RESUMEN
BACKGROUND: Cancer-related fatigue (CRF) is common in patients with advanced solid tumors and several risk factors are described. The possible role of depression is reported by clinicians despite the association with CRF being unclear. MATERIAL AND METHODS: In this monocentric, cross-sectional, prospective study we recruited patients with advanced solid tumors who were hospitalized at Fondazione IRCCS Istituto Nazionale dei Tumori of Milan. The primary objective was to assess the correlation between CRF and depression. Secondary objectives were the estimation of CRF and depression prevalence and the identification of associated clinical risk factors. CRF and depression were evaluated through the Functional Assessment of Cancer Therapy-Fatigue subscale and the Zung Self Depression Scale (ZSDS) questionnaires. The Cochran-Armitage trend test was used to demonstrate the primary hypothesis. Univariate and multivariate logistic regression models were used to investigate the impact of clinical variables. RESULTS: A total of 136 patients were enrolled. The primary analysis found a linear correlation (P < 0.0001) between CRF and depression. The prevalence of CRF and of moderate to severe depressive symptoms was 43.5% and 29.2%, respectively. In univariate analysis, patients with poor Eastern Cooperative Oncology Group performance status (ECOG PS), anemia, distress, pain, and receiving oncological treatment were at a significantly higher risk for CRF, whereas poor ECOG PS, pain, and distress were risk factors for depression. In multivariate analysis, high levels of ZSDS were confirmed to be correlated to CRF: odds ratio of 3.86 [95% confidence interval (CI) 0.98-15.20) and 11.20 (95% CI 2.35-53.36) for ZSDS of 50-59 and 60-100, respectively (P value for trend 0.002). Moreover, the ECOG PS score was confirmed to be significantly associated with CRF (OR 7.20; 95% CI 1.73-29.96; P = 0.007). CONCLUSIONS: Our data suggest a strong correlation between CRF and depression in patients with advanced solid tumors. Further investigations are needed to better understand this relationship and if depressive disorder therapeutic strategies could also impact on CRF.

Dupuytren Disease is a benign fibromatosis of palmar fascia of the hand, whose pathophysiology is not completely understood. The present study is intended to provide a description of the effects of Collagenase of Clostridium Hystoliticum (CCH) into an injected cord of Dupuytren. Our experimental study wanted to evaluate the histological effects of injection of CCH in the first 24 hours, without manipulating the specimens. MATERIALS AND METHODS: Surgical specimens were injected with CCH, and then fixed in formalin every six hours, up to 24 hours. Those specimens were compared to control specimen (non-injected), fixed and analyzed at the same times. RESULTS: In the injected specimens, the number of CD68 positive cells increased into and outside the cords compared to non injected specimens, within the same time from the surgical removal. CONCLUSION: CCH has a proinflammatory activity and provokes a short ray chemotactic action on white blood cells. The lysis of the cord induced by CCH stimulates the inflammatory response. The role of the inflammatory infiltration deserves to be investigated in a more accurate way, preferably by using in vivo studies.

Anorexia nervosa (AN) is an eating disorder that most frequently afflicts females in adolescence. In these subjects, cardiovascular complications are the main cause of morbidity and mortality. Aim of this review is to analyze the hemodynamic, pro-arrhythmic and structural changes occurring during all phases of this illness, including re-feeding. A systematic literature search was performed on studies in the MEDLINE database, from its inception until September 2017, with PUBMED interface focusing on AN and cardiovascular disease. This review demonstrated that the most common cardiac abnormalities in AN are bradycardia and QT interval prolongation, which may occasionally degenerate into ventricular arrhythmias such as Torsades des Pointes or ventricular fibrillation. As these arrhythmias may be the substrate of sudden cardiac death (SCD), they require cardiac monitoring in hospital. In addition, reduced cardiac mass, with smaller volumes and decreased cardiac output, may be found. Furthermore, mitral prolapse and a mild pericardial effusion may occur, the latter due to protein deficiency and low levels of thyroid hormone. In anorectic patients, some cases of hypercholesterolemia may be present; however, conclusive evidence that AN is an atherogenic condition is still lacking, although a few cases of myocardial infarction have been reported. Finally, refeeding syndrome (RFS), which occurs during the first days of refeeding, may engender a critically increased risk of acute, life-threatening cardiac complications.

