Acute lung injury and acute respiratory distress syndrome after pulmonary resection

BACKGROUND: In this study we investigate the frequency and mortality of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) after pulmonary resection. METHODS: Patients that underwent pulmonary resection at the Royal Brompton Hospital between 1991 and 1997 were included. The case notes of all patients developing postoperative complications were retrospectively reviewed. RESULTS: The overall combined frequency of ALI and ARDS was 3.9%. The frequency was higher in patients over 60 years of age, males and those undergoing resection for lung cancer. ALI/ARDS caused 72.5% of the total mortality after resection in this series. CONCLUSIONS: In our experience ALI and ARDS are major causes of mortality after lung resection.     

Cancer Resection on the Residual Lung After Pneumonectomy for Bronchogenic Carcinoma

Background. After pneumonectomy for bronchogenic carcinoma, the residual lung may be the site of a new lung cancer or metastatic spread.

Methods. From 1989 to 1995, 13 patients with carcinoma on the residual lung after pneumonectomy for lung cancer were operated on. Three segmentectomies and 7 simple wedge resections were performed, 2 patients had multiple wedge resections, and 1 patient had an exploratory thoracotomy. Nine patients had a primary metachronous bronchogenic carcinoma, 3 had metastases from bronchogenic carcinoma, and no definite conclusion was reached in 1 case.

Results. No postoperative mortality was observed. Four patients had postoperative complications. The mean postoperative hospital stay was 14 days. Seven patients are alive, including 5 patients without evidence of disease. Six patients died of their disease, all with pulmonary recurrences. The overall median survival was 19 months, with a probability of survival at 3 years (Kaplan-Meier) of 46% (95% confidence interval, 22% to 73%).

Conclusions. Limited pulmonary resection for lung cancer after pneumonectomy for bronchogenic carcinoma is feasible with very low morbidity. In highly selected patients, surgical resection might prolong survival.     

Age does not influence early and late tumor-related outcome for bronchogenic carcinoma

BACKGROUND: The influence of age on early and late outcome after surgical resection of bronchogenic carcinoma is unknown. In an attempt to clarify this issue, we reviewed the outcome of 212 consecutive patients with primary lung cancer who had surgical treatment for bronchogenic carcinoma. METHODS: Ninety-two patients were younger than 50 years (group 1), and 120 patients were older than 70 years of age (group 2). Squamous cell carcinoma and adenocarcinoma were the most common histologic types in both groups. According to the new international staging classification, a similar proportion of stage I, II, and III were observed in both groups. RESULTS: Only the rate of pneumonectomy was significantly higher in younger patients (41% versus 22%, p = 0.002). The overall operative mortality rate in group 1 was 2.2% and 2.6% after pneumonectomy. In group 2 the overall mortality rate was 2.5% and 3.8% after pneumonectomy. Advanced age did not affect operative mortality. The adjusted (tumor-related) survival rate at 5 years was 56% in group 1 and 53% in group 2 (p = 0.93). The adjusted survival rate for patients with stage I was 61% in group 1 and 65% in group 2 (p = 0.21), and for stage IIIa 39% in group 1 and 48% in group 2 (p = 0.43). The adjusted 5-year survival rate was 56% in group 1 and 59% in group 2 for squamous cell carcinoma (p = 0.53) and 49% in group 1 and 42% in group 2 for adenocarcinoma (p = 0.76). CONCLUSIONS: Perioperative risk and midterm survival were similar in younger and older patients after surgical resection of bronchogenic carcinoma. We believe that this result is because surgical candidates constitute already a highly selected group of patients. From these data it is not possible to conclude that biologic behavior of lung cancer is more aggressive in younger patients.     

