Article Synopsis
  • The PROpel study showed that combining olaparib with abiraterone significantly improves progression-free survival in patients with metastatic castration-resistant prostate cancer (mCRPC), regardless of genetic mutation status.
  • This report presents safety analyses, revealing that olaparib plus abiraterone has notable adverse effects when compared to placebo plus abiraterone, particularly concerning anemia, nausea, and fatigue.
  • The most severe side effects occurred early in treatment, and a higher percentage of patients discontinued due to adverse events, especially anemia, when taking the olaparib combination.

Background: Preclinical and early clinical data suggest that the irreversible ErbB family blocker afatinib may be effective in urothelial cancers harbouring ERBB mutations.

Methods: This open-label, phase II, single-arm trial (LUX-Bladder 1, NCT02780687) assessed the efficacy and safety of second-line afatinib 40 mg/d in patients with metastatic urothelial carcinoma with ERBB1-3 alterations. The primary endpoint was 6-month progression-free survival rate (PFS6) (cohort A); other endpoints included ORR, PFS, OS, DCR and safety (cohorts A and B).

Background: In the FLIPPER trial, palbociclib/fulvestrant significantly improved progression-free survival (PFS) compared with placebo/fulvestrant in postmenopausal women with HR+/HER2- advanced breast cancer (ABC).

Objective: We assessed health-related quality of life (QoL) using patient-reported outcomes (PROs).

Design And Methods: In this phase II double-blinded study, PROs were assessed at baseline after every three cycles and at the end of the treatment using the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR23.

Among the side effects of anticancer treatment, chemotherapy-induced nausea and vomiting (CINV) is one of the most feared given its high prevalence, affecting up to 40% of patients. It can impair patient's quality of life and provoke low adherence to cancer treatment or chemotherapy dose reductions that can comprise treatment efficacy. Suffering CINV depends on factors related to the intrinsic emetogenicity of antineoplastic drugs and on patient characteristics.

Both cancer treatment and survival have significantly improved, but these advances have highlighted the deleterious effects of vascular complications associated with anticancer therapy. This consensus document aims to provide a coordinated, multidisciplinary and practical approach to the stratification, monitoring and treatment of cardiovascular risk in cancer patients. The document is promoted by the Working Group on Cardio Oncology of the Spanish Society of Cardiology (SEC) and was drafted in collaboration with experts from distinct areas of expertise of the SEC and the Spanish Society of Hematology and Hemotherapy (SEHH), the Spanish Society of Medical Oncology (SEOM), the Spanish Society of Radiation Oncology (SEOR), the Spanish Society of General and Family Physicians (SEMG), the Spanish Association of Specialists in Occupational Medicine (AEEMT), the Spanish Association of Cardiovascular Nursing (AEEC), the Spanish Heart Foundation (FEC), and the Spanish Cancer Association (AECC).

Background: In hormone receptor-positive, HER2-negative early stage breast cancer, cyclin-dependent kinases 4 and 6 (CDK4/6) inhibition in combination with endocrine therapy could represent an alternative to multiagent chemotherapy. We aimed to evaluate the biological and clinical activity of neoadjuvant ribociclib plus letrozole in the luminal B subtype of early stage breast cancer.

Methods: CORALLEEN is a parallel-arm, multicentre, randomised, open-label, phase 2 trial completed across 21 hospitals in Spain.

Bladder cancer is the fourth most common cancer in men and the ninth most common in women in the Western world. The management of bladder carcinoma requires a multidisciplinary approach. Optimal treatment depends on several factors, including histology, stage, patient status, and possible comorbidities.

Article Synopsis
  • - The study explored the relationship between circulating endothelial cells (CECs) in the blood and long-term benefits from first-line treatment in patients with metastatic clear cell renal cell carcinoma (ccRCC) to find predictors of treatment response.
  • - Conducted across 13 institutions, 75 adult patients were monitored over 15 months, revealing that higher baseline CEC levels correlated with significantly longer progression-free survival (22.2 months vs. 12.2 months) compared to lower levels.
  • - The findings indicate that elevated CEC levels under antiangiogenic treatment may serve as a useful indicator of clinical benefit, although no significant changes in CEC levels were observed at tumor progression.

Purpose: The Spanish Society of Medical Oncology (SEOM) has conducted a study on the access to oncologic drugs across the 17 Spanish Regions with the aim of identifying potential heterogeneities and making proposals for eliminating the barriers identified at the different levels.

Methods: An Expert Panel made up of medical oncologists designed a survey on certain indications approved for 11 drugs in the approach of breast cancer, melanoma, lung cancer, prostate cancer and support treatment. This survey was sent to 144 National Health System (NHS) hospitals.

Hyponatremia (Na ˂ 135 mmol/l) is the most frequent electrolyte disorder in clinical practice, and the syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the commonest cause of hyponatremia in cancer patients. Correcting hyponatremia in these patients can reduce morbidity and mortality, increase the response to anti-cancer agents, and help reduce hospital length of stay and costs. Tolvaptan is an oral medication used to treat SIADH-related hyponatremia patients that needs to be initiated at hospital so patients can have their serum sodium monitored.

A group of experts from the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) and the Spanish Society of Medical Oncology (SEOM) have reviewed in this paper the main aspects to be considered in the evaluation of patients with solid cancer and infectious diseases. They have established a series of recommendations on the prevention of the most prevalent infections in these patients, the use of vaccines, the control measures of vascular catheter infection and prevention of infections before certain surgical procedures. Also the criteria for management of febrile neutropenia and the use of colony-stimulating factors were revised.

Purpose: This study aims to determine the incidence of nausea and vomiting (CINV) after moderately emetogenic chemotherapy (MEC), under medical practice conditions and the accuracy with which physicians perceive CINV.

Methods: Chemotherapy-naive patients receiving MEC between April 2012 and May 2013 were included. Patients completed a diary of the intensity of nausea and number of vomiting episodes.

Pharmacogenomics is the study of how variation in the genetic background affects an individual's response to a specific drug and/or its metabolism. Using knowledge about the genes which produce the enzymes that metabolize a specific drug, a physician may decide to raise or lower the dose, or even change to a different drug. Targeted therapy with tyrosine kinase inhibitors (TKIs) and mammalian target of rapamycin (mTOR) inhibitors has led to a substantial improvement in the standard of care for patients with advanced or metastatic renal cell carcinoma (RCC).

Background: Maximum tolerated dose (MTD) chemotherapy followed by metronomic chemotherapy (low doses given on a frequent schedule) acts on tumour vascular endothelial cells by increasing the anti-tumour effect of anti-angiogenic agents. This multicentre, phase 2 study investigated the effectiveness of MTD gemcitabine combined with metronomic capecitabine plus the multikinase inhibitor sorafenib for the treatment of metastatic renal-cell carcinoma (RCC).

Methods: Patients were enrolled at eight centres across Spain between Dec 13, 2006, and April 17, 2008.
