Incidence rates of cutaneous squamous cell carcinoma (SCC) are increasing in many countries. To estimate detailed trends of SCC incidence rates in the population of Akita Prefecture as the forerunner of super-aged societies, we conducted a retrospective analysis of patients diagnosed with SCC between 2007 and 2016 in Akita University Hospital. The crude SCC incidence rate increased rapidly between 2007 and 2016 from 2.5 to 10.0/100 000 people. Remarkably, the age-specific incidence rate of people aged 80 years or over increased between 2007 and 2016 from 14.7 to 51.6/100 000 people, suggesting that SCC incidence rates increase possibly due to not only the increased number of aged people but also because of unidentified cancer-prone environments. When the findings of the present study are generalized to other regions entering the era of super-aging, it is clear that we need to prepare for the economic disease burden together with careful monitoring to confirm future trends for SCC.
在许多国家，皮肤鳞状细胞癌 (SCC) 的发病率正在上升。为了估计超级老龄化社会先驱——秋田县人群中 SCC 发病率的详细趋势，我们对 2007 年至 2016 年在秋田大学医院诊断为 SCC 的患者进行了回顾性分析。2007 年至 2016 年期间，SCC 的粗发病率从 2.5/100000 人迅速上升至 10.0/100000 人。值得注意的是，2007 年至 2016 年期间，80 岁及以上人群的特定年龄发病率从 14.7/100000 人上升至 51.6/100000 人，这表明 SCC 发病率的增加可能不仅是由于老年人口的增加，还可能是由于未识别的致癌环境。当本研究的结果推广到其他进入超级老龄化时代的地区时，很明显，我们需要共同准备应对经济疾病负担，并进行仔细监测以确认 SCC 的未来趋势。
