The Effect of Adjuvant Radiotherapy on One- and Two-Stage Prosthetic Breast Reconstruction and on Autologous Reconstruction: A Multicenter Italian Study among 18 Senonetwork Breast Centres

Purpose

In modern breast cancer treatment, a growing role has been observed for breast reconstruction together with an increase in clinical indications for postmastectomy radiotherapy (PMRT). Choosing the optimum type of reconstructive technique is a clinical challenge. We therefore conducted a national multicenter study to analyze the impact of PMRT on breast reconstruction.

Methods

We conducted a retrospective case-control multicenter study on women undergoing breast reconstruction. Data were collected from 18 Italian Breast Centres and stored in a cumulative database which included the following: autologous reconstruction, direct-to-implant (DTI), and tissue expander/immediate (TE/I). For all patients, we described complications and surgical endpoints to complications such as reconstruction failure, explant, change in type of reconstruction, and reintervention.

Results

From 2001 to April 2020, 3116 patients were evaluated. The risk for any complication was significantly increased in patients receiving PMRT (aOR, 1.73; 95% CI, 1.33-2.24; p < 0.001). PMRT was associated with a significant increase in the risk of capsular contracture in the DTI and TE/I groups (aOR, 2.24; 95% CI, 1.57-3.20; p < 0.001). Comparing type of procedures, the risk of failure (aOR, 1.82; 95% CI, 1.06-3.12, p=0.030), explant (aOR, 3.34; 95% CI, 3.85-7.83, p < 0.001), and severe complications (aOR, 2.54; 95% CI, 1.88-3.43, p < 0.001) were significantly higher in the group undergoing DTI reconstruction as compared to TE/I reconstruction.

Conclusion

Our study confirms that autologous reconstruction is the procedure least impacted by PMRT, while DTI appears to be the most impacted by PMRT, when compared with TE/I which shows a lower rate of explant and reconstruction failure. The trial is registered with NCT04783818, and the date of registration is 1 March, 2021, retrospectively registered.

Safety of autologous fat grafting in breast cancer: a multicenter Italian study among 17 senonetwork breast units autologous fat grafting safety: a multicenter Italian retrospective study

BACKGROUND

Autologous fat grafting (AFG), defined as the re-implant to the breast of fat tissue from different body areas, has been firstly applied to esthetic plastic surgery and then has moved to reconstructive surgery, mainly used for scar correction and opposite breast altering. Nevertheless, due to the potentially unsafe stem-like properties of adipocytes at the tumoral bed level, no clear evidence of the procedure's oncological safety has been clearly documented at present.

PATIENTS AND METHODS

We retrospectively collected data of early breast cancer (BC) patients from 17 Italian Breast Units and assessed differences in terms of locoregional recurrence rate (LRR) and locoregional recurrence-free survival (LRFS) between patients who underwent AFG and patients who did not. Differences were analyzed in the entire cohort of invasive tumors and in different subgroups, according to prognostic biological subtypes.

RESULTS

With a median follow-up time of 60 months, LRR was 5.3% (n = 71) in the matched population, 3.9% (n = 18) in the AFG group, and 6.1% (n = 53) in the non-AFG group, suggesting non-inferiority of AFG (p = 0.084). Building Kaplan-Meier curves confirmed non-inferiority of the AFG procedure for LRFS (aHR 0.73, 95% CI 0.41-1.30, p = 0.291). The same effect, in terms of LRFS, was also documented among different biological subtypes (luminal-like group, aHR 0.76, 95% CI 0.34-1.68, p = 0.493; HER2 enriched-like, aHR 0.89, 95% CI 0.19-4.22, p = 0.882; and TNBC, aHR 0.61, 95% CI 0.12-2.98, p = 0.543).

CONCLUSIONS

Our study confirms in a very large, multicenter cohort of early BC patients that, aside the well-known benefits on the esthetic result, AFG do not interfere negatively with cancer prognosis.

Extended Hueston Flap: New Solution for Primary Closure

Thumb tip injuries are very common in hand trauma, and several flaps are available to restore the defect. One of them is the Hueston flap. It is very simple and quick to harvest, but it could lead to donor site problems. The variant "radial extended" of this flap, proposed in this article, allows a primary closure of donor site avoiding making scar on contact areas subject to frequent use. We performed this technique in a clinical case that presented a distal thumb amputation with good aesthetic result and satisfactory function.

