Perinatal and maternal outcomes at term in low-risk pregnancies according to NICE criteria: comparison between a tertiary obstetrical hospital and midwife-attended units.

PURPOSE: The aim of this study was to evaluate the perinatal and maternal outcomes at term at a single tertiary, university hospital in women with low-risk pregnancies. PATIENTS AND METHODS: We performed a retrospective cohort study of women with low-risk pregnancies, who delivered at University Women's Hospital Magdeburg between January 2010 and December 2014. Data were compared with data published by Brocklehurst et al. 2011. RESULTS: Of the 6052 women investigated, 2014 were classified as low risk according to the NICE criteria and were eligible for analysis. In 94.8%, a spontaneous vertex birth was observed. There were only 2 (0.1%) perinatal complications and 52 (2.5%) maternal complications. Ventouse delivery, forceps delivery, and caesarean sections were performed in 2.5, 1, and 3.1% of the cases, respectively. Episiotomy was performed in 37.7% of women. The third and fourth degree perineal trauma were observed in 0.3% of births investigated. Complications during the third stage of labour and blood transfusions were observed in 0.25 and 0.2%, respectively. In comparison with the births at home, we had lower rate of fetal complications for nulliparous women, but not for multiparous women, lower rate for blood transfusions, third and fourth degree perineal trauma and forceps delivery, and higher rate of spontaneous vertex birth, epidural analgesia, and episiotomy. The rate of vacuum extractions and caesarean sections were similar between both the places of birth. CONCLUSIONS: The tertiary-level obstetric unit is safe place of birth for women with low-risk pregnancies.

Neoadjuvant treatment with trastuzumab in HER2-positive breast cancer: results from the GeparQuattro study.

PURPOSE Trastuzumab, a humanized antibody against the human epidermal growth factor receptor type 2 (HER2), has shown high efficacy in breast cancer. We prospectively investigated its efficacy given simultaneously with anthracycline-taxane-based neoadjuvant chemotherapy. PATIENTS AND METHODS Patients with operable or locally advanced, HER2-positive tumors were treated preoperatively with four cycles of epirubicin/cyclophosphamide followed by four cycles of docetaxel with or without capecitabine (EC-T[X]) and trastuzumab 6 mg/kg (with a loading dose of 8 mg/kg) every 3 weeks during all chemotherapy cycles. Patients with HER2-negative tumors treated in the same study with the same chemotherapy but without trastuzumab were used as a reference group. Results Of 1,509 participants, 445 had HER2-positive tumors treated with trastuzumab and chemotherapy. Pathologic complete response (pCR; defined as no invasive or in situ residual tumors in the breast) rate was 31.7%, which was 16% higher than that in the reference group (15.7%). HER2-positive patients without response to the first four cycles of EC showed an unexpectedly high pCR rate of 16.6% (3.3% in the reference group). Breast conservation rate was 63.1% and comparable to that of the reference group (64.7%). EC-T(X) plus trastuzumab was associated with more febrile neutropenia and conjunctivitis, but with a comparable short-term cardiac toxicity profile as the reference group. CONCLUSION This trial confirms that combining trastuzumab with anthracycline-taxane-based neoadjuvant chemotherapy results in a high pCR rate without clinically relevant early toxicity. Combination of chemotherapy with trastuzumab should be considered when neoadjuvant treatment is given to patients with HER2-positive breast cancer.

Capecitabine in addition to anthracycline- and taxane-based neoadjuvant treatment in patients with primary breast cancer: phase III GeparQuattro study.

PURPOSE Capecitabine can be integrated either concomitantly or sequentially to anthracycline-plus-taxane-based regimens. PATIENTS AND METHODS Patients with large operable or locally advanced tumors, with hormone receptor-negative tumors, or with receptor-positive tumors but also clinically node-positive disease were recruited to receive preoperatively four cycles of epirubicin plus cyclophosphamide (EC; epirubicin 90 mg/m(2) and cyclophosphamide 600 mg/m(2)). Patients were then randomly assigned to four cycles of docetaxel (100 mg/m(2)), four cycles of docetaxel + capecitabine (TX; docetaxel 75 mg/m(2) plus capecitabine 1,800 mg/m(2)), or four cycles of docetaxel (75 mg/m(2)) followed by four cycles of capecitabine (1,800 mg/m(2); T-X). Patients with human epidermal growth factor receptor 2 (HER-2) -positive tumors received trastuzumab concomitantly with all cycles. Primary objectives were to assess the effect of docetaxel by comparing EC plus docetaxel versus EC plus TX and to assess the effect of duration by comparing EC plus TX versus EC plus T-X on pathologic complete response (pCR, without invasive/noninvasive breast tumor, regardless of nodal status) at surgery, irrespective of trastuzumab treatment. Results Of 1,509 patients starting EC, 1,421 were randomly assigned to docetaxel (n = 471), TX (n = 471), or T-X (n = 479). At surgery, pCR rates were 22.3%, 19.5%, and 22.3%, respectively; the difference for docetaxel (EC plus docetaxel v EC plus TX) was 2.8% (95% CI, -2.4% to 8.0%; P = .298).The difference for duration was -2.8% (95% CI, -8.0% to 2.4%; P = .298). Breast conservation rates were 70.1%, 68.4%, and 65.3%, respectively (P = .781 for docetaxel; P = .270 for duration). Concomitant but not sequential treatment with docetaxel was associated with more diarrhea; nail changes, and hand-foot-syndrome, but it was associated with less edema. CONCLUSION Adding capecitabine to or prolonging duration of neoadjuvant EC plus docetaxel does not result in higher efficacy at surgery.