PURPOSE: Explore clinical factors associated with higher pain intensity and future pain in patients with bone metastases to identify patients who can benefit from closer follow-up or pain-modifying interventions. METHODS: This is a secondary analysis of 606 patients with bone metastases included in a multicenter longitudinal study. The dependent variables were "average pain" and "worst pain" in the last 24 h (0-10 NRS). Twenty independent variables with potential association to pain intensity were selected based on previous literature. Cross-sectional analyses were performed with multiple linear regression to explore factors associated with pain intensity at baseline. Longitudinal data were analyzed with a generalized equation models to explore current factors associated with pain intensity at the next visit in 1 month. RESULTS: Current pain intensity (p < 0.001), sleep disturbances (p 0.01 and 0.006), drowsiness (p 0.003 and 0.033) and male gender (p 0.045 and 0.001) were associated with higher average and worst pain intensity in 1 month. In addition, breakthrough pain was related to higher worst pain intensity (p 0.003) in 1 month. The same variables were also associated with higher average pain intensity at baseline. CONCLUSION: Higher current pain intensity, sleep disturbances, drowsiness, male gender, and breakthrough pain are factors associated with higher pain intensity in patients with bone metastases at the next follow-up in 1 month. These factors should be assessed in clinical practice and may aid clinicians in identifying patients that can benefit from closer follow-up or interventions to prevent lack of future pain control.

OBJECTIVES: Palliative care (PC) services and patients differ across countries. Data on PC delivery paired with medical and self-reported data are seldom reported. Aims were to describe (1) PC organisation and services in participating centres and (2) characteristics of patients in PC programmes. METHODS: This was an international prospective multicentre study with a single web-based survey on PC organisation, services and academics and patients' self-reported symptoms collected at baseline and monthly thereafter, with concurrent registrations of medical data by healthcare providers. Participants were patients ≥18 enrolled in a PC programme. RESULTS: 30 centres in 12 countries participated; 24 hospitals, 4 hospices, 1 nursing home, 1 home-care service. 22 centres (73%) had PC in-house teams and inpatient and outpatient services. 20 centres (67%) had integral chemotherapy/radiotherapy services, and most (28/30) had access to general medical or oncology inpatient units. Physicians or nurses were present 24â hours/7â days in 50% and 60% of centres, respectively. 50 centres (50%) had professorships, and 12 centres (40%) had full-time/part-time research staff. Data were available on 1698 patients: 50% females; median age 66 (range 21-97); median Karnofsky score 70 (10-100); 1409 patients (83%) had metastatic/disseminated disease; tiredness and pain in the past 24â hours were most prominent. During follow-up, 1060 patients (62%) died; 450 (44%) <3â months from inclusion and 701 (68%) within 6â months. ANOVA and χ2 tests showed that hospice/nursing home patients were significantly older, had poorer performance status and had shorter survival compared with hospital-patients (p<.0.001). CONCLUSIONS: There is a wide variation in PC services and patients across Europe. Detailed characterisation is the first step in improving PC services and research.

OBJECTIVE: FNA biopsy is considered as the most accurate method for the selection of patients with thyroid nodules that need for surgery or for the wait and see management. The aim of the present study is to clarify the risk of malignancy for the cytological data classified according to the 2014 Italian reporting system. METHODS: We report a retrospective analysis of 4043 patients in our institution's experience during the period April 2014 through December 2016 with the Italian reporting system for thyroid cytology. RESULTS: The diagnostic incidences of the 4043 cases were as follows: 9.8% TIR1; 1.3% TIR1C; 70% TIR2; 6.6% TIR3A; 4.5% TIR3B; 2.4% TIR4; 5.2% TIR5. A repeated aspiration was carried out in 68 out of 269 cases (25%) classified as TIR3A. A total of 407 cases with cytology underwent surgical resection. A malignant neoplasm was detected in 261 out of 407 (64%) cases. Regarding TIR3B, surgical excision was undertaken in 109 cases, which included 42 high-risk lesions and 67 Hürthle cell neoplasms. The risk of malignancy was significantly higher in the former compared to the latter (50% vs 9%; P<.05). CONCLUSIONS: This investigation emphasises the reliability of the 2014 Italian Reporting System concerning the mutual frequency of the diagnostic categories. The risk of malignancy is perfectly within the range of the estimated values.