Carinal resection of bronchogenic carcinoma

Carinal resection was performed in 10 cases of bronchogenic carcinoma during 12 year-period. The mean age of patients was 58 years, with a range of 42 to 68 years. There were 7 male and 3 female. The tumor was located on the right side in 7 cases, on the left side in 1 case on the carina in 2 cases. The histological examination showed squamous cell carcinoma in 5 cases, adenocarcinoma in 4 cases and adenoid cystic carcinoma in 1 case. The staging revealed T3N2 M0 Stage IIIA in 2 cases, T4N0M0 Stage IIIB in 1 case, T4N1M0 Stage IIIB in 1 case, T4N2M0 Stage IIIB in 5 cases and T4N3M0 Stage IIIB in 1 case. The surgical methods were as follows; sleeve pneumonectomy in 5 cases, wedge carinal resection with pulmonary resection in 3 cases (right sleeve upper lobectomy in 2 cases and right pneumonectomy in 1 case), carinal resection in 2 cases. The site of bronchial anastomosis was overlapped by thymus in 6 cases. The 30-day mortality rate in tracheo-carinal resection was 10% (one patient). Eight patients died and remaining 2 patients are still alive without any evidence of recurrence. 5-year survival rate was 36%. These outcomes were almost equal to those of surgical case in the same stage.     

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.     

Survival and prognosis following resection of primary non small cell bronchogenic carcinoma.

A prospective follow up was carried out on 479 consecutive patients who underwent lung resection for non small cell primary bronchogenic carcinoma between 1980 and 1987 under the care of one surgeon at Guy's Hospital and Brook Hospital, London. The mean age of patients was 61.8 years; 16.9% were aged 70 years or over. Of the 479,237 patients had stage I disease, 108 patients stage II disease, and 134 patients stage III. Lobectomy was performed in 280 patients, pneumonectomy in 191, and wedge resection in 8. Operative mortality was 5% overall, 6.8% following pneumonectomy and 3.9% following lobectomy. There was no operative mortality following wedge resection. Old age did not affect operative mortality. Overall actuarial survival was 76.2% and 39.8% at 1 year and 5 years postoperatively, respectively (stage I: 86% and 55%; stage II: 77.8% and 35.5%; stage III: 57.5% and 16.2%). There were statistically significant differences in survival between the stages. Five-year actuarial survival was 45% for squamous cell carcinoma, 36.3% for adenocarcinoma, 31.9% for dimorphic carcinoma and a 21% for undifferentiated carcinoma. There were statistically significant differences in survival between undifferentiated carcinoma and each of the other cell types. The favourable survival in stage I disease lends weight to the concept that there is hope for cure in patients with early non small cell lung cancer.     

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.     

Is there a role for pneumonectomy in pulmonary metastases?

Background. Although sublobar and lobar resections are accepted operations for pulmonary metastases, pneumonectomy is viewed as a major incursion on Stage IV patients. We considered it important to ascertain the current results of pneumonectomy for pulmonary metastases since little information is available.

Methods. Of the 5,206 patients with pulmonary metastasectomy reported by the International Registry of Lung Metastases, 133 (3%) underwent primary, and 38 (1%) completion pneumonectomy between 1962 and 1994. Data were analyzed to determine the operative mortality rates, survival rates, and determinants of survival.

Results. Primary pneumonectomy was performed for metastatic disease mainly from epithelial (49%, 65 of 133) and sarcomatous (33%, 43 of 133) tumors. Indications were central lesion, eg, proximal endobronchial or hilar nodal metastases. Operative mortality was 4% (4 of 112) and a 5-year survival rate of 20% was achieved following complete resection (R0) in 112 patients. In contrast, the 21 incompletely resected patients had an operative mortality rate of 19% (4 of 21), and the majority did not survive beyond 2 years (p = 0.02). Survival was determined by the completeness of resection and not histology of the primary tumor, number of metastases, nodal status, and disease-free interval. In the 38 completion pneumonectomy patients, 35 were operated for recurrent disease and 3 for residual disease. Sarcomatous secondaries predominated in 28 patients. Complete resection was achieved in 31 patients (82%). The operative mortality rate was 3% (1 of 38 patients) and the 5-year survival rate was 30%.

