RESUMO
OBJECTIVE: To evaluate the extent to which postoperative complications impact on patient health-related quality of life (HRQoL) and survival after pancreatic surgery. SUMMARY BACKGROUND DATA: Pancreatectomy is frequently associated with severe postoperative morbidity, which can affect patient recovery. Few and conflicting data are available regarding the effect of post-pancreatectomy complications on patient reported HRQoL. METHODS: This is an observational cohort study including consecutive patients enrolled in a prospective clinical trial (NCT04431076) who underwent elective pancreatectomy (2020-2022). Before surgery and on postoperative days (PODs) 15, 30, 90, 180, patients completed PROMIS-29 profile and Duke Activity Status Index questionnaires to assess their HRQoL and functional capacity. Mean differences in HRQoL scores were obtained using multivariable linear regression adjusting for preoperative scores and confounders. RESULTS: Of 528 patients, 370 (70%) experienced morbidity within 90 days, 154 (29%) severe complications (Clavien-Dindo grade >2). Delayed gastric emptying had the greatest impact on HRQoL, showing decreased mental health up to POD90 and physical health up to POD180 compared to uncomplicated patients. An inverse relationship between complication severity grade and HRQoL was evident for most domains, with Clavien-Dindo grade 3b-4 patients showing worse HRQoL and functional capacity scores up to 6 months after surgery. In 235 pancreatic cancer patients, grade 3b and 4 complications were associated with reduced disease specific survival (median 25 versus 41 mo, P<0.001). CONCLUSION: In patients undergoing pancreatic resection, postoperative complications significantly impact on all domains of patient quality of life with a dose-effect relationship between complication severity and impairment of HRQoL and functional capacity.
RESUMO
BACKGROUND: Limited data comparing recovery of health-related quality of life (HRQoL) after laparoscopic (LDP) versus open distal pancreatectomy (ODP) are available. The aim of this study was to assess the impact of laparoscopy on postoperative HRQOL after DP using the Patient-Reported Outcomes Measurement Information System (PROMIS). METHODS: Data from consecutive patients who underwent DP (2020-2022) enrolled in a prospective clinical trial were reviewed. Patients completed PROMIS-29 plus 2 profile preoperatively, at postoperative day (POD) 15, 30, 90, and 180. Linear regression analysis adjusting for confounders including preoperative PROMIS scores, age, gender, ASA score, diagnosis, and multivisceral resection was used to estimate mean between-group differences (MD) in postoperative PROMIS domains T scores. RESULTS: Overall, 202 patients (118 laparoscopic, 86 open) underwent DP (median age 66 years, pancreatic cancer 41%, multivisceral resection 10%, median LOS 6 days). At POD15, LDP was associated with higher physical function (MD 5.6) and participation in social roles and activities scores (MD 3.8), reduced fatigue (MD - 2.7) and sleep disturbance (MD - 3.8) compared to ODP. At POD30, LDP patients had higher physical function (MD 5.2) and participation in social roles and activities scores (MD 6.0), reduced fatigue (MD - 3.5), and anxiety (MD - 4.0) compared to ODP. No between-group differences were found in HRQoL domains at POD90 and 180. Six months after surgery, the proportions of patients who had not recovered to preoperative physical function, participation in social roles and activities, fatigue, pain interference, sleep disturbance, cognitive function, depression, and anxiety were 31%, 31%, 28%, 20%, 15%, 14%, 8%, and 7%, respectively. CONCLUSIONS: According to PROMIS, LDP resulted in improved physical and social functioning and reduced anxiety and fatigue up to 30 days after surgery compared to ODP. At 6 months after surgery, recovery of physical domains is still incomplete in up to 30% of patients.

