Background: Previous findings showed that cediranib-olaparib increased PFS in women with recurrent platinum-sensitive ovarian cancer compared to olaparib alone. Methods: BAROCCO trial randomized 123 patients: 80 mg/m2 paclitaxel weekly up to 24 weeks (control), olaparib 300 mg tablets twice daily together with 20 mg cediranib daily (continuous schedule) or with 20 mg cediranib 5 days/week (intermittent schedule) until progression. The primary objective was the PFS comparison between each experimental arm and the control (alpha one-sided 5%; power 80%; HR 0.5). Results: The median platinum-free interval was 1.9 months, 60% of patients had been pretreated with 3 or more chemotherapy lines. Median PFS for paclitaxel, the continuous, and the intermittent schedules were 3.1, 5.6, and 3.8 months. The HR for PFS in the continuous arm vs control was 0.76 (90% CI: 0.50–1.14, p = 0.265). The HR for PFS in the intermittent arm vs control was 1.03 (90% CI: 0.68–1.55, p = 0.904). Treatment was discontinued due to adverse events in 15%, 20%, and 5% of patients in the control, continuous and intermittent arms. Grade ≥ 3 anemia and diarrhea and hypertension of any grade occurred only in the experimental arms, and peripheral neuropathies and alopecia only in the control arm. Five serious adverse drug reactions occurred and two were fatal: one in the control and one in the continuous arm. Conclusions: The combination of cediranib-olaparib was not superior to chemotherapy in terms of PFS in heavily pretreated platinum-resistant ovarian cancer patients. However, this oral doublet, is active and may offer a non-chemotherapy option in this difficult to treat population.

BACKGROUND: This trial investigated the hypothesis that the treatment with trabectedin/PLD (TP) to extend the platinum-free interval (TFIp) can improve overall survival (OS) in patients with recurrent ovarian cancer (OC). METHODS: Patients with OC (up to two previous platinum-based lines), with a TFIp of 6-12 months, were randomised to receive carboplatin/PLD (CP) or TP followed by platinum therapy at relapse. The primary endpoint was OS (HR: 0.75). RESULTS: The study enrolled 617 patients. The median TFIp was 8.3 months and 30.3% of patients had received two previous platinum lines. 74% and 73.9% of patients, respectively, received a subsequent therapy (ST) in the CP and TP arm; in the latter TP arm 87.2% of ST was platinum-based, as per protocol. The median OS was 21.4 for CP and 21.9 months for TP (HR 1.13; 95% CI: 0.94-1.35; p = 0.197). Grade 3-5 adverse reactions occurred in 37.1% of patients in the CP arm and 69.7% of patients in the TP arm, and the most frequent were neutropenia (22.8% CP, 39.5% TP), gastrointestinal (7.1% CP, 17.4% TP), hepatic (0.7% CP, 19.1% TP). CONCLUSIONS: This study did not meet the primary endpoint. CP combination remains the standard for patients with recurrent OC and a 6-12 months TFIp; TP is an effective treatment in patients suffering from persistent platinum toxicities.

Background: The PORTEC-3 trial investigated the benefit of combined adjuvant chemotherapy and radiotherapy versus pelvic radiotherapy alone for women with high-risk endometrial cancer. We updated the analysis to investigate patterns of recurrence and did a post-hoc survival analysis. Methods: In the multicentre randomised phase 3 PORTEC-3 trial, women with high-risk endometrial cancer were eligible if they had International Federation of Gynaecology and Obstetrics (FIGO) 2009 stage I, endometrioid grade 3 cancer with deep myometrial invasion or lymphovascular space invasion, or both; stage II or III disease; or stage I–III disease with serous or clear cell histology; were aged 18 years and older; and had a WHO performance status of 0–2. Participants were randomly assigned (1:1) to receive radiotherapy alone (48·6 Gy in 1·8 Gy fractions given on 5 days per week) or chemoradiotherapy (two cycles of cisplatin 50 mg/m2 given intravenously during radiotherapy, followed by four cycles of carboplatin AUC5 and paclitaxel 175 mg/m2 given intravenously), by use of a biased coin minimisation procedure with stratification for participating centre, lymphadenectomy, stage, and histological type. The co-primary endpoints were overall survival and failure-free survival. Secondary endpoints of vaginal, pelvic, and distant recurrence were analysed according to the first site of recurrence. Survival endpoints were analysed by intention-to-treat, and adjusted for stratification factors. Competing risk methods were used for failure-free survival and recurrence. We did a post-hoc analysis to analyse patterns of recurrence with 1 additional year of follow-up. The study was closed on Dec 20, 2013; follow-up is ongoing. This study is registered with ISRCTN, number ISRCTN14387080, and ClinicalTrials.gov, number NCT00411138. Findings: Between Nov 23, 2006, and Dec 20, 2013, 686 women were enrolled, of whom 660 were eligible and evaluable (330 in the chemoradiotherapy group, and 330 in the rad

