New-Generation Heterocyclic Bis-Pentamethinium Salts as Potential Cytostatic Drugs with Dual IL-6R and Mitochondria-Targeting Activity.

IL-6 signaling is involved in the pathogenesis of a number of serious diseases, including chronic inflammation and cancer. Targeting of IL-6 receptor (IL-6R) by small molecules is therefore an intensively studied strategy in cancer treatment. We describe the design, synthesis, and characteristics of two new bis-pentamethinium salts and (meta and para) bearing indole moieties.

IDH Mutation Analysis in Glioma Patients by CADMA Compared with SNaPshot Assay and two Immunohistochemical Methods.

Mutations in IDH1/2 genes are a marker of good prognosis for glioma patients, associated with low grade gliomas and secondary glioblastomas. Immunohistochemistry and Sanger sequencing are current standards for IDH1/2 genotyping while many other methods exist. The aim of this study was to validate Competitive amplification of differentially melting amplicons (CADMA) PCR for IDH genotyping by comparison with SNaPshot assay and two immunohistochemical methods.

[A Patient with Primary Intraventricular Gliosarcoma and Long-term Survival - a Case Report].

Background: Gliosarcoma is a rare, malignant CNS tumor with a very poor prognosis. Gliosarcoma is a variant of glioblastoma multiforme, which is characterized by the presence of both glial and mesenchymal components. The treatment strategy for gliosarcomas has not yet been determined clearly.

[Multimodal Therapy of Recurrent Malignant Schwannoma].

Background: Malignant peripheral nerve sheath tumor schwannoma (MPNST), also known as malignant schwannoma, is a very rare tumor accounting for only 2% of all sarcomas. The prognosis is relatively poor, with a 5-year survival rate of 46-69%. The treatment of MPNST has not been standardized yet.

Glioblastoma multiforme in patients with history of extracranial cancer: Case series.

Objectives: Significant progress in treatment strategies improves the expectations of patients with extracranial cancers. Metastases are the primary consideration in patients with cancer history. In the case of neurologic disorders, the patient should undergo brain MRI.

Triple negative breast cancer - BCL2 in prognosis and prediction. Review.

Background: Breast cancer (BC), the most frequent malignancy in women worldwide, is currently diagnosed in about 1.4 million female patients annually. Approximately 10-20% of BC is represented by triple negative breast cancer (TNBC) which is aggressive, the prognosis is poor and patients cannot benefit from targeted treatment based on hormonal or HER2 receptors.

Isocitrate dehydrogenase 1 and 2 mutations in gliomas.

Over the past few years, new biomarkers have allowed a deeper insight into gliomagenesis and facilitated the identification of possible targets for glioma therapy. Isocitrate dehydrogenase (IDH) 1 and IDH2 mutations have been shown to be promising biomarkers for monitoring disease prognosis and predicting the response to treatment. This review summarizes recent findings in this field.

An adult multifocal medulloblastoma with diffuse acute postoperative cerebellar swelling: immunohistochemical and molecular genetics analysis.

Medulloblastoma (MB), the most common malignant tumor typically affecting children, occurs only exceptionally in adults. Multifocal presentation of this malignancy in adulthood is even much rarer—only four cases with favorable postoperative course have been reported, so far. The study illustrates a very rare rapid postoperative clinical deterioration due to diffuse cerebellar swelling (DCS) in an adult multifocal MB (MMB).
