e15550 Background: Locally advanced esophageal cancer (LAEC) has a 5-year survival of < 30 %. Most patients (pts) fail after curative intent tri-modality treatment with distant metastatic disease. This phase II trial aims to determine if adjuvant targeted therapy, after neoadjuvant CRT plus surgery for resectable LAEC, may impact on systemic disease without significant toxicity. Methods: Pts with LAEC of the thoracic esophagus or gastroesophageal junction, ECOG PS 0,1 and surgical candidates treated with: preoperative Irinotecan (65mg/m2 initially, ammended to 50mg/m2) + Cisplatin (30mg/m2) on weeks 1,2,4,5,7,8 + concurrent conformal radiotherapy (50Gy/25 fractions) on weeks 4–8. Esophagectomy during weeks 15–18. Sunitinib 37.5mg daily (escalating to 50mg daily if tolerated) commenced 4–12 weeks post surgery, for 1 year. Primary endpoint is feasibility and efficacy of adjuvant sunitinib. Planned sample size 36pts. Results: 30pts enrolled from 11/06 to 12/08. Median age 64 yr (43–71), male: 22, adenocarcinoma: squamous 22:6; 10 pts stage IIA, 5 IIB and 13 III. 2 pts excluded with positive PET scan. 28 pts completed CRT - 18 pts (64%) received ≥80% of planned chemotherapy dose, 23 pts (82%) received full radiation dose. Grade 3/4 toxicity included: neutropenia (17/28), diarrhea (7/28), dehydration (4/28), febrile neutropenia (FN) (3/28) and nausea (2/28). 2 deaths on chemotherapy (1 bacterial meningitis, 1 FN) leading to irinotecan dose- reduction. Dysphagia improved in 14/23 pts during CRT. 18 pts have undergone esophagectomy. Complete pathological response in 4 (22%), downstaging in 3 (17%), stable disease in 11 (61%). 2 pts unresectable (metastases at laparotomy). 1 post-operative death due to pulmonary embolus. 9 pts have commenced sunitinib, 6 maintained at starting dose of 37.5mg; 2 dose reductions; 1 discontinued with poor wound healing. Grade 3 toxicity included: leukopenia (2/9), hand-foot reaction (1/9) and depression (1/9). Conclusions: In LAEC, induction Irinotecan/Cisplatin and radiotherapy followed by esophagectomy is associated with a significant but manageable toxicity profile. Early initiation of sunitinib is feasible and well-tolerated. Updated results to be presented. No significant financial relationships to disclose.

4570 Background: Cetuximab significantly enhances efficacy of radiotherapy and chemotherapy in head and neck cancer. We investigated the safety and feasibility of adding cetuximab to neoadjuvant chemoradiation of locally advanced esophageal cancer. Methods: Pts with resectable, locally advanced squamous cell carcinoma (SCC) or adenocarcinoma (AC) of the thoracic esophagus or gastroesophageal junction (staged by EUS, CT and PET scan) were treated with 2 cycles of induction chemotherapy (docetaxel 75mg/m2, cisplatin 75mg/m2 q3w and weekly cetuximab 250mg/m2), followed by concomitant chemo- immuno-radiation therapy (CIRT: docetaxel 20mg/m2, cisplatin 25mg/m2 and cetuximab 250mg/m2 weekly five times concomitant with 45 Gy radiotherapy in 25 fractions); followed by surgery 4–8 weeks later. The phase I part consisted of 2 cohorts of 7 patients each, without and with docetaxel during CIRT, respectively. Interpatient dose-escalation (adding docetaxel during CIRT) was possible if < 2 out of 7 pts of the 1st cohort experienced limiting toxicity. Having finished the phase 1 part, 13 additional patients were treated with docetaxel-containing CIRT in a phase II part. Pathological response was evaluated according to the Mandard classification. Results: 27 pts from 12 institutions were included. As of today, results from 20 pts are available (cohort 1: 7, cohort 2: 7, phase ll : 6). Median age was 64yrs (range 47–71). 11 AC; 9 SCC. 19 pts (95%) completed CIRT (1 pt stopped treatment during induction therapy due to sepsis). 17 pts underwent resection (no surgery: 1pt for PD, 1pt for cardiac reasons). Grade 3 toxicities during CIRT included anorexia 15%, dysphagia/esophagitis 15%, fatigue 10%, nausea 10%, pruritus 5%, dehydration 5%, nail changes 5% and rash 5% .1 pt suffered from pulmonary embolism. 13 pts (65%, intention-to-treat) showed a complete or near complete pathological remission (cohort 1: 5, cohort 2: 4, phase II: 4). Conclusions: Adding cetuximab to preoperative chemoradiation for esophageal cancer is safe and feasible in a community-based multicenter setting. Antineoplastic activity is encouraging with 65% pathological responders. [Table: see text]

