A new chemical tool (C0036E08) supports the role of adenosine A(2B) receptors in mediating human mast cell activation.

Asthma is a chronic inflammatory disease of the airways that involves many cell types, amongst which mast cells are known to be important. Adenosine, a potent bronchoconstricting agent, exerts its ability to modulate adenosine receptors of mast cells thereby potentiating derived mediator release, histamine being one of the first mediators to be released. The heterogeneity of sources of mast cells and the lack of highly potent ligands selective for the different adenosine receptor subtypes have been important hurdles in this area of research. In the present study we describe compound C0036E08, a novel ligand that has high affinity (pK(i) 8.46) for adenosine A(2B) receptors, being 9 times, 1412 times and 3090 times more selective for A(2B) receptors than for A(1), A(2A) and A(3) receptors, respectively. Compound C0036E08 showed antagonist activity at recombinant and native adenosine receptors, and it was able to fully block NECA-induced histamine release in freshly isolated mast cells from human bronchoalveolar fluid. C0036E08 has been shown to be a valuable tool for the identification of adenosine A(2B) receptors as the adenosine receptors responsible for the NECA-induced response in human mast cells. Considering the increasing interest of A(2B) receptors as a therapeutic target in asthma, this chemical tool might provide a base for the development of new anti-asthmatic drugs.

Simultaneous CD8+ T cell responses to multiple tumor antigen epitopes in a multipeptide melanoma vaccine.

The recent identification and molecular characterization of tumor-associated antigens recognized by tumor-reactive CD8+ T lymphocytes has led to the development of antigen-specific immunotherapy of cancer. Among other approaches, clinical studies have been initiated to assess the in vivo immunogenicity of tumor antigen-derived peptides in cancer patients. In this study, we have analyzed the CD8+ T cell response of an ocular melanoma patient to a vaccine composed of four different tumor antigen-derived peptides administered simultaneously in incomplete Freund's adjuvant (IFA). Peptide NY-ESO-1(157-165) was remarkably immunogenic and induced a CD8+ T cell response detectable ex vivo at an early time point of the vaccination protocol. A CD8+ T cell response to the peptide analog Melan-A(26-35 A27L) was also detectable ex vivo at a later time point, whereas CD8+ T cells specific for peptide tyrosinase(368-376) were detected only after in vitro peptide stimulation. No detectable CD8+ T cell response to peptide gp100(457-466) was observed. Vaccine-induced CD8+ T cell responses declined rapidly after the initial response but increased again after further peptide injections. In addition, tumor antigen-specific CD8+ T cells were isolated from a vaccine injection site biopsy sample. Importantly, vaccine-induced CD8+ T cells specifically lysed tumor cells expressing the corresponding antigen. Together, these data demonstrate that simultaneous immunization with multiple tumor antigen-derived peptides can result in the elicitation of multiepitope-directed CD8+ T cell responses that are reactive against antigen-expressing tumors and able to infiltrate antigen-containing peripheral sites.

Toux sèche, douleurs thoraciques et dyspnée chez un patient atteint d'une polyarthrite rhumatoïde [Dry cough, chest pain and difficult breathing in a patient with rheumatoid arthritis]

Pulmonary involvement is the most frequent extra-articular manifestation of rheumatoid arthritis. The occurrence of a chronic hydro-pneumo-thorax associated with pulmonary nodules is rare. Cavitation of the most superficial nodules and their rupture into the pleural cavity are most likely involved in this complication. The presence of broncho-pleural fistulae may be responsible for the persistence of the phenomenon in our patient.

Recognition of RNA virus by RIG-I results in activation of CARD9 and inflammasome signaling for interleukin 1 beta production.

Interleukin 1 beta (IL-1 beta) is a potent proinflammatory factor during viral infection. Its production is tightly controlled by transcription of Il1b dependent on the transcription factor NF-kappaB and subsequent processing of pro-IL-1 beta by an inflammasome. However, the sensors and mechanisms that facilitate RNA virus-induced production of IL-1 beta are not well defined. Here we report a dual role for the RNA helicase RIG-I in RNA virus-induced proinflammatory responses. Whereas RIG-I-mediated activation of NF-kappaB required the signaling adaptor MAVS and a complex of the adaptors CARD9 and Bcl-10, RIG-I also bound to the adaptor ASC to trigger caspase-1-dependent inflammasome activation by a mechanism independent of MAVS, CARD9 and the Nod-like receptor protein NLRP3. Our results identify the CARD9-Bcl-10 module as an essential component of the RIG-I-dependent proinflammatory response and establish RIG-I as a sensor able to activate the inflammasome in response to certain RNA viruses.

