Preventing alpelisib-related hyperglycaemia in HR+/HER2-/-mutated advanced breast cancer using metformin (METALLICA): a multicentre, open-label, single-arm, phase 2 trial.

Background: Hyperglycaemia is an early and frequent adverse event during alpelisib treatment. METALLICA aimed to evaluate prophylactic metformin to prevent or reduce hyperglycaemia occurrence in patients with HR+/HER2-/-mutated advanced breast cancer (ABC).

Methods: Between August 13th, 2020 and March 23rd, 2022, this 2-cohort, phase 2, multicentre, single-arm trial (NCT04300790) enrolled patients with HR+/HER2-/PIK3CA-mutated ABC: cohort A, normal glycaemia (fasting plasma glucose <100 mg/dL [<5.

Use of multi-gene panels in patients at high risk of hereditary digestive cancer: position statement of AEG, SEOM, AEGH and IMPaCT-GENÓMICA consortium.

This position statement, sponsored by the Asociación Española de Gastroenterología, the Sociedad Española de Oncología Médica, the Asociación Española de Genética Humana and the IMPaCT-Genómica Consortium aims to establish recommendations for use of multi-gene panel testing in patients at high risk of hereditary gastrointestinal and pancreatic cancer. To rate the quality of the evidence and the levels of recommendation, we used the methodology based on the GRADE system (Grading of Recommendations Assessment, Development and Evaluation). We reached a consensus among experts using a Delphi method.

Safety and efficacy of ribociclib plus letrozole in patients with HR+, HER2- advanced breast cancer: Results from the Spanish sub-population of the phase 3b CompLEEment-1 trial.

Background: Breast cancer is the most common malignancy and the second leading cause of cancer-related mortality in Spanish women. Ribociclib in combination with endocrine therapy (ET) has shown superiority in prolonging survival in patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC) vs. ET alone.

Pre-operative ribociclib plus letrozole versus chemotherapy: Health-related quality of life outcomes from the SOLTI CORALLEEN trial.

Introduction: In the phase II CORALLEEN trial, patients with PAM50 luminal B early breast cancer (EBC) were randomised to neoadjuvant ribociclib plus letrozole (R + L) or chemotherapy based on anthracyclines and taxanes. Results from the primary efficacy analysis showed a similar proportion of patients with response at surgery in both groups. How health-related quality of life (HRQoL) outcomes with R + L compare with chemotherapy in EBC setting is still unknown.

Sapanisertib plus Fulvestrant in Postmenopausal Women with Estrogen Receptor-Positive/HER2-Negative Advanced Breast Cancer after Progression on Aromatase Inhibitor.

Purpose: This phase II study investigated daily or weekly sapanisertib (a selective dual inhibitor of mTOR complexes 1 and 2) in combination with fulvestrant.

Patients And Methods: Postmenopausal women with estrogen receptor-positive (ER+)/HER2-negative (HER2-) advanced or metastatic breast cancer following progression during/after aromatase inhibitor treatment were randomized to receive fulvestrant 500 mg (28-day treatment cycles), fulvestrant plus sapanisertib 4 mg daily, or fulvestrant plus sapanisertib 30 mg weekly, until progressive disease, unacceptable toxicity, consent withdrawal, or study completion.

Results: Among 141 enrolled patients, baseline characteristics were balanced among treatment arms, including prior cyclin-dependent kinase-4/6 (CDK4/6) inhibitor treatment in 33% to 35% of patients.

Health-related quality of life with palbociclib plus endocrine therapy versus capecitabine in postmenopausal patients with hormone receptor-positive metastatic breast cancer: Patient-reported outcomes in the PEARL study.

Background: The PEARL study showed that palbociclib plus endocrine therapy (palbociclib/ET) was not superior to capecitabine in improving progression-free survival in postmenopausal patients with metastatic breast cancer resistant to aromatase inhibitors, but was better tolerated. This analysis compared patient-reported outcomes.

