Risk stratification of postoperative pulmonary complications in elderly patients undergoing lung cancer resection: a propensity score-matched study.

ABSTRACT:

Background

In China, lung cancer mainly affects the elderly population. Surgery remains the standard treatment for lung cancer in elderly patients, however, postoperative pulmonary complications (PPCs) are major contributors to morbidity and mortality following lung resection. This study aimed to identify perioperative predictors of PPCs among elderly patients undergoing pulmonary resection for lung cancer to provide evidence for better prevention and intervention for PPCs.

Methods

A retrospective study was conducted with 456 patients (age >65 years) undergoing pulmonary resection for lung cancer in Yunnan, China from January 2016 to March 2019. Propensity score matching (PSM) was performed to compare preoperative data and clinical characteristics between the PPC and non-PPC groups, followed by binary logistic regression to evaluate predictors of PPCs.

Results

Pulmonary complications occurred in 142/456 (31.1%) patients age >65 years, with pneumonia being the most common event (21.7%). Both PSM and binary logistic regression analysis identified American Society of Anesthesiologists (ASA) class ConclusionsPPCs following lung cancer resection in elderly patients were associated with a higher ASA classification and open thoracotomy. An adequate and comprehensive evaluation of the operative strategies and enhanced recovery methods should be implemented among elderly patients undergoing lung resection with an ASA class > II or those undergoing an open thoracotomy to help prevent the occurrence of PPCs.

Project description:ObjectivesTo assess the prevalence of postoperative pulmonary complications (PPCs), the perioperative factors associated with PPCs, and the association of PPCs with postoperative outcomes in ovarian cancer patients undergoing cytoreductive surgery.MethodsA retrospective analysis was conducted on patients who underwent cytoreductive surgery in our hospital, between September 2017 and January 2021, and patient medical records were reviewed to collect relevant clinical information. Univariable and multivariable analyses were used to identify significant risk factors for PPCs. Analysis of the association of PPCs with postoperative outcomes, mortality and 30-day readmission, was undertaken utilizing propensity score-matched controls and multivariable logistic regression model.ResultsFinal analysis was performed with 268 ovarian cancer patients after cytoreductive surgery, among whom the incidence of PPCs was 26.9%, and the most frequent pulmonary complication was pleural effusion. According to the multivariate analysis, the intraoperative fluid infusion volume (L) (odds ratio (OR) 1.34; 95% confidence intervals (CI) 1.01-1.77; P = 0.040), diameter size of diaphragmatic resection (cm) (OR 1.16; 95% CI 1.06-1.28; P = 0.002), and surgical complexity scores (OR 1.26; 95% CI 1.13-1.42; P < 0.001) were significantly associated with the development of PPCs. The multivariable logistic regression analyses with propensity-matched controls demonstrated that the occurrence of PPCs significantly increased the risk of 30-day readmission (OR 6.01; 95% CI 1.12-32.40; P = 0.037) and did not significantly affect inpatient mortality.ConclusionOvarian cancer patients undergoing cytoreductive surgery, especially those with diaphragmatic resection or higher surgical complexity scores, represent a high-risk population for PPCs. In addition, goal-directed fluid therapy is vital to reducing the occurrence of PPCs in patients at risk. PPCs were not associated with in-hospital mortality but were significantly associated with an increased risk of 30-day readmission after cytoreductive surgery.

Project description:BackgroundThere is no consensus regarding the superiority of volatile or total intravenous anesthesia (TIVA) in reducing the incidence of postoperative pulmonary complications (PPCs) after lung resection surgery (LRS). Thus, the aim of this study was to investigate the different anesthetic regimens and the incidence of PPCs in patients who underwent LRS. We hypothesized that TIVA is associated with a lower incidence of PPCs than volatile anesthesia.MethodsThis was a retrospective cohort study of patients who underwent LRS at Taipei Veterans General Hospital between January 2016 and December 2020. The patients' charts were reviewed and data on patient characteristics, perioperative features, and postoperative outcomes were extracted and analyzed. The patients were categorized into TIVA or volatile anesthesia groups and their clinical data were compared. Propensity score matching was performed to reduce potential selection bias. The primary outcome was the incidence of PPCs, whereas the secondary outcomes were the incidences of other postoperative events, such as length of hospital stay (LOS) and postoperative nausea and vomiting (PONV).ResultsA total of 392 patients each were included in the TIVA and volatile anesthesia groups. There was no statistically significant difference in the incidence of PPCs between the volatile anesthesia and TIVA groups. The TIVA group had a shorter LOS (p < 0.001) and a lower incidence of PONV than the volatile anesthesia group (4.6% in the TIVA group vs. 8.2% in the volatile anesthesia group; p = 0.041). However, there were no significant differences in reintubation, 30-day readmission, and re-operation rates between the two groups.ConclusionsThere was no significant difference between the incidence of PPCs in patients who underwent LRS under TIVA and that in patients who underwent LRS under volatile anesthesia. However, TIVA had shorter LOS and lower incidence of PONV which may be a better choice for maintenance of anesthesia in patients undergoing LRS.