OBJECTIVE: To contribute evidence for the reliability, construct validity, and responsiveness of the Patient-Reported Outcomes Measurement Information System 29 (PROMIS-29) profile questionnaire as a measure of recovery after pancreatic surgery. BACKGROUND: PROMIS questionnaires have been recommended to evaluate postdischarge recovery after surgery. Evidence supporting their measurement properties in pancreatic surgery is missing. METHODS: An observational validation study designed according to the COSMIN checklist was conducted including data from a prospective clinical trial. Patients undergoing pancreatectomy completed PROMIS-29 preoperatively and on postoperative days (PODs) 15, 30, 90, and 180. Reliability was assessed by internal consistency using Cronbach α. Construct validity was assessed by known-groups comparison. Responsiveness was evaluated hypothesizing that scores would be higher (1) preoperatively versus POD15, (2) on POD30 versus POD15, (3) on POD90 versus POD30, and (4) on POD180 versus POD90. RESULTS: Overall, 510 patients were included in the study. Reliability was good to excellent (α values ranged from 0.82 to 0.97). Data supported 4 of 5 hypotheses tested for construct validity for 5 domains (physical function, anxiety, depression, fatigue, and ability to participate in social roles) at most time points. Responsiveness hypotheses 1, 2, and 3 were supported by the data for physical function, fatigue, sleep disturbance, pain interference, and ability to participate in social roles domains. CONCLUSIONS: PROMIS had excellent reliability, discriminated between most groups expected to have different recovery trajectories and was responsive to the expected trajectory of recovery up to 90 days after surgery. Our findings support the use of PROMIS-29 profile as a patient-reported outcome measure of postdischarge recovery after pancreatectomy.

Patients requiring complex treatments, such as pancreatic surgery, may need to travel long distances and spend extended periods of time away from home, particularly when healthcare provision is geographically dispersed. This raises concerns about equal access to care. Italy is administratively divided into 21 separate territories, which are heterogeneous in terms of healthcare quality, with provision generally decreasing from north to south. This study aimed to evaluate the distribution of adequate facilities for pancreatic surgery, quantify the phenomenon of long-distance mobility for pancreatic resections, and measure its effect on operative mortality. Data refer to patients undergoing pancreatic resections (in the period 2014-2016). The assessment of adequate facilities for pancreatic surgery, based on volume and outcome, confirmed the inhomogeneous distribution throughout Italy. The migration rate from Southern and Central Italy was 40.3% and 14.6%, respectively, with patients mainly directed towards high-volume centers in Northern Italy. Adjusted mortality for non-migrating patients receiving surgery in Southern and Central Italy was significantly higher than that for migrating patients. Adjusted mortality varied greatly among regions, ranging from 3.2% to 16.4%. Overall, this study highlights the urgent need to address the geographical disparities in pancreatic surgery provision in Italy and ensure equal access to care for all patients.
RESUMO
BACKGROUND: It remains unclear whether preoperative body composition may affect the prognosis of pancreatic cancer patients undergoing surgery. The aim of the present study was to assess the extent to which preoperative body composition impacts on postoperative complication severity and survival in patients undergoing pancreatoduodenectomy for pancreatic ductal adenocarcinoma (PDAC). METHODS: A retrospective cohort study was performed on consecutive patients who underwent pancreatoduodenectomy with preoperative CT scan imaging available. Body composition parameters including total abdominal muscle area (TAMA), visceral fat area (VFA), subcutaneous fat area and liver steatosis (LS) were assessed. Sarcopenic obesity was defined as a high VFA/TAMA ratio. Postoperative complication burden was evaluated with the comprehensive complication index (CCI). RESULTS: Overall, 371 patients were included in the study. At 90 days after surgery, 80 patients (22%) experienced severe complications. The median CCI was 20.9 (IQR 0-30). At multivariate linear regression analysis, preoperative biliary drainage, ASA score ≥3, fistula risk score and sarcopenic obesity (37% increase; 95%CI 0.06-0.74; p = 0.046) were associated to an increase in CCI. Patient characteristics associated to sarcopenic obesity were older age, male gender and preoperative LS. At a median follow-up of 25 months (IQR 18-49), median disease-free survival (DFS) was 19 months (IQR 15-22). At cox-regression analysis, only pathological features were associated with DFS, while LS and other body composition measures did not show any prognostic role. CONCLUSION: The combination of sarcopenia and visceral obesity was significantly associated with increased complication severity after pancreatoduodenectomy for cancer. Patients' body composition did not affect disease free survival after pancreatic cancer surgery.
