AbstractAbstract
[en] Endometrial cancer is the fourth most common malignancy in women, with most cases being classified as early stage endometrioid tumors that carry a favorable prognosis. The endometrial serous histological subtype (ESC), however, while only accounting for 10% of all endometrial cancers is responsible for a disproportionate number of deaths. Unlike the estrogen-dependent, well differentiated endometrioid tumors, which are commonly associated with a younger age of onset, ESCs are estrogen-independent and tend to present at an advanced stage and in older women. Treatment for ESC entails aggressive surgery and multimodal adjuvant therapy. In this review, we describe the clinical behavior, molecular aspects, and treatment strategies for ESC

AbstractAbstract
[en] Human carcinomas frequently exhibit significant stromal reactions such as the so-called “desmoplastic stroma” or “reactive stroma”, which is characterised by the existence of large numbers of stromal cells and extracellular matrix proteins. Carcinoma-associated fibroblasts (CAFs), which are rich in activated fibroblast populations exemplified by myofibroblasts, are among the predominant cell types present within the tumour-associated stroma. Increased numbers of stromal myofibroblasts are often associated with high-grade malignancies with poor prognoses in humans. CAF myofibroblasts possess abilities to promote primary tumour development, growth and progression by stimulating the processes of neoangiogenesis as well as tumour cell proliferation, survival, migration and invasion. Moreover, it has been demonstrated that CAFs serve as a niche supporting the metastatic colonisation of disseminated carcinoma cells in distant organs. Their contribution to primary and secondary malignancies makes these fibroblasts a potential therapeutic target and they also appear to be relevant to the development of drug resistance and tumour recurrence. This review summarises our current knowledge of tumour-promoting CAFs and discusses the therapeutic feasibility of targeting these cells as well as disrupting heterotypic interactions with other cell types in tumours that may improve the efficacy of current anti-tumour therapies

AbstractAbstract
[en] Our aim was to assess the value of diffusion tensor imaging (DTI) in patients with partial intractable epilepsy. We used DTI (25 non-collinear directions) in 15 patients with a cortical lesion on conventional MRI. Fractional anisotropy (FA) was measured in the internal capsule, and in the normal-appearing white matter (WM), adjacent tothe lesion, and away from the lesion, at a set distance of 2-3 cm. In each patient, increased or decreased FA measurements were those that varied from mirror values using an arbitrary 10% threshold. Over the whole population, ipsi- and contralateral FA measurements were also compared using a Wilcoxon test (p<0.05). Over the whole population, FA was significantly reduced in the WM adjacent to and away from the lesion, whilst being normal in the internal capsule. FA was reduced by more than 10% in the WM adjacent to and distant from the lesion in 13 and 12 patients respectively. For nine of the ten patients for whom the surgical resection encompassed the limits of the lesion on conventional MRI, histological data showed WM alterations (gliosis, axonal loss, abnormal cells). DTI often reveals WM abnormalities that are undetected on conventional MRI in patients with partial intractable epilepsy. (orig.)

AbstractAbstract
[en] Full text: Locally recurrent disease in patients with melanoma is usually defined as cutaneous or subcutaneous arising within 5 cm of the primary site after complete excision of the primary lesion. It may represent residual disease not excised with the primary tumor or the outgrowth of the satellite lesions, which are common with melanoma. Lymphatic mapping and sentinel lymph node (SLN) biopsy is highly accurate in staging nodal basins at risk of regional metastases in primary melanoma patients and identifies those who may benefit from earlier lymphadenectomy. Our purpose was to evaluate the efficacy of sentinel lymph node mapping and biopsy in local recurrence of cutaneous melanoma when the primary lesion was less than 1.0mm thick. Three patients with local recurrence of cutaneous melanoma underwent sentinel lymph node mapping and biopsy. All patients underwent preoperative lymphoscintigraphy to identify the lymphatic basin and the site of the sentinel node. All patients subsequently underwent intra-operative lymphatic mapping and selective lymph node biopsy with vital blue dye and hand-held gamma probe. Excised SLN were analysed by conventional histological staining (H and E) and immunohistochemical staining. In all patients the lymphatic mapping and sentinel lymph node biopsy was successful. The SLN biopsy was negative in two patients and positive in one who underwent therapeutic lymph node dissection. Our results indicate that the SLN mapping and biopsy is also possible in patients having local recurrence of cutaneous melanoma. Although long-term results are not available, early results are promising. (author)

