RESUMEN
Purpose. Non-epithelial ovarian cancers (NEOCs) are rare diseases. Despite their overall good prognosis, the best management and current prognostic factors remain unclear. The objective of our study was to assess the clinical and pathological features of NEOC patients treated in our institution in the last 15 years and to explore risk factors for relapse and survival. Methods/patients. All patients with a pathological diagnosis of NEOC referred to the medical oncology department at Hospital Universitario Virgen del Rocio between 1999 and 2014 were included. Demographics, tumor characteristics, treatment procedures, and clinical follow-up were retrospectively collected. Risk factors for disease-free survival (DFS) and overall survival (OS) were assessed. Results. Fifty-seven patients were included, 33 (58 %) had a sex cord-stromal tumor (SCST) and 24 (42 %) had a germ-cell tumor (GCT). Median age, non-conservative surgery rates and DFS were lower in the GCT cohort; however, salvage chemotherapy led to a high proportion of complete responses in this group translating into a 90 % 3-year OS rate in both NEOC subtypes. The only identified risk factors statistically significant were stage and tumour relapse that associated, respectively, with DFS (HR = 8.84; 95 % CI 1.85-42) and OS (HR = 11.02; 95 % CI 1.76-68.7). Conclusions. Despite their rarity, NEOCs remain a highly curable group of neoplasm. In our series, a more conservative treatment approach in ovarian GCTs revealed comparable OS outcomes to SCST. No new risk factors that would help in patient stratification were identified (AU)

BACKGROUND: Induction chemotherapy followed by concurrent chemoradiation (CRT) (sequential therapy) has been evaluated in the treatment of locoregionally-advanced squamous cell cancer of the head and neck (LA-SCCHN), with docetaxel, cisplatin (P) and 5-flurouracil (F) shown to be superior to PF doublet. Nab-paclitaxel (A) is a novel albumin-bound paclitaxel with a superior therapeutic index to docetaxel. METHODS: A phase I trial [Clinical trials.gov identifier NCT00731380] to assess the safety and efficacy of nab-paclitaxel+cisplatin+5-fluorouracil (APF) as induction chemotherapy for three cycles, followed by concurrent carboplatin (area-under-curve (AUC) 1.5 weekly) with radiation therapy (RT) (70 Gy/35 fractions), was conducted using a 3+3 design in patients with previously untreated LA-SCCHN. Dose-limiting toxicities (DLTs) included: standard haematologic and non-haematologic toxicities, treatment delays, inability to complete ⩾95% of RT and skin/mucosal toxicity related to RT assessed from day 1 of treatment to 8 weeks after completion of CRT. RESULTS: 17 patients with oropharyngeal cancer were enrolled in three dose levels, with 15 patients evaluable for DLT. The median age was 54 years (range, 44-65 years), 14 patients were male, and 11 patients' tumours were p16 positive and four negative. Grade 3/4 adverse events during APF (%total number of cycles) were hyponatraemia (14%) neutropenia (10%), lymphopaenia (4%) and thrombocytopenia (2%) during 49 evaluable APF cycles. Febrile neutropenia occurred during one cycle of treatment. CONCLUSION: The recommended phase 2 dose of APF is nab-paclitaxel 100mg/m(2) days 1 and 8, cisplatin 75 mg/mg(2) day 1 and 5-fluorouracil 1000 mg/m(2)/day×96 h days 1-4, every 3 weeks, for three cycles prior to CRT.

