Chronic Treatment with Somatostatin Analogues in Recurrent Type 1 Gastric Neuroendocrine Tumors.

BACKGROUND: Type 1 gastric neuroendocrine tumors (GC-1) represent an uncommon subtype of neoplasms. Endoscopic resection has been proposed as the treatment of choice; active surveillance may be performed in those smaller than 1 cm, while gastric surgery may be performed for those with frequent recurrences. The antiproliferative effect of somatostatin analogues (SSA) is well known, and their action on GC-1s has been postulated as a chronic treatment to reduce recurrence. METHODS: A two-centered, retrospective, observational study that included nine patients (55.6% women) diagnosed with GC-1, receiving long-term treatment with SSA, with a median follow-up from baseline of 22 months, was undertaken. Endoscopic follow-up, extension study, and analytical values of chromogranin A (Cg A) and gastrin were collected. RESULTS: In total, 88.9% of patients presented partial or complete response. Treatment with SSA was the only independent factor with a trend to prevent tumor recurrence (Odds Ratio 0.054; p = 0.005). A nonsignificant tendency toward a decrease in CgA and gastrin was observed; lack of significance was probably related to concomitant treatment with proton pump inhibitors in some patients. CONCLUSIONS: Chronic treatment with SSA is a feasible option for recurrent GC-1s that are difficult to manage using endoscopy or gastrectomy. Randomized clinical trials to provide more scientific evidence are still needed.

Neuroendocrine Tumor Heterogeneity Adds Uncertainty to the World Health Organization 2010 Classification: Real-World Data from the Spanish Tumor Registry (R-GETNE).

BACKGROUND: Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are a complex family of tumors of widely variable clinical behavior. The World Health Organization (WHO) 2010 classification provided a valuable tool to stratify neuroendocrine neoplasms (NENs) in three prognostic subgroups based on the proliferation index. However, substantial heterogeneity remains within these subgroups, and simplicity sometimes entails an ambiguous and imprecise prognostic stratification. The purpose of our study was to evaluate the prognostic impact of histological differentiation within the WHO 2010 grade (G) 1/G2/G3 categories, and explore additional Ki-67 cutoff values in GEP-NENs. SUBJECTS, MATERIALS, AND METHODS: A total of 2,813 patients from the Spanish National Tumor Registry (RGETNE) were analyzed. Cases were classified by histological differentiation as NETs (neuroendocrine tumors [well differentiated]) or NECs (neuroendocrine carcinomas [poorly differentiated]), and by Ki-67 index as G1 (Ki-67 <2%), G2 (Ki-67 3%-20%), or G3 (Ki-67 >20%). Patients were stratified into five cohorts: NET-G1, NET-G2, NET-G3, NEC-G2, and NEC-G3. RESULTS: Five-year survival was 72%. Age, gender, tumor site, grade, differentiation, and stage were all independent prognostic factors for survival. Further subdivision of the WHO 2010 grading improved prognostic stratification, both within G2 (5-year survival: 81% [Ki-67 3%-5%], 72% [Ki-67 6%-10%], 52% [Ki-67 11%-20%]) and G3 NENs (5-year survival: 35% [Ki-67 21%-50%], 22% [Ki-67 51%-100%]). Five-year survival was significantly greater for NET-G2 versus NEC-G2 (75.5% vs. 58.2%) and NET-G3 versus NEC-G3 (43.7% vs. 25.4%). CONCLUSION: Substantial clinical heterogeneity is observed within G2 and G3 GEP-NENs. The WHO 2010 classification can be improved by including the additive effect of histological differentiation and the proliferation index. IMPLICATIONS FOR PRACTICE: Gastroenteropancreatic neuroendocrine neoplasms are tumors of widely variable clinical behavior, roughly stratified by the World Health Organization (WHO) 2010 classification into three subgroups based on proliferation index. Real-world data from 2,813 patients of the Spanish Registry RGETNE demonstrated substantial clinical heterogeneity within grade (G) 2 and G3 neuroendocrine neoplasms. Tumor morphology and further subdivision of grading substantially improves prognostic stratification of these patients and may help individualize therapy. This combined, additive effect shall be considered in future classifications of neuroendocrine tumors and incorporated for stratification purposes in clinical trials.

[Managing the discharge of diabetic patients from the emergency department: a consensus paper]. / Documento de consenso sobre el manejo al alta desde urgencias del paciente diabético.

EN: Eighty to 90% of patients attended in emergency departments are discharged to home. Emergency department physicians are therefore responsible for specifying how these patients are treated afterwards. An estimated 30% to 40% of emergency patients have diabetes mellitus that was often decompensated or poorly controlled prior to the emergency. It is therefore necessary to establish antidiabetic treatment protocols that contribute to adequate metabolic control for these patients in the interest of improving the short-term prognosis after discharge. The protocols should also maintain continuity of outpatient care from other specialists and contribute to improving the long-term prognosis. This consensus paper presents the consensus of experts from 3 medical associations whose members are directly involved with treating patients with diabetes. The aim of the paper is to facilitate the assessment of antidiabetic treatment when the patient is discharged from the emergency department and referred to outpatient care teams.

