- Background: The malignant brain tumour glioblastoma is a devastating disease that remains a therapeutic challenge. Materials and Methods: Effects of combinations of the US Food and Drug Administation (FDA) approved proteasome inhibitor bortezomib and the histone deacetylase (HDAC) inhibitors vorinostat, valproic acid and sodium phenylbutyrate were studied on primary glioblastoma stem cell lines and conventional glioblastoma cell lines. Cell survival, proliferation and death were analyzed by fluorometric microculture cytotoxicity assay (FMCA), propidium iodide labeling and flow cytometry, and cell cloning through limiting dilution and live-cell bright-field microscopy. Results: Bortezomib and the HDAC inhibitors showed synergistic cell killing at clinically relevant drug concentrations, while the conventional cell lines cultured in serum-containing medium were relatively resistant to the same treatments. Conclusion: These findings of synergistic glioblastoma stem cell killing by bortezomib and three different FDA-approved HDAC inhibitors confirm and expand previous observations on co-operative effects between these classes of drugs.

- AIM: The aim of the present study was to retrospectively investigate the impact of induction chemotherapy on treatment outcome in patients treated with curatively intended radiotherapy for non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients with a diagnosed NSCLC that have been subjected to curatively intended irradiation (≥50 Gy) and treated in an oncology department in Sweden during the years 1990-2000 were included in the study. Operated patients and patients having received concomitant chemotherapy were excluded. The included patients were localised by a manual search of all the oncology departments' medical records and radiation charts. RESULTS: Patients treated with induction chemotherapy (n=79) had a significantly better overall survival compared with patients treated with radiotherapy alone (p=0.0097) in a univariate Cox regression analysis. A platinum/taxane combination produced the greatest survival benefit; hazard ratio=0.49 (95% confidence interval=0.31 to 0.75). CONCLUSION: We found that patients treated with induction chemotherapy in addition to radiotherapy for NSCLC have a better overall survival than patients treated with radiotherapy alone and that the best results are achieved using a platinum/taxane combination.

Forskningsöversikt (refereegranskat)abstract
- Treatment of patients with glioblastoma improved dramatically when concomitant and adjuvant temozolomide was added to external radiation therapy. The addition of this new treatment schedule as well as the improvements in individually-tailored radiation treatment, has resulted in a larger proportion of patients being fit for further treatment after first relapse. One of the most interesting combinations that have started to become part of the therapeutic arsenal in the daily clinic is dose-dense temozolomide in combination with bevacizumab. We reviewed and compiled the literature concerning the present topic based on a search of the PubMed database (http://www.ncbi.nlm.nih.gov/pubmed/) for the years between 1995 and 2011. The clinical studies that have been performed are small and divergent, making it difficult to grade the scientific evidence for the combinatorial treatment of dose-dense temozolomide and bevacizumab. However, the available studies and the experience we have at our departments suggest that this combination is of interest for glioblastoma patients experiencing first relapse. More randomized clinical trials are needed in order to establish the standard of treatment at first relapse in patients with glioblastoma.
