ABSTRACT<br />

High-dose chemotherapy <strong>and</strong> peripheral <strong>blood</strong> stem cell (PBSC) rescue is<br />

increasingly used to treat patients with advanced epithelial ovarian cancer. Its<br />

greatest benefit appears to be in patients responding to initial therapy or relapsed<br />

patients with platinum-sensitive disease <strong>and</strong> minimal tumor 1 cm. The median<br />

progression-free survival (PFS) <strong>and</strong> overall survival (OS) for the entire group is 7.7<br />

<strong>and</strong> 17.3 months. Those with platinum-refractory disease appear not to benefit,<br />

with a 5.6-month PFS <strong>and</strong> 10.6-month OS. In contrast, patients with relapsed<br />

platinum-sensitive, low tumor bulk have a 16.0-month PFS <strong>and</strong> a 43.3-month OS,<br />

<strong>and</strong> approximately 20% remain progression-free up to 5 years. When treated with<br />

the paclitaxel regimen as consolidation therapy («=10), the PFS was 65% at 26<br />

months from diagnosis. High-dose therapy is associated with an improvement in<br />

PFS <strong>and</strong> OS compared with conventional options for relapsed, responding, low<br />

tumor burden patients. Its role as consolidation therapy of an initial remission<br />

should be verified in a phase III trial.<br />
