Resectable Esophageal Cancer

4530 Background: The aim of this study was to compare survival in a randomized phase III trial of chemoradiotherapy (CHRT) versus surgery alone for localized resectable oesophageal cancer. Methods: Between 2000 and 2004, 91 patients with oesophageal cancer were enrolled in a Scandinavian multicenter study. Patients with resectable oesophageal squamous cell carcinoma (50%) or adenocarcinoma (50%) were randomized to chemoradiotherapy (CHRT) or surgery alone. Chemotherapy (CHT) was given in 3 cycles with cisplatin 100 mg/m2, day 1 and 5-fluorouracil 750 mg/m2/24 hours, infusion day 1–5, every three weeks. After one induction chemotherapy course, radiotherapy including the primary tumour and defined locoregional lymph nodes, was given concomitant with the following CHT cycles, to a total dose of 64 Gy, in 32 fractions. Surgery was performed according to Ivor Lewis and lymph nodes resected with standard two-field technique. Results: At a median follow-up of 51.8 month’s 65 deaths are noted. In the chemoradiation group 50% of the patients accomplished therapy according to protocol, 40% were treated with modifications of the protocol and radical resection was performed 76% of the patients. Median survival was 12.8 months for chemoradiation and 15.8 months for the surgery group. There was no significant difference in 1-year survival 56% and 55% for CHRT and surgery, respectively. By two years, survival curves diverge and 2-years survival was 37% (CI 95%: 23–51%) for the CHRT group and 25% (CI 95%: 12–39%) for the surgery group. At four years, survival was 29% for CHRT versus 23% for surgery (CI 95% CHRT: 16–43%, CI 95% Surgery: 10–36%). Both treatments were well tolerated and no treatment related deaths were recorded in any of the treatment arms. Most deaths were due to tumor disease (66%) in both groups. Conclusions: No statistically significant differences between the treatment arms were seen and survival results are equal to earlier reported. Both treatment arms were well tolerated. No significant financial relationships to disclose.

Esophagectomy For Cancer

Over the past decades, survival rates for patients with resectable esophageal cancer have improved significantly. Consequently, the sequelae of having a gastric conduit, such as development of micronutrient deficiencies, become increasingly apparent. This study investigated postoperative micronutrient trends in the follow-up of patients following a minimally invasive esophagectomy (MIE) for cancer. Patients were included if they had at least one postoperative evaluation of iron, ferritin, vitamins B1, B6, B12, D, folate or methylmalonic acid. Data were available in 83 of 95 patients. Of these, 78.3% (65/83) had at least one and 37.3% (31/83) had more than one micronutrient deficiency at a median of 6.1 months (interquartile range (IQR) 5.4–7.5) of follow-up. Similar to the results found in previous studies, most common deficiencies identified were: iron, vitamin B12 and vitamin D. In addition, folate deficiency and anemia were detected in a substantial amount of patients in this cohort. At 24.8 months (IQR 19.4–33.1) of follow-up, micronutrient deficiencies were still common, however, most deficiencies normalized following supplementation on indication. In conclusion, patients undergoing a MIE are at risk of developing micronutrient deficiencies as early as 6 up to 24 months after surgery and should therefore be routinely checked and supplemented when needed.