Conclusions. Pneumonectomies for pulmonary metastases, albeit infrequently performed, were associated with acceptable operative mortality and long-term survival when performed in selected patients amenable to complete resection.     

Risk factors for acute lung injury after thoracic surgery for lung cancer

Acute lung injury (ALI) may complicate thoracic surgery and is a major contributor to postoperative mortality. We analyzed risk factors for ALI in a cohort of 879 consecutive patients who underwent pulmonary resections for non-small cell lung carcinoma. Clinical, anesthetic, surgical, radiological, biochemical, and histopathologic data were prospectively collected. The total incidence of ALI was 4.2% (n = 37). In 10 cases, intercurrent complications (bronchopneumonia, n = 5; bronchopulmonary fistula, n = 2; gastric aspiration, n = 2; thromboembolism, n = 1) triggered the onset of ALI 3 to 12 days after surgery, and this was associated with a 60% mortality rate (secondary ALI). In the remaining 27 patients, no clinical adverse event preceded the development of ALI-0 to 3 days after surgery-that was associated with a 26% mortality rate (primary ALI). Four independent risk factors for primary ALI were identified: high intraoperative ventilatory pressure index (odds ratio, 3.5; 95% confidence interval, 1.7-8.4), excessive fluid infusion (odds ratio, 2.9; 95% confidence interval, 1.9-7.4), pneumonectomy (odds ratio, 2.8; 95% confidence interval, 1.4-6.3), and preoperative alcohol abuse (odds ratio, 1.9; 95% confidence interval, 1.1-4.6). In conclusion, we describe two clinical forms of post-thoracotomy ALI: 1). delayed-onset ALI triggered by intercurrent complications and 2). an early form of ALI amenable to risk-reducing strategies, including preoperative alcohol abstinence, lung-protective ventilatory modes, and limited fluid intake. IMPLICATIONS: In an observational study including all patients undergoing lung surgery, we describe two clinical forms of acute lung injury (ALI): a delayed-onset form triggered by intercurrent complications and an early form associated with preoperative alcohol consumption, pneumonectomy, high intraoperative pressure index, and excessive fluid intake over the first 24 h.     

Stage I non-small cell lung carcinoma: really an early stage?

OBJECTIVE: We review our results on surgical treatment of patients with stage I non-small cell lung carcinoma and we attempted to clarify the prognostic significance of some surgical--pathologic variables. METHODS: From 1993 to 1999, 667 patients received curative lung resection and complete hilar and mediastinal lymphadenectomy for non-small cell lung cancer. Of these, there were 436 Stage I disease (65%), of whom 144 T1N0 and 292 T2N0. No patients had pre- or postoperative radio- or chemotherapy. Prognostic significance of the following independent variables was tested using univariate (log-rank) and multivariate (Cox proportional-hazards) analysis: type of resection (sublobar vs lobectomy vs pneumonectomy), histology (squamous cell vs adenocarcinoma), tumour size (3cm), histologic vascular invasion, visceral pleura involvement, positive bronchial resection margin, general T status. RESULTS: Overall 5-year survival was 63%. In both univariate and multivariate survival analysis, significant prognostic factors were histology (adenocarcinoma 65% vs squamous cell carcinoma 51%), tumour size (3cm 46%), and the presence of negative resection margin. Five-year survival by general T status was 66% in T1N0 vs 55% in T2N0 disease (P=0.19). CONCLUSIONS: Despite advances in early diagnosis and surgical technique, 5-year survival of stage I non-small cell lung carcinoma remains low as compared to survival of other solid organ neoplasm.

Second primary bronchogenic carcinoma: life-table analysis of surgical treatment.

