RESUMO

PURPOSE: Advances in surgical procedures and immunosuppressive therapies have considerably improved the outcomes of patients who have undergone liver transplantation in the past few decades. In 2020, the Italian Liver Transplant Working Group published practice-oriented algorithms for immunosuppressive therapy (IT) in adult liver transplant (LT) recipients. Due to the rapidly evolving LT field, regular updates to the recommendations are required. This review presents a consensus- and evidence-based update of the 2020 recommendations. METHODS: The Italian Liver Transplant Working Group set out to address new IT issues, which were discussed based on supporting literature and the specialists' personal experiences. The panel deliberated on and graded each statement before consensus was reached. RESULTS: A series of consensus statements were formulated and finalized on: (i) oncologic indications for LT; (ii) management of chronic LT rejection; (iii) combined liver-kidney transplantation; (iv) immunosuppression for transplantation with an organ donated after circulatory death; (v) transplantation in the presence of frailty and sarcopenia; and (vi) ABO blood group incompatibility between donor and recipient. Algorithms were updated in the following LT groups: standard patients, critical patients, oncology patients, patients with specific etiology, and patients at high immunologic risk. A steroid-free approach was generally recommended, except for patients with autoimmune liver disease and those at high immunologic risk. CONCLUSION: The updated consensus- and evidence-based 2024 recommendations for immunosuppression regimens in adult patients with ABO-compatible LT address a range of clinical variables that should be considered to optimize the choice of the immunosuppression treatment in clinical practice in Italy.

RESUMO

AIM: The aim of the study was to identify predictors of early tumor recurrence in patients with hepatocellular carcinoma (HCC) after liver transplantation (LT). METHODS: Retrospective cohort study in 237 consecutive liver recipients with HCC between 2016 and 2021. Multivariate logistic analysis was performed to identify predictors of early HCC recurrences. The impact of hypothermic-oxygenated perfusion (HOPE) on outcome was analyzed after propensity score weighting. RESULTS: Early recurrences were observed in 15 cases. Microvascular invasion (OR 3.737, 95% CI 1.246-11.206, p = 0.019) and cold ischemia time (OR 1.155, 95% CI 1.001-1.333, p = 0.049) were independently associated with a lower risk of HCC recurrences. After balancing for relevant variables, patients in the HOPE group had lower rates of tumor recurrence (weighted OR 0.126, 95% CI 0.016-0.989, p = 0.049) and higher recurrence free survival (weighted HR 0.132, 95% CI 0.017-0.999, p = 0.050). CONCLUSION: Reducing cold ischemia time and graft perfusion with HOPE can lead to lower rates of early HCC recurrences and higher recurrence-free survival.

RESUMO

INTRODUCTION: Kidney biopsy is performed to assess if an extended criteria graft can be used for transplantation. It may be performed before or after cross-clamping during organ procurement. This study aims to evaluate whether the timing of biopsy may modify cold ischemia times (CIT) and/or graft outcomes. METHODS: Kidney transplants performed in our center from January 2007 to December 2017 were analyzed. Grafts with preimplantation kidney biopsy were included. Biopsies were performed during surgical back table (ex situ kidney biopsy [ESKB]) until 2012 and since then before the aortic cross-clamping (in situ kidney biopsy [ISKB]). To overcome biases owing to different distributions, a propensity score model was developed. The study population consists in 322 patients, 115 ESKB, and 207 ISKB. RESULTS: CIT was significantly lower for ISKB (730 min ISKB vs. 840 min ESKB, p value = 0.001). In both crude (OR 0.27; 95% confidence interval, 95% CI 0.12-0.60; p value = 0.002) and adjusted analyses (OR 0.37; 95% CI 0.14-0.94; p value = 0.039), ISKB was associated with a reduced odd of graft loss when compared to ESKB. DISCUSSION/CONCLUSION: Performing preimplantation kidney biopsy during the recovery, prior to the aortic cross-clamping, may be a strategy to reduce CIT and improve transplant outcomes.

