Intact p73 function is shown to be an important determinant of cellular sensitivity to anticancer agents. Inhibition of p73 function by dominant-negative proteins or by mutant p53 abrogates apoptosis and cytotoxicity induced by these agents. A polymorphism encoding either arginine (72R) or proline (72P) at codon 72 of p53 influences inhibition of p73 by a(More)
BACKGROUND Intensification of chemoradiation for advanced head and neck squamous cell carcinoma (HNSCC) is unlikely due to toxicity. Cetuximab combined either with radiotherapy or with chemotherapy showed favourable toxic profile with positive results in both combinations. Therefore, cetuximab could intensify chemoradiation without worsening toxicity. We(More)
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)
In vitro studies have identified 14-3-3sigma as a regulator of senescence in human keratinocytes. To assess its contribution to squamous neoplasia, we have analyzed genetic and epigenetic changes in this gene in squamous cell carcinomas (SCCs) and dysplastic lesions of the oral cavity. No mutations were detected in the coding sequence of 14-3-3sigma in 20(More)
PURPOSE OF REVIEW Surveillance of patients with a history of cancer is a frequent practice in oncology. However, it is often aimed at the early diagnosis of relapse and tends to underestimate the evaluation and care of factors impairing quality of life (QoL). Among these, long-term toxicities of anticancer treatments are one of the major threats to a(More)
PURPOSE The goal of the present analyses is to assess the association between different therapeutic approaches and both the probability of achieving a complete response and the risk of death in patients with stage III-IV, inoperable, squamous cell carcinoma of the head and neck (SCC-HN). PATIENTS AND METHODS Between August 1983 and December 1990, 273(More)
BACKGROUND Cancer and cisplatin-based chemotherapy both are well recognized risk factors for coagulation disorders and thrombosis. However, vascular events (VEs) seldom are considered adverse effects of treatment and may not even be taken into account in reports of chemotherapy trials. METHODS VEs were recorded prospectively in a population of patients(More)
AIMS AND BACKGROUND The TomoTherapy Hi-Art II system is able to deliver dynamic intensity-modulated radiation therapy within a helical geometry providing robust conformality and modulation, abrupt dose falloff, and reliable accuracy. A new upgrade named TomoDirect was introduced recently, allowing delivery of radiation at discrete angles with a fixed(More)
Aim of the present study was to test, activity and toxicity of a rapidly alternating chemoradiation (paclitaxel based) in 31 patients with unresectable, locally advanced or recurrent after surgery, head and neck cancer. Three-year overall survival and progression-free survival were 61.4 and 73.7%, respectively. Main side effects remain a major problem.
