Abstract
There is an increasing move to recognize palliative medicine as an area of certificated specialization. Drawing on a survey of palliative care provision in the World Health Organization European region, an overview of palliative care specialization and accreditation practices was presented. Within an international survey to key experts in palliative care carried out in 2005, conducted in 52 countries, a question about the certification for palliative care professionals was included. Information was obtained for 43 of the 52 countries surveyed and all 43 countries (83%) provided data on certification. Palliative medicine has specialty status in just two European countries: Ireland and the UK. In five countries it is considered as a sub-specialty, for which a second certification is required: Poland, Romania, Slovakia and Germany and, recently, France. Some 10 other countries have started the process of certification for palliative medicine, in all cases opting for sub-specialty status that follows full recognition in an established specialty. Across countries there is disparity in the certification criteria followed and considerable variability in the demands that are made in order to achieve certification. Further studies are needed to focus in depth on palliative medicine certification and accreditation across Europe. Establishing uniform approaches to certification for palliative medicine in different European countries will contribute to wider take-up of specialty status and the improved recognition of palliative care as a discipline.

Abstract
The European Association for Palliative Care Task (EAPC) Force on the Development of Palliative Care in Europe was created in 2003 and the results of its work are now being reported in full, both here and in several other publications. The objective of the Task Force is to assess the degree of palliative care development in the European Region as defined by the World Health Organization (WHO). The Task Force is a collaboration between EAPC, the International Observatory on End of Life Care, Help the Hospices and the International Association for Hospice and Palliative Care. The University of Navarra have collaborated in the dissemination of results and is involved in further developments of this group. Four studies, each with different working methods, made up the study protocol: a literature review, a review of all the existing palliative care directories in Europe, a qualitative ;Eurobarometer' survey and a quantitative ;Facts Questionnaire' survey. The work of the Task Force covers the entire WHO European Region of 52 countries. In this article we present a comparative study on the development of palliative care in Europe, drawing on all four elements of the study. Different models of service delivery have been developed and implemented throughout the countries of Europe. For example, in addition to the UK, the countries of Germany, Austria, Poland and Italy have a well-developed and extensive network of hospices. The model for mobile teams or hospital support teams has been adopted in a number of countries, most notably in France. Day Centres are a development that is characteristic of the UK with hundreds of these services currently in operation. The number of beds per million inhabitants ranges between 45-75 beds in the most advanced European countries, to only a few beds in others. Estimates on the number of physicians working full time in palliative care are shown. The countries with the highest development of palliative care in their respective subregions as measured in terms of ratio of services per one million inhabitants are: Western Europe - UK (15); Central and Eastern Europe - Poland (9); Commonwealth of Independent States - Armenia (8). This paper also presents indicators on the development of palliative care based on the bibliometric analysis of scientific journals and on the vitality of the palliative care movement in each country.

Abstract
9027 Background: Historically, there has been no established role for palliative care in treating ambulatory oncology patients who are not at the end of life, but still struggling with the physical, psychosocial and spiritual aspects of cancer. Integrating palliative care services earlier in oncology care may help alleviate the suffering of patients with advanced cancer and family caregivers. This single-arm pilot study examines caregiver satisfaction with early palliative care services in patients with advanced NSCLC. Methods: Sample included patients within 8 weeks of diagnosis of stage IIIb with effusions or IV NSCLC and their family caregivers. Patients met with the palliative care team at least monthly until the time of hospice referral or death, completing assessments of quality of life (FACT-L) and mood (HADS) at baseline, 3, and 6 months. Caregivers rated their satisfaction with palliative care services using the FAMCARE. To identify predictors of caregiver satisfaction with care, patient scores from the FACT-L and HADS were entered into a linear regression model. Results: Fifty-one patients were enrolled (31 female, mean age=64.5 years), with 73% (n=37) identifying a caregiver who consented to participate. Of the 32 caregivers who completed a follow-up assessment, 84% (n=27) reported average FAMCARE scores in the “very satisfied” to “satisfied” range. Patients with worse physical (β=−.49, p=.003) but better social wellbeing (β=.55, p=.001) on the FACT-L at baseline had caregivers who were more satisfied with palliative care services at follow-up. Patient mood symptoms on the HADS were not related to caregiver satisfaction with care. Conclusions: The majority of family caregivers reported being satisfied with oncology care that included early palliative care. Patients with greater physical disability had caregivers who were more satisfied with care, which may be due to increased contact with the palliative care team. Also, patients who felt more supported by their families at baseline had caregivers who were more satisfied with care. While these data are encouraging, controlled longitudinal studies are needed to determine if these findings are actually the result of early palliative care services. [Table: see text]

