2014 Background: Treatment of anaplastic oligodendroglial tumors is controversial. Early results of randomized trials suggest chemotherapy (CT) with procarbazine-lomustine-vincristine (PCV) before or after radiotherapy (RT) improves progression-free but not overall survival (OS) versus RT alone. It is unknown if CT alone affects outcome versus CT&RT, or if temozolomide (TMZ) compares favorably with PCV. Methods: We retrospectively identified adults with newly diagnosed anaplastic oligodendroglioma (AO) or oligo-astrocytoma (AOA) seen at 17 medical centers from 1981–2007 exclusive of phase III or bone marrow transplant trials. Data were updated January 1, 2009. Survivals were estimated by Kaplan-Meier method and compared with log-rank. Results: There were 1054 patients: 594 men, 460 women; median age 42 (18–88); 661 with AO, 443 with AOA. Treatment was: observation (82, 8%), RT alone (n = 210, 20%), RT then chemotherapy (283, 27%), RT + CT concurrently (118, 11%), CT alone (205, 19%), CT then RT (137, 13%), or other (19, 2%). Median time to progression (TTP) and OS were 2.8 and 6.5 years, respectively, with median follow up of 4.1 years (0.03–20.8) on surviving patients (n = 560, 53%). 1p19q co-deletion was observed in 292 (48%) and no deletion in 232 (38%) of 606 tested tumors. Co-deletion predicted longer median TTP (4.2 vs. 1.8 years for no deletion, p = 0.0002) and OS (8.4 vs. 3.3 years, p < 0.0001). Median TTP was longer following CT&RT (sequential or concurrent) than CT alone (3.7 vs. 2.6 years, p = 0.0007), but median OS did not differ (6.6 vs. 7.1 years, p = 0.8); co-deletion was more common with CT alone than CT&RT (p < 0.0001, χ2), although restricting analysis of CT&RT versus CT to the co-deletion cohort yielded analogous results (median TTP 7.2 vs. 3.8 years, p = 0.011; OS 7.9 vs. 10.4 years, p = 0.26). Median TTP was longer following PCV alone (7.6 years, n = 17) than TMZ alone (3.3 years, n = 65) with co-deletion (p < 0.02); median OS was also longer (not reached, vs. 7.1 years), but did not reach statistical significance (p = 0.07 log-rank). Conclusions: 1p19q co-deletion predicted improved outcome. Treatment strategies varied widely. CT alone did not appear to shorten OS versus CT&RT. PCV may be superior in efficacy to TMZ. Multivariate analyses and additional 1p19q testing are in progress. [Table: see text]

Long Term Follow Up

Purpose Anaplastic oligodendroglioma are chemotherapy-sensitive tumors. We now present the long-term follow-up findings of a randomized phase III study on the addition of six cycles of procarbazine, lomustine, and vincristine (PCV) chemotherapy to radiotherapy (RT). Patients and Methods Adult patients with newly diagnosed anaplastic oligodendroglial tumors were randomly assigned to either 59.4 Gy of RT or the same RT followed by six cycles of adjuvant PCV. An exploratory analysis of the correlation between 1p/19q status and survival was part of the study. Retrospectively, the methylation status of the methyl-guanine methyl transferase gene promoter and the mutational status of the isocitrate dehydrogenase (IDH) gene were determined. The primary end points were overall survival (OS) and progression-free survival based on intent-to-treat analysis. Results A total of 368 patients were enrolled. With a median follow-up of 140 months, OS in the RT/PCV arm was significantly longer (42.3 v 30.6 months in the RT arm, hazard ratio [HR], 0.75; 95% CI, 0.60 to 0.95). In the 80 patients with a 1p/19q codeletion, OS was increased, with a trend toward more benefit from adjuvant PCV (OS not reached in the RT/PCV group v 112 months in the RT group; HR, 0.56; 95% CI, 0.31 to 1.03). IDH mutational status was also of prognostic significance. Conclusion The addition of six cycles of PCV after 59.4 Gy of RT increases both OS and PFS in anaplastic oligodendroglial tumors. 1p/19q-codeleted tumors derive more benefit from adjuvant PCV compared with non–1p/19q-deleted tumors.

