Acute Promyelocytic Leukemia With PML-RARA, t(15;17)
Conditions
Brief summary
This clinical trial studies how well simplified patient care strategy works in decreasing early death in patients with acute promyelocytic leukemia. Implementing simplified acute promyelocytic leukemia guidelines along with support from acute promyelocytic leukemia experts may decrease deaths and improve survival.
Detailed description
PRIMARY OBJECTIVES: I. To evaluate if the proposed patient care strategy, that includes use of simplified guidelines along with acute promyelocytic leukemia (APL) expert support, decreases the one-month induction mortality rate from 30% to under 15%. SECONDARY OBJECTIVES: I. To assess the overall survival 1 year after accrual is completed. II. To assess incidence and severity of differentiation syndrome. III. To correlate outcomes with time to initiation of all-trans retinoic acid (ATRA) from diagnosis or suspicion of diagnosis. IV. To compare outcomes between academic and community centers separately. V. To evaluate factors associated with outcome. OUTLINE: Patients receive standard of care treatment for APL. Patients and doctors regularly discuss with an APL expert to identify and mange treatment. After diagnosis, patients are followed up for 1 year.

Eligibility
Inclusion criteria
* Confirmed to have a diagnosis of APL, which is defined as: * Positive t(15:17) by fluorescence in situ hybridization (FISH) or conventional karyotype * Positive promyelocytic leukemia/retinoic acid receptor PML/RAR alpha by polymerase chain reaction (PCR) * Patients must accept treatment and supportive care guidelines * Referrals must be made as early as possible but no later than 5 calendar days after ATRA therapy is initiated; consent can be obtained up till day 7 or earlier * Co-management can be started as soon as referral is made including weekends; the physician at the outlying facility should make every effort to call the APL expert at the first suspicion of APL
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| One-month Mortality Rate | Assessed at one month | Proportion of patients died within one month from the first date of induction therapy. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Survival Rate at One Year | Assessed at one year | Overall survival is defined as the time from the first date of induction therapy to death or date last known alive. Proportion of patients alive at one year was estimated using the method of Kaplan and Meier. |
| One-month Survival Rate by Lead Academic Sites and Community Sites | Assessed at one month | Proportion of patients who are alive at one month since the first date of induction therapy by lead academic sites and community sites |
| Differentiation Syndrome Rate | Assessed up to 1 year | The proportion of patients with differentiation syndrome (measured based on the CTC version 4.0) will be evaluated. |
| Association Between One-month Mortality Rate and Time From Diagnosis to Initiation of All-trans Retinoic Acid (ATRA) | Assessed at one month | The time from diagnosis and initiation of ATRA will be assessed and dichotomized as "short' vs. "long" using the median value. One-month mortality rate will be compared in these two groups (short vs. long) using the Fisher's exact test. |
| Association Between One-month Survival and Baseline Factors | Assessed at baseline and one month | The associations between one-month survival and baseline factors will be evaluated. |
