We performed a retrospective analysis of DLBCL with breast involvement to compare the prognosis of primary breast lymphoma (PBL) to secondary breast lymphoma (SBL; especially in limited stage cases). We retrospectively reviewed records of 25 diffuse large B-cell lymphoma (DLBCL) patients with breast involvement who received chemotherapy between January 2000 and August 2012. We compared clinical features and prognosis among patients with PBL (n = 11), limited stage SBL (LSBL; n = 6), and advanced stage SBL (ASBL, n = 8). The PBL group had significantly lesser patients with breast tumours (BTs) > 5 cm than the SBL group (P = 0.02). After a median follow-up of 71.3 months, we observed significantly better 5-year overall survival (OS) in the PBL group (90.0%) than in the LSBL (33.3%, P = 0.01) group, but not for progression-free survival (PFS). Patients with BT > 5 cm had worse OS (P = 0.01) and PFS (P = 0.04) than those with BT ≤ 5 cm. PBL had a better prognosis than SBL among limited stage DLBCL.We aimed to demonstrate whether PET-CT can replace bone marrow biopsy in detecting bone marrow involvement in subtypes of lymphoma. In addition, we aimed to also reveal whether there is a difference between the mean survival of patients with bone marrow involvement via PET-CT or biopsy. A total of 276 newly diagnosed lymphoma patients who underwent bone marrow biopsy and PET-CT prior to the treatment were scanned retrospectively. Bone marrow biopsy was used as the standard method to investigate the presence of bone marrow involvement in PET-CT. The relationship between bone marrow involvement and mean survival was compared using both methods. Out of the 276 patients, bone marrow involvement was detected with PET-CT and with biopsy, respectively in 56 patients (20.2%) and in 78 patients (28.2%). In terms of PET-CT's accuracy with respect to revealing bone marrow involvement, the highest rates were achieved respectively in diffuse large B cell lymphoma (DLBCL) (87.4%) and Hodgkin lymphoma (HL) (77.7%). In both the PET-CT and bone marrow biopsy methods, Overall Survival (OS) was found to be significantly shorter in patients with involvement than in patients without involvement (P 0.001). PET-CT may replace bone marrow (BM) biopsy in detecting the bone marrow involvement in aggressive lymphoma subtypes such as DLBCL and HL. The presence of BM involvement at the time of diagnosis in both PET-CT and BM biopsy is associated with poor prognosis, and OS is short in this group.A primary immune deficiency disorder is often suspected in children with recurrent deep seated and fungal infections and those admitted to pediatric intensive care units. Chronic granulomatous disease (CGD) is inherited disorder leading to infections caused due to defective superoxide production. Cases referred for testing for a primary immunodeficiency disorder were tested for Dihydrorhodamine 123 (DHR) assay by flow cytometry and nitroblue tetrazolium dye (NBT) slide test. The unstimulated and stimulated samples were tested for oxidative burst activity which gives bright fluorescence due to formation of Rhodamine 123 on flow cytometry and blue formazan pigment in NBT slide test. The test results were reported in real time. From a total of 330 patients screened for chronic granulomatous disease using DHR and NBT slide test, 17 patients (5.1%) were found to have CGD. These included 12 boys and 5 girls. They presented with deep seated infections, recurrent and multiple abscess, recurrent pneumonia and granulomatous lymphadenitis. The causative organisms were Mycobacteriae, Staphylococcus, Burkholderia cepacia, Pseudomonas, Aspergillus and Cytomegalovirus. In 6 out of 17 positive cases family studies were carried out. On follow up five children succumbed to disease, two patients underwent allogeneic bone marrow transplant, the chimerism status was demonstrated by repeat DHR assay at day 50 post-transplant. Rest are in follow up under prophylactic antibiotics and supportive care. As facilities for molecular testing are not easily available for primary immuno deficiency disorders, flow cytometry based clinical laboratories can help to screen for some of the frequently suspected disorders like chronic granulomatous disease. This has aided in paediatric care in our centre.Growth differentiation factor 15 (GDF15) plays an important role in cancer pathophysiology and prognosis. However, limited studies analyzed its level and prognostic value in acute myeloid leukemia (AML) patients. This study included 56 adult AML patients. Serum GDF15 level was measured at diagnosis in all patients by enzyme-linked immunosorbent assay. https://www.selleckchem.com/products/aticaprant.html Remission and survival statuses were assessed at 90 days following treatment. GDF15 level was significantly higher in patients than in controls (P  less then  0.001). GDF15 level correlated positively with age (P  less then  0.001), hemoglobin level (P = 0.027), and platelet count (P = 0.024). High GDF15 above the median level was associated with inferior OS (P = 0.044) together with high platelet count (P = 0.006) and high bone marrow blast percent (P = 0.038). There was no statistically significant difference between patients with GDF15 above and below the median level regarding DFS (P = 0.881). On multivariate analysis for OS, GDF15 level was an independent risk factor (P = 0.047). In conclusion, serum GDF15 level is significantly elevated in AML patients and high GDF15 level is associated with inferior OS.Inherited polymorphic sequence variations in drug transport genes like ABCB1 impact a portion of patients with hematologic malignancies that show intrinsic or acquire resistance to treatment. Keeping in view inter-individual sensitivities for such drugs, we through this case-control study tested whether ABCB1 C3435T and G2677T polymorphisms have any influence on the risk and treatment response in patients with chronic myeloid leukemia (CML) and B-acute lymphoblastic leukemia (B-ALL). Genotyping for ABCB1 polymorphisms was performed by polymerase chain reaction-restriction fragment length polymorphism in 100 CML and 80 B-ALL patients along with 100 age and gender matched healthy controls. ABCB1 C3435T and G2677T polymorphism showed no association with CML. Genotype distribution revealed significant higher frequency of TT genotype for both SNPs in B-ALL cases and associated with increased B-ALL risk (OR 2.5, p = 0.04 for 3435TT; OR 2.4, p = 0.04 for 2677TT). There was no significant difference in genotype frequency of 3435C > T and 2677G > T among resistant and responsive groups for the two leukemia types.