RESUMO

We describe a patient with liver metastases from colorectal cancer treated with chemotherapy and hepatic resection, who developed unresectable multifocal liver recurrence and who received liver transplantation using a novel planned technique: heterotopic transplantation of segment 2-3 in the splenic fossa with splenectomy and delayed hepatectomy after regeneration of the transplanted graft. We transplanted a segmental liver graft after in-situ splitting without any impact on the waiting list, as it was previously rejected for pediatric and adult transplantation. The volume of the graft was insufficient to provide liver function to the recipient, so we performed this novel operation. The graft was anastomosed to the splenic vessels after splenectomy, and the native liver portal flow was modulated to enhance graft regeneration, leaving the native recipient liver intact. The volume of the graft doubled during the next 2 weeks and the native liver was removed. After 8 months, the patient lives with a functioning liver in the splenic fossa and without abdominal tumor recurrence. This is the first case reported of a segmental graft transplanted replacing the spleen and modulating the portal flow to favor graft growth, with delayed native hepatectomy.

RESUMO

Gastrointestinal stromal tumours that are wild type for KIT and PDGFRA are referred to as WT GISTs. Of these tumours, SDH-deficient (characterized by the loss of SDHB) and quadruple WT GIST (KIT/PDGFRA/SDH/RAS-P WT) subgroups were reported to display a marked overexpression of FGF4, identifying a putative common therapeutic target for the first time. In SDH-deficient GISTs, methylation of an FGF insulator region was found to be responsible for the induction of FGF4 expression. In quadruple WT, recurrent focal duplication of FGF3/FGF4 was reported; however, how it induced FGF4 expression was not investigated. To assess whether overexpression of FGF4 in quadruple WT could be driven by similar epigenetic mechanisms as in SDH-deficient GISTs, we performed global and locus-specific (on FGF4 and FGF insulator) methylation analyses. However, no epigenetic alterations were detected. Conversely, we demonstrated that in quadruple WT GISTs, FGF4 expression and the structure of the duplication were intimately connected, with the copy of FGF4 closer to the ANO1 super-enhancer being preferentially expressed. In conclusion, we demonstrated that in quadruple WT GISTs, FGF4 overexpression is not due to an epigenetic mechanism but rather to the specific genomic structure of the duplication. Even if FGF4 overexpression is driven by different molecular mechanisms, these findings support an increasing biologic relevance of the FGFR pathway in WT GISTs, both in SDH-deficient and quadruple WT GISTs, suggesting that it may be a common therapeutic target.

RESUMO

It is a well-recognized fact that implementing new guidelines in clinical practice may be difficult; therefore the Italian Society for Organ and Tissue Transplantation (SITO) set out to define practical immunosuppression tools for the management of liver transplantation patients. In 2017, an Italian Working Group of liver transplant experts and hepatologists issued a set of consensus statements along with evidence-based recommendations on the use of everolimus after liver transplantation. This article presents the evidence- and consensus-based algorithms developed within the Italian Working Group, which are aimed towards guiding clinicians in the selection of immunosuppressive regimens for the management of adult liver transplant recipients in real-life practice. The liver transplant recipient population, typically managed in clinical practice, was divided into the following categories: (1) standard patients; (2) critically ill patients; (3) patients with a specific etiology; (4) patients with hepatocellular carcinoma; (5) and patients with de novo malignancies. The algorithms are divided into two parts, according to the time from transplantation (0-3 months and > 3 months) and are discussed here along with relevant supporting literature, when available. Ultimately, it is hoped that the evidence- and consensus-based algorithms developed within the Italian Working Group, and presented here, contribute to simplify, personalize, and optimize immunosuppression of liver transplantation recipients in clinical practice.

RESUMO

Transplant programs have been severely disrupted by the COVID-19 pandemic. Italy was one of the first countries with the highest number of deaths in the world due to SARS-CoV-2. Here we propose a management model for the reorganization of liver transplant (LT) activities and policies in a local intensive care unit (ICU) assigned to liver transplantation affected by restrictions on mobility and availability of donors and recipients as well as health personnel and beds. We describe the solutions implemented to continue transplantation activities throughout a given pandemic: management of donors and recipients' LT program, ICU rearrangement, healthcare personnel training and monitoring to minimize mortality rates of patients on the waiting list. Transplantation activities from February 22, 2020, the data of first known COVID-19 case in Italy's Emilia Romagna region to June 30, 2020, were compared with the corresponding period in 2019. During the 2020 study period, 38 LTs were performed, whereas 41 were performed in 2019. Patients transplanted during the COVID-19 pandemic had higher MELD and MELD-Na scores, cold ischaemia times, and hospitalization rates (p < 0.05); accordingly, they spent fewer days on the waitlist and had a lower prevalence of hepatocellular carcinoma (p < 0.05). No differences were found in the provenance area, additional MELD scores, age of donors and recipients, BMI, re-transplant rates, and post-transplant mortality. No transplanted patients contracted COVID-19, although five healthcare workers did. Ultimately, our policy allowed us to continue the ICU's operations by prioritizing patients hospitalized with higher MELD without any case of transplant infection due to COVID-19.

