BACKGROUND Chemotherapy for the treatment of maternal cancers during pregnancy has become more acceptable in the past decade; however, the effect of prenatal exposure to chemotherapy on cardiac and neurodevelopmental outcomes of the offspring is still uncertain. We aimed to record the general health, cardiac function, and neurodevelopmental outcomes of children who were prenatally exposed to chemotherapy. METHODS We did an interim analysis of a multicentre observational cohort study assessing children who were prenatally exposed to maternal cancer staging and treatment, including chemotherapy. We assessed children at birth, at age 18 months, and at age 5-6, 8-9, 11-12, 14-15, or 18 years. We did clinical neurological examinations, tests of the general level of cognitive functioning (Bayley or intelligence quotient [IQ] test), electrocardiography and echocardiography, and administered a questionnaire on general health and development. From age 5 years, we also did audiometry, the Auditory Verbal Learning Test, and subtasks of the Childrens Memory Scale, and the Test of Everyday Attention for Children, and we also completed the Child Behavior Checklist. This study is registered with ClinicalTrials.gov, number NCT00330447. FINDINGS 236 cycles of chemotherapy were administered in 68 pregnancies. We assessed 70 children, born at a median gestational age of 35·7 weeks (range 28·3-41·0; IQR 3·3; 47 women at <37 weeks), with a median follow-up period of 22·3 months (range 16·8-211·6; IQR 54·9). Although neurocognitive outcomes were within normal ranges, cognitive development scores were lower for children who were born preterm than for those born at full term. When controlling for age, sex, and country, the score for IQ increased by an average 11·6 points (95% CI 6·0-17·1) for each additional month of gestation (p<0·0001). Our measurements of the childrens behaviour, general health, hearing, and growth corresponded with those of the general population. Cardiac dimensions and functions were within normal ranges. We identified a severe neurodevelopmental delay in both members of one twin pregnancy. INTERPRETATION Fetal exposure to chemotherapy was not associated with increased CNS, cardiac or auditory morbidity, or with impairments to general health and growth compared with the general population. However, subtle changes in cardiac and neurocognitive measurements emphasise the need for longer follow-up. Prematurity was common and was associated with impaired cognitive development. Therefore, iatrogenic preterm delivery should be avoided when possible.

BACKGROUND Angiogenesis is a target in the treatment of ovarian cancer. Nintedanib, an oral triple angiokinase inhibitor of VEGF receptor, platelet-derived growth factor receptor, and fibroblast growth factor receptor, has shown activity in phase 2 trials in this setting. We investigated the combination of nintedanib with standard carboplatin and paclitaxel chemotherapy in patients with newly diagnosed advanced ovarian cancer. METHODS In this double-blind phase 3 trial, chemotherapy-naive patients (aged 18 years or older) with International Federation of Gynecology and Obstetrics (FIGO) IIB-IV ovarian cancer and upfront debulking surgery were stratified by postoperative resection status, FIGO stage, and planned carboplatin dose. Patients were randomly assigned (2:1) via an interactive voice or web-based response system to receive six cycles of carboplatin (AUC 5 mg/mL per min or 6 mg/mL per min) and paclitaxel (175 mg/m(2)) in addition to either 200 mg of nintedanib (nintedanib group) or placebo (placebo group) twice daily on days 2-21 of every 3-week cycle for up to 120 weeks. Patients, investigators, and independent radiological reviewers were masked to treatment allocation. The primary endpoint was investigator-assessed progression-free survival analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01015118. FINDINGS Between Dec 9, 2009, and July 27, 2011, 1503 patients were screened and 1366 randomly assigned by nine study groups in 22 countries: 911 to the nintedanib group and 455 to the placebo group. 486 (53%) of 911 patients in the nintedanib group experienced disease progression or death compared with 266 (58%) of 455 in the placebo group. Median progression-free survival was significantly longer in the nintedanib group than in the placebo group (17·2 months [95% CI 16·6-19·9] vs 16·6 months [13·9-19·1]; hazard ratio 0·84 [95% CI 0·72-0·98]; p=0·024). The most common adverse events were gastrointestinal (diarrhoea: nintedanib group 191 [21%] of 902 grade 3 and three [<1%] grade 4 vs placebo group nine [2%] of 450 grade 3 only) and haematological (neutropenia: nintedanib group 180 [20%] grade 3 and 200 (22%) grade 4 vs placebo group 90 [20%] grade 3 and 72 [16%] grade 4; thrombocytopenia: 105 [12%] and 55 [6%] vs 21 [5%] and eight [2%]; anaemia: 108 [12%] and 13 [1%] vs 26 [6%] and five [1%]). Serious adverse events were reported in 376 (42%) of 902 patients in the nintedanib group and 155 (34%) of 450 in the placebo group. 29 (3%) of 902 patients in the nintedanib group experienced serious adverse events associated with death compared with 16 (4%) of 450 in the placebo group, including 12 (1%) in the nintedanib group and six (1%) in the placebo group with a malignant neoplasm progression classified as an adverse event by the investigator. Drug-related adverse events leading to death occurred in three patients in the nintedanib group (one without diagnosis of cause; one due to non-drug-related sepsis associated with drug-related diarrhoea and renal failure; and one due to peritonitis) and in one patient in the placebo group (cause unknown). INTERPRETATION Nintedanib in combination with carboplatin and paclitaxel is an active first-line treatment that significantly increases progression-free survival for women with advanced ovarian cancer, but is associated with more gastrointestinal adverse events. Future studies should focus on improving patient selection and optimisation of tolerability. FUNDING Boehringer Ingelheim.

