Stuart, Charles Cuoso, Myron The syndrome of inappropriate antidiuretic hormone secretion (SIADH) has been recognized to occur following treatment with vincristine. None of the reports have provided information regarding its potential for recurrence on further chalIenge with vincristine (VCR), an agent generally required for repeated use in patients with malignancies.

The further occurrence of recurrent elevations in ADH excretion 8-10 days following repeated treatment with VCR was also observed. However, SIADH was prevented by prophylactic rigorous fluid restriction. The occurrence of SIADH following VCR therefore does not preclude the further safe usage of this drug.

STUART 316 The patient was started on a chemotherapeutic regimen of oral dexamethasone, ET AL. 6 mg/sq m daily, and intravenous vincristine, 2 mg/sq m weekly for three doses, the first two of which were administered on hospital days 2 and 9 (Fig. I). The early hospital course proved uneventful, but by hospital day 7, the patient had developed abdominal distention and constipation. These symptoms disappeared by day 9. On day 9, the patient experienced two episodes of generalized seizures. These were controlled with intravenous valium. Examination at this time revealed that the patient had a blood pressure of 160/90 mm Hg, and a small retinal hemorrhage inferior-medial to the disc margin. No evidence of volume depletion or overload was present, and laboratory data revealed a BUN of 5 mg/ 100 ml, sodium of 118 meq/liter, chloride of 84 meq/liter, potassium of 4.1 meq/liter, bicarbonate of urine osmolality (Fig. I). and The x-rays 21 meq/liter, of blood of the a 483 sugar, skull were serum osmolality osmoles/liter, M serum calcium of 243 and a urinary and phosphorus, M osmoles/liter sodium urine with excretion analysis, a of concomitant 130 lumbar meq/liter puncture, all normal. The hyponatremia was initially treated with 37 ml of 3% NaCI, followed by 160 ml of 3% NaCI over the next 4 hr. This was followed by a therapeutic trial of 5 cc ethanol. The hyponatremia, however, remained uncorrected by these therapeutic modalities.

Complete normalization of the serum sodium level occurred following total fluid restriction by hospital day 18 (Fig. I). On June 16, 1973, KS received her third dose of vincristine while continuing on approximately 50% maintenance fluids, and while under close surveillance for recurrent hyponatremia. The patient remained clinically asymptomatic and did not manifest a drop in her serum sodium level (Fig. l). Fluid restriction was thereafter gradually withdrawn, and the patient discharged on hospital day 35 following a bone marrow examination that revealed her to be in remission. An EEG, brain scan, and creatinine clearance performed prior to discharge were normal, and a Risa 125i measurement of total blood volume revealed a value of 80.2 ml/kg (normal, 66-88 mI/kg), with a plasma volume of 52.9 mI/kg (normal, 36-49 mI/kg). The patient was continued on maintenance chemotherapy, during the course of which she received subsequent doses of vincristine (Fig. 2). The patient was on no fluid restrictions during these subsequent dosages, and remained asymptomatic with normal serum sodiums. She received prophylactic cranial irradiation (2500 R) during the period September 12, 1973 to September 27, 1973, and at the present time continues in remission without evidence of central nervous system involvement. She manifests some signs of vincristine neurotoxicity, including decreased deep tendon reflexes, alopecia, and ptosis.

In summary, in all the reports to date in which SIADH has occurred following vincristine therapy, no patient was rechallenged with the drug because of the risk of repeated ments the fact that that increased the ADH serious electrolyte hyponatremia secretion disturbances.’6 This case induced by vincristine is true following repeated challenge with report SIADH, docuand vincristine is a reproducible finding. This does not preclude the safe usage of repeated doses of vincristine in the patient with malignancy, in whom repeated doses of the drug may be deemed a therapeutic necessity. REFERENCES 1.
