RESUMO

Introduction: Small cell lung cancer (SCLC) comprises 10–15% of all lung cancer cases and is the most aggressive histological type. Survival is poor and the molecular landscape of this disease is extraordinarily complex. The objective of this paper was to perform a Genome-Wide Association Study (GWAS) of this disease using a case–control study specifically designed for small cell lung cancer (SCLC). Methods: Incident cases were consecutively recruited from 8 hospitals from different regions of Spain. Controls were recruited from the same hospitals using a frequency sampling based on age and sex distribution of cases. Biological samples were obtained along with detailed information on cases and controls lifestyle, including tobacco and radon exposure. Results: We included 271 SCLC cases and 557 controls. We found evidence (p-values<10−5) of an association in the complete dataset for several loci, while MAP4 showed a significant association in the gene-based analysis. Pathway analysis suggested that ATR, ATRIP, MCM4, MCM5, ORC4, RPA3 and CDC25A genes have a role on the onset of SCLC. Conclusion: This study provides biological evidence for pathways related to SCLC, offering novel loci for further research. (AU)

RESUMO

This professional exploration delves into the intricate realm of thyroid hormone receptor interactor 13 (TRIP13) and angiopoietin-1 (ANGPT1) within the context of small cell lung cancer (SCLC). Drawing parallels to the precision and teamwork exemplified by football players on the field, we meticulously investigate the expression patterns and correlations of these molecular players in the complex landscape of SCLC. Our study encompassed a cohort of 78 SCLC patients treated at our institution between January 2015 and April 2017. Through rigorous immunohistochemical staining, we scrutinized the expression profiles of TRIP13 and ANGPT1 within tumor tissues, seeking to unravel their associations with clinicopathological characteristics and progression-free survival. Noteworthy findings emerged from our analysis. We observed significantly elevated positive expression rates of TRIP13 in SCLC tissues with lower differentiation levels and liver metastases, highlighting the analogy to football players' precise maneuvers. Similarly, ANGPT1 exhibited markedly increased positive expression rates in cases with larger tumor diameters, lower differentiation, and liver metastases, akin to a coordinated football team's collective effort. Our professional exploration uncovered a compelling positive correlation between the expression levels of TRIP13 and ANGPT1 in SCLC, akin to the synergy seen among football players on the field. This molecular partnership shed light on an intriguing aspect of SCLC's pathophysiology. The impact on progression-free survival time further emphasized the clinical relevance of TRIP13 and ANGPT1 in SCLC. Patients expressing both TRIP13 and ANGPT1 or either molecule alone experienced significantly shorter mean progression-free survival times, akin to the swift tactics and strategies employed by football players in a high-stakes game.

RESUMO

El síndrome de Eaton Lambert es un trastorno de tipo autoinmune que afecta a la unión neuromuscular. Cursa con debilidad muscular proximal y simétrica y en el 60% de los casos se asocia a una neoplasia subyacente. Dado que esta debilidad es de inicio insidioso, los pacientes suelen consultar inicialmente a su especialista de Medicina Familiar y Comunitaria. Reconocer esta entidad es fundamental para el diagnóstico precoz de la enfermedad oncológica ya que habitualmente precede en meses a los síntomas locales derivados de la enfermedad tumoral. El médico o médica de Atención Primaria tiene un papel fundamental en el adelanto diagnóstico y debe realizar una derivación precoz al medio hospitalario para completar el estudio. Presentamos un caso clínico de síndrome de Eaton Lambert paraneoplásico en el contexto de un carcinoma de pulmón de células pequeñas que trata de ilustrar esta cronología y abordar el proceso diagnóstico y terapéutico.(AU)


Eaton Lambert syndrome is an autoimmune disorder that involves the neuromuscular junction. Clinical course includes proximal muscular weakness and symmetry. In 60% of cases this is associated with underlying neoplasia. Given that this weakness is of insidious onset, patients usually initially consult their family doctor. Recognizing this condition is essential for early diagnosis of oncological disease as it usually occurs a few months prior to local symptoms arising from tumour disease. The family doctor plays a crucial role in early diagnosis and should refer early to hospital to complete the study. We report a case study of paraneoplastic Eaton Lambert syndrome in the context of a small cell lung carcinoma that tries to depict this chronology, in addition to tackling the diagnostic and therapeutic process.(AU)

