RESUMEN
OBJECTIVES: The aim of this international multicentric study is to characterize postoperative hyperamylasemia (POH) after distal pancreatectomy (DP), with particular focus on its relationship with postoperative pancreatic fistula (POPF) occurrence and severity. BACKGROUND: The clinical relevance of POH after DP and its relationship with the occurrence and severity of POPF have not been explored yet. METHODS: All patients undergoing DP for any indication between 2015 and 2021 at three European referral Centers for pancreatic surgery were retrospectively analyzed. Drain fluid amylase (DFA), C-reactive protein (C-RP), and serum amylase were examined from postoperative-day (POD) 1 to 3. Biochemical leak (BL), POPF, POH, and post-pancreatectomy hemorrhage (PPH) were defined and graded according to ISGPS definitions. RESULTS: In total 1192 patients were included. Overall rates of POH and POPF were 18% (n= 210) and 29% (n= 344), respectively. The presence of DFA ≥2000 U/L on POD 1 (OR=2.11, 95% CI 1.68-2.86), C-RP ≥200 mg/L on POD 3 (OR=2.19, 95% CI 1.68-2.86), and POH (OR=1.58, 95% CI 1.14-2.19) were all independent early predictors of POPF (all P< 0.01). The presence of POH almost doubled the rate of POPF (43% vs. 26%, P<0.001), and higher POPF severity presented also higher POH rates (no POPF= 12%; BL= 19%; B POPF= 24%; C POPF= 52%). Among patients developing POPF, patients with POH had higher rates of PPH (22% vs 9%, P= 0.001), sepsis (24% vs 13%; P=0.011), re-operation (21% vs 8%; P< 0.01), and mortality (3% vs 0.3%; P= 0.025). CONCLUSIONS: The occurrence of POH is an early predictor of POPF and its severity after DP. The diagnosis of POH might define patients at higher risk for a complicated course, targeting them for prevention / mitigation strategies against pancreas specific complications.
RESUMEN
BACKGROUND: There are no established training pathways for hepato-pancreato-biliary (HPB) surgery in Europe. This study aims to overview the current status of fellowship training from both fellows' and institutions' perspectives. METHODS: A web-based snapshot survey was distributed to all members of the European-African Hepato-Pancreato-Biliary Association (E-AHPBA) to reach for former fellows and program directors of European HPB surgery fellowships held between 2013 and 2023. RESULTS: A total of 37 fellows and 13 program directors replied describing 32 different programs in 13 European countries. The median (range) age at fellowship start was 34 (30-45 years). Fellowship duration was most commonly one (36 %) or two (40 %) years. Fellowships were funded in 70 % and fellows were required to learn a new language in 27 %. Most fellows performed between none and 10 pancreatic (68 %), major (67 %) and minor (60 %) liver resections as 1st surgeon, while the number of operations performed as 1st assistant were more heterogeneous. Program directors estimated a higher number of operations performed by fellows as first surgeons. The percentage of procedures performed minimally invasively did not exceed 10 %. CONCLUSION: There is substantial heterogeneity between HPB fellowship programs in Europe. A wider standardization of clinical curriculum, including minimally invasive surgery, is desirable.