Abstract High-dose chemotherapy (HDT) improves the outcome of patients with multiple myeloma (MM) in comparison to conventional chemotherapy. Dose-escalating strategies including tandem HDT are currently evaluated to further improve remission rates and survival of patients. Therefore we conducted a randomized multicenter trial to compare an intensified conditioning regimen with the current standard high-dose melphalan. The primary study endpoint was response rate, with overall survival (OS), event-free survival (EFS) and toxicity analysed as secondary endpoints. Between 1997 and 1999 a total of 56 patients with stage II and III disease, who were matched for age (median 56 years), number of previous therapies (median time from diagnosis to transplant 7 months) and different risk factors (beta2-microglobulin, LDH, CRP, cytogentic abnormalities, chemoresistant disease, IgA-subtype, renal impairment), were randomized. All patients received 2 courses of oral idarubicine/dexamethasone and 2 courses of intravenous cyclophosphamide/adriamycine in combination with G-CSF followed by peripheral stem cell collection. Thirty patients were treated with melphalan 200mg/m2 (HD-M) whereas 26 patients received idarubicine 42mg/m2, melphalan 200mg/m2 and cyclophosphamide 120mg/kg (HD-IMC) followed by autologous blood stem cell transplantation. Acute toxicity was higher with HD-IMC, including 5 (20%) treatment-related deaths due to infections versus none (0%) in the HD-M group. This lead to early termination of the study. Severity of mucositis (grade III-IV 19 vs. 8 pts., p=0.001), CRP (20 vs. 7 mg/dl, p<0.001), days of fever (11 vs. 3, p<0.001), days with iv-antibiotics (13 vs. 4, p<0.001), number of erythrocyte-transfusions (6 vs. 2, p<0.001), number of platelet-transfusions (16 vs. 4, p<0.001) and days to granulocyte engraftment (18 vs. 11, p=0.007) were significantly higher after HD-IMC. After a follow-up of 5 years analysis restricted to patients surviving the first 30 days after HDT showed a trend to higher response rates (CR+vgPR: 47% (95%CI 24–72%) vs. 35% (95%CI 18–56%), PR 37% (95%CI 17–63%) vs. 48% (95%CI 29–68%) and time-to-progression (median 31 vs. 15 months, p=0.1) in the HD-IMC treatment arm in comparison to HD-M, but there was no significant difference in EFS and OS (median 22 vs. 30, p= 0.31 and 66 vs. 66 months, p=0.8, respectively). Univariate analysis demonstrated that LDH levels > 200 U/L (p=0.04) and chemoresistant disease (p=0.05) were a bad prognostic factor for EFS. Beta2-Microglobulin levels > 5mg/dl (p=0.01), abnormal conventional cytogenetics (p=0.02) and LDH levels > 200 U/L (p=0.03) were predictive for an inferior OS. In conclusion intensified conditioning for HDT had an intolerable high treatment-related mortality and did not improve EFS and OS in patients with multiple myeloma.

Abstract Background: THAL, whose activity in MM was discovered in the setting of advanced and refractory disease in the late 1990’s (Singhal, NEJM, 2000), has become the standard front-line therapy in combination with dexamethasone (DEX). In a randomized phase III tandem transplant trial, TT2, a higher complete response (CR) rate and longer event-free survival (EFS) had been observed on the THAL arm (Barlogie, NEJM, 2006). The similar overall survival (OS) on THAL and control arms had been attributed to the routine use of THAL as salvage therapy for the patients randomized to the No-THAL arm and the shorter post-relapse OS among patients randomized to the THAL arm. Patients and Methods: With a median follow-up on TT2 of 53mo, 107 patients have relapsed and 219 died. Subset analyses were performed to determine whether THAL confers an OS advantage in any subgroup of patients. Results: 6-yr EFS and OS rates are 48%/63% on THAL and 38%/58% on control arm (p=0.01/0.67). Post-relapse OS is now similar with median durations of 5.3mo/4.3mo among control/THAL arms (p=0.11). According to multivariate analyses of 11 standard prognostic factors, EFS was shorter among patients treated without THAL, in the presence of cytogenetic abnormalities (CA), B2M and LDH elevations and low albumin, whereas CR was favorable; OS was inferior with CA, high LDH, low albumin and in patients not receiving 2nd transplant or not achieving CR. Randomization to THAL was beneficial only in the >2 risk factor group: 6-yr OS was 47% in 31 patients on THAL and 12% in 31 control patients (Figure 1, p=0.01). When examined in the context of GEP (70 gene model-based high versus low risk groups) and inter-phase FISH data (amp1q21), available in 260 patients, the 57 with GEP low risk and absence of amp1q21 receiving THAL had 5-yr OS of 90% compared to 74% among 73 controls (p=0.13). Conclusion: With longer follow-up of 53mo on TT2, EFS remains superior among patients randomized to THAL; post-relapse survival is no longer inferior among those randomized to THAL; THAL benefited a high-risk subgroup with >2 standard risk factors, whereas no significant `difference has yet emerged among genetically defined subgroups.

