Cancer and Surgery

Tumour Promoting Effects of Surgery – Study

Journal of Anesthesiology (V 94, No 6, June 2001) - Surgical resection of tumors is an important aspect of cancer treatment. Unfortunately, it is becoming apparent that the perioperative period is characterized by pronounced immunosuppression, which may increase metastatic development at this susceptible period. This study assesses whether the use of regional anesthesia (spinal block) attenuates the promotion of metastasis by surgery.

Surgery Induced Angiogenesis in Breast Cancer – Study

International Journal of Surgery (V 3 No 3 2005) - "Does surgery induce angiogenesis in breast cancer? Indirect evidence from relapse pattern and mammography paradox". This study by Retsky M, Demicheli R, Hrushesky WJ examines if removing tumors cpuld stimulate cancer relapse by removing the source of inhibitors of angiogenesis (blood vessel creation) or if growth factors appear in response to surgical wounding.
