Advanced carcinoma of the oropharynx: survival analysis comparing two treatment modalities.

About 92,000 new cases of oropharynx carcinoma are expected to occur annually worldwide. There is no consensus about the best therapy for these advanced tumors. The objective of the present study was to evaluate overall and disease-free survival rates of patients with advanced oropharynx squamous cell carcinoma, comparing surgery + radiotherapy with chemotherapy + radiotherapy.

Immunophenotype of neutrophils in oral squamous cell carcinoma patients.

Background: The aim was to explore the immunophenotype of neutrophils and lymphocytes and the inflammatory mediators in patients with oral squamous cell carcinoma, comparing with controls; and to associate with clinicopathological data.

Methods: Blood was collected from 13 patients and 13 controls. The immunophenotype of neutrophils (CD66b, CD16, CD11a, arginase-1), T lymphocytes (CD4, CD8) and the intracellular cytokine production (IL-10, TNF, IFN-γ) was evaluated by flow cytometry.

Differential infiltration of neutrophils in T1-T2 versus T3-T4 oral squamous cell carcinomas: a preliminary study.

Background: Recent studies have pointed towards a role of tumour-infiltrating neutrophils in cancer biology. Investigations on oral squamous cell carcinoma have indicated a possible association with clinical characteristics. This study aimed to evaluate neutrophil infiltration and the neutrophil/lymphocyte ratio in the central areas and invasive front of oral squamous cell carcinomas at different T stages, and their association with clinicopathological features and patient outcome.
