7717 Background: Accelerated fractionation proved beneficial in INT0096, but the total dose was low and local recurrence was high with higher acute grade (Gr.) 3+ esophagitis. RTOG 0239 was a phase II trial to improve local control and survival with LSCLC with acceptable acute Gr. 3+ esophagitis using accelerated high dose TRT and concurrent cisplatin/etoposide. This is the first report of acute Gr.3+ esophagitis and Gr.5 toxicities. Methods: Patients (pts) with LSCLC without pleural effusion, contralateral hilar or contralateral supraclavicular nodes and PS 0–1 were enrolled. TRT was given to large fields to 28.8 Gy at 1.8 Gy per fraction, 5 days per week for 16 fractions followed by BID with large field in AM, boost in PM, then off-cord boost BID for last 5 days, all at 1.8 Gy per fx for a total dose of 61.2 Gy in 34 fx in 5 weeks. Concurrent chemotherapy was started with TRT with cisplatin, 60 mg/m2 i.v. day 1; etoposide, 120 mg/m2 i.v. day 1; etoposide, 240 mg/m2 p.o. per day or 120 mg/m2 i.v. per day on days 2 or 3. Cycles were repeated q.3 wks during and for 2 cycles after TRT. Pts who have achieved complete response one month after completion of 4 cycles of chemotherapy were asked to participate in a prophylactic cranial irradiation (PCI) study. Common toxicity criteria (CTC) 2.0 was used for acute toxicity. Results: From 10/2003 to 5/2006, 72 pts were accrued. Median age was 63 yrs with 52% females. Survival data is still maturing. Acute toxicity information is available for 68 pts. Eleven pts (16%) experienced acute Gr. 3 and 1 pt (1%) had acute Gr. 4 esophagitis. 47 pts (69%) had grade 4 blood/bone marrow toxicities. There were 2 (3%) Gr. 5 toxicities reported [1 infection with neutropenia; 1 pulmonary (pneumonia)]. Conclusions: This accelerated high dose TRT with concurrent chemotherapy for LSCLC resulted in 17% acute Gr.3+ esophagitis compared to 27% with BID TRT with 45Gy in 3 weeks by INT0096. There were 3% grade 5 toxicities. This preliminary report suggests that RTOG-0239 has tolerable toxicity. The acute Gr3+ esophageal toxicity correlated with V20 and V40 will be presented. Pts continue to be followed for the primary endpoint of 2-year survival. No significant financial relationships to disclose.

Abstract Objective: The objective of this study is comparision of local and distant control rates with high-dose versus standard-dose radiotherapy along with concurrent chemotherapy in esophageal cancer – a prospective randomized study. Materials and Methods: Histologically proven Stage I–III patients with carcinoma esophagus were randomized into two groups. One group has been treated with standard-dose radiotherapy, i.e., a total dose of 50.4 Gy (1.8 Gy/day, 28#, 5 days/week). The other group (study arm) has received high-dose radiotherapy, i.e. a total dose of 64.8 Gy (1.8 Gy/day, 36#, 5 days/week). Both groups have received 2 cycles of 3 weekly concurrent chemotherapy (cisplatin 75 mg/m[2] on day 1 and 5-fluorouracil 750 mg/m[2] continuous intravenous infusion over 24 h on day 1–4). Follow-up response evaluation was done by both endoscopy and computed tomography scan after 6–8 weeks and after 2 months thereafter. Results: Out of a total of 28 patients, 68% showed a complete response, 14% showed partial response, and 18% patients developed progressive disease at first and subsequent follow up (median follow-up of 21 months). Among the complete response patients, rates were higher in high-dose group compared to standard-dose radiotherapy group (71% vs. 64%, P = 0.38). Treatment-related toxicities were acceptable in both groups. Conclusion: High-dose radiotherapy with concurrent chemotherapy seems to be more effective with acceptable toxicity in our study. However, further follow-up and large sample size may be required to validate the current study conclusion.