Abstract
There is a paucity of information on hospice and palliative care provision in Africa and only a weak evidence base upon which to build policy and practice development. We set out to assess the current state of provision across the continent, mapping the existence of services country by country and exploring the perspectives and experiences of those involved. A multi-method review was conducted involving a synthesis of evidence from published and gray literature, ethnographic field visits to seven countries, qualitative interviews with 94 individuals from 14 countries, and the collation of existing public health data. Forty-seven African countries were reviewed, involving the assistance of numerous hospice and palliative care activists, including clinicians, managers, volunteers, policy makers, and staff of donor organizations. The 47 countries of Africa could be grouped into four categories: no identified hospice or palliative care activity (21 countries); capacity building activity is underway to promote hospice and palliative care delivery (11 countries); localized provision of hospice and palliative care is in place, often heavily supported by external donors (11 countries); and hospice and palliative care services are approaching some measure of integration with mainstream service providers and gaining wider policy recognition (four countries). Overall, services remain scattered and piecemeal in most African countries, and coverage is poor. Nongovernmental organizations are the predominant source of provision. Major difficulties relate to opioid availability, workforce development, and achieving sustainable critical mass. Models exist in Uganda, Kenya, South Africa, and Zimbabwe for the development of affordable, sustainable community-based hospice and palliative care services, but sensitivity is required in adopting Western models of hospice and palliative care for implementation in the African cultural context. Overall, interest in the development of hospice and palliative care in Africa has never been greater.

Abstract
There are many palliative care developments in resource-poor regions of the world. Most of them are supported by third-party donors and grant makers. The funding necessary to cover essential palliative care services usually exceeds the financial means of many developing countries. Health care services may have to be complemented by nongovernmental organizations that are dependent on fund raising and voluntary donations from a variety of external sources. Coordinated action by international funding agencies is needed to ensure that the world's poorest people have access to essential medications and appropriate palliative care. To this end, international networking in the palliative care field is vital. There are now a number of collaborative networks that make a significant contribution to the development and sustainability of hospice and palliative care across many resource-poor regions of the world.

Abstract
Loss of insight is one of the core features of frontal/behavioural variant frontotemporal dementia (FTD). FTD shares many clinical and pathological features with corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP). The aim of this study was to investigate awareness of cognitive deficits in FTD, CBD and PSP using a multidimensional approach to assessment, which examines metacognitive knowledge of the disorders, online monitoring of errors (emergent awareness) and ability to accurately predict performance on future tasks (anticipatory awareness). Thirty-five patients (14 FTD, 11 CBD and 10 PSP) and 20 controls were recruited. Results indicated that loss of insight was a feature of each of the three patient groups. FTD patients were most impaired on online monitoring of errors compared to the other two patient groups. Linear regression analysis demonstrated that different patterns of neuropsychological performance and behavioural rating scores predicted insight deficits across the three putative awareness categories. Furthermore, higher levels of depression were associated with poor anticipatory awareness, reduced empathy was related to impaired metacognitive awareness and impaired recognition of emotional expression in faces was associated with both metacognitive and anticipatory awareness deficits. The results are discussed in terms of neurocognitive models of awareness and different patterns of neurobiological decline in the separate patient groups.

