BACKGROUND Implantation of the zygote outside the uterine cavity occurs in 2% of all pregnancies. The product of conception can be removed safely by laparoscopic surgery and be submitted for histological examination. The rate of ectopic pregnancies has increased from 0.5% in 1970 to 2% today. The prevalence of ectopic pregnancy in all women presenting to an(More)
BACKGROUND Pharmacological activation of cannabinoid receptors elicits antitumoral responses in different cancer models. However, the biological role of these receptors in tumor physio-pathology is still unknown. METHODS We analyzed CB2 cannabinoid receptor protein expression in two series of 166 and 483 breast tumor samples operated in the University(More)
To increase the knowledge about the development of pancreatic ductal adenocarcinoma, (PDAC) detailed analysis of the tumor progression is required. To identify proteins differentially expressed in the pancreatic intraepithelial neoplasia (PanIN), the precursor lesions of PDAC, we conducted a quantitative proteome study on microdissected PanIN cells.(More)
OBJECTIVE To evaluate the metastatic risk of pT1 G2 squamous cell carcinoma (SCC) of the penis. PATIENTS AND METHODS We retrospectively reviewed 20 patients with pT1 G2 penile SCC and determined their groin status at first presentation, their nodal status after inguinal lymph node dissection and their follow-up for at least 18 months. RESULTS Four of(More)
Although tumor surgery aims for a complete resection respecting tumor-specific safety distance, in many cases the most peripheral part, the invasion front, remains in situ. Tumor cells at the tumor margin lose epithelial properties and acquire features of mesenchymal cells. The process of epithelial-to-mesenchymal transition (EMT) has been suggested to be(More)
EPIDEMIOLOGY Vulvar cancer can be classified into two groups according to predisposing factors: the first type correlates with a HPV infection and occurs mostly in younger patients. The second group is not HPV associated and occurs often in elderly women without neoplastic epithelial disorders. HISTOLOGY Squamous cell carcinoma (SCC) is the most common(More)
OBJECTIVES Endometriosis is a common gynaecological disease with clinical symptoms such as chronic pain, infertility and intra-abdominal adhesions. Different theories on the pathogenesis of endometriosis and especially its aggressive subtype with infiltrative growth have been discussed. The objective of this study is to evaluate differences in proliferation(More)
STUDY OBJECTIVE To evaluate 3 therapy strategies: hormone therapy, surgery, and combined treatment. DESIGN Prospective, randomized, controlled study (Canadian Task Force classification I). SETTING University-based teaching hospital. PATIENTS Four hundred fifty patients with genital endometriosis, aged 18 to 44 years, before first laparoscopy. (More)
Malignant melanoma of the urethra is a rare tumour that is difficult to diagnose and treat, resulting in a poor prognosis. In this paper, we present the case of a 65-year-old woman who was referred to a gynaecologist because of a urethral mass that mimicked a caruncle. The tumour was removed by local excision, and a pathological analysis revealed a(More)
