17159 Background: Sleeve Lobectomy (Sl) is generally considered a surgical alternative of choice to Pneumonectomy (Pn) for the treatment of central NSCLC. The aim of this study is to value if the Sl could be really a Lung saving procedure that warrants right survivals, according to stage of disease, with acceptable perioperative risks. Methods: In 165 patients (67 Sl and 98 Pn) operated from 1995 to 2003 for NSCLC of main bronchus we have analyzed the hospital stay, morbidity and mortality within 30 days, long term survival. In 39 Sl and 46 Pn we compared spyrometric volume’s changes at a distance of 6–24 months from operation. Sl was performed where it was technically possible. Long term survivals had been separated and comparated according to pathologic stadium (TNM 1997) and lymphonodal involvement: all these data were estimated by Kaplan-Meier method and log rank test. All statistical data underwent SPSS elaboration and significant assumption for p < 0.05. Results: In our population of study we didn’t check any statistically significant’s differences comparing age, sex or preoperative Fev1. Complications occurred in 28% of cases where Sl was performed and in 36.7% after Pn with a mortality rate of 2.9% vs 5.1%. Average hospital staying was longer in patients underwent to Pneumonectomy. Long term survival (5 years) in Sl group is 36% and 24% in Pn group with a statistically significant difference P = 0.016, but this difference is not evident from the comparison between the two group’s survivals based on pathological stadium or lymphonodal involvement. Spyrometric values showed a global Fev1 reduction of 245 ml (−10%) after Sl procedure and 884ml (36.3%) after Pn with a significant difference of p = 0.0042. Conclusions: In this study Sl got similar survival results if not better, with those obtained after Pn. Moreover, Sl showed to be a lung sparing procedure with an acceptable operative risk. These data confirmed that SL is the gold standard surgical procedure in the treatment of central tumors where if technically possible.

Reports on the long-term survival effect of edaravone, which was approved for the treatment of amyotrophic lateral sclerosis (ALS) in 2015 in Japan, are rare. Herein, we report our retrospective analysis of 45 consecutive patients with ALS who initially visited our hospital between 2013 and 2018. Of these, 22 patients were treated with edaravone for an average duration of 26.6 (range, 2–64) months, whereas the remaining patients were not treated with edaravone and comprised the control group. There were no differences in baseline demographics between the two groups. The primary endpoint was tracheostomy positive-pressure ventilation (TPPV) or death, and the follow-up period ended in December 2020. The survival rate was significantly better in the edaravone group than in the control group based on the Kaplan–Meier analysis, which revealed that the median survival durations were 49 (9–88) and 25 (8–41) months in the edaravone and control groups, respectively (p = 0.001, log-rank test). There were no serious edaravone-associated adverse effects during the study period. Overall, the findings of this single-center retrospective study suggest that edaravone might prolong survival in patients with ALS.

Retrospective studies indicate that cancer survival may be affected by the anaesthetic technique. Propofol seems to be a better choice than volatile anaesthetics, such as sevoflurane. The first two retrospective studies suggested better long-term survival with propofol, but not for breast cancer. Subsequent retrospective studies from Asia indicated the same. When data from seven Swedish hospitals were analysed, including 6305 breast cancer patients, different analyses gave different results, from a non-significant difference in survival to a remarkably large difference in favour of propofol, an illustration of the innate weakness in the retrospective design. The largest randomised clinical trial, registered on clinicaltrial.gov, with survival as an outcome is the Cancer and Anesthesia study. Patients are here randomised to propofol or sevoflurane. The inclusion of patients with breast cancer was completed in autumn 2017. Delayed by the pandemic, one-year survival data for the cohort were presented in November 2020. Due to the extremely good short-term survival for breast cancer, one-year survival is of less interest for this disease. As the inclusions took almost five years, there was also a trend to observe. Unsurprisingly, no difference was found in one-year survival between the two groups, and the trend indicated no difference either.

