ESMO Open 2024; 9:102241. [PMID: 38442453 PMCID: PMC10925937 DOI: 10.1016/j.esmoop.2024.102241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 11/19/2023] [Accepted: 01/09/2024] [Indexed: 03/07/2024] Open
Abstract
BACKGROUND Identifying the association between body mass index (BMI) or weight change and cancer prognosis is essential for the development of effective cancer treatments. We aimed to assess the strength and validity of the evidence of the association between BMI or weight change and cancer prognosis by a systematic evaluation and meta-analysis of relevant cohort studies. METHODS We systematically searched the PubMed, Web of Science, EconLit, Embase, Food Sciences and Technology Abstracts, PsycINFO, and Cochrane databases for literature published up to July 2023. Inclusion criteria were cohort studies with BMI or weight change as an exposure factor, cancer as a diagnostic outcome, and data type as an unadjusted hazard ratio (HR) or headcount ratio. Random- or fixed-effects models were used to calculate the pooled HR along with the 95% confidence interval (CI). RESULTS Seventy-three cohort studies were included in the meta-analysis. Compared with normal weight, overweight or obesity was a risk factor for overall survival (OS) in patients with breast cancer (HR 1.37, 95% CI 1.22-1.53; P < 0.0001), while obesity was a protective factor for OS in patients with gastrointestinal tumors (HR 0.67, 95% CI 0.56-0.80; P < 0.0001) and lung cancer (HR 0.67, 95% CI 0.48-0.92; P = 0.01) compared with patients without obesity. Compared with normal weight, underweight was a risk factor for OS in patients with breast cancer (HR 1.15, 95% CI 0.98-1.35; P = 0.08), gastrointestinal tumors (HR 1.54, 95% CI 1.32-1.80; P < 0.0001), and lung cancer (HR 1.28, 95% CI 1.22-1.35; P < 0.0001). Compared with nonweight change, weight loss was a risk factor for OS in patients with gastrointestinal cancer. CONCLUSIONS Based on the results of the meta-analysis, we concluded that BMI, weight change, and tumor prognosis were significantly correlated. These findings may provide a more reliable argument for the development of more effective oncology treatment protocols.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) impacts patients in their 60s, but its incidence in younger patients is increasing. We hypothesize that younger patients may have worse oncologic outcomes. METHODS Patients who underwent curative pancreatic resection for PDAC between January 2011 and December 2021 at a single institution were analyzed. Early-onset pancreatic cancer (EOPC) was defined as pancreatic cancer diagnosed in patients ≤50 years. Clinical and survival outcomes were compared between EOPC and Conventional Onset Pancreas Cancer (COPC). RESULTS A total of 1133 patients were identified, 65 (5.7%) were EOPC. Preoperative patient characteristics including sex, smoking status, alcohol habitus, diabetes mellitus, CA 19-9, and neoadjuvant therapy were similar between EOPC and COPC (p > 0.05). EOPC patients were more likely non-white (p = 0.03), had lower ASA scores (p = 0.02) and larger median tumor size (33 vs 28 mm, p = 0.04), but had similar pathological stages and rate of R0 resections (p > 0.05). Postoperative outcomes were similar (p > 0.05). There was no statistically significant difference in overall (HR 0.93, CI 0.64, 1.33; p = 0.68) or recurrence free (HR 1.05, CI 0.75, 1.48; p = 0.77) survival between the EOPC and COPC after adjusting for significant factors. CONCLUSION Patients with EOPC who underwent surgical resection had similar oncological outcomes compared to patients with COPC.

Abstract
BACKGROUND Circulating adiponectin and leptin have been associated with risk of pancreatic cancer. However, the relationship between long-term exposure to these adipokines in the prediagnostic period with patient survival has not been investigated. METHODS Adipokine levels were measured in prospectively collected samples from 472 patients with pancreatic cancer. Because of sex-specific differences in adipokine levels, associations were evaluated separately for men and women. In a subset of 415 patients, we genotyped 23 SNPs in adiponectin receptor genes (ADIPOR1 and ADIPOR2) and 30 SNPs in the leptin receptor gene (LEPR). RESULTS Adiponectin levels were inversely associated with survival in women [HR, 1.71; 95% confidence interval (CI), 1.15-2.54]; comparing top with bottom quartile but not in men (HR, 0.89; 95% CI, 0.46-1.70). The SNPs rs10753929 and rs1418445 in ADIPOR1 were associated with survival in the combined population (per minor allele HR, 0.66; 95% CI, 0.51-0.84, and HR, 1.33; 95% CI, 1.12-1.58, respectively). Among SNPs in LEPR, rs12025906, rs3790431, and rs17127601 were associated with survival in the combined population [HRs, 1.54 (95% CI, 1.25-1.90), 0.72 (95% CI, 0.59-0.88), and 0.70 (95% CI, 0.56-0.89), respectively], whereas rs11585329 was associated with survival in men only (HR, 0.39; 95% CI, 0.23-0.66; Pinteraction = 0.0002). CONCLUSIONS High levels of adiponectin in the prediagnostic period were associated with shorter survival among women, but not among men with pancreatic cancer. Several polymorphisms in ADIPOR1 and LEPR are associated with patient survival. IMPACT Our findings reveal the association between adipokine signaling and pancreatic cancer survival and demonstrate the importance of examining obesity-associated pathways in relation to pancreatic cancer in a sex-specific manner.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease characterized by dense stroma. Obesity is an important metabolic factor that greatly increases PDAC risk and mortality, worsens progression and leads to poor chemotherapeutic outcomes. With omics analysis, magnetic resonance and near-infrared fluorescence (MR/NIRF) dual-modality imaging and molecular functional verification, obesity as an important risk factor is proved to modulate the extracellular matrix (ECM) components and enhance Fibronectin (FN) infiltration in the PDAC stroma, that promotes tumor progression and worsens response to chemotherapy by reducing drug delivery. In the study, to visually evaluate FN in vivo and guide PDAC therapy, an FN-targeted nanoprobe, NP-CREKA, is synthesized by conjugating gadolinium chelates, NIR797 and fluorescein isothiocyanate to a polyamidoamine dendrimer functionalized with targeting peptides. A dual-modality strategy combining MR and NIRF imaging is applied, allowing effective visualization of FN in orthotopic PDAC with high spatial resolution, ideal sensitivity and excellent penetrability, especially in obese mice. In conclusion, the findings provide new insights into the potential of FN as an ideal target for therapeutic evaluation and improving treatment efficacy in PDAC, hopefully improving the specific management of PDAC in lean and obese hosts.

Abstract
BACKGROUND AND OBJECTIVE An association between body mass index (BMI) and pancreatic cancer is suggested in observational studies. However, further studies are required to substantiate available evidence. The aim of this study was to explore the association between BMI and pancreatic ductal adenocarcinoma (PDAC) risk, treatment, and mortality. METHODS A registry-based cohort study was performed by combining data from four registries in Norway. Baseline data were collected between 1963 and 1975 with follow-up data collected until 2018. Kaplan-Meier curves and multivariable Cox regressions were estimated. Chi-square tests were used to analyze differences between groups. RESULTS The study cohort consisted of 1,723,692 individuals. A total of 8973 PDAC cases were identified during 55,744,749 person-years of follow-up. A 5 kg/m2 increase in BMI was associated with an increased risk of PDAC if high BMI at young age (16-29 years) (hazard ratio (HR): 1.21, 95% confidence interval (CI): 1.13-1.31), both for men (HR: 1.30, 95% CI: 1.15-1.46) and women (HR: 1.16, 95% CI: 1.05-1.28). In men, there was a 52% increase in risk of early-onset PDAC (<age 50) (HR: 1.52, 95% CI: 1.13-2.03) with 5 kg/m2 increase in BMI. A total of 2645 individuals were diagnosed with stage 1-3 disease, of whom 1131 underwent curative surgery. In all, 49% of normal weight, 38% overweight, and 30% obese individuals with stage 1-3 PDAC underwent surgery with curative intent (p < 0.001). Cancer survival was lower in overweight and obese individuals for both sexes. Analysis adjusted for sex, age, and period of diagnosis confirmed increased risk of cancer death in obese individuals. CONCLUSION This study suggests that increased BMI in young adults may increase the risk of PDAC, and higher BMI in men is associated with an increased risk of early onset PDAC (<age 50). Overweight and obese individuals were less likely to undergo curative surgery and obese individuals had a higher risk of cancer-related death.

Abstract
Pancreatic cancer (PanCa) is a highly fatal malignancy with few modifiable risk and prognostic factors. This study investigates the association between cola, diet cola, and non-cola soft drink consumption and PanCa risk and mortality. A retrospective study was conducted using data from the Patient Epidemiology Data System (1982-1998) at Roswell Park Comprehensive Cancer Center (Buffalo, NY, USA), including 213 PanCa patients and 852 cancer-free controls. Data were collected using a self-administered questionnaire, including a 46-item food frequency questionnaire (FFQ). Multivariable logistic regression was used to estimate odds ratio (OR) and 95% confidence interval (CI) of cola, diet cola, and non-cola soft drink consumption and PanCa risk. Cox proportional hazard regression was used to estimate hazard ratios (HR) and 95% CIs of cola, diet cola, and non-cola soft drink consumption and PanCa mortality. Stratified analyses were conducted by sex, body mass index (BMI), and smoking status. We observed significant 55% increased odds of PanCa among patients consuming ≥1 regular cola per day (OR: 1.55, 95% CI: 1.01-2.39). We also observed non-significant 38% increased hazard of mortality among patients consuming ≥1 regular cola per day (HR: 1.38, 95% CI: 0.91-2.07). We conclude that regular cola consumption is a modifiable lifestyle that may be associated with PanCa risk and mortality following diagnosis.

