Abstract：

Objective To verify the outcome and long-term survival of surgical management for double primary lung cancers. Methods The clinical data of 98 patients with double primary lung cancers admitted between January 1999 and June 2009 was analyzed retrospectively. There were 72 cases of synchronous double primary lung cancers, including 54 males and 18 females with median age of onset of 66 years (37 to 79 years). Thoracic surgical procedures for 144 tumor lesions included lobectomy for 9 cases, bilobectomy for 14 cases, pneumonectomy for 6 cases, lobectomy plus wedge resection for 33 cases, double wedge resection for 9 cases, and bilobectomy plus wedge resection for 1 case. There were 26 cases of metachronous double primary lung cancers, including 20 males and 6 females. The median age for the first primary cancer was 59. 5 years (38 to 73 years) , for second primary cancer was 66 years (47 to 77 years). Thoracic surgical procedures for 52 tumor lesions included lobectomy for 31 cases, bilobectomy for 1 cases, wedge resection for 10 cases, and pneumonectomy for 8 cases. Results The overall 30-day mortality was 0.Postoperative complications rate was 13. 3% . All patients were followed up after the operation. Until December 2009, follow-up rate was over 90%. Five-year survival for all the patients from the time of initial diagnosis of cancer was 66. 4%. Five-year survival for patients with metachronous and synchronous disease from the time of initial diagnosis of cancer was 96. 2% and 43. 0% ( P =0. 000) , respectively. Survival at 5 years for the second cancer of metachronous disease and synchronous disease was 45. 9% and 43. 0% (P =0. 634) ,respectively. Conclusion Surgical treatment for double primary lung cancer is reasonable, and the patients can make long-term survival.

Multiple primary lung cancers. Results of surgical treatment

During a 13-year period, multiple primary lung cancers were diagnosed in 80 consecutive patients. Forty-four patients had metachronous cancers. The initial pulmonary resection was lobectomy in 36 patients, bilobectomy in 3, pneumonectomy in 1, and wedge excision or segmentectomy in 4. The second pulmonary resection was lobectomy in 16 patients, bilobectomy in 2, completion pneumonectomy in 7, and wedge excision or segmentectomy in 19. There were two 30-day operative deaths (mortality rate, 4.5%). Actuarial 5- and 10-year survival rates after the first pulmonary resection for stage I disease were 55.2% and 27.0%, respectively. Five-year and 10-year survival rates for stage I disease after the second pulmonary resection were 41.0% and 31.5%, respectively. The remaining 36 patients had synchronous cancers. The pulmonary resection was lobectomy in 18 patients, bilobectomy in 3, pneumonectomy in 10, and wedge excision or segmentectomy in 8. There were two 30-day operative deaths (mortality rate, 5.6%). Actuarial overall 5- and 10-year survival rates after pulmonary resection were 15.7% and 13.8%, respectively. We conclude that an aggressive surgical approach is safe and warranted in most patients with multiple primary lung cancers and that the presence of synchronous primary cancers is ominous.     

Subsequent pulmonary resection for bronchogenic carcinoma after pneumonectomy

BACKGROUND: Patients who have undergone a pneumonectomy for bronchogenic carcinoma are at risk of cancer in the contralateral lung. Little information exists regarding the outcome of subsequent lung operation for lung cancer after pneumonectomy. METHODS: The records of all patients who underwent lung resection after pneumonectomy for lung cancer from January 1980 through July 2001 were reviewed. RESULTS: There were 24 patients (18 men and 6 women). Median age was 64 years (range, 43 to 84 years). Median preoperative forced expiratory volume in 1 second was 1.47 L (range, 0.66 to 2.55 L). Subsequent pulmonary resection was performed 2 to 213 months after pneumonectomy (median, 23 months). Wedge excision was performed in 20 patients, segmentectomy in 3, and lobectomy in 1. Diagnosis was a metachronous lung cancer in 14 patients and metastatic lung cancer in 10. Complications occurred in 11 patients (44.0%), and 2 died (operative mortality, 8.3%). Median hospitalization was 7 days (range, 2 to 72 days). Follow-up was complete in all patients and ranged between 6 and 140 months (median, 37 months). Overall 1-, 3-, and 5-year survivals were 87%, 61%, and 40%, respectively. Five-year survival of patients undergoing resection for a metachronous lung cancer (50%) was better than the survival of patients who underwent resection for metastatic cancer (14%; p = 0.14). Five-year survival after a solitary wedge excision was 46% compared with 25% after a more extensive resection (p = 0.54). CONCLUSIONS: Limited pulmonary resection of the contralateral lung after pneumonectomy is associated with acceptable morbidity and mortality. Long-term survival is possible, especially in patients with a metachronous cancer. Solitary wedge excision is the treatment of choice.     

