Resumo: | To determine the main factors influencing the biological behavior of 40 squamous cell carcinomas (SCC) of the upper digestive tract (UDT) of cattle associated with spontaneous ingestion of bracken fern (Pteridium aquilinum), morphological, including cell proliferation, and immunohistochemical aspects were studied. The aspects analyzed included anatomical localization of SCCs, degree of differentiation, occurrence and distribution of metastasis, intensity of the lymphoplasmocytic inflammatory infiltrate (LPII), of the desmoplastic reation, tumor-associated tissue eosinophilia, and the cell proliferation index evaluated through quantification of the argyrophilic nucleolar organizer regions (AgNORs). Forty two percent of SCCs were in the cranial region, 12.5% in the middle, and 45% in the caudal region of the UDT. The neoplasms were classified as well differentiated (WD-SCC; 67.5%), moderately differentiated (MD-SCC; 20%), or poorly differentiated (PD-SCC; 12.5%). When the degree of differentiation was correlated to the anatomical localization, it was observed in the cranial region that 88.2% were WD-SCC and 11.8% were MD-SCC. In the middle region, 60% were WD-SCC, 20% were MD-SCC, and 20% were PD-SCC. In the caudal region, 50% were WD-SCC, 27,8% were MD-SCC, and 22,2% were PD-SCC. Metastasis occurred in 57.75% of the cases, mostly to regional lymph nodes, and were observed in 58.82% of the cases with SCCs of the cranial region; in 40% of the middle region, and in 61.11% of the caudal region. Metastasis to regional lymph nodes and/or to distant organs were found in 44.44% of WDSCC, 75% of MD-SCC, and 100% of PD-SCC. Migration and invasion patterns were analyzed through the immunohistochemistry technique for cytokeratin. Islands and ribbons of neoplastic keratinocytes predominated in the WD-SCCs. The patterns varied greatly in the MD-SCCs, although small aggregates, ribbons, and cords predominated. PD-SCCS were characterized by small aggregates and individual cells. Lymphatic or hematogenous invasion were detected in 11/40 SCCs. There were SCCs originating from the ductal epithelium of the salivary glands. This finding was not previously reported. The intensity of the LPII was more accentuated in the BD-SCCs than in the MDs or PDs. The intensity of the desmoplastic reaction was quantified through the immunohistochemistry technique for vimentin, and was more severe in the PD-SCCs. The tumor-associated tissue eosinophilia (TATE) was measured in the SCCs and classified as mild, moderate, or severe. The only positive statistically significant association was established between TATE and LPII intensities. Cell proliferation was evaluated through quantification of the argyrophilic nucleolar organizer regions (AgNORs) on the neoplastic keratinocytes. AgNOR mean value and standard deviation (±sd) for WD-SCCs were 1.65 (±0.23), for MD-SCCs were 1.88 (±0.31), and for PD-SCCs were 2.39 (±0.26). The correlation between the AgNOR index and each histopathological grade was statistically significant. In conclusion, the factors which influenced the biological behavior of SCCs were the degree of cell differentiation, the patterns of migration and invasion, the intensity of LPII, TATE and desmoplastic reation, and the cell proliferation index measured through quantification of the AgNORs. |

Os aspectos analisados incluíram localização anatômica dos CCEs, grau de diferenciação celular, ocorrência e distribuição de metástases, padrões de migração e invasão, intensidade do infiltrado inflamatório linfoplasmocítico (IILP), da reação desmoplásica e da eosinofilia tecidual associada a tumores (TATE), e o índice de proliferação celular avaliado através da contagem das regiões organizadoras nucleolares argirofílicas (AgNORs). Quanto a localização anatômica, 42% dos CCEs localizaramse na região cranial, 12,5% na média e 45% na caudal do trato alimentar superior (TAS). Os CCEs foram classificados quanto ao grau de diferenciação celular em bem (CCE-BD [67,5%]), moderadamente (CCE-MD [20%]) ou pouco diferenciados (CCE-PD [12,5%]). Quando relacionado o grau de diferenciação celular com a localização no TAS, verificou-se que na região cranial 88,2% eram CCEs-BD e 11,8% eram MD; na região