Boston Medical Center (BMC) researchers have revealed that 1 in 352 women had an unsuspected cancer at the time of gynecologic surgery for disease that was thought to be benign. They observed that minimally invasive gynecologic surgeries have advantages for patients, including shorter hospital stays, quicker recoveries, and less pain. But, power morcellation, a technique which cuts the uterus or fibroid into small pieces in order to extract them from the abdomen through a small incision, may worsen a woman's prognosis if a cancer is morcellated unintentionally.
Using a national insurance database of 55 million women, the researchers looked at cases from 19,500 women who underwent laparoscopic hysterectomies or myomectomies - procedures which typically incorporate power morcellation - to determine how frequently women are diagnosed with cancer after undergoing a gynecologic surgery for a problem that is believed to be benign. The study appeared online in Women's Health Issues.
Michael Paasche-Orlow, general internal medicine physician at BMC and associate professor of medicine at Boston University School of Medicine (BUSM) who is the study's senior author, said, "Our findings show that the risk for morcellating cancer is much higher than previously understood. It makes sense to avoid morcellation for women with cancerous or pre-cancerous lesions. As it is difficult to ascertain in advance, safer alternatives are needed."
Rebecca Perkins, a practicing gynecologist at BMC and associate professor of obstetrics and gynecology at BUSM who is the study's lead author, said, "We are continually seeking opportunities to move gynecologic surgery forward. Because minimally invasive surgery has many advantages, future research should seek to improve techniques to create safer procedures for women."
