Abstract

Background: Lung cancer (LC) is one of the most common neoplastic diseases and a leading cause of death in Saudi Arabia. Its incidence in Saudi Arabia has increased by more than 3% within two decades. Our study aimed to describe the epidemiological and genetic landscapes of LC in Al-Madinah city in Saudi Arabia. Methods: A retrospective analysis was conducted on the medical records of 65 patients diagnosed with lung cancer between 2015 and 2021 at a single medical oncology center in Al-Madinah city of Saudi Arabia. Results: The mean patients’ age was 59.2 years, with 50 (76.9%) males and 15 (23.1%) females; 37 (57%) smokers, and 28 (43%) non-smokers. The number of cases per year has increased gradually over six years from 2015 (n = 3) to 2020 (n = 13). The most prevalent histopathological diagnosis was non-small cell lung cancer (NSCLC) (n = 58, 89%) followed by small cell lung cancer (SCLC) (n = 5, 7.8%). NSCLC was frequently more common in smokers while squamous cell carcinoma was more frequent in non-smokers. Around 89% (n = 58) of the cases were diagnosed in late stage IV and the most common metastatic sites were to pleura and lymph nodes (n = 32, 49.2%). Program Death Legend-1 (PDL-1) was fairly expressed in 7/10 (70%) patients. Epidermal Growth Factor Receptor (EGFR) was mutated in 5/17 (29%) patients. Other mutations detected include Anaplastic Lymphoma Kinase (ALK) and phosphatidylinositol 3-kinase (PIK3C) mutations in two patients. Conclusions: Our study revealed that lung cancer is a significant burden in Al-Madinah city of Saudi Arabia. If the risk factors are not controlled, the number of cases may increase considerably. Health education about the risk factors and cancer prevention helps in early lung cancer detection.
