ABSTRACT
BACKGROUND:
Determining the optimal follow-up for patients can help maximize the use of health care resources. This is particularly true in a growing epidemic such as human papillomavirus-positive oropharyngeal squamous cell carcinoma (HPV+OPSCC). The objective of the current study was to evaluate time to disease recurrence or late toxicity in this cohort of patients to optimize patient management.METHODS:
An institutional database identified 232 patients with biopsy-proven, nonmetastatic HPV+OPSCC who were treated with radiotherapy. A retrospective review was conducted in patients who were followed every 3 months for the first year, every 4 months in year 2, and every 6 months in years 3 to 5. Late toxicity (grade ≥ 3; toxicity was scored based on National Cancer Institute Common Terminology Criteria for Adverse Events [version 4]), locoregional control, distant control, and overall survival were assessed.RESULTS:
The median follow-up was 33 months. Based on Radiation Therapy Oncology Group (RTOG) 0129 study risk groupings, patients were either considered to be at low (162 patients; 70%) or intermediate (70 patients; 30%) risk. Concurrent systemic therapy was used in 85% of patients (196 patients). The 3-year locoregional control, distant control, and overall survival rates were 94%, 91%, and 91%, respectively. Late toxicity occurred in 9% of patients (21 patients). Overall, 64% of toxicity and failure events occurred within the first 6 months of follow-up, with a < 2% event incidence noted at each subsequent follow-up. Only 4 patients experienced their first event after 2 years.CONCLUSIONS:
HPV+OPSCC has a low risk of disease recurrence and late toxicity after treatment; approximately two-thirds of events occur within the first 6 months of follow-up. These data suggest that it may be reasonable to reduce follow-up in patients with HPV+OPSCC to every 3 months for the first 6 months, every 6 months for the first 2 years, and annually thereafter.Palavras-chave
