Abstract

Background: The feasibility of anatomical lobectomy in patients with bronchial carcinoma in an area of severe heterogeneous emphysema whose respiratory reserve is outside operability guidelines has previously been confirmed. A review was undertaken to determine whether this approach is justified by long-term survival.

Methods: A single surgeon’s 8 year experience of 118 consecutive patients (74 men) of median age 70 years (range 45–84) who underwent upper lobectomy for pathological stage I non-small cell lung cancer (NSCLC) was reviewed. The preoperative characteristics, perioperative course and survival of the 27 cases with severe heterogeneous emphysema of apical distribution and a predicted postoperative forced expiratory volume in 1 s (ppoFEV₁) of <40% (lobarLVRS group) were compared with the remaining 91 cases with a ppoFEV₁ of >40% (control group).

Results: Postoperative mortality was 1 of 27 in the lobarLVRS group and 2 of 91 in the control group (p = NS). Five-year survival in the lobarLVRS group was 35% compared with 65% in the control group without concomitant severe emphysema (p = 0.001), although rates of tumour recurrence were similar.

Conclusions: Long-term survival after lobarLVRS for stage I lung cancer is limited by physiological rather than oncological factors. However, outcomes are still better than those reported for any other modality of treatment in this group of high-risk patients. This finding justifies the decision to offer lobectomy in these selected cases.
