abstract
BACKGROUND:
The
superiority of frontline intraperitoneal (IP) over intravenous (IV)
chemotherapy is well established in the treatment of epithelial
ovarian cancer. However, the role of IP chemotherapy in the
second-line setting has rarely been investigated.
METHODS:
Consecutive
patients diagnosed with recurrent epithelial, tubal and peritoneal
cancers between January 2000 and December 2012 were recruited using a
propensity score-matching technique to adjust relevant risk factors.
RESULTS:
In
total,
310 patients were included in the final analysis (94 for
platinum-refractory/resistant disease and 216 for platinum-sensitive
disease). IP chemotherapy demonstrated significantly longer median
progression-free survival than IV chemotherapy (4.9 vs. 2.4 months, p
< 0.001, for platinum-refractory/resistant disease, and 9.8 vs. 6.9
months, p < 0.001, for platinum-sensitive disease).
CONCLUSIONS:
Second-line
IP chemotherapy confers longer progression-free survival than IV
chemotherapy. Large-scale clinical trials should be conducted to
validate the true efficacy.
