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…
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 …
Topotecan (T) ± sorafenib (S) in platinum-resistant ovarian cancer (PROC): A double-blind placebo-controlled randomized NOGGO–AGO intergroup Trial—TRIAS.
5522Background: Sorafenib (S), a multi TK-inhibitor in combination with topotecan (T), a topoisomerase inhibitor showed preclinical synergistic effects in ovarian cancer but critical toxicity. To a...
Association between obesity and vulvar cancer recurrence: an analysis of the AGO-CaRE-1 study
ObjectiveObesity is associated with worse survival and an increased risk of relapse in several malignancies. The influence of obesity on vulvar cancer recurrence has not been previously described. The primary objective of this study was to evaluate the association between obesity and tumor recurrence in patients with vulvar cancer.MethodsThis is an analysis of the AGO-CaRE-1 study. Patients diagnosed with squamous cell vulvar cancer (stage IB and higher), treated in 29 cancer centers between January 1998 and December 2008, were registered in a centralized database. The cohort was divided into two gropus depending on the body mass index (BMI) (<30 vs ≥30 kg/m²). Descriptive statistics, su…
LION-PAW: Lymphadenectomy in ovarian neoplasm-pleasure ability of women—Prospective substudy of the randomized multicenter LION study.

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…
Lymph node ratio in inguinal lymphadenectomy for squamous cell vulvar cancer: Results from the AGO-CaRE-1 study.
Lymph node ratio (LNR) can predict treatment outcome and prognosis in patients with solid tumors. Aim of the present analysis was to confirm the concept of using LNR for assessing outcome in patients with vulvar cancer after surgery with inguinal lymphadenectomy in a large multicenter project.The AGO-CaRE-1 study multicenter database was used for analysis. LNR was defined as ratio of number of positive lymph nodes (LN) to the number of resected. Previously established LNR risk groups were used to stratify patients. LNR was investigated with respect to clinical parameters. Univariate and multivariable survival analyses were performed to assess the value of LNR in order to predict overall (OS…
