One in seven women will die within 2 months of being diagnosed with ovarian cancer, a new report from the United Kingdom states. But if diagnosed at the earliest stage, 9 in 10 women will survive. Two thirds of women are now diagnosed late, when the cancer is harder to treat.
Diagnosis is difficult for many reasons, among them that women sometimes think symptoms are a natural part of menopause and don’t acknowledge or report them. Clinicians may mistake abdominal symptoms for those of a bowel condition or bladder problem. Almost half of GPs (46%) in the United Kingdom mistakenly believe that ovarian cancer symptoms present in only the later stages of the disease.
Cervical Screening Does Not Detect Ovarian Cancer
Additionally, there are misconceptions regarding cervical cancer screening — one study found that “40% of women in the general public mistakenly believe that cervical screening detects ovarian cancer.” But there is no current screening program for ovarian cancer in the United Kingdom or United States.
During a pelvic exam, the physician feels the ovaries and uterus for size, shape, and consistency and that can be useful in finding some cancers early, but most early ovarian tumors are difficult or impossible to feel, the American Cancer Society notes.
Recognizing the Red Flags
Victoria Barber, MBBS, a general practitioner in Northamptonshire and a Primary Care Advisory Board member with the Target Ovarian Cancer program in the United Kingdom published a paper in the British Journal of Nursing (2024 Mar 7. doi: 10.12968/bjon.2024.33.5.S16) on the program’s efforts to urge clinicians to recognize ovarian cancer red flags and to “never diagnose new-onset irritable bowel syndrome or overactive bladder in women over 50 without ruling out ovarian cancer.”
She says nurses should be involved to help with earlier diagnosis of ovarian cancer as they are often involved in evaluating urine samples. Nurse practitioners, she notes, are typically included in consultations for abdominal symptoms and potential urinary tract infections.
“If the woman is recurrently presenting with urinary symptoms, sterile midstream urine samples should raise alarm,” she says. “The woman may have diabetes, an overactive bladder, or interstitial cystitis; however, urgency and frequency are some of the symptoms of ovarian cancer, and they need investigation.”
Persistent Systems Over Age 50
The paper lists ovarian cancer symptoms from the UK’s National Institute for Health and Care Excellence and notes that among red flags are having any of the following persistently/frequently (particularly more than 12 times per month and especially if the woman is 50 years or older):
Early satiety and/or loss of appetite Abdominal bloating Pelvic or abdominal pain Urinary urgency/frequency
Other symptoms could include:
Changes in bowel habits (eg, diarrhea or constipation) Extreme fatigue Unexplained weight loss
Diagnosis Challenges Similar in the United States
Ernst Lengyel, MD, PhD, UChicago Medicine’s Chairman of the Department of Obstetrics and Gynecology in Chicago, Illinois, who was not involved with the paper, said the situation in the United States is similar to that described in the United Kingdom.
“The diagnosis is delayed because the symptoms are unspecific. The problem is that ovarian cancer is so rare, and primary care physicians or nurse practitioners have to consider over 100 differential diagnoses,” he says.
In the United States, he says, it is likely easier to get in and see a physician because of the private insurance options and because there are more gynecologic oncologists in large urban areas. Getting imaging approved — such as ultrasound and computed tomography scans — is also easier in the United States.
Still, “there is no effective way to diagnose ovarian cancer early,” he says. “No single test or combination of symptoms can be used as a screening test.”
The CA-125 blood test measures proteins that can be linked with ovarian cancer, but is not a screening test, he notes.
“Large UK and US studies have not been able to show a survival benefit with ultrasound, serial CA-125, or a combination thereof,” Dr Lengyel said.
Weight Gain May Also Be a Sign
A broad range of clinicians should be aware of the symptoms the author mentions, he says, especially primary care physicians, nurse practitioners, and obstetrician/gynecologists.
“Too often, symptoms that women report are ignored and treated as unspecific or psychosomatic,” Dr Lengyel says. “It is easy to disregard recurrent complaints and move on instead of being vigilant and working them up. Ironically, women with ovarian cancer can initially gain weight, which is counterintuitive as most doctors believe that patients with cancer lose weight. However, if they develop abdominal fluid, a patient often gains weight.”
Dr Barber and Dr Lengyel reported no relevant financial relationships.