Abstract Background: 166Ho-DOTMP is a beta-emitting radiophosphonate that localizes specifically to the bone surfaces and can deliver high dose radiation both to the bone and bone marrow. Follow-up data from 3 clinical trials with STR as conditioning for patients with MM undergoing autologous PBSCT are presented. Methods: In 2 Phase I/II dose-escalation trials, 83 patients received a dose of 166Ho-DOTMP STR calculated to deliver 20, 30, or 40 Gy to the red marrow; 82 pts received melphalan (140 or 200 mg/m2) ± 8 Gy TBI (n=25), followed by PBSCT. As of June, 2004, 77 subjects have been followed for at least 48 months. In a separate Phase II dosimetry trial, 12 patients received two 30 mCi tracer doses of 166Ho-DOTMP STR to determine the reproducibility of biodistribution and pharmacokinetics (PK). All pts received a 25 Gy therapy dose with concurrent IV hydration and continuous bladder irrigation, followed by 200 mg/m2 melphalan and PBSCT. These patients have been followed for at least 18 months. Results: Up to 2.3 Ci/m2, 166Ho-DOTMP STR was given in the Phase I/II trials; 29/83 (35%) patients achieved complete response (CR) and overall response rate (CR + PR) was 64% (7 pts not evaluable). The Kaplan-Meier estimate of median survival is 5.2 years for all 83 patients. In patients who are at least 4 years post transplant who achieved a CR, the survival is 74% (n=27). In patients who achieved less than a CR at least 4 years ago, the survival is 34% (n=44). Dose-related radiation-induced kidney toxicity presented in some patients more than 6 months post-therapy. The dose of 166Ho-DOTMP STR in the Phase II dosimetry trial was 550 to 860 mCi/m2, 166Ho-DOTMP. Currently, 18 months of follow-up reveals no occurrence of hemorrhagic cystitis or > Grade 2 elevated creatinine. A CR rate of 17% with an overall survival of 92%, was observed. In 10 patients who received 166Ho-DOTMP STR 750 mCi/m2 ± 10% in the Phase I/II trial, the CR rate was 40%, and the 4-year survival was 70%. Monitoring for safety and duration of response is ongoing in all 3 trials. Conclusion: Follow-up from the Phase I/II trials confirms that 166Ho-DOTMP STR provides favorable efficacy and safety as part of the conditioning regimen for patients with MM undergoing PBSCT. A Phase III, randomized multicenter study is now open to enrollment, comparing the safety and efficacy of 166Ho-DOTMP STR plus melphalan to melphalan alone as conditioning for PBSCT in subjects with primary refractory MM who have failed to respond to induction therapy, including high-dose dexamethasone, and are within 18 months of diagnosis.

7527 Background: Inter-group(IG) study 0096 showed that hyperfractionated and accelerated radiotherapy (HFXART) and concurrent etoposide/cisplatin(EP) improved 5-yr survival (26 %) for patients (pts) with limited small cell lung cancer (LSCLC) compared to daily treatment (TRT) with EP (16%), (p=0.04), HFXART/ EP still had high local failure (LF 40 %) and acute severe esophagitis (ASE) rate (27%). Radiation Therapy Oncology Group (RTOG) 0239 was developed to improve local control (LC) and overall survival (OS) without increasing ASE.Methods: Eligibility included limited stage SCLC, age ≥ 18; P.S. 0–1, with adequate hematologic, hepatic, and renal function. RT was given to large field to 28.8 Gy: 1.8 Gy/ fraction (Fx), 5 days (d) / wk for 16 Fx followed by BID with AP/PA fields in AM @ 1.8 Gy /Fx; boost with 2nd treatment in PM @ 1.8 Gy/Fx on d: 23–26; then off-cord boost, 1.8 Gy, BID, x last 5 days for a total dose of 61.2 Gy in 5 