1Presentation,management,and outcome of newly diagnosed glioblastoma in elderly patients显示文摘OBJECT: Optimum management for elderly patients with newly diagnosed glioblastoma(GBM) in the temozolomide(TMZ) era is not well defined.The object of this study was to clarify outcomes in this population.METHODS: The authors retrospectively reviewed 105 consecutive cases involving elderly patients(age ≥ 65 years) with newly diagnosed GBM who were treated at the Mayo Clinic between 2003 and 2008.RESULTS: The patients' median age was 74 years(range 66-87 years),and the median Karnofsky Performance Status(KPS) score was 80(range 40-90).Half of the patients underwent biopsy and half underwent resection.Patients with deep-seated lesions(19 patients [18%]) or multifocal lesions(34 patients [32%]) were more likely to have biopsy than resection(p = 0.0001 and 0.0009,respectively).New persistent neurological deficits developed in 7 patients(6.7%).Postoperative hemorrhage occurred in 6 patients(5.7%),all of whom underwent biopsy.Complete follow-up data regarding adjuvant treatment was available in 84 patients.Forty-one(49%) were treated with chemotherapy(mostly TMZ) and radiation therapy(RT),and 23(27%) with RT alone.Nineteen(23%) received only palliative care after surgery(more common with biopsy,p = 0.03).Chemotherapy complications occurred in 28.6%(Grade 3 or 4 hematological complications in 11.9%).The median values for progression-free survival(PFS) and overall survival(OS) were 3.5 and 5.5 months.In a multivariate analysis,younger age(p = 0.03,risk ratio [RR] 0.34,95% CI 0.13-0.89),single lesion(p = 0.02,RR 0.51,95% CI 0.30-0.89),resection(p = 0.04,RR 0.54,95% CI 0.31-0.94),and adjuvant treatment(p = 0.0001,RR 0.24,95% CI 0.11-0.49) were associated with better OS.Only adjuvant treatment was significantly associated with prolonged PFS(p = 0.0007,RR 0.27,95% CI 0.13-0.57).With combined therapy with resection,RT,and chemotherapy,the median PFS and OS were 8 and 12.5 months,respectively.CONCLUSIONS: The prognosis for GBM worsens with increasing age in elderly patients.With important risks,resection and adjuvant treatment are associated with prolonged survival.Although selection bias cannot be excluded in this retrospective study,advanced age alone should not necessarily preclude optimal resection followed by adjuvant radiochemotherapy.Tanaka S Meyer FB Buckner JC Uhm JH Yan ES Parney IF 2013中国神经肿瘤杂志2013,11,1:4

4Oral polymorphonuclear neutrophil characteristics in relation to oral health: a cross-sectional, observational clinical study显示文摘Polymorphonuclear neutrophils(PMNs) have a major role in the innate immune system. However, little is known about PMN contribution in relation to oral health. The objective of this study was to investigate the numbers and functional characteristics of oral PMNs(o PMNs) compared with circulatory PMNs(c PMNs). Oral rinse and venous blood samples were obtained from 268 systemically and orally healthy volunteers in a cross-sectional observational study. PMN counts, cell cycle analysis and cellular activation state were investigated. Also, reactive oxygen species(ROS) production was analyzed, with and without bacterial stimulation(Fusobacterium nucleatum). In males, 1.2 × 10~6± 1.0 × 10~6 oPMNs were collected, and showed a tendency to correlate with the levels of gingival bleeding(r = 0.215, P = 0.008). Comparable o PMNs counts were found among females(1.0 × 10~6± 0.7 × 10~6). More late-stage apoptotic/necrotic cells were found among the o PMNs(53.1%) compared with the c PMNs(8.5%; Po0.001). Without additional stimulation, o PMNs were more activated than c PMNs, as indicated by higher expression of CD11 b, CD63 and CD66 b, and higher constitutive ROS levels(Po0.001). Notably, in response to bacterial stimulation, o PMNs released comparable ROS levels as c PMNs(P = 0.042). In conclusion, this study provides data on viable o PMNs showing high levels of activation in orally and systemically healthy individuals, free of apparent caries lesions and periodontal disease. These data suggests that although the o PMNs are in a more mature stage of their life cycle compared with the c PMNs, o PMNs are still responsive to stimulation, which indicates their functional potential and possible contribution to a healthy oral ecosystem.Patrick Rijkschroeff Ineke DC Jansen Fridus A van der Weijden Bart IF Keijser Bruno G Loos Elena A Nicu 2016International Journal of Oral Science2016,8,3:2
