Normothermic regional perfusion (NRP) in controlled donation after the circulatory determination of death (cDCD) is a growing preservation technique for abdominal organs that coexists with the rapid ...recovery of lungs. We aimed to describe the outcomes of lung transplantation (LuTx) and liver transplantation (LiTx) when both grafts are simultaneously recovered from cDCD donors using NRP and compare them with grafts recovered from donation after brain death (DBD) donors. All LuTx and LiTx meeting these criteria during January 2015 to December 2020 in Spain were included in the study. Simultaneous recovery of lungs and livers was undertaken in 227 (17%) donors after cDCD with NRP and 1879 (21%) DBD donors (P < .001). Primary graft dysfunction grade-3 within the first 72 hours was similar in both LuTx groups (14.7% cDCD vs. 10.5% DBD; P = .139). LuTx survival at 1 and 3 years was 79.9% and 66.4% in cDCD vs. 81.9% and 69.7% in DBD (P = .403). The incidence of primary nonfunction and ischemic cholangiopathy was similar in both LiTx groups. Graft survival at 1 and 3 years was 89.7% and 80.8% in cDCD vs. 88.2% and 82.1% in DBD LiTx (P = .669). In conclusion, the simultaneous rapid recovery of lungs and preservation of abdominal organs with NRP in cDCD donors is feasible and offers similar outcomes in both LuTx and LiTx recipients to transplants using DBD grafts.

The aim of this study was to compare the outcomes of lung transplantations using grafts from donors aged over 70 years against those performed using younger donors.
This retrospective single-centre ...analysis includes lung transplants conducted at our institution from January 2014 to June 2022. Lung recipients were classified into 2 groups based on donor age (group A <70 years; group B ≥70 years). Variables regarding demographics, peri and postoperative outcomes and survival were included. The statistical analysis approach included univariable analysis, propensity score matching to address imbalances in donor variables (smoking status), recipient characteristics (sex, age, diagnosis and lung allocation score) and calendar period and survival analysis.
A total of 353 lung transplants were performed in this period, 47 (13.3%) using grafts from donors aged over 70 years. Donors in group B were more frequently women (70.2% vs 51.6%, P = 0.017), with less smoking history (22% vs 43%, P = 0.002) and longer mechanical ventilation time (3 vs 2 days, P = 0.025). Recipients in group B had a higher lung allocation score (37.5 vs 35, P = 0.035). Postoperative variables were comparable between both groups, except for pulmonary function tests. Group B demonstrated lower forced expiratory volume 1 s levels (2070 vs 2580 ml, P = 0.001). The propensity score matching showed a lower chance of chronic lung allograft dysfunction by 12% for group B. One-, three- and five-year survival was equal between the groups.
The use of selected expanded-criteria donors aged over 70 years did not result in increased postoperative morbidity, early mortality or survival in this study.
Abstract
OBJECTIVES
Controlled donation after circulatory death (cDCD) donors are becoming a common source of organs for transplantation globally. However, the graft survival rate of cDCD abdominal ...organs is inferior to that of organs from brain-dead donors. The rapid retrieval (RR) technique is used by most donor organ procurement teams. The abdominal normothermic regional perfusion (A-NRP) technique has been implemented to minimize warm ischaemic damage to the abdominal organs. However, there is limited information on the effect of A-NRP on the quality of the donor lungs. This study aimed to compare lung transplantation outcomes using lungs procured from cDCD donors using the A-NRP and abdominal RR techniques.
METHODS
A single-centre retrospective analysis of consecutive transplant recipients of cDCD lungs from June 2013 to December 2019 was performed. The recipients were divided into 2 cohorts according to the abdominal procurement technique used. The recipient and donor characteristics (age, sex, cause of brain injury, warm ischaemic time, diagnosis, lung allocation score and other factors), incidence of primary graft dysfunction and early survival were monitored.
RESULTS
Twenty-eight consecutive lung transplantation recipients were identified (median age 59 years; 61% male); 14 recipients received lungs using the A-NRP and 14 using abdominal RR for abdominal organ retrieval. There were no significant differences in the baseline characteristics, primary graft dysfunction (P = 0.70), hospital mortality (P = 1.0) and 1-year survival rate (P = 1.0) between the 2 groups.
CONCLUSIONS
No difference was observed in lung transplantation outcomes irrespective of the abdominal organ procurement technique used (A-NRP or abdominal RR).
Lung transplantation (LTx) is an established therapy for end-stage lung disease in selected patients; however, it is limited by the shortage of donor organs 1.

To determine the incidence of occult N1/N2 nodal metastases and associated risk factors in patients with non-small cell lung cancer no larger than 3cm and deemed cN0 by CT and PET-CT ...in a prospective, multicentre national database.
