Summary
This study analyzed 80 prostate cancer patients, finding advanced stages (D) and poorly differentiated tumors were common. Survival rates varied significantly by stage, highlighting the need for early detection and tailored treatments for prostate cancer.
Area of Science:
- Urology
- Oncology
- Pathology
Context:
- Retrospective analysis of 80 prostate cancer patients from Kyorin University School of Medicine (1976-1986).
- Prostate cancer incidence was 3.9% among male inpatients.
- Patient age ranged from 55-88 years (average 72).
Purpose:
- To analyze the clinical characteristics, treatment modalities, and survival rates of prostate cancer patients.
- To correlate clinical stage, histological grade, and T classification.
- To evaluate treatment outcomes based on different therapeutic approaches.
Summary:
- Common symptoms included dysuria, pollakisuria, and hematuria, with an average diagnostic delay of 22 months.
- Clinical stages were predominantly Stage D (71.3%), with 40.2% poorly differentiated adenocarcinomas.
- Treatment involved antiandrogen therapy (71.25%), radiation (16.25%), surgery (7.5%), and chemotherapy (5%).
Impact:
- Overall 5-year survival rate was 54.4%.
- Stage-specific survival rates showed 100% for Stage A (4 years) and B (5 years), 87.5% for Stage C (5 years), and 40.5% for Stage D (5 years).
- Findings underscore the prognostic significance of clinical stage in prostate cancer outcomes.
