Abstract
BACKGROUND: The purpose of this systematic review was to determine the prognostic value of continued smoking after diagnosis on survival and recurrence rates in head and neck cancer.
METHODS: A systematic search was performed and predefined inclusion and exclusion criteria were used to screen and select the articles. The remaining articles were critically appraised.
RESULTS: Six articles were used for data extraction. The survival rate of patients who continued to smoke was 21% to 35% lower compared with patients who quit smoking. The recurrence rate for continued smoking was 23% and 30% higher. In 1 study, there was no difference between continuation and cessation of smoking, and 1 study showed a higher recurrence rate for patients who continued to smoke, which was not statistically significant.
CONCLUSION: There is consistent evidence that survival rates are lower and recurrence rates are higher for patients who continue to smoke after being diagnosed with head and neck cancer. © 2015 Wiley Periodicals, Inc. Head Neck, 2015.
