The burden of chronic ureteral stenting in cervical cancer survivors

ABSTRACT Purpose Ureteral obstruction in cervical cancer occurs in up to 11% of patients, many of whom undergo ureteral stenting. Our aim was to describe the patient burden of chronic ureteral stenting in a population-based cohort by detailing two objectives: (1) the frequency of repeat procedures for ureteral obstruction; and, (2) the frequency of urinary adverse effects (UAEs) (e.g., lower urinary tract symptoms, flank pain). Materials and Methods From SEER-Medicare, we identified 202 women who underwent ureteral stent placement prior to or following cervical cancer treatment. The frequency of repeat procedures and rate ratios were compared between treatment modalities. The rates and rate ratios of UAEs were compared between our primary cohort (stent + cervical cancer) and the following groups: no stent + cervical cancer, stent + no cancer, and no stent + no cancer. The “no cancer” group was drawn from the 5% Medicare sample. Results 117/202 women (58%) underwent >1 stent procedure. The frequency of additional procedures was significantly higher in patients who received radiation as part of their treatment. UAEs were very common in women with stent + cancer. The rate of UTI was 190 (per 100 person-years), 67 for LUTS, 42 for stones, and 6 for flank pain. These rates were 3-10 fold higher than in the no stent + no cancer control group; rates were also higher than in the no stent + cancer and the stent + no cancer women. Conclusions The burden of disease associated with ureteral stents is higher than expected and urologists should be actively involved in stent management, screening for associated symptoms and offering definitive reconstruction when appropriate.

Cervical cancer: Renal complications and survival after percutaneous nephrostomy / Câncer de colo uterino: complicações renais e sobrevida após nefrostomia percutânea

SUMMARY Introduction: Obstructive nephropathy is a frequent complication in the course of advanced cervical cancer (CC), and ultrasonography-guided percutaneous nephrostomy (PCN) is a well established technique for fast ureteral desobstruction. Objective: To identify possible factors related to the survival and quality of life of patients with advanced CC presenting acute urinary obstructive complications that after desobstruction by PCN recovered urinary flux and renal function. Method: This is an analytical, descriptive, cross-sectional study that included 45 patients with CC who underwent PCN and were divided into 2 groups: “death” (DG) and “survival” (SG), in a public hospital that is reference for oncologic diseases in Northern Brazil. Results: The mean serum creatinine of the patients preceding PCN was >10 mg/dL, and after PCN <2 mg/dL. The cutoffs of 8.7 g/dL for Hb (p=0.0241) and 27% for Ht (p=0.0065) indicated the values that better discriminate the outcomes of the groups. The presence of low blood pressure was statistically correlated (p=0.0037) to the outcome “death”. Changes in glomerular filtration rate (already reduced in all cases) were not associated to the levels of Hb/Ht or to the outcome “death” during the nephrological follow-up. Conclusion: PCN was responsible for the recovery of renal function in 61.7% of the patients, leading to interruption of renal replacement therapy (RRT) in all of those patients. Hb levels >8.7g/dL and Ht >27% were associated to longer survival, and the presence of low blood pressure during follow-up was associated with progression to death.

RESUMO Introdução: a nefropatia obstrutiva é complicação frequente na evolução do câncer do colo uterino (CCU) avançado e a nefrostomia percutânea guiada por ultrassonografia (NFT) é uma técnica bem estabelecida para a rápida desobstrução ureteral. Objetivo: esclarecer os fatores relacionados à evolução ou não para óbito e qualidade de vida das pacientes com CCU avançado com complicações obstrutivas urinárias agudas e que, após desobstrução pela NFT, recuperaram fluxo urinário e função renal. Método: foi realizado estudo transversal analítico descritivo, que avaliou dois grupos de pacientes com CCU submetidas à NFT [óbito (GO) e sobrevida (GS)], em um hospital público, referência para doenças oncológicas da região Norte do país. Resultados: a creatinina sérica média inicial era >10 mg/dL pré-NFT e tornou-se <2 mg/dL após. Quanto à sobrevida, os pontos de corte de 8,7 g/dL de Hb e 27% de Ht melhor discriminaram a evolução dos grupos GO e GS (p=0,0241 e p=0,0065). Hipotensão se associou significantemente (p=0,0037) com a evolução para óbito. Variações na taxa de filtração glomerular, que já era reduzida em todos os casos, não se associaram aos níveis de Hb/Ht ou à evolução para óbito durante seguimento nefrológico. Conclusão: a NFT permitiu a recuperação da função renal em 61,7% das pacientes com CCU, dispensando terapia de substituição renal. Níveis de Hb >8,7 g/dL e Ht >27% estiveram associados a maior sobrevida, e a hipotensão durante o seguimento associou-se com evolução para óbito.

