Distress thermometer and determinants of psychological distress in metastatic breast cancer

The single-item DT has been determined to be a valid tool for screening distress in patients with MBC. We recommend using a cut-off score of 4 in this population. While our analysis revealed a significant association between poor treatment response and elevated distress scores, these findings cohere with the broader clinical imperative to prioritise distress management for all cancer patients regardless of treatment outcomes.
