Renal Impairment in Myeloma
• Severe renal failure is an important complication of myeloma
• 20- 30% of patients have renal impairment at presentation
• 50% of patients at some time
• 2- 5% of patients require long-term dialysis
• Increased mortality

Frequent Causes of Renal Failure in Multiple Myeloma
1. Hypercalcaemia
3. Light chain damage
4. Dehydration
5. Nephrotic drugs – particularly NSAIDS
5. Infection
6. Hyperuricaemia
7. Plasma cell infiltration
8. Amyloidosis

Rationale for Use of Bortezomib Combination Therapy in Patients with Renal Failure
1. Significant activity in patient with relapsed MM
2. Increased efficacy with addition of dexamethasone
3. Synergy with other myeloma treatments
4. Inhibition of NFκ B reduces peritubular inflammation
5. All of above
6. None of above

Bortezomib in patients with renal failure requiring dialysis
• High response rates
• Most adverse events were mild to moderate and manageable
• Incidence and severity of adverse events comparable to those of patients with normal renal function

Drugs should be administrated on Days 1, 4, 8, 11 in the following order.1. Dexamethasone 40 mg i.v.2. Doxorubicin 9 mg/m2/d i.v.3. Bortezomib 1.0 or 1.3 mg/m2 i.v.
Restart next cycle on Day 22.
The Bortezomib dose is planed to be 1.3 mg/m2. Nevertheless for the safety reasons, the first 3 patients are going to be treated by 1.0 mg/m2 Bortezomib.