RESUMO

BACKGROUND: Double kidney transplantation allows the use of marginal kidneys with a significant improvement in the recovery of renal function expected after transplantation, although with a greater anesthesiologic and surgical risk. One-sided positioning, more cautious in the event of functional exhaustion, can be complex due to vascular anomalies. MATERIALS AND METHODS: We report the case of 2 double unilateral kidney transplants with vascular reconstructions. The first is a double kidney transplant from a 83-year-old donor. Both kidneys (score 5) had 2 arteries and the arterial patch was not usable. A cryopreserved arterial graft was used for the packaging of an arterial axis with which a single T-L anastomosis was performed; the 2 veins were also joined with the packaging of a single anastomosis. The second case is a double kidney transplant from a cadaveric donor performed on a recipient suffering from severe diffuse atheromasia. The right kidney had 2 arteries and the left kidney had 3 arteries (both score 5). The aortic patches and veins of the 2 kidneys were joined together and a single arterial and venous anastomosis was performed. RESULTS: The course has been uneventful. In both cases there were no perioperative vascular complications. CONCLUSIONS: The use of marginal organs is an increasingly common reality. Bench vascular reconstructions can further increase donation resources, safely enhancing the transplantation of already marginal organs that would otherwise not be usable and allowing the contralateral vascular axis to be kept intact.

RESUMO

Background: Primary soft tissue sarcomas arising from the male urinary and genital tract are rare tumors, only accounting for 1% to 2% of all malignancies of the genitourinary tract. Clinical management of advanced disease is lacking in standardized recommendations due to the rarity of the disease. To date, complete and extensive surgery represents the only curative and standardized approach for localized disease, while the impact of retroperitoneal lymphadenectomy and adjuvant treatments on clinical outcomes are still unclear. Similarly, a standardized systemic treatment for advanced metastatic disease is still missing. Cases Presentation: Four out of 274 patients have been identified in our sarcoma population. The mean age was 54 years (range = 45-73). The histotypes showed liposarcoma in 2 cases and leiomyosarcoma in the remaining 2 cases. In all 4 cases, the disease was localized at presentation, patients underwent complete surgery, and no adjuvant treatments were done. Three cases presented a recurrence of disease at a mean follow-up of 86 months (range = 60-106 months), more than 7 years. Two cases were treated with a second surgery and chemotherapy and 1 case only with chemotherapy. Discussion and Conclusions: Sharing data about clinical management of paratesticular mesenchymal tumors is a key issue due to the rarity of this tumor's subtype. In this article, we report the clinical history of 4 patients affected by paratesticular mesenchymal tumor. In particular, main issues of interest are the decision of postoperative treatment and systemic treatment at time of disease recurrence.

RESUMO

The objective of the study is to evaluate 10 years of down-staging strategy for liver transplantation (LT) with a median follow-up of 5 years. Data on long-term results are poor and less information is available for hepatocellular carcinoma (HCC) non-responder patients or those ineligible for down-staging. The outcome of 308 HCC candidates and the long-term results of 231 LTs for HCC performed between 2003 and 2013 were analyzed. HCCs were divided according to tumor stage and response to therapy: 145 patients were T2 (metering Milan Criteria, MC), 43 were T3 successfully down-staged to T2 (Down-Achieved), 20 were T3 not fully down-staged to T2 (Down-not Achieved), and 23 patients were T3 not receiving down-staging treatments (No-Down). The average treatment effect (ATE) of LT for T3 tumors was estimated using the outcome of 535 T3 patients undergoing non-LT therapies, using inverse probability weighting regression adjustment. The 24-month drop-out rate during waiting time was significantly higher in the down-staging groups: 27.6% vs. 9.2%, p < 0.005. After LT, the tumor recurrence rate was significantly different: MC 7.6%, Down-Achieved 20.9%, Down-not Achieved 31.6%, and No-Down 30.4% (p < 0.001). The survival rates at 5 years were: 63% in Down-Achieved, 62% in Down-not Achieved, 63% in No-Down, and 77% in MC (p = n.s.). The only variable related to a better outcome was the effective down-staging to T2 at the histological evaluation of the explanted liver: recurrence rate = 7.8% vs. 26% (p < 0.001) and 5-year patient survival = 76% vs. 67% (p < 0.05). The ATE estimation showed that the mean survival of T3-LT candidates was significantly better than that of T3 patients ineligible for LT [83.3 vs 39.2 months (+44.6 months); p < 0.001]. Long term outcome of T3 down-staged candidates was poorer than that of MC candidates, particularly for cases not achieving down-staging. However, their survival outcome was significantly better than that achieved with non-transplant therapies.