BACKGROUND: International guidelines on intraductal papillary mucinous neoplasm (IPMN) recommend a formal oncological resection including splenectomy when distal pancreatectomy is indicated. This study aimed to compare oncological and surgical outcomes after distal pancreatectomy with or without splenectomy in patients with presumed IPMN. METHODS: An international, retrospective cohort study was undertaken in 14 high-volume centres from 7 countries including consecutive patients after distal pancreatectomy for IPMN (2005-2019). Patients were divided into spleen-preserving distal pancreatectomy (SPDP) and distal pancreatectomy with splenectomy (DPS). The primary outcome was lymph node metastasis (LNM). Secondary outcomes were overall survival, duration of operation, blood loss, and secondary splenectomy. RESULTS: Overall, 700 patients were included after distal pancreatectomy for IPMN; 123 underwent SPDP (17.6%) and 577 DPS (82.4%). The rate of malignancy was 29.6% (137 patients) and the overall rate of LNM 6.7% (47 patients). Patients with preoperative suspicion of malignancy had a LNM rate of 17.2% (23 of 134) versus 4.3% (23 of 539) among patients without suspected malignancy (P < 0.001). Overall, SPDP was associated with a shorter operating time (median 180 versus 226â min; P = 0.001), less blood loss (100 versus 336â ml; P = 0.001), and shorter hospital stay (5 versus 8 days; P < 0.001). No significant difference in overall survival was observed between SPDP and DPS for IPMN after correction for prognostic factors (HR 0.50, 95% c.i. 0.22 to 1.18; P = 0.504). CONCLUSION: This international cohort study found LNM in 6.7% of patients undergoing distal pancreatectomy for IPMN. In patients without preoperative suspicion of malignancy, SPDP seemed oncologically safe and was associated with improved short-term outcomes compared with DPS.

OBJECTIVE: To assess the correlation between pancreatic quantitative edge analysis as a surrogate of parenchymal stiffness and the incidence of postoperative pancreatic fistula (POPF), in patients undergoing pancreaticoduodenectomy (PD). METHODS: All consecutive patients who underwent PD at our Institution between March 2018 and November 2019 with an available preoperative CT were included. Pancreatic margin score (PMS) was calculated through computer-assisted quantitative edge analysis on the margins of the pancreatic body and tail (the expected pancreatic remnant) on non-contrast scans with in-house software. Intraoperative assessment of pancreatic stiffness by manual palpation was also performed, classifying pancreatic texture into soft and non-soft. PMS values were compared between groups using an unpaired T-test and correlated with the intraoperative evaluation of stiffness and with the grading of postoperative pancreatic fistula according to the International Study Group on Pancreatic Surgery (ISGPS). RESULTS: Patient population included 200 patients (mean age 64.6 years), 146 without onset of POPF (73%, non-POPF group), and 54 with POPF (27%, POPF group). A significant difference in PMS values was observed between POPF and non-POPF (respectively 1.88 ± 0.05 vs 0.69 ± 0.01; p < 0.0001). PMS values of pancreatic parenchymas intraoperatively considered "soft" were significantly higher than those evaluated as "non-soft" (1.21 ± 0.04 vs 0.73 ± 0.02; p < 0.0001). A significant correlation between PMS values and POPF grade was observed (r = 0.8316), even in subgroups of patients with soft (r = 0.8016) and non-soft (r = 0.7602) pancreas (all p < 0.0001). CONCLUSIONS: Quantitative edge analysis with dedicated software may stratify patients with different pancreatic stiffness, thus potentially improving preoperative risk assessment and strategies for POPF mitigation. CLINICAL RELEVANCE STATEMENT: This study proposes quantitative pancreas edge analysis as a predictor for postoperative pancreatic fistula. The test has high accuracy and correlation with fistula grade according to the International Study Group on Pancreatic Surgery. KEY POINTS: ⢠Prediction of postoperative pancreatic fistula (POPF) onset risk after pancreaticoduodenectomy is based only on intraoperative evaluation. ⢠Quantitative edge analysis may preoperatively identify patients with higher risk of POPF. ⢠Quantification of pancreatic stiffness through the analysis of pancreatic margins could be done on preoperative CT.

