Mortality, complications and loss of pulmonary function after pneumonectomy vs. sleeve lobectomy in patients younger and older than 70 years

Retrospective single institution analysis of all patients undergoing sleeve lobectomy or pneumonectomy between 2000 and 2005. Seventy-eight patients underwent pneumonectomy (65 patients <70 years, 13 patients >70 years) and 69 sleeve lobectomy (50 patients <70 years, 19 patients >70 years). Pre-existing co-morbidity, surgical indication and induction therapy was similarly distributed between treatment by age-groups. In patients <70 years, pneumonectomy and sleeve lobectomy resulted in a 30-day mortality of 3% vs. 0 and an overall complication rate of 26% vs. 44%, respectively. In patients >70 years, pneumonectomy and sleeve lobectomy resulted in a 30-day mortality of 15% vs. 0 and an overall complication rate of 23% vs. 32%. In both age groups, pneumonectomy was associated with more airway complications (NS) and a significantly higher postoperative loss of FEV(1) than sleeve lobectomy (P<0.0001, P<0.03). Age per se did not influence the loss of FEV(1) and DLCO for a given type of resection. Sleeve lobectomy may have a therapeutic advantage over pneumonectomy in the postoperative course of elderly patients.     

Early post-pneumonectomy complications in the elderly.

OBJECTIVE: The surgical treatment of non-small cell lung cancer (NSCLC) in elderly patients presents a serious challenge to thoracic surgeons. As there is considerable divergence of opinion about both the mortality and morbidity rates, it is important to set guidelines for proper patient selection. METHODS: Early post-operative complications in 42 patients aged over 70 years who had undergone pneumonectomy because of NSCLC (Group I) were analyzed. The control group (Group II) consisted of 48 patients, also aged over 70 years, but who had undergone lobectomy or wedge resections. In both groups, the pre-operative conditions and 30-day morbidity and mortality were evaluated. RESULTS: Postoperative complications occurred significantly more frequently in pneumonectomy patients (78.5%) than in Group II (58%). Transient or long-standing arrhythmias were noted in 20 patients (47.6%) from Group I and in 17 (35.4%) from Group II. Pulmonary complications occurred in 17 patients (40.4%) from Group I and 16 (33.3%) from Group II. The most important factors contributing to post-operative complications in pneumonectomy patients were performance status (WHO), chronic obstructive pulmonary disease (COPD) and elevated level of blood urea nitrogen (BUN). The highest impact on early mortality in pneumonectomy patients was exerted by COPD, arterial hypertension, formation of broncho-pleural fistula (BPF), the need for re-thoracotomy and high level of BUN. CONCLUSIONS: (1) Pneumonectomy in patients over the age of 70 carries a considerable risk of severe post-operative complications and death, when compared to patients with less extensive pulmonary resections. (2) Elderly patients with impaired Performance Status (WHO 2 or more) and co-existing arterial hypertension, COPD and elevated level of BUN should be considered for pneumonectomy very carefully and cautiously.     

The Surgical Treatment of Breast Cancer in the Elderly: A Single Institution Comparative Review of 5235 Patients with 1028 Patients ≥70 years

Abstract: As the wave of the baby boomers shifts the age demographic of patients, the current surgical management of breast cancer in elderly women (≥70 years of age) becomes relevant because deviation from standard treatment often occurs in this group. The purpose of this study was to determine the operative mortality when treated with standard surgical procedures and to investigate trends in the surgical management of breast cancer in the elderly. A total of 5,235 patients undergoing either mastectomy or breast conservation surgery (BCS) for invasive and ductal carcinoma in situ (DCIS) were identified in a retrospective review of a prospectively accrued data base between the years of 1994 and 2007 at the Moffitt Cancer Center. Of the 5,235 patients, 1,028 (20%) patients were ≥70 years of age. The 30‐day and 90‐day mortality in the elderly group (age ≥70 years) was 0.2% (95% CI 0.02–0.7%) and 0.7% (95% CI 0.3–1.4%), respectively. The 30‐day and 90‐day mortality among patients <70 years was 0 and 0.05% (2 of 4,207 patients) (95% CI 0.005–0.2), respectively. BCS rates for invasive carcinomas were the highest for patients between 40 and 70 years of age, whereas the mastectomy rates were higher among patients <40 years of age (53%). Elderly women were as likely as women <40 years to have BCS for invasive carcinoma (OR 1.1, 95% CI 0.8–1.5), but more likely to have BCS for DCIS (OR 1.9, 95% CI 1.1–3.3). Surgical mortality in elderly women treated for breast cancer was extremely low and was related to the extent of surgery performed. Breast cancer treatment differed by age groups.     

