Can ovarian cancer come back after a hysterectomy?
“The short answer is yes,” says gynecologic oncologist Peter Frederick, MD, FACOG, Associate Professor and Clinical Chief of Gynecology at Roswell Park. “What matters most in terms of whether ovarian cancer will recur is the stage of disease at the time of diagnosis and if all visible cancer was removed at the time of surgery. A patient’s age and overall health, as well as the specific subtype of ovarian cancer, are also important in determining recurrence risk. Other factors can be more difficult to predict, such as the cancer’s sensitivity to treatments such as chemotherapy.”
This will be complicated, as a result of many individuals assume a hysterectomy removes all of the reproductive organs. Technically, hysterectomy means eradicating solely the uterus (or womb), leaving the ovaries and fallopian tubes in place. Even a whole hysterectomy removes solely the uterus and the cervix, which by itself shouldn’t be a therapy for ovarian cancer. The ovaries are separate constructions, and the surgical procedure to take away ovaries is known as an oophorectomy. If the fallopian tubes are eliminated together with the ovaries, the process is known as salpingo-oophorectomy.
For girls identified with ovarian cancer, the usual surgical procedure contains elimination of the uterus, cervix, ovaries and fallopian tubes. Sometimes the uterus and one ovary or a part of an ovary could also be spared, an possibility utilized in particular circumstances—for instance, in younger girls with early-stage ovarian cancer who want to retain fertility and hormonal operate. “The surgical approach and extent of surgery can often be uniquely tailored, depending on a patient’s individual circumstances,” says Dr. Frederick. “I would encourage patients to have these discussions with their cancer surgeon prior to surgery.”
If ovarian cancer does return after surgical procedure, mostly it is going to recur within the peritoneal cavity, the area under the diaphragm that features the stomach and pelvic constructions. “Often we will monitor for recurrence with a combination of tumor markers such as CA-125, physical examination —monitoring for signs and symptoms, such as abdominal bloating or pelvic pain—and, in some cases, imaging tests, such as CT scans.”
Stage at Diagnosis Most Important
Overall, 80% of sufferers with early-stage ovarian cancer are freed from illness at 5 years, however there’s a super distinction within the recurrence fee based mostly on the stage of the illness on the time of prognosis. Like many strong tumor cancers, ovarian cancer is classed into 4 major phases. With stage 1 cancer, wherein cancer cells are confined to at least one or each ovaries, the danger for recurrence is low, about 10%. As a end result, five-year survival is round 90%. Unfortunately, solely a small variety of girls have their cancers identified at this early stage.
“You can see recurrence at any stage,” says Dr. Frederick. “But the more advanced the disease is at diagnosis, the greater the risk for recurrence.” With stage 2 cancers, the danger of recurrence is about 30%; for stage three cancers—the commonest stage at prognosis for epithelial ovarian cancer—the danger is about 70%; and in stage four cancers, the place there’s distant unfold of illness, the danger of recurrence could also be as excessive as 90%.
Staging is a description of how a lot the cancer has unfold on the time of prognosis. This is vital as a result of the stage can information the particular therapy advice and have an effect on prognosis. In ovarian cancer, staging is set by tissue biopsy, both executed on the time of surgical procedure or confirmed by a needle biopsy. Sometimes it’s apparent if ovarian cancer has unfold to different constructions on the time of prognosis. In this case, the surgical purpose is usually cytoreduction—to soundly take away all seen tumor.
In different circumstances, different constructions within the pelvis might seem regular however nonetheless have microscopic illness. In these surgical procedures, the doctor additionally biopsies or removes different tissues to see if and the place the cancer might have unfold. These procedures, known as surgical staging, contain taking samples from a number of areas of the pelvis and stomach, together with lymph nodes, peritoneum (the internal lining of the stomach and pelvic cavities), omentum (fatty tissue connected to the colon) and any fluid buildup within the stomach cavity (known as ascites). In addition, the peritoneal cavity could also be bathed in saline and a pattern of the fluid examined.
Surgical staging and cytoreduction play important roles within the therapy of ovarian cancer. “Patients with ovarian cancer treated by high-volume surgeons at high-volume medical centers tend to have the best outcomes,” says Dr. Frederick.
“This is why a second opinion by a gynecologic oncologist—a subspecialist in cancers of the female reproductive system—is so important. We can work with our multidisciplinary team to offer you a tailored surgical approach, review your pathology and imaging scans, and, if applicable, provide access to the latest chemotherapy treatments and clinical trials.”
