Objective
The aim of the study was to evaluate the survival of lung cancer patients in Alor Setar, Kedah from year 2004
to 2010.
Materials & Methods
A retrospective cohort study was conducted involving 103 lung cancer patients treated in Hospital Sultanah
Bahiyah, Alor Setar, Kedah from January 2004 until December 2010. Patients’ information was obtained
from their medical records and telephone calls. Kaplan Meier product-limit (PL) estimates was applied and
expressed as percentages with 95% confidence intervals. The comparison of survival distributions in variable
groups were evaluated using the Log-rank test.
Results
The overall cumulative survival for lung cancer in Kedah was 83.5 (95% confidence interval (CI): 81.5, 85.5),
73.8 (95% CI: 65.4, 82.2), 62.1 (95% CI: 52.6, 71.5) and 33.0 (95% CI: 32.9, 51.2) percent for 1 month, 3 months,
6 months and 1 year respectively. There were significant higher one year survival probabilities of those
receiving first line (Yes, 38% vs No, 15%), receiving second line (Yes, 65% vs No, 28%), greater frequency of
chemotherapy cycle (6 cycle, 48 % vs stop chemotherapy, 10%), better score before chemotherapy (1, 45%
vs 3, 8%), lower than stage 4 (non stage 4, 56 % vs Stage 4, 20%), complete 3 months remission (complete
remission, 35% vs stop chemotherapy, 18%) and complete 6 months remission (complete remission, 58% vs
no chemotherapy, 15 %).
Conclusion
The survival of lung cancer patients treated in Alor Setar was comparable with other developed countries.
