1 Article Female gender may predict response to FOLFIRINOX in patients with unresectable pancreatic cancer: a single institution retrospective review. 2014

Hohla, Florian / Hopfinger, Georg / Romeder, Franz / Rinnerthaler, Gabriel / Bezan, Angelika / Stättner, Stefan / Hauser-Kronberger, Cornelia / Ulmer, Hanno / Greil, Richard. ·Third Medical Department with Hematology, Medical Oncology, Hemostaseology, Rheumatology and Infectious Diseases, Oncologic Center, Center for Clinical Cancer and Immunology Trials, Laboratory of Immunological and Molecular Cancer Research, Paracelsus Medical University of Salzburg, A-5020 Salzburg, Austria. ·Int J Oncol · Pubmed #24247204.

ABSTRACT: FOLFIRINOX is a highly active regimen for the treatment of patients with unresectable pancreatic cancer. However, treatment with FOLFIRINOX is associated with relevant toxicity and predictors for response to therapy are warranted. We retrospectively analyzed 49 patients with unresectable pancreatic cancer treated with FOLFIRINOX in order to evaluate a possible predictive role of clinical parameters and tumor characteristics for response to chemotherapy. Tumor samples were characterized histopathologically before treatment and expression of p53 and Ki67 was analyzed using automated immunohistochemistry. Overall survival (OS) and progression-free survival (PFS) were estimated by the Kaplan-Meier method. The overall objective response rate was 55.1%, the disease control rate was 70.6%. Female gender was associated with a significantly higher disease control rate of 91.7 compared to 48.0% in male patients (p=0.001) which reached 100% in female patients when primarily treated compared to treatment after surgical resection and relapse (77.8%, p=0.057). For all patients median PFS was 3.5 months (95% CI, 2.7-4.3 months) and median OS was 13 months (95% CI, 9.4-16.6 months). Female patients showed a tendency towards a longer median PFS (5.0 months, 95% CI, 3.6-6.4 months) compared to males (3.0 months, 95% CI, 2.4-3.6 months) (p=0.099). Serum levels of CA19.9 and CEA were significantly higher in female patients compared to male patients (p=0.037, p=0.05). Tumors of patients with response to FOLFIRINOX showed a higher expression level of p53 and Ki67 as well as higher serum levels of CA19.9 compared to non-responders, which was statistically not significant. Our study indicates that female gender is a positive predictor for therapy response to FOLFIRINOX in patients with unresectable pancreatic cancer. Female gender in turn was associated with increased levels of tumor markers CEA and CA19.9 and patients with higher serum levels of CA19.9 were more responsive to FOLFIRINOX.

2 Article Malignant biliary stenosis: conventional cytology versus DNA image cytometry. 2011

Binek, Janek / Lindenmann, Nadja / Meyenberger, Christa M / Hell, Margarete / Ulmer, Hanno / Spieler, Peter / Borovicka, Jan. ·Gastroenterology Unit, Department of Internal Medicine, Kantonsspital, 9007, St. Gallen, Switzerland. janek.binek@kssg.ch ·Surg Endosc · Pubmed #21170660.

ABSTRACT: BACKGROUND: The aim of this study is to evaluate the utility of image cytometry (ICM)-DNA analysis on cytological brush specimens in improving the sensitivity and diagnostic accuracy for biliary neoplasias. METHODS: A total of 71 patients with 89 samples of biliary tree brushing from a stenosis were included in this prospective study. Conventional cytology (CC) and DNA ploidy using ICM of the brushing were performed. Benign or malignant findings were confirmed by surgical exploration or a clinical follow-up of at least 12 months. RESULTS: Diagnosis was confirmed by clinical follow-up in 44 cases and surgical investigation or histology in 41 cases. A definitive diagnosis of the smears resulted in 40 malignant and 49 benign diagnoses. The sensitivity was 0.666 for CC and 0.658 for ICM, and the specificity was 0.920 and 0.937, respectively. The positive predictive value (PPV) was 0.866 for CC and 0.900 for ICM. McNemar's test did not reveal a significant difference between CC and ICM (P=0.803). Agreement of the two methods was found in 73 samples, raising specificity to 0.998 but not sensitivity (0.725). CONCLUSIONS: ICM-DNA seems not to improve significantly the PPV and NPV for detecting neoplasias of the biliary tract compared to CC. Nevertheless a clinical advantage can be seen in the agreement of the two methods in diagnosing dysplasia or cancer, since it did not show false positive results.

3 Article Metabolic factors and the risk of pancreatic cancer: a prospective analysis of almost 580,000 men and women in the Metabolic Syndrome and Cancer Project. 2010

Johansen, Dorthe / Stocks, Tanja / Jonsson, Håkan / Lindkvist, Björn / Björge, Tone / Concin, Hans / Almquist, Martin / Häggström, Christel / Engeland, Anders / Ulmer, Hanno / Hallmans, Göran / Selmer, Randi / Nagel, Gabriele / Tretli, Steinar / Stattin, Pär / Manjer, Jonas. ·Department of Surgery, Lund University, Malmö, Sweden. dorthe.johansen@med.lu.se ·Cancer Epidemiol Biomarkers Prev · Pubmed #20826833.

ABSTRACT: BACKGROUND: The aim of this study was to investigate the association between factors in metabolic syndrome (MetS; single and combined) and the risk of pancreatic cancer. METHODS: The Metabolic Syndrome and Cancer Project is a pooled cohort containing data on body mass index, blood pressure, and blood levels of glucose, cholesterol, and triglycerides. During follow-up, 862 individuals were diagnosed with pancreatic cancer. Cox proportional hazards analysis was used to calculate relative risks (RR) with 95% confidence intervals using the above-mentioned factors categorized into quintiles and transformed into z-scores. All z-scores were summarized and a second z-transformation creating a composite z-score for MetS was done. All risk estimates were calibrated to correct for a regression dilution bias. RESULTS: The trend over quintiles was positively associated with the risk of pancreatic cancer for mid-blood pressure (mid-BP