Abstract
Obesity causes chronic inflammation and changes in gut microbiome. However, how this contributes to poor survival and therapy resistance in patients with pancreatic cancer remain undetermined. Our current study shows that high fat diet-fed obese pancreatic tumor bearing mice do not respond to standard of care therapy with gemcitabine and paclitaxel when compared to corresponding control diet-fed mice. C57BL6 mice were put on control and high fat diet for 1 month following with pancreatic tumors were implanted in both groups. Microbiome of lean (control) and obese (high fat diet fed) mice was analyzed. Fecal matter transplant from control mice to obese mice sensitized tumors to chemotherapy and demonstrated extensive cell death. Analysis of gut microbiome showed an enrichment of queuosine (Q) producing bacteria in obese mice and an enrichment of S-adenosyl methionine (SAM) producing bacteria in control diet-fed mice. Further, supplementation of obese animals with SAM sensitized pancreatic tumors to chemotherapy. Treatment of pancreatic cancer cells with Q increased PRDX1 involved in oxidative stress protection. In parallel, tumors in obese mice showed increase in CD133+ treatment refractory tumor populations compared to control animals. These observations indicated that microbial metabolite Q accumulation in high fat diet-fed mice protected tumors from chemotherapy induced oxidative stress by upregulating PRDX1. This protection could be reversed by treatment with SAM. We conclude that relative concentration of SAM and queuosine in fecal samples of pancreatic cancer patients can be developed as a potential biomarker and therapeutic target in chemotherapy refractory pancreatic cancer.

Abstract
BACKGROUND The association between body mass index (BMI) and the overall survival (OS) of pancreatic ductal adenocarcinoma (PDAC) patients remains controversial and unclear, METHOD: A total of 2010 patients from a high-volume center were enrolled in the study. The OS of PDAC patients was evaluated based on restricted cubic spline (RCS), propensity score (PS) and multivariable risk adjustment analyses. RESULT BMI was linearly related to the OS (total P = 0.004, nonlinear P = 0.124). BMI was analyzed as categorical data based on X-tile software-defined cutoffs and World Health Organization (WHO)-recommended cutoffs. Adjusted with confounding covariates, higher BMI manifested as a positive prognostic predictor. Furthermore, BMI was proven to be associated with the OS in the PS analysis. (UnderweightXtile vs. NormalXtileP = 0.003, OverweightXtile vs. NormalXtileP = 0.019; UnderweightWHO vs. NormalWHOP < 0.001, OverweightWHO vs. NormalWHOP = 0.024). It was also revealed that patients with higher BMI benefitted more from chemotherapy. (Adjusted hazard ratio (aHR): UnderweightXtile vs. NormalXtile vs. OverweightXtile: 0.565 vs. 0.474 vs. 0.409; UnderweightWHO vs. NormalWHO vs. OverweightWHO: 0.613 vs. 0.464 vs. 0.425). CONCLUSION Among PDAC patients, there was a positive association between BMI and the OS, especially in patients treated with chemotherapy.

Impact of diabetes and modifiable risk factors on pancreatic cancer survival in a population-based study after adjusting for clinical factors. Cancer Causes Control 2021; 33:37-48. [PMID: 34633573 DOI: 10.1007/s10552-021-01497-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Accepted: 09/22/2021] [Indexed: 01/18/2023]
Abstract
PURPOSES Our study aimed to examine the impact of diabetes, smoking and BMI on pancreatic cancer survival in a population-based setting by adjusting both sociodemographic and clinical factors and measuring their attributable risk. METHODS Data on pancreatic adenocarcinoma patients diagnosed in 2011-2017 were acquired from the Louisiana Tumor Registry. Diabetes, smoking, height, and weight were abstracted from medical records and linked with Hospital Inpatient Discharge Data to enhance the completeness of the diabetes data. The Cox regression model was used to assess effect sizes of diabetes, smoking, and BMI on cancer-specific survival and survival rate. The partial population attributable risk was employed to measure the attributable risk of these risk factors. RESULTS Of the 3,200 eligible patients, 34.6% were diabetics, 23.9% were current smokers, and 52.3% had BMI ≥ 25 kg/m2. After adjusting for sociodemographic and clinical factors, diabetic patients had an increased cancer-specific death risk of 15% (95% CI, 1.06-1.25), 36% (95% CI, 1.19-1.44) for current smokers, and 24% (95% CI, 1.00-1.54) for patients with a BMI ≥ 40 when compared to their counterparts. Diabetic current smokers had significantly lower 2- and 3-year adjusted cancer-specific survival rates, 13.1% and 10.5%, respectively. By eliminating diabetes and modifiable risk factors, an estimated 16.6% (95% CI, 6.9%-25.9%) of the cancer-specific deaths could be avoided during a nine-year observational period between 2011 and 2019. CONCLUSIONS Diabetes and smoking contributed substantially to the reduction of pancreatic cancer survival even after controlling for sociodemographic and clinical factors; however, BMI ≥ 35 was observed to increase risk of mortality among stage III-IV patients only.

Abstract
Physical frailty and nutritional malassimilation are often observed after pancreaticoduodenectomy for pancreatic cancer. But long-term data concerning the course of micronutrient status is still missing. Micronutrient status after pylorus preserving pancreaticoduodenectomy with a follow-up of 12 months was evaluated using data of a randomized controlled trial. 47 patients were randomized with respect to the physiotherapy regimen they received (intensified physiotherapy: n = 22; standard physiotherapy: n = 25). Nutritional status was recorded preoperatively and postoperatively after one week, 3, 6 and 12 months. BMI, body fat measurement and albumin, lipid, iron and bone metabolism parameters, vitamins A, B1 B6 and B12, homocysteine, folic acid, and trace elements were measured. Laboratory values were analyzed descriptively. Differences between the groups were analyzed using the t-test in SPSS. For vitamin D, B1, B6 and iron a deficiency over time could be demonstrated with 50% of all patients or more being below normal range. The other laboratory values were in low normal range after 3 months and later. Significant differences between groups were found in cholesterol, HDL and selenium levels (corrected p-values < 0.033 in all cases). Vitamin D and iron should be supplemented postoperatively in the long term, and vitamin B1 and B6 substitution should be considered in symptomatic patients. Levels of malnutrition induced fatigue should be comparable between both groups. However, the role of nutritional status on other health-related aspects such as quality of life should be the focus of further studies.Trial Registration Number in the German Registry for Clinical Studies: DRKS00006786; Date of Registration: 01.10.2014.

Abstract
BACKGROUND Emerging evidence indicates associations between high-fat diet (HFD), metabolic syndrome (MetS), and increased risk of pancreatic cancer. However, individual components of an HFD that increase cancer risk have not been isolated. In addition, a specific pattern of cytokine elevation by which MetS drives pancreatic tumor progression is not well described. We hypothesized that oleic acid (OA), a major component of HFD, would augment pancreatic neoplastic processes. METHODS An orthotopic pancreatic cancer model with Panc02 cells was used to compare the effect of low-fat diet to OA-based HFD on cancer progression. Tumors were quantitated, analyzed by immunohistochemistry. In addition, serum cytokine levels were quantitated. Proliferation, migration assays, and expression of epithelial-to-mesenchymal transition factors were evaluated on Panc02 and MiaPaCa-2 pancreatic cancer cells cultured in high concentrations of OA. RESULTS HFD tumor-bearing mice (n = 8) had an 18% weight increase (P < 0.001) and increased tumor burden (P < 0.05) compared with the low-fat diet tumor-bearing group (n = 6). HFD tumors had significantly increased angiogenesis (P < 0.001) and decreased apoptosis (P < 0.05). Serum of HFD mice demonstrated increased levels of glucagon and glucagon-like peptide-1. Two pancreatic cancer cell lines cultured in OA demonstrated significant increases in proliferation (P < 0.001) and a >2.5-fold increase in cell migration (P < 0.001) when treated with OA. Panc02 treated with OA had increased expression of epithelial-to-mesenchymal transition factors SNAI-1 (Snail) and Zeb-1(P < 0.01). CONCLUSIONS High-fat conditions in vitro and in vivo resulted in an aggressive pancreatic cancer phenotype. Our data support further investigations elucidating molecular pathways augmented by MetS conditions to identify novel therapeutic strategies for pancreatic cancer.

