[Breast adenocarcinoma: critical analysis of sentinel lymph node histopathological results of 542 procedures].

Between February 2001 and March 2003, 542 sentinel lymph node procedures were performed for localised breast carcinoma (T0-T1, N0, M0) without any previous treatment. Frozen sections were performed in 515 cases and they did not reveal metastases in 446 cases. Fifty-two micrometastases < 2 mm and 18 macrometastases were reported by definitive histopathological exam.

The human H19 gene is frequently overexpressed in myometrium and stroma during pathological endometrial proliferative events.

We studied the patterns of H19 expression in normal, hyperplastic and neoplastic human uterine tissues. H19 RNAs were detected by an in situ hybridisation technique (ISH). In both normal and pathological conditions, H19 was expressed in stromal and myometrial cells, but never in epithelial cells.

Head and neck soft tissue sarcomas of adult: prognostic value of surgery in multimodal therapeutic approach.

Adult head and neck soft tissue sarcomas (AHNSTS) are rare, and data concerning treatment results are spare. To assess clinico-pathological characteristics, management prognostic factors, and survival of AHNSTS, we reviewed our experience of 28 recent successive new cases. Data were collected from a retrospective database (1997-2002).

[Frequency of genetic diseases and cancer antecedents in 493 adults with visceral or soft tissue sarcomas].

Little is known about epidemiology of adults soft tissue and visceral sarcomas (ASTS). The frequency of previous cancers and associated genetic diseases has been analyzed out of 493 ASTS, treated between 1997 and 2002 at Oscar Lambret Cancer Center. Median age is 51, sex ratio is close to 1.