Abstract Aim To investigate whether preoperative malnutrition is associated with long term outcome and survival in patients undergoing radical oesophagectomy for oesophageal or oesophagogastric junction cancer. Background & Methods Dysphagia, weight loss, chemo-radiationtherapy frequently lead to malnutrition in patients with oesophageal or oesophagogastric junction cancer. Severe malnutrition is associated with higher risk of postoperative complications but little is known on the correlation with long term survival. We conducted a single center retrospective study on a prospectively collected database of patients undergoing oesophagectomy from 2008 and 2012 in order to evaluate the impact of preoperative malnutrition with postoperative outcome and long term survival. Preoperative malnutrition was classified as: prealbumin level less than 220 mg/dL (PL), MUST index (Malnutrition Universal Screeening Tool) >2 and weight loss >10%. Results 177 consecutive patients were considered: due to incomplete data 60 were excluded from the analysis that was performed on 117 patients. PL was reported in 52 (44%) patients, MUST index was recorded in 62 (53%), 58 (49%) patients presented more than 10% weight loss at the preoperative evaluation. PL was associated with more postoperative Clavien-Dindo 1-2 complications (p=0.048, OR 2.35 95%IC 1.001-5.50), no differences were observed in mortality, anastomotic leak, major pulmonary complications. MUST index was not correlated with postoperative complications nor mortality but resulted worse in patients treated with chemo-radiotherapy (p=0.046, OR 1.92 95%CI 1.011-3.64). Weight loss >10% was not associated with postoperative complications or mortality. Overall 7 years survival rate was 69%. and DFS was 68%. Malnourished patients did not differ from non-malnourished regarding age, sex, tumor site, tumor stage and histology. No significant difference in 7 years survival rates was observed in patients with PL <220 mg/dL ( 55 % vs 67%), neither in patients with MUST score>2 (58% vs 72%), nor in patients with weight loss >10% (53% vs 70%). Conclusions Malnutrition is more common in patients treated with chemoradiation therapy and it is associated with postoperative complications. However, both long term and disease free survival are not affected by preoperative nutritional status. Larger patient population and data on long term postoperative nutritional status will be analyzed in further studies.

Abstract A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was ‘In [dialysis patients undergoing a valve replacement] is [a bioprosthetic valve superior to a mechanical prosthesis] for [long-term survival and morbidity]’. Altogether more than 501 papers were found using the reported search, of which five represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. There was limited high-quality evidence with all studies being retrospective. One meta-analysis and four cohort studies provided the evidence that there was no significant difference in long-term survival based on prosthesis type. However, the majority of studies demonstrated a significantly higher rate of valve-related complications including bleeding and thromboembolism, and readmission to hospital in the mechanical valve prosthesis group, likely related to the requirement for long-term anticoagulation. We conclude that overall long-term survival in dialysis-dependent patients is poor. While prosthesis type does not play a significant contributing role to long-term survival, bioprosthetic valves were associated with significantly fewer valve-related complications. Based on the available evidence, a bioprosthetic valve may be more suitable in this high-risk group of patients as it may avoid the complications associated with long-term anticoagulation without any reduction in long-term survival.

Abstract Background The treatment effect in survival analysis is commonly quantified as the hazard ratio, and tested statistically using the standard log-rank test. Modern anticancer immunotherapies are successful in a proportion of patients who remain alive even after a long-term follow-up. This new phenomenon induces a nonproportionality of the underlying hazards of death. Methods The properties of the net survival benefit were illustrated using the dataset from a trial evaluating ipilimumab in metastatic melanoma. The net survival benefit was then investigated through simulated datasets under typical scenarios of proportional hazards, delayed treatment effect, and cure rate. The net survival benefit test was computed according to the value of the minimal survival difference considered clinically relevant. As comparators, the standard and the weighted log-rank tests were also performed. Results In the illustrative dataset, the net survival benefit favored ipilimumab [Δ(0) = 15.8%, 95% confidence interval = 4.6% to 27.3%, P = .006]. This favorable effect was maintained when the analysis was focused on long-term survival differences (eg, >12 months, Δ(12) = 12.5% (95% confidence interval = 4.4% to 20.6%, P = .002). Under the scenarios of a delayed treatment effect and cure rate, the power of the net survival benefit test compared favorably to the standard log-rank test power and was comparable to the power of the weighted log-rank test for large values of the threshold of clinical relevance. Conclusion The net long-term survival benefit is a measure of treatment effect that is meaningful whether or not hazards are proportional. The associated statistical test is more powerful than the standard log-rank test when a delayed treatment effect is anticipated.

