RESUMEN

HLA alleles are representative of ethnicities and may play important roles in predisposition to hematological disorders. We analyzed DNA samples for HLA-A, -B, -C, -DRB1, and -DQB1 loci, from 1550 patients and 4450 potential related donors by PCR-SSO (Polymerase chain reaction sequence-specific oligonucleotides) and estimated allele frequencies in donors and patients from 1550 families who underwent bone marrow transplantation (BMT) in Egypt. We also studied the association between HLA allele frequencies and incidence of acute myeloid leukemia, acute lymphoblastic leukemia, and severe aplastic anemia. The most frequently observed HLA class I alleles were HLA- A*01:01 (16.9%), A*02:01 (16.1%), B*41:01 (8.7%), B*49:01 (7.3%), C*06:02 (25.1%), and C*07:01 (25.1%), and the most frequently observed class II alleles were HLA-DRB1*11:01 (11.8%), DRB1*03:01 (11.6%), DQB1*03:01 (27.5%), and DQB1*05:01 (18.9%). The most frequently observed haplotypes were A*33:01~B*14:02 ~ DRB1*01:02 (2.35%) and A*01:01~B*52:01~DRB1*15:01 (2.11%). HLA-DRB1*07:01 was associated with higher AML odds (OR, 1.26; 95% CI, 1.02-1.55; p = 0.030). Only HLA-B38 antigen showed a trend towards increased odds of ALL (OR, 1.52; 95% CI, 1.00-2.30; p = 0.049) HLA-A*02:01, -B*14:02, and -DRB1*15:01 were associated with higher odds of SAA (A*02:01: OR, 1.35; 95% CI, 1.07-1.70; p = 0.010; B*14:02: OR, 1.43; 95% CI, 1.06-1.93; p = 0.020; DRB1*15:01: OR, 1.32; 95% CI, 1.07-1.64; p = 0.011). This study provides estimates of HLA allele and haplotype frequencies and their association with hematological disorders in an Egyptian population.

RESUMEN

BACKGROUND: Different prophylactic protocols are available for preventing graft-versus-host disease (GVHD) after matched sibling donor (MSD) allogeneic hematopoietic cell transplantation (allo-HCT). This study aimed to compare the effectiveness of post-transplantation cyclophosphamide plus cyclosporine A (PT-CY/CSA) versus methotrexate plus CSA (MTX/CSA) as GVHD prophylaxis protocols in adult acute myeloid leukemia (AML) patients who received peripheral blood stem cells (PBSC) from fully matched donors. METHODS: The 1-year outcomes of 89 patients treated with PT-CY/CSA and 90 patients treated with MTX/CSA who had MSD allo-HCT for AML using unmanipulated mobilized PBSC were examined and compared. RESULTS: The cumulative incidence of acute GVHD at 100 days was considerably lower in the PT-CY/CSA group (4% vs 19.3%, p = 0.002), however there were no statistically significant difference in the cumulative incidence of chronic GVHD at 1-year (19.6% vs 37.4%, p = 0.053). Significant delays in neutrophil and platelet engraftments were reported in the PT-CY/CSA group (17 vs 12 days) and (13 vs 12 days), respectively (p < 0.001). The cumulative incidences of relapse (19.1% vs 13.7%, p = 0.470), overall survival (79.1% vs 77.3%, p = 0.986), non-relapse mortality (16.5% vs 16.8%, p = 0.837), and the GVHD and relapse-free survival (GRFS) (53.7% vs 46.6%, p = 0.478) did not differ statistically at 1-year. CONCLUSION: PT-CY/CSA demonstrated a significant decrease in the rate of acute GVHD. However, it was associated with engraftment delay.

