Background And Objective: The aim of this study was to investigate the diagnostic accuracy of ultrasound guided fine needle aspiration cytology (FNAC) and core needle biopsy (CNB) in different clinical scenarios for melanoma patients with lesions suspected of metastasis.
Methods: We included all patients at our department attending follow-up after surgery for cutaneous melanoma, who had undergone either FNAC or CNB between December 2016 and June 2019. Biopsy results were classified into one of four categories and verified with follow-up including imaging, re-biopsy or histology upon excision.
Uveal melanoma (UM) is the most common intraocular malignancy in adults and shows a high rate of metastatic spread. As randomized clinical trials with immune checkpoint inhibitors (ICI) have not been performed in patients with metastatic UM, we analyzed the real-world outcomes in a nationwide population-based study. Clinical data of patients with UM were extracted from the Danish Metastatic Melanoma database, a nationwide database containing unselected records of patients diagnosed with metastatic melanoma in Denmark.

To characterize resistance mechanisms, we have generated different tamoxifen-resistant breast cancer cell lines from MCF-7. In this model, we investigated whether signaling from human epidermal growth factor receptors (HERs), their downstream kinases, or from the estrogen receptor α (ERα) was driving tamoxifen-resistant cell growth.

We evaluated TIMP-1 as a prognostic marker in patients treated with adjuvant tamoxifen and investigated TIMP-1s association with Ki67 and ER/progesterone receptor (PR)/human epidermal growth factor receptor 2 (HER2) profiles.
Material And Methods: TIMP-1 expression was evaluated by immunohistochemistry (IHC) on formalin fixed paraffin embedded primary tumor tissue in two independent cohorts comprised of 236 and 192 patients, respectively.
Antiestrogen resistance is a major clinical problem in current breast cancer treatment. Therefore, biomarkers and new treatment options for antiestrogen-resistant breast cancer are needed. In this study, we investigated whether antiestrogen‑resistant breast cancer cell lines have increased sensitivity to carboplatin, as it was previously shown with cisplatin, and whether low Bcl-2 expression levels have a potential value as marker for increased carboplatin sensitivity.

The receptors form dimers, leading to activation by mutual phosphorylation. Our purpose was to explore the role of the activated receptors (pHER1, pHER2, pHER3) in endocrine treated breast cancer in terms of co-expression and association with disease-free survival (DFS) in 1062 patients with ER-positive tumors.

Bcl-2 is regulated by ER and may thus be considered as an indicator of ER activity and a candidate supplementary marker to ER status.
Patients And Methods: Tumor tissue from 257 patients with ER-positive breast cancer treated with tamoxifen was used for determination of the best threshold for immunohistochemical Bcl-2 assessment as prognostic marker.
Objectives: To evaluate a simple method for counting mast cells, thought to have a role in the pathophysiology of bladder pain syndrome (BPS, formerly interstitial cystitis, a syndrome of pelvic pain perceived to be related to the urinary bladder and accompanied by other urinary symptoms, e.g. frequency and nocturia), as >28 mast cells/mm(2) is defined as mastocytosis and correlated with clinical outcome.

Until recently the only possible treatment was supportive care with transfusions and antibiotics, but new options have now become available. In this article the results of immunosuppressive treatment are described and discussed.
