RESUMO
Introduction: Keratoacanthoma (KA) is a group of tumors of epidermal origin with controversial nature. Subungual keratoacanthoma (SUKA) is a rare and destructive variant with more aggressive behavior. SUKA appears as a rapidly growing, painful tumor beneath the nail plate that rapidly progresses to a mass that can measure up to 2 cm. The toe location is unusual. The diagnosis must be made based on the correlation of clinical, radiological, and histopathological findings. Case Presentation: We present two cases of patients diagnosed with SUKAs with different clinical presentations which ranged from very typical to uncommon one. Both cases were treated with simple excision without recurrences. Conclusion: SUKA is a rare subungual tumor. Nail bed location represents a more difficult diagnostic challenge. SUKA should be suspected in the context of persistent and progressive pain on a finger or toe, once more frequent painful tumors have been ruled out.
RESUMO
Resumen El apego es un vínculo afectivo que caracteriza y moldea las relaciones interpersonales cercanas. Los estilos de apego son el conjunto de conocimientos, expectativas e inseguridades que se sostienen sobre el sí mismo y los demás. El objetivo de la presente investigación fue elaborar una escala que evalúe el apego adulto no solo en el contexto romántico, sino con otros significativos, lo que permitirá el estudio de las personas sin pareja. Se realizaron tres estudios: en el estudio uno se realizó un análisis factorial exploratorio (n=400); en el estudio dos un análisis factorial confirmatorio (n=700). Se obtuvo una escala compuesta por 16 reactivos distribuidos en cuatro factores: preocupado, temeroso, evitante y seguro. La varianza explicada fue del 38.09%, con un índice de fiabilidad con un rango de 0.46 a 0.82 en los distintos factores. En el estudio tres se analizó la validez concurrente (n=201). En los tres estudios se encontraron diferencias entre las personas con pareja y sin pareja, puntuando más alto en seguridad las primeras y más alto en apego ansioso aquellas sin pareja. Se obtuvo una escala válida, confiable, culturalmente relevante que evalúa el apego adulto no solo en el ámbito romántico, sino con otros significativos.
Abstract The attachment is an affective bond that characterizes and shapes close interpersonal relationships. Attachment styles are the set of knowledge, expectations and insecurities about oneself and others. The aim of this research was to develop a scale with adequate psychometric properties, that allows to assess adult attachment not only in a romantic context, but with significant others in general. It will allow the study of groups such as single people. To address that aim, three studies were conducted in which men and women form Mexico City participated voluntarily. In study one an exploratory factor analysis was performed (n=400), in study two a confirmatory factor analysis was performed (n=700). As a result of these studies, it was obtained a scale compounded by 16 items distributed in four factors: preoccupied, fearful, dismissing, and secure. The explained variance was 38.09%, with a reliability index of 0.46 to 0.82 in the different factors. In study three concurrent validity was analyzed (n=201). Differences between people with a partner and single were found in the three studies, scoring higher in security the first and single people scoring higher in preoccupied attachment. It was obtained a valid, reliable, and culturally relevant scale to assess adult attachment not only in the romantic ambit, but also in relation to significant others like family and friends.
RESUMO
Resumen La pandemia de COVID-19 es uno de los retos del siglo XXI; la ciencia y la tecnología se pusieron a prueba para desarrollar vacunas, técnicas diagnósticas y tratamientos en tiempo récord. No obstante, la desinformación y mala interpretación han hecho que la seguridad y eficacia de las vacunas contra COVID-19 sean un tema de debate. En esta revisión se abordan conceptos sobre los mecanismos de la inmunización y la vacunación; así como la evidencia que sostiene que las vacunas contra COVID-19 son inmunogénicas, eficaces y seguras.
Abstract The COVID-19 pandemic is one of the challenges of the 21st century; science and technology were put to the test for the development vaccines, diagnostic techniques and treatments in record time. However, misinformation and misinterpretation have made the safety and efficacy of COVID-19 vaccines a subject of debate. This review addresses concepts on immunization mechanisms and vaccination, as well as evidence supporting that COVID-19 vaccines are immunogenic, efficacious and safe.
