Translation and validation of the Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) version 4 quality of life instrument into Arabic language.

BACKGROUND: Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) has been translated from English into several languages. Currently, there is no validated translation of FACT-BMT in Arabic. Here, we are reporting the first Arabic translation and validation of the FACT-BMT. METHODS: The study was approved by the Institutional Research Advisory Council. The Arabic translation followed the standard Functional Assessment of Chronic Illness Therapy (FACIT.org) translation methodology (with permission). Arabic FACT-BMT (50- items) was statistically validated. Cronbach's alpha for internal consistency, Spearman's rank correlation coefficients method for Inter-scale correlations and Principal Component Analysis for factorial construct validity was used. RESULTS: One hundred and eight consecutive relapsed /refractory lymphoma patients who underwent high dose chemotherapy and autologous stem cell transplant were enrolled. There were 68 males (63%) and 40 females (37%) with a median age of 29 years (range 14-62). After Arabic questionnaire pre-testing (Cronbach's alpha 0.744), the study included 108 patients. Cronbach's alpha for the entire FACT-BMT indicated an excellent internal consistency (0.90); range (0.67 to 0.91). Cronbach's alpha for sub-groups of social (0.78), emotional (0.67) and functional wellbeing was (0.88). Cronbach's alpha for bone marrow transplant (0.81), FACT-General (0.89), and FACT- Trial Outcome Index (TOI); (0.91) also revealed excellent internal consistency. Patients had high scores in all domains of quality of life, indicating that most patients were leading a normal life. This translation of FACT-BMT in Arabic was reviewed and approved for submission by the FACIT.org. CONCLUSIONS: Our data reports the first translated, validated and approved Arabic version of FACT-BMT. This will help large numbers of Arabic speaking patients undergoing stem cell/bone marrow transplantation, across the globe.

Outcome analysis of high-dose chemotherapy and autologous stem cell transplantation in adolescent and young adults with relapsed or refractory Hodgkin lymphoma.

High-dose chemotherapy (HDC) and autologous stem cell transplantation (auto-SCT) can salvage many patients with relapsed or refractory Hodgkin's lymphoma (HL). We are reporting the outcome of HDC auto-SCT and the impact of 21 prognostic factors in relapsed and refractory adolescent (14-21 years) and young adult (>21-30 years) (AYA) HL patients. We used Fine and Gray's competing risk analysis method and regression model for outcome analysis. From 1996 to 2013, 290 consecutive patients with biopsy-proven HL underwent HDC auto-SCT for relapsed/refractory HL; 216 patients (74.5 %) were AYA at the time of auto-SCT. Male/female were equal, median age at auto-SCT was 22.4 years, and there were 94 adolescent (43.5 %) and 122 young adults (56.5 %). There was refractory disease in 121 (56 %) patients, relapsed in 95 (44 %). Median follow-up was 72.6 months. The Kaplan-Meier method estimated that 5-year overall survival is 62.7 % (adolescents (63.5 %), young adults (62 %)) and event-free survival was 51.3 %. Five-year cumulative incidence of disease-specific death (DS-death) is 33 % and that of DS-event is 45 %. For DS-death, the multivariate analysis identified complete remission (CR) duration of <12 months (hazard ratio (HR) 3.61, P = 0.0009), no CR after salvage (HR: 3.93, P = 0.0002), and nodular sclerosis pathology (HR 3.3, P = 0.016) and positive B symptoms (HR 2, P = 0.028) as negative factors. For DS-event, CR duration of <12 months (HR 1.88, P = 0.02), no CR after salvage (HR 3.47, P = 0.000005) and nodular sclerosis pathology (HR 1.88, P = 0.02) were found significant. The Kaplan-Meier method estimated overall survival (OS) at 36 months with 0-2:3:4 factors being 93.6:54:21 %, respectively (P value <0.001). Kaplan-Meier estimated event-free survival (EFS) at 36 months with 0-1:2:3 factors being 84.6:65:31 %, respectively (P value <0.001). Clinically, adolescents have similar outcomes as young adults.