Conservative mastectomy versus nipple-sparing mastectomy: preliminary considerations of oncological safety on 30 patients not receiving intra-operative radiotherapy

Background

For several years, there has been broad consensus that nipple-sparing mastectomy is a safe surgical treatment for breast cancer. However, the technique is associated with a relatively high risk of local recurrence (LR) behind the nipple-areola complex (NAC). It is for this reason that some years ago we introduced intraoperative radiotherapy with electrons (ELIOT) targeted specifically to the NAC to reduce the probability of recurrence there. However, in some cases we preferred to avoid ELIOT when the NAC appears to have a poor blood supply to ensuring the best chance of NAC survival.

Methods

From July 2003 to April 2010 at our institute, 30 patients received nipple-sparing mastectomy but neither ELIOT nor external radiotherapy, as the surgeon considered the irradiation would markedly compromise the chances of NAC survival, because of sub-optimal vascularization.

Results

After a median follow-up of 5 years there were no LRs with minor post-operative complications.

Conclusions

This preliminary case series indicates that the presented technique can be a safe procedure in breast cancer surgery, but requires greater number of cases and a longer follow-up to confirm the oncological safety.

Critical Upper Limb Ischemia Due to Brachial Tourniquet in Misdiagnosed Thoracic Outlet Syndrome after Carpal Tunnel Decompression: A Case Report

We present the case of a 68-year-old woman, referred to our department for critical upper limb ischemia, which had occurred a few days after homolateral surgical ligamentotomy for carpal tunnel syndrome, diagnosed and confirmed by electromyography, and performed with a brachial tourniquet. The patient was later admitted for subsequent progressive necrosis of the first three fingers of the left hand, accompanied by signs of upper limb ischemia. An accessory cervical rib was identified, completely obliterating the subclavian artery distally at the origin of the suprascapular artery. A complete humeral artery occlusion was also found at the middle third of the humerus. The accessory rib was resected and the subclavian artery recanalized. A few days later, necrosis of the distal third of the first two fingers appeared and surgical resection was performed. Despite this chronic condition, the acute occlusion of collateral circles was probably induced by the brachial tourniquet. This represents a rare event, never previously reported in the literature: a case of critical upper limb ischemia due to a brachial tourniquet in a patient with misdiagnosed thoracic outlet syndrome. Until specific electrophysiological criteria for this syndrome can be found, attention should focus on history and clinical examination in patients with suspected carpal tunnel syndrome.

Fournier's Gangrene and Negative Pressure Wound Therapy: A Case Report

INTRODUCTION

Fournier's gangrene is a rare disease that affects the genital, abdominal, and perineal regions and leads to death if not treated promptly.

CASE REPORT

A 42-year-old, obese woman presented to the authors' department affected by Fournier's gangrene. In order to treat her abdominal and genital regions, the authors performed a surgical debridement followed by combined therapy with antibiotics and topical negative pressure wound therapy (NPWT) with instillation plus saline solution.

RESULTS

The combined therapy, but most of all the application of the NPWT, cleaned and decontaminated the wounds. As a direct result of this decontamination, after 20 days, the patient was able to undergo surgery; after 40 days of follow-up, there was no sign of recurrence.

CONCLUSION

Negative pressure wound therapy can be a good and useful treatment in the therapy of serious diseases and for the wound bed preparation in advance of surgery.

Reconstructive strategies for dermatofibrosarcomas of the face: role of regenerative dermal templates

BACKGROUND

Dermatofibrosarcomas protuberans is a challenging cutaneous tumor from an oncologic and reconstructive surgical point of view. Involvement of functionally and aesthetically sensitive areas, such as facial units, in young patients accounts for more demanding cases. An updated evaluation of most beneficial excisional/reconstructive strategies in these cases is still lacking.

METHODS

We investigated the potential of regenerative dermal templates in staged postoncologic reconstructive management of a young woman affected by a dermatofibrosarcomas protuberans of the forehead involving the frontal bone.

RESULTS

Final result was optimal in terms of cosmetic and functional recovery, obtaining a pliability, softness, and color similar to surrounding healthy skin.

CONCLUSION

In facial dermatofibrosarcomas protuberans, staged reconstruction with regenerative dermal templates provides a conservative yet safe and effective management, achieving optimal aesthetic outcomes. We suggest its adoption as first-line treatment in facial dermatofibrosarcomas protuberans that cannot be repaired by direct suture and in equivalent benign yet challenging cases.
