RESUMEN
OBJECTIVE: To determine if lymph node yield (LNY) is associated with improved overall survival (OS) and time to recurrence (TTR) in patients with node-negative pancreatic ductal adenocarcinoma (PDAC) treated with neoadjuvant therapy (NAT). BACKGROUND: Lymph node yield has been associated with survival in solid gastrointestinal cancers, including PDAC. METHODS: Patients with pathological T stage I-III, node-negative (N0), PDAC treated with NAT followed by pancreatoduodenectomy were identified in the Massachusetts General Hospital (MGH) pancreatectomy database and the National Cancer Database (NCDB). A cutoff point of 22 nodes was identified in the NCDB using the point with the optimal (log-rank test) split. Overall survival and TTR were evaluated using univariate and multivariable analyses. RESULTS: In the MGH cohort, 233 node-negative patients following NAT were included. A LNY ≥ 22 was associated with prolonged median OS (59 months vs. 25 months, P<0.001) and prolonged TTR (32 months vs. 14 months, P=0.019). On multivariable analysis, LNY was an independent predictor of survival (HR 0.97, 95% CI 0.95-0.99, P=0.034) per sampled node. In the NCDB, 2,029 node-negative patients following NAT were included. A LNY ≥ 22 was associated with prolonged median OS (49 months vs. 33 months, P<0.001). On multivariable analysis, LNY was an independent predictor of survival (HR 0.99, 95% CI 0.98-0.99, P<0.001) per sampled node. CONCLUSION: Lymph node yield was associated with improved oncologic outcomes in patients treated with NAT followed by pancreatoduodenectomy in two independent datasets. Responsible mechanisms by which LNY impacts the outcomes of node-negative patients following NAT warrant further exploration.
RESUMEN
Objective: Our aim was to assess whether complications after pancreatoduodenectomy (PD) impact long-term quality of life (QoL) and functional outcomes. Background: There is an increasing number of long-term post-PD survivors, but few studies have evaluated long-term QoL outcomes. Methods: The EORTC QLQ-C30 and QLQ-PAN26 questionnaires were administered to patients who survived >5 years post-PD. Clinical relevance (CR) was scored as small (5-10), moderate (10-20), or large (>20). Patients were stratified based on whether they experienced a complication during the index hospitalization. Results: Of 305 patients >5 years post-PD survivors, with valid contact information, 248 completed the questionnaires, and 231 had complication data available. Twenty-nine percent of patients experienced a complication, of which 17 (7.4%) were grade 1, 27 (11.7%) were grade 2, and 25 (10.8%) were grade 3. Global health status and functional domain scores were similar between both groups. Patients experiencing complications reported lower fatigue (21.4 vs 28.1, P < 0.05, CR small) and diarrhea (15.9 vs 23.1, P < 0.05, CR small) symptom scores when compared to patients without complications. Patients experiencing complications also reported lower pancreatic pain (38.2 vs 43.4, P < 0.05, CR small) and altered bowel habits (30.1 vs 40.7, P < 0.01, CR moderate) symptom scores. There was a lower prevalence of worrying (36.2% vs 60.5%, P < 0.05) and bloating (42.0% vs 56.2%, P < 0.05) among PD survivors with complications. Conclusions: Post-PD complication rates were not associated with long-term global QoL or functionality, and may be associated with less severe pancreas-specific symptoms.
RESUMEN
Neuroendocrine neoplasms (NENs) are a diverse group of tumors with varying clinical behaviors. Their incidence has risen due to increased awareness, improved diagnostics, and aging populations. The 2019 World Health Organization classification emphasizes integrating radiology and histopathology to characterize NENs and create personalized treatment plans. Imaging methods like CT, MRI, and PET/CT are crucial for detection, staging, treatment planning, and monitoring, but each of them poses different interpretative challenges and none are immune to pitfalls. Treatment options include surgery, targeted therapies, and chemotherapy, based on the tumor type, stage, and patient-specific factors. This review aims to provide insights into the latest developments and challenges in NEN imaging, diagnosis, and management.
