Abstract   To assess safety, feasibility and efficacy of an intensified preoperative IMRT and concomitant carboplatin and paclitaxel-based chemotherapy (Carbo/Tax CT) in patients (pts) with locally advanced esophageal cancer (LAEC) treated at our Institution. Methods a retrospective analysis of toxicity (CTCAE 4.03), progression free survival (PFS) and overall survival (OS) of pts affected by LAEC, treated with preoperative intensified radiotherapy (IMRT) and weekly concurrent carboplatin and paclitaxel-based chemotherapy (CT) according to the CROSS trial, between February 2016 and October 2019, at the Centro di Riferimento Oncologico, Aviano (CRO). Results Sixty-nine consecutive pts, 57(82.6%) males, were treated. The median age was 69 yrs (38–85), the ECOG PS 0–2. All pts underwent concurrent chemoradiotherapy, IMRT technique, 45 Gy/25 to PTV1 (primary tumor volume + regional nodes), a simultaneous boost from 52.5Gy to 54Gy to PTV2 (gross tumor volume) and weekly concurrent carboplatin (AUC2) and paclitaxel (50 mg/m2). Induction CT was administered to 17 pts. All pts completed RT with median 4 (1–5) CT cycles. Median follow-up was 8 months (4–17); 2-yr PFS and OS were 49.0% and 80.3%, respectively. At 2 yrs, local recurrence rate was 8.4% (CI 95%: 2.6%–18.8%). Conclusion Preoperative intensified IMRT with concomitant Carbo/Tax CT in pts with LAEC appears safe and feasible with promising oncological outcome and needs to be confirmed in a larger series of pts.

4064 Background: Weekly irinotecan, cisplatin, and concurrent radiation therapy is a well-tolerated, active regimen in locally advanced esophageal cancer. (Ilson. JCO 2003) Cetuximab, an EGFR inhibitor, is a potent radiation sensitizer in head and neck cancer. (Bonner. Proc ASCO 2004) Methods: In this phase II trial, patients (pts) with T2–4N0–1M0–1A esophageal adenocarcinoma (A) or squamous cell carcinoma (S) receive 5040 cGy/28 fractions of radiation therapy (RT) and concurrent weekly cisplatin 30mg/m2 plus irinotecan 65 mg/m2 on weeks 1, 2, 4, and 5, followed by surgery 4–8 weeks after completion of RT. Additionally, pts receive weekly infusions of cetuximab 250 mg during RT, up to one week before surgery, and for 6 months following surgery. Results: Seventeen pts have been entered: male: female = 14:3, median age 54, ECOG PS 0:1 = 6:11, A:S = 17:0, stage IIA:IIB:III:IVA = 6:1:8:2, tumor location-esophagus-mid:lower:gastroesophageal junction = 1:4:12, >10% weight loss-yes:no = 8:9. Of 17 pts entered, 15 pts have proceeded to surgery, 1 pt died from Aspergillus infection resulting in respiratory failure and sepsis, and 1 pt is pending surgery. Of the 15 pts who underwent surgery, 2 (13%) had a complete pathologic response; pathologic stage for other pts: 0 = 1, I = 3, IIA = 3, IIB = 1, III = 4, IV = 1. Grade III/IV toxicity (17 pts) was: diarrhea 9 pts, neutropenia 9 pts, febrile neutropenia 5 pts, anorexia 5 pts, vomiting 4 pts, fatigue 3 pts, mucositis 1 pt. Chemotherapy dose attenuation was required for diarrhea in 5 pts, for neutropenia in 4 pts, and for folliculitis in 1 pt. One patient was removed from study during week 6 for prolonged diarrhea/ dehydration. Due to the 2-step design of the trial, accrual is on hold pending a 3rd required pathologic CR in the first 17 patients. Conclusions: Compared to other trials of irinotecan, cisplatin, radiation therapy, and surgery in similar groups of esophageal cancer patients, early results for this combination with cetuximab suggest a lower complete response rate and higher overall toxicity. Additional data will be available at ASCO. Supported by Bristol-Myers Squibb. No significant financial relationships to disclose.

