RESUMEN
SUMMARY OBJECTIVE: This study was designed to investigate the link between survival and prognostic factors such as tumor size, lymph node metastasis, and metabolic activity detected on positron emission tomography/computed tomography in patients with limited-stage small cell lung carcinoma. METHODS: Patients who were admitted to our hospital with pathological diagnosis of limited-stage small cell lung cancer between January 2015 and December 2019 and were older than 18 years were retrospectively screened. RESULTS: A total of 77 patients, including 10 females and 67 males, were included in the study. While there were 39 patients over 60 years of age, 38 patients were under 60. The ratios of male patients, N stage, multiple lymph nodes, distant metastasis, brain metastasis, and prophylactic cranial irradiation in the deceased patients' group were significantly (p=0.008, p=0.000, p=0.000, p=0.000, p=0.013, p=0.000, respectively) higher than those in the living patients' group. In the univariate model, we observed that gender, smoking, T stage, N stage, multiple lymph nodes, distant metastasis, brain metastasis, liver metastasis, sequential chemotherapy, sequential radiotherapy, concurrent chemoradiotherapy, and prophylactic cranial irradiation had significant effect (p=0.049, p=0.021, p=0.022, p=0.000, p=0.000, p=0.000 p=0.003, p=0.037, p=0.029, p=0.049, p=0.000, respectively) on survival time. In the multivariate model, smoking, N stage, liver metastasis, and prophylactic cranial irradiation demonstrated significant independent effect (p=0.010, p=0.003, p=0.004, p=0.000, respectively) on survival time. CONCLUSION: Our findings provide useful information for better patient management, especially in terms of negative factors on the continuation of survival during and after the treatment of limited-stage small cell lung carcinoma patients.
RESUMEN
SUMMARY OBJECTIVE: The effects of Certolizumab, a pegylated monoclonal antibody to tumor necrosis factor α, on experimentally induced acute pancreatitis (AP) were examined. METHODS: Thirty-six Wistar Albino male rats were randomly divided into four groups. Group I was the control group and no medication administered to this group. Group II was the Certolizumab group, and 100 ml/kg serum physiologic administered into the biliopancreatic duct and a single dose of 10 μg Certolizumab was simultaneously administered intraperitoneally. Acute pancreatitis was induced with a retrograde injection of 3% Na taurocholate into the common biliopancreatic duct in the study (Group III) and treatment (Groups IV) groups. Rats were sacrificed 72 hours later. Serum amylase, lipase, lactate dehydrogenase activities, along with pancreatic histopathology, were examined. RESULTS: Certolizumab treatment significantly decreased serum amylase, lipase, and LDH levels; histopathologically edema, hemorrhage, parenchymal necrosis, fat necrosis, and infiltration scores; immunohistochemically MDA, MPO, TNF-α and Caspase-3 activity. CONCLUSION: The results support the idea that certolizumab might be beneficial for the severity of AP.
RESUMO OBJETIVO: Os efeitos de Certolizumab, um anticorpo monoclonal pegilado para o fator de necrose tumoral α, na pancreatite aguda induzida experimentalmente (PA) foram examinados. MÉTODO: Trinta e seis ratos Wistar Albino foram divididos aleatoriamente em quatro grupos. O Grupo I foi considerado o grupo controle e não recebeu medicação; o Grupo II foi o grupo Certolizumab e recebeu 100 ml/kg de soro fisiológico administrado no ducto biliopancreático e dose única de 10 mg Certolizumab administrada por via intraperitoneal simultaneamente. A pancreatite aguda foi induzida com uma injeção retrógrada de uma solução de 3% taurocolato de sódio aplicada no ducto biliopancreático comum nos grupos de estudo (Grupo III) e tratamento (Grupos IV). Os ratos foram sacrificados 72 horas depois. As atividades séricas de amilase, lipase, lactato desidrogenase, juntamente com a histopatologia pancreática, foram examinadas. RESULTADOS: O tratamento com Certolizumab diminuiu significativamente os níveis séricos de amilase, lipase e LDH; edema histopatológico, hemorragia, necrose paranquimatosa, necrose gordurosa e escores de infiltração; atividade imuno-histoquímica de MDA, MPO, TNF-α e Caspase-3. CONCLUSÃO: Estes resultados suportam a ideia de que o Certolizumab pode ser benéfico para a gravidade da PA.
