1
HIGH-DOSE TREATMENT
AUTOLOGOUS PERIPHERAL BLOOD PROGENITOR
CELLS ALLOGRAFTING
2
HIGH DOSE TREATMENT AND ALLOGRAFTING
  • TERMINOLOGY CONFUSING (USED IMPRECISELY)

HIGH DOSE TREATMENT BEAM SUPPORTED
BY AUTOLOGOUS PERIPHERAL BLOOD PROGENITOR
CELLS (PBPC)
3
HIGH DOSE TREATMENT AND ALLOGRAFTING
  • ALLOGRAFTS

- SIBLING OR MATCHED UNRELATED DONOR (MUD)

(NOW VOLUNTEER UNRELATED DONOR, VUD)
- MYELOABLATIVE e.g.CYCLOPHOSPHAMIDE TBI
NONMYELOABLATIVE/REDUCED INTENSITY
e.g.FLUDARABINE MELPHALAN /- CAMPATH

HIGH DOSE TREATMENT AND ALLOGRAFTING
PERSPECTIVES and QUESTIONS INDICATIONS
in ADULTS INDICATIONS in
CHILDREN SITUATION in INDIA
SITUATION in PAKISTAN
ALLOGRAFTING IN RIYADH

HIGH DOSE TREATMENT AND ALLOGRAFTING
DISCUSSION HIGH-DOSE TREATMENT AUT. PBPC -
adults - children ALLOGRAFTING - adults -
children

6
HIGH DOSE TREATMENT AND ALLOGRAFTING
QUESTIONS - IN DEVELOPING COUNTRY SETTING 1)
WHAT IS THE MORTALITY?

7
HIGH DOSE TREATMENT AND ALLOGRAFTING
QUESTIONS ctd. 2)WHAT DO YOU NEED TO DO IT?

8
HIGH DOSE TREATMENT AND ALLOGRAFTING
QUESTIONS ctd. 3) WHAT ARE THE INDICATIONS?(IF
ANY?) - in adults? - in children?

9
HIGH DOSE TREATMENT AND ALLOGRAFTING
QUESTIONS 4) IS IT A JUSTIFIABLE COST? - IN
ECONOMIC and HUMAN TERMS?

HIGH-DOSE TREATMENT
AUTOLOGOUS PBPC
  • EUROPE NORTH AMERICA MANY HOSPITALS

MORTALITY 1 2
NEEDS EXPERIENCED MEDICAL NURSING STAFF
SINGLE ROOMS BATHROOM and TOILET
INFRASTRUCTURE FOR COLLECTING CELLS
LAB FOR FREEZING CELLS

ALLOGRAFTING
  • AFFLUENT COUNTRIES FAR FEWER CENTRES
  • MORTALITY CORRELATES WITH AGE
  • FULL ALLOGRAFT 20 - 25
  • NON-MYELOABLATIVE 10 - 15

NEEDS EXPERIENCED MEDICAL NURSING STAFF
SINGLE ROOMS etc. PROBLEMS LACK OF HLA
IDENTICAL SIBLING DONORS ACUTE AND CHRONIC GRAFT
vs HOST DISEASE

HIGH-DOSE TREATMENT
AUTOLOGOUS PBPC
  • DIFFUSE LARGE B-CELL LYMPHOMA
  • MOST IMPORTANT PROGNOSTIC FACTOR
  • IS REMISSION STATUS AT TIME OF HDT
  • PERSON MUST BE IN REMISSION!
  • OTHERWISE NOT WORTH DOING