RESUMEN

The aim of the current study was to assess the prognostic value of circulating tumor cells (CTCs) and their related markers at different points of chemotherapy regimens in metastatic breast cancer (MBC) patients. The impact of CTCs on progression free survival (PFS) and overall survival (OS) rates were also assessed. Peripheral blood samples were obtained from 66 female patients with MBC at different time intervals for evaluation of CTCs by flow cytometry (FC). cytokeratin 19 (CK19), mammaglobin, prolactin inducible peptide (PIP), aldehyde dehydrogenase 1 (ALDH1) and human chorionic gonadotropin (hCG) were also assessed by qRT-PCR. Analysis of different CTC levels (at 4, 5, and 6 cells/7 ml), showed statistically significant values at 4 cells/7 ml blood. The presence of baseline CTCs < 4 cells/7 ml, associated significantly with higher PFS (P value = 0.03). Patients showing a decrease in the CTCs level after treatment had significantly prolonged median PFS and OS rates compared to those whose CTCs level increased (P = 0.007 and P = 0.014; respectively). Mammaglobin, CK19, PIP, ALDH1 and hCG expression did not affect PFS or OS. However, patients with CTCs ≥ 4 at diagnosis had higher rates of progression compared to those with CTCs < 4 (1.9 times, P = 0.07), and who metastasized before 4 years showed a worse decrease outcomes (they were 2.4 time more progressed than those who metastasized after 4 years; P = 0.029). CTCs could be an independent prognostic and predictive biomarker for MBC patients' outcomes. Although none of the assessed genes (mammaglobin, CK19, PIP, ALDH1 and hCG) showed correlation with PFS or OS rates, further studies on a larger number of patients are required to validate the current results.

RESUMEN

BACKGROUND: Graft-versus-host disease (GVHD) is one of the most severe complications in patients with acute myeloid leukemia (AML) who underwent allogenic hematopoietic stem cell transplantation (HSCT). This study addressed the effectiveness and safety outcomes of high dose post-transplant cyclophosphamide (PT-CY) followed by cyclosporine A (CSA) as a GVHD prophylaxis protocol. PATIENTS AND METHODS: From January 2019 to March 2021, AML patients who underwent HSCT, and received high-dose PT-CY followed by CSA were prospectively recruited, assessed, and followed up for one-year post-transplantation (PT). The cumulative incidences of both acute GVHD (aGVHD) at 100 days PT, and chronic GVHD (cGVHD) at one-year PT were assessed. RESULTS: This study included 52 patients. The cumulative incidence (95% CIs) of aGVHD was 2.3% (0.3 - 15.4%), while the cumulative incidence of cGVHD was 23.2% (12.2-41.5%). The cumulative incidence of relapse and non-relapse mortality were 15.6%, and 7.9%, respectively. The median duration to reach neutrophil and platelet engraftment was 17 and 13 days, respectively. The overall, progression-free, and GVHD-free/relapse-free survival rates (95% CIs) were 89.6% (76.6 - 95.6%), 77.7% (62.1-87.5%), and 58.2% (41.6 - 71.7%) respectively. The cumulative incidences of the main transplant-related complications were; neutropenic sepsis (48.3%), cytomegalovirus reactivation (21.7%), pneumonia (13.8%), hemorrhagic cystitis (17.8%), septic shock (4.9%), and CSA toxicity (48.9%). CONCLUSION: PT-CY followed by CSA was associated with low cumulative incidences of both aGVHD and cGVHD without increase in either the relapse or transplant-related complications; so, considered as a promising protocol to be widely applied in the settings of HLA-matched donors.