Prognostic importance of hyponatremia in patients with acute pulmonary embolism

Rapport de synthèse Enjeux et contexte: L'hyponatrémie est un trouble électrolytique fréquent et associé à un pronostic défavorable dans de nombreuses affections card iovascu lai res (1-5), pour lesquelles il est un marqueur de l'activation neurohumorale (6). Sa valeur pronostique chez les patients se présentant avec une emboîie pulmonaire était jusque là inconnue ; elle fait l'objet de la présente étude.Objectifs: Examiner chez les patients hospitalisés pour une embolie pulmonaire, les associations entre hyponatrémie et mortalité ainsi qu'avec le taux de réhospitalisation. Méthodes: Nous avons étudié les données de 13728 patients avec un diagnostic principal d'embolie pulmonaire provenant de 185 hôpitaux en Pennsylvanie (janvier 2000 à novembre 2002.) Nous avons utilisé un modèle de régression logistique afin d'établir l'association indépendante entre le niveau de sodium lors de la présentation aux urgences et la mortalité ainsi que le taux de ^hospitalisation durant 30 jours. Nous avons ajusté pour les caractéristiques du patient (race, assurance, sévérité de la maladie, usage de la thrombolyse) et de l'hôpital (région, taille, avec ou sans médecins en formation.)Résultats principaux: Une hyponatrémie (sodium £ 135 mmol/l) était présente chez 2907 patients (21.1%). Les patients avec un sodium >135, 130-135, et <130 mmol/l avaient une mortalité cumulée à 30 jours de 8.0%, 13.6%, et 28.5% (P <0.001), et un taux de réadmission de 11.8%, 15.6%, et 19.3% (P <0.001), respectivement. Comparés aux patients avec un sodium >135 mmol/l, les odd ratios ajustés concernant la mortalité étaient significativement plus important pour les patients avec un sodium compris entre 130 et 135 mmol/l (OR 1.53, 95% Cl: 1.33-1.76) ou <130 mmol/l (OR 3.26, 95% Cl: 2.48-4.29). Les odd ratios ajustés concernant la réhospitalisation étaient également augmentés pour les patients présentant un sodium entre 130 et 135 mmol/l (OR 1.28, 95% Cl: 1.12-1.46) ou <130 mmol/l (OR 1.44, 95% Cl: 1.02-2.02). Conclusions et perspectives: L'hyponatrémie est fréquente chez les patients se présentant avec une embolie pulmonaire, de plus elle est un prédicateur indépendant de la mortalité à court terme, ainsi que du taux de réhospitalisation. La natrémie est une information généralement disponible lors de l'établissement d'un pronostic. Bien que cette association soit compatible avec une activation neurohumorale, nous ne pouvons pas attester des mécanismes impliqués, du fait que notre étude ne donne pas d'informations sur d'autres étapes de la physiologie de cette association.

Patient and physician gender concordance in preventive care in university primary care settings.

OBJECTIVE: To assess the quality of preventive care according to physician and patient gender in a country with universal health care coverage. METHODS: We assessed a retrospective cohort study of 1001 randomly selected patients aged 50-80years followed over 2years (2005-2006) in 4 Swiss university primary care settings (Basel, Geneva, Lausanne, Zürich). We used indicators derived from RAND's Quality Assessment Tools and examined percentages of recommended preventive care. Results were adjusted using hierarchical multivariate logistic regression models. RESULTS: 1001 patients (44% women) were followed by 189 physicians (52% women). Female patients received less preventive care than male patients (65.2% vs. 72.1%, p<0.001). Female physicians provided significantly more preventive care than male physicians (p=0.01) to both female (66.7% vs. 63.6%) and male patients (73.4% vs. 70.7%). After multivariate adjustment, differences according to physician (p=0.02) and patient gender (p<0.001) remained statistically significant. Female physicians provided more recommended cancer screening than male physicians (78.4 vs. 71.9%, p=0.01). CONCLUSIONS: In Swiss university primary care settings, female patients receive less preventive care than male patients, with female physicians providing more preventive care than male physicians. Greater attention should be paid to female patients in preventive care and to why female physicians tend to provide better preventive care.

