Introduction and objective: The approach to patients with advanced or metastatic high-grade epithelial ovarian cancer (EOC) has evolved over time with the advent of new therapies and multimodal strategies. The objective of this consensus of experts is to generate national recommendations for the profiling and management of advanced or metastatic high-grade OEC, defined as stages III and IV of the “The International Federation of Gynecology and Obstetrics (FIGO) classification at the time of diagnosis to base on the literature review that included international evidence-based clinical practice guidelines (CPG). Material and methods: Eleven panelists (oncologists and gynecological oncologists) answered 8 questions about the profiling and management of advanced or metastatic ovarian epithelial carcinoma.

Germline mutations of breast cancer susceptibility genes through expanded genetic analysis in unselected Colombian patients.

Background: In Colombia and worldwide, breast cancer (BC) is the most frequently diagnosed neoplasia and the leading cause of death from cancer among women. Studies predominantly involve hereditary and familial cases, demonstrating a gap in the literature regarding the identification of germline mutations in unselected patients from Latin-America. Identification of pathogenic/likely pathogenic (P/LP) variants is important for shaping national genetic analysis policies, genetic counseling, and early detection strategies.

Olaparib with or without bevacizumab versus bevacizumab plus a fluoropyrimidine as maintenance therapy in advanced colorectal cancer: The randomized phase 3 LYNK-003 study.

Background: The randomized, open-label, phase III LYNK-003 study assessed the efficacy of first-line maintenance olaparib, alone or in combination with bevacizumab, versus bevacizumab plus a fluoropyrimidine in participants with unresectable or metastatic colorectal cancer (mCRC). We present results of the prespecified interim futility analysis.

Methods: Eligible participants were ≥18 years of age with unresectable or mCRC that had not progressed after induction with first-line bevacizumab plus 5-fluorouracil plus oxaliplatin plus leucovorin (FOLFOX) or capecitabine plus oxaliplatin (CAPOX).

Recommendations on the treatment of metastatic hormone-sensitive prostate cancer: Patient selection.

The standard treatment for metastatic hormone-sensitive prostate cancer (mHSPC) is now a combination of androgen deprivation therapy plus an androgen receptor-targeted therapy (abiraterone, apalutamide, enzalutamide or darolutamide), with or without chemotherapy (docetaxel). The selection of suitable patients for each therapeutic approach has become a determining factor to ensure efficacy and minimize side effects. This article combines recent clinical evidence with the accumulated experience of experts in medical oncology, radiation oncology and urology, to provide a comprehensive view and therapeutic recommendations for mHSPC.

Management of Metastatic Urothelial Carcinoma in Emerging Markets (EM): An Expert Opinion.

Urothelial carcinoma (UC) is the 10 most common cancer globally with an almost 4 times higher prevalence in men. The main risk factors for development of urothelial carcinoma are advanced age, smoking, arsenic contamination, exposure to carcinogens. Metastatic urothelial carcinoma (mUC) has overall poor prognosis with a 5-year overall survival rate of only < 5%.

Use of concomitant proton pump inhibitors, statins or metformin in patients treated with pembrolizumab for metastatic urothelial carcinoma: data from the ARON-2 retrospective study.

Background: Concomitant medications may potentially affect the outcome of cancer patients. In this sub-analysis of the ARON-2 real-world study (NCT05290038), we aimed to assess the impact of concomitant use of proton pump inhibitors (PPI), statins, or metformin on outcome of patients with metastatic urothelial cancer (mUC) receiving second-line pembrolizumab.

Methods: We collected data from the hospital medical records of patients with mUC treated with pembrolizumab as second-line therapy at 87 institutions from 22 countries.

Impact of vaccination against COVID-19 on patients with cancer in ACHOC-C19 study: Real world evidence from one Latin American country.

During the pandemic, it has been recommended that vaccination against COVID-19 be a priority for patients with cancer; however, these patients were not included in the initial studies evaluating the available vaccines. To define the impact of vaccination against COVID-19 in preventing the risk of complications associated with the infection in a cohort of patients with cancer in Colombia. An analytical observational cohort study, based on national registry of patients with cancer and COVID 19 infection ACHOC-C19, was done.

