RESUMEN
BACKGROUND/AIM: Despite the global rise in the incidence of human papillomavirus (HPV)-positive oropharyngeal carcinoma (OPC) in recent years, its prevalence and oncological outcomes in patients living in rural areas of Northern Japan has not been explored and should be investigated. PATIENTS AND METHODS: A total of 105 patients with oropharyngeal squamous cell carcinoma who underwent HPV screening and received first-line treatment were included in this study. The annual changes in the number of patients, survival rates, and clinical factors affecting prognosis were examined. RESULTS: The HPV-positive rate in patients with OPC was low, with the lowest rate of 10.0% in 2013 and the highest rate of 46.7% in 2020. The number of HPV-negative cases remained almost unchanged, whereas the overall number of cases increased with the increasing number of HPV-positive cases. Additionally, HPV-positive cases exhibited a fairly good prognosis. CONCLUSION: The number of OPC cases increased not only in urban areas, but also in rural areas. HPV-positive cases had better outcomes than HPV-negative cases.

BACKGROUND/AIM: Although the efficacy of docetaxel, cisplatin, and 5-Fluorouracil (TPF) as induction chemotherapy has been confirmed, the therapeutic outcome and prognostic factors of concurrent chemoradiotherapy (CCRT) should be investigated. PATIENTS AND METHODS: Laboratory data of patients who underwent CCRT for advanced squamous cell carcinoma (SCC) of the head and neck were investigated to clarify the grade of side effects. Survival rates and prognostic scores were also calculated. Multivariate analysis was performed to examine the prognostic factors of the patients. RESULTS: Although there were significantly more advanced cases in the TPF group (n=72) than those in the cisplatin group (n=50), there were no significant differences in patient survival rates. In the TPF group, the lymphocyte count, albumin level, and C-reactive protein level of the patients before treatment were significantly correlated with patient outcomes. CONCLUSION: CCRT using the TPF regimen had remarkable treatment effects in advanced head and neck cancer.
