Complete pathological response has been recognised as an important predictor of long-term remission, meaning it is often a key endpoint in clinical trials. Dr Bernardo Rapoport talks to touchONCOLOGY about complete pathological response and which clinical characteristics, such as molecular subtype and Ki-67, are associated with pathological response. Ki-67 is an important prognostic factor, not only in breast cancer but also in neoendocrine tumours, prostate cancer, and brain tumours. Dr Rapoport explains how the expression of Ki-67 translates to cell replication and how it can be an indicator of treatment response.
1. What is the definition of complete pathological response? (0:11)
2. Why has complete pathological response become such an important endpoint in trials of neoadjuvant chemotherapy in early breast cancer? (1:09)
3. What were the most important prognostic factors associated with complete pathological response in your recent study? (2:03)
4. What is the Ki-67 protein and what is its prognostic significance in early breast cancer subtypes? (3:09)
5. What future studies are planned in the investigation of this potential biomarker? (4:30)

Trastuzumab deruxtecan (T-DXd) is approved in the United States and European Union for use in patients with HER2+ unresectable/metastatic breast cancer. Approval was based on the randomized, multicenter, open-label, phase III DESTINY-Breast03 (NCT03529110) trial.

Erika Hamilton, SABCS 2022: Trastuzumab deruxtecan and trastuzumab deruxtecan + pertuzumab in HER2+ metastatic breast cancer
Preclinical findings have suggested that when used in combination with anticancer treatments, trastuzumab deruxtecan (T-Dxd) could improve treatment efficacy in HER2+ metastatic breast cancer (mBC). In this interview we discuss with Dr Erika Hamilton (Sarah Cannon Research Institute, Tennessee Oncology, Nashville, TN) preliminary data from the dose expansion phase of the DESTINY-Breast07 (DB-07) (NCT04538742) trial.

Sudeep Gupta, SABCS 2022: Addition of platinum to neoadjuvant chemotherapy in patients with triple-negative breast cancer: A phase III randomized controlled trial
The impact of adding platinum on long-term outcomes in triple-negative breast cancer (TNBC) has not been definitively established. The controlled, single-centre, phase III study conducted by Tata Memorial Hospital in Mumbai, India evaluated the efficacy and toxicity of adding platinum to standard neoadjuvant chemotherapy in patients with triple-negative breast cancer. In this touchONCOLOGY interview, we speak […]