Outcome after lung cancer surgery. Factors predicting early mortality and major morbidity.

OBJECTIVE: This study was undertaken to assess mortality, complications and major morbidity during the first 30 days after lung cancer surgery and to estimate the significance of presurgical risk factors. METHODS: The study was based on all patients referred for surgery for primary lung cancer from 1 January 1987 to 1 September 1999. There were in total 616 patients with primary lung cancer. Three-hundred and ninety-four were men and 222 women. Postoperative events studied were divided into major and minor complications or death during the first 30 days after surgery. The significance of risk factors for an adverse outcome (defined as death or major complication in the first 30 days postoperatively) was assessed by uni- and multivariate logistic regression analyses. RESULTS: During the study period an increasing number of women and of patients older than 70 years underwent surgery. Overall 30-day mortality was 2.9, 0.6% after single lobectomy and 5.7% after pneumonectomy. Major complications occurred in 54 patients (8.8%). Fifty-eight patients (9.5%) had an adverse outcome during the first 30 days. Male gender, smoker, FEV(1)< or =70% of expected value, squamous cell carcinoma and pneumonectomy were risk factors predicting adverse outcome in the univariate model. Pneumonectomy and FEV(1)< or =70%, were the only independently significant factors for adverse outcome. Only pneumonectomy was independently associated with an increased risk for early death. CONCLUSION: Our results show low mortality and morbidity after lung cancer surgery. However, patients with reduced lung capacity and those undergoing pneumonectomy should be treated with great care, as they run a considerable risk of major complications or death during the first 30 days postoperatively. Older age (>70 years) does not appear to be a contraindication to lung cancer surgery, but patients in this group should undergo careful preoperative evaluation.     

Operative complications and early mortality after induction therapy for lung cancer.

OBJECTIVE: Induction therapy for advanced lung cancer allows improvement of completeness of resection and survival. However, predictive risk factors for postoperative complications and early mortality remain controversial. We report our 14-year experience with this combined approach. METHODS: One hundred and thirty-nine patients (100 males and 39 females) underwent induction therapy and surgery for stage IIIA and B lung cancer. The mean age was 58.4+/-7.7 years. We retrospectively collected demographic data, preoperative functional parameters, type of operation, associated disorders, staging, induction regimen (chemotherapy alone or associated with radiotherapy). Univariate and multivariate analyses were performed to identify predictors of postoperative complications and early mortality. RESULTS: One hundred and nine patients received chemotherapy (mainly based on cisplatin and gemcitabine) and 30 received chemoradiotherapy (median dose 50Gy). Complications developed in 49 patients (35%). The most frequent was persistent air leakage (23-30% of the lobectomies), followed by cardiac complications, respiratory failure, and infections. Five patients (3.5%) died in the postoperative period and four of them had received pneumonectomy (mortality for pneumonectomy: 12.5%). The statistical analysis demonstrated that only pneumonectomy was associated with an increased mortality risk with no differences between intra- and extrapericardial dissection or right and left pneumonectomy. CONCLUSIONS: Induction therapy seems to be associated with an increased incidence of air leakage; the risk of other complications is acceptable. Pneumonectomy is associated with an increased risk of mortality and should be performed in selected patients.     

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.     

