Palmar metastasis of an adenocarcinoma of the esophago-gastric-junction: First case report.

INTRODUCTION: Hand metastasis represents only approximately 0.007-0.2% of all metastatic lesions. The most common origin of hand metastasis is the lung, which is approximately 50% of all cases, followed by breast and kidney. Hand metastasis from gastric or esophagic cancer is even much more rare. PRESENTATION OF CASE: This is the first case report of a metastasis to the palm of hand (tendon) due to an adenocarcinoma of esophago-gastric-junction. DISCUSSION: While most of the esophagic and gastric carcinomas metastasizes to liver, lungs and brain, the rare possibility of encountering metastasis to the hand either to the bone, but also to the tendon exists. Therefore, we recommend obtaining a thorough history and a detailed clinical examination, plain radiographs, followed by axial imaging techniques like MRI and a histopathologic evaluation. CONCLUSION: Even if metastatic lesions to the hand are really rare, the surgeon should always be suspicious of a metastatic lesion, when presented with a patient older than 40 years who has a history of cancer.

Low p27 expression predicts early relapse and death in postmenopausal hormone receptor-positive breast cancer patients receiving adjuvant tamoxifen therapy.

PURPOSE: Previously, we have shown that p27 may be a potential predictive biomarker for the selection of premenopausal women with early-stage hormone-responsive breast cancer for adjuvant endocrine therapy. The purpose of the present study was to assess the clinical relevance of p27 expression in postmenopausal hormone receptor-positive breast cancer patients who were treated with adjuvant tamoxifen therapy. EXPERIMENTAL DESIGN: We determined the expression of p27 by immunohistochemistry in the surgical specimens of breast carcinoma patients who had been enrolled in Austrian Breast and Colorectal Cancer Study Group Trial 06 and received tamoxifen for 5 years. Early relapse and death within the first 5 years of follow-up were analyzed using Cox models adjusted for clinical and pathologic factors. RESULTS: p27 expression was high (>70% p27-positive tumor cells) in 252 of 483 (52%) tumor specimens and was associated with favorable outcome of the patients. Women with high p27 expression had a significantly longer disease-free survival (adjusted hazard ratio for relapse, 0.22; 95% confidence interval, 0.11-0.42; P < 0.001) and overall survival (adjusted hazard ratio for death, 0.39; 95% confidence interval, 0.21-0.72; P = 0.002) as compared with women with low p27 expression. CONCLUSION: Low p27 expression independently predicts early relapse and death in postmenopausal women with early-stage, hormone receptor-positive breast cancer who received adjuvant tamoxifen for 5 years.

The Austrian Brain Tumour Registry: a cooperative way to establish a population-based brain tumour registry.

In Austria, registration of malignant brain tumours is legally mandatory, whereas benign and borderline tumours are not reported. The Austrian Brain Tumour Registry (ABTR) was initiated under the auspices of the Austrian Society of Neuropathology for the registration of malignant and non-malignant brain tumours. All Austrian neuropathology units involved in brain tumour diagnostics contribute data on primary brain tumours. Non-microscopically verified cases are added by the Austrian National Cancer Registry to ensure a population-based dataset. In 2005, we registered a total of 1,688 newly diagnosed primary brain tumours in a population of 8.2 million inhabitants with an overall age-adjusted incidence rate of 18.1/100,000 person-years. Non-malignant cases constituted 866 cases (51.3%). The incidence rate was higher in females (18.6/100,000) as compared to males (17.8/100,000), while 95/1,688 (5.6%) cases were diagnosed in children (<18 years). The most common histology was meningioma (n = 504, 29.9%) followed by glioblastoma (n = 340, 20.1%) and pituitary adenoma (n = 151, 8.9%). Comparison with the Central Brain Tumor Registry of the United States (CBTRUS) database showed high congruency of findings. The ABTR model led by neuropathologists in collaboration with epidemiologists and the Austrian National Cancer Registry presents a cooperative way to establish a population-based brain tumour registry with high quality data. This setting links cancer registration to the mission of medical practice and research as defined by the World Medical Association in the Declaration of Helsinki. The continued operation of ABTR will aid in monitoring changes in incidence and in identifying regional disease clusters or geographic variations in brain tumour morbidity/mortality.