média, 60% eram BD, 20% eram MD e 20% eram PD; na região caudal, 50% eram BD, 27,8% MD e 22,2% PD. Metástases ocorreram em 57,75% dos casos, principalmente para linfonodos regionais, e foram observadas em 58,82% dos CCEs na região cranial, em 40% dos da região média e em 61,11% dos da região caudal. Metástases para linfonodos regionais e/ou órgãos distantes foram encontradas em 44,44% dos CCEs-BD, em 75% dos MD e em 100% os PD. Foram analisados os padrões de migração e invasão com o auxílio da técnica de imunoistoquímica para citoqueratina. Nos CCEs-BD predominaram os padrões em ilhas e fitas de queratinócitos neoplásicos; nos MD os padrões variaram muito porém predominaram os agregados pequenos, fitas e cordões; nos PD predominaram os agregados e as células individuais. Invasão vascular linfática e/ou sangüínea foram observadas em 11/40 CCEs. Foram observados CCEs originando-se do epitélio dos ductos das glândulas salivares, aspecto este que não havia sido relatado anteriormente. Observou-se que a intensidade do IILP era muito mais acentuada nos CCEs-BD que nos MD e PD. A intensidade da reação desmoplásica foi quantificada através da imunistoquímica para vimentina e foi muito mais acentuada nos CCEs-PD. A TATE foi medida nos CCEs quanto à intensidade em leve, moderada ou acentuada. A única associação positiva estatisticamente significativa foi estabelecida entre a intensidade da TATE e a do IILP. A proliferação celular foi avaliada quantitativamente através da contagem das regiões organizadoras nucleolares argirofílicas (AgNORs) nos queratinócitos neoplásicos. A média e o desvio padrão (±DP) de AgNORs nos CCEs BD foi de 1,65 (±0,23), nos MD de 1,88 (±0,31) e nos PD foi de 2,39 (±0,26). A correlação entre o índice de AgNOR e cada grau de diferenciação celular foi estatisticamente significativa. Concluiu-se que os fatores que influenciaram no comportamento biológico dos CCEs foram o grau de diferenciação celular, os padrões de migração e invasão, a IILP, a TATE e da reação desmoplásica e o índice de proliferação celular avaliado através da contagem das AgNORs.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Medicina VeterináriaUFSMBRMedicina VeterináriaPlantas tóxicasPteridium aquilinumCarcinomas de células escamosasNeoplasmas alimentaresAgNORImunoistoquímicaDoenças de bovinosPatologiaPoisonous plantsPteridium aquilinumSquamous cell carcinomaAlimentary neoplasmsAgNORImunohistochemistryCattle diseasesPathologyCNPQ::CIENCIAS AGRARIAS::MEDICINA VETERINARIAMorfologia e imunoistoquímica dos carcinomas de células escamosas alimentares associados ao consumo de Pteridium aquilinum em bovinosMorphology and immunohistochemistry of alimentary squamous cell carcinoma associated with Pteridium aquilinum in cattleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisKommers, Glaucia Denisehttp://lattes.cnpq.br/5818649889964582Barros, Claudio Severo Lombardo dehttp://lattes.cnpq.br/4788564533191301Schild, Ana Lucia Pereirahttp://lattes.cnpq.br/1712864316987104http://lattes.cnpq.br/8396003665895028Masuda, Eduardo Kenji500500000007400500500500500432feb45-3af7-4769-84f8-44f81f48e8a7c231bbc4-f2c5-4ed1-9d68-412c6b4ab836b0bd8378-1426-4f6d-9f7c-10b073f0f8ab6b8edf2d-e4f1-479f-a14f-d5a5ce30835binfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALEDUARDOKENJIMASUDA1.pdfapplication/pdf8665199http://repositorio.ufsm.br/bitstream/1/10024/1/EDUARDOKENJIMASUDA1.pdf0aa7651fd2afe46f81e62d5f695ac08eMD51EDUARDOKENJIMASUDA2.pdfEDUARDOKENJIMASUDA2.pdfapplication/pdf19396454http://repositorio.ufsm.br/bitstream/1/10024/4/EDUARDOKENJIMASUDA2.pdf6b2faa19dc3267901a1ab248b9b2ee47MD54EDUARDOKENJIMASUDA3.pdfEDUARDOKENJIMASUDA3.pdfapplication/pdf28599947http://repositorio.ufsm.br/bitstream/1/10024/5/EDUARDOKENJIMASUDA3.pdfbbec0d300674c73d70bf8cdd0057a4e3MD55TEXTEDUARDOKENJIMASUDA1.pdf.txtEDUARDOKENJIMASUDA1.pdf.txtExtracted texttext/plain142823http://repositorio.ufsm.br/bitstream/1/10024/2/EDUARDOKENJIMASUDA1.pdf.txt88ede2702c1b4209eba83ce6f0d3d744MD52EDUARDOKENJIMASUDA2.pdf.txtEDUARDOKENJIMASUDA2.pdf.txtExtracted texttext/plain14889http://repositorio.ufsm.br/bitstream/1/10024/6/EDUARDOKENJIMASUDA2.pdf.txtfe463439961d368084034bd8d57d415fMD56EDUARDOKENJIMASUDA3.pdf.txtEDUARDOKENJIMASUDA3.pdf.txtExtracted