Frailty Is Associated With Adverse Postoperative Outcomes After Lung Cancer Resection.

ABSTRACT:

Introduction

Frailty is an important predictor of outcomes after noncardiac surgery. The 5-factor Modified Frailty Index (mFI-5) is a recently developed frailty metric that has not been adequately evaluated in relation to surgical therapy for lung cancer. We evaluated whether the mFI-5 is predictive of clinical and administrative outcomes after anatomical lung resection for cancer.

Methods

Data in the Society of Thoracic Surgeons Database were used to evaluate the relationship of mFI-5 to outcomes of patients undergoing elective anatomical lung resection for cancer from 2015 to 2018 using logistic regression analyses. Results were compared with validated risk predictors, including the American Society of Anesthesiologists Physical Status Classification and the Charlson Comorbidity Index.

Results

The mFI-5 score could be calculated for 36,587 patients. On univariate analyses, mFI-5 was significantly associated with all clinical and administrative outcomes in an incremental pattern (p < 0.0001 for each). On multivariate analyses, mFI-5 was significantly associated in an incremental pattern with 13 of 15 postoperative complication and administrative outcome categories; the exceptions were cardiovascular complications and 30-day mortality. The overall performance of the frailty metric mFI-5 was similar to that of the American Society of Anesthesiologists and the Charlson Comorbidity Index.

Conclusions

The mFI-5 is independently predictive of almost all outcomes after lung resection for cancer. It can be calculated from data typically collected for thoracic surgical patients. Assessment of surgical candidates using mFI-5 may be useful in risk prediction and may identify patients who would benefit from mitigation of increased surgical risk related to frailty.

Project description:ObjectiveTo determine the benefits of preoperative breathing exercises on hospital length of stay (LOS), pneumonia, postoperative pulmonary complications (PPC), 6-minute walk distance (6MWD), forced expiratory volume in 1 second (FEV1), and health-related quality of life (HRQOL) in patients undergoing surgical lung cancer resection.Data sourcesPubMed, EMBASE, Web of Science Core Collection, and Cochrane Central Register of Controlled Trials were comprehensively searched from inception to March 2021.Study selectionOnly studies including preoperative inspiratory muscle training (IMT) and/or breathing exercises compared with a nontraining control group were included. The meta-analysis was done using Cochrane software for multiple variables including LOS, pneumonia, PPC, 6MWD, FEV1, mortality, and HRQOL.Data extractionTwo authors extracted the data of the selected studies. The primary outcomes were LOS and PPC.Data synthesisA total of 10 studies were included in this meta-analysis, 8 of which had both IMT and aerobic exercise. Pooled data for patients who performed preoperative breathing exercises, compared with controls, demonstrated a decrease in LOS with a pooled mean difference of -3.44 days (95% confidence interval [CI], -4.14 to -2.75; P<.01). Subgroup analysis also demonstrated that LOS was further reduced when breathing exercises were combined with aerobic exercise (χ2, 4.85; P=.03). Preoperative breathing exercises reduce pneumonia and PPCs with an odds ratio of 0.37 (95% CI, 0.18-0.75; P<.01) and 0.37 (95% CI, 0.21-0.65; P<.01), respectively. An increase in 6MWD of 20.2 meters was noted in those performing breathing exercises (95% CI, 9.12-31.21; P<.01). No significant differences were noted in FEV1, mortality, or HRQOL.ConclusionsPreoperative breathing exercises reduced LOS, PPC, and pneumonia and potentially improved 6MWD in patients undergoing surgical lung cancer resection. Breathing exercises in combination with aerobic exercise yielded greater reductions in LOS. Randomized controlled trials are needed to test the feasibility of introducing a preoperative breathing exercise program in this patient population.

Project description:Background To investigate postoperative temporary consequences of the enrolled patients with lung adenocarcinoma. Patients and Methods We analyzed the clinical data of patients with lung adenocarcinoma admitted by the same surgical team of Peking Union Medical College Hospital (PUMCH) from July 2019 to December 2019. Statistical methods including propensity score matching (PSM) analysis was used to analyze the differences among them. Results A total of 108 patients were enrolled, including 50 patients with sublobar resection and 58 patients with lobectomy. Before PSM, there were statistically significant differences in age (p=0.015), hospitalization costs (p=0.042), lymphadenectomy (p=0.000), pathological staging (p=0.000), number of lymph nodes removed (p=0.000), number of positive lymph nodes (p=0.034), chest drainage duration (p=0.000), total chest drainage (p=0.000), length of postoperative hospital stays (p=0.000), postoperative D-dimer level (p=0.030) and perioperative lymphocyte margin (LM) (p=0.003) between sublobar resection and lobectomy. After PSM, there were statistical differences in number of lymph nodes removed (p=0.000), chest drainage duration (p=0.031) and total chest drainage (p=0.002) between sublobar resection and lobectomy. Whether with PSM analysis or not, there were no significant differences in other blood test results, such as inflammation indicators, postoperative neutrophil-lymphocyte ratio (NLR), albumin level, perioperative activity of daily living (ADL) scale scoring margin, complications, postoperative admission to intensive care unit (ICU) and readmission within 30 days. NLR was associated with total chest drainage (p=0.000), length of postoperative hospital stays (p=0.000), postoperative D-dimer level (p=0.050) and ADL scale scoring margin (p=0.003) between sublobar resection and lobectomy. Conclusion Sublobar resection, including wedge resection and segmentectomy, was as safe and feasible as lobectomy in our study, and they shared similar short-term outcomes. Postoperative NLR could be used to detect the clinical outcomes of patients. Secondary resectability of pulmonary function (SRPF) should be the main purpose of sublobar resection.
