Current clinical practice and outcome of neoadjuvant chemotherapy for early breast cancer: analysis of individual data from 94,638 patients treated in 55 breast cancer centers

Neoadjuvant chemotherapy (NACT) is frequently used in patients with early breast cancer. Randomized controlled trials have demonstrated similar survival after NACT or adjuvant chemotherapy (ACT). However, certain subtypes may benefit more when NACT contains regimes leading to high rates of pathologic complete response (pCR) rates. In this study we analyzed data using the OncoBox research from 94,638 patients treated in 55 breast cancer centers to describe the current clinical practice of and outcomes after NACT under routine conditions. These data were compared to patients treated with ACT. 40% of all patients received chemotherapy. The use of NACT increased over time from 5% in 2007 up to 17.3% in 2016. The proportion of patients receiving NACT varied by subtype. It was low in patients with HR-positive/HER2-negative breast cancer (5.8%). However, 31.8% of patients with triple-negative, 31.9% with HR-negative/HER2-positive, and 26.5% with HR-positive/HER2-positive breast cancer received NACT. The rates of pCR were higher in patients with HR-positive/HER2-positive, HR negative/HER2-positive and triple-negative tumors (36, 53 and 38%) compared to HR-positive/HER2-negative tumors (12%). PCR was achieved more often in HER2-positive and triple-negative tumors over time. This is the largest study on use and effects of NACT in German breast cancer centers. It demonstrates the increased use of NACT based on recommendations in current clinical guidelines. An improvement of pCR was shown in particular in HER2-positive and triple-negative breast cancer, which is consistent with data from randomized controlled trails

Pulmonale Komplikationen beim erworbenen Immundefektsyndrom: Ergebnisse einer prospektiven Untersuchung

Höffken G, Lode H, Dissmann T, et al. Pulmonale Komplikationen beim erworbenen Immundefektsyndrom: Ergebnisse einer prospektiven Untersuchung. Deutsche medizinische Wochenschrift. 1988;113(19):755-762.Zwischen 1983 und 1987 wurde bei 37 von 100 HIV-Antikörper-positiven Patienten mit 40 bronchopulmonalen Infektionen prospektiv ein abgestuftes diagnostisches Programm durchgeführt, das im wesentlichen aus einer flexiblen Bronchoskopie, verbunden mit einer Lavage, transbronchialen Biopsie und (oder) bronchialem Bürstenabstrich, bestand. Unter Berücksichtigung sämtlicher intravitaler und autoptischer Untersuchungsverfahren hatten 25 der 37 Patienten eine Pneumocystis-carinii-Pneumonie (67,5 %), dreizehn Patienten bakterielle Pneumonien, davon sechs mykobakterielle Infektionen (atypische Mykobakterien n = 4), acht Patienten Neoplasien (pulmonales Kaposi-Sarkom n = 5, Plattenepithelkarzinom n = 2, M. Hodgkin n = 1) und vier Patienten eine Cytomegalievirus-Infektion. Die diagnostische Gesamtausbeute der flexiblen Bronchoskopie betrug 78 %, bezogen auf die Pneumocystis-Pneumonie 91 %.Between 1983 and 1987, a stepwise diagnostic programme was undertaken prospectively in 37 of 100 HIV-positive patients with 40 bronchopulmonary infections. It consisted chiefly of flexible bronchoscopy combined with lavage, transbronchial biopsy and/or removal of bronchial brush cells. Taking into account all examinations performed in life and at autopsy, 25 of the 37 patients had Pneumocystis carinii pneumonia (67.5 %), 13 had bacterial pneumonia, six of these were mycobacterial infections (atypical mycobacteria in four), eight had neoplasms (pulmonary Kaposi's sarcoma in five, squamous-cell carcinoma in two, and Hodgkin's disease in one), and four patients had cytomegalovirus infection. Total diagnostic success of bronchoscopy was 78 %; related to Pneumocystis pneumonia it was 91 %

Patient-reported outcomes and final overall survival results from the randomized phase 3 PENELOPE trial evaluating pertuzumab in low tumor human epidermal growth factor receptor 3 (HER3) mRNA-expressing platinum-resistant ovarian cancer

Introduction The PENELOPE trial evaluated pertuzumab added to chemotherapy for biomarker-selected platinum-resistant ovarian cancer. As previously reported, pertuzumab did not statistically significantly improve progression-free survival (primary end point: HR 0.74, 95% CI 0.50 to 1.11), although results in the paclitaxel and gemcitabine cohorts suggested activity. Here, we report final overall survival and patient-reported outcomes.Patients and methods Eligible patients had ovarian carcinoma that progressed during/within 6 months of completing >= 4 platinum cycles, low tumor human epidermal growth factor receptor 3 (HER3) mRNA expression, and 420mg every 3 weeks), stratified by selected chemotherapy, prior anti-angiogenic therapy, and platinum-free interval. Final overall survival analysis (key secondary end point) was pre-specified after 129 deaths. Patient-reported outcomes (secondary end point) were assessed at baseline and every 9 weeks until disease progression.Results At database lock (June 9, 2016), 130 (83%) of 156 randomized patients had died. Median follow-up was 27 months in the pertuzumab arm versus 26 months in the control arm. In the intent-to-treat population there was no overall survival difference between treatment arms (stratified HR 0.90, 95% CI 0.61 to 1.32; p=0.60). Results in subgroups defined by stratification factors indicated heterogeneity similar to previous progression-free survival results. Updated safety was similar to previously published results. Compliance with patient-reported outcomes questionnaire completion was >75% for all validated patient-reported outcomes measures. Pertuzumab demonstrated neither beneficial nor detrimental effects on patient-reported outcomes compared with placebo, except for increased diarrhea symptoms.Discussion Consistent with the primary results, adding pertuzumab to chemotherapy for low tumor HER3 mRNA-expressing platinum-resistant ovarian cancer did not improve overall survival, but showed trends in some cohorts. Except for increased diarrhea symptoms, pertuzumab had no impact on patient-reported outcomes.ClinicalTrials.gov: ClinicalTrials.gov: NCT01684878.Experimentele farmacotherapi
