RESUMO

OBJECTIVE: The objective of the current study was to characterize the role of patient social vulnerability relative to hospital racial/ethnic integration on postoperative outcomes among patients undergoing pancreatectomy. BACKGROUND: The interplay between patient- and community-level factors on outcomes after complex surgery has not been well-examined. METHODS: Medicare beneficiaries who underwent a pancreatectomy between 2013 and 2017 were identified utilizing 100% Medicare inpatient files. P-SVI was determined using the Centers for Disease Control and Prevention criteria, whereas H-REI was estimated using Shannon Diversity Index. Impact of P-SVI and H-REI on "TO" [ie, no surgical complication/extended length-of-stay (LOS)/90-day mortality/90-day readmission] was assessed. RESULTS: Among 24,500 beneficiaries who underwent pancreatectomy, 12,890 (52.6%) were male and median age was 72 years (Interquartile range: 68-77); 10,619 (43.3%) patients achieved a TO. The most common adverse postoperative outcome was 90-day readmission (n = 8,066, 32.9%), whereas the least common was 90-day mortality (n = 2282, 9.3%). Complications and extended LOS occurred in 30.4% (n = 7450) and 23.3% (n = 5699) of the cohort, respectively. Patients from an above average SVI county who underwent surgery at a below average REI hospital had 18% lower odds [95% confidence interval (CI): 0.74-0.95] of achieving a TO compared with patients from a below average SVI county who underwent surgery at a hospital with above average REI. Of note, patients from the highest SVI areas who underwent pancreatectomy at hospitals with the lowest REI had 30% lower odds (95% CI: 0.54-0.91) of achieving a TO compared with patients from very low SVI areas who underwent surgery at a hospital with high REI. Further comparisons of these 2 patient groups indicated 76% increased odds of 90-day mortality (95% CI: 1.10-2.82) and 50% increased odds of an extended LOS (95% CI: 1.07-2.11). CONCLUSION: Patients with high social vulnerability who underwent pancreatectomy in hospitals located in communities with low racial/ethnic integration had the lowest chance to achieve an "optimal" TO. A focus on both patient- and community-level factors is needed to ensure optimal and equitable patient outcomes.

RESUMO

INTRODUCTION: Neoadjuvant therapy (NAT) is an emerging strategy for operable pancreatic ductal adenocarcinoma (PDAC). While NAT increases multimodal therapy completion, it risks functional decline and treatment dropout. We used decision analysis to determine optimal management of localized PDAC and consider risks faced by elderly patients. METHODS: A Markov cohort decision analysis model evaluated treatment options for a 60-year-old patient with resectable PDAC: (1) upfront pancreaticoduodenectomy or (2) NAT. One-way and probabilistic sensitivity analyses were performed. A subanalysis considered the scenario of a 75-year-old patient. RESULTS: For the base case, NAT offered an incremental survival gain of 4.6 months compared with SF (overall survival: 26.3 vs. 21.7 months). In one-way sensitivity analyses, findings were sensitive to recurrence-free survival for NAT patients undergoing adjuvant, probability of completing NAT, and probability of being resectable at exploration after NAT. On probabilistic analysis, NAT was favored in a majority of trials (97%) with a median survival benefit of 5.1 months. In altering the base case for the 75-year-old scenario, NAT had a survival benefit of 3.8 months. CONCLUSIONS: This analysis demonstrates a significant benefit to NAT in patients with localized PDAC. This benefit persists even in the elderly cohort.