wks. EP was started on day 1 of TRT with P, 60 mg/m2 i.v; E, 120 mg/m2 i.v.; E, 240 mg/m2 p.o. d 2 and 3 or E 120 mg/m2 i.v. / d on d 2 or 3. Repeat cycle every 3 wks x 2 cycles with RT, followed by adjuvant EP alone x 2 cycles. CR pts were asked to participate in the prophylactic cranial irradiation (PCI) study RTOG 0212. RTOG 0239 was designed to detect an improvement in the 2-year survival rate from 47% to 60% with less than 30% of ASE.Results: RTOG 0239 accrued 72 pts (71 eligible) from June 20, 2003 to May 23, 2006. The median follow-up time is 19.0 months for all pts, and 30.4 months for pts still alive. The median age was 63, 52% female, 58% Zubrod PS 0. The 2 -year survival rate was 37 % [95% CI: 25.6, 47.7]. 13 pts (18 %) experienced severe esophagitis. 2 treatment related deaths (2.8%) were reported. Response rates 2 months post RX showed CR 41%, PR 39%, SD 10% and PD 6%. Locoregional control rate at two years was 80%. RT compliance was 95 %.Conclusions: RTOG 0239, AHTRT/EP for LSCLC resulted in 37% 2-year OS, 80% 2 year LC and 18% ASE. Compliance with treatment was high and treatment-related death rate was similar to other chemoradiation regimens. Although 2-year OS did not achieve 60%, excellent LC and low ASE were achieved by RTOG 0239 which became one of 3 arms in an ongoing randomized trial of LSCLC RTOG0538/CALGB30610. [Table: see text]

e16046 Background: Since the results of the RTOG 9111 trial, cisplatin based chemoradiation (CRT) has been the standard of care for LP in advanced laryngeal SCC. Recently, the role of taxanes in managing head and neck SCC has been studied. In 2002 we reported the interim results of a phase II clinical study designed to test the efficacy of P and C concurrent with RT for organ preservation in advanced L and HP SCC. Here we report the long term survival and LP rates. Methods: Eligible patients had untreated advanced L and HP SCC, stage T3N0 or higher and suitable for radical total laryngectomy. Treatment consisted of weekly P (30 mg/m2) and C (20 mg/m2) concurrent to RT up to 7040 cGy in 180 cGy/day fractions. Response evaluation was performed at 5040 cGy and at 4 weeks after completing RT. Salvage surgery was planned for patients not responding at 5040 cGy, residual tumor at the end of RT or at the time of local recurrence. Neck dissection was planned for clinically positive neck (cN1-3). Results: Between 06/1999 and 10/2001, 48 patients were enrolled in a single institution (35 L; 13 HP), 40 male and 8 female with a 58-year median age (39-74). The majority had T3 (64%) N1-3 (52%) disease and 38% needed tracheostomy prior to treatment. Grade (G) 3 and 4 mucositis was noted in 27% of patients, G 3-4 odynophagia in 50%, G 3-4 radiodermatitis in 35% and G 3-4 leucopenia in 13%, with no treatment related death. Two patients needed salvage surgery, one after 5040 cGy and one after 7040 cGy. The complete response rate to treatment was 95%. At a median follow up of 66 months the LP rate at 2 and 5 years were 88% and 54%, respectively. Recurrence free survival (RFS) was 51% at 2 and 47% at 5 years and overall survival (OS) was 81% and 52% at 2 and 5 years, respectively. Conclusions: The finding of similar LP rate and survival compared to the recent reports of high dose cisplatin CRT and neoadjuvant 3 drug CT followed by CRT in an advanced disease population suggests a role for platinum plus taxane as a radiosensitizer regimen in this scenario with acceptable toxicity, but further evaluation in a direct comparative trial with the standard regimen is needed.

