Title: A Prospective Phase 2 Trial of Reirradiation With Stereotactic Body Radiation Therapy Plus Cetuximab in Patients With Previously Irradiated Recurrent Squamous Cell Carcinoma of the Head and Neck

Abstract

Purpose: Salvage options for unresectable locally recurrent, previously irradiated squamous cell carcinoma of the head and neck (rSCCHN) are limited. Although the addition of reirradiation may improve outcomes compared to chemotherapy alone, significant toxicities limit salvage reirradiation strategies, leading to suboptimal outcomes. We therefore designed a phase 2 protocol to evaluate the efficacy of stereotactic body radiation therapy (SBRT) plus cetuximab for rSCCHN. Methods and Materials: From July 2007 to March 2013, 50 patients >18 years of age with inoperable locoregionally confined rSCCHN within a previously irradiated field receiving ≥60 Gy, with a Zubrod performance status of 0 to 2, and normal hepatic and renal function were enrolled. Patients received concurrent cetuximab (400 mg/m{sup 2} on day −7 and then 250 mg/m{sup 2} on days 0 and +8) plus SBRT (40-44 Gy in 5 fractions on alternating days over 1-2 weeks). Primary endpoints were 1-year locoregional progression-free survival and National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0 graded toxicity. Results: Median follow-up for surviving patients was 18 months (range: 10-70). The 1-year local PFS rate was 60% (95% confidence interval [CI]: 44%-75%), locoregional PFS was 37% (95% CI: 23%-53%), distant PFS was 71% (95% CI: 54%-85%), and PFS was 33% (95% CI: 20%-49%). Themore » median overall survival was 10 months (95% CI: 7-16), with a 1-year overall survival of 40% (95% CI: 26%-54%). At last follow-up, 69% died of disease, 4% died with disease, 15% died without progression, 10% were alive without progression, and 2% were alive with progression. Acute and late grade 3 toxicity was observed in 6% of patients respectively. Conclusions: SBRT with concurrent cetuximab appears to be a safe salvage treatment for rSCCHN of short overall treatment time.« less