Linda Jm Oostendorp; Peep F. M. Stalmeier; A. Rogier T. Donders; Winette T. A. van der Graaf; P.B. Ottevanger

No standard monotherapy or combination palliative chemotherapy currently exists for patients with advanced breast cancer pretreated with anthracyclines and taxanes. In this systematic review we assess the current knowledge on the efficacy and safety of palliative single-agent chemotherapy drugs--capecitabine, vinorelbine, gemcitabine, and liposomal doxorubicin--commonly used in daily clinical practice. We identified 22 studies, of which ten investigated capecitabine, nine investigated vinorelbine, three investigated gemcitabine, and one investigated liposomal doxorubicin. The greatest amount of information was available for capecitabine and vinorelbine. These two drugs showed good efficacy. The disease control rate differed significantly between the four drugs, which is relevant in terms of how well tumour symptoms can be improved and whether quality of life can be maintained or even improved. To obtain more evidence of the efficacy and safety of chemotherapeutic agents used in this pretreated population of advanced breast cancer patients, randomised comparisons of the various drugs, as monotherapy and in combination with targeted agents, are needed.

Background:Despite growing attention to patient-centered care, the needs of cancer patients are not always met. Objective: Using a RAND modified Delphi method, this study aimed to systematically develop evidence-based indicators, to be used to measure the quality of patient-centered cancer care as a first step toward improvement. Methods:First, key recommendations were identified from literature and were distributed over 5 domains of patient-centered cancer care: communication, physical support, psychosocial care, after-care, and organization of care. Generic key recommendations, with best available evidence, were selected from guidelines. A multidisciplinary panel of patients and medical professionals (n = 14) rated and prioritized these recommendations in a written procedure. Subsequently, the panel discussed the recommendations at a consensus meeting. Results:Key recommendations were identified for communication (n = 32), physical support (n = 13), psychosocial care (n = 25), after-care (n = 11), and organization of care (n = 11). For all domains, recommendations based on high-level evidence were identified except for after-care and physical support. The panel developed 17 indicators concerning criteria for communication and informed consent, evaluation of communication skills, provision of information, examination of emotional health, appointment of a care coordinator, physical complaints, follow-up, rehabilitation, psychosocial effects of waiting times, and self-management. Conclusions: A set of 17 indicators for patient-centered cancer care resulted from this study. Evidence support was available for most indicators. Implications for Practice:This set provides an opportunity to measure and improve the quality of patient-centered cancer care. It is generic and therefore applies to many patients.