RESUMO

Antecedentes: Estudiar la posible relación entre la expresión inmunohistoquímica del receptor 1 del factor de crecimiento endotelial vascular (VEGFR1) y el valor máximo de captación estandarizada (SUVmáx) de la PET 18F-FDG en pacientes con cáncer de pulmón de células no pequeñas.Material y métodos:El estudio incluyó 39 pacientes con NSCLC (24 carcinomas de células escamosas y 15 adenocarcinomas). Según el estadio clínico, los pacientes se distribuyeron de la siguiente manera: 8 en estadio I, 7 en estadio II, 15 en estadio III y 9 en estadio IV. Se estudió la expresión inmunohistoquímica del VEGFR1 mediante la técnica de la matriz tisular utilizando el dispositivo de arreglo de tejidos (Beecher Instruments, Sun Prairie, WI), utilizando el anticuerpo policlonal contra el VEGFR1 (Santa Cruz Biotechnology, California, EE. UU.).Resultados: Se observó una expresión inmunohistoquímica positiva del VEGFR1 en 23 casos (59%). El número de tumores positivos no se relacionó con el estadio clínico pero hubo una asociación estadísticamente significativa diferente (p: 0,0009) entre la positividad de VEGFR1 y el tipo histológico, correspondiendo los mayores porcentajes de resultados positivos a los adenocarcinomas (93,3%) frente a los carcinomas escamocelulares (37,5%). Asimismo, los valores SUVmáx fueron mayores (p: 0,039) en los carcinomas VEGFR1 negativos que en los tumores VEGFR1 positivos (r: 4-32,1; 16,4+/-6,4 [mediana 16,1] vs. r: 3-47; 14,5+/-8,6 [12,8]).Conclusiones: Nuestros resultados nos llevaron a considerar que en el CPCNP, la expresión inmunohistoquímica negativa de VEGFR1 se asocia significativamente con el subtipo de carcinomas de células escamosas y con valores SUVmáx más altos en 18F-FDG-PET (AU)


Background: To study the possible relation between immunohistochemical expression of vascular endothelial growth factor receptor 1 (VEGFR1) and the maximum standardised uptake value (maxSUV) of 18F-FDG PET in patients with non small cell lung cancer.Material and methods: The study included 39 patients with NSCLC (24 squamous cell carcinomas and 15 adenocarcinomas). According to the clinical stage, the patients were distributed as follows: 8 stage I, 7 stage II, 15 stage III and 9 stage IV. Immunohistochemical expression of VEGFR1 was studied through the technique of tissue-matrix using tissue arrayer device (Beecher Instruments, Sun Prairie, WI), using the polyclonal antibody against VEGFR1 (Santa Cruz Biotechnology, California, USA).Results: Positive VEGFR1 immunohistochemical expression was noted in 23 cases (59%). The number of positive tumours was not related with clinical stage but there was a different statistically significant association (p:.0009) between VEGFR1 positivity and histological type, corresponding the greater percentages of positive results to adenocarcinomas (93.3%) versus in squamous cell carcinomas (37.5%). Likewise, maxSUV values were higher (p: .039) in negative VEGFR1 carcinomas than in positive VEGFR1 tumors (r: 4-32.1; 16.4+/-6.4 [median 16.1] vs. r: 3-47; 14.5+/-8.6 [12.8]).Conclusions: Our results led us to consider that in NSCLC, the negative VEGFR1 immunohistochemical expression is associated significantly with squamous cell carcinomas subtype and with higher maxSUV values in 18F-FDG-PET (AU)

