The effects of vascular endothelial growth factor (VEGF) blockade on the vascular biology of human tumors are not known. Here we show here that a single infusion of the VEGF-specific antibody bevacizumab decreases tumor perfusion, vascular volume, microvascular density, interstitial fluid pressure and the number of viable, circulating endothelial and progenitor cells, and increases the fraction of vessels with pericyte coverage in rectal carcinoma patients. These data indicate that VEGF blockade has a direct and rapid antivascular effect in human tumors.VEGF has a crucial role in physiological and pathological angiogenesis 1-3 . Although VEGF blockade, alone or in combination with cytotoxic therapies, is being tested in a number of
Purpose We evaluated the impact of early integrated palliative care (PC) in patients with newly diagnosed lung and GI cancer. Patients and Methods We randomly assigned patients with newly diagnosed incurable lung or noncolorectal GI cancer to receive either early integrated PC and oncology care (n = 175) or usual care (n = 175) between May 2011 and July 2015. Patients who were assigned to the intervention met with a PC clinician at least once per month until death, whereas those who received usual care consulted a PC clinician upon request. The primary end point was change in quality of life (QOL) from baseline to week 12, per scoring by the Functional Assessment of Cancer Therapy-General scale. Secondary end points included change in QOL from baseline to week 24, change in depression per the Patient Health Questionnaire-9, and differences in end-of-life communication. Results Intervention patients ( v usual care) reported greater improvement in QOL from baseline to week 24 (1.59 v −3.40; P = .010) but not week 12 (0.39 v −1.13; P = .339). Intervention patients also reported lower depression at week 24, controlling for baseline scores (adjusted mean difference, −1.17; 95% CI, −2.33 to −0.01; P = .048). Intervention effects varied by cancer type, such that intervention patients with lung cancer reported improvements in QOL and depression at 12 and 24 weeks, whereas usual care patients with lung cancer reported deterioration. Patients with GI cancers in both study groups reported improvements in QOL and mood by week 12. Intervention patients versus usual care patients were more likely to discuss their wishes with their oncologist if they were dying (30.2% v 14.5%; P = .004). Conclusion For patients with newly diagnosed incurable cancers, early integrated PC improved QOL and other salient outcomes, with differential effects by cancer type. Early integrated PC may be most effective if targeted to the specific needs of each patient population.
Addressing methodological problems in the development of existing scales for measuring alexithymia, this study reports the development of a new self-report scale. The Toronto Alexithymia Scale (TAS) was devised with concern for theoretical congruence with the alexithymia construct, independence of social desirability response bias, and internal consistency. Initially, 41 items were administered to 542 college students. Twenty-six items meeting preestablished psychometric guidelines were retained. Factor analysis yielded four interpretable factors, all consistent with the construct. The scale demonstrated adequate split-half and test-retest reliability, and scores were not significantly associated with age, education, and socioeconomic status. These preliminary results suggest that the TAS may be used as a clinical screening device with psychiatric and general medical patient populations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