Abstract
BACKGROUND Bortezomib is the first proteasome inhibitor to show preliminary evidence of activity against solid tumors. Findings from preclinical studies prompted a Phase I trial to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of bortezomib in combination with gemcitabine in patients with recurring/refractory advanced solid tumors. The effect of gemcitabine on proteasome inhibition by bortezomib in whole blood was also investigated. METHODS Bortezomib was administered as an intravenous bolus injection on Days 1, 4, 8, and 11, with gemcitabine (30-minute infusion) on Days 1 and 8 of a 21-day cycle. Groups of > or =3 patients were evaluated at each dose level. Escalating doses of gemcitabine 500 mg/m(2) to 1000 mg/m(2) with bortezomib 1.0 mg/m(2) to 1.5 mg/m(2) were planned. RESULTS There were no DLTs in patients receiving bortezomib 1.0 mg/m(2) and gemcitabine 500 mg/m(2) to 1000 mg/m(2) in the first 3 dose levels. Dose-limiting nausea, vomiting, gastrointestinal obstruction, and thrombocytopenia occurred in 4 of 5 evaluable patients in dose level 4 (bortezomib 1.3 mg/m(2), gemcitabine 800 mg/m(2)), establishing bortezomib 1.0 mg/m(2) and gemcitabine 1000 mg/m(2) as the MTD. Most common Grade > or =3 toxicities were neutropenia (6 patients), thrombocytopenia (5 patients), gastrointestinal disorders (6 patients), and general disorders (4 patients) such as fatigue. One patient with nonsmall cell lung carcinoma achieved a partial response and 7 achieved stable disease. Inhibition of 20S proteasome activity by bortezomib was unaffected by gemcitabine coadministration. CONCLUSION Dosages of bortezomib and gemcitabine suitable for further evaluation of antitumor activity have been established.

Abstract
PURPOSE To determine the efficacy of cetuximab in patients with recurrent or progressive non-small-cell lung cancer (NSCLC) after receiving at least one prior chemotherapy regimen. PATIENTS AND METHODS This was an open-label, phase II study of patients with epidermal growth factor receptor (EGFR) -positive and EGFR-negative advanced NSCLC with Eastern Cooperative Oncology Group performance status 0 to 1. Patients received cetuximab 400 mg/m2 intravenously (IV) during 120 minutes on week 1 followed by weekly doses of cetuximab 250 mg/m2 IV during 60 minutes. A cycle was considered as 4 weeks of treatment and therapy was continued until disease progression or intolerable toxicities. The primary end point was to assess response rate. Secondary end points included an estimation of time to progression and survival. RESULTS Patient and disease characteristics (n = 66) included EGFR-positive status (n = 60); EGFR-negative status (n = 6); number of prior regimens (one, n = 28; two, n = 27; > or = three, n = 11); male (n = 41); female (n = 25); adenocarcinoma (n = 36); and smoking status (never, n = 13; former, n = 45; current, n = 8). Grade 3/4 toxicities included acne-like rash (6.1%), anaphylactic reactions (1.5%), and diarrhea (1.5%). The response rate for all patients (n = 66) was 4.5% (95% CI, 0.9% to 12.7%) and the stable disease rate was 30.3% (95% CI, 19.6% to 42.9%). The response rate for patients with EGFR-positive tumors (n = 60) was 5% (95% CI, 1.0% to 13.9%). The median time to progression for all patients was 2.3 months (95% CI, 2.1 to 2.6 months) and median survival time was 8.9 months (95% CI, 6.2 to 12.6 months). CONCLUSION Although the response rate with single-agent cetuximab in this heavily pretreated patient population with advanced NSCLC was only 4.5%, the disease control rates and overall survival seem comparable to that of pemetrexed, docetaxel, and erlotinib in similar groups of patients.