4056 Background: Esophagectomy (E) for locally advanced esophageal cancer (LAEC) yields limited survival; this phase II trial assess feasibility and efficacy of induction chemo-radiotherapy followed by E. Methods: Patients (pts) with LAEC of the thoracic esophagus (TE) or gastroesophageal junction (GEJ), ECOG PS ≤ 2 and surgical candidates underwent POP I (65mg/m2) + C (30mg/m2) on weeks 1,2,4,5,7,8 + concurrent conformal radiotherapy (40Gy/20 fractions (F) during wk 4–7) and external beam boost (10Gy/5F on wk 8); E was performed on wk 12–16 after restaging. Pts receiving 75% of POP chemotherapy were eligible for pathologic (p) evaluation; planned sample size 36 nonM1A pts. Results: 52 pts enrolled from 11/02 to 12/05, mean age 60 yr (33–79), male:40, GEJ:TE/15:37; 37 adenocarcinoma, 13 SCC, 2 other; 13 pts were stage IIA, 7 IIB, 22 III, and 10 IVA. Toxicity during POP treatment included ANC (G3/4:36%), febrile neutropenia (9%), diarrhea (G3:9%), nausea (G3:6%), esophagitis (G3:2%) and anorexia (G3/4:15%); 3 pts stopped treatment due to toxicity, 2 withdrew, 2 progressed becoming non-operable, 1 died of a stroke and 1 from central line sepsis. Clinical response by RECIST was CR:2%, PR:30%, SD:62% and PD in 6%. Dysphagia improved or resolved in 34/47 pts (72%) during POP treatment. Of 43 evaluable pts, 41 underwent E, achieving R0 resection in 98% (1 refused E, 1 pending). Perioperative complications included anastomotic leak (23%), Afib (21%), pneumonia (21%), delirium (10%) and aspiration (10%); 1 pt died from aspiration. 7 pts (17%) achieved pCR, 2 of whom were pretreatment clinical stage IIA, 1 IIb and 4 III; downstaging occurred in 3/7 pts; 15 pts (36.6%) achieved minimal residual disease, 15 (36.6%) pPR, and 4 (9.8%) pSD. At a median (med) follow-up of 15.2 months (1.3–34.5m), 16/52 patients died (med & 2yr overall survival (OS) of 29 m & 66%). Of 41 resected pts, 17 recurred (med & 2yr disease free survival (DFS) of 20m & 46%) of whom 10 died of progression (med & 2-yr OS of 29m & 68.4%). 2yr DFS & OS was 83% & 86% in pCR vs 41% & 76% in non-pCR. Conclusion: In LAEC, induction I/C and radiotherapy followed by E is associated with 72% dysphagia improvement, a significant but manageable toxicity profile, and encouraging survival compared to historical controls.

