Survival Experience Following Nd:YAG Laser Photoresection for Primary Bronchogenic Carcinoma: Metastatic diseaseSurvival rates by cell type and by metastatic disease status were similarly analyzed for patients in the control group All 58 patients in this group had either bronchoscopically proved exophytic obstructive disease or had x-ray evidence of postobstructive pneumonitis, lobar collapse, or complete collapse of the lung. All 58 patients had died in this group as of date of last contact Tumor registry records were used to confirm the date of death in all cases. On initial presentation, 11 patients in the control group had asphyxiation, massive hemoptysis, or postobstructive pneumonitis associated with hypoxia or septicemia secondary to endobronchial exophytic lesions.

They received emergency XRT as the initial therapeutic intervention and would have undergone YPR were it available at that time. The survival rates of these 11 were compared with those of patients who underwent emergency YPR as the initial therapeutic intervention for similar lesions between 1983 and 1986 and were subsequently treated with conventional XRT (n = 15). The other 47 patients in the control group underwent XRT at varied intervals after diagnosis of inoperability. In spite of roentgenographic or bronchoscopic determination of obstructive airway disease, it is difficult to ascertain from chart review whether these 47 patients were symptomatic from endobronchial disease at initiation of XRT. This group is similar to the 20 patients who had completed or were undergoing XRT for similar inoperable lesions before worsening symptoms led to referral for YPR.
Analytical comparison was made between the survival distributions of all patients with NSCLC who underwent XRT alone from 1981 to 1983 (n = 58) vs patients who underwent both conventional XRT as well as YPR from 1983 to 1986 (n = 35). Two patients with small cell carcinoma who underwent YPR were dropped from these comparative analyses.
