Metastatic pattern of breast cancer according to immunohistochemical defined subtypes in the transitional phase of adjuvant trastuzumab treatment.

e11581 Background: Prognosis of early breast cancer (BC) differs significantly upon subtypes (ST). Treatment with adjuvant trastuzumab improves outcome of HER2 overexpressing BC, however, less in k...

Excision repair cross-complementation group 1 protein overexpression as a predictor of poor survival for high-grade serous ovarian adenocarcinoma.

Abstract Objective The excision repair cross-complementation group 1 (ERCC1) expression is a predictor of survival after surgical treatment for several malignancies. Its overexpression has been reported as a marker of platinum resistance in lung cancer. However, the relevance of ERCC1 expression in ovarian cancer (OC) is the subject of controversy, both as a predictive parameter for platinum resistance and because of its association with poor prognosis. Therefore, we performed a retrospective study investigating ERCC1 expression and its correlation with patients' survival in OC. Methods We analyzed the ERCC1 protein expression using four different ERCC1 antibodies (clone 8F1) with different…

Sorafenib plus topotecan versus placebo plus topotecan for platinum-resistant ovarian cancer (TRIAS): a multicentre, randomised, double-blind, placebo-controlled, phase 2 trial.

Summary Background Antiangiogenic therapy has known activity in ovarian cancer. The investigator-initiated randomised phase 2 TRIAS trial assessed the multi-kinase inhibitor sorafenib combined with topotecan and continued as maintenance therapy for platinum-resistant or platinum-refractory ovarian cancer. Methods We did a multicentre, double-blind, placebo-controlled, randomised, phase 2 trial at 20 sites in Germany. Patients (≥18 years) with platinum-resistant ovarian cancer previously treated with two or fewer chemotherapy lines for recurrent disease were stratified (first vs later relapse) in block sizes of four and randomly assigned (1:1) using a web-generated response system to topotec…

Synchronous Ovarian and Endometrial Cancer—an International Multicenter Case-Control Study

ObjectivesThis study aimed to compare the prognosis of patients with synchronous endometrial and ovarian cancer (SEOC) to matched controls with either endometrial cancer (EC) or ovarian cancer (OC).MethodsA retrospective case-control study including all patients with SEOC who had been treated at 5 European tertiary gynecologic oncology centers between 1996 and 2011 and patients with either EC or OC matched for age, International Federation of Gynecology and Obstetrics (FIGO) stage, histology, year of diagnosis, and Eastern Cooperative Oncology Group performance score.ResultsThe study cohort comprised 77, 132, and 126 patients with SEOC, EC, and OC, respectively. The patient characteristics …

Incidence of bisphosphonate-associated osteonecrosis of the jaws in breast cancer patients.

BACKGROUND: Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ) is a relatively new disease. The aim of this study was to evaluate the prevalence of BP-ONJ in breast cancer patients with osseous metastasis and bisphosphonate therapy. METHODS: A retrospective study was conducted in a EUSOMA accredited breast unit in Germany. All patients treated from January of 2000 to March of 2006 with metastatic breast cancer and bisphosphonate therapy were reviewed. All patients were contacted, and missing data were completed through structured interviews with their dentists and physicians (n = 75). Primary outcome was the development of BP-ONJ and the detection of possible additional trigger fa…

A Phase 3 Trial of Bevacizumab in Ovarian Cancer

Angiogenesis plays a role in the biology of ovarian cancer. We examined the effect of bevacizumab, the vascular endothelial growth factor inhibitor, on survival in women with this disease.We randomly assigned women with ovarian cancer to carboplatin (area under the curve, 5 or 6) and paclitaxel (175 mg per square meter of body-surface area), given every 3 weeks for 6 cycles, or to this regimen plus bevacizumab (7.5 mg per kilogram of body weight), given concurrently every 3 weeks for 5 or 6 cycles and continued for 12 additional cycles or until progression of disease. Outcome measures included progression-free survival, first analyzed per protocol and then updated, and interim overall survi…

Is there any therapeutic role of pelvic and para-aortic lymphadenectomy in apparent early stage epithelial ovarian cancer?

Objective: The therapeutic role of pelvic and para-aortic lymphadenectomy in surgical staging of apparent early-stage epithelial ovarian cancer (eEOC) is still under debate. The aim of this study was to evaluate the potential therapeutic role of systematic lymphadenectomy in patients with eEOC. Methods: Multi-center retrospective cohort study, comparing women with apparent eEOC who underwent comprehensive bilateral pelvic and para-aortic lymphadenectomy (defined as ≥20 lymph nodes) versus patients receiving no lymphadenectomy or lymph node sampling, from 05/1985 to 12/2016. Patients with bulky nodes at CT-scan and those without complete intra-peritoneal surgical staging were excluded. Only …

Multiple independent variants at the TERT locus are associated with telomere length and risks of breast and ovarian cancer

Journal article TERT-locus SNPs and leukocyte telomere measures are reportedly associated with risks of multiple cancers. Using the Illumina custom genotyping array iCOGs, we analyzed ~480 SNPs at the TERT locus in breast (n = 103,991), ovarian (n = 39,774) and BRCA1 mutation carrier (n = 11,705) cancer cases and controls. Leukocyte telomere measurements were also available for 53,724 participants. Most associations cluster into three independent peaks. The minor allele at the peak 1 SNP rs2736108 associates with longer telomeres (P = 5.8 × 10!-7), lower risks for estrogen receptor (ER)-negative (P = 1.0 × 10!-8) and BRCA1 mutation carrier (P = 1.1 × 10!-5) breast cancers and altered promot…

Definitions for response and progression in ovarian cancer clinical trials incorporating RECIST 1.1 and CA 125 agreed by the Gynecological Cancer Intergroup (GCIG)

The Gynecological Cancer Intergroup (GCIG) has previously reached consensus regarding the criteria that should be used in clinical trial protocols to define progression-free survival after first-line therapy as well as the criteria to define response to treatment in recurrent disease using the serum marker CA 125 and has specified the situations where these criteria should be used. However, the publications did not include detailed definitions, nor were they written to accommodate the new version of Response Evaluation Criteria In Solid Tumors (RECIST) criteria (version 1.1) now available. Thus, we recommend that the definitions described later in detail are incorporated into clinical trial…