Factors associated with in-hospital complications and long-term implications of these complications in elderly patients undergoing endovascular aneurysm repair

ObjectivePerioperative complications in elderly patients undergoing endovascular aneurysm repair (EVAR) occur frequently. Although perioperative mortality has been well-described in the elderly patient population, factors associated with in-hospital complications and their impact on long-term survival remain poorly characterized.MethodsWe identified all patients undergoing elective EVAR for infrarenal AAA within the Vascular Quality Initiative registry (2003-2018) and compared in-hospital complication rates between elderly (age ≥75) and nonelderly patients (<75). We used logistic regression to identify independent factors associated with in-hospital complications, whereas Kaplan-Meier analysis and Cox proportional hazards models were used to determine associations between complications and long-term survival. To assess the effect of complications on early and late survival, we stratified survival periods into the first 30 days after discharge, and between 1 and 6 months, 7 and 12 months, and 1 and 8 years after the index procedure. To investigate the implications of in-hospital morbidity on long-term outcomes, we estimated the adjusted population-attributable fractions of individual complications on both perioperative and long-term survival.ResultsWe identified 17,156 elderly patients and 19,922 nonelderly patients. Elderly patients experienced higher complication rates compared with nonelderly patients (17% vs 10%; P < .001). The factors with the strongest associations with morbidity in elderly patients were anemia (odds ratio [OR], 2.4; 95% confidence interval [CI], 2.2-2.6), female gender (OR, 1.9; 95% CI, 1.7-2.1), and large AAA diameter (OR, 1.7; 95% CI, 1.6-1.9). Patients with any in-hospital complication had lower unadjusted survival estimates than patients without complications at 1 year (83% vs 95%; P < .001), 5 years (66% vs 80%; P < .001), and 8 years (60% vs 72%; P < .001). After risk adjustment, in-hospital complications were independently associated with higher mortality, although the association attenuated over time (first month after discharge: hazard ratio [HR], 5.9; 95% CI, 3.9-9.1; 1-6 months after the procedure: HR, 2.1; 95% CI, 1.7-2.7; P < .001; 7-12 months after the procedure: HR, 1.5; 95% CI, 1.1-1.9; 1-8 years after the procedure: HR, 1.2; 95% CI, 1.01-1.3). Of all deaths occurring within 8 years after procedure, 9.5% were independently associated with in-hospital complications. Complications with the greatest impact on long-term mortality were renal dysfunction (2.4%), blood transfusion (3.4%), and reintubations (2.4%).ConclusionsElderly patients are at higher risk for in-hospital complications after EVAR. These in-hospital complications have a significant impact on both short- and long-term survival. To further improve the delivery of EVAR care nationally, quality improvement efforts should be focused on preventing postoperative morbidity in elderly patients, as well as refining out of hospital surveillance strategies for subjects who experience in-hospital complications to improve overall survival.     

Factors related to outcome after pneumonectomy: retrospective study of 62 patients.

OBJECTIVE: To find out which risk factors affect outcome after pneumonectomy. DESIGN: Retrospective study. SETTING: Teaching hospital, The Netherlands. SUBJECTS: 62 patients who were treated for bronchial cancer by pneumonectomy between 1984 and 1995. MAIN OUTCOME MEASURE: Hospital mortality and postoperative complications. RESULTS: Hospital mortality increased with age, being 5/51 (10%) in the 40-69 age group and 4/11 (36%) in patients aged 70 or more. In the American Society of Anesthesiologists (ASA) class I group hospital mortality was 8% (2/26), in class II 12% (3/26) and in class III 40% (4/10). Hospital mortality was highest when the FEV1:FVC-ratio was below 55%. Cardiac arrhythmias developed in 8 (13%), early bronchopleural fistulas in 7 (11%), and postpneumonectomy syndrome in 5 (8%). These major complications had a high mortality. CONCLUSION: Respiratory function, ASA class, and age over 70 years are the main prognostic factors for hospital morbidity and mortality after pneumonectomy.     

Is the excision surgery of bronchial cancer in patients over 70 years of age justified?

The retrospective analysis of 331 files relating to primary bronchial cancer shows that 30% of the patients are 70 years old or over. This patient group is compared to younger subjects who were operated during the same period. For this surgical series, the disease studied is the same whichever the age (detection conditions, excision types, TNM classification). Mortality for excision is comparable (5.1% vs 8.2%), but the type of mortal complications differs according to the age. Our analysis allows isolating two factors of risk (cardiovascular defects and obstructive chronic respiratory failure). Provided that a pre-operation rigorous selection of the patients over 70 years has been made, pneumonectomy does not seem more serious than lobectomy (mortality 3.7% vs 10.3%). For identical stages, remote survival after excision can be compared to that of operated patients under 70 years old. Excision beyond 70 years old seems justified provided that: a selection of patients, from which subjects having major defects (cardiovascular and respiratory) should be excluded, is carried out by appreciating physiological age and not actual age, a pre-operation respiratory preparation is performed, a careful operating technique which allows avoiding surgical complications is used, a peri-operating assistance is provided.     

