Abstract
We describe the case of a 76-year-old male presenting a thrombocytopenia at the diagnosis of Hodgkin disease. Basing on bone marrow biopsy and evolution, we diagnosed an immune thrombocytopenia and treated with intravenous gammaglobulins. The platelet count normalized in a few days under this therapy. Immune thrombocytopenia purpura (ITP) is a rare complication of Hodgkin disease (HD). It seems to be due to the production of antibodies directed against platelet membrane proteins. The patient's and the lymphoma's characteristics are not predictive for it to happen. The evolution of HD is also not influenced by its occurrence. Various treatments (including corticoids and immunomodulating agents) have been tried with different efficiencies.

Abstract
Glomic tumours are rare tumours usually found on the fingertips, particularly the nail-beds, but they can occur anywhere in the body. The first gastric glomic tumour was identified in 1942 and reported with two other cases in 1951 by Key et al. At present, 100 cases of glomic tumour of the stomach have been reported in the literature. We report a case of benign gastric glomic tumour treated by laparoscopic surgery. This type of tumour is most frequently benign but cases of malignity have been described. The preoperative assessment is important.

Abstract
BACKGROUND The relationships between EGF-R and c-erbB-2 with other factors involved in tumour regulation are not well understood. The aim of this study was to correlate the expression of these markers with tumour proliferation. MATERIALS AND METHODS The presence of EGF-R, c-erbB-2 and Ki-67 was evaluated by immunohistochemistry in non-small cell lung cancer (NSCLC) and preneoplastic lesions. RESULTS Forty-two percent of the tumours were positive for EGF-R, 22% for c-erbB-2 and 97% for Ki-67. No statistically significant correlation was found between EGF-R and Ki-67, EGF-R and c-erbB-2 or between c-erbB-2 and Ki-67. With regards to Ki-67, a significant difference in survival was noted in favour of patients who did not express the marker. In preneoplastic lesions, most of the low-grade lesions showed neither EGF-R nor Ki-67 staining. In contrast, most of the high-grade lesions stained positively for these proteins. CONCLUSION EGF-R and c-erbB-2 do not seem to be correlated with Ki-67 in NSCLC.

Abstract
Fragile histidine triad (FHIT) is a tumour suppressor gene, which is altered in a variety of epithelial tumours, including lung cancer. Biochemical and functional pathways of its tumourigenicity are not yet understood. Its role in tumour proliferation is particularly controversial. The purpose of this study was to correlate the expression of FHIT protein in nonsmall cell lung cancer (NSCLC) with tumour proliferation as estimated by Ki-67 antigen and with p53, a suppressor gene. FHIT, Ki-67 and p53 expression were evaluated by immunohistochemistry in 119 resected NSCLC. Altogether, 58 tumours were negative (expression <10%) for FHIT. The median expression in tumours was 15% positive cells, in comparison with 100% in normal matched lung tissue. The expression was as strong as in normal tissue in only 19 cases. FHIT expression was significantly lower in squamous cell carcinoma (SCC) (5%) than in adenocarcinoma (ADC) (64%). The median expression of Ki-67 was 20% and 69% of tumours were positives (expression >10%). Ki-67 expression was significantly higher in SCC (33.3%) than in ADC (10%). The loss of FHIT protein was not correlated with the expression of p53 (median: 7.5%, 58% of positive tumours for a cut-off of 10% of positive cells) or Ki-67. But percentage of labelled cells for p53 and Ki-67 were significantly correlated. The results suggest that for fragile histidine triad, the pathway of tumourigenesis is independent of p53 and of tumoural proliferation, as reported previously in vitro.

Abstract
BACKGROUND/AIM Proliferative vitreoretinopathy (PVR) and macular pucker (MP) vitreoretinal membranes are caused by abnormal cell migration. By their role in chemotactism, chemokine receptors represent good candidates to sustain this process. The authors thus investigated the expression of one of them, CXCR4, in these pathologies. METHODS Three PVR and four MP membranes were surgically removed and processed for immunochemical studies with antibodies for CXCR4, cytokeratins or smooth muscle actin. RESULTS CXCR4 expression was found in all membranes. There was no relation between severity of PVR or MP and presence of CXCR4. In addition, there was no difference in CXCR4 expression between MP and PVR. CONCLUSION CXCR4 is expressed in PVR and MP. Further experiments are needed to test if CXCR4 and other chemokine receptors are implicated in vitreoretinal membrane formation.