RESUMO
Resumen El objetivo de la formación doctoral es la generación y difusión de nuevo conocimiento, sin embargo, no es claro cómo los programas de doctorado en Colombia se relacionan con este tipo de producción académica. A partir de ello, en el presente estudio se presenta el panorama general de la producción académica a través de las instituciones de educación superior colombianas que ofertan programas de formación doctoral en psicología. La producción académica se obtuvo de la base de datos Scopus en una muestra de 13 universidades. Tras una búsqueda inicial, se encontraron 1345 documentos, con los cuales se realizó un análisis de los indicadores de productividad y de las redes de colaboración al interior de la disciplina en el país. Posteriormente, esta información se contrastó con la información nacional registrada en el sistema de Curriculum Vitae Latinoamericano y del Caribe (CvLAC) de 193 profesores asociados a las universidades que ofertan los programas de doctorado. Al comparar la producción académica nacional e internacional, se encontró una mayor correlación entre la dirección de tesis de posgrado y la publicación en revistas nacionales. Por lo tanto, se puede afirmar que el impacto de la formación doctoral en la generación de nuevo conocimiento es relativo y tiene un alcance limitado, siendo principalmente las revistas nacionales el medio de difusión de este conocimiento. Se recomienda evaluar el impacto de los productos asociados a la formación posgradual y la visibilidad internacional, con énfasis en las revistas indexadas en bases de datos internacionales.
Abstract The objective of doctoral training is the generation and dissemination of new knowledge; however, it is not clear how doctoral programs in Colombia relate to this type of production. Based on this, this study presents the general panorama of academic production across Colombian higher education institutions that offer doctoral training programs in psychology. The academic production was obtained from the Scopus database in a sample of 13 universities. After this search, 1345 documents were found with which an analysis was made regarding productivity indicators and the collaboration networks within the discipline in the country were identified. Subsequently, this information was contrasted with the national information registered in the Latin American and Caribbean Curriculum Vitae system (CvLAC) of 193 professors associated with the universities offering doctoral programs. As a result, when comparing national and international academic production, a greater correlation is found between the supervision of graduate theses and publication in national journals. In this sense, it is found that the impact of doctoral training on the generation of new knowledge is relative and has a limited scope, being mainly national journals the means of dissemination of this knowledge. It is recommended to evaluate the impact of products associated with postgraduate training and international visibility, with emphasis on indexed journals in international databases.
RESUMO
Objetivo: Avaliar a acuidade visual de crianças da educação infantil em um Centro Municipal de Educação Infantil (CMEI) do município de Teresina-PI. Métodos: Trata-se de uma pesquisa de caráter quantitativo, do tipo observacional, descritivo e transversal. Participaram do estudo 75 pré-escolares que estavam matriculados e frequentando regularmente a CMEI do bairro analisado, de ambos os sexos, na faixa etária de 3 a 6 anos de idade, sendo obtida prévia autorização dos pais/responsáveis. Foi realizada a avaliação da acuidade visual por meio do Teste de Snellen adaptado para a faixa etária estudada. Resultados: Foi constatada baixa acuidade visual em 2 crianças do sexo feminino (2,66%) e 1 criança (1,33%) do sexo masculino, portanto, não havendo diferença expressiva quanto ao sexo. Foram observadas ainda a presença de sinais e sintomas que indicam a necessidade de consulta oftalmológica mais aprofundada em cerca de 7%, devido alterações constatadas não somente pelo Teste de Snellen, mas também pela presença de sinais e sintomas indicativos de encaminhamento como o estrabismo e dor ocular em dois pré-escolares. Conclusões: A avaliação visual realizada permitiu avaliar a acuidade visual dos pré-escolares e assim contribuiu para a possibilidade de um diagnóstico de baixa acuidade visual das crianças avaliadas e seu posterior encaminhamento visando tratamento adequado, refletindo também na conscientização de pais/responsáveis e a necessidade de instituição efetiva de laços que aproximem a Estratégia de Saúde da Família e CMEI.
