INTRODUCTION: lung cancer is the most common cancer and the leading cause of cancer death worldwide. This study aimed to provide an overview of the epidemiology of primary lung cancer in Morocco. The distribution of histological subtypes by sex and smoking status was also assessed.
METHODS: this was a retrospective and descriptive study using medical records of patients with primary lung cancer, diagnosed at two university hospitals in Morocco between 2014 and 2017.
RESULTS: a total of 606 patients (average age = 58.5 ± 10.64 years, men = 521) were included. Four hundred and forty-three men had a history of smoking against sex women. Most patients (85.68%) had respiratory symptoms at diagnosis. Over half of patients (53.03%) had a performance status <2 and 38.94% had at least another pulmonary disease at presentation. Chronic obstructive pulmonary disease (COPD) and tuberculosis were present in 23.43% and 18% of patients, respectively. The majority (72.27%) of men practiced an occupation associated with a significant risk of lung cancer. Adenocarcinoma was the main histological type in our series with 60.40%. Most (79.55%) patients were diagnosed at stage IV. Only 7.83% of patients benefited from surgery. The distribution of histological subtypes by sex and smoking habits showed that adenocarcinoma was more frequent in women (p=0.011), and squamous cell carcinoma in men (p=0.014). No differences between smokers and non-smokers were noted.
CONCLUSION: our results showed a decrease in the age of diagnosis and a late stage of the disease. Adenocarcinoma was the most frequent histological type.
