However, the role of these factors remains unclear. The aims of this study were to evaluate the prognostic significance of plasma fibrinogen concentration and platelet count, as well as to determine the overall survival of NSCLC patients with brain metastases. A total of 275 NSCLC patients with brain metastasis were enrolled into this study. Univariate analysis showed that high plasma fibrinogen concentration was associated with age ≥ 65 years(P = 0.011), smoking status(P = 0.009), intracranial symptoms(P = 0.022), clinical T category(P = 0.010), clinical N category(P = 0.003), increased partial thromboplastin time(P < 0.001), and platelet count(P < 0.001). Patients with low plasma fibrinogen concentration demonstrated longer overall survival compared with those with high plasma fibrinogen concentration(median, 17.3 months versus 11.1 months; P ≤ 0.001). A similar result was observed for platelet counts(median, 16.3 months versus 11.4 months; P = 0.004). Multivariate analysis showed that both plasma fibrinogen concentration and platelet count were independent prognostic factors for NSCLC with brain metastases(R2 = 1.698, P < 0.001 and R2 = 1.699, P < 0.001, respectively). Our results suggest that high plasma fibrinogen concentration and platelet count indicate poor prognosis for NSCLC patients with brain metastases. Thus, these two biomarkers might be independent prognostic predictors for this subgroup of NSCLC patients.展开更多

Methods： Between 1995 and 2002, 53 patients underwent resection of both primary non-small cell lung cancer and the associated single brain metastasis. There were 33 men and 20 women with a mean age of 57 years （range, 32-85 years）. At the time of diagnosis, 42 patients experienced lung cancer related symptoms, whereas 11 patients experienced brain metastases-related symptoms. 42 patients had received thoracic surgery first, and 11 patients had undergone neurosurgery or radiosurgery first. Pneumonectomy was performed in 9 out of 42 patients （21.4%）, lobectomies in 30 （71.4%）, and wedge resection in 3 （7.2%）. 48 patients （90.5%） underwent complete lymphadenectomy. 35 patients underwent brain metastasectomy. 18 underwent SRS. Results： There was no postoperative mortality and severe complications after either lung or brain surgery. Histology showed 34 adenocarcinomas, 16 squamous cell carcinomas, and 3 large cell lung cancers. 15 patients （28.3%） had no evidence of lymph node metastases （No）, 20 patients （37.7%） had hilar metastases （N1）, and 18 patients （34%） had mediastinal metastases （N2）. The 1-, 2-, 3- and 5-year overall survival rates were 49%, 19%, 10%, and 5%, respectively. The corresponding data for neurosurgery group were 55%, 17%, 11%, and 6%, respectively. The median survival time was 13 months. For SRS group the corresponding data were 44.8%, 20.9% 10.5%, and 2%, respectively. The median survival time was 14 months. The differences between the two groups were not significant （P〉0.05）. In lymph node negative patients （No）, the overall 5-year survival rate was 10%, as compared with a 1% survival rate in patients with lymph node metastases （N1-2）. The difference was significant （P〈0,01）. For adenocarcinomas, the 5-year survival rate was 5%. The correspondent data for squamous cell lung cancers was 3%. The difference was not significant （P〉0.05）. Conclusion： Although the overall survival rate for patients who have brain metastases from NSCLC is poor, surgical resection or radiosurgery may be beneficial in a select group of patients with synchronous brain metastases and lung cancer without lymph node metastases.展开更多

