RESUMEN
We have investigated a relational model of expectations and preferences among ovarian cancer patients centred on physician-patient communication, treatment approach, and the need for information. Consecutive patients anonymously filled in the EXPRESSION III questionnaire between 2009 and 2012. Following descriptive statistics, structural equation modelling was used to analyse the relationships between physician's evaluation by the patient (PEP), result of therapy (RT), need for changes in treatment (NCT) and patient's desire to be informed (PD). From a total of 108 patients, 53 (49.1%) knew their disease stage, 103 (95.4%) underwent surgery, 91 (84.3%) had chemotherapy and 51 (46.3%) relapsed. The final model demonstrated a good fit of data with fit indices >0.90. There was a significant positive effect of PEP on RT and a significant negative effect of PEP on NCT, with the final model explaining 84% of the NCT variance. Physicians represent the main point of contact, not only as a source of information about the disease and various treatment options, but also in the coping processes. As patients benefit from completeness of medical consultations, their awareness of the treatment outcome increases, while a negative perception of the physician leads to a desire to make changes in therapy.

PURPOSE: The management of high-risk endometrial cancer (HREC) remains controversial. We conducted a prospective multicenter phase-II clinical trial to evaluate an adjuvant chemotherapy (CT) with sequential radiotherapy (RT) in patients with HREC. METHODS: Patients with HREC from 8 institutions in Germany were enrolled. After surgery, patients received four cycles of paclitaxel 175 mg/m² (P) and carboplatin AUC5 (C) (d1, q21d) and subsequent external pelvic radiation therapy (1.8 Gy/d, d1-5) at a total dose of 45 Gy with vaginal brachytherapy (3 × 5 Gy). Quality of life (QoL) was assessed using the EORTC-QLQ-C30 questionnaire. Primary endpoints were tolerability, toxicity and QoL. Progression-free survival (PFS) was defined as secondary endpoint. RESULTS: Thirty-five patients were enrolled from 2004 through 2008. Median follow-up was 24 months (range 3-24 months). All patients received 4 cycles of P and C and completed RT. Overall, grade 3/4 haematological toxicity was 25.6 %. Three cycles were delayed because of leukopenia. Grade 3/4 non-haematologic toxicities were rare (≤3 %). No overall change in QoL occurred during treatment. Two-year median PFS and OS rates were both 75.8 %. CONCLUSIONS: Adjuvant combination CT with P + C and sequential RT is well tolerated and a feasible regimen in patients with HREC. Subsequent phase-III trials are warranted.

OBJECTIVE: Cytoreductive surgery and platinum-based systemic therapy constitute the standard treatment of patients with advanced ovarian cancer. The aim of the present study was to evaluate whether the time interval from surgery to start of chemotherapy has an impact on clinical outcome. METHODS: Data of 191 patients with advanced serous (FIGO III-IV) ovarian cancer from the prospective multicenter study OVCAD (OVarian CAncer Diagnosis) were analyzed. All patients underwent primary surgery followed by platinum-based chemotherapy. RESULTS: The 25%, 50%, and 75% quartiles of intervals from surgery to start of chemotherapy were 22, 28, and 38 days, respectively (range, 4-158 days). Preoperative performance status (P<0.001), extent of surgery (P<0.001), and perioperative complications (P<0.001) correlated with intervals from surgery to initiation of chemotherapy. Timing of cytotoxic treatment [≤ 28 days versus >28 days; hazard ratio (HR) 1.73 (95% confidence interval 1.08-2.78), P=0.022], residual disease [HR 2.95 (95% confidence interval 1.87-4.67), P<0.001], and FIGO stage [HR 2.26 (95% confidence interval 1.41-3.64), P=0.001] were significant prognostic factors for overall survival in multivariate analysis. While the interval from surgery to start of chemotherapy did not possess prognostic significance in patients without postoperative residual disease (n=121), it significantly correlated with overall survival in patients with postoperative residual disease [n=70, HR 2.24 (95% confidence interval 1.08-4.66), P=0.031]. CONCLUSION: Our findings suggest that delayed initiation of chemotherapy might compromise overall survival in patients with advanced serous ovarian cancer, especially when suboptimally debulked.

