Determining cancer incidence and mortality is a key factor in the implementation of health policies and cancer prevention strategies. This report aims to describe the trends of cancer incidence in a single referral oncology department from the Marrakech region (Morocco). . All new cancer cases of age ≥ 15 years registered at the Medical Oncology department of Mohammed VI University Hospital of Marrakesh between January 1, 2012, and December 31, 2019, were included. Central nervous system (CNS) cancers, tumors of hematopoietic and lymphoid tissues, and thyroid cancers for which chemotherapy was not indicated or was managed in other cancer-specialized departments were excluded from the analysis. Manual data collection from printed archived medical records of the study population was performed. Descriptive statistics were analyzed using R software and Joinpoint Regression Program.
A total of 15648 new cancer cases were analyzed. Missing data ( = 1822) accounted for 11.64%, and 4.1% ( = 652) were excluded. The final statistical analysis and registration included 13174 cases. The median age at diagnosis is 54 years for females and 61 years for males. Female patients outnumbered males with a ratio of 1.58 among all age groups except those aged ≥75 y. The age-standardized incidence rate (ASIR) for all sites was 68,0 per 100.000 person-years, which has increased with an annual percent change (APC) of 10.61%. The five most common malignancies among males are lung, stomach, prostate, colic, and rectal cancers. Among females, the five most frequent cancers are breast, cervix, ovary, colon, and stomach.
The higher incidence observed in our results translates into a growing burden on the center and is expected to impact our ability to deliver cancer care. Epidemiological studies to identify risk factors and effective efforts are needed to further invest in cancer control and prevention plans.
确定癌症发病率和死亡率是实施卫生政策和癌症预防策略的关键因素。本报告旨在描述摩洛哥马拉喀什地区一家转诊肿瘤科室的癌症发病率趋势。纳入了2012年1月1日至2019年12月31日期间在马拉喀什穆罕默德六世大学医院医学肿瘤科登记的所有年龄≥15岁的新发癌症病例。分析排除了中枢神经系统（CNS）癌症、造血和淋巴组织肿瘤以及未指明化疗或在其他癌症专科科室治疗的甲状腺癌。通过人工从研究人群的纸质存档病历中收集数据。使用R软件和Joinpoint回归程序进行描述性统计分析。
共分析了15648例新发癌症病例。缺失数据（n = 1822）占11.64%，排除4.1%（n = 652）。最终统计分析和登记包括13174例病例。女性诊断时的中位年龄为54岁，男性为61岁。除75岁及以上年龄组外，所有年龄组中女性患者数量均多于男性，比例为1.58。所有部位的年龄标准化发病率（ASIR）为每10万人年68.0例，年变化百分比（APC）为10.61%，呈上升趋势。男性中五种最常见的恶性肿瘤是肺癌、胃癌、前列腺癌、结肠癌和直肠癌。女性中五种最常见的癌症是乳腺癌、宫颈癌、卵巢癌、结肠癌和胃癌。
我们的研究结果中观察到的较高发病率意味着该中心的负担日益加重，预计会影响我们提供癌症护理的能力。需要进行流行病学研究以确定风险因素，并做出有效努力，进一步投入癌症控制和预防计划。
