Abstract:
Objective: Evaluate the efficacy and toxicity of the
weekly regimen of Taxol and Carboplatinum in recurrent platinum
sensitive ovarian cancer patients.
Methods: Under
IRB approval, 20 patients with recurrent platinum sensitive ovarian
cancer were treated with a regimen of weekly Paclitaxel (80 mg/m2)
and weekly Carboplatinum (AUC 2). Patients were evaluated for response
by both clinical and radiographic methods and CA-125 response by
the Restin criteria. Toxicities were graded according to the common
toxicity criteria. Patients were treated from 1999 through 2002.
The mean platinum-free interval was 20.9 months with a range of
8-56 months. Seventeen patients were evaluable by clinical methodology
and 18 patients by CA-125 response. Patients were eligible if more
than 6 months since treatment with platinum containing compounds
and clinical evidence of recurrence or a CA-125 which was doubling
and greater than 70. Patients were evaluated for response after
8 cycles of treatment.
Results:
The 20 patients received an average of 13.4 cycles of treatment
(range 2-18). Of the 17 patients with clinically evaluable disease,
9 had a complete response, 5 had a partial response and 3 had stable
disease. In the 18 patients evaluable by the Restin criteria showed
14 patients with a complete response and 4 patients had a partial
response stable disease. Overall response rate by clinical criteria
was 82%(14/17) and by CA125 100%(18/18). Toxicities included Grade
3 neutropenia in 20% (4/20), Grade 2 neurotoxicity in 10% (2/20),
allergic reactions in 15% (3/20) and Grade 3 anemia in 5% (1/20).
The median progression free survival was 11.2 months with a range
of 2-24 months.
Conclusions:
Weekly paclitaxel and weekly carboplatinum are a highly effective
and well-tolerated regimen. Allergic reactions are no more common
than in standard retreatment regimens. This dose scheduling deserves
consideration for front line therapy.