RESUMEN
OBJECTIVE: To investigate whether revision of pancreatic neck margin based on intraoperative frozen section analysis has oncologic value in post-neoadjuvant pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). SUMMARY BACKGROUND DATA: The role of intraoperative neck margin revision has been controversial, with little information specific to post-neoadjuvant PD. METHODS: Patients who underwent post-neoadjuvant PD (2013-2019) for conventional PDAC with frozen section analysis of neck margin at three academic institutions were included. Overall survival (OS) and recurrence-free survival (RFS) were compared across three groups: complete resection achieved en-bloc (CR-EB), complete resection achieved non-en-bloc (CR-NEB), and incomplete resection (IR). RESULTS: Among the 671 patients included, 524 (78.1%) underwent CR-EB, 119 (17.7%) CR-NEB and 28 (4.2%) IR. Patients undergoing CR-NEB and IR exhibited larger tumors and lower rates of RECIST response, requiring vascular resections more often. Likewise, CR-NEB and IR were associated with a worse pathological profile than CR-EB. The incidence of postoperative complications and access to adjuvant treatment were comparable among groups. A CR-EB was associated with the longest OS duration (34.3 mo). In patients with positive neck margin, obtaining a CR-NEB via re-excision was associated with a comparable OS relative to patients with an IR (26.9 vs. 27.1 mo, P=0.901). Similar results were observed for RFS. At multivariable analysis, neck margin status was not independently associated with survival and recurrence. CONCLUSION: Conversion of an initially positive pancreatic neck margin by additional resection is not associated with oncologic benefits in post-neoadjuvant PD and cannot be routinely recommended.
RESUMEN
BACKGROUND: The common hepatic artery lymph node (CHALN) represents a second-echelon node for tumors in the head of the pancreas. Although early studies suggested survival was comparable between the CHALN and remote metastasis in pancreatic ductal adenocarcinoma (PDAC), whether the lymph node is associated with adverse survival remains equivocal. Here, we examined a prospective cohort of patients calculating actual survival to better understand implications of this specific lymph node metastasis. METHODS: We studied 215 patients with pancreatic head PDAC, who underwent pancreaticoduodenectomies at a single institution between 2010 and 2017, wherein the CHALNs were excised. We performed actual and actuarial overall survival and disease-free survival (DFS) analyses, with subsequent univariate and multivariate analyses in node-positive patients. RESULTS: Of this cohort, 7.3% of patients had involvement of the CHALN, and all of them had metastatic spread to first-echelon nodes. Actual median survival of patients with no lymph node involvement was 49 months. In patients with any nodal involvement, the survival was no different when comparing the lymph node positive and negative (13 and 20 months, respectively). Univariate and multivariate analyses likewise attached no significance to the lymph node metastasis, while demonstrating worse survival with positive margin status and poorly differentiated histology. Our DFS analyses yielded similar results. CONCLUSION: We found no difference in actual survival in node-positive patients regardless of the CHALN involvement and recommended against its assessment in prognosticating survival or guiding surgical treatment.