RESUMO

BACKGROUND AND OBJECTIVES: Patients with locally advanced pancreatic cancer (LAPC) are increasingly treated with FOLFIRINOX, resulting in improved survival and resection of tumors that were initially unresectable. It remains unclear, however, which specific patients benefit from FOLFIRINOX. Two nomograms were developed predicting overall survival (OS) and resection at the start of FOLFIRINOX for LAPC. METHODS: From our multicenter, prospective LAPC registry in 14 Dutch hospitals, LAPC patients starting first-line FOLFIRINOX (April 2015-December 2017) were included. Stepwise backward selection according to the Akaike Information Criterion was used to identify independent baseline predictors for OS and resection. Two prognostic nomograms were generated. RESULTS: A total of 252 patients were included, with a median OS of 14 months. Thirty-two patients (13%) underwent resection, with a median OS of 23 months. Older age, female sex, Charlson Comorbidity Index ≤1, and CA 19.9 < 274 were independent factors predicting a better OS (c-index: 0.61). WHO ps >1, involvement of the superior mesenteric artery, celiac trunk, and superior mesenteric vein ≥ 270° were independent factors decreasing the probability of resection (c-index: 0.79). CONCLUSIONS: Two nomograms were developed to predict OS and resection in patients with LAPC before starting treatment with FOLFIRINOX. These nomograms could be beneficial in the shared decision-making process and counseling of these patients.

RESUMO

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) represents one of the most fatal malignancies worldwide. It is suggested that survival in PDAC depends, among other things, on pattern of disease recurrence. PATIENTS AND METHODS: We performed a pooled analysis of the adjuvant therapy studies CONKO-001, CONKO-005, and CONKO-006, including a total of 912 patients with regard to prognostic factors in patients with recurrent disease. Overall survival from disease recurrence (OS 2) and disease-free survival (DFS) from the day of surgery were expressed by Kaplan-Meier method and compared using log-rank testing and Cox regression. RESULTS: Of 912 patients treated within the previously mentioned CONKO trials, we identified 689 patients with disease recurrence and defined site of relapse. In multivariable analysis, the presence of isolated pulmonary metastasis, low tumour grading, and low postoperative level of CA 19-9 remained significant factors for improved OS 2 and DFS. Furthermore, completeness of adjuvant gemcitabine-based treatment (OS 2: P = 0.006), number of relapse sites (OS 2: P = 0.015), and type of palliative first-line treatment (OS 2: P < 0.001) significantly affected overall survival after disease recurrence in PDAC. CONCLUSIONS: Determining tumour subgroups using prognostic factors may be helpful to stratify PDAC patients for future clinical trials. In case of disease recurrence, the site of relapse may have a prognostic impact on subsequent survival. Further investigations are needed to identify differences in tumour biology, reflecting relapse patterns and the differing survival of PDAC patients.

RESUMO

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with poor prognosis. Radical surgery is the best option for cure and, nowadays, it is performed by many surgeons also in cases of vascular infiltration. Whether this aggressive approach to a locally advanced PDAC produces a survival benefit is under debate. Most data in the literature come from retrospective comparative studies; therefore, it is still unclear if such an extensive surgery for an advanced cancer is justified. METHODS: A retrospective review of patients with PDAC treated at our institution over a 12-year period was performed. Data concerning patients' characteristics, operative details, postoperative course, and long-term survival were retrieved from prospective databases and analysed. Factors associated with poor survival were assessed via Cox regression analysis. RESULTS: A total of 173 patients with PDAC were included in the analysis, 41 subjects underwent pancreatectomy with vascular resection for locally advanced disease, and in 132 patients, only a pancreatic resection was undertaken. Demographics, major comorbidities, and tumour characteristics were similar between the two groups. Length of surgery (P=0.0006), intraoperative blood transfusions (P<0.0001), and overall complications (P<0.0001) were significantly higher in the vascular resection group. Length of hospital stay (P=0.684) and 90-day mortality (P=0.575) were comparable between groups. Overall median survival (P= 0.717) and survival rates at 1, 3, and 5 years (P=0.964, P=0.500, and P=0.445, respectively) did not differ significantly between groups. Age ≥70 years and postoperative complications were independent predictors of lower survival. CONCLUSIONS: Our study confirms that pancreatectomy with vascular resection for a locally advanced PDAC is a complex operation associated with a significant longer operating time that may increase morbidity; however, in selected patients, R0 margins can be obtained with an acceptable long-term survival rate. Older patients are less likely to benefit from surgery.

