Early Recurrence is Common in Triple-Negative Breast Cancer After Chemo-Immunotherapy

In a review of five clinical trials, most recurrences of triple-negative breast cancer after neoadjuvant chemo-immunotherapy occurred within 24 months. This pattern was even more pronounced in patients with residual disease after initial treatment, emphasizing the need for improved strategies to prevent early relapse. The study was limited by its reliance on extracted data from published survival curves and heterogeneity across the included trials.

Possible Conflicts of Interest

Multiple authors disclosed financial ties to pharmaceutical companies involved in cancer treatment, including consulting fees, honoraria, research funding, and advisory board positions.

Identified Weaknesses

Data source limitations

The reliance on extracted data from published Kaplan-Meier curves introduces potential inaccuracies and limits the depth of analysis possible. Individual patient data would allow for more robust investigation.

Heterogeneity across trials

The study includes data from several different trials, each with varying treatment regimens and patient populations, making it difficult to isolate the impact of specific factors on recurrence timing.

Focus on event-free survival

The study primarily focuses on event-free survival, which includes events other than distant recurrence. While these are less common, they could still influence the observed patterns.

Rating Explanation

This study provides valuable insights into the timing of recurrence in a high-risk patient population. The analysis of multiple clinical trials strengthens the findings, but the limitations related to data source and heterogeneity across trials warrant a slightly lower rating than a 5.