BACKGROUND: A wrong diagnosis of nature is common in pancreatic cystic neoplasms. The aim of the current study is to reappraise the diagnostic errors for presumed pancreatic cystic neoplasms in patients undergoing surgery. METHODS: All pancreatic resections for presumed pancreatic cystic neoplasms following international guidelines between 2011 and 2020 were analyzed. Misdiagnosis was defined as the discrepancy between preoperative diagnosis of nature and final pathology. Mismatch was defined as the discrepancy between the preoperative suspect of malignancy (or its absence) and final pathology. RESULTS: A total of 601 patients were included. Endoscopic ultrasound was performed in 301 (50%) patients. Overall misdiagnosis and mismatch were 19% and 34%, respectively, with no significant benefit for those patients who underwent endoscopic ultrasound. The highest rate of misdiagnosis was reached for cystic neuroendocrine tumors (61%) and the lowest for solid pseudopapillary tumors (6%). Several diagnostic errors had clinical relevance, including 7 (13%) presumed serous cystic neoplasms eventually found to be other malignant entities, 50 (24%) intraductal papillary mucinous neoplasms with high-risk stigmata revealed to be non-malignant, and 38 (33%) intraductal papillary mucinous neoplasms without high-risk stigmata revealed to be malignant at final pathology. A preoperative presumption of malignant mucinous cystic neoplasm was correct in only 20 (16%) patients. CONCLUSIONS: Despite not always being clinically relevant, diagnostic errors are still common among resected pancreatic cystic neoplasms when applying international guidelines. New diagnostic tools beyond endoscopic ultrasound are needed to refine the diagnosis of those lesions at higher risk for unnecessary surgery or accidentally observed, nevertheless being malignant.

BACKGROUND: Pancreatic surgery is increasingly moving towards centralization in high-volume centres, supported by evidence on the volume-outcome relationship. At the same time, minimally invasive pancreatic surgery is becoming more and more established worldwide, and interest in new techniques, such as robotic pancreatoduodenectomy, is growing. Such recent innovations are reshaping modern pancreatic surgery, but they also represent new challenges for surgical training in its current form. METHODS: This narrative review presents a chosen selection of literature, giving a picture of the current state of training in pancreatic surgery, together with the authors' own views, and in the context of centralization and innovation towards minimally invasive techniques. RESULTS: Centralization of pancreatic surgery at high-volume centres, volume-outcome relationships, innovation through minimally invasive technologies, learning curves in both traditional and minimally invasive surgery, and standardized training paths are the different, but deeply interconnected, topics of this article. Proper training is essential to ensure quality of care, but innovation and centralization may represent challenges to overcome with new training models. CONCLUSION: Innovations in pancreatic surgery are introduced with the aim of increasing the quality of care. However, their successful implementation is deeply dependent on dissemination and standardization of surgical training, adapted to fit in the changing landscape of modern pancreatic surgery.

BACKGROUND: Chronic kidney disease is a prevalent condition in surgical patients. Possible associations with increased postoperative morbidity and mortality have not been clearly demonstrated in patients undergoing pancreatoduodenectomy. The aim of this study was to assess the risk of postoperative complications in patients with reduced kidney function undergoing pancreatoduodenectomy. METHODS: All patients undergoing pancreatoduodenectomy at Karolinska University Hospital between 2008 and 2019 were retrospectively included. The variable of interest was chronic kidney disease, based on preoperative estimated glomerular filtration rate measurements. Unadjusted and adjusted logistic regression analyses were performed for standardized postoperative complications. RESULTS: A total of 971 patients were included in the study, of whom 92 (10%) had an estimated glomerular filtration rate < 60 mL/min/1.73m2 , equivalent to chronic kidney disease Stage 3a or worse. Patients with chronic kidney disease had a higher odds of longer hospital stay (adjusted odds ratio 1.58, 95% confidence interval 1.00-2.50) and postoperative weight increase (adjusted odds ratio 2.02, 1.14-3.56). A 10 unit increase of preoperative estimated glomerular filtration rate was associated to lower odds of intensive care unit admission (adjusted odds ratio 0.81, 0.69-0.95), delayed gastric emptying (adjusted odds ratio 0.90, 0.81-0.99), and post-operative pancreatic fistula (adjusted odds ratio 0.83, 0.74-0.94). CONCLUSION: Patients undergoing pancreatoduodenectomy with decreased preoperative kidney function are more likely to experience major postoperative complications, and also postoperative weight increase. Preoperative kidney function assessment is important in risk stratification before pancreatoduodenectomies.

