The role of lymphadenectomy in the management of early endometrial cancer remains controversial. In the recent ESMO-ESGO-ESTRO guidelines, lymphadenectomy is recommended for patients with endometrioid adenocarcinoma Grade 3 with deep myometrial invasion, but complete agreement was not achieved. In Sweden, DNA aneuploidy has been included as a high-risk factor. The aim of our study was to evaluate the impact of tumor histology, FIGO grade, DNA ploidy and myometrial invasion (MI) on occurrence of lymph node metastasis (LNM) in patients with endometrial cancer. The study design is a retrospective cohort study based on prospectively recorded register data. Endometrial cancer patients registered in the Swedish Quality Registry for Gynecologic Cancer 2010-2015 with FIGO Stages I-III and verified nodal status were included. Data on DNA ploidy, histology, FIGO grade and MI were included in multivariable log-binomial regression analyses with LNM as dependent variable. 1,165 cases fulfilled the inclusion criteria. The multivariable analyses revealed increased risk of LNM in patients with tumors with MI50% (risk ratio [RR]=4.1; 95% confidence interval [CI] 3.0-5.6), nonendometrioid compared to endometrioid histology (RR 1.8; CI 1.4-2.4) and FIGO Grade 3 compared to Grade 1-2 tumors (RR 1.5; CI 1.1-2.0). No statistically significant association between DNA ploidy status and LNM was detected. This population-based, nation-wide study in women with endometrial cancer confirms a strong association between MI50%, nonendometrioid histology and FIGO Grade 3, respectively, and LNM. DNA ploidy should not be included in the preoperative decision making of removing nodes or not. Whats new? Whether lymphadenectomy is beneficial for women with endometrial cancer remains uncertain. Moreover, additional studies are needed to explore factors that reliably predict lymph node metastasis (LNM).

PURPOSE: The single-arm OCTAVIA study evaluated front-line bevacizumab plus weekly paclitaxel and q3w carboplatin. PATIENTS AND METHODS: Patients with newly diagnosed ovarian cancer (International Federation of Gynecology and Obstetrics [FIGO] stage IIb-IV or grade 3/clear-cell stage I/IIA) received bevacizumab (7.5mg/kg, day 1), weekly paclitaxel (80 mg/m(2) days 1, 8, 15) and carboplatin (area under the curve 6 [AUC6], day 1) intravenously q3w for 6-8 cycles, followed by single-agent bevacizumab (total 1 year). The primary objective was to demonstrate median progression-free survival (PFS)>18 months according to the lower 90% confidence limit. Secondary end-points included objective response rate, overall survival, safety and tolerability. RESULTS: Most (74%) of the 189 treated patients had stage IIIC/IV disease, similar to the ICON7 population. Patients received a median of six chemotherapy and 17 bevacizumab cycles. At the predefined cutoff 24 months after last patient enrolment, 99 patients (52%) had progressed and 19 (10%) had died, all from ovarian cancer. Median PFS was 23.7 months (95% confidence interval [CI], 19.8-26.4 months), 1-year PFS rate was 85.6%, Response Evaluation Criteria in Solid Tumors (RECIST) response rate was 84.6% and median response duration was 14.7 months. Most patients (≥90%) completed at least six chemotherapy cycles. Grade ≥3 peripheral sensory neuropathy occurred in 5% and febrile neutropenia in 0.5%. Grade ≥3 adverse events typical of bevacizumab were no more common than in phase III bevacizumab ovarian cancer trials. There was one case of gastrointestinal perforation (0.5%) and no treatment-related deaths. CONCLUSION: OCTAVIA met its primary objective, demonstrating median PFS of approximately 2 years. This bevacizumab-containing regimen is active and tolerable.

OBJECTIVE: The recombinant fusion protein, aflibercept binds and neutralizes vascular endothelial growth factor (VEGF) A, B and placental growth factor (PlGF). Aflibercept inhibits ascites formation and reduces tumor burden in an ovarian cancer model. This open-label, single-arm, multicenter phase II study assessed the efficacy and safety of aflibercept in patients with advanced chemo-resistant epithelial ovarian cancer and symptomatic malignant ascites. METHODS: Patients who required≥3 previous paracenteses at 1-4 paracenteses per month received intravenous aflibercept 4mg/kg every 2weeks. The primary endpoint was repeat paracentesis response rate (RPRR), with response defined as at least a two-fold increase in time to repeat paracentesis compared with the baseline interval. RESULTS: Ten out of 16 enrolled patients achieved a response; the RPRR was 62.5% (95% CI 35.4%-84.8%). Aflibercept was considered effective based on a hypothesis that the RPRR was ≥60%. Median time to repeat paracentesis was 76.0 (95% CI 64.0-178.0) days, which was 4.5 times longer than the baseline interval (16.8days). Median progression-free survival was 59.5 (95% CI 41.0-83.0) days. Twelve patients experienced adverse events considered related to aflibercept treatment including hypertension (7 patients), headache, anorexia, and dysphonia (3 patients each). Two patients experienced Grade 3/4 treatment-related adverse events (Grade 3 hypertension and weight loss in one patient, Grade 3 intestinal perforation in one patient). CONCLUSION: Aflibercept 4mg/kg every 2weeks was effective at controlling malignant ascites, reducing the interval between repeat paracenteses. The safety profile was consistent with that reported for anti-VEGF agents., Objective: The recombinant fusion protein, aflibercept binds and neutralizes vascular endothelial growth factor (VEGF) A, B and placental growth factor (PlGF).