Abstract
4064 Background: Weekly irinotecan, cisplatin, and concurrent radiation therapy is a well-tolerated, active regimen in locally advanced esophageal cancer. (Ilson. JCO 2003) Cetuximab, an EGFR inhibitor, is a potent radiation sensitizer in head and neck cancer. (Bonner. Proc ASCO 2004) Methods: In this phase II trial, patients (pts) with T2–4N0–1M0–1A esophageal adenocarcinoma (A) or squamous cell carcinoma (S) receive 5040 cGy/28 fractions of radiation therapy (RT) and concurrent weekly cisplatin 30mg/m2 plus irinotecan 65 mg/m2 on weeks 1, 2, 4, and 5, followed by surgery 4–8 weeks after completion of RT. Additionally, pts receive weekly infusions of cetuximab 250 mg during RT, up to one week before surgery, and for 6 months following surgery. Results: Seventeen pts have been entered: male: female = 14:3, median age 54, ECOG PS 0:1 = 6:11, A:S = 17:0, stage IIA:IIB:III:IVA = 6:1:8:2, tumor location-esophagus-mid:lower:gastroesophageal junction = 1:4:12, >10% weight loss-yes:no = 8:9. Of 17 pts entered, 15 pts have proceeded to surgery, 1 pt died from Aspergillus infection resulting in respiratory failure and sepsis, and 1 pt is pending surgery. Of the 15 pts who underwent surgery, 2 (13%) had a complete pathologic response; pathologic stage for other pts: 0 = 1, I = 3, IIA = 3, IIB = 1, III = 4, IV = 1. Grade III/IV toxicity (17 pts) was: diarrhea 9 pts, neutropenia 9 pts, febrile neutropenia 5 pts, anorexia 5 pts, vomiting 4 pts, fatigue 3 pts, mucositis 1 pt. Chemotherapy dose attenuation was required for diarrhea in 5 pts, for neutropenia in 4 pts, and for folliculitis in 1 pt. One patient was removed from study during week 6 for prolonged diarrhea/ dehydration. Due to the 2-step design of the trial, accrual is on hold pending a 3rd required pathologic CR in the first 17 patients. Conclusions: Compared to other trials of irinotecan, cisplatin, radiation therapy, and surgery in similar groups of esophageal cancer patients, early results for this combination with cetuximab suggest a lower complete response rate and higher overall toxicity. Additional data will be available at ASCO. Supported by Bristol-Myers Squibb. No significant financial relationships to disclose.

Abstract
3018 Background: HKI-272 is a potent, low molecular weight, orally active, irreversible pan erbB receptor tyrosine kinase inhibitor. It inhibits the growth of tumor cells that express erbB-1 (epidermal growth factor receptor, EGFR) and erbB-2 (HER-2) in culture and xenografts. HKI-272 also inhibits the growth of cultured cells that contain sensitizing and resistance-associated EGFR mutations (Kwak et al, Proc Natl Acad Sci USA 102:7665–70, 2005). We are conducting a phase 1 study in patients (pts) with advanced-stage tumors that express EGFR or HER-2 to assess HKI-272 for tolerability, safety, pharmacokinetics, and preliminary antitumor activity. Methods: Pts (3–6/cohort) received 40, 80, 120, 180, 240, 320, or 400 mg HKI-272 orally once on day 1 and then once daily beginning on day 8. Timed blood samples were collected on days 1 and 21 for pharmacokinetic analysis. Results: Enrollment of 73 pts is complete. Preliminary data for 51 pts as of 28 Nov 2005 are presented. Patients were a median 60 years and 26% men. The most frequently occurring tumor types at primary diagnosis were breast (23 pts), non-small cell lung (9), and colorectal, ovarian, and renal (3 pts each). Dose escalation ended when 2 pts who received 400 mg HKI-272/day had drug-related dose-limiting toxicity of grade 3 diarrhea. Thus, the maximum tolerated dose (MTD) was 320 mg HKI-272/day. HKI-272-related adverse events (AEs), any grade, that occurred in ≥10% of pts were diarrhea (84%), nausea (55%), asthenia (45%), anorexia (31%), vomiting (29%), chills (12%), and rash (10%). Grade 3 related AEs that occurred in >1 pt were diarrhea (11) and asthenia (4). HKI-272 Cmax and AUC increased in a dose-dependent manner. At steady state at the MTD, mean values were Cmax: 112±58 ng/mL, AUC: 1618±930 ng.h/mL, t1/2: 15±2.5 h. Day 1 and 21 AUC values were comparable. Tumor assessments (modified RECIST criteria) were made at baseline and at the end of alternate cycles (28 days/cycle). Two breast cancer pts had confirmed partial responses (PRs) and 2 had unconfirmed PRs. Conclusions: When HKI-272 was administered on a continuous, once-daily, oral treatment schedule, the MTD was 320 mg/day, with diarrhea as the most frequently occurring related AE. HKI-272 has antitumor activity in HER-2-positive breast cancer. [Table: see text]

