Abstract
Objective
A
rise of the CA125 marker above the normal range during follow-up of
ovarian, primary peritoneal and tubal carcinoma patients with a complete
clinical response after initial treatment signifies recurrence. We
assessed whether the pattern of CA125 ascent to above the normal range
at recurrence is associated with outcome.
Methods
The
records of all recurrent ovarian primary peritoneal and tubal carcinoma
patients diagnosed during 1998–2007 were abstracted. Included were
patients who fulfilled the following criteria: CA125 levels were
≥ 35 U/mL at diagnosis and at recurrence, they had full primary
treatment with a complete clinical and radiographic response, were
followed-up according to schedule, and had at least two CA125 results
within the normal range during follow-up. Two patterns of CA125 ascent
to above the normal range were compared: a gradual rise and an abrupt
rise.
Results
52 patients with
recurrent disease who met the inclusion criteria were identified. The
median progression free and overall survival were significantly longer
in patients with a gradual than in those with an abrupt rise (22.96 vs
14.07; P = 0.0014; and 44.37 vs. median not yet reach, respectively).
Multivariate analysis showed that the pattern of CA125 ascent is an
independent predictor of progression free and overall survival.
Conclusions
Our
data seem to indicate that at recurrence the pattern of ascent of serum
CA125 levels to above the normal range in patients in complete clinical
remission is of prognostic value.
Highlights
►
Epithelial ovarian cancer patients with complete clinical response to
primary treatment are usually followed with repeat CA-125 tests.
► Two patterns of CA-125 ascent to above the normal range were assessed in patients with recurrent disease.
► Patients with gradual rise had a significantly longer progression-free and overall survival compared to patients with abrupt rise.
► Two patterns of CA-125 ascent to above the normal range were assessed in patients with recurrent disease.
► Patients with gradual rise had a significantly longer progression-free and overall survival compared to patients with abrupt rise.