RESUMEN

BACKGROUND AND OBJECTIVES: Post-transplant cyclophosphamide (PTCy) has shown promising results with low rates of severe graft-versus-host-disease (GVHD), either alone or combined with conventional immunosuppression (CIS). However, studies comparing PTCy with CIS as a GVHD prophylaxis are scarce. The study aimed to determine the rates of GVHD and survival outcomes for patients undergoing peripheral blood stem cell transplant (PBSCT) from HLA-matched related donors (MRD) receiving PTCy-based GVHD prophylaxis and compare these outcomes with those of patients receiving methotrexate (MTX) and cyclosporine-A (CsA) as a GVHD prophylaxis. PATIENTS AND METHODS: Seventy-five patients with advanced hematologic malignancies who underwent MRD allogeneic hematopoietic cell transplantation (allo-HCT) were analyzed prospectively. These patients received PTCy and CSA as a GVHD prophylaxis (therapeutic group) and their outcomes were compared with those of 75 retrospectively collected patients who received methotrexate and CsA as a GVHD prophylaxis (historical group) from the same two transplant centers. RESULTS: The median recipient age was significantly lower in the MTX/CsA group at 28 years compared to 34 years in the PTCy/CSA group. Peripheral blood was the only graft source used. All patients had a complete MRD, with two patients having a one-antigen mismatched related donor within the PTCy/CsA group. The 1-year cumulative incidence (CI) of chronic GVHD was 13.4% with PTCy/CsA and 38.6% with MTX/CsA (P = .001). Acute GVHD CI across all grades did not differ between the groups, with 10.7% for PTCy/CsA and 14.7% for MTX/CsA (P = .46). At two years, the overall survival (OS) (54.4% vs 67.2%, P = 0.282), disease-free survival (DFS) (54.1% vs 66.1%, P = 0.358), relapse rates (27.4% vs 20.1%, P = 0.245), and non-relapse mortality (NRM) (29.3% vs 25%, P = 0.904) did not differ between PTCy/CsA and MTX/CsA, respectively. CONCLUSION: PTCy-based GVHD prophylaxis in MRD transplant is feasible and leads to lower chronic GVHD rates without causing a significantly different risk of relapse or survival than MTX/CsA. More extensive studies are needed to confirm our results.

RESUMEN

The objective of this study is to describe a simple surgical procedure for management of acquired total nasopharyngeal obstruction in adults. Five patients were diagnosed as having complete nasopharyngeal obstruction over a 3-year period. Three patients previously underwent uvulopalatoplasty, while for the remaining two it was due to pharyngoscleroma. In all the patients, nasopharyngeal obstruction was at the level of the inferior edge of the soft palate. Two of the post-uvulopalatoplasty patients had recurrent obstruction after scar excision and topical application of mitomycin-C without stenting. All the patients were treated surgically by creation of a new anatomical nasopharyngeal isthmus and stenting it by nasopharyngeal airway for 6 months. All the patients experienced satisfactory results and good tolerability to airway placement. The nasopharyngeal airway can counteract the inevitable scar contraction of the new nasopharyngeal isthmus after surgical correction and maintain its patency.

RESUMEN

BACKGROUND: Prognostication of AML patients depends on association of genetic and epigenetic abnormalities. We aimed to evaluate the frequency and prognostic significance of Additional Sex comb's Like1 (ASXL1), Isocitrate Dehydrogenase (IDH) and Casitas B- lineage Lymphoma (CBL) mutations in AML assessing their association with different cytogenetic risk category. METHODS: We used High Resolution Melting (HRM) technology that detects small differences in PCR amplified sequences by direct melting using EvaGreen saturating dye to analyze epigenetic mutations in 70 denovo AML patients. RESULTS: Median age of AML patients was 39.5 years (18-75). ASXL1, IDH and CBL mutations were detected in 14 (20%), 10 (14%) and 5 (7%) patients, respectively. Mean age of ASXL1 and IDH mutants vs. wild type was 35.9±14.6 years and 42.9±14.4 years (p=0.114) and 46.7±15.2 years vs. 40.6±14.5 years (p=0.290), respectively. AML cytogenetic risk groups included low (25/70, 36%), intermediate (33/70, 47%) and high-risk (12/70, 17%). Nine/14 (64%) ASXL1 and 8/10 (80%) IDH mutants were classified as intermediate risk and 9 ASXL1 positive (64%) were adolescent and young adults (AYA). Overall survival (OS) of mutant ASXL1 vs. wild type was 1.1 years (95% CI 0.83-1.4) vs. 1.9 years (95% CI 0.71-7.51), respectively (p=0.056). OS of mutant IDH vs. wild type was 1.25 years (95% CI 0.85-1.6) vs. 1.8 years (95% CI 1.2-6.7), respectively (p=0.020). In intermediate risk cytogenetic group, ASXL1 and IDH mutants had shorter OS than wild type; 1.1 years (95% CI 0.97-1.2) vs. 2.1 years (95% CI 0.14-10.8) (p=0.002) and 1.8 years (95% CI 0.69-3.15) vs. 2.3 years (95% CI 1.1-5.5) (p=0.05), respectively. CONCLUSION: ASXL1 and IDH mutations occur at a high incidence among young Egyptian AML patients with intermediate risk cytogenetics and confer a poorer outcome. Integration of mutations into risk profiling may predict outcome and impact therapeutic approach of young AML patient with uncertain prognosis.