Abstract
When many lymph nodes are found by using lymphoscintigraphic techniques performed to detect the sentinel lymph nodes (SLNs) in breast cancer, it is usual to find that the 'hottest' SLN is not always the node that is pathologically positive (pN+). Various criteria have been proposed to define which radioactive lymph nodes should be removed. In order to determine the frequency with which the hottest SLN 'fails' to be pN+, and to determine which criteria best define the radioactive lymph node to be removed, we reviewed and analysed our cases in which more than one SLN was detected and where there was also at least one pN+ node. From a series of 181 patients, 40 were selected. In 11 of these 40 cases (27.5%), the hottest SLN was not pN+. Radioactivity levels in the pN+SLN of these 11 patients ranged from 2% to 94% of the activity of the hottest SLN. Twenty-one patients (52.5%) showed only micrometastatic (pN1a) disease in one or more SLNs. In four of these patients (19%) the pN1a SLN was not the hottest node. Two of the patients had radioactivity levels in the pN+SLN which were more than 50% of that of the hottest SLN. In another two of these patients (9.5%), radioactivity levels were lower than 50% of that of the hottest node (respectively, 38% and 2%). However, in these two last cases, the first and hottest SLN removed surgically was found, by the pathologist, to consist of six nodes. Macrometastases (dimensions greater than 2 mm) were found in 19 patients. In 12 of these patients, the hottest SLN was macrometastatic although macrometastases and/or micrometastases were found in other 'cooler' SLNs in four of them. In another seven of these patients (36.8%), macrometastases were found in SLNs with radioactive levels lower than 51% of that of the hottest node. One patient (with three SLNs) out of the 40 (2.5%) had one SLN pN+ with less than 10% of that of the hottest. In fact, it contained only one micrometastasis and its activity was equal to 2%. Upon pathological examination, however, the hottest lymph 'node' was found to consist of six nodes. It is concluded that, with four intra-mammary and peritumoural injections of 99mTc labelled nanosized colloids of Human Serum Albumin (Nanocoll R: Sorin: 74 MBq and 0.05 mg per injection) performed 18-24 h before using a gamma probe to detect the SLNs, the hottest SLN was not the pathologically positive node in 27.5% of patients in our series. By using the activity in the hottest SLN as the reference point, and 10% of this activity as the lower threshold for removing active SLNs, the sensitivity of the technique is 97.5%.

Abstract
The 1999 World Health Organization/International Association for the Study of Lung Cancer histological classification of preneoplastic bronchial lesions has been shown to be reproducible but little is known about its biological significance. The current study evaluated the correspondence between the morphological changes of the bronchial epithelium and epidermal growth factor receptor (EGF-R) expression. Thirteen normal bronchial epithelia, 19 hyperplasia, 16 metaplasia, 10 mild dysplasia, one moderate dysplasia, 10 severe dysplasia (SD), 14 carcinoma in situ (CIS) and 11 microinvasive tumours were assessed. A global EGF-R score obtained by the sum of the positivity score plus the EGF-R staining intensity score was calculated for each lesion. A global EGF-R score of >5 was reached only in one metaplasia, in six SD, in six CIS and in six microinvasive tumours. There was no difference in EGF-R expression between normal, hyperplastic and metaplastic epithelia versus mild dysplasia or between severe dysplasia versus CIS and microinvasive tumours but there was a statistically significant difference between mild versus severe dysplasia. This study demonstrates that epidermal growth factor receptor expression rate changes with the stage of the bronchial lesion, increasing from normal epithelium to carcinoma in situ and microinvasive tumours with a statistically significant difference between mild versus severe dysplasia.

Abstract
The prognostic value of epidermal growth factor receptor (EGF-R) for survival of patients with lung cancer remains controversial. The authors performed a systematic review of the literature in order to clarify its impact. Published studies were identified using an electronic search in order to aggregate the available survival results, after a methodological assessment using a scale specifically designed by the European Lung Cancer Working Party (ELCWP). To be eligible, a study had to have dealt with EGF-R assessment in lung cancer patients on the primary site and to have analysed survival according to EGF-R expression. Among the 16 eligible studies, 14 assessed any nonsmall-cell lung cancer (NSCLC) subtype, one adenocarcinoma only and one squamous-cell carcinoma only. The overall median quality score was 56.3%, with no significant difference either between studies assessable or not assessable for meta-analysis or between studies with significant and nonsignificant results. One individual trial reported a survival benefit for patients with EGF-R expression, three a survival disadvantage and 12 no statistically significant difference. Eleven studies (2,185 patients) provided sufficient data to allow a meta-analysis of the survival results. EGF-R expression positivity was determined according to the cut-off as determined by the authors. The meta-analysis showed that EGF-R expression was not a statistically significant prognostic factor for survival in NSCLC. In the subgroup of studies using immunohistochemistry, statistical tests reached a significant level against EGF-R. Epidermal growth factor receptor might be a poor prognostic factor for survival in nonsmall-cell lung cancer. The amplitude of the impact is small, however, and may be subject to publication bias.