PURPOSE Early breast cancer survivors (BCSs) report high unmet care needs, and easily accessible care is not routinely available for this growing population. The Breast Cancer E-Health (BREATH) trial is a Web-based self-management intervention to support the psychological adjustment of women after primary treatment, by reducing distress and improving empowerment. PATIENTS AND METHODS This multicenter, randomized, controlled, parallel-group trial evaluated whether care as usual (CAU) plus BREATH is superior to CAU alone. BREATH is delivered in sixteen fully automated weekly modules covering early survivorship issues. Two to 4 months post-treatment, BCSs were randomly assigned to receive CAU + BREATH (n = 70) or CAU alone (n = 80) using a stratified block design (ratio 1:1). Primary outcomes were distress (Symptom Checklist-90) and empowerment (Cancer Empowerment Questionnaire), assessed before random assignment (baseline, T0) and after 4 (T1), 6 (T2), and 10 months (T3) of follow-up. Statistical (analysis of covariance) and clinical effects (reliable change index) were tested in an intention-to-treat analysis (T0 to T1). Follow-up effects (T0 to T3) were assessed in assessment completers. RESULTS CAU + BREATH participants reported significantly less distress than CAU-alone participants (-7.79; 95% CI, -14.31 to -1.27; P = .02) with a small-to-medium effect size (d = 0.33), but empowerment was not affected (-1.71; 95% CI, 5.20 to -1.79; P = .34). More CAU + BREATH participants (39 of 70 [56%]; 95% CI, 44.1 to 66.8) than CAU-alone participants (32 of 80 [40%]; 95% CI, 30.0 to 51.0) showed clinically significant improvement (P = .03). This clinical effect was most prominent in low-distress BCSs. Secondary outcomes confirmed primary outcomes. There were no between-group differences in primary outcomes during follow-up. CONCLUSION Access to BREATH reduced distress among BCSs, but this effect was not sustained during follow-up.

IMPORTANCE This is the first randomized placebo-controlled evaluation of a medical intervention for the prevention of trastuzumab-related cardiotoxic effects. OBJECTIVE To determine as the primary end point whether angiotensin II antagonist treatment with candesartan can prevent or ameliorate trastuzumab-related cardiotoxic effects, defined as a decline in left ventricular ejection fraction (LVEF) of more than 15% or a decrease below the absolute value 45%. DESIGN This randomized, placebo-controlled clinical study was conducted between October 2007 and October 2011 in 19 hospitals in the Netherlands, enrolling 210 women with early breast cancer testing positive for human epidermal growth factor receptor 2 (HER2) who were being considered for adjuvant systemic treatment with anthracycline-containing chemotherapy followed by trastuzumab. INTERVENTIONS A total of 78 weeks of candesartan (32 mg/d) or placebo treatment; study treatment started at the same day as the first trastuzumab administration and continued until 26 weeks after completion of trastuzumab treatment. MAIN OUTCOMES AND MEASURES The primary outcome was LVEF. Secondary end points included whether the N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) and high-sensitivity troponin T (hs-TnT) can be used as surrogate markers and whether genetic variability in germline ERBB2 (formerly HER2 or HER2/neu) correlates with trastuzumab-related cardiotoxic effects. RESULTS A total of 206 participants were evaluable (mean age, 49 years; age range, 25-69 years) 103 in the candesartan group (mean age, 50 years; age range, 25-69 years) and 103 in the placebo group (mean age, 50 years; age range, 30-67 years). Of these, 36 manifested at least 1 of the 2 primary cardiac end points. There were 3.8% more cardiac events in the candesartan group than in the placebo group (95% CI, -7% to 15%; P = .58): 20 events (19%) and 16 events (16%), respectively. The 2-year cumulative incidence of cardiac events was 0.28 (95% CI, 0.13-0.40) in the candesartan group and 0.16 (95% CI, 0.08-0.22) in the placebo group (P = .56). Candesartan did not affect changes in NT-proBNP and hs-TnT values, and these biomarkers were not associated with significant changes in LVEF. The Ala1170Pro homozygous ERBB2 genotype was associated with a lower likelihood of the occurrence of a cardiac event compared with Pro/Pro + Ala/Pro genotypes in multivariate analysis (odds ratio, 0.09; 95% CI, 0.02-0.45; P = .003). CONCLUSIONS AND RELEVANCE The findings do not support the hypothesis that concomitant use of candesartan protects against a decrease in left ventricular ejection fraction during or shortly after trastuzumab treatment in early breast cancer. The ERBB2 germline Ala1170Pro single nucleotide polymorphism may be used to identify patients who are at increased risk of trastuzumab-related cardiotoxic effects.