Abstract
Genetic risk variants that have been identified in genome-wide association studies of complex diseases are primarily non-coding1. Translating these risk variants into mechanistic insights requires detailed maps of gene regulation in disease-relevant cell types2. Here we combined two approaches: a genome-wide association study of type 1 diabetes (T1D) using 520,580 samples, and the identification of candidate cis-regulatory elements (cCREs) in pancreas and peripheral blood mononuclear cells using single-nucleus assay for transposase-accessible chromatin with sequencing (snATAC-seq) of 131,554 nuclei. Risk variants for T1D were enriched in cCREs that were active in T cells and other cell types, including acinar and ductal cells of the exocrine pancreas. Risk variants at multiple T1D signals overlapped with exocrine-specific cCREs that were linked to genes with exocrine-specific expression. At the CFTR locus, the T1D risk variant rs7795896 mapped to a ductal-specific cCRE that regulated CFTR; the risk allele reduced transcription factor binding, enhancer activity and CFTR expression in ductal cells. These findings support a role for the exocrine pancreas in the pathogenesis of T1D and highlight the power of large-scale genome-wide association studies and single-cell epigenomics for understanding the cellular origins of complex disease.

Abstract
Backgrounds/Aims Diabetes mellitus (DM) is a known risk factor for morbidity, length of hospital stay, or mortality after surgery, however, its impact on postoperative course and long-term survival after pancreaticoduodenectomy (PD) is not clear. Methods This is a retrospective analysis of prospectively maintained database of 141 patients with periampullary and pancreatic head adenocarcinoma operated between January 2001 and March 2019. Clinico-pathological records and follow-up data were retrieved and analyzed. Cumulative hazard was computed for comparing the survival between DM and non-DM. Results DM was present in 31/141 (21.9%) patients, while 16/31 (51.6%). were new-onset DM (NODM). Tumor size, lymphovascular & perineural invasion, type of surgery, lymph node positivity and R0 resection rate were comparable between diabetic and non-diabetic. There was no significant difference in postoperative pancreatic fistula, delayed gastric emptying, infectious complication, hospital stay and mortality between DM and nondiabetics. Patients with DM had worse survival at 3 years (OS: HR, 3.11 [1.43-6.76] p=0.004, DFS: HR, 2.61 [1.23-5.53] p=0.01) and 5 years (OS: HR, 3.32 [1.46-7.53] p=0.004, DFS: HR, 2.87 [1.29-6.41] p=0.009). On multivariate analysis, DM (3 year OS: HR, 2.61 [1.14-5.98] p=0.022, DFS: HR, 2.19; p=0.058) (5 year OS: HR, 2.55; p=0.04, DFS: HR, 2.25; p=0.068) and pylorus resecting surgery were significantly associated with worse survival at 3 and 5 years. Conclusions Preoperative DM has no significant effect on postoperative course but has negative impact on 3-year and 5-year OS and DFS after PD for pancreatic and periampullary adenocarcinoma.

Obesity and Pancreatic Cancer: A Matched-Pair Survival Analysis. J Clin Med 2020; 9:jcm9113526.

Abstract
BACKGROUND Morbid obesity is a risk factor for pancreatic ductal adenocarcinoma (PDAC). However, the impact of obesity on postoperative outcomes and overall survival in patients with PDAC remains a controversial topic. METHODS Patients who underwent pancreatic surgery for PDAC between 1997 and 2018 were included in this study. Matched pairs (1:1) were generated according to age, gender and American Society of Anesthesiologists status. Obesity was defined according to the WHO definition as BMI ≥ 30 kg/m2. The primary endpoint was the difference in overall survival between patients with and without obesity. RESULTS Out of 553 patients, a total of 76 fully matched pairs were generated. Obese patients had a mean BMI-level of 33 compared to 25 kg/m2 in patients without obesity (p = 0.001). The frequency of arterial hypertension (p = 0.002), intraoperative blood loss (p = 0.039), and perineural invasion (p = 0.033) were also higher in obese patients. Clinically relevant postoperative complications (p = 0.163) and overall survival rates (p = 0.885) were comparable in both study groups. Grade II and III obesity resulted in an impaired overall survival, although this was not statistically significant. Subgroup survival analyses revealed no significant differences for completion of adjuvant chemotherapy and curative-intent surgery. CONCLUSIONS Obesity did not affect overall survival and postoperative complications in these patients with PDAC. Therefore, pancreatic surgery should not be withheld from obese patients.

Abstract
PURPOSE Diabetes mellitus (DM) has been proposed to be tumorigenic; however, prior studies of the association between DM and survival are conflicting. The goal of this ancillary analysis of RTOG 9704, a randomized controlled trial of adjuvant chemotherapy in pancreatic cancer, was to determine the prognostic effects of DM and insulin use on survival. METHODS AND MATERIALS Eligible patients from RTOG 9704 with available data on DM and insulin use were included. Overall survival (OS) and disease-free survival (DFS) were estimated using the Kaplan-Meier method, and variable levels were compared using log-rank test. Cox proportional hazards models were created to assess the associations among DM, insulin use, and body mass index phenotypes on outcomes. RESULTS Of 538 patients enrolled from 1998 to 2002, 238 patients were eligible with analyzable DM and insulin use data. Overall 34% of patients had DM and 66% did not. Of patients with DM, 64% had insulin-dependent DM, and 36% had non-insulin-dependent DM. On univariable analysis, neither DM nor insulin dependence were associated with OS or DFS (P > .05 for all). On multivariable analysis, neither DM, insulin use, nor body mass index were independently associated with OS or DFS. Nonwhite race (hazard ratio [HR], 2.18; 95% confidence interval [CI], 1.35-3.50; P = .0014), nodal involvement (HR, 1.74; 95% CI, 1.24-2.45; P = .0015), and carbohydrate antigen 19-9 (CA19-9) ≥90 U/mL (HR, 3.61; 95% CI, 2.32-5.63; P < .001) were associated with decreased OS. Nonwhite race (HR, 1.67; 95% CI, 1.05-2.63; P = .029) and CA19-9 ≥90 U/mL (HR, 2.86; 95% CI, 1.85-4.40; P < .001) were associated with decreased DFS. CONCLUSIONS DM and insulin use were not associated with OS or DFS in patients with pancreatic cancer in this study. Race, nodal involvement, and increased CA19-9 were significant predictors of outcomes. These data might apply to the more modern use of neoadjuvant therapies for potentially resectable pancreatic cancer.

Abstract
Pancreatic adenocarcinoma (PDAC) is associated with poor clinical outcomes and incomplete responses to conventional therapy. Therefore, there is an unmet clinical need to better understand the predisposing factors for pancreatic cancer in hopes of providing early screening to high-risk patients. While select risk factors such as age, race, and family history, or predisposing syndromes are unavoidable, there are several new and established risk factors that allow for intervention, namely by counseling patients to make the appropriate lifestyle modifications. Here, we discuss the best-studied risk factors for PDAC such as tobacco use and chronic pancreatitis, as well as newly emerging risk factors including select nutritional deficits, bacterial infections, and psychosocial factors. As several of these risk factors appear to be additive or synergistic, by understanding their relationships and offering coordinated, multidisciplinary care to high-risk patients, it may be possible to reduce pancreatic cancer incidence and improve clinical outcomes through early detection.

Langenbecks Arch Surg 2020; 405:313-324. [PMID: 32367394 DOI: 10.1007/s00423-020-01874-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Accepted: 03/29/2020] [Indexed: 12/14/2022]
Abstract
PURPOSE Some clinical studies have suggested that metformin improved prognoses in several cancers. This study aimed to identify prognostic factors for pancreatic ductal adenocarcinoma (PDAC) and determine the utility of metformin administration. METHODS Between January 2007 and December 2015, 373 consecutive patients underwent curative surgery for PDAC. Among the patients, 121 were diagnosed as having diabetes mellitus (DM) before surgery. The characteristics and overall survival (OS) between patients with and without DM were compared retrospectively. Based on their metformin intake, patients with DM were divided into two groups. OS rates between patients with and without metformin intake were compared. Univariate and multivariate analyses were performed to identify prognostic factors for OS among all patients and those with PDAC and DM. RESULTS No significant differences in the 5-year survival rates between patients with and without DM were observed. Among the 121 patients with DM, 18 received metformin and 103 did not (other medications group). The 5-year survival rate was significantly better in the metformin group than in the other medications group (66.7% and 24.4%, respectively; p = 0.034). Multivariate analysis identified pN1 (p = 0.002), metformin administration (p = 0.022), and microvascular invasion (p = 0.023) as independent prognostic factors for OS in the patients with DM. Matched-pair analysis showed that OS tended to be better in the metformin group than in the other medications group (p = 0.067). CONCLUSIONS History of metformin intake may contribute to favorable prognosis in patients with PDAC and pre-existing DM.