Contains fulltext : 232064.pdf (Publisher’s version ) (Open Access), PURPOSE: The survival results of the PORTEC-3 trial showed a significant improvement in both overall and failure-free survival with chemoradiation therapy versus pelvic radiation therapy alone. The present analysis was performed to compare long-term adverse events (AE) and health-related quality of life (HRQOL). METHODS AND MATERIALS: In the study, 660 women with high-risk endometrial cancer were randomly assigned to receive chemoradiation therapy (2 concurrent cycles of cisplatin followed by 4 cycles of carboplatin/paclitaxel) or radiation therapy alone. Toxicity was graded using Common Terminology Criteria for Adverse Events, version 3.0. HRQOL was measured using EORTC QLQ-C30 and CX24/OV28 subscales and compared with normative data. An as-treated analysis was performed. RESULTS: Median follow-up was 74.6 months; 574 (87%) patients were evaluable for HRQOL. At 5 years, grade ≥2 AE were scored for 78 (38%) patients who had received chemoradiation therapy versus 46 (24%) who had received radiation therapy alone (P = .008). Grade 3 AE did not differ significantly between the groups (8% vs 5%, P = .18) at 5 years, and only one new late grade 4 toxicity had been reported. At 3 and 5 years, sensory neuropathy toxicity grade ≥2 persisted after chemoradiation therapy in 6% (vs 0% after radiation therapy, P < .001) and more patients reported significant tingling or numbness at HRQOL (27% vs 8%, P < .001 at 3 years; 24% vs 9%, P = .002 at 5 years). Up to 3 years, more patients who had chemoradiation therapy reported limb weakness (21% vs 5%, P < .001) and lower physical (79 vs 87, P < .001) and role functioning (78 vs 88, P < .001) scores. Both treatment groups reported similar long-term global health/quality of life scores, which were better than those of the normative population. CONCLUSIONS: This study shows a long-lasting, clinically relevant, negative impact of chemoradiation therapy on toxicity and HRQOL, most importantly persistent peripheral sensory neuropathy. Phys

Background: The survival results of the PORTEC-3 trial showed a significant improvement in both overall and failure-free survival with chemoradiotherapy versus pelvic radiotherapy alone. The present analysis was performed to compare long-term adverse events (AE) and health-related quality of life (HRQOL). Patients and methods: 660 women with high-risk endometrial cancer were randomly assigned to receive chemoradiotherapy (2 concurrent cycles of cisplatin followed by 4 cycles of carboplatin/paclitaxel) or radiotherapy alone. Toxicity was graded using CTCAE v3.0. HRQOL was measured using EORTC QLQ-C30 and CX24/OV28-subscales and compared to normative-data. An as-treated analysis was performed. Results: Median follow up was 74.6 months; 574 (87%) patients were evaluable for HRQOL. At 5 years, grade ≥2 AE were scored for 78 (38%) patients who had received chemoradiotherapy versus 46 (24%) who had received radiotherapy (p=0.008). Grade 3 AE did not differ significantly between the groups (8% vs 5%, p=0.18) at 5 years, and only one new late grade 4 toxicity had been reported. At 3 and 5 years, sensory neuropathy toxicity grade ≥2 persisted after chemoradiotherapy in 6% (vs 0% after radiotherapy, p<0.001) and more patients reported significant tingling or numbness at HRQOL (27% vs 8%, p<0.001 at 3 years; 24% vs 9%, p=0.002 at 5 years). Until 3 years, more patients who had chemoradiotherapy reported limb weakness (21% vs 5%, p<0.001) and lower physical (79 vs 87, p<0.001) and role functioning (78 vs 88, p<0.001) scores. Both treatment groups reported similar long-term global health/QOL scores, which were better than those of the normative-population. Conclusion: This study shows a long-lasting, clinically relevant, negative impact of chemoradiotherapy on toxicity and HRQOL, most importantly persistent peripheral sensory neuropathy. Physical and role functioning impairments were seen until 3 years. These long-term data are essential for patient information and

