The clinical significance of inflammatory mediators in predicting obesity and progression-free survival in patients with adult-onset Craniopharyngioma.

BACKGROUND: Craniopharyngioma (CP) is a rare malformational tumor characterized by high rates of recurrence and morbid obesity. However, the role of inflammatory mediators in obesity and the prognosis of patients with CP remains unknown. Therefore, the present study aimed to analyze associations of inflammatory mediators with weight-related outcomes and the prognosis of patients with CP. METHODS: A total of 130 consecutive patients with CP were included in this study. The expression levels of seven inflammatory mediators and the plasma leptin concentration were investigated. Clinical parameters, weight changes, new-onset obesity, and progression-free survival (PFS) were recorded. The relationships between inflammatory mediators, clinicopathologic parameters, weight-related outcomes, and PFS were explored. RESULTS: Compared with those in normal pituitary tissue, the expressions of inflammatory mediators in tumor tissue were higher. Higher expression levels of CXCL1 and CXCL8 were identified as independent risk factors for significant weight gain, and CXCL1 and TNF were identified as independent risk factors for new-onset postoperative obesity. Poor PFS was associated with higher expression levels of CXCL1, CXCL8, IL1A, IL6, and TNF. CONCLUSION: The present study revealed that inflammatory mediators are associated with morbid obesity in patients with CP. Inflammatory mediators may be the critical bridge between elevated leptin and weight-related outcomes. Additionally, PFS was associated with the expression of inflammatory mediators. Further research is needed to elucidate the underlying mechanisms of inflammatory mediators and their potential as targets for novel therapies for CP.

Outcome After Modern Proton Beam Therapy in Childhood Craniopharyngioma: Results of the Prospective Registry Study KiProReg.

PURPOSE: Craniopharyngiomas (CPs) are rare tumors of the sellar region often leading to significant comorbidities due to their close proximity to critical structures. The aim of this study was to analyze survival outcome and late toxicities after surgery and proton beam therapy (PBT) in childhood CPs. METHODS AND MATERIALS: Within the prospective registry study "KiProReg" (DRKS0000536), data of 74 childhood patients with CP, receiving PBT between August 2013 to June 2022 were eligible. Late toxicities were analyzed according to the grading system of the Common Terminology Criteria for Adverse Events, version 4.0. RESULTS: Median follow-up since first diagnosis was 4.3 years (range, 0.8-14.7). In addition, 75.7% of patients received PBT at time of disease progression or recurrence, whereas 24.3% as part of their primary therapy (definitive or adjuvant). Predominantly (85.1%), pencil beam scanning technique was used. The median total dose and initial tumor volume were 5400 cGy relative biologic effectiveness (RBE) and 17.64 cm³ (range, 3.07-300.59), respectively. The estimated (±SE) 3-year overall survival, progression-free, and cystic failure-free survival rate after PBT were 98.2% (±1.7), 94.7% (±3.0), and 76.8% (±5.4), respectively. All local failures (n = 3) were in-field relapses necessitating intervention and occurred exclusively in patients receiving PBT at progression or recurrence. Early cystic enlargements after PBT were typically asymptomatic and self-limiting. Fatigue, headaches, vision disorders, obesity, and endocrinopathies were the predominant late toxicities. No high-grade (≥3) new-onset visual impairment or cognitive deterioration occurred compared with baseline. The presence of cognitive impairments at the end of follow-up correlated with size of the planning target volume (P = .034), Dmean dose to the temporal lobes (P = .032, P = .045) and the number of surgical interventions before PBT (P = .029). CONCLUSIONS: Our findings demonstrate favorable local control rates using modern PBT with acceptable late toxicities. Cyst growth within 12 months after radiation therapy is typically not associated with tumor progression. Longer follow-up must be awaited to confirm results.

Serum Prolactin Levels and Mortality in Adults Without Prolactinoma: A Meta-Analysis.

CONTEXT: Prolactin (PRL) is a highly versatile, multifunctional hormone synthesized and secreted by lactotroph cells of the anterior pituitary. Its metabolic role has been extensively studied even in normoprolactinemic populations. Recently, a wealth of observational data have outlined the potential prognostic value of PRL in various clinical settings. OBJECTIVE: This systematic review aims to systematically evaluate and quantitatively synthesize the association between serum PRL levels and risk of mortality in adults without prolactinoma. METHODS: A systematic literature search was conducted up to June 10, 2023, to identify studies reporting the association of serum PRL levels with clinical outcomes of adults without prolactinoma. A random-effects meta-analysis was conducted to quantify the adjusted hazard ratios [(a)HRs] for all-cause and cardiovascular death (CVD) during follow-up. RESULTS: Twenty-eight studies were deemed eligible reporting the outcomes of adults without prolactinoma, in whom serum PRL levels were measured for risk-stratification. Fourteen studies reported appropriate data for meta-analysis encompassing a total of 23 596 individuals. Each unit of PRL increase was independently associated with increased risk of all-cause (pooled aHR = 1.17 [1.08-1.27]; I2 = 48%) and CV mortality (pooled aHR = 1.54 [1.14-2.09]; I2 = 89%). Individuals belonging to the highest PRL category had significantly higher risk for all-cause (pooled aHR = 1.81 [1.43-2.30]; I2 = 65%) and CV (pooled aHR = 1.59 [1.04-2.42]; I2 = 82%) mortality compared to their lowest-PRL category counterparts. The association between PRL levels and in-hospital death did not reach statistical significance. CONCLUSION: PRL levels seem to be an independent predictor for mortality. Further validation is warranted before its role as a risk-stratification tool can be delineated in clinical practice.