Hospital mortality and long-term survival after pulmonary resection in the elderly

We have studied the hospital mortality and long-term survival in two groups of patients: those between 50 and 69 years of age (group 1, n = 136) and those older than 70 years of age (group 2, n = 43). The two groups were similar in terms of the distribution of histological type and postsurgical staging. The patients were treated by either lobectomy or pneumonectomy; the lobectomy rate was similar in both groups: 61% and 51% (not significant). Hospital mortality for group 1 was 4.4% and for group 2, 6.9%. Mortality was higher in both groups after pneumonectomy compared with lobectomy, but this was not significant (group 1, 6.2% versus 1.9%; group 2, 9.1% versus 4.7%). Hospital mortality after pulmonary resection was greater in the elderly, but this was not significant (lobectomy: 1.9% [group 1] versus 4.7% [group 2]; pneumonectomy: 6.2% [group 1] versus 9.1% [group 2]. The overall long-term survival at 2 and 4 years was 62.3% and 50.0% for group 1 and 72.5% and 66.6% for group 2. We suggest that the operative risk in the elderly is not prohibitive and the long-term results are acceptable. Patients should not be denied operation on the basis of age alone.     

Long-term results in the elderly following pulmonary resection for non-small cell lung carcinoma

The long-term results of 647 patients undergoing pulmonary resection for non-small cell lung carcinoma (NSCLC) between 1980–1988 were reviewed. One hundred forty-five (22%) were elderly patients (70 years or more, group 1), with a mean age of 72.3 years (70–81) and the other 502 (18%) were younger (69 years or less, group 2) with a mean age of 61.4 (40–69) years. The male to female ratio was 4:1 in group 1 and 3:1 in group 2. The number of patients in group 2 (n = 234, 47%) who underwent pneumonectomy was significantly greater (P < 0.01), compared to group 1 (n = 47,32%). Cardiopulmonary complications were more frequently observed in group 1 (19.3%) than in group 2 (7.4%), P < 0.05. Although cardiac complications (i.e. arrhythmias) were more common in the elderly group, pulmonary complications (retained secretions, atelectasis) occurred more commonly in the younger group. The overall hospital mortality in group 1 and group 2 was 8.9% and 5.3%, respectively (NS), and mortality following pneumonectomy in group 1 (10.6%) was similar to that of group 2 (7.6%) (NS). The 2- and 5-year overall actuarial survival rates were 61% and 30% in group 1 and 57% and 37% in group 2 (NS). Superior survival was achieved in patients in stage I of the disease in both groups. Cell type was not a determinant of long-term survival differences between the groups whereas type of operation (lobectomy) and sex (female) were. Carcinoma of the lung in the elderly patient may be treated successfully, achieving a low hospital mortality figure and respectable long-term survival though the patients seem to suffer from more complications.     

Are we undertreating rectal cancer in the elderly? An epidemiologic study

OBJECTIVE: To better understand the reasons for decreased survival rates in elderly patients with rectal cancer by performing an epidemiologic evaluation of age-related differences in treatment and survival. SUMMARY BACKGROUND DATA: The incidence of rectal cancer increases with older age, and localized disease can be curatively treated with stage-appropriate radical surgery. However, older patients have been noted to experience decreased survival. METHODS: Patients with localized rectal adenocarcinoma were identified in the Surveillance, Epidemiology, and End Results database (1991-2002). Cancer-specific survival by age, sex, surgery type, tumor grade, lymph node status, and use of radiation therapy was evaluated using univariate and multivariate regression analysis. RESULTS: We identified 21,390 patients who met the selection criteria. The median age was 68 years. Each half-decade increase in age > or =70 years was associated with a 37% increase in the relative risk (RR) for cancer-related mortality (RR = 1.37; 95% confidence interval [CI], 1.33-1.42); decreased receipt of cancer-directed surgery (odds ratio [OR] = 0.56; 95% CI, 0.36-0.63); more local excision and less radical surgery (OR = 0.76; 95% CI, 0.72-0.81); less radiotherapy (OR = 0.64; 95% CI, 0.61-0.67); and greater likelihood of N0 pathologic stage classification (OR = 1.10; 95% CI, 1.05-1.15) (P < 0.0001 for each factor). The effect of age on cancer-specific mortality persisted in multivariate analysis with each half-decade increase in age > or =70 years resulting in a 31% increase in cancer-specific mortality (RR = 1.31; 95% CI, 1.25-1.36; P < 0.0001). CONCLUSIONS: In elderly patients, rectal cancer is characterized by decreased cancer-related survival rates that are associated with less aggressive treatment overall and decreased disease stages at presentation. Investigation into the reasons for these treatment differences may help to define interventions to improve cancer outcomes.     