BACKGROUND: Early stratification of postoperative pancreatic fistula according to severity and/or need for invasive intervention may improve outcomes after pancreaticoduodenectomy. This study aimed to identify the early postoperative variables that may predict postoperative pancreatic fistula severity. METHODS: All patients diagnosed with biochemical leak and clinically relevant-postoperative pancreatic fistula based on drain fluid amylase >300 U/L on the fifth postoperative day after pancreaticoduodenectomy were identified from a consecutive cohort from Birmingham, UK. Demographics, intraoperative parameters, and postoperative laboratory results on postoperative days 1 through 7 were retrospectively extracted. Independent predictors of clinically relevant-postoperative pancreatic fistula were identified using multivariable binary logistic regression and converted into a risk score, which was applied to an external cohort from Verona, Italy. RESULTS: The Birmingham cohort had 187 patients diagnosed with postoperative pancreatic fistula (biochemical leak: 99, clinically relevant: 88). In clinically relevant-postoperative pancreatic fistula patients, the leak became clinically relevant at a median of 9 days (interquartile range: 6-13) after pancreaticoduodenectomy. Male sex (P = .002), drain fluid amylase-postoperative day 3 (P < .001), c-reactive protein postoperative day 3 (P < .001), and albumin-postoperative day 3 (P = .028) were found to be significant predictors of clinically relevant-postoperative pancreatic fistula on multivariable analysis. The multivariable model was converted into a risk score with an area under the receiver operating characteristic curve of 0.78 (standard error: 0.038). This score significantly predicted the need for invasive intervention (postoperative pancreatic fistula grades B3 and C) in the Verona cohort (n = 121; area under the receiver operating characteristic curve: 0.68; standard error = 0.06; P = .006) but did not predict clinically relevant-postoperative pancreatic fistula when grades B1 and B2 were included (area under the receiver operating characteristic curve 0.52; standard error = 0.07; P = .802). CONCLUSION: We developed a novel risk score based on early postoperative laboratory values that can accurately predict higher grades of clinically relevant-postoperative pancreatic fistula requiring invasive intervention. Early identification of severe postoperative pancreatic fistula may allow earlier intervention.

BACKGROUND: Pancreatic acinar content (Ac) has been associated with pancreas-specific complications after pancreatoduodenectomy. The aim of this study was to improve the prediction ability of intraoperative risk stratification by integrating the pancreatic acinar score. METHODS: A training and validation cohort underwent pancreatoduodenectomy with a subsequent histologic assessment of pancreatic section margins for Ac, fibrosis (Fc), and fat. Intraoperative risk stratification (pancreatic texture, duct diameter) and pancreas-specific complications (postoperative hyperamylasemia [POH], postpancreatectomy acute pancreatitis [PPAP], pancreatic fistula [POPF]) were classified according to ISGPS definitions. RESULTS: In the validation cohort (n= 373), the association of pancreas-specific complications with higher Ac and lower Fc was replicated (all P <0.001). In the entire cohort (n= 761), the ISGPS classification allocated 275 (36%) patients into intermediate-risk classes B (POH 32%/PPAP 3%/POPF 17%) and C (POH 36%/PPAP 9%/POPF 33%). Using the acinar score (Ac ≥60% and/or Fc ≤10%), intermediate-risk patients could be dichotomized into a low-risk (POH 5%/PPAP 1%/POPF 6%) and a high-risk (POH 51%/PPAP 9%/POPF 38%) group (all P <0.001). The acinar score AUC for POPF prediction was 0.70 in the ISGPS intermediate-risk classes. Overall, 239 (31%) patients were relocated into the high-risk group from lower ISGPS risk classes using the acinar score. CONCLUSIONS: The risk of pancreas-specific complications appears to be dichotomous-either high or low-according to the acinar score, a tool to better target the application of mitigation strategies in cases of intermediate macroscopic features.

