Costs of Definitive Chemoradiation, Surgery, and Adjuvant Radiation Versus De-Escalated Adjuvant Radiation per MC1273 in HPV+ Cancer of the Oropharynx.
De-escalated treatment for human papillomavirus (HPV)+ oropharynx squamous cell carcinoma (OPSCC) has shown promising initial results. Health-care policy is increasingly focusing on high-value care. This analysis compares the cost of care for HPV+ OPSCC treated with definitive chemoradiation (CRT), surgery and adjuvant radiation (RT), and surgery and de-escalated CRT on MC1273.
MC1273 is a prospective, phase 2 study evaluating adjuvant CRT to 30 to 36 Gy plus docetaxel for HPV+ OPSCC after surgery for high-risk patients. Matched standard-of-care control groups were retrospectively identified for patients treated with definitive CRT or adjuvant RT. Standardized costs were evaluated before radiation, during treatment (during RT), and at short-term (6 month) and long-term (7-24 month) follow-up periods.
A total of 56 definitive CRT, 101 adjuvant RT, and 66 MC1273 patients were included. The CRT arm had more T3-4 disease (63% vs 17-21%) and higher N2c-N3 disease (52% vs 20-24%) vs both other groups. The total treatment costs in the CRT, adjuvant RT, and MC1273 groups were $47,763 (standard deviation [SD], $19,060], $57,845 (SD, $17,480), and $46,007 (SD, $9019), respectively, and the chemotherapy and/or RT costs were $39,936 (SD, $18,480), $26,603 (SD, $12,542), and $17,864 (SD, $3288), respectively. The per-patient, per-month, average short-term follow-up costs were $3860 (SD, $10,525), $1072 (SD, $996), and $972 (SD, $833), respectively, and the long-term costs were $978 (SD, $2294), $485 (SD, $1156), and $653 (SD, $1107), respectively. After adjustment for age, T-stage, and N-stage, treatment costs remained lower for CRT and MC1273 versus adjuvant RT ($45,450 and $47,114 vs $58,590, respectively; P < .001), whereas the total per-patient, per-month follow-up costs were lower in the MC1273 study group and adjuvant RT versus CRT ($853 and $866 vs $2030, respectively; P = .03).
MC1273 resulted in 10% and 20% reductions in global costs compared with standard-of-care adjuvant RT and definitive CRT treatments. Substantial cost savings may be an added benefit to the already noted low toxicity and maintained quality of life of treatment per MC1273.

Mature results of a prospective study of deintensified chemoradiotherapy for low-risk human papillomavirus-associated oropharyngeal squamous cell carcinoma.
The purpose of the current study was to determine quality of life and tumor control from a prospective phase 2 clinical trial evaluating deintensified chemoradiotherapy for favorable risk, human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma.
Patients with T0-T3, N0-N2c, M0, p16-positive disease and a minimal smoking history were treated with 60 grays of intensity-modulated radiotherapy with concurrent weekly intravenous cisplatin (30 mg/m2 ). The primary study endpoint was the pathologic complete response rate based on biopsy of the primary site and dissection of pretreatment positive lymph node regions. The pathologic complete response rate as previously reported was 86%. Herein, the authors report secondary endpoint measures of local control, regional control, cause-specific survival, distant metastasis-free survival, and overall survival, and patient-reported outcomes (European Organization for Research and Treatment of Cancer [EORTC] Quality of Life Questionnaire [EORTC QLQ-C30] and the Patient-Reported Outcomes version of Common Terminology Criteria for Adverse Events [PRO-CTCAE]).
A total of 44 patients enrolled with a median follow-up of 36 months (88% with ≥2 years). The 3-year local control, regional control, cause-specific survival, distant metastasis-free survival, and overall survival rates were 100%, 100%, 100%, 100%, and 95%, respectively. The mean before and 3-year after EORTC QOL scores were: global: 80 of 78; swallowing: 11 of 11; dry mouth: 16 of 41; and sticky saliva: 6 of 29. The mean before and 3-year after PRO-CTCAE scores were: swallowing: 0.4 of 0.7; and dry mouth: 0.4 of 1.4. Approximately 39% of patients required a feeding tube (median duration, 15 weeks; none were permanent). There were no ≥grade 3 late adverse events reported.
For patients with favorable-risk human papillomavirus-associated oropharyngeal squamous cell carcinoma, a substantially decreased intensity of therapy with 60 grays of intensity-modulated radiotherapy and weekly low-dose cisplatin produced better preservation of quality of life compared with standard therapies while maintaining excellent 3-year tumor control and survival.
