NEW DRUG DEVELOPMENT AND TREATMENT FOR SUPERFICIAL BLADDER CANCER
Phase I Drug Trial Using Gemcitibine
Intra vesical Gemcitibine therapy for BCG refractory superficial bladder cancer
Superficial bladder cancer remains the
most common form of bladder cancer encountered in the
United States. Over 75% of patients with bladder cancer
have the superficial form of the disease and require
long term therapy and monitoring.
One of the mainstays of therapy for
patients with superficial bladder cancer who suffer multiple
relapses or who have high grade tumors with or without
invasion of the bladder lining or carcinoma in situ is
the use of intra vesical chemotherapy or immunotherapy.
Since it's introduction in the 1970s
Bacille Calmet-Guerin has consistently provided the best
control of relapse and some believe progression in patient
with high risk bladder cancers. Other agents with slightly
less efficacy but substantially fewer side effects such
as Mitomycin C have also been used with good effect in
many patients.
New drugs are needed however because
even the best therapy available drugs today only provide
a 30-50% chance of long term disease control.
The Bladder Cancer Research Center has
a strong investigational interest in new agents to treat
superficial bladder cancer. In the past 2 years, two
novel agents (Taxol and Gemcitibine) have been studied
in patient with chronically relapsing low grade superficial
disease. The Gemcitibine trial is still accepting patients.
Additional agents will be introduced in the coming year. |