RESUMO

INTRODUCCIÓN: El 85% de los cánceres de pulmón son carcinomas de célula no pequeña (CPCNP) y la mayoría se diagnostican en estadios avanzados. La inmunoterapia ha cambiado el paradigma del tratamiento de estos tumores y la búsqueda de un marcador que seleccione a los pacientes. Actualmente PD-L1 es el biomarcador usado en la práctica clínica, aunque no es un marcador ideal. MATERIAL Y MÉTODOS: Revisión retrospectiva de 53 casos de CPCNP diagnosticados en el Hospital Universitario La Paz entre 2005 y 2007, con reclasificación de los tumores según la clasificación de la OMS 2015, estudio de PD-L1 con los clones 22C3 y 28-8 por dos observadores, valorando la concordancia entre patólogos y entre clones; y correlación de todos los datos estudiados con la supervivencia. RESULTADOS: Encontramos una prevalencia de expresión de PD-L1 en célula tumoral (TC) semejante a la literatura; una concordancia entre clones muy buena en la valoración de TC y de células inmunes (CCI 0,99-0,93; p < 0,001). Una concordancia interobservador muy buena en la evaluación de TC (CCI 0,902; IC 95%: 0,836-0,942; p < 0,001 para el clon 22C3 y CCI 0,927; IC 95%: 0,877-0,957; p < 0,001 para el clon 28-8); y discreta para las células inmunes (CCI 0,413; IC 95%: 0,163-0,613; p = 0,001 con el clon 22C3 y CCI 0,313; IC 95%: 0,053-0,534; p = 0,010 con el clon 28-8). Solo encontramos relación con el pronóstico en subtipo y grado histológico. CONCLUSIONES: Los clones de PD-L1 22C3 y 28-8 son equivalentes y hay buena concordancia interobservador en la valoración de las TC, pero no en la de células inmunes


INTRODUCTION: 85% of lung cancers are non-small cell carcinomas (NSCLC), the majority of which are diagnosed in an advanced stage. Immunotherapy has changed the treatment pattern for these tumors and created the need to find a marker for patient selection. Although not ideal, PD-L1 is the biomarker currently used in clinical practice. MATERIAL AND METHODS: Retrospective review by two pathologists of 53 cases of NSCLC from 2005 to 2007 in Hospital Universitario La Paz, using the WHO 2015 classification studying PD-L1 with clones 22C3 and 28-8. The consistency between observers and clones was assessed and all data studied were correlated with survival rates. RESULTS: We found a prevalence of PD-L1 expression in tumor cells (TC) similar to that previously reported in the literature and a very good consistency between clones in the evaluation of TC and immune cells (ICC 0.99-0.93, p<.001). Interobserver concordance was very good in the evaluation of TC (ICC 0.902, 95% CI: 0.836-0.942, p<.001 for clone 22C3 and ICC 0.927, 95% CI: 0.877-0.957, p<.001 for clone 28-8) and poor for immune cells (ICC of 0.413, 95% CI: 0.163-0.613, p=.001 with clone 22C3 and ICC of 0.313, 95% CI: 0.053-0.534, p=.010 with clone 28-8). Subtype and histological grade were the only variables related to prognosis. CONCLUSIONS: The clones of PD-L1 22C3 and 28-8 are equivalent and there is good interobserver consistency in the evaluation of TC but not in immune cells

RESUMO

OBJETIVO: El propósito del presente estudio es determinar el valor pronóstico de los parámetros metabólicos relacionados con los tumores primarios detectados en los exámenes por tomografía por emisión de positrones/tomografía computarizada (PET/TC) del pretratamiento flúor-18 2-fluoro-2-desoxi-D-glucosa (18F FDG) de pacientes a los que se les ha diagnosticado cáncer pulmonar de células pequeñas (SCLC, por sus siglas en inglés). MATERIALES Y MÉTODOS: En este estudio retrospectivo se inscribieron 63 pacientes con un diagnóstico histopatológicamente confirmado de SCLC a los que se les aplicó un escáner PET/TC con 18F FDG en la línea basal. Se registraron la etapa de la enfermedad, la edad en su diagnóstico, el sexo, el nivel de albúmina y el valor máximo de captación estándar (SUVmax), SUVmean, el volumen de tumor metabólico (MTV) y los valores de glucólisis total de la lesión) relacionados con el tumor primario en el escáner PET de línea basal y se evaluó la relación de estos factores con la supervivencia libre de progresión (PFS) y la supervivencia global (OS). RESULTADOS: El estudio incluyó un total de 63 pacientes (10 mujeres, 53 hombres, con una edad media de 64,8 y un rango de edad de 43-82 años), 22 de los cuales tenía enfermedad limitada (LD) y 41 tenía enfermedad extendida (ED). Los OS y PFS fueron significativamente mayores en pacientes con LD que en pacientes con ED (15+/-2,9 ante 10+/-0,9 meses, p = 0,002 para OS; 10+/- 0,7 ante 6+/-0,6 meses, p = 0,014 para PFS). Sin embargo, no se identificó una relación estadísticamente significativa entre el sexo, el nivel de albúmina, la edad y los niveles SUVmax, SUVmean, MTV y TLG relacionados con el tumor primario y PFS u OS. CONCLUSIÓN: El presente estudio descubrió que los parámetros PET del pretratamiento no tenían valor predictivo para el PFS y OS en pacientes con SCLC


