Purpose: To evaluate tumour response, acute and late toxicity in nasopharyngeal cancer (NPC) patients treated with intensity modulated radiotherapy (IMRT) with cisplatin chemotherapy. Materials and Methods: 33 NPC patients, received IMRT concurrently with four to six cycles of cisplatin (30 mg/m2/day) every six weeks between May 2016 and July 2018, were evaluated prospectively. The doses to the planning target volumes of primary tumor and involved lymph nodes, uninvolved regional nodal areas were 70 Gy and 50 Gy respectively. All patients were evaluated for tumour and node response using response evaluation criteria in solid tumour (RECIST) criteri, acute and late toxicities according to CTCAE version 3.0 (common terminology criteria for adverse events), RTOG/EORTC (Toxicity criteria of the Radiation Therapy Oncology Group/the European Organization for Research and Treatment of Cancer). Results: At three months after chemoradiation, 81.8% and 18.2% of patients achieved complete and partial response, respectively. Grade 3 acute toxicities were oral mucositis (6.1%), dermatitis (3%). Grade 3 late toxicities were xerostomia 2/33(6.1%). There was no grade 3 to grade 4 neck fibrosis and trismus, none of the patients developed mandibular bone necrosis. Conclusion:Cisplatin concurrently with IMRT provided excellent tumour response, manageable toxicities and good compliance.

Purpose To investigate the feasibility of intensity-modulated radiation therapy (IMRT) with or without chemotherapy, and to assess toxicities, failure patterns, and survivals in patients with nasopharyngeal carcinoma (NPC). Patients and Methods Radiation consisted of 70 Gy given to the planning target volumes of primary tumor plus any N+ disease and 59.4 Gy given to subclinical disease, delivered over 33 treatment days. Patients with stage T2b or greater or with N+ disease also received concurrent cisplatin (100 mg/m2) on days 1, 22, and 43 followed by adjuvant cisplatin (80 mg/m2) on day 1; fluorouracil (1,000 mg/m2/d) on days 1 through 4 administered every 4 weeks for three cycles. Tumor, clinical status, and acute/late toxicities were assessed. The primary objective was to test the transportability of IMRT to a multi-institutional setting. Results Between February 2003 and November 2005, 68 patients with stages I through IVB NPC (of which 93.8% were WHO types 2 and 3) were enrolled. Prescribed IMRT (target delineation) was given to 83.8%, whereas 64.9% received chemotherapy per protocol. The estimated 2-year local progression-free (PF), regional PF, locoregional PF, and distant metastasis–free rates were 92.6%, 90.8%, 89.3%, and 84.7%, respectively. The estimated 2-year PF and overall survivals were 72.7% and 80.2%, respectively. Acute grade 4 mucositis occurred in 4.4%, and the worst late grade 3 toxicities were as follows: esophagus, 4.7%; mucous membranes, 3.1%; and xerostomia, 3.1%. The rate of grade 2 xerostomia at 1 year from start of IMRT was 13.5%. Only two patients complained of grade 3 xerostomia, and none had grade 4 xerostomia. Conclusion It was feasible to transport IMRT with or without chemotherapy in the treatment of NPC to a multi-institutional setting with 90% LRPF rate reproducing excellent reports from single institutions. Minimal grade 3 and lack of grade 4 xerostomia were encouraging.

125 Background: Treatment for locally advanced esophageal carcinoma is radiation and chemotherapy, with or without surgery. Radiation has traditionally been delivered with 3D conformal radiation therapy (3D CRT). This study evaluates late toxicity in patients treated with IMRT as well as early outcomes and acute toxicity. Methods: This is a retrospective review of 32 patients with esophageal carcinoma treated with IMRT at Mayo Clinic Florida from 2008 -2012. Pathology includes squamous cell and adenocarcinomas. Tumor sites include middle and lower thoracic and GE junction. Clinical stages are TX-T3, N0-3, M0-1. All patients received at least one cycle of concurrent chemotherapy. IMRT dose was 50.4 Gy in 28 fractions prescribed to a target volume including the tumor and regional lymphatics. IMRT plans utilized coplaner beams in a 7-9 beam arrangement or volumetric modulated arc therapy. Results: Median follow-up is 8.9 months (range 2.4-23.0) for all patients and 13.1 months (range 2.8-23.0 months) in surviving patients. Median patient age is 69 (range 46-87). Trimodality treatment was completed in 20 patients (62.5%). Surgery was either an open or minimally invasive esophagogastrectomy. The incidence of grade 3 or greater late toxicity at 1 year was 48% in surgery patients and 26% in non-surgery patients. The most common grade 3 or higher toxicity was esophageal strictures in 25%. The incidence of any grade 3 or greater acute toxicity was 65% in the surgery patients and 75% in the non-surgery patients. Overall survival (OS) for all patients at 18 months is 57% (CI 37-86%) and progression-free survival (PFS) is 60% (36-99%). OS and PFS for trimodality therapy at 12 months is 83% (66-100%) and 81% (63-100%) respectively and for bimodality therapy is 34% (12-93%) and 70% (33-100%) respectively. Conclusions: Increased late toxicity occurs in surgery patients, and increased acute toxicity in non-surgery patients. Lower survival in non-surgery patients may be due to early progression, morbidities which preclude surgery or improved survival with surgery. Overall, IMRT is a feasible treatment modality, which may be equally efficacious to 3D CRT for the treatment of esophageal carcinoma.

