The activity of HDI in these pretreated ASTS patients and the apparent circumvention of SDI resistance suggest a real dose-response relationship for ifosfamide and deserve further evaluation. Although toxic, this treatment appears feasible and manageable using routine clinical support. Since prophylaxis of ifosfamide-induced renal damage remains unknown, frequent monitoring of renal and tubular functions during therapy is highly recommended.

Results of the Hermine study examining the use of trastuzumab for metastatic breast cancer patients in routine practice, including patients who received trastuzumab treatment beyond progression, are reported. The cardiac safety of trastuzumab in this setting is also reported.

These results suggest that downregulation of CD95 and upregulation of Fas-L in melanoma might be considered as concomitant with disease progression.

Most cases of advanced carcinoma of the prostate are hormonosensitive. The use of combined androgen blockade (CAB) seems to improve survival and quality of life, but only when combined with chemical castration by luteinizing-hormone-releasing hormone analog and without the use of steroidal antiandrogens. After CAB, further hormonal treatments remain efficacious, such as antiandrogen withdrawal followed by estrogens, aromatase inhibitors, and hormone-refractory prostate cancer multiple cytotoxic agents. For painful bone lesions, external beam radiotherapy, biphosphonates, and strontium 89 or samarium 153 provide pain relief. The use of new methods for the evaluation of response and quality of life will allow the rapid identification of effective treatments and permit powered phase III trials.

These results seem to indicate a possible synergy between CDDP/rIL-2 and IFN alpha in MM.