Background: Although women with endometrial cancer generally have a favourable prognosis, those with high-risk disease features are at increased risk of recurrence. The PORTEC-3 trial was initiated to investigate the benefit of adjuvant chemotherapy during and after radiotherapy (chemoradiotherapy) versus pelvic radiotherapy alone for women with high-risk endometrial cancer. Methods: PORTEC-3 was an open-label, international, randomised, phase 3 trial involving 103 centres in six clinical trials collaborating in the Gynaecological Cancer Intergroup. Eligible women had high-risk endometrial cancer with FIGO 2009 stage I, endometrioid-type grade 3 with deep myometrial invasion or lymph-vascular space invasion (or both), endometrioid-type stage II or III, or stage I to III with serous or clear cell histology. Women were randomly assigned (1:1) to receive radiotherapy alone (48·6 Gy in 1·8 Gy fractions given on 5 days per week) or radiotherapy and chemotherapy (consisting of two cycles of cisplatin 50 mg/m2 given during radiotherapy, followed by four cycles of carboplatin AUC5 and paclitaxel 175 mg/m2) using a biased-coin minimisation procedure with stratification for participating centre, lymphadenectomy, stage of cancer, and histological type. The co-primary endpoints were overall survival and failure-free survival. We used the Kaplan-Meier method, log-rank test, and Cox regression analysis for final analysis by intention to treat and adjusted for stratification factors. The study was closed on Dec 20, 2013, after achieving complete accrual; follow-up is ongoing. PORTEC-3 is registered with ISRCTN, number ISRCTN14387080, and ClinicalTrials.gov, number NCT00411138. Results: 686 women were enrolled between Nov 23, 2006, and Dec 20, 2013. 660 eligible patients were included in the final analysis, of whom 330 were assigned to chemoradiotherapy and 330 were assigned to radiotherapy. Median follow-up was 60·2 months (IQR 48·1–73·1). 5-year overall survival was 81·8% (95% CI

Background: Trabectedin, in addition to its antiproliferative effect, can modify the tumour microenvironment and this could be synergistic with bevacizumab. The efficacy and safety of trabectedin and bevacizumab ± carboplatin have never been investigated. Methods: In this phase 2 study, women progressing between 6 and 12 months since their last platinum-based therapy were randomised to Arm BT: bevacizumab, trabectedin every 21 days, or Arm BT+C: bevacizumab, trabectedin and carboplatin every 28 days, from cycles 1 to 6, then trabectedin and bevacizumab as in Arm BT. Primary endpoints were progression-free survival rate (PFS-6) and severe toxicity rate (ST-6) at 6 months, assuming a PFS-6 ≤35% for BT and ≤40% for BT+C as not of therapeutic interest and, for both arms, a ST-6 ≥ 30% as unacceptable. Results: BT+C (21 patients) did not meet the safety criteria for the second stage (ST-6 45%; 95%CI: 23%–69%) but PFS-6 was 85% (95%CI: 62%–97%). BT (50 patients) had 75% PFS-6 (95%CI: 60%–87%) and 16% ST-6 (95%CI 7%–30%). Conclusions: BT compared favourably with other platinum- and non-platinum-based regimens. The combination with carboplatin needs to be assessed further in a re-modulated safer schedule to confirm its apparent strong activity. Clinical Trial Registration: NCT01735071 (Clinicaltrials.gov)