  • Purpose: Despite treatment, prognosis of unresectable squamous cell carcinoma of the head and neck (SCCHC) is dismal. Cetuximab therapy has proven to increase the clinical activity of radiation therapy and chemotherapy in patients with locoregional advanced disease with an acceptable toxicity profile. We designed a phase 2 trial to evaluate the efficacy of docetaxel, cisplatin, and 5-fluorouracil (TPF) plus cetuximab (C-TPF) as an induction regimen in patients with unresectable SCCHN. Methods and Materials: A single-arm phase 2 trial was conducted. Eligible patients included those with untreated unresectable SCCHC, World Health Organization performance status of 0 to 1, 18 to 70 yearsmore » of age. Treatment consisted of four 21-day cycles of TPF (docetaxel, 75 mg/m{sup 2} day 1; cisplatin, 75 mg/m{sup 2} day 1; 5-fluorouracil [5-FU], 750 mg/m{sup 2} day 1-5) and cetuximab, 250 mg/m{sup 2} weekly (loading dose of 400 mg/m{sup 2}). Prophylactic granulocyte colony-stimulating factor and antibiotic support were given. After induction, sequential accelerated radiation therapy with concomitant boost (69.9 Gy) and weekly cetuximab therapy were delivered in the absence of disease progression. The primary endpoint was objective response rate (ORR) to C-TPF. Results: Fifty patients were enrolled across 8 centers. Median age was 54 years; disease was stage IV; oropharynx and hypopharynx were the most common primary sites. Eighty-two percent received 4 cycles of C-TPF, and 86% started sequential treatment based on radiation therapy and cetuximab. ORR after C-TPF was 86% (95% confidence interval [CI]: 73%-94%) and 24% had complete response (CR). With a median follow-up of 40.7 months, median overall survival (OS) was 40.7 months. The 2-year actuarial locoregional control (LRC) rate was 57%. The most common drug-related grade 3 or 4 toxicities during induction were neutropenia (24%), neutropenic fever (24%), and diarrhea (20%). There were 3 treatment-related deaths (6%). Conclusions: C-TPF yields high ORR and CR as induction treatment in unresectable SCCHN. However, hematologic toxicity is too high to recommend this regimen at the current dose.« less
  • Purpose: To evaluate the safety and efficacy of stereotactic body radiotherapy (SBRT) in previously irradiated patients with squamous cell carcinoma of the head and neck (SCCHN). Patients and Methods: In this Phase I dose-escalation clinical trial, 25 patients were treated in five dose tiers up to 44 Gy, administered in 5 fractions over a 2-week course. Response was assessed according to the Response Evaluation Criteria in Solid Tumors and [{sup 18}F]-fluorodeoxyglucose standardized uptake value change on positron emission tomography-computed tomography (PET-CT). Results: No Grade 3/4 or dose-limiting toxicities occurred. Four patients had Grade 1/2 acute toxicities. Four objective responses weremore » observed, for a response rate of 17% (95% confidence interval 2%-33%). The maximum duration of response was 4 months. Twelve patients had stable disease. Median time to disease progression was 4 months, and median overall survival was 6 months. Self-reported quality of life was not significantly affected by treatment. Fluorodeoxyglucose PET was a more sensitive early-measure response to treatment than CT volume changes. Conclusion: Reirradiation up to 44 Gy using SBRT is well tolerated in the acute setting and warrants further evaluation in combination with conventional and targeted therapies.« less
  • Purpose: To examine the effects the proteasome inhibitor bortezomib (VELCADE) on transcription factor nuclear factor-{kappa}B (NF-{kappa}B) and target genes and the feasibility of combination therapy with reirradiation in patients with recurrent head-and-neck squamous cell carcinoma (HNSCC). Methods and Materials: The tolerability and response to bortezomib 0.6 mg/m{sup 2} and 0.9 mg/m{sup 2} given twice weekly concurrent with daily reirradiation to 50-70 Gy was explored. Blood proteasome inhibition and NF-{kappa}B-modulated cytokines and factors were measured. Proteasome inhibition, nuclear localization of NF-{kappa}B phospho-p65, apoptosis, and expression of NF-{kappa}B-modulated mRNAs were compared in serial biopsies from accessible tumors. Results: The maximally tolerated dosemore » was exceeded, and study was limited to 7 and 2 patients, respectively, given bortezomib 0.6 mg/m{sup 2} and 0.9 mg/m{sup 2}/dose with reirradiation. Grade 3 hypotension and hyponatremia were dose limiting. Mucositis was Grade 3 or less and was delayed. The mean blood proteasome inhibition at 1, 24, and 48 h after 0.6 mg/m{sup 2} was 32%, 16%, and 7% and after 0.9 mg/m{sup 2} was 56%, 26%, and 14%, respectively. Differences in proteasome and NF-{kappa}B activity, apoptosis, and expression of NF-{kappa}B-modulated cell cycle, apoptosis, and angiogenesis factor mRNAs were detected in 2 patients with minor tumor reductions and in serum NF-{kappa}B-modulated cytokines in 1 patient with a major tumor reduction. Conclusions: In combination with reirradiation, the maximally tolerated dose of bortezomib was exceeded at a dose of 0.6 mg/m{sup 2} and the threshold of proteasome inhibition. Although this regimen with reirradiation is not feasible, bortezomib induced detectable differences in NF-{kappa}B localization, apoptosis, and NF-{kappa}B-modulated genes and cytokines in tumor and serum in association with tumor reduction, indicating that other schedules of bortezomib combined with primary radiotherapy or reirradiation may merit future investigation.« less
  • Purpose: This paper reports long-term results of RTOG 9903, to determine whether the addition of erythropoietin (EPO) would improve the outcomes of radiation therapy (RT) in mildly to moderately anemic patients with head and neck squamous cell carcinoma (HNSCCa). Methods and Materials: The trial included HNSCCa patients treated with definitive RT. Patients with stage III or IV disease received concomitant chemoradiation therapy or accelerated fractionation. Pretreatment hemoglobin levels were required to be between 9.0 and 13.5 g/dL (12.5 g/dL for females). EPO, 40,000 U, was administered weekly starting 7 to 10 days before RT was initiated in the RT + EPO arm. Results: A total ofmore » 141 of 148 enrolled patients were evaluable. The baseline median hemoglobin level was 12.1 g/dL. In the RT + EPO arm, the mean hemoglobin level at 4 weeks increased by 1.66 g/dL, whereas it decreased by 0.24 g/dL in the RT arm. With a median follow-up of 7.95 years (range: 1.66-10.08 years) for surviving patients and 3.33 years for all patients (range: 0.03-10.08 years), the 5-year estimate of local-regional failure was 46.2% versus 39.4% (P=.42), local-regional progression-free survival was 31.5% versus 37.6% (P=.20), and overall survival was 36.9% versus 38.2% (P=.54) for the RT + EPO and RT arms, respectively. Late toxicity was not different between the 2 arms. Conclusions: This long-term analysis confirmed that despite the ability of EPO to raise hemoglobin levels in anemic patients with HNSCCa, it did not improve outcomes when added to RT. The possibility of a detrimental effect of EPO could not be ruled out.« less
  • Purpose: To report our experience with a prospective protocol of external beam reirradiation (Re-RT) combined with cetuximab for patients with inoperable, recurrent squamous cell carcinoma of the head and neck (SCCHN). Patients and Methods: Between August 2008 and June 2010, 18 patients with inoperable recurrence of SCCHN after adjuvant or definitive radiotherapy (RT) and simultaneous or sequential cisplatin-based chemotherapy for primary SCCHN were enrolled. Acute and late toxicity from the experimental regimen were recorded every week during RT and every 3 months thereafter. Efficacy was assessed with repeated imaging using response evaluation criteria in solid tumors and clinical examinations 8-12more » weeks after completion of the treatment and every 3 months thereafter. Results: Median follow-up time for all patients was 9.4 (range: 3.85-31.7) months and for patients alive 30.4 (range: 15.7-31.7) months. Acute toxicity was generally mild or moderate. Five patients developed a grade 3 acneiform rash related to cetuximab. Late toxicity occurred as grade 3 trismus in five and as grade 3 abacterial salivary gland inflammation in one patient, respectively. Overall response rate was 47%. Median overall and progression-free survival for all patients was 8.38 months and 7.33 months, respectively. The overall survival rate was 44% at 1 year, with a 1 year local control rate of 33%. Conclusion: Notwithstanding the limitations of our preliminary data Re-RT combined with cetuximab for recurrent and inoperable SCCHN is feasible and the integration of newer targeted agents seems to be less toxic compared to conventional chemotherapy with encouraging response rates at least for a subset of patients.« less
