Surgery for second lung cancers

Purpose: To evaluate the outcomes of patients surgically treated for their second primary lung cancer. Method: In a computerized surgical registry of > 800 consecutive patients t reated for primary pulmonary carcinoma since 1980, 37 patients presented wi th a second lung cancer. These patients were analyzed regarding their origi nal treatment, preoperative evaluation, operative procedures, and long-tem follow-up. Results: Three fifths of the patients were female, and 57% mere greater tha n or equal to 65 years old at the time of their second operation. One patie nt originally had two synchronous tumors; another patient had three metachr onous neoplasms. The interval between surgeries ranged from 5 to 239 months . In 31 patients, treatment for their original tumor was surgical resection alone. Lobectomy was the most common operation for the original tumor, and 78% were stage I. When the second tumor was diagnosed, 25 patients (68%) w ere asymptomatic. Eight patients (22%) were current smokers, and 29 patient s (78%) were former smokers. The most common operation for the second tumor was a lobectomy. Surgical mortality was 5.4%. Nineteen patients (51%) surv ived 2 years, and 9 patients (24%) survived greater than or equal to 5 year s. Eleven patients (30%) were still alive at last follow-up, 3 to 198 month s postoperatively, and only 13 patients (34%) had died of their cancer. Conclusion: Surgical treatment of second primary pulmonary neoplasms can be performed in selected patients with acceptable long-term survival.
