Survival analysis after stereotactic ablative radiotherapy for early stage non-small cell lung cancer: a single-institution cohort study.

Background: Stereotactic ablative radiotherapy (SABR) is the standard treatment for medically inoperable early-stage non-small cell lung cancer (ES-NSCLC), but which patients benefit from stereotactic radiotherapy is unclear. The aim of this study was to analyze prognostic factors for early mortality.

Methods: From August 2010 to 2022, 617 patients with medically inoperable, peripheral or central ES-NSCLC were treated with SABR at our institution.

Targeting genotoxic and proteotoxic stress-response pathways in human prostate cancer by clinically available PARP inhibitors, vorinostat and disulfiram.

Background: Castration-resistant prostate cancer (PCa) represents a serious health challenge. Based on mechanistically-supported rationale we explored new therapeutic options based on clinically available drugs with anticancer effects, including inhibitors of PARP1 enzyme (PARPi), and histone deacetylases (vorinostat), respectively, and disulfiram (DSF, known as alcohol-abuse drug Antabuse) and its copper-chelating metabolite CuET that inhibit protein turnover.

Methods: Drugs and their combination with ionizing radiation (IR) were tested in various cytotoxicity assays in three human PCa cell lines including radio-resistant stem-cell like derived cells.

Risks and protective factors for triple negative breast cancer with a focus on micronutrients and infections.

Triple negative breast cancer (TNBC) is an aggressive form of breast cancer (BC) with a poor prognosis. Second, patients cannot benefit from targeted therapy, except for those with BRCA1/2 mutations, for whom poly (ADP-ribose) polymerase (PARP) inhibition therapy using olaparib has recently been approved. As global priorities continue to be epidemiological analysis of BC risk factors and early diagnosis, this review focuses on the risks and protective factors associated with TNBC.

[Radiotherapy of Lung Tumours in Idiopathic Pulmonary Fibrosis].

Background: This article is a joint statement of the Czech Pneumological and Physiological Society and the Czech Society for Radiation Oncology, Biology and Physics, and reviews current opinions on radiotherapy in patients with idiopathic pulmonary fibrosis (IPF). In general, radiotherapy of lung tumours is associated with risk of radiation pneumonitis (RP); moreover, IPF may be complicated by acute exacerbations (AE-IPF). Both complications may immediately threaten patients lives.

[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.
