6079 Background: To report the long-term outcome and toxicitie of locally advanced nasopharyngeal carcinoma (NPC) treated with nimotuzumab plus intensity- modulated radiotherapy (IMRT) with or without chemotherapy. Methods: From October 2009 to March 2014, 257 newly histology-proven, non-metastatic NPC patients were retrospectively enrolled. They are aged 10-76 years. The distribution of disease was stage III in 150 (58.4%), stage IV A in 88 (34.2%), and stage IV B in 19 (7.4%). All the patients received the treatment of nimotuzumab plus IMRT, and 239 cases were used for cisplatin-based chemotherapy. Acute and late radiation-related toxicities were graded according to the Acute and Late Radiation Morbidity Scoring Criteria of Radiation Therapy Oncology Group. The accumulated survival was calculated according to the Kaplan-Meier method. Log-rank test was used to compare the survival difference. Multivariate analysis was performed using Cox’s proportional hazard model. Results: All patients had completed the combined treatment. With a median follow-up of 48 months (range, 13–94 months), the estimated 3-year and 5-year overall survival rates were 92.6% and 86.2%, respectively. Univariate analysis showed that age, T stage, clinical stage and neoadjvant chemotherapy were related with OS. Multivariate analysis indicated that age and clinical stage were independent prognosticators. The median cycle for nimotuzumab addition was 12 weeks. The incidence of grade 3–4 acute mucositis and leukocytopenia were 10.9% and 9.3%, respectively, with no cases of skin rash and infusion reaction. Xerostomia was the most common late complication, and the degree of dry mouth in most survivors was mild-to-moderate at the last follow-up time. Conclusions: Nimotuzumab plus IMRT with or without chemotherapy showed promising outcomes in terms of loco-regional control and survival, without increasing the incidence of radiation-related toxicities for patients.

Abstract Background: We compared outcomes and toxicities between concurrent retrograde super-selective intra-arterial chemoradiotherapy (IACRT) and concurrent systemic chemoradiotherapy (SCRT) for gingival carcinoma (GC).　Methods: We included 84 consecutive patients who were treated for non-metastatic GC ≥ stage III, from 2006 to 2018, in this retrospective analysis (IACRT group: n=66; SCRT group: n=18).Results: The median follow-up time was 24 (range: 1–124) months. The median prescribed dose was 60 (6–70.2) Gy (IACRT: 60 Gy; SCRT: 69 Gy). There were significant differences between the two groups in terms of 3-year overall survival (OS; IACRT: 78.8%, 95% confidence interval [CI]: 66.0–87.6; SCRT: 50.4%, 95% CI: 27.6–73.0; P = 0.039), progression-free survival (PFS; IACRT: 75.6%, 95% CI: 62.7–85.2; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.028) and local control rates (LC; IACRT: 77.2%, 95% CI: 64.2–86.4; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.015). In univariate analysis, age ≥ 65 years, decreased performance status (PS) and SCRT were significantly associated with worse outcomes (P < 0.05). In multivariate analysis, age ≥ 65 years, clinical stage IV, and SCRT were significantly correlated with a poor OS rate (P < 0.05). Patients with poorer PS had a significantly worse PFS rate. Regarding acute toxicity, 22 IACRT patients had grade 4 lymphopenia, and osteoradionecrosis was the most common late toxicity in both groups.Conclusions: This is the first report to compare outcomes from IACRT and SCRT among patients with GC. ALL therapy related toxicities were manageable. IACRT is an effective and safe treatment for GC.

6063 Background: A prospective, randomized, and multicentric phase II study was performed to evaluate the short-term efficacy and safety of Endostar plus intensity-modulated radiotherapy (IMRT) versus concurrent chemoradiotherapy(CCRT) in locally advanced low-risk nasopharyngeal carcinoma(NPC). Methods: From September 2014 to August 2016, 120 patients with low-risk NPC at stages III-IVa from 9 centers were randomly divided into experimental group (Endostar plus radiotherapy (ERT); n = 60) and control group (CCRT; n = 60). ERT patients were given Endostar (7.5 mg/m2/day) by continuous intravenous infusion (CIV) from 5 days before radiotherapy for consecutive 10 days for 2 cycles with an interval of 14 days. Then, ERT patients received 2 cycles of 10 days of maintenance treatment with Endostar after radiotherapy. The CCRT patients were given cisplatin (100 mg/m2) on days 1, 22, and 43 for 3 cycles. Immediate and 3-month efficacy and adverse effects were evaluated between the two groups. ClinicalTrials registration number was NCT02237924. Results: All patients were eligible for toxicity and response analysis. Regarding immediate efficacy, the complete response(CR) rates were 45.0% for ERT arm and 33.3% for CCRT arm in nasopharynx (P = 0.190), and 43.3% for ERT arm and 36.7% for CCRT arm in regional nodes (P = 0.456). Three months after RT, the CR rates were 71.2% for ERT arm and 60.0% for CCRT arm in nasopharynx (P = 0.151), and 74.6% for ERT arm and 63.3% for CCRT arm in regional nodes (P = 0.172). The rate and severity of leukopenia, hemoglobin reduction and thrombocytopenia in ERT arm were significantly lower than CCRT arm (P < 0.01). The occurrence rates of Xerostomia, oral mucositis, nausea / vomiting, constipation and weight loss in ERT arm were significantly lower than those in CCRT arm (P < 0.01). Conclusions: The present study demonstrates that ERT has similar short-term efficacy on locally advanced low-risk NPC compared with CCRT, but the acute adverse effects of ERT are fewer, and the compliance and tolerability of patients are better. Clinical trial information: NCT02237924.