Epithelial ovarian cancer (EOC) during pregnancy is a rare condition. The diagnosis and treatment strategies are therefore not well defined. The evidence is scarce and limited to small case reports or case series. In this review we describe the safety, utility and limitations of each diagnostic tool and surgical procedure in pregnant women with ovarian cancer. We also discuss the role of chemotherapy for ovarian cancer during pregnancy. Finally, we delineate different strategies of treatment according to the stage of the disease at diagnosis and gestational age. Due to the complexity of the management of EOC during pregnancy, patients should be referred to specialized centers. Gestational age at diagnosis, the initial surgical procedure, disease stage and patient's preferences are the key factors in the decision-making process to establish the best treatment strategy for each individual case (AU)

BACKGROUND: To evaluate the safety, pharmacokinetics (PKs), and pharmacodynamics of aflibercept, and to identify the recommended phase II dose (RP2D) of aflibercept in combination with pemetrexed and cisplatin. METHODS: Aflibercept was administered at escalating doses of 2, 4, or 6 mg kg(-1) in combination with fixed doses of pemetrexed (500 mg m(-2)) plus cisplatin (75 mg m(-2)) every 3 weeks. Blood samples were collected for PK analyses. Serum antiaflibercept antibodies were quantified to assess their impact on systemic aflibercept concentrations. RESULTS: Eighteen patients were enrolled. One patient dosed at 4 mg kg(-1) experienced grade 3 hypophosphatemia (dose-limiting toxicity; DLT), which prompted a cohort expansion. No further DLTs were observed in the 4 mg kg(-1) cohort or the 6 mg kg(-1) dose cohort. Most common adverse events (AEs) of all grades included (%): fatigue (89), anaemia (89), nausea (83), hyponatremia (78), and neutropenia (72). Grade ≥ 3 AEs consistent with anti-vascular endothelial growth factor therapy included (%): hypertension (22), pulmonary embolism (11), and deep vein thrombosis (6). Five patients (28%) experienced mild neurocognitive disturbance. No episodes of reversible posterior leukoencephalopathy syndrome (RPLS) were noted. CONCLUSION: The results of this phase I study allowed further evaluation of the combination of aflibercept with pemetrexed and cisplatin in a phase II study. The RP2D of aflibercept was 6 mg kg(-1), to be administered intravenously every 3 weeks in combination with pemetrexed and cisplatin.

The serum cancer antigen 125 (CA-125) remains a reliable biomarker in the therapeutic management of epithelial ovarian cancer (EOC). Monitoring the efficacy of cytotoxic chemotherapy (CT) and the early detection of relapse during the follow up of patients in remission represent the two most common clinical situations where the CA-125 has been successfully applied. There are however other scenarios along the course of the disease where the CA-125 can potentially aid in the decision-making process. Preoperative levels of CA-125 can help in selecting a subset of patients where an optimal cytoreduction may not be easily achieved. Perioperative variations in the CA- 125 levels after primary surgery and, more importantly, the nadir value of the CA-125 after primary chemotherapy, are associated with patient outcome. This review focuses on the clinical relevance of dynamic changes in CA-125 levels during the primary treatment of EOC and its potential influence both in the patient management and in the design of clinical trials in the adjuvant setting (AU)

Ovarian cancer is leading cause of gynecologic cancer mortality in Canada. To date, overall survival (os) has been the most-used endpoint in oncology trials because of its relevance and objectivity. However, as a result of various factors, including the pattern of sequential salvage therapies, measurement of os and collection of os data are becoming particularly challenging. Phase ii and iii trials have therefore adopted progression-free survival (pfs) as a more convenient surrogate endpoint; however, the clinical significance of pfs remains unclear. This position paper presents discussion topics and findings from a pan-Canadian meeting of experts that set out to evaluate the relevance of pfs as a valid endpoint in ovarian cancer;reach a Canadian consensus on the relevance of pfs in ovarian cancer; andtry to address how pfs translates into clinical benefit in ovarian cancer.Overall, the findings and the group consensus posit that future studies should ensure that trials are designed to evaluate pfs, os, and other clinically relevant endpoints such as disease-related symptoms or quality of life;incorporate interim futility analyses intended to stop accrual early when the experimental regimen is not active;stop trials early to declare superiority only when compelling evidence suggests that a new treatment provides benefit for a pre-specified, clinically relevant endpoint such as os or symptom relief; anddiscourage early release of secondary endpoint results when such a release might increase the frequency of crossover to the experimental intervention.