RESUMO

BACKGROUND: The US News & World Report (USNWR) annual ranking of the best hospitals for gastroenterology and gastrointestinal surgery offers direction to patients and healthcare providers, especially for recommendations on complex medical and surgical gastrointestinal (GI) conditions. The objective of this study was to examine the outcomes of complex GI cancer resections performed at USNWR top-ranked, compared to non-ranked, hospitals. STUDY DESIGN: Using the Vizient database, data for patients who underwent esophagectomy, gastrectomy, and pancreatectomy for malignancy between January and December 2018 were reviewed. Perioperative outcomes were analyzed according to USNWR rank status. Primary outcome was in-hospital mortality. Secondary outcomes include length of stay, mortality index (observed-to-expected mortality ratio), rate of serious complication, and cost. Secondary analysis was performed for outcomes of patients who developed serious complications. RESULTS: There were 3,054 complex GI cancer resections performed at 42 top-ranked hospitals vs 3,608 resections performed at 198 non-ranked hospitals. The mean annual case volume was 73 cases at top-ranked hospitals compared to 18 cases at non-ranked hospitals. Compared with non-ranked hospitals, top-ranked hospitals had lower in-hospital mortality (0.96% vs 2.26%, respectively, p < 0.001) and lower mortality index (0.71 vs 1.53, respectively). There were no significant differences in length of stay, rate of serious complications, or direct cost between groups. In patients who developed serious morbidity, top-ranked hospitals had a lower mortality compared with non-ranked hospitals (8.2% vs 16.8%, respectively, p < 0.01). CONCLUSIONS: Within the context of complex GI cancer resection, USNWR top-ranked hospitals performed a 4-fold higher case volume and were associated with improved outcomes. Patients with complex GI-related malignancies may benefit from seeking surgical care at high-volume regional USNWR top-ranked hospitals.

RESUMO

BACKGROUND: Centralization of pancreatic surgery in the Netherlands has been ongoing since 2011. The aim of this study was to assess how centralization has affected the likelihood of resection and survival of patients with non-metastatic pancreatic head and periampullary cancer, diagnosed in hospitals with and without pancreatic surgery services. METHODS: An observational cohort study was performed on nationwide data from the Netherlands Cancer Registry (2009-2017), including patients diagnosed with non-metastatic pancreatic head or periampullary cancer. The period of diagnosis was divided into three time intervals: 2009-2011, 2012-2014 and 2015-2017. Hospital of diagnosis was classified as a pancreatic or non-pancreatic surgery centre. Analyses were performed using multivariable logistic and Cox regression models. RESULTS: In total, 10 079 patients were included, of whom 3114 (30.9 per cent) were diagnosed in pancreatic surgery centres. Between 2009-2011 and 2015-2017, the number of patients undergoing resection increased from 1267 of 3169 (40.0 per cent) to 1705 of 3566 (47.8 per cent) (P for trend < 0.001). In multivariable analysis, in 2015-2017, unlike the previous periods, patients diagnosed in pancreatic and non-pancreatic surgery centres had a similar likelihood of resection (odds ratio 1.08, 95 per cent c.i. 0.90 to 1.28; P = 0.422). In this period, however, overall survival was higher in patients diagnosed in pancreatic surgery than in those diagnosed in non-pancreatic surgery centres (hazard ratio 0.92, 95 per cent c.i. 0.85 to 0.99; P = 0.047). CONCLUSION: After centralization of pancreatic surgery, the resection rate for patients with pancreatic head and periampullary cancer diagnosed in non-pancreatic surgery centres increased and became similar to that in pancreatic surgery centres. Overall survival remained higher in patients diagnosed in pancreatic surgery centres.

