Are bilobectomies acceptable procedures?
BACKGROUND
Controversy about operative morbidity and oncologic value of bilobectomy has led to a review of our experience over the past 12 years.


METHODS
The charts of 112 patients (100 men and 12 women with a mean age of 63 years) were reviewed for operative mortality and morbidity and long-term survival. Survival of patients with stage I or stage II disease was compared with that of stage-matched and age-matched groups having right pneumonectomy.


RESULTS
Four patients (3.5%) died postoperatively. Nonfatal complications occurred in 55 patients (49%); the most frequent problem was pleural space disease (34%). Survival studies focused on the 96 patients with nonsmall cell bronchogenic cancer (44 in stage I, 32 in stage II, and 20 in stage IIIA). The overall 5-year survival rate was 40%; the 5-year survival rate was similar for stage I and stage II (41% for stage I, 50% for stage II, and 17% for stage IIIA). The incidence of local recurrence was significantly increased after bilobectomy for stage I cancer (chi 2 = 5.066; p < 0.05) compared with pneumonectomy but did not affect 5-year survival. Local recurrence and survival were similar after bilobectomy and pneumonectomy in stage II.


CONCLUSIONS
These data demonstrate an increased morbidity after bilobectomy. Survival studies demonstrate an increased risk of local recurrence in patients with stage I disease, which might be partly explained by understaging.
