PURPOSE We report the results of the final phase I/II program in glioblastoma (GBM) multiforme patients using only hyperfractionated irradiation and intravenous iododeoxyuridine (IdUrd). METHODS For a decade we investigated halogenated pyrimidine radiosensitizers in an effort to exploit the potential for differential uptake of thymidine analogs between proliferating tumor and normal brain tissues. Trials began with bromodeoxyuridine (BrdUrd) but were changed to IdUrd when the latter proved less photosensitizing. A series of dose-escalating pilot trials led to treatment at a maximum-tolerated dose (MTD) of IdUrd of 1,000 mg/m2/d for two separate 14-day courses, one during the initial radiation field and one during the cone down. The radiotherapy also evolved over time and was hyperfractionated in all cases reported. Over 5 years we accrued 45 patients into the final hyperfractionated, 1,000 mg/m2/d scheme. We report here results on only the patients with minimum follow-up of 1 year (90% had at least 2 years of follow-up) or until death. RESULTS The results do not indicate a significant benefit for use of sensitizers, as compared with other contemporary and aggressive types of radiation treatment. The median survival has been 11 months, with a 2-year actuarial survival of 9%. As yet, there are no survivors at 3 years. Tumor biopsies at craniotomy showed relatively low sensitizer incorporation. CONCLUSION The failure of radiosensitizers combined with radiation therapy to show major benefit may be due to patient selection but appears also to be related to the combined problems of poor drug penetration/uptake into tumor, tumor-cell heterogeneity, and a high inherent cellular radioresistance of GBM.

PURPOSE The Children's Cancer Group conducted a phase I trial of temozolomide stratified by prior craniospinal irradiation (CSI). PATIENTS AND METHODS Children and adolescents with recurrent or progressive cancer were enrolled. Temozolomide was administered orally daily for 5 days, with subsequent courses administered every 21 to 28 days after full hematologic recovery. Dose levels tested included 100, 150, 180, 215, 245, and 260 mg/m2 daily. RESULTS Twenty-seven patients on the non-CSI stratum were assessable for hematologic toxicity. During the first three dose levels (100, 150, and 180 mg/m2 daily), only grades 1 and 2 hematologic toxicity occurred. One patient at 215 mg/m2 daily had grade 3 hematologic toxicity. Three of eight patients (38%) treated at 245 to 260 mg/m2 daily had dose-limiting toxicity (DLT), which included both neutropenia and thrombocytopenia. Twenty-two patients on the CSI stratum were assessable for hematologic toxicity. Hematologic DLT occurred in one of six patients (17%) at 100 mg/m2 daily and in two of four patients (50%) at 215 mg/m2 daily. No nonhematologic DLT occurred; nausea and vomiting occurred in more than half of the patients. After two courses of temozolomide, 10 patients had stable disease (SD), and three patients had a partial response (PR), one of whom subsequently had a complete response (CR) that persists through 24 months of follow-up. CONCLUSION The maximum-tolerated dose (MTD) of temozolomide for children and adolescents without prior CSI is 215 mg/m2 daily and for those with prior CSI is 180 mg/m2 daily for 5 days, with subsequent courses that begin on day 28. Temozolomide is well tolerated and should undergo phase II testing in children and adolescents.

PURPOSE: Preclinical studies show a significant increase in the ratio of the radiosensitizer bromodeoxyuridine (BUdR) in tumors versus the intestinal mucosa during the drug elimination period, compared with the ratio during drug infusion. We constructed a phase I study in patients with locally advanced cervix cancer, using alternating cycles of BUdR and radiation therapy (RT). PATIENTS AND METHODS: Eighteen patients with stage IIB to IVA cervix cancer participated. A treatment cycle consisted of a 4-day BUdR infusion followed by a week of pelvic RT, 15 Gy twice daily in 1.5-Gy fractions. After three cycles, additional BUdR was infused, followed by brachytherapy. The fraction of thymidine replaced by BUdR and the fraction of cells incorporating BUdR were determined in rectal mucosa and tumor biopsies at the end of the first BUdR infusion (day 5), at the middle of the first RT week (day 10), and at the time of brachytherapy. RESULTS: Dose-limiting toxicity was observed in one of 16 patients receiving 1,000 mg/m2/d × 4 days and inboth patients receiving 1,333 mg/m2/d × 4 days each cycle. After a median follow-up of 39 months, 12 patients (66%) were free of pelvic disease and nine (50%) were alive and disease free. The ratio of tumor to rectum BUdR incorporation averaged 1.5 to 1.8 and did not differ significantly between day 5 and day 10. A trend toward reduced ratio was observed at brachytherapy. Drug-containing cells in rectal biopsies migrated from the crypts to the mucosal surface. CONCLUSION: In this schedule, 1,000 mg/m2/d is the maximum-tolerated dose of BUdR. BUdR incorporation levels in tumors were consistent with clinically significant radiosensitization. The migration of BUdR-containing rectal mucosa cells from the crypts to the surface at the time of RT suggests that this regimen may offer a relative sparing of the mucosa from radiosensitization.

