Hypothesis
Does radical mastectomy lead to better clinical outcomes in dogs with malignant mammary tumors compared to conservative treatments?
Conclusion
Radical mastectomy significantly improves survival time and disease-free intervals in dogs with malignant mammary tumors.
Supporting Evidence
- Complete excision of tumors leads to improved survival time.
- Radical mastectomy shows better outcomes than conservative therapy.
- Postoperative complications can be effectively managed.
- Histological margin completeness is a strong prognostic factor.
- Lymphatic invasion is associated with poorer survival outcomes.
- Median survival for complete excision was 992 days.
Takeaway
This study shows that removing all the cancer from dogs' breasts helps them live longer and feel better, even if the cancer has spread.
Methodology
The study involved 95 dogs with mammary tumors who underwent various surgical techniques and were followed for clinical outcomes.
Potential Biases
Potential bias due to the retrospective nature and loss of follow-up for some dogs.
Limitations
The study was retrospective and lacked standardized monitoring and staging, which may affect the reliability of the findings.
Participant Demographics
The cohort consisted of 95 female or spayed female dogs, median age 10 years, with a range of 5 to 18 years.
