ABSTRACT

ABSTRACT Purpose: To explore the role and mechanisms of octreotide in neurofunctional recovery in the traumatic brain injury (TBI) model. Methods: Rats were subjected to midline incision followed by TBI in the prefrontal cortex region. After 72 hours, the behavioural and neurological deficits tests were performed, which included memory testing on Morris water maze for 5 days. Octreotide (15 and 30 mg/kg i.p.) was administered 30 minutes before subjecting to TBI, and its administration was continued for three days. Results: In TBI-subjected rats, administration of octreotide restored on day 4 escape latency time (ELT) and increased the time spent in the target quadrant (TSTQ) on day 5, suggesting the improvement in learning and memory. It also increased the expression of H2S, Nrf2, and cystathionine-γ-lyase (CSE) in the prefrontal cortex, without any significant effect on cystathionine-β-synthase. Octreotide also decreased the TNF-α levels and neurological severity score. However, co-administration of CSE inhibitor (D,L-propargylglycine) abolished octreotide-mediated neurofunctional recovery, decreased the levels of H2S and Nrf2 and increased the levels of TNF-α. Conclusions: Octreotide improved the neurological functions in TBI-subjected rats, which may be due to up-regulation of H2S biosynthetic enzyme (CSE), levels of H2S and Nrf2 and down-regulation of neuroinflammation.

ABSTRACT

Lymphangiomas are rare and correspond to 0.7% to 4.0% of mediastinal tumors, and isolated mediastinal location occurs in 1% of cases. They are benign tumors that originate from a congenital malformation of the lymphatic vessels and are diagnosed more frequently in children less than 2 years of age. Chylous ascites is a clinical manifestation of thoracic duct lymphangioma and is composed of lymph accumulation caused by dilation of this lymphatic channel. It appears milky in the peritoneal cavity, containing triglyceride levels higher than 200 mg/dl. We report the case of a young patient with chylous ascites and lymphangioma of the thoracic duct, who was conservatively treated with octreotide and a low-fat diet with medium-chain triglycerides.

ABSTRACT

ABSTRACT Purpose To explore the role and molecular mechanisms of neuroprotective effects of octreotide in alcohol-induced neuropathic pain. Methods Male Wistar rats were employed and were administered a chronic ethanol diet containing 5% v/v alcohol for 28 days. The development of neuropathic pain was assessed using von Frey hair (mechanical allodynia), pinprick (mechanical hyperalgesia) and cold acetone drop tests (cold allodynia). The antinociceptive effects of octreotide (20 and 40 µg·kg-1) were assessed by its administration for 28 days in ethanol-treated rats. ANA-12 (0.25 and 0.50 mg·kg-1), brain-derived neurotrophic factor (BDNF) receptor blocker, was coadministered with octreotide. The sciatic nerve was isolated to assess the biochemical changes including hydrogen sulfide (H2S), cystathionine β synthase (CBS), cystathionine γ lyase (CSE), tumor necrosis factor-α (TNF-α), BDNF and nuclear factor erythroid 2-related factor 2 (Nrf2). Results Octreotide significantly attenuated chronic ethanol-induced neuropathic pain and it also restored the levels of H2S, CBS, CSE, BDNF, Nrf2 and decreased TNF-α levels. ANA-12 abolished the effects of octreotide on pain, TNF-α, BDNF, Nrf2 without any significant effects on H2S, CBS, CSE. Conclusions Octreotide may attenuate the behavioral manifestations of alcoholic neuropathic pain, which may be due to an increase in H2S, CBS, CSE, BDNF, Nrf2 and a decrease in neuroinflammation.

