Background: The number of cancer survivors has been increasing worldwide and is now approximately 32.6 million and growing. Cancer survivors present a challenge to health care providers because of their higher susceptibility to long-term health outcomes related to their primary disease and treatment.

Objective: To report on the number of cancer survivors and incident cancer cases in the period 1960–2009 in Israel, in order to provide data on the scope of the challenge Israel’s health care funds face.

Methods: The Israel National Cancer Registry (INCR) database was used to identify new cancer cases diagnosed during the period 1960–2009. Lifetable analysis was used to assess changes in cumulative survival and population prevalence of cancer survivors throughout the 50 year study period.

Results: Almost 600,000 invasive cancer cases were diagnosed during the period 1960–2009 (overall absolute survival rate 54%). Within this time period, the number of new patients diagnosed with cancer increased fivefold and that of cancer survivors ninefold. The absolute survival of cancer patients and the prevalence of cancer survivors in the general population significantly increased with time from 34% and 0.5%, respectively (1960–1969), to 62% and 1.9%, respectively (2000–2009). Cumulative absolute survival for 5, 10 and 15 years following diagnosis increased with time as well.

Conclusions: The INCR database is useful to assess progress in the war against cancer. The growing numbers of cancer survivors in Israel present a challenge to the national health and social services system.

Objectives: To evaluate the extent and characteristics of CAM[1] use among cancer patients in northern Israel.

Methods: Telephone interviews were conducted with 2,176 newly registered cancer patients or their family members, at least 1 year following referral.

Results: The rates of CAM use varied significantly according to demographic characteristics and chemotherapy treatment, from 3% in the basically educated elderly group up to 69% of educated Israeli-born Jews younger than 70 years receiving chemotherapy. The overall rate of CAM use was 17%. The most influential factors determining CAM use were academic or high school education, chemotherapy treatment, Israel as country of birth, and age 41–50 years. All patients used CAM in addition to conventional therapies. Less than half of them reported it to their physicians. The most frequently used treatments were various chemical, biological, botanic and homeopathy remedies. Friends and relatives were the main recommenders of CAM. Most CAM users reported that they used CAM because they believed it “strengthens the immune system,” alleviates side effects of chemotherapy, improves quality of life and helps to overcome pain and stress, and 62% of them reported subjective beneficial effects.

Conclusions: A predicting module of CAM user patients was built, which may help physicians initiate conversations with their patients on CAM use. Expanding physicians' knowledge on CAM methods will encourage them to provide additional advice, promote the use of beneficial therapies, and inform patients about potentially harmful methods.