RESUMO

BACKGROUND: The role of minimally invasive distal pancreatectomy is still unclear, and whether robotic distal pancreatectomy (RDP) offers benefits over laparoscopic distal pancreatectomy (LDP) is unknown because large multicentre studies are lacking. This study compared perioperative outcomes between RDP and LDP. METHODS: A multicentre international propensity score-matched study included patients who underwent RDP or LDP for any indication in 21 European centres from six countries that performed at least 15 distal pancreatectomies annually (January 2011 to June 2019). Propensity score matching was based on preoperative characteristics in a 1 : 1 ratio. The primary outcome was the major morbidity rate (Clavien-Dindo grade IIIa or above). RESULTS: A total of 1551 patients (407 RDP and 1144 LDP) were included in the study. Some 402 patients who had RDP were matched with 402 who underwent LDP. After matching, there was no difference between RDP and LDP groups in rates of major morbidity (14.2 versus 16.5 per cent respectively; P = 0.378), postoperative pancreatic fistula grade B/C (24.6 versus 26.5 per cent; P = 0.543) or 90-day mortality (0.5 versus 1.3 per cent; P = 0.268). RDP was associated with a longer duration of surgery than LDP (median 285 (i.q.r. 225-350) versus 240 (195-300) min respectively; P < 0.001), lower conversion rate (6.7 versus 15.2 per cent; P < 0.001), higher spleen preservation rate (81.4 versus 62.9 per cent; P = 0.001), longer hospital stay (median 8.5 (i.q.r. 7-12) versus 7 (6-10) days; P < 0.001) and lower readmission rate (11.0 versus 18.2 per cent; P = 0.004). CONCLUSION: The major morbidity rate was comparable between RDP and LDP. RDP was associated with improved rates of conversion, spleen preservation and readmission, to the detriment of longer duration of surgery and hospital stay.

RESUMO

BACKGROUND: The relationship between hospital volume and surgical outcomes is well-established; however, considerable socioeconomic and geographic barriers to high-volume care persist. This study assesses how the overall volume of hepatopancreaticobiliary (HPB) cancer operations impacts outcomes of liver resections (LRs). STUDY DESIGN: The National Cancer Database (2004-2014) was queried for patients who underwent LR for hepatocellular carcinoma. Hospital volume was determined separately for all HPB operations and LRs. Centers were dichotomized as low and high volume based on the median number of operations. The following study cohorts were created: low-volume hospitals (LVHs) for both LRs and HPB operations, mixed-volume hospitals (MVHs) with low-volume LRs but high-volume HPB operations, and high-volume LR hospitals (HVHs) for both LRs and HPB operations. RESULTS: Of 7,265 patients identified, 37.5%, 8.8%, and 53.7% were treated at LVHs, MVHs, and HVHs, respectively. On multivariable analysis, patients treated at LVHs had higher 30-day mortality compared with patients treated at HVHs (odds ratio 1.736; p < 0.001). However, patients treated at MVHs experienced 30-day mortality comparable with patients treated at HVHs (odds ratio 0.789; p = 0.318). Similar results were found for positive margin status, prolonged hospital stay, and overall survival. CONCLUSIONS: LR outcomes at low-volume LR centers that have substantial experience with HPB cancer operations are similar to those at high-volume LR centers. Our results demonstrate that the volume to outcomes curve for HPB operations should be assessed more holistically and that patients can safely undergo liver operations at low-volume LR centers if HPB volume criteria are met.

RESUMO

OBJECTIVES: To characterize clinical features of early onset pancreatic adenocarcinoma (EOPC) patients and explore prognostic factors affecting their survival. Methods: Retrospective review of 95 patients, 45 years old, who presented to the University of Alabama Hospitals with pancreatic adenocarcinoma from September 1998 to June 2018. Results: Median survival time was 12.9 months for all patients. Obesity, male gender, race, and tumor location were not associated with survival. Smoking at time of diagnosis increased risk of death by three folds (HR 3.05, 95% CI, 1.45 - 6.40). Risk of death decreased by 64% (HR 0.36, 95% CI, 0.16 - 0.78) if patients underwent surgery. Median survival was 119.5 months for stage I, 29.9 months for stage II, 23.23 months for stage III, and 6.3 months for stage IV patients. The survival benefit of chemotherapy was only significant with the use of FOLFIRINOX. Conclusions: Some established prognostic features in typical pancreatic adenocarcinoma patients are not predictive of survival in young patients. Cigarette smoking, a known risk factor for the development of EOPC, is also a significant predictor of survival in this patient population. Efforts to improve prognosis of EOPC include early detection, tobacco control, individualized treatment protocols, and studying the biological behavior.

