Background: Dedicated, organ-specific screening clinics have been shown to significantly reduce cancer morbidity and mortality.

Objectives: To establish a dedicated clinic for Clalit Health Service patients at high risk for hereditary gastrointestinal cancer and to provide them with clinical and genetic counseling, diagnostic screening and follow–up.

Results: During the 3 years of the clinic's activity, 634 high risk families, including 3804 at-risk relatives, were evaluated. The most common conditions were hereditary colorectal syndromes, Lynch syndrome (n=259), undefined young-onset or familial colorectal cancer (n=214), familial adenomatous polyposis (n=55), and others (n=106). They entered follow-up protocols and 52 underwent surgical procedures.

Conclusions: Consistent public and professional education is needed to increase awareness of hereditary colorectal cancer and the possibility of family screening, early diagnosis and therapy. The public health services – i.e., the four health management organizations – should provide genetic testing for these patients who, at present, are required to pay for almost all of these available but costly tests. Dedicated colorectal surgical units are needed to provide the specialized therapeutic procedures needed by patients with familial colorectal cancer. Our future plans include adding psychosocial support for these at-risk patients and their families as well as preventive lifestyle and dietary intervention. 

Background: Colonoscopy is the gold standard procedure for screening for colorectal cancer and surveillance after polypectomy or colorectal cancer surgery, for diagnosis in symptomatic patients and patients with fecal occult blood, and for screening in the high risk population. The adherence of referring physicians to the accepted recommendations can prevent long waiting lists for colonoscopy and save lives, costs and resources.

Objectives: To evaluate the knowledge of primary care physicians and gastroenterologists in Israel about current guidelines for colonoscopy screening and surveillance.

Methods: A 10-item questionnaire on proper follow-up colonoscopy for surveillance after polypectomy and screening for colorectal cancer in various clinical and epidemiological situations was administered to 100 expert gastroenterologists and 100 primary care physicians at a professional meeting. Answers were evaluated for each group of physicians and compared using the chi-square test.

Results: The compliance rate was 45% for the gastroenterologists and 80% for the primary care physicians. The rate of correct answers to the specific items ranged from 18.7% to 93.75% for the gastroenterologists and from 6.2% to 58.5% for the primary care physicians (P < 0.001 for almost every item).

Conclusions: The knowledge of physicians regarding the screening and surveillance of colorectal cancer needs to be improved.