BACKGROUND: Pancreatic cysts are often incidentally detected on routine imaging studies. Of these, mucinous cysts have a malignant potential. Several guidelines propose different management strategies, and implementation in patient care is inconsistent in the absence of dedicated infrastructure. METHODS: To address the challenges of pancreatic cyst diagnosis and management, we established a multidisciplinary pancreas cyst clinic (PCC) within our health system. This clinic encompasses both tertiary care academic centers and community hospitals, with leadership from surgical oncology, gastroenterology, and radiology. Our PCC's primary goal is to provide accurate diagnosis and tailored management recommendations for all patients with pancreatic cysts. Additionally, we maintain a prospective database to study the disease's natural history and the outcomes of various treatment strategies. CLINIC INFRASTRUCTURE: The clinic meets once per week for 45 min virtually via Zoom in the mornings. Patients are referred via electronic medical record (EMR) order, telephone call, or email from patient or referring provider. A dedicated advanced practice provider reviews referrals several times per day, calls patients to gather clinical data, ensures imaging is uploaded, and coordinates logistical aspects of the meeting during the dedicated time. Conferences are attended by representatives from surgery, radiology, medical pancreatology, and interventional gastroenterology. Each patient case is reviewed in detail and recommendations are submitted to referring providers and patients via an EMR message and letter. For patients requiring imaging surveillance, patients are followed longitudinally by the referring provider, gastroenterology team, or surgical team. For patients requiring endoscopic ultrasound (EUS) or surgical consultation, expedited referral to these services is made with prompt subsequent evaluation. RESULTS: A total of 1052 patients from our health system were evaluated between 2020 and 2021. Of these, 196 (18.6 %) underwent EUS, 41 (3.9 %) underwent upfront surgical resection, and the remainder were referred to gastroenterology (141-13.4 %), surgery (314-29.8 %), or back to their referring provider (597-56.7 %) for ongoing surveillance in collaboration with their primary care provider (PCP). Of cysts under surveillance, 61.3 % remained stable, 13.2 % increased in size, and 2 % decreased in size. A total of 2.3 % of patients were recommended to discontinue surveillance. CONCLUSIONS: The PCC provides infrastructure that has served to provide multidisciplinary review and consensus recommendations to patients with pancreatic cysts. This has served to improve the application of guidelines while providing individualized recommendations to each patient, while aiding non-expert referring providers throughout the region.

OBJECTIVE: To evaluate whether patient-controlled epidural analgesia (PCEA) improves postoperative pain during ambulation following elective open hepatectomy. BACKGROUND: Strategies to alleviate postoperative pain are a critical element of recovery after surgery. However, the optimal postoperative pain management strategy following open hepatectomy remains unclear. METHODS: We conducted a prospective, nonblinded, randomized comparison of PCEA (intervention) versus intravenous patient-controlled analgesia (IV PCA; control) for postoperative pain following elective open hepatectomy. The primary end point was pain during ambulation on postoperative day (POD) 2. The study was powered to detect a clinically significant 2-point difference on the pain numeric rating scale (NRS). Secondary end points included pain at rest, morbidity, time to return of bowel function, and length of stay. RESULTS: From 2015 to 2020, 231 patients were randomized (116 patients in the PCEA arm and 115 in the IV PCA arm). The incidence of epidural failure was 3% (n=4/116), with no epidural-related complications. Patients in the PCEA arm had a <2-point difference in NRS pain scores during ambulation on POD 2 vs. IV PCA (median 4.0 vs. 5.0, P <0.001). There was no difference in overall complications between the PCEA and IV PCA arms (33% vs. 40%, P =0.276). Secondary outcomes, including pain scores at rest, were similar between the study arms. CONCLUSIONS: PCEA was safe following open hepatectomy and was associated with a small difference in pain with activity on POD 2 that did not reach our pre-specified definition of clinical significance.

BACKGROUND: Colorectal cancer (CRC) is the second leading cause of cancer-related mortality in the United States (US); however, there are limited data on location of death in patients who die from CRC. We examined the trends in location of death and determinants in patients dying from CRC in the US. METHODS: We utilized the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database to extract nationwide data on underlying cause of death as CRC. A multinomial logistic regression was performed to assess associations between clinico-sociodemographic characteristics and location of death. RESULTS: There were 850,750 deaths due to CRC from 2003 to 2019. There was a gradual decrease in deaths in hospital, nursing home, or outpatient facility/emergency department over time and an increase in deaths at home and in hospice. Relative to White decedents, Black, Asian, and American Indian/Alaska Native decedents were less likely to die at home and in hospice compared with hospitals. Individuals with lower educational status also had a lower risk of dying at home or in hospice compared with in hospitals. CONCLUSIONS: The gradual shift in location of death of patients who die of CRC from institutionalized settings to home and hospice is a promising trend and reflects the prioritization of patient goals for end-of-life care by healthcare providers. However, there are existing sociodemographic disparities in access to deaths at home and in hospice, which emphasizes the need for policy interventions to reduce health inequity in end-of-life care for CRC.

