[Fallopian tube adenocarcinoma: synchronous neoplasia and severe uterine endocervical squamous epithelial dysplasia]. / Adenocarcinoma della tuba di Fallopio: neoplasia sincrona a displasia epiteliale squamosa severa endocervicale uterina.

We report a rare case of primary carcinoma of the fallopian tube. A 72-year-old post-menopausal woman presenting with abnormal secretion of blood-stained liquid, underwent surgery because of findings of atypical squamous cells (ASCUS) on a routine Papanicolaou smear. The histological diagnosis on cervical biopsy was of CIN 3. Adenocarcinoma of the Fallopian tube was incidentally found.

Detection of Lewis(a) antigen in sera of ovarian carcinoma patients by MOv2-MOv8 double-determinant radioimmunoassay.

The monoclonal antibodies MOv2 and MOv8, raised against ovarian carcinoma, were found to be directed against two non-crossreacting epitopes expressed on the same molecule. Immunochemical analysis of the MOv8 recognized epitope showed that the Le(a) oligosaccharide, or commercial anti-Le(a) MAb, but not the anti-Le(b) MAb, prevented Ov8 binding to the reference target cell line (SW626), indicating that it is carried by the Le(a) antigen. Since we previously reported that MOv2 also recognises the Le(a) antigen, these data suggest that Mov8 and Mov2 were directed against different epitopes on the same oligosaccharide chain. Bearing in mind the knowledge of the biochemical nature of the monoclonal antibody recognized epitopes (CaMOv2 and CaMOv8), the presence of the circulating molecules recognized by them was analyzed by double determinant immunoradiometric assay (DDIRMA) in 103 sera from ovarian carcinoma patients. Patients with clinical evidence of the disease (ED) with MOv2 and MOv8 reactive and negative tumors had sera reactivity in 67% and 19% respectively. Also, 26% of the patients with no clinical evidence of disease (NED) had positive sera. When we investigated the relationship between MOv2-MOv8 DDIRMA sera positivity and red blood cells (RBC) Lewis phenotype, a strong correlation was found between the Le(a)+ phenotype and DDIRMA sera reactivity in healthy donors (6/6) and in ovarian carcinoma patients (9/10) whatever their clinical condition. No Le(a)- healthy donors gave evidence of MOv2-MOv8 reactive sera. In contrast, 33% and 57% of the sera from ED carcinoma patients with respectively Lea-b+ and Lea-b- phenotype were positive.(ABSTRACT TRUNCATED AT 250 WORDS)

Preoperative staging of primary breast cancer. A multicentric study.

This article reports on a consecutive series of 3627 breast cancer (BC) patients undergoing preoperative staging by chest x-ray (CXR), bone x-ray (BXR) or bone scintigraphy (BS), and liver ecography (LE) or liver scintigraphy (LS). The detection rate (DR) of preclinical asymptomatic distant metastases depended on the T and N category (TNM classification system), and was very low (CXR: 0.30%, BXR: 0.64%, BS: 0.90%, LE: 0.24%, LS: 0.23%). The sensitivity, determined after a 6-month follow-up, was below 0.50% for all tests. The highest value (0.48%) was recorded for BS, which also had the lowest specificity (0.95%). The entire preoperative staging policy using the studied tests seems questionable due to poor sensitivity and an extremely low DR of distant metastases.