RESUMEN

The nasal contact point may act as a trigger point or peripheral enhancer in patients with chronic daily headaches. A total of 42 patients had unsatisfactory response to medical treatment for chronic daily headache with radiologic evidence of nasal contact point. Of them, 12 (28.5%) patients were positive for the local anesthetic test. Those patients were operated upon to separate this contact by either septoplasties or submucous resections with or without partial turbinectomies. The mean headache frequency was reduced from 22 to 7 days/month. The mean headache severity was reduced from 5.6 to 2.4. Eight (19%) patients became completely free from headache and its medications, six (75%) of them were positive for local anesthetic test. The patients were satisfied with postoperative monotherapy, or headache severity and frequency could be tolerated without medications in 26 (62%) patients. There was no improvement in seven (16.6%) patients and only one patient (2%) became worse. The overall satisfaction was 83 and 81% for positive and negative anesthetic tests, respectively. The average monthly medication cost was reduced from $85 to 32. Nasal contact point surgery for chronic daily headache patients can satisfy them compared to previously unsatisfactory medications. Nasal contact point may contribute to potentiating or triggering chronic daily headache.

RESUMEN

The objective of this study was to evaluate the benefits of intra-operative ultrasonic guidance in the management of isolated nasal bone fractures. A prospective, randomized, controlled, double blinded study was designed. Sixty-eight patients who had isolated fracture nose were treated by either a simple closed reduction or by ultrasound-guided reduction (34 patients each) with a follow up for an average of 4.5 and 5.5 months, respectively. Post-traumatic and post-reduction nasal profiles were compared (by blinded photographer), and patient's satisfaction was analyzed after reduction in both groups. We used Student's t test for independent groups to compare between the average patient's scores. The average patient's nasal profile score for closed reduction group was 2.31. Thirteen patients (40.6%) had scored 3, 16 (50%) had scored 2, and three (9.4%) patients had scored 1. The average patient's nasal profile score for ultrasonic assisted group was 2.72. Twenty-four patients (75%) had scored 3, 7 (22%) had scored 2, and one (3%) patient had scored 1. The average patient's satisfaction score for closed reduction was 2.62. Twenty-four patients (75%) had scored 3, 4 (12.5%) patients had scored 2, and 4 (12.5%) patients had scored 1. The average patient's satisfaction score for ultrasonic assisted group was 2.78. Twenty-six patients (81%) scored 3, 5 (16%) patients scored 2, and one (3%) patient scored 1. Patients undergoing ultrasonic nasal bone reduction scored significantly better nasal profile scores than patients undergoing simple closed reduction, on the other hand, patient satisfaction scores had no significant difference between both groups. Treating nasal bone fractures with the assistance of intra-operative ultrasound resulted in a significantly better nasal profile appearance, than treating it by simple closed reduction.

