Interventions on Costs and Survival Rates of Lung Cancer Patients

Abstract

Lung cancer is characterized by the uncontrolled growth of cells in lung tissue, particularly in the respiratory tract lining. The disease has a high and alarming mortality rate, requiring prompt and appropriate management. This study aims to examine the costs and one-year survival rates of lung cancer patients at Dharmais Cancer Hospital. Data analysis was conducted in four stages: retrospective observational study using secondary data from medical records, describing patient characteristics and factors affecting survival and treatment costs, analyzing survival curves by cancer stage and intervention, and testing differences in survival curves using the log-rank test. The results show that higher survival rates are often inversely proportional to shorter survival times, and vice versa. Stage 1 patients exhibited the most extended survival despite low survival rates for inpatients (48 months, 25%) and outpatients (53 months, 15%). Intervention types 4.00 (chemotherapy and radiotherapy) and 7.00 (chemotherapy, radiotherapy, and surgery) effectively extended survival, although associated survival rates remained low. The highest inpatient treatment costs were observed in stage 2 patients, while the highest annual outpatient costs were linked to surgical interventions, highlighting the difference between per-episode and cumulative annual expenditures.
