Abstract: Tumor-free techniques refer to a series of measures taken during the operations for malignancies to prevent tumor cells from shedding，spreading，and implanting that cause recurrence and metastasis. The techniques open surgeries for gynecological malignancies should be implemented by no-compression，sharp dissection，isolation of tumor，en bloc resection，prevention of cancer cell contamination，and preclusion of intraoperative spread in order to achieve optimal oncological outcome.

Key words: gynecological malignancy, open surgery, tumor-free techniques
