Among many types of cancers, smoking itself or following a diagnosis of cancer increase cancer specific mortality. Survival outcomes after early cancer diagnosis and treatment is the need to of the hour to be discussed.
Many studies were conducted especially The 2020 surgeon’s general report, but none of these earlier studies told us about relation of time between diagnosis and survival rate after quitting smoking. Survival outcomes after early cancer diagnosis and treatment
METHODS:
Cohort study was done to know the survival outcomes after cessation of smoking (when they were diagnosed with cancer) and receiving treatment within 6 months to5years.
A study was reported for according to Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline, which was approved by The University of Texas MD Anderson Cancer Center institutional review board. TRTP between January 1, 2006, and March 3, 2022.
More than 95% of data was provided via telemedicine. The primary investigation was self reported with abstinence at3 months, 6months,and 9 months along with the initial TRTP consultation. MD Anderson Cancer Center tumor registry recorded the primary outcome. Analyses were performed for the patients at the75th percentile as patients did not attain the median survival.
The study variables analyzed for this project according to according to the International Classification of Diseases for Oncology (ICD-O), third edition. Univariate Kaplan-Meier survival analyses were also performed among all patients and among the subgroups.
RESULTS :
The patients who were analyzed, 2254 (49.8%) were female, and the median (IQR) age was 55(47-62) years. The individuals who were died before the end of cessation treatment were excluded. The main analytical sample consisted of 4526 currently smoking patients who were diagnosed with cancer and also receiving cessation treatment. For those quitting smoking at 3 months, survival chances were increased over 15 years.
The patients who received tobacco treatment within 6 months of their cancer diagnosis, their survival outcomes were optimal. At the 75th percentile, their survival increased from 2.1 years among those who did not quit smoking vs 3.9 years patients who quit smoking.
Further less pronounced results were noted, when tobacco treatment began within 6 months to 5 years after the diagnosis. , with survival at 75th percentile of 4.8 years.
CONCLUSION
This cohort study results suggested that smoking cessation treatment which was evidence-based, started within 6 months of cancer diagnosis, maximizes the survival chances of the individual. This study supports the stopping of smoking as the earliest intervention for patients when they are diagnosed with cancer.