Increased Adiposity Enhances the Accumulation of MDSCs in the Tumor Microenvironment and Adipose Tissue of Pancreatic Tumor-Bearing Mice and in Immune Organs of Tumor-Free Hosts. Nutrients 2019; 11:nu11123012. [PMID: 31835454 PMCID: PMC6950402 DOI: 10.3390/nu11123012] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Revised: 11/25/2019] [Accepted: 11/26/2019] [Indexed: 12/11/2022] Open
Abstract
Obesity is associated with increased risk and reduced survival for many types of cancer. Increasing adiposity may affect the balance between immunosuppressive and antitumor mechanisms critical for dictating cancer progression or remission. The goal of the current study was to determine if increased adiposity altered tumor growth, survival, and myeloid-derived suppressor cell (MDSC) accumulation in a subcutaneous murine model of pancreatic cancer. C57BL/6 mice were placed on a 30% kcal calorie-restricted diet, 10% kcal from fat diet fed ad libitum, or 60% kcal from fat diet fed ad libitum for 16 weeks to generate lean, overweight, and obese mice, respectively; followed by subcutaneous injection with 1 × 106 Panc.02 cells. We observed a significant linear relationship between increased adiposity and increased tumor growth and mortality; increased accumulation of Gr-1+CD11b+ MDSCs; and reduced CD8 T cell:MDSC ratio in multiple tissues, including tumor. Increased adiposity also increased the accumulation of MDSCs in the spleen and lymph node of tumor-free mice. These data suggest adiposity induces MDSC accumulation, which may contribute to an immunosuppressive environment promoting tumor growth. Overall, our findings provide a rationale to prevent or reverse increased body weight as a strategy to reduce the accumulation of immunosuppressive cell types.

Abstract
OBJECTIVES Squamous cell carcinoma (SCC) of pancreas is rare entity with poorly defined prognostic factors and therapeutic outcomes. We sought to determine the overall survival (OS) and prognostic factors of patients with pancreatic SCC using National Cancer Database (NCDB) (2004-15). METHODS Kaplan-Meier method and log-rank test were used to perform OS analysis. Propensity-matched analysis was used to compare the OS of pancreatic SCC and adenocarcinoma. RESULTS Of the 515 cases included in our analysis, 46% were female. Approximately half of the cohort (48%) received chemotherapy or radiation therapy or both. Twenty six percent (33/125) of stage I and II disease (localized disease), 11% (8/72) of stage III, and 2% (6/318) of stage IV disease underwent surgical resection of the primary tumor. Median OS for the entire cohort was 4 months and was significantly higher in patients who underwent surgical resection of the primary tumor (17 vs 4 months, p < 0.001). In localized disease, adjuvant chemotherapy was not associated with improved OS in early stage disease (20 vs 24 months, p = 0.60). Stage IV patients treated with chemotherapy had a better OS than those without (5 vs 2 months, p < 0.0001). Propensity matched analysis demonstrated no significant differences in median OS between pancreatic adenocarcinoma (4.8 months) and SCC (4 months, p = 0.09). CONCLUSIONS Pancreatic SCC had a diverse OS that varied significantly according to increasing age (>70 years) and stage of the disease at presentation (p < 0.01). Surgical resection of primary tumor was associated with longer OS in stages I-II, whereas chemotherapy was associated with longer OS in stage IV disease.

Abstract
Among all the deadly cancers, pancreatic cancer ranks seventh in mortality. The absence of any grave symptoms coupled with the unavailability of early prognostic and diagnostic markers make the disease incurable in most of the cases. This leads to a late diagnosis, where the disease would have aggravated and thus, incurable. Only around 20% of the cases present the early disease diagnosis. Surgical resection is the prime option available for curative local disease but in the case of advanced cancer, chemotherapy is the standard treatment modality although the patients end up with drug resistance and severe side effects. Desmoplasia plays a very important role in chemoresistance associated with pancreatic cancer and consists of a thick scar tissue around the tumor comprised of different cell populations. The interplay between this heterogenous population in the tumor microenvironment results in sustained tumor growth and metastasis. Accumulating evidences expose the crucial role played by the tumor-associated macrophages in pancreatic cancer and this review briefly presents the origin from their parent lineage and the importance in maintaining tumor hallmarks. Finally we have tried to address their role in imparting chemoresistance and the therapeutic interventions leading to reduced tumor burden.

Abstract
Cystic fibrosis is a genetic disease affecting more than 70,000 people worldwide. Caused by a mutation in the CFTR gene, cystic fibrosis can result in difficulty breathing, widespread bacterial infections, edema, malnutrition, pancreatitis, and death. Current drug-based treatments struggle to reach the site of action due to the thick mucus, and only manage symptoms such as blocked airways, lung infections, and limited ability to digest food. Nanotechnology opens up possibilities for improved treatment strategies by focusing on drug penetration through the mucus lining, eliminating resulting bacterial infections, and targeting the underlying genetic cause of the disease. In this review, we present recent nanoparticle developments for cystic fibrosis, challenges in nanomedicine therapeutics, and future research directions in gene editing and nonviral vectors for gene delivery.

Abstract
Obesity is a growing medical and public health problem worldwide. Many digestive diseases are related to obesity. In this article, the current state of our knowledge of obesity-related digestive diseases, their pathogenesis, and the medical and metabolic consequences of weight reduction are discussed. Obesity-related digestive diseases include gastroesophageal reflux disease, Barrett’s esophagus, esophageal cancer, colon polyp and cancer, nonalcoholic fatty liver disease, hepatitis C-related disease, hepatocellular carcinoma, gallstone, cholangiocarcinoma, and pancreatic cancer. Although obesity-related esophageal diseases are associated with altered mechanical and humoral factors, other obesity-related digestive diseases seem to be associated with obesity-induced altered circulating levels of adipocytokines and insulin resistance. The relationship between functional gastrointestinal disease and obesity has been debated. This review provides a comprehensive evaluation of the obesity-related digestive diseases, including pathophysiology, obesity-related risk, and medical and metabolic effects of weight reduction in obese subjects.

Abstract
Pancreatic cancer is difficult to diagnose in an early stage, and has the highest mortality of all types of cancer. Obesity, high body mass index, and increased abdominal girth are established risk factors. Some studies have postulated that there is a correlation between organ steatosis and pancreatic cancer. This study aims to explore whether nonalcoholic fatty liver disease (NAFLD) is a risk factor and a prognostic factor for pancreatic cancer. The study enrolled 557 patients (143 with and 414 without pancreatic cancer) who were diagnosed between January 2009 and December 2013. We reviewed the abdominal computed tomographic scans of the patients to confirm the diagnosis of NAFLD. Clinical parameters, laboratory data, and personal information were analyzed. NAFLD is an independent risk factor for pancreatic cancer according to adjusted multivariate logistic regression analysis (OR 2.63, 95% CI 1.24-5.58, p = 0.011). The Kaplan-Meier survival curve reveals that patients without NAFLD have longer survival than patients with NAFLD (p = 0.005, log-rank test). NAFLD is positively correlated with pancreatic cancer, a result suggesting that NAFLD may increase the incidence and risk of pancreatic cancer. Patients with pancreatic cancer and NAFLD have poorer overall survival than patients without NAFLD, perhaps, because dysregulated cytokine status leads to progression of pancreatic cancer. NAFLD may be a prognostic factor for pancreatic cancer.

Abstract
Background Although advanced pancreatic ductal adenocarcinoma (PDAC) is characterized by progressive weight loss and nutritional deterioration, the effect of cancer cachexia and body mass index (BMI) at diagnosis on survival remains unclear. Methods We retrospectively evaluated a prospectively collected internal cancer registry of PDAC cases from 2006-2014 at the Kaiser Permanente Medical Center. Cancer cachexia was defined as weight loss greater than 5% over the 6 months prior to diagnosis. Multivariate cox proportional hazards regression was used to assess the influence of cachexia on survival. To evaluate effect measure modification of this relationship, we performed additional analyses stratified by race, BMI class, stage, receipt of surgery and receipt of chemotherapy. We tested for heterogeneity by fitting models with an interaction term for cachexia and the modifying variable. Results Of the 977 patients, 611 (63%) were identified with cachexia. Cachexia in PDAC patients was prevalent across all stages of disease and BMI classes. Patients with cachexia had lower survival (median 4.3 months, IQR 1.7-10.0) compared to those without cachexia (median 5.2 months, IQR 2.0-10.6), log-rank P=0.03. In this analysis BMI at diagnosis was not associated with survival. In the multivariate Cox regression, cachexia was independently associated with decreased overall survival (HR 1.24, CI: 1.06-1.45, P=0.01). However, the effect of cachexia on survival outcomes was modified by receipt of chemotherapy. Cachectic patients who did not receive chemotherapy had a 40% increase in risk of death compared to non-cachectic patients (HR 1.40, CI: 1.12-1.75), while those receiving chemotherapy were unaffected by cachexia (HR 1.04, CI: 0.82-1.32, Pinteraction=0.01). Conclusions In the largest cohort of pancreatic cancer patients examined to date, cachexia and not obesity is independently associated with worse survival in PDA and its effect is negated by systemic chemotherapy.

