Validation of Androgen Receptor loss as a risk factor for the development of brain metastases from ovarian cancers.

Background: Central nervous system (CNS) spreading from epithelial ovarian carcinoma (EOC) is an uncommon but increasing phenomenon. We previously reported in a small series of 11 patients a correlation between Androgen Receptor (AR) loss and localization to CNS. Aims of this study were: to confirm a predictive role of AR loss in an independent validation cohort; to evaluate if AR status impacts on EOC survival.

Is an Actionable Mutation in High Grade Serous Ovarian Carcinoma.

Identifying cancer drivers and actionable mutations is critical for precision oncology. In epithelial ovarian cancer (EOC) the majority of mutations lack biological or clinical validation. We fully characterized 43 lines of Patient-Derived Xenografts (PDXs) and performed copy number analysis and whole exome sequencing of 12 lines derived from naïve, high grade EOCs.

Role of Mediterranean diet in preventing platinum based gastrointestinal toxicity in gynecolocological malignancies: A single Institution experience.

Background: Gynecological malignancies represent a major cause of death in women and are often treated with platinum-based regimens. Patients undergoing chemotherapy suffer from alterations in nutritional status which may worsen gastrointestinal (GI) toxicities, quality of life and affect the overall prognosis. Indeed, assuring a good nutritional status and limiting toxicities during treatment are still major goals for clinicians.

A Subset of Colorectal Cancers with Cross-Sensitivity to Olaparib and Oxaliplatin.

Purpose: Defects in the homologous recombination (HR) repair pathway are of clinical interest due to sensitivity of HR-deficient cells to PARP inhibitors. We were interested in defining PARP vulnerability in patients with metastatic colorectal cancer (mCRC) carrying and mutations who display poor prognosis, have limited therapeutic options, and represent an unmet clinical need.

Experimental Design: We tested colorectal cancer cell lines, patient-derived organoids (PDO), and patient-derived xenografts (PDX) enriched for and mutations for sensitivity to the PARP inhibitor olaparib, and the chemotherapeutic agents oxaliplatin and 5-fluorouracil (5-FU).

Role of Cyclin-Dependent Kinase Inhibitors in Endometrial Cancer.

Endometrial Cancer (EC) is an important cause of death in women worldwide. Despite early diagnosis and optimal treatment of localized disease, relapsed patients have few therapeutic options because after first line therapy, currently no standard of care exists. On the basis of endocrine positivity of most endometrioid ECs, Endocrine Therapy (ET) is a reasonable and widely accepted option.

Veliparib: a new therapeutic option in ovarian cancer?

The role of poly ADP ribose polymerase inhibitors in ovarian cancer is rapidly evolving. Three different poly ADP ribose polymerase inhibitors (olaparib, niraparib and rucaparib) have been already approved as maintenance after response to platinum-based chemotherapy; two of them (olaparib and rucaparib) also as single agents. Veliparib, a novel PARPI, showed promising results in preclinical and early clinical settings.

TOP2A as marker of response to pegylated lyposomal doxorubicin (PLD) in epithelial ovarian cancers.

Objective: Relapsed epithelial ovarian cancer (EOC) is frequently treated with pegylated liposomal doxorubicin (PLD). Unfortunately, most patients do not benefit from treatment. Prediction of response is crucial to optimize PLD use and avoid unnecessary toxicities.

A predictive score for optimal cytoreduction at interval debulking surgery in epithelial ovarian cancer: a two- centers experience.

Background: Optimal cytoreduction (macroscopic Residual Tumor, RT = 0) is the best survival predictor factor in epithelial ovarian cancer (EOC). It doesn't exist a consolidated criteria to predict optimal surgical resection at interval debulking surgery (IDS). The aim of this study is to develop a predictive model of complete cytoreduction at IDS.

PARP Inhibitors in Ovarian Cancer.

Background: Treatment of Epithelial Ovarian Cancer (EOC), historically based on surgery and platinum doublet chemotherapy, is associated with high risk of relapse and poor prognosis for recurrent disease. In this landscape, the innovative treatment with PARP inhibitors (PARPis) demonstrated an outstanding activity in EOC, and is currently changing clinical practice in BRCA mutant patients.