Abstract From 11/01 until 04/05, 832 patients (median age 46, 18–60) with AML (previous diagnosis of myelodysplasia or myeloproliferative disorder, and M3 excluded) were included in prospective phase III AML 2001 trial. After achieving CR, research to identify an HLA-identical sibling was performed for all patients as they received low dose consolidation (Daunorubicin (D): 60 mg/m2 × 2d OR Idarubicin (I): 12 mg/m2 × 2d plus SC ARAC 100 mg/m2 ×7d). 33 % patients had a donor then could proceed to a T-replete alloSCT: either conventional if age ≤ 50 (bone marrow graft; conditioning regimen: TBI (12 Gy 6 fractions over 3d) - cyclophosphamide (60 mg/kg × 2d); GvHD prophylaxis: ciclosporin-methotrexate d1+3+6) = arm M; or NST if age 51–60 (peripheral blood; Busulfan (oral Bu 4–8 mg/kg over 2d) - Fludarabin (30 mg/m2 × 4d) – Thymoglobulin® (2,5 mg/kg × 2d); ciclosporin alone), AFTER intensive consolidation (D: 60 mg/m2 × 2d OR I: 12 mg/m2 × 2d plus ARAC 3 g/m2 × 8 doses over 4d) = arm m. A small group of patients with a donor but low-risk prognostic features (favorable cytogenetics, no hyperleucocytosis, CR after 1 induction = 3% CR1 patients) didn’t receive 1st line alloSCT but intensive consolidation then a 2nd HD ARAC course; alloSCT was therefore considered at relapse = arm C. Patients without donor proceed to intensive consolidation then 1 or 2 autoSCT (1st after HDM 200 mg/m2 according to randomization, then Bu 16 mg/kg over 4d + HDM 140 mg/m2 for all patients) = arms A + B; they were combined for analysis as no difference was observed for DFS and OS. Actual results concern 532 patients with 15 months follow-up (A + B = 367; M = 111; m = 54). Median age was different between 3 groups (A + B = 46; M = 40; m = 54) as no difference was observed regarding leukocytosis or cytogenetic subgroups: favorable (t8;21) or inv16: A + B = 15%; M = 11%; m = 11%), intermediate (A + B = 72%; M = 78%; m = 67%), defavorable (5, 7, complex, 11q23 except t(9;11) or 3q; A + B = 13%; M = 11%; m = 22%). Conventional alloSCT results in better 2y DFS than autoSCT arms (M 71% vs A+B 52%, p=0,007) thought 2y OS advantage remains non significant (M 77% vs A+B 68%, p=0,06) as toxic death rate is higher (36% all deaths in arm M vs 14 % in arms A + B). No significant difference was observed between conventional alloSCT and NST (2y DFS 62%, OS 68%). Advantage for NST over autoSCT arms was non significant for DFS (p=0,24) and OS. Same results are obtained if considering only patients aged > 50: 2y EFS (m 62% vs A+B 50%, p=0,27) and OS (m 68% vs A+B 65%). After NST, toxicity accounts for 25% deaths, as relapse rate is 40% at 2y with no late relapse thereafter (vs 48 % at 2y and 61 % at 4y in arms A + B). In conclusion: 1) conventional alloSCT remains the best consolidation treatment for patients ≤ 50 with AML in CR1 despite higher toxicity; 2) NST after intensive consolidation seems promising: for older patients as toxicity is lower than conventional alloSCT, as few late relapse are observed in comparison with chemotherapy or autoSCT approaches; 3) NST may extend use of alternative sources of allogeneic hematopoietic stem cells to propose alloSCT approach for the majority of patients ≤ 60 with AML in CR1. Data with more than 2 years follow-up will be presented.