Twelve patients had curative resection of primary bronchogenic carcinoma. Eleven to 84 months later, a second primary bronchogenic carcinoma was discovered and was operated on. Six patients underwent wedge resection, while the others had a lobectomy or pneumonectomy. There was no operative mortality. Two patients survived longer than 5 years. In addition to these patients, 26 patients who also had successive surgical resections for primary lung cancers were collected from the literature. Two operative deaths were related to respiratory insufficiency. Life-table analysis of this accumulated series of 38 patients revealed the survival rate 1 year after the resection of a second tumor to be 70%, and 2 and 3 years later, 55% and 27%, respectively. Thus, in patients in whom a second primary carcinoma of the lung develops, successive resections tailored to preserve respiratory reserve are compatible with low operative mortality and, in some instances, long-term survival.     

Bronchoplastic methods in the resection treatment of malignant bronchial tumors

1548 patients who were hospitalized 1964--1975 for diagnosis and treatment of bronchogenic carcinoma, 779 underwent resection. 17 patients could be operated by lobectomy or bilobectomy and bronchial resection (sleeve resection). Postoperative complications were frequent (n = 8): 4 times bronchopleural fistula, 2 times empyema, once fatal pneumonia and once bronchial stenosis. The overalll mortality and the survival rates are comparable to those of patients with radical resections. Sleeve resection is therefore a suitable alternative to pneumonectomy in elderly patients with reduced pulmonary function, rarely indicated also by a favourable tumor size. Sleeve resection increases the resectability of malignant bronchogenic tumors by 2%. Methods to prevent or cure the postoperative complications consisted in the use of absorbable suture material and long lasting intrathoracic suction.     

Completion pneumonectomy in cancer patients: experience with 55 cases.

OBJECTIVE: Analysis of a single institution experience with completion pneumonectomy. METHODS: From 1989 to 2002, 55 consecutive cancer patients received completion pneumonectomy (mean age 62 years; 25-79). Indications were bronchogenic carcinoma in 38 patients (4 first cancers, 8 recurrent cancers, 26 second cancers), lung metastases in three (one each from breast cancer, colorectal neoplasm and lung cancer), lung sarcoma in one, and miscellaneous non-malignant conditions in 13 patients having been surgically treated for a non-small cell lung cancer previously (bronchopleural fistula in 4, radionecrosis in 3, aspergilloma in 2, pachypleura in 1, massive hemoptysis in 1 and pneumonia in 2). Before completion pneumonectomy, 50 patients had had a lobectomy, three a bilobectomy, and two lesser resections. The mean interval between the two procedures was 51 months for the whole group (1-469), 60 months for lung cancer (12-469), 43 months for pulmonary metastases (21-59) and 29 months for non-malignant disorders (1-126). RESULTS: There were 35 right (64%) and 20 left (36%) resections. The surgical approaches were a posterolateral thoracotomy in 50 cases (91%) and a lateral thoracotomy in five cases (9%). Intrapericardial route was used in 49 patients (89%). Five patients had an extended resection (2 chest wall, 1 diaphragm, 1 subclavian artery and 1 superior vena cava). Operative mortality was 16.4% (n=9): 11.9% for malignant disease (n=5) and 30.8% for benign disease (n=4) Operative mortality was 20% for right completion pneumonectomies (n=7) and 10% for left-sided procedures (n=2) Twenty-three patients (42%) experienced non-fatal major complications. Actuarial 3- and 5-year survival rates from the time of completion pneumonectomy were 48.4 and 35.2% for the entire group. Three- and five-year survival for patients with bronchogenic carcinoma were 56.9 and 43.4%, respectively. CONCLUSIONS: These results suggest that completion pneumonectomy in the setting of lung malignancies can be done with an operative risk similar to the one reported for standard pneumonectomy. In contrast, in cancer patients, completion pneumonectomy for inflammatory disorders is a very high-risk procedure.     

