| Summary|| |
It is generally assumed that intravesical bacillus Calmette-Guerin (BCG) should be avoided in the setting of immunosuppression. This retrospective study from the Memorial Sloan-Kettering Cancer Center was undertaken to assess the safety and efficacy of intravesical BCG instillation in 24 steroid treated and immunocompromised patients between 1991 to 2004. Four patients (17%) had active lymphoma or chronic lymphocytic leukemia during BCG administration and 21 (88%) had a concurrent condition for which oral steroids (11), inhaled steroids (14) or oral and inhaled steroids (4) were administered. All patients received weekly BCG therapy for 6 consecutive weeks. BCG was administered as 81 mg in 50 ml saline retained for 2 hours starting 2 to 3 weeks after the resection. The overall BCG response rate at 6 months was 58%. Ten of the 24 patients had disease recurrence and 3 had disease progression at a median follow-up of 63.5 months. Only one patient treated with oral steroids had adverse effect in the form of self-limited febrile disease and worsening of myalgia 48 hours after his third BCG cycle. They concluded that intravesical BCG is a viable treatment option in this group of patients and that the response rate at 6 months and the side effect profile in these patients were comparable to those patients with no evidence of immunosuppression.
| Comments|| |
There are two important issues that come to the mind when intravesical BCG is used in immunocompromised patients. Firstly, whether there is an increased risk of systemic BCG toxicity in this group of patients and secondly if the local inflammatory immune response will be adequate to achieve an optimal antitumor effect. This study provides an affirmative answer to both these questions. Since the number of immunocompromised superficial bladder cancer patients at most institutions will be small, level one evidence (randomized control trials) on the subject is unlikely to be available and we will have to go by such studies. The major limitation of this study is that most patients had minimal immunosupression (inhaled or low dose oral steroids). There is no quantification of the level of immunosuppression. These results should not be the basis for the use of intravesical BCG in severely immunocompromised patients. Further studies are warranted to assess the safety and efficacy of intravesical BCG in critically immunocompromised patients. There is level 1 evidence that intravesical mitomycin C is equally effective as intravesical BCG in high risk superficial bladder cancer except in those patients with Cis and it should be the first intravesical agent in immunocompromised patients.
