The data suggest that SLN-mapping identifies more pelvic node metastases than lymph node dissection alone and increases the node detection rate by 12.5% after IHC. Furthermore, no isolated para-aortic node metastases are observed when SLN is detected.

Chylous ascites should be included in differential diagnosis of abdominal distention after surgical retroperitoneal approach or radiotherapy. Most of the patients may have their chylous ascites successfully treated with conservative management. However, the best policy is to prevent chylous complications by employing meticulous dissection techniques and careful control of the major lymphatics by suture ligation during the primary surgical intervention.

This study demonstrated for the first time that RKIP expression is lost during the carcinogenic evolution of endometrial tumours and that the loss of RKIP expression is associated with a malignant phenotype. Functional studies are needed to address the biological role of RKIP downregulation in endometrial cancer.

Embryonal rhabdomyosarcoma (RMS) of the female genital tract usually occurs in the vagina during childhood. The uterine cervix as a primary site is rare, but is more frequent until the second decade of life. It usually has a good prognosis and the treatment is based on multidrug chemotherapy, radiotherapy and surgery. RMS accounts for <5% of all adult soft tissue sarcomas. Previous reports that included all primary sites showed a poorer five-year disease specific survival for adults with RMS when compared to the pediatric population. This difference has been attributed to a higher proportion of adverse prognostic clinical and pathological factors, and to inadequate treatment given to adults with RMS. A total of 115 patients with cervical embryonal RMS have previously been described; however, only 10 cases were reported in women older than 40 years. We present a 47-year-old woman treated with radical hysterectomy followed by adjuvant chemotherapy and review the current literature.

We hypothesized that the activation of cyclooxygenase (COX)-2, epidermal growth factor receptor (EGFR), and ErbB-2 signaling is required for cervical intraepithelial neoplasia (CIN) lesions to progress to cervical cancer. A retrospective analysis was performed in 179 patients with Stage I squamous cell carcinoma (SCC) and 233 patients with CIN (112 CIN I, 47 CIN II, and 74 CIN III). COX-2, EGFR, and ErbB-2 expression was analyzed by immunohistochemistry using the ACIS III automated imaging system. The mean expression of COX-2, EGFR, and ErbB-2 was compared between the various stages of CIN and SCC. COX-2 mean expression was predominantly cytoplasmic, increasing significantly from CIN I to CIN II, CIN III, and SCC (P<0.001). EGFR mean expression also rose significantly during tumor progression from CIN I to SCC (P=0.001). CIN I samples were negative for ErbB-2 expression. CIN II, CIN III, and SCC were considered positive for ErbB-2 expression in 2.2%, 14%, and 16.2% of cases, respectively. There was also a statistically significant correlation between increase of ErbB-2 positivity from CIN to SCC. We conclude that COX-2, EGFR, and ErbB-2 expression increase significantly during the progression of CIN to cancer.
