Determination of tumour prognosis based on angiogenesis-related vascular patterns measured by fractal and syntactic structure analysis.

Aims: Intratumoural micro-vessel density (IMD) has recently been shown to be a valuable prognostic tool in many tumours. Yet, IMD does not take into account the spatial arrangement of the vessels, therefore only partly reflecting the angiogenic situation. In order to describe contextual vascular relationships more accurately, we have used fractal and syntactic structure analysis (SSA) based on computerised image processing to quantify micro-vascular hot spots.

Contrast-enhanced MR imaging of breast lesions and effect on treatment.

Purpose: To assess the value of local staging with preoperative magnetic resonance imaging (MRI) in patients with suspect breast lesions and the effect on therapeutic approach.

Materials And Methods: Two hundred and four consecutive women with suspect breast lesions on clinical examination (CE) and/or mammography (MX) and/or ultrasound (US) underwent preoperative contrast-enhanced MRI. Detection of multifocal, multicentric and bilateral breast cancer by all three imaging modalities was evaluated.

Massive infarction of a recurrent phyllodes tumor of the breast: MRI-findings.

We report the imaging findings in an infarcted phyllodes tumor of the breast. A 40-year-old woman presented ten months after surgery for a benign phyllodes tumour with a palpable lump under the scar. We performed clinical examination, mammography, sonography, and MRI.

Treatment policy of neuroendocrine small cell cancer of the cervix.

Small cell cancers of the cervix are very rare and aggressive tumours. It is difficult to manage these tumours. They are often diagnosed in an advanced stage and their prognosis is generally poor.

Enhancing area surrounding breast carcinoma on MR mammography: comparison with pathological examination.

The enhancing area surrounding breast carcinoma on MR mammography is correlated with findings from pathological examination. We studied 194 patients with breast cancer who underwent preoperative MR mammography. Of all malignant lesions presenting with an enhancing surrounding area on MR mammography, morphologic features including long spicules, a ductal pattern, diffuse enhancement or nodules were evaluated and compared with histopathological examination.

Primary ovarian small cell carcinoma of the pulmonary type: a case report and review of the literature.

Small cell carcinoma of the ovary is a rare type of ovarian carcinoma with a poor prognosis. Two types should be distinguished: the hypercalcemic type and the pulmonary type. We report the case history of a 54-year-old woman with both a Stage IIIC small cell carcinoma, pulmonary type and a well-differentiated endometrioid adenocarcinoma of the left ovary in combination with a Brenner tumor in the right ovary.

Preoperative breast MRI in patients with invasive lobular breast cancer.

To investigate the use of MRI in preoperative characterization of invasive lobular breast cancer (ILC) and in detection of multifocal/multicentric disease. We retrospectively reviewed T1-weighted FLASH 3D precontrast and postcontrast MR images together with subtraction images of 26 women with histopathologically proven invasive lobular cancer. Two experienced radiologists described tumor patterns of ILC independently.

Uterine inversion by a mixed müllerian tumor of the corpus.

Mixed müllerian tumors (MMT) of the uterus have been reported following the use of tamoxifen. Rarely, these tumors lead to an uterine inversion. The surgical approach of a uterine inversion forms a therapeutic challenge.

Can cervical cancer screening be stopped at 50? The prevalence of HPV in elderly women.

Although the relation between cervical cancer and the human papillomavirus (HPV) has been established beyond doubt, the introduction of HPV detection in cervical cancer screening is halted, primarily by the high rate of false positivity in relation to morbidity, since the majority of women infected with HPV will not develop lesions. To counteract overconsumption of cervical cancer screening in elderly women, we wanted to test the hypothesis that women of 50 years or older who are HPV-negative and have a cytologically normal smear might be encouraged to refrain from further screening. As a first step, the prevalence of high-risk HPV in a population of 1,936 women of 50 years and older was investigated.

Primary squamous cell carcinoma of the breast.

Primary squamous cell carcinoma of the breast is a rare neoplasm. We herein report two cases of primary squamous cell carcinoma of the breast, each with a different clinical manifestation. A 75-year-old patient with bilateral breast cancer and a 73-year-old woman with a mastitis carcinomatosa.

Ovarian tumour: ovarian pregnancy. Diagnosis and management.

An ovarian mass in a premenopausal patient has many differential diagnoses. In young patients the mass is most likely to be benign. Sometimes patients with an abdominal mass will present as acute abdomen.

Laparoscopic surgery and port-site metastases: routine measurements to reduce the risk.

More and more malignancies are identified by laparoscopy. Concerns have been risen about the safety of these procedures, especially after the publications on trocar metastases. General laparoscopic techniques should include safety measures in order to reduce the risk of implantation metastasis.

The correlation of preoperative CT, MR imaging, and clinical staging (FIGO) with histopathology findings in primary cervical carcinoma.

The aim of this study was to compare the preoperative findings of abdominal/pelvic CT and MRI with the preoperative clinical International Federation of Obstetrics and Gynecology (FIGO) staging and postoperative pathology report in patients with primary cancer of the cervix. Thirty-six patients with surgical-pathological proven primary cancer of the cervix were retrospectively studied for preoperative staging by clinical examination, CT, and MR imaging. Studied parameters for preoperative staging were the presence of tumor, tumor extension into the parametrial tissue, pelvic wall, adjacent organs, and lymph nodes.