The overall prevalence of pancreatic cysts (PCs) is high in the general population. In clinical practice PCs are often incidentally discovered and are classified into benign, premalignant, and malignant lesions according to the World Health Organization. For this reason, in the absence of reliable biomarkers, to date clinical decision-making relies mostly on risk models based on morphological features. The aim of this narrative review is to present the current knowledge regarding PC's morphologic features with related estimated risk of malignancy and discuss available diagnostic tools to minimize clinically relevant diagnostic errors.

Pancreaticoduodenectomy (PD) is a mainstay in the management of periampullary tumors. Treatment algorithms increasingly employ a multimodal strategy, which includes neoadjuvant and adjuvant therapies. However, the successful treatment of a patient is contingent on the execution of a complex operation, whereby minimizing postoperative complications and optimizing a fast and complete recovery are crucial to the overall success. In this setting, risk reduction and benchmarking the quality of care are essential frameworks through which modern perioperative PD care must be delivered. The postoperative course is primarily influenced by pancreatic fistulas, but other patient- and hospital-associated factors, such as frailty and the ability to rescue from complications, also affect the outcomes. A comprehensive understanding of the factors influencing surgical outcomes allows the clinician to risk stratify the patient, thereby facilitating a frank discussion of the morbidity and mortality of PD. Further, such an understanding allows the clinician to practice based on the most up-to-date evidence. This review intends to provide clinicians with a roadmap to the perioperative PD pathway. We review key considerations in the pre-, intra-, and post-operative periods.
RESUMEN
The aim of this study is to describe the current utilization of artificial nutrition [enteral (EN) or total parenteral (TPN)] for pancreatic fistula (POPF) after pancreatoduodenectomy (PD). Prospective data of 311 patients who consecutively underwent PD at a tertiary referral center for pancreatic surgery were collected. Data included the use of EN or TPN specifically for POPF treatment, including timing, outcomes, and adverse events related to their administration. POPF occurred in 66 (21%) patients and 52 (79%) of them were treated with artificial nutrition, for a median of 36 days. Forty (76%) patients were treated with a combination of TPN and EN. The median day of artificial nutrition start was postoperative day 7, with a median drain output of 180 cc/24 h. In 33 (63%) patients, artificial nutrition was started while only a biochemical leak was ongoing. Fungal infections and catheter-related bloodstream infection occurred in 13 (28%) and 15 (33%) TPN patients, respectively; among EN patients, 19 (41%) experienced diarrhea not responsive to pancreatic enzymes and 9 (20%) needed multiple endoscopic naso-jejunal tube positioning. The majority of the patients developing POPF after PD were treated with a combination of TPN and EN, with a clinically relevant rate of adverse events related to their administration. Standardization of nutrition routes in patients developing POPF is urgently needed.

OBJECTIVE: To provide an overview of the current practice of intraoperative blood loss (BL) estimation in hepato-pancreato-biliary (HPB) surgery. BACKGROUND: Intraoperative BL is a major quality marker in HPB surgery and a predictor of perioperative outcomes. However, the method for BL estimation is not standardized. METHODS: A systematic review was performed of original studies published between 2006 and 2021 reporting the intraoperative BL of patients undergoing pancreatic or hepatic resections. A web-based snapshot survey was distributed globally to all members of the International Hepato-Pancreato-Biliary Association (IHPBA). RESULTS: A total of 806 studies were included; 480 (60%) had BL as their primary outcome, and 105 (13%) had BL as their secondary outcome. However, 669 (83%) did not specify how BL estimation was performed, and 9 different methods were found among the remaining 136 (17%) studies.The survey was completed by 252 surgeons. Most of the responders (94%) declared that they systematically performed BL estimation and considered BL predictive of postoperative complications after pancreatic (73%) and liver (74%) resection. All methods previously identified in the literature were used by responders with different frequencies. A calculation based on suction fluid amounts, operative gauze weight, and irrigation was the most used method in the literature (7%) and among responders (51%). Most responders (83%) felt that BL estimation in HPB surgery needs improved standardization. CONCLUSIONS: Standardization of intraoperative BL estimation is urgently needed in HPB surgery to ensure the consistency of reporting and reproducibility.

