title: Hydroxyurea as a modulator of multidrug resistance in resistant solid tumor.
abstract: We enrolled 11 consecutive pre-treated resistant advanced cancer patients to receive hydroxyurea (HU) (as modulator of MDR) 10 mg/kg/day (d) p.o. d 1-14 in association with DXR (d 15) alone or in combination with VDS (d 15) or VP16 (d 15-17) in presence, respectively, of soft tissue sarcoma, breast carcinoma, lung and gastric carcinoma. We obtained a stabilization of disease (NC) in 62.5% of patients, with a mean duration of 6 months. The mean survival was 12.2+ months for NC and 6 months for progressive disease (PD). No severe or unexpected adverse events were reported over 34 cycles administered; the most frequently recorded side effects were haematological and gastrointestinal toxicity. It seems that at the dosage we used, HU is poorly active in overcoming MDR; further studies with larger number of patients and different dosage are needed.