ABSTRACT

Resumen: Introducción: La hemorragia digestiva por hipertensión portal, sin alternativa de tratamiento endos- cópico o quirúrgico por localizaciones ectópicas, no identificadas del sitio de sangrado o caracterís ticas anatómicas, constituye un desafío terapéutico en Pediatría. El tratamiento habitual incluye la infusión de octreótido endovenoso. En los últimos años, la presentación de octreótido de liberación prolongada (OCT-LAR) para administración mensual intramuscular, resulta una alternativa tera péutica atractiva. Objetivo: Reportar el caso de un lactante con hemorragia digestiva por hiperten sión portal que recibió tratamiento exitoso con OCT-LAR. Caso Clínico: Paciente de 8 meses de vida, con malformación de vena porta extrahepática y episodios reiterados de sangrados digestivos con re querimientos transfusionales e infusiones de octréotido, sin posibilidad de tratamiento endoscópico o quirúrgico. Indicamos OCT-LAR intramuscular mensualmente. Después de diez meses de iniciado el tratamiento, el paciente no repitió sangrados digestivos y no presentó efectos adversos relacionados a la medicación. Conclusión: Consideramos que el reporte de este caso puede resultar de utilidad al presentar una nueva alternativa para el tratamiento de pacientes pediátricos con sangrado digestivo por hipertensión portal sin posibilidades terapéuticas convencionales.


Abstract: Introduction: Upper gastrointestinal bleeding (UGIB) secondary to portal hypertension (PHT), without endoscopic or surgical treatment options due to an ectopic or unidentified bleeding site or the patient's anatomic characteristics, is challenging in pediatric hepatology. The usual treatment in these cases includes intravenous Octreotide. Recently, the availability of long-acting release Octreo tide (OCT-LAR) for monthly intramuscular administration has become an interesting therapeutic alternative. Objective: To report the case of an infant with UGIB due to PHT who was successfully treated with OCT-LAR. Clinical Case: Eight-month-old patient with repeated episodes of UGIB due to extrahepatic portal vein malformation, requiring blood transfusions, and intravenous octreotide infusions. As neither endoscopic nor surgical treatment were feasible, we decided to start IM OCT- LAR monthly. After ten months of treatment, the patient did not present bleeding episodes. No medication-related events were observed. Conclusion: We consider that this report could help in the management of similar pediatric patients with UGIB due to PHT without conventional therapeutic possibilities.

ABSTRACT

@#Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant disease caused by a mutation in the MEN1 gene. We present a 65-year-old man with MEN1 who has primary hyperparathyroidism, microprolactinoma, meningioma and gastrinoma. He had undergone parathyroidectomy followed by tumour excision of meningioma. The duodenal gastrinoma lesion was inoperable as it was close to the superior mesenteric artery with high surgery risk. Medical therapy with octreotide LAR had been initiated and showed good biochemical response as well as disease progression control. Chemoembolization was proposed if the duodenum lesion reduces in size on maintenance treatment with octreotide LAR. This case highlights the challenges in managing this rare condition and octreotide LAR has shown to be effective in controlling the disease progression in MEN1 with inoperable gastrinoma

ABSTRACT

Chylothorax, the accumulation of chyle in the pleural space, is a rare condition, but can lead to serious complications in neonates. Conservative therapy for chylothorax includes enteral feeding with medium-chain triglyceride-enriched diet or parenteral nutrition and administration of octreotide. Surgical management is considered in cases where there is no response to conservative therapy; however, the standardized approach to refractory neonatal chylothorax is still controversial. Chemical pleurodesis can be used when medical therapies for chylothorax fail, to avoid more invasive surgical procedures. We report an extremely preterm infant born at 26 weeks of gestation with refractory chylothorax after patent ductus arteriosus ligation. The infant was successfully treated with pleurodesis using 4% povidone-iodine, without long-term side effects.

ABSTRACT

Acromegaly is a chronic disorder caused by excessive growth hormone (GH) secretion. In most cases, the excess GH originates from GH-producing pituitary adenomas. Surgery is the preferred first-line treatment for patients with acromegaly, but medical management is considered when the disease persists after surgery or in cases where patients refuse surgery or are poor candidates for surgery. Somatostatin analogues are commonly used to treat acromegaly. The Korean Endocrine Society and the Korean Neuroendocrine Study Group have developed a position statement for the use of somatostatin analogues in the medical treatment of acromegaly. This position statement is based on evidence from the current literature and expert opinions. In the case of discrepancies among expert opinions, the experts voted to determine the recommended approach.

