Summary
The round block technique for breast cancer surgery offers comparable operative parameters to standard wide local excision (sWLE). This oncoplastic approach provides better cosmetic outcomes and lower re-excision rates, suggesting potential advantages in selected cases.
Area of Science:
- Oncoplastic breast surgery
- Surgical oncology
- Breast cancer treatment
Background:
- Oncoplastic surgery aims for better tumor resection and lower re-excision rates than standard wide local excision (sWLE).
- Criticisms of oncoplastic surgery include longer scars, increased operating time, and higher complication risks.
- The round block technique is suitable for smaller breasts with minimal ptosis.
Purpose of the Study:
- To compare the operative parameters of the round block technique with sWLE.
- To evaluate cosmesis and re-excision rates between the two surgical methods.
Main Methods:
- A retrospective matched-cohort study comparing breast cancer patients who underwent round block procedures versus sWLE.
- Patients were matched one-to-one based on axillary procedure type.
- Operative parameters, complications, cosmesis, and recurrence rates were compared.
Main Results:
- No significant differences in operating time or length of stay were found between the round block and sWLE groups.
- The round block technique demonstrated superior cosmetic outcomes and lower re-excision rates.
- A higher recurrence rate was observed in the sWLE group, with no complications reported in either group.
Conclusions:
- The round block technique is comparable to sWLE in terms of operative parameters and complication rates.
- Round block technique offers advantages in cosmesis and re-excision rates.
- Round block technique may be a preferred option for selected breast cancer patients.