OBJECTIVE: To evaluate whether postoperative serum hyperamylasemia (POH), with drain fluid amylase (DFA) and C-reactive protein (CRP), improves the Fistula Risk Score (FRS) accuracy in assessing the risk of a postoperative pancreatic fistula (POPF). SUMMARY BACKGROUND DATA: The FRS predicts POPF occurrence using intraoperative predictors with good accuracy but intrinsic limits. METHODS: Outcomes of patients who underwent pancreaticoduodenectomies between 2016 and 2021 were evaluated across FRS-risk zones and POH occurrence. POH consists of serum amylase activity greater than the upper limit of normal (52 U/l), persisting within the first 48 hours postoperatively (postoperative day -POD- 1 and 2). RESULTS: Out of 905 pancreaticoduodenectomies, some FRS elements, namely soft pancreatic texture (odds ratio (OR) 11.6), pancreatic duct diameter (OR 0.80), high-risk pathologic diagnosis (OR 1.54), but not higher blood loss (OR 0.99), were associated with POH. POH was an independent predictor of POPF, which occurred in 46.8% of POH cases ( P <0.001). Once POH occurs, POPF incidence rises from 3.8% to 42.9%, 22.9% to 41.7%, and 48.9% to 59.2% in patients intraoperatively classified at low, moderate and high FRS risk, respectively. The predictive ability of multivariable models adding POD 1 drain fluid amylase, POD 1-2 POH and POD 3 C-reactive protein to the FRS showed progressively and significantly higher accuracy (AUC FRS=0.82, AUC FRS-DFA=0.85, AUC FRS-DFA-POH=0.87, AUC FRS-DFA-POH-CRP=0.90, DeLong always P <0.05). CONCLUSIONS: POPF risk assessment should follow a dynamic process. The stepwise retrieval of early, postoperative biological markers improves clinical risk stratification by increasing the granularity of POPF risk estimates and affords a possible therapeutic window before the actual morbidity of POPF occurs.