High-risk human papillomavirus and cervical lesions among women living with HIV/AIDS in Brazilian Amazon, Brazil

ABSTRACT OBJECTIVE: The goal of this study was to determine the prevalence of human papillomavirus infection infection and cervical lesions and its associated factors among HIV infected women attending an AIDS clinic in Amazonas state, Brazil. METHODS: Cross-sectional study. Women attending an AIDS clinic in the city of Manaus between March and December 2011 for gynecological examination were invited to participate. Enrolled patients answered a standardized interview including demographical, behavioral, and clinical data. Additionally, patients underwent a gynecological evaluation with collection of cervical samples for cytological analysis and high-risk human papillomavirus infection hybrid capture. A blood sample was also obtained to determine CD4 and viral load levels. RESULTS: A total of 310 (82.9%) women participated in the study. High-risk human papillomavirus infection was detected in 191 (61.6%) cases; 24 (13.5%) had low-grade squamous intraepithelial lesion (SIL) and 4 (2.2%) high-grade SIL. No invasive cervical cancer was diagnosed. Median age was 32 (interquartile range (IQR): 27-38) years and median of education was 8.5 (IQR 4-11) years of schooling and 56.1% had a monthly income up to US$180. In multivariate analysis, being less than 30 years old [OR = 1.7 (95% CI: 1.2-2.4,p = 0.005)], high-grade SIL [OR = 6.5 (95% CI: 1.6-23.0, p = 0.009)], and CD4 counts <200 cells/mm3 [OR = 1.6 (95% CI: 1.2-2.0, p < 0.001)] were associated with high risk human papillomavirus infection infection. CONCLUSIONS: In the present study high-risk human papillomavirus infection was frequent and it was associated to high-SIL. These results show the importance of gynecologic examinations in routine care and follow-up required by those who present with cervical lesions.

Objetivo - Avaliar a prevalência de câncer de colo do útero e infecções genitais em mulheres atendidas no serviço de saúde pública de Goiânia-GO. O exame de Papanicolaou é o método utilizado para detecção das lesões intraepiteliais e neoplásicas da cérvice uterina, tendo importante papel na prevenção do câncer do colo do útero e no diagnóstico das infecções genitais. Métodos - Estudo retrospectivo dos laudos dos exames citopatológicos das mulheres atendidas nas Unidades de Atenção Básica em Saúde (UABS) de Goiânia-GO, entre 03/2006 a 05/2008. Os esfregaços citológicos foram analisados no Centro de Análises Clínicas Rômulo Rocha da Faculdade de Farmácia da Universidade Federal de Goiás (CACRR/FF/UFG). Resultados - Um total de 15.615 mulheres foi incluído no estudo. A mediana de idade foi de 33 anos (14-93 anos), a maioria (57,6%) tinha entre 20 e 39 anos e 6,6% (n=1.034) eram < 20 anos de idade. Mais de 50% dos casos de infecção entre adultas e adolescentes eram causados por Gardnerella vaginalis e 13,6% por Trichomonas vaginalis. Entre mulheres mais jovens (20-39 anos),16,9% das infecções foi causada por Candida sp. Aproximadamente 7,6% dos esfregaços avaliados apresentaram alterações celulares, sendo 4,9% células escamosas atípicas de significado indeterminado/lesão intraepitelial escamosa de baixo grau (ASC-US/LSIL) para as mulheres entre 20-29 anos e 2,6% células escamosas atípicas com possível lesão de alto grau/lesão intraepitelial escamosa de alto grau e células glandulares atípicas (ASC-H/+) para mulheres entre 20 e 49 anos. Conclusão - Lesões graves em mulheres jovens chamam atenção para a necessidade de políticas de saúde pública que reforcem a importância do Papanicolaou para a prevenção do colo de útero.

