Therapeutic reduction mammoplasty in large-breasted women with cancer using superior and superomedial pedicles

Outcome reporting in therapeutic mammaplasty: a systematic review

BACKGROUND

Therapeutic mammaplasty (TM) is an oncological procedure which combines tumour resection with breast reduction and mastopexy techniques. Previous systematic reviews have demonstrated the oncological safety of TM but reporting of critically important outcomes, such as quality of life, aesthetic and functional outcomes, are limited, piecemeal or inconsistent. This systematic review aimed to identify all outcomes reported in clinical studies of TM to facilitate development of a core outcome set.

METHODS

Medline, EMBASE, CINAHL and Web of Science were searched from inception to 5 August 2020. Included studies reported clinical outcomes following TM for adult women. Two authors screened articles independently for eligibility. Data were extracted regarding the outcome definition and classification type (for example, oncological, quality of life, etc.), time of outcome reporting and measurement tools.

RESULTS

Of 5709 de-duplicated records, 148 were included in the narrative synthesis. The majority of studies (n = 102, 68.9 per cent) reported measures of survival and/or recurrence; approximately three-quarters (n = 75, 73.5 per cent) had less than 5 years follow-up. Aesthetic outcome was reported in half of studies (n = 75, 50.7 per cent) using mainly subjective, non-validated measurement tools. The time point at which aesthetic assessment was conducted was highly variable, and only defined in 48 (64.0 per cent) studies and none included a preoperative baseline for comparison. Few studies reported quality of life (n = 30, 20.3 per cent), functional outcomes (n = 5, 3.4 per cent) or resource use (n = 28, 18.9 per cent).

CONCLUSION

Given the oncological equivalence of TM and mastectomy, treatment decisions are often driven by aesthetic and functional outcomes, which are infrequently and inconsistently reported with non-validated measurement tools.

Is Autologous Fat Grafting an Oncologically Safe Procedure following Breast Conserving Surgery for Breast Cancer? A Comprehensive Review

BACKGROUND

Autologous fat grafting (AFG) is a recognized surgical procedure to correct deformities following breast conservation surgery (BCS) for breast cancer. However, there are concerns about the oncological safety of this technique. In this study we have reviewed the current literature to assess whether AFG adversely influences the oncological outcome after BCS for breast cancer.

METHODS

We have searched the medical literature using the Embase and PubMed search engines from conception until May 2019 to identify all relevant studies of patients who underwent AFG after BCS. Meta-analysis and meta-regression methodologies were used to calculate the overall relative risk (RR) of loco-regional recurrence (LRR) rates for case-control and case series studies (with historical controls) respectively.

RESULTS

We have identified 26 eligible studies with a total of 1640 patients who had undergone fat transfer after lumpectomy for breast cancer. The meta-analysis of 11 studies revealed an overall RR for LRR of 0.82 [95% confidence interval (CI):0.14-1.66]. The meta-regression of case series revealed an overall incidence of LRR of 1.85% compared with 2.53% for historical controls.

CONCLUSIONS

Our study lends further support to the notion that fat transfer after lumpectomy for breast cancer does not seem to increase the risk of LRR. However further prospective research is required in order to confirm this.

Safety and esthetic outcomes of therapeutic mammoplasty using medial pedicle for early breast cancer

Background

Although therapeutic mammoplasty (TM) was introduced for treatment of localized ductal carcinoma in situ and invasive breast carcinoma (stages I and II) in females with large breast size, the suitability of medial pedicle TM for treatment of breast tumors at different locations has not been established. The objective of this study was to assess the safety and esthetic outcome of medial pedicle TM for breast tumors at different locations.

Methods

The study was conducted from February 2012 to July 2014. Consecutive patients with early breast carcinoma with medium- and large-sized breasts, with or without ptosis, who were offered medial pedicle TM were included in the study. Patients who were not candidates for breast-conserving surgery or those with tumors located along the medial pedicle were excluded. All patients received immediate postoperative adjuvant chemoradiotherapy.

Results

Thirty patients with a mean age of 48.5 years received medial pedicle TM in the breast harboring the tumor or, additionally, the other breast (N=14). The tumors were in the upper (60.0%), lower (26.7%), and lateral (13.3%) quadrants. Minor complications occurred in five cases (5/30, 16.7%) in the ipsilateral and in two (2/14, 14.3%) contralateral breasts. No wound dehiscence or areolar necrosis was recorded. A total of 22 (73.3%) patients were scored as excellent cosmesis. After a median follow-up of 20 months, no locoregional recurrence or distant metastases were observed.

Conclusion

TM using a medial pedicle is a safe and appealing technique among women with tumors at different locations.
