Ovarian cancer is the deadliest of all pelvic cancers for a woman. Overall, about one in seventy-two women will develop this disease. Of these, over half will have died within five years of diagnosis. If ever a disease cried out for a screening test, this would be it. Unlike the breasts, for example, the ovaries lie deep within the body and are therefore less accessible to physical exam. The bimanual pelvic exam is also uncomfortable and the discomfort causes women to tighten the abdominal muscles, making detection that much more difficult. If you add factors such as obesity and scars from Cesareans, you find the examiner's ability to feel the ovaries decreases exponentially.
Ultrasound has been suggested as a screening technique since the 1980's. In the US, the leading proponent of transvaginal ultrasound for ovarian cancer screening has been Dr. Van Nagell's group at the University of Kentucky.
Some have tried utilizing blood markers such as CA-125. Most recently, the group at MD Anderson found that evaluating changes in the level of CA-125 over time and combining that with transvaginal ultrasound yielded promising results in finding more early ovarian cancers.
Others, however, have not met with similar success. The US Preventive Services Task Force, in fact, recommends not screening for ovarian cancer.
Later this year, The UKCTOCS,the largest randomized trial of screening will publish its results, hopefully shedding more light on this issue.
In the meantime, there are some women at significantly higher risk for ovarian cancer, those whose strong family history or genetic tests place in a high risk group. For this group of women, screening, with all its foibles, should be considered. For more information or to schedule an ultrasound, please call: (718) 925-6277.
