A Cross-Sectional Study of Patients' Satisfaction With Totally Implanted Access Ports.

BACKGROUND: Totally implanted access ports (PACs) are valuable tools for the treatment of patients with cancer because they ease the administration of chemotherapy, stem cells, and supportive care by reducing the rate of peripheral vein punctures. OBJECTIVES: The purpose of this study was to evaluate the satisfaction and impairments of activities of daily living of ambulatory patients with PAC systems receiving chemotherapy. METHODS: This cross-sectional, questionnaire-based study evaluated 202 patients with PAC systems in a comprehensive cancer center and cancer rehabilitation center. From November 2012 to August 2013, patients were invited to answer a questionnaire concerning quality of life and satisfaction with their PAC devices. Data regarding PAC-related complications were collected retrospectively by searching patients' medical history. FINDINGS: A total of 202 patients with 230 PAC devices were included. Median time from PAC implantation to inclusion in the study was nine months. Surgical complications occurred in some cases, with bleeding and hematoma being the most frequently observed events. Late complications consisted of infections, drug extravasation, PAC malposition, PAC malfunction, and thrombosis. A third of the patients reported that their PAC interfered with activities of daily living. However, most agreed that PAC systems alleviated the burden of chemotherapy administration, and the vast majority said they would choose the implantation of a PAC system for chemotherapy administration again.

Postoperative CMF Does Not Ameliorate Poor Outcomes in Women With Residual Invasive Breast Cancer After Neoadjuvant Epirubicin/Docetaxel Chemotherapy.

BACKGROUND: Neoadjuvant chemotherapy (NACT) is an accepted treatment approach in early-stage breast cancer. In contrast, the potential role of postneoadjuvant chemotherapy after taxane-containing NACT remains unclear. The aim of this study was to evaluate postneoadjuvant chemotherapy and further prognostic factors that predict outcome in women without pathologic complete remission (pCR). PATIENTS AND METHODS: A total of 377 patients with breast cancer who received preoperative chemotherapy were included in this retrospective study. Patients without standard NACT (6 cycles of epirubicin with docetaxel) or primary metastatic breast cancer and locally advanced, inoperable cancer were excluded from further analysis (n = 186). This resulted in a study population of 191 women (30 [15.7%] with pCR; 161 [84.3%] without pCR). Major outcome parameters were event-free survival (EFS) and overall survival (OS). The following parameters were tested for their prognostic role: postneoadjuvant chemotherapy, patient age, breast cancer subtype (luminal/HER2-negative tumors, HER2-positive tumors, and triple-negative tumors), histological grade, pCR, residual lymph node invasion, and residual invasive tumor size. RESULTS: At a median follow-up of 54 months, 51 disease relapses (26.7%) and 21 deaths (11%) were observed. In a comparison of patients with pCR with those without, no significant differences in EFS or OS were observed. Postneoadjuvant chemotherapy was significantly associated with shorter OS in patients without pCR. CONCLUSION: In this population, which included a high percentage of patients with luminal cancers, pCR did not predict for improved OS. Postneoadjuvant chemotherapy showed no discernible benefit even in subgroups with aggressive tumor biology or significant remaining tumor burden. The use of such treatment should therefore be discouraged outside of clinical trials.

Discrepancies between ESMO and NCCN breast cancer guidelines: An appraisal.

An ever growing number of medical organizations, societies, working groups and governmental agencies issue algorithms i.e. guidelines, of decision making flowcharts in diagnosis and treatment in a variety of diseases. In the field of evidence-based diagnosis and treatment of breast cancer, a large number of guidelines are available both from medical associations and national health departments. Among the most appreciated and utilized comprehensive guides is the European Society for Medical Oncology (ESMO) Breast Cancer Guidelines and from the other side of the Atlantic the National Comprehensive Cancer Network (NCCN) Guidelines in Breast Cancer. Although there is much concordance between the guidelines from these two organizations, it is intriguing to locate their discrepancies also. The aim of this report is to present a number of different points between ESMO and NCCN in the whole spectrum of breast cancer management, from prevention and diagnosis to treatment and follow up. This systematic review was performed in accordance with the PRISMA guidelines using a predefined search strategy and summarizes in detail, the differences between ESMO and NCCN guidelines regarding genetic risk evaluation and screening, surgery, chemotherapy, endocrine treatment, targeted biological agents, radiotherapy, pregnancy and fertility and follow-up.

Predictive molecular markers in metastases to the central nervous system: recent advances and future avenues.