ABSTRACT

Pancreaticopleural fistula (PPF) a fistulous connection between the pancreas and pleural space due to prolonged chronic pancreatitis (CP). PPF is a very rare complication which presents in 0.4% of chronic pancreatitis cases, especially among children. We report a case involving a 3-year-old boy who presented with pleural effusion caused by a PPF, a complication of hereditary pancreatitis, which was, for the first time in Korea, successfully managed with endoscopic treatment. Chest radiography and computed tomography showed massive pleural effusion. Percutaneous catheter drainage was performed. High amylase levels were observed in the pleural fluid and serum, suggesting PPF. The patient was managed with bowel rest and octreotide infusion. Endoscopic retrograde cholangiopancreatography revealed CP, and pleural effusion was successfully managed with stent placement. PRSS1 genetic screening revealed R122H mutation.

ABSTRACT

The Korean Endocrine Society (KES) published clinical practice guidelines for the treatment of acromegaly in 2011. Since then, the number of acromegaly cases, publications on studies addressing medical treatment of acromegaly, and demands for improvements in insurance coverage have been dramatically increasing. In 2017, the KES Committee of Health Insurance decided to publish a position statement regarding the use of somatostatin analogues in acromegaly. Accordingly, consensus opinions for the position statement were collected after intensive review of the relevant literature and discussions among experts affiliated with the KES, and the Korean Neuroendocrine Study Group. This position statement includes the characteristics, indications, dose, interval (including extended dose interval in case of lanreotide autogel), switching and preoperative use of somatostatin analogues in medical treatment of acromegaly. The recommended approach is based on the expert opinions in case of insufficient clinical evidence, and where discrepancies among the expert opinions were found, the experts voted to determine the recommended approach.

ABSTRACT

Objetivo: Comparar as modalidades diagnósticas do PET-CT com 68Ga-DOTATATE versus cintilografia em gama camera com 111In-octreotide nos pacientes portadores de tumores neuroendócrinos e a avaliação da medida do seu impacto na mudança de terapia. Método: Quarenta e um pacientes com tumores neuroendócrinos confirmados histologicamente foram incluidos e foram submetidos a cintilografia convencional com 111In-octreotide e PET-CT de corpo inteiro com 68Ga-DOTATATE. Imagens de ambas as modalidades foram comparadas em uma análise paciente a paciente com avaliação do impacto da detecção de lesões adicionais na mudança de conduta. Resultados: Significativamente mais lesões foram detectadas no PET-CT com 68Ga-DOTATATE quando comparado a cintilografia convencional com 111In-octreotide. Lesões adicionais foram mais frequentemente visualizadas no fígado e nos implantes em alças intestinais. Mudanças na conduta devido a informações adicionais oferecidas pelo PET-CT com 68Ga-DOTATATE ocorreram em cinco dos 41 pacientes (12,2%). Três dos 41 pacientes (7,3%) apresentaram mudança de conduta intermodalidade e dois dos 41 (4,9%) mudança intramodalidade. Conclusão: O PET-CT com 68Ga-DOTATATE demonstrou-se superior para a detecção de tumores neuroendócrinos comparativamente à cintilografia convencional com 111In-octreotide, traduzida em parte na mudança de conduta terapêutica