Objective - To correlate the prevalence of cervical cancer and genital infections with the age of women treated at public health service of Goiânia-GO. Papanicolaou test is the method used for detection of intraepithelial and neoplastic lesions in the uterine cervix, playing an important role in cervical cancer prevention and helping in female genital infections'diagnosis. Methods - Women's cytopathological tests were analyzed at Health Care Units from Goiânia-GO, between 03/2006 and 05/2008. Smears were analyzed at Clinical Analysis Laboratory Rômulo Rocha, at Pharmacy Faculty of the Federal University of Goiás. Results - The total of 15.615 women were included in this study. The median age was 33 years (14-93 years), 57.6% were between 20 and 39 years of age and 6.6% were adolescents <20 years of age. More than 50% of cases of infection among adults and adolescents were caused by Gardnerella vaginalis, followed by 13.6% by Trichomonas vaginalis and to 16.9% by Candida sp. Approximately, 7.6% of smears evaluated showed cellular alterations, and 4.9% atypical squamous cells of undetermined significance/squamous intraepithelial lesion of low grade (ASC-US/LSIL) for women aged 20-29 years and 2.6% atypical squamous cells can damage high-grade/squamous intraepithelial lesion high-grade and atypical glandular cells (ASC-H/+) for women aged 20-49 years. Conclusion - Serious injuries in young women draw attention to the need for public health policies that reinforce the importance of the Papanicolaou test for cervical cancer prevention.

Factores de riesgo de cáncer cervicouterino invasor en mujeres mexicanas / Risk factors in invasive cervical cancer among Mexican women

OBJETIVOS: Evaluar la asociación entre cáncer cervicouterino (CaCu) invasor y el virus del papiloma humano de alto riesgo (VPH-AR) (carga viral/tipo 16), así como con factores ginecológicos y socioeconómicos. MATERIAL Y MÉTODOS: Estudio de casos y controles pareado individualmente (215 casos con CaCu invasor y 420 controles). La población de estudio se reclutó entre los años 2000 y 2001. Se evaluaron variables tradicionalmente asociadas con CaCu (ginecológicas y socioeconómicas) y dos variables asociadas con la presencia de VPH (carga viral y el tipo 16). La presencia de VPH-AR se determinó mediante Captura de Híbridos II. La carga viral se midió a través de unidades relativas de luz y picogramos por ml (1 RLU=1 pg/ml), divididas en cuatro categorías: negativa (<1 pg/ml), baja carga viral (1-49 pg/ml), carga viral intermedia (50-499 pg/ml) y alta carga viral (>499 pg/ml). El análisis estimó razones de momios (RM) ajustadas a través de modelos de regresión logística condicionada. RESULTADOS: La presencia de VPH-AR incrementa en 78 veces la probabilidad de presentar CaCu invasor; cuando el VPH es tipo 16, el incremento es mayor (RM= 429.7) comparado con otros tipos (RM=64.1). Se observó una tendencia importante en la RM al elevarse la carga viral (RM=46.6 carga baja; RM=250.7 intermedia y RM=612.9 alta). Finalmente, los factores demográficos y obstétricos conocidos, incrementaron la probabilidad de CaCu invasor. No se observó asociación entre CaCu invasor y tabaquismo en la población de estudio. CONCLUSIONES: Este estudio contribuye a la identificación de las mujeres con alto riesgo de desarrollar CaCu invasor, entre las pacientes infectadas con VPH-AR. Por otra parte, confirma la importancia de la infección de VPH-AR y refleja la carga viral del VPH-AR como cofactor y posible promotor en el desarrollo de la enfermedad. Por último, este biomarcador puede contribuir a mejorar la prevención y la detección temprana de esta enfermedad.
