Intraoperative autotransfusion in urologic oncology.

Area of Science:

• Oncology
• Surgical Innovation
• Transfusion Medicine

Background:

• Autotransfusion is recognized for its benefits but its use in cancer surgery is limited due to concerns about tumor cell dissemination.
• Preventing transfusion-transmitted infections like AIDS and hepatitis is an increasing concern, highlighting the potential value of autotransfusion.

Purpose of the Study:

• To evaluate the safety and efficacy of autotransfusion in patients undergoing major surgery for genitourinary tumors.
• To assess the risk of tumor metastasis associated with autotransfusion in this patient population.

Main Methods:

• Autotransfusion using a Haemonetics Cell Saver was performed on 49 patients undergoing major genitourinary tumor surgery.
• Procedures included radical cystectomy, prostatectomy, and nephrectomy.
• Patient follow-up involved clinical examinations, imaging (chest roentgenograms, bone scans, CT scans), and laboratory tests.

Main Results:

• Five out of 49 patients developed metastases between 12 and 23 months post-surgery.
• The incidence and pattern of metastatic spread did not suggest autotransfusion as a cause of tumor dissemination.
• Autotransfusion may significantly reduce or eliminate the need for homologous blood transfusions.

Conclusions:

• Autotransfusion is a safe procedure for patients undergoing major genitourinary cancer surgery.
• The study found no evidence linking autotransfusion to increased tumor metastasis.
• Autotransfusion offers a viable alternative to homologous transfusions, potentially improving patient outcomes and reducing risks.
