INTRODUCTION Cutaneous eccrine porocarcinomas are uncommon malignant tumors of the sweat gland. CASE PRESENTATION A 76-year-old Caucasian man presented to our hospital with a left temporal mass. We describe a case of eccrine porocarcinoma with metastasis to the parotid gland with special emphasis on the role of surgical resection and adjuvant radiation(More)
PURPOSE The combination of cisplatin and radiotherapy is a standard treatment for patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN). Cetuximab-radiotherapy is superior to radiotherapy alone in this population, validating epidermal growth factor receptor (EGFR) as a target. Erlotinib is a small-molecule inhibitor of EGFR.(More)
IMPORTANCE Approximately 50% of head and neck cancer survivors experience dysphagia and related morbidity. Intensity-modulated radiation therapy (IMRT) is increasingly used to treat oropharyngeal cancers with excellent oncologic outcomes, but few studies have compared it with conventional 3-dimensional conformal radiation therapy (3D-CRT) to determine(More)
Treatment and cure of salivary gland neoplasms requires surgical intervention in most cases. For parotid neoplasms, the most common surgical procedure performed is the superficial parotidectomy with facial nerve preservation. Postoperative radiation therapy is indicated in high-grade salivary gland malignancies and malignancies with increased risk of(More)
Thyroid cancer is an uncommon tumor accounting for roughly 1% of all new malignancies. Differentiated (ie, papillary or follicular) thyroid carcinoma is usually asymptomatic, and frequently appears as a solitary thyroid nodule but few show cervical lymphadenopathy or metastasis to lung, bone, or liver. Fine needle aspiration (FNA) is recommended in the(More)
AIMS S-nitrosylation and S-glutathionylation, redox-based modifications of protein thiols, are recently emerging as important signaling mechanisms. In this study, we assessed S-nitrosylation-based regulation of Janus-activated kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) pathway that plays critical roles in immune/inflammatory(More)
Malignancies of the nasal cavity and paranasal sinuses represent a wide spectrum of histologies, tissues of origin, and anatomic primary sites. The inherent difficulty in generalizing treatment approaches is obvious, given the numerous variables associated with the broadly-based term, paranasal sinus malignancy (PNSCa). Nevertheless, the majority of(More)
OBJECTIVE To investigate the association between initial body mass index (BMI) and chemoradiation therapy (CRT) outcomes in head and neck cancer patients. METHODS Retrospective study of 72 patients with American Joint Committee on Cancer stage III or IV squamous cell carcinoma of the oropharynx, hypopharynx, or larynx treated with primary concurrent CRT(More)
Oral cancer is the sixth most common cancer in the world, and it continues to represent a serious public health problem. Oral cancer is a preventable disease, related to behavioral and lifestyle factors, including tobacco and alcohol. Prevention and early detection of oral cancer remain the goals of national efforts to reduce the impact of this disease on(More)