Background: Patients with recurrent/metastatic uterine leiomyosarcoma (U-LMS) have a dismal prognosis. This phase II study aims to evaluate trabectedin efficacy and safety in advanced U-LMS. Methods: Eligible patients had received ≥ one line of chemotherapy. Gemcitabine ± docetaxel naive patients were randomised to Arm A: trabectedin 1.3 mg/m2 or calibration Arm B: gemcitabine 900 mg/m2 and docetaxel 75 mg/m2. Patients who had already received gemcitabine ± docetaxel directly entered Arm A. Primary end-point: 6-month progression-free rate (PFS-6). The null hypothesis that the true PFS-6 = 14% was tested against a one-sided alternative. This design yielded a 5% type I error rate and 90% power when the true PFS-6 is 25%. Results: Overall, 126 patients entered Arm A (45 from randomisation and 81 directly) and 42 Arm B. Arm A patients characteristics: median age = 57; ≥2 previous chemotherapy lines = 37.4%; metastatic disease = 93%. The study met the condition for trabectedin activity: PFS-6 = 35.2% (95% CI: 26.2–45). No difference in PFS by the number of previous chemotherapy lines emerged. Median OS = 20.6 months (IQR: 8–36.4). In Arm B, the PFS-6 = 51.5% (95% CI: 33.5–69.2). No toxic deaths occurred. In Arm A, only 4 patients interrupted treatment for toxicity. Conclusions: Trabectedin is active and well tolerated, retaining similar efficacy across one to three previous lines of chemotherapy.

BACKGROUND: Five percent to 20% of stage I endometrial cancer patients undergoing total abdominal hysterectomy and bilateral salpingo-oophorectomy develop vaginal and pelvic recurrences. Adjuvant radiotherapy can improve locoregional control but not survival. This randomized trial aimed to determine whether a modified radical (Piver-Rutledge class II) hysterectomy can improve survival and locoregional control compared to the standard extrafascial (Piver-Rutledge class I) hysterectomy. METHODS: Eligible patients (n = 520) with stage I endometrial cancer were randomized to class I or class II hysterectomy. Primary endpoint was overall survival. RESULTS: The median length of parametria and vagina removed were 15 and 5 vs. 20 mm and 15 mm for class I and class II hysterectomy, respectively (P > 0.001). Operating time and blood loss were statistically significantly higher for class II hysterectomy. At a median follow-up of 70 months, 51 patients had died. Five-year disease-free and overall survival were similar between arms (87.7 and 88.9% in the class I arm and 89.7 and 92.2% in the class II arm, respectively). The unadjusted hazard ratios for recurrence was 0.91 (95% confidence interval, 0.55-1.51, P = 0.72), and the hazard ratio for death was 0.77 (95% confidence interval, 0.44-1.33, P = 0.35). CONCLUSIONS: Class II hysterectomy did not improve locoregional control and survival compared to class I hysterectomy, but when an adequate vaginal cuff transection is not feasible with class I hysterectomy, a modified radical hysterectomy allows to obtain an optimal vaginal and pelvic control of disease with a minimal increase in surgical morbidity.

