PURPOSE To date, there is no screening test for lung cancer shown to affect overall mortality. MicroRNAs (miRNAs) are a class of small noncoding RNA genes found to be abnormally expressed in several types of cancer, suggesting a role in the pathogenesis of human cancer. PATIENTS AND METHODS We evaluated the circulating levels of tumor exosomes, exosomal(More)
BACKGROUND The relative efficacy of the addition of induction chemotherapy to chemoradiotherapy compared with chemoradiotherapy alone for patients with head and neck cancer is unclear. The PARADIGM study is a multicentre open-label phase 3 study comparing the use of docetaxel, cisplatin, and fluorouracil (TPF) induction chemotherapy followed by concurrent(More)
Head and neck squamous cell carcinoma (HNSCC) affects over half a million people worldwide. Despite advances in therapy, only half of the patients are alive in 5 years. Epidermal growth factor receptor (EGFR) is overexpressed in approximately 90% of the tumors, and it is correlated with poor response to treatment and worse outcome. Multiple therapies(More)
Merkel cell polyomavirus is the primary etiological agent of the aggressive skin cancer Merkel cell carcinoma (MCC). Recent studies have revealed that UV radiation is the primary mechanism for somatic mutagenesis in nonviral forms of MCC. Here, we analyze the whole transcriptomes and genomes of primary MCC tumors. Our study reveals that virus-associated(More)
A 55-year-old woman with GATA2 deficiency and neurofibromatosis 1 was diagnosed with Merkel cell carcinoma (MCC). This polyomavirus-associated cutaneous malignancy has previously been associated with immunosuppression and acquired immunodeficiencies such as HIV/AIDS. However, MCC has not been previously reported in the setting of underlying primary or(More)
AIMS To maximize the palliative benefits of capecitabine and oxaliplatin for patients with refractory squamous cell carcinoma of the head and neck (SCCHN). METHODS Patients received fixed-dose capecitabine (1500 mg orally twice a day) on days 1 to 7 and oxaliplatin (85 mg/m) days 1 and 14. RESULTS Fifteen patients with refractory SCCHN were enrolled.(More)
BACKGROUND Preclinical and clinical studies suggest potential synergy between high dose per fraction focal radiation and immunotherapy. However, conventionally fractionated radiation regimens in combination with concurrent chemotherapy are more commonly administered to patients as definitive treatment and may have both immune-stimulating and -suppressive(More)
BACKGROUND Although percutaneous endoscopic gastrostomy (PEG) is widely performed for nutrition or palliation, PEG-associated outcomes in cancer patients remain poorly described. We examined the safety and benefits of PEG placement in this population at our institution. STUDY DESIGN A 5-year retrospective review of patients with malignancy (excluding(More)
PURPOSE The clinical impact of next-generation sequencing (NGS) in patients with head and neck squamous cell carcinoma (HNSCC) has not been described. We aimed to evaluate the clinical impact of NGS in the routine care of patients with HNSCC and to correlate genomic alterations with clinical outcomes. EXPERIMENTAL DESIGN Single-center study examining(More)
