It expresses markers associated with endothelial, haematopoietic and mesenchymal lineages. We have previously shown that the cells forming the capillary endothelium of proliferating IH express cell surface markers and transcriptions factors consistent with it being a haemogenic endothelium. Objectives We wished to determine whether the expression of transcription factors associated with the erythroid lineage was of physiological relevance and sufficient for IH tissue cultured in vitro to undergo erythropoiesis. Methods Immunohistochemical staining of paraffin-embedded sections of proliferating IHs was undertaken and expression of the embryonically associated haemoglobin zeta (HBZ) chain and the erythropoietin receptor (EPO-R) was determined. Relative expression of mRNA encoding these proteins was determined by quantitative reverse transcription-polymerase chain reaction using snap-frozen biopsy samples. Differentiation towards erythrocytes was investigated using freshly resected tissue cultured as explants in Matrigel. Results The endothelium of the microvessels, but not the pericyte layer, was strongly immunoreactive for the EPO-R and the embryonically associated HBZ chain. Abundant expression of transcripts encoding these proteins was also detected, corroborating the immunohistochemical staining. When tissue was grown in culture the cells emanating from IH explants were able to generate enucleated erythrocytes in vitro. The erythrocytes were immunoreactive for the erythrocyte-specific marker glycophorin A. Conclusions The microvessels in IH are a functional haemogenic endothelium that expresses the embryonically associated HBZ chain and is able to form erythrocytes in vitro. IH thus represents a possible extramedullary site for tumour-associated primitive erythropoiesis."],["dc.identifier.doi","10.1111/j.1365-2133.2010.10188.x"],["dc.identifier.isi","000289898200028"],["dc.identifier.pmid","21166659"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/23170"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","0007-0963"],["dc.title","Successful treatment of classic kaposi sarcoma with low-dose intramuscular immunoglobulins"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.subtype","letter_note"],["dspace.entity.type","Publication"]]

Descriptive statistics, Kaplan-Meier estimates, logistic regression analysis and the Cox proportional hazards model were used to study a population of 2,268 consecutive patients from three German melanoma centers. Younger age was significantly related to less advanced primary tumors. Nevertheless, patients younger than 40 years of age had a twofold risk of being SLN-positive (p < 0.000001). Of the young patients with primary melanomas with a thickness of 0.76 mm to 1.0 mm, 19.7% were SLN-positive. Using multivariate analysis, younger age, increasing Breslow thickness, ulceration and male sex were significantly related to a higher probability of SLN-metastasis. During follow-up, older patients displayed a significantly increased risk of in-transit recurrences (p = 0.000002) and lymph node recurrences (p = 0.0004). With respect to melanoma specific overall survival the patient's age was highly significant in the multivariate analysis. The unfavorable effect of being older was significant in the subgroups with positive and negative SLNs. Age remained also significant for the survival after the onset of distant metastases (p = 0.002). In conclusion, the patient's age is a strong and independent predictor of melanoma-specific survival in patients with localized melanomas, in patients with positive SLNs and after the onset of distant metastases.

Descriptive statistics, Kaplan-Meier estimates and Cox proportional hazard models were used to study retrospectively a population of 2302 consecutive melanoma patients from three German melanoma centres undergoing SLNE. Approximately 10% of the patients (N=237) had a primary melanoma located at the head or neck (HNM). In both the SLN-positive and SLN-negative subpopulation, patients with HNM were significantly older, more frequently men and had thicker primaries compared with patients with tumours in other locations. The proportion of positive SLNs was lower in HNM compared with other locations of the primary (20 vs. 26%, P=0.048). The false-negative rate was higher in HNM (17.5 vs. 8.4%, P=0.05). In patients with HNM, the SLN status was a significant factor for recurrence-free survival but not for overall survival. SLN-negative HNM patients had a significantly worse overall survival than the SLN negatives with primaries at other sites, whereas the prognosis of the SLN-positive patients was similar in both groups. The prevalence of lymph node metastases after SLNE is lower in patients with HNM compared with other melanoma locations.

However, this aspect is of interest, since sentinel lymphonodectomy (SLNE) has been suspected of causing LCM by inducing entrapment of melanoma cells. We analysed 244 patients with SLNE and compared the data with 199 patients treated with delayed lymph node dissection (DLND) for clinically palpable metastases. Analysis of both groups commenced at the time of excision of the primary tumour, using the Kaplan-Meier method. LCM that appeared as a first recurrence, as well as the overall probability of developing LCM, were recorded. For sentinel-negative patients with a primary melanoma > 1 mm thick, the 5-year probability of developing LCM as a first recurrence was 6.9 +/- 0.02% (standard error of the mean (SEM)). The probability was 17.6 +/- 0.03% in the DLND group. Comparing the two node-positive subgroups, the probability of developing LCM as a first recurrence was significantly higher in patients with positive SLNE (27.3 +/- 0.05%, P = 0.03). However, the 5-year overall probability of developing LCM did not differ significantly in the node-positive groups (33.3% in the DLND group vs. 33.7% in patients with positive sentinel lymph nodes (SLNs)). Since early excision of lymphatic metastases by SLNE avoids nodal recurrences, thereby prolonging the recurrence-free interval, the chance of LCM to manifest as a first recurrence should inevitably increase. However, the overall in-transit probability is not increased after SLNE. (c) 2004 Elsevier Ltd.