BACKGROUND: Changes in tumor size and serum carbohydrate antigen 19-9 are commonly reported markers used to assess response to neoadjuvant therapy in pancreatic ductal adenocarcinoma. We evaluated the impact of the percentual tumor size reduction and carbohydrate antigen 19-9 kinetics on resectability and response to neoadjuvant FOLFIRINOX. METHODS: This was an institutional analysis of patients with non-metastatic (upfront resectable, borderline resectable, and locally advanced) pancreatic ductal adenocarcinoma who underwent neoadjuvant FOLFIRINOX. Resectability, pathologic response, disease recurrence, and overall survival were evaluated. RESULTS: Among 193 patients who completed FOLFIRINOX, 60% underwent resection, and 91% were R0. Pathologically, complete, and near-complete responses were achieved in 4% and 40% of patients, respectively. Tumor size reduction (odds ratio 1.02 per 1%, P = .024) and normalization of carbohydrate antigen 19-9 (odds ratio 2.61, P = .035) were associated with increased odds of resectability. Concerning pathologic response, tumor size reduction (odds ratio 1.03 per 1%, P = .018) was associated with increased odds of a complete and near-complete response. Lastly, in resected patients, a postoperative increase in carbohydrate antigen 19-9 after prior normalization after neoadjuvant therapy were at an increased risk of recurrence (hazard ratio 9.58, P < .001) and worse survival (hazard ratio 10.4, P < .001) compared to patients who maintained normalization. CONCLUSION: In patients with non-metastatic pancreatic ductal adenocarcinoma who underwent neoadjuvant therapy, tumor size reduction was a significant predictor of resectability and pathologic response, including complete and near complete responses, whereas serum carbohydrate antigen 19-9 normalization predicted resectability, disease recurrence, and survival. Patients with a postoperative carbohydrate antigen 19-9 rise after prior normalization after administration of neoadjuvant therapy were at an increased risk of recurrence and worse overall survival.

BACKGROUND: Using national registries, we aimed to evaluate oncologic textbook outcomes in pancreatic ductal adenocarcinoma patients. METHODS: Patients with stage I to III pancreatic ductal adenocarcinoma and surgical resection from 2010 to 2020 in the US and Germany were identified using the National Cancer Database and National Cancer Registries data. The surgical-oncologic textbook outcome was defined as complete oncologic resection with no residual tumor and ≥12 harvested lymph nodes. The composite endpoint was defined as surgical-oncologic textbook outcome and receipt of perioperative systemic and/or radiation therapy. RESULTS: In total, 33,498 patients from the National Cancer Database and 14,589 patients from the National Cancer Registries were included. In the National Cancer Database, 28,931 (86%) patients had complete oncologic resection with no residual tumor, and 11,595 (79%) in the National Cancer Registries. 8,723 (26%) patients in the National Cancer Database and 556 (4%) in the National Cancer Registries had <12 lymph nodes harvested. The National Cancer Database shows 26,135 (78%) underwent perioperative therapy and 8,333 (57%) in the National Cancer Registries. Surgical-oncologic textbook outcome was achieved in 21,198 (63%) patients in the National Cancer Database and in 11,234 (77%) patients from the National Cancer Registries. 16,967 (50%) patients in the National Cancer Database and 7,878 (54%) patients in the National Cancer Registries had composite textbook outcome. Median overall survival in patients with composite textbook outcomes was 32 months in the National Cancer Database and 27 months in the National Cancer Registries (P < .001). In contrast, those with non-textbook outcomes had a median overall survival of 23 months in the National Cancer Database and 20 months in the National Cancer Registries (P < .001). CONCLUSION: Surgical-oncologic textbook outcomes were achieved in > 50% of stage I to III pancreatic ductal adenocarcinoma for both the National Cancer Database and the National Cancer Registries. Failure to achieve textbook outcomes was associated with impaired survival across both registries.