RESUMO

Donation after circulatory death (DCD) is a potential source of reducing organ demand. In Italy, DCD requires a 20-min no-touch period that prolongs warm ischemia and increases delayed graft function (DGF) risk and graft loss. We report here our preliminary experience of sequential use of normothermic regional perfusion (NRP), as standard procedure, and hypothermic oxygenated perfusion (HOPE), as an experimental technique of organ preservation, in 10 kidney transplants (KT) from five DCD Maastricht III with extensive functional warm ischemia time (fWIT) up to 325 min. During NRP, renal function tests were evaluated to accept organs which were retrieved according to standard fashion with biopsy. While waiting for pathology and cross-match results, organs were preserved with HOPE through pressure- and temperature-controlled arterial pulsatile flow. All grafts with Karpinski score ≤4 were used for conventional single KT with mean cold ischemia time of 584 ± 167 min and mean fWIT of 151 ± 132 min. At the end of HOPE, lactate levels increased significantly in all cases with DGF (P = 0.0095), which were 3/10 (30%). No primary nonfunctions were recorded, and all patients had sCr < 1.5 mg/dl at 6-month post-KT. NRP and HOPE for DCD may overcome fWIT limits safely, and lactate during HOPE predicts DGF.

RESUMO

BACKGROUND: The role of liver resection for metastatic breast carcinoma is still debated. METHODS: Fifty-one resected patients were reviewed. All patients received adjuvant chemotherapy after resection of the primary tumor. Clinicopathological characteristics and immunohistochemistry expression of estrogen (ER), progesterone (PR), human epidermal growth factor (HER2), or Ki67 were evaluated. RESULTS: The median number of metastases was 2; single metastases were present in 24 (47%) patients. The median tumor diameter was 4 cm. Major hepatectomies were performed in 31 (61%) patients. Postoperative mortality was null. Postoperative morbidity was 13.7%. The 1-, 5-, and 10-year survival rates were 92, 36, and 16% respectively. Eleven (21.6%) patients survived longer than 5 years and 8.9% are alive without recurrence 10 years after surgery. At the univariate analysis, tumor diameter, lymph node status, PR receptor status, and triple positive receptors (ER+/PR+/Her2+) were significantly related to survival. At the multivariate analysis, tumor diameter, PR receptor, and triple negative status were significantly related to the long-term outcome. CONCLUSION: Liver resection seems to be a safe and effective treatment for metastases from breast cancer, and encouraging long-term survival can be obtained with acceptable risk in selected patients. Tumors less than 5 cm and positive hormone receptor status are the best prognostic factors.

RESUMO

BACKGROUND The recovery of discarded human kidneys has increased in recent years and impels to use of unconventional organ preservation strategies that improve graft function. We report the first case of human kidneys histologically discarded and transplanted after hypothermic oxygenated perfusion (HOPE). CASE REPORT Marginal kidneys from a 78-year-old woman with brain death were declined by Italian transplant centers due to biopsy score (right kidney: 6; left kidney: 7). We recovered and preserved both kidneys through HOPE and we revaluated their use for transplantation by means of perfusion parameters. The right kidney was perfused for 1 h 20 min and the left kidney for 2 h 30 min. During organ perfusion, the renal flow increased progressively. We observed an increase of 34% for the left kidney (median flow 52 ml/min) and 50% for the right kidney (median flow 24 ml/min). Both kidneys had low perfusate's lactate levels. We used perfusion parameters as important determinants of the organ discard. Based on our previous organ perfusion experience, the increase of renal flow and the low level of lactate following 1 h of HOPE lead us to declare both kidneys as appropriate for dual kidney transplantation (DKT). No complications were reported during the transplant and in the post-transplant hospital stay. The recipient had immediate graft function and serum creatinine value of 0.95 mg/dL at 3 months post-transplant. CONCLUSIONS HOPE provides added information in the organ selection process and may improve graft quality of marginal kidneys.

