Summary
This study on surgical oncology found that lymph node status significantly impacts relapse rates in patients under 50. Multicenter collaboration improves outcomes and reduces complications in smaller surgical settings.
Area of Science:
- Oncology
- Surgical Oncology
- Clinical Research
Background:
- Cancer treatment outcomes can vary based on institutional and surgeon experience.
- Standardized treatment protocols are essential for consistent patient care.
- Understanding factors influencing disease recurrence is crucial for improving survival rates.
Purpose of the Study:
- To evaluate the clinical outcomes of surgical oncology patients treated across multiple institutions.
- To identify prognostic factors for disease relapse and survival.
- To assess the impact of multicenter collaboration on patient outcomes.
Main Methods:
- Retrospective analysis of 66 patients operated between 1986-1994 across 11 institutions.
- Data collection included patient demographics, diagnosis, treatment, and follow-up.
- Statistical analysis to determine correlations between clinical factors and outcomes.
Main Results:
- A 5-year disease-free survival of 51% and overall survival of 77% were observed.
- Positive lymph node status (pN(+)) at diagnosis was significantly correlated with relapse (p = 0.024).
- Single women experienced prolonged diagnostic delays (p = 0.025).
- No significant differences in outcomes were found between hospitals or surgeons.
Conclusions:
- Lymph node status is a critical predictor of relapse in surgical oncology.
- Multicenter studies and standardized treatment protocols enhance cure rates and minimize morbidity.
- Collaborative efforts in surgical oncology are vital for optimizing patient care and outcomes.
