Incidence, mortality and survival trends of smoking-related cancers in women in Setif, Algeria 1990-2009
Tobacco use is the leading preventable cause of disease and premature death, in Algeria and in the world. Our main objective is to estimate the impact of the tobacco on the women’s cancerous mortality and the morbidity in the Wilaya of Setif.
METHODS:
Incidence datas, were obtained from the population-based cancer registry of Setif, the sources of information of the cancer mortality were provided of the admission offices of the university hospital, the hospital public corporations and the center for the fight against cancer of Algiers, Constantine and the cancer registry, the information of the cancer survival were obtained by the incidence and the mortality datas, this file was coupled with the active follow-up of the vital status of the electoral lists and the registers of the civil status of the wilaya.
These cancer sites included in the monograph 100E of the international agency for research on cancer on 2012. The colorectal, the ovary, the breast cancers and the myelogenous leukemia, by adding them to the list of the smoking-related cancers with the significatvely relationship between tobacco use and the following cancers included in the 2004 monograph : oral cavity and pharyngeal, esophageal, stomach, liver, pancreatic, laryngeal, lung and bronchial, cervical cancers and kidney, urinary bladder cancers.
Our study consists in analyzing the cancer incidence trends in the period 1990-2009, cancer mortality in the period 2006-2009 and the cancer survival in the two periods 1996-2000 and 2001-2005 of the smoking-related cancers (SRC) among women in Setif, Algeria.
RESULTS:
from 1990 to 1996, we registered an age-adjusted incidence standardized rates (ASR) of the total cancers by 71,3 with an ASR of 34, 5 of the SRC per 100,000 women/year.
From 2005 to 2009, the ASR is 120, 3 of the total cancers with an ASR of 82, 1 of the SRC per 100,000 women/year.
A significantly increase incidence rates of the SRC for the both sexes, the annual percentage change was (+7, 2%) in women. The mortality of the SRC represents 47, 3% of the global mortality in women. On 2001-2005, cancer survival of the SRC is uniformly low; the cancer survival rates vary between the cancer survival rates in women vary between 52, 8% for breast cancer and 3, 3% for lung cancer.
CONCLUSIONS:
The change over time in the smoking related cancers incidence of females in Algeria can be explained fairly well by the increase in cumulative cigarette consumption at the national level. Prevention and tobacco control efforts are still needed to further reduce the burden of this disease.