523 Background: Adjuvant trastuzumab (Herceptin [H]) with chemotherapy improves outcome in HER2+ breast cancer (BC). Preclinical studies suggest H may enhance RT. We herein assess if H given with adjuvant RT increases adverse events (AE) after breast conserving surgery or mastectomy. Methods: N9831 randomized 3505 women with pT1–3N1–2M0, pT2–3N0M0, or pT1cN0M0 (ER/PR negative) HER2+ BC to doxorubicin (A) and cyclophosphamide (C) followed by weekly paclitaxel (T), AC→T→H, or AC→TH→H. Post-lumpectomy breast ± nodal RT was recommended, as was post-mastectomy chest wall + nodal RT (>3 nodes +); internal mammary RT was prohibited. RT started within 5 weeks of completion of T and allowed concurrently with H. 2324 eligible patients were enrolled on study prior to April 25, 2004: 1460 patients receiving RT are available for analysis of RT-associated AEs. Also, 1286 patients on +H arms who completed T (908 +RT and 378 -RT) are available for analysis of clinical cardiac events (CE). Rates of RT-associated AEs were compared across treatment arms, and rates of CE were compared for +RT vs -RT patients within +H arms. All reported p-values are for chi-squared statistics. Results: With a median follow-up of 1.5 years, significant differences among arms in RT-associated AEs were not identified. No significant differences across arms in +RT patients existed in the incidence of skin reaction (p=0.78), pneumonitis (p=0.78), dyspnea (p=0.87), cough (p=0.54), esophageal dysphagia (p=0.26), or neutropenia (p=0.16). There was a significant difference in +RT patients in the incidence of leukopenia (p=0.02) with higher incidence rates in the arms receiving H. RT did not increase the frequency of CE. In the AC→T→H arm, the incidence of CE was 2.2% in +RT patients versus 2.9% in -RT patients. In the AC→TH→H arm, the incidence of CE was 1.5% in +RT patients versus 6.3% in -RT patients. No difference in CE was seen between left- and right-sided RT fields in +RT patients in either +H arm. Conclusion: Concurrent administration of adjuvant RT with H in early stage breast cancer patients is not associated with an increased incidence of acute RT AEs. Further follow-up is required to assess late AEs. No significant financial relationships to disclose.

516 Background: Evidence suggests that docetaxel is more effective than paclitaxel, and paclitaxel is more effective when given weekly than every 3 weeks in metastatic breast cancer (BC). Methods: Eligibility included axillary lymph node positive or high-risk (tumor at least 2 cm) node-negative BC. All patients received 4 cycles of AC (doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2) every 3 weeks, followed by either: (1) paclitaxel 175 mg/m2 every 3 weeks × 4 (P3), (2) paclitaxel 80 mg/m2 weekly × 12 (P1), (3) docetaxel 100 mg/m2 every 3 weeks × 4 (D3), or (4) docetaxel 35 mg/m2 weekly × 12 (D1). The primary comparisons included taxane (P vs. D) and schedule (every 3 weeks vs. weekly), and secondary comparisons included P3 vs. other arms. The trial had 86% power to detect a 17.5% decrease in disease-free survival (DFS) for either primary comparison, and 80% power to detect a 22% decrease for the secondary comparisons (2-sided nomimal 5% level tests corrected for multiple comparisons). Results: A total of 4,950 eligible patients were accrued. There was no difference in the primary comparisons afer 856 DFS events and 483 deaths after a median follow-up of 46.5 months at the 4th interim analysis ( www.sabcs.org , abstract 48). This is the final pre-specified analysis for the primary comparisons after 1,042 DFS events and 650 deaths (with 1,020 DFS events at this time, to be updated at the meeting). After a median followup of 60.2 months, there remains no significant difference in the hazard ratio (HR) for the taxane (1.02; p=0.73) or schedule (1.07; p=0.30) (as in the first analysis). In secondary comparisons of the standard arm (P3) with the other arms (HR > 1 favoring the experimental arms), the HRs were 1.30 (p = 0.003) for arm P1, 1.24 (p=0.02) for arm D3, and 1.09 (p=0.33) for arm D1. Analysis of interaction by hormone-receptor status will be presented. The incidence of worst grade toxicity (grade 3/4) was 24%/6% for arm P3, 24%/3% for arm P1, 21%/50% for arm D3, and 38%/6% for arm D1. Conclusions: There were no differences in DFS when comparing taxane or schedule overall. DFS was significantly improved in the weekly paclitaxel and every 3-week docetaxel arms compared with the every 3-week paclitaxel arm. [Table: see text]