RESUMO
Because several nail disorders share similar clinical features, their diagnosis and management can be challenging to clinicians. The physical examination may disclose localized abnormalities or point to an underlying systemic disease, requiring additional workup. Furthermore, cosmetic distress and nail-related symptoms (e.g., tingling, stinging, numbness, and pain) are common factors that influence the patient's search for medical assistance. Nail pain (i.e., onychalgia) can accompany both localized and systemic pathology. Onychalgia can be acute or chronic according to the time of evolution; patients may describe it as intermittent or constant, and as a throbbing, burning, sharp, or shooting sensation denoting the nature of the pain. It may be exacerbated by colder temperatures, touch, and increased activity (e.g., manipulating objects, walking). We present four main groups of conditions that might cause nail pain: nail tumors, nail deformities, inflammatory or infectious diseases, and external or traumatic agents. Our article includes an overview of the clinical features, as well as diagnosis and management pearls for each entity. Physicians (dermatologists and nondermatologists) should be aware that abnormalities of the ungual and subungual space are not exclusive of dermatological disorders but may also be present in noncutaneous contexts.

Benign vascular neoplasms are common clinical problems encountered in the practice of primary care. Pyogenic granulomas are one of the most common benign vascular lesions in young adults. Although the physiopathological mechanism for the development of this condition is still not well understood, it has been commonly associated with several triggers such as treatment with retinoids, biological agents, invasive cutaneous therapies and trauma. The development of pyogenic granulomas on sites of vascular malformations like port wine stains has been described in the literature to occur rarely. Most of these types of cases have been studied to occur in the setting of pregnancy and after cryotherapy or pulsated laser therapy. The aim of this article is to present the case of a 21-year-old man with a recent appearance of a pyogenic granuloma within an underlying port wine stain in the posterior cervical region without any history of triggers or risk factors. Excision of the vascular lesion was done, and histopathological report confirmed the diagnosis. The objective of this manuscript is to discuss the possible mechanisms involved in the development of this uncommon presentation and to summarize the current literature related to this clinical scenario.
RESUMO
TP53 mutations are implicated in the progression of mucinous borderline tumors (MBOT) to mucinous ovarian carcinomas (MOC). Optimized immunohistochemistry (IHC) for TP53 has been established as a proxy for the TP53 mutation status in other ovarian tumor types. We aimed to confirm the ability of TP53 IHC to predict TP53 mutation status in ovarian mucinous tumors and to evaluate the association of TP53 mutation status with survival among patients with MBOT and MOC. Tumor tissue from an initial cohort of 113 women with MBOT/MOC was stained with optimized IHC for TP53 using tissue microarrays (75.2%) or full sections (24.8%) and interpreted using established criteria as normal or abnormal (overexpression, complete absence, or cytoplasmic). Cases were considered concordant if abnormal IHC staining predicted deleterious TP53 mutations. Discordant tissue microarray cases were re-evaluated on full sections and interpretational criteria were refined. The initial cohort was expanded to a total of 165 MBOT and 424 MOC for the examination of the association of survival with TP53 mutation status, assessed either by TP53 IHC and/or sequencing. Initially, 82/113 (72.6%) cases were concordant using the established criteria. Refined criteria for overexpression to account for intratumoral heterogeneity and terminal differentiation improved concordance to 93.8% (106/113). In the expanded cohort, 19.4% (32/165) of MBOT showed evidence for TP53 mutation and this was associated with a higher risk of recurrence, disease-specific death, and all-cause mortality (overall survival: HR = 4.6, 95% CI 1.5-14.3, p = 0.0087). Within MOC, 61.1% (259/424) harbored a TP53 mutation, but this was not associated with survival (overall survival, p = 0.77). TP53 IHC is an accurate proxy for TP53 mutation status with refined interpretation criteria accounting for intratumoral heterogeneity and terminal differentiation in ovarian mucinous tumors. TP53 mutation status is an important biomarker to identify MBOT with a higher risk of mortality.

