p>This review aims to emphasize new insights into the diagnosis, classification, and therapy of bladder cancer (BC). Bladder cancer is a heterogeneous, complex disease on a morphological, molecular, diagnostic, and prognostic level. Cancer stage is still the most important attribute for prognosis and treatment, while early detection with optimal an...

Background Hypofractionated post-prostatectomy radiotherapy is emerging practice, however with no randomized evidence so far to support it’s use. Additionally, patients with persistent PSA after prostatectomy may have aggressive disease and respond less well on standard salvage treatment. Herein we report outcomes for conventionally fractionated (C...

Prostate cancer (PCa) is the most commonly diagnosed neoplasm among men. Since it often resembles benign prostate hyperplasia (BPH), biomarkers with a higher differential value than PSA are required. Epigenetic biomarkers in liquid biopsies, especially miRNA, could address this challenge. The absolute expression of miR-375-3p, miR-182-5p, miR-21-5p...

Testicular germ cell tumors (TGCTs) are ever more affecting the young male population. Germ cell neoplasia in situ (GCNIS) is the origin of TGCTs, namely, seminomas (SE) and a heterogeneous group of nonseminomas (NS) comprising embryonal carcinoma, teratoma, yolk sac tumor, and choriocarcinoma. Response to the treatment and prognosis, especially of...

Neuroendocrine breast cancer (NEBC) is a group of rare tumors, which could benefit from therapy targeting the somatostatin receptors (SSTRs). In particular, SSTR2A and SSTR5 are potential targets given their consistent expression in gastrointestinal and pancreatic primary and metastatic neuroendocrine cancers. Currently, there are no studies descri...

Benign and malignant tumors are common in the setting of neurofibromatosis type 1 (NF1). Malignant peripheral nerve sheath tumor (MPNST) and angiosarcoma are rare tumors in children and adolescents and mostly occur in young patients in relation to NF1. Both histological types can be present in the same tumor mass in patients with NF1. We present a...

Chronic inflammation is associated with both benign conditions and cancer. Likewise, inflammatory cells are quite common in benign prostatic hyperplasia (BPH) and prostatic tissue harboring cancer. Triggers that activate inflammatory pathways in the prostate remain a subject of argument and are likely to be multifactorial, some of these being bacte...

Myelolipoma is a rare, benign, non-functioning tumor most frequently located in the adrenal cortex. It consists of mature fatty tissue with components of hematopoietic tissue in different proportions. There are certain ambiguities related to the diagnosis and therapy of myelolipoma, and it is therefore important to keep in view all the aspects of t...
