Taxol is a new antimicrotubule agent that, besides a well known efficacy against solid tumors, has shown activity in non-Hodgkin's lymphomas too. We therefore investigated its in vitro cytotoxic activity against cells from patients affected by chronic lymphocytic leukemia (CLL). Peripheral blood lymphocytes from 46 CLL patients were incubated for four days with Taxol at doses ranging from 0.01 to 10 mM and the cytotoxicity was evaluated by a colorimetric method (XTT). In most samples Taxol was inactive and the IC50 was > 10 mM in 40 out of 46 patients. It is worthwhile noting that four of the six in vitro responsive patients had unfavourable clinical features. In three unresponsive patients we also observed that Taxol was not able to induce apoptosis in vitro. In conclusion, based on in vitro data, it seems that Taxol is not an active drug in standard CLL but we cannot exclude some efficacy in other more rapidly proliferating lymphoproliferative disorders.

Due to its selective overexpression on the malignant cells of Hodgkin's lymphoma (HL) and large cell anaplastic lymphoma (ALCL), CD30 is an excellent target for immunotherapy of these diseases. The fully human monoclonal anti-CD30-antibody 5F11 has been shown to be effective against CD30-expressing cell lines both in vitro and in vivo. In addition, 5F11 shows promising antitumor activity in phase 1/2 clinical trials. To extend these promising results, the authors evaluated combinations of 5F11 with conventional cytostatic drugs against a variety of lymphoma cell lines in vitro. Most combinations tested showed at least additive cytotoxic effects on the HL-derived cell lines L428, L540, and L1236 and the ALCL-derived cell line Karpas 299 as measured by proliferation assays (XTT) and the induction of apoptosis (annexin-V FACS analysis). The most impressive results were detected with the combination of 5F11 and gemcitabine or etoposide. The data suggest that the combination of the human antibody 5F11 with conventional chemotherapy might be beneficial in the combined chemo-immunotherapy of CD30-positive lymphomas.