OBJECTIVE: To investigate the oncological outcomes of patients with pancreatic ductal adenocarcinoma (PDAC) who had an R 0 or R 1 resection based on the revised R status (1 mm) after neoadjuvant therapy (NAT). BACKGROUND: The revised R status is an independent prognostic factor in upfront-resected PDAC; however, the significance of 1 mm margin clearance after NAT remains controversial. METHODS: Patients undergoing pancreatectomy after NAT for PDAC were identified from 2 prospectively maintained databases. Clinicopathological and survival data were analyzed. The primary outcomes were overall survival (OS), recurrence-free survival (RFS), and pattern of recurrence in association with R 0 >1 mm and R 1 ≤1 mm resections. RESULTS: Three hundred fifty-seven patients with PDAC were included after NAT and subsequent pancreatic resection. Two hundred eight patients (58.3%) received FOLFIRINOX, 41 patients (11.5%) received gemcitabine-based regimens, and 299 individuals (83.8%) received additional radiotherapy. R 0 resections were achieved in 272 patients (76.2%) and 85 patients (23.8%) had R 1 resections. Median OS after R 0 was 41.0 months, compared with 20.6 months after R 1 resection ( P = 0.002), and even longer after additional adjuvant chemotherapy ( R 0 44.8 vs R1 20.1 months; P = 0.0032). Median RFS in the R 0 subgroup was 17.5 months versus 9.4 months in the R 1 subgroup ( P < 0.0001). R status was confirmed as an independent predictor for OS ( R 1 hazard ratio: 1.56, 95% CI: 1.07-2.26) and RFS ( R 1 hazard ratio: 1.52; 95% CI: 1.14-2.0). In addition, R 1 resections were significantly associated with local but not distant recurrence ( P < 0.0005). CONCLUSIONS: The revised R status is an independent predictor of postresection survival and local recurrence in PDAC after NAT. Achieving R 0 resection with a margin of at least 1 mm should be a primary goal in the surgical treatment of PDAC after NAT.

BACKGROUND: Repurposing existing drugs for use in oncology is more efficient, cost-effective and safe than novel drug discovery. Calcium signalling is increasingly recognised to have a key role in chemoresistance. This study assessed the impact of calcium channel blockers (CCB) in pancreatic cancer. METHODS: Retrospective population study of patients undergoing resection (curative intent) of pancreatic ductal adenocarcinoma (SEER-Medicare, 2007-2017). Cox models were built to assess the impact on overall survival. As laboratory studies suggest a chemosensitising effect, the impact of CCB was assessed separately in patients receiving neoadjuvant chemotherapy. RESULTS: 6,223 patients were included, of whom 660 were prescribed CCB. In total, 591 received neoadjuvant chemotherapy; in this cohort CCB prescription was associated with improved overall survival when adjusting for multiple prognostic factors (aHR = 0.715, 0.514-0.996, P = 0.047). This effect was not observed in patients not receiving neoadjuvant chemotherapy (aHR = 1.082, 0.982-1.191, P = 0.112). CONCLUSION: CCB prescription was associated with improved overall survival in patients receiving neoadjuvant chemotherapy prior to pancreatic cancer resection. The association was specific to the group of patients receiving neoadjuvant chemotherapy, mirroring the chemosensitising effect in laboratory studies. This defines patients receiving neoadjuvant chemotherapy as a target population for prospective clinical trials of CCB in pancreatic cancer.

INTRODUCTION: The coronavirus pandemic has demonstrated profound issues with using the Internet to research health information. For patients recommended a complex operation, such as the Whipple pancreaticoduodenectomy, the quality of health information online has not been appraised. The objective of this study was to define the readability and content quality of YouTube search results for the Whipple pancreaticoduodenectomy. METHODS: The first 100 search results for "whipple procedure" less than 10 min long in English with audio and or text were transcribed. The Flesch-Kincaid Grade defined the reading grade level. High content quality videos were accredited by YouTube in accordance with principles specified by the National Academy of Medicine or mentioned the standard components for a surgical consent. The Anderson-Lau score is a composite of these consent criteria out of a maximum of 8/8. The simplicity of videos for patient education was defined by the DISCERN tool. RESULTS: The reading level of 23% of the top 100 search results met the American average (8th grade). Accreditation was present for 45% and associated with an earlier median search ranking (36 versus 68, P = 0.002) and more 5th-8th grade level material (70% versus 38%, P = 0.014). The median Anderson-Lau score was 3/8 (range = 0/8-7/8) with only 5% achieving 7/8. Only 4% were high quality per DISCERN. CONCLUSIONS: Although accredited videos were more readable, most videos, especially those targeting patients, were beyond the comprehension of the average American. Simpler and higher quality educational materials are needed to inform patients on Whipple pancreaticoduodenectomy beyond their date of clinical diagnosis or surgical consenting.