Metastases to the central nervous system (CNS) are common in several cancer types. For most primary tumors that commonly metastasize to the CNS, molecular biomarker analyses are recommended in the clinical setting for selection of appropriate targeted therapies. Therapeutic efficacy of some of these agents has been documented in patients with brain metastases, and molecular testing of CNS metastases should be considered in the clinical setting. Here, we summarize the clinically relevant biomarker tests that should be considered in neurosurgical specimens based on the current recommendations of the European Society of Medical Oncology (ESMO) or the National Comprehensive Cancer Network (NCCN) for the most relevant primary tumor types: lung cancer (EGFR mutations, ALK rearrangement, BRAF mutations), breast cancer (HER2 amplification, steroid receptor overexpression), melanoma (BRAF mutations), and colorectal cancer (RAS mutations). Furthermore, we discuss emerging therapeutic targets including novel oncogenic alterations (ROS1 rearrangements, FGFR1 amplifications, CMET amplifications, and others) and molecular features of the tumor microenvironment (including immune-checkpoint molecules such as CTLA4 and PD-1/PD-L1). We also discuss the potential role of advanced biomarker tests such as next-generation sequencing and "liquid biopsies" for patients with CNS metastases.

BRCA-1 methylation and TP53 mutation in triple-negative breast cancer patients without pathological complete response to taxane-based neoadjuvant chemotherapy.

INTRODUCTION: Triple-negative breast cancer (TNBC) patients without pathological complete response (pCR) to neoadjuvant chemotherapy have an unfavourable prognosis. TNBC harbouring BRCA-1 germline mutations may be less responsive to taxanes, while sensitivity to DNA-damaging agents is retained. A similar effect was seen in tumours with epigenetic BRCA-1 silencing. Patients without pCR to neoadjuvant chemotherapy consisting of epirubicin plus docetaxel routinely received post-operative CMF at our centre. Here, we investigated the effect of adjuvant CMF in patients with or without BRCA-1 methylation or TP53 mutation. METHODS: DNA was extracted from formalin-fixed paraffin-embedded tissue. For determining BRCA-1 methylation status, quantitative methylation-specific PCR was performed. For the investigation of TP53 mutation status, DNA was PCR amplified and sequenced by Sanger sequencing. RESULTS: Twenty-four patients were included; BRCA-1 methylation was present in 41.7 %, while TP53 mutations were observed in 66.7 %. At a median follow-up of 27.5 months, 20 % of patients with BRCA-1 methylation had a disease-free survival (DFS) event, as compared to 64.3 % in the non-methylated group (p = 0.0472). Median DFS in the non-methylated group was 16 months and was not reached in the methylated group (n.s.). No association TP53 mutation status with clinical outcome was observed. CONCLUSIONS: Adjuvant CMF is of limited activity in TNBC refractory to taxane-based neoadjuvant chemotherapy. In this population, BRCA-1 methylation was associated with a significant decrease in DFS events suggesting a better prognosis and potentially retained activity of DNA-damaging agents.

Anemia is a significant prognostic factor in local relapse-free survival of premenopausal primary breast cancer patients receiving adjuvant cyclophosphamide/methotrexate/5-fluorouracil chemotherapy.

PURPOSE: To determine the effects of anemia on local relapse-free, relapse-free, and overall survival (LRFS, RFS, and OS, respectively) in premenopausal, primary breast cancer patients receiving adjuvant polychemotherapy, and to determine which conventional prognostic factors affected these outcomes. EXPERIMENTAL DESIGN: Four hundred twenty-four premenopausal patients with early-stage primary breast cancer and hormone receptor-expressing tumors were treated with i.v. cyclophosphamide/methotrexate/5-fluorouracil (CMF) polychemotherapy as part of an adjuvant phase III trial (Austrian Breast and Colorectal Cancer Study Group Trial 5). The influence of anemia (hemoglobin <12 g/dL) on LRFS, RFS, and OS was evaluated in a retrospective analysis. RESULTS: Of 424 patients, 77 (18.2%) developed anemia on CMF chemotherapy. After a median follow-up time of 5 years, 8.9% of nonanemic patients had local relapse compared with 19.6% of anemic patients (P=0.0006). Although mastectomy was associated with anemia (26% versus 13.7% in breast conserving surgery; P=0.002), multivariate analysis did not show mastectomy per se to be a significant risk factor for LRFS. Age, lymph node status, and hemoglobin had an independent significant influence on LRFS (P<0.005). Anemic patients had a relative risk of 2.96 (95% confidence interval, 1.41-6.23) for developing local relapse in comparison with nonanemic patients. CONCLUSION: Premenopausal breast cancer patients who developed anemia during the CMF regimen had significantly worse LRFS. In Austrian Breast and Colorectal Cancer Study Group Trial 5, anemia may have contributed to an almost doubled incidence of local recurrence in the chemotherapy arm. Molecular targets associated with tumor hypoxia and distinct from erythropoiesis should receive further attention in experimental and clinical settings.
