What this trial studies

This observational study at Renji Hospital follows adults with advanced breast cancer who are planned to receive trastuzumab deruxtecan according to current guidelines. Eligible patients are 18 or older with ECOG performance status 0–1 and are followed during routine care for safety, adverse events, and clinical response. Data collected include dosing, treatment duration, laboratory and imaging results, and clinical outcomes without experimental treatment assignments. Pregnant and lactating people are excluded from participation.

Who should consider this trial

Good fit: Adults (≥18) with advanced breast cancer who meet guideline indications for trastuzumab deruxtecan, have ECOG 0–1, and are not pregnant or breastfeeding.

Not a fit: Patients who are pregnant or breastfeeding, have ECOG ≥2, or who are not planned to receive trastuzumab deruxtecan are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, the study could provide real-world safety and effectiveness data to help clinicians refine use of trastuzumab deruxtecan and inform patient care decisions.

How similar studies have performed: Large randomized programs (the DESTINY trials) have demonstrated substantial antitumor activity and clinical benefit for trastuzumab deruxtecan in metastatic HER2‑positive and HER2‑low breast cancer, and this observational work aims to add real‑world confirmation.
