2008b Background: Anaplastic oligodendrogliomas, pure (AO) and mixed (AOA), are chemosensitive tumors, especially if co-deleted for chromosomes 1p and 19q, but whether addition of CT to RT prolongs overall survival (OS), is unknown. Methods: In the RTOG 9402 Phase III trial, patients (pts) with AO/AOA were randomly assigned to PCV [procarbazine, CCNU (lomustine) and vincristine] followed by immediate RT vs. immediate RT alone. Early analysis showed no OS benefit for the PCV+RT group but combined therapy was associated with a longer progression-free survival (PFS). It also showed that the finding of 1p/19q co-deletion was associated with a longer OS independent of treatment. The current analysis has a median follow up of 11.3 years (yrs). Results: Two hundred ninety-one patients were randomized, 148 to PCV+RT and 143 to RT. PCV+RT was associated with longer PFS [2.5 vs. 1.7 yrs, hazard ratio (HR) 0.68, 95% confidence interval (CI) (0.53, 0.88), P = 0.003] and the 1p/19q co-deletion with a longer Median Survival Time (MST) [8.7 vs. 2.7 yrs, HR 0.41, 95% CI (0.30, 0.55), P < 0.001]. For the entire cohort, there was no difference in MST by treatment [4.6 yrs for PCV+RT vs. 4.7 yrs for RT, HR 0.79, 95% CI (0.60, 1.04), P = 0.1]. However, patients with 1p/19q co-deleted tumors lived much longer after PCV+RT (n = 59) than after RT (n = 67) [14.7 vs. 7.3 yrs, HR 0.59, 95% CI (0.37, 0.95), P = 0.03]. There was no difference in MST by treatment in pts without the 1p/19q co-deletion [n=137; 2.6 vs. 2.7 yrs, HR 0.85, 95% CI (0.58, 1.23), P = 0.39]. Re-operation rates upon progression were similar between treatment arms in co-deleted pts (43%, PCV+RT vs. 54%, RT) but salvage CT rates were higher in the RT arm [57% vs. 81% (P = 0.04)]. Conclusions: PCV followed by immediate RT was a highly effective therapy for patients with 1p/19q co-deleted AO/AOA. In this setting, 1p/19q co-deletion was both prognostic and predictive, and the early PFS benefit in co-deleted cases was a harbinger of their longer OS.

Abstract Purpose: Alemtuzumab (MabCampath) is a humanized monoclonal antibody that targets the CD52 antigen, which is highly expressed on most human B and T lymphocytes. Alemtuzumab has shown considerable activity in both relapsed/refractory CLL and in the frontline treatment setting. In a recent study, treatment with single-agent alemtuzumab induced MRD-negative remissions in 20% of patients with relapsed/refractory CLL (Moreton et al JCO 2005;23:2971–2979). Other studies suggest that MRD negativity can also be attained when alemtuzumab is administered as consolidation for patients with CLL who achieve incomplete initial responses to chemotherapy. Here, we report our long-term experience within a randomized phase III trial that investigates the role of alemtuzumab for consolidation therapy in patients with previously untreated CLL. Methods: Pts in complete or partial remission after induction chemotherapy, with either fludarabine (F) or fludarabine plus cyclophosphamide (FC), were randomized to receive either alemtuzumab 30 mg, 3 times a week for ≤12 wks or no further treatment. Of 21 eligible pts, who had responded to induction with F or FC (1 CR, 1 nPR, 9 PRs), 11 pts (median age: 60 years) randomized to receive alemtuzumab consolidation and 10 to the observation arm. Pts in the alemtuzumab arm received standard premedication and infection prophylaxis with famciclovir and trimethoprim/sulfamethoxazole. Results: After a median follow-up of 48 months, calculated from time of randomization within this consolidation trial, progression-free survival (PFS) was significantly improved for pts who received alemtuzumab consolidation compared to those who received no further treatment (median PFS not reached versus 20.6 months, P = 0.004). PFS from the beginning of induction therapy with F or FC is also significantly greater for patients in the alemtuzumab consolidation arm versus the observation arm. So far, 3 of 11 pts presented with disease progression after alemtuzumab consolidation compared with 8/10 progressing pts in the observation arm. Differences in PFS between both arms were not associated with disease stage before first line treatment, type of first line chemotherapy (F vs. FC) or response status before initiation of consolidation therapy (CR vs. nPR vs. PR). Correlations between achievement of MRD negative responses and PFS is still under investigation and is planned for presentation. With the exception of 2 patients (1 pt in each arm) all patients remain alive. The study was stopped prematurely due to severe infections (7 CTC III infections, which included 4 CMV reactivations, 1 CTC IV infection) in 7/11 patients being treated with alemtuzumab. However, these infections were successfully treated, not associated with the cumulative dose of alemtuzumab, and no late complications of consolidation therapy have been observed. Conclusions: Although based on few pts due to incomplete accrual, long-term PFS was significantly prolonged in patients with CLL receiving alemtuzumab consolidation after first line chemotherapy with F or FC. An ongoing phase I/II trial of the GCLLSG (CLL2i) is currently evaluating the optimal dose and schedule of alemtuzumab in CLL pts after fludarabine-based chemotherapy.

