Aim
Lung cancer is the fifth most common cancer and the most common cause of cancer death in Australia. The age-standardised incidence of lung cancer was higher in Central Queensland (CQ) than that in whole Australia (50 vs 43 per 100,000 population per year) in 2010-2014. Adult smoking rate was 17% in CQ in 2015-16 (38% higher than that of whole Queensland). This study aims to determine the demographics and tumour characteristics of metastatic lung cancer patients who were registered and treated in Cancer Care Service of Central Queensland Hospital and Health Service (CQHHS) between 01/08/2016 and 31/05/2019.
Methods
The study is a retrospective, descriptive study of the patients with metastatic non-small cell lung cancer (NSCLC) and extensive stage small cell lung cancer (SCLC) who were registered and treated in Cancer Care service of CQHHS between 01/08/2016 and 31/05/2019. The patients list was generated from the MOSAIQ electronic record system, and a chart review was performed to identify the demographics and tumour characteristics of metastatic lung cancer cases.
Results
A total of 107 (54 male, 53 female) patients were identified as diagnosed with metastatic lung cancer between 01/08/2015 and 31/05/2019. Only 4 indigenous patients were identified. The overall mean age at diagnosis was 65 (range 44-87). 48 patients (45%) were <65 years at diagnosis. The numbers of patients with metastatic NSCLC and extensive stage SCLC were 91 and 16 respectively. Only 7 patients were identified as non-smokers. 5 patients had EGFR mutated metastatic adenocarcinoma of lung, 2 of whom were never-smoker.
Conclusion
In Central Queensland, the age-standardised incidence and the age-standardised mortality of lung cancer are higher than the nation-wide rates. This study will provide a detailed description of the unique demographics and tumour characteristics of metastatic lung cancer in CQ region.