Abstract BACKGROUND Between 1995 and 2002 the EORTC Brain Tumor Group conducted a prospective phase III study on adjuvant procarbazine, CCNU and vincristine (PCV) chemotherapy in anaplastic oligodendroglioma (AOD). A mature follow-up presented in 2012 showed survival benefit of the addition of PCV, in particular in 1p/19q co-deleted tumors and tumors with MGMT promoter methylation. We now present very long term follow-up. MATERIALS AND METHODS Patients were eligible if locally diagnosed with a newly diagnosed AOD. They were randomized between radiotherapy (RT, 33 x 1.8 Gy) and the same RT followed by 6 cycles PCV (RT/PCV). Primary endpoints were overall survival (OS) and progression free survival (PFS). 1p/19q status (FISH) was determined in 300 patient. Kaplan- Meier technique and Cox modeling were used for long term survival analysis. Primary analyses were adjusted for known prognostic factors. For other analyses no adjustment was performed. RESULTS With 368 patients included, a median follow-up of 18.4 years and 307 (83%) survival events, median and 20-year survival after RT/PCV versus RT alone were 42.3 mo and 16.8% vs 30.6 months and 10.1% (HR 0.78; 95% CI (0.63, 0.98), adjusted p=0.06). Eighty patients were 1p/19q codel of which 26 (33%) were still alive, in this subgroup median and 20-year survival after RT/PCV versus RT alone were 14 years and 37.1% versus 9.3 years and 13.6% (HR 0.60, 95% CI (0.35, 1.03), unadjusted p=0.06). Twenty year PFS in 1p/19q codel was 31.3% in RT/PCV treated patients and 10.8% in RT only treated patients (HR 0.49, 95% CI (0.29, 0.83), unadjusted p=0.007). In the 1p/19q codel subgroup age, WHO PS and necrosis at pathology were identified to be of independent prognostic value for OS. CONCLUSION This long term analysis confirms the earlier conclusions and provides data on long term survival in this patient group. In 1p/19q codel patients treated with RT/PCV, the 20-year PFS and OS rates are 31% and 37% respectively.

Abstract Abstract 3551 Background: Allogeneic hematopoietic cell transplantation (HCT) may even cure leukemia following relapse or primary induction failure. Several pre-transplant variables including age, duration of remission, poor-risk cytogenetics, tumor burden at HCT, type of donor, and performance status reportedly affected the post-HCT prognosis of leukemia that is not in remission. However, there has been insufficient examination of the factors required to achieve long-term survival or cure of leukemia that is not in remission at HCT. We might consider long-term survival without relapse, particularly for more than 5 years, as ‘likely cure' of leukemia. Therefore, we evaluated the factors that contribute to long-term survival (for more than 5 years) in patients with active leukemia at HCT. Method: We retrospectively performed an analysis of leukemia not in remission at HCT performed at our single institute between January 1999 and July 2009. Forty-two patients aged from 15 to 67 years (median age: 39 years) received intensified myeloablative (n=9), myeloablative (n=11) or reduced-intensity conditioning (n=22) for HCT. Twelve patients received individual chemotherapy for cytoreduction within the three weeks before reduced-intensity conditioning for HCT. Diagnoses included de novo AML (n=17), ALL (n=12), CML-AP (n=2), MDS/AML (n=10) and plasma cell leukemia (n=1). In those with acute leukemia, cytogenetic abnormalities were intermediate (n=17, 44%)or poor (n=22, 56%). Seven patients were primarily refractory to induction chemotherapy. The other patients relapsed after conventional chemotherapy or the first HCT. The median number of blast cells in bone marrow (BM) was 26.0% (range; 0.2–100) before the start of chemotherapy for HCT. Six patients had leukemic involvement of the central nerve system. Stem cell sources were related BM (n=3, 7%), related peripheral blood (n=13, 31%) unrelated BM (n=20, 48%) and unrelated cord blood (CB) (n=6, 14%). Thirty-one pairs were matched for HLA-A, B and DRB1 antigens. Three patients were mismatched for one HLA antigen (two at HLA-A, one at HLA-B), and seven were mismatched for two (two at HLA-A and B, five (all CB) at HLA-B and DRB1). The remaining patient was mismatched for all three antigens. Prophylaxis for acute GVHD consisted of calcineurin alone (n=5), calcineurin combined with short-term methotrexate (n=32), calcineurin combined with mycophenolate mofetil (n=2) or none (n=3). In this study, we defined long-term survival as survival without relapse for more than 5 years. Results: Engraftment was achieved in 33 (79%) of 42 patients. Median time to engraftment was 17 days (range: 9–32). Five patients died early after HCT (range 4–20 days). Twenty four (65%) of 37 evaluable patients developed acute GVHD (eight grade I, nine grade II, five grade III, two grade IV), and 12 (50%) of 24 evaluable patients developed chronic GVHD (1 limited, 11 extensive). With a median follow up of 85 months for surviving patients, the five-year Kaplan-Meier estimates of leukemia-free survival rate and overall survival (OS) were 17% and 19%, respectively. At five years, the cumulative probability of non-relapse mortality was 38%. In the univariate analyses of impact of pre-transplant variables on OS, poor-risk cytogenetics, number of BM blasts (>26%), MDS/AML and CB as stem cell source were significantly associated with worse prognosis (p=.03, p=.01, p=.02 and p<.001, respectively). In addition, the five-year Kaplan-Meier estimates of OS in patients with and without cGVHD were 66.7% and 0% (p<.001) respectively. Conclusion: Graft-versus-leukemia effects mediated by cGVHD may have played a crucial role in long-term survival in, or cure of active leukemia. We speculate that effective cytoreduction by individual chemotherapy and/or conditioning for HCT to control disease until cGVHD subsequently occurred might be also important, particularly in leukemia with rapid proliferation. However, intensive conditioning for HCT did not appear to be indispensable in relatively indolent leukemia, even with non-remission status at HCT. In addition, based on our results, CB might be unsuitable as a source of stem cells for leukemia that is active at the time of HCT. Disclosures: No relevant conflicts of interest to declare.