RESUMEN

BACKGROUND: COVID-19 viral pandemic caused many mortalities in cancer patients especially those with hematological malignancies. The immunological response to COVID-19 infection is responsible for the outcome of cases whether mild, severe or critical. CASE PRESENTATION: Two cases presented with moderate COVID-19 viral infection, concomitant with acute myeloid leukemia and T acute lymphoblastic leukemia, respectively. Surprisingly, after the administration of COVID-19 supportive therapy, the cases showed disease remission after a follow-up period of 12 and 5 months, respectively. Additionally, the blast cells dropped to only 3% and 0% in the bone marrow aspirates of those two cases, respectively, after it was 30% in both cases at diagnosis. CONCLUSION: The immune response that emerged against COVID-19 infection could potentially produce anti-tumor immunity in some patients, or the virus may act as an oncolytic virus. However, further investigations are required to explain this phenomenon, which may help in finding a possible new targeted therapy for these cases.

RESUMEN

To assess the prognostic role of different inflammatory indices on the outcome of cancer patients with COVID-19. Sixty-two adults and 22 pediatric cancer patients with COVID-19 infection were assessed for the prognostic value of certain inflammatory indices including the neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), platelet to lymphocyte ratio (PLR), derived NLR (dNLR), systemic inflammation index (SII), mean platelet volume to platelet ratio (MPR), C-reactive protein to lymphocyte ratio (CRP/L), aggregate index of systemic inflammation (AISI), systemic inflammation response index (SIRI), and neutrophil to lymphocyte, platelet ratio (NLPR). Data were correlated to patients' outcome regarding ICU admission, and incidence of mortality. Increased CRP/L ratio in adult COVID-19 cancer patients was significantly associated with inferior survival [152 (19-2253) in non-survivors, compared to 27.4 (0.8-681) in survivors (P = 0.033)]. It achieved a sensitivity (60%) and a specificity (90.2%) at a cut-off 152, while it achieved a sensitivity of 60% and specificity 95.1% at a cut-off 252 (AUC 0.795, P = 0.033). When combining both CRP/L and NLPR for the prediction of poor outcome in adult cancer patients with COVID19, the sensitivity increased to 80% and the specificity was 70.7% (AUC 0.805, P = 0.027). Increased incidence of ICU admission in pediatric cancer patients associated significantly with the severity of covid19 infection, decreased mean corpuscular hemoglobin (MCH) < 28.3, increased red cell distribution width (RDW) > 16, lymphopenia < 1.04, pseudo Pelger-Huet appearance, and PLR < 196.4 (P = 0.004, P = 0.040, P = 0.029, P = 0. 0.039, P = 0.050, and P = 0.040; respectively). The mean corpuscular volume (MCV), MCH, and RDW could be useful prognostic markers for poor outcome in COVID-19 pediatric cancer patients (P < 0.05 for all). Increased both CRP/L and NLPR associated significantly with poor survival in adult COVID-19 cancer patients, while PLR associated significantly with ICU admission in pediatric COVID-19 cancer patients.

RESUMEN

BACKGROUND: Acute myeloid leukemia (AML) evolves from neoplastic transformation of stem cell disease termed "leukemia stem cells" (LSCs). An unsatisfactory response to AML therapy is determined by the presence of minimal residual disease (MRD). The predominance of LSCs might anticipate sustained MRD results. The present study aimed to demonstrate the effect of LSCs on MRD at induction days 14 and 28 on overall survival (OS) and disease-free survival (DFS) and to compare LSC expression with MRD status. PATIENTS AND METHODS: A total of 84 patients with de novo adult AML underwent testing using LSC panels for CD38/CD123/CD34/CD45 and CD90/CD133/CD45/CD33 and different regular MRD panels. RESULTS: At day 14 after induction, the high expression of CD123 and CD133 had adverse effects on both OS and DFS (P = .004 and P ≤ .001 and P ≤ .001 and P ≤ .001, respectively). Greater expression of CD34+/CD38-/CD123+ resulted in unfavorable OS and DFS (P ≤ .001 for both). Both CD34+/CD38-/CD123+ and CD34-/CD38+/CD123+ expression at day 14 after induction had an adverse effect on DFS only (P < .001 and P = .029, respectively). On multivariate analysis, CD133 expression and MRD status were independent prognostic parameters (hazard ratio [HR], 2.3; 95% confidence interval [CI], 1.2-4.4; P = .015; and HR, 2.9; 95% CI, 1.0-7.9; P = .041). At day 28 after induction, MRD and increased CD123+/CD34-, CD34+/CD38-/CD123+, CD133+/CD33- expression were associated with inferior OS (P = .016, P = .0035, P = .0.002, and P = .002, respectively). MRD and high expression of CD34+CD123+, CD133+/CD33-, CD34+/CD38-/CD123+ were associated with inferior DFS (P < .001, P = .002, P < .001, P < .001, respectively). On multivariate analysis, only CD133+/CD33- expression was the independent prognostic factor (HR, 3.1; 95% CI, 1.5-6.7; P = .003). CONCLUSIONS: Estimation of LSC expression is a sensitive indicator of the response to therapy in adult patients with AML and might be a better prognosticator than the findings from regular MRD panels.

