Background:
This review aims to compare survival outcomes of surgical versus non-surgical treatment of advanced-stage OPSCC.
Methods:
CINAHL, Cochrane Library, PubMed, and Scopus were searched. Studies comparing the survival of patients with advanced OPSCC treated surgically (±adjuvant therapy) or non-surgically were included. Meta-analyses hazard ratio (HR) and proportions (%) were performed for the outcomes of 2-, 3-, and 5-year overall (OS), disease-free (DFS), disease-specific (DSS), and relapse-free (RFS) survival.
Results:
Forty-four studies reporting on (N = 35 681) patients were included, with a mean age of 58.9. For advanced-stage disease, primary treatment with surgery and chemoradiotherapy (CRT) demonstrated the best 5-year OS, at 67.1% (95% CI 55.6-77.6). Survival outcomes favored Surgery + CRT over other primary treatment modalities.
Conclusions:
Surgical treatment with adjuvant CRT may be associated with better OS outcomes compared with non-surgical treatment. Further research is needed to determine superior treatment modalities in OPSCC subgroups, such as HPV+ tumors.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