Patients with a NSCLC no larger than 3cm, deemed cN0 by PET-CT and CT scan, who had undergone at least a lobectomy, were selected from a national multicentre database of 3533 patients who had undergone anatomic lung resection between 2016 and 2018.
Clinical and pathological variables of patients with pN0 and patients with pN1/N2 were compared to identify factors associated with the presence of lymph node metastases. Chi2 and the Mann–Whitney U test were used for categorical and numerical variables, respectively. All variables with p<0.2 in the univariate analysis were included in the multivariate logistic regression analysis.
The study included 1205 patients from the cohort. The incidence of occult pN1/N2 disease was 10.70% (95%CI, 9.01–12.58).
The multivariable analysis revealed that the degree of differentiation, size, location (central or peripheral) and SUV of the tumour in PET, surgeon experience and number of lymph nodes resected were associated with occult N1/N2 metastases.
The incidence of occult N1/N2 in patients with bronchogenic carcinoma with cN0 tumours no larger than 3cm is no negligible. Data about the degree of differentiation, tumour size in CT scan, maximal uptake of the tumour in PET-CT, location (central or peripheral), number of lymph nodes resected and surgeon seniority is relevant in order to detect patients at risk.
Abstract
OBJECTIVES
Most transplant centres use donation after brain death (DBD) criteria to assess the quality of controlled donation after circulatory death (cDCD) lungs. However, research on the ...relationship between DBD extended criteria and cDCD lung transplantation outcomes is limited. We investigated the outcomes of using DBD extended criteria donor organs in cDCD lung transplantation, compared to the standard criteria cDCD lung transplantation.
METHODS
A retrospective chart review of consecutive cDCD lung referrals to Hospital Universitario Puerta de Hierro-Majadahonda from June 2013 to December 2019 was undertaken. Donors were divided into standard and extended criteria groups. Early outcomes after lung transplant were compared between these groups using the Kaplan–Meier method and log-rank test.
RESULTS
Thirty out of 91 cDCD donor lung offers were accepted for transplantation, of which 11 were from standard criteria donors and 19 were extended criteria donors. The baseline characteristics of the 2 recipient groups were similar. There were no differences in the rates of grade 3 primary graft dysfunction at 72 h after lung transplantation (21% vs 18%), duration of mechanical ventilation (48 h vs 36 h), total intensive care unit stay (10 days vs 7 days) and 1-year survival (89% vs 90%).
CONCLUSIONS
Carefully selecting cDCD lungs from outside the standard acceptability criteria may expand the existing donor pool with no detrimental effects on lung transplantation outcomes.

Cold static donor lung preservation at 10°C appears to be a promising method to safely extend the cold ischemic time (CIT) and improve lung transplant (LTx) logistics.
LTx from ...November 2021 to February 2023 were included in this single institution, prospective, non-randomized study comparing prolonged preservation at 10°C versus standard preservation on ice. The inclusion criteria for 10°C preservation were suitable grafts for LTx without any donor retrieval concerns. Primary endpoint: primary graft dysfunction (PGD) grade-3 at 72-h. Secondary endpoints: clinical outcomes, cytokine profile and logistical impact.
Thirty-three out of fifty-seven cases were preserved at 10°C. Donor and recipient characteristics were similar across the groups. Total preservation times (h:min) were longer (p<0.001) in the 10°C group 1st lung: median 12:09 (IQR 9:23–13:29); 2nd: 14:24 (12:00–16:20) vs. standard group 1st lung: median 5:47 (IQR 5:18–6:40); 2nd: 7:15 (6:33–7:40). PGD grade-3 at 72-h was 9.4% in 10°C group vs. 12.5% in standard group (p=0.440). Length of mechanical ventilation (MV), ICU and hospital stays were similar in both groups. Thirty and ninety-day mortality rates were 0% in 10°C group (vs. 4.2% in standard group). IL-8 concentration was significantly higher 6-h post-LTx in the standard group (p=0.025) and IL-10 concentration was increased 72-h post-LTx in the 10°C group (p=0.045).
Preservation at 10°C may represent a safe and feasible strategy to intentionally prolong the CIT. In our center, extending the CIT at 10°C may allow for semi-elective LTx and improve logistics with similar outcomes compared to the current standard preservation on ice.
