Summary
Clinical stage accurately predicts local spread in prostate cancer (PCa). Higher clinical stage correlates with increased local dissemination and nodular affectation, aiding treatment decisions.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Prostate cancer (PCa) staging is crucial for treatment planning.
- Understanding the correlation between clinical and pathological findings is essential for accurate prognosis.
Purpose of the Study:
- To analyze the relationship between clinical and pathological stages in localized prostate cancer.
- To determine the predictive value of clinical staging for local disease spread.
Main Methods:
- Retrospective analysis of 68 patients with clinically localized prostate cancer.
- Evaluation of data from ilio-obstructive lymphadenectomy and radical prostatectomy.
- Correlation analysis between clinical stage, pre-operative PSA, tumoral grade, and pathological findings.
Main Results:
- Node affectation was found in 23% of patients after lymphadenectomy.
- Capsular invasion or seminal vesicle infiltration occurred in 36% of patients undergoing prostatectomy.
- 41% of patients exhibited local dissemination and/or nodular affectation.
- A direct correlation was observed between clinical stage and local dissemination/nodular affectation.
- Pre-operative PSA and tumoral grade correlated with pathological stage.
Conclusions:
- Clinical stage is a significant predictor of local dissemination and nodular affectation in prostate cancer.
- Pathological findings like lymph node involvement and capsular invasion are common.
- Pre-operative factors like PSA and tumoral grade are associated with pathological stage, informing treatment strategies.
