Accuracy of detection rate and intraoperative sentinel lymph node assessment in early-stage cervical carcinoma

Objective: This study was aimed at evaluating the usefulness of paired box-2 gene (PAX-2) in the diagnosis of renal tumors. Materials and Methods: This study included 60 renal tumors. The newly prepared hematoxylin and eosin stained slides of all cases were evaluated and the diagnoses were confirmed or revised for each tumor according to the 2004 World Health Organization classification of renal tumors. Representative and consecutive sections of each tumor were submitted for anti-PAX-2 antibody immunohistochemistry. The pattern of staining (nuclear or cytoplasmic) was also noted. PAX-2 expression in tumors was correlated with low- and high-nuclear grades (Fuhrman nuclear grades). Results: The 45/60 (75%) cases showed PAX-2 nuclear immunoexpression. The frequency of positivity in renal tumors was seen in 29/34 (85.5%) and 12/15 (80%) cases of clear cell RC, papillary RCC, respectively. The PAX-2 was positive in 20/45 cases for score 1+. The 16/45 cases were categorized into score 2+, and 9/45 cases were categorized into score 3+. Conclusion: PAX-2 is a diagnostically useful marker for primary renal tumors and is inversely proportion to the grades of the renal tumor.

Prognostic factors associated with local recurrence in squamous cell carcinoma of the vulva / 부인종양

OBJECTIVE: To analyze the prognostic factors related to the recurrence rate of vulvar cancer. METHODS: Retrospective study of 87 patients diagnosed of vulvar squamous cell carcinoma diagnosed at a tertiary hospital in Madrid between January 2000 and December 2010. RESULTS: The pathological mean tumor size was 35.1+/-22.8 mm, with stromal invasion of 7.7+/-6.6 mm. The mean free margin after surgery was 16.8+/-10.5 mm. Among all patients, 31 (35.6%) presented local recurrence (mean time 10 months; range, 1 to 114 months) and 7 (8%) had distant metastases (mean time, 5 months; range, 1 to 114 months). We found significant differences in the mean tumor size between patients who presented a relapse and those who did not (37.6+/-21.3 mm vs. 28.9+/-12.1 mm; p=0.05). Patients with free margins equal or less than 8 mm presented a relapse rate of 52.6% vs. 43.5% of those with free margin greater than 8 mm (p=0.50). However, with a cut-off of 15 mm, we observed a local recurrence rate of 55.6% vs. 34.5%, respectively (p=0.09). When the stromal invasion cut-off was >4 mm, local recurrence rate increased up to 52.9% compared to 37.5% when the stromal invasion was 4 mm, high risk predictors of local recurrence rate.

Complicaciones obstétricas tras una traquelectomía radical: caso clinico y revisión de la literatura / Obstetric complications after a radical trachelectomy: case report and review of literature

Introducción: la traquelectomía radical (TR) es una técnica quirúrgica utilizada en estadios precoces del cáncer de cérvix en aquellas mujeres que desean conservar la capacidad reproductiva. Los embarazos posteriores a esta técnica quirúrgica pueden desencadenar complicaciones obstétricas. El presente artículo tiene como objetivo hacer una revisión de la literatura en relación al pronóstico obstétrico de estas pacientes. Metodología: en este estudio se presenta un caso clínico. Posteriormente, se realiza una búsqueda en las bases de datos MEDLInE, vía PubMed, y Cochrane con las palabras clave “cáncer de cérvix”, “traquelectomía radical”, “embarazo” y “complicaciones obstétricas”. Resultados: se evaluó un total de 17 artículos que comprendieron revisiones, artículos de opinión y casos clínicos. Conclusión: la preservación de la fertilidad en estadios precoces del cáncer de cérvix mediante la traquelectomía radical está adquiriendo cada vez mayor aceptación a medida que se publican más casos en la literatura. Los resultados obstétricos parecen ser cada vez más favorables aunque son más numerosas las complicaciones en comparación con la población general.

Introduction: radical trachelectomy (TR) is a surgical technique which is used in the early stages of cervical cancer in females wishing to conserve their reproductive ability. Pregnancies following this surgical technique having been applied could trigger obstetric complications. This article was thus aimed at reviewing the literature related to these patients’ obstetric prognosis. Methodology: a clinical case is presented. A literature search was made in MEDLInE databases, via PubMed and Cochrane, using the following key words: “cervical cancer”, “radical trachelectomy”, “pregnancy”, “obstetric complications”. Results: 17 articles were evaluated, covering review articles, articles expressing opinion and clinical cases. Conclusion: preserving fertility in early stages of cervical cancer by radical trachelectomy is increasingly acquiring more acceptance as more cases are published in the literature. Obstetric results seem to be becoming more favorable even though complications are becoming more numerous compared to incidence in the general population.
