BACKGROUND During the last 20 years, survival rates of head and neck carcinoma patients in the United States and Europe have plateaued. To determine the factors that can reduce mortality rates, we examined changes in clinical presentation and survival rates across 24 years of treatment of head and neck carcinoma patients. METHODS A retrospective study of(More)
A series of squamous cell carcinomas (SCC) of the hypopharynx treated with combined surgery and radiotherapy is presented to highlight the results of treatment at an early stage of disease. A retrospective mono-institutional analysis was performed on 153 previously untreated patients with SCC of the hypopharynx, seen between 1980 and 1995 at our(More)
BACKGROUND Radiotherapy (RT) has a remarkable success rate in the treatment of patients with glottic carcinoma. The objectives of the current study were to assess the results in a group of consecutive patients with comparable characteristics who were treated with RT (6-megavolt photon linear accelerator) and to determine the prognostic factors that may(More)
The sentinel node, which is not always located at the first-echelon nodal area close to the primary tumor, is the initial recipient of possible metastasis. In order to verify the usefulness of the sentinel lymph node technique in the staging of head and neck cancers, we studied 31 untreated patients with squamous cell carcinoma of the upper airways by(More)
PURPOSE At least in some European Countries, there is still considerable controversy regarding the choice between surgery and radiotherapy for the treatment of patients with early laryngeal-glottic carcinoma. METHODS AND MATERIALS Two hundred and forty-six patients with laryngeal-glottic neoplasms, Stage I-II, were treated with radical radiotherapy.(More)
This study presents the immunophenotypic and functional analysis of lymphocyte subsets obtained from peripheral blood and lymphoid tissue from HIV+ individuals treated with highly active anti-retroviral therapy (HAART) alone or in combination with 6 million units international (MUI) s.c. IL-2. Before treatment, the HIV+ patients had reduced CD4 and(More)
Sentinel node (SN) biopsy of head and neck cancer is still considered investigational, and agreement on the width of the surgical sampling has not yet been reached. From May 1999 to Dec 2009, 209 consecutive patients entered a prospective study: 61.7% had primary tumour of the oral cavity and 23.9% of the oropharynx. SN was not found in 26 patients. Based(More)
Most studies concerning the use of the sentinel node technique in head and neck cancers have included clinically N0 patients with primary early stage tumours of the oral cavity or upper part of oropharynx; furthermore, node sampling has been performed during the same session, but separately from the tumour. The perspective of avoiding unnecessary neck(More)
An efficent antitumor and antiviral cellular immune response requires optimal interferon-γ (IFN-γ) secretion and perforin expression in CD8+ T cells. The aim of this study was to define whether CD4+ and CD8+ T cells from patients with undifferentiated carcinoma of nasopharyngeal type (UCNT), a tumor regularly associated with the Epstein-Barr virus (EBV),(More)
OBJECTIVE In the staging of lung cancer, pleural effusion that is malignant on cytologic examination is regarded as T4 disease, and curative resection cannot be performed. We conducted this study to determine whether cancer cells can be present in the pleural cavity with no pleural effusion, to investigate the factors contributing to that occurrence, and to(More)