The contribution gives an overview updating developments of small-molecule, nonpeptide ligands at a selection of peptide and chemokine receptors, expressed in neurons and microglia of the brain, regarding the last five years. Orexin 1 and orexin 2 receptors (OX1R;OX2R) and neuropeptide Y1 and Y2 receptors (NPY1R, NPY2R) were chosen as representatives of Class A neuropeptide receptors, chemokine receptor CX3C (CX3CR1) as Class A, protein-activated receptor, highly expressed in activated microglia, and corticotropin releasing factor receptor 1 (CRFR1) as representative Class B1 receptor. Structural differences between binding domains and their endogenous ligands as well as parallel expression in different types of cells and generally low density of these receptors in brain tissue are factors making the search for selective and sensitive ligands more difficult than for classical GPCR receptors. Main progress in ligand development is observed for NPY receptor antagonists and orexin receptor antagonists. For orexin receptors, search for suitable ligands can be supported with modelling approaches, as recently the complete molecular structure of these receptors is available. Small molecules, binding at CRFR1, as for other Class B1 receptor ligands, in PET and investigations of pharmacodynamics revealed rather allosteric binding modes, although, the complete crystal structure of CRFR1 as prototype of Class B1 provides, hitherto, improved possibilities for understanding binding mechanisms. Highly specific as a marker of microglia among?the GPCRs, CX3CR1 is focused as target of PET during inflammation of brain and spinal cord.展开更多

In this article, an overview is given about tracers currently available and lead structures of potential PET probes for detection of?β-amyloid (Aβ), tau protein, α-synuclein, constitutive (PrPc) and infectious isoforms (PrPsc) of prions (proteinaceous infectious particles) as imaging targets. Whereas the styrylpyridine derivative florbetapir, approved for clinical applications, the stilbene derivative florbetaben and the benzoxazole derivative BF227 show high affinity binding to Aβ, preclinical investigations promise improved pharmacokinetics for benzoimidazothiazoles, aryloxazoles and benzofuran derivatives. Tau protein imaging based clinically, presently, on the pyridine-pyridoindole T807 has got new incentives following identification of a series of pyrrolopyridine quinolines and pharmacokinetic improvements of fluoropropoxy quinolines including for instance THK-5351. The pyridine isoquinoline MK6240 is involved now in clinical trials. Most forward-looking efforts apply to small molecule ligands of α-synuclein, which are expected to permit a breakthrough in differential diagnostics of Parkinson-related dementia and Lewy body diseases. However, at the moment the proposed lead structures are in affinity and blood brain barrier delivery properties below the possibilities of Aβ?and tau protein ligands. This is the case also for potential tracers of prion proteins.展开更多

Icotinib is a new type of oral epidermal growth factor receptor(EGFR) tyrosine kinase inhibitor(TKI) used in the treatment of advanced NSCLC. The aim of this study was to evaluate the efficacy of icotinib in NSCLC patients with brain metastasis.Methods This study reviewed records of 51 NSCLC patients with brain metastases who took icotinib 125 mg, 3 times a day. Response rate, progression free survival, and overall survival were analyzed. SPSS software version 17.0 was used for univariate analysis, and Cox regression analysis to analyze factors affecting survival. Results Thirty-six cases had partial response, 6 cases had stable disease, and 10 cases had progressive disease. In 31 cases, EGFR gene mutation test were performed. EGFR was mutated in 26 cases and was with wild-type in 5 cases. In patients with EGFR mutations, 23 patients responded to icotinib [the disease control rate(DCR) was 88.5%], significantly higher than in patients with wild-type EGFR(1 patient, DCR 20%)(P = 0.005). The overall median progression-free survival(PFS) was 7.6 months. PFS was longer in the patients with EGFR mutations than in those with wild type EGFR(7.8 months vs 1.2 months, P = 0.03). The overall median overall survival(OS) time was 10.7 months. OS was longer in patients with EGFR mutations than in those with wild type EGFR(15.1 months vs 6.7 months, P = 0.003). The main side effects of the treatment were skin rash and diarrhea; no stage 3 or 4 toxic effects occurred. Univariate analysis demonstrated that OS was related to sex, Eastern Cooperative Oncology Group performance status(ECOG PS), smoking history, and EGFR mutation. Multivariate analysis showed that OS was independently related to sex, ECOG PS, and EGFR mutations.Conclusion Icotinib has a favorable effect on NSCLC patients with brain metastases harboring EGFR mutations. Icotinib can be a new choice of treatment for brain metastases in patients with NSCLC harboring EGFR mutations.展开更多