25 Background: Multi-parametric MRI (mpMRI) of PCa uses advanced sequences to detect aggressive, high grade and bulky lesions. Given known advantages of hypofractionated radiotherapy (RT) to treat PCa (low a/b ratio), we conducted a phase II trial to escalate a high dose to mpMRI lesion(s) via Image-Guided (IG)-RT/Volumetric Arc Therapy (VMAT)/Stereotactic Body Radiotherapy (SBRT) technology. We present the acute toxicity results of this novel approach. Methods: 22 pts with mpMRI lesion(s) were prospectively treated to a course of IGRT/VMAT to the prostate & seminal vesicle +/- pelvic lymph nodes (PLN) to a dose of 45 Gy in 25 fractions followed by SBRT boost, 18 Gy in 3 fraction to the prostate with a simultaneous integrated boost 21 Gy in 3 fractions (EQD2 = 85.2 Gy using a/b 3 or 93.4 Gy using a/b 1.5) to the mpMRI prostatic lesion(s). Placement of 3 polymer based fiducial markers visible in both CT and MRI for image co-registration and treatment guidance was performed. Genitourinary (GU) and gastrointestinal (GI) adverse events (AE) were scored using CTCAE v4. DSMC approved reporting of acute AE results prior to completion of trial accrual as an interim safety assessment prior to final trial accrual. Results: Median age was 66.5 years (range: 57-80). All patients had PI-RADS grade 3-5 mpMRI lesion(s); 41.0%, 45.4% and 13.6% having 1, 2 and 3 lesions respectively. Ten (45%) pts had Gleason Score (GS) 8-10 and 12 had GS 7 disease. Median PSA was 8.97 (range: 4.0-77.9). Eleven (50%), 10 (46%), and 1 (5%) pts had stage T1, T2, and T3 tumor, respectively. Nine pts received treatment to the PLN and 15 received androgen deprivation therapy. All patients completed the protocol treatment without reporting acute GI or GU AEs grade ≥3 during treatment or at follow up. Grade 2 GI (diarrhea) and GU toxicity (frequency) was seen in 2 (9%) and 9 (41%) pts, respectively, during treatment. Of the 16 pts (71%) with least 3 months follow-up all grade 2 GI and 55.5% GU toxicities had resolved. Conclusions: Early results of this prospective Phase II study suggest that high-dose RT for localized PCa via mpMRI-guided RT/VMAT and SBRT boost is tolerable with a favorable acute toxicity profile.

Purpose Although dose-intensive strategies or high-dose therapy induction followed by autologous stem-cell transplantation have improved the outcome for patients with mantle-cell lymphoma (MCL), most eventually relapse and subsequently respond poorly to additional therapy. Bortezomib (in the United States) and temsirolimus (in Europe) are currently the only two treatments approved for relapsed disease. Lenalidomide is an immunomodulatory agent with proven tumoricidal and antiproliferative activity in MCL. The MCL-001 (EMERGE) trial is a global, multicenter phase II study examining the safety and efficacy of lenalidomide in patients who had relapsed or were refractory to bortezomib. Patients and Methods Lenalidomide 25 mg orally was administered on days 1 through 21 every 28 days until disease progression or intolerance. Primary end points were overall response rate (ORR) and duration of response (DOR); secondary end points included complete response (CR) rate, progression-free survival (PFS), overall survival (OS), and safety. Results In all, 134 patients were enrolled with a median age of 67 years and a median of four prior therapies (range, two to 10 prior therapies). The ORR was 28% (7.5% CR/CR unconfirmed) with rapid time to response (median, 2.2 months) and a median DOR of 16.6 months (95% CI, 7.7 to 26.7 months). Median PFS was 4.0 months (95% CI, 3.6 to 5.6 months), and median OS was 19.0 months (95% CI, 12.5 to 23.9 months). The most common grade 3 to 4 adverse events were neutropenia (43%), thrombocytopenia (28%), anemia (11%), pneumonia (8%), and fatigue (7%). Conclusion The MCL-001 study demonstrated durable efficacy of lenalidomide with a predictable safety profile in heavily pretreated patients with MCL who had all relapsed or progressed after or were refractory to bortezomib.