Abstract
Mutations in the PINK1 gene have recently been shown to cause autosomal recessive Parkinson disease (PD). The authors assessed the prevalence of PINK1 gene mutations in 290 well-characterized early- and late-onset PD patients from Ireland. In a 51-year-old PD patient with a family history of PD, the authors identified a novel heterozygous mutation (R147H) in exon 2 of the PINK1 gene. Overall, these data indicate that PINK1 mutations are a rare cause of PD in Ireland.

Abstract
Developments in molecular neuropathology have led to protein-based classification systems for neurodegenerative disorders. Key proteins include alpha-synuclein, amyloid and tau. Alternative mRNA splicing and post-translational change, induced by a bewildering variety of protein modifying processes such as phosphorylation and ubiquitination, have generated insights into new mechanisms of selective neuronal degeneration. The task now is to bring these developments in protein chemistry to the clinic, to try to determine whether this biochemical diversity can help in explaining the phenotypic variability that is so typical of neurodegeneration in general. In this review, we will explore the clinicopathological diversity of the tau-related disorders with specific reference to three of the most common tauopathies, frontotemporal dementia (familial and sporadic), progressive supranuclear palsy and corticobasal degeneration.

Abstract
Chemotherapy extends life and provides symptom palliation for patients with advanced non-small cell lung cancer (NSCLC). Numerous trials have been conducted that evaluate a variety of doublet regimens, but the majority of trials have found equal efficacy among the treatment arms.

Abstract
Chemotherapy extends life and provides symptom palliation for patients with advanced non-small cell lung cancer (NSCLC). Numerous trials have been conducted that evaluate a variety of doublet regimens, but the majority of trials have found equal efficacy among the treatment arms. Indeed, a plateau appears to have been reached with respect to survival associated with traditional cytotoxic drug regimens. It was initially hoped that the addition of novel targeted agents to conventional chemotherapy would produce significant survival benefits for patients with advanced NSCLC; however, most trials have failed to show such a benefit. There is no survival benefit associated with adding erlotinib or gefitinib to a chemotherapy regimen, although there is a significant improvement in survival associated with erlotinib monotherapy in the second- and third-line advanced disease setting. In contrast, the results of E4599 clearly demonstrate that the addition of bevacizumab to paclitaxel-carboplatin chemotherapy extends survival in a select group of patients with non-squamous cell NSCLC. E4599 also represents a rational approach to drug development that could be modeled in other trials, namely, the use of a large, well designed, randomized trial prior to beginning a traditional phase II approach. This strategy can lead to the identification of subgroups most likely to benefit, as well as those that might experience increased toxicity, such as patients with squamous cell carcinoma treated with bevacizumab. Another approach to optimizing targeted therapy involves selecting a chemotherapy regimen with the greatest potential for synergy based on preclinical modeling.

Abstract
Somatosensory abnormalities are found in adult-onset primary torsion dystonia (PTD). Therefore we assessed spatial discrimination thresholds (SDT), a measure of spatial acuity, in four multiplex families with adult-onset PTD. In family members aged 20 to 45 years vs controls (mean + 2.5 SD), abnormal SDTs were found in four of five affected with adult-onset PTD and in 12 of 49 unaffected relatives. Sensory abnormalities may be an endophenotype, possibly expressed later as adult-onset PTD.
