Study Overview
Brief Summary
Breast tumors, particularly breast cancer, are increasingly prevalent in China, with a noticeable trend towards younger ages. Preliminary research indicates that Type III Collagen (COL3) plays a crucial role in tissue and organ protection within the tumor microenvironment and can inhibit tumor progression through microenvironmental remodeling. However, there are no clinical studies related to COL3 in breast tumors. This project aims to initiate a multicenter, prospective, randomized, open-label, parallel-controlled trial by locally administering recombinant humanized Type III Collagen (rhCOL3) to patients undergoing breast tumor surgery. The study will observe the incidence of perioperative complications after rhCOL3 injection, as well as changes in aesthetic outcomes and tumor-related pathological indicators following breast tumor surgery with local rhCOL3 injection. The goal is to establish a targeted rhCOL3 local injection therapy with dual functions of local protection and synergistic treatment, providing a new strategy for the treatment of breast tumors.

Arms & Interventions
rhCOL3 Injection Group
RhCOL3 will be prepared as a 4mg/ml and injected around the tumor. After the surgical margin is confirmed to be safe by rapid frozen pathology during surgery, a second injection of 2ml will be administered around the surgical area skin (at points spaced along the skin incision).
Intervention: Recombinant Humanized Type III Collagen Injection (Biological)
Control Group
4ml of saline will be injected around the tumor before surgery. After the surgical margin is confirmed to be safe by rapid frozen pathology during surgery, 2ml of saline will be injected around the breast surgical area skin.
Intervention: Recombinant Humanized Type III Collagen Injection (Biological)
Outcomes
Primary Outcomes
Short-term postoperative complications after surgery and radiotherapy.
Time Frame: 3 month
The purpose of this study is to assess the incidence rate of short-term complications within 3 months after patients complete surgery and radiotherapy. The main complications are defined as surgery or radiotherapy-related complications occurring during postoperative follow-up, including delayed wound healing, partial skin necrosis, infection, and hematoma and seroma; common adverse reactions related to breast radiotherapy include acute radiation dermatitis, breast edema, pain, etc., and late-stage breast fibrosis, edema, atrophy, telangiectasia, etc.
Secondary Outcomes
- Changes in clinical pathological indicators(3 month)