BACKGROUND: To evaluate surgical outcome and survival benefit after quaternary cytoreduction (QC) in epithelial ovarian cancer (EOC) relapse. METHODS: We systematically evaluated all consecutive patients undergoing QC in our institution over a 12-year period (October 2000-January 2012). All relevant surgical and clinical outcome parameters were systematically assessed. RESULTS: Forty-nine EOC patients (median age: 57; range: 28-76) underwent QC; in a median of 16 months (range:2-142) after previous chemotherapy. The majority of the patients had an initial FIGO stage III (67.3%), peritoneal carcinomatosis (77.6%) and no ascites (67.3%). At QC, patients presented following tumour pattern: lower abdomen 85.7%; middle abdomen 79.6% and upper abdomen 42.9%. Median duration of surgery was 292 min (range: a total macroscopic tumour clearance could be achieved. Rates of major operative morbidity and 30-day mortality were 28.6% and 2%, respectively.Mean follow-up from QC was 18.41 months (95% confidence interval (CI):12.64-24.18) and mean overall survival (OS) 23.05 months (95% CI: 15.5-30.6). Mean OS for patients without vs any tumour residuals was 43 months (95% CI: 26.4-59.5) vs 13.4 months (95% CI: 7.42-19.4); P=0.001. Mean OS for patients who received postoperative chemotherapy (n=18; 36.7%) vs those who did not was 40.5 months (95% CI: 27.4-53.6) vs 12.03 months (95% CI: 5.9-18.18); P<0.001.Multivariate analysis indentified multifocal tumour dissemination to be of predictive significance for incomplete tumour resection, higher operative morbidity and lower survival, while systemic chemotherapy subsequent to QC had a protective significant impact on OS. No prognostic impact had ascites, platinum resistance, high grading and advanced age. CONCLUSION: Even in this highly advanced setting of the third EOC relapse, maximal therapeutic effort combining optimal surgery and chemotherapy appear to significantly prolong survival in a selected patients 'group'.

Ovarian high-grade serous carcinoma (HGSC, type 2 ovarian carcinoma) is a poor prognosis cancer with limited therapeutic options. We aimed to investigate the expression pattern and prognostic potential of the metastasis-promoting protein anterior gradient 2 (AGR2) in primary HGSC. Immunohistochemistry was applied to a cohort of 124 primary HGSCs using tissue microarrays. Additionally, in 48 type 1 carcinomas (low-grade serous (LGSC), endometrioid (EC), clear cell (CCC), and mucinous carcinoma (MC)), AGR2 expression was investigated in an exploratory approach. A strong expression of AGR2 was seen in 15 HGSCs (12.1 %) and was significantly linked to shortened overall survival (OS, p = 0.011) and also for progression-free survival (PFS, p = 0.001) in the setting of adjuvant platinum-based chemotherapy (CTX). Multivariate survival analysis including age, stage, and residual tumor after surgery revealed that AGR2 expression was an independent prognostic marker for OS (p = 0.001) and PFS (p = 0.001) in HGSC. In type 1 carcinomas, AGR2 was significantly increased as compared to HGSC (p = 0.001) and was seen in subsets of all histological types, low-grade serous LGSC, EC, CCC, and MC. In particular, strong diffuse staining was seen in LGSC and MC. There was no association between AGR2 and estrogen receptor expression in ovarian type 1 or type 2 carcinomas. AGR2 expression identifies highly aggressive HGSC with a compromised prognosis for which novel therapeutic options are needed. Our data strongly support the further evaluation of AGR2 as a therapeutic target and a potential marker for response to platinum-based CTX in this tumor entity.

BACKGROUND: Overexpression of L1-cell adhesion molecule (L1CAM) has been observed for various carcinomas and correlates with poor prognosis and late-stage disease. In vitro, L1CAM enhances proliferation, cell migration, adhesion and chemoresistance. We tested L1CAM and interleukin-1 beta (IL-1ß) expression in tumor samples and ascitic fluid from ovarian carcinoma patients to examine its role as a prognostic marker. PATIENTS AND METHODS: We investigated tumor samples and ascitic fluid from 232 serous ovarian carcinoma patients for L1CAM by enzyme-linked immunosorbent assay. L1CAM expression was correlated with pathoclinical parameters and patients' outcome. IL-1ß levels were measured in tumor cell lysates. Ovarian cancer cell lines were analyzed for the contribution of L1CAM to IL-1ß production and nuclear factor 'kappa-light-chain-enhancer' of activated B-cells (NF-κB) activation. RESULTS: We observed that L1CAM-expressing tumors show a highly invasive phenotype associated with restricted tumor resectability at primary debulking surgery and increased lymphogenic spread. Soluble L1CAM proved to be a marker for poor progression-free survival and chemoresistance. In ovarian carcinoma cell lines, the specific knock-down of L1CAM reduces IL-1ß expression and NF-κB activity. CONCLUSIONS: L1CAM expression contributes to the invasive and metastatic phenotype of serous ovarian carcinoma. L1CAM expression and shedding in the tumor microenvironment could contribute to enhanced invasion and tumor progression through increased IL-1ß production and NF-κB activation.
