The presence of multidrug-resistant (MDR) cells in a solid tumor constitutes a major problem in cancer therapy. Current thinking suggests that the resistant phenotype arises de novo during the tumor's evolution via somatic mutation mechanisms. The proportion of MDR cells, once established, may be enriched during therapy as a consequence of differential cell kill. Michelson et al have developed mathematical models of these phenomena to gain an insight into the dynamics of clonal subpopulation emergence in general and MDR emergence in particular, and I now show that one unexpected consequence of therapy may be the facilitation of MDR emergence due to damage inflicted on the host. The therapeutic damage to the host is modeled as a decreased ability to carry a specific tumor burden.

Carboplatin is one of a series of cisplatin analogs now undergoing clinical investigation. Phase I and II trials in adults demonstrate activity in a number of human cancers and less toxicity than might be expected with the parent compound. This phase I trial was undertaken to establish the maximum tolerated dose and the recommended phase II dose in children treated by a 1-hour iv infusion every 4 weeks. Twenty-nine patients with recurrent or progressive tumor were entered in this study at the Children's Hospital of Los Angeles and Children's Memorial Hospital in Chicago between April 12, 1983, and November 27, 1984. Beginning with a dose of 350 mg/m2 (about 80% of the adult phase II dose), we escalated the dose in groups of patients to 670 mg/m2; dose-limiting myelosuppression was encountered at this dose. Fifty-seven infusions are at least partially evaluable for toxicity. Asymptomatic hypomagnesemia, hypocalcemia, and ototoxicity were observed infrequently, and nausea and vomiting were mild. One patient with a mixed glioma of the posterior fossa achieved a good partial response lasting 9 months. Stable disease for greater than or equal to 6 months was observed in three patients: one each with ependymoma, brain stem glioma, and spinal cord astrocytoma. The recommended pediatric phase II dose is 560 mg/m2 given as a 1-hour iv infusion every 4 weeks.

Many chemotherapeutic agents are nephrotoxic and/or excreted via the kidney. Thus, careful evaluation of renal function is important since drug dosages are often lowered in patients with impaired renal function. When the creatinine clearance as calculated by the method of Cockcroft and Gault from the patient's age, weight, and serum creatinine was compared to the measured creatinine clearance in the same patients, the correlation coefficient was low (r = 0.40) and the average difference between the predicted and measured creatinine clearance values was 25.3%. Thus, in our patient population, creatinine clearance calculated by the method of Cockcroft and Gault did not correlate well with measured creatinine clearance and thus was not useful as a clinical tool.
