ObjectiveTumor volume and regression after external beam radiotherapy have been shown to be accurate parameters to assess treatment response via magnetic resonance imaging (MRI). The aim of the study was to evaluate the prognostic value of tumor size reduction rate after external beam radiotherapy and chemotherapy prior to brachytherapy.MethodsPatients with locally advanced cervical cancer treated at two French comprehensive cancer centers between 1998 and 2010 were included. Treatment was pelvic external beam radiotherapy with platinum based chemotherapy followed by brachytherapy. Records were reviewed for demographic, clinical, imaging, treatment, and follow-up data. Anonymized linked data were used to ascertain the association between pre-external and post-external beam radiotherapy MRI results, and survival data.Results185 patients were included in the study. Median age at diagnosis was 45 years (range 26–72). 77 patients (41.6%) were International Federation of Gynecology and Obstetrics stage IB2-IIA disease and 108 patients (58.4%) were stage IIB-IVA. Median tumor size after external beam radiotherapy and chemotherapy was 2.0 cm (range 0.0–8.0) and median tumor size reduction rate was 62.4% (range 0.0–100.0%). Tumor size and tumor reduction rate at 45 Gy external beam radiotherapy MRI were significantly associated with local recurrence free survival (P<0.001), disease free survival, and overall survival (P<0.05). Tumor reduction rate ≥60% was significantly associated with a decreased risk of relapse and death (HR (95% CI) 0.21 (0.09 to 0.50), P=0.001 for local recurrence free survival; 0.48 (0.30 to 0.77) P=0.002 for disease free survival; and 0.51 (0.29 to 0.88), P=0.014 for overall survival).ConclusionsTumor size reduction rate >60% between pre-therapeutic and post-therapeutic 45 Gy external beam radiotherapy with concurrent chemotherapy was associated with improved survival. Future studies may help to identify patients who may ultimately benefit from completion surgery, adjuvant chemotherapy, and closer follow-up.

Abstract Background Locoregional recurrence is common in patients with locally advanced differentiated thyroid carcinoma (DTC). Our aim was to find out the rate of locoregional control of the disease after external beam radiotherapy (EBRT) of the neck and mediastinum in patients with DTC and pT4 tumor. Patients and methods Altogether 91 patients (47 males, 44 females, median age 61 years) with DTC had EBRT of the neck and mediastinum as part of the multimodal treatment of pT4 tumor (63 cases pT4a, 28 cases pT4b) from the year 1973 to 2015. Data on clinical factors, histopathology and recurrence were collected. Disease-free, disease-specific and overall survival was calculated. Results Median tumor size was 5 cm (range 1–30 cm). Out of 91 patients, 23 had distant and 38 regional metastases. A total or near-total thyroidectomy, lobectomy, subtotal thyroidectomy and lymph node dissection was performed in 70%, 14%, 2% and 30% of cases, respectively. Thirteen percent of patients were not treated with surgery. All patients had EBRT and 39 had chemotherapy. Radioiodine (RAI) ablation of thyroid remnant and RAI therapy was applied in 90% and 40% of cases, respectively. Recurrence was diagnosed in 29/64 patients without a persistent disease: locoregional and distant in 16 and 13 cases, respectively. Five-year and ten-year disease-free survival rate was 64% and 48%, respectively. Conclusions The majority of patients with DTC and pT4 tumors who were treated with EBRT of the neck and mediastinum region as part of multimodal treatment have long-lasting locoregional control of the disease.

5535 Background: To evaluate the safety and efficacy outcomes of concurrent cetuximab plus IMRT and cisplatin in Chinese patients with LA NPC. Methods: Patients with primary stage III-IVb (UICC/AJCC 2002 staging system) and non-keratinizing NPC were enrolled in this prospective, multicentric, phase II study. Cisplatin (80mg/m2,q3week) and cetuximab (400mg/m2 one w before radiation, and then 250mg/m2/w) were given concurrently. The prescription dose of IMRT to GTVnx (primary tumor in nasopharynx) was 66 Gy - 75.9 Gy, GTVnd (positive cervical lymph nodes) was 60 Gy - 70Gy, The response rate was evaluated according to RECIST 1.0 criteria, and adverse events (AEs) were graded according to NCI CTCAE V3.0 criteria. Results: From July 2008 to April 2009, 100 patients were enrolled (74 male), with median age of 43 years. The proportion of stage III, IVa and IVb patients were 71%, 22% and 7% respectively. 99% of enrolled patients completed the planned treatment. AEs were within the expected range and manageable. No toxic death occurred during the treatment. Acneiform skin eruptions, mucositis, in-field dermatitis, xerostomia and neucopenia were the most common seen AEs, with 64% grade 2/3 acneiform eruptions, 26% grade 2/3 in-field dermatitis, 90% ≥ grade 2 mucositis (2 cases of grade 4 mucositis with spontaneous bleeding), 40% ≥ grade 2 xerostomia and 8% grade 2/3 neucopenia. With a median follow-up time of 23.5 months, the 2 year overall survival (OS), disease-free survival (DFS), local recurrence-free survival, regional (cervical lymph node) recurrence free survival and distant metastasis-free survival rates for the ITT population were 91%, 89%, 90%, 90% and 89%, respectively Multivariate analysis showed that N stage was the only prognostic factor for OS (p=0.0392, HR=2.946) and DFS (p=0.0062, HR=4.246) in these patients. Conclusions: Cetuximab combined with IMRT plus concurrent cisplatin in patients with LA NPC shows satisfactory 2-year locoregional control rate and 2-year overall survival. The combination seems to be well tolerated with a manageable side-effect profile.

