6078 Background: Chemoradiotherapy used for the treatment of locally advanced head and neck cancer (HNC) causes a high incidence of mucositis that may be accentuated by a reactivation of herpes simplex virus (HSV). To date, no study has evaluated the impact of antivirals used as prophylaxis to prevent mucositis or their severity. Methods: This is a retrospective observational study including patients who received at least one cycle of concurrent chemoradiotherapy for the treatment of head and neck cancer between January 2014 and June 2017 at the Centre hospitalier de l’Université de Montréal (CHUM). HSV negative patients were excluded. After approval by the IRB, we compared the incidence and severity of mucositis in HSV positive patients who started an antiviral prophylaxis before cycle 1 or 2 (prophylaxis group) to HSV+/unknown HSV patients who did not receive antiviral prophylaxis (control group). Emergency visits and hospitalizations related to mucositis were collected. Mucositis were assessed regularly by radiation oncologists during the treatment. Results: Of 482 patients who received concurrent chemoradiotherapy for HNC, 75 were HSV negative and 407 were included in this study. In the group with (n = 94) and without prophylaxis (n = 313), patients received carboplatin and 5-FU (77% vs 62%) and cisplatin (23% vs 38%) with concurrent radiation respectively. The rate of all grade mucositis in patients with and without prophylaxis (99% vs 96%; p = 0.19) was not statistically significant. The rate of grade 3 and 4 mucositis (42% vs 49%; p = 0.29), the rate of emergency visit (29% vs 28%; p = 0.91) and hospitalization (9% vs 8%; p = 0.80) were not statistically significant between each group. However, in a subgroup of patient receiving carboplatin and 5-FU, antiviral prophylaxis seems to decrease significantly the rate of grade 3 (49% vs 63%; p = 0.04). Conclusions: The addition of antiviral prophylaxis in HSV positive in patients undergoing concurrent chemoradiotherapy for locally advanced HNC didn’t decrease the rate of all grade mucositis. In the subgroup of patients receiving carboplatin and 5-FU mainly of oropharynx origin, HSV prophylaxis decreased the severity of mucositis.

PurposeTo establish the safety and toxicity profile of daily gefitinib with radiation alone or with concurrent chemoradiotherapy in previously untreated patients with locally advanced squamous cell head and neck cancer (LAHNC).Patients and MethodsPatients with intermediate-stage LAHNC were treated with concomitant boost radiation (RT) alone with escalating doses of daily gefitinib (250 or 500 mg; cohort I). Once a safety profile was determined with RT alone, patients with high-risk disease were then treated with daily gefitinib (250 or 500 mg), weekly cisplatin (CDDP; 30 mg/m2), and once-daily RT (cohort II). Patients also received post-RT gefitinib at 250 mg daily for a period of up to 2 years.ResultsTwenty-three patients were enrolled and assessable for toxicity. No dose-limiting toxicities (DLTs) were observed in patients treated in cohort I at either 250 or 500 mg of gefitinib daily with concomitant boost RT to 72 Gy. In patients receiving chemoradiotherapy and gefitinib (cohort II), DLTs included one grade 4 diarrhea and one grade 4 neutropenic fever. Fifteen patients started maintenance gefitinib, and eight (53%) experienced grade 1 to 2 acne-like skin rash and diarrhea, but no grade 3 or 4 toxicity occurred.ConclusionGefitinib (250 or 500 mg daily) was well tolerated with concomitant boost RT or concurrent chemoradiotherapy with weekly CDDP. Protracted administration of gefitinib for up to 2 years at 250 mg daily was also tolerated well.

Introduction: Radiation therapy has long played an integral role in the manage¬ment of locally advanced head and neck cancer (HNC), both for organ preservation and to improve tumor control in the postoperative setting. The aim of this research is to investigate the effects of adaptive radiotherapy on dosimetric, clinical, and toxicity outcomes for patients with head and neck cancer undergoing radiation therapy treatment. Many sources have reported volume reductions in the primary target, nodal volumes, and parotid glands over treatment, which may result in unintended dosimetric changes affecting the side effect profile and even efficacy of the treatment. Adaptive radiotherapy (ART) is an interesting treatment paradigm that has been developed to directly adjust to these changes.Material and methods: This research contains the results of 15 studies, including clinical trials, randomized prospective and retrospective studies. The researches analyze the impact of radiation therapy on changes in tumor volume and the relationship with planned radiation dose delivery, as well as the possibility of using adaptive radiotherapy in response to identified changes. Also, medical articles and abstracts that are closely related to the title of adaptive radiotherapy were researched.Results: The application of ART significantly improved the quality of life of patients with head and neck cancer, as well as two-year locoregional control of the disease. The average time to apply ART is the middle of the treatment course approximately 17 to 20 fractions of the treatment.Conclusion: Based on systematic review of the literature, evidence based changes in target volumes and dose reduction at OAR, adaptive radiotherapy is recommended treatment for most of the patients with head and neck cancer with the support of image-guided radiotherapy.