RESUMEN Propósito: La inexistencia de datos a nivel nacional y regional sobre el valor nutricional (VN) de la alimentación ofrecida en comedores comunitarios dirigidos por Organizaciones No Gubernamentales (ONG), que atienden población infantil de zonas urbano marginales, junto con el incremento en la prevalencia de exceso de peso reportada por el Ministerio de Educación Pública de Costa Rica (MEP) en el 2016, justifican el estudio del VN del almuerzo servido a niños(as), que participan en programas de alimentación complementaria en zonas urbano marginales de San José, Costa Rica. Método: Se analizaron mediante muestreo aleatorio 321 platos de almuerzo, durante 12 días en dos comedores. Se reconstruyeron recetas y se determinaron tamaños de porción mediante pesaje directo y se calculó el VN promedio por plato. Resultados: El valor energético fue cercano a la recomendación nutricional. Sin embargo, valores de proteína, grasa total, grasa insaturada, fibra dietética, calcio y potasio fueron inferiores a las recomendaciones y por el contrario, carbohidratos totales, azúcar agregada, grasa saturada y sodio fueron superiores a la recomendación nacional. Conclusión: No es suficiente ofrecer un aporte adecuado de energía. Los excesos y deficiencias de nutrientes reflejan un patrón alimentario obesogénico que suma vulnerabilidad a la condición de pobreza y pobreza extrema de la población infantil de zonas urbano-marginales.
ABSTRACT Purpose: The lack of data at a national and regional level regarding the nutritional value (NV) of the food offered in community feeding programs run by Non-Governmental Organizations, which serve the population of marginal urban areas (an important indicator of infant health), along with the increase in the prevalence of excess weight reported in 2016 by the Ministry of Public Education of Costa Rica, justifies the study of the NV of the lunch served to preschool and school-aged children, who participate in complementary feeding programs in marginal urban areas of San José, Costa Rica. Method: 321 meals served were analyzed over 12 days, in 2 food services. Recipes were reconstructed, and portion sizes were determined by direct weighing of food served and the average NV per dish was calculated. Results: The energy value of the lunch served was similar to the nutritional recommendation. However, for the values of protein, total fat, unsaturated fat, dietary fiber, calcium and potassium which were lower than the nutritional recommendation and on the contrary, the content of total carbohydrates, added sugar, saturated fat and sodium was excessive. Conclusion: It is not enough to offer minors an adequate energy amount. Nutrient excesses and deficiencies reflect an obesogenic food pattern, which adds vulnerability to the condition of poverty and extreme poverty of the child population of marginalized urban areas.

OBJECTIVE: To determine whether analysis of methylated DNA in benign endometrial biopsy (EB) specimens is associated with risk of endometrial cancer (EC). METHODS: We identified 23 women with EBs performed at Mayo Clinic diagnosed as normal (n = 14) or hyperplasia (n = 9) and who later developed endometrial cancer after a median interval of 1 year. Cases were matched 1:1 with patients with benign EBs who did not develop EC (controls) by histology of benign EB (normal endometrium vs. endometrial hyperplasia without atypia), date of EB, age at EB, and length of post-biopsy follow-up. DNA extracted from formalin-fixed paraffin-embedded tissues underwent pyrosequencing to determine percent methylation of promoter region CpGs at 26 loci in 4 genes (ADCYAP1, HAND2, MME, RASSF1A) previously reported as methylated in EC. RESULTS: After pathologic review, 23 matched pairs of cases and controls were identified (14 normal, 9 hyperplasia without atypia per group). Among cases, median time from benign EB to EC was 1 year (range 2 days - 9.2 years). We evaluated 26 CpG sites within 4 genes and found a consistent trend of increasing percentage of methylation from control to case to EC for all CpGs. At the gene-level, mean methylation events of ADCYAP1 and HAND2 in cases were significantly higher than control (p = 0.015 and p = 0.021, respectively). Though the other genes did not reach statistical significance, we observed an increased methylation trend among all genes. Area-under-curve (AUC) calculations (predicting future development of EC in the setting of benign EB) for ADCYAP1 and HAND2 were 0.71 (95% CI 0.55-0.88) and 0.83 (95% CI 0.64-1, respectively). CONCLUSIONS: This proof-of-principle study provides evidence that specific methylation patterns in benign EB correlate with future development of EC.