Increased activation in Broca's area after cognitive remediation in schizophrenia.

Functional magnetic resonance imaging (fMRI) was used to measure changes in cerebral activity in patients with schizophrenia after participation in the Cognitive Remediation Program for Schizophrenia and other related disorders (RECOS). As RECOS therapists make use of problem-solving and verbal mediation techniques, known to be beneficial in the rehabilitation of dysexecutive syndromes, we expected an increased activation of frontal areas after remediation. Executive functioning and cerebral activation during a covert verbal fluency task were measured in eight patients with schizophrenia before (T1) and after (T2) 14 weeks of RECOS therapy. The same measures were recorded in eight patients with schizophrenia who did not participate in RECOS at the same intervals of time (TAU group). Increased activation in Broca's area, as well as improvements in performance of executive/frontal tasks, was observed after cognitive training. Metacognitive techniques of verbalization are hypothesized to be the main factor underlying the brain changes observed in the present study.

Theoretical study on receptor-G protein recognition: new insights into the mechanisms of the alpha1b-adrenergic recptor activation

This work compares the structural/dynamics features of the wild-type alb-adrenergic receptor (AR) with those of the D142A active mutant and the agonist-bound state. The two active receptor forms were compared in their isolated states as well as in their ability to form homodimers and to recognize the G alpha q beta 1 gamma 2 heterotrimer. The analysis of the isolated structures revealed that, although the mutation- and agonist-induced active states of the alpha 1b-AR are different, they, however, share several structural peculiarities including (a) the release of some constraining interactions found in the wild-type receptor and (b) the opening of a cytosolic crevice formed by the second and third intracellular loops and the cytosolic extensions of helices 5 and 6. Accordingly, also their tendency to form homodimers shows commonalties and differences. In fact, in both the active receptor forms, helix 6 plays a crucial role in mediating homodimerization. However, the homodimeric models result from different interhelical assemblies. On the same line of evidence, in both of the active receptor forms, the cytosolic opened crevice recognizes similar domains on the G protein. However, the docking solutions are differently populated and the receptor-G protein preorientation models suggest that the final complexes should be characterized by different interaction patterns.

Clinician characteristics, communication, and patient outcome in oncology: a systematic review.

OBJECTIVE: The aim of this study was to review the literature on clinician characteristics influencing patient-clinician communication or patient outcome in oncology. METHODS: Studies investigating the association of clinician characteristics with quality of communication and with outcome for adult cancer patients were systematically searched in MEDLINE, PSYINFO, PUBMED, EMBASE, CINHAL, Web of Science and The Cochrane Library up to November 2012. We used the preferred reporting items for systematic reviews and meta-analyses statement to guide our review. Articles were extracted independently by two of the authors using predefined criteria. RESULTS: Twenty seven articles met the inclusion criteria. Clinician characteristics included a variety of sociodemographic, relational, and personal characteristics. A positive impact on quality of communication and/or patient outcome was reported for communication skills training, an external locus of control, empathy, a socioemotional approach, shared decision-making style, higher anxiety, and defensiveness. A negative impact was reported for increased level of fatigue and burnout and expression of worry. Professional experience of clinicians was not related to communication and/or to patient outcome, and divergent results were reported for clinician gender, age, stress, posture, and confidence or self-efficacy. CONCLUSIONS: Various clinician characteristics have different effects on quality of communication and/or patient outcome. Research is needed to investigate the pathways leading to effective communication between clinicians and patients. Copyright © 2013 John Wiley & Sons, Ltd.

Valproic acid related idiosyncratic drug induced hepatotoxicity in a glioblastoma patient treated with temozolomide.

Glioblastoma patients undergoing treatment with surgery followed by radiation and temozolomide chemotherapy often develop a state of immunosuppression and are at risk for opportunistic infections and reactivation of hepatitis and herpes viruses. We report the case of a 48-year-old glioblastoma patient who developed acute cholestatic hepatitis with hepatic failure during adjuvant treatment with temozolomide and the integrin inhibitor cilengitide. A viral hepatitis was excluded and valproic acid treatment was stopped. Upon normalisation of the liver tests, temozolomide treatment was resumed without perturbation of the liver tests. Valproic acid related idiosyncratic drug induced hepatotoxicity should be considered as a differential diagnosis in glioblastoma patients undergoing adjuvant therapy.