RESUMO

BACKGROUND: Sixty million Americans live in rural America, with roughly 17.5% of the rural population being 65 y or older. Outcomes and costs of Medicare beneficiaries undergoing hepatopancreatic surgery at critical access hospitals (CAHs) are not known. MATERIALS AND METHODS: Medicare files were used to identify patients who underwent hepatopancreatic resection. Outcomes were compared (CAHs versus non-CAHs). RESULTS: Patients undergoing hepatopancreatic surgery at non-CAHs versus CAHs had a similar comorbidity score (4 versus 5, P = 0.53). After adjusting for patient-level factors and procedure-specific volume, there was no difference in complication rate (adjusted odds ratio (aOR) 0.80, 95% confidence interval (CI) 0.52-1.24). The median cost of hospitalization was roughly $4000 less at CAHs than that at non-CAHs (P < 0.001). However, compared with patients undergoing surgery at non-CAHs, beneficiaries operated at CAHs had more than two times the odds of dying within 30 (aOR 2.45, 95% CI 1.42-4.2) and 90 d (aOR 2.28, 95% CI 1.4-3.71). CONCLUSIONS: Only a small subset of Medicare beneficiaries underwent hepatic or pancreatic resection at a CAH. Despite similar complication rate, Medicare beneficiaries undergoing surgery at a CAH had more than two times the odds of dying within 30 and 90 d after surgery.

RESUMO

OBJECTIVE: There are limited data from retrospective studies on whether therapeutic outcomes after regular pancreatectomy are superior to those after enucleation in patients with small, peripheral and well-differentiated non-functional pancreatic neuroendocrine tumors. This study aimed to compare the short- and long-term outcomes of regular pancreatectomy and enucleation in patients with non-functional pancreatic neuroendocrine tumors. METHODS: Between January 2007 and July 2020, 227 patients with non-functional pancreatic neuroendocrine tumors who underwent either enucleation (n = 89) or regular pancreatectomy (n = 138) were included. Perioperative complications, disease-free survival, and overall survival probabilities were compared. Propensity score matching was performed to balance the baseline differences between the two groups. RESULTS: The median follow-up period was 60.76 months in the enucleation group and 43.29 months in the regular pancreatectomy group. In total, 34 paired patients were identified after propensity score matching. The average operative duration in the enucleation group was significantly shorter than that in the regular pancreatectomy group (147.94 ± 42.39 min versus 217.94 ± 74.60 min, P < 0.001), and the estimated blood loss was also significantly lesser (P < 0.001). The matched patients who underwent enucleation displayed a similar overall incidence of postoperative complications (P = 0.765), and a comparable length of hospital stay (11.12 ± 3.90 days versus 9.94 ± 2.62 days, P = 0.084) compared with those who underwent regular pancreatectomy. There were no statistically significant differences between the two groups in disease-free survival and overall survival after propensity score matching. CONCLUSION: Enucleation in patients with non-functional pancreatic neuroendocrine tumors was associated with shorter operative time, lesser intraoperative bleeding, similar overall morbidity of postoperative complications, and comparable 5-year disease-free survival and overall survival when compared with regular pancreatectomy.