Video-assisted thoracic surgery for metachronous lung cancer

Of 1,391 patients who underwent operation for primary lung cancer between 2000 and 2009, 50 patients (3.6%) had a past history of pulmonary resection for lung cancer. Three patients underwent completion pneumonectomy by thoracotomy and in the other 47 patients video-assisted thoracic surgery (VATS) was performed. We considered 42 cases (3 of completion pneumonectomy and 39 of VATS) to be metachronous lung cancer and 8 cases of VATS to be recurrence by detailed histologic assessment. We examined 39 cases of metachronous lung cancer resected by VATS. The patients were aged 68 +/- 8 years and 4 patients were aged 80-years or more. The surgical procedures performed were lobectomy in 4 patients, segmentectomy in 3, and wedge resection in 40. The operation time was 121 +/- 66 minutes and the blood loss was 67 +/- 140 ml. There were no major complications. We registered 6 deaths during follow-up; 3 were due to disease progression and 3 were due to other causes. The survival rate of the 42 patients including 3 patients who underwent completion pneumonectomy was 74.9% at 5 years. Early detection of metachronous lung cancer and surgical resection offers a favorable prognosis.     

Iterative surgical resections for local recurrent and second primary bronchogenic carcinoma.

OBJECTIVE: To report our experience with repeated pulmonary resection in patients with local recurrent and second primary bronchogenic carcinoma, to assess operative mortality and late outcome. METHODS: The medical records of all patients who underwent a second lung resection for local recurrent and second primary bronchogenic carcinoma from 1978 through 1998 were reviewed. RESULTS: There were 27 patients. They constituted 2.5% of 1059 patients who had undergone lung resection for bronchogenic carcinoma in the same period. Twelve patients (1.1%) (group 1) had a local recurrence that developed at a median interval of 24 months (range 4-83).The first pulmonary resection was lobectomy in ten patients and segmentectomy in two. The second operation consisted of completion pneumonectomy in ten cases, completion lobectomy in one and wedge resection of the right lower lobe after a right upper lobectomy in one. The other 15 patients (1.4%) (group 2) had a new primary lung cancer that developed at a median interval of 45 months (range 21-188).The first pulmonary resection was lobectomy in 12 patients, bilobectomy in one and pneumonectomy in two. The second pulmonary resection was controlateral lobectomy in seven patients, controlateral sleeve lobectomy in two, controlateral pneumonectomy in 1, controlateral wedge resection in four and completion pneumonectomy in one. Overall hospital mortality was 7.4%, including one intraoperative and one postoperative death in group 1 and 2, respectively. Five-year survival after the second operation was 15.5 and 43% with a median survival of 26 and 49 months in groups 1 and 2, respectively (P=ns). CONCLUSIONS: Long-term results justify complete work-up of patients with local recurrent and second primary bronchogenic carcinoma. Treatment should be surgical, if there is no evidence of distant metastasis and the patients are in good health. Early detection of second lesions is possible with an aggressive follow-up conducted maximally at 4 months intervals for the first 2 years and 6 months intervals thereafter throughout life.     