Patients with high-risk endometrial carcinoma (stage IcG3, IIG3 with myometrial invasion >50%, and III) receive adjuvant therapy after surgery but it is not clear whether radiotherapy (RT) or chemotherapy (CT) is better. We randomly assigned 345 patients with high-risk endometrial carcinoma to adjuvant CT (cisplatin (50 mg m(-2)), doxorubicin (45 mg m(-2)), cyclophosphamide (600 mg m(-2)) every 28 days for five cycles, or external RT (45-50 Gy on a 5 days week(-1) schedule). The primary end points were overall and progression-free survival. After a median follow-up of 95.5 months women in the CT group as compared with the RT group, had a no significant hazard ratio (HR) for death of 0.95 (95% confidence interval (CI), 0.66-1.36; P = 0.77) and a nonsignificant HR for event of 0.88 (95% CI, 0.63-1.23; P = 0.45). The 3, 5 and 7-year overall survivals were 78, 69 and 62% in the RT group and 76, 66 and 62% in the CT group. The 3, 5 and 7-year progression-free survivals were, respectively, 69, 63 and 56 and 68, 63 and 60%. Radiotherapy delayed local relapses and CT delayed metastases but these trends did not achieve statistical significance. Overall, both treatments were well tolerated. This trial failed to show any improvement in survival of patients treated with CT or the standard adjuvant radiation therapy. Randomised trials of pelvic RT combined with adjuvant cytotoxic therapy compared with RT alone are eagerly awaited.

Background: The role of systematic aortic and pelvic lymphadenectomy in patients with optimally debulked advanced ovarian cancer is unclear and has not been addressed by randomized studies. We conducted a randomized clinical trial to determine whether systematic aortic and pelvic lymphadenectomy improves progression-free and overall survival compared with resection of bulky nodes only. Methods: From January 1991 through May 2003, 427 eligible patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIB-C and IV epithelial ovarian carcinoma were randomly assigned to undergo systematic pelvic and para-aortic lymphadenectomy (n = 216) or resection of bulky nodes only (n = 211). Progression-free survival and overall survival were analyzed using a log-rank statistic and a Cox multivariable regression analysis. All statistical tests were two-sided. Results: After a median follow-up of 68.4 months, 292 events (i.e., recurrences or deaths) were observed, and 202 patients had died. Sites of first recurrences were similar in both arms. The adjusted risk for first event was statistically significantly lower in the systematic lymphadenectomy arm (hazard ratio [HR] = .75, 95% confidence interval [CI] = 0.59 to 0.94; P = .01) than in the no-lymphadenectomy arm, corresponding to 5-year progression-free survival rates of 31.2 and 21.6% in the systematic lymphadenectomy and control arms, respectively (difference = 9.6%, 95% CI = 1.5% to 21.6%), and to median progression-free survival of 29.4 and 22.4 months, respectively (difference = 7 months, 95% CI = 1.0 to 14.4 months). The risk of death was similar in both arms (HR = 0.97, 95% CI = 0.74 to 1.29; P = .85), corresponding to 5-year overall survival rates of 48.5 and 47%, respectively (difference = 1.5%, 95% CI = -8.4% to 10.6%), and to median overall survival of 58.7 and 56.3 months, respectively (difference = 2.4 months, 95% CI = -11.8 to 21.0 months). Median operating time was longer, and the percentage

Objective The purpose of this study was to explore in greater depth the outcomes of the Italian randomized trial investigating the role of pelvic lymphadenectomy in clinical early stage endometrial cancer. In the attempt to identify the patients with poorer prognosis, the impact of age and body mass index were also thoroughly investigated by cancer-specific survival (CSS) analyses. Study Design Survival outcomes of trial patients were analyzed in relation to age (>65 years and >65 years) in the 2 arms (lymphadenectomy and no lymphadenectomy) and in the whole population of the trial. Results Univariate and multivariable analyses of CSS and overall survival (OS) of patients showed that age >65 years is a strong independent poor prognostic factor (5-y OS 92.1% and 78.4% in >65 years and >65 years patients, respectively, P <.0001; 5-y CSS 93.8% and 83.5% in >65 years and >65 years patients, respectively, P =.003). Among women >65 years, node negative patients had 94.4% 5-y OS and 96.3% 5-y CSS vs 74.3% 5-y OS and 74.3% 5-y CSS for node positive patients (P =.009 and P =.002, respectively), while among women >65 y, node negative patients had 75.7% 5-y OS and 83.6% 5-y CSS vs 74.1% 5-y OS and 83.3% 5-y CSS for node positive patients (P =.55 and P =.58, respectively). Univariate and multivariable survival analyses in the whole trial population showed that older age, and higher tumor grade and stage were significantly associated to a worse prognosis. Conclusion Older women faced an intrinsic poorer survival whether or not they underwent lymphadenectomy, and, unexpectedly, irrespective of the presence of nodal metastasis. Only in older patients was obesity (body mass index >30) significantly associated with scarce prognosis. © 2014 Mosby, Inc. All rights reserved.