AbstractAbstract
[en] A brief historical survey of the interpretations of some radioautographic results was carried out. In practice, the study of labelled products within tissues has started by simple observations, but today, often involves sophisticated analyses. The three stages that may be delineated in this type of work were described: the initial qualitative assessment, the period when quantitation of the data became essential and finally, the application of complex analytical methods to radioautographic interpretation

AbstractAbstract
[en] To perform a semiautomated software-based comparison of invasive breast carcinoma dynamic enhancement patterns in MR mammography with histological prognostic factors considering whole lesion volumes. A total of 128 patients with 145 invasive breast carcinomas underwent dynamic MR mammography. Kinetic features from the invasive breast lesions were obtained using commercially available software to automatically assess volume enhancement characteristics of a manually chosen lesion. Findings were compared with histological factors determining tumour aggressiveness (lymph node status, LN; oestrogen/progesterone receptor (ER/PR) status; HER-2/neu status; tumour grade) by using nonparametric rank tests and binary logistic regression analysis (BLRA). Volume enhancement characteristics were significantly influenced by LN, ER/PR and HER-2/neu status (P<0.05). BLRA implied that total lesion and plateau voxel volume were independent predictors of ER/PR and HER-2/neu status. Strongest initial enhancement predicted negative ER/PR, and time to peak of the most suspect curve was inversely correlated with positive LN status. On the other hand, no statistical significance could be observed between histological tumour grading and kinetic features. Histopathological criteria associated with poor prognosis lead to significantly more aggressive dynamic enhancement patterns in MR mammography. In this study, higher lesion volumes as well as higher and earlier initial enhancement were independent covariates predicting higher tumour aggressiveness. (orig.)

AbstractAbstract
[en] This study was concerned with the representation and description of the rib cartilage of the dog and the abnormalities of such by means of radiological, computer tomographic, pathoanatomical and histological examinations and the comparison of the results of the various examination methods. The study material consisted of 100 ventral thorax walls of dogs of different ages and breeds. In 39 of the subjects, no abnormalities of rib cartilage other than unremarkable calcification were observed. Among the subjects, there were 11 puppies (0-3 months), whose rib cartilage appeared soft tissue dense due to the absence of calcification, 14 juvenile animals (4-18 months), the rib cartilage of which showed a typical finely granulated structure, and 14 adult dogs (over 18 months), whose rib cartilage exhibited a homogeneous to net-like calcified appearance. In the calcified rib cartilage, the histological section showed a centrally located spongiosa rod surrounded by a hyaline cartilage shell. The calcification tendency of the first pair of rib cartilage was remarkable: in 70 dogs, the first pair of rib cartilage remained uncalcified despite calcification of the other rib cartilage. Sixty-one dogs exhibited rib cartilage abnormalities. According to the radiological appearance of the abnormalities, they were divided into groups and their incidence was calculated. Abnormalities seen included interruption in the continuity of the calcified rib cartilage with and without callus formation, enlargement of rib cartilage, cuff formation, and abnormalities on the Articulationes sternocostales (projections in or around articulations, calcified and fractured joint surfaces). In addition, remarkable calcification patterns were observed. By means of CT examination the densities of the tissue forming the various abnormalities was determined. In the course of the pathoanatomical examination, it was shown that the interruptions in continuity with callus and the various enlarged areas of the rib cartilage allowed motion. Histological examination showed that these interruptions in continuity and the various enlarged areas of rib cartilage were pseudoarthroses or their precursors. In addition to the 100 specimens used, 1010 radiographs from the archive of the University Clinic of Radiology were evaluated. The fact that certain dog breeds (German Shepherd, Spaniel, Dachshund) are predisposed to developing rib cartilage abnormalities and that the incidence of rib cartilage abnormalities is higher at an age of 7 years or more became apparent through the archive evaluation.