Neoadjuvant vinorelbine-capecitabine versus docetaxel-doxorubicin-cyclophosphamide in early nonresponsive breast cancer: phase III randomized GeparTrio trial.

BACKGROUND: Among breast cancer patients, nonresponse to initial neoadjuvant chemotherapy is associated with unfavorable outcome. We compared the response of nonresponding patients who continued the same treatment with that of patients who switched to a well-tolerated non-cross-resistant regimen. METHODS: Previously untreated breast cancer patients received two 3-week cycles of docetaxel at 75 mg/m(2), doxorubicin at 50 mg/m(2), and cyclophosphamide at 500 mg/m(2) per day (TAC). Patients whose tumors did not decrease in size by at least 50% were randomly assigned to four additional cycles of TAC or to four cycles of vinorelbine at 25 mg/m(2) and capecitabine at 2000 mg/m(2) (NX). The outcome was sonographic response, defined as a reduction in the product of the two largest perpendicular diameters by at least 50%. A difference of 10% or less in the sonographic response qualified as noninferiority of the NX treatment. Pathological complete response was defined as no invasive or in situ residual tumor masses in the breast and lymph nodes. Toxic effects were assessed. All statistical tests were two-sided. RESULTS: Of 2090 patients enrolled in the GeparTrio study, 622 (29.8%) who did not respond to two initial cycles of TAC were randomly assigned to an additional four cycles of TAC (n = 321) or to four cycles of NX (n = 301). Sonographic response rate was 50.5% for the TAC arm and 51.2% for the NX arm. The difference of 0.7% (95% confidence interval = -7.1% to 8.5%) demonstrated noninferiority of NX (P = .008). Similar numbers of patients in both arms received breast-conserving surgery (184 [57.3%] in the TAC arm vs 180 [59.8%] in the NX arm) and had a pathological complete response (5.3% vs 6.0%). Fewer patients in the NX arm than in the TAC arm had hematologic toxic effects, mucositis, infections, and nail changes, but more had hand-foot syndrome and sensory neuropathy. CONCLUSION: Pathological complete responses to both regimens were marginal. Among patients who did not respond to the initial neoadjuvant TAC treatment, similar efficacy but better tolerability was observed by switching to NX than continuing with TAC.

A randomized clinical trial of cisplatin/paclitaxel versus carboplatin/paclitaxel as first-line treatment of ovarian cancer.

BACKGROUND: Despite considerable improvement in the treatment of advanced ovarian cancer, the optimization of efficacy and tolerability remains an important issue. Therefore, we performed a randomized, phase III non-inferiority trial comparing paclitaxel plus cisplatin (PT) with paclitaxel plus carboplatin (TC) in patients with advanced ovarian cancer. METHODS: A total of 798 patients with International Federation of Gynecology and Obstetrics stage IIB-IV were randomly assigned to receive six courses of either PT or TC at 3-week intervals. The primary endpoint was the proportion of patients without progression at 2 years. Secondary endpoints included toxicity, response to treatment, quality of life, and overall and progression-free survival time. Quality of life was evaluated using the European Organization for Research and Treatment of Cancer quality-of-life questionnaire (QLQ)-C30, version 2.0. Survival curves were calculated using the Kaplan-Meier method, and hazard ratios were estimated using the Cox proportional hazards model. RESULTS: The proportion of patients without progression at 2 years was not statistically significantly different between the two treatment arms (40.0% for PT versus 37.5% for TC, difference = 2.5%, one-sided 95% confidence interval [CI] = - infinity to 8.2%). Median progression-free survival time in the TC arm (17.2 months, 95% CI = 15.2 to 19.3 months) and the PT arm (19.1 months, 95% CI = 16.7 to 21.5 months) were also not statistically significantly different; the same was true of median overall survival time (43.3 months, 95% CI = 37.2 to 47.8 months versus 44.1 months, 95% CI = 40.2 to 49.4 months, for the TC and PT arms, respectively). The TC regimen was associated with a higher frequency of hematologic toxicity, but a lower frequency of gastrointestinal and neurologic toxicity, than the PT regimen. Mean global quality-of-life scores at the end of treatment were statistically significantly better in the TC arm than in the PT arm (65.25 versus 51.97, respectively; difference = -13.28, 95% CI = -18.88 to -7.68). CONCLUSION: The TC regimen achieved comparable efficacy to the PT regimen but was associated with better tolerability and quality of life, and should, therefore, be considered as an important alternative for standard first-line chemotherapy in patients with advanced ovarian cancer.
