NCT05603078

Brief Summary

This study explores the feasibility of preoperative single-dose tumor-bed boost followed by oncoplastic breast-conserving surgery and ultra-hypofractionated postoperative radiotherapy in patients with early stage breast cancer. Patients less than 55 years old, who are diagnosed with breast cancer and are eligible to recieve breast-conserving surgery are enrolled. Patients who are older than 55 years, with suspected regional lymph node metastasis are excluded. The primary end point are the acute toxicities within 4 weeks after adjuvant radiation. The secondary endpoints are oncologic outcomes, surgical complications within 30 days, late toxicities, patients' quality of life and cosmetic outcomes.

Outcome Measures

Primary Outcomes (1)

  • The rate of patients who develop radiation-associated acute toxicity (≥ 2 degree)

    We will record the incidence of ≥ 2 degree radiation-associated acute toxicity, such as breast or chest wall oedema, acute dermatitis, breast pain,itch of breast skin. The incidence of all the above is the primary outcome.

    until 4 weeks of postoperative radiotherapy

Secondary Outcomes (9)

  • Local recurrence rate

    Until 5 years after diagnosis.

  • Local regional recurrence rate

    Until 5 years after diagnosis.

  • Disease-free survival

    Until 5 years after diagnosis.

  • Overall survival

    Until 5 years after diagnosis.

  • Complications of surgery in the short term.

    Until 30 days after the surgery.

  • +4 more secondary outcomes

Study Arms (1)

preoperative tumor-bed boost

EXPERIMENTAL

The participants receive preoperative tumor-bed boost, oncoplastic surgery and adjuvant WBRT±RNI.

Radiation: Preoperative MRI-guided tumor-bed boost and postopreative ultra-hypofractionated radiotherapy (26 Gy/5.2Gy/5)

Interventions

Preoperative tumor-bed boost was performed under MRI Linac, and a single dose of 10Gy is prescribed. The postoperative radiotherapy of 26Gy/5.2Gy/5 fractions is within 6 weeks following surgery. Adjuvant chemotherapy, targeted therapy and endocrine therapy are initiated no more than 12 weeks after surgery.

Fasting blood glucose ≥ 10mmol/L, 2 hours postprandial blood glucose ≥ 13 mmol/L. Poorly controlled psychosis develops or worsens within six months; Active infection; Positive for antibodies to HIV).
