The Groningen International Study on Sentinel nodes in Vulvar cancer (GROINSS-V)-II investigated whether inguinofemoral radiotherapy is a safe alternative to lymphadenectomy (IFL) vulvar patients with metastatic sentinel node (SN).GROINSS-V-II was prospective multicenter phase-II single-arm treatment trial, including early-stage (diameter < 4 cm) without signs of lymph involvement at imaging, who had primary surgical (local excision SN biopsy). Where the involved (metastasis any size), given...

As the few randomized controlled trials available in literature comparing botulinum toxin (BT) injection with established endoscopic treatment of achalasia cardia, i.e. pneumatic dilatation, showed conflicting results, we conducted a prospective trial. Seventeen consecutive patients cardia diagnosed during period between December 1997 and February 2000 were into two groups [pneumatic dilatation by Rigiflex dilator (n=10), BT sclerotherapy needle four quadrants lower esophageal sphincter...

The expression of cyclin D1 protein in tumour sections from 81 patients with epithelial ovarian cancer was analysed using immunohistochemistry. tumours that overexpressed more than 10% neoplastic cells were considered positive. Thus overexpression observed 72/81 (89%) the cases examined. Protein detected both nucleus and cytoplasm 24/81 (30%) localized exclusively 48/81 (59%) tumours. Cyclin borderline invasive There no association between stage differentiation. Furthermore, correlation...

The reliability and applicability of colposcopically directed cervical punch biopsy was assessed in a sample 170 paired large loop excision transformation zone (LLETZ) specimens obtained from previously untreated women who had been selected for treatment on the basis cytology and/or colposcopic findings whom entire visible. A single taken immediately before LLETZ, all were reviewed by pathologist. Nine (5.3%) biopsies inadequate. In terms whether or not there intraepithelial neoplasia (CIN),...

Ovarian cancer accounts for the majority of deaths from gynaecological malignancy, and polymorphisms in genes encoding glutathione-S-transferase (GST) GSTP1 detoxifying enzymes may lead to variation detoxification carcinogens. We describe a study involving 81 women with invasive epithelial ovarian cancer. A number important clinical variables outcome data were obtained. genotyping was undertaken using PCR-based techniques, expression quantified immunohistochemistry (IHC). Cox's proportional...

Optimal management of the contralateral groin in patients with early-stage vulvar squamous cell carcinoma (VSCC) and a metastatic unilateral inguinal sentinel lymph node (SN) is unclear. We analyzed who participated GROINSS-V I or II to determine whether treatment can safely be omitted SN.We selected SN from databases. determined incidence additional non-SN metastases SN-metastasis underwent bilateral inguinofemoral lymphadenectomy (IFL). In those only ipsilateral no further treatment, we...

We have investigated the influence of CCND1 genotype on clinical outcome in 138 women with epithelial ovarian cancer. genotypes were identified from peripheral blood DNA by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis. Patient compared details including FIGO tumor stage, residual volume, histology and differentiation, response to chemotherapy, progression free interval, survival. observed no association between patient characteristics or...

The objective of this study was to determine whether the association between GSTM1 null/GSTTI null and survival in ovarian cancer is mediated by influence these genes on p53 expression. In 81 women with pure invasive cancer, GSTT1 genotypes were identified using polymerase chain reaction expression assessed immunohistochemistry. factors examined Cox's proportional hazards regression models. Performance status (P < 0.001), operative stage = 0.004), residual disease histologic subtype 0.05),...

Sentinel node (SN) biopsy is widely applied for treatment planning of cutaneous melanoma. However, using this strategy in female lower genital tract tumors has not yet been established. We report two cases, one each vulvar and vaginal melanoma who underwent SN review the available literature.
