Cancer incidence in Rabat, Morocco: 2006–2008

Abstract

Introduction

No population-based data of cancer incidence from Morocco have been published before. This is the first report of cancer incidence in Rabat from a population-based cancer registry for the period 2006–2008.

Materials and methods

The cancer registry collects data on all new cases of cancer diagnosed in the resident population of the Rabat area. Data collection is an active process involving visits by registry staff to all data sources, essentially hospitals, pathological laboratories, and private clinics in Rabat.

Results

A total of 2,473 new cases of cancer were registered among residents in Rabat during the period 2006–2008. The overall world age-standardised rate (ASR) for all sites combined was 136.6/100,000 for men and 114.5/100,000 for women. The most frequently diagnosed malignancies in males were lung cancer (19.0%, ASR 24.8/10 ⁵), followed by prostate cancer (15.5%, ASR 22.9/10 ⁵), colorectal cancer (8.8%, ASR 12.0/10 ⁵), bladder cancer (6.9%, ASR 9.7/10 ⁵), and non-Hodgkin’s lymphoma (NHL) (6.0%, ASR 8.2/10 ⁵). In females, the most frequently reported malignancies were breast cancer (39.9%, ASR 43.4/10 ⁵), followed by cervix uteri cancer (11.4%, ASR 13.0/10 ⁵), colorectal cancer (7.5%, ASR 9.0/10 ⁵), NHL (3.4, ASR 4.2/10 ⁵), and thyroid cancer (3.4%, ASR 3.9/10 ⁵).

Of all cancers, 2% are observed in childhood (0–14 years), and ~43% of them are malignant haemopathies.

Conclusion

The data reported by Rabat Cancer Registry indicate that cancers of the breast, cervix, uteri, and colon and rectum in females and the lung, prostate, and colon and rectum in men are major cancers in the population of Rabat. The Incidences observed are sometimes different from those observed in the neighbouring North African countries.