ES: El 80-90% de los pacientes atendidos en los servicios de urgencias son dados de alta desde los mismos, y por tanto los facultativos de urgencias son los responsables del tratamiento al alta en dichos pacientes. Se estima que la frecuencia de diabetes mellitus en urgencias es de un 30-40% y en muchos casos dicha diabetes está descompensada o con un mal control metabólico previo, por lo que es necesario establecer pautas de tratamiento antidiabético adecuadas de cara al alta que contribuyan a un adecuado control metabólico de dichos pacientes y favorezca un mejor pronóstico a corto plazo tras el alta, así como mantener una continuidad con la atención ambulatoria por parte de otras especialidades y contribuir a una mejoría del pronóstico a largo plazo. El presente documento es por tanto un consenso de expertos de tres sociedades científicas implicadas directamente en la atención del paciente diabético, que pretende facilitar la valoración del tratamiento al alta desde urgencias en cuanto a la diabetes se refiere y su continuidad asistencial ambulatoria.

Unresectable Recurrent Multiple Meningioma: A Case Report with Radiological Response to Somatostatin Analogues.

Medical treatment of meningiomas is reserved for cases in which surgery and radiotherapy have failed. Given that a high percentage of meningiomas express somatostatin receptors, treatment with somatostatin analogues has been proposed. In addition, these medications have been shown to have an antiproliferative and antiangiogenic effect in vitro. To date, very few cases with clinical response and none with radiological response have been described. The case described here is the first to report a radiological response. A 76-year-old Caucasian male was first diagnosed with unresectable meningioma at age 47. The patient experienced multiple recurrences and underwent three surgeries and radiotherapy over the years from the initial diagnosis. Despite treatment, the disease continued its progression. Based on an Octreoscan positive for tumour uptake, therapy with extended-release somatostatin analogues was started. Although no clinical neurological improvement was observed, magnetic resonance imaging scans revealed a discreet but continuous radiological response over time. After >2 years of continuous administration of lanreotide, the patient remains progression free. In highly selected cases, somatostatin analogue treatment for meningioma may be beneficial. Based on our findings, treatment with somatostatin analogues should be maintained longer than previously described before evaluating treatment response.

INTRODUCCIÓN: Los tumores neuroendocrinos (TNE) representan un grupo de neoplasias originadas por células de la cresta neural y del endodermo con gran heterogenicidad en cuanto a localización, comportamiento clínico, agresividad y pronóstico. El páncreas y el tubo digestivo constituyen las localizaciones más frecuentes. MATERIAL Y MÉTODOS: Se ha realizado una revisión de casos diagnosticados de neoplasia neuroendocrina gastroenteropancreática (TNEGEP), tanto primaria como metastásica, en el Hospital Universitario Clínico San Carlos (HUCSC) entre enero de 2007 y mayo de 2012. Se han comparado los datos obtenidos con los aportados por el Registro del Grupo Español de Tumores Neuroendocrinos (RGETNE). RESULTADOS: El estudio constó de 78 pacientes. El tipo de tumor más común fue el gastroentérico no funcionante. Un 50,6% de los pacientes presentó metástasis al diagnóstico, siendo lo más prevalente la afectación ganglionar. Los TNEGEP localizados en el recto se acompañaron de un mayor porcentaje de metástasis. La supervivencia global a los 24 meses fue del 74,8%, estando en relación con el sexo, la expresión del Ki-67 y la presencia de enfermedad a distancia

INTRODUCTION: Neuroendocrine tumors are a group of neoplasms arising from the neural crest and endoderm and very heterogeneous as regards localization, clinical behavior, aggressiveness, and prognosis. Pancreas and gastrointestinal tract are the most common sites where neuroendocrine tumors can be found. MATERIAL AND METHODS: A review was made of all cases of neuroendocrine tumors diagnosed at Hospital Universitario Clínico San Carlos (HUCSC) from January 2007 to May 2012. Data were compared to the results provided by the Registry of the Spanish Group on Neuroendocrine Tumors (RGETNE). RESULTS: The study cohort comprised 78 patients. Gastroenteric nonfunctional tumors were the most common neoplasms. Metastases were found at diagnosis in 50.6% of patients, with nodal involvement being most prevalent. Tumors located in the rectum were associated to the highestrate of metastasis. Overall 2-year survival rate was 74.8% and was related to sex, Ki-67 expression, and presence of metastasis

