SUMMARY OBJECTIVES: The aim of this study was to evaluate CD56 immunostaining in the stroma of benign and malignant ovarian epithelial neoplasms and associate the CD56 immunostaining with prognostic factors and survival in ovarian cancer. METHODS: Patients with ovarian epithelial neoplasia (n=77) were studied with a prospective cohort. The CD56 immunostaining was evaluated in the peritumoral stroma. Two groups were evaluated: benign ovarian neoplasms (n=40) and malignant ovarian neoplasms (n=37). Data were recorded for histological type and grade, International Federation of Gynecology and Obstetrics staging, molecular subtype, and lymph node metastases. Fisher’s exact test and Kaplan-Meier survival curves were used, with a significance level of ≤0.05. RESULTS: We found greater CD56 stromal immunostaining in malignant neoplasms when compared to the group of benign neoplasms (p=0.00001). There was no significant difference in relation to the prognostic factors and survival. CONCLUSION: Malignant ovarian neoplasms showed higher stromal CD56 immunostaining. As the prognostic value of natural killer in ovarian cancer is controversial, knowing the specific function of each cell present both in the tumor tissue and systemically may help guide successful immunotherapies in the near future.

SUMMARY OBJECTIVE: The aims were to compare the red blood cells, platelet count, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, red cell distribution width, and fasting glucose in peripheral blood of patients with benign and malignant uterine neoplasms and to relate these laboratory parameters with prognostic factors and overall survival in cancer. METHODS: The results of the laboratory parameters were analyzed using the Mann-Whitney U test. Receiver operating characteristic curves were used to find the cutoff values. Overall survival was estimated using the Kaplan-Meyer method. RESULTS: Higher values of neutrophil-lymphocyte ratio and fasting glucose were found in cancer patients. Higher platelet-lymphocyte ratio values were associated with other subtypes when compared with endometrioid subtype; higher values of red cell distribution width were found in stage II/IV when compared with stage I; lower hemoglobin values were related to stage II/IV and nonendometrioid histological type. Platelet-lymphocyte ratio <145.56 was associated with longer overall survival. CONCLUSION: Hemoglobin and platelet-lymphocyte ratio values are prognostic factors in uterine corpus cancer.

RESUMO OBJETIVO Relacionar a sobrevida livre de doença e sobrevida global com câncer de ovário tipos I e II, assim como com parâmetros laboratoriais pré-operatórios biomarcadores. MÉTODOS Estudo retrospectivo realizado com base na coleta de dados de prontuários de pacientes com tumor ovariano. As curvas de Kaplan-Mayer foram realizadas em relação à análise estatística dos dados, sendo comparadas pelo teste de Log-rank. RESULTADOS A sobrevida livre de doença nas pacientes com câncer de ovário tipo I foi significativamente maior do que nas pacientes com câncer de ovário tipo II (p = 0,0013), bem como maior naquelas com níveis normais de CA-125 (p = 0,0243) e com relação plaquetas-linfócitos (RPL) inferior a 200 (p = 0,0038). A sobrevida global de pacientes com câncer de ovário tipo I foi significativamente maior do que em pacientes com tipo II, maior em pacientes com níveis séricos normais de CA-125 (p = 0,0039) e naquelas com glicemia de jejum pré-operatória menor que 100 mg / dL. CONCLUSÃO Os níveis de CA-125 podem predizer uma sobrevida global e livre de doença. A RPL < 200 pode sugerir uma maior sobrevida livre de doença, enquanto uma glicemia normal de jejum, uma maior sobrevida global.

SUMMARY OBJECTIVE To relate disease-free survival and overall survival with type I and type II ovarian cancer and preoperative laboratory parameters biomarkers. METHODS A retrospective study was carried out based on the collection of data from medical records of patients with ovarian tumors. Kaplan-Mayer curves were drawn based on the statistical analysis of the data and were compared using the Log-rank test. RESULTS Disease-free survival in type I ovarian cancer was significantly higher than in type II (p=0.0013), as well as in those with normal levels of CA-125 (p=0.0243) and with a platelet-lymphocyte ratio (PLR) lower than 200 (p=0.0038). The overall survival of patients with type I ovarian cancer was significantly higher than in patients with type II, as well as in patients with normal CA-125 serum levels (p=0.0039) and those with a preoperative fasting glucose of less than 100 mg/dL. CONCLUSION CA-125 levels may predict greater overall and disease-free survival. PLR < 200 may suggest greater disease-free survival, whereas normal fasting glucose may suggest greater overall survival.