5001 Background: Tak is an oral selective nonsteroidal 17, 20-lyase inhibitor that blocks the synthesis of gonadal and adrenal androgens. We evaluated the clinical benefit of Tak with ADT in pts with newly diagnosed mHSPC. Methods: Pts with mHSPC with a Zubrod performance status (PS) of 0-2 and a PSA of ≥ 2 ng/ml were randomized 1:1 to ADT+Tak (300 mg twice daily) or ADT+Bic (50 mg daily). Stratification factors included PS (0-1 vs ≥2), extent of disease (minimal vs extensive), and receipt of ADT prior to registration (yes vs no). The primary endpoint was overall survival (OS). Secondary endpoints were progression free survival (PFS; based on PSA, imaging or clinical progression), PSA at 7 months (≤0.2 vs 0.2 < PSA; ≤-4 vs. > 4 ng/ml) and adverse event (AE) profile. With 2.75 yrs to accrue 1,186 eligible pts and 3 additional yrs of follow-up, we would have 90% power to determine a 33% improvement in OS from 54 to 72 mos (1-sided α = 0.025). A final analysis was pre-specified after 523 deaths using a 1-sided α = 0.022 to account for interim analyses. Results: Between 3/2013 and 7/2017, 1,313 pts were randomized and 1,279 were included in the intention-to-treat (ITT) analysis (32 pts were ineligible and 2 pts withdrew consent). Median age was 68 yrs and 10% of subjects were Black. Median PSA was 30 ng/mL (range 2-6710) and 49% of pts had extensive disease. After a median follow-up of 4.9 yrs, PFS and PSA response were significantly improved with Tak over Bic but no significant improvement in OS was observed (Table). More grade 3/4 AEs occurred in Tak vs. Bic arms (43% vs. 14%), and included hypertension (20% vs. 5%) and fatigue (5% vs. 2%). Five pts in Tak and 1 pt in the Bic arm had grade 5 AE. Conclusions: Despite clinically meaningful improvement in various outcome measures with Tak+ADT over Bic+ADT in this representative population of mHSPC, the improvement in OS did not meet the pre-specified criteria for statistical significance. The median OS of 70 mos in the control arm (standard ADT) was higher than that reported in contemporary phase 3 trials in this setting, and 16 mos higher than originally estimated. This trial sets a new landmark for survival estimates when pts with mHSPC have access to multiple approved subsequent life-prolonging therapies.

AbstractEarly results of the randomized placebo-controlled SORAML trial showed that, in patients with newly diagnosed acute myeloid leukaemia (AML), sorafenib led to a significant improvement in event-free (EFS) and relapse-free survival (RFS). In order to describe second-line treatments and their implications on overall survival (OS), we performed a study after a median follow-up time of 78 months. Newly diagnosed fit AML patients aged ≤60 years received sorafenib (n = 134) or placebo (n = 133) in addition to standard chemotherapy and as maintenance treatment. The 5-year EFS was 41 versus 27% (HR 0.68; p = 0.011) and 5-year RFS was 53 versus 36% (HR 0.64; p = 0.035). Allogeneic stem cell transplantation (allo SCT) was performed in 88% of the relapsed patients. Four years after salvage allo SCT, the cumulative incidence of relapse was 54 versus 35%, and OS was 32 versus 50%. The 5-year OS from randomization in all study patients was 61 versus 53% (HR 0.82; p = 0.282). In conclusion, the addition of sorafenib to chemotherapy led to a significant prolongation of EFS and RFS. Although the OS benefit did not reach statistical significance, these results confirm the antileukaemic activity of sorafenib.

Purpose Until recently, melphalan and prednisone were the standards of care in elderly patients with multiple myeloma. The addition of thalidomide to this combination demonstrated a survival benefit for patients age 65 to 75 years. This randomized, placebo-controlled, phase III trial investigated the efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed myeloma. Patients and Methods Between April 2002 and December 2006, 232 previously untreated patients with myeloma, age 75 years or older, were enrolled and 229 were randomly assigned to treatment. All patients received melphalan (0.2 mg/kg/d) plus prednisone (2 mg/kg/d) for 12 courses (day 1 to 4) every 6 weeks. Patients were randomly assigned to receive 100 mg/d of oral thalidomide (n = 113) or placebo (n = 116), continuously for 72 weeks. The primary end point was overall survival. Results After a median follow-up of 47.5 months, overall survival was significantly longer in patients who received melphalan and prednisone plus thalidomide compared with those who received melphalan and prednisone plus placebo (median, 44.0 v 29.1 months; P = .028). Progression-free survival was significantly prolonged in the melphalan and prednisone plus thalidomide group (median, 24.1 v 18.5 months; P = .001). Two adverse events were significantly increased in the melphalan and prednisone plus thalidomide group: grade 2 to 4 peripheral neuropathy (20% v 5% in the melphalan and prednisone plus placebo group; P < .001) and grade 3 to 4 neutropenia (23% v 9%; P = .003). Conclusion This trial confirms the superiority of the combination melphalan and prednisone plus thalidomide over melphalan and prednisone alone for prolonging survival in very elderly patients with newly diagnosed myeloma. Toxicity was acceptable.

