    Abstract:
    e19054 Background: The addition of BV to cytotoxic agent(s) prolonged survival for non-Sq NSCLC patients (pts). However, there is no definitive evidence for the cytotoxic agent(s) plus BV is superior to the cytotoxic agent(s) alone for elderly non-Sq NSCLC. We conducted the feasibility study of PEM plus BV as the first-line treatment for elderly advanced or recurrent non-Sq NSCLC. Methods: Major eligibility and exclusion criteria were followings; chemotherapy-naïve; unfit for bolus combination chemotherapy; stage III/IV or relapsed non-Sq NSCLC; age≥70; PS 0-1; no evidence of brain metastasis; no history of hemoptysis and irradiation for thorax. PEM (500 mg/m 2 ) and BV (15 mg/kg) were administrated intravenously on day 1 every 3 weeks. The primary endpoint was toxicity and the secondary endpoints were objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and the percentage of pts who completed more than 3 cycles. Results: From November 2010 to April 2012, total 12 pts were enrolled. Patients characteristics were following; male/female=6/6; Median age (range) 78 (72-81); histology was all adenocarcinoma; activating EGFR mutation no/yes/unknown=9/2/1; stage IIIB/IV/recurrence=2/8/2; ECOG PS 0/1=6/6; smoking history yes/no=6/6. Severe toxicities (Grade 3≥) were leukopenia (25%), neutropenia (25%), anemia (8%), thrombocytopenia (8%), febrile neutropenia (8%), anorexia (8%), hypertension (8%), fatigue (8%), nausea (8%), and perforation (colon) (8%). No dose-limiting toxicity and treatment-related death was occurred. Three patients achieved PR and the ORR was 25%. The median PFS and OS were 5.6 months (mo) (95% C.I. 1.1-7.9 mo) and 10.3 mo (95% C.I. 6.9-15.6 mo) in 11 evaluated pts, respectively. The 1-year survival rate was 49% (95% C.I. 12-79%). Seven of 12 pts (58%) received more than 3 cycles. Conclusions: PEM plus BV as first-line treatment for elderly non-Sq NSCLC was well tolerable and promising. Clinical trial information: UMIN000004263.

    Clinical endpoint
    A single case of a male stage-IV lung cancer patient is reported, there were exon 19 deletion mutations in the epidermal growth factor receptor (EGFR). Intra-, and extrapulmonary, lesions occurred a month after gefitinib and erlotinib applications. Patient was then switched to the first-line chemotherapy program. Both types of lesions significantly improved four weeks after a combined therapy of pemetrexed disodium + carboplatin+ bevacizumab (7.5mg/Kg d1), two weeks after continuous therapy with pemetrexed disodium + bevacizumab (7.5mg/ Kg d1). Short-term efficacy was assessed as PR, without significant adverse effects, reflecting program efficacy and good tolerance.

    Background: Infections and nutritional deficiencies are the most common causes of the leucopenia and neutropenia. In this study, we aimed to find the incidence of vitamin B12 deficiency in patients with leukopenia and neutropenia secondary to infection.Methods: Between September 2018 and December 2018, patients who were referred to Diyarbakır Children Hospital's Pediatric Hematology and Oncology Clinic for leukopenia and/ or neutropenia were thought to develop secondary to infection retrospectively evaluated.Results: Of the 60 patients that evaluated, 23(38.3%) were female and 37(61.7%) were male. The mean age±SD was 4.75±4.5 years. Severe neutropenia was detected in 5(8.3%), moderate neutropenia in 31(51.7%) and mild neutropenia in 17(28.3%) patients. Neutrophil counts were within normal limits in 7(11.7%) patients. When vitamin B12 levels were examined, 17(28.3%) patients had B12 deficiency.Conclusions: Investigation and treatment of vitamin B12 deficiency in patients with leukopenia and neutropenia may shorten the duration of cytopenia and prevent the development of secondary complications.

    Neutropenia (or granulocytopenia) is a depression of the absolute neutrophil count to less than 1,500/mm3. Leukopenia is a related term, denoting the depression of the total leukocyte count. Although neutropenia is the most frequent cause ofleukopenia, a marked lymphocytopenia can depress the total leukocyte count in the "penic" range with a normal neutrophil count. However, a severe leukopenia always implies neutropenia.

