Given the favorable prognosis associated with HPV-positive oropharyngeal cancer, cancer care professionals are actively discussing the feasibility of de-escalating treatment strategy for this cohort of patients. The purpose of the study was to improve the treatment outcomes in patients with locally advanced HPV- positive oropharyngeal squamous cell carcinoma by identifying the optimal induction chemotherapy (ICH) regimen, in particular, by using a two-drug ICH. Material and Methods. The study included 27 patients with locally advanced (T3-4N0-1, or T1-4N2-3) P16-positive oropharyngeal squamous cell carcinoma. All patients received 3 cycles of ICT according to the TP (docetaxel + cisplatin) regimen. To assess the effect and toxicity of two-drug ICH, a control group of patients, who received ICH according to the standard three-drug TPF (docetaxel, cisplatin and 5FU) regimen, was formed. Results. In the TP group, complete response (CR) was achieved in 3 (11 %) patients, partial response (PR) in 17 (63 %), stable disease (SD) in 7 (26 %) patients. In the control group: CR 4 (20 %) patients, PR - 13 (60 %), SD - 4 (20 %) patients. The median follow-up time in the TP group was 9 months (range: 2 to 22 months). The 1-year progression-free (PFS) and overall survival (OS) rates were 88.2 % and 100 %, respectively. In the TPF group, the PFS and OS rates were 84.4% and 100 %, respectively. Conclusion. The results revealed that TP ICH regimen was non-inferior to the standard TPF regimen in the rates of the objective response, 1-year OS and PFS.