Background and Aims To evaluate the feasibility in clinical practice of alternating chemo-radiotherapy in locally advanced head and neck cancer patients. Patients and Methods From August 1993 to April 1998 at the Division of Medical Oncology of Parma, 48 consecutive patients were observed, and 38 (79%) started the Merlano chemo-radiotherapy. The characteristics of the patients were: males (32, 84%); median age, 57 years; PS <2 (32, 84%). The primary sites were the oropharynx (18, 47%), oral cavity (8, 21%), hypopharynx (7, 19%), larynx (5, 13%); stage IV disease was present in 29 (76%) patients. Twenty-five (66%) patients were married, and 24 (63%) resided outside of the city. Results The compliance was very low: 21 patients (55%) performed all the programmed cycles of chemotherapy, whereas only 5 patients (13%) performed the chemo-radiotherapy at full doses without any delay. The objective responses were 3 (8%) complete and 21 (55%) complete plus partial responses. Failures were 2 (5%) stable disease and 2 (5%) progressive disease, and the response was not assessable in 10 (26%). The median duration of the response was 8 months. The median overall survival and the time to progression were 18 and 13 months, respectively; the 5-year overall and relapse-free survival were 36% and 26%, respectively. Nine (24%) patients were still alive as of August 30, 2001, 8 (21%) of them without progression. Twenty-six patients (68%) died with a local-regional relapse. One patient (3%) died for a second cancer. Grade 3–4 hematologic toxicity was leukopenia (n = 25, 66%) and thrombocytopenia (n = 9, 24%); grade 3–4 non-hematologic toxicity was diarrhea (n = 3, 8%) and mucositis (n = 2, 5%). Two patients (5%) died for intestinal infarction and perforation possibly related to treatment. Conclusions Compliance to the chemo-radiotherapy was very poor. The response rate was lower than that reported in clinical trials, whereas overall survival was comparable. The alternating chemo-radiotherapy is a very complex treatment that cannot be easily applied in clinical practice; a careful selection of patients is mandatory not only considering oncologic and medical criteria, but also the level of awareness of the patient and his family.

16500 Background: Self identified racial groups share an unequal burden of head and neck cancer . Recent evidence suggests that outcome among races is different and the causes are multifactorial. Nonetheless, differences among ethnic groups have not been reported. Herein, we decided to analyze differences in treatment response and outcome among our white and Hispanic patient population treated for locally advanced head and neck cancer. Methods: Patients were identified using the tumor registry. We reviewed retrospectively the data from medical records. 100 white Hispanics (WH) and 50 white non-Hispanics (WNH) diagnosed with locally advanced head and neck cancer and treated at our institution from 2004 to 2005, were eligible for the study. Standard statistical analysis, including Kaplan-Meier survival curve and Cox proportional hazard models were used. P value of <0.05 was considered for statistical significance. Results: Preliminary results reveal that, in our study population, median age at diagnosis, gender, performance status (ECOG 0–2) and squamous cell histology did not differ significantly between the two groups. Stage 4 at diagnosis was more commonly observed in Hispanics as opposed to WNH (85.7% vs 68.6%) (P = 0.1). Surgery was more commonly used as an initial treatment option in Hispanics than WNH (42.8% vs 28.6%) (P = 0.18) while chemotherapy was less likely to be used (78.6% vs. 91.4%) (P = 0.15). Hispanics were more likely to smoke than WNH (P = 0.0003) and were equally exposed to chronic alcohol use. Patients from the Hispanic group were more likely to respond to therapy than whites by Chi-squared analysis but this difference was not statistically significant (P = 0.09). No differences were seen in disease free survival. Kaplan-Meier estimate of median overall survival was 16 months for Hispanics vs. 25 months for whites but this difference did not reach statistical significance (P = 0.26). Final analysis will be available at the time of the annual meeting. Conclusion: In our experience, a trend for decrease overall survival was noted in the Hispanic ethnic group. This may be in part due to more advanced stage at presentation. Nonetheless, in order to definitively answer this question, further research is warranted.