Summary
Controlled donation after circulatory death donors (cDCD) are becoming a frequent source of lungs grafts worldwide. Conversely, lung transplantations (LTx) from uncontrolled donors (uDCD) are ...sporadically reported. We aimed to review our institutional experience using both uDCD and cDCD and compare to LTx from brain death donors (DBD). This is a retrospective analysis of all LTx performed between January 2013 and December 2019 in our institution. Donor and recipient characteristics were collected and univariate, multivariate and survival analyses were carried out comparing the three cohorts of donors. A total of 239 (84.7%) LTx were performed from DBD, 29 (10.3%) from cDCD and 14 (5%) from uDCD. There were no statistically significant differences in primary graft dysfunction grade 3 at 72 h, 30‐ and 90‐day mortality, need for extracorporeal membrane oxygenation after procedure, ICU and hospital length of stay, airway complications, CLAD incidence or survival at 1 and 3 years after transplant (DBD: 87.1% and 78.1%; cDCD: 89.7% and 89.7%; uDCD: 85.7% and 85.7% respectively; P = 0.42). Short‐ and mid‐term outcomes are comparable between the three types of donors. These findings may encourage and reinforce all types of donation after circulatory death programmes as a valid and growing source of suitable organs for transplantation.
Lung transplantation from uncontrolled and controlled donors after circulatory death offers similar outcomes to brain death donors in terms of early and mid‐term results. Overall survival and CLAD‐free survival at 1 and 3 years are comparable between the three types of donors.
Abstract
OBJECTIVES
The relationship between operating time and postoperative morbidity has not been fully characterized in lung resection surgery. We aimed to determine the variables associated with ...prolonged operative times and their influence on postoperative complications after video-thoracoscopic lobectomy.
METHODS
Patients undergoing thoracoscopic lobectomy for lung cancer from December 2016 to March 2018, within the prospective registry of the Spanish Video-Assisted Thoracic Surgery Group were identified. Operating time was stratified by quartiles and complication rates analysed using chi-squared test. Primary outcomes included 30-day overall, pulmonary and cardiovascular complications and wound infection. Multivariable logistic regression analyses were performed to identify variables independently associated with operating time and their influence on the occurrence of postoperative complications.
RESULTS
Data of 1518 cases were examined. The median operating time was 174 min (interquartile range: 130–210 min). Overall morbidity rates significantly increased with surgical duration (20.5% vs 34.4% in the 1st and 4th quartiles, respectively, P < 0.05) and so did pulmonary complications (14.6% vs 26.4% in the 1st and 4th quartiles, respectively, P < 0.05). Differences were not found regarding cardiovascular and wound complications. After multivariable logistic regression analysis, operating time remained as an independent risk factor for overall (odds ratios, 2.05) and pulmonary complications (odds ratios, 2.01). Male sex, predicted postoperative diffusing capacity of the lung for carbon monoxide, number of lymphatic stations harvested, pleural adhesions, fissures completeness, lobectomy site, surgeon seniority, individual video-thoracoscopic surgeon experience and fissureless technique were identified as predictive factors for long operative time.
CONCLUSIONS
Prolonged operating time is associated with increased odds of postoperative complications. Modifiable factors contributing to prolonged operating time may serve as a target for quality improvement.
To study the impact of neoadjuvant therapies on postoperative complications and mortality among non-small-cell lung cancer (NSCLC) patients subjected to anatomic lung resection and included in the ...Spanish cohort of the video-assisted thoracic surgery (GE-VATS) multicenter database.
The study included a total of 3085 patients from 33 centers between December 2016 and March 2018. We performed a comparative analysis of the complications and mortality in patients who received neoadjuvant therapies (n = 263) versus those who did not (n = 2822). A propensity score-matched analysis was used to adjust for potential confounders. Association between exposure in two groups and outcomes were estimated by logistic regression weighted by inverse of probability of receiving the treatment that actually received.
In the unadjusted analysis, the chemotherapy (CT) and chemoradiotherapy (CRT) group presented a higher frequency of ICU readmissions, reinterventions, empyema, cardiovascular complications, a greater frequency of atrial fibrillation, and an increased need for blood product transfusions. In the adjusted group, CT and CRT patients had a higher rate of cardiovascular complications (CT p = 0.002; OR 2.29; 95% CI 1.34–3.94 and CRT p = 0.001; OR 2.90; 95% CI 1.52-5-52), arrhythmias (CT p = 0.013; OR 2.23; 95% CI 1.18–4.20 and CRT p = 0.046; OR 2.22; 95% CI 1.01–4.90) and transfussions (CT p = 0.042; OR 2.95; 95% CI 1.04–8.35 and CRT p < 0.001; OR 7.74; 95% CI 3.01-19-92).
Based on our series, neoadjuvant CT and CRT were associated with a higher rate of cardiovascular complications, arrhythmias and transfussions in patients with NSCLC subjected to anatomic lung resection.
