From chemotherapy to target therapies associated with radiation in the treatment of NSCLC: a durable marriage?

The integration between radiotherapy and drugs, from chemotherapy to recently available target therapies, continues to have a relevant role in the treatment of locally advanced and metastatic Non-small cell lung cancer (NSCLC). Aim of the present review is to evaluate the promising and emerging application of the best interaction between new drugs and new modalities of radiotherapy. Areas covered: We searched Medline, Google Scholar, PubMed, ProQuest Dissertation, and Theses databases for reports published in English.

p16 cutoff in head and neck squamous cell carcinoma: correlation between tumor and patient characteristics and outcome.

Background: p16 has been indicated as a suitable surrogate biomarker of HPV infection. The prognosis of p16-positive oropharynx tumors (OTs) of squamous cell carcinoma (SCC) histology is better than that of p16-negative tumors.

Methods: We analyzed 209 samples of head and neck SCC to establish a predictive cutoff for p16 and determine the role of p16 positivity in OTs versus non-OTs.

Treatment effect of buparlisib, cetuximab and irradiation in wild-type or PI3KCA-mutated head and neck cancer cell lines.

Introduction In complement to anti-EGFR therapy, the targeting of PI3K/AKT/mTOR signaling pathway is of particular interest in the management of Head and Neck Squamous Cell Carcinoma (HNSCC). Here, we assess the effects of PI3K inhibition combined with anti-EGFR monoclonal antibody cetuximab and/or irradiation (RT). Material and methods Anti-proliferative effects of the combination of buparlisib (a specific PI3K inhibitor), cetuximab and RT was determined in two HNSCC cell lines (CAL33, PI3KCA H1047R-mutated and CAL27, PI3KCA wild-type).

MGMT promoter methylation and glioblastoma: a comparison of analytical methods and of tumor specimens.

It is already well known that hypermethylation of the O6-methylguanine DNA methyltransferase (MGMT) gene promoter is a predictive biomarker of response to temozolomide treatment and of favorable outcomes in terms of overall survival (OS) and progression-free survival (PFS) in glioblastoma (GBM) patients. Nevertheless, MGMT methylation status has not currently been introduced into routine clinical practice, as the choice of the ideal technique and tissue sample specimen is still controversial. The aim of this study was to compare 2 analytical methods, methylation-specific polymerase chain reaction (MSP) and pyrosequencing (PSQ), and their use on 2 different tissue type samples, snap-frozen and formalin-fixed paraffin-embedded (FFPE), obtained from a single-center and uniformly treated cohort of 46 GBM patients.

Non coding RNAs in head and neck squamous cell carcinoma (HNSCC): a clinical perspective.

Background: Head and neck squamous cell carcinoma is a common cause of cancer death. Despite decades of clinical studies exploring new treatments and considerable advance in multimodality treatment, satisfactory curative rates have not yet been reached. In the last few decades the emerging data from both tumor biology and clinical trials led to growing interest for research of predictive biomarkers.
