  • A 6-year retrospective cohort study was conducted among Thai hematologic malignancy (HM) patients receiving intensive chemotherapy. Of the 145 eligible patients receiving 893 chemotherapy sessions, 46.9% were female, median age was 52 years, and the most common HM diagnosis was diffuse large B-cell lymphoma (46.2%). Febrile neutropenia (FN) occurred in 14.9% of chemotherapy sessions with an incidence of 24.8 per 1,000 chemotherapy cycles per year. Independent factors associated with FN were receiving the first chemotherapy cycle [adjusted hazard ratio (aHR) 4.1], having hemoglobin ${\leq}100g/L$ (aHR 3.7) and platelet ${\leq}140,000/{\mu}L$ (aHR 2.7) on chemotherapy day and receiving acute myeloid leukemia regimens (aHR 20.8). Granulocyte colony stimulating factor was significantly associated with reduced rate of FN when given in those receiving CHOP regimen. With the median follow-up time of 16 months, the overall survival time was significantly longer in patients without FN than those with FN (61.7 vs. 20.8 months; p<0.001).

  • Purpose: To retrospectively analyze variability and clinical significance of serum ferritin levels in Chinese patients with hematologic malignancies. Materials and Methods: Serum ferritin were measured by radioimmunoassay, using a kit produced by the Beijing Institute of Atomic Energy. Patients with hematologic malignancies, and treated in the Department of Hematology in Nanjing First Hospital and fulfilled study criteria were recruited. Results: Of 473 patients with hematologic malignancies, 262 patients were diagnosed with acute leukemia, 131 with lymphoma and 80 with multiple myeloma. Serum ferritin levels of newly diagnosed and recurrent patients were significantly higher than those entering complete remission stage or in the control group (p<0.001). Conclusions: Serum ferritin lever in patients with hematologic malignancies at early stage and recurrent stage are significantly increased, so that detection and surveillance of changes of serum ferritin could be helpful in assessing conditions and prognosis of this patient cohort.

  • IL-18 production may enhance immune system defense against KG-1 cells ; NB4 cells, which are associated with good prognosis, do not produce IL-18. In this study, we treated KG-1 cells with IL-18 and used microarray technology to assess subsequent effects on gene expression. In UniGene-array of 7488 human genes, expression of 57 genes, including stress related genes, increased at least 2-fold, whereas expression of 48 genes decreased at least 2-fold. Following exogenous exposure of KG-1 cells to IL-18, expression of CRYGC, $NF{\kappa}BIA$ and NACA gene were monitored. The latter is a transcriptional coactivator potentiating c-Jun-mediated transcription.$NF{\kappa}BIA$ is an inhibitor of $NF{\kappa}B$, and affects growth regulation, apoptosis and hypoxic stress. Studies, such as this one, are beginning to clarify the differences between cells associated with good and bad cancer prognoses, which may ultimately assist in medical treatment for acute myeloid leukemia.

  • Traditionally, a positive bone scan shows single or multiple areas of increased uptake in the metastatic skeletal disease. The occurence of "cold" lytic-like or photon-deficient lesions in bone imaging is probably uncommon. Photon-deficient focus or cold lesion of the sternum was demonstrated on $^{99m}Tc-MDP$ bone imaging in 2 individuals with acute myloid leukemia and primary hepatoma, respectively.

  • Background: Recent studies have shown that 3-deazaneplanocin A (DZNep), a well-known histone methyltransferase inhibitor, disrupts polycomb-repressive complex 2 (PRC2), and induces apoptosis, while inhibiting proliferation and metastasis, in cancer cells, including acute myeloid leukemia, breast cancer and glioblastoma. However, little is known about effects of DZNep on ovarian cancer cells. Materials and Methods: We here therefore studied DZNep-treated A2780 ovarian cancer cells in vitro. Proliferation of ovarian cancer cells under treatment of DZNep was assessed by MTT and apoptosis by flow cytometry. Cell wound healing was applied to detect the migration. Finally, we used q-PCR to assess the migration-related gene, E-cadherin. Results: DZNep could inhibit the proliferation of A2780 and induce apoptosis Furthermore, it inhibited migration and increased the expression of E-cadherin (P<0.05). Conclusion: DZNep is a promising therapeutic agent for ovarian cancer cells, with potential to inhibite proliferation, induce apoptosis and decrease migration.

  • A 44 year-old male patient was undergoing diagnosis and therapy for acute myelogenous leukemia (AML, M2). On physical examination a thyroid mass was palpated in the left lower lobe. He had palpitation and intolerance to heat. Thyroid function tests revealed hyperthyroidism; T3: 150ng/dl (N:60-90), fT4: 2.26 ng/dl (N:0.70-1.80), TSH: 0.01 ulU/ml (N:0.25-5.00). Ultrasonography demonstrated a hypoechoic mass with scattered calcifications measuring 2.55 2.03 3.64 cm in size. F-18 FDG camera-based PET scan performed as a follow-up study of AML revealed a focal increased uptake in the left neck, where an autonomous nodule was detected on Tc-99m thyroid scan. After the diagnosis of toxic autonomous nodule, Goetz disease, he underwent surgical nodulectomy. Microscopically, the nodule contained follicular proliferation with degenerative change but without evidence of thyroid carcinoma. Focal uptake in autonomous thyroid nodules is due to increased glycolysis within the nodules.

  • Hemosiderosis is characterized by the deposition of excess iron in body tissues. The choroid plexus is an important part of the central nervous system that can be the primary site of iron overload. T2*-weighted gradient echo (GRE) sequence provides high sensitivity for demonstrating cerebral microhemorrhagic foci and iron deposition. In the present study, we describe the case of a 15-year-old boy with acute lymphoblastic leukemia, in whom repeated transfusion led to iron accumulation in the brain. GRE sequence effectively demonstrated hemosiderin deposition in the choroid plexus.

  • The present study has been undertaken to characterize availability of camellia(Camellia japonica L.) as a medicinal plant with antineoplastic and chemosensitizing activities. The crude extracts from fresn camellia flower, young leaves and nutraceutical tea of camellia leaf and flower buds were evaluated on their potential activities against various human cancer cells and multidrug resistance to cancer cells in vitro. The range of cytotoxicity displayed from 120$\mu\textrm{g}$/mL to 200$\mu\textrm{g}$/mL. Catemix 1(CT-1) mixed with camellia and green tea showed high toxicity(respectively IC$\sub$50/=l16$\mu\textrm{g}$/mL, 129$\mu\textrm{g}$/mL) against AML-2/WT, acute myelogenous leukemia cell and MCF-7, brest adenocarcinoma pleual effusion cell. Generally camellia tea mixed with green tea showed higher cytotoxicity than the other camellia teas mixed with some herbs(CH). Methanol extract of steamed camellia tea and roasted camellia tea had a chemosensitizing effect to reverse Pgp-mediated MDR. In addition, camellia flower tea of insignificant cytotoxicity, chemosensitizing effect were increased remarkably chemosensitizing effect in mixed flower tea with some herbs.