Myostatin (Mstn) is a skeletal muscle growth inhibitor involved in metabolic disorders and heart fibrosis. In this study we sought to verify whether Mstn is also operative in atherosclerosis of abdominal aorta. In human specimens, Mstn expression was almost absent in normal vessels, became detectable in the media of non-progressive lesions and increased with the severity of the damage. In progressive atherosclerotic lesions, Mstn was present in the media, neointima, plaque shoulder and in infiltrating macrophages. Mstn co-localized with α-smooth muscle actin (α-SMA) staining and with some CD45+ cells, indicating Mstn expression in VSMCs and bloodstream-derived leukocytes. In vitro, Mstn was tested in VSMCs and monocytes. In A7r5 VSMCs, Mstn downregulated proliferation and Smoothelin mRNA, induced cytoskeletal rearrangement, increased migratory rate and MCP-1/CCR2 expression. In monocytes (THP-1 cells and human monocytes), Mstn acted as a chemoattractant and increased the MCP-1-dependent chemotaxis, F-actin, α-SMA, MCP-1 and CCR2 expression; in turn, MCP-1 increased Mstn mRNA. Mstn induced JNK phosphorylation both in VSMCs and monocytes. Our results indicate that Mstn is overexpressed in abdominal aortic wall deterioration, affects VSMCs and monocyte biology and sustains a chronic inflammatory milieu. These findings propose to consider Mstn as a new playmaker in atherosclerosis progression.

OBJECTIVE: To explore the role of diffusion-weighted imaging (DWI) in the staging of axillary lymph nodes and the restaging after neoadjuvant chemotherapy (NAD) in advanced breast cancer. PATIENTS AND METHODS: MRI examinations of forty-two patients diagnosed with advanced breast cancer addressed to NAD and axillary lymph node dissection (ALND) were reviewed. Apparent diffusion coefficients (ADC) of each visible node in DWI in the pathologic axilla (PA) and healthy axilla (HA) were measured at the time of diagnosis (t0) and after chemotherapy (t1); mean values of the ADC were calculated. Patients were classified as responders (R), non-responders (NR), macrometastasis (MA), micrometastasis (Mi). RESULTS: Mean ADC was 0.92 ± 0.07 x 10-3 mm2/sec at t0 and 0.97 ± 0.06 x 10-3 mm2/sec at t1 (p = 0.284) in PA, 0.89 ± 0.06 x 10-3 mm2/sec at t0 and 0.92 ± 0.06 x 10-3 mm2/sec at t1 (p = 0.403) in HA, 0.95 ± 0.111 x 10-3 mm2/sec at t0 and 0.95 ± 0.14 x 10-3 mm2/sec at t1 (p = 0.954) in R group, 0.90 ± 0.09 x 10-3 mm2/sec at t0 and 0.97 ± 0.07 x 10-3 mm2/sec at t1 (p = 0.085) in NR group, 0.86 ± 0.10 x 10-3 mm2/sec at t0 and 0.99 ± 0.09 x 10-3 mm2/sec at t1 (p = 0.055) in MA, and 0.99 ± 0.23 x 10-3 mm2/sec at t0 and 0.95 ± 0.15 x 10-3 mm2/sec at t1 in Mi (p = 0.667). CONCLUSIONS: Mean ADC between PA and HA, R and NR, MA and Mi did not significantly differ at t0 and t1 (p > 0.05). Variation in mean ADC between t0 and t1 was not significant in all groups (p > 0.05), except for a trend toward significance (p = 0.055) in MA. DWI has a potential role in restaging of macrometastatic axillary nodes after NAD.

BACKGROUND: More than 60 per cent of patients treated surgically for primary retroperitoneal sarcoma survive for at least 5 years. Extended surgical resection has been proposed for primary disease, but long-term morbidity data are lacking. A cross-sectional study was conducted to assess the long-term morbidity of patients undergoing surgery for retroperitoneal sarcoma. METHODS: Patients operated on between January 2002 and December 2011 were eligible for the study. Long-term morbidity was evaluated based on a semistructured clinical interview. Lower limb function was assessed by means of the Lower Extremity Functional Scale (LEFS), a self-report questionnaire with a total score ranging from 0 (low functioning) to 80 (high functioning). Pain was investigated by means of the Brief Pain Inventory--Short Form, with pain intensity scores reported on a scale from 0 (no pain) to 10 (worst pain). RESULTS: Some 243 patients underwent surgery, and 101 of 160 patients who were alive at the time of the investigation responded to the study invitation letter. Finally, 95 patients were enrolled in the study. Sensory impairment of the limbs was reported in 72 patients (76 per cent). The median LEFS score was 60 (i.q.r. 43-73). Mean scores for the pain intensity items varied from 1.23 to 2.68. In multivariable analysis, there was no difference in median levels of creatinine at survey between patients who did or did not undergo nephrectomy (difference between median values 13 (95 per cent c.i. -4 to 30) µmol/l; P = 0.170). CONCLUSION: Severe chronic pain and lower limb motor impairment after multivisceral resection for retroperitoneal sarcomas are rare. Long-term renal function is not significantly impaired when nephrectomy is performed.