570 Introduction: Capecitabine (Xeloda [X]) shows synergy with taxanes and adding X to docetaxel (T) extends overall survival (OS), response rate (RR) and progression free-survival (PFS) beyond T alone. Sequential single-agent therapy could confer convenience benefits and may be more appropriate than combination chemotherapy for some pts. Methods: Pts with anthracycline-pretreated MBC received 3-weekly cycles of 1 of the following regimens: X→taxane (X 1250mg/m2 bid d1–14, followed after progression (PD) by T 100mg/m2 or paclitaxel [P] 175mg/m2 day 1; X+P (X 825mg/m2 bid days 1–14 + P 175mg/m2 day 1) or X+T (X 825mg/m2 bid days 1–14 + T 75mg/m2 day 1). Results: Of the 368 pts enrolled, 91 are either still on therapy or not evaluable. The table shows baseline characteristics, efficacy and safety in evaluable pts. Median follow up is 15.5 months. Median doses for X in each arm (1st cycle vs. 8th cycle, mg/m2 bid): 1218 vs. 1054; 948 vs. 900; 846 vs. 751. Median doses for P and T (1st cycle vs. 8th cycle, mg/m2): 173 vs. 169 and 75 vs. 72, respectively. In the X→taxane arm, 58 pts (64%) received sequential taxane; the remainder did not receive a taxane, either because they were still on X, had CR or had rapid PD. Conclusions: RR is higher with XP and XT, but PFS and OS are similar at a median follow-up of 15.5 months. All regimens were well tolerated with minimal grade 4 AEs. Because there is no clear superiority of sequential vs. combined therapy, pt characteristics are likely to be used to decide which regimen is the most appropriate.

Purpose The Gruppo Oncologico Nord Ovest (GONO) conducted a phase III study comparing fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI [irinotecan 165 mg/m2 day 1, oxaliplatin 85 mg/m2 day 1, leucovorin 200 mg/m2 day 1, fluorouracil 3,200 mg/m2 48-hour continuous infusion starting on day 1, every 2 weeks]) with infusional fluorouracil, leucovorin, and irinotecan (FOLFIRI). Methods Selection criteria included unresectable metastatic colorectal cancer, age 18 to 75 years, and no prior chemotherapy for advanced disease. The primary end point was response rate (RR). Results A total of 244 patients were randomly assigned. An increase of grade 2 to 3 peripheral neurotoxicity (0% v 19%; P < .001), and grade 3 to 4 neutropenia (28% v 50%; P < .001) were observed in the FOLFOXIRI arm. The incidence of febrile neutropenia (3% v 5%) and grade 3 to 4 diarrhea (12% v 20%) were not significantly different. Responses, as assessed by investigators, were, for FOLFIRI and FOLFOXIRI, respectively, complete, 6% and 8%; and partial, 35% and 58%, (RR, 41% v 66%; P = .0002). RR confirmed by an external panel was 34% versus 60% (P < .0001). The R0 secondary resection rate of metastases was greater in the FOLFOXIRI arm (6% v 15%; P = .033, among all 244 patients; and 12% v 36%; P = .017 among patients with liver metastases only). Progression-free survival (PFS) and overall survival (OS) were both significantly improved in the FOLFOXIRI arm (median PFS, 6.9 v 9.8 months; hazard ratio [HR], 0.63; P = .0006; median OS, 16.7 v 22.6 months; HR, 0.70; P = .032). Conclusion The FOLFOXIRI regimen improves RR, PFS, and OS compared with FOLFIRI, with an increased, but manageable, toxicity in patients with metastatic colorectal cancer with favorable prognostic characteristics. Further studies of FOLFOXIRI in combination with targeted agents and in the neoadjuvant setting are warranted.