203 Background: Although tri-modality therapy is an acceptable standard of care in patients with locally advanced esophageal cancer, data regarding patterns of failure is lacking. We report bi-institutional patterns of failure experience treating patients using tri-modality therapy. Methods: Following IRB approval, we retrospectively reviewed all pts who underwent chemoradiation followed by esophagectomy at two NCI-designated cancer centers from 2000-2013. Patient and treatment factors were analyzed for failure patterns. First failure sites were categorized as local, regional nodal, or distant. Statistical analysis was performed using Fisher’s exact test and non-parametric Wilcoxon rank-sum test. Results: A total of 132 patients met the inclusion criteria with a median age of 62 (range 36-80) and median follow-up of 28 months (range 4-128). The majority of patients had T3 (82%), N1 (64%), or M0/M1a (92%) disease. At the time of last follow-up there were a total of 6 (4.5%) local, 13 (10%) regional nodal, and 32 (23.5%) distant failures. Local failure was correlated with fewer lymph nodes assessed (p=0.01) and close or positive margins (p<0.01). Regional nodal failure was correlated with fewer lymph nodes assessed (p<0.01) and smaller pre-treatment tumor size (p=0.04). Distant recurrence was correlated with post-treatment nodal stage (p<0.01), peri-neural invasion (p=0.03), negative margins (p=0.02), ulceration (p=0.02), incomplete response (p<0.01), post-treatment PET SUV (p=0.05), 3D-CRT (0.053), metastatic disease at diagnosis (p<0.01) and post-treatment metastatic disease (p<0.01). No other patient, tumor, or treatment factor was correlated with treatment failure. Conclusions: Per our bi-institutional experience, patient, tumor, and treatment factors may predict for failure in patients undergoing tri-modality therapy for locally advanced esophageal cancer. Further data is needed to identify patterns of failure in these patients.

150 Background: The prognostic value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) has not yet been defined in locally advanced esophageal cancer (LAEC). This study aims to elucidate the prognostic role of PET/CT for patients treated with neoadjuvant chemoradiation (CRT) followed by esophagectomy. Methods: We retrospectively evaluated patients with LAEC treated from 2006 to 2014 with neoadjuvant CRT followed by esophagectomy. 86 patients had pre-CRT and post CRT PET/CT scans performed at our institution. These scans were imported into an image analysis program. PET parameters maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), mean standardized uptake value (SUVmean), and peak standardized uptake value (SUVpeak) were recorded for both pre-CRT and post-CRT scans. MTV was defined using a previously described liver method. The correlation of these parameters with pathologic complete response (pCR) and clinical outcomes was analyzed using binomial logistic regression and cox regression. Results: Pre-CRT MTV < 33.6 (median value) was significantly predictive of pCR (p = 0.019, OR = 3.064). An ROC curve was produced to determine a binary cutoff of 35.8, yielding a higher specificity (62.3% vs. 59%) and the same sensitivity (72.7%), increasing the significance to p = 0.010, OR = 3.378. The ratio of postMTV/preMTV (MTVr) was calculated. MTVr > 0.2857 (median value) was significantly predictive of distant metastasis (DM) after esophagectomy (p = 0.018, OR = 3.680). An ROC curve was produced to determine a binary cutoff of 0.301, which increased specificity from 57.1% to 60.3%, and maintained the same sensitivity at 81.3%, increasing the significance to p = 0.014, OR = 3.815. SUVmax, mean and peak were not predictive. Conclusions: Pre CRT MTV was predictive of pCR and MTVr was predictive of DM. Our data suggests that MTV is superior to SUVmax, mean and peak in predicting for response to treatment in LAEC. Further study is needed to determine if Pre CRT MTV and change in MTV can help define which patients will most benefit from esophagectomy and/ or adjuvant chemotherapy.

PURPOSE Whether dosimetric advantages of proton beam therapy (PBT) translate to improved clinical outcomes compared with intensity-modulated radiation therapy (IMRT) remains unclear. This randomized trial compared total toxicity burden (TTB) and progression-free survival (PFS) between these modalities for esophageal cancer. METHODS This phase IIB trial randomly assigned patients to PBT or IMRT (50.4 Gy), stratified for histology, resectability, induction chemotherapy, and stage. The prespecified coprimary end points were TTB and PFS. TTB, a composite score of 11 distinct adverse events (AEs), including common toxicities as well as postoperative complications (POCs) in operated patients, quantified the extent of AE severity experienced over the duration of 1 year following treatment. The trial was conducted using Bayesian group sequential design with three planned interim analyses at 33%, 50%, and 67% of expected accrual (adjusted for follow-up). RESULTS This trial (commenced April 2012) was approved for closure and analysis upon activation of NRG-GI006 in March 2019, which occurred immediately prior to the planned 67% interim analysis. Altogether, 145 patients were randomly assigned (72 IMRT, 73 PBT), and 107 patients (61 IMRT, 46 PBT) were evaluable. Median follow-up was 44.1 months. Fifty-one patients (30 IMRT, 21 PBT) underwent esophagectomy; 80% of PBT was passive scattering. The posterior mean TTB was 2.3 times higher for IMRT (39.9; 95% highest posterior density interval, 26.2-54.9) than PBT (17.4; 10.5-25.0). The mean POC score was 7.6 times higher for IMRT (19.1; 7.3-32.3) versus PBT (2.5; 0.3-5.2). The posterior probability that mean TTB was lower for PBT compared with IMRT was 0.9989, which exceeded the trial’s stopping boundary of 0.9942 at the 67% interim analysis. The 3-year PFS rate (50.8% v 51.2%) and 3-year overall survival rates (44.5% v 44.5%) were similar. CONCLUSION For locally advanced esophageal cancer, PBT reduced the risk and severity of AEs compared with IMRT while maintaining similar PFS.