RESUMO
BACKGROUND: It is unclear whether routine postoperative admission to the intensive care unit (ICU) can improve outcomes for patients undergoing elective pancreatic surgery. Aim of the study was to determine preoperative and intraoperative predictors of unplanned ICU access in patients undergoing pancreatectomy treated within an established enhanced recovery pathway (ERP) and compare outcomes between direct and late ICU admission. METHODS: A retrospective observational study was conducted on adult patients who underwent pancreatic resection (2015-2019) within an ERP. Patients with preoperatively planned ICU admission were excluded from the study. Multiple multivariate logistic regression models were constructed to verify the association of preoperative and intraoperative variables with study outcomes. RESULTS: The study included 1486 consecutive patients (cancer diagnosis 60%, pancreaticoduodenectomy 60%; laparoscopic approach 20%; vascular resection 9%). Sixty-six (4.4%) patients had an unplanned ICU admission. Direct admission occurred in 22 (33%) patients and late ICU admission in 44 (67%) patients. Mortality was significantly lower in direct admission group (n = 3, 14%) compared to late admission (n = 25, 57%; p > 0.001). A comprehensive model including preoperative and intraoperative variables identified ASA score ≥ 3 (OR 5.59, p value < 0.001), history of hypertension (OR 2.29, p = 0.029), chronic obstructive pulmonary disease (OR 3.05, p = 0.026), proximal pancreatic resection (OR 2.79, p value 0.046), multivisceral resection (OR 8.86, p value < 0.001), high intraoperative blood loss (OR 1.01 per ml, p < 0.001), and increased serum lactate at the end of surgery (OR 1.25, p = 0.017) as independent factors associated with ICU admission. Area under the ROC curve was 0.891. CONCLUSION: Patient comorbidities, surgical complexity, and lactic acidosis at the end of surgery were associated with unplanned postoperative ICU admission. Late ICU admission had very high mortality rates compared to direct admission. Our findings suggest that patients with a combination of preoperative and intraoperative risk factors could benefit from upfront postoperative ICU admission to potentially improve postoperative outcomes.

BACKGROUND: Distal pancreatectomy is burdened by a high rate of clinically relevant postoperative pancreatic fistula (CR-POPF). The presence of a fistula-related abdominal collection often requires additional treatment such as antibiotics, percutaneous drainage, and endoscopic drainage thus prolonging patient recovery. Aim of this study was to describe the management of abdominal collections related to CR-POPF and identify variables associated with the need for invasive procedures. METHODS: A retrospective review of clinical data for patients who underwent distal pancreatectomy between 2015 and 2020 was conducted. All postoperative CT-scan imaging performed for clinical signs related to POPF was reviewed. The main outcome of the study was the need for procedural management (percutaneous or endoscopic) of CR-POPF-related fluid collections at 90 days after surgery. A multivariate regression analysis was adopted to analyze factors influencing procedural management of the collection. RESULTS: Five hundred sixteen patients were included in the study. Laparoscopic resection was performed in 290 patients (56%). At 90 days after surgery, CR-POPF occurred in 207 (40.1%) patients. A symptomatic collection related to fistula was observed in 130 patients (25.2%). Factors associated with fluid collections were increased body mass index (BMI) (25.5 versus 24, p = 0.001) and intraoperative blood loss (median of 250 versus 200 ml, p < 0.001). Procedural management was required in 70 patients (13.6%); 52 patients required interventional radiology and 18 endoscopic drainage. At multivariate analysis, risk factors for invasive procedures were the following CT-scan parameters: fluid collection diameter greater than 5 cm (OR 6.366, 95%CI 2.29-17.66, p = 0.001), presence of blood in the fluid collection (OR 10.618, 95%CI 1.94-58.09, p = 0.006), and enhancement of its walls (OR 4.073, 95%CI 1.22-13.57, p = 0.022). CONCLUSION: CR-POPF-related fluid collections affect about a quarter of patients undergoing distal pancreatectomy. CT-scan provides important information which can guide the management of the collection in a "step-up" fashion.

