ABSTRACT
Objective:To comprehensively analyze the clinical values of serum tumor markers of colon cancer, including carbohydrate antigen 724 (CA724), cytokeratin 19 fragment antigen (CYFRA21-1), carbohydrate antigen199 (CA199) and carcinoembryonic antigen (CEA) in the diagnosis and prognosis prediction of colon cancer in patients.Methods:The clinical data of 160 patients with colon cancer who received treatment in Zhuji Central Hospital from January 2018 to December 2020 (observation group) and the clinical data of 156 patients with benign colon polyps who concurrently received physical examination (control group) were retrospectively analyzed. All patients underwent CA724, CYFRA21-1, CA199 and CEA tumor marker screening. The levels of tumor markers, the positive rate of a single tumor marker, and the positive rate of a combination of four markers were compared between the control and observation groups. The levels of tumor markers were compared among different pathological stages. The levels of serum tumor markers were compared among patients with different prognoses based on 1-year follow-up data.Results:CA199-positve rate, CEA-positive rate, CYFRA21-1-positve rate, CA724-positive rate, and the positive rate of a combination of four tumor markers were 85.63% (137/160), 86.88% (139/160), 71.88% (115/160), 85.00% (136/160), and 95.63%(153/160), respectively, which were significantly higher than those in the control group ( χ2 = 8.64, 10.28, 8.33, 9.93, 7.27, all P < 0.001). Serum CA199, CEA, CYFRA21-1 and CA724 levels in patients with stage III-IV colon cancer were (58.96 ± 13.59) U/mL, (38.69 ± 11.84) μg/L, (14.78 ± 3.68) μg/L, (23.68 ± 5.38) U/mL, respectively, which were significantly higher than those in patients with stage I-II colon cancer [(48.35 ± 9.03) U/mL, (23.96 ± 12.25) μg/L, (9.57 ± 2.53) μg/L, (13.02 ± 4.32) U/mL, t = 10.29, 12.02, 8.47, 10.54, all P < 0.001). One-year follow-up results showed that serum levels of CA199, CEA, CYFRA21-1, CA724 in patients with recurrence and metastasis of colon cancer were (38.68 ± 3.04) U/mL, (17.12 ± 4.96) μg/L, (8.94 ± 2.32) μg/L, (11.22 ± 1.94) U/mL, which were significantly higher than those in patients without recurrence of colon cancer [(30.02 ± 2.95) U/mL, (3.75 ± 1.06) μg/L, (3.06 ± 1.15) μg/L, (6.28 ± 1.53) U/mL, t = 8.73, 11.02, 7.72, 7.57, all P < 0.001]. Conclusion:Serum levels of CEA, CA199, CA724 and CYFRA21-1 can be used as important indicators for diagnosis and prognosis prediction of colon cancer.
ABSTRACT
The targeted population for HPV infection has peak infection at young adults, but studies point to the emergence of a new peak of viral infection and injuries later, probably by changesin sexual behaviour, waning immunity over time or reactivation of latent infection. Whereas the cervical squamous intraepithelial lesion high grade, mainly cervical intraepithelial neoplasia grades III (CIN III) have significant potential for progression to invasive carcinoma, the procedures of choice for the diagnosis and treatment in the target population are essential for the prevention of cervix cancer. Objective: To determine the prevalence of CIN II/III among patients seen in Cervical Pathology Clinic of Gynecology Department at the University Hospital Antonio Pedro from May 1996 to May 2013, relating toage in which this diagnosis was made. Method: It was selected patients referred to the Cervical Pathology Clinic for altered cytology and diagnosed through biopsy guided by colposcopy with CIN II / III. They were segmented into the following age groups: 15 to 24, 25 to 34, 35 to 44, 45 to 54, 55 to 64, 65 to 74, 75 to 84 and 85 to 94 years old. Results: Between 25 and 64 years of age, there were 36.5% of patients in these age groups with CIN II/III. However, it was found that 19% of patients younger than 25 years and 14.2% at 64 years also had such a diagnosis. Conclusion: The target population according to Brazilian Ministry of Health would let 16.2% of women with high-grade lesions withouta diagnosis, which corresponds to 11.3% of all high-grade cervical lesions.
A população alvo de infecções pelo HPV tem como pico adultos jovens, porém estudos apontam para um novo pico mais tardio, provavelmente por alterações do comportamento sexual, diminuição da imunidade ou reativação da infecção latente. Considerando que as lesões intraepiteliais escamosas de alto grau do colo uterino, sobretudo a neoplasia intraepitelial cervical grau III (NIC III) tem potencial significativo de progressão para carcinoma invasor,os procedimentos de escolha para diagnóstico e tratamento na população alvo são essenciais para a prevenção do câncer de colo uterino. Objetivo: Verificara prevalência de NIC II/III dentre as pacientes atendidas no Ambulatório de Patologia Cervical do Serviço de Ginecologia do Hospital Universitário Antônio Pedro no período de maio de 1996 a maio de 2013, relacionando com a faixa etária em que este diagnóstico foi realizado. Método: Selecionou-se as pacientes encaminhadas ao Ambulatório de Patologia Cervical por citologia oncótica alterada e diagnosticadas, por meio de biópsia dirigida pela colposcopia, comNIC II/III. Foram segmentadas nas seguintes faixas etárias: 15 a 24, 25 a 34, 35 a 44, 45 a 54, 55 a 64, 65 a 74, 75 a 84 e 85 a 94 anos. Resultados: Entre 25e 64 anos de idade, houve 36,5% de pacientes nestas faixas etárias com NIC II/III. Entretanto, verificou-se que 19% de pacientes com menos de 25 anos e14,2% com mais de 64 anos também apresentavam tal diagnóstico. Conclusão: A população-alvo preconizada pelo Ministério da Saúde deixaria 16,2% dasmulheres com lesões de alto grau à margem de um diagnóstico, o que corresponde a 11,3% de todas as lesões de alto grau do colo uterino.

There were 14 cases of malignant tumor, amongwhich,there were two cases of non Hodgkin′s lymphoma and two of leiosarcoma,one angiosarcoma and metastatic splenic malignant tumor in 9 cases.[WT5”HZ]Conclusion [WT5”BZ]Therapeutics should be adopted according the nature of splenic diseases, based on clinical and image characteristics.