RESUMEN

BACKGROUND: Core binding factor acute myeloid leukemia (CBF-AML) encodes 2 recurrent cytogenetic abnormalities, t(8;21) and inv(16), which carries an overall good prognosis. However, some patients will develop a relapse. We sought define the unfavorable group of CBF-AML by analysis of (c-KIT and FLT3-ITD) and to correlate them with treatment outcome. PATIENTS AND METHODS: We performed a prospective study of 70 patients with CBF-AML diagnosed and managed at the medical oncology department of the (National Cancer Institute), Cairo University, with analysis of c-KIT and FLT3 mutations. All patients had received "3 + 7" induction, followed by 3 to 4 courses of high-dose cytarabine consolidation. The institutional review board approved the present study. RESULTS: The median patient age was 31 years (range, 18-60 years), with a male/female ratio of 4:3. Of the 70 patients, 42 (60%) had t(8;21) and 28 had inv(16) (40%). c-KIT mutations (exons 8 and 17) were detected in 10 of 52 tested patients, and FLT3-ITD was detected in 3 of 70 patients. Patients with inv(16) experienced more lymphadenopathy and splenomegaly, had a higher median initial leukocyte count. Hepatitis C antibody positivity (8 of 42) was exclusively present in patients with t(8;21). The median overall survival (OS) was 19.5 months, and the median disease-free survival (DFS) was not reached. Patients with inv(16) had near-significant (P = .07) better DFS than patients with t(8;21). c-KIT mutations had no significant effect on OS or DFS. However, reverse tyrosine kinase mutations had a negative effect on DFS but not OS (P = .04). CONCLUSION: CBF-AML with reverse tyrosine kinase mutation conveys a worse prognosis. Hepatitis C virus antibody positivity might be associated with t(8;21) AML and inv(16) with more extramedullary disease.

RESUMEN

Hematopoietic Stem Cell Transplantation (HSCT) is the only potentially curative treatment option for the hematologic complications that occur in patients with Fanconi anemia (FA). In this study, we present a retrospective multicenter analysis from the Eastern Mediterranean Blood and Marrow Transplantation Group (EMBMT) of matched related donor HSCT for FA in adolescents and adults transplanted between 1988 and 2015. Forty-five patients received HSCT with a median age at transplant of 18 years, the interquartile range (IQR) (15-23.5); 25 (55.6%) patients were females and 20 (44.4%) were males. Conditioning regimen was fludarabine-based in 29 (64.4%) patients, irradiation-based in five (11.1%) patients, and the remaining patients received other combinations. Indication for HSCT was bone marrow failure in 39 (86.7%) and myelodysplastic syndrome in six (13.3%) patients. Stem cell source was bone marrow in 22 (48.9%), peripheral blood in 20 (44.4%), umbilical cord blood in one (2.2%), and combination of bone marrow and cord blood in two (4.4%) patients. Twenty-seven (60%) patients engrafted and five (11.1%) had primary engraftment failure. The median time to neutrophil engraftment was 14 days (range 10-21 days); median time for platelet engraftment was 17 days (10-33 days). The probability of developing grade II-IV acute GVHD for all patients was 7.0% and chronic GVHD 36.6%. No new malignancies were reported. The OS probability was 53.6% (95% CI, 38.3-68.9%) with a median follow-up of 13 months (95% CI, 1-240). Our HLA-matched related HSCT results in AYA patients with FA compare favorably with other reported international registry data.