OBJECTIVE: Mucinous ovarian carcinoma (MOC) is an uncommon ovarian cancer histotype that responds poorly to conventional chemotherapy regimens. Although long overall survival outcomes can occur with early detection and optimal surgical resection, recurrent and advanced disease are associated with extremely poor survival. There are no current guidelines specifically for the systemic management of recurrent MOC. We analyzed data from a large cohort of women with MOC to evaluate the potential for clinical utility from a range of systemic agents. METHODS: We analyzed gene copy number (n = 191) and DNA sequencing data (n = 184) from primary MOC to evaluate signatures of mismatch repair deficiency and homologous recombination deficiency, and other genetic events. Immunohistochemistry data were collated for ER, CK7, CK20, CDX2, HER2, PAX8 and p16 (n = 117-166). RESULTS: Molecular aberrations noted in MOC that suggest a match with current targeted therapies include amplification of ERBB2 (26.7%) and BRAF mutation (9%). Observed genetic events that suggest potential efficacy for agents currently in clinical trials include: KRAS/NRAS mutations (66%), TP53 missense mutation (49%), RNF43 mutation (11%), ARID1A mutation (10%), and PIK3CA/PTEN mutation (9%). Therapies exploiting homologous recombination deficiency (HRD) may not be effective in MOC, as only 1/191 had a high HRD score. Mismatch repair deficiency was similarly rare (1/184). CONCLUSIONS: Although genetically diverse, MOC has several potential therapeutic targets. Importantly, the lack of response to platinum-based therapy observed clinically corresponds to the lack of a genomic signature associated with HRD, and MOC are thus also unlikely to respond to PARP inhibition.

OBJECTIVE: This study is designed to identify genes and pathways that could promote metastasis to the bowel in high-grade serous ovarian cancer (OC) and evaluate their associations with clinical outcomes. METHODS: We performed RNA sequencing of OC primary tumors (PTs) and their corresponding bowel metastases (nâ¯=â¯21 discovery set; nâ¯=â¯18 replication set). Differentially expressed genes (DEGs) were those expressed at least 2-fold higher in bowel metastases (BMets) than PTs in at least 30% of patients (Pâ¯<â¯.05) with no increased expression in paired benign bowel tissue and were validated with quantitative reverse transcription PCR. Using an independent OC cohort (nâ¯=â¯333), associations between DEGs in PTs and surgical and clinical outcomes were performed. Immunohistochemistry and mouse xenograft studies were performed to confirm the role of LRRC15 in promoting metastasis. RESULTS: Among 27 DEGs in the discovery set, 21 were confirmed in the replication set: SFRP2, Col11A1, LRRC15, ADAM12, ADAMTS12, MFAP5, LUM, PLPP4, FAP, POSTN, GRP, MMP11, MMP13, C1QTNF3, EPYC, DIO2, KCNA1, NETO1, NTM, MYH13, and PVALB. Higher expression of more than half of the genes in the PT was associated with an increased requirement for bowel resection at primary surgery and an inability to achieve complete cytoreduction. Increased expression of LRRC15 in BMets was confirmed by immunohistochemistry and knockdown of LRRC15 significantly inhibited tumor progression in mice. CONCLUSIONS: We identified 21 genes that are overexpressed in bowel metastases among patients with OC. Our findings will help select potential molecular targets for the prevention and treatment of malignant bowel obstruction in OC.