BACKGROUND: Limited data are available regarding the effect of preoperative biliary stent, during long-course neoadjuvant chemotherapy, on postoperative complications. The aim of the study is to analyze whether the association of neoadjuvant chemotherapy and biliary stent increases overall and infectious complications after pancreaticoduodenectomy. METHODS: Data for 538 consecutive pancreatic ductal adenocarcinoma patients who underwent pancreaticoduodenectomy between 2015 and 2020 were retrospectively analyzed. Four groups of patients were identified: neoadjuvant chemotherapy + biliary stent (171 patients), neoadjuvant chemotherapy-no biliary stent (65 patients), upfront surgery + biliary stent (184 patients), and upfront surgery-no biliary stent (118 patients). Median neoadjuvant chemotherapy duration was 6 months. The main outcome of the study was the occurrence of postoperative infections. RESULTS: No differences among the 4 groups were observed for pancreaticoduodenectomy-specific complications (ie, POPF, DGE, PPH). Infectious complications, in particular surgical site infections, were more frequent in neoadjuvant chemotherapy + biliary stent group (P = 0.001). At multivariate analysis, biliary stent was significantly associated with postoperative infectious complications in the overall cohort (odds ratio 1.996, confidence interval 95% 1.29-3.09, P = .002) and in neoadjuvant chemotherapy patients (odds ratio 5.974, 95% confidence interval 2.52-14.13, P < .001). Biliary stent significantly increased the comprehensive complication index by 9.5% (95% confidence interval 0.04-0.64, P = 0.024) in the overall cohort and 18.9% (95% confidence interval 0.22-1.23, P = .005) in the neoadjuvant chemotherapy group. The presence of multidrug-resistant microorganisms in intraoperative bile culture was not influenced by long-course neoadjuvant chemotherapy. CONCLUSION: In neoadjuvant chemotherapy patients, biliary stent increased the occurrence of postoperative infectious complications and surgical site infections, while the incidence of multidrug-resistant bacteria in intraoperative bile culture was similar between groups.

INTRODUCTION: Liver steatosis (LS) has been increasingly described in preoperative imaging of patients undergoing pancreaticoduodenectomy (PD). The aim of this study was to assess the impact of preoperative LS on complications after PD and identify possible contributors to LS development in this specific cohort. METHODS: Pancreatic head adenocarcinoma (PDAC) patients scheduled for PD, with preoperative CT-imaging available were included in the study. LS was defined as mean liver density lower than 45 Hounsfield units. Patients showing preoperative LS were matched for patient age, gender, BMI, ASA score, neoadjuvant treatment, and vascular and multivisceral resections, based on propensity scores in a 1:2 ratio to patients with no LS. The primary outcome was postoperative complication severity at 90 days as measured by the comprehensive complication index (CCI) RESULTS: Overall, 247 patients were included in the study. Forty-three (17%) patients presented with LS at preoperative CT-scan. After matching, the LS group included 37 patients, whereas the non-LS group had 74 patients. LS patients had a higher mean (SD) CCI, 29.7 (24.5) versus 19.5 (22.5), p = 0.035, and a longer length of hospital stay, median [IQR] 12 [8-26] versus 8 [7-13] days, p = 0.006 compared with non-LS patients. On multivariate analysis, variables independently associated with CCI were: LS (16% increase, p = 0.048), male sex (19% increase, p = 0.030), ASA score ≥ 3 (26% increase, p = 0.002), fistula risk score (FRS) (28% increase for each point of FRS, p = 0.001) and vascular resection (20% increase, p = 0.019). CONCLUSION: Preliminary evidence suggests that preoperative LS assessed by CT-scan influences complication severity in patients undergoing PD for PDAC.