Surgical treatment for bilateral multiple lung cancers]

We reviewed 21 patients with bilateral multiple bronchogenic carcinomas. Eleven of them had synchronous carcinomas and 10 had metachronous carcinomas. We treated 6 patients with lobectomy and wedge resection under median sternotomy synchronously, and 2 patients with lobectomy on both lungs under standard thoracotomy, 2 patients with lobectomy and wedge resection, 1 patient with segmentectomy on both lung, 1 patient with lobectomy and segmentectomy, 1 patient with pneumonectomy and wedge resection, and 8 patients with lobectomy and thoracoscopic wedge resection on each lung metachronously. Two patients who had lobectomy on both lungs were dead, one of whom of pulmonary edema 2 weeks after second operation and the other of respiratory failure 3 years after second operation. We concluded that lobectomy on both lungs are not recommended because of high mortality rate (10%) and the limited resection under thoracoscopic surgery should be considered to treat the other contra lateral primary lung cancers.     

Surgical management of metachronous bronchial carcinoma

Objective: To assess the results of surgery for the treatment of metachronous bronchial carcinoma. Methods: From 1985 to 1999, 38 patients were operated on for a metachronous lung carcinoma, accordingly to the criteria of Martini. All tumors were staged using the new International Classification System revised in 1997. Results: Diagnosis of the second cancer was done at radiological follow-up in 30 asymptomatic patients. Seventeen metachronous locations were ipsilateral. Histology of the metachronous lesion was the same as that of the first tumour in 23 patients (60%). The first resection was a lobectomy (n=35), a pneumonectomy (n=2) and a carinal resection (n=1). The second one was a wedge resection (n=7), a segmentectomy (n=3), a lingulectomy (n=2), a lobectomy (n=9), a bilobectomy (n=1), and a pneumonectomy (n=16). There were five in-hospital deaths (13%). Completion pneumonectomy was performed in 15 patients, with one postoperative death (7%). The overall estimated 5 and 10-years actuarial survival rates from the treatment of the first cancer were 70 and 47% respectively. The 5-year survival rate after the treatment of the second cancer was 32% (median survival: 31 months), including the operative mortality. Survival was negatively affected by a resection interval of less than 2 years and the performance of atypical lung sparing pulmonary resection for the treatment of the second cancer. Conclusions: Good long-term results are achievable by the means of a second pulmonary resection in selected patients with metachronous lung cancer. Optimal cancer operations should be applied whenever functionally possible.     

Multiple primary lung carcinomas: prognosis and treatment

From 1955 to 1990, 111 patients have been treated for multiple primary lung carcinomas. Criteria for diagnosis were: (1) different histology (n = 44); or (2) same histology, but disease-free interval at least 2 years (n = 39), origin from carcinoma in situ (n = 19), or metachronous disease in different lobe (n = 9) with no cancer in common lymphatics or extrapulmonary metastasis at the time of diagnosis. The second cancer was synchronous in 33 patients (30%) and metachronous in 78 (70%). Metachronous disease developed at a median interval of 48 months. Five-year survival for patients with metachronous and synchronous disease from the time of initial diagnosis of cancer was 70% and 44%, and 10-year survival was 42% and 23%, respectively. Survival after the development of a metachronous lesion was 23% at 5 years. Survival from the time of initial diagnosis was significantly better for metachronous versus synchronous, late (24 month disease-free interval) versus early metachronous disease, and adenocarcinoma versus epidermoid carcinoma. The first cancer was completely resected in 103 patients (93%), but complete resection of a metachronous tumor was possible in only 54 patients (69%). Complete resection of second primary cancers resulted in significantly (p less than 0.0001) prolonged 5-year survival compared with incomplete resection (38% versus 9%). Excluding patients requiring pneumonectomy, initial resection limited subsequent resection in only 7 patients (9%) with metachronous disease. We conclude that patients surviving treatment of primary lung cancers require lifelong screening for multiple primary lung carcinoma, and complete resection is recommended whenever possible.