Purpose: Compare the detectability of the 68Ga-DOTATATE PET-CT with conventional 111In-octreotide scintigraphy in neuroendocrine tumors patients carrier and the measure of its impact in therapy change. Method: Forty one patients with a histologically confirmed diagnosis of neuroendocrine tumors were included and underwent conventional 111In-octreotide scintigraphy and whole body 68Ga-DOTATATE PET-CT. Images of both modalities were compared in a patient by patient analysis determining aditional lesions and the impact of detecting additional lesions in the therapy change. Results: Significantly more lesions were detected on 68Ga-DOTATATE PET-CT versus conventional 111In-octreotide scintigraphy. Additional lesions were mostly frequent visualized in liver and implants in intestinal loops. Change in management due additional information given by 68Ga-DOTATATE PET-CT occured in 5 of 41 patients (12.2%). Three of 41 patients (7.3%) presented a intermodality change and 2 of 41 (4.9%) had a intramodality change. Conclusion: 68Ga-DOTATATE PET-CT is superior for the detection of neuroendocrine tumors compared to conventional 111In-octreotide scintigraphy with impact in the therapy change

ABSTRACT

La ascitis quilosa es la acumulación de quilo en la cavidad peritoneal por ruptura u obstrucción de los conductos linfáticos abdominales. Aunque es infrecuente, se describe mayor probabilidad de aparición después de traumas abdominales. Se presenta un paciente masculino de 46 años que sufre herida por arma blanca tóracoabdominal por lo que requirió tratamiento quirúrgico de urgencia. Luego de varias cirugías se constató la presencia de líquido abdominal blanquecino, con triglicéridos elevados. Se confirmó la ascitis quilosa, que se reabsorbió en 45 días con nutrición parenteral y octreótido(AU)


Chylous ascites is the accumulation of lipid-rich lymph in the peritoneal cavity due to rupture or obstruction of the abdominal lymph ducts. Although it is rare, greater probability is described for its onset after abdominal traumas. The case is presented of a 46-year-old male patient who suffers from a thorax-abdomen knife wound and therefore required emergency surgical treatment. After several surgeries, the presence of whitish abdominal liquid was detected, with elevated triglycerides. Chylous ascites was confirmed, which was reabsorbed in 45 days with parenteral nutrition and octreotide(AU)

ABSTRACT

El Bypass Gástrico (BPG) representa la herramienta terapéutica más efectiva para el manejo de la obesidad. Sin embargo, la hipoglucemia con neuroglucopenia post BPG es una complicación que se describe cada vez con mayor frecuencia. Se presenta el caso de una paciente con hipoglucemia hiperinsulinémica (HH) post BPG y los distintos esquemas terapéuticos utilizados, pudiendo controlar finalmente los valores de glucemia con octreótide y evitando así, la realización de una pancreatectomía para el tratamiento de las hipoglucemias


Gastric Bypass (GBP) is the most effective treatment for patients with severe obesity. Hyperinsulinemic hypoglycemia with neuroglycopenia is an increasingly late complication of GBP. A case of a post GBP hyperinsulinemic hypoglycemia is reported, and the different drugs used for its treatment, being able to control the glycemia with octreotide and avoiding a pancreatectomy surgery as hypoglycemia treatment

ABSTRACT

Objective To analyze Ga-DOTA-TATE positron emission tomography/computed tomography (PET/CT) imaging features of tumor-indud osteomalacia (TIO) patients with negative Tc-HYNIC-TOC single photo emission computed tomography (SPECT) findings and to investigate the value of Ga-DOTA-TATE PET/CT in accurate localization of culprit tumors.Methods We retrospectively analyzed Ga-DOTA-TATE PET/CT imaging features including location,size,density,the maximum and mean standardized uptake value in 37 TIO patients with negative Tc-HYNIC-TOC SPECT findings.Results Totally 37 solitary TIO tumors,including 35 phosphaturic mesenchymal tumors and 2 spindle cell tumors confirmed by pathological examinations,were detected via Ga-DOTA-TATE PET/CT scans in the included 37 cases. These 37 TIO tumors showed obviously increased activities,with an maximum standardized uptake value of 7.2±4.3 and mean standardized uptake value of 4.3±2.4. The average maximum diameter was (1.9±0.7) cm. The majority of the tumors occurred in the lower extremities (19/37),followed by the trunk (11/37),maxillary/mandibular bone (5/37),and upper extremities (2/37). In addition,24 bone lesions were located in long bones of lower extremities (13/24),most of which demonstrated eccentric growth (8/13). Osteolytic changes (14/24) were observed mainly in the lesions via the corresponding CT imaging;meanwhile,sclerotic changes presented in nine cases. Of the 13 soft-tissue lesions,the majority (10/13) showed well-circumscribed isodense or hypodense nodules on the CT images,with spot calcification in one lesion located in the pleura.Conclusions Ga-DOTA-TATE PET/CT scans can detect the TIO culprit tumors miss-diagnosed by Tc-HYNIC-TOC SPECT. Somatostatin-receptors highly expressed lesions with focal osteolytic or osteosclerotic change in bone and isodense or hypodense nodules in soft tissue will favor the diagnosis of TIO tumors.