BACKGROUND: Recent evidence suggests that pancreatic inflammation plays a pivotal role in the occurrence of clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy but few data are available for distal pancreatectomy (DP). The aim of this study was to evaluate the impact of early biochemical markers on the occurrence of CR-POPF after DP. METHODS: Clinical and laboratory data for 432 consecutive DP patients were reviewed. Serum amylase was evaluated on postoperative day (POD) 1, and drain fluid amylase (DFA) and C-reactive protein (CRP) were evaluated on POD 2 and 3. Receiver operator characteristic (ROC) curves were performed for all biochemical markers and an area under the curve (AUC) was computed. Multivariable regression analyses to identify the factors associated with CR-POPF and severe postoperative morbidity (Clavien-Dindo grade ≥ 3) were performed. RESULTS: At 90 days after surgery, CR-POPF occurred in 155 (36%) patients, severe complications in 66 (15%) patients. ROC curve analyses showed that DFA on POD2 had the largest AUC (0.753, p < 0.001), followed by serum amylase on POD 1 (0.651, p < 0.001), serum CRP on POD3 (0.644, p < 0.001), and CRP change between POD 2 and POD 3 (0.644, p < 0.001). Multivariable analysis identified male gender (OR 2.29, 95% CI 1.36-3.86; p = 0.002), DFA ≥ 1500 U/L on POD2 (OR 4.63, 95% CI 2.72-7.89; p < 0.001), serum amylase ≥ 100 U/L on POD 1 (OR 1.72, 95% CI 1.01-2.93; p = 0.046), and CRP increase by at least 25 mg/L on POD 3 compared to the previous day (OR 1.89, 95% CI 1.11-3.21; p = 0.019) as independent predictors of CR-POPF, yielding a valid regression model (AUC 0.765, 95% CI 0.714-0.816, p < 0.001). CONCLUSIONS: Postoperative serum amylase and CRP trajectory represent useful early biochemical markers for CR-POPF in addition to DFA. Our findings suggest that these laboratory tests should be incorporated into clinical practice to aid postoperative patient and drain management.

BACKGROUND: Grade B postoperative pancreatic fistula represents the largest fraction of postoperative pancreatic fistula. A subclassification of grade B postoperative pancreatic fistula has been recently proposed and seems to better stratify postoperative pancreatic fistula clinical and economic burden. Aim of this study was to validate, from a clinical and economic standpoint, grade B postoperative pancreatic fistula subclassification in patients submitted to pancreaticoduodenectomy. METHODS: All consecutive patients who underwent pancreaticoduodenectomy and developed biochemical leak or postoperative pancreatic fistula were included. Grade B postoperative pancreatic fistula was subclassified into 3 categories (B1: persistent drainage >21 days, B2: pharmacological treatments; B3: interventional procedures). Postoperative pancreatic fistula clinical and economic burden was assessed by evaluating postoperative complications, length of hospital stay, and overall hospital costs. RESULTS: Overall, 289 patients developed biochemical leak or postoperative pancreatic fistula. Of these, 34 had biochemical leak (12%), 25 had grade B1 postoperative pancreatic fistula (9%), 91 had grade B2 postoperative pancreatic fistula (31%), 94 had grade B3 postoperative pancreatic fistula (32%), and 45 experienced grade C postoperative pancreatic fistula (16%). The severity of postoperative complications significantly increased across biochemical leak and postoperative pancreatic fistula categories (P < .001), but it was comparable between biochemical leak and grade B1 postoperative pancreatic fistula. There was no significant difference in terms of length of hospital stay between patients with biochemical leak and those with grade B1 postoperative pancreatic fistula (P = 1.000). Overall hospital costs were similar for patients with biochemical leak and those with grade B1 postoperative pancreatic fistula (P = 1.000), whereas they significantly increased across all the other postoperative pancreatic fistula subgroups. CONCLUSION: A subclassification of grade B postoperative pancreatic fistula can better stratify the increasing clinical burden and economic impact of postoperative pancreatic fistula after pancreaticoduodenectomy. Grade B1 postoperative pancreatic fistula has minimal clinical and economic consequences and can be considered closer to a biochemical leak than to a grade B2 postoperative pancreatic fistula.