OBJECTIVE: The aim in the present study is to determine the prognostic value of metabolic parameters related to the primary tumors detected in pretreatment Fluorine-18 2-fluoro-2-Deoxy-D-glucose (18F FDG) positron emission tomography/computerized tomography (PET/CT) scans of patients diagnosed with small-cell lung cancer (SCLC). MATERIAL AND METHODS: Enrolled in this retrospective study were 63 patients with a histopathologically confirmed diagnosis of SCLC who underwent an 18F FDG PET/CT scan at baseline. Disease stage, age at diagnosis, gender, albumin level and maximum standardized uptake value (SUVmax), SUVmean, metabolic tumor volume (MTV) and total lesion glycolysis (TLG) values related to the primary tumor at the baseline PET scan were recorded, and the relationship of these factors with progression-free survival (PFS) and overall survival (OS) was evaluated. RESULTS: The study included a total of 63 patients (10 female, 53 male, mean age of 64.8 and age range of 43-82 years), 22 of which had limited disease (LD) and 41 had extensive disease (ED). The OS and PFS were significantly higher in patients with LD than in patients with ED (15+/-2.9 vs. 10+/-0.9 months, p = 0.002 for OS; 10+/- 0.7 vs 6+/-0.6 months, p = 0.014 for PFS). However, no statistically significant relationship was identified between gender, albumin level, age and SUVmax, SUVmean, MTV, TLG values related to the primary tumor and PFS or OS. CONCLUSION: The present study found that pretreatment PET parameters were of not predictive value for PFS and OS in patients with SCLC

RESUMO

Introducción: El cáncer de pulmón de célula pequeña (CPCP) es el tipo histológico más agresivo de las neoplasias broncopulmonares. Representa en torno al 10-15% de todos los casos. Muy pocos estudios han analizado la influencia del radón residencial. Se pretende conocer los factores de riesgo del CPCP. Métodos: Se diseñó un estudio de casos y controles multicéntrico y de base hospitalaria, con 11 hospitales de 4 comunidades autónomas. Resultados: Se analizan los primeros 113 casos reclutados y de ellos 63 con resultados de radón residencial. La edad mediana al diagnóstico fue de 63 años y un 11% de los casos eran menores de 50 años. El 22% de los casos eran mujeres. El 57% tenían enfermedad en estadio IV y el 95% eran fumadores o exfumadores. La concentración mediana de radón residencial era de 128 Bq/m3. Un 8% de los casos tenían concentraciones superiores a 400 Bq/m3. Por sexo, la única diferencia relevante fue en el porcentaje de mujeres nunca fumadoras, más elevado que para los hombres (p < 0,001). La concentración de radón fue superior para los sujetos con enfermedad en estadio IV (diferencias no significativas) y fue más elevada en los pacientes diagnosticados con 63 años o más (p = 0,032). Conclusiones: Existe un diagnóstico a una edad temprana en buena parte de los casos con CPCP y predomina la enfermedad metastásica al diagnóstico. El radón residencial parece jugar un papel importante en la aparición de la enfermedad, existiendo casos diagnosticados con concentraciones de radón muy elevadas (AU)