Resumen La creciente producción de las revistas de psicología colombianas en las últimas décadas lleva a preguntas sobre la relevancia e impacto regional e internacional de su productividad. Considerando la falta de esfuerzos recientes para evaluar el resultado de estas revistas en diferentes fuentes de información, el presente estudio analizó la producción, colaboración e impacto de las revistas de psicología colombianas entre 2000 y 2016 utilizando información de las siguientes bases de datos: Scopus, Scielo, Redalyc, y Journal Scholar Metrics. Analizamos 3915 artículos publicados en 13 revistas. Se incluyeron las revistas que estaban indexadas en varias de estas bases de datos al tiempo durante el tiempo de observación, lo que permitió realizar comparaciones. Observamos la diversificación y el crecimiento de las revistas en todos los indicadores propuestos, con diferentes grados de visibilidad y calidad según los criterios utilizados. Aunque todas las revistas en general mostraron resultados regionales e internacionales similares, algunas se destacaron en todos los indicadores, lo que a su vez invita a otras revistas a mejorar sus indicadores. Concluimos que la producción colombiana en psicología es visible a nivel regional. Además, las revistas deben aumentar algunos de los indicadores para poder compararlos con otros puntos de referencia de acceso abierto regionales e internacionales, ya que es el modelo bajo el cual se concibieron originalmente.
Abstract The growing output of Colombian psychology journals over past decades leads to questions regarding the regional and international relevance and impact of their productivity. Considering the lack of recent efforts to assess the output of these journals across different information sources, the present study analyzed the production, collaboration, and impact of Colombian psychology journals between 2000 and 2016 using information from the following databases: Scopus, Scielo, Redalyc, and Journal Scholar Metrics. We analyzed 3915 articles published across 13 journals. A journal was included in the analysis if it was indexed in several of these databases, which allowed for multiple comparisons. We observed journals' diversification and growth across all the proposed indicators, with different degrees of visibility and quality depending on the criteria used. Although all the journals generally showed similar regional and international results, some excelled across indicators, which in turn challenges other journals to improve their scores. We conclude that Colombian production in psychology is visible on a regional level. Moreover, journals need to increase some of the indicators so they can be compared with other regional and international open-access benchmarks, which is the model in which they were originally conceived.

RESUMO O objetivo deste estudo foi verificar o efeito do método Pilates (MP) na postura de idosas em uma comunidade. Realizou-se um ensaio clínico controlado, não randomizado, em amostra de 40 idosas de idades entre 60 e 80 anos, divididas igualmente em Grupo Pilates (GP) e Grupo Controle (GC). Os grupos responderam questionário sociodemográfico e foram avaliados, em momentos pré e pós-intervenção, utilizando biofotogrametria, a partir do software SAPO. O GP executou um protocolo de 12 exercícios do MP, duas vezes por semana, durante 50 minutos, por 12 semanas. Realizou-se análise estatística não paramétrica aplicando-se o teste U Mann-Whitney com valor p<0,05 para significância. Os resultados obtidos mostraram que, na visão anterior, no momento antes da intervenção, a distância entre os acrômios, epicôndilos e processo estiloide foram menores no GC, em relação ao GP. Verificou-se que após a intervenção não houve diferença significativa entre os grupos. Na visão posterior observou-se diferença estatisticamente significativa nas variáveis: distância do ângulo superior (p=0,01) e inferior da escápula (p=0,02) do GP em relação ao GC. Concluiu-se que o MP promoveu efeito positivo em algumas variáveis do perfil postural de idosas, podendo ser empregado em grupos de práticas corporais comunitárias.
