Prospective trial of the Oncobox platform RNA sequencing bioinformatic analysis for personalized prescription of targeted drugs.

Interrogating gene expression in tumor can identify up- and downregulated molecular targets of cancer drugs. Here we report the results of prospective clinical investigation of using RNA sequencing analysis for personalized cancer therapy. Transcriptomic profiles were analyzed using Oncobox platform that identifies altered expression of drug target genes and molecular pathways and builds a personalized rating of targeted therapeutics.

Genomic Profiling in Glioma Patients to Explore Clinically Relevant Markers.

Gliomas are a heterogeneous group of brain tumors, among which the most aggressive subtype is glioblastoma, accounting for 60% of cases in adults. Available systemic treatment options are few and ineffective, so new approaches to therapies for glioblastoma are in high demand. In total, 131 patients with diffuse glioma were studied.

[Intrathecal chemotherapy for leptomeningeal metastases in patients with breast cancer].

Unlabelled: Leptomeningeal metastases are lesions of brain and/or spinal cord sheaths by tumor cells. They occur in 5% of patients with solid tumors, although autopsies reveal these lesions much more often (10-20% of cases). Leptomengeal metastases are an unfavorable prognostic factor.

Personalized targeted therapy prescription in colorectal cancer using algorithmic analysis of RNA sequencing data.

Background: Overall survival of advanced colorectal cancer (CRC) patients remains poor, and gene expression analysis could potentially complement detection of clinically relevant mutations to personalize CRC treatments.

Methods: We performed RNA sequencing of formalin-fixed, paraffin-embedded (FFPE) cancer tissue samples of 23 CRC patients and interpreted the data obtained using bioinformatic method Oncobox for expression-based rating of targeted therapeutics. Oncobox ranks cancer drugs according to the efficiency score calculated using target genes expression and molecular pathway activation data.

Real-World Experience with Targeted Therapy in BRAF Mutant Advanced Melanoma Patients: Results from a Multicenter Retrospective Observational Study Advanced Melanoma in Russia (Experience) (ADMIRE).

Clinical trials of targeted therapy (TT) and immunotherapy (IT) for highly aggressive advanced melanoma have shown marked improvements in response and survival rates. However, real-world data on treatment patterns and clinical outcomes for patients with advanced BRAF V600 mutant melanoma are ultimately scarce. The study was designed as an observational retrospective chart review study, which included 382 patients with advanced BRAF V600 mutant melanoma, who received TT in a real-world setting and were not involved in clinical trials.

A clinical case of combined treatment of a patient with breast cancer and metastases to the brain and meninges.

The article describes a clinical case of successful chemotherapeutic and radiation treatment of a patient with breast cancer and metastases to the brain and meninges and with a pronounced neurological deficit. The patient underwent combined treatment (whole brain radiation with TBD of 30 Gy and local radiation of a metastasis with TBD of 15 Gy associated with capecitabine therapy) with continued administration of capecitabine until improvement. A partial metastasis reduction by 50% and complete regression of the neurological deficit were observed.

[Complex treatment of breast cancer patients with brain metastases].

Brain metastases in breast cancer develop for 24-32 months after the detection of the primary tumor. The study included patients with brain metastases who were divided into three groups: the first group--with early chemoradiotherapy (CRT) without induction chemotherapy (IC) by capecitabine; the second group--with delayed CRT with 4 or 8 courses of IC by capecitabine; the third group (a historical control) who received only whole brain radiation therapy. The median time to progression of intracranial metastases was 15.

[Current possibilities of targeted therapy in the treatment of breast cancer with overexpression of HER-2/neu and metastatic lesions in the brain].

Targeted therapy (lapatinib and/or trastuzumab) in combination with chemotherapy (capecitabine) is highly effective in metastatic lesions of the brain in breast cancer patients with overexpress HER-2/neu. An objective response in the brain was achieved in 19 patients (55.9%).

[Combination chemotherapy with newly-developed cytostatics for disseminated small cell lung cancer].

The paper discusses the results of phase II clinical trials of chemotherapy regimens using newly-developed cytostatics for disseminated small cell lung cancer. Taxotere (docetaxel)/cisplatin and campto(irinotecan)/cisplatin were investigated as first-line treatment. Doxorubicin and vincristine in combinations with a novel antitumor cytostatic aranoza were studied for application as second-line treatment.
