Examining serum TK1 levels to predict breast cancer treatment outcomes

Establishment of Serum TK1 Combined With MRI to Predict Pathological Remission of Breast Cancer With Neoadjuvant Chemotherapy

Observational Yunnan Cancer Hospital · NCT06509555

This study is testing if measuring a specific protein in the blood can help predict how well breast cancer patients will respond to their chemotherapy treatment.

What this trial studies

This observational study investigates the correlation between serum thymidine kinase 1 (sTK1) levels and pathological remission in breast cancer patients undergoing neoadjuvant chemotherapy. Female patients diagnosed with breast cancer will have their clinical and pathological data collected and analyzed to determine the predictive value of sTK1 levels for treatment outcomes. The study employs statistical methods, including logistic regression and ROC curve analysis, to develop and validate a prediction model for pathological complete response (pCR) based on sTK1 and other clinical factors.

Who should consider this trial

Good fit: Ideal candidates are female patients diagnosed with breast cancer who are receiving neoadjuvant chemotherapy and have complete pathological data.

Not a fit: Patients with distant metastasis at diagnosis or those with other primary malignant tumors may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable biomarker for predicting treatment response in breast cancer patients, potentially leading to more personalized treatment strategies.

How similar studies have performed: While the approach of using serum biomarkers for treatment prediction is established, the specific focus on sTK1 in this context is relatively novel and untested.