We present a case of a 58 year-old woman with primary chylopericardium associated with chylothorax. Chylopericardium is a condition in which chylous fluid containing a high concentration of triglycerides accumulates in the pericardial cavity, and it can form for many different reasons. 3D computed tomography with lymphography precisely depicted the specific location of the lymphatic leak in this patient, which was successfully repaired using targeted video assisted thoracic surgery (VATS).

This study was performed to describe the impact of preventive options on the psychological condition of BRCA1/BRCA2 carriers. A sample of 52 cancer-affected (C-A) and 27 cancer-unaffected (C-UN) women were enrolled after gene test disclosure (T0). Psychological evaluations were performed at T0 and 15 months later (T1). The surgical options were more likely to be chosen in C-A women (62%), although a consistent proportion of C-UN women (30%) also opt for these preventive measures. At the baseline, both samples had average anxiety and depression scores below the cut-off value, restrained average cancer worry scores and a risk perception consistent with the risk percentage provided during genetic counselling. The longitudinal results indicated no clinically meaningful variations in the anxiety and depression scores in either of the two samples. Statistically significant reductions in cancer-risk perception emerged in women who chose surgery in both C-A and C-UN women. In BRCA1/BRCA2 mutation carriers, surveillance does not influence their initial psychological condition, whereas prophylactic surgery has a significant impact in reducing the perceived risk and worry about getting sick. C-A and C-UN women have to be considered as two separate populations of BRCA mutation carriers requiring personalized approaches to risk management.

We examined the contribution of arterial wave reflection to early abnormalities in left ventricular relaxation, whether this association was modified by gender or hypertension and the role of reflected wave timing and amplitude. We studied a cohort of normotensive and untreated essential hypertensive Taiwanese participants (675 men, 601 women, mean age 52 years). Doppler flow and applanation tonometry were performed to assess carotid-femoral pulse wave velocity (PWV) and augmentation index (AI). Diastolic parameters including the ratio between the peak velocity of early and late diastolic mitral inflow (E/A), E-deceleration time and left atrial (LA) diameter were measured by echocardiography. In multivariate models predicting E/A, women were more likely to have lower E/A than men (ß=-0.08, P<0.001). AI was significantly associated with lower E/A in both men (ß=-0.09, P=0.005) and women (ß=-0.12, P<0.001) independent of PWV. Inclusion of AI in the overall model reduced the gender difference in E/A by 61% and rendered it nonsignificant. There was a significant interaction between AI and hypertension (P=0.02). The inverse association between AI and E/A was significant only in normotensive men and women, and only for the amplitude but not timing of the reflected wave. In conclusion, the contribution of wave reflection to left ventricular diastolic dysfunction was independent of arterial stiffness, more pronounced in normotensive individuals and explained a significant portion of the gender difference in diastolic function.

Electrical storm (ES) describes the rapidly clustering ventricular fibrillation (VF) that requires multiple cardioversions. Emerging evidence suggests that Purkinje arborization and sympathetic nerve regeneration play a major role in initiating malignant arrhythmias. We report the case of two patients who, after having survived an acute myocardial infarction (MI), developed repetitive episodes of polymorphic ventricular tachycardia and VF one week after percutaneous revascularization, triggered by monomorphic premature ventricular contractions (PVCs). Owing to repetitive and drug-refractory VF episodes, temporary atrial overdrive pacing was attempted with complete suppression of VF. In the following month, recurrence of ventricular arrhythmia was inversely related to the atrial pacing rate. Although antiarrhythmic drugs other than beta-blockers had been discontinued, neither PVCs nor ventricular arrhythmias recurred at one-month follow-up when the lower pacing rate was set at 60 bpm. In conclusion in these patients, ES was likely related to nerve sprouting after ischemic injury. This chaotic phenomenon occurs early after tissue damage and shows a peak seven days after acute MI with degeneration of superfluous axon branches. High pacing rates can reduce early after depolarizations and suppress PVCs, thus preventing ES. On these grounds, ES patients may be treated with temporary overdrive pacing rather than early radiofrequency ablation.