Abstract
AIM To evaluate the association of body mass index (BMI) with the overall survival of pancreatic ductal adenocarcinoma (PDAC) patients.
METHODS A retrospective analysis of PDAC patients diagnosed in the National Cancer Center of China between January 1999 and December 2014 was performed. These patients were categorized into four BMI groups (< 18.5, 18.5-22.9, 23-27.4 and ≥ 27.5 kg/m2). χ2 tests for comparison of the proportions of categorical variables, and Student’s t-test or Mann-Whitney test for continuous variables were employed. Survival analysis was performed with the Kaplan-Meyer method. Their HRs of mortality and 95%CIs were estimated using the Cox proportional hazards model.
RESULTS With a median age of 59.6 years (range: 22.5-84.6 years), in total 1783 PDAC patients were enrolled in this study. Their mean usual BMI was 24.19 ± 3.53 for the whole cohort. More than half of the patients (59.3%) experienced weight loss during the disease onset and progression. Compared with healthy-weight individuals, newly diagnosed patients who were overweight or obese had more severe weight loss during their disease onset and progression (P < 0.001). Individuals who were overweight or obese were associated with positive smoking history (P < 0.001). A significant difference in comorbidity of diabetes (P = 0.044) and coronary artery disease (P < 0.001) was identified between high BMI and normal-weight patients. After a median follow-up of 8 mo, the survival analysis showed no association between BMI and the overall survival (P = 0.90, n = 1783). When we stratified the whole cohort by pancreatic cancer stage, no statistically significant association between BMI and overall survival was found for resectable (P = 0.99, n = 217), unresectable locally advanced (P = 0.90, n = 316) and metastatic patients (P = 0.88, n = 1250), respectively. The results did not change when we used the BMI at diagnosis.
CONCLUSION Our results showed no significance of BMI for the overall survival of PDAC patients.

Effects of alcohol drinking and smoking on pancreatic ductal adenocarcinoma mortality: A retrospective cohort study consisting of 1783 patients. Sci Rep 2017; 7:9572. [PMID: 28851896 PMCID: PMC5574975 DOI: 10.1038/s41598-017-08794-1] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2017] [Accepted: 07/19/2017] [Indexed: 01/18/2023] Open
Abstract
The effects of alcohol drinking and smoking on pancreatic ductal adenocarcinoma (PDAC) mortality are contradictory. Individuals who were diagnosed as PDAC and hospitalized at the China National Cancer Center between January 1999 and January 2016 were identified and included in the study. Ultimately, 1783 consecutive patients were included in the study. Patients were categorized as never, ex-drinkers/smokers or current drinkers/smokers. Hazard ratios (HRs) of all-cause mortality and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models. Compared with never drinkers, the HRs were 1.25 for ever drinkers, 1.24 for current drinkers, and 1.33 for ex-drinkers (trend P = 0.031). Heavy drinking and smoking period of 30 or more years were positive prognostic factors for PDAC. For different smoking and alcohol drinking status, only subjects who are both current smokers and current drinkers (HR, 1.45; 95% CI, 1.03–2.05) were associated with reduced survival after PDAC compared to those who were never smokers and never drinkers. Patients who are alcohol drinkers and long-term smokers before diagnosis have a significantly higher risk of PDAC mortality. Compared to those who neither smoker nor drink, only patients who both smokers and drinkers were associated with reduced survival from PDAC.

Positive Effect of Higher Adult Body Mass Index on Overall Survival of Digestive System Cancers Except Pancreatic Cancer: A Systematic Review and Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2017; 2017:1049602. [PMID: 28948163 PMCID: PMC5602622 DOI: 10.1155/2017/1049602] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/24/2017] [Revised: 05/27/2017] [Accepted: 05/31/2017] [Indexed: 02/08/2023]
Abstract
High body mass index (BMI) has been inconsistently associated with overall survival (OS) of digestive system cancers (DSCs). This meta-analysis was conducted to investigate whether high BMI was associated with DSCs prognosis. 34 studies were accepted, with a total of 23,946 DSC cases. Hazard ratios (HRs) with 95% confidence intervals (95% CIs) for OS in BMI categories from individual studies were extracted and pooled by random-effect model. The overall HR of DSCs except pancreatic cancer for OS of adult overweight cases was 0.76 (95% CI = 0.67–0.85). DSC individuals except pancreatic cancer with adult obesity were at decreased risk for OS (HR = 0.85, 95% CI = 0.72–0.98). Among DSC patients except pancreatic cancer, the overall HR for the highest versus the lowest BMI category was 0.82 (95% CI = 0.71–0.92). Additionally, comparing the highest and lowest BMI categories, the combined HR of pancreatic cancer was 1.22 (95% CI = 1.01–1.43). Our meta-analysis suggested an increased OS among adult overweight and obese DSC survivors except pancreatic cancer. Overweight and obesity in adulthood may be important prognostic factors that indicate an increased survival from DSC patients except pancreatic cancer.

Abstract
Pancreatic cancer has few known risk factors, providing little in the way of prevention, and is the most rapidly fatal cancer with 7 % survival rate at 5 years. Obesity has surfaced as an important risk factor for pancreatic cancer as epidemiological studies with strong methodological designs have removed important biases and solidified the obesity associations. Moreover, studies indicate that obesity early in adulthood is strongly associated with future risk of pancreatic cancer and that abdominal obesity is an independent risk factor. There is increasing evidence suggesting long-standing diabetes type 2 and insulin resistance are important etiological factors of this disease, providing a strong mechanistic link to obesity. The challenge remains to determine whether intended weight loss in midlife will reduce risk of pancreatic cancer and to elucidate the complex underlying pathways directly involved with risk.

Abstract
BACKGROUND Pancreatic cancer is a rapidly fatal disease with gemcitabine remaining the first-line therapy. We performed a genotype-phenotype association study to identify biomarkers for predicting gemcitabine treatment outcome. MATERIALS AND METHODS We selected the top 200 single nucleotide polymorphisms (SNPs) identified from our previous genome-wide association study to associate with overall survival using 400 patients treated with/or without gemcitabine, followed by imputation analysis for regions around the identified SNPs and a replication study using an additional 537 patients by the TaqMan genotyping assay. Functional validation was performed using quantitative reverse transcription-PCR for gemcitabine-induced expression in genotyped lymphoblastoid cell lines and siRNA knockdown for candidate genes in pancreatic cancer cell lines. RESULTS Four SNPs in chromosome 1, 3, 9, and 20 showed an interaction with gemcitabine from the discovery cohort of 400 patients (P<0.01). Subsequently, we selected those four genotyped plus four imputed SNPs for SNP×gemcitabine interaction analysis using the secondary validation cohort. Two imputed SNPs in CDH4 and KRT8P35 showed a trend in interaction with gemcitabine treatment. The lymphoblastoid cell lines with the variant sequences showed increased CDH4 expression compared with the wild-type cells after gemcitabine exposure. Knockdown of CDH4 significantly desensitized pancreatic cancer cells to gemcitabine cytotoxicity. The CDH4 SNPs that interacted with treatment are more predictive than prognostic. CONCLUSION We identified SNPs with gemcitabine-dependent effects on overall survival. CDH4 might contribute to variations in gemcitabine response. These results might help us to better predict gemcitabine response in pancreatic cancer.

Abstract
The prevalence of overweight (body mass index [BMI], 25 to 29.9 kg/m2) and obesity (BMI ≥ 30 kg/m2) have increased dramatically in the United States. Because increasing BMI is associated with the development of multiple different cancer types, including most GI cancers, providers will frequently encounter patients with GI cancer who are overweight or obese. Mounting evidence associates overweight and/or obesity with worsened prognosis in multiple GI cancers, including esophageal, gastric, hepatocellular, pancreatic, and colorectal. However, these data are observational and may be subject to bias and/or confounding. Furthermore, in some cancer types, the associations between BMI and outcomes is not linear, where overweight and class I obese patients may have an improvement in outcome. This report provides a brief highlight of existing studies that have linked overweight and/or obesity to prognosis in GI cancer; provides recommendations on best management practices; and discusses limitations, controversies, and future directions in this rapidly evolving area. There are multiple areas of promise that warrant continued investigation: What are the comparative contributions of energy balance, including weight, dietary patterns, and physical activity on cancer prognosis? What are the specific physiologic pathways that mediate the relationship between energy balance and prognosis? What is the relationship between low muscle mass (sarcopenia) or sarcopenic obesity and cancer prognosis? Are there subsets of patients for whom purposefully altering energy balance would be deleterious to prognosis? This area is rich with opportunities to understand how states of energy (im)balance can be favorably altered to promote healthy survivorship.

Abstract
AIM To investigate the effect of diabetes mellitus (DM) on disease-free and overall post-resection survival of patients with pancreatic ductal adenocarcinoma (PDAC). METHODS Prospective observational study on patients admitted for pancreatic disease from January 2008 to October 2012. DM was classified as recent-onset (<48 months before PDAC diagnosis), longstanding (≥48 months before PDAC) or new onset (after surgery). RESULTS Of 296 patients, 140 had a diagnosis of DM prior to surgery (26 longstanding, 99 recent-onset, 15 with unknown duration). Median follow-up time was 5.4 ± 0.22 years. Patients with recent onset DM had poorer postoperative survival than patients without DM: disease-free survival and overall survival were 1.14±0.13 years and 1.52±0.12 years in recent onset DM, versus 1.3±0.15 years and 1.87±0.15 years in non-diabetic patients (p = 0.013 and p = 0.025, respectively). Longstanding DM and postoperative new onset DM had no impact on prognosis. Compared to cases without DM, patients with recent onset DM were more likely to have residual disease after surgery and to develop liver metastases during follow-up. Multivariate analysis confirmed recent onset DM was independently associated with PDAC relapse (hazard ratio 1.45 [1.06-1.99]). CONCLUSION Preoperative recent onset DM has an impact on survival after the resection of PDAC.