Resumo O câncer de ovário é a principal causa de morte entre os tumores ginecológicos, já que na maioria dos casos (75%) o diagnóstico ocorre em estádios avançados. Métodos de rastreamento não estão disponíveis, já que a doença é rara, e osmétodos diagnósticos, como ultrassonografia e CA 125, não são capazes de reduzir a taxa de mortalidade desse câncer. Este artigo discute os principais fatores de risco para o câncer de ovário e as possíveis estratégias clínicas e cirúrgicas para a prevenção dessa doença.

Abstract Ovarian cancer is the leading cause of death among gynecologic tumors because in most of the cases (75%), the disease is diagnosed in advanced stages. Screening methods are not available since the disease is rare, and the tested methods, such as ultrasound and CA125, were not able to decrease the mortality rate for this type of cancer. This article discusses the main risk factors for ovarian cancer, and the potential clinical and surgical strategies for the prevention of this disease.

Os objetivos deste estudo foram avaliar o desempenho do PCR para detecção de HPV 16/18 versus PCR sonda única para a detecção de HPV de alto risco, avaliar estes métodos na detecção de neoplasia intraepitelial cervical (NIC) no seguimento de ASCUS, e comparar os custos de citologia, métodos de PCR, colposcopia e biópsia no Sistema Único de Saúde. Das 81 pacientes com ASCUS, 41 (50,6%) foram positivas para o HPV 16/18 PCR, e 47 (58,02%) foram positivas para PCR sonda única para HPV de alto risco. O valor preditivo negativo foi de 93,75% para HPV 16/18 PCR e 100% para PCR sonda única em casos que evoluíram para NIC de alto grau. Os custos anuais encaminhando todas as pacientes com ASCUS para a colposcopia, encaminhando à colposcopia as pacientes com ASCUS e PCR positivo para HPV 16/18 e encaminhando à colposcopia aquelas pacientes com ASCUS e PCR sonda única para HPV de alto risco positivo foram de R$2.144,52, R$6.307,44 e R$3.691,80, respectivamente. Considerando eventual redução dos custos para utilização em grandes quantidades, este método poderia ser realizado em ASCUS.

This study aimed to assess the performance of PCR as a means of detecting HPV 16/18 compared to the single probe-based PCR for detecting high-risk HPV, and evaluate these methods for detecting cervical intraepithelial neoplasia (CIN) in follow-ups for ASCUS testing. It also compares the costs of cytology, PCR methods, colposcopy and biopsy in the Brazilian Unified National Health System. Of the 81 patients with ASCUS, 41 (50.6%) tested positive for HPV 16/18 in PCR testing and 47 (58.02%) tested positive for high-risk HPV with single probe-based PCR testing. The negative predictive value was 93.75% for HPV 16/18 PCR and 100% for single probe-based PCR in cases that progressed to high-grade CIN. The annual costs of patient referral were the following: R$2,144.52 for referral of patients with ASCUS cytology for colposcopy; R$6,307.44 for referral of patients with ASCUS cytology and PCR positive for HPV 16/18 or colposcopy; R$3,691.80 for referral of patients with ASCUS cytology with single probe-based PCR positive for high-risk HPV. Therefore, cost per user can be reduced by performing single probe-based PCR for high-risk HPV on patients with ASCUS.

CONTEXTO E OBJETIVO: Muitos fatores influenciam a ocorrência de vulvovaginites. Os objetivos foram avaliar diferenças relacionadas à cor da pele e idade na flora vaginal e vulvovaginites. TIPO DE ESTUDO E LOCAL: Estudo transversal; hospital de referência terciário (Universidade Federal do Triângulo Mineiro, Uberaba). MÉTODOS: Mulheres saudáveis em atendimento de rotina para exames ginecológicos foram divididas em brancas (n = 13.881) e não brancas (n = 5.295) e avaliadas quanto a vulvovaginites e flora vaginal. Para análise estatística, foram utilizados teste X², regressão logística e odds ratio. RESULTADOS: Microflora vaginal foi dependente da cor da pele, com maior ocorrência de "clue cells", Trichomonas vaginalis e bacilos cocoides em não brancas (p < 0,0001); bacilos de Döderlein e flora citolítica foram mais prevalentes em brancas (p < 0,0001 e p < 0,05, respectivamente). Flora vaginal foi dependente da idade nos grupos de cor da pele. Entre não brancas, "clue cells", Trichomonas e bacilos cocoides foram mais prevalentes nas idades: 21 a 50 anos, até 40 anos, e 21 a 40 anos respectivamente (p < 0,05). Durante as fases proliferativa e secretória, mulheres não brancas tiveram maior probabilidade de apresentar "clue cells", Trichomonas, Candida e cocoides (odds ratio, OR - fase proliferativa: 1,31; 1,79; 1,6 e 1,25 respectivamente; fase secretória: 1,31; 2,88; 1,74 e 1,21 respectivamente), e menor chance de apresentarem flora Döderlein (OR - fase proliferativa: 0,76; fase secretória: 0,66) comparadas com brancas, independentemente da idade. CONCLUSÕES: Há diferenças na ocorrência de vulvovaginites relacionadas com a cor da pele, podendo haver associação com variações na flora vaginal.