BACKGROUND About 15% of patients with endometrial cancer have high-risk features and are at increased risk of distant metastases and endometrial cancer-related death. We designed the PORTEC-3 trial to investigate the benefit of adjuvant chemoradiotherapy compared with radiotherapy alone for women with high-risk endometrial cancer. METHODS PORTEC-3 was a multicentre, open-label, randomised, international trial. Women with high-risk endometrial cancer were randomly allocated (1:1) to radiotherapy alone (48·6 Gy) in 1·8 Gy fractions five times a week or chemoradiotherapy (two cycles concurrent cisplatin 50 mg/m(2) and four adjuvant cycles of carboplatin area under the curve [AUC] 5 and paclitaxel 175 mg/m(2)) using a biased coin minimisation procedure with stratification for participating centre, lymphadenectomy, stage of cancer, and histological type. The primary endpoints of the PORTEC-3 trial were overall survival and failure-free survival analysed in the intention-to-treat population. This analysis focuses on 2-year toxicity and health-related quality of life as secondary endpoints; analysis was done according to treatment received. Health-related quality of life was assessed with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) the cervix cancer module and chemotherapy and neuropathy subscales of the ovarian cancer module at baseline, after radiotherapy and at 6, 12, 24, 36, and 60 months after randomisation. Adverse events were graded with Common Terminology Criteria for Adverse Events version 3.0. The study was closed on Dec 20, 2013, after achieving complete accrual, and follow-up remains ongoing for the primary outcomes analysis. This trial is registered with ISRCTN.com, number ISRCTN14387080, and with ClinicalTrials.gov, number NCT00411138. FINDINGS Between Sept 15, 2006, and Dec 20, 2013, 686 women were randomly allocated in the PORTEC-3 trial. Of these, 660 met eligibility criteria, and 570 (86%) were evaluable for health-related quality of life. Median follow-up was 42·3 months (IQR 25·8-55·1). At completion of radiotherapy and at 6 months, EORTC QLQ-C30 functioning scales were significantly lower (worse functioning) and health-related quality of life symptom scores higher (worse symptoms) for the chemoradiotherapy group compared with radiotherapy alone, improving with time. At 12 and 24 months, global health or quality of life was similar between groups, whereas physical functioning scores remained slightly lower in patients who received chemoradiotherapy compared with patients who received radiotherapy alone. At 24 months, 48 (25%) of 194 patients in the chemoradiotherapy group reported severe tingling or numbness compared with 11 (6%) of 170 patients in the radiotherapy alone group (p<0·0001). Grade 2 or worse adverse events were found during treatment in 309 (94%) of 327 patients in the chemoradiotherapy group versus 145 (44%) of 326 patients in the radiotherapy alone group, and grade 3 or worse events were found in 198 (61%) of 327 patients in the chemoradiotherapy group versus 42 (13%) of 326 patients in the radiotherapy alone group (p<0·0001), with most of the grade 3 adverse events being haematological (45%). At 12 and 24 months, no significant differences in grade 3 or worse adverse events were found between groups; only grade 2 or higher sensory neuropathy adverse events persisted at 24 months (25 [10%] of 240 patients in the chemoradiotherapy group vs one [<1%] of 247 patients in the radiotherapy alone group; p<0·0001). INTERPRETATION Despite the increased physician and patient-reported toxicities, this schedule of adjuvant chemotherapy given during and after radiotherapy in patients with high-risk endometrial cancer is feasible, with rapid recovery after treatment, but with persistence of patient-reported sensory neurological symptoms in 25% of patients. We await the analysis of primary endpoints before final conclusions are made.

