Abstract
Breast-conserving treatment (BCT) has become the standard treatment in early-stage breast cancer, Its goal is to provide a treatment as effective as mastectomy, with the added benefit of a preserved breast. However, it is sometimes difficult to achieve good cosmetic results, particularly in patients with large, ill-defined, or poorly situated tumors, for which clear margins are difficult to achieve without leaving deformed and asymmetrical breasts.
Oncoplastic breast conserving surgery (oBCS), which combines a plastic surgical procedure with BCT, is a new surgical approach that extends the role of BCS in situations previously considered unsuitable for conservation (large tumour size, central and lower pole tumour location or multifocality), and allows wide excisions as well as has the potential to improve the aesthetic outcome of BCS and prevents breast deformities by immediate reconstruction of large resection defects.
The quadrantectomy approach or the segmental parenchymal wide excision including the overlying skin were the basis for OP. Plastic surgery techniques were transposed into BCS as a refinement in 1980s in France by Jean-Yves Petit (Institut Goustave-Roussy), Jean-Yves Bobin (Centre Le´on-Be´ rard) and Michel Abbes (Centre Lacassagne).
In our study we compared between Round block technique and Reduction mammoplasty in treatment of early breast cancer, we found that there is no significant difference between the 2 groups as regard the age of the patients , the family history ,comorbidities, side of the tumor, site of the tumor and histopathological result.
And there is significant difference between the 2 groups as regard the Intra-operative time, intra-operative blood loss, contralateral surgery, hospital stay, total drainage volume, drainage days, postoperative complications and cosmetic outcome.
Reduction mammoplasty needs longer operation time, more intra- operative blood loss,needs contralateral surgery for symmetrization.
And regarding the postoperative findings we found that the total drainage volume was more in Reduction mammoplasty than Round block technique, hospital stay was longer in Reduction mammoplasty than Round block technique
As regard postoperative complications we found that there was more complications in Reduction mammoplasty than Round block technique as wound dehiscence and flap necrosis.
As regard cosmetic outcome we found that the cosmetic outcome in Round block technique was better than in Reduction mammoplasty regarding patient’s and surgeon’s satisfaction.
In conclusion, patients with early breast cancer with medium size breast with no major ptosis are candidate for either Round block technique or reduction mammoplasty, round block technique is better for them as there is less morbidity, less complications so no delay in
radiotherapy, better cosmesis, mostly doesn‟t need contralateral breast
surgery for Symmetrization and Reduction mammoplasty needs more surgeon’s experience.