Abstract
UNLABELLED It remains unclear how obesity worsens treatment outcomes in patients with pancreatic ductal adenocarcinoma (PDAC). In normal pancreas, obesity promotes inflammation and fibrosis. We found in mouse models of PDAC that obesity also promotes desmoplasia associated with accelerated tumor growth and impaired delivery/efficacy of chemotherapeutics through reduced perfusion. Genetic and pharmacologic inhibition of angiotensin-II type-1 receptor reverses obesity-augmented desmoplasia and tumor growth and improves response to chemotherapy. Augmented activation of pancreatic stellate cells (PSC) in obesity is induced by tumor-associated neutrophils (TAN) recruited by adipocyte-secreted IL1β. PSCs further secrete IL1β, and inactivation of PSCs reduces IL1β expression and TAN recruitment. Furthermore, depletion of TANs, IL1β inhibition, or inactivation of PSCs prevents obesity-accelerated tumor growth. In patients with pancreatic cancer, we confirmed that obesity is associated with increased desmoplasia and reduced response to chemotherapy. We conclude that cross-talk between adipocytes, TANs, and PSCs exacerbates desmoplasia and promotes tumor progression in obesity. SIGNIFICANCE Considering the current obesity pandemic, unraveling the mechanisms underlying obesity-induced cancer progression is an urgent need. We found that the aggravation of desmoplasia is a key mechanism of obesity-promoted PDAC progression. Importantly, we discovered that clinically available antifibrotic/inflammatory agents can improve the treatment response of PDAC in obese hosts.

Abstract
MARCH2 (membrane-associated RING-CH protein 2), an E3 ubiquitin ligase, is mainly associated with the vesicle trafficking. In the present study, for the first time, we demonstrated that MARCH2 negatively regulates autophagy. Our data indicated that overexpression of MARCH2 impaired autophagy, as evidenced by attenuated levels of LC3B-II and impaired degradation of endogenous and exogenous autophagic substrates. By contrast, loss of MARCH2 expression had the opposite effects. In vivo experiments demonstrate that MARCH2 knockout mediated autophagy results in an inhibition of tumorigenicity. Further investigation revealed that the induction of autophagy by MARCH2 deficiency was mediated through the PIK3CA-AKT-MTOR signaling pathway. Additionally, we found that MARCH2 interacts with CFTR (cystic fibrosis transmembrane conductance regulator), promotes the ubiquitination and degradation of CFTR, and inhibits CFTR-mediated autophagy in tumor cells. The functional PDZ domain of MARCH2 is required for the association with CFTR. Thus, our study identified a novel negative regulator of autophagy and suggested that the physical and functional connection between the MARCH2 and CFTR in different conditions will be elucidated in the further experiments.

Abstract
Although obesity has been identified as a risk factor for pancreatic cancer, the important question of whether obesity influences the prognosis of pancreatic cancer has not been explicated thoroughly. We therefore performed a meta-analysis to investigate the association between body mass index (BMI) and survival outcomes of patients with pancreatic cancer.Studies that described the relationship between BMI and overall survival (OS) of pancreatic cancer were searched in PubMed, Embase, Ovid, and Cochrane Library Databases from the earliest available date to May 12, 2015. Hazard ratios (HRs) for OS in each BMI category from individual studies were extracted and pooled by a random-effect model. Dose-response meta-analysis was also performed to estimate summary HR and 95% confidence interval (CI) for every 5-unit increment. Publication bias was evaluated by Begg funnel plot and Egger linear regression test.Ten relevant studies involving 6801 patients were finally included in the meta-analysis. Results showed that obesity in adulthood significantly shortened OS of pancreatic cancer patients (HR: 1.29, 95% CI: 1.17-1.41), whereas obesity at diagnosis was not associated with any increased risk of death (HR: 1.10, 95% CI: 0.78-1.42). For every 5-kg/m increment in adult BMI, the summary HR was 1.11 (95% CI: 1.05-1.18) for death risk of pancreatic cancer. However, no dose-response relationship was found in the BMI at diagnosis. Egger regression test and Begg funnel plot both revealed no obvious risk of publication bias.In conclusion, increased adult BMI is associated with increased risk of death for pancreatic cancer patients, which suggested that obesity in adulthood may be an important prognostic factor that indicates an abbreviated survival from pancreatic cancer. More studies are needed to validate this finding, and the mechanism behind the observation should be evaluated in further studies.

Abstract
BACKGROUND Diabetes mellitus (DM) is a risk factor for pancreatic cancer (PC), but its prognostic value in PC is still unclear. To elucidate this issue, we systematically reviewed the evidence concerning the association between diabetes status and PC. METHODS Medline and EMBASE databases were searched to identify the eligible studies. Overall and subgroup analyses were performed to detect the discrepancy of prognosis according to diabetes status. Hazard ratios (HRs) with 95% CI were used to estimate the effect size. RESULTS Eighteen studies including 16,181 patients with sample size ranging from 113 to 4,658 were pooled in this meta-analysis. Results showed that patients with DM had worse survival (HR 1.19, 95% CI: 1.07-1.32). In view of the impact of diabetes duration and tumor stage on the outcomes, we classified the studies into different groups. The results indicated that DM was associated with survival in both long-standing diabetes (HR 1.26, 95% CI: 1.14-1.40) and recent-onset diabetes (HR 1.29, 95% CI: 1.09-1.51). Data regarding localized disease (HR 1.57, 95% CI: 1.00-2.46) and nonlocalized (locally advanced and metastatic) disease (HR 1.42, 95% CI: 1.16-1.73) verified that the prognostic value was independent of tumor stage. CONCLUSION Our results suggested that patients with DM were associated with worse survival than those without DM. Diabetes may be a predictive factor of survival in patients with PC. Surveillance of diabetes status and antidiabetes medication administration after the diagnosis of PC is of clinical importance.

Premorbid Obesity and Mortality in Patients With Pancreatic Cancer: A Systematic Review and Meta-analysis. Clin Gastroenterol Hepatol 2016; 14:355-368.e; quiz e32. [PMID: 26460214 PMCID: PMC4919073 DOI: 10.1016/j.cgh.2015.09.036] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2015] [Revised: 09/22/2015] [Accepted: 09/30/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Obesity is associated with an increased risk for pancreatic cancer, but it is unclear whether it affects mortality. We performed a systematic review and meta-analysis to assess the association between premorbid obesity and mortality from pancreatic cancer. METHODS We performed a systematic search through January 2015 and identified studies of the association between premorbid obesity (at least 1 year prior to pancreatic cancer diagnosis) and pancreatic cancer-related mortality. We estimated summary adjusted hazard ratio (aHR) with 95% confidence interval (CI), comparing data from obese (body mass index [BMI] ≥30 kg/m(2)) and overweight subjects (BMI, 25.0-29.9 kg/m(2)) with those from individuals with a normal BMI (controls) by using random-effects model. RESULTS We identified 13 studies (including 3 studies that pooled multiple cohorts); 5 studies included only patients with pancreatic cancer, whereas 8 studies evaluated pancreatic cancer-related mortality in cancer-free individuals at inception. In the meta-analysis, we observed increase in pancreatic cancer-related mortality among overweight (aHR, 1.06; 95% CI, 1.02-1.11; I(2) = 0) and obese individuals (aHR, 1.31; 95% CI, 1.20-1.42; I(2) = 43%), compared with controls; the association remained when we analyzed data from only subjects with pancreatic cancer. Each 1 kg/m(2) increase in BMI was associated with 10% increase in mortality (aHR, 1.10; 95% CI, 1.05-1.15) with minimal heterogeneity (I(2) = 0). In the subgroup analysis, obesity was associated with increased mortality in Western populations (11 studies; aHR, 1.32; 95% CI, 1.22-1.42) but not in Asia-Pacific populations (2 studies; aHR, 0.98; 95% CI, 0.76-1.27). CONCLUSIONS In a systematic review and meta-analysis, we associated increasing level of obesity with increased mortality in patients with pancreatic cancer in Western but not Asia-Pacific populations. Strategies to reduce obesity-induced metabolic abnormalities might be developed to treat patients with pancreatic cancer.

Abstract
PURPOSE Obesity promotes pancreatic and breast cancer progression via mechanisms that are poorly understood. Although obesity is associated with increased systemic levels of placental growth factor (PlGF), the role of PlGF in obesity-induced tumor progression is not known. PlGF and its receptor VEGFR-1 have been shown to modulate tumor angiogenesis and promote tumor-associated macrophage (TAM) recruitment and activity. Here, we hypothesized that increased activity of PlGF/VEGFR-1 signaling mediates obesity-induced tumor progression by augmenting tumor angiogenesis and TAM recruitment/activity. EXPERIMENTAL DESIGN We established diet-induced obese mouse models of wild-type C57BL/6, VEGFR-1 tyrosine kinase (TK)-null, or PlGF-null mice, and evaluated the role of PlGF/VEGFR-1 signaling in pancreatic and breast cancer mouse models and in human samples. RESULTS We found that obesity increased TAM infiltration, tumor growth, and metastasis in pancreatic cancers, without affecting vessel density. Ablation of VEGFR-1 signaling prevented obesity-induced tumor progression and shifted the tumor immune environment toward an antitumor phenotype. Similar findings were observed in a breast cancer model. Obesity was associated with increased systemic PlGF, but not VEGF-A or VEGF-B, in pancreatic and breast cancer patients and in various mouse models of these cancers. Ablation of PlGF phenocopied the effects of VEGFR-1-TK deletion on tumors in obese mice. PlGF/VEGFR-1-TK deletion prevented weight gain in mice fed a high-fat diet, but exacerbated hyperinsulinemia. Addition of metformin not only normalized insulin levels but also enhanced antitumor immunity. CONCLUSIONS Targeting PlGF/VEGFR-1 signaling reprograms the tumor immune microenvironment and inhibits obesity-induced acceleration of tumor progression.