texttext/plain64453http://repositorio.ufsm.br/bitstream/1/10024/8/EDUARDOKENJIMASUDA3.pdf.txtfd5007e4e5cbfd3d4a8c0a92ead14168MD58THUMBNAILEDUARDOKENJIMASUDA1.pdf.jpgEDUARDOKENJIMASUDA1.pdf.jpgIM Thumbnailimage/jpeg5113http://repositorio.ufsm.br/bitstream/1/10024/3/EDUARDOKENJIMASUDA1.pdf.jpg0940d796360d4685a7cc6c173bd523a1MD53EDUARDOKENJIMASUDA2.pdf.jpgEDUARDOKENJIMASUDA2.pdf.jpgIM Thumbnailimage/jpeg7341http://repositorio.ufsm.br/bitstream/1/10024/7/EDUARDOKENJIMASUDA2.pdf.jpge9bc164feb2fb7bb870aac5e21ae96c8MD57EDUARDOKENJIMASUDA3.pdf.jpgEDUARDOKENJIMASUDA3.pdf.jpgIM Thumbnailimage/jpeg4306http://repositorio.ufsm.br/bitstream/1/10024/9/EDUARDOKENJIMASUDA3.pdf.jpgae12da18e2b9bb28b63bca19ba1834e4MD591/100242023-01-24 09:59:07.835oai:repositorio.ufsm.br:1/10024Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2023-01-24T12:59:07Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |

To determine the main factors influencing the biological behavior of 40 squamous cell carcinomas (SCC) of the upper digestive tract (UDT) of cattle associated with spontaneous ingestion of bracken fern (Pteridium aquilinum), morphological, including cell proliferation, and immunohistochemical aspects were studied. The aspects analyzed included anatomical localization of SCCs, degree of differentiation, occurrence and distribution of metastasis, intensity of the lymphoplasmocytic inflammatory infiltrate (LPII), of the desmoplastic reation, tumor-associated tissue eosinophilia, and the cell proliferation index evaluated through quantification of the argyrophilic nucleolar organizer regions (AgNORs). Forty two percent of SCCs were in the cranial region, 12.5% in the middle, and 45% in the caudal region of the UDT. The neoplasms were classified as well differentiated (WD-SCC; 67.5%), moderately differentiated (MD-SCC; 20%), or poorly differentiated (PD-SCC; 12.5%). When the degree of differentiation was correlated to the anatomical localization, it was observed in the cranial region that 88.2% were WD-SCC and 11.8% were MD-SCC. In the middle region, 60% were WD-SCC, 20% were MD-SCC, and 20% were PD-SCC. In the caudal region, 50% were WD-SCC, 27,8% were MD-SCC, and 22,2% were PD-SCC. Metastasis occurred in 57.75% of the cases, mostly to regional lymph nodes, and were observed in 58.82% of the cases with SCCs of the cranial region; in 40% of the middle region, and in 61.11% of the caudal region. Metastasis to regional lymph nodes and/or to distant organs were found in 44.44% of WDSCC, 75% of MD-SCC, and 100% of PD-SCC. Migration and invasion patterns were analyzed through the immunohistochemistry technique for cytokeratin. Islands and ribbons of neoplastic keratinocytes predominated in the WD-SCCs. The patterns varied greatly in the MD-SCCs, although small aggregates, ribbons, and cords predominated. PD-SCCS were characterized by small aggregates and individual cells. Lymphatic or hematogenous invasion were detected in 11/40 SCCs. There were SCCs originating from the ductal epithelium of the salivary glands. This finding was not previously reported. The intensity of the LPII was more accentuated in the BD-SCCs than in the MDs or PDs. The intensity of the desmoplastic reaction was quantified through the immunohistochemistry technique for vimentin, and was more severe in the PD-SCCs. The tumor-associated tissue eosinophilia (TATE) was measured in the SCCs and classified as mild, moderate, or severe. The only positive statistically significant association was established between TATE and LPII intensities. Cell proliferation was evaluated through quantification of the argyrophilic nucleolar organizer regions (AgNORs) on the neoplastic keratinocytes. AgNOR mean value and standard deviation (±sd) for WD-SCCs were 1.65 (±0.23), for MD-SCCs were 1.88 (±0.31), and for PD-SCCs were 2.39 (±0.26). The correlation between the AgNOR index and each histopathological grade was statistically significant. In conclusion, the factors which influenced the biological behavior of SCCs were the degree of cell differentiation, the patterns of migration and invasion, the intensity of LPII, TATE and desmoplastic reation, and the cell proliferation index measured through quantification of the AgNORs. |
