Nueva actualización de las recomendaciones para la determinación de biomarcadores predictivos en el carcinoma de pulmón no célula pequeña: Consenso Nacional de la Sociedad Española de Anatomía Patológica y de la Sociedad Española de Oncología Médica / New update to the guidelines on testing predictive biomarkers in non-small-cell lung cancer: a National Consensus of the Spanish Society of Pathology and the Spanish Society of Medical Oncology

El carcinoma de pulmón de no célula pequeña (CPNCP) presenta el mayor número de dianas terapéuticas identificadas, algunas de ellas con utilidad terapéutica. En la actualidad se considera imprescindible en estos pacientes determinar las mutaciones de EGFR, BRAF, KRAS y MET, las traslocaciones de ALK, ROS1, NTRK y RET y la expresión de PD-L1. El uso de la secuenciación masiva (next-generation sequencing [NGS]) facilita el diagnóstico molecular de forma precisa y permite determinar otras mutaciones emergentes, como la mutación de HER2 y los biomarcadores predictivos de respuesta a inmunoterapia. En este consenso, un grupo de expertos en el diagnóstico y tratamiento del CPNCP seleccionado por la Sociedad Española de Anatomía Patológica (SEAP) y la Sociedad Española de Oncología Médica (SEOM) ha evaluado la información actualmente disponible y propone una serie de recomendaciones para optimizar la determinación y utilización en la práctica clínica diaria de los biomarcadores.(AU)

Non-small cell lung cancer (NSCLC) presents the greatest number of identified therapeutic targets, some of which have therapeutic utility. Currently, detecting EGFR, BRAF, KRAS and MET mutations, ALK, ROS1, NTRK and RET translocations, and PD-L1 expression in these patients is considered essential. The use of next-generation sequencing (NGS) facilitates precise molecular diagnosis and allows the detection of other emerging mutations, such as the HER2 mutation and predictive biomarkers for immunotherapy responses. In this consensus, a group of experts in the diagnosis and treatment of NSCLC selected by the Spanish Society of Pathology (SEAP) and the Spanish Society of Medical Oncology (SEOM) have evaluated currently available information and propose a series of recommendations to optimize the detection and use of biomarkers in daily clinical practice.(AU)

A Delphi consensus panel about clinical management of early-stage EGFR-mutated non-small cell lung cancer (NSCLC) in Spain: a Delphi consensus panel study

Purpose This Delphi panel study assessed the level of consensus between medical oncologists on the clinical management of patients with early-stage EGFR-mutated non-small cell lung cancer (NSCLC). Methods A modified two-round Delphi approach was used. A scientific committee comprised of medical oncologists developed an online questionnaire. Delphi panel experts rated their level of agreement with each questionnaire statement on a 9-point Likert scale. The questionnaire included 36 statements from 3 domains (clinical management of early-stage NSCLC: 15 statements; role of adjuvant therapy in early-stage NSCLC: 9 statements; and role of adjuvant therapy in early-stage NSCLC with sensitizing EGFR mutation: 12 statements). Results In round 1, consensus was reached for 24/36 statements (66.7%). Nine statements that did not achieve consensus after the first round were evaluated in round 2, and none of them reached consensus. Overall, 84.4% of the panelists agreed that EGFR mutation testing should be done after surgery. Consensus was not achieved on whether the implementation of EGFR mutation testing in resected early-stage NSCLC could limit the use of adjuvant osimertinib. The panelists recognized the rationale for the use of osimertinib in the adjuvant scenario (88%) and 72% agreed that it may change the treatment paradigm in stage IB–IIIA EGFR-mutated NSCLC. Consensus was not reached on the inconvenience of prolonged duration of osimertinib. Conclusions This Delphi study provides valuable insights into relevant questions in the management of early-stage EGFR-mutated NSCLC. However, specific issues remain unresolved. The expert consensus emphasizes the role of adjuvant treatment with osimertinib in this scenario. (AU)

Actualización de las recomendaciones para la determinación de biomarcadores predictivos en el carcinoma de pulmón de célula no pequeña avanzado. Consenso Nacional de la Sociedad Española de Anatomía Patológica y de la Sociedad Española de Oncología Médica / Updated guidelines for predictive biomarker testing in advanced non-small-cell lung cancer: A National Consensus of the Spanish Society of Pathology and the Spanish Society of Medical Oncology

