Duval/CIBMTR Score for AML Survival

Description

Calculates the Duval/CIBMTR score to predict 3-year overall survival in patients with active Acute Myelogenous Leukemia (AML) undergoing hematopoietic cell transplantation (HCT). The score stratifies patients based on disease status, cytogenetics, donor match, circulating blasts, and performance status.

Usage

duval_cibmtr_aml_survival(disease_group, cytogenetics, hla_match,
                          circulating_blasts, karnofsky_score)

Arguments

disease_group	Numeric (0 or 1). Disease status group. 0: Primary induction failure OR Duration of first complete remission > 6 months. 1: Duration of first complete remission < 6 months (or relapse within 6 months).
cytogenetics	Numeric (0 or 1). Cytogenetic risk group. 0: Good or Intermediate. 1: Poor.
hla_match	Numeric (0 or 1). Donor HLA match type. 0: HLA-identical sibling or well-matched/partially-matched unrelated donor. 1: Mismatched unrelated donor or related other than HLA-identical sibling. (+2 points).
circulating_blasts	Numeric (0 or 1). Presence of circulating blasts at the time of transplant. (1 = Present, +1 point).
karnofsky_score	Numeric (0 or 1). Karnofsky Performance Status (KPS) or Lansky scale. 0: 90-100. 1: < 90. (+1 point).

Value

A list containing:

Duval_CIBMTR_Score	The calculated score (Range 0-6).
Estimated_3_Year_Survival	The predicted 3-year overall survival probability.

Examples

# Example 1: Good Prognosis
# CR1 > 6mo (0), Good Cyto (0), Matched Sib (0), No Blasts (0), KPS 90 (0)
# Score = 0
duval_cibmtr_aml_survival(0, 0, 0, 0, 0)

# Example 2: Poor Prognosis
# CR1 < 6mo (1), Poor Cyto (1), Mismatched Donor (1 -> +2pts), Blasts Present (1), KPS 80 (1)
# Score = 1 + 1 + 2 + 1 + 1 = 6