Background/Purpose: Gastric gastrointestinal stromal tumors (GISTs) have a highly variable clinical course, and recurrent disease sometimes develops despite curative surgery. This study was undertaken to investigate the surgical role in treating gastric GISTs and evaluate the clinicopathological features of a large series of patients who underwent curative resection for gastric GISTs to clarify which features were independent prognostic factors. Methods: The clinicopathological data of 406 patients with gastric GISTs who underwent curative resection at 4 university hospitals in Daegu, South Korea, from March 1998 to March 2012 were reviewed. All cases were confirmed as gastric GISTs by immunohistochemical staining, in which CD117 or CD34 was positive. Clinical follow-up was performed periodically, and disease-free survival rates were retrospectively investigated using the medical records. Results: The mean follow-up period was 42.9 months (range: 2-166). There were 11 recurrent patients (2.7%). Due to the small number of recurrences, age, sex and location were controlled using propensity score matching before performing any statistical analysis. Tumor size, mitotic count, NIH classification, and cellularity were judged to be independent prognostic factors for recurrence by univariate analysis. In a multivariate analysis, tumor size and mitotic count were significantly and independently related to recurrence, and tumor size was determined to be the most important prognostic factor for recurrence after curative resection (hazard ratio: 1.204; p < 0.01). Conclusions: The results of this multicenter study demonstrate that disease-free survival rates are good. Tumor size was disclosed as the most important factor for recurrence in gastric GIST patients who underwent radical resection.

5574 Background: RT with concurrent chemotherapy is superior to RT alone as treatment for locally advanced SCCHN. Gem is a potent radiosensitizer in vitro and in vivo and in addition has a good activity in SCCHN. Exploitation of these properties was the rationale for a single institution phase II study which evaluates the efficacy and toxicities of standard RT + weekly low dose Gem. Methods: Eligible were patients with primary inoperable or locally advanced stage III and IV SCCHN. Treatment: Planned RT was 70 Gy over 7 weeks with weekly Gem 100 mg/m2 within 2 hours prior to RT (Eisbrüch et al., ASCO, 1997, 1998). Presented endpoints are response rate (according to WHO), acute and late toxicity (according to NCICTC), disease free survival (DFS), local relapse free survival (LRFS) and overall survival (OS). Results: 26 patients (21 male, 5 female; performance status 0–2; no prior treatment) entered the study between November 1998 and September 2003. Median age was 56 years (range 48–78). Tumor sites were oropharynx (6), hypopharynx (17), glottis (1), paranasal sinus (1), unknown (1). Clinical stage was III (2) or IV (24). 7 Patients had T4N2 disease and 2 had T4N3 disease. Patients received a median of 7 Gem cycles (range 2–8) and a median of 70 Gy (66–84.75). 7 patients underwent radical neck dissection. Grade 3–4 acute toxicities included mucositis (22/26), dermatitis (18/26), pharyngitis and/or oesophagitis (21/26), pain (7/25), xerostomia (1/24), neutropenia (1/26) and anemia (1/26). 21/26 patients needed tube feeding and 21/26 needed to be hospitalized. After recovery from acute toxicity 6/23 could feed normally, 5/23 needed soft food, 5/23 were able to swallow liquid food and 2/23 required permanent tube feeding. Response was evaluable in 22 patients (11 CR, 11 PR). Intial relapse was at distant sites in 9/26 and local in 8/26. Median follow up of the patients still alive is 46 months. Median OS is 576 days, median DFS is 401 days, median LRFS is not reached. 7/26 remain free of disease more than 3 years after end of treatment. Conclusions: RT + Gem (100 mg/m2/week) is feasible but toxic. The combination is highly active in SCCHN and provides a good long term local control. [Table: see text]