Protease-activated receptor 2 signalling promotes dendritic cell antigen transport and T cell activation in vivo

Rapport de synthèse : Le récepteur activé par protéase de type 2 (PAR2) intervient dans l'inflammation dans divers modèles expérimentaux de maladies inflammatoires et auto-immunes, mais le mécanisme par lequel il exerce cette fonction reste mal compris. PAR2 est exprimé sur des cellules endothéliales et immunitaires et a été impliqué dans la différentiation des cellules dendritiques (DC). Avec leur rôle central dans la réponse immune, les DC pourraient jouer un rôle clef, l'activation de PAR2 à leur surface modulant la réponse immune. Des recherches précédentes ont montré que PAR2 a un effet dans le développement et la maturation des DC de moelle osseuse in vitro, ainsi que dans la promotion de la réponse immune en allergie. Dans cette étude, nous avons évalué l'impact in vivo de l'activation de PAR2 sur les DC et les cellules T dans des souris déficientes en PAR2 (KO) en utilisant un peptide agoniste spécifique du PAR2 (AP2). L'activation de PAR2 a augmenté la fréquence de DC matures dans les ganglions lymphatiques 24 heures après l'administration d'AP2 d'une manière significative. En outre, ces DC avaient une expression augmentée des molécules de co-stimulation CD86 et du complexe majeur d'histocompatibilité type 2 (MHC-II). 48 heures après l'injection d'AP2, nous avons également observé une élévation significative des lymphocytes T CD4+ et CD8+ activés, (CD44+CD62-) dans ces ganglions. Des changements dans le profil d'activation des DC et des cellules T n'ont pas été observés au niveau de a rate. L'influence de la signalisation de PAR2 sur le transport d'antigène aux ganglions lymphatiques inguinaux a été évaluée dans le contexte d'hypersensibilité retardée de type IV. Les souris KO sensibilisées par peinture de la peau avec fluorescéine isothyocyanate (FITC) afin d'induire une hypersensibilité retardée avaient un pourcentage diminué de DC FITC+ dans les ganglions lymphatiques 24 heures après l'application du FITC en comparaison avec les souris sauvages avec le même fond génétique (0.47% vs 0.95% des cellules ganglionnaires totales). En conclusion, ces résultats démontrent que la signalisation de PAR2 favorise et renforce la maturation et le transport d'antigène par des DC .vers les ganglions lymphatiques ainsi que l'activation ultérieure des lymphocytes T, et de ce fait fournissent une explication pour l'effet pro inflammatoire de PAR2 dans les modèles animaux d'inflammation. Une meilleure compréhension de ce mécanisme de modulation du système immun via PAR2 peut s'avérer particulièrement utile pour le développement des vaccins, ainsi que pour la découverte de nouvelles cibles thérapeutiques dans le contexte de l'allergie, l'auto-immunité, et les maladies inflammatoires.

The role of Malt1 proteolytic activity in T cell activation and lymphoma development