RESUMEN

OBJECTIVE: To determine whether premedication with 45 mg of oral dextromethorphan (DM) given 90 minutes prior to nasal surgery decreases postoperative pain and consequently reduces opioid administration and also, if it reduces the pain of pack removal. METHODS: This was a prospective, double blind, randomized, controlled study carried out from January 2007 to March 2008 at Al-Moosa General Hospital, Al-Ahsa, Saudi Arabia, in which 38 patients received oral DM (age 28 +/- 11 years), and 38 patients received placebos (age 26 +/- 10 years). Postoperative pain was assessed using a visual analog scale, and a pain score of > or -5 was treated by a rescue bolus dose of morphine sulfate 2 mg every 10 minutes in the post-anesthesia care unit (PACU) and by one gm of paracetamol in the surgical ward until the score became <5. Pain was also assessed during pack removal. RESULTS: The placebo group had a higher pain score in the PACU, and hence a higher morphine consumption than the DM group (7.3 mg +/- 2.6 versus 4.6 mg +/- 1.2, p=0.03). Pain score in the surgical ward was also higher in the placebo group at 4, 8, 12, and 24 hours, but this was insignificant, and was insignificantly lower only at 18 hours (p=0.26). The placebo group had a higher pain score at pack removal than the DM group (7.8 +/- 11 versus 3.5 +/- 15, p=0.004). CONCLUSION: Preemptive medication with DM reduces opioid administration in the early postoperative period and during pack removal.

RESUMEN

BACKGROUND: Early blast clearance to induction chemotherapy in acute myeloid leukemia (AML) is an important prognostic indicator of treatment outcome in addition to genetics and molecular genetics. We evaluated the prognostic value of bone marrow aspiration (BMA) at day 14 (D14) and impact on outcome to asses the timing of a second induction. PATIENTS AND METHODS: This retrospective study included 303 adult AML patients managed at the National Cancer Institute, Cairo University, from the beginning of 2010 to the end of 2014. RESULTS: Median age was 34 years (range, 18-67 years). Sixty-six percent had early blast clearance with < 5% blasts and 34% had ≥ 5% blasts at BMA D14; 38 patients died early during or shortly after induction. Initial blast load (bone marrow and peripheral blood) and initial platelet count were significantly higher in those with disease that did not respond to therapy compared to those whose disease did respond to therapy at D14 (P < .001, .035, and .006, respectively). The median disease-free survival for early blast clearance at D14 was 18.5 months, versus 18.7 months for those with late response to therapy (day 28), and was only 1.3 months for patients who received immediate second-line therapy on the basis of BMA D14 (P < .001). The median overall survival for early blast clearance was 13.6 months, versus 7.2 months for those with late response to therapy, and only 1.3 months for patients who received immediate second-line therapy on the basis of BMA D14 (P < .001). CONCLUSION: BMA D14 has a significant prognostic impact on the therapeutic outcome of AML patients (complete remission, disease-free survival, and overall survival); however, a second induction in patients with BMA D14 blasts > 5% should be delayed until neutrophil recovery to minimize death in aplasia.

RESUMEN

JAK2, CALR, MPL and triple-negative mutational status has a direct impact on symptom severity and disease burden assessed by MPN10 score in myeloproliferative neoplasms (MPNs). Among 93 patients; median MPN10 score was 48 (5-76) in JAK2 mutants versus 25 (4-80) in JAK2 negative (p < .001); 22.5 (4-65) in CALR mutants versus 35 (5-80) in CALR negative (p < .050) and 21 (10-48) in triple negative versus 40 (4-80) in JAK2/CALR/MPL mutants (p < .001). At three years, progression free and overall survival of JAK2-positive versus JAK2-negative patients were 62% versus 100% (p < .001); 85% versus 100% (p = .011) and were 100% versus 78% (p = .067); 100% versus 92% (p = .197) in CALR-positive versus CALR-negative patients and 100% versus 75% (p = .004); 100% versus 90% (p = .015) in triple negative versus mutant patients, respectively. MPN10 score in association with driver gene mutations can be used as a predictor of survival in MPN patients.