Abstract
The process of angiogenesis is an important factor in tumour development. One of the principal factors implicated in this process is vascular endothelial growth factor (VEGF) which induces, among other things, an increase in vascular permeability. We have undertaken a systematic review of the English and French literature in order to clarify its effect on the survival of patients with small cell (SCLC) and non-small cell (NSCLC) lung cancer. To be eligible studies had to deal with the the evaluation of VEGF or its receptors in lung cancer and describe the relationship of their expression to survival. The survival figures were subject to meta-analysis after a methodological evaluation by means of a specific numerical scale evaluating the design of the study, the methodology (including laboratory techniques), and the analysis of results. Among the 20 studies selected 15 identified VEGF expression, using univariate analysis, as a statistically significant indicator of poor prognosis. 17 reported sufficient data to allow aggregation of the survival figures, of which 15 were devoted to NSCLC (1,549 patients). The median overall methodological score was 48.3% (range 21.8-72.4%), without significant difference (p=0.63) between studies eligible or non-eligible for meta-analysis. The meta-analysis, using the authors' threshold of positivity for VEGF, showed that VEGF is an unfavourable prognostic factor in NSCLC (HR=1.48; 95% confidence interval 1.27-1.72). The data were insufficient to determine the prognostic value of VEGF in SCLC and that of its two receptors Flt-1 and KDR, with 1, 2 and 1 published studies respectively. In conclusion the expression of VEGF in MSCLC is a factor indicating a poor prognosis.

Abstract
OBJECTIVE Initially considered as an inhibitor of angiogenesis, the role of thrombospondin is currently controversial. The primary purpose of our study was to determine the expression of thrombospondin (TSP) in invasive lung tumours. The secondary objectives were to investigate its relationship with other factors related to angiogenesis and to assess their clinicopathological significance. MATERIALS AND METHODS From January 1993 to September 1998, we collected non-small cell lung cancer (NSCLC) and normal nearby-matched tissues from surgical specimens of 64 patients. Using these specimens, we assessed the expression of TSP by immunohistochemistry with monoclonal antibody to human TSP (clone 11.4). This expression was also correlated with other factors directly or indirectly related to angiogenesis:p53, Ki-67 as proliferation factor and microvessel count determined with anti-CD-31 antibody. RESULTS The resected tumours (stages I-IIIB) consisted of 30 adenocarcinomas, 24 squamous cell carcinomas, 5 bronchioalveolar carcinomas, 4 adenosquamous carcinomas and 1undifferentiated NSCLC. The mean values of TSP expression in neoplastic and normal related tissues were 63.08% and 86.57 %, respectively. This difference was statistically significant (p = 0.02). There was a higher level of variability of TSP expression between tumours than between normal tissues. The expression of TSP in NSCLC was statistically correlated to the expression of TSP in normal matched tissues (coefficient correLation rate = 0.31, p<0.01). The median expression of p53, Ki-67 and microvessel count in tumours was 45.00%, 38.80% and 8.33%, respectively. The correlations between TSP and the other biological variables and between these latter variables themselves were not statistically significant. No statistically significant difference was observed in survival according to TSP expression. CONCLUSION TSP appeared to be decreased in NSCLC in comparison with normal matched tissue. The TSP expression was not correlated with the other studied variables and was not associated with a significant difference in survival.

Abstract
Chromosomic aberrations play a major role in the initiation and the progression of benign as well as malignant tumors. In particular, trisomy 12 is frequently observed in female genitourinary tract tumors and constitutes a recurrent and often unique anomaly in stromal ovarian tumors such as fibrothecomas. Today, the genetic analysis of fresh or fixed solid tumors is enabled by the fluorescent in situ hybridization method (FISH). Using FISH and/or conventional cytogenetics, we analysed 12 ovarian stromal tumors (6 fibromas, 3 fibro thecomas and 3 thecomas). All of these tumors were benign and trisomy 12 was observed in all cases. Moreover, 3 cases presented trisomy and tetrasomy for chromosome 12 simultaneously. The high frequency of trisomy 12 in this tumor type suggests that this abnormality might be implicated in ovarian tumorigenesis.

Abstract
Langerhans' cell histiocytosis (LCH) may be associated with a wide range of neoplastic disorders. However, the combination of a LCH and a basal cell carcinoma (BCC) of the skin still represents a highly unusual condition. In this publication, we report the case of a 48-year-old woman who developed a localized LCH involving the area of a previously excised BCC. Although the exact pathogenesis of this peculiar association remains yet to be elucidated, the hypothesis of an exaggerated Langerhans' cell reaction in response to the underlying BCC appears to be attractive.
