BACKGROUND: Squamous cell carcinoma of the head and neck (HNSCC) represents an array of disease processes with a generally unfavorable prognosis. Inflammation plays an important role in tumor development and response to therapy. We performed a retrospective analysis of HNSCC patients to explore the relationship of the lymphocyte and neutrophil counts, the neutrophil-to-lymphocyte ratio (NLR) overall survival (OS), cancer-specific survival (CSS), local control (LC) and distant control (DC)...

BACKGROUD: Laryngeal preservation is an important consideration when treating cervical esophageal cancers (CECs) such as laryngeal cancer. The standard treatment for CEC allowing laryngeal preservation is chemoradiotherapy. However, in cases of laryngeal cancer, chemoselection has also been applied as a treatment strategy that promotes larynx preservation. This strategy involves assigning the appropriate radical treatment according to the primary tumor's response to induction chemotherapy...

INTRODUCTION: Actinomycosis of the larynx has been rarely reported in the literature and usually occurs in patients with a history of laryngeal carcinoma and radiation therapy. However, its co-existence with chondroradionecrosis due to radiotherapy is even rarer. The most common site of infection is the cervicofacial region, especially in the submandibular area. CASE REPORT: Here we report a 63-year-old male with a history of chemoradiotherapy because of laryngeal cancer 1 year earlier who presented with laryngeal actinomycosis...

Carcinosarcoma or sarcomatoid carcinoma is a highly malignant variant of squamous cell carcinoma, which comprises 2 to 3 % of all laryngeal cancer. It is considered to be a biphasic tumour, composed of a squamous cell carcinoma (in situ or invasive) and spindle cell carcinoma with sarcomatous appearance. We present a case of huge carcinosarcoma of larynx in a 34 year-old male who developed severe stridor and dysphagia. The diagnosis was confirmed histopathologically, hence the disease was treated through total laryngectomy followed by adjuvant chemotherapy and radiotherapy...

Radiotherapy (RT) is often the first choice of treatment for cancer of the larynx. Studies have shown that the incidence of carotid stenosis (CS) after radiotherapy of laryngeal cancer is increasing, and that gender difference in radiotherapy-induced side effects exist. Thus, we examined the gender difference in the incidence of CS and the impact of microinflammatory factors after radiotherapy. We reported this study on patients who received radiotherapy as part of the treatment for laryngeal cancer in the Jilin Province in China...