Long-term outcomes and risk factor analysis after pneumonectomy for active and sequela forms of pulmonary tuberculosis.

OBJECTIVE: The prevalence of pulmonary tuberculosis remains high in several areas of the world, and pneumonectomy is often necessary to treat the disease. We retrospectively analyzed the morbidities, mortalities, and long-term outcomes after pneumonectomy for the treatment of active tuberculosis or its sequelae. MATERIALS AND METHODS: Between 1981 and 2001, 94 patients underwent either pneumonectomy or pleuropneumonectomy for the treatment of tuberculosis. The patients included 44 males and 50 females and the mean age was 40 (16-68) years. The pathology included destroyed lung in 80, main bronchus stenosis in ten, and both lesions in four. Surgical procedures performed were pneumonectomy in 47, pleuropneumonectomy in 43, and completion pneumonectomy in four. RESULTS: One patient died postoperatively due to empyema. Twenty-three complications occurred in 20 patients: empyema in 15 (including seven bronchopleural fistulae), wound infections in five, and other complications in three. Univariate analysis revealed the presence of empyema, pleuropneumonectomy, prolonged operation time, old age, and intraoperative contamination as risk factors of postpneumonectomy empyema; it also showed that low preoperative FEV(1) and postoperative persistent positive sputum AFB were risk factors of bronchopleural fistula. In multivariate analysis, old age and low preoperative FEV(1) were risk factors of empyema while low preoperative FEV(1), positive sputum acid-fast bacilli, and the presence of aspergilloma were risk factors of bronchopleural fistula. There were 12 late deaths. Actuarial 5- and 10-year survival rates were 94+/-3% and 87+/-4%, respectively. CONCLUSION: Pneumonectomy could be performed with acceptable mortality and morbidity, and could achieve satisfactory long-term survival for the treatment of tuberculosis. In patients with risk factors, special care is recommended to prevent postoperative empyema or bronchopleural fistula.     

Esophageal resection in elderly esophageal carcinoma patients: improvement in postoperative complications

BACKGROUND: Advanced age is considered to be a relative contraindication for radical esophagectomy with a three-field lymph node dissection. METHODS: Preoperative risks, postoperative morbidity and mortality, and long-term survival in 55 elderly patients (> or =70 years) who had undergone extensive esophagectomy for esophageal carcinoma were compared with those of 149 younger patients (<70 years). RESULTS: Elderly patients had worse preoperative cardiopulmonary function and had more frequent postoperative cardiopulmonary complications compared with younger patients (p < 0.05). The postoperative death rate was not statistically different between the elderly (10.9%) and younger groups (5.4%). When the study period was divided into an early and a late phase, the postoperative death rate dropped significantly (p < 0.05) in recent years (1.4%) when compared with the previous era (10.0%). The overall survival rates were not different between elderly and younger patients. CONCLUSIONS: Preoperative cardiopulmonary risk factors and postoperative complications after esophagectomy were more frequently noticed in elderly patients than in younger patients. A dramatic improvement in postoperative death was noticed in recent years. The long-term survival of elderly patients after extended esophagectomy was almost similar to that in younger patients.     

Pancreatic resection in elderly patients: should it be denied?

Background

Surgery remains the only potential curative therapy for pancreatic cancer, but compromised physiological reserve and comorbidities may deny pancreatic resection from elderly patients.

Methods

The medical records of all patients who underwent pancreatic resection at our institution (2005–2012) were retrospectively reviewed. Postoperative and long-term outcomes were compared between patients with cutoff age of 70 years.

