Palbociclib in Combination with either Aromatase Inhibitors or Fulvestrant for Patients with Advanced HR+/HER2- Breast Cancer in Germany: Final Results of the Phase 2 Multicohort INGE-B Trial.

Introduction: The INGE-B trial (NCT02894398) aimed to confirm the efficacy and safety data from the PALOMA trials for patients treated first line (1L) with palbociclib (PAL) and letrozole or 1L and later line with PAL and fulvestrant. In addition, so far lacking evidence for efficacy and safety on the combination of PAL with anastrozole, exemestane (1L), or letrozole (later line) was investigated.

Methods: The prospective, multicenter, multicohort phase 2 trial INGE-B enrolled adult patients with locally advanced, inoperable, or metastatic HR+/HER2- breast cancer in Germany.

The impact of physical activity on progression-free and overall survival in metastatic breast cancer based on molecular subtype.

Background: Although adequate physical activity has been shown to be beneficial in early breast cancer, evidence in metastatic breast cancer is sparse and contradictory, which could be related to distinct effects of physical activity on the different molecular cancer subtypes. Therefore, we here evaluated the effect of physical activity on progression-free and overall survival (PFS, OS) in metastatic breast cancer, specifically looking at molecular subtypes.

Methods: International Physical Activity Questionnaire (IPAQ) questionnaires, filled out by patients enrolled in the prospective PRAEGNANT registry (NCT02338167; n = 1,270) were used to calculate metabolic equivalent task (MET) minutes, which were subsequently categorized into low (n = 138), moderate (n = 995) or high IPAQ categories (n = 137).

Susceptibility gene mutations in germline and tumors of patients with HER2-negative advanced breast cancer.

Germline mutations in BRCA1 and BRCA2 (gBRCA1/2) are required for a PARP inhibitor therapy in patients with HER2-negative (HER2-) advanced breast cancer (aBC). However, little is known about the prognostic impact of gBRCA1/2 mutations in aBC patients treated with chemotherapy. This study aimed to investigate the frequencies and prognosis of germline and somatic BRCA1/2 mutations in HER2- aBC patients receiving the first chemotherapy in the advanced setting.

CDK4/6 Inhibition - Therapy Sequences and the Quest to Find the Best Biomarkers - an Overview of Current Programs.

In recent years, new targeted therapies have been developed to treat patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancer. Some of these therapies have not just become the new therapy standard but also led to significantly longer overall survival rates. The cyclin-dependent kinase 4 and 6 inhibitors (CDK4/6i) have become the therapeutic standard for first-line therapy.

Attrition in the First Three Therapy Lines in Patients with Advanced Breast Cancer in the German Real-World PRAEGNANT Registry.

With more effective therapies for patients with advanced breast cancer (aBC), therapy sequences are becoming increasingly important. However, some patients might drop out of the treatment sequence due to deterioration of their life status. Since little is known about attrition in the real-world setting, this study assessed attrition in the first three therapy lines using a real-world registry.

Neratinib as Extended Adjuvant Treatment of HER2-Positive/HR-Positive Early Breast Cancer Patients in Germany, Austria, and Switzerland: Interim Results of the Prospective, Observational ELEANOR Study.

Introduction: Prognosis of patients diagnosed with HER2+ early breast cancer (eBC) has substantially improved, but distant recurrences impacting quality of life and survival still occur. One treatment option for extended adjuvant treatment of patients with HER2+/HR+ eBC is neratinib, available in Europe for patients who completed adjuvant trastuzumab-based therapy within 1 year. The ELEANOR study is investigating the real-world use of neratinib in Germany, Austria, and Switzerland.

Efficacy, safety, and prognosis prediction in patients treated with ribociclib in combination with letrozole: Final results of phase 3b RIBECCA study in hormone receptor positive, human epidermal growth factor receptor-2 negative, locally advanced or metastatic breast cancer.

Background: In MONALEESA-2, addition of ribociclib to letrozole resulted in significantly longer progression-free survival (PFS) in postmenopausal women with HR+HER2- advanced breast cancer (ABC). RIBociclib for the treatment of advanCed breast CAncer (RIBECCA) study investigated ribociclib plus letrozole in a patient population reflecting routine clinical practice.

Patients And Methods: In this multicenter, open-label, single-arm, phase 3b study, patients with HR+HER2- ABC not amenable to curative therapy and ECOG performance status ≤ 2 received ribociclib plus letrozole (cohort A: postmenopausal women and men in first-line; cohort B: pre-/perimenopausal women in first-line [B1], patients pretreated for advanced disease [B2]).

Update Breast Cancer 2023 Part 2 - Advanced-Stage Breast Cancer.

In recent years, a number of new therapies have led to advances in the treatment of patients with advanced breast carcinoma. These substances are mainly CDK4/6 inhibitors and other substances that can overcome endocrine resistance, oral selective estrogen receptor degraders, antibody drug conjugates (ADCs), and PARP inhibitors. This review summarizes and evaluates the latest study results that have been published in recent months.

How detection of immune-related adverse events fails during transfer of patients between medical sectors.

Immune-related adverse events (irAEs) induced by immune checkpoint inhibitors (ICIs) in mono- or combination therapy may be acute or delayed, partly arising long after termination of treatment. They may be reversible or persistent. Treatment duration with ICIs is usually one year in the adjuvant setting of solid tumors, and until progression or inacceptable toxicity in metastatic disease.

Significantly longer time to deterioration of quality of life due to CANKADO PRO-React eHealth support in HR+ HER2- metastatic breast cancer patients receiving palbociclib and endocrine therapy: primary outcome analysis of the multicenter randomized AGO-B WSG PreCycle trial.

Background: The multicenter, randomized, phase IV, intergroup AGO-B WSG PreCycle trial (NCT03220178) evaluated the impact of CANKADO-based electronic patient-reported outcome (ePRO) assessment on quality of life (QoL) in hormone receptor-positive, human epidermal growth factor receptor 2-negative locally advanced or metastatic breast cancer (MBC) patients receiving palbociclib and an aromatase inhibitor or palbociclib + fulvestrant. CANKADO PRO-React, a European Union-registered medical device, is an interactive autonomous application reacting to patient self-reported observations.