1000 Background: NSABP B-32, the largest surgical prospective randomized phase III trial was designed to compare overall survival (OS), disease-free survival (DFS), and morbidity between SNR alone vs SNR + AD in SN negative (-) pts. We present 10 yr outcome data for primary endpoints as well as updated data on the effect of occult metastases, found later in the SN by central, detailed pathologic analysis. Methods: 5,611 women with operable, clinically N0, invasive breast cancer were randomized to SNR + AD (Group [Grp] 1) or to SNR alone with AD only if SNs were positive (Grp2). 3,989 (71.1%) of 5,611 pts were SN-. 3,986 (99.9%) of these SN- pts had follow-up information: Grp 1: 1,975, Grp 2:2,011. Median time on study was 9.4 yrs. Cox proportional hazard models adjusting for study stratification variables were used to compare OS and DFS between the two groups. Two-sided p values were used. HR values > 1 indicate a more favorable outcome in Grp 1 Results: At 10 yrs, there continues to be no significant difference in OS between the two groups (HR: 1.11, p = 0.27). 10 yr Kaplan-Meier (K-M) estimates for OS are 87.8% for SNR alone and 88.9% for SNR + AD. There continues to be no significant difference in DFS between the two groups (HR: 1.01, p=0.92). 10-yr K-M estimates for DFS were 76.9% for both groups. Occult nodal disease was originally detected in 3,884 pts (15.8%) with SN- on initial H and E analysis. Comparisons between the groups with and without occult disease yielded an adjusted HR for OS: 1.25 (p = 0.08) with an absolute difference at 10 yrs of 2.8% and a HR for DFS: 1.24 (p = 0.018) with an absolute difference of 4.1%. The cumulative incidences of local-regional events were low (10-yr values: SNR 4.0%, SNR+AD, 4.3%) and not significant (HR: 0.95, p = 0.77). Conclusions: At 10 yrs there continues to be no significant differences in OS and DFS between SNR and SNR + AD in pts with negative SN. The relative increase in risk of DFS and OS for pts with occult SN metastases remains stable.

462 Background: Due to the lack of prospective randomized phase III trial data, we have analysed patients with ACC treated between 2000 and 2011. Methods: All the patients given Mitotane (standard treatment of ACC in UHB, Birmingham) where extracted from pharmacy database. Results: 23 patients were identified, age 26-74 (median 53). Follow-up for whole group was 14–167m, median 60. Overall survival (OS) was 3-48m, medium 11.1 patient with slowly growing disease is still alive (167m) with 2nd dg of breast cancer. 19 patients were treated for metastatic disease, 4 in adjuvant setting. 7 patients were managed by endocrinologist only (3 adjuvant, 2 poor PS, 1 reluctant to treatment and 1 details unknown). 16 patients were under shared care. 4 these patients were never exposed to chemotherapy (2 poor PS, 1 returned to Africa, died within 5 months, 1 declined chemotherapy, still alive at 16 months post). 6/19 metastatic patients had chemotherapy as 1st treatment (4 patients etoposide/doxorubicin/cisplatin chemotherapy, 1 etoposide/carboplatin, 1 etoposide/cisplatin), 7 were treated with chemotherapy on PD(6 streptozocin, 1 etoposide/doxorubicin/cisplatin, 1 etoposide/cisplatin). There was no significant difference in OS when those approaches were compared (1st group 7-16 m, median 10, 2nd group 3-14, median 11) But TTP has been slightly worse for treatment on PD as expected (1st group 3-13m, median 6.5; 2nd group 3-14, median 3), although might be due to tendency to use Streptozocin, consistant with preliminary published results of FIRMACT trial.3 patients were treated with 2 lines of chemotherapy (age 30,31, 38), TTP 2- 5 m. Adjuvant patients within our sample has been followed up for limited perion only (11 – 71m, median 22.5), however no recurrence was diagnosed so far.In metastatic patient population 4 patients were treated for recurrence with time to relapse 3-43m, medium 23.5. Conclusions: ACC is heterogenic disease as confirmed by our survival data. In unselected population median OS is comparable to FIRMACT. Consistant with literature review, chemotherapy threatment can be delivered as 1st-line or delayed till PD. 2nd-line chemotherapy is of limited efficacy.