Introduction: Small cell lung cancer (SCLC) is the most aggressive histologic type of lung cancer, and accounts for approximately 10%-15% of all cases. Few studies have analyzed the effect of residential radon. Our aim is to determine the risk factors of SCLC. Methods: We designed a multicenter, hospital-based case-control study with the participation of 11 hospitals in 4 autonomous communities. Results: Results of the first 113 cases have been analyzed, 63 of which included residential radon measurements. Median age at diagnosis was 63 years; 11% of cases were younger than 50 years of age; 22% were women; 57% had extended disease; and 95% were smokers or former smokers. Median residential radon concentration was 128 Bq/m3. Concentrations higher than 400 Bq/m3 were found in 8% of cases. The only remarkable difference by gender was the percentage of never smokers, which was higher in women compared to men (P < .001). Radon concentration was higher in patients with stage IV disease (non-significant difference) and in individuals diagnosed at 63 years of age or older (P = .032). Conclusions: A high percentage of SCLC cases are diagnosed early and there is a predominance of disseminated disease at diagnosis. Residential radon seems to play an important role on the onset of this disease, with some cases having very high indoor radon concentrations (AU)

RESUMO

Investigaciones recientes sobre la relación entre el sistema inmune y el cáncer han desvelado los mecanismos moleculares mediante los cuales las células neoplásicas aprovechan algunos receptores de los linfocitos T, con función inhibitoria de la respuesta citotóxica, para defenderse del ataque inmune desarrollado frente a ellas. Estos hallazgos han permitido identificar dianas precisas (receptores de los linfocitos T o ligandos que se acoplan a ellos) frente a los que se han diseñado anticuerpos monoclonales, capaces de desbloquear la respuesta inmunitaria. Estos fármacos (immune check point inhibitors), de eficacia demostrada en el melanoma metastásico o el carcinoma renal, han sido probados con éxito frente al carcinoma de pulmón no microcítico en ensayos recientes. Tras su aprobación e incorporación a la práctica clínica en 2.ª línea después de una pauta inicial de quimioterapia (QT), se han comunicado en el último año resultados positivos en ensayos aleatorizados que los comparaban con QT estándar en 1.ª línea. Se han observado respuestas sorprendentes y duraderas, aunque no superan el 20-25% en pacientes no seleccionados, por lo que es crucial detectar rasgos predictivos de eficacia, como el biomarcador PD-L1, si bien los diferentes métodos para su detección han producido resultados dispares. En esta revisión no sistemática se discuten los resultados de los últimos ensayos, las posibilidades de incorporar estos fármacos en primera línea, los criterios de selección de pacientes, los efectos adversos y las perspectivas de su empleo asociados a modalidades terapéuticas tradicionales como QT, radioterapia o antiangiogénicos (AU)


Recent research on the relationship between the immune system and cancer has revealed the molecular mechanisms by which cancer cells co-opt certain T cell receptors which block the cytotoxic response to defend themselves from the antitumor immune attack. These findings have helped identify specific targets (T cell receptors or their corresponding ligands) for the design of monoclonal antibodies that can unlock the immune response. These drugs, known as immune checkpoint inhibitors, have shown efficacy in metastatic melanoma and kidney cancer, and have been successfully tested in non-small cell lung cancer in recent trials. Immune checkpoint inhibitors were included in clinical practice as a second-line option after an initial chemotherapy (CT) regimen, and in the last year positive results have been reported from randomized trials in which they were compared in first line with standard CT. Responses have been surprising and durable, but less than 20%-25% in unselected patients, so it is essential that factors predicting efficacy be identified. One such biomarker is PD-L1, but the different methods used to detect it have produced mixed results. This non-systematic review discusses the results of the latest trials, the possibilities of incorporating these drugs in first-line regimens, the criteria for patient selection, adverse effects, and the prospects of combinations with conventional treatment modalities, such as CT, radiation therapy, and antiangiogenic agents (AU)

RESUMO

Small-cell lung cancer (SCLC) accounts for 13% of all lung tumours. The standard treatment in patients with limited-stage disease is radiotherapy combined with chemotherapy. In extensive SCLC, the importance of consolidation thoracic radiotherapy in patients with a good treatment response has become increasingly recognized. In both limited and extensive disease, prophylactic cranial irradiation is recommended in patients who respond to treatment. New therapeutic approaches such as immunotherapy are being increasingly incorporated into the treatment of SCLC, although more slowly than in non-small cell lung cancer (NSCLC). Diverse radiation dose and fractionation schemes, administered in varying combinations with these new drugs, are being investigated. In the present study we review and update the role of radiotherapy in the treatment of SCLC. We also discuss the main clinical trials currently underway in order to identify future trends (AU)
