Background and Lung cancer is a public health problem worldwide. Identifying the epidemiological characteristics of involved patients can play an important role in designing analytical studies. The aim of this study was to identify the epidemiology of patients with lung cancer attending Tooba clinic and Imam Khomeini Hospital in Sari, Iran.
In this descriptive study, a sample size of 229 patients with lung cancer were chosen using census sampling. SPSS V22 was used for data analysis applying descriptive and analytic tests.
Of 229 patients, 74.2% were males. The mean ages of male and female patients were 63.4±12.6 and 64.6±12.01, respectively, indicating no significant difference between the two groups (P=0.534). The majority of samples (78.6%) had non-small-cell-lung cancer and the method of diagnosis was biopsy in 88.9%. The most and least common sites of involvement were the upper edge of the right lung (22.3%) and the upper lobe of the left lung (18.8%), respectively. Among the patients, 85.1% were in stage IV and chemotherapy was the main treatment in most of the patients (57%).
This study showed that men were more infected with lung cancer. We found that the average age of female patients was slightly more than that of male patients. Most of the patients were diagnosed with non-small cell lung carcinoma. The majority of patients were diagnosed at higher stages that were made at advanced and metastatic stages.