RESUMO

The management of recurrent hepatocellular carcinoma untreatable with surgical options is based on systemic therapy with sorafenib. Due to the high rates of adverse events connected to the therapy with sorafenib, metronomic capecitabine seems a promising strategy for these patients. We analyzed the data of 38 patients with hepatocellular carcinoma recurrent after liver transplantation performed at our center. We compared the outcome of 17 patients receiving metronomic capecitabine versus 20 patients experiencing best supportive care and versus the data of the literature about treatment with sorafenib. In the group treated with metronomic capecitabine we observed an increased survival after tumor recurrence at the univariate and multivariate analysis compared to the group of best supportive care (median 22 months vs. 7 months, p < 0.01). Data from the literature on the use of sorafenib showed outcomes like our study group, with similar patient and tumoral features. The episodes of acute rejection and the tumor stage at the recurrence showed a correlation with patient survival at the univariate analysis. The metronomic capecitabine for hepatocellular cancer recurrent after liver transplantation seems effective without important adverse events and comparable results to sorafenib.

RESUMO

OBJECTIVE: To evaluate the whole experience of liver transplantation (LT) with donors ≥70 years in a single center not applying specific donor/recipient matching criteria. BACKGROUND: LT with very old donors has historically been associated with poorer outcomes. With the increasing average donor age and the advent of Model for End-stage Liver Diseases (MELD) score-based allocation criteria, an optimal donor/recipient matching is often unsuitable. METHODS: Outcomes of all types of LTs were compared according to 4 study groups: patients transplanted between 1998 and 2003 with donors <70 (group 1, n = 396) or ≥70 years (group 2, n = 88); patients transplanted between 2004 and 2010 with donors <70 (group 3, n = 409), or ≥70 years (group 4, n = 190). From 2003, graft histology was routinely available before cross-clamping, and MELD-driven allocation was adopted. RESULTS: Groups 1 and 2 were similar for main donor and recipient variables, and surgical details. Group 4 had shorter donor ICU stay, lower rate of moderate-to-severe graft macrosteatosis (2.3% vs 8%), and higher recipient MELD score (22 vs 19) versus group 3. After 2003, median donor age, recipient age, and MELD score significantly increased, whereas moderate-to-severe macrosteatosis and ischemia time decreased. Five-year graft survival was 63.6% in group 1 versus 59.1% in group 2 (P = 0.252) and 70.9% in group 3 versus 67.6% in group 4 (P = 0.129). Transplants performed between 1998 and 2003, recipient HCV infection, balance of risk score >18, and pre-LT renal replacement treatments were independently associated with worse graft survival. CONCLUSIONS: Even without specific donor/recipient matching criteria, the outcomes of LT with donors ≥70 and <70 years are comparable with appropriate donor management.

Kidney injury is a common clinical feature among liver transplantation (LT) candidates that heavily affects prognosis and complicates the surgical decision-making process. Up to 20% of patients undergoing LT demonstrate some degree of renal impairment, and 2% will benefit from a combined liver-kidney transplantation (LKT). We present a case-control study of all patients who underwent LKT and combined liver-dual kidney transplantation (LDKT) from November 2013 to March 2016. For the selection of LDKT candidates, a histological-based algorithm was applied: when evaluating extended criteria donors (ECDs), with any Remuzzi score between 4 and 7, we would consider performing a LDKT instead of a simple LKT. Study groups were similar for recipient variables. In the LDKT group, donor age, donor risk index, and donor body mass index were found to be significantly higher. Biopsies obtained from all pairs of kidney grafts in the LDKT group demonstrated the following Remuzzi scores: 4+4, 4+4, 7+1, 4+5. Despite longer operative times for the LDKT procedure, no differences were observed regarding the main investigated outcome parameters. Overall survival was 100% (LDKT) and 91% (LKT, P > 0.99). This is a preliminary experience which might indicate that LDKT is a safe, feasible, and resource-effective technique. The evaluation of a larger cohort, as well as the experience from other centers, would be needed to clearly identify its role in the ECD era. Liver Transplantation 23:28-34 2017 AASLD.