Purpose There is no consensus on the optimal systemic treatment of patients with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue. The IELSG-19 phase III study, to our knowledge, was the first such study to address the question of first-line treatment in a randomized trial. Patients and Methods Eligible patients were initially randomly assigned (1:1 ratio) to receive either chlorambucil monotherapy (6 mg/m2/d orally on weeks 1 to 6, 9 to 10, 13 to 14, 17 to 18, and 21 to 22) or a combination of chlorambucil (same schedule as above) and rituximab (375 mg/m2 intravenously on day 1 of weeks 1, 2, 3, 4, 9, 13, 17, and 21). After the planned enrollment of 252 patients, the protocol was amended to continue with a three-arm design (1:1:6 ratio), with a new arm that included rituximab alone (same schedule as the combination arm) and with a final sample size of 454 patients. The main end point was event-free survival (EFS). Analysis of chlorambucil versus the combination arm was performed and reported separately before any analysis of the third arm. Results At a median follow-up of 7.4 years, addition of rituximab to chlorambucil led to significantly better EFS (hazard ratio, 0.54; 95% CI, 0.38 to 0.77). EFS at 5 years was 51% (95% CI, 42 to 60) with chlorambucil alone, 50% (95% CI, 42 to 59) with rituximab alone, and 68% (95% CI, 60 to 76) with the combination ( P = .0009). Progression-free survival was also significantly better with the combination ( P = .0119). Five-year overall survival was approximately 90% in each arm. All treatments were well tolerated. No unexpected toxicities were recorded. Conclusion Rituximab in combination with chlorambucil demonstrated superior efficacy in mucosa-associated lymphoid tissue lymphoma; however, improvements in EFS and progression-free survival did not translate into longer overall survival.

Abstract Abstract 3978 Background: Bortezomib alone and in combination with other agents has shown great promise in the treatment of AL amyloidosis in various preliminary open studies. Here we present our experience at the UK National Amyloidosis Centre with CVD in both the upfront and relapsed setting. Patients and Methods: The primary cohort comprises 37 patients referred to the National Amyloidosis Centre in London from 2006–2010. 27 patients had cardiac involvement by 2005 consensus criteria. 29 had renal involvement, 10 had liver involvement and 26 had other organs involved. Complete information for staging by the Mayo clinic criteria was available in 34 patients, and 47% were stage III based on values obtained prior to the initiation of CVD (23% of upfront patients and 62% of relapsed patients). The recommended CVD regimen was as follows: bortezomib 1.0 mg/m2 IV days 1, 4, 8, 11 (increase to 1.3 mg/m2 if well tolerated) cyclophosphamide 350 mg/m2 po days 1, 8, 15 dexamethasone 20 mg po days 1, 4, 8, 11 (increase to 40 mg if well tolerated) with an aim to deliver 6 cycles of treatment. Dose modifications were at the discretion of the treating haematologist. We aimed to assess response at 6 months (m). Haematologic and organ responses were defined as per the 2005 consensus criteria. The dFLC response (difference between the involved and uninvolved free light chain) was defined as the percent difference in the dFLC at the start of therapy and at response assessment and was considered assessable if the baseline dFLC was >50mg/L. A dFLC of 50–90% defined a partial response, and a dFLC of >90% defined a VGPR. Progression free survival (PFS) was calculated by the Kaplan-Meier method and calculated from the start of CVD until relapse, death or last follow-up. Statistical analysis was performed using SPSS version 19. Approval for analysis and publication was obtained from the institutional review board at the University College London, and written consent was obtained from all patients. Results: Median follow-up was 13.3m. Median time to assessment was 5.9m. Median number of cycles given was 4.9. All 37 patients were assessable by haematologic response criteria, 29 of whom were assessable for dFLC response. Overall hematologic response rate (RR) was 78.4% (CR = 35.1%). A VGPR was attained 48.3% of patients with an overall dFLC RR of 79.3%. 14 patients were treated with CVD upfront with a RR of 85.7% (CR = 64.3%, VGPR = 66.7%). 