Real-world evidence of nivolumab for non-small-cell lung cancer in a developing country.

Nivolumab is a human programmed death receptor-1 blocking antibody, used as treatment option in patients with advanced non-small-cell lung cancer (NSCLC). We assessed the nivolumab efficacy in terms of survival and response to treatment as second-line (2L) or third-line (3L) therapy in patients with advanced NSCLC. This is a multicentric observational study.

Frontline immune checkpoint inhibitor-based combination therapy in metastatic renal cell carcinoma patients with poor performance status.

Background: Immune checkpoint inhibitor-based combination therapy (ICI-based combination) is a new standard of care for metastatic clear cell renal cell carcinoma (mRCC) in the frontline setting. Patients with poor performance status (PS) (≥2) were excluded from pivotal trials. Hence, the activity and safety of ICI-based combination therapy in this group of patients is still unknown.

Genetic Study of Early Onset Parkinson's Disease in Cyprus.

Parkinson's Disease (PD) is a multifactorial neurodegenerative disease characterized by motor and non-motor symptoms. The etiology of PD remains unclear. However, several studies have demonstrated the interplay of genetic, epigenetic, and environmental factors in PD.

High-Dose Somatostatin Analogs for the Treatment of Neuroendocrine Neoplasms: where are we Now?

Neuroendocrine tumors (NET) represent a complex and heterogeneous group of malignancies arising from the diffuse endocrine cells and other cells derived from the neural crest. Advanced disease is observed at diagnosis in more than one-third of patients. Somatostatin analogs (SSA) are the cornerstone in advanced well-differentiated NET treatment.

Immune Checkpoint Inhibitor Combination Therapy versus Sunitinib as First-Line Treatment for Favorable-IMDC-Risk Advanced Renal Cell Carcinoma Patients: A Meta-Analysis of Randomized Clinical Trials.

Background: Novel combination therapies have been shown to improve the outcomes of treatment-naive patients with locally advanced or metastatic renal cell carcinoma (aRCC). However, the optimal systemic therapy for aRCC of favorable risk has yet to be clarified. We aimed to evaluate the efficacy and safety of different immunotherapy (IO) combinations, either with another IO (IO-IO) or with an antiangiogenic (IO-TKI), versus sunitinib in the first-line setting in aRCC patients with favorable IMDC risk.

Complete response and renal cell carcinoma in the immunotherapy era: The paradox of good news.

Immune-checkpoint inhibitor-based therapy has revolutionized the natural history of metastatic renal cell carcinoma (mRCC) providing better survival outcomes, higher rates of complete responses (CR) and durable remissions. Along with these advances, new challenges have emerged. RECIST and new immune-response criteria may be equivocal identifying complete responses.

Combination of statin/vitamin D and metastatic castration-resistant prostate cancer (CRPC): a post hoc analysis of two randomized clinical trials.

In castration-resistant prostate cancer (CRPC) patients, observational studies have reported that statins may boost the antitumor activity of abiraterone (AA) and data suggest an improvement in efficacy; conclusions with vitamin D are less clear but an eventual benefit has been pointed. We conducted a post hoc analysis of individual patient data of CRPC patients treated with prednisone and/or AA with or without statins/vitamin D on randomized clinical trials. In the COU-AA-301 trial, use of AA with statin and vitamin D reduced the risk of death by 38% (p = 0.

Circulating Tumor Cells as a Biomarker of Survival and Response to Radium-223 Therapy: Experience in a Cohort of Patients With Metastatic Castration-Resistant Prostate Cancer.

Introduction: Although increasing numbers of therapies with proven survival benefits have become available for metastatic castration-resistant prostate cancer (mCRPC), including radium-223, there is still a need for reliable biomarkers that provide information about clinically meaningful outcomes and treatment responses.

