Fatal tumour lysis syndrome: case reportA 62-year-old woman developed acute tumour lysis
syndrome and died from refractory hyperkalaemia andcardiorespiratory arrest during treatment with antineoplasticsfor non-Hodgkin’s lymphoma. She had a history of myocardialinfarction with congestive heart failure and obstructivepulmonary disease 3 years earlier. She had also been treatedwith mediastinal radiotherapy for Hodgkin’s disease when shewas aged 32 years; the tumour never recurred.
After hospitalisation, the woman received prehydration withIV saline and allopurinol. Antineoplastic therapy, consisting ofcyclophosphamide 1300mg, doxorubicin 90mg, vincristine2mg and prednisone 100mg, was started 24 hours later. Shedeveloped bradycardia and cardiogenic shock 18 hours afterstarting antineoplastic therapy. Her BP was 80/50mm Hg andan ECG revealed that her ventricular rhythm was 35 beats/minwith wide QRS complexes. Soon after, she developedcardiorespiratory arrest due to asystole.
The woman was initially treated with intubation,cardiopulmonary resuscitation, atropine and epinephrine[adrenaline]. She received further treatment with a temporaryexternal pacemaker and a dopamine infusion. Blood testsrevealed severe hyperkalaemia, hypocalcaemia, renal failureand metabolic acidosis. She subsequently received IV calciumgluconate, sodium bicarbonate, glucose and insulin, and aninternal pacemaker was inserted. She died shortly after fromrecurrent asystole. Acute tumour lysis syndrome was thendefinitively diagnosed from laboratory results.
Author comment: The effects of acute tumour lysissyndrome may have been worsened by doxorubicincardiotoxicity. Cardiotoxicity associated with doxorubicintherapy is increased by a history of anthracyclineadministration, heart failure and previous mediastinalradiotherapy. ‘This may be a possible explanation for the factthat our patient developed cardiac arrhythmias due to ATLS[acute tumour lysis syndrome], without fulfilling all the criteriaof a high risk patient.’Van Der Klooster JM, et al.