9069 Background: Pediatric nasopharyngeal carcinoma (PNC) represents a locally advanced undifferentiated tumor. In this study, clinical experience and therapeutic results of 24 children with newly diagnosed PNC, treated in a single oncology institution in India over a period of 5 years, are analyzed. Methods: 24 patients (23 males and 1 female) 7–14 years old (median = 12) from Jan 2000 to Sep 2005 with PNC were retrospectively evaluated. 18/24 patients were evaluable. 16 patients received induction chemotherapy followed by radiotherapy while 1 patient was offered concurrent chemoradiotherapy, 1 patient received radiotherapy alone. 15/16 patients received postradiation chemotherapy. The agents used in induction and adjuvant therapy were cisplatin (100 mg/m2) on day 1 and 5-fluorouracil 750 mg/m2 for 5 days. The dose of radiotherapy used was 60 gray in 30 fractions. Results: The time of onset of symptoms to diagnosis ranged from 1 month to 9 months with a median of 5.5 months. Histopathology was lymphoepithelioma in 5 patients (27.7%) while 13 patients (72.2%) had poorly differentiated carcinoma. Disease extent was T2 (n = 7), T3 (n = 6), and T4 (n = 5); N1 (n = 5), N2 (n = 7), and N3 (n = 5). 7 patients had intracranial invasion. None had metastatic disease on presentation. 13 patients (72.2%) achieved major response which included 7 (38.8%) complete remission and 6 (33.3%) partial remission after the induction chemotherapy and radiotherapy. 4 (22.2%) had progressive disease. Another 3 (16.6%) attained complete remission after post radiation chemotherapy which consisted of two cycles of cisplatin and 5-flourouracil. The follow up ranged from 5 months to 84 months with a median follow up of 35 months. The disease free survival ranged from 10 months to 53 months with a median of 33 months. The patients who had a better response to induction chemotherapy had a better disease free survival. Out of 7 patients who attained complete remission 2 relapsed with a median time to first relapse of 9.5 months. Toxicity to therapy was modest. Only one patient had grade 4 neutropenia and mucositis. There was no therapy related mortality. Conclusion: Chemoradiotherapy for nasopharyngeal carcinoma in children is an effective treatment modality with minimal toxicity. No significant financial relationships to disclose.

16541 Background: CRT protocols for locally advanced HNC commonly utilize single agent cisplatinum as the radiation- sensitizing chemotherpy. This is typically administered in q 3 weekly doses of 100 mg/sq m concomitantly with XRT. However, many pts are not candidates for this dose and schedule of cisplatinum delivery due to co-morbidities. Limited data are available regarding the efficacy of alternate dosing of platinum analogues.We therefore analysed our experience with alternate dosing of cisplatin or carboplatin administered concomitantly with XRT. Methods: IRB approval was obtained for this retrospective analysis. Tumor registry and pharmacy data were reviewed to identify eligible pts. between 2004–2006 who were treated with alternate dosing of platinum with XRT. Pt characteristics recorded included: age, gender, stage, site of disease, type of chemotherpeutic agent used carboplatin or cisplatinum, number of doses administered, local disease free survival and overall survival. Results: Eleven pts were identified. Median age: 64 years (44–75); Gender: M:F::8:3; Sites: Oral cavity: n=2; Pharynx: n=11; Stage III: n=3; Stage IVa &b: n=8. Cisplatin weekly (doses 30–40mg/sqm): n=8; Carboplatin weekly AUC=2: n=3; Cisplatin weekly, changed to carboplatin: n=1. Nine of 11 pts achieved a local CR (82%); one pt has achieved a near CR and one pt achieved a PR and required salvage laryngectomy. At a median follow up of 14 mos (range: 4–34), all pts remain alive. In addition to the pt that achieved a PR after initial treatment, one other pt has required surgical salvage at 23 mos post CRT. No treatment related mortality occurred in this series. Conclusions: Weekly administration of cisplatin and carboplatin appears to be a feasible alternative to standard dose and schedule of cisplatin with acceptable efficacy. Future studies should compare targetted therapies such as cetuximab with or in combination with weekly platinum regimens during CRT for pts not eligible for standard dose cisplatinum. No significant financial relationships to disclose.

