Minimally Invasive Lobectomy Is Associated With Lower Noncancer-specific Mortality in Elderly Patients: A Propensity Score Matched Competing Risks Analysis.

ABSTRACT: OBJECTIVE:To investigate cancer- and noncancer-specific mortality following lobectomy by minimally invasive surgery (MIS) versus open thoracotomy in elderly patients with nonsmall cell lung cancer (NSCLC). BACKGROUND:Two-thirds of patients with NSCLC are ?65 years of age. As age increases, the risk of competing events, such as noncancer death, also increases. METHODS:Elderly patients (?65 yrs of age) who have undergone curative-intent lobectomy for stage I-III NSCLC without induction therapy (2002-2013) were included (n=1,303). Of those, 607 patients had undergone MIS and 696 had undergone thoracotomy. Propensity-score matching was performed to identify pairs of thoracotomy and MIS patients with comparable clinical characteristics (eg, year of surgery, comorbidities, and pulmonary function). Association between surgical approach (MIS vs thoracotomy) and lung cancer-specific and noncancer-specific cumulative incidence of death (CID) was analyzed using competing risks approach. RESULTS:Following propensity score matching of patients who had undergone thoracotomy (n=338) versus MIS (n=338), MIS was associated with shorter length of stay (P <0.001), lower noncancer-specific 1-year mortality (P=0.027), and lower noncancer-specific CID (P=0.014) compared with thoracotomy; there was no difference in lung cancer-specific CID between surgical approaches. On multivariable analysis, thoracotomy was a significant risk factor for noncancer-specific death (subhazard ratio 2.45, 95% CI 1.18-5.06, P=0.016) independent of age, sex, and diffusion capacity of the lungs for carbon monoxide. CONCLUSION:In a propensity score-matched cohort, multivariable analysis has indicated that lobectomy performed by MIS is associated with lower incidence of noncancer-specific mortality compared with lobectomy performed by open thoracotomy in elderly patients with NSCLC.

Project description:Background:Whether the benefits of early prophylactic anticoagulation by low molecular weight heparin (LMWH) would outweigh its possible harms in patients after minimally invasive cardiac surgery (MICS) remains contentious. The aims of this study were to define the incidence of venous thromboembolism (VTE) and to assess whether early prophylactic anticoagulation by LMWH postoperatively was indeed effective in reducing VTE without increasing risk of complications after MICS. Methods:This investigation was a single-center, retrospective, propensity score-matched analysis study. A total of 473 patients underwent MICS, of whom 257 received prophylactic anticoagulation with LMWH (LMWH group) in the early postoperative period and 216 were not treated with LMWH (Control group). The main outcome measurements included the incidence of embolism events and major bleeding events, the volume of erythrocyte transfusion, the volume of drainage and the duration of drainage after MICS. In addition, the incidence of poor wound healing, the mechanical ventilation time, ICU stay time and postoperative hospitalization time were also documented. Results:There were fewer embolic events (P=1.000) and a higher rate of major bleeding events (P=0.008) in the LMWH group than the Control group, and their magnitude and significance were maintained in the propensity matched analysis. In the matched cohorts, there was no significant difference in the total volume of red blood cell transfusion (P=0.552), assisted mechanical ventilation time (P=0.542), and the ICU stay time (P=0.166) between the two groups; while the volume of drainage (P<0.001) and the duration of drainage (P<0.001) in the LMWH group were significantly more than the Control group, and the incidence of poor wound healing (P=0.009) and the postoperative hospitalization time (P<0.001) were significantly increased in the LMWH group. Conclusions:Early prophylactic anticoagulation with LMWH could not reduce the incidence of embolism events after MICS. Instead, it might increase postoperative major bleeding events and prolong drainage tube indwelling time and the length of hospital stay.

Project description:BackgroundOpioid dependence is a public health crisis and surgery is a risk factor for long-term opioid use. Though minimally invasive surgery (MIS) is associated with less perioperative pain, demonstrating an association with less long-term opioid use would be another reason to justify adoption of minimally invasive techniques. We compared the rates for long-term opioid prescriptions among patients in a large national database who underwent minimally invasive and open colectomy.MethodsUsing the MarketScan Database, we retrospectively analyzed patients undergoing colon resection for benign and malignant diseases between 2013 and 2017. Among opioid-naïve patients who had ≥ 1 opioid prescriptions filled perioperatively (30 days before surgery to 14 days after discharge), propensity score matching was applied for group comparisons [open (OS) versus MIS, and laparoscopic (LS) versus robotic-assisted surgery (RS)]. The primary outcome was long-term opioid use defined as the proportion of patients with ≥ 1 long-term opioid prescriptions filled 90-180 days after discharge. Risks factors for long-term opioid use were assessed using logistic regression.ResultsAmong the 5413 matched pairs in the MIS versus OS cohorts, MIS significantly reduced long-term opioid use of 'any opioids' (13.3% vs. 20.9%), schedule II/III opioids (11.7% vs. 19.2%), and high-dose opioids (4.3% vs. 7.7%; all p < 0.001). Among the 1195 matched pairs in the RS versus LS cohorts, RS was associated with less high-dose opioids (2.1% vs. 3.8%, p = 0.015) 90-180 days after discharge. Other risk factors for long-term opioid use included younger age, benign indications, tobacco use, mental health conditions, and > 6 Charlson comorbidities.ConclusionMinimally invasive colectomy is associated with a significant reduction in long-term opioid use when compared to OS. Robotic-assisted colectomy was associated with less high-dose opioids compared to LS. Increasing adoption of minimally invasive surgery for colectomy and including RS, where appropriate, may decrease long-term opioid use.

Project description:BackgroundTo investigate the differences in survival between lobectomy and sub-lobar resection for elderly stage I non-small-cell lung cancer (NSCLC) patients using the Surveillance, Epidemiology, and End Results (SEER) registry.MethodThe data of stage IA elderly NSCLC patients (≥ 70 years) with tumors less than or equal to 3 cm in diameter were extracted. Propensity-matched analysis was used. Lung cancer-specific survival (LCSS) was compared among the patients after lobectomy and sub-lobar resection. The proportional hazards model was applied to identify multiple prognostic factors.ResultsA total of 3,504 patients met criteria after propensity score matching (PSM). Although the LCSS was better for lobectomy than for sub-lobar resection in patients with tumors ≤ 3 cm before PSM (p < 0.001), no significant difference in the LCSS was identified between the two treatment groups after PSM (p = 0.191). Multivariate Cox regression showed the elder age, male gender, squamous cell carcinoma (SQC) histology type, poor/undifferentiated grade and a large tumor size were associated with poor LCSS. The subgroup analysis of tumor sizes, histologic types and lymph nodes (LNs) dissection, there were also no significant difference for LCSS between lobectomy and sub-lobar resection. The sub-lobar resection was further divided into segmentectomy or wedge resection, and it demonstrated that no significant differences in LCSS were identified among the treatment subgroups either. Multivariate Cox regression analysis showed that the elder age, poor/undifferentiated grade and a large tumor size were a statistically significant independent factor associated with survival.ConclusionIn terms of LCSS, lobectomy has no significant advantage over sub-lobar resection in elderly patients with stage IA NSCLC if lymph node assessment is performed adequately. The present data may contribute to develop a more suitable surgical treatment strategy for the stage IA elderly NSCLC patients.
