Weekly cisplatin and radiotherapy for low risk, locoregionally advanced human papillomavirus-positive oropharyngeal squamous cell carcinoma

Abstract

Background There is interest in different treatment strategies, including deintensification in good prognosis human papillomavirus-positive (HPV(+)) oropharyngeal squamous cell carcinoma (SCC). We reviewed our experience with weekly cisplatin in low-risk, locoregionally advanced HPV(+) oropharyngeal SCC since late 2009. Methods Data from patients with low-risk HPV(+) oropharyngeal SCC treated with weekly cisplatin (40 mg/m2) and 70 Gy radiotherapy were collected. Low risk was defined as stage III to IV oropharyngeal SCC excluding T1-2N1, T4 or N3 disease, or N2b to N2c disease in patients with >10 pack-year smoking history. Results Of 31 patients, the median age was 56 years (range, 41-69 ye..