Unidades de pie diabético en España: conociendo la realidad mediante el uso de un cuestionario / Diabetic foot units in Spain: Knowing the facts using a questionnaire

OBJETIVO: Conocer el número de unidades de pie diabético (UPD) que existen en España, especialidades que las integran y funcionamiento, así como la cobertura poblacional de las mismas. MATERIAL Y MÉTODOS: El Grupo Español del Pie Diabético (GEPID) elaboró y consensuó un cuestionario basándose en las recomendaciones organizativas para una clínica del pie diabético propuestas por el Consenso Internacional del Pie Diabético (CIPD) 2011. El cuestionario fue enviado desde octubre a diciembre de 2012, a los miembros de 3 sociedades científicas integradas por profesionales implicados en la atención de personas con diabetes mellitus. Se estimó la cobertura poblacional de los centros respondedores y de las UPD usando el censo poblacional 2012. RESULTADOS: Se recibieron 75 cuestionarios, 64 de ellos procedentes de hospitales generales, que supusieron el 13% de los hospitales generales del Sistema Nacional de Salud y se estimó que daban cobertura al 43% de la población censada en España. Respondieron que existía UPD 34 centros, estimándose que daban cobertura a un 25% de la población censada. El número de diferentes profesionales que integran las UPD es de 6,3 ± 2,7 miembros. El análisis del tipo de UPD permitió identificar 3 modelos: mínimo 5 (14,7%), intermedio 20 (58,8%) y de excelencia 9 (26,5%). CONCLUSIONES: El número de UPD comunicadas en este estudio en España es escaso, permitiendo la atención como mucho de uno de cada 4 pacientes con diabetes mellitus. Se precisa mejorar la organización del cuidado del pie diabético en España, mediante la creación de UPD y mejorando las ya existentes

OBJECTIVE: To ascertain the number of diabetic foot units (DFUs) in Spain, the specialists working in them, and the population covered by them. MATERIAL AND METHODS: The Spanish Group on the Diabetic Foot (SGDF) prepared and agreed a questionnaire based on the recommendations of the 2011 International Consensus on the Diabetic Foot (ICDF). From October to December 2012, the questionnaire was sent to members of three scientific societies formed by professionals involved in the care of patients with diabetes mellitus. Population coverage of the responding centers and DFUs was estimated using the 2012 population census. RESULTS: Seventy five questionnaires were received, 64 of them from general hospitals, which accounted for 13% of the general hospitals of the National Health System. It was calculated that they provided coverage to 43% of the population. Thirty four centers answered that they had a DFU. Specialized diabetic foot care was only provided to 25% of the population. The number of different professionals working at diabetic foot units was 6.3 ± 2.7. Classification of DFUs based on their complexity was as follows: 5 basic units (14.7%), 20 intermediate units (58.8%), and 9 excellence units (26.5%). CONCLUSIONS: The number of DFUs reported in this study in Spain is low, and allow for foot care of only one out of every four patients with diabetes. Spanish health system needs to improve diabetic foot care by creating new DFUs and improving the existing ones

Cromogranina A y tumores neuroendocrinos / Chromogranin A and neuroendocrine tumors

La cromogranina A (CgA) es la granina más abundante en los tumores neuroendocrinos gastroenteropancreáticos (TNE-GEP). Como marcador tumoral es moderadamente sensible y poco específico. A pesar de las limitaciones de los métodos de medida que requieren una interpretación cuidadosa, especialmente en el caso de los gastrinomas, pacientes tratados con análogos de somatostatina y tumores pobremente diferenciados, es el mejor marcador tumoral en los TNE-GEP y puede ser útil en otros tumores con diferenciación neuroendocrina. La CgA puede ser usada como marcador en sangre o en muestra tisular mediante inmunohistoquímica. Las concentraciones se relacionan con la carga y la extensión tumoral y puede ser usada en el diagnóstico y seguimiento de los TNE-GEP, especialmente en los derivados del intestino delgado y neuroendocrinos del páncreas. Además es útil como marcador pronóstico en la detección de recidivas y en la monitorización de la respuesta a los distintos tratamientos (AU)

Chromogranin A (CgA) is the most abundant granin in gastroenteropancreatic neuroendocrine tumors (GEP-NETs). As a tumor marker is moderately sensitive and nonspecific. Despite the limitations of testing methods, which require careful interpretation, especially in the case of gastrinomas, patients treated with somatostatin analogues, and poorly differentiated tumors, it is the best tumor marker in GEP-NETs and may be of value in other tumors with neuroendocrine differentiation. CgA may be used as a marker in blood or tissue samples through immunohistochemical techniques. CgA levels correlate with tumor burden and extension and may be used for diagnosis and monitoring of GEP-NETs, especially midgut carcinoids and endocrine pancreatic tumors. It is also useful as a prognostic marker for detection of recurrence and monitoring of response to different treatments (AU)