RESUMO

OBJECTIVE: To determine the effect of a previously unassessed measure of quality-preventable hospitalization rate-on mortality after oncologic surgery for 4 procedures with established volume-outcome relationships. We hypothesize that hospitals with higher preventable hospitalization rates (indicating poor quality of primary care) have increased hospital mortality. Additionally, patients having surgery at hospitals with higher preventable hospitalization rates have increased mortality. SUMMARY BACKGROUND DATA: Although different factors have been used to measure healthcare quality, most have not resulted in long-term hospital-based improvements in patient outcomes. METHODS: We retrieved data from Taiwan's National Health Insurance database for patients who underwent surgery during 2001 to 2014 for esophagectomy, pancreatectomy, lung resection, or cystectomy. Preventable hospitalization rates assess hospitalizations for 11 chronic conditions that are deemed to be preventable with effective primary care. The outcome was 30-day surgical mortality. Identifiable factors potentially related to surgical mortality, including surgeon and hospital volume, were controlled for in the models. RESULTS: Our dataset contained 35,081 patients who had surgery for one of the procedures. For all procedures, hospitals with high preventable hospitalization rates were associated with higher mortality rates (all P < 0.01). For esophagectomy, lung resection, and cystectomy, the adjusted odds of individual mortality increased by 8% to 10% (P < 0.01) for every 1% increase in the preventable hospitalization rate. For pancreatectomy, the adjusted odds of individual mortality increased by 21% for every 1% increase in preventable hospitalization rate when the rate was ≥8% (P < 0.01). CONCLUSIONS: Preventable hospitalization rates could serve as warning signs of low quality of care and be a publically-reported quality measure.

RESUMO

BACKGROUND: There are limited data on the efficacy of neoadjuvant therapy (NAT) for early-stage distal pancreas adenocarcinoma (PDAC). Previous studies focused on adenocarcinoma of the head of the pancreas or dealt with borderline and locally advanced tumors of the body and tail. METHODS: This is a retrospective study of the National Cancer Database between 2006 and 2015. A propensity-matched analysis was performed to compare overall survival estimates between NAT and upfront resection (UR) groups. RESULTS: A total of 5003 distal pancreatectomies for PDAC were identified, of whom 408 (9%) received NAT. After 1:1 matching, 353 NAT patients were compared with 353 UR patients. NAT was associated with lower 90-day mortality. There were no differences in the number of lymph nodes retrieved, or length of stay. With matching, the NAT group had higher median overall survival compared with UR (33.0 vs. 27.0 months; p = 0.009) and adjusted overall survival (hazard ratio = 0.63, 95% confidence interval = 0.51-0.77; p < 0.001). CONCLUSION: The receipt of NAT followed by distal pancreatectomy for early-stage distal PDAC is associated with improved overall survival compared with UR. This study supports the use of NAT in the multimodal therapy paradigm of early-stage adenocarcinoma of the body and tail of the pancreas.

RESUMO

BACKGROUND: Cirrhosis has been considered a contraindication to major abdominal surgeries, due to increased risk for postoperative morbidity and mortality. The aim of this study was to assess the safety of pancreatectomy in cirrhotic versus non-cirrhotic patients. METHODS: The present systematic review and meta-analysis was performed according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. All meta-analyses were performed using the random effects model. RESULTS: Eight studies were eventually included, enrolling 1229 patients (cirrhotics: 722; and Child-Pugh A: 593; Child-Pugh B/C: 129) who underwent surgery for pancreatic cancer. The overall postoperative morbidity rate was 66% (51%-80%). Infections (26%) and ascites formation/worsening (23%) were the most common postoperative complications, followed by anastomotic leak/fistula (17%). Non-cirrhotic patients were less likely to suffer from anastomotic leak/fistula (OR: 0.39; 95% CI: 0.23-0.65) and infections (OR: 0.41; 95% CI: 0.25-0.67). Postoperative mortality rate was statistically significantly lower in non-cirrhotic versus cirrhotic patients (OR: 0.18; 95% CI:0.18-0.39). The odds ratios of 1 year (OR: 0.62; 95% CI: 0.30-1.30), 2 year (OR: 0.67; 95% CI: 0.25-1.83) and 3 year all-cause mortality (OR: 0.32; 95% CI: 20.03-2.99) were not significantly different between cirrhotic versus non-cirrhotic patients. CONCLUSION: This study demonstrated that non-cirrhotic patients were less likely to undergo any type of re-intervention and had statistically significant lower postoperative mortality rates compared to patients with cirrhosis.

