Summary
This summary is machine-generated.Elevated prostate-specific antigen (PSA) and Gleason scores increase cardiovascular death (CVD) risk in prostate cancer (PC) patients post-radiotherapy (RT) or chemotherapy (CT). These PC patients need closer CVD monitoring.
Area Of Science
- Oncology
- Cardiology
- Medical Statistics
Background
- Tumor characteristics impact cardiovascular death (CVD) risk in cancer patients.
- The influence of prostate cancer (PC) tumor characteristics on CVD risk after radiotherapy (RT) or chemotherapy (CT) is understudied.
- This study investigates PC tumor characteristics and CVD risk in patients treated with RT or CT.
Purpose Of The Study
- To explore the association between PC tumor characteristics and CVD risk.
- To identify specific tumor markers predicting CVD risk in PC patients undergoing RT or CT.
- To develop a predictive model for CVD risk stratification.
Main Methods
- Fine-gray competitive risk analysis for CVD risk factor identification.
- Sensitivity analyses to adjust for confounding variables.
- Nomogram development and validation using calibration curves and concordance indexes (C-indexes) for predicted prostate-specific antigen (PSA) and Gleason scores.
Main Results
- A total of 120,908 patients were analyzed with an 80-month follow-up.
- PSA values ≥10 ng/mL (adjusted HR: 1.28-1.27) and Gleason score >7 (adjusted HR: 1.23) were significant CVD risk factors post-RT/CT.
- The nomogram demonstrated good predictive performance with C-indexes of 0.66 (training) and 0.67 (validation).
Conclusions
- Elevated PSA (≥10 ng/mL) and Gleason scores (>7) are associated with increased CVD risk in PC patients post-RT or CT.
- These findings suggest a need for enhanced long-term CVD risk monitoring in these patients.
- The developed nomogram can aid in stratifying CVD risk for personalized patient management.

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
