Background: Individual risk prediction of 5-year locoregional recurrence (LRR) and contralateral breast cancer (CBC) supports decisions regarding personalised surveillance. The previously developed INFLUENCE tool was rebuild, including a recent population and patients who received neoadjuvant systemic therapy (NST).

Methods: Women, surgically treated for nonmetastatic breast cancer, diagnosed between 2012 and 2016, were selected from the Netherlands Cancer Registry.

Article Synopsis
  • This study focuses on understanding and predicting clinically relevant fatigue (CRF) in cancer patients two to three years after diagnosis, aiming to enhance supportive care for clinicians.
  • Researchers examined data from 3160 patients with various cancer types, using both traditional logistic regression and advanced machine learning models to identify factors associated with CRF.
  • While the logistic regression model showed good discrimination between patients with and without CRF, it also indicated potential underdiagnosis, raising concerns about the clinical applicability of the models used.

Background: A previous prospective multicenter study revealed the change of the oncologists' chemotherapy advice due to the 70-Gene signature (GS) test result in half of the estrogen receptor-positive (ER+) invasive early-stage breast cancer patients with disputable chemotherapy indication. This resulted in less patients receiving chemotherapy. This study aims to complement these results by the 7-year oncological outcomes according to the 70-GS test result and the oncologists' pre-test advice.

Unlabelled: The current project is part of the Spatial location of breast cancer local rECurRence aftEr masTectomy (SECRET) study (NCT06130111). Herein we compared the chest wall thickness after non-skin sparing mastectomy (non-SSM) with the chest wall thickness after SSM, as a surrogate for residual breast tissue after mastectomy.

Methods: The study was approved by the ethics committee of relevant institutions.
