{INTRODUCTION: Myelodysplastic syndrome (MDS) is an uncommon disorder accounting for less than 5% of hematopoietic neoplasia in childhood. Although many therapeutic options have been attempted for pediatric MDS including immunosuppressive therapy, epigenetic modifying agents, high-dose chemotherapy, and hematopoietic growth factors, but still hematopoietic stem cell transplant (HSCT) is the only curative therapy for those patients. We described the outcome of pediatric patients with MDS and the factors affecting the overall survival (OS) and event free survival (EFS). METHODS: This is a retrospective descriptive study included newly diagnosed patients with MDS who presented to Children Cancer Hospital Egypt (CCHE-57357), between July 2007 and December 2015, and were followed till June 2017. Patients with congenital (inherited) marrow failure syndromes were excluded. All patients were reviewed for the diagnostic criteria according the WHO classification. Wait and see approach was adopted for patients with Refractory Cytopenia of Childhood (RCC) who had normal karyotype and were transfusion independent. HSCT was offered to patients who had HLA matched family donors after HLA typing. They received myeloablative conditioning therapy followed by stem cell infusion.Systemic chemotherapy (AML-like) was given before transplant for those with RAEB and RAEB-T / MRD-AML. RESULTS: Forty four patients were analyzed with median age at diagnosis of 6.5 years. Primary MDS was encountered in 40 patients (91%), 2 patients were Down syndrome (4.5%), and the remaining 2 patients (4.5%) were secondary MDS (therapy-related). Eighteen patients (40.9%) had RCC, 19 (43.2%) had RAEB, and 7 patients (15.9%) had RAEB-T / MRD-AML. Cytogenetic abnormalities were observed in 23 patients (52.3%), in which monosomy 7 was the commonest abnormality observed (25%), while normal karyotype was found in 19 patients (43.2%). Allogeneic HSCT from HLA matched donors was performed in 9/44 patients. The mean time to transplant since diagnosis was 8.6 months (ranging from 6 months to 15 months). All patients received myeloablative conditioning regimen in the form of Busulfan / Cyclophosphamide followed by stem cell infusion. The Average CD34+ count was 3.57×106 /Kg recipient weight. The bone marrow harvest was the source of the stem cells in 7/9 patients, while peripheral blood was used for the 2 other patients. With median follow up duration of 14.25 months (ranging from 0 - 105 months), the 2-year overall survival (OS) and event-free survival (EFS) for the whole cohort were 43.3% (±15.68) and 33.8% (±14.896), respectively, and for the transplanted patients were 75% (±29.988) and 60% (±35.672), respectively. Univariate analysis showed improved 2 years-OS and EFS in patients who underwent HSCT as compared to those who didn’t; yet it was not statistically significant mostly due to low number of patients (75% versus 35.4% for OS

Abstract

PURPOSE: We determined the effect of 5α-reductase inhibitors on disease reclassification in men with prostate cancer optimally selected for active surveillance.

MATERIALS AND METHODS: In this retrospective review we identified 635 patients on active surveillance between 2002 and 2015. Patients with favorable cancer features on repeat biopsy, defined as absent Gleason upgrading, were included in the cohort. Patients were stratified by those who did or did not receive finasteride or dutasteride within 1 year of diagnosis. The primary end point was grade reclassification, defined as any increase in Gleason score or predominant Gleason pattern on subsequent biopsy. This was assessed by multivariable Cox proportional hazards regression analysis.

RESULTS: At diagnosis 371 patients met study inclusion criteria, of whom 70 (19%) were started on 5α-reductase inhibitors within 12 months. Median time on active surveillance was 53 vs 35 months in men on vs not on 5α-reductase inhibitors (p <0.01). Men on 5α-reductase inhibitors received them for a median of 23 months (IQR 6-37). On actuarial analysis there was no significant difference in grade reclassification for 5α-reductase inhibitor use in patients overall or in the very low/low risk subset. The overall percent of patients who experienced grade reclassification was similar at 13% vs 14% (p = 0.75). After adjusting for baseline clinicopathological features 5α-reductase inhibitors were not significantly associated with grade reclassification (HR 0.80, 95% CI 0.31-1.80, p = 0.62). Furthermore, no difference in adverse features on radical prostatectomy specimens was observed in treated patients (p = 0.36).

CONCLUSIONS: Among our cohort of men on active surveillance 5α-reductase inhibitor use was not associated with a significant difference in grade reclassification with time.

Abstract

PURPOSE: To determine the effect of 5α-reductase inhibitors (5-ARI) on disease reclassification in men with prostate cancer optimally selected for active surveillance (AS).

MATERIALS AND METHODS: A retrospective review identified 635 patients on AS between 2002-2015. Patients with favorable cancer features on repeat biopsy, defined as absence of Gleason upgrading, were included in the cohort. Patients were stratified by those who did or did not receive finasteride/dutasteride within 1 year of diagnosis. The primary endpoint was grade reclassification, defined as any increase in Gleason score or predominant Gleason pattern on a subsequent biopsy, and was assessed by multivariable Cox proportional hazards regression analysis.

RESULTS: At diagnosis, 371 patients met inclusion criteria, of whom 70 (19%) were started on 5-ARIs within 12 months. Median time on AS was 53 vs. 35 months for men on 5-ARI vs. not on 5-ARI, respectively (p<0.01). Men on 5-ARI received 5-ARIs for a median of 23 months (IQR 6-37). On actuarial analysis, there was no significant difference in grade reclassification with 5-ARI use in patients overall or in the very low/low-risk subset. The overall percentage of patients experiencing grade reclassification was similar (13% vs. 14%, p=0.75). After adjusting for baseline clinicopathologic features, 5-ARI use was not significantly associated with grade reclassification (HR 0.80, CI 0.31-1.80; p=0.62). Furthermore, no difference in adverse features on radical prostatectomy specimens was observed in treated patients (p=0.36).

CONCLUSIONS: Among our cohort of men on AS, 5-ARI use was not associated with a significant difference in grade reclassification over time.
