title: [Evaluation of early results and failures of radiotherapy in patients with cancer of the oral cavity and throat].
abstract: Since 1986 to 1989 in the Department of Teleradiotherapy of Center Oncology--Institute branch Gliwice 102 patients with oral cavity cancers and 114 with pharyngeal cancers were treated. Patients underwent external radiation, which was delivered with Co60 to the dose 70 Gy on the tumor and additionally regional lymph nodes were irradiated with 10 MeV linear accelerator. There were 69 patients (32%) with stage T-2 and 147 patients (68%) in stage T-3. Metastatic regional lymph nodes in 130 patients (60%) were recognized. Free of disease one year survival in 98 patients (45%) was observed: 41% with oral cavity cancer and 49% with pharyngeal cancer. The conclusion suggests that the results depend on the size of the tumor and presence of the metastatic lymph nodes. Among the patients with oral cavity cancer in 40% with free nodes and 69% with metastatic nodes unsuccessful treatment was observed. In the group with pharyngeal cancer percentage were 35% and 63% respectively. Results of the treatment, were unsatisfactory when diameter of metastatic nodes was more than 5 cm (N-3).