ABSTRACT

@#Introduction: The aim of this study was to investigate the efficacy of resveratrol and octreotide, agents that are used to prevent intra-abdominal adhesions in experimental models, in preventing intraperitoneal adhesions when used alone or in combination. Materials and Methods: The study employed 28 young female Wistar albino rats weighing 250-300 grams. An experimental adhesion model was created in each rat using serosal abrasion and peritoneal excision. They were divided into four groups, each comprising seven rats: Group 1, adhesion induction only; Group 2, resveratrol administration only; Group 3, octreotide administration only; and Group 4, administration of resveratrol and octreotide combination. The rats were monitored under appropriate conditions for 14 days and then underwent laparotomy. Macroscopic intensity and extensiveness of adhesions and microscopic changes in the granulation tissue (cellular intensity, reticular and collagen fibers, capillaries, elastic and smooth muscle fibers, fibrosis) were evaluated and graded. Kruskal-Wallis and Mann-Whitney U-test were used in statistical analysis and the level of statistical significance was established as p <0.05. Results: There was no significant difference between the groups in terms of the intensity and extensiveness of macroscopic adhesions (p=0.377 and p=0.319). There was a statistically significant difference between the microscopic scores of the groups according to Zühlke’s classification (p=0.026). The Bonferroni correction used to test for the differences revealed that the rats in Group 1 achieved significantly higher scores than the rats in Group 3 (p=0.016). Conclusion: Octreotide showed higher efficiency compared to the control group in microscopic classification; however, the two agents were not superior to each other or their combination was not superior in preventing intra-abdominal adhesions.

ABSTRACT

<p><b>BACKGROUND</b>Thyrotropin-secreting pituitary adenomas (TSHomas) are a rare cause of hyperthyroidism. Somatostatin (SST) analogs work by interacting with somatostatin receptors (SSTRs). This study aimed to evaluate short-term preoperative octreotide (OCT) use in TSHoma patients and to investigate SSTR2 and SSTR5 expression and observe structural changes in tumor tissue.</p><p><b>METHODS</b>We reviewed records and samples from eight TSHoma patients treated between July 2012 and July 2015. We tested immunohistochemically for SSTR2/5 expression and examined TSHoma cells for morphological changes. Signed rank sum test was used to compare the efficacy of short-term preoperative OCT treatment.</p><p><b>RESULTS</b>OCT treatment (median time: 7.9 days, range: 3-16 days; median total dose: 1.8 mg, range: 0.9-4.2 mg) led to significant decrease in all patients' thyroid hormone levels (FT3 [nmol/L]: 8.33 [7.02, 12.29] to 4.67 [3.52, 5.37] [P = 0.008]; FT4 [pmol/L]: 25.36 [21.34, 28.99] to 16.66 [14.88, 21.49] [P = 0.016]; and TSH [μU/ml]: 5.80 [4.37, 6.78] to 0.57 [0.19, 1.24] [P = 0.008]). All the eight tumor specimens expressed high SSTR2 protein levels; 5/8 expressed high SSTR5, but 3/8 that expressed low SSTR5 presented a significantly higher TSH suppression rate (P = 0.036). Electron microscopy showed subcellular level impairments, including clumped nuclear chromatin and reduced cytoplasmic volume. Golgi complexes were observed in the OCT-treated TSHoma specimens.</p><p><b>CONCLUSIONS</b>OCT can control hormone levels and damage the ultrastructure of tumor cells and organelles. Short-term response to OCT may be related to SSTR5 expression. Preoperative SST analog treatment for TSHoma could be considered as a combination therapy.</p>