En el año 2011 se inició un proyecto conjunto entre la Sociedad Española de Oncología Médica (SEOM) y la Sociedad Española de Anatomía Patológica (SEAP) para establecer unas recomendaciones basadas en la evidencia actual con respecto a la determinación de biomarcadores en pacientes con carcinoma de pulmón de célula no pequeña avanzado. Al ser un área en continua evolución, estas recomendaciones se han actualizado previamente en 2012 y 2015, y ahora en 2019. Con la evidencia que existe hoy en día, las determinaciones obligatorias en cualquier paciente con este tipo de carcinoma de pulmón avanzado son las mutaciones de EGFR y BRAF, los reordenamientos de ALK y ROS1, y la expresión de PD-L1. La creciente necesidad que existe para estudiar otros biomarcadores emergentes promueve el uso de forma rutinaria de la secuenciación masiva (next-generation sequencing, NGS). Continúa siendo un reto coordinar a todos los profesionales implicados y priorizar las determinaciones y las tecnologías más adecuadas en cada caso

In 2011, the Spanish Society of Medical Oncology (SEOM) and the Spanish Society of Pathology (SEAP) initiated a joint project to establish guidelines for biomarker testing in patients with advanced non-small-cell lung cancer based on the information available at the time. As this field is constantly evolving, these guidelines were updated in 2012 and 2015 and now in 2019. Current evidence suggests it should be mandatory to test all patients with this kind of advanced lung cancer for EGFR and BRAF mutations, ALK and ROS1 rearrangements and PD-L1 expression. The growing need to study other emerging biomarkers has promoted the routine use of massive sequencing (next-generation sequencing, NGS). However, the coordination of every professional involved and the prioritisation of the most suitable tests and technologies for each case remain a challenge

Hypermethylation of Anti-oncogenic MicroRNA 7 is Increased in Emphysema Patients / La hipermetilación del microrna antioncogénico 7 se encuentra aumentada en pacientes con enfisema

INTRODUCTION: MicroRNA-7 (miR-7) has a suppressive role in lung cancer and alterations in its DNA methylation may contribute to tumorigenesis. As COPD patients with emphysema have a higher risk of lung cancer than other COPD phenotypes, we compared the miR-7 methylation status among smoker subjects and patients with various COPD phenotypes to identify its main determinants. METHODS: 30 smoker subjects without airflow limitation and 136 COPD patients without evidence of cancer were recruited in a prospective study. Clinical and functional characteristics were assessed and patients were classified into: frequent exacerbator, emphysema, chronic bronchitis and asthma COPD overlap (ACO). DNA collected from buccal epithelial samples was isolated and bisulfite modified. miR-7 methylation status was evaluated by quantitative methylation-specific polymerase chain reaction (qMSP). RESULTS: miR-7 Methylated levels were higher in COPD patients than in smokers without airflow limitation (23.7 ± 12.4 vs. 18.5 ± 8.8 %, p = 0.018). Among COPD patients, those with emphysema had higher values of methylated miR-7 (27.1 ± 10.2 %) than those with exacerbator (19.4 ± 9.9 %, p = 0.004), chronic bronchitis (17.3 ± 9.0 %, p = 0.002) or ACO phenotypes (16.0 ± 7.2 %, p = 0.010). After adjusting for clinical parameters, differences between emphysematous patients and those with other phenotypes were retained. In COPD patients, advanced age, mild-moderate airflow limitation, reduced diffusing capacity and increased functional residual capacity were identified as independent predictors of methylated miR-7 levels. CONCLUSION: The increase of miR-7 methylation levels experienced by COPD patients occurs mainly at the expense of the emphysema phenotype, which might contribute to explain the higher incidence of lung cancer in these patients

INTRODUCCIÓN: El microRNA-7 (miR-7) tiene un papel supresor en el cáncer de pulmón, y las alteraciones en la metilación de su DNA podrían contribuir a la tumorogénesis. Como los pacientes con EPOC y enfisema presentan un mayor riesgo de sufrir cáncer de pulmón frente a otros fenotipos de EPOC, comparamos la metilación de miR-7 entre los pacientes fumadores y los pacientes con varios fenotipos de EPOC para identificar sus factores determinantes principales. MÉTODOS: Se reclutaron para un estudio prospectivo 30 sujetos fumadores sin restricciones en el flujo aéreo y 136 pacientes con EPOC sin evidencia de cáncer. Se valoraron las características clínicas y funcionales y se clasificaron a los pacientes en: exacerbaciones frecuentes, enfisema, bronquitis crónica y solapamiento de asma y EPOC (ACO, por sus siglas en inglés). Se recogió ADN a partir de muestras de epitelio bucal, se aisló y se modificó con bisulfito. El estado de metilación del miR-7 se evaluó mediante la reacción cuantitativa en cadena de la polimerasa específica de la metilación (qMPS por sus siglas en inglés). RESULTADOS: Los niveles de metilación del miR-7 fueron más altos en los pacientes con EPOC que en los fumadores sin restricciones en el flujo aéreo (23,7 ± 12,4 frente a 18,5 ± 8,8%, p = 0,018). Entre los pacientes con EPOC, aquellos con enfisema presentaban valores más altos de miR-7 metilado (27,1 ± 10,2%) que aquellos con exacerbaciones (19,4 ± 9,9%, p = 0,004), bronquitis crónica (17,3 ± 9,0%, p = 0,002) o los fenotipos ACO (16,0 ± 7,2%, p = 0,010). Tras ajustar los resultados a los parámetros clínicos, las diferencias entre los pacientes enfisematosos y aquellos con otros fenotipos permanecieron. En los pacientes con EPOC, se identificaron como predictores independientes de los niveles de metilación del miR-7 a: la edad avanzada, limitación al flujo aéreo leve-moderada, capacidad de difusión reducida y capacidad residual funcional aumentada. CONCLUSIÓN: El aumento de los niveles de metilación del miR-7 que experimentan los pacientes con EPOC ocurre principalmente a expensas del fenotipo con enfisema, lo que podría contribuir a explicar la mayor incidencia de cáncer de pulmón en estos pacientes

