Interferons and bladder cancer.

With the introduction of BCG, intravesical instillation of immunotherapeutic agents has become a mainstay of therapy in the treatment of superficial bladder cancer. Interferon is capable of inducing a non-specific cellular and humoral immune response towards tumor cells. It has shown promise in reducing the recurrence and progression rates of superficial bladder cancer. In contrast to BCG, intravesical interferon is associated with minimal side effects and a very low dropout rate. Current research has focused on the use of interferon in combination with immunotherapeutic and cytotoxic drugs.

Charge and length of hospital stay analysis of radical retropubic prostatectomy and transperineal prostate brachytherapy.

PURPOSE: For the treatment of clinically localized prostate cancer radical retropubic prostatectomy with its attendant hospital stay should be associated with higher charges than transperineal prostate brachytherapy. We report a comparative case series to determine patient charges and length of hospitalization of 2 modalities of monotherapy for localized prostate cancer. MATERIALS AND METHODS: A total of 35 consecutive patients with clinically localized prostate cancer underwent radical retropubic prostatectomy (16) or transperineal prostate brachytherapy (19) at the Arthur James Cancer Hospital and Research Institute. Complete charge and length of hospital stay data were collected for each patient. Total charges were calculated and the 2 modalities were compared. RESULTS: Charge data were available in 33 cases. Average total charges in the prostatectomy and brachytherapy groups were $15,097 and $21,025, respectively ($5,928 difference, p <0.0001). The difference increased further when outliers were excluded from study. Average length of hospital stay and average charge in the prostatectomy group were 3.8 days and $1,897. The higher charges for transperineal prostatic brachytherapy were due to dosimetry calculations, radioactive seeds and seed implantation. CONCLUSIONS: At our institution the average total charges for transperineal prostate brachytherapy are significantly higher than those for radical retropubic prostatectomy.

The relationship among dysfunctional elimination syndromes, primary vesicoureteral reflux and urinary tract infections in children.

PURPOSE: We determine whether functional bladder and/or bowel disorders influence the natural history or treatment of children with primary vesicoureteral reflux. MATERIALS AND METHODS: We assessed 143 children with primary vesicoureteral reflux that stopped spontaneously or was surgically corrected for functional bowel and/or bladder disorders, including bladder instability, constipation and infrequent voiding, termed the dysfunctional elimination syndromes. RESULTS: Dysfunctional elimination syndromes were present in 66 of 143 children (43%) thought to have primary vesicoureteral reflux. Of these 66 patients 54 (82%) had a breakthrough urinary tract infection and underwent reimplantation compared to only 18% without the syndromes. Of 70 children who had a breakthrough urinary tract infection dysfunctional elimination syndromes were present in 54 (77%) and absent in 16 (23%). Of the remaining 73 patients who did not have a breakthrough infection dysfunctional elimination syndromes were present in 12 (16%) and absent in 61 (84%). In children with dysfunctional elimination syndromes the resolution of reflux that was 1 grade less severe required an average of 1.6 years longer. After the disappearance of reflux, urinary tract infection developed in 18 children, including 14 (78%) with dysfunctional elimination syndromes. Unsuccessful surgical outcomes involving persistent, recurrent and contralateral reflux occurred only in children with dysfunctional elimination syndromes. CONCLUSIONS: Dysfunctional elimination syndromes are common and are often unrecognized in children with primary reflux. These syndromes are associated with delayed reflux resolution and an increased rate of breakthrough urinary tract infection, which leads to reimplantation surgery. Dysfunctional elimination syndromes also adversely affect the results of reimplantation and represent a risk for recurrent urinary tract infection after reflux resolves. The evaluation and management of dysfunctional elimination syndromes should be an integral part of the treatment of every child with vesicoureteral reflux. Effective evaluation and treatment may be made cost-effective by decreasing the followup, the number of breakthrough urinary tract infections and the number of children requiring reimplantation.