Purpose The objective of this phase II trial was to assess the efficacy and toxicity of weekly paclitaxel for patients with metastatic or unresectable angiosarcoma. Patients and Methods Thirty patients were entered onto the study from April 2005 through October 2006. Paclitaxel was administered intravenously as a 60-minute infusion at a dose of 80 mg/m2 on days 1, 8, and 15 of a 4-week cycle. The primary end point was the nonprogression rate after two cycles. Results The progression-free survival rates after 2 and 4 months were 74% and 45%, respectively. With a median follow-up of 8 months, the median time to progression was 4 months and the median overall survival was 8 months. The progression-free survival rate was similar in patients pretreated with chemotherapy and in chemotherapy-naïve patients (77% v 71%). Three patients with locally advanced breast angiosarcoma presented partial response, which enabled a secondary curative-intent surgery with complete histologic response in two cases. One toxic death occurred as a result of a thrombocytopenia episode. Six patients presented with grade 3 toxicities and one patient presented with a grade 4 toxicity. Anemia and fatigue were the most frequently reported toxicities. Conclusion Weekly paclitaxel at the dose schedule used in the current study was well tolerated and demonstrated clinical benefit.

Purpose: To identify the maximum-tolerated dose and dose-limiting toxicity (DLT) of weekly irinotecan combined with cisplatin and radiation in esophageal cancer. Patients and Methods: Nineteen patients with clinical stage II to III esophageal squamous cell or adenocarcinoma were treated on this phase I trial. Induction chemotherapy with weekly cisplatin 30 mg/m2 and irinotecan 65 mg/m2 was administered for four treatments during weeks 1 to 5. Radiotherapy was delivered weeks 8 to 13 in 1.8-Gy daily fractions to a dose of 50.4 Gy. Cisplatin 30 mg/m2 and escalating-dose irinotecan (40, 50, 65, and 80 mg/m2) were administered on days 1, 8, 22, and 29 of radiotherapy. DLT was defined as a 2-week delay in radiotherapy for grade 3 to 4 toxicity. Results: Minimal toxicity was observed during chemoradiotherapy, with no grade 3 or 4 esophagitis, diarrhea, or stomatitis. DLT caused by myelosuppression was seen in two of six patients treated at the 80-mg/m2 dose level, thus irinotecan 65 mg/m2 was defined as the recommended phase II dose. Dysphagia improved or resolved after induction chemotherapy in 13 (81%) of 16 patients who reported dysphagia before therapy. Only one patient (5%) required a feeding tube. Six complete responses (32%) were observed, including four pathologic complete responses in 15 patients selected to undergo surgery (27%). Conclusion: Cisplatin, irinotecan, and concurrent radiotherapy can be administered on a convenient schedule with relatively minimal toxicity and an acceptable rate of complete response in esophageal cancer. Further phase II evaluation of this regimen is ongoing. A phase III comparison to fluorouracil or taxane-containing chemoradiotherapy should be considered.

e14596 Background: S-1 is an orally active fluoropyrimidine that enhances the efficacy of radiotherapy (RT) and has low gastrointestinal toxicity. Our previous phase II study demonstrated that definitive chemoradiotherapy (CRT) with S-1 and cisplatin was well-tolerated and had favorable activity for locally advanced esophageal cancer (Iwase H et al, Proc. ASCO 2011, Abst 4034). The present study was a phase II trial of combination therapy using S-1, cisplatin, and RT for distant metastatic esophageal cancer (DMEC). Methods: S-1 (80 mg/m2/day) was given orally for 14 consecutive days from Day 1 and cisplatin (70 mg/m2) was administered on Day 14, both with 3 weeks of RT (2.0 Gy per traction) 5 times per week for the primary lesion and metastases in the neck, which initiated on Day 1. One Cycle equals 5 weeks, 2 weeks of chemotherapy concurrent with 3 weeks of RT followed by 2 weeks of complete rest. After 2 cycles, only chemotherapy with S-1 and cisplatin were administered. Results: Forty-one patients with DMEC (Stage IVb) were enrolled between March 2002 and February 2011. 37/male7/female, median age 67.5 years (48-82). The median survival follow-up time was 16.6 months and 37 patients (90.2%) completed the combination treatment. The most common adverse event was neutropenia. Grades 3 and 4 neutropenia were observed in 29.2% and 12.2%, respectively. In general, non-hematological adverse events were mild and the most common were Grade 2 nausea (34.1%), esophageal pain and oral mucositis (17.1% each), and renal dysfunction (9.8%). The overall response rate was 65.9% comprising 93.2% in the primary lesion, 60% in the liver metastasis, 64.3.% in the lung, 54.5% in the distant lymph node, 83.3% in the regional lymph node metastasis, and 50% in the other distant metastases. Thirty-nine patients (88.6%) showed improvement in their dysphagia score. The median progression-free and overall survival durations were 5.3 [95% confidence interval (CI), 4.1 to 6.0] and 13.1 months (95% CI, 9.8 to 15.6), respectively. Conclusions: Combination therapy using S-1, cisplatin, and RT has a promising safety and efficacy profile. Potentially, this regimen could become the baseline treatment for patients with DMEC.

