Brief Summary

Neoadjuvant radiotherapy(NART) followed by mastectomy and immediate DIEP flap reconstruction is feasible and technically safe. However, reports of NACT followed immediate implant-based breast reconstruction are rare. Some studies have shown that NART followed immediate implant-based breast reconstruction seems feasible and can be safely attempted. It's well known that radiotherapy after implant-based breast reconstruction have negative effects on implant and cosmetic results. So, investigators conducted a polit study to learn about acute post-surgical complications following skin-sparing mastectomy and immediate implant-based breast reconstruction after NART.

Outcome Measures

Primary Outcomes (1)

  • Postoperative complications at 3 months following skin-sparing mastectomy and immediate implant-based breast reconstruction after NART

    Surgical complications are defined as any complication requiring surgical intervention necessary within a period up to three months after the final reconstruction. Including Infection, hematoma , loss of implant or flap, fat necrosis, wound breakdown,defined and scored using the C-DC37.

    3 months following skin-sparing mastectomy and immediate breast reconstruction

Secondary Outcomes (4)

  • Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 .

    Within 3 months after both breast reconstruction and radiotherapy

  • Number of participants with removal of implant.

    6 months after surgery

  • Patient satisfaction.

    3 months and 12 months after surgery

  • Pathological complete response (pCR) assessed in skin-sparing mastectomy specimen

    Within 2 weeks after skin-sparing mastectomy

Study Arms (1)

Neoadjuvant radiotherapy group

EXPERIMENTAL

Radiotherapy followed by skin-sparing mastectomy and immediate implant-based reconstruction in HBCH

Radiation: Neoadjuvant radiotherapy

Interventions

In case of neoadjuvant chemotherapy, RT will start 3-4 weeks after the last course of chemotherapy. A dose of 15 x 2.67 Gy 5 fractions or 16 x 2.67Gy 5 fractions per week. A skin-sparing mastectomy and a immediate implant-based breast reconstruction will be performed, approximately 2-6 weeks after latest radiotherapy treatment.

Neoadjuvant radiotherapy group