RESUMO

Currently, there is no consensus on the optimal tumor response score (TRS) system to assess regression in pancreatic cancers resected after neoadjuvant therapy. We developed a novel TRS (Royal North Shore [RNS] system) based on estimating the percentage of tumor bed occupied by viable cancer and categorized into 3 tiers: grade 1 (≤10%), grade 2 (11% to 75%), and grade 3 (>75%). We assessed 147 resected carcinomas with this and other TRS systems (College of American Pathologists [CAP], MD Anderson Cancer Center [MDACC], and Evans). The 3-tiered RNS system predicted median survival after surgery for grades 1, 2, and 3 of 54, 23, and 9 months, respectively (P<0.05). The CAP, MDACC, and Evans systems also predicted survival (P<0.05) but less consistently. The median survival for MDACC and CAP grade 0 (complete regression) was less than MDACC grade 1 and CAP grades 1 and 2. There was no difference in survival between CAP grades 2 and 3 (P=0.960), Evans grades 1 and 2a (P=0.395), and Evans grades 2a and 2b (P=0.587). Interobserver concordance was weak for CAP (κ=0.431), moderate for MDACC (κ=0.691), minimal for Evans (κ=0.307), and moderate to strong for RNS (κ=0.632 to 0.84). Of age, sex, size, stage, grade, perineural and vascular invasion, extrapancreatic extension, margin status, and RNS score, only RNS score, vascular invasion, and extrapancreatic extension predicted survival in univariate analysis. Only extrapancreatic extension (P=0.034) and RNS score (P<0.0001) remained significant in multivariate analysis. We conclude that the RNS system is a reproducible and powerful predictor of survival after resection for pancreatic cancers treated with neoadjuvant therapy and should be investigated in larger cohorts.

RESUMO

INTRODUCTION: The objective of this study was to characterize time from cancer symptoms to diagnosis and time from diagnosis to surgical treatment among patients undergoing pancreatectomy for cancer. METHODS: Medicare beneficiaries who underwent pancreatectomy for cancer between 2013 and 2017 were identified using the 100% Medicare Inpatient Standard Analytic Files. Mixed effects negative binomial regression models were utilized to determine which factors were associated with the number of weeks to diagnosis and pancreatic resection. RESULTS: Among 7647 Medicare beneficiaries, two-thirds (n = 5127, 67%) had symptoms associated with a pancreatic cancer diagnosis before surgery. Median time from the first symptom to diagnosis was 6 weeks (IQR: 1-25) and the median time from diagnosis to surgery was 4 weeks (IQR: 2-15). In risk-adjusted models, female patients had 13% longer waiting times from identification of a related symptom to pancreatic cancer diagnosis (OR = 1.13, 95% CI: 1.05-1.21) and 12% longer waiting times from diagnosis to surgery (OR = 1.12, 95% CI: 1.07-1.18). Older age was associated with 10% longer waiting times from symptom identification to diagnosis (p < .0001). CONCLUSIONS: Female and older patients had longer wait times between symptom presentation and pancreatic cancer diagnosis. Sex-based disparities in cancer care need to be recognized and addressed by policymakers and health care institutions.