Abstract OBJECTIVES The aim of this study was to evaluate the impact of institutional volume on long-term outcomes following lung transplantation (LTx) in the USA. METHODS Adults undergoing LTx were identified in the United Network for Organ Sharing registry. Patients were divided into equal size tertiles according to the institutional volume. All-cause mortality following LTx was evaluated using the risk-adjusted multivariable Cox regression and the Kaplan–Meier analyses, and compared between these volume cohorts at 3 points: 90 days, 1 year (excluding 90-day deaths) and 10 years (excluding 1-year deaths). Lowess smoothing plots and receiver-operating characteristic analyses were performed to identify optimal volume thresholds associated with long-term survival. RESULTS A total of 13 370 adult LTx recipients were identified. The mean annual centre volume was 33.6 ± 20.1. After risk adjustment, low-volume centres were found to be at increased risk for 90-day mortality, [hazard ratio (HR) 1.56, P < 0.001], 1-year mortality excluding 90-day deaths (HR 1.46, P < 0.001) and 10-year mortality excluding 1-year deaths (HR 1.22, P < 0.001). These findings persisted when the centre volume was modelled as a continuous variable. The Kaplan–Meier analysis also demonstrated significant reductions in survival at each of these time points for low-volume centres (each P < 0.001). The 10-year survival conditional on 1-year survival was 37.4% in high-volume centres vs 28.0% in low-volume centres (P < 0.001). The optimal annual volume threshold for long-term survival was 26 LTx/year. CONCLUSIONS The institutional volume impacts long-term survival following LTx, even after excluding deaths within the first post-transplant year. Identifying the processes of care that lead to longer survival in high-volume centres is prudent.

SUMMARY Diabetes mellitus (DM) is one of the most common comorbidities in esophageal cancer patients who undergo esophagectomy. It is well established that DM has an unfavorable impact on short-term outcomes of patients with surgically treated esophageal cancer; however, whether DM has any impact on long-term survival of these patients remains unclear. We performed the first meta-analysis to investigate the impact of DM on survival of surgically treated esophageal cancer patients. We searched the following databases systematically to retrieve relevant studies on January 2, 2019: PubMed, Embase, and Web of Science. The main outcome data consisting of 3- and 5-year overall survival (OS) rates and hazard ratios (HRs) of OS were extracted to compare survival between patients with and without DM. We finally included for meta-analysis a total of eight cohort studies involving 5,044 esophageal cancer patients who underwent esophagectomy. We found no significant difference between 3-year (risk ratio [RR] = 0.94, 95% CI: 0.73–1.21; P = 0.65) and 5-year (RR = 0.92, 95% CI: 0.80–1.08; P = 0.31) OS rates between patients with and without DM after esophagectomy. Moreover, DM was not found to be an independent predictor of OS for these patients (HR = 1.10, 95% CI: 0.65–1.84; P = 0.72). Our study suggests that DM appears to have no significant impact on long-term survival of esophageal cancer patients who undergo esophagectomy. To improve the prognosis of these patients, it may be more important to control glycemic level in patients with DM who undergo esophagectomy. However, further high-quality studies with appropriate adjustment for confounding factors are needed to verify this conclusion.