Abstract Long term contact with pathogens induces an adaptive immune response, which is mainly mediated by T and B cells. Antigen-induced activation of T and B cells is an important event, since it facilitates the transition of harmless, low proliferative lymphocytes into powerful and fast expanding cells, which can, if deregulated, be extremely harmful and dangerous for the human body. One of the most important events during lymphocyte activation is the induction of NF-xB activity, a transcription factor that controls not only cytokine secretion, but also lymphocyte proliferation and survival. Recent discoveries identified the CBM complex as the central regulator of NF-xB activity in lymphocytes. The CBM complex consists of the three proteins Carma1, Bcl10 and Malt1, in which Carma1 serves as recruitment platform of the complex and Bcl10 as an adaptor to recruit Malt1 to this platform. But exactly how Malt1 activates NF-x6 is still poorly understood. We discovered that Malt1 is a protease, which cleaves its interaction partner Bcl10 upon T and B cell stimulation. We mapped the Bcl10 cleavage site by single point mutations as well as by a proteomics approach, and used this knowledge to design a fluorogenic Malt1 reporter peptide. With this tool were we able to the first time demonstrate proteolytic activity of Malt1 in vitro, using recombinant Malt1, and in stimulated T cells. Based on similarities to a metacaspase, we designed a Malt1inhibitor, which allowed unto investigate the role of Malt1 activity in T cells. Malt1-inhibited T cells showed a clear defect in NF-xB activity, resulting in impaired IL-2 cytokine secretion levels. We also found a new unexpected role for Bcl10; the blockade of Bcl10 cleavage resulted in a strongly impaired capability of stimulated T cells to adhere to the extracellular matrix protein fibronectin. Because of the central position of the C8M complex, it is not surprising that different lymphomas show abnormal expressions of Carma1, Bcl10 and Malt1. We investigated the role of Malt1 proteolytic activity in the most aggressive subtype of diffuse large B cell lymphomas called ABC, which was described to depend on the expression of Carmal, and frequently carries oncogenic Carmal mutations. We found constitutive high Malt1 activity in all tested ABC cell lines visualized by detection of cleavage products of Malt1 substrates. With the use of the Malt1-inhibitor, we could demonstrate that Malt-inhibition in those cells had two effects. First, the tumor cell proliferation was decreased, most likely because of lower autocrine stimulation by cytokines. Second, we could sensitize the ABC cells towards cell death, which is most likely caused by reduced expression of prosurvival NF-xB target gens. Taken together, we identified Malt1 as a protease in T and B cells, demonstrated its importance for NF-xB signaling and its deregulation in a subtype of diffuse large B cell lymphoma. This could allow the development of a new generation of immunomodulatory and anti-cancer drugs. Résumé Un contact prolongé avec des pathogènes provoque une réponse immunitaire adaptative qui dépend principalement des cellules T et 8. L'activation des lymphocytes T et B, suite à la reconnaissance d'un antigène, est un événement important puisqu'il facilite la transition pour ces cellules d'un état de prolifération limitée et inoffensive à une prolifération soutenue et rapide. Lorsque ce mécanisme est déréglé ìl peut devenir extrêmement nuisible et dangereux pour le corps humain. Un des événement les plus importants lors de l'activation des lymphocytes est l'induction du facteur de transcription NFxB, qui organise la sécrétion de cytokines ainsi que la prolifération et la survie des lymphocytes. Le complexe CBM, composé des trois protéines Carmai, Bc110 et Malt1, a été récemment identifié comme un régulateur central de l'activité de NF-x8 dans les lymphocytes. Carma1 sert de plateforme de recrutement pour ce complexe alors que Bc110 permet d'amener Malt1 dans cette plateforme. Cependant, le rôle exact de Malt1 dans l'activation de NF-tcB reste encore mal compris. Nous avons découvert que Malt1 est une protéase qui clive son partenaire d'interaction BcI10 après stimulation des cellules T et B. Nous avons identifié le site de clivage de BcI10 par une série de mutations ponctuelles ainsi que par une approche protéomique, ce qui nous a permis de fabriquer un peptide reporteur fluorogénique pour mesurer l'activité de Malt1. Grâce à cet outil, nous avons démontré pour la première fois l'activité protéolytique de Malt1 in vitro à l'aide de protéines Malt1 recombinantes ainsi que dans des cellules T stimulées. La ressemblance de Malt1 avec une métacaspase nous a permis de synthétiser un inhibiteur de Malt1 et d'étudier ainsi le rôle de l'activité de Malt1 dans les cellules T. L'inhibition de Malt1 dans les cellules T a révélé un net défaut de l'activité de NF-x8, ayant pour effet une sécrétion réduite de la cytokine IL-2. Nous avons également découvert un rôle inattendu pour Bcl10: en effet, bloquer le clivage de Bcl10 diminue fortement la capacité d'adhésion des cellules T stimulées à la protéine fïbronectine, un composant de la matrice extracellulaire. En raison de la position centrale du complexe CBM, il n'est pas étonnant que le niveau d'expression de Carmai, Bcl10 et Malt1 soit anormal dans plusieurs types de lymphomes. Nous avons examiné le rôle de l'activité protéolytique de Malt1 dans le sous-type le plus agressif des lymphomes B diffus à grandes cellules, appelé sous-type ABC. Ce sous-type de lymphomes dépend de l'expression de Carmai et présente souvent des mutations oncogéniques de Carma1. Nous avons démontré que l'activité de Malt1 était constitutivement élevée dans toutes les lignées cellulaires de type ABC testées, en mettant en évidence la présence de produits de clivage de différents substrats de Malt1. Enfin, l'utilisation de l'inhibiteur de Malt1 nous a permis de démontrer que l'inhibition de Malt1 avait deux effets. Premièrement, une diminution de la prolifération des cellules tumorales, probablement dûe à leur stimulation autocrine par des cytokines fortement réduite. Deuxièmement, une sensibilisation des cellules de type ABC à ia mort cellulaire, vraisemblablement causée par l'expression diminuée de gènes de survie dépendants de NF-tcB. En résumé, nous avons identifié Malt1 comme une protéase dans les cellules T et B, nous avons mis en évidence son importance pour l'activation de NF-xB ainsi que les conséquences du dérèglement de l'activité de Malt1 dans un sous-type de lymphome B diffus à larges cellules. Notre étude ouvre ainsi la voie au développement d'une nouvelle génération de médicaments immunomodulateurs et anti-cancéreux.