Cyclin D1 expression in breast cancer patients receiving adjuvant tamoxifen-based therapy.

PURPOSE: The objective of our study was to determine the clinical relevance of cyclin D1 expression in hormone receptor-positive breast cancer patients who were treated with tamoxifen-based therapy. EXPERIMENTAL DESIGN: We assessed expression of cyclin D1 in surgical specimens of breast carcinoma by means of immunohistochemistry. Patients had been enrolled in either Austrian Breast and Colorectal Cancer Study Group (ABCSG) Trial 05 or ABCSG Trial 06 and received tamoxifen as part of their adjuvant treatment. Overall survival and relapse-free survival were analyzed with Cox models adjusted for clinical and pathologic factors. RESULTS: Cyclin D1 was expressed in 140 of 253 (55%) tumors of ABCSG Trial 05 and in 569 of 948 (60%) tumors of ABCSG Trial 06. Expression of cyclin D1 was associated with poor outcome in both cohorts. Overall survival was significantly shorter in patients with cyclin D1-positive tumors compared with patients with cyclin D1-negative tumors [adjusted hazard ratio (HR) for death (ABCSG Trial 05), 2.47; 95% confidence interval (95% CI), 1.08-5.63; P = 0.03; adjusted HR for death (ABCSG Trial 06), 1.78; 95% CI, 1.36-2.34; P < 0.0001]. Relapse-free survival was also shorter in patients with cyclin D1-positive tumors than in patients with cyclin D1-negative tumors [adjusted HR for relapse (ABCSG Trial 05), 2.73; 95% CI, 1.50-4.96; P = 0.001; adjusted HR for relapse (ABCSG Trial 06), 1.52; 95% CI, 1.14-2.04; P = 0.005]. CONCLUSION: Cyclin D1 expression is an independent poor prognostic factor in women with early-stage, hormone receptor-positive breast cancer who received adjuvant tamoxifen-based therapy.

Downregulation of TSLC1 and DAL-1 expression occurs frequently in breast cancer.

TSLC1 and DAL-1 are tumor suppressor genes involved in cell adhesion. In this study, we examined the expression and methylation pattern of these genes in breast cancer cell lines and primary breast carcinomas. TSLC1 expression was lost in 5 of 8 (63%) and DAL-1 expression was lost in 6 of 8 (75%) breast cancer cell lines, respectively. Downregulation of TSLC1 expression was observed in 43 of 50 (86%) and of DAL-1 expression in 26 of 55 (47%) primary breast carcinomas. TSLC1 methylation was found in 4 of 8 (50%) and DAL-1 methylation was observed in 6 of 8 (75%) breast cancer cell lines, respectively. Of 95 primary breast carcinomas 46 (48%) were TSLC1 methylated and 26 (27%) were DAL-1 methylated. Twenty of 43 (47%) and 10 of 26 (38%) primary breast cancer samples which showed downregulation of TSLC1 and DAL-1 expression were unmethylated for these genes. Re-expression of TSLC1 and DAL-1 was observed after treatment of BT-20 cells with 5-aza-2'-deoxycytidine and TSA. Samples from patients with grade 3 tumors were more frequently TSLC1 and TSLC1 and/or DAL-1 methylated than samples from patients with grade 1 and 2 tumors (P = 0.032, P = 0.023). Moreover, TSLC1 methylation correlated with loss of both ER and PgR staining (P = 0.011, P = 0.02). Our findings suggest that TSLC1 and DAL-1 are involved in the pathogenesis of breast cancer and are frequently inactivated by methylation.