Results

A total of 228 (66 %) and 116 (34 %) patients were <70 and ≥70 years, respectively. Elderly group had worse ASA scores (P?<?0.0001) with higher rates of invasive malignant pathologies (75 vs. 67 %, P?=?0.14), mainly pancreatic ductal adenocarcinoma (58.6 vs. 44.7 %, P?=?0.01). The most common type of resection was pancreaticoduodenectomy (PD) (59 %), followed by distal pancreatectomy (19.8 %). Mean hospital stay was comparable. Elderly patients had less grade ≥IIIb postoperative complications (12 vs. 20.1 %; P?=?0.04) and higher postoperative mortality rates (12.9 vs. 3.9 %; P?=?0.04). In multivariable Cox proportional hazards model for postoperative mortality, age ≥70 years (HR, 3.5; 95 % CI, 1.3–9.3), pancreaticoduodenectomy (HR, 12.6; 95 % CI, 1.6–96), and intraoperative blood loss were significant (P?=?0.012; P?=?0.015, and P?=?0.005, respectively). The overall 5-year survival rates for all patients, for patients aged <70 and ≥70 years were 56, 55, and 41 %, respectively (P?=?0.003).

Conclusions

Elderly patients are at higher risk of mortality after pancreatic resection than usually reported case series. Nonetheless, elderly patients can undergo pancreatic resection with acceptable 5-year survival results. Our results contribute for a better, informed decision-making for elderly patients and their family.     

Surgical results of stage I non-small cell lung cancer: comparison between elderly and younger patients.

OBJECTIVE: The aim of this study was to evaluate the overall cancer-related survival in younger and elderly (over 70 years old) patients with stage I non-small cell lung cancer (NSCLC) together with prognostic factors in the elderly. METHODS: The patient records of 797 patients who underwent surgery for stage I NSCLC were analyzed retrospectively. A total of 132 patients were over 70 years old. The clinical variables and overall cancer-related survival were compared between two groups. An analysis was performed to determine the risk factors that influenced the survival of elderly patients. Variables analyzed included sex, presence of symptoms, operative procedure, histopathology, size of tumor and tumor classification. RESULTS: Between the two groups, the nature of the operation performed (pneumonectomy or not) and the presence of symptoms reached statistical significance (P<0.001). Overall 5- and 10-year survival rates were 64.5% and 53.68% in younger patients and 58.23% and 52.24% in the elderly. There was no significant difference in survival between the groups (P=0.35). The only significant prognostic factor in the elderly patients was the size of the tumor in the multivariate analysis (P=0.0442, relative risk 2.28 (1.02-5.10 95% CI)). CONCLUSIONS: Surgical resection for stage I NSCLC in elderly patients over the age of 70 years results in a comparable overall cancer-related survival to that evident in younger patients. The size of the tumor is the only significant factor to influence the survival of elderly patients. Continued careful selection of elderly patients for surgical resection is important for acceptable operative results.     

Prognostic significance of postoperative in-hospital complications in elderly patients. I. Long-term survival

To determine the impact of in-hospital postoperative complications on long-term survival, we prospectively studied consecutive patients > or = 70 yr of age undergoing noncardiac surgery. Potential clinical risk factors were measured and evaluated for their association with the occurrence of long-term postoperative mortality. Long-term survival was determined by using the Kaplan-Meier method. Multivariate correlates of survival were analyzed with the Cox proportional hazards model. The survival of the study group was also compared with the age- and gender-matched general United States population. Five hundred seventeen patients who survived the initial hospitalization were studied. The mean follow-up duration was 28.6 +/- 12.8 mo. One hundred sixty-four of 517 patients (31.7%) were deceased at the time of follow-up. A history of cancer (hazard ratio [HR] 2.44, 95% confidence interval [CI] 1.78-3.38, P < 0.0001), ASA physical status >II (HR 2.27, 95% CI 1.61-3.21, P < 0.0001), neurologic disease (HR 1.59, 95% CI 1.13-2.24, P = 0.008), age (HR 1.42 per decade, 95% CI 1.11-1.81, P = 0.005), postoperative pulmonary complications (HR 2.41, 95% CI 1.30-4.48, P = 0.005), and renal complications (HR 6.07, 95% CI 2.23-16.52, P < 0.0001) were significant independent predictors of decreased long-term survival. Compared with the United States population, patients with complications had a greater increase in mortality risk in the first 3 mo after surgery (HR 7.3 versus general population) than those without complications (HR 2.9, P = 0.023). An effort to improve perioperative care delivery to elderly surgical patients must include measures to minimize in-hospital postoperative complications, particularly those involving the pulmonary and renal systems.     

