Objective: Despite refinements of the diagnostic procedures, often surgery remains the only option to ascertain the histopathological nature of solitary pulmonary nodules (SPN). Aim of the present study was to ascertain the value of wide-margin wedge resection (WMWR) with curative intent in a consecutive cohort of patients afflicted by SPN. Methods: From January 1995 to January 2002, 129 patients (74 male, mean age 60.5±14.4 years) underwent WMWR of a SPN. In-hospital outcome was prospectively collected and retrospectively analyzed. Incidence of malignancy was obtained by histology. Patients found to be afflicted by primary lung cancer (PLC) were sub-grouped according to their preoperative cardiopulmonary status (CPS). In-hospital and mid-term clinical outcome of all the patients is presented. Results: There were 3 (2.3%) in-hospital deaths. Distribution of histology included 61 (47.3%) PLC (41 poor CPS), 20 (15.5%) secondary lung cancer (SLC), and 48 (37.2%) miscellaneous benign lesions. Twenty patients with PLC were fit and underwent completion lobectomy within 2 weeks following WMWR. Hospital length of stay was longer in patients with PLC as compared to patients with SLC (P=0.04). There were 17/61 (27%) recurrences in the PLC group. Of these, 2 occurred in fit patients undergone previous WMWR-lobectomy, and 15 in patients with poor baseline CPS. All these patients were referred for adjuvant therapy. Overall 5-year survival of the PLC group was 66% (61.1% for those with poor CPS and 82.5% for those with good CPR (P=NS). Seven out of 20 (35%) patients with SLC had late recurrent disease, leading to 1 re-operation. The overall 5-year survival in this group was 58.8%. There was only 1 non-related late death in the benign group. Conclusions: The WMWR resection of a primarily malignant SPN determines a valuable 5-year survival but a relatively high incidence of late recurrence. WMWR is a safe and effective surgical option for patients presenting with poor cardiopulmonary reserve.
