OBJECTIVE: To examine the symptoms of ovarian cancer in patients compared w
ith symptoms experienced by healthy women using a case-control design.
METHODS: Cases (n = 168) were women with ovarian cancer diagnosed at two ho
spitals in New York between 1994 and 1997 who were interviewed shortly afte
r diagnosis. They were compared with healthy women (n = 251 controls) from
the community. Women were asked about the prevalence, duration, and constan
cy of eight symptoms and about use of three types of medications in the 6 t
o 12 months before diagnosis (cases) or interview (controls).
RESULTS: Nearly all the cases (93%) reported at least one symptom, compared
with 42% of controls. The most common symptoms among cases were: unusual b
loating, fullness, and pressure in the abdomen (71%); unusual abdominal pai
n or lower back pain (52%); and lack of energy (43%). The proportions of co
ntrols reporting these symptoms were 9, 15, and 16%, respectively, resultin
g in odds ratios and 95% confidence intervals of 25.3 (15.6, 40.9), 6.2 (4.
0, 9.6), and 3.9 (2.5, 6.1), respectively, for these symptoms. Bloating, fu
llness, and pressure was of more recent onset among cases than controls (4.
9 months compared with 7.6 months, P =.01). There were only minor differenc
es in reported symptoms between cases with early and later stage disease.
CONCLUSION: Unusual bloating, fullness, and pressure, abdominal or back pai
n, and lack of energy are prominent symptoms in women with ovarian cancer a
nd distinguish them from controls. Information on symptoms may make women a
nd physicians more aware of changes associated with ovarian cancer. (C) 200