BACKGROUND AND AIMS: It is unclear whether subcutaneous and visceral fat are differentially correlated to the decline in left ventricular (LV) diastolic function with aging. This study sought to examine the hypothesis that age-related changes in the regional fat distribution account for changes in LV diastolic function and to explore potential mediators of this association. METHODS AND RESULTS: In this cross-sectional study, we evaluated 843 participants of the Baltimore Longitudinal Study of Aging with echocardiogram, dual-energy X-ray absorptiometry (DEXA), abdominal computed tomography (CT) and blood tests performed at the same visit. LV diastolic function was assessed by parameters of LV relaxation (E/A ratio, Em and Em/Am ratio) and LV filling pressures (E/Em ratio). Total body fat was computed by DEXA, while visceral and subcutaneous fat were determined from abdominal CT. In multivariate models adjusted for demographics, cardiovascular risk factors, antihypertensive medications, physical activity and LV mass, both visceral and subcutaneous fat were associated with LV diastolic dysfunction. When both measures of adiposity were simultaneously included in the same model, only visceral fat was significantly associated with LV diastolic dysfunction. Triglycerides and sex-hormone binding globulin, but not adiponectin and leptin, were found to be significant mediators of the relationship between visceral fat and LV diastolic function, explaining 28-47% of the association. Bootstrapping analyses confirmed the significance of these findings. CONCLUSIONS: Increased visceral adiposity is associated with LV diastolic dysfunction, possibly through a metabolic pathway involving blood lipids and ectopic fat accumulation rather than adipokines.

BACKGROUND: Opioid consumption data in Italy have been widely studied. However, only aggregate data can be found in the published literature, and differences are expected by distribution setting (community pharmacies and hospitals). The aim of our paper is to analyse opioids sales trends in Italy in the decade 2000-2010, in an effort to explore such differences. METHODS: Quarterly sales data of opioid medicinal products sold by wholesalers to both community pharmacies (retail) and to hospitals (non-retail) during the time period 2000-2010 were supplied by IMS Italy. Data were standardized using the Defined Daily Doses per day per 1000 inhabitants (DDDd/1000). RESULTS: Opioid sales have steadily increased during the time period considered going from 1.04 DDDd/1000 in 2000 to 4.9 in 2010 (+292%). Nonetheless relevant differences can be found both by distribution setting and drug type. In particular retail sales have increased by 286 % for WHO Step II opioids and by 575% for WHO Step III drugs, while non-retail sales have increased by 48% and 263%, respectively. In 2010, fentanyl and buprenorphine transdermal patches and oxycodone are more widely prescribed than morphine, in the retail setting, with fentanyl at large in the first position. In hospitals morphine and fentanyl almost equally share the 75% of the market. CONCLUSION: Data suggest that morphine is no more the opioid of first choice for severe pain in Italy, at least for outpatients. This is contradicting most international guidelines available in the 2000-2010 decade.

Inflammatory and immunologic mechanisms are important for the initiation and the progression of atherosclerotic lesions. OxLDL and HSP-60 antigens are involved in the pathogenesis of atherosclerotic disease by triggering immune cells within the plaques. Through the MHC pentamer assays, we investigated the presence of OxLDL- and HSP-60-specific CD8(+) T lymphocytes in twenty HLA-A2-positive patients suffering from coronary artery disease (10 NSTEMI and 10 stable angina). Similarly, 10 age- and sex-matched healthy subjects were enrolled as controls. Biological samples were collected within 6 h of admission to hospital, at 30 days and at 180 days. OxLDL- and HSP-60-specific CD8(+) T lymphocytes were never detectable in the peripheral blood from all the healthy controls. On the contrary, at each scheduled time point, both of these specific cells could be detected in peripheral blood from all enrolled patients. More in detail, the flow cytometric analysis of MHC-1 pentamer OxLDL-specific CD8(+) T lymphocytes revealed a sharp and significant increase at the hospital admission, within 6 h from the chest pain onset, followed by an evident decline to lower levels at 30 days and at 180 days from the enrollment in the study. On the contrary, although MHC-1 pentamer HSP-60 CD8(+) T lymphocytes were detectable in enrolled patients, almost no variance could be detectable during the follow-up scheduled evaluations. On the whole, this finding indicates that HSP-60- and OxLDL-specific CD8(+) T lymphocytes could play a role in the maintenance or worsening of the atherosclerotic coronary disease.