Introduction: Endometrial cancer patients with high grade tumours, deep myometrial invasion or advanced stage disease have a poor prognosis. Randomised studies have demonstrated the prevention of loco-regional relapses with radiotherapy (RT) with no effect on overall survival (OS). The possible additive effect of chemotherapy (CT) remains unclear. Two randomised clinical trials (NSGO-EC-9501/EORTC-55991 and MaNGO ILIADE-III) were undertaken to clarify if sequential combination of chemotherapy and radiotherapy improves progression-free survival (PFS) in high-risk endometrial cancer. The two studies were pooled. Methods: Patients (n = 540; 534 evaluable) with operated endometrial cancer International Federation of Obstetrics and Gynaecology (FIGO) stage I-III with no residual tumour and prognostic factors implying high-risk were randomly allocated to adjuvant radiotherapy with or without sequential chemotherapy. Results: In the NSGO/EORTC study, the combined modality treatment was associated with 36% reduction in the risk for relapse or death (hazard ratio (HR) 0.64, 95% confidence interval (CI) 0.41-0.99; P = 0.04); two-sided tests were used. The result from the Gynaecologic Oncology group at the Mario Negri Institute (MaNGO)-study pointed in the same direction (HR 0.61), but was not significant. In the combined analysis, the estimate of risk for relapse or death was similar but with narrower confidence limits (HR 0.63, CI 0.44-0.89; P = 0.009). Neither study showed significant differences in the overall survival. In the combined analysis, overall survival approached statistical significance (HR 0.69, CI 0.46-1.03; P = 0.07) and cancer-specific survival (CSS) was significant (HR 0.55, CI 0.35-0.88; P = 0.01). Conclusion: Addition of adjuvant chemotherapy to radiation improves progression-free survival in operated endometrial cancer patients with no residual tumour and a high-risk profile. A remaining question for future studies is if addition of radiotherapy to chemo

AIMS: To investigate if the pattern of cytotoxic drug sensitivity in vitro in patient samples of peritoneal carcinomatosis (PC) is supportive to the current standardized approach for drug selection for perioperative intraperitoneal chemotherapy (IPC). METHODS: The cytotoxic effect of cisplatin, oxaliplatin, irinotecan, 5-fluorouracil, mitomycin-C, doxorubicin and melphalan was investigated in vitro on tumour cells from 223 patient tumour samples of different PC origins. RESULTS: Considerable differences in cytotoxic drug sensitivity between tumour types of the PC entity and within each tumour type were observed. Cisplatin showed high cross-resistance with oxaliplatin but low cross-resistance with doxorubicin and irinotecan. No cross-resistance was found between irinotecan and doxorubicin. The dose-response relationships for melphalan and irinotecan in individual samples showed great variability. CONCLUSIONS: The activity in vitro of cytotoxic drugs commonly used in IPC for PC is very heterogeneous. Efforts for individualizing drug selection for PC patients undergoing IPC seem justified.

The significance of the PLAP (Placental alkaline phosphatase)/PLAP-like isozyme as tumour marker in relation to CA 125 and TPA for the monitoring of patients with malignant ovarian epithelial tumours was evaluated. Of all patients (n = 85), 40% had all three markers elevated. CA 125 being the most sensitive (60%), and the PLAP/PLAP-like isozyme and TPA both 40%. A tendency to certain tumour marker patterns of these three antigens in serum can be seen with regard to histopathology. Serous and anaplastic adenocarcinomas usually have all three markers moderately elevated, mucinous and mesonephric adenocarcinomas both have low incidences and low average levels of all three markers. Endometrioid and non-mucinous adenocarcinomas are often associated with high levels of the PLAP/PLAP-like isozyme and CA 125, while TPA shows moderate elevation. The PLAP/PLAP-like isozyme is positively correlated to tumour burden and the outcome of the disease. It may provide additional information on CA 125 in the monitoring of patients with ovarian cancer.