A Novel Role for the Tumor Suppressor Gene ITF2 in Tumorigenesis and Chemotherapy Response.

Despite often leading to platinum resistance, platinum-based chemotherapy continues to be the standard treatment for many epithelial tumors. In this study we analyzed and validated the cytogenetic alterations that arise after treatment in four lung and ovarian paired cisplatin-sensitive/resistant cell lines by 1-million microarray-based comparative genomic hybridization (array-CGH) and qRT-PCR methodologies. RNA-sequencing, functional transfection assays, and gene-pathway activity analysis were used to identify genes with a potential role in the development of this malignancy. The results were further explored in 55 lung and ovarian primary tumors and control samples, and in two extensive in silico databases. Long-term cell exposure to platinum induces the frequent deletion of ITF2 gene. Its expression re-sensitized tumor cells to platinum and recovered the levels of Wnt/ß-catenin transcriptional activity. ITF2 expression was also frequently downregulated in epithelial tumors, predicting a worse overall survival. We also identified an inverse correlation between ITF2 and HOXD9 expression, revealing that Non-small cell lung cancer (NSCLC) patients with lower expression of HOXD9 had a better overall survival rate. We defined the implication of ITF2 as a molecular mechanism behind the development of cisplatin resistance probably through the activation of the Wnt-signaling pathway. This data highlights the possible role of ITF2 and HOXD9 as novel therapeutic targets for platinum resistant tumors.

Expresión proteica de PD-L1 y datos clínico-patológicos en una cohorte de 53 pacientes con carcinoma de pulmón de célula no pequeña (CPCNP) operados. Concordancia entre clones (22C3 y 28-8) y entre observadores. Correlación y valor pronóstico de datos clínico-patológicos / Protein expression of PD-L1 and clinico-pathological data in a cohort of 53 patients with resectable non small cell lung cancer (NSCLC). Concordance between clones (22C3 and 28-8) and observers. Correlation and prognostic value of clinico-pathological data

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

A survey of perceptions, attitudes, knowledge and practices of medical oncologists about cancer pain management in Spain

Purpose: To monitor oncologists’ perspective on cancer pain management. Methods: An anonymized survey was conducted in two waves. First, over a convenience sample of oncologists known to be particularly concerned with the management of pain. Second, using a random sample of oncologists. Results: In total, 73 and 82 oncologists participated in the first and second wave, respectively. Many oncologists reported to have good knowledge of analgesic drugs (95.9%), the mechanism of action of opioids (79.5%), and good skills to manage opioid-related bowel dysfunction (76.7%). Appropriate adjustment of background medication to manage breakthrough pain was reported by 95.5% of oncologists. Additionally, 87.7% (68.3% in the second wave, p = 0.035) of oncologists reported suitable opioid titration practices, and 90.4% reported to use co-adjuvant medications for neuropathic pain confidently. On the other hand, just 9.6% of oncologists participated in multidisciplinary pain management teams, and merely 30.3 and 27.1% reported to routinely collaborate with the Pain Clinics or involve other staff, respectively. Only 26.4% of the oncologists of the second wave gave priority to pain pathophysiology to decide therapies, and up to 75.6% reported difficulties in treating neuropathic pain. Significantly less oncologists of the second wave (82.9 vs. 94.5%, p = 0.001) used opioid rotation routinely. Conclusions: Unlike in previous surveys, medical oncologists reported in general good knowledge and few perceived limitations and barriers for pain management. However, multi-disciplinary management and collaboration with other specialists are still uncommon. Oncologists’ commitment to optimize pain management seems important to improve and maintain good practices

