Serum, plasma and saliva biomarkers for head and neck cancer.
Serum, plasma and saliva biomarkers for head and neck cancer. Expert Rev Mol Diagn. 2017 Nov 14;: Authors: Arantes LMRB, de Carvalho AC, Melendez ME, Lopes Carvalho A Abstract INTRODUCTION: Head and neck squamous cell carcinoma (HNSCC) encompasses tumors arising from several locations (oral and nasal cavities, paranasal sinuses, salivary glands, pharynx, and larynx) and currently stands as the sixth most common cancer worldwide. The most important risk factors identified so far are tobacco and alcohol consumption, and, for a subgroup of HNSCCs, infection with high-risk types of human papillomavirus (HPV). Despite several improvements in the treatment of these tumors in the last decades, overall survival rates have only improved marginally, mainly due to the advanced clinical stage at diagnosis and the high rates of treatment failure associated with this late diagnosis. Areas covered: This review will focus on the feasibility of evaluating molecular-based biomarkers (mRNA, microRNA, lncRNA, DNA methylation and protein expression) in body fluids (serum, plasma, and saliva) as markers for diagnosis, prognosis, and surveillance. Expert commentary: The potential use of those markers in the clinical setting would allow for early diagnosis, prediction of treatment response, improvement in treatment selection and provide disease monitoring for early detection of tumor recurrence. It can ultimately be translated into better survival rates and improved quality of l...

CONCLUSION: Survival across the two time periods remained stable for oral SCC but showed a significant increase for oropharyngeal SCC, possibly because of improvements in the patients ’ response to radiotherapy, such as intensity-modulated radiation therapy, and the use of more accurate diagnostic imaging approaches.
ABSTRACT Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2015 its first recommendations about the management of HCC. Since then, new data have emerged in the literature, prompting the governing board of SBH to sponsor a single-topic meeting in August 2018 in S ão Paulo. All the invited experts were asked to make a systematic review of the literature reviewing the management of HCC in subjects with cirrhosis. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration o...
Goals: The main purpose of this study was to assess the recent trends in mortality and health care utilization of hepatocellular carcinoma (HCC) among Medicare population in the United States. Background: The incidence of HCC is increasing in the United States. Materials and Methods: Data were obtained for a sample of Medicare beneficiary from 2005 to 2014. Diagnosis of HCC and etiology of liver disease were based on ICD-9 codes. Temporal trends in HCC rates, clinical, demographical and utilization parameters were analyzed by joinpoint regression model. Results: Study cohort included 13,648 Medicare recipients w...
Conclusions: Prediagnosis use of metformin dose ≤1500 mg/d is associated with longer overall survival of elderly diabetic HCC patients.

Case Summary: A 69-year-old woman with a nonrelevant past medical history was referred to an outpatient colorectal clinic because of the incidental finding of an anal pigmented lesion during a routine gynecological examination. Anal inspection and proctoscopy indicated possible anal melanoma (Fig. 1A and B).
