Trends in head and neck cancer incidence in Ho Chi Minh City, Vietnam between 1996 and 2015

Introduction: This study provides an analysis of head and neck cancer (HNC) cases over a 20-year period in Ho Chi Minh City, Vietnam. It aims to shed light on HNC's characteristics and trends in this highly populated urban region.

Methods: The analysis encompasses 8974 HNC cases, emphasising incidence rates, gender distribution, and the prevalence of different subtypes, including oral cavity, nasopharyngeal, oropharyngeal, and laryngeal/pharyngeal cancers. Ho Chi Minh City was chosen due to its extensive cancer reporting systems and its role as a major urban healthcare centre attracting a wide range of patients.

Results: The study reveals an increasing incidence of HNC in Ho Chi Minh City, with a notable predominance of male patients (73 %). The breakdown of HNC cases shows oral cavity cancer at 34 %, nasopharyngeal at 33 %, oropharyngeal at 12 %, and laryngeal/pharyngeal at 21 %. Compared to global averages, Vietnamese patients are diagnosed at an earlier age, with a noticeable trend of decreasing mean age of diagnosis over the study period.

Conclusion: This comprehensive study provides valuable insights into the HNC landscape in Ho Chi Minh City, revealing a slightly lower overall incidence but an earlier age of diagnosis compared to global trends. These findings suggest the need for region-specific public health initiatives and further research to clarify the epidemiological features of HNC in Vietnam.
