Hypothesis
Does postoperative radiation reduce the risk of local relapse in low risk breast cancer patients after conservative surgery?
Conclusion
Radiotherapy decreases the risk of local relapse even in low risk patients after conservative breast surgery.
Supporting Evidence
- The study found an 18% local relapse rate in the very low risk group when radiotherapy was omitted.
- Seven patients in the radiation group and two in the non-radiation group experienced distant recurrences.
Takeaway
Giving radiation after breast surgery helps prevent the cancer from coming back, even in patients who are at low risk.
Potential Biases
The breast preservation rate was not predetermined, which may reduce bias in the study design.
Limitations
The study did not formally assess cosmetic outcomes and relied on subjective opinions.
Participant Demographics
Very low risk subgroup of breast cancer patients.