OBJECTIVES: The effects of vitamin D on the heart have been studied in patients with cardiac disease, but not in healthy persons. We investigated the relation between vitamin D status and left ventricular (LV) structure and function in community-dwelling subjects without heart disease. DESIGN: The relationship between concentrations of 25-hydroxyvitamin D [25(OH)D], a marker of vitamin D reserve, and LV transthoracic echocardiography measures was analysed in 711 participants in the Baltimore Longitudinal Study of Aging who were without cardiac disease. RESULTS: Mean 25(OH)D in the study population was 32.3 ± 11.4 ng mL(-1) ; only 15.5% of subjects had moderate or severe vitamin D deficiency [25(OH)D < 20 ng mL(-1) ]. Adjusting for age, body mass index, cardiovascular disease risk factors, physical activity, calcium and parathyroid hormone, 25(OH)D was positively correlated with LV thickness (ß 0.095, SE 0.039, P < 0.05) and LV mass index (ß 7.5, SE 2.6, P < 0.01). A significant nonlinear relation between 25(OH)D and LV concentric remodelling was observed. LV remodelling was more likely in participants with 25(OH)D levels <30 ng mL(-1) [odds ratio (OR) 1.24; 95% confidence interval (CI) 0.83-1.85] or ≥38 ng mL(-1) (OR 1.73; 95% CI 1.13-2.65), compared with those with 30-37 ng mL(-1) 25(OH)D. Consistently, LV relative wall thickness was significantly lower (P for trend=0.05), and LV diastolic internal diameter index (P for trend<0.05) and end-diastolic volume index (P for trend<0.05) were significantly higher in subjects with 30-37 ng mL(-1) 25(OH)D compared to the rest of the study population. There was a significant interaction between 25(OH)D and hypertension on the risk of LV hypertrophy (P < 0.05). CONCLUSIONS: In a population-based sample of predominantly vitamin D-sufficient subjects without heart disease, LV geometry was most favourable at intermediate 25(OH)D concentrations.

BACKGROUND: Dealing with cancer pain implies assessing the intensity and other attributes of pain and identifying appropriate outcomes and endpoints to evaluate the effect of treatments. METHODS: In the context of an observational longitudinal prospective study, 1461 painful cancer patients were evaluated at baseline and weekly over 4 weeks. Four pain intensity (PI) measures (worst, average, least and right now: WP, AP, LP, and PRN), pain relief and patients' satisfaction with pain treatments were recorded. Starting from these data, we extrapolated the full responder (FR) subjects, whose PI decreased by ≥2 points, or by ≥30%, or who obtained a final score of ≤5 points, according to criteria previously suggested by literature. The receiver operating characteristics (ROC) curve analysis was used to estimate the predictive accuracy. RESULTS: All the PI measures decreased from the initial to final visit: the reduction was 1.9 as WP, 1.3, 0.8 and 1.2 as AP, LP and PRN, respectively. The proportion of FR differed from 47.8% to 88.3% depending on PI measures and the criterion adopted. ROC analysis showed an acceptable accuracy of all endpoints and confirmed the cut-offs recommended by the literature. The best criterion corresponded to a PI absolute value of ≤4 points when measured as AP. CONCLUSIONS: All measures applied seem able to profile the evolution of pain, with some differences. This implies the need of an appropriate choice of outcomes and endpoints according to the goal and objective of the intervention under evaluation.

The aim of the present study is to describe end-of-life preferences of advanced cancer patients willing to talk about death issues. Eighty-eight advanced cancer patients were interviewed through End of Life Preferences Interview (ELPI), a 23-item interview covering a wide range of end-of-life care issues. Most interviewed subjects were home care patients and their median survival after ELPI administration was 69 days. In total, 100% of responders expressed the will to receive some kind of information on the disease process and/or the treatments proposed. Approximately 77% declared to be willing to talk about what it is important at the end of life in case of worsening of their conditions and 31% prefer to be left alone in difficult moments. Approximately 67% choose home as the preferred place of death and 63% think it is preferable to die in a state of unconsciousness induced by drugs. About half of responders declare to believe in any kind of life after death and 40% consider very important to find any meaning at the end of life. ELPI can be a useful instrument to adapt the model of care to the specific needs and values of each patient.
