Separately, 60 mL of blood is drawn and spun in a centrifuge to obtain platelet-rich plasma (PRP). The fat, PRP, and calcium chloride are mixed. Calcium chloride activates the PRP, forming a thick, gel-like fibrin scaffold that traps the fat fragments into a single, stable block.\n\nHow it is used:\n\nThe lipobolus is placed directly into the cavity left after breast-conserving cancer surgery. This allows for immediate volume restoration in one operation.\n\nWhat makes it different:\n\nStandard fat grafting uses fat alone and often requires 2-3 procedures due to unpredictable abs",[9],[21],{"facility":22,"status":23,"city":24,"state":11,"zip":25,"country":26,"cosmosGeoPoint":27,"geoPoint":32,"contacts":33},"Leningrad Regional Clinical Hospital","RECRUITING","Saint Petersburg","188663","Russia",{"type":28,"coordinates":29},"Point",[30,31],30.31413,59.93863,{"lat":31,"lon":30},[34],{"name":35,"role":36,"phone":37,"phoneExt":11,"email":38},"Aleksandr Bessonov, PhD","CONTACT","+79061300544","aa.bessonov@lokod.ru",{"type":40,"investigatorFullName":11,"investigatorTitle":11,"investigatorAffiliation":11,"oldNameTitle":11,"oldOrganization":11},"SPONSOR","100641341",false,"NCT07658170","Evaluation of the Efficacy and Safety of Using Platelet-rich Fibrin (PRF)-Based Lipobolus for the Immediate Reconstruction of Defects After Breast-conserving Resection for Breast Cancer (Minimally Invasive Primary Immediate Grafting)","MINIPIG","Inclusion Criteria:\n\n* Histologically verified breast cancer (BC).\n* Disease stage from cTis to cT2 according to the TNM classification (AJCC, 8th edition).\n* Tumor grade G1 or G2.\n* Estrogen receptor positivity (ER+).\n* ECOG performance status = 0.\n* Primary tumor size up to 2 cm, based solely on preoperative examination data (mammography, ultrasound, MRI).\n* Indications for breast-conserving surgery (BCS) with a breast resection extent determined by a multidisciplinary oncology board.\n* Submission of an informed voluntary consent (IVC) regarding participation in the study.\n* Ability to understand and comply with the requirements of the study protocol.\n\nExclusion Criteria:\n\n* Male gender.\n* ECOG ≥ 1.\n* Multifocal or multicentric tumor.\n* Grade G3.\n* Triple-negative or HER2-positive tumor with uncontrolled disease.\n* Stage cT3 or higher or distant metastases (M1).\n* Inflammatory breast cancer.\n* Prior neoadjuvant chemotherapy or hormonal therapy.\n* Prior radiation therapy to the breast.\n* Presence of blood coagulation disorders (coagulopathy, thrombocytopathy, thrombocytopenia \\\u003C 100 × 10⁹\u002FL).\n* Taking anticoagulants or antiplatelet agents that cannot be temporarily discontinued.\n* Presence of active infectious diseases.\n* Acute autoimmune diseases.\n* Decompensated comorbidities (diabetes mellitus, cardiovascular diseases, etc.).\n* Body mass index (BMI) \\\u003C 18.5 kg\u002Fm² (insufficient adipose tissue volume for liposuction).\n* Pregnancy or lactation.\n* Mental illnesses that prevent informed consent.\n* Known allergy to local anesthetics or sodium citrate.","FEMALE","18 Years","69 Years",{"count":51,"type":52},30,"ESTIMATED","INTERVENTIONAL",[55],"NA","The goal of this clinical trial is to learn if a special type of fat graft, made by mixing a person's own fat with platelet-rich fibrin (PRF), works to fix breast shape defects after cancer surgery.
