Effectiveness of treatment of oropharyngeal carcinoma patients

Aim: To analyze the results of treatment of patients with oropharyngeal carcinoma.

Materials and Methods: 276 patients with oropharyngeal carcinoma were treated in 2008-2021. Neoadjuvant chemotherapy consisted of three to six cycles: paclitaxel 175 mg/m2 and carboplatin 350 mg/m2 (or cisplatin 100 mg/m2) on the first day. The interval between cycles was 21 days. After the cycles, all patients were prescribed a course of radiation therapy in a total focal dose (TFD) of 65 Gy. The outcome of treatment was assessed by the degree of tumor regression according to RECIST criteria one month after the end of combination treatment. Statistical processing was performed using STATISTICA 6.1 software (StatSoftInc).

Results: The three- and five-year survival rates of the examined patients with oropharyngeal carcinoma after treatment were 40.8% respectively (95% CI 33.7 - 47.9) and 27.0%, (95% CI 20.6 - 33, 4) with a median survival of 36 months with 95% CI (35.5 - 40.2). Processing was performed using STATISTICA 6.1 software (StatSoftInc).

Сonclusions: Analysis of treatment of patients with oropharyngeal carcinoma with predominance of squamous cell carcinoma (90.6%), localized primarily in the palatine tonsil (73.2%), with the most common stages T3N1M0 (30.1%) and T3N1M0 %), with regional metastases to the lymph nodes of the neck (89.9%), showed that the effectiveness of treatment of patients is quite high, because in most of the examined in the short term after combined treatment there was complete or partial regression of the tumor (91.7%), no progression of the oncological process was detected in any of them.
