The Role of microRNA in Head and Neck Cancer: Current Knowledge and Perspectives

Head and neck cancer is one of the most commonly diagnosed malignancies worldwide. Patients with advanced disease stages frequently develop recurrences or distant metastasis, which results a five-year survival rates of less than 60% despite considerable advances in multimodality therapy. A better understanding of molecular basis of tumorigenesis is required to improve clinical outcomes and to develop new anti-cancer drugs. microRNAs (miRNAs) are a class of small, non-coding, RNA molecules that modulate gene expression post-transcriptionally. They are important regulator in normal biological process; however miRNAs deregulation has been observed in many different tumors and is involved in tumorigenesis. miRNAs may act as tumor suppressors or as oncogenes. Several studies on head and neck cancer demonstrated how aberrant expression of miRNAs is involved in proliferation, metastasis, chemoresistence, and radioresistance. In addition, miRNAs are excellent biomarker targets because they circulate stable in human body fluids and can be obtained with non-invasive methods. Moreover, miRNAs up and down regulation has been correlated with specific cancer phenotype (poor prognosis, aggressiveness and resistance to treatment), playing a role as prognostic biomarkers. This review summarizes current finding on miRNAs in head and neck cancer and their potential role as target for next drug therapy

Multidisciplinary management of non small cell lung cancer (NSCLC) in stage III: clinical case description. Recommendations and state of the art

Lung cancer is the leading cause of cancer death in industrialized countries with progressive increase of its mortality rate. Non Small Cell Lung Cancer (NSCLC ) is approximately 80-85% of all lung cancers, being adenocarcinoma and squamous cell carcinoma the most common histologies. The majority of the patients with stage III clinical stage, presents a mediastinal lymph node involvement described with computed tomography (TC) and/or positron emission tomography (PET). The current approach to patients with NSCLC is multidisciplinary, especially for those staged as potentially operable, both for staging and for a correct definition of best treatment strategy. Updated international and national Guidelines and recommendations can provide valuable support to the clinician. The case described concerns the accidental detection of a tumour in the lung in a 58-year-old man with arterial hypertension controlled with ACE inhibitors. The treatments agreed after a multidisciplinary approach are cisplatin and docetaxel, the surgical resection, and the radiotherapy. After three months the patient has neither metastasis nor relapse

Safety and efficacy of abiraterone acetate (AA) in patients aged 75 or more with metastatic castration-resistant prostate cancer (mCRPC) in both pre-chemotherapy or post-chemotherapy settings: Real-life experience from thirteen Italian centers.

209 Background: Prostate cancer affects mainly elderly patients (pts) that have different comorbidities. AA is a selective androgen synthesis inhibitor that showed the efficacy in either chemotherapy (CT) naive pts or those pretreated with docetaxel. Its oral administration and good tolerability make it a manegeable treatment for elderly mCRPC pts. Methods: We collected retrospectively data regarding mCRPC pts aged ≥75 years treated with AA in 13 Italian Centers since April 2013. The median age was 79 years (r. 75-90) with 48% of pts being octagerians. Post CT pts had more extensive disease, higher baseline PSA and ECOG PS. Nearly all the pts had comorbidities, the most frequent being hypertension present in 146 pts (58%), 43 pts (17%) had diabetes type II. We evaluated duration of the AA treatment, overall response rate (ORR), 50% PSA decline, time to progression (TTP) and overall survival (OS). We reported all toxicities observed. Results: A total of 252 pts ,147 pre treated with docetaxel and 105 chemo naive, were included. Median duration of treatment with AA was 8,6 months in post CT and 11,5 in CT naive pts. ORR was 35,3% in pre docetaxel and 27,4% in post docetaxel group. 64 pts (65%) and 51 pts (46%) obtained 50% PSA reduction in pre and post docetaxel group, respectively. Median TTP was 8,6 in post docetaxel and 11,9 in CT naive pts. We observed a median OS of 13,8 months in post CT group while for CT naive pts data were not yet mature. AA was well tolerated with only 8 pts (3,2%) who discontinued treatment due to toxicity, while in 4 pts (1,6%) temporary dose reductions were performed. The most frequent G3 toxicities were hypertension and liver toxicity with 4 pts (1,6%) and 5 pts (2%), respectively. After progressing on AA, 85 pts (34%) received at least one subsequent treatment. 40 pts (15,9%) are still on treatment with AA. Conclusions: Even if almost all the pts reported comorbidities at AA start and 72 pts (28,6%) had PS ECOG 2, only a small proportion of them discontinued the treatment due to toxicity confirming that AA is well tolerated and efficient treatment also for elderly patients. </jats:p
