Head and Neck Cancer: It's Not Just About Smoking (Anymore)
Head and neck cancer incidence is rising, especially oropharyngeal cancer linked to HPV. While tobacco and alcohol remain major risk factors, other factors like diet, oral health, and socioeconomic status also play a role. Survival rates remain relatively static, and disparities exist based on socioeconomic status.
Possible Conflicts of Interest
David I. Conway is a member of the International Head and Neck Epidemiology (INHANCE) consortium, which conducted many of the studies cited. However, the funding sources for the review itself don't present any obvious conflicts.
Identified Weaknesses
Reliance on Observational Studies
The review relies heavily on observational studies, which are prone to biases like recall bias and confounding. This makes it difficult to establish causal relationships between risk factors and HNC.
Limited Geographic Representation
The review acknowledges the limited representation of certain regions, particularly Southeast Asia and Africa, despite these areas having a high burden of HNC. This limits the generalizability of the findings.
Inconsistent Definitions of HNC
The varying definitions of head and neck cancer across studies introduce heterogeneity and make it challenging to compare and synthesize findings accurately.
Confounding by Tobacco and Alcohol
The dominant effect of tobacco and alcohol can overshadow the impact of other risk factors, making it difficult to isolate their independent contributions.
Rating Explanation
This review provides a comprehensive overview of HNC epidemiology, including trends, risk factors, and survival. While it relies heavily on observational studies and lacks representation from some key regions, its breadth and depth make it a valuable resource. The identified limitations prevent a rating of 5.