ABSTRACT

INTRODUCCIÓN: Los tumores neuroendocrinos (TNE) también conocidos como tumores carcinoides, constituyen un grupo heterogéneo de tumores, poco frecuentes, ya que representan el 1 al 2% de los tumores digestivos y el 0.19% de los tumores en general. Se originan en células neuroendocrinas con una amplia distribución, incluyendo ganglios y paraganglios, glándulas endocrinas (hipófisis, médula adrenal, páncreas), piel y numerosos órganos con células dispersas (tubo digestivo, tracto biliar, pulmón y bronquios, timo, sistema urogenital). La sobrevida depende principalmente del tamaño tumoral (influido por la velocidad de crecimiento y grado de diferenciación) y la presencia de metástasis. Los principales sitios de metástasis son los ganglios linfáticos del mesenterio, hígado, pulmón y peritoneo. TECNOLOGÍAS SANITARIAS EVALUADAS: Octreotide - Lanreotide - Sunitinib ­ Everolimus. EFICACIA DE LOS TRATAMIENTOS: Al comparar Octreotide versus placebo como terapia antitumoral en pacientes portadores de TNE avanzados, con síndrome de carcinoide, se concluye que Octreotide no disminuye la mortalidad y probablemente se asocia a un mínimo o nulo aumento de los efectos adversos. Por su parte, al comparar Lanreotide con placebo, en pacientes con TNE digestivos avanzados, bien o moderadamente diferenciados se encuentra que Lanreotide probablemente no disminuye la mortalidad y probablemente no se asocia a efectos adversos severos. En el caso de Sunitinib, al compararse versus placebo en pacientes con tumores neuroendocrinos pancreáticos avanzados bien diferenciados, la evidencia señala que Sunitinib disminuye la mortalidad y que los efectos adversos severos fueron menores en los pacientes que recibieron sunitinib. Al comparar Everolimus con placebo en pacientes con TNE avanzados, bien o moderadamente diferenciados, pancreáticos, con enfermedad en progresión, se concluye que Everolimus disminuye la mortalidad y aumentan los efectos adversos severos. Finalmente, al comparar everolimus con placebo en pacientes con TNE avanzados, bien o moderadamente diferenciados, digestivos (no pancreáticos) o pulmonares, con enfermedad en progresión, se puede afirmar que Everolimus no disminuye la mortalidad y aumenta los efectos adversos severos. ANÁLISIS ECONÓMICO: No se encontró evidencia de costo efectividad para lanreotide. En el caso de octreotide sólo se encontró un estudio de costo minimización que fue descartado por el CADTH debido a limitaciones metodológicas. En lo que atañe a sunitinib y everolimus si se encontró evidencia de costo efectividad. En estudio para Canadá, tanto sunitinib y everolimus resultaron ser no costo efectivos dado el umbral de costo efectividad de dicho país. En contraste, en estudios realizados para EE.UU y Reino Unido, los resultados indican que everolimus y sunitinib resultan costo efectivos. En particular, en el caso de Reino Unido everolimus y sunitinib resultan ser costo efectivos para tumores neuroendocrinos pancreáticos y everolimus es costo efectivo para tumores neuroendocrinos pulmonares y gastrointestinales, dado su umbral de costo efectividad. CONCLUSIÓN: Para dar cumplimiento al artículo 28° del Reglamento que establece el proceso destinado a determinar los diagnósticos y tratamientos de alto costo con Sistema de Protección Financiera, según lo establecido en los artículos 7°y 8° de la ley N°20.850, aprobado por el decreto N°13 del Ministerio de Salud, se concluye que el presente informe de evaluación se considera favorable, de acuerdo a lo establecido en el Título III. de las Evaluaciones Favorables de la Norma Técnica N° 0192 de este mismo ministerio.

