Background: Patients with stage II-III HER2-positive breast cancer have good outcomes with the combination of neoadjuvant chemotherapy and HER2-targeted agents. Although increasing the number of chemotherapy cycles improves pathological complete response rates, early complete responses are common. We investigated whether the duration of chemotherapy could be tailored on the basis of radiological response.

Article Synopsis
  • * A study of 9 patients post-RYGB showed that most did not achieve therapeutic levels of the antihormonal drug tamoxifen at the standard dosage, leading to a recommendation for a higher starting dose in some cases.
  • * Patients with altered CYP2D6 metabolism may need to switch to different treatments, and while no dose adjustments were necessary for other drugs like anastrozole and letrozole, ongoing monitoring for effectiveness is still advised.

Article Synopsis
  • The study investigates real-world treatment strategies for neutropenia in patients taking palbociclib, focusing on their impact on progression-free survival (PFS) against outcomes in clinical trials.
  • Data from 229 patients with HR-positive, HER2-negative metastatic breast cancer were analyzed, revealing different treatment modifications compared to the PALOMA-3 clinical trial, but no significant effect on PFS.
  • Patients deemed ineligible for the PALOMA-3 trial had shorter PFS, emphasizing that real-world outcomes may differ from those observed in clinical trials.

Purpose: CompLEEment-1 (NCT02941926) is a single-arm, open-label, multicentre phase IIIb study investigating the safety and efficacy of ribociclib plus letrozole (RIB + LET) in a large, diverse cohort who have not received prior endocrine therapy (ET) for advanced disease. We present an exploratory analysis of male patients.

Methods: Eligible patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC), who had no prior ET and ≤ 1 line of prior chemotherapy for advanced disease, received RIB + LET.

What Is Known And Objective: Trastuzumab-emtansine is an antibody-drug conjugate developed to decrease off-target toxicity. According to the product label, reactions secondary to extravasation are mild or moderate.

Case Summary: We report on a 51-year-old woman who developed epidermal necrosis after extravasation of trastuzumab-emtansine, which required surgical intervention.

Objective: The aim of this study was to assess the real-world effectiveness and tolerability of palbociclib combined with endocrine therapy for the treatment of hormone receptor positive (HR-positive), human epidermal growth factor receptor 2 negative (HER2-negative), advanced/metastatic breast cancer that progressed on previous endocrine therapy, and to compare these results with the outcomes of the PALOMA-3 clinical trial.

Methods: This study was a retrospective observational cohort study including all patients who started with palbociclib in the St. Antonius Hospital between September 1, 2016 and April 1, 2018 for the treatment of HR-positive, HER2-negative advanced/metastatic breast cancer that progressed on previous endocrine therapy.

Risk stratification of patients with PE has gained interest in terms of the identification of patients in whom treatment on an outpatient base can be considered. Previous studies are of limited value due to their focus on adverse clinical events within several months after diagnosis of PE. We developed a prognostic model, based on easily accessible, clinical, and laboratory parameters, to predict adverse events during the first 10 days after the diagnosis of acute PE.

Introduction: Traditionally, patients with pulmonary embolism (PE) are treated in-hospital until they reach an adequate international normalized ratio (INR). Analogous to patients with a deep venous thrombosis, therapy with low-molecular-weight heparin facilitates out of hospital treatment of PE. We retrospectively analysed the current practice of early anticoagulant therapy in 86 acute PE patients with emphasis on the occurrence and safety of outpatient treatment.

To enable outpatient treatment of a selected group of patients with pulmonary embolism (PE), insight in the determinants of adverse clinical outcome is warranted. We have identified risk factors for serious adverse events (SAE) within the first 10 days of acute PE. We have retrospectively analysed data of 440 consecutive patients with acute PE.

Despite the use of a clinical score and D-dimers to exclude deep vein thrombosis (DVT), the majority of patients still need repeated ultrasound (US). The aim of the study was to investigate whether fibrin monomers (FMs), as markers of thrombin generation, have additional value in the diagnosis of DVT. This is a posthoc analysis of 464 outpatients, participants in a management study using D-dimers (Tina-Quant and a clinical score in the exclusion of DVT.
