Well-regulated epidermal homeostasis depends on the function of different classes of factors, such as transcription regulators and receptors. Alterations in this homeostatic balance may lead to the ...development of cutaneous squamous tumorigenesis. The homeobox transcription factor DLX3 is determinant for a p53-dependent regulation of epidermal differentiation and modulates skin carcinogenesis. The maintenance of skin homeostasis also involves the action of neurotrophins (NTs) and their receptors, Trk and CD271. While Trk receptor overexpression is a hallmark of cancer, there are conflicting data on CD271 expression and function in cutaneous SCC (cSCC). Previous studies have reported NT receptors expression in head and neck SSC (HNSCC). We show that CD271 is expressed at low levels in primary cSCC cells and the number of CD271+ cells correlates with cell cohesion in SCC spheroids. In normal epidermis, CD271 is expressed in proliferative progenitor cells and DLX3 in terminally differentiated keratinocytes. Brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3) increase DLX3 expression. In the absence of a functional BDNF receptor TrkB in keratinocytes, we hypothesize that the BDNF-dependent DLX3 response could be mediated via CD271. Altogether, our results support a putative CD271-DLX3 connection in keratinocytes, which might be crucial to preventing squamous skin cancer.

Most cancer patients still die in hospital, mainly in medical wards. Many studies in different countries have shown the poor quality of end-of-life care delivery in hospitals. The Program "Liverpool ...Care Pathway for the dying patient" (LCP), developed in the UK to transfer the hospice model of care into hospitals and other care settings, is a complex intervention to improve the quality of end-of-life care. The results from qualitative and quantitative studies suggest that the LCP Program can improve significantly the quality of end-of-life care delivery in hospitals, but no randomised trial has been conducted till now.
This is a randomized cluster trial, stratified by regions and matched for assessment period. Pairs of eligible medical wards from different hospitals will be randomized to receive the LCP-I Program or no intervention until the end of the trial. The LCP-I Program will be implemented by a Palliative Care Unit.The assessment of the end-points will be performed for all cancer deaths occurred in the six months after the end of the LCP-I implementation in the experimental wards and, in the same period of time, in the matched control wards. The primary end-point is the overall quality of end-of-life care provided on the ward to dying cancer patients and their families, assessed using the Global Scale of the Italian version of the Toolkit "After-death Bereaved Family Member Interview".
This study can be interpreted as a Phase III trial according to the Medical Research Council Framework. In this study, the effectiveness of a fully defined intervention is assessed by comparing the distribution of the endpoints in the experimental and in the control arm. RESEARCH ID: RFPS-2006-6-341619

Aims and Background
This study is aimed at evaluating the effectiveness of a physician-centered communication skills training program on cancer patient anxiety levels.
Methods and Study design
In ...this quasi-experimental study, physicians from 9 units of 5 general hospitals and 1 cancer research institute were recruited. The unit heads chose which physicians would attend the training program (treatment group) and which would not (control group). The effectiveness of the course was evaluated by assessing the evolution of state anxiety in a sample of cancer patients before and after clinical consultations.
Results
Thirty-eight physicians and 339 outpatients were assessed. Patients from the treatment and control groups did not differ in pre-examination anxiety or psychological distress levels. Patients examined by physicians from the treatment group displayed a higher decrease in state-anxiety levels compared with those examined by physicians from the control group. A higher proportion of high anxiety levels was found in women, in less educated patients, and in those with a high distress level.
Conclusions
Our findings suggest the effectiveness of the communication skills training program with reference to patient anxiety levels. Given the potential gap between training and clinical impact, further studies investigating the effect of communication training on patient outcomes are needed.

Stage IIIb non-small-cell lung cancer (NSCLC) has a poor prognosis. The median survival is approximately 6 months, and only 30% of patients are alive 1 year after diagnosis. The need for effective ...treatment is evident. The aim of this study was to evaluate whether the infusion of tumor-infiltrating lymphocytes (TILs), isolated from resected tumor, expanded in vitro and injected together with recombinant Interleukin-2, is feasible and may at least partially modify the poor prognosis in these patients. The infusion of TILs, derived from surgically resected NSCLC and expanded in vitro, together with subcutaneous (s.c.) injections of recombinant interleukin-2 (rIL-2) was attempted in a group of 11 patients. Treated patients were infused i.v. with in vitro expanded TILs (from 4 to 70 x 10(9) cells), and rIL-2 was injected s.c. at doses varying from 61 to 378 x 10(6) IU. Toxic side effects (fever and, in some cases, hypotension) were observed and limited the dose of rIL-2 infused. Follow-up was continued for 40 months. The mean survival time was 13.8 months. Three of five TIL-treated patients with residual disease have no evident disease after 1 year, and two of them are still alive and have no evidence of disease after 40 months. This pilot study suggests that the infusion of in vitro expanded TILs, derived from surgical samples, is feasible and seems to prolong overall survival and to control the residual disease in patients with advanced NSCLC.