Materials And Methods: This study was a translational study that was conducted prospectively by the Spanish Oncology Genito-Urinary Group and included 45 patients with histologically confirmed mCRPC who were treated with radium-223. The primary response outcome was defined by a decline in circulating tumor cells (CTCs) of > 50% from baseline or a CTC count of ≤ 5 cells/7.

Urothelial cancer proteomics provides both prognostic and functional information.

Traditionally, bladder cancer has been classified based on histology features. Recently, some works have proposed a molecular classification of invasive bladder tumors. To determine whether proteomics can define molecular subtypes of  muscle invasive urothelial cancer (MIUC) and allow evaluating the status of biological processes and its clinical value.

Prognostic Significance of Venous Thromboembolic Events in Disseminated Germ Cell Cancer Patients.

Background: Disseminated germ cell cancers are at high risk of developing thromboembolic complications. We evaluated the prognostic value of venous thromboembolic events (VTE) in disseminated germ cell cancer.

Methods: Patients with germ cell cancer receiving upfront platinum-containing chemotherapy between 2004 and 2014 were pooled from the Spanish Germ Cell Cancer Group (SGCCG) registry and reviewed for the presence of VTE.

Analysis of polycyclic aromatic hydrocarbons (PAHs) in Lebanese surficial sediments: A focus on the regions of Tripoli, Jounieh, Dora, and Tyre.

This paper aims to identify the concentrations of PAHs in the sediments of four coastal zones in Lebanon and determine their possible sources and effects. For each region (Tripoli, Jounieh, Dora, and Tyre), sampling, lyophilization, Soxhlet extraction, rotary evaporation, and gas chromatography were performed on 11, 10, 7, and 11 samples, respectively. The total PAHs concentrations ranged from 1.

Well-Differentiated Grade 2, Type 3 Gastrointestinal Neuroendocrine Tumour with Bilateral Metastatic Ovarian Involvement: Report of an Unusual Case.

Treatment of metastatic gastric neuroendocrine tumours (NETs) is challenging. In oligometastatic cases, surgical resection is recommended whenever possible. Somatostatin analogues have been used to decrease gastrin levels, and available evidence suggests that these drugs can also reduce recurrences.

Leakage decrease detected by dynamic susceptibility-weighted contrast-enhanced perfusion MRI predicts survival in recurrent glioblastoma treated with bevacizumab.

Background And Purpose: In glioblastoma, tumor progression appears to be triggered by expression of VEGF, a regulator of blood vessel permeability. Bevacizumab is a monoclonal antibody that inhibits angiogenesis by clearing circulating VEGF, resulting in a decline in the contrast-enhancing tumor, which does not always correlate with treatment response. Our objectives were: (1) to evaluate whether changes in DSC perfusion MRI-derived leakage could predict survival in recurrent glioblastoma, and (2) to estimate whether leakage at baseline was related to treatment outcome.

GEINOFOTE: efficacy and safety of fotemustine in patients with high-grade recurrent gliomas and poor performance status.

Purpose: The treatment of recurrent high-grade gliomas (HGG) is controversial. There are different therapeutic schedules but without a clear orientation about which of them should be used in each clinical situation. In addition, when patients suffer a second recurrence or they have poor performance status, they are excluded from clinical trials, although second recurrences and poor performance status are indeed more and more real and common situations in the clinical setting.

Safety and efficacy of metronomic non-pegylated liposomal encapsulated doxorubicin in heavily pretreated advanced breast cancer patients.

Purpose: Metronomic administration of the same chemotherapy agents (lower doses with closer intervals) may optimize their antiangiogenic properties. The aim of our study was to determine the efficacy and safety of a metronomic regimen based in non-pegylated liposomal doxorubicin (NPLD) in advanced breast cancer patients.

Methods: Clinical records of patients with pretreated advanced breast cancer and who were treated with the Metronomic-Cooper-type regimen consisting of weekly fixed doses of NPLD (30 mg IV) plus 5-Fluorouracil (5-FU) (500 mg IV) plus vincristine (0.
