BACKGROUND In 1992, we reported the first analysis of a randomized trial comparing alternating radiotherapy and chemotherapy with radiotherapy alone in the treatment of squamous cell carcinoma of the head and neck. The results of that 3-year analysis indicated that the combined treatment had superior efficacy. PURPOSE After an additional 2 years of(More)
OBJECTIVE To assess the value of micronuclei in the characterization of precancerous lesions of the oral cavity with reference to their likelihood of progressing to malignant lesions. STUDY DESIGN The frequency of micronuclei was determined in exfoliated cells from normal oral mucosa, a preneoplastic condition (leukoplakia) and precancerous lesions with(More)
OBJECTIVE The authors report their experience in patients with adjuvant systemic 2-interferon with the aim of defining the effectiveness, side-effects, indications and limitations of this treatment. MATERIALS AND METHODS From January 1989 to December 1996, 123 patients with genital, anorectal and perineal HPV lesions were treated with cryosurgery;(More)
PURPOSE To determine whether pretherapy cell kinetics can predict local control for patients affected by head and neck squamous cell carcinomas (HN-SCCs) to be treated by primary radiotherapy and, moreover, guide to a choice between conventional and accelerated radiotherapy. PATIENTS AND METHODS Between 1989 and 1993, 83 patients with stage II to IV(More)
OBJECTIVE To evaluate the influence of methodologic variables, staining method and sampling, on the frequency of micronuclei scored in squamous epithelial cells of oral mucosa. Micronuclei were used as biomarkers of structural and numerical chromosome damage. STUDY DESIGN Feulgen and Giemsa stain and fluorescent dyes Hoechst 33258 and propidium iodide(More)
The efficacy of ten daily injections of 500 or 500,000 U of recombinant interleukin 2 (IL-2) day-1 given 1.5 cm from the insertion of the sternocleidomastoid muscle on the mastoid was evaluated in 31 patients with recurrent head and neck squamous cell carcinoma. No toxic effects were noted. One complete response (CR) and three partial responses (PRs) were(More)
The recent introduction of biomarkers in population studies of lung cancer has improved the traditional epidemiological approach, especially in the detection of high risk groups. Many inhalable carcinogens form DNA adducts, an initial event in lung carcinogenesis, and therefore the identification of easily accessible sources of DNA for population studies is(More)
The authors report their clinical experience regarding an original method of surgical repair of oro-sinusal communications. From September 1999 to December 2003, 13 patients (7 male and 6 female patients; mean age: 52 years, range: 24-68 years) underwent surgical repair of an oro-antral fistula by means of cryoplatelet gel: in three patients, it was mixed(More)
The purpose of the study was to determine whether pretreatment tumor cell kinetics can predict local control in elderly patients affected by squamous cell carcinoma of the head and neck (SCC-HN) and help guide different therapeutic modalities. Over a 6-year period, 52 patients with stage II to IV SCC-HN and aged more than 70 years were given an infusion of(More)
The authors report their experience on six male patients and one female patient (age range: 58-76 years, median: 67) with facial tumours involving the anterior skull base, undergoing craniofacial resection between January 1992 and May 1994 at the Division of Surgical Oncology in the Tumor Institute, Genoa. Three patients had squamous carcinoma and(More)
