Background Borderline tumors of the ovary (BOT) are a distinct entity of ovarian tumors, characterized by lack of stromal invasion. Recent studies postulated that the presence of invasive implants, incomplete staging, fertility sparing surgery and residual tumor after surgery are major prognostic factors for BOT. There are no biomarkers that can predict BOT or the presence of invasive implants. Objective The aim of our study was to assess the value of CA125 and HE4 alone, or within ROMA score for detecting BOT, and for predicting the presence of invasive implants. Methods Retrospective, monocentric study on 167 women diagnosed with BOT or benign ovarian masses. Serum HE4, CA125 levels and ROMA were assessed preoperatively. Due to low number of BOT with invasive implants, we performed an unmatched analysis (consecutive patients) and a matched analysis (according to age and histology) to compare BOT with invasive implants, BOT without invasive implants and benign disease. Results There were no significant differences in the HE4 and CA125 expressions in the three groups of patients (p = 0.984 and p = 0.141, respectively). The ROC analysis showed that CA125 alone is superior to ROMA and HE4 in discriminating patients with BOT with invasive implants from patients with benign diseases and BOT without invasive implants. A newly established score, ROMABOT, did not perform better than ROMA. The analysis of the matched groups revealed similar results as the analysis of all samples. Conclusions Both HE4 and CA125 are not reliable biomarkers for the diagnosis of BOT or for predicting the presence of invasive implants. [ABSTRACT FROM AUTHOR]

Background: Approximately one third of women diagnosed with ovarian cancer is 70 years or older. Information on the treatment reality of these elderly patients is limited. Methods: 275 patients with primary epithelial ovarian cancer FIGO stage II-IV undergoing cytoreductive surgery and platinum-based chemotherapy were prospectively included in this European multicenter study. Patients <70 and ⩾70 years were compared regarding clinicopathological variables and prognosis. Results: Median age was 58 years (18-85); 47 patients (17.1%) were 70 years or older. The postoperative 60-day -mortality rate was 2.1% for elderly and 0.4% for younger patients (p < 0.001). Elderly patients were less likely to receive optimal therapy (no residual disease after surgery and platinum combination chemotherapy) compared to patients <70 years (40.4% vs. 70.1%, p < 0.001) and their outcome was less favorable regarding median PFS (12 vs. 20 months, p = 0.022) and OS (30 vs. 64 months, p < 0.001). However, in multivariate analysis age itself was not a prognostic factor for PFS while the ECOG performance status had prognostic significance in elderly patients. Conclusions: Elderly patients with ovarian cancer are often treated less radically. Their outcome is impaired despite no consistent prognostic effect of age itself. Biological age and functional status should be considered before individualized treatment plans are defined. [ABSTRACT FROM AUTHOR]

Background: The role of the tumor necrosis factor receptor associated protein 1 (TRAP1) – supposed to be involved in protection of cells from apoptosis and oxidative stress – has just started to be investigated in ovarian cancer. TRAP1 has been shown to be estrogen up-regulated in estrogen receptor α (ERα) positive ovarian cancer cells. The clinical impact of TRAP1 is not clear so far and the significance of ERα expression as therapeutic and prognostic marker is still controversial. Therefore, we investigated the importance of TRAP1 together with ERα in regard to clinicopathological parameters, chemotherapy response, and survival. Methods and results: Expressions of TRAP1 and ERα were evaluated by immunohistochemical staining of tissue microarrays comprised of 208 ovarian cancer samples. TRAP1 was highly expressed in 55% and ERα was expressed in 52% of all cases. High TRAP1 expression correlated significantly with ERα (p < 0.001) but high TRAP1 expression was also found in 42% of ERα negative cases. High TRAP1 expression correlated significantly with favorable chemotherapy-response (HR = 0.48; 95%CI 0.24-0.96, p=0.037) and showed a significant impact on overall survival (OS) (HR = 0.65; 95%CI 0.43-0.99, p = 0.044). ERα expression was a favorable prognostic factor for OS in univariate and multivariate analyses. Interestingly, the combined pattern (ERα positive and/or TRAP1-high) revealed the strongest independent and significant positive influence on OS (HR = 0.41; 95%CI 0.27-0.64). Conclusion: Immunohistochemical evaluation of TRAP1 together with ERα provides significant prognostic information. TRAP1 alone is significantly associated with chemotherapy response and overall survival, rendering TRAP1 as interesting scientific and therapeutic target. [ABSTRACT FROM AUTHOR]

Background: Palliative systemic treatment in elderly gynaecological cancer patients remains a major challenge. In recurrent ovarian cancer (ROC), treosulfan an active alkylating drug showed similar cytotoxicity whether as oral (p.o.) or intravenous (i.v.) application. The aim of this innovative trial was to evaluate the preference of elderly patients (≥65 years) for p.o. or i.v. chemotherapy focusing compliance, outcome, toxicities, and geriatric aspects as secondary endpoints., Methods: Patients with ROC had the free choice between treosulfan i.v. (7000 mg/m 2 d1, q29d) or p.o. (600 mg/m 2 daily d1-28, q57d). Only indecisive participants were randomized., Results: Overall 123 patients with 2 nd to 5 th recurrence were registered and 119 received at least one cycle of chemotherapy. 85.7% preferred treosulfan i.v. and 14.3% oral, where only three patients were randomized. Main reasons for i.v. preference associated with individual expectations of lower rate of gastrointestinal disorders, higher activity and tolerability of treatment. Median of applied chemotherapies was three (range 1-12 cycles), with most common grade 3/4 toxicities thrombopenia (18.7%), leukopenia (15.7%), ascites (7.6%), bowel obstruction (6.7%), and abdominal pain (4.2%). Median time until progression/overall survival was 5.2/7.8 months (i.v.), and 5.6/10.4 months (p.o.), respectively, without significant differences in efficacy., Conclusions: Elderly patients with recurrent ovarian cancer asked and demonstrated active participation in the decision-making process of their oncological treatment and favoured predominantly the i.v. application. Treosulfan was generally well-tolerated despite comorbidities and heavy pre-treatment. Our study demonstrates that patients' preference did not influence prognosis negatively and remains important in gynaecologic oncology decision practice., Eudract Nr: 2004-000719-25; NCT 00170690.
