Sir:

Autologous fat grafting is widely used in reconstructive breast surgery but, more recently, is also being used in breast augmentation. For 20 years, the cautious recommendation of the American Society of Plastic and Reconstructive Surgeons was a real obstacle.1 Nevertheless, for a few years, we have witnessed a strong increased confidence in this procedure.

A patient aged 34 years was admitted for two breast nodules. Initially, a tumorectomy had been performed with insufficient exeresis margins. Thus, a mastectomy with axillary node dissection had been performed followed by chemotherapy and radiotherapy. Twenty-four months later, a reconstructive operation was started, the first step of which consisted of autologous fat grafting. At 4 months, during the expander's setting, the mastectomy scar was excised (Fig. 1). Discrete lumps and papular lesions had been noticed. Histologic analysis confirmed local recurrence of the carcinoma. Currently, the patient presents a metastatic invasion of the sternum.

Radiographically, the studies in favor of a slight modification of the parenchyma are numerous, and a trained radiologist finds little difficulty in interpretation. The cancer issue is different. In vitro, the promotion of cancer recurrence and metastases has been demonstrated through the action of the adipose-derived stem cells, the neoangiogenesis, and aromatase.2–5 Nevertheless, these relations have never been highlighted in vivo. This can be explained by the actual rupture between the laboratory studies and those in humans.


We are attempting to authenticate not a real causal link but the possibility of a synchronous recurrence to autologous fat grafting that may have been masked. Nonetheless, the risks of promoting a latent cancer or metastases are not excluded. Moreover, this patient very quickly presented metastases. Histologically, it is interesting to note that the tumor cells were displayed along the trenches created during autologous fat grafting (Fig. 2). It is possible that either the cancer recurrence was already present and the cannula went in the tumor, participating in local dissemination, or the quiescent tumor cells resumed their development along the graft trenches. The extension to the sternum could also result either from the dissemination through the cannula or from the metastatic development of the tumor.

On the international level, the behavior is not homogenous. In 2009, the American Society of Plastic Surgeons Fat Graft Task Force had concluded that no reliable study confirmed the absence of risk of cancer. In 2011, the French Society of Plastic and Reconstructive Surgery, which had strictly advised against breast autologous fat grafting since 2007, changed their position. The French Society is now suggesting autologous fat grafting as part of a clinical protocol. Currently, a prospective study is ongoing in France [Adipose Tissue Transfer for Moderate Breast Cancer Conservative Treatment Sequella (GRATSEC); http://clinicaltrials.gov/show/NCT01035268] in an attempt to provide answers with a high level of evidence regarding the uncertainties between autologous fat grafting and breast neoplasia.2


This case, atypical in its chronology and histology, enables us to raise the questions once more regarding this procedure and of its controversial characteristics on breast cancer. The absence of scientific evidence must lead us to remain vigilant, even nowadays. Information and regular patient follow-up remain essential in the long term with, if possible, a national compulsory registry to centralize the data.