e295 Background: We aimed to investigate the patterns of failure (locoregional and distant metastasis), associated factors, treatment outcomes in nasopharyngeal carcinoma (NPC) patients treated with intensity modulated radiation therapy (IMRT) combined with chemotherapy, results of reirradiation in recurrent cases and its toxicity. Methods: From April 2006 to December 2011, 68 NPC patients were treated with IMRT and chemotherapy at our hospital. Median radiation doses delivered to gross tumor volume (GTV) and positive neck nodes were 66–70 Gy/33-35fractions. For recurrent cases reirradiation was given by SRS 25 -30 Gy/5 fractions or IMRT 50-60 Gy/25-30 fractions according to volume of recurrence and surrounding critical structures. The clinical toxicities, patterns of failures, locoregional control (LRC), distant metastasis control (DMC), disease free survival (DFS) and overall survival (OS) were observed. Results: The median follow up time was 52.2 months (range: 11-87). EBV infection positive was 63.2%.There were 7 locoregional recurrences, 3 regional recurrences with distant metastases and 11 distant metastases. The median interval from the date of diagnosis to failure was 26.5 months (range, 16-50 months). 6/10 (60%) locoregional recurrences were treated with re-irradiation +/- concurrent chemotherapy. Acute grade 3 and 4 mucositis were observed in 2 patients (28.6%); however no significant late toxicities were seen after reirradiation. Nodal recurrences were salvaged by neck dissection. The 5-year LRC, DMC, DFS and OS rates of whole cohort were 81.1%, 74.3%, 60.1% and 73.4% respectively. Cox regression analyses revealed that neoadjuvant chemotherapy, age and Epstein-Barr virus (EBV) were independent predictors for DFS. Conclusions: Distant metastasis is the most common pattern of failure after IMRT with SIB technique with or without neoadjuvant and concurrent chemotherapy in Saudi patients with NPC. Early detection of local and locoregional recurrences is important as reirradiation with IMRT or SRT with or without chemotherapy is still feasible option with acceptable toxicity. However, efforts should be made for proper patient selection.

Background: Intensity-modulated radiotherapy with concurrent chemotherapy attempt to maintain efficiency while limiting toxicity in the treatment of neck squamous cell carcinomas. Side effects of the therapy are both challenge during treatment such as treatment delay, increasing financial and hospitalization rate and also cause early and late toxicities, affects to patient performances and treatment outcomes. We aimed to assess acute and late toxicity in patients with head and neck squamous cell carcinoma (HNSCC) managed with concurrent chemoradiation therapy using intensity modulated radiation therapy (IMRT) technique. Methods: A prospective descriptive study of 120 patients suffering from non-metastatic HNSCC received Intensity-modulated radiotherapy concurrently with four to six cycles of cisplatin (30mg/m2/day/ weekly) from May 2017 to 2018 at Hue Central Hospital (Vietnam). The dose to the primary tumour and cervical lymph nodes totally taken was 70 Gy. Toxicities were gradedbased on the European Organization for Research and Treatment of Cancer (EORTC) and the Radiation Therapy Oncology Group (RTOG). Results: Acute toxicities were mainly at grade 1 with oral mucositis, dermatitis and nausea/vomiting. For late toxicities, grade 3 xerostomia accountings for 5.8%. Neck fibrosis and trismus were not at grade 3 to grade 4, grade 1 mandibular bone necrosis (3.4%) was found in 3 patients. Conclusions: Concurrent chemoradiation therapy with IMRT demonstrated a well-tolerated regime with manageable toxicities.

Abstract Background Plasma EBV DNA concentrations at the time of diagnosis (pre-EBV) and post treatment (post-EBV) have significant value for predicting the clinical outcome of nasopharyngeal cancer (NPC) patients. However, the prognostic value of the EBV concentration during radiation therapy (mid-EBV) has not been vigorously studied. Patients and methods This was a post hoc analysis of 105 detectable pre-EBV NPC patients from a phase II/III study comparing sequential (SEQ) versus simultaneous integrated boost (SIB) intensity-modulated radiation therapy (IMRT). Plasma EBV DNA concentrations were measured by PCR before commencement of IMRT, at the 5th week of radiation therapy and 3 months after the completion of IMRT. The objective was to identify the prognostic value of mid-EBV to predict overall survival (OS), progression-free survival (PFS) and distant metastasis-free survival (DMFS). Results A median pre-EBV was 6880 copies/ml. Mid-EBV and post-EBV were detectable in 14.3% and 6.7% of the patients, respectively. The median follow-up time was 45.3 months. The 3-year OS, PFS and DMFS rates were 86.0% vs. 66.7% (p = 0.043), 81.5% vs. 52.5% (p = 0.006), 86.1% vs. 76.6% (p = 0.150), respectively, for those with undetectable mid-EBV vs. persistently detectable mid-EBV. However, in the multivariate analysis, only persistently detectable post-EBV was significantly associated with a worse OS (hazard ratio (HR) = 6.881, 95% confident interval (CI) 1.699-27.867, p = 0.007), PFS (HR = 5.117, 95% CI 1.562–16.768, p = 0.007) and DMFS (HR = 129.071, 95%CI 19.031–875.364, p < 0.001). Conclusions Detectable post-EBV was the most powerful adverse prognostic factor for OS, PFS and DMFS; however, detectable mid-EBV was associated with worse OS, PFS especially Local-PFS (LPFS) and may facilitate adaptive treatment during the radiation treatment period.