Abstract BACKGROUND Between 1995 and 2002 the EORTC Brain Tumor Group conducted a prospective phase III study on adjuvant procarbazine, CCNU and vincristine (PCV) chemotherapy in anaplastic oligodendroglioma (AOD). A mature follow-up presented in 2012 showed survival benefit of the addition of PCV, in particular in 1p/19q co-deleted tumors and tumors with MGMT promoter methylation. We now present very long term follow-up. MATERIALS AND METHODS Patients were eligible if locally diagnosed with a newly diagnosed AOD. They were randomized between radiotherapy (RT, 33 x 1.8 Gy) and the same RT followed by 6 cycles PCV (RT/PCV). Primary endpoints were overall survival (OS) and progression free survival (PFS). 1p/19q status (FISH) was determined in 300 patient. Kaplan- Meier technique and Cox modeling were used for long term survival analysis. Primary analyses were adjusted for known prognostic factors. For other analyses no adjustment was performed. RESULTS With 368 patients included, a median follow-up of 18.4 years and 307 (83%) survival events, median and 20-year survival after RT/PCV versus RT alone were 42.3 mo and 16.8% vs 30.6 months and 10.1% (HR 0.78; 95% CI (0.63, 0.98), adjusted p=0.06). Eighty patients were 1p/19q codel of which 26 (33%) were still alive, in this subgroup median and 20-year survival after RT/PCV versus RT alone were 14 years and 37.1% versus 9.3 years and 13.6% (HR 0.60, 95% CI (0.35, 1.03), unadjusted p=0.06). Twenty year PFS in 1p/19q codel was 31.3% in RT/PCV treated patients and 10.8% in RT only treated patients (HR 0.49, 95% CI (0.29, 0.83), unadjusted p=0.007). In the 1p/19q codel subgroup age, WHO PS and necrosis at pathology were identified to be of independent prognostic value for OS. CONCLUSION This long term analysis confirms the earlier conclusions and provides data on long term survival in this patient group. In 1p/19q codel patients treated with RT/PCV, the 20-year PFS and OS rates are 31% and 37% respectively.

Abstract Design/Methods: We recently demonstrated in a phase III trial that the addition of rituximab to each of 8 cycles of CVP (R-CVP) chemotherapy significantly improves the clinical outcome of previously untreated patients with stage III/IV CD20 positive follicular NHL when compared to CVP alone (Marcus et al., Blood2005; 105: 1417–23). A multivariate Cox regression analysis of time to progression or death (TTP) showed a treatment benefit in all patient subgroups according to baseline risk factors, except for patients with a baseline hemoglobin level below normal. We now present an updated analysis of all major trial endpoints with 42 months follow-up (FU). Results: A total of 321 patients (median age 53 years) were recruited (159 CVP, 162 R-CVP). Approximately half of the patients had high-risk disease according to the Follicular Lymphoma International Prognostic Index (FLIPI, score 3–5). The median TTP was more than doubled for patients receiving R-CVP compared to CVP alone (33.6 months vs 14.5 months, p&lt;0.0001). Median time to new lymphoma treatment or death (TNLT) was 12.3 months in the CVP group and nearly quadrupled to 46.3 months in the R-CVP group (p&lt;0.0001). Superior response rates for R-CVP were confirmed (CR+CRu rate 41% vs 11%, p&lt;0.0001) with a median response duration (DR) of 13.5 months in the CVP arm versus 37.7 months in the R-CVP arm. Median disease free survival (DFS) in complete responders was 44.8 months for patients receiving R-CVP and 20.5 months in patients receiving CVP alone (p=0.0005). Thirty-five patients in the CVP arm and 23 patients in the R-CVP arm have died. Kaplan-Meier estimates of 3-year OS rates were 81% in the CVP arm and 89% in the R-CVP (p=0.07). Importantly, significantly more patients receiving CVP died due to lymphoma progression compared to patients receiving R-CVP (25 vs 12 deaths, p=0.02). Subgroup analysis for TTP, ORR, DR and OS according to risk factors at baseline are ongoing and will be presented. Conclusion: With longer FU, the combination of 8 cycles of rituximab with CVP chemotherapy continues to provide a major benefit as first line treatment for patients with advanced stage follicular NHL.