BACKGROUND: Preoperative anemia is a risk factor for blood transfusions and delayed postoperative recovery, but few data are available for pancreatic surgery. Aim of the study was to analyze the impact of preoperative anemia on outcomes after pancreatic resection. METHODS: Retrospective review of 1107 patients resected at San Raffaele Hospital (2015-2018). Preoperative anemia was defined as hemoglobin lower than 130 g/L for men and 120 g/L for women. Primary outcome was 90-day comprehensive complication index (CCI). Analysis was stratified according to type of surgery; proximal resections (pancreaticoduodenectomy and total pancreatectomy) versus distal pancreatectomy. RESULTS: In 776 proximal resection patients, preoperative anemia was associated with increased CCI (24 ± 25 vs. 19 ± 23, p = 0.018) and perioperative allogenic blood transfusions (n = 124, 46% vs. n = 129, 26%; p < 0.001). Multivariate analysis showed that anemia was associated with a 7% (95%CI 0.02-0.57 p = 0.047) increase in CCI, and was an independent factor associated with perioperative blood transfusion (OR 2.762, 95%CI 1.72-4.49, p < 0.001). In 331 distal pancreatectomies, anemia was not associated to increased morbidity but only to an increased risk of perioperative blood transfusion. CONCLUSION: Preoperative anemia is an independent risk factor for increased complication severity and blood transfusion in patients undergoing major pancreatic resection.

BACKGROUND: A fatty infiltration of the pancreas has been traditionally regarded as the main histological risk factor for postoperative pancreatic fistula, whereas the role of the secreting acinar compartment has been poorly investigated. The aim of this study was to evaluate the role of acinar content at the pancreatic resection margin in the development of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis after pancreaticoduodenectomy. METHODS: Data from 388 consecutive patients who underwent pancreaticoduodenectomy (2018-2019) were analyzed. Pancreatic section margins were histologically assessed for acinar, fibrosis, and fat content. Acinar content was categorized using median and third quartile as cut-offs. Univariate and multivariable analysis of possible predictors of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis were performed. RESULTS: Acinar content was <60% in 166 patients (42.8%), ≥60% and ≤80% in 156 patients (40.2%), and >80% in 66 patients (17.0%). The rate of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis was significantly higher in patients with acinar content >80% (39.4% and 33.3%, respectively) as well as in those with acinar content ≥60% and ≤80% (36.5% and 35.3%, respectively), compared with patients with acinar content <60% (10.2% and 5.4%, respectively) (P < .001). Acinar content was identified as an independent predictor of clinically relevant postoperative pancreatic fistula (≥60% and ≤80%, odds ratio 2.51, P = .008; >80%, odds ratio 2.93, P = .010) and clinically relevant postoperative acute pancreatitis (≥60% and ≤80%, odds ratio 9.42, P < .001; >80%, odds ratio 10.16, P < .001). CONCLUSION: An acinar content at the pancreatic resection margin ≥60% is associated to an increased risk of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis. Fat content was associated neither with clinically relevant postoperative pancreatic fistula nor with clinically relevant postoperative acute pancreatitis.

BACKGROUND: In bowel surgery, adherence to enhanced recovery program (ERP) has been associated with improved recovery. The objective of this study was to evaluate the impact of adherence to ERP elements on outcomes, and identify factors associated with successful recovery following distal pancreatectomy (DP). METHODS: Data for 376 patients who underwent DP managed within an ERP including 16 perioperative elements were reviewed. Primary endpoint was successful recovery, a composite outcome defined as length of hospital stay≤7 days, no severe complications nor readmissions. RESULTS: Patients had a mean (SD) overall adherence of 76 (14)%. Overall, 166 (44%) patients had a successful recovery. There was a positive association between overall adherence and successful recovery (OR 1.19, 95%CI 1.08-1.31 for every additional element, p = 0.001), while an inverse relationship was found with comprehensive complication index (8% reduction, 95%CI -15 to -2%, p = 0.011). Adherence to postoperative phase interventions had the greatest impact on recovery (OR 1.29, 95%CI 1.13-1.47 for every additional postoperative element; p < 0.001). At multivariable regression, early termination of IV fluids was the only ERP element associated with successful recovery (OR 2.80, 95%CI 1.73-4.54; p < 0.001). CONCLUSION: Increased adherence to ERP elements was associated with successful early recovery and reduction of postoperative complication severity.