BACKGROUND: Communication between caregivers and clinical team members is critical for transitional care, but its quality and potential impact on outcomes are not well understood. This study reports on caregiver-reported quality of communication with clinical team members in the postpancreatectomy period and examines associations of these reports with patient and caregiver outcomes. METHODS: Caregivers of patients with pancreatic and periampullary malignancies who had undergone pancreatectomy were surveyed. Instrument measures assessed care experiences using the Caregiver Perceptions About Communication with Clinical Team Members (CAPACITY) instrument. The instrument has two main subscales: communication, assessing the extent to which providers helped caregivers comprehend details of clinical visits, and capacity, defined as the extent to which providers assessed whether caregivers were able to care for patients. RESULTS: Of 265 caregivers who were approached, 240 (90.6%) enrolled in the study. The mean communication and capacity subscale scores were 2.7 ± 0.6 and 1.5 ± 0.6, respectively (range, 0-4 [higher = better]). Communication subscale scores were lower among caregivers of patients who experienced (vs. those who did not experience) a 30-day readmission (2.6 ± 0.5 vs. 2.8 ± 0.6, respectively; p = .047). Capacity subscale scores were inversely associated with restriction in patient daily activities (a 0.04 decrement in the capacity score for every 1 point in daily activity restriction; p = .008). CONCLUSIONS: After pancreatectomy, patients with pancreatic and periampullary cancer whose caregivers reported worse communication with care providers were more likely to experience readmission. Caregivers of patients with greater daily activity restrictions were less likely to report being asked about the caregiver's skill and capacity by clinicians. PLAIN LANGUAGE SUMMARY: This prospective study used a validated survey instrument and reports on the quality of communication between health care providers and caregivers as reported by caregivers of patients with pancreatic and periampullary cancer after pancreatectomy. In an analysis of 240 caregivers enrolled in the study, lower communication scores (the extent to which providers helped caregivers understand clinical details) were associated with higher odds of 30-day patient readmission to the hospital. In addition, lower capacity scores (the extent to which providers assessed caregivers' ability to care for patients) were associated with greater impairment in caregivers. The strikingly low communication quality and capacity assessment scores suggest substantial room for improvement, with the potential to improve both caregiver and patient outcomes.

