Israel Medical Association Journal

Background: The Israel National Cancer Registry (INCR) was established in 1960. Reporting has been mandatory since 1982. All neoplasms of uncertain/unknown behavior, in situ and invasive malignancies (excluding basal and squamous cell carcinomas of the skin), and benign neoplasms of the brain and central nervous system (CNS) are reportable.

Objectives: To assess completeness and timeliness of the INCR for cases diagnosed or treated in 2005.

Methods: Abstractors identified cases of in situ and invasive malignancies and tumors of benign and uncertain behavior of the brain and CNS diagnosed or treated in 2005 in the files of medical records departments, pathology and cytology laboratories, and oncology and hematology institutes in 39 Israeli medical facilities. Cases were linked to the INCR database by national identity number. Duplicate cases, and those found to be non-reportable were excluded from analysis. Completeness was calculated as the percent of reportable cases identified by the survey that were present in the registry. Timeliness was calculated as the percent of reportable cases diagnosed in 2005, which were incorporated into the registry prior to 31 December 2007.

Results: The INCR’s completeness is estimated at 93.7% for all reportable diseases, 96.8% for invasive solid tumors, and 88.0% for hematopoietic tumors. Incident cases for the calendar year 2005 were less likely to be present in the registry database than those diagnosed prior to 2005.

Conclusions: Completeness and timeliness of the INCR are high and meet international guidelines. Fully automated reporting will likely improve the quality and timeliness of INCR data.

Background: Lung cancer is the most common cause of cancer-related death.

Objectives: To identify changing patterns of lung cancer and its histologic subtypes among different population groups in Israel over a 25 year period.

Methods: Primary lung cancers, all types and all stages, diagnosed during 1990–2014 were recorded in the Israel National Cancer Registry database. Demographic information was retrieved from the National Population Register. Age-standardized rates for the different subgroups were calculated for each year. Joinpoint software was used to analyze trends in incidence.

Results: We identified 42,672 lung cancer cases. The most common histology was adenocarcinoma (34%), followed by squamous cell carcinoma (19%), large cell/not-otherwise-specified (19%), other histologies (15%), and small cell lung cancer (11%). The adenocarcinoma incidence rose from 25.7% to 48.2% during the examined period. Large cell/not-otherwise-specified incidence peaked around 2005–2006 and declined after. Lung cancer incidence increased significantly for the population overall and specifically in Arab females, followed by Jewish females and by Arab males. Adenocarcinoma and small cell lung cancer increased in Jewish females and in Arab males. A younger age of diagnosis was seen in Arab compared to Jewish patients.

Conclusions: Jewish females and Arab males and females living in Israel demonstrated a constant increase in lung cancer incidence, mostly in adenocarcinoma and small cell lung cancer incidence. In addition, a younger age of diagnosis in Arabs was noted. Smoking reduction interventions and screening should be implemented in those populations.

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.