RESUMEN

Granulocytic Sarcoma (GS) is a rare condition with a wide list of differential diagnosis and debatable guidelines of treatment in different cancer centers. Most of literature recommended systemic chemotherapy with or without radiation therapy and small role of surgery. One of the rarest sites for myeloid sarcoma is hard palate, which usually worsen the quality of life of the patient due to difficulty in feeding, drinking and speaking. We are reporting a case of hard palatine fistula caused by granulocytic sarcoma, in which we tried to get local control of disease with 3 dimension conformal radiation therapy 3DCRT and surgery with systemic control with chemotherapy using recommendation of multidisciplinary team and targeting mainly patient quality of life.

RESUMEN

Malignancy is the second most common cause of mortality in the reproductive period and it complicates up to one out of every 1000 pregnancies. When cancer is diagnosed during pregnancy, the management approach must take into consideration both the mother and her fetus. Hematologic cancers diagnosed in pregnancy are not common, resulting in paucity of randomized controlled trials. Diagnosis of such malignancies may be missed or delayed, as their symptoms are similar to those encountered during normal pregnancy. Also, many imaging studies may be hazardous during pregnancy. Management of these malignancies during pregnancy induces many treatment-related risks for mother and baby and should consider patient's preferences for pregnancy continuation. In this article, hematologic malignancies diagnosed in pregnant patients including acute leukemias, chronic myeloid leukemia, lymphomas, multiple myeloma and myeloproliferative neoplasms, will be reviewed, including diagnostic and management strategies and their impact on the pregnant patient and the developing fetus.

RESUMEN

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) from a geno-identical matched sibling (MSD) is one of the most successful therapies in patients with non-malignant hematological disorders. This study included 273 patients with severe aplastic anemia (SAA), 152 patients with B-Thalassemia major (BTM), 31 patients with Fanconi's anemia (FA), 20 patients with congenital immunodeficiency diseases (ID), and 13 patients with inherited metabolic disorders (IMD) allografted from a MSD. In SAA, the 8-year overall survival (OS) of the whole group patients was 74%. OS was significantly better in patients conditioned with fludarabine and cyclophosphamide (Flu/Cy) than in those who received cyclophosphamide and antithymocyte globulin (Cy/ATG) (p = 0.021). Acute graft-versus-host disease (aGVHD) grade II-IV occurred in 15% while chronic GVHD (cGVHD) occurred in 28%. In BTM, the 12-year disease-free survival (DFS) of the whole group of BTM patients was 72.4%. DFS was 74% for peripheral blood stem cell (PBSC) group compared to 64% in the BM stem cell group. The incidence of graft rejection was significantly lower in patients who received PBSC than in those who received BM (9% vs 25%) (p = 0.036). AGVHD grade II-IV and cGVHD occurred in 15% and 12% of the whole group of BTM patients respectively. In FA, the 5-year OS was 64.5%. Graft rejection occurred in 10% of patients. Grade II-IV aGVHD occurred in 16% while cGVHD occurred in 4%. In ID, the 5-year OS was 62%. Graft rejection occurred in two (10%) patients. Three patients (15%) developed grade II-IV aGVHD, 2 of them progressed to secondary cGVHD. In IMD, OS was 46% at 5 years. Graft rejection occurred in 8% of patients. AGVHD grade II-IV occurred in 15% while cGVHD occurred in 14%. In conclusion, Allo-HSCT provides a higher DFS rate over conventional therapies for patients with non-malignant hematological disorders with prolonged survival.