BACKGROUND: Pancreatic cancer is notorious for its aggressive nature and low survival rate, with less than 10% of patients surviving beyond five years. Early detection is difficult, but skin metastases can be a rare but significant indicator. This systematic review focuses on the epidemiology, clinical features, and histology of skin metastases from pancreatic cancer to determine their importance in early diagnosis and overall management of the disease. MATERIALS AND METHODS: Following PRISMA guidelines, we conducted an exhaustive search of MEDLINE/PubMed, EMBASE, and SCOPUS databases up to June 2023, using specific keywords. Four independent investigators screened the studies using predefined criteria, and two investigators checked the accuracy and consistency of the data extraction. We assessed the quality of the trials using adapted criteria from the Joanna Briggs Institute. A narrative synthesis rather than a meta-analysis was chosen because of the different study designs. RESULTS: The final analysis included 57 patients with skin metastases from pancreatic cancer. Cutaneous metastases, although rare, presented with approximately equal gender distribution and a mean age of 63.4 years. Predominantly non-umbilical (77%), these metastases showed clinical diversity, ranging from asymptomatic nodules to painful or ulcerated lesions. Notably, skin metastases often preceded the diagnosis of primary pancreatic cancer (58%). Primary tumor characteristics revealed different localizations, with adenocarcinoma being the most prevalent histological type (77%). A significant association (p = 0.008) was observed between pancreatic tumor location and the timing of presentation of skin metastases. Tumors located in the body and tail of the pancreas were more likely to manifest skin metastases as an initial clinical manifestation (62.2%) than those in the head of the pancreas (20.8%). CONCLUSIONS: In conclusion, although skin metastases are rare, they are important indicators of pancreatic cancer, highlighting the need for multidisciplinary healthcare collaboration and thorough skin examination. Recognizing them could lead to earlier diagnosis, which is crucial in a cancer with limited treatment options.
RESUMEN
OBJECTIVES: This study aims to assess the prevalence of preoperative fatigue, depression and anxiety among patients undergoing pancreatic surgery for pancreatic cancer (PC), and possible relationship with postoperative outcomes. METHODS: Prospective data from 162 consecutive patients undergoing pancreatectomy for PC at a third-level referral centers for pancreatic surgery were collected. All patients preoperatively completed four questionnaires assessing depression (PHQ-9), anxiety (STAI-Y2), chronic illness fatigue (FACIT-F) and cancer therapy fatigue (FACT-G). RESULTS: Forty patients (25%) where in the first quartile for chronic illness (FACIT-F ≤34) and/or cancer therapy (FACT-G ≤78) fatigue, 26 patients (16%) met the criteria for major depression (PHQ-9 ≥10) and 34 patients (21%) had anxiety symptoms (STAI-Y2 ≥40). Cancer therapy fatigue was significantly associated with higher rates of morbidity (70% vs 49%), major morbidity (Clavien-Dindo ≥3) (28% vs 11%), post-pancreatectomy hemorrhage (18% vs 4%), pulmonary complications (20% vs 9%) and mortality (8% vs null) (all P ≤ 0.01). Major depression was associated with higher rates of post-pancreatectomy hemorrhage and readmission (23% vs 5%). Multivariable logistic regression analysis of preoperative factors confirmed diabetes (OR 2.71, 95%CI 1.01-7.20; P = 0.04), ASA score ≥3 (OR 4.12, 95%CI 1.52-11.21; P < 0.01) and cancer therapy fatigue (OR 2.95, 95%CI 1.01-8.74; P = 0.04) to be independent predictors of major morbidity. CONCLUSIONS: Higher levels of fatigue (in particular cancer therapy fatigue) strongly correlates with worse postoperative outcomes.

BACKGROUND: This study aimed to determine the clinical relevance of putative radiographic and serologic metrics of chemotherapy response in patients with localized pancreatic cancer (LPC) who do not undergo pancreatectomy. Studies evaluating the response of LPC to systemic chemotherapy have focused on histopathologic analyses of resected specimens, but such specimens are not available for patients who do not undergo resection. We previously showed that changes in tumor volume and CA 19-9 levels provide a clinical readout of histopathologic response to preoperative therapy. METHODS: Our institutional database was searched for patients with LPC who were treated with first-line chemotherapy between January 2010 and December 2017 and did not undergo pancreatectomy. Radiographic response was measured using RECIST 1.1 and tumor volume. The volume of the primary tumor was compared between pretreatment and posttreatment images. The percentage change in tumor volume (%Δvol) was calculated as a percentage of the pretreatment volume. Serologic response was measured by comparing pretreatment and posttreatment CA 19-9 levels. We established 3 response groups by combining these metrics: (1) best responders with a decline in %Δvol in the top quartile and in CA 19-9, (2) nonresponders with an increase in %Δvol and in CA 19-9, and (3) other patients. RESULTS: This study included 329 patients. Individually, %Δvol and change in CA 19-9 were associated with overall survival (OS) (P≤.1), but RECIST 1.1 was not. In all, 73 patients (22%) were best responders, 42 (13%) were nonresponders, and there were 214 (65%) others. Best responders lived significantly longer than nonresponders and others (median OS, 24 vs 12 vs 17 months, respectively; P<.01). A multivariable model adjusting for type of chemotherapy regimen, number of chemotherapy doses, and receipt of radiotherapy showed that best responders had longer OS than did the other cohorts (hazard ratio [HR], 0.35; 95% CI, 0.21-0.58 for best responders, and HR, 0.55; 95% CI, 0.37-0.83 for others). CONCLUSIONS: Changes in tumor volume and serum levels of CA 19-9-but not RECIST 1.1-represent reliable metrics of response to systemic chemotherapy. They can be used to counsel patients and families on survival expectations even if pancreatectomy is not performed.
