Bendamustine is a bifunctional alkylating agent with cytotoxic activity aga
inst human ovarian and breast cancers in vitro. It shows only partial in vi
tro cross-resistance with cyclophosphamide, melphalan. carmustine and cispl
atin.
Bendamustine as monotherapy or as part of combination chemotherapy protocol
s for first-line or subsequent treatment produced objective response rates
of 61 to 97% in patients with Hodgkin's disease or non-Hodgkin's lymphoma (
NHL) [41 to 48% in high grade NHL].
In patients with multiple myeloma, a bendamustine/prednisone regimen produc
ed a higher rate of complete response (32 vs 11%) and more durable response
s than a melphalan/prednisone regimen.
Substitution of bendamustine for cyclophosphamide in a standard first-line
COP regimen (cyclophosphamide, vincristine and prednisolone) yielded simila
r response rates in patients with advanced low grade NHL.
Substituting bendamustine for cyclophosphamide in the CMF protocol (cycloph
osphamide, methotrexate and fluorouracil) prolonged remission from 6.2 to 1
5.2 months in patients with metastatic breast cancer.
The most common adverse events in patients receiving bendamustine are haema
tological events and gastrointestinal disturbances. Bendamustine has a rela
tively low propensity to induce alopecia.