6064 Background: An oral fluoropyrimidine, S-1, has shown high efficacy against head and neck cancer (HNC) with a response rate of 34% and preclinical data has demonstrated a possible synergy with platinums and taxanes. The aim of this study was to determine the maximum tolerated dose (MTD) of a combination therapy with TPS in patients (pts) with locally advanced or recurrent/ metastatic HNC. Methods: The eligibility criteria were: histologically proven squamous cell carcinoma of the head and neck with recurrent/metastatic and locally advanced lesions, PS 0–1, age =75 years, adequate organ function, and no prior chemotherapy. Chemotherapy consisted of 1-hour infusion of docetaxel at escalating doses of 50 and 60 mg/m2, 2-hour infusions of cisplatin at 70 mg/m2/day on day 1 and S-1 twice daily on days 1–14 at escalating doses of 40, 60, and 80 mg/m2/day. The treatment was repeated every 4-weeks. Results: Twenty two pts were enrolled. These were 17 males and 5 females with a median age of 50 years (22–74). There were 11 locally advanced and 11 metastatic cases. Median of 3 cycles were administrated (range 1–6; total 77 cycles). Anorexia, nausea, neutropenia and anemia were the most frequently observed adverse events. Grade 3 or 4 hematological toxicities were neutropenia (59%), febrile neutropenia (0%), anemia (14%) and thrombocytopenia (0%). Although a total of 12 pts were treated with TPS at doses of 60/70/80 mg/m2/day, one-dose limiting toxicity (grade3 infection) was observed at these doses, but MTD was not reached. As the approved dose of S-1 is 80 mg/m2, further dose escalation was not conducted. In a total of 22 pts treated with the TPS, 3 (1 locally advanced, 2 metastatic cases) achieved complete response and 11 (7 locally advanced, 4 metastatic cases) achieved partial response according to RECIST with an overall response rate of 64%. Conclusions: The TPS combination was well tolerated in pts with locally advanced or recurrent/ metastatic HNC. Although MTD was not reached and the data were preliminary, the antitumor activity was very promising, and this warrants further investigation. No significant financial relationships to disclose.

6021 Background: An oral fluoropyrimidine, S-1, has shown high efficacy against head and neck cancer (HNC), with a response rate of 34%. We investigated the maximum tolerated dose (MTD) of combination therapy with docetaxel, cisplatin and S-1 (TPS) in patients (pts) with locally advanced or recurrent/metastatic HNC. Methods: Eligibility criteria were histologically proven HNC, PS 0–1, age ≤75 years, adequate organ function, and no prior chemotherapy. Treatment consisted of 1-hour infusion of docetaxel at escalating doses of 50, 60 and 70 mg/m2, 2-hour infusion of cisplatin at 70 mg/m2/day on day 1, and S-1 twice daily on days 1–14 at escalating doses of 40, 60, and 80 mg/m2/day. This regimen was repeated every 3 or 4 weeks. Pts with locally advanced HNC received concurrent chemoradiotherapy after completion of 3 cycles of TPS. Results: Forty pts were enrolled, consisting of 33 males and 7 females with a median age of 50 years (range 22–74 years). Twenty-nine cases were locally advanced cancer and 11 were metastatic cancer. 116 cycles (median = 3, range 1–6) were administered in 6 dose levels. Grade 3 or 4 hematological toxicities were neutropenia (59%), febrile neutropenia (13%), and anemia (8%), whereas no grade 3 or 4 thrombocytopenia was seen. Two dose-limiting toxicities (DLTs) were observed at dose level 5 (TPS: 70/70/80 mg/m2/day every 3 weeks), namely one grade 3 infection and one grade 3 hyperbilirubinemia, establishing this as the MTD. Of 12 pts treated at dose level 6 (TPS: 70/70/60 mg/m2/day every 3 weeks), three DLTs were seen, namely one grade 3 diarrhea, one grade 3 ALT/AST and one grade 2 creatinine elevation. Of a total of 40 pts, 6 achieved a complete response and 22 a partial response according to RECIST, giving an overall response rate of 70%. Conclusions: The TPS combination was well tolerated. The recommended phase II dose was determined to be TPS at 70/70/60 mg/m2/day every 3 weeks. Antitumor activity was highly promising, and warrants further investigation.