The role of cardiac morbidity in short- and long-term mortality in injured older patients who survive initial resuscitation

BACKGROUND: Elderly patients are an increasingly larger group of injured trauma care patients. Comorbidities influence outcome. Little is known of short- and long-term mortality in the elderly who survive initial resuscitation. METHODS: Short- and long-term mortality was retrospectively analyzed in 363 consecutively injured patients (Injury severity score >15) surviving more than 3 days after admission to a level 1 trauma center (including 197 patients >60 years). Cardiac morbidity was the focus. RESULTS: Survival to hospital discharge was similar comparing older patients with the entire group. Mortality increased incrementally with age. In older patients, cardiac morbidity was observed in 28% (fatal in 7); 2-year mortality was 36% (older group) and 60% (patients sustaining cardiac complications). Most elderly (80%) were discharged to long-term care. CONCLUSIONS: Elderly who survive initial resuscitation are as likely to survive to discharge as younger patients, but long-term survival is significantly lower as age increases. Cardiac morbidity is associated with higher long-term mortality. Most elderly are discharged to long-term care.     

Predicting pulmonary complications after pneumonectomy for lung cancer.

OBJECTIVES: Patients undergoing pneumonectomy for lung cancer are thought to be at high risk for the development of postoperative pulmonary complications (PC) and these complications are associated with high mortality rates. The purpose of this study was to identify independent factors associated with increased risk for the development of postoperative PC after pneumonectomy for lung cancer, and to assess the usefulness of predicted pulmonary function to identify high risk patients and other adverse outcomes. PATIENTS AND METHODS: We reviewed retrospectively 242 patients undergoing pneumonectomy for lung cancer during a 12-year period. Perioperative data (clinical, pulmonary function test, and surgical) were recorded to identify risk factors of PC by univariate and multivariate analyses. RESULTS: Overall mortality and morbidity rates were 5.4 and 59%, respectively. Thirty-four patients (14%) developed PC (acute respiratory failure, ARF = 8.7%, reintubation = 5.4%, pneumonia = 3.3%, atelectasis = 2.9%, postpneumonectomy pulmonary edema = 2.5%, mechanical ventilation more than 24 h = 1.2%, pneumothorax = 0.8%). Patients with surgical (P < 0.001), cardiac (P < 0.001) and other complications (P < 0.01) had higher incidence of PC than those without postoperative complications. Intensive care unit stay (53 +/- 39 h vs. 35 +/- 19 h; P < 0.001) and hospital stay (18 +/- 11 days vs. 12 +/- 7 days; P < 0.001) was significantly longer in patients with PC. The mortality rate associated with PC was 35.5% (P < 0.001). By univariate analysis, it was found that older patients (P = 0.007), chronic obstructive pulmonary disease (COPD) (P = 0.023), heart disease (P = 0.019), no previous record of chest physiotherapy (P = 0.008), poor predicted postoperative forced expiratory volume in 1s (ppo-FEV1) (P = 0.001), and prolonged anesthetic time (P < 0.001) were related with higher risk of PC. In the multiple logistic regression model, the anesthetic time (minutes; odds ratio, OR = 1.012), ppo-FEV1 (ml/s; OR = 0.998), heart disease (OR = 2.703), no previous record of previous chest physiotherapy (OR = 2.639), and COPD (OR = 2.277) were independent risk factors of PC. CONCLUSIONS: PC after pneumonectomy are associated with high mortality rates. Careful attention must be paid to patients with COPD and heart disease. Our results confirm the relevance of previous chest physiotherapy and the importance of the length of the surgical procedure to minimize the incidence of PC. The predicted pulmonary function (ppo-FEV1) may be useful to identify high risk patients for PC development and adverse outcomes.
