Radiation-free weekend rescued! Continuous accelerated irradiation of 7-days per week is equal to accelerated fractionation with concomitant boost of 7 fractions in 5-days per week: report on phase 3 clinical trial in head-and-neck cancer patients.

Purpose: To report long-term results of randomized trial comparing 2 accelerated fractionations of definitive radiation therapy assessing the need to irradiate during weekend in patients with head and neck squamous cell carcinoma.

Methods And Materials: A total of 345 patients with SCC of the oral cavity, larynx, and oro- or hypo-pharynx, stage T2-4N0-1M0, were randomized to receive continuous accelerated irradiation (CAIR: once per day, 7 days per week) or concomitant accelerated boost (CB: once per day, 3 days per week, and twice per day, 2 days per week). Total dose ranged from 66.

Acute mucosal radiation reactions in patients with head and neck cancer. Patterns of mucosal healing on the basis of daily examinations.

Purpose: The goal of this research was to evaluate the healing processes of acute mucosal radiation reactions (AMRR) in patients with head and neck cancer.

Materials And Methods: In 46 patients with oral and oropharyngeal cancer patients irradiated with conventional (n = 25) and accelerated (n = 21) dose fractionation AMRR was evaluated daily during and after radiotherapy. Complex of morphological and functional symptoms according to the Dische score were collected daily until complete healing.

[[Radical radiotherapy in patients with laryngeal cancer in clinical material of Institute Oncology in Gliwice treated in year 1990-1996].

This paper presents influence of selected prognostic factors on results of laryngeal cancer radiotherapy used as the only treatment in 541 patients irradiated in Centre of Oncology-Institute in Gliwice between 1990-1996. The 3-year actuarial disease-free survival was 47.5% for supraglottic cancer and 67% for glottic cancer.

[The effectiveness of combined treatment for laryngeal cancer in Silesia region during the years 1987-1996].

Between 1987-1996, 484 patients with laryngeal cancer were treated by surgery and adjuvant radiotherapy. The 25-30% therapeutic gain was noted when to compare the first period of the study (1987-1992) with the second (1993-1996). The increment of effectiveness of combined treatment for larynx cancer is probably the result of better quality of surgical procedures and individualization of radiation treatment.

[Unconventional accelerated irradiation of advanced pharyngolaryngeal cancer as an alternative treatment compare to surgery. The interim results of randomized clinical trial].

The paper presents preliminary results (3 year tumour control and survival) of clinical randomized trial comparing accelerated fractionation (7 fx a week) with conventional (5 fx a week) radiotherapy (RT) for advanced pharyngo-laryngeal cancer. Significant treatment gain (p < 0.001) and good tolerance associated with accelerated RT was noted (82% of disease-free and 79% of overall survival).
