Few evidence-based guidelines are available for the treatment of adult medulloblastoma, an extremely rare disease. Therapeutic regimens, typically modeled following pediatric protocols, consist of surgical resection followed by radiotherapy with or without adjuvant chemotherapy. Because of the rarity of this disease in adults, any treatment undertaken is based mainly on small and retrospective studies. Unlike pediatric patients, adults with medulloblastoma have been treated according to risk-adapted therapeutic strategies in only a few prospective studies. Overall, approximately 30% of patients experience recurrence and die of disease-related causes. Although the patients could respond to second-line treatments, the prognosis of patients with recurrence remains dismal. An important challenge for the future will be the biologic characterization of medulloblastoma in adults, with the identification of specific genetic patterns of patients with different prognosis and different response to targeted treatments.

Immunotherapy is a promising area of therapy in patients with neuro-oncological malignancies. However, early-phase studies show unique challenges associated with the assessment of radiological changes in response to immunotherapy reflecting delayed responses or therapy-induced inflammation. Clinical benefit, including long-term survival and tumour regression, can still occur after initial disease progression or after the appearance of new lesions. Refinement of the response assessment criteria for patients with neuro-oncological malignancies undergoing immunotherapy is therefore warranted. Herein, a multinational and multidisciplinary panel of neuro-oncology immunotherapy experts describe immunotherapy Response Assessment for Neuro-Oncology (iRANO) criteria based on guidance for the determination of tumour progression outlined by the immune-related response criteria and the RANO working group. Among patients who demonstrate imaging findings meeting RANO criteria for progressive disease within 6 months of initiating immunotherapy, including the development of new lesions, confirmation of radiographic progression on follow-up imaging is recommended provided that the patient is not significantly worse clinically. The proposed criteria also include guidelines for the use of corticosteroids. We review the role of advanced imaging techniques and the role of measurement of clinical benefit endpoints including neurological and immunological functions. The iRANO guidelines put forth in this Review will evolve successively to improve their usefulness as further experience from immunotherapy trials in neuro-oncology accumulate. © 2015 Elsevier Ltd.

Pancreatic tumours are usually very aggressive cancer with a poor prognosis. A limitation of pancreatic imaging techniques is that lesions are often of ambiguous relevance. The inability to achieve a definitive diagnosis based on cytological evaluation of specimens, due to sampling error, paucicellular samples or coexisting inflammation, might lead to delay in clinical management. Given the morbidity associated with pancreatectomy, a proper selection of patients for surgery is fundamental. Many studies have been conducted in order to identify specific markers that could support the early diagnosis of pancreatic lesions, but, to date, none of them allow to diagnose pancreatic cancer with high sensitivity and specificity. MicroRNAs (miRNA) are small non-coding RNAs (19-25 nucleotides) that regulate gene expression interacting with mRNA targets. It is now established that each tissue shows a characteristic miRNA expression pattern that could be modified in association with a number of different diseases including neoplasia. Due to their key role in the regulation of gene expression, in the last years several studies have investigated miRNA tissue-specific expression, quantification and functional analysis to understand their peculiar involvement in cellular processes. The aim of this review is to focus on miRNA expression in pancreatic cancer and their putative role in early characterisation of pancreatic lesions. Source

The role of temozolomide concurrent with and adjuvant to radiotherapy (RT/TMZ) in elderly patients with glioblastoma (GBM) remains unclear. We evaluated the outcome of patients >70 years in the context of the Project of Emilia-Romagna Region in Neuro-Oncology (PERNO), the first Italian prospective observational population-based study in neuro-oncology. For this analysis the criteria for selecting patients enrolled in the PERNO study were: age >70 years; PS 0–3; histologically confirmed GBM; postoperative radiotherapy (RT) after surgery with or without concomitant temozolomide (TMZ) or postsurgical TMZ alone. Between January 2009 and December 2010, 76 GBM elderly patients were identified in the prospective PERNO study. Twenty-three patients did not receive any treatment after surgery, and 53 patients received postsurgical treatments (25 patients received RT alone and 28 patients RT/TMZ). Median survival was 11.1 months (95 % CI 8.8–13.5), adding temozolomide concomitant and adjuvant to radiotherapy it was 11.6 months (95 % CI 8.6–14.6), and 9.3 months (95 % CI 8.1–10.6) in patients treated with RT alone (P = 0.164). However, patients with MGMT methylated treated with RT/TMZ obtained a better survival (17.2 months, 95 % CI 11.5–22.9) (P = 0.042). No difference in terms of survival were observed if patients with MGMT unmethylated tumor received RT alone, or RT/TMZ or, in MGMT methylated tumor, if patients received radiotherapy alone. In elderly patients RT/TMZ represent a widely used approach but it is effective with methylated MGMT tumors only. © 2016 Springer Science+Business Media New York Source

Background: Treatment options for glioblastoma (GBM) at recurrence have limited efficacy. Re-surgery has been used for confirmation of recurrent disease and to provide relief of symptoms but the real impact on survival is unknown. Patients and Methods: A retrospective analysis was performed for GBM patients followed between 01/2005 and 06/2010 at our Institution. Results: Two hundred and thirtytwo patients with recurrent GBM were evaluated. One hundred and two patients (44%) were treated with re-surgery followed by chemotherapy and 130 patients (56%) with chemotherapy alone. In multivariate analysis, no significant effect of re-surgery was found, with age (p=0.001), MGMT methylation (p=0.002) and PFS at 6 months (p=0.0001) being significant prognostic factors. Conclusion: Second surgery might have a limited impact in the clinical course of recurrent GBM patients. Source
