N2 - Background. The present study was conducted to evaluate the efficacy and toxicity of a combination of paclitaxel, cisplatin and gemcitabine in patients with carcinoma of unknown primary site (CUP). Patients and methods. Patients with CUP, ECOG performance status 01 and age between 18 and 65 years old were treated with paclitaxel 175 mg/m2 day 1, cisplatin 75 mg/m 2 day 1 and gemcitabine 1000 mg/m2 day 1 and 8 in a three-week schedule. Results. Ninety-eight patients were enrolled between 1998 and 2008. Ninety-one patients had target lesions according to the RECIST guidelines. The overall response rate was 42.9% (39 patients), including five complete responses (5.5%) and 34 partial responses (37.4%). The median survival time was 10.7 months, and the survival rates at one and two years were 42% and 14%, respectively. The most frequent grade 3 or more adverse events were neutropenia and thrombocytopenia. There were 3 treatment-related deaths. Conclusions. Combination of paclitaxel, cisplatin and gemcitabine is an active regimen in patients with CUP with response and survival rates at least similar to other platinum- and taxane-containing regimens. The treatment was well tolerated by most patients although neutropenia and thrombocytopenia were relatively common. The present regimen represents an attractive regimen in younger CUP patients with a good performance status.