Patients And Methods: The PEARL quality of life (QoL) population comprised 537 patients, 268 randomised to palbociclib/ET (exemestane or fulvestrant) and 269 to capecitabine.

Real-world effectiveness of dual HER2 blockade with pertuzumab and trastuzumab for neoadjuvant treatment of HER2-positive early breast cancer (The NEOPETRA Study).

Purpose: Neoadjuvant clinical trials with dual HER2 blockade with pertuzumab and trastuzumab plus chemotherapy demonstrated high rates of pathological complete response (pCR) in HER2-positive early breast cancer (BC). We investigated whether the benefit on pCR seen in clinical trials is confirmed in a real-world setting.

Methods: Multicenter, retrospective study in patients with HER2-positive early BC receiving neoadjuvant treatment with pertuzumab and trastuzumab in routine clinical practice (n = 243).

Ribociclib plus letrozole versus chemotherapy for postmenopausal women with hormone receptor-positive, HER2-negative, luminal B breast cancer (CORALLEEN): an open-label, multicentre, randomised, phase 2 trial.

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.

Multicenter retrospective study to evaluate the impact of trabectedin plus pegylated liposomal doxorubicin on the subsequent treatment in women with recurrent, platinum-sensitive ovarian cancer.

Debulking surgery, followed by taxane/platinum-based chemotherapy has traditionally been the first-line treatment for advanced ovarian cancer. However, most patients will experience recurrence afterwards, and receive subsequent lines of therapy. It has been proposed that extending the treatment-free interval of platinum can improve the response to a subsequent platinum-based chemotherapy, and reduce associated toxicities in women with recurrent, platinum-sensitive ovarian cancer.

Evaluation of a Streamlined Oncologist-Led BRCA Mutation Testing and Counseling Model for Patients With Ovarian Cancer.

Purpose There is a growing demand for BRCA1/ 2 mutation ( BRCAm) testing in patients with ovarian cancer; however, the limited number of genetic counselors presents a potential barrier. To facilitate more widespread BRCAm testing in ovarian cancer, pretest counseling by the oncology team could shorten testing turnaround times and ease the pressure on genetic counselors. Patients and Methods The prospective, observational Evaluating a Streamlined Onco-genetic BRCA Testing and Counseling Model Among Patients With Ovarian Cancer (ENGAGE) study evaluated a streamlined, oncologist-led BRCAm testing pathway.

Analysis of Lynch Syndrome Mismatch Repair Genes in Women with Endometrial Cancer.

Objective: Endometrial cancer is the second most frequent neoplasm in women with Lynch syndrome (LS). We sought to assess whether analyzing women with endometrial cancer would identify families with LS not identified with current clinical criteria.

Methods: We included women diagnosed with endometrial cancer younger than 50 years and also older if they had a family cancer history associated with LS.

Factors Associated with the Selection of First-line Bevacizumab plus Chemotherapy and Clinical Response in HER2-negative Metastatic Breast Cancer: ONCOSUR AVALOX Study.

Aim: To evaluate factors associated with the selection of first-line bevacizumab plus chemotherapy and clinical response in HER2-negative metastatic breast cancer (MBC) in clinical practice in Spain.

Patients And Methods: All consecutive adult female patients with HER2-negative MBC who had received first-line bevacizumab plus chemotherapy for at least 3 months were enrolled in the present study.

Results: A total of 292 evaluable patients were included; 25% had triple-negative breast cancer (TNBC) and 75% had hormone receptor-positive breast cancer (HRPBC).

SOLTI NeoPARP: a phase II randomized study of two schedules of iniparib plus paclitaxel versus paclitaxel alone as neoadjuvant therapy in patients with triple-negative breast cancer.

Iniparib is an investigational agent with antitumor activity of controversial mechanism of action. Two previous trials in advanced triple-negative breast cancer (TNBC) in combination with gemcitabine and carboplatin showed some evidence of efficacy that was not confirmed. This phase II randomized neoadjuvant study was designed to explore its activity and tolerability with weekly paclitaxel (PTX) as neoadjuvant treatment in TNBC patients.