Actualización de las recomendaciones para la determinación de biomarcadores en el carcinoma de pulmón avanzado de célula no pequeña. Consenso Nacional de la Sociedad Española de Anatomía Patológica y de la Sociedad Española de Oncología Médica / Updated guidelines for biomarker testing in advanced non-small-cell lung cancer. A national consensus of the Spanish Society of Pathology and the Spanish Society of Medical Oncology

En el año 2011 se inició un proyecto conjunto entre la Sociedad Española de Oncología Médica (SEOM) y la Sociedad Española de Anatomía Patológica (SEAP) para establecer unas recomendaciones basadas en la evidencia actual con respecto a la determinación de biomarcadores en pacientes con carcinoma de pulmón de célula no pequeña (CPCNP) avanzado. La mayoría de estas recomendaciones siguen siendo válidas; sin embargo, existen nuevas evidencias que hacen necesaria la actualización de algunos aspectos. En concreto, se modifica la recomendación de qué biomarcadores hay que analizar y en qué pacientes, y se define el manejo óptimo de la muestra tumoral así como las características del material mínimo necesario para la determinación de biomarcadores. Además, se revisan las técnicas adecuadas para la determinación de las mutaciones de EGFR y el reordenamiento de ALK, y se consensúa en qué situaciones se debe llevar a cabo una re-biopsia (AU)

In 2011 the Spanish Society of Medical Oncology (SEOM) and the Spanish Society of Pathology (SEAP) started a joint project to establish guidelines on biomarker testing in patients with advanced non-small-cell lung cancer (NSCLC) based on the current evidence. Most of these guidelines are still valid, but new evidence requires some aspects to be updated. Specifically, the recommendation about which biomarkers to test in which patients is being amended and the best way to manage tumour samples and minimum requirements for biomarker test material are defined. Suitable techniques for testing for EGFR mutations and ALK rearrangement are also reviewed, and a consensus is reached on which situations warrant re-biopsy (AU)

Recomendaciones para la determinación de biomarcadores en el carcinoma de pulmón no microcítico avanzado. Consenso nacional de la Sociedad Española de Anatomía Patológica y de la Sociedad Española de Oncología Médica / No disponible

Actualmente los pacientes con cáncer de pulmón no microcítico (CPNM) avanzado portadores de mutaciones del receptor del factor de crecimiento epidérmico (EGFR), y probablemente en un futuro cercano los pacientes con reordenamientos del gen de la quinasa del linfoma anaplásico (ALK), pueden recibir un tratamiento específico basado en el resultado del análisis de biomarcadores. Esto les proporcionará mayor calidad de vida y supervivencia libre de progresión que la quimioterapia convencional. Este documento de consenso nace como una iniciativa conjunta de la Sociedad Española de Anatomía Patológica (SEAP) y de la Sociedad Española de Oncología Médica (SEOM) y propone recomendaciones diagnósticas y terapéuticas para el paciente con CPNM avanzado basadas en la evidencia científica relacionada con el uso de biomarcadores. Por tanto, supone una oportunidad para mejorar la eficiencia de la actividad asistencial y la utilización de recursos, lo que sin duda redundará en un beneficio para estos pacientes. Aunque este campo está en constante evolución, en la actualidad, con los datos disponibles, este grupo de expertos recomienda que en todos los pacientes con CPNM avanzado de células no escamosas, así como en pacientes no fumadores con independencia del subtipo histológico, se determine el estado mutacional del gen EGFR en un plazo máximo de 7 días a partir del diagnóstico anatomopatológico. Los laboratorios involucrados deben participar en programas de gestión de calidad externos. Por el contrario, los reordenamientos del gen ALK solo se deben analizar en el marco de un ensayo clínico, aunque con los datos tan prometedores que se han obtenido se justificará previsiblemente en un futuro próximo su estudio rutinario en pacientes sin mutaciones de EGFR. Por último, no se considera necesaria la determinación rutinaria de otras anormalidades moleculares en la práctica clínica actual(AU)

Chemotherapy for colorectal cancer in the elderly: Whom to treat and what to use.

The median age at diagnosis of colorectal cancer is during the seventh decade, and the incidence of the disease increases continuously with age. However, as the age increases, the possibilities of receiving adequate cancer treatment diminish and the mortality rises. So, there is a huge need for defined treatment strategies in elderly patients with colorectal carcinoma. The geriatric population is a very heterogeneous group where patients with an excellent health status coexist with the patients with both co-morbidities and functional dependency. Therefore, it is necessary to personalize each treatment according to the degree of vulnerability of the elderly patients. It is essential to set up a multidimensional geriatric assessment in order to consider not only the stage of the disease, but also all the factors that may influence the survival and interfere with the treatment. The aim of this review is to discuss the potential benefits and issues of chemotherapy in the elderly patients affected with colorectal cancer.