Objectives: The study aimed to highlight the mechanism of action, pharmacokinetics, clinical activity, indications and current strategies of development of Olaparib, Niraparib, Rucaparib, Talazoparib and Veliparib, the 5 most relevant PARPis.

Reprogramming T-cells for adoptive immunotherapy of ovarian cancer.

Introduction: Epithelial ovarian cancer (EOC) is the most common cause of death among gynecological malignancies. Despite surgical and pharmacological efforts to improve patients' outcome, persistent and recurrent EOC remains an un-eradicable disease. Chimeric associated antigens (CAR) T cells are T lymphocytes expressing an engineered T cell receptor that activate the immune response after an MHC unrestricted recognition of specific antigens, including tumor associated antigens (TAAs).

Checkpoint inhibitors in endometrial cancer: preclinical rationale and clinical activity.

Context: Treatment of advanced and recurrent endometrial cancer (EC) is still an unmet need for oncologists and gynecologic oncologists. The Cancer Genome Atlas Research Network (TCGA) recently provided a new genomic classification, dividing EC in four subgroups. Two types of EC, the polymerase epsilon (POLE)-ultra-mutated and the microsatellite instability-hyper-mutated (MSI-H), are characterized by a high mutation rate providing the rationale for a potential activity of checkpoint inhibitors.

Androgen receptor status predicts development of brain metastases in ovarian cancers.

Brain metastases are uncommon localizations in epithelial ovarian cancer (EOC), their reported incidence is increasing and no predictive biomarkers have been identified yet. Goals of this study were: i) to define a possible association between Estrogen Receptor (ER), Progesterone Receptor (PR), Androgen Receptor (AR),human EGF receptor 2 (HER2) and brain progression in EOC patients, and ii) to identify differences in ER, PR, AR and HER2 protein expression from primary EOC and its matched resected brain metastasis. A retrospective series of 11 EOC with matched brain metastasis surgically removed was collected.

Immune Checkpoint Inhibitors: A New Opportunity in the Treatment of Ovarian Cancer?

Epithelial ovarian cancer (EOC) is the leading cause of death for gynecological cancer. The standard treatment for advanced stage is the combination of optimal debulking surgery and platinum-based chemotherapy. Nevertheless, recurrence is frequent (around 70%) and prognosis is globally poor.

Adoptive immunotherapy against ovarian cancer.

The standard front-line therapy for epithelial ovarian cancer (EOC) is combination of debulking surgery and platinum-based chemotherapy. Nevertheless, the majority of patients experience disease recurrence. Although extensive efforts to find new therapeutic options, cancer cells invariably develop drug resistance and disease progression.

Xenopatients show the need for precision medicine approach to chemotherapy in ovarian cancer.

Platinum-based chemotherapy is the recommended first-line treatment for high-grade serous (HGS) epithelial ovarian cancer (EOC). However, most patients relapse because of platinum refractory/resistant disease. We aimed at assessing whether other drugs, commonly used to treat relapsed HGS-EOC and poorly active in this clinical setting, might be more effective against chemotherapy-naïve cancers.

Self-evaluation of Adjuvant Chemotherapy-Related Adverse Effects by Patients With Breast Cancer.

Importance: Patient perspective on chemotherapy-related adverse effects is being increasingly acknowledged both in experimental clinical trials and in clinical practice.

Objective: To evaluate a 10-item, paper questionnaire derived from the US National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 for patient-reported chemotherapy-related adverse effects.

Meningeal carcinomatosis underdiagnosis and overestimation: incidence in a large consecutive and unselected population of breast cancer patients.

Background: The incidence of meningeal carcinomatosis appears to be higher than in the past due to advances in neuro-imaging diagnostic techniques and improvements in cancer survival. Among solid tumors, breast cancer is the cancer most commonly associated with meningeal carcinomatosis, with an incidence rate of between 0.8 and 16%.

Overcoming endocrine resistance in metastatic breast cancer: Current evidence and future directions.

About 75% of all breast cancers are estrogen receptor (ER)-positive. They generally have a more favorable clinical behavior, prognosis, and pattern of recurrence, and endocrine therapy forms the backbone of treatment. Anti-estrogens (such as tamoxifen and fulvestrant) and aromatase inhibitors (such as anastrozole, letrozole, and exemestane) can effectively control the disease and induce tumor responses in a large proportion of patients.