Abstract
BACKGROUND The aim of the study is to investigate differences in clinical presentation, disease stage and survival of operable pancreatic cancer patients with new onset DM compared to long standing diabetes mellitus (DM) and non diabetics. METHODS A prospectively maintained pancreatic cancer surgery database of a tertiary care teaching hospital from January 2006 to August 2012 was reviewed. Only patients with a histological diagnosis of pancreatic carcinoma (PC) were included in final analysis. DM was defined as HbA1c >6.5% or any patient on anti-diabetic treatment regardless of HbA1c value. New onset DM was defined when diagnosed within two preceding years of surgery. Patients were stratified into two groups: DM and non DM. Among the DM patients, patients with new onset DM were further stratified and studied separately. Staging of PC was performed according to the 6(th) edition of AJCC. Survival of patients with PC was determined by reviewing medical records. Patients and their families were contacted if there was no existing follow-up. RESULTS Eighty-six patients (n=55, 63.9% male) with a mean age of 62 years (range, 29-85 years) underwent pancreatic cancer surgery during the study period. Of the 86 patients, 30 (34%) had DM of which eight patients (9% overall) had new onset DM. DM patients tended to be older compared to non DM patients (67.8 vs. 58.5 years, P=0.0005). The majority of non DM patients were symptomatic (98.2%), and there was a tendency for DM group patients to be asymptomatic at presentation (13.3% vs. 1.8%, P=0.05). Abdominal pain was less common in DM patients compared to non DM patients (30% vs. 53.6%, P=0.04). The median duration of new onset DM prior to diagnosis of PC was 2 months (range, 1-23 months). There was a tendency for DM patients to present at an early stage (stage I and stage II) (P=0.08). There was no difference in survival (P=0.17) for new onset DM compared to long standing DM and non DM patients. CONCLUSIONS DM patients tend to be older and are less likely to present with abdominal pain. Asymptomatic presentation and early stage disease tends to occur in DM patients. A larger sample size is required to determine if survival of new onset DM patients differs from long standing and non DM patients.

Abstract
Concurrent diabetes has been linked with an increased risk of death in many cancers, but findings in pancreatic cancer have been inconsistent. We performed a systematic review and meta-analysis to assess the effect of diabetes on survival in patients with pancreatic cancer. Of 4, 463 original articles, 41 were included in the review; 29 studies with 33 risk estimates were included in the meta-analysis. In the overall comparison of patients with pancreatic cancer and diabetes with their nondiabetic counterparts, the former had significantly higher all-cause mortality (pooled HR: 1.13; 95% CI: 1.04-1.22). Subgroup analyses showed that diabetes was associated with poor survival in patients with resectable disease (HR: 1.37; 95% CI: 1.15-1.63) but not in those with unresectable disease (HR: 1.07; 95% CI: 0.89-1.29). The HR (95% CI) was 1.52 (1.20-1.93) for patients with new-onset diabetes (≤ 2 years of diabetes duration) and 1.22 (0.83-1.80) for those with longstanding diabetes (> 2 years). Diabetes was associated with higher mortality overall in patients with pancreatic cancer. The effect of diabetes on overall survival was associated with the stages of tumor and the duration of diabetes.

Abstract
Patients with pancreatic cancer have a high frequency of concurrent diabetes. This study is aimed to demonstrate the impact of diabetes on clinical outcome of pancreatic cancer. Clinical and epidemiological information was collected from medical records or by personal interview in 1328 patients with pancreatic ductal adenocarcinoma. Diabetes was defined by a known medical history, or abnormal fasting blood glucose (FBG) and HbA1c levels within three months of the cancer diagnosis. Duration of ≤3 years was used as the cutoff to arbitrarily define the new-onset and long-term diabetes. Logistic regression, Kaplan-Meier plot, log-rank test and Cox regression models were employed in the data analysis. Elevated level of FBG or HbA1c was observed in 24.7% and 11.5% of the patients without a known diabetes history, respectively. The prevalence of DM was 44.4% and was comparable by strata of tumor stage. New-onset diabetes was a significant independent predictor for risk of death in metastatic patients (HR=1.35, 95% CI=1.11-1.63, P=0.002) and in all patients (HR=1.23, 95% CI=1.09-1.40, P=0.001). Both new-onset and long term diabetes were significantly associated with older age, obesity, hypertension and coronary artery disease as well as weight loss. New-onset diabetes was also significantly related to larger tumors and elevated level of CA19-9 but not to tumor site and presence of biliary obstruction. Diabetes in general and new-onset diabetes in particular, is associated with poor outcome of pancreatic cancer. New-onset and long-term diabetes share common risk factors for type 2 diabetes.

Abstract
BACKGROUND Although high body mass index (BMI) increases risk for developing esophageal adenocarcinoma (EAC), the prognostic influence of BMI is unknown in esophageal squamous carcinoma. METHODS BMI was calculated using measured height and weight at the first diagnosis and categorized as overweight (25 to 29.9 kg/m(2)), normal (18.5 to 24.9 kg/m(2)) or underweight (<18.5 kg/m(2)). Survival was compared by using the log-rank test on the Kaplan-Meier life table. Multivariate Cox regression analysis was used to evaluate whether BMI was an independent prognostic factor for disease-specific survival (DSS). RESULTS Among 1,176 esophageal squamous carcinoma patients, 146 (12.4%) were categorized as overweight, and 277 (23.6%) underweight. More patients in the underweight group had anemia (P=0.001), weight loss (P=0.035) and R1 resection (P<0.001). Less patients in the underweight group received adjuvant chemotherapy (P=0.01). Patients in the overweight group had a higher incidence rate of high blood pressure (P<0.001), diabetes (P<0.001) and coronary artery diseases (P<0.001). Moreover, more patients in the overweight group had a lower TNM stage (P=0.003). In the univariated analysis, high BMI was significantly associated with better DSS (P=0.013). CONCLUSIONS After adjusting for covariates enrolled for study, high BMI was an independent prognostic factor in weight loss esophageal squamous carcinoma patients.

Abstract
The worldwide obesity epidemic is paralleled by a rise in the incidence of pancreatic disorders ranging from "fatty" pancreas to pancreatitis and cancer. Body fat accumulation and pancreatic dysfunctions have common pathways, mainly acting through insulin resistance and low-grade inflammation, frequently mediated by the epigenome. These mechanisms are affected by lifestyle and by the toxic effects of fat and pollutants. An early origin is common, starting in pediatric age or during the fetal life in response to nutritional factors, endocrine disruptor chemicals (EDCs) or parental exposure to toxics. A "fatty pancreas" is frequent in obese and is able to induce pancreatic damage. The fat is a target of EDCs and of the cytotoxic/mutagenic effects of heavy metals, and is the site of bioaccumulation of lipophilic and persistent pollutants related with insulin resistance and able to promote pancreatic cancer. Increased Body Mass Index (BMI) can act as independent risk factor for a more severe course of acute pancreatitis and obesity is also a well-known risk factor for pancreatic cancer, that is related with BMI, insulin resistance, and duration of exposure to the toxic effects of fat and/or of environmental pollutants. All these mechanisms involve gene-environment interactions through epigenetic factors, and might be manipulated by primary prevention measures. Further studies are needed, pointing to better assess the interplays of modifiable factors on both obesity and pancreatic diseases, and to verify the efficacy of primary prevention strategies involving lifestyle and environmental exposure to toxics.

Abstract
BACKGROUND Obesity is a risk factor for developing pancreatic cancer. We investigated the impact of obesity on survival in patients diagnosed with locally advanced or metastatic pancreatic cancer. METHODS In a multicentre, retrospective study, we included all patients with advanced or metastatic pancreatic cancer treated at four Swiss hospitals between 1994 and 2004. We categorized patients into four body mass index (BMI) groups (<18.5, 18.5 - 25, ≥ 25 - 29, ≥30 kg/m2) and used multivariable Cox regression to investigate the impact of BMI on survival. Missing data were handled using multiple imputations. RESULTS 483 patients were included. Median age was 66 years (range 59-74), 47% were female, 82% had stage IV disease, 72% had an ECOG below 2, and 84% were treated with gemcitabine-based first-line chemotherapy. After a median follow-up of 8.5 months, 6 and 12-month survival probabilities of the whole cohort were 67% (95% CI 63% - 71%) and 37% (95% CI 33% - 42%), respectively. Unadjusted 12-month survival rates in each BMI group were: 48% (95% CI 33% - 62%), 42% (95% CI 36% - 48%), 30% (95% CI 22% - 38%), and 11% (95% CI 4% - 24%), respectively. In multivariable analysis, increasing BMI (HR 1.22, 95% CI 1.04 - 1.41, p = 0.012) and CA 19-9 (HR 1.07, 95% CI 1.02 - 1.11, p = 0.003) were significantly associated with worse survival prognosis. Patients with a good clinical performance status (ECOG < 2) had a better prognosis (HR 0.76, 95% CI 0.65 - 0.96, p = 0.019). CONCLUSIONS Obese patients diagnosed with advanced pancreatic cancers have a worse prognosis compared to non-obese patients. BMI should be considered for risk stratification in future clinical trials.

