AGREE II) were used to evaluate the methodological quality of these guidelines by four well trained reviewers. RESULTS: In this study, 46 guidelines published from 1994 to 2018 were finally included in our analysis from 10 countries and 5 regions, among which 5 were from mainland China. The quality of these guidelines was relatively high in domain 1 (scope and purpose) and domain 4 (clarity of presentation), and medium in domain 2 (stakeholder involvement). While in the other three domains (domain 3: rigour of development; domain 5: applicability; domain 6: editorial independence), the results were quite different among these guidelines. The quality of evidence-based guidelines (defined by the criteria based on World Health Organization guideline development handbook) was generally higher than that of the common guidelines. Existing guidelines from mainland China were not evidence-based guidelines, which were of low quality. CONCLUSION The colorectal cancer screening guidelines all over the world are generally large in number, low in quality, different in statements, and so are the guidelines in China. There are no evidence-based guidelines in mainland China, which cannot provide effective guidance for colorectal cancer screening, so we need to pay more attention to the establishment of guidelines with high quality and high credibility for colorectal cancer screening as well as for cancer screening based on the national condition, in order to provide reasonable guidance for practice in public health and improve the health conditions in our society.

BACKGROUND: Since the late 2000s, the number of anesthesia performed has increased yearly. However, there has not been research into the appropriate cost of anesthesia based on the difficulty of anesthesia performed, the number of medical personnel participated, and materials administered for anesthesia. The purpose of this study was to analyze the variations in anesthesia cost according to severity of their physical status and cancer stage in patients who had undertaken colorectal cancer surgeries. METHODS: In order to analyze the cost of anesthesia for colorectal cancer surgery, we used Electronic Data Interchange data from 2011 to 2012 of the three superior general hospitals in Seoul. Colorectal cancer codes were limited to seven codes included in the cancer screening statistics of the Health Insurance Review and Assessment Service. Based on these data, a frequency analysis and a multiple linear regression analysis were performed. RESULTS: There was no variation in the cost of anesthesia according to gender and age. However, the ASA physical status (PS) class and the cancer stage variables were confirmed to modify the anesthesia cost. CONCLUSIONS: These study imply that there is a difference in the technology used for anesthesia by medical personnel as well as the anesthesia related materials used according to the ASA PS and the cancer stage among patients having the same disease.

PURPOSE: This study was to develop and evaluate the clinical utility of a nursing educational program to reduce the cancer worry of colorectal cancer patients' family members (RCW-FM) in Korea. METHODS: The RCW-FM was developed based on several preliminary studies: an ethnographic and two quantitative studies to understand the educational needs among Korean colorectal cancer patients and their families. A one week clinical genetic educational course for clinical cancer nurses was implemented, and the RCW-FM led by cancer genetic nurses was constructed. A one group pretest-posttest design was implicated to evaluate the change of the family members' knowledge about colorectal cancer (KCR) and the level of the reduction of cancer worry (CWR). RESULTS: The mean score for KCR significantly increased from 11.75+/-1.28 to 13.87+/-1.13 (p<.05). The mean score of CWR was 4.25+/-.89. CONCLUSION: This new RCW-FM is a satisfactory educational program for reducing the cancer worry of the colorectal patients' family members. But it needs to provide more practical, specific information including a long term perspective, tailored specifically for what Korean families want to know. It should also incorporate the preventive guidelines recommended for high risk hereditary or familial colorectal cancer.

PURPOSE: This study aims to understand the worries that patients and families with a history of colorectal cancer experience. METHODS: From January 2011 through January 2013, in-depth interviews and observations were conducted on 3 colorectal patients and 8 family members with a family history of colorectal cancer. The data were analyzed using a micro-ethnographic research method. RESULTS: After colorectal cancer patients and families realized and concerned with their increased chance of getting cancer, Eventually this worry became a motivator causing them to adhere to cancer preventive behavior. Three types of cancer worries were identified: confrontation, uneasiness, and warning. Depending on the type of cancer risk, psychological responses and cancer preventive behavior were found to be varied according on the three types of cancer worries. Patients and families tried to change dietary habits and regulary exercise. To help ease their cancer worries, they started to search for information on colon cancers and attempted to follow recommendations. However, they found that neither detailed guidelines nor systematic management from health professionals existed for families with colon cancer patients. CONCLUSION: A cancer prevention nursing program needs to be developed based on the level of cancer risk and perceived cancer worries of clients.

Colorectal cancer (CRC) is the fourth most common cause of cancer death in China and the incidence has been increasing during the decades. It is reported to take decades for adenoma to transform to carcinoma, which is known as the main CRC pre-cancer lesion. It is important to carry out mass screening in the average risk populations to find the pre-cancer lesion and early cancer, which was the key approach to improve CRC survival. Fecal occult blood test and flexible sigmoidoscopy are the two CRC screening methods, which have been shown to reduce CRC mortality. It still needs to be confirmed in random clinical trials that the value of colonoscopy in CRC screening. In China, the most CRC screening experience was drawn from the works in Zhejiang province in 1970s. Consequently, the Chinese CRC treatment and guideline was founded to provide standard for the CRC screening project.

Colorectal cancer, which is the leading cancer in Singapore, can be prevented by increased use of screening and polypectomy. A range of screening strategies such as stool-based tests, flexible sigmoidoscopy, colonoscopy and computed tomography colonography are available, each with different strengths and limitations. Primary care physicians should discuss appropriate screening modalities with their patients, tailored to their individual needs. Physicians, patients and the government should work in partnership to improve uptake of colorectal cancer screening to reduce the morbidity and mortality from colorectal cancer.
