[Survival of patients with planocellular bronchial carcinoma who were treated conservatively and with surgery].

The paper presents the analysis of survival rate among 133 patients with squamous cell bronchial carcinoma during the five-year follow-up period, from 1985 to the end of 1989, treated at the Institute of Pulmonary Diseases and Tuberculosis in Belgrade. Duration of the survival was monitored in four therapeutical groups: B1 (surgically treated - 34 cases), B2 (conservatively treated using combined chemotherapy and irradiation therapy - 44 cases), B2-1 (treated with only chemotherapy - 32 cases) and B2-2 (treated with only irradiation therapy--23 cases). Maximal survival among the patients with squamous cell bronchial carcinoma was evidenced in surgically treated group of patients (8.8% survived for 5 years). Conservative therapy achieved three-year survival in 4.5% of group B2 patients and 9.4% of group B2-1 patients. Minimum survival was recorded in patients treated with a single irradiation therapy with maximal duration of 2 years achieved in 4.3% of cases. The mean duration of survival ranged from 28.1 +/- 15.2 months in group B1, being similar in groups B2 and B2-1 (15.3 +/- 8.0 and 15.1 +/- 8.2 months, respectively), while it was the least in the group B2-2: 8.8 +/- 6.4 months. Variance analysis revealed highly significant statistical difference in mean duration of survival among the patients with squamous cell bronchial carcinoma classified in different therapeutical groups (F = 107.783; p < 0.0001).
