Role of pelvic lymphadenectomy in the management of stage I endometrial cancer: our experience.

OBJECTIVES: To estimate the prognostic value of pelvic-node removal on survival of patients affected by endometrial carcinoma at presurgical FIGO Stage I. METHODS: A retrospective analysis was performed on a total of 111 patients recruited from 1990 to 1996 at the S. Carlo di Nancy Hospital. Thirty-nine (35%) of them underwent a total hysterectomy and bilateral salpingo-oophorectomy with removal of the vaginal cuff (group 1), while 72 (65%) underwent a total hysterectomy combined with pelvic lymphadenectomy (group 2). Prognostic features including tumor grade, depth of myometrial invasion and histologic subtype. Survival rates were calculated with Cox and Kaplan analyses. RESULTS: Overall survival rate at five years was 91.2%. The survival rate of group 1 and group 2 was 89% and 92.8%, respectively which is not statistically significant. Stage, grade, histotype, age at diagnosis, and presence of positive lymph nodes did not show any significant prognostic value on survival probability. CONCLUSIONS: The survival rate for patients submitted to lymphadenectomy (group 2) was the same of patients who did not undergo this treatment (group 1). Nevertheless, pelvic lymphadenectomy in endometrial carcinoma at presurgical FIGO stage I was worthwhile as it allowed correct staging to be performed. The prediction of nodal disease based only on preoperative investigations (such as TC, NMR) is often inaccurate.

Immunohistochemical expression of human erythrocyte glucose transporter and fatty acid synthase in infiltrating breast carcinomas and adjacent typical/atypical hyperplastic or normal breast tissue.

To evaluate the immunohistochemical expression of GLUT1, human erythrocyte glucose transporter 1, and fatty acid synthase (FAS), 66 human breast carcinomas and adjacent peritumoral tissue were studied. GLUT1 and FAS were expressed in 53 and 61 carcinomas, in 17 and 14 typical/atypical hyperplastic tissues, and in 16 and 13 tissues adjacent to tumor normal breast tissue, respectively. Statistical analysis revealed association between invasive carcinomas, invasive carcinomas with in situ component and GLUT1 immunostaining. GLUT1 staining was associated with tumor grade, FAS with tumor stage, and GLUT1 and FAS coexpression with tumor grade. Controls expressed no immunostaining. GLUT1 and FAS are new markers involved in the biologic activities of cancer cells. GLUT1 and FAS coexpression may indicate increased use of energy by the neoplastic cells correlated with poorly differentiated features and aggressive behavior. The innovative finding that GLUT1 and FAS are observed in mammary carcinoma adjacent nonneoplastic tissues may suggest a role in detecting initial phases of breast carcinogenesis.

[Radical trachelectomy with lymphadenectomy]. / La trachelectomia radicale con linfoadenectomia.

Radical trachelectomy was described for the first time by Dargent in 1987 as an alternative to the traditional radical hysterectomy; it led to a changed procedure in therapy for early cervical cancer in young women who want to preserve their fertility. With this technique it is possible to remove the uterine cervix and parametrius and at the same time preserve the upper part of the cervical canal and uterus. Only a low-risk subset of young patients with early cancer of the cervix are considered eligible for this treatment; to select them histological and clinical staging of the lesion are the most important criteria. We describe the cases of three patients treated with radical trachelectomy between June 1997 and March 1998 in our Institute, reporting in detail the surgical procedure and the results.

Infiltrating lobular carcinoma of the breast (ILC). Diagnostic and therapeutic aspects.

Invasive lobular carcinoma of the breast (ILC) is the second most common form of mammary neoplasm after ductal carcinoma. Due to its histological features, characterised by a diffuse infiltration of the tissue by malignant cells with scarce fibrotic reaction, lobular carcinoma often presents clinical and instrumental diagnostic difficulties. The Authors present a retrospective series of 28 patients with lobular carcinoma, with special regard to the diagnostic work-up. Clinical examination misdiagnosed 10 cases, in which only a mild thickening of the breast parenchyma was present. Mammographic false negatives were 21.4% (6 cases). Ultrasonography allowed correct diagnosis in 5 out of these 6 cases. Fine needle aspiration (FNA) had low sensitivity (33% false negatives). ILC constitutes a diagnostic challenge, often requiring the combination of multiple diagnostic tools.