Impact of diabetes mellitus on clinical outcomes in patients undergoing surgical resection for pancreatic cancer: a retrospective, cohort study. Am J Gastroenterol 2014; 109:1484-92. [PMID: 25070053 PMCID: PMC4477801 DOI: 10.1038/ajg.2014.193] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2013] [Accepted: 05/28/2014] [Indexed: 02/06/2023]
Abstract
OBJECTIVES Diabetes mellitus (DM) has a bidirectional association with pancreatic cancer (PaC); however, its effect on clinical outcomes has not been thoroughly evaluated. We analyzed these data in a large sample of PaC subjects who had undergone surgical resection. METHODS Subjects enrolled in the Mayo Clinic Pancreatic Cancer SPORE registry from 2000 to 2010 who had resection with curative intent were identified (n=488). Tumor size, cancer stage, and postoperative median survival were evaluated. Median survivals were compared with Kaplan-Meier curves and Cox proportional hazards regression modeling. RESULTS A total of 275 (56%) subjects had DM before surgery. DM subjects had larger tumors compared with those without DM (3.6 cm vs. 3.3, P=0.002), even after controlling for covariates including age, body mass index, and tumor grade. Cancer stage at the time of surgery was not affected by DM status (P=0.575). Preoperative DM was not associated with an increased risk of death using a multivariable survival analysis (hazard ratio 1.06, 95% confidence interval 0.81-1.38, P=0.676). The median survival following cancer resection was similar between subjects with and without DM (24 vs. 26 months, P=0.610). In addition, postoperative survival was similar on the basis of the duration of DM (new-onset vs. long-standing) and prior use of antidiabetic treatments in diabetic subjects. CONCLUSIONS PaC subjects with DM have larger tumors than nondiabetic subjects. Despite this observation, preoperative DM does not negatively impact the cancer stage at the time of surgery or postoperative survival. Thus, the effect of DM on tumor size is either overshadowed by early metastatic spread of the cancer or is mitigated by the tumor resection.

J Pain Symptom Manage 2014; 48:13-25. [PMID: 24321510 DOI: 10.1016/j.jpainsymman.2013.08.017] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2013] [Revised: 08/07/2013] [Accepted: 08/13/2013] [Indexed: 01/03/2023]
Abstract
CONTEXT High body mass index (BMI) is linked to an increased risk of developing pancreatic cancer (PC). However, in patients with advanced PC (APC), especially those receiving palliative chemotherapy, the impact of BMI on survival has not been investigated fully. OBJECTIVES To assess changes in BMI during the course of APC and their impact on patient survival, specifically for those receiving palliative chemotherapy. METHODS Consecutive patients with APC, all of whom were treated with palliative chemotherapy, were enrolled during 2003-2010. Clinical characteristics and prognoses were analyzed. RESULTS A total of 425 patients participated (median age, 60.1 years). At diagnosis of APC, patients' BMI distribution of patients was as follow: <18.5 (45, 10.6%); 18.5-19.9 (67, 15.8%); 20.0-22.4 (156, 36.7%); 22.5-24.9 (107, 25.2%); 25.0-29.9 (49, 11.5%); and ≥ 30.0 (1, 0.2%). Median overall survival (OS) was 8.1 months (95% confidence interval 7.2, 9.1). Precancer BMI and baseline BMI (at diagnosis) had no impact on OS. Weight loss at diagnosis (precancer weight minus weight at diagnosis) and weight loss during first-line chemotherapy (both stipulated as BMI change ≥ 1) were associated with shortened OS (hazard ratio, 1.300; P = 0.012 and hazard ratio, 1.367; P = 0.010, respectively). CONCLUSION In patients with APC undergoing palliative chemotherapy, decreases in BMI at APC diagnosis and during chemotherapy are more hazardous for OS than precancer BMI or baseline BMI (at diagnosis) as absolute values. Further studies are needed to validate this finding and investigate strategies to maintain BMI during chemotherapy in this setting.

Diabetes and pancreatic cancer survival: a prospective cohort-based study. Br J Cancer 2014; 111:181-5. [PMID: 24786605 PMCID: PMC4090724 DOI: 10.1038/bjc.2014.224] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2014] [Revised: 04/01/2014] [Accepted: 04/04/2014] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Diabetes is a risk factor for pancreatic cancer but its association with survival from pancreatic cancer is poorly understood. Our objective was to investigate the association of diabetes with survival among pancreatic cancer patients in a prospective cohort-based study where diabetes history was ascertained before pancreatic cancer diagnosis. METHODS We evaluated survival by baseline (1993-2001) self-reported diabetes history (n=62) among 504 participants that developed exocrine pancreatic cancer within the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial. Hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality were estimated using Cox proportional hazards model, adjusted for age, sex, body mass index, race, smoking, and tumour stage (local, locally advanced, and metastatic). RESULTS The multivariable-adjusted HR for mortality comparing participants with diabetes to those without was 1.52 (95% CI=1.14-2.04, P-value <0.01). After excluding those diagnosed with pancreatic cancer within 3 years of study enrolment, HR for mortality among those with diabetes was 1.45 (95% CI=1.06-2.00, P-value=0.02). CONCLUSIONS Using prospectively collected data, our findings indicate that diabetes is associated with worse survival among patients with pancreatic cancer.

Constitutive activation of nuclear factor κB contributes to cystic fibrosis transmembrane conductance regulator expression and promotes human cervical cancer progression and poor prognosis. Int J Gynecol Cancer 2014; 23:906-15. [PMID: 23640294 DOI: 10.1097/igc.0b013e318292da82] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/17/2022] Open
Abstract
OBJECTIVE Cystic fibrosis transmembrane conductance regulator (CFTR) and nuclear factor κB (NF-κB) have been known to play important roles in the development and progression of many types of cancer including cervical cancer. The study aimed to verify the relevance and significance of CFTR and NF-κB expressions in cervical cancer tissues and cell lines. METHODS The expressions of CFTR and NF-κB p65 were analyzed respectively by immunohistochemistry in total of 135 cervical tissue samples. The correlation to clinicopathologic characteristics and prognostic value was evaluated. The coexpression of CFTR and NF-κB was detected in cervical cancer cell lines. Nuclear factor κB signaling was inhibited by siRNA for NF-κB p65 and activated by stimulation of cells with interleukin β or tumor necrosis factor α. RESULTS We found both the membrane expression of CFTR and nuclear translocation of NF-κB p65 were progressively increased from normal cervical tissue, cervical intraepithelial neoplasm, to cervical cancer (overall R² = 0.74, P < 0.001). Cystic fibrosis transmembrane conductance regulator expression and NF-κB activation were also positively associated with stage, histological grade, lymph node metastasis, and invasive interstitial depth. Multivariate analysis showed that coexpression of CFTR and NF-κB was an independent prognostic factor for survival (relative risk, 5.16; P = 0.003). Dual-immunofluorescence analysis showed CFTR and NF-κB were coexpressed in cervical cancer. Studies in vitro revealed that the expression levels of CFTR mRNA and protein were positively related to NF-κB activation. CONCLUSIONS Cystic fibrosis transmembrane conductance regulator and NF-κB were coexpressed in cervical cancer, and the activation of NF-κB mediated the expression of CFTR. Multivariate analysis revealed that coexpression of CFTR and NF-κB was associated with poor prognosis in patients with cervical cancer.

Abstract
OBJECTIVE The objective of this study was to provide further information on the role of personal characteristics and lifestyle factors, including obesity, diabetes, and tobacco smoking, on survival from pancreatic cancer. METHODS We obtained follow-up data of pancreatic cancer patients enrolled in 2 Italian case-control studies. Information on characteristics and habits up to the time of diagnosis was collected by trained interviewers. Vital status was ascertained through population registers and record linkage with health system databases. Hazard ratios (HRs) of all-cause mortality and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models. RESULTS Follow-up information was retrieved for 648 cancer patients. Compared with subjects with body mass index of less than 25 kg/m, the HRs were 1.14 (95% CI, 0.94-1.39) for overweight (ie, 25-29.9 kg/m) and 1.32 (95% CI, 0.98-1.79) for obese (ie, ≥30 kg/m) patients (trend P = 0.046). The HRs were 1.37 (95% CI, 1.14-1.65) for ever, 1.30 (95% CI, 1.03-1.65) for ex-smokers, and 1.42 (95% CI, 1.16-1.73) for current versus never smokers. Increasing amount and duration of smoking were associated with reduced survival after pancreatic cancer. No association emerged with diabetes, alcohol consumption, and diet. CONCLUSIONS Smoking and overweight before diagnosis may play a role in the prognosis of pancreatic cancer, besides its etiology.
