Multi-modal image analysis using deep learning (DL) lays the foundation for neoadjuvant treatment (NAT) response monitoring. However, existing methods prioritize extracting multi-modal features to enhance predictive performance, with limited consideration on real-world clinical applicability, particularly in longitudinal NAT scenarios with multi-modal data. Here, we propose the Multi-modal Response Prediction (MRP) system, designed to mimic real-world physician assessments of NAT responses in breast cancer.

Article Synopsis
  • Organ preservation through the Watch and Wait (WW) approach in rectal cancer patients shows promise but poses a risk of local regrowth (LR), leading to higher rates of distant metastases (DM) compared to traditional surgery (TME).
  • A study comparing 508 LR patients managed by WW and 893 near-complete pathologic response (nPCR) patients after TME found a significantly higher DM rate in the LR group (22.8% vs. 10.2%).
  • The research concluded that patients with LR have poorer 3-year DM-free survival (75% vs. 87%) and highlight that leaving a primary undetectable tumor can result in worse overall outcomes.

Eur J Cancer

November 2024

Department of Obstetrics and Gynaecology, GROW school for oncology and developmental biology, Maastricht University Medical Centre+, Maastricht, the Netherlands; Department of Obstetrics and Gynaecology, Catharina Hospital, Eindhoven, the Netherlands.

Article Synopsis
  • In the FIGO 2018 classification, women with early-stage cervical cancer are now classified differently based on their tumor's size and spread, which could change how they are treated.
  • A study looked at a group of 992 women with specific types of cervical cancer to see how often the cancer spread to lymph nodes (pN+) and found that certain factors like lymphovascular space invasion (LVSI) increased the risk of spread.
  • The results suggest that women with LVSI-positive tumors should have lymph node checks, but those with LVSI-negative tumors may not need this if their tumor size and other factors are considered.