2 Background: We aimed to explore the dose response relationship for two 3 Gray (Gy) hypofractionated radiotherapy (hRT) schedules for localised prostate cancer (PCa). Methods: hRT schedules of 60Gy/20 fractions (f) and 57Gy/19f were compared with conventional RT (cRT) 74Gy/37f; iso-effective for alpha-beta ratios of 2.5Gy and 1.5Gy respectively. The trial was powered to demonstrate non-inferiority between each hRT schedule and cRT, with 3,213 patients (pt) needed to rule out 5% inferiority (80% power, 1-sided alpha 5%) assuming 70% event-free rate in cRT, corresponding to a critical hazard ratio (HR) of 1.21. The trial was not formally powered to directly compare the two hRT schedules. Pt with N0 T1b-T3a localised PCa were randomized (1:1:1 ratio). The primary endpoint was PCa progression (freedom from biochemical failure by Phoenix consensus guidelines or PCa recurrence). Acute toxicity was assessed up to 18 weeks post treatment and late side effects to 5 years (yr) by RTOG, LENT-SOM and patient reported outcomes (PROs). Results: 3,216 pts were randomized between 2002 and 2011; 1,065 (74Gy), 1,074 (60Gy), 1,077 (57Gy). Baseline characteristics were well balanced across groups: median age 69 yr; NCCN risk group 15% low, 73% intermediate, 12% high. With median follow up 5.2yr, 5yr progression-free rate (95% CI) was 74Gy: 88.3% (86.0%, 90.2%); 60Gy: 90.6% (88.5%, 92.3%), 57Gy: 85.9 (83.4, 88.0); HR60/74: 0.83, 90% CI (0.68, 1.03), HR57/74: 1.20, 90% CI (0.99, 1.45). Significantly more events were observed with 57Gy compared to 60Gy; HR57/60: 1.44, 90% CI (1.18, 1.75), log-rank p=0.003. No significant difference in acute RTOG bladder or bowel toxicity was observed between hRT schedules. Late toxicity profile was favorable; with grade 2+ RTOG bladder (60Gy: 16/960 (1.7%); 57Gy: 11/962 (1.1%), p=0.34) and bowel (60Gy: 28/960 (2.9%); 57Gy: 17/962 (1.8%), p=0.10) toxicity at 2yr. Analysis of LENT-SOM and PROs supported these results. Conclusions: With 5 yr follow-up treatment with a 3Gy schedule of 60Gy/20f shows improved treatment efficacy compared to 57Gy/19f and is non-inferior to 74Gy/37f with a similar low level of acute and late normal tissue damage.

The Difference

580 Background: SB3 is an approved biosimilar of reference trastuzumab (TRZ). At additional 2-year follow-up after completing neoadjuvant and adjuvant treatment, there was a difference in event-free survival (EFS), but no difference in overall survival (OS) between SB3 and TRZ. Upon monitoring quality attributes of TRZ, a marked downward shift in antibody-dependent cell-mediated cytotoxicity activities (ADCC) was observed in TRZ lots with expiry dates from Aug 2018 to Dec 2019. Some of the lots were used in the Phase III study. This is a post-hoc analysis of EFS and OS by ADCC status from a 3-year follow-up to investigate the difference in EFS between SB3 and TRZ. Methods: After completion of neoadjuvant and adjuvant therapy in patients with HER2 positive early breast cancer, patients from selected countries participated in a 5-year follow-up study (NCT02771795). Within the TRZ group, patients exposed to at least one shifted ADCC lot and those never exposed to shifted ADCC lot during neoadjuvant period were considered as “Exposed” and “Unexposed,” respectively. EFS and OS after 3-year follow-up was analyzed by ADCC status in the long-term follow-up set. Results: 367 patients (SB3, N = 186; TRZ, N = 181) were enrolled in the follow-up study. Within TRZ, 55 patients were Unexposed and 126 patients were Exposed. At a median follow-up duration of 40.8 months in SB3 and 40.5 months in TRZ, 3-year EFS rates were 92.5% in SB3, 94.5% in Unexposed, and 82.5% in Exposed and OS rates were 97.0%, 100%, and 90.6%, respectively. Exposed was associated with decreased EFS compared to Unexposed (HR 0.14, 95% CI 0.04-0.51, p= 0.003). There was a trend of decreased OS in Exposed compared to Unexposed, however, there was no significant difference (HR 0.14, 95% CI 0.02-1.15, p= 0.068). Between SB3 and Unexposed, no difference was observed in EFS (HR 1.06, 95% CI 0.33-3.44, p= 0.923), or OS (HR 0.54, 95% CI 0.05-5.44, p= 0.600). Conclusions: Within the TRZ group, Exposed showed significantly lower EFS compared to Unexposed, and a similar trend was observed in OS with no statistical significance. Between SB3 and Unexposed, no significant difference in EFS or OS was observed. Clinical trial information: NCT02771795.