23 patients were treated in the relapse setting and the RR was 73.9% (CR = 17.4%, VGPR = 35.3%). Clonal response is detailed in table 1. 26 patients were assessable for a BNP response based on a pre-treatment NT-proBNP > 660 ng/L. BNP responses were seen in 8 patients (31%), stable disease in 14 (54%) and progression in 4 (15%). Of the entire cohort only one death was reported and there were no treatment related mortalities. The time to maximal response was 3.8m (3.0m and 3.8m in patients treated upfront and at relapse respectively). Median PFS has not been reached. The estimated 2-year PFS was 55.6% for the entire cohort, 69.6% for patients treated upfront and 43.8% for those treated at relapse. Attaining a CR correlated with a significant improvement in progression free survival compared with those who had not (median PFS not reached vs. 23.1m respectively, P = 0.029; figure 1A). Attaining a VGPR also correlated with an improved PFS compared with those who had not (median PFS not reached vs. 13.2m respectively, P = 0.003; figure 1B). Conclusion: This retrospective series lends further support to the use of bortezomib containing regimens in the treatment of AL amyloidosis. CVD is a safe and effective treatment option supporting similar findings in other small retrospective series, particularly when used in the upfront setting. This is, to our knowledge, the first series reporting PFS with this regimen. In addition, it confirms the importance of achieving a CR for improved survival outcomes and further validates the dFLC response as an important treatment endpoint. CVD is an attractive treatment combination for patients with AL amyloidosis many of whom are transplant ineligible due to advanced disease. Larger phase III studies are warranted and are underway.

5512 Background: One cycle of adjuvant BEP has shown superiority in recurrence free survival over RPLND in patients (pts) with clinical stage (CS) I nonseminomatous germ cell tumor of the testis (NSGCT) (JCO 2008). We report recurrences and late toxicities of this randomized trial after 13 yrs of follow-up (FU). Methods: Questionnaires of 382 unselected pts with CS I NSGCT treated within a phase III trial comparing recurrence rate after 1 cycle of adjuvant BEP (arm A) vs. RPLND (arm B) were evaluated regarding recurrences and late toxicity. Overall (OS) and progression free survival (PFS) was calculated by Kaplan-Meier and arms were compared using logrank test. Categorial data were analyzed by chi-square test (PRISM v8). Results: In each arm 191 pts were analyzed as intention-to-treat with a median FU of 13.75 yrs (0-22.9 yrs); 3/191 pts (1.6 %) in arm A and 16/191 pts (8.4 %) in arm B had a recurrence. 20-yrs PFS in arm A / B was 97 % (CI 96-99 %) / 92 % (CI 90-95 %), ( p = .0049). 20-yrs OS in arm A / B was 90 % (CI 86-94 %) / 88 % (CI 86-94 %), ( p = .83). 23/382 (6 %) pts have died, 22/23 not related to testis cancer, 1/23 died of a recurrence in arm B. 8/191 pts (4.2 %) in arm A and 4/191 pts (2.1 %) in arm B showed metachronous secondary testis cancer ( p = .26). 5/191 pts (2.6 %) in arm A and 4/191 pts (2.1 %) in arm B developed other malignancies. 170/382 questionnaires were evaluable (arm A: 95; arm B: 75). 45 pts were lost to FU. There were no significant differences comparing both treatment arms regarding potentially treatment-related late toxicities. However, excluding pre-existing complaints, ototoxicity (9/95 (9 %) vs. 4/75 (5 %) pts, p = .31) was reported more frequently in arm A. Excluding pre-existing neurological conditions, peripheral neuropathy of all grades was more frequently reported in arm A (15/95 pts; 16 % vs. 9/75 pts; 12 % pts; p = .48). Retrograde ejaculation occurred more frequently after RPLND (9/95 pts; 9% vs. 18/75 pts; 24 %, p = .01). Conclusions: After more than 13 yrs of FU, recurrences in non-risk factor selected pts with CS I NSGCT remain to be significantly more frequent with RPLND. No excess mortality due to secondary malignancies was observed. Late toxicities did not differ between 1 cycle of BEP and RPLND. Only retrograde ejaculation was observed significantly more frequent after RPLND. With long-term observation, 1 cycle of BEP has not only a high efficacy to prevent recurrence but also seems to be tolerated without clinically relevant long-term toxicity.