Project description:ImportanceDistant recurrence following preoperative chemoradiotherapy and resection in patients with gastroesophageal adenocarcinoma is common. Adjuvant chemotherapy may improve survival.ObjectiveTo compare adjuvant chemotherapy with postoperative observation following preoperative chemoradiotherapy and resection in patients with gastroesophageal adenocarcinoma.Design, setting, and participantsPropensity score-matched analysis using the National Cancer Database. We included adult patients who received a diagnosis between 2006 and 2013 of clinical stage T1N1-3M0 or T2-4N0-3M0 adenocarcinoma of the distal esophagus or gastric cardia who were treated with preoperative chemoradiotherapy and curative-intent resection. Patients receiving adjuvant chemotherapy were matched by propensity score to patients undergoing postoperative observation.ExposuresAdjuvant chemotherapy and postoperative observation.Main outcomes and measuresOverall survival.ResultsWe identified 10 086 patients (8840 [88%] male; mean [SD] age, 61 [9.5] years), 9272 in the postoperative observation group and 814 in the adjuvant chemotherapy group. Patients receiving adjuvant chemotherapy were younger (18-54 years: 252 [31%] vs 1989 [21%]; P < .001) and were more likely to have advanced disease (ypT3/4: 458 [62%] vs 3531 [46%]; P < .001; ypN+: 572 [72%] vs 3428 [39%]; P < .001), as well as shorter postoperative inpatient stays (>2 weeks: 94 [13%] vs 1589 [20%]; P < .001). A total of 732 patients in the adjuvant chemotherapy group were matched by propensity score to 3660 patients in the postoperative observation group. Adjuvant chemotherapy was associated with improved overall survival compared with postoperative observation (median survival: 40 months; 95% CI, 36-46 months vs 34 months; 95% CI, 32-35 months; stratified log-rank P < .001; hazard ratio, 0.79; 95% CI, 0.72-0.88). Overall survival at 1, 3, and 5 years was 88%, 47%, and 34% in the observation group, and 94%, 54%, and 38% in the adjuvant chemotherapy group, respectively. Adjuvant chemotherapy was associated with a survival benefit compared with postoperative observation in most patient subgroups.Conclusions and relevanceFor patients with locally advanced gastroesophageal adenocarcinoma treated with preoperative chemoradiotherapy and resection, adjuvant chemotherapy was associated with improved overall survival. Our findings have important implications for the postoperative treatment of this patient group for which few data are available.

Project description:BackgroundThe patients undergoing laparoscopic radical colorectomy in many Chinese hospitals do not achieve high compliance with the ERAS (enhanced recovery programs after surgery) protocol.MethodsThe clinical data from 1,258 patients were collected and divided into the non-ERAS and incomplete ERAS groups.ResultsA total of 1,169 patients were screened for inclusion. After propensity score-matched analysis (PSM), 464 pairs of well-matched patients were generated for comparative study. Incomplete ERAS reduced the incidence of postoperative complications (p = 0.002), both mild (6.7% vs. 10.8%, p = 0.008) and severe (3.2% vs. 6.0%, p = 0.008). Statistically, incomplete ERAS reduced indirect surgical complications (27,5.8% vs. 59, 12.7) but not local complications (19,4.1% vs. 19, 4.1%). The subgroup analysis of postoperative complications revealed that all patients benefited from the incomplete ERAS protocol regardless of sex (male, p = 0.037, 11.9% vs. 17.9%; female, p = 0.010, 5.9% vs. 14.8%) or whether neoadjuvant chemotherapy was administered (neoadjuvant chemotherapy, p = 0.015, 7.4% vs. 24.5%; no neoadjuvant chemotherapy, p = 0.018, 10.2% vs. 15.8%). Younger patients (<60 year, p = 0.002, 7.6% vs. 17.5%) with a low BMI (<22.84, 9.4% vs. 21.1%, p < 0.001), smaller tumor size (<4.0 cm, 8.1% vs. 18.1%, p = 0.004), no fundamental diseases (8.8% vs. 17.0%, p = 0.007), a low ASA score (1/2, 9.7% vs. 16.3%, p = 0.004), proximal colon tumors (ascending/transverse colon, 12.2% vs. 24.3%, p = 0.027), poor (6.1% vs. 23.7%, p = 0.012)/moderate (10.3% vs. 15.3%, p = 0.034) tumor differentiation and no preoperative neoadjuvant radiotherapy (10.3% vs. 16.9%, p = 0.004) received more benefit from the incomplete ERAS protocol.ConclusionThe incomplete ERAS protocol decreased the incidence of postoperative complications, especially among younger patients (<60 year) with a low BMI (<22.84), smaller tumor size (<4.0 cm), no fundamental diseases, low ASA score (1/2), proximal colon tumors (ascending/transverse colon), poor/moderate differentiation and no preoperative neoadjuvant radiotherapy. ERAS should be recommended to as many patients as possible, although some will not exhibit high compliance. In the future, the core elements of ERAS need to be identified to improve the protocol.