Abstract Background: In newly diagnosed myeloma patients the combination of bortezomib with melphalan-prednisone (VMP) was superior to MP. In relapsed-refractory patients the 4 drug combination of bortezomib-melphalan-prednisone-thalidomide (VMPT) induced a high proportion of complete responses (CR). Methods: Newly diagnosed myeloma patients (N=393) older than 65 years, from 58 centers in Italy, were randomly assigned to receive VMPT (N=193) or VMP (N=200). Initially, patients were treated with nine 6-week cycles of VMPT (bortezomib 1.3 mg/m2 days 1,4,8,11,22,25,29,32 in cycles 1–4 and days 1,8,22,29 in cycles 5–9; melphalan 9 mg/m2 days 1–4; prednisone 60 mg/m2 days 1–4 and thalidomide 50 mg days 1–42, followed by bortezomib 1.3 mg/m2 every 15 days and thalidomide 50 mg/day as maintenance) or VMP (bortezomib, melphalan and prednisone at the same doses and schedules previously described without maintenance). In March 2007, the protocol was amended: both VMPT and VMP schedules were changed to nine 5-week cycles and bortezomib schedule was modified to weekly administration (bortezomib 1.3 mg/m2 days 1,8,15,22 in cycles 1–9). Primary end-point was progression-free survival (PFS). Results: Patient characteristics were similar in both groups: median age was 71 years, 23% of patients were aged > 75 years. Patients who received at least 1 cycle were evaluated: 152 patients for VMPT (62 received bortezomib bi-weekly infusion and 90 weekly infusion) and 152 patients for VMP (62 received bortezomib bi-weekly infusion and 90 weekly infusion). Data were analyzed in intention-to-treat. The very good partial response (VGPR) rate was higher in the VMPT group (55% versus 42%, p=0.02), including a CR rate of 31% in the VMPT group and 16% in the VMP group (p=0.003). In the subgroup treated with weekly infusion of bortezomib, VGPR was 59% for VMPT and 37% for VMP (p=0.004), including 28% CR for VMPT and 10% for VMP (p=0.004). Subgroup analyses did not show any statistical difference between responses and either age, B2-microglobulin or chromosomal abnormalities, such as del13, t(4;14), t(14;16) and del17. After a median follow-up of 13.6 months, the 2-year PFS was 83.9% in the VMPT group and 75.7% in the VMP group (HR=0.73, 95% CI 0.38–1.42, p=0.35). In patients who received weekly infusion of bortezomib, the 2-year PFS was 86.8% in the VMPT group and 78.1% in the VMP group (HR=0.65, 95% CI 0.24–1.8, p=0.41). In patients who achieved CR after induction, the 2-year PFS was 100% for VMPT and 79% for VMP (p=0.02). The 3-year overall survival (OS) was 89.5% in the VMPT group and 88.7% in the VMP group (HR=1.02, 95% CI 0.43–2.46, p=0.96). The incidence of grade 3–4 adverse events (AEs) was similar in both groups. In the VMPT patients and in the VMP patients, the more frequent AEs were neutropenia (36% vs 31%), thrombocytopenia (20% vs 19%), peripheral neuropathy (18% vs 12%), infections (14% vs 10%), and gastrointestinal complications (7% vs 8%), respectively. The weekly infusion of bortezomib significantly decreased the incidence of grade 3–4 peripheral neuropathy (9% for VMPT and 3% for VMP). Conclusion: VMPT is superior to VMP in terms of response rates. Longer follow-up is needed to assess their effects on PFS and OS. The weekly infusion of bortezomib significantly reduced the incidence of grade 3–4 peripheral neuropathy without influencing outcome. Table.