RESUMO

BACKGROUND: Leiomyosarcoma of vascular origin is a rare tumor, occurring mainly in the inferior vena cava (IVC). When involving the hepatic vein confluence, it often causes Budd-Chiari syndrome, and IVC removal with a complex hepatectomy is required (Mingoli in J Am Coll Surg 211:145-146, 2010; Griffin in J Surg Oncol 34:53-60, 1987; Heaney in Ann Surg 163:237-241, 1966; Fortner in Ann Surg 180:644-652, 1974). METHODS: A 57-year-old male, without previous oncological history, presented with Budd-Chiari syndrome due to a leiomyosarcoma extending to the supra-diaphragmatic IVC and involving the right and middle hepatic veins. The patient did not receive neoadjuvant treatment. RESULTS: A femoral to superior vena cava veno-venous bypass was inserted, and both a median sternotomy and phreno-laparotomy with right subcostal extension were performed. A hemi-portocaval shunt was created between the right portal branch and the IVC, while a catheter was connected to the left portal branch for cold perfusion. Under extracorporeal circulation, the IVC was sectioned after infrahepatic and supra-diaphragmatic cross-clamping. The left liver was flushed with Celsior solution and packed with ice. A right trisectionectomy extended to the caudate lobe with en bloc vena cava removal was performed. The IVC was replaced by a cryopreserved aortic homograft, to which the stump of the left hepatic vein was anastomosed. Bypass duration, warm and cold liver ischemia, and operation time were 280 min, 8 min, 112 min, and 11 h, respectively. Duct-to-duct biliary anastomosis tutored by a T-tube was performed, and the patient was discharged on postoperative day 29, without major complications. After 16 months free of disease, the patient developed bilateral lung metastases. After 4 years the patient is still alive and receiving systemic chemotherapy. CONCLUSIONS: Leiomyosarcoma of the IVC involving the hepatic veins can be treated with extended hepatectomy and removal of the IVC through extracorporeal circulation.

RESUMO

OBJECTIVES: To evaluate the risk avoidance policy at liver transplant centers. BACKGROUND: Transplant center improvements have extended the indications for the sickest patients and the use of extended criteria donors (ECD). This may result in lower survival, perhaps paradoxically discouraging transplant centers from these procedures. We evaluated the outcome of recipients or donors refused by other transplant centers and transplanted by our transplant unit without risk avoidance policy. METHODS: Between 2007 and 2015, 616 patients underwent liver transplantation at our Unit; 142 patients (23%) had been rejected by other Italian centers, because of recipient selection (70 patients, 11%) or because of donor selection (78 patients, 12%), group A. Recipient and donor features were analyzed and compared with 474 patients transplanted in the same period, group B. RESULTS: Recipients were mainly rejected for comorbidity (19%), portal vein thrombosis (16%), previous surgery (9%), obesity (9%), and hepatocellular carcinoma (6%). Donors were rejected for HBcAb+ (33%), HCV+ (18%), liver biopsy (9%), HBsAg+ (6%), neoplastic (6%), or infective risk (5%).Most recipient and donor features were comparable between groups A and B.The 1- and 3-year overall graft and patient survival rates were similar in groups A and B and were comparable with national data. CONCLUSIONS: Recipients and donor grafts were rejected for reasons not accepted by scientific literature. They did not differ from control group patients and their postoperative outcome was comparable. These results highlight the discrepancy among transplant centers and the relevance of risk avoidance in LT policy.

RESUMO

BACKGROUND: Pancreatic cancer represents a fatal malignancy leading to premature death and loss of life expectancy. The aim of the present study was to assess how many years of life are lost due to this cancer, in relationship with surgery and ageing. METHODS: Data from 716 consecutive patients discharged from a tertiary referral hospital (2002-2012) with a diagnosis of pancreatic cancer and with complete clinical and follow-up data were used to estimate the number of years of life-lost (YLL) through a semi-parametric extrapolation having an age-, sex- and year-of-onset- matched population derived from national life tables as reference. RESULTS: The mean entire lifespan estimated for the 716 patients was 1.4 years (95% C.I.:0.8-1.9) resulting in a number of YLL after diagnosis of 12 years (95% C.I.:11.5-12.6) per person. Surgical patients (147 cases; 20.5%) were younger and experienced higher post-diagnostic lifespan (3.5 years) than non-surgical older individuals (0.8 years; p < 0.001). These figures were reflected on the number of expected YLL (EYLL) that remained substantially unaffected by surgery (p = 0.821). Patients aged ≤68 years experienced the highest number of EYLL (20.8 years); whereas elderly patients had a loss of life that corresponded to only 6% of the entire life they had already lived. CONCLUSIONS: In a typical pancreatic cancer cohort, surgery was not able to modify population-based statistics because of a different age at tumor onset which nullifies any benefit from a "lifespan from birth" perspective. Pancreatic cancer in younger individuals must be ranked within the very first causes of EYLL due to malignancy.