CONTEXT AND Objective: Many factors influence occurrences of vulvovaginitis. The aims here were to assess skin color and age-related differences in the vaginal flora and occurrences of vulvovaginitis. DESIGN AND SETTING: Cross-sectional study; tertiary referral hospital (Universidade Federal do Triângulo Mineiro, Uberaba). METHODS: Healthy women who underwent routine outpatient gynecological assessments were assessed for vulvovaginitis and vaginal flora and then divided into whites (n = 13,881) and nonwhites (n = 5,295). Statistical analysis was performed using the X² test, logistic regression and odds ratios. RESULTS: The vaginal microflora was skin-color dependent, with greater occurrence of clue cells, Trichomonas vaginalis and coccobacilli in nonwhite women (p < 0.0001). Döderlein bacilli and cytolytic flora were more prevalent in white women (p < 0.0001 and p < 0.05, respectively). The vaginal microflora was age-dependent within the skin color groups. Among the nonwhite women, clue cells were more prevalent in women aged 21 to 50 years; Trichomonas in women up to 40 years and coccobacili in women between 21 and 40 years (P < 0.05). During the proliferative and secretory phases, the nonwhite women were more likely to present clue cells, Trichomonas, Candida and coccobacilli (OR, proliferative phase: 1.31, 1.79, 1.6 and 1.25 respectively; secretory phase: 1.31, 2.88, 1.74 and 1.21 respectively), while less likely to present Döderlein flora (OR, proliferative phase: 0.76; secretory phase: 0.66), compared with white women, irrespective of age. CONCLUSIONS: There are differences in vulvovaginitis occurrence relating to skin color, which may be associated with variations in vaginal flora.

O trabalho objetivou avaliar o desempenho e o custo do PCR e captura híbrida na detecção de neoplasia intra-epitelial cervical (NIC) em pacientes com anormalidades citológicas (ASCUS/lesões de baixo grau - LBG), e a viabilidade da implantação destes métodos no serviço público de saúde. Observou-se valor preditivo negativo de 92,86% e eficiência de 87,8% da colposcopia para diagnóstico de NIC. A sensibilidade do PCR e captura híbrida na detecção de NIC foi de 83,33% e 66,67%, respectivamente. O valor preditivo negativo no diagnóstico de NICII e III do PCR e captura híbrida foi de 100% e 94,74%, respectivamente. O custo anual das oitenta pacientes foi menor encaminhando-se todas as pacientes com ASCUS/ LBG à colposcopia do que se fossem realizados testes biomoleculares e encaminhando-se aquelas com resultados positivos à colposcopia. Portanto, por enquanto, é inviável financeiramente para o Sistema Único de Saúde a implantação de métodos de biologia molecular para pacientes com ASCUS e LBG à citologia cérvico-vaginal, mas considerando que o uso em grande escala poderia torná-los mais baratos, o PCR deveria ser o método escolhido, por ter menor custo, alto valor preditivo negativo e melhor sensibilidade.

This study aimed to evaluate the performance and cost of using polymerase chain reaction (PCR) and hybrid capture in the detection of cervical intraepithelial neoplasia (CIN) in patients with cytological abnormalities (ASCUS/low-grade squamous intraepithelial lesion - LSIL), and the feasibility of implementing these methods in Brazil's Unified National Health System (SUS). Colposcopy gave a negative predictive value of 92.86% and efficiency of 87.8% for diagnosing CIN. The sensitivity of PCR and hybrid capture for detecting CIN was 83.33% and 66.67%, respectively, and the negative predictive value for diagnosing CIN2/CIN3 was 100% and 94.74%, respectively. The annual cost for 80 patients was lower when all patients with ASCUS/LSIL were referred for colposcopy than when HPV testing was performed and those with positive results were referred for colposcopy. Therefore, at present, it is financially unfeasible for the National Health System to implement HPV testing to screen patients with cytological abnormalities (ASCUS/LSIL). However, considering that large-scale use might make such methods cheaper, PCR should be the chosen method, since it is less expensive, more sensitive, and has a high negative predictive value.