8050 Background: Concurrent chemoradiotherapy has been regarded as one of the standard management for localized nasal NKTCL. However, its long-term efficacy and toxicity is not known. Methods: The JCOG0211 trial is a phase I/II study of concurrent chemoradiotherapy consisting of radiotherapy (RT) of 50 Gy and 3 cycles of DeVIC (carboplatin, etoposide, ifosfamide, dexamethasone) for newly diagnosed, localized nasal NKTCL (JCO 2009). Patients (Pts) with newly diagnosed, localized diseases (IE & contiguous IIE with cervical node involvement) who were 20-69 yrs of age with PS 0-2 were eligible. 3-D conformal RT planning with a wide margin (+ 2 cm to the gross tumor, the entire nasal cavity and the nasopharynx) and a 2-step cone down were required. 33 pts were enrolled in the study, 27 of whom were treated with RT and a 2/3-dose of DeVIC, which was selected as the recommended phase II dose in the preceding phase I portion of the trial. All pts completed RT without any protocol violations. Long-term follow-up results on overall survival (OS), progression-free survival (PFS) and toxicity were evaluated. Results: The median follow-up was 69 months (range, 62-96). The pt (N=33) characteristics were as follows: median age 54 yrs (range, 21-68); stage IIE 33%; B symptom (+) 36%; elevated serum LDH 21%. %5-yr OS and PFS were 73% (95%CI, 54-85%) and 67% (95%CI, 48-80%), respectively. 11 pts (33%) experienced disease recurrence. Two achieved a 2nd CR by salvage chemotherapies followed by allogeneic stem cell transplantation, and the remaining 9 pts died of disease. There was no observed death and disease progression after 34 and 31 months, respectively. One pt experienced Grade 3 irregular menstruation for 3 years. No other Grade 3 or 4 late non-RT-associated adverse events (AEs) were observed. One pt received plastic surgery due to Grade 4 RT dermatitis. No other Grade 3 or greater RT-associated late AEs were encountered. Conclusions: Both survival benefit and disease control from concurrent chemoradiotherapy with RT and DeVIC are maintained during a 5-yr follow-up, indicating the excellent efficacy of this approach as a first-line therapy for localized nasal NKTCL. Long-term toxicity is acceptable.

8030 Background: The immune checkpoint receptor programmed death-1 (PD-1) negatively regulates T-cell activation. Nivolumab, a PD-1 receptor blocking antibody, was evaluated in a phase 1 study in pts with various tumors including NSCLC (Topalian et al, NEJM 2012;366:2443). Methods: Pts with ≥1 prior chemotherapy regimen received nivolumab (1-10 mg/kg IV Q2W) for ≤12 cycles (4 doses/8W cycle) or until discontinuation criteria were met. We report initial overall survival (OS) and updated safety and response data for NSCLC pts. Results: 127 pts evaluable for safety received nivolumab at 1, 3, or 10 mg/kg as of July 2012. Common drug-related AEs were decreased appetite (9%), anemia (8%), diarrhea, nausea, and pruritus (7% each). The most common G3/4 AEs were fatigue, pneumonitis, and elevated AST (2% each). Two drug-related deaths from pneumonitis occurred early in the trial and led to increased monitoring without further deaths from pneumonitis. Median OS (mOS) across all dose cohorts was 9.2 mo and 9.6 mo for squamous (sq) and non-sq NSCLC, respectively. mOS was not reached at the 3 mg/kg dose (phase 3 dose) for either histology. Sustained OS was observed, with 44%/ 41% and 44%/ 17% of pts (sq/non-sq) alive at 1 and 2 years, respectively (Table). Prolonged ORs occurred in both histologies (Table). Conclusions: In this long-term follow-up of a phase I trial, nivolumab had an acceptable safety profile and showed an encouraging sustained OS benefit across histologies in previously treated advanced NSCLC. Follow-up through a Feb 2013 data cut (≥1 yr follow-up for all pts) will be provided at presentation. Clinical trial information: NCT00730639. [Table: see text]

60 Background: Pre-operative radiotherapy (PreORT) improves local control in various cancer types, and has become an established oncologic treatment strategy. During 2001-2004, we conducted a phase I pilot study assessing the role of short-course PreORT for men with unfavourable intermediate- and high-risk localized prostate cancer (PCa). We present long-term follow-up toxicity and oncologic outcomes. Methods: Eligible patients had histologically proven PCa, cT1-T2N0M0, PSA > 15-35 ng/ml with any Gleason score, or PSA 10-15 ng/ml with Gleason score ≥7. Patients received 25 Gy in five consecutive daily fractions to the prostate, followed by radical prostatectomy (RadP) within 14 days after RT completion. Primary outcomes were intra-operative morbidity, and late genitourinary (GU) and gastrointestinal (GI) toxicities. Acute toxicity was assessed during radiotherapy treatment on daily basis using RTOG grade scoring scale. Patients were assessed post-RadP clinically and with PSA at 1 and 6 months, and every 6 months. Intra- and Post-RadP toxicity was documented prospectively and scored as per Common Terminology Criteria for Adverse Events v4.0. Biochemical failure (BF) was determined based on two consecutive post-RadP PSA > 0.2 ng/ml. Results: Fifteen patients were enrolled; 14 patients completed PreORT followed by RadP, which also included bilateral lymph node dissections in 13 cases. Median follow-up was 12.2 years (range 6.7-16.3 years). Late GU toxicity was common, with 2 patients (14.3%) experiencing G2 toxicity, and 6 patients (42.8%) G3 toxicity. There were no G4-5 late GU toxicity. Late GI toxicity was infrequent, with only 1 patient (7.1%) experiencing transient G2 proctitis. At last follow-up, 8 (57.1%) and 6 (42.8%) patients experienced BF and metastatic disease recurrence, respectively. Conclusions: The use of PreORT in men with high-risk PCa is associated with unexpected high-rates of late GU toxicity. Future studies examining the role of RT pre-RadP must cautiously select RT technique and dose schedule. Importantly, long-term follow-up data is essential to fully determine the therapeutic index of PreORT in the management of localized PCa. Clinical trial information: NCT00252447.