The oncological benefit of achieving a negative pancreatic neck margin through re-resection after a positive frozen section (FS) is debated. Aim of this network meta-analysis is to evaluate the survival benefit of re-resection after intraoperative FS neck margin examination following pancreatectomy for ductal adenocarcinoma. A systematic search of studies comparing different strategies for the management of positive FS was performed. Patients were classified in three groups based on FS and permanent section (PS): Group A (FS-, PS-R0), Group B (FS+, PS-R0), Group C (FS±, PS-R1). A frequent random-effects network-meta-analysis was made reporting the surface under the cumulative ranking (SUCRA). Primary endpoint was overall survival (OS). Secondary endpoints were pathological outcomes. Seven retrospectives studies with 4205 patients were included and 99.1% of the pancreatic resections were pancreatoduodenectomies. Group A had the highest probability of better OS (SUCRA = 90%), compared to Group B (SUCRA = 48.7%) and Group C, which was the worst prognostic scenario (SUCRA = 11.3%). Group B had still a probability of longer OS compared to Group C (SUCRA = 48.7% vs 11.3%). Pathological features were more favourable in Group A, with the highest SUCRA for T1-T2 tumors (92.6%), N0 status (89.4%), absence of perineural invasion (92.3%). Heterogeneity was low (τ-value <0.1) for OS, and moderate (τ-values: 0.1-0.6) for pT, pN, and perineural invasion. In conclusion, negative neck margin after primary resection (FS negative) or re-resection of a positive FS was associated with improved survival compared with PS-R1. However, any intraoperative positive FS can be considered as a prognostic factor associated with a more aggressive disease.

BACKGROUND: The rate of patients with pancreatic ductal adenocarcinoma (PDAC) receiving neoadjuvant chemotherapy is increasing, but upfront resection is still offered to most patients with resectable or borderline resectable disease. Encouraging data reported in adjuvant chemotherapy trials prompts surgeons towards upfront surgery, but such trials are subject to a significant selection bias. This systematic review aims to summarize available high-quality evidence regarding survival of patients treated with upfront surgery for PDAC. METHODS: Pubmed, Cochrane, and Web of Science Databases were interrogated for prospective studies published between 2000 and 2021 that included at least a cohort of patients treated with upfront surgery for resectable or borderline resectable PDAC. The Cochrane Collaboration's risk-of-bias tool for randomized trials (RoB-2) was used to assess risk of bias in all randomized studies. Patient weighted median overall survival (OS) and disease-free survival (DFS) were calculated. RESULTS: Overall, 8,341 abstracts were screened, 17 reports were reviewed in full text, and finally 5 articles and 1 conference abstract underwent data extraction. Included studies were published between 2014 and 2021. All studies were RCTs comparing different neoadjuvant treatment strategies to upfront surgery. Three studies included only resectable PDAC patients, two studies recruited patients with resectable and borderline resectable disease, and one study selected only borderline resectable patients. A total of 439 patients were included in the upfront resection cohorts of the 6 studies, ranging between 20 to 180 patients per study. The weighted median OS after upfront surgery was 18.8 (95% CI 12.4 - 20.6) months. Median DFS was 9 (95% CI 1.6 - 12.5) months. Resection rate was 74.5% (range 65-90%). Adjuvant treatment was initiated in 68% (range 43-77%) of resected patients. CONCLUSIONS: High-quality data for PDAC patients undergoing upfront surgery is scarce. Meta-analysis from the included studies showed a significantly shorter OS and DFS compared to recently published studies focusing on adjuvant combination chemotherapy, suggesting that the latter may overestimate survival due to the exclusion of most patients scheduled for upfront surgery.