Carinal resection for bronchogenic carcinoma

The purpose of this study was to evaluate the results of carinal resection for bronchogenic carcinoma in our institute. From 1981 to 1999, 24 carinal resection were performed for squamous cell carcinoma (n = 19), adenoid cystic carcinoma (n = 2), small cell carcinoma (n = 1), adenocarcinoma (n = 1), and mucoepidermoid carcinoma (n = 1). Nineteen underwent sleeve pneumonectomy, 2 had carinal resection without lung resection, 2 had carinal resection with right middle and lower lobectomy, and 1 had wedge pneumonectomy. In the patients with sleeve or wedge pneumonectomy, there were 5 operative death and 3 patients had survived for more than 3 years. Two patients with low-grade malignant tumors underwent carinal resection without lung resection and survived more than 10 years. We believe that limited carinal resection for low-grade malignant tumors are safe and valuable procedure. Careful selection of patients with sleeve or wedge pneumonectomy is mandatory.     

限制补液在胸外伤继发急性肺损伤或急性呼吸窘迫综合征治疗中的应用

目的总结限制补液在胸外伤合并急性肺损伤(ALI)或急性呼吸窘迫综合征(ARDS)治疗中的应用效果。方法单纯胸外伤合并ALI或ARDS患者132例,采用限制补液技术,适当减少补液,加控制性降压技术,收缩压控制在95~110mmHg之间,早期以维持一个满足基本灌注的偏低血压作为目标血压,减少输液量和速度。通过单纯胸部外伤(排除其他部位重症损伤的干扰)的救治,总结呼吸窘迫防治特点。结果 ALL/ARDS气管插管率为17.4%(23/132),气管切开的发生率为3.8%(5/132),死亡率为2.3%(3/132)。结论 ALI时不恰当的补液过多引发肺水肿是单纯胸外伤并发ARDS主因,而不是反常呼吸所致。适当控制输液,辅以控制性降压技术能大大降低重症胸外伤死亡率。     

Lung resection for bronchogenic carcinoma after pneumonectomy: a safe and worthwhile procedure.

OBJECTIVES: Patients treated surgically for lung cancer can develop either a metachronous cancer or a recurrence. The appearance of a new cancer on the remaining lung after a pneumonectomy poses unique treatment problems, and surgery is often considered contraindicated. We report on the outcome of resections for lung cancer after pneumonectomy performed for lung cancer. METHODS: We reviewed the records of patients who underwent a resection of bronchogenic carcinoma on the remaining lung from 1990 to 2002. RESULTS: There were 14 patients (13 males and 1 female) with a median age of 64 years (range 51-74). Median preoperative Fev1 was 1.45 (range 1.35-2.23), corresponding to 59% of predicted Fev1 (range 46-80%). Resection was performed between 11 and 264 months after pneumonectomy (median 35.5). The resections performed were: one wedge resection in 11 patients, two wedge resections in two patients and two segmentectomies in two other patients; one patient underwent a third resection. Diagnosis was metachronous cancer in 12 patients and metastasis in two patients. Complications occurred in three patients (21%), while operative mortality was nil. Mean hospital stay was 10.5 days (6-25). Two patients received chemotherapy (one after local recurrence, one after the third resection). Overall 1, 3 and 5 year survivals were 57, 46 and 30%, respectively (median 21 months). For patients with a metachronous cancer they were 69, 55 and 37% (median 57 months), respectively, while neither patient with a metastatic tumor survived 1 year (P=0.03). CONCLUSIONS: Limited lung resection on a single lung is a safe procedure associated with acceptable morbidity and mortality rates. In patients with a metachronous lung cancer, long-term survival with a good quality of life can be obtained with limited resection on the residual lung.     

Lung injury in patients following thoracotomy.

