Abstract

Background

The burden of cancer is expected to nearly double in sub-Saharan Africa over the next 20 years. In Gabon, the primary population-based cancer registry to be established is located in the Grand Libreville. This study presents cancer incidence rates covering the first 5-year period of registration in this region.

Patients and methods

1,549 cancer cases were recorded among residents of the Grand Libreville between 2013 and 2017, 955 (61.6 %) women and 594 (38.3 %) males.

Results

The age standardized incidence rates (ASR) for all sites were 73.3 per 10⁵ in females and 47.7 per 10⁵ in males, rather similar from those observed in neighbouring countries of central Africa. Breast (ASR 19.0 per 10⁵) and cervical cancers (ASR 16.3 per 10⁵) accounted for half of female cancers. Prostate (ASR 12.0 per 10⁵), liver (ASR 5.1 per 10⁵) and colorectal cancers (ASR of 5.0 per 10⁵) accounted for 41.1 % of male cancers.

Conclusion

Breast and prostate cancers ranked first in females and males, respectively, even if the incidences appear much lower in comparison with other regional cancer registries rates, implying they may be underestimated. Cancers of the digestive organs were markedly more frequent in men than women, especially for liver, colorectal (and anus) and the mouth and pharynx. The incidence rates of these latter cancers are relatively similar to those of other registries of the central African region. These results may be of importance for implementing more adapted strategies in the battle against cancer.

加蓬大利伯维尔地区的癌症（2013-2017 年）。

背景：在未来 20 年内，撒哈拉以南非洲地区的癌症负担预计将增加近一倍。在加蓬，以人口为基础的癌症登记处主要设在大利伯维尔。本研究介绍了该地区第一个5年登记期的癌症发病率。患者和方法：2013年至2017年期间，大利伯维尔居民共记录了1549例癌症病例，其中女性955例（61.6%），男性594例（38.3%）：所有部位的年龄标准化发病率（ASR）分别为：女性73.3/105，男性47.7/105，与中部非洲邻国的发病率相当接近。乳腺癌（每 105 例中有 19.0 例）和宫颈癌（每 105 例中有 16.3 例）占女性癌症的一半。前列腺癌（每 105 人中 ASR 为 12.0）、肝癌（每 105 人中 ASR 为 5.1）和结肠直肠癌（每 105 人中 ASR 为 5.0）占男性癌症的 41.1%：结论：乳腺癌和前列腺癌分别在女性和男性中占首位，尽管与其他地区癌症登记率相比，这两种癌症的发病率似乎要低得多，这意味着它们可能被低估了。消化器官癌症在男性中的发病率明显高于女性，尤其是肝癌、结肠直肠癌（和肛门癌）以及口腔癌和咽喉癌。后几种癌症的发病率与中部非洲地区其他登记处的数据较为相似。这些结果对于在抗击癌症的斗争中实施更加适应的战略可能具有重要意义。