ABSTRACT

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H₂ blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.

ABSTRACT

INTRODUCCIÓN: Antecedentes: El presente dictamen expone la evaluación de tecnología de la eficacia y seguridad de everolimus en combinación a octreótide, para el tratamiento de pacientes adultos con tumor neuroendocrino pancreático bien diferenciado, sintomáticos, con enfermedad metastásica irresecable sin terapia sistémica previa. Aspectos Generales: Los Tumores neuroendocrinos gastroenteropancreáticos (TNEGEP) representan más del 50% de la totalidad de tumores neuroendocrinos (TNE), constituyéndose en el subgrupo más común (1). Estos tumores surgen de las células neuroendocrinas del sistema gastroenteropancreático y se caracterizan por la expresión de hormonas peptídicas de tipos celulares específicos y marcadores tumorales comunes para todos los TNE (sinaptofisina, cromogranina A). Tecnologia Sanitaria de Interés: Everolimus 10 mg: El Everolimus es un inhibidor de mTOR que se une con alta afinidad a la proteína de unión- FK506 12 (FKBP- 12), formando un complejo que inhibe la activación de mTOR. Esta inhibición reduce la actividad de los efectores de activación, lo que conduce a una obstrucción en la progresión de las células de la fase G1 a la fase S, y posteriormente la inducción de la detención del crecimiento celular y la apoptosis. Everolimus también inhibe la expresión del factor inducible por hipoxia, lo que lleva a una disminución en la expresión del factor de crecimiento endotelial vascular. El resultado de la inhibición de mTOR por everolimus es una reducción en la proliferación celular, la angiogénesis y la captación de glucosa. METODOLOGIA: Se realizó una estrategia de búsqueda sistemática de la evidencia científica con respecto a Everolimus asociado a octreótide en pacientes con TNEP bien diferenciado con enfermedad metastásica irresecable sin terapia sistémica previa. Las siguientes fuentes fueron consultadas y revisadas con la finalidad de encontrar la mejor evidencia disponible: MEDLINE, (PubMed), LILACS (Biblioteca Virtual en Salud - BVS), COCHRANE LIBRARY, Food and Drug Administration (FDA), European Medicines Agency (EMA), National Guideline Clearinghouse (NGC), Ministerio de Salud y Protección Social ­ IETS Colombia,\r\nCMA Infobase de la Canadian Medical Association, Database of Abstracts of Reviews of Effectiveness (DARE). RESULTADOS: Sinopsis de la Evidencia: Se realizó la búsqueda y la revisión. Así se consideraron los estudios que tuvieran como intervención everolimus en combinación a octreótide para el tratamiento de TNEP bien diferenciado, en pacientes sintomáticos con enfermedad metastásica irresecable sin terapia sistémica previa. CONCLUSIONES: La presente evaluación de tecnología sanitaria tuvo por objetivo la evaluación de la eficacia y seguridad de everolimus en combinación a octreótide en comparación con octreótide solo, para el tratamiento de pacientes adultos con tumor neuroendocrino pancreático bien diferenciado, sintomáticos, con enfermedad metastásica irresecable sin terapia sistémica previa. Fueron incluidos un total de 4 publicaciones científicas (1 guía de práctica clínica, 1 revisión sistemática, 1 evaluación de tecnología sanitaria y 1 ensayo clínico). El IETSI no aprueba el uso de everolimus en combinación con octreótide para el tratamiento de pacientes adultos con TNEP bien diferenciado, sintomáticos, con enfermedad metastásica irresecable sin terapia sistémica previa.