BACKGROUND--Postoperative lung injury is a recognised complication of thoracotomy for which there are few data regarding incidence and outcome. METHODS--In a case controlled study the notes of all adult patients who developed acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) following thoracotomy between 1991 and 1994 were examined and classified according to the guidelines of the American Thoracic Society/European Respiratory Society for ALI/ARDS. The predictive value of a routine preoperative assessment and duration of anaesthesia in determining those patients most likely to develop ALI/ARDS was assessed. RESULTS--Between 1991 and 1994 231 lobectomies, 103 pneumonectomies, and 135 wedge resections and segmentectomies were performed. The overall incidence of lung injury was 5.1%; 17 patients developed ARDS (two survived) and seven developed ALI (five survived). There was no significant difference compared with case matched controls in preoperative spirometric values, arterial oxygen tension (PaO2), or duration of anaesthesia. None of these parameters was useful in predicting those patients most likely to develop lung injury. CONCLUSION--Lung injury after thoracotomy is associated with a high mortality. Conventional parameters for preoperative assessment do not predict those patients most likely to develop ALI/ARDS in these circumstances.     

Video-assisted thoracic surgical resection of malignant lung tumors.

Forty patients with malignant pulmonary disease underwent evaluation, staging, and a biopsy or resection by means of video-assisted thoracic surgery. There were 20 men and 20 women whose ages ranged from 27 to 82 years. Eight patients had a wedge resection for metastatic carcinoma, three a lobectomy for primary carcinoma, six exploration of the thorax, five biopsy of the aortopulmonary window, and eighteen a sublobar resection for primary carcinoma of the lung. There was no mortality. Three patients had air leaks that lasted an average of 8 days. Video-assisted thoracic surgery seems to be useful for more precise staging of carcinoma of the lung, and, in some patients, resectional operations can be performed.     

The influence of race on the development of acute lung injury in trauma patients

Background

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are sequelae of severe trauma. It is unknown if certain races are at greater risk of developing ALI/ARDS, and once established, if there are racial differences in the severity of lung injury or mortality.

Methods

Retrospective cohort study of 4,397 trauma patients (1,831 Caucasians, 871 African-Americans, 886 Hispanics, and 809 Asian/Pacific Islanders) requiring intensive care unit (ICU) admission between 1996 and 2007 at an urban Level I trauma center.

Results

African-American patients were most likely to present in shock with penetrating trauma and receive a massive transfusion. The incidence of ALI/ARDS was similar by race (P = .99). Among patients who developed ALI/ARDS, there was no evidence to support a difference in partial pressure of oxygen in arterial blood to fraction of inspired oxygen (Pao₂/Fio₂) (P = .33), lung injury score (P = .67), or mortality (P = .78) by race.

Conclusions

Despite differences in baseline characteristics, the incidence of ALI/ARDS, severity of lung injury, and mortality were similar by race.     

Factors associated with perioperative complications and long-term results after pulmonary resection for primary carcinoma of the lung.

OBJECTIVE: The aim of this study was to describe perioperative morbidity and mortality of patients presenting with resectable lung cancer and to investigate the long-term survival. METHODS: We reviewed the records of 344 patients who underwent lung resection for bronchogenic carcinoma. Follow-up information was obtained from visits to the outpatient clinic. RESULTS: Between January 1991 and December 1995 there were 263 males and 81 females included with a mean age of 65.7 years. One hundred and eight (31%) patients underwent a pneumonectomy, 159 (46%) a lobectomy, 43 (13%) a bilobectomy, four (1%) a segmental resection and 30 (9%) an explorative thoracotomy. A total of 341 complications occurred. The 30 day mortality rate was 7.9% (27 patients). Patients with a low FEV1% and older patients have a higher risk of mortality within 30 days. Postoperative myocardial infarction and pneumonia were associated with an increase in 30 day mortality. The median survival was 3.6 years for stage I, 1.9 years for stage II, 1.0 years for stage IIIa, 0.9 years for stage IIIb and 0.9 years for stage IV. Prognostic factors for the long-term survival included stage, pneumonectomy, percentage FEV1 <70, and large cell carcinoma. CONCLUSIONS: Pulmonary resection can be performed at an acceptable risk. Critical reviewing of our results made it possible to make recommendations for improvements.
