Abstract

Introduction

Stomach cancer is the tenth most common cancer in Northern Africa, accounting for 2.6% of all cancers. It is also the ninth leading cause of cancer death in both men and women, accounting for 3.5% of the total, with about 5 704 new cancer cases (3 371 men and 2 333 women) and 5 038 deaths from cancer in 2012 (GLOBOCAN 2012). The aim of this study is to assess the epidemiology of stomach cancer in Morocco.

Methods

This is a descriptive retrospective study of all patients treated for stomach cancer at Al Azhar Oncology Center in Rabat between 1994 and 2004.

Results

A total of 161 new cases were diagnosed with stomach cancer at Al Azhar Oncology Center, which was 18.5% of all new cases of gastrointestinal cancer and 2.3% of all cancers reported during the study period. Of these, 68.3% were men with a male-female ratio of 2.16. The average age at diagnosis of stomach cancer was 52.8 ± 13.3 years (range 4-83 years). The risk of developing the disease is associated with age, with 14.4% of cases diagnosed in patients younger than 40 years, 75% in those aged 40-69 years at the time of diagnosis and 10.7% in those aged 70 years and older. Among all diagnosed cases, 11.2% were diagnosed with metastatic disease and 22.4% died from the disease within one year of diagnosis, accounting for 3% of all cancer deaths.

Conclusion

The most recent estimates of stomach cancer incidence and mortality in the world reveal sharp differences between developed and developing countries possibly related to missed opportunities for early diagnosis and incomplete reporting of stomach cancer in Africa.
