^aMotzer et al (1999). Risk factors: Karnofsky PS <80, LDH ⩾1.5 times upper limit of normal, haemoglobin <lower limit of normal, corrected s-Ca >10 mg dl⁻¹ or ion-Ca >upper limit of normal and no prior nephrectomy. No risk factors=favourable prognosis, 1–2 risk factors=intermediate prognosis and >2 risk factors=poor prognosis.
