CHICAGO—A new report offers a picture of patients seeking care for breast and gynecological cancers within the US Department of Veterans Affairs (VA) health care system: They are somewhat younger than their counterparts in the general population, and those with breast cancer are much more likely to be men.
It is not clear whether these numbers are purely a reflection of the unique population within the VA or whether there is a more complicated explanation. Researchers also found that more than half of those with newly diagnosed breast, cervical, and ovarian cancers lived in the South compared with few (8%-13%) who lived in the Northeast.
The study findings were released in a poster at the 2023 annual meeting of the Association of VA Hematology/Oncology. Sarah Colonna, MD, study coauthor and medical director of breast oncology for the national VA, said in an interview that it is important to understand statistics regarding breast and gynecological cancer within the VA, especially as the system focuses more on patients with the conditions. And, she said, the wave of women who joined the military in recent decades are getting older and more likely to need oncology care. “We know women veterans are coming: They’re aging, and they’re going to get cancer.”
Colonna and colleagues examined statistics from the VA Corporate Data Warehouse to determine how many veterans were newly diagnosed with breast, uterine, ovarian, cervical, and vulvovaginal cancer in 2021 and 2022. The researchers compared their findings with 2020 statistics about the general population from the SEER database.
Within the VA, there were 3304 cases of breast cancer (mean age, 59 years; range, 23-99; mean body mass index [BMI], 31), 344 cases of cervical cancer (mean age, 46 years; range, 22-90; mean BMI, 29), 177 cases of ovarian cancer (mean age, 57 years; range, 24-80; mean BMI, 29), 365 cases of uterine cancer (mean age, 60 years; range, 24-85; mean BMI, 35), and 32 cases of vaginal/vulvar cancer (mean age, 56 years; range, 24-75; mean BMI, 31).
In contrast, the mean ages at diagnosis for the general population were slightly higher at 63 years for breast cancer, 50 years for cervical cancer, 63 years for ovarian cancer, and 63 years for uterine cancer. Vaginal/vulvar cancer was a bit of an outlier at mean age 69 years for the general population vs 56 years for the VA population; however, the number of cases in the latter group was quite low at 32 patients.
Overall, gynecological cancers were diagnosed at an average age of 55 years among the VA population vs 61 years among the general population. Men made up 11% of breast cancer cases in the VA vs 1% in the general population. “Of course, we have 10 times the proportion of men than in the outside,” said Colonna, an oncologist with the Huntsman Cancer Institute/Wahlen VA Medical Center in Utah. That may explain the difference, “but nobody knows for sure,” she said.
Patients Within the VA with the following cancers were more likely to be Black veterans than in the general population: breast, 30% vs 12%; cervical, 20% vs 14%; ovarian, 28% vs 10%; uterine, 25% vs 12%; and vaginal/vulvar, 44% vs 10%. This could reflect the fact that 30% of women treated within the VA are Black women vs 12% in the general population, Colonna said. Unfortunately, she said, “black women with breast cancer, tend to do really poorly. They tend to get it young, and they tend to die.”