e15541 Background: Definitive treatment with concurrent cisplatin and radiation is the standard of care for locally advanced cervical cancer. The optimal management of patients with a contraindication to cisplatin has not been established. We conducted a retrospective audit of the impact of concurrent chemoradiation in a cohort of patients (pts) with locally advanced cervical cancer. Methods: All pts with locally advanced cervical cancer treated with definitive radiation were entered into a prospective database. Information regarding their demographics, stage, histology, recurrence and survival were recorded. Pharmacy records were reviewed to determine concurrent chemotherapy use. The primary endpoint was overall survival, and secondary endpoints were disease free survival and rates of primary, nodal or distant failure. Univariate and multivariate analyses were performed, incorporating known prognostic factors of age, FIGO stage, uterine body involvement, tumour volume on MRI and nodal involvement. Results: 442 pts were treated from Jan 1996 to Feb 2011. Median age was 59 (range 22-94); 89% had squamous histology and 64% node-negative disease. 269 pts received cisplatin, 59 received carboplatin because of a contraindication to cisplatin and 114 received no concurrent chemotherapy (most prior to 1999). Overall survival adjusted for other prognostic factors was significantly improved with use of concurrent cisplatin compared to radiation alone (HR 0.53, p=0.001), as was disease free survival and the rate of distant failure. Use of concurrent carboplatin was not associated with any significant benefit compared to radiation alone in terms of overall survival or disease free survival on univariate or multivariate analyses. Conclusions: The results of this audit are consistent with the known significant survival benefit with concurrent cisplatin chemoradiation. However, there did not appear to be any significant benefit associated with concurrent carboplatin although there are potential confounding factors in this small cohort. The available evidence in the literature favors the use of non-platinum chemotherapy rather than carboplatin in pts with contraindications to cisplatin.

e17569 Background: Concurrent Cisplatin with radiotherapy improves outcomes in locally advanced squamous cell carcinomas of the head neck.Cisplatin at 35mg/m2(weekly) raise compliance & hospitalization. There are only few reports on efficacy and toxicity of low dose Cisplatin (6mg/m2). Hence the purpose of this study was to evaluate the compliance and clinical outcomes between two concurrent cisplatin chemotherapy regimens & to see long term effects. Methods: Total 50 patients were included in study from Nov 2015 to Mar 2017 with 25 in each group. Radiotherapy given 70Gy/35# in 7weeks & Cisplatin at 35mg/m2 weekly (Group I) and 6mg/m2 daily (Group II). Assessment of toxicity was done by RTOG scoring criteria. WHO Response criterion was used to assess clinical response. Median follow up was 6 months. Results: Group I(80%) and Group II(84%)patients completed Radiotherapy. In Group I 48% patients received less than 6 cycles and Group II 40% received ≤25 cycles chemotherapy. Median OTT in Group I & II in was 51 & 52days. Neutropenia & Mucositis statistically insignificant between both groups.There was no statistical difference in complete response between the two groups. In Group I 40% patients developed Progressive disease on follow up as compared to 12% in Group II(p-0.02). After 1.5 years of follow up, Group I vs Group II 4 patients had complete response, 6 had recurrence & 11 vs 4 patients expired (p-0.03). At a median follow up of 6 months overall survival in Group I and II was 56% and 44%(p-0.39). While as median disease free survival in Group I & II was 6.6 & 11.9 months(p-0.14). Conclusions: Low dose daily Cisplatin offers ease of administration in the outpatient clinic, better tolerability and better quality of life.Group II patients were more compliant in terms of patients receiving chemotherapy or completing radiotherapy. At median follow up of 6 months there was no statistical difference in terms of overall and disease-free survival. The statistical difference was seen in terms of patients expired in Group I (44%) as compared to Group II (16%). Therefore, we need a larger number of patients for the use of low dose Cisplatin to be evaluated in future clinical trials.

Background: Standard treatment for locally advanced cervical cancer is external beam radiotherapy followed by brachytherapy (BT). Stereotactic body radiation therapy (SBRT) is a possible option for treating patients ineligible for BT. Patients and Methods: From October 2012 to July 2020, nine women with cervical cancer received SBRT to high-risk volumes. The Kaplan–Meier method was used to estimate the rates of overall and disease-free survival. Results: The median age was 52 years; 88% of patients had squamous carcinoma. Reasons for forgoing BT were cervical canal stenosis, treatment refusal and hematological disease. The median boost dose was 18 Gy and the median dose per fraction was 6 Gy. Median follow-up was 16 months. The median survival was 24 months, the actuarial 2-year OS rate was 70%, and median disease-free survival was 11 months. One grade 3 late vaginal toxicity was reported. No acute nor late grade 4 toxicities were observed. Conclusion: SBRT boost in patients with cervical cancer ineligible for BT led to acceptable survival outcomes and a safe toxicity profile.
