Treating Pain and Fat Necrosis after Breast Cancer Surgery with Fat Grafting: Is one Session Enough?

BACKGROUND

Chronic pain after breast cancer surgery is affecting up to 60% of patients, causing significant morbidity to patients. Lately, fat grafting has been applied as a therapy for chronic neuropathic pain.

METHODS

We report a series of eighteen patients, who were treated for pain after breast cancer surgery. Twelve patients had a breast conserving therapy, two a mastectomy and four an autologous flap-based reconstruction. While most presented with neuropathic pain, six patients had fat necrosis in their history. Most patients presented with severe pain (77%) and were treated with fat grafting sessions, performed by water-assisted liposuction.

RESULTS

All patients responded to the interventions; the median number of fat grafting sessions was 2, the median duration of the interventions was 4 months, and the median follow-up period was 56.5 months. The median pain prior to the fat grafting procedure had an intensity of 8 (range 7-9) numeric rating scale points; after the first intervention, this was reduced to 4 (range 2.3-5.8); and after the second intervention, it was down to 2 (range 0.8-3.3). Patients with pain intensities of 4-5 had a good chance of achieving analgesia after one session.

CONCLUSIONS

Fat grafting could be a new treatment modality for symptomatic fat necrosis: complete or partial suction of the necrosis and/or fat grafting around the necrosis to reduce inflammation and pain. Fat grafting proved a valuable tool, reducing pain or even achieving analgesia after breast cancer surgery presenting with a highly favorable risk-benefit ratio.

Subaxillary Replacement Flap Compared with the Round Block Displacement Technique in Oncoplastic Breast Conserving Surgery: Functional Outcomes of a Feasible One Stage Reconstruction

BACKGROUND

For selected women diagnosed with breast cancer (BC), partial reconstructive techniques involve displacement or replacement procedures to improve cosmesis without compromising oncological safety. This study aims to evaluate the surgical outcomes of the round block (RB) compared with the subaxillary flap (SF) technique for patients with upper outer tumor.

PATIENTS AND METHODS

Thirty-three patients treated with oncoplastic conserving surgery (15 RB and 18 SF) were enrolled in this retrospective study. After carrying out a comparison of baseline characteristics, all cases were recruited for postoperative evaluation of oncological and cosmetic parameters. Moreover, we investigated several scoring combinations to check whether they could discriminate surgeon and patient satisfaction according to different functional results.

RESULTS

Median age (p < 0.05), average tumor size (p > 0.05), estimated resection volume (p > 0.05), and nodal involvement (p > 0.05) were slightly higher in the SF group. A greater frequency of DCIS (p < 0.05) in the RB series correlated with reintervention for positive margins (p > 0.001). At a mean follow-up of 19 months, no locoregional recurrences were recorded and early and late complications were comparable (p > 0.05). The overall satisfaction with cosmesis was characterized by similar proportions of good results (p > 0.05), with some details more related to each procedure.

CONCLUSION

The proposed techniques represent effective solutions for reshaping that follows upper outer wide excision, achieving comparable complication rates, low reinterventions, and good aesthetic results in relation to technical and social functioning evaluations. However, it is crucial to establish a careful patient selection in order to manage correct surgical planning while predicting any potential sequelae or complication.

Dual-Layer Rotation: A Versatile Therapeutic Mammoplasty Technique

Background

Multifocal or complex breast lesions are a challenge for breast-conserving surgery, particularly surgery in small breasts or those located in the upper inner quadrant. The dual-layer rotation technique exploits the idea of manipulating the skin and glandular tissue in separate layers to fill the resection cavity via vertical mammoplasty if skin excision is not required, except in the central area.

Methods

The authors performed a retrospective review of consecutive breast cancer patients who underwent DLR mammoplasty between 2017 and 2019 at a single institution. Clinical data, reoperations, surgical complications, delays in adjuvant treatments, and the need for late revisional surgery were evaluated. Aesthetic outcomes were evaluated objectively and subjectively from photographs.

Results

The study included 46 breasts of 40 patients. Tumors were located in the UIQ (30%, 14/46) or in multiple quadrants (22%, 10/46). One third (33%, 13/40) of the patients had a small breast cup size (A–B). Negative margins were primarily achieved in 45 of the 46 breasts. Major complications occurred in three patients, who needed reoperation, and adjuvant therapy was delayed for one of these patients. Late refinement surgery was needed for two patients. The objective and subjective aesthetic outcomes were good or excellent regardless of the tumor position.

Conclusion

As a novel oncoplastic approach, DLR mammoplasty offers a one-step procedure to treat selected breast cancer patients with challenging resection defects due to different breast sizes or lesion locations. The technique preserves the breast’s natural appearance.

Update on oncoplastic techniques in breast conserving surgery: algorithms for predictable results and custom-made reconstructions

Breast cancer surgery is going to be a relevant specialty involved in the multidisciplinary disease management, finalized to guarantee high performances on mortality reduction together with a quality of life improvement. The intellectual architecture of this field is characterized by its inclination to respect, sharing, empathy and scientific knowledge that can make it a high model of medical culture. In this context, oncoplastic breast conserving surgery is identified by special aesthetic sensitivities, as well as creativity and innovation. Knowing how to reshape the gland and fill the gaps, planning the targeted exeresis design, while anticipating the final outcome, respecting symmetries and ensuring first of all oncological safety, are the new skills that are required to the breast surgeon. Several tecniques could provide a refined surgical treatment but always challenging according to anatomical findings and patient expectations, as a systematic process of self-critical reflection, with the purpose to optimize criteria for improving therapeutic results.

Clinical Significance of Oncoplastic Breast-Conserving Surgery and Application of Volume-Displacement Technique

ABSTRACT

Oncoplastic breast-conserving surgery for breast cancer has been continuously developing in recent years, and it has become an important part of breast cancer surgery. Its safety and aesthetics have been widely recognized by domestic and foreign experts. However, due to the complexity and diversity of individuals and diseases, and the need for integrating the thinking of breast surgery and plastic surgery, it is still a challenge for breast surgeons. This review summarizes the pros and cons of its clinical application through a comprehensive discussion of hot issues in oncoplastic breast-conserving surgery and introduces common volume-displacement techniques in the clinic for reference by doctors in daily work.