RESUMEN El objetivo de este estudio ha sido certificar el efecto del método Pilates (MP) en la postura de ancianas en una comunidad. Se ha realizado un ensayo clínico controlado, no aleatorizado, en muestra de 40 ancianas de edades entre 60 y 80 años, divididas igualmente en Grupo Pilates (GP) y Grupo control (GC). Los grupos han respondido cuestionario sociodemográfico y han sido evaluados, en momentos pre y pos intervención, utilizando bio fotogrametría, desde el programa SAPO. El GP ha ejecutado un protocolo de 12 ejercicios del MP, dos veces por semana, durante 50 minutos, por 12 semanas. Se ha realizado el análisis estadístico no paramétrico aplicándose la prueba U Mann-Whitney con valor p<0,05 para significancia. Los resultados que han sido obtenidos han mostrado que, en la visión anterior, en el momento antes de la intervención, la distancia entre los acromios, epicóndilos y proceso estiloide han sido menores en el GC, en relación al GP. Se ha certificado que después de la intervención no hubo diferencia significativa entre los grupos. En la visión posterior se ha observado la diferencia estadísticamente significativa en las variables: la distancia del ángulo superior (p=0,01) e inferior de la escápula (p=0,02) del GP en relación al GC. Se ha concluido que el MP ha promocionado efecto positivo en algunas variables del perfil postural de ancianas, pudiendo ser empleado en grupos de prácticas corporales comunitarias.
ABSTRACT This study aimed to verify the effect of the Pilates method (PM) on the body posture of elderly women in a community. A non-randomized controlled clinical trial was conducted in 40 elderly women aged between 60 and 80 years, divided equally into Intervention Group (IG) and Control Group (CG). The groups answered a sociodemographic questionnaire and were evaluated, in pre- and post-intervention moments, using biophotogrammetry, through the software SAPO. The IG performed a program of 12 Pilates exercises, twice a week, with duration of 50 minutes, for 12 weeks. A nonparametric statistical analysis was performed using Mann-Whitney test with significance value of p<0.05. The results showed before the intervention the distance between the acromions, epicondyles and styloid process were lower in the CG, in relation to the IG; however, after the intervention, no significant difference was observed between the groups. After the intervention, a statistically significant difference was observed in the variables: distance from the superior (p=0.01) and inferior angle of scapula (p=0.02) of the IG in relation to the CG. The conclusion was that Pilates promoted a positive effect on some variables of the postural profile of the elderly women, being suitable for community groups for practice of physical activities.
RESUMO
BACKGROUND: Most pelvic high-grade serous (HGS) carcinomas have been proposed to arise from tubal primaries that progress rapidly to advanced disease. However, the temporal sequence of ovarian and peritoneal metastases is not well characterized. METHODS: To establish the sequence of metastases, phylogenetic relationships among the ovarian and peritoneal carcinomas were determined from single-nucleotide variations (SNVs) in nine tumor regions from each patient with pelvic HGS carcinomas. Somatic SNVs from each tumor sample were used to reconstruct phylogenies of samples from each patient. Variant allele frequencies were used to reconstruct subclone phylogenies in each tumor sample. RESULTS: We show that pelvic HGS carcinomas are highly heterogeneous, only sharing less than 4% of somatic SNVs among all nine carcinoma implants in one patient. TP53 mutations are found in all nine carcinoma implants in each patient. The phylogenetic analyses reveal that peritoneal metastases arose from early branching events that preceded branching events for ovarian carcinomas in some patients. Finally, subclone phylogenies indicate the presence of multiple subclones at each tumor implant and early tumor clones in peritoneal implants. CONCLUSION: The genetic evidence that peritoneal implants arose before or concurrently with ovarian implants is consistent with the emerging concept of the extra-ovarian origin of pelvic HGS cancer. Our results challenge the concept of stepwise spatial progression from the fallopian primary to ovarian carcinomas to peritoneal dissemination and suggest an alternative progression model where peritoneal spreading of early clones occurs before or in parallel with ovarian metastases.