EORTC-GCG process quality indicators for ovarian cancer surgery

L Verleye; P.B. Ottevanger; W.T.A. van der Graaf; Nick Reed; Ignace Vergote

INTRODUCTION Surgery is the mainstay of staging and treatment of ovarian cancer. Optimal quality of ovarian cancer surgery implies complete staging and removal of all macroscopic tumour with minimal harm to the patient in order to ensure best patient outcome. However, variation in the quality of ovarian cancer surgery is apparent. In order to assess and improve the quality of care, quality indicators can be used. METHODS To identify candidate quality indicators, a literature search was performed using relevant MESH terms. These were assessed for validity, feasibility and measurability. RESULTS Five quality indicators for staging of presumed early-stage ovarian cancer and six for primary debulking surgery for advanced disease are proposed. CONCLUSION The defined quality indicators can be used to monitor and improve the quality of surgery for ovarian cancer.

OBJECTIVE Methotrexate (MTX) alternating with folinic acid is a commonly used treatment regimen for low-risk gestational trophoblastic neoplasia (GTN). In The Netherlands, two courses of MTX are administered after normalization of serum human chorionic gonadotrophin (hCG) levels (consolidation courses), whereas in the United Kingdom, three consolidation courses are given. In a retrospective setting we compared relapse rates of women completing MTX therapy for low-risk GTN in The Netherlands and the UK. METHODS From 1980 to 2008, 351 patients were collected from the Dutch Central Registry for Hydatidiform Moles and records from the Dutch Working Party on Trophoblastic Disease. From the Charing Cross Hospital Trophoblast Disease Centre (London), 600 low-risk GTN patients were identified from 1992 to 2008. RESULTS In 4.0% of patients relapse occurred after MTX treatment with three consolidation courses, whereas 8.3% of patients relapsed after MTX treatment with two consolidation courses (p=0.006). Although patients from The Netherlands had a higher level of hCG (p<0.001) and more patients had metastases before the start of treatment (p=0.012), the number of courses of MTX to achieve a normal hCG did not differ significantly between patients from The Netherlands and the UK (p=0.375). CONCLUSIONS Relapse rates were higher in patients treated with two consolidation courses of MTX. Although other factors might have influenced the observed difference in relapse rates, three courses of consolidation chemotherapy may be preferable to two in the treatment of low-risk GTN in order to decrease the risk of disease relapse. A prospective randomized study would be required to confirm these findings.

This study was performed to obtain a comprehensive overview of the benefits and risks of second-line irinotecan monotherapy for advanced colorectal cancer. The literature was systematically reviewed to identify phase II and phase III trials that investigated the effect of second-line monotherapy with irinotecan. Thirty studies were included in this review: 25 phase II studies including 32 samples and five phase III studies including six samples. A disease control rate of greater than or equal to 50% was found in 23 out of 32 phase II samples, and one out of two phase III samples that reported disease control rate. Median time to progression was 2.7–6.0 months in phase II samples and 3.0–4.3 months in phase III samples. Median overall survival ranged from 6.6 to 16.1 months in phase II samples and 9.1–10.8 months in phase III samples. The most important severe adverse event in both phase II and phase III trials was diarrhea (5–39 and 15–36%, respectively), followed by nausea (1–24 and 5–14%), vomiting (2–22 and 6–14%), and asthenia (0–31 and 4–21%). Treatment-related mortality was 0–2% in phase II samples and 0–5% in phase III samples. Quality-of-life scores in phase II studies were associated with tumor response. In phase III studies, the quality of life while on treatment with irinotecan was similar to that of 5-fluorouracil, but better than supportive care alone. The quality of life on the weekly schedule was similar to the 3-weekly schedule. This study provides a comprehensive overview of the benefits and risks of second-line irinotecan. In general, second-line treatment with irinotecan is beneficial to patients.