Abstract Background: To evaluate short-term safety and efficacy of helical tomotherapy (HT) versus intensity-modulated radiotherapy (IMRT) in patients with nasopharyngeal carcinoma (NPC).Methods: Retrospective analysis of locally advanced nasopharyngeal carcinoma treated with radiotherapy and concurrent platinum based neoadjuvant chemotherapy (cisplatin 80 mg/m2 every 3 weeks for 1 cycle) in our hospital from February 2017 to October 2019, including 70 patients in HT group and 70 in IMRT group. The target area of ​​the tumor was delineated by magnetic resonance (MRI) imaging. The prescription doses delivered to the gross tumor volume (pGTVnx) and positive lymph nodes (pGTVnd), the high risk planning target volume (PTV1), and the low risk planning target volume (PTV2), were 69.96 Gy, 66-70 Gy, 60 Gy and 50-54 Gy, in 33 fractions, respectively. Acute reactions were evaluated according to the RTOG/EORTC criteria, whereas the therapeutic efficacy was assessed according to RECTST version 1.1 criteria in a 3-months period.Results: The CI of PGTVnx, PGTVnd, PTV1 and PTV2, and HI of PGTVnx, PTV1 and PTV2 in HT group was significantly better than those in IMRT group. The OAR Dmax and Dmean in HT group were better than those in IMRT group with a significant difference (all p <0.05). Patients in the HT group were significantly better than those in the IMRT group in the protection of acute parotid gland injury and hearing damage (p <0.05), but not other acute adverse reaction. No significant difference was found on the short-term efficacy illustrated by ORR between HT group and IMRT group (x2 = 0.119; p = 0.730).Conclusions: Compared with IMRT, HT has better radiophysical-related dosimetric advantages in radiotherapy for locally advanced nasopharyngeal carcinoma. Despite similar on short-term effects, HT has lower incidence of adverse reactions than IMRT.

Abstract PurposeIntensity-modulated-radiotherapy (IMRT) is still a standard of care for radiotherapy in locally advanced head and neck cancer (LA-HNSCC). Simultaneous-integrated-boost (SIB) and moderately hypofractionation offer an opportunity of individual dose painting and reduction of overall treatment time. We present retrospective data on toxicity and local-regional-control of a patient cohort with LA-HNSCC treated with an IMRT-SIB-concept in comparison to normofractionated 3D-conformal radiotherapy (3D-RT) after a long-term follow-up.MethodsBetween 2012 and 2014, n=67 patients with HNSCC (stages III/IV without distant metastases) were treated with IMRT-SIB either definitive (single/total doses: 2.2/66Gy, 2.08/62.4Gy, 1.8/54Gy in 30 fractions) or in the postoperative setting (2.08/62.4Gy, 1.92/57.6Gy, 1.8/54Gy). These patients' clinical course was matched (for gender, primary, and treatment concept) as part of a matched-pair-analysis with patients treated before mid-2012 with normofractionated 3D-CRT (definitive: 2Gy/50Gy followed by a sequential boost up to 70Gy; postoperative: 2Gy/60-64Gy). Chemotherapy/immunotherapy was given concomitantly in both groups in the definitive situation (postoperative dependent on risk factors). Primary endpoints were acute and late toxicity; secondary endpoint was loco-regional-control (LRC).Results67 patients treated with IMRT-SIB (n = 20 definitive, n = 47 adjuvant) were matched with 67 patients treated with 3D-RT. There were minor imbalances between the groups concerning non-matching-variables like extracapsular extension (ECE) and chemotherapy in IMRT-SIB.Significantly less toxicity was found in favor of IMRT-SIB concerning dysphagia, radiation dermatitis, xerostomia, fibrosis, and lymphoedema. After a median follow-up of 63 months, median LRC was not reached (IMRT-SIB) vs. 69.5m (3D-RT) (p=0.63).ConclusionThis moderately hypofractionated IMRT-SIB-concept showed to be feasible with less toxicity compared to conventional 3D-RT in this long-term follow-up observation.