Adenomas hipofisarios en pacientes añosos / Pituitary adenomas in elderly patients

Se evaluó la presentación clínica, tratamiento y sus resultados durante el seguimiento prolongado de 37 pacientes mayores de 65 años con adenomas hipofisarios, y sus causas de muerte. El estudio fue retrospectivo y transversal. La prevalencia de incidentalomas fue 43% (16), macroadenomas 70.3% (26) y adenomas gigantes 16.2% (6). El fenotipo tumoral más frecuente fue el adenoma no funcionante (76%). La prevalencia de alteraciones en el campo visual y síntomas neurológicos fue 56% y 57% respectivamente. El 54% tuvo función hipofisaria normal, deficiencia parcial el 30% y panhipopituitarismo el 16%. Fueron tratados 32, 5 se perdieron en el seguimiento sin recibir tratamiento. Indicamos cirugía en 18. De los operados por vía transesfenoidal, el 23% tuvo complicaciones postquirúrgicas y el 54% mejoría del campo visual. Por vía transcraneal el 50% sufrió complicaciones post quirúrgicas y el 33% mejoró el campo visual. Durante el seguimiento (55.1 ± 48.7 meses) no observamos recrecimiento tumoral, excepto en un adenoma gigante. Cuatro pacientes operados murieron, dos por causas al tumor. Catorce no fueron operados, 11 con adenomas no funcionantes y campo visual normal fueron controlados periódicamente y 3 con adenomas funcionantes recibieron tratamiento médico. No observamos crecimiento tumoral durante el seguimiento (43.7 ± 38.1 meses). No observamos crecimiento tumoral en adenomas no funcionantes y campo visual normal, por lo que sugerimos conducta expectante y control periódico. Cuando existe alteración del campo visual, la cirugía transesfenoidal es segura y efectiva. En los adenomas secretantes y dependiendo de las comorbilidades, sería apropiado optar por tratamiento médico.

Clinical presentation, treatment and its results were evaluated during long-term follow-up of 37 patients older than 65 years with pituitary adenoma. Causes of death were also evaluated. It was a retrospective and cross-sectional study. Prevalence of incidentalomas was 43% (16), macroadenomas 70.3% (26) and giant adenomas 16.2% (6). The most frequent tumor phenotype was the non-functioning adenoma (76%). The prevalence of visual field defects and neurological symptoms was 56% and 57% respectively. We found normal pituitary function in 54%, partial deficiency in 30% and panhypopituitarism in 16%. Thirty-two patients were treated, 5 were lost to follow-up without receiving treatment. Surgery was indicated in 18. Of those operated by trans-sphenoidal approach, 23% had postsurgical complications and 54% improved the visual field. By trans-craneal approach, 50% had post-surgical complications and 33% visual field improvement. During follow-up (55.1 ± 48.7 months) no tumor regrowth was observed, except in a giant adenoma. Four operated patients died, two due to causes related to tumor. Fourteen were not operated, 11 with non-functioning adenoma and normal visual field were periodically controlled and 3 with secreting adenomas received medical treatment. No tumor growth was observed during follow-up (43.7 ± 38.0 months). We did not observe tumor progression in elderly patients with non-functioning adenoma and normal visual field, so we suggest watchful approach and periodic control. When there are visual field defects, trans-sphenoidal surgery can be considered safe and effective. In secreting adenomas and depending on the associated comorbidities, medical treatment would be the appropriate approach.

Abordaje transcalloso de craneofaringioma supraselar / Carniopharyngioma suprasellar transcallosal approach

El craniofaringioma es una neplasia epitelial benigna usualmente de origen supraselar, considerado un tumor hipofisiario de crecimiento lento, puede causar varios grados de hipopituitarismo. En este artículo se describe un caso manejado en el Hospital Dr. Patrocinio Peñuela Ruíz (IVSS) y se realiza una revisión bibliográfica acerca de la presentación, patología y tratamiento. Escolar masculino de 8 años, inicia enfermedad de 1 mes de evolución caracterizada por cefalea frontal de moderada intensidad, disminución de la agudeza visual, movimientos reiterativos a predominio de hemicuerpo derecho. En una primera intervención se coloca válvula de derivación ventrículo peritoneal por hidrocefalia obstructiva: al mes y medio se realizó exéresis completa del tumor mediante abordaje transcalloso. La evolución postoperatoria fue de difícil manejo por presentar alteraciones metabólicas e hidroelectrolíticas. En RMN se evidencia ausencia total del tumor. El trastorno hidroelectrol¡tico se mantuvo a pesar del tratamiento médico: 24 días después del acto quirúrgico, fallece por hipernatremia incohercible. La lesión apareció en nuestro paciente a los 8 años, como una tumoración de 6 por 4 cm. La clínica se presenta 1 mes antes de su ingreso, caracterizada por cefalea, trastornos visuales, movimientos repetitivos a predominio de hemicuerpo derecho sin alteraciones endocrinas al momento del diagnóstico. Mediante abordaje quirúrgico transcalloso se pudo resecar totalmente una tumoración que histopatológicamente determinó un adamantinoma. Sin embargo, el manejo multidisciplinario es condición sine cua non para terminar de lograr el éxito quirúrgico en cirugías tan d¡fíciles como la del paciente.