There is no clear consensus regarding systemic treatment of early-stage ovarian cancer (OC). Clinical trials are challenging because of the relatively low incidence and good prognosis. Initial results of the International Collaborative Ovarian Neoplasm (ICON)1 trial demonstrated benefit in both overall survival (OS) and recurrence-free survival (RFS) with adjuvant chemotherapy. We report results of 10-year follow-up to establish whether benefits are maintained longer term and discuss how this and other available evidence from randomised trials can be used to guide treatment options regarding the need for, and choice of, adjuvant chemotherapy regimen.

Background:The role of systematic aortic and pelvic lymphadenectomy (SAPL) at second-look surgery in early stage or optimally debulked advanced ovarian cancer is unclear and never addressed by randomised studies.Methods:From January 1991 through May 2001, 308 patients with the International Federation of Gynaecology and Obstetrics stage IA-IV epithelial ovarian carcinoma were randomly assigned to undergo SAPL (n=158) or resection of bulky nodes only (n=150). Primary end point was overall survival (OS).Results:The median operating time, blood loss, percentage of patients requiring blood transfusions and hospital stay were higher in the SAPL than in the control arm (P<0.001). The median number of resected nodes and the percentage of women with nodal metastases were higher in the SAPL arm as well (44% vs 8%, P<0.001 and 24.2% vs 13.3%, P:0.02). After a median follow-up of 111 months, 171 events (i.e., recurrences or deaths) were observed, and 124 patients had died. Sites of first recurrences were similar in both arms. The adjusted risk for progression and death were not statistically different (hazard ratio (HR) for progression=1.18, 95% confidence interval (CI)=0.87-1.59; P=0.29; 5-year progression-free survival (PFS)=40.9% and 53.8%; HR for death=1.04, 95% CI=0.733-1.49; P=0.81; 5-year OS=63.5% and 67.4%, in the SAPL and in the control arm, respectively).Conclusion:SAPL in second-look surgery for advanced ovarian cancer did not improve PFS and OS.British Journal of Cancer advance online publication, 2 August 2012; doi:10.1038/bjc.2012.336 www.bjcancer.com.

The purpose of this study was to investigate retrospectively the mRNA expression of genes involved in different DNA repair pathways implicated in processing platinum-induced damage in 171 chemotherapy-naïve ovarian tumours and correlate the expression of the different genes with clinical parameters. The expression of genes involved in DNA repair pathways (PARP1, ERCC1, XPA, XPF, XPG, BRCA1, FANCA, FANCC, FANCD2, FANCF and PolEta), and in DNA damage transduction (Chk1 and Claspin) was measured by RT-PCR in 13 stage I borderline and 77 stage I and 88 III ovarian carcinomas. ERCC1, XPA, XPF and XPG genes were significantly less expressed in stage III than in stage I carcinoma; BRCA1, FANCA, FANCC, FANCD2 gene expressions were low in borderline tumours, higher in stage I carcinomas and lower in stage III samples. High levels of ERCC1, XPA, FANCC, XPG and PolEta correlated with an increase in Overall Survival (OS) and Progression Free Survival (PFS), whilst high BRCA1 levels were associated with PFS on univariate analysis. With multivariate analyses no genes retained an association when adjusted by stage, grade and residual tumour. A tendency towards a better PFS was observed in patients with the highest level of ERCC1 and BRCA1 after platinum-based therapy than those given both platinum and taxol. The expression of DNA repair genes differed in borderline stage I, stage I and stage III ovarian carcinomas. The role of DNA repair genes in predicting the response in ovarian cancer patients seems far from being established.
