Lung cancer is the commonest cancer with highest mortality worldwide. However, survival data is lacking in Malaysia. This study intended to determine the survival of our lung cancer patients and factors affecting its survival. All lung cancer patients confirmed by histology from 1st January 2014 to 31 December 2017 in Hospital Tengku Ampuan Afzan, Kuantan were recruited and their demographic data, ECOG performance status, staging and treatment were recorded. Survival time was defined in week from the date of histological diagnosis to the date of death. Kaplan-Meier curve was used to determine median overall survival and log-rank test was used to test the survival differences between each subgroup. Multivariate analysis using COX regression was used to determine factors affecting its survival. A total 170 patients were included for survival analysis. Median age was 63years old and majority were males (74%) and smokers (64%). Adenocarcinoma (74.7%) was the most common histology followed by squamous cell carcinoma (18.8%). Almost all patient present at stage 3 or 4 (98%) but majority had ECOG 0-2 (64.3%). Median overall survival was 28.7weeks. In the multivariate analysis, “supportive treatment” and “poor ECOG performance status” were independent predictors of death with the hazard ratio of 1.4 (95%CI 1.17 to 1.66) and 3.0 (95%CI 2.05 to 4.39) times respectively. In conclusion majority of lung cancer patients in Pahang presented with advanced disease with overall median survival of 28.7 weeks. Patients treated with supportive care and poor ECOG performance status were two independent poor prognostic factors for survival.