Background: The use of HER2 targeting therapy has revolutionized the treatment of HER2 positive breast cancers. Here, we investigate whether a sequential approach to dual HER2 blockade of lapatinib followed by trastuzumab will result in improved clinical outcomes.Methods: This was a single institution, open label, single arm, phase II trial in women with HER2 positive breast cancer. Volunteers were treated with sequential neoadjuvant doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) (AC) for 4 cycles followed by docetaxel (100 mg/m2) concurrent with lapatinib (1,250 mg) (TL) daily for 21 days for four cycles before definitive surgery. The primary end point was pathologic complete response (pCR).Results: The study accrued only 21 of the 71 planned patients from 2/28/2007 to 5/25/2010. All patients (100%) experienced down staging. The pCR rate was 41% (7/18). 11 patients had tumor size of T3 or greater, 3 of which experienced pCR and only 1 underwent breast conservation (lumpectomy). The most common hematologic AE (all grades) was anemia 17/21 (81%). There were no incidences of grade 3 or 4 anemia. 10 of 21 (48%) patients experience a non-hematologic grade 3 AE. The most common non-hematologic AEs (all grades) were irregular menses 20/21 (95%) and hand-foot-skin reactions 20/21 (95%). No increase cardiac abnormalities were noted. The DFS at data cut off was 87.5%.Conclusion: The provocative pCR and DFS results in this high risk locally advanced patient population should be viewed with caution given results of the Adjuvant Lapatinib And/Or Trastuzumab Treatment Optimisation study (ALTTO) clinical trial.

4562 Background: The role of preoperative therapy in patients (pts) with locally advanced esophageal cancer remains unclear. Non-randomized and randomized studies were often performed in single and highly specialized centers. The purpose of this study was to investigate 1) the efficacy and toxicity of preoperative docetaxel-cisplatin together with radiation therapy (RT) 2) the feasibility of a complex preoperative strategy in a community-based multicenter setting. Methods: Eligibility criteria: resectable, locally advanced (uT3 or uN1, T4 if deemed resectable) squamous cell carcinoma (SCC) or adenocarcinoma (AC) of the thoracic esophagus or gastroesophageal junction (Siewert type l); staged by EUS, CT and PET scan; age 18–70y; PS <2; normal organ functions. Treatment: 2 cycles of docetaxel 75mg/m2 and cisplatin 75mg/m2 q3w, followed by weekly x5 docetaxel 20mg/m2 and cisplatin 25mg/m2 with concomitant 45 Gy RT in 25 fractions; surgery 3- 8 weeks after RT. A two stage-design was used with two primary endpoints: 1) efficacy (TRG : tumor regression grade ); 2) feasibility (successful completion of entire therapy and being alive 30 days after surgery). Results: 66 pts, 56 males, were included from 11 institutions; median age 61y (35–70y); AC 53%; SCC 46%; 53 pts (80%) completed the preoperative therapy, underwent resection and were alive 30 days after surgery; 10 pts (15%) had no resection (4 progressive disease, 4 medical reasons, 2 patient’s refusal). Of 56 (85%) pts who had surgery, 51 pts had RO-resection (91%), 5 pts (9%) died due to complications after surgery (3 after > 30 days). Conclusion: Our trimodality treatment shows encouraging antineoplastic activity with 57% histopathological responders (TRG1 and 2) and acceptable feasibility in a community-based multicenter setting.