Abstract Abstract 1550 Background: Clofarabine is a second generation nucleoside analogue with activity in adults with AML. A recent randomized phase III study in AML relapse showed higher response rates and better event-free survival with the combination of clofarabine and cytarabine (CA) compared to cytarabine alone. We have also reported the feasibility and safety of the addition of idarubicin to CA (CIA) in a previous phase I and II study. To explore this combination further, we conducted a phase II study of CIA in pts</= 60 years with previously untreated AML. Patients and Methods: Patients (Pts) were eligible if they were </=60 yrs of age with newly diagnosed AML. Pts were excluded for ECOG PS > 2, cardiac ejection fraction < 45%, or active and uncontrolled infection. For the first 30 pts, induction therapy consisted of Clofarabine 22.5 mg/m2 iv daily (days 1–5), Idarubicin 6 mg/m2 daily (days 1–3), and Cytarabine 0.75 g/m2 daily (days 1–5). From pt 31 onward, induction doses were amended to Clofarabine 20 mg/m2 × 5, Idarubicin 10 mg/m2 × 3, and Cytarabine 1 g/m2 × 5. Pts who have not achieved a complete remission following the induction could receive one re-induction course. Pts in CR or CRp continued with up to 6 consolidation cycles with Clofarabine 22.5 mg/m2 × 3, Idarubicin 6 mg/m2 (days 1–2), and Cytarabine 0.75 g/m2 × 3, subsequently amended to Clofarabine 15 mg/m2 × 3, Idarubicin 8 mg/m2 × 2, and Cytarabine 0.75 g/m2 × 3. Supportive care was standard. Pts ≥ 50 yrs were admitted to a laminar air flow room for the duration of the induction. Results: From April 2010 until August 2011, 51 pts have been accrued with a median age of 49 yrs (range 19–59): 33 pts (65%) with de novo AML and 18 pts (35%) with secondary AML (18 related to MDS, 7 related to therapy). Three pts (5%) had a PS of 2. Median WBC at diagnosis was 3.4 × 109/L (0.6-92.3). Thirty-three (65%) pts had abnormal cytogenetics (21/33[64%] poor risk and 5/33 [15%] intermediate risk). Molecular profile: 6 pts (11%) had FLT3/ITD, 3 pts (6%) CEBPA, and 8 pts (16%) NPM1 mutations. Thirty-five pts (69%) achieved CR and 1 (2%) CRp for an overall response rate (ORR) of 71%. 61% pts (31/51) achieved CR following one induction cycle. 18% (9/51) pts required a re-induction and 44% (4/9) of them responded after the re-induction. Responding pts received a median of 2 courses (1–8) courses. With a median follow-up of 23 weeks (3–36+) median remission duration has not been reached with a 1-yr remission probability of 85%. Ten pts (19%) died on study including 2 (4%) who died < 28 days from treatment start (one from septic shock and multi-organ failure, and one from Steven Johnson syndrome). Median overall survival (OS) for responding pts has not been reached (2–36 weeks). One-yr survival probability is 65%. Sixteen pts (31%) proceeded with an allogenic stem cell transplant in CR1. Most toxicities were </= grade 2 and included rash (41 %), nausea (29%), diarrhea (23%), elevated transaminases (21%), and elevated bilirubin (17%). Toxicities > grade 2 included elevated bilirubin (4%), hypokalemia (4%), cellulitis (4%) and seizure (1%). Myelosuppression was ubiquitous but prolonged myelosuppression > 42 days was infrequent. 76 % (39/51) pts had neutropenic fever. Conclusion: Clofarabine, Idarubicin and Cytarabine achieve a response rate of 71% in patients </=60 yrs with previously untreated AML. Induction mortality was low and the toxicity profile was expected and manageable. Longer follow up and comparisons with standard induction therapy will be needed to further assess the role of this combination in AML therapy.