Reduced Prostasin (CAP1/PRSS8) Activity Eliminates HAI-1 and HAI-2 Deficiency-Associated Developmental Defects by Preventing Matriptase Activation.

Loss of either hepatocyte growth factor activator inhibitor (HAI)-1 or -2 is associated with embryonic lethality in mice, which can be rescued by the simultaneous inactivation of the membrane-anchored serine protease, matriptase, thereby demonstrating that a matriptase-dependent proteolytic pathway is a critical developmental target for both protease inhibitors. Here, we performed a genetic epistasis analysis to identify additional components of this pathway by generating mice with combined deficiency in either HAI-1 or HAI-2, along with genes encoding developmentally co-expressed candidate matriptase targets, and screening for the rescue of embryonic development. Hypomorphic mutations in Prss8, encoding the GPI-anchored serine protease, prostasin (CAP1, PRSS8), restored placentation and normal development of HAI-1-deficient embryos and prevented early embryonic lethality, mid-gestation lethality due to placental labyrinth failure, and neural tube defects in HAI-2-deficient embryos. Inactivation of genes encoding c-Met, protease-activated receptor-2 (PAR-2), or the epithelial sodium channel (ENaC) alpha subunit all failed to rescue embryonic lethality, suggesting that deregulated matriptase-prostasin activity causes developmental failure independent of aberrant c-Met and PAR-2 signaling or impaired epithelial sodium transport. Furthermore, phenotypic analysis of PAR-1 and matriptase double-deficient embryos suggests that the protease may not be critical for focal proteolytic activation of PAR-2 during neural tube closure. Paradoxically, although matriptase auto-activates and is a well-established upstream epidermal activator of prostasin, biochemical analysis of matriptase- and prostasin-deficient placental tissues revealed a requirement of prostasin for conversion of the matriptase zymogen to active matriptase, whereas prostasin zymogen activation was matriptase-independent.

Family physician involvement in cancer care and lung cancer patient emotional distress and quality of life.

PURPOSE: This study aims to describe emotional distress and quality of life (QoL) of patients at different phases of their lung cancer and the association with their family physician (FP) involvement. METHODS: A prospective study on patients with lung cancer was conducted in three regions of Quebec, Canada. Patients completed, at baseline, several validated questionnaires regarding their psychosocial characteristics and their perceived level of FP involvement. Emotional distress [profile of mood states (POMS)] and QoL [European Organization for Research and Treatment of Cancer Quality of Life Core 30 (EORTC QLQ-C30)] were reassessed every 3-6 months, whether patients had metastasis or not, up to 18 months. Results were regrouped according to cancer phase. Mixed models with repeated measurements were performed to identify variation in distress and QoL. RESULTS: In this cohort of 395 patients, distress was low at diagnosis (0.79 ± 0.7 on a 0-4 scale), raising to 1.36 ± 0.8 at the advance phase (p < 0.0001). Patient's global QoL scores significantly decreased from the diagnosis to the advance phase (from 66 to 45 on a 0-100 scale; p < 0.0001). At all phases of cancer, FP involvement was significantly associated with patients' distress (p = 0.0004) and their global perception of QoL (p = 0.0080). These associations remained statistically significant even after controlling for age, gender, and presence of metastases. CONCLUSIONS: This study provides new knowledge on patients' emotional distress and QoL with cancer evolution and, particularly, their association with FP involvement. Other studies should be conducted to further explore FP role in cancer supportive care.