    To estimate the prevalence and clinical significance of leukopenia and neutropenia in patients with chronic hepatits C, to analyze the impact of different regimens of antiviral therapy by standart or induction doses of pegylated interferon alpha-2a (PegIFNalpha-2a) to optimize curative measures.24 patients with genotype 1 HCV and different therapeutic regimens of PegIFNalpha-2a were investigated with analysis of kinetics and prevalence of leukopenia and neutropenia.On an average 66,7% patients meet neutropenia during antiviral therapy, and 37,5% and 16,7% among them was the moderate and severe grade accordingly. The major prevalence of leukopenia and neutropenia was evidenced between 12 and 24 weeks of antiviral therapy, the marked severity of neutropenia was noted.It was no correlation between the prevalence of leukopenia and neutropenia and the induction treatment regimens of PegIFNalpha-2a; the tendency for more severity in patients with advanced fibrosis and cirrhosis was detected. It was no infection complications during the therapy observed so it may be provided with full doses of PegIFNalpha-2a in case of mild and moderate grades of leukopenia and neutropenia.

    Leukopenia is an abnormal reduction of circulating white blood cells, especially the granulocytes. The term leukopenia is often used interchangeably with neutropenia. It may result from reduced production of white blood cells or increased utilization and destruction, or both. Infection, drugs, malignancy, megaloblastosis, hypersplenism and immunoneutropenia are responsible for most cases of neutropenia. Primary neutropenia is very rare. Sometimes, particularly in children, primary neutropenia is hereditary and may be associated with other developmental defects. The major danger of neutropenia is the risk of infection. Management requires identification of the cause and effective antimicrobial therapy, especially when serious systemic infection is present.

    Blood counts of 372 Yemenite Jews of all ages were reviewed in order to clarify the epidemiology of benign leukopenia. Twenty-one percent of the total leukocyte counts were below 5.0 x 10(3) cells/mm3. Neutropenia < 2.0 x 10(3) was present in 15.4% of the blood counts, significantly lowering the average neutrophil count in the population. There was no significant variation in the prevalence of neutropenia with age. In contrast, the average lymphocyte and erythrocyte counts were normal. We conclude that leukopenia among Yemenite Jews should be defined as neutropenia rather than leukopenia, and that the phenomenon is only half as common as was previously noted. Since the prevalence of neutropenia remains constant across all age-groups, in immigrants as well as among the Israeli-born, it is unlikely to be an acquired condition.

    bjective:To investigate the protective action of HLCJ on the leukopenia and neutropenia induced by cytoxan(CTX)in mice. Method: Models of mice with leukopenia and neutropenia here were made by injecting with CTX(100 mg/kg)for 3 days,meanwhile,these mice were treated with HLCJ and the dynamic changes of 1eukocyte and neutrophil in these mice were observed.Results:HLCJ(32g/kg,16g/kg) administrated for 8 days could improve leukopenia and neutropenia induced by CTX in mice.Oral administration of HLCJ (32g/kg,16g/kg,8g/kg) for l2 days could increase the decreased number 0f 1eukocytes and neutrophil in CTX treated mice. Conclusion: HlCJ has significant protective effect on leukopenia and neutropenia induced by cytoxan in mice.

    Leukopenia is a common finding in the outpatient setting. It typically occurs because of a significant reduction in neutrophils, which comprise 50% to 70% of circulating leukocytes. Neutropenia is defined as an absolute neutrophil count (ANC) of less than 1,500/mcL. Neutropenia is classified by whether it is transient or chronic. Chronic neutropenia can be further described as extrinsic or intrinsic. Extrinsic causes are varied. Intrinsic causes can include impaired proliferation and maturation of myeloid progenitor cells in the bone marrow. Assessment of patients with neutropenia should be guided by the severity on presentation. The duration of leukopenia and the clinical status of the patient also should be considered. Some patients with neutropenia can develop life-threatening bacterial infections. In neutropenic patients, the risk of febrile neutropenia should be assessed systematically. Patients with febrile neutropenia should undergo treatment with antibiotics. Other treatments are aimed at management of the underlying cause of neutropenia.

    We studied the effects of Cepharanthin (CEP) on bone marrow suppression induced by chemotherapy in 18 primary lung cancer patients (14 NSCLC, 4 SCLC). NSCLC patients received IP (IFM+CDDP) therapy and SCLC patients received ION (IFM+VCR+ACNU) therapy. For the control, we chose the first course and we administered CEP (1 mg/kg) during the second course. The rate of leukopenia and neutropenia was significantly lower during the CEP course than during the control (p less than 0.01). The recovery rate (at 3 weeks) of leukopenia and neutropenia was significantly higher during the CEP course than during the control (p less than 0.05). But, obvious effects of CEP for lymphopenia and thrombocytopenia were not obtained. Side effects by CEP were not observed in this study. These data suggest that the large dose of CEP contributes to the prevention of leukopenia, especially neutropenia, in patients who receive a sufficient amount of anticancer drugs.