Abstract Background High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) improves survival in multiple myeloma (MM). The introduction of novel agents challenged the role of ASCT at diagnosis. We conducted a multicenter 2X2 randomized trial comparing conventional chemotherapy plus lenalidomide with ASCT followed by maintenance with lenalidomide-prednisone (RP) or lenalidomide (R) alone in newly diagnosed young MM (NDMM) patients. Methods Eligible patients with NDMM ≤ 65 years were enrolled. All patients received Rd induction (four 28-day cycles of lenalidomide 25 mg day 1–21 and low-dose dexamethasone 40 mg day 1,8,15,22) followed by stem cell mobilization. Patients were randomized to receive consolidation with CRD [six 28-day cycles of cyclophosphamide (300 mg/m2 day 1,8,15), dexamethasone (40 mg days 1,8,15,22) and lenalidomide (25 mg days 1–21)] or MEL200-ASCT (melphalan 200 mg/m2 with stem-cell support). Patients were randomly assigned to receive subsequent maintenance with RP (28-day cycles of lenalidomide 25 mg days 1–21 plus prednisone 50 mg every other day) or R alone (28-day cycles of lenalidomide 25 mg days 1–21). Primary study endpoint was progression-free survival (PFS); secondary endpoints included safety, responses and overall survival (OS). Data cut off was May 30th, 2013. Results Three-hundred and eighty-nine patients were enrolled in the trial. Patient characteristics were well balanced between CRD (n=194) and MEL200-ASCT (n=195), and between R (n=195) and RP (n=194) arms. Median follow-up was 31 months. In the intent to treat (ITT) analysis, the median PFS was not reached with MEL200-ASCT and 28 months with CRD (the respective 3-year PFS was 60% vs. 38%, HR=0.62, 95%CI: 0.49-0.85, P=0.003). Median time from enrolment to maintenance was 14 months. In the population of patients eligible for maintenance, 2-year PFS from the start of maintenance was 73% for RP and 56% for R patients (HR= 0.57, 95%CI: 0.34-0.93; P=0.03). In the subgroup of patients who received MEL200-ASCT, 2-year PFS from the start of maintenance was 83% for patients who received RP and 64% for those who received R alone (HR=0.36 95%CI: 0.15-0.87, P=0.02). In the subgroup of patients who received CRD, 2-year PFS from the start of maintenance was 64% for patients who received RP and 47% for those who received R alone (HR=0.75, 95%CI: 0.40-1.39, P=0.36). At present, no differences in OS were noticed between patients randomised to received CRD or MEL200-ASCT, and between patients who received RP or R maintenance. As expected, the rates of grade 3-4 hematologic (85% vs. 26%, P<0.001) and non-hematologic (35% vs. 19%, P=0.003) adverse events (AEs) were higher in the MEL200-ASCT arm compared with the CRD arm. The main non-hematologic AEs were infections (18% vs. 5%, P=0.001) and gastrointestinal AEs (18% vs. 3%, P<0.001). Rates of grade 3-4 hematologic (8% vs. 7%, P=0.85) and non-hematologic (12% vs. 13%, P=0.88). AEs were similar in the RP and R arms. The main non-hematologic AEs in both RP and R groups were infections (3% vs. 3%). At present, 6 second primary malignancies and 3 cases of cutaneous basalioma have been reported. Conclusions MEL200-ASCT significantly prolonged PFS in comparison with CRD. At present no difference in OS was reported, this may be due to the low number of events and to the length of follow-up. The increase in toxicity with MEL200-ASCT did not adversely impact on efficacy. The addition of prednisone to lenalidomide maintenance significantly reduced the risk of progression in comparison with lenalidomide alone, without increasing the toxicity. Updated data with longer follow-up will be presented at the meeting.

5125 Background: The intermittent monotherapy vs continuous combined androgen deprivation using an LHRH analogue and ciproterone acetate and associated components of quality of life. Methods: 854 patients (aged 44–81, mean 72) have been randomised (419 to Continuous and 435 to Intermittent). 350 patients have been randomised in the last years and the study is close to the target sample size 900 patients. The median PSA at randomisation is 1.0 ng/ml ranging from 0.1 to 4. 48 % of patients have a PSA less than 1 ng/ml at randomisation. Results: 1,000 men with a median PSA of 15.9ng/ml were registered between October 1999 and October 2006. 24% of registered patients have a PSA less than 10ng/ml; 39.3% of registered patients have a PSA greater than 20 ng/ml. 90.1% have a T3 tumour and only 13.5% have metastatic prostate cancer. After randomisation, sexual activity increases in the intermittent group to 32% (6 months), 32% (12 months), 24% (24 months) while in the Continuous arm the corresponding percentages are 19%, 20%, 6%, respectively. Among the 435 Intermittent patients only 18% returned to therapy within one year of randomisation because of symptoms or an increase in PSA and 40% have yet to return to therapy within 4 years of randomisation. An estimated 82% (95% Confidence Interval 79%, 87%) of patients have remained free of therapy for at least one year and 60% (95% CI 53%, 68%) for at least 2 years. Patients whose PSA reduces to less than 1 ng/ml at randomisation are off therapy longer than those whose PSA is between 1 and 4 ng/ml (p<0.05). 80% of patients with PSA < 1 ng are off therapy for at least 1.5 years whereas 80% with PSA between 1 and 4 ng/ml are off therapy for at least 9 months. 60% of patients with PSA < 1 ng/ml are off therapy for 2.5 years while 60 % of patients with PSA 1–4 ng/ml are off therapy for 1.5 years. Among the 142 Intermittent patients who returned to therapy because of an increase in PSA or symptoms the median time on therapy was 16.7 weeks (95% CI 15.0, 22.1). The time on therapy did not depend upon PSA at randomisation, p=0.17. The median follow up period is 2.8 years. Conclusions: The early results from this trial are promising and are in line with previous studies of intermittent therapy. It is too early for any progression data.