Purpose The randomized HD2000 trial compared six cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), four escalated plus two standard cycles of BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone), and six cycles of COPP-EBV-CAD (cyclophosphamide, lomustine, vindesine, melphalan, prednisone, epidoxorubicin, vincristine, procarbazine, vinblastine, and bleomycin; CEC) in patients with advanced-stage Hodgkin lymphoma. After a median follow-up of 42 months, patients who received BEACOPP were reported to have experienced better progression-free survival (PFS) but not better overall survival (OS) results than those receiving ABVD. We here report a post hoc analysis of this trial after a median follow-up of 10 years. Patients and Methods Three hundred seven patients were enrolled, 295 of whom were evaluable. At the time of our analysis, the median follow-up for the entire group was 120 months (range, 4 to 169 months). Results The 10-year PFS results for the ABVD, BEACOPP, and CEC arms were 69%, 75%, and 76%, respectively; corresponding OS results were 85%, 84%, and 86%. Overall, 13 second malignancies were reported: one in the ABVD arm and six each in the BEACOPP and CEC arms. The cumulative risk of developing second malignancies at 10 years was 0.9%, 6.6%, and 6% with ABVD, BEACOPP, and CEC, respectively; the risk with either BEACOPP or CEC was significantly higher than that reported with ABVD (P = .027 and .02, respectively). Conclusion With these mature results, we confirm that patients with advanced Hodgkin lymphoma have similar OS results when treated with ABVD, BEACOPP, or CEC. However, with longer follow-up, we were not able to confirm the superiority of BEACOPP over ABVD in terms of PFS, mainly because of higher mortality rates resulting from second malignancies observed after treatment with BEACOPP and CEC.

PurposeTo evaluate the association of germ-line polymorphisms of genes that may impact treatment outcome of platinum and fluorouracil combination chemotherapy in advanced gastric cancer (AGC).Patients and MethodsBlood samples of 156 patients enrolled onto a phase III study comparing fluorouracil, leucovorin, and oxaliplatin with fluorouracil, leucovorin, and cisplatin were collected. Polymorphisms within genes of TS, MTHFR, MTR, OPRT, XPD, ERCC1, XRCC1, XPA, GSTP1, GSTT1, and GSTM1 were genotyped using polymerase chain reaction–based techniques.ResultsMedian overall survival (OS) was 11.8 months (95% CI, 9.75 to 13.79 months) and median progression-free survival (PFS) was 5.8 months (95% CI, 4.99 to 6.61 months). The TS-3R/+6 haplotype (P = .004), the GSTT1 deletion polymorphism (P = .015), and genotypes of OPRT-Gly213Ala (P = .003) and XRCC1-Arg399Gln (P = .023) could be identified as independent predictors of OS. For PFS analyses, the TS-3R/+6 haplotye (P = .003) and MTR-A2756G (P = .01) were identified as independent positive predictors. The association between the GSTT1 deletion polymorphism and PFS showed only borderline significance (P = .053). Treatment related hematotoxicity in terms of grade 3/4 leukopenia was lowest among TS-3R/+6 haplotype carriers (P = .037). Grade 3/4 neutropenia was directly associated with the MTR-2756G/G genotype (P = .011), GSTP1-105Ile/Ile genotype (P = .02), and with the ERCC1-118T/8092C-haplotype (P = .042). In addition, significant associations between GSTP1-105Ile/Ile genotype and neurotoxicity and between the XPD-Asn312/751Gln haplotype and nephrotoxicity could be identified (P = .028 and P = .005, respectively).ConclusionThese findings underline the hypothesis that germ-line polymorphisms may play an important role in individualizing chemotherapy in AGC and deserve further prospective evaluation in AGC patients.