Background: Precision-Cut Liver Slices (PCLS) are an ex vivo culture model developed to study hepatic drug metabolism. One of the main benefits of this model is that it retains the structure and cellular composition of the native liver. PCLS also represents a potential model system to study liver fibrosis in a setting that more closely approximates in vivo pathology than in vitro methods. The aim of this study was to assess whether responses to antifibrotic interventions can be detected and quantified with PCLS. Methods: PCLS of 250 µm thickness were prepared from four different murine fibrotic liver models: choline-deficient, L-amino acid-defined, high-fat diet (CDAHFD), thioacetamide (TAA), diethylnitrosamine (DEN), and carbon tetrachloride (CCl4). PCLS were treated with 5 µM Erlotinib for 72 hours. Histology and gene expression were then compared with in vivo murine experiments and TGF-ß1 activated hepatic stellate cells (HSCs). These types of PCLS characterization were also evaluated in PCLS from human cirrhotic liver. Results: PCLS viability in culture was stable for 72 hours. Treatment of erlotinib, an EGFR inhibitor significantly inhibited the expression of profibrogenic genes Il6, Col1a1 and Timp1 in PCLS from CDAHFD-induced cirrhotic mice, and Il6, Col1a1 and Tgfb1 in PCLS from TAA-induced cirrhotic rats. Erlotinib treatment of PCLS from DEN-induced cirrhotic rats inhibited the expression of Col1a1, Timp1, Tgfb1 and Il6, which was consistent with the impact of erlotinib on Col1a1 and Tgfb1 expression in in vivo DEN-induced cirrhosis. Erlotinib treatment of PCLS from CCl4-induced cirrhosis caused reduced expression of Timp1, Col1a1 and Tgfb1, which was consistent with the effect of erlotinib in in vivo CCl4-induced cirrhosis. In addition, in HSCs at PCLS from normal mice, TGF-ß1 treatment upregulated Acta2 (αSMA), while treatment with erlotinib inhibited the expression of Acta2. Similar expression results were observed in TGF-ß1 treated in vitro HSCs. Expression of MMPs and TIMPs, key regulators of fibrosis progression and regression, were also significantly altered under erlotinib treatment in PCLS. Expression changes under erlotinib treatment were also corroborated with PCLS from human cirrhosis samples. Conclusion: The responses to antifibrotic interventions can be detected and quantified with PCLS at the gene expression level. The antifibrotic effects of erlotinib are consistent between PCLS models of murine cirrhosis and those observed in vivo and in vitro. Similar effects were also reproduced in PCLS derived from patients with cirrhosis. PCLS is an excellent model to assess antifibrotic therapies that is aligned with the principles of Replacement, Reduction and Refinement (3Rs).
RESUMEN
OBJECTIVE: We aimed to evaluate the safety and efficacy of NAT followed by surgical resection in patients with PDAC aged ≥75 years. SUMMARY BACKGROUND DATA: Whether administration of neoadjuvant therapy (NAT) followed by surgical resection in elderly patients with pancreatic ductal adenocarcinoma (PDAC) is safe and effective is unknown. METHODS: The present study is a three-part comparison of older (≥ 75 years) versus younger (< 75 years) patients in different settings throughout the continuum of PDAC care. The first analysis was a comparison of older versus younger consecutive patients with non-metastatic PDAC who were initiated on FOLFIRINOX. The second was a comparison of older vs. younger patients who underwent NAT followed by surgical resection, and the third and final analysis was a comparison of older patients who underwent either NAT followed by surgical resection vs. upfront surgical resection. Postoperative complications, overall survival (OS), and time to recurrence (TTR), were compared. Propensity-score matching (PSM) analysis was performed to adjust for potential confounders. RESULTS: In the first analysis, a lower proportion of older patients (n=40) were able to complete the intended neoadjuvant FOLFIRINOX (8) cycles compared to younger patients (n=214) (65.0% vs. 81.4%, P=0.021). However, older patients were just as likely to undergo surgical exploration as younger patients (77.5% vs 78.5%, P=0.89) as well as surgical resection (57.5% vs 55.6%, P=0.70). In the second analysis, PSM was conducted to compare older (n=54) vs. younger patients (n=54) who underwent NAT followed by surgical resection. There were no significant differences in postoperative complications between the matched groups. While there was a significant difference in overall survival (OS) between older and younger patients (median OS: 16.43 months vs. 30.83 months, P=0.002), importantly, there was no significant difference in time to recurrence (TTR, median: 7.65 months vs. 11.83 months, P=0.215). In the third analysis, older patients who underwent NAT followed by surgical resection (n=48) were compared with similar older patients who underwent upfront surgical resection (n=48). After PSM, there was a significant difference in OS (median OS: 15.78 months vs. 11.51 months, P=0.037) as well as TTR (median TTR: 8.81 months vs. 7.10 months, P=0.046) representing an association with improved outcomes that favored the neoadjuvant approach among older patients alone. CONCLUSIONS: This comprehensive three-part study showed that administration of NAT followed by surgical resection appears to be safe and effective among patients ≥ 75 years of age. An aggressive approach should be offered to older adults undergoing multimodal treatment of PDAC.