RESUMO

BACKGROUND: CONKO-006 was designed for patients with pancreatic adenocarcinoma with postsurgical R1 residual status to evaluate the efficacy and safety of the combination of gemcitabine and sorafenib (GemSorafenib) compared with those of gemcitabine + placebo (GemP) for 12 cycles. PATIENTS AND METHODS: This randomised, double-blind, placebo-controlled, multicenter study was planned to detect an improvement in recurrence-free survival (RFS) from 42% to 60% after 18 months. Secondary objectives were overall survival (OS), safety and duration of treatment. RESULTS: 122 patients were included between 02/2008 and 09/2013; 57 were randomised to GemSorafenib and 65 to GemP. Patient characteristics were wellbalanced (GemSorafenib/GemP) in terms of median age (63/63 years), tumour size (T3/T4: 97/97%), and nodal positivity (86/85%). Grade 3/4 toxicities comprised diarrhoea (GemSorafenib: 12%; GemP: 2%), elevated gamma-glutamyl transferase (GGT) (19%; 9%), fatigue (5%; 2%) and hypertension (5%; 2%), as well as neutropenia (18%; 25%) and thrombocytopenia (9%; 2%). By August 2017, 118 (97%) RFS event had occurred. There were no difference in RFS (median GemSorafenib: 8.5 versus GemP: 9.4 months; p = 0.730) nor OS (median GemSorafenib: 17.6 versus GemP: 17.5 months; p = 0.481). Landmark analyses suggest that patients who received more than six cycles of postoperative chemotherapy had significantly longer OS (p = 0.021). CONCLUSION: CONKO-006 is the first randomised clinical trial to include exclusively patients with PDAC with postsurgical R1 status thus far. Sorafenib added to gemcitabine did neither improve RFS nor OS. However, postoperative treatment exceeding six months seemed to prolong survival and should be further investigated in these high-risk patients.

RESUMO

INTRODUCTION: This study was undertaken to examine 100 consecutive robotic distal pancreatectomies with splenectomies, and to compare our outcomes to predicted outcomes as calculated using the American college of surgeons national surgical quality improvement program (ACS NSQIP) Surgical Risk Calculator and to the outcomes contained within NSQIP. METHODS: Outcomes were compared with predicted outcomes, calculated using the ACS NSQIP Surgical Risk Calculator, and with outcomes documented in NSQIP for distal pancreatectomy. For illustrative purposes, data are presented as median (mean ± SD). RESULTS: Patients who underwent robotic distal pancreatectomy were of age 67 (63 ± 13.4) years with a BMI of 29 (29 ± 6.3) kg/m2, with 49% being women. Operative duration was 242 (265 ± 112.2) minutes and estimated blood loss was 110 (211 ± 233.9) mL. Predicted outcomes were similar to those reported in NSQIP. Our actual outcomes were significantly superior to the predicted outcomes for serious complication, any complication, surgical site infection, sepsis, and length of stay. Compared to NSQIP outcomes, our actual outcomes for serious complication, any complication, surgical site infection, sepsis, and delayed gastric emptying were significantly superior. Twelve percent of operations were converted to "open." There were 3 deaths within 30 days, similar to predicted outcomes. Deaths were due to sepsis (2) and respiratory failure (1). CONCLUSION: Our patients' predicted outcomes were the same as national outcomes; our patients were not a select group. However, their actual outcomes were like or significantly superior than those predicted by NSQIP or reported in NSQIP. We believe that the robot has the future of distal pancreatectomy with or without splenectomy.

RESUMO

BACKGROUND: Observing cyclic patterns in surgical outcome is a common experience. We aimed to measure this phenomenon and to hypothesize possible causes using the experience of a high-volume pancreatic surgery department. METHODS: Outcomes of 2748 patients who underwent a Whipple procedure at a single high-volume center from January 2000 to December 2018 were retrospectively analyzed. Three different hypotheses were tested: the effect of climate changes, the "July effect" and the effect of vacations. RESULTS: Clavien-Dindo ≥ 3 morbidity was similar during warm vs. cold months (22.5% vs. 19.8%, p = 0.104) and at the beginning of activity of new trainees vs. the rest of the year (23.5 vs. 22.5%, p = 0.757). Patients operated when a high percentage of staff is on vacation showed an increased Clavien-Dindo ≥ 3 morbidity (22.3 vs. 18.5%, p = 0.022), but similar mortality (2.3 vs. 1.8%, p = 0.553). The surgical waiting list was also significantly longer during these periods (37 vs. 27 days, p = 0.037). Being operated in such a period of the year was an independent predictor of severe morbidity (OR 1.271, CI 95% 1.086-1.638, p = 0.031). CONCLUSION: Being operated when more staff is on vacation significantly affects severe morbidity rate. Future healthcare system policies should prevent the relative shortage of resources during these periods.
