Segmental breast resection removes only part of the breast tissue for breast cancer treatment, while mastectomy removes the entire breast. The study compared outcomes of 136 breast cancer patients who underwent either segmental resection (97 patients) or mastectomy (39 patients). Results showed that mastectomy had lower rates of recurrence, metastasis, and mortality compared to segmental resection, especially for patients with stage III cancer. Overall survival rates without recurrence or metastasis were also higher for mastectomy (89.7% and 97.4% respectively) than segmental resection (77.3% and 85.6% respectively). The study concluded that mastectomy resulted in better outcomes than segmental resection for patients in this study population.

Results of breast-conserving
surgery in cancer patient

2. Topicality
Mastectomy-
all of the breast tissue is
removed, sometimes
along with other nearby
tissues and lymphatic
nodes
Segmental resection-
removes a part of the affected
breast (less traumatic, keeps
aesthetic appearance, better
quality of life)
Surgery results

3. Mission
Compare effectiveness of segmental resection versus Madden
mastectomy in breast cancer (BC) women.

9. Conclusions:
• Madden mastectomy, assuming all other conditions equal,
revealed less recurrence, metastasis and mortality.
• While the research got in stage I A-B only the segmental
resection performed the results cannot be statistically
considered.
• Survivals number after Madden mastectomy in the
conditions of this study with no metastasis and recurrence
prove maximum radicalism justified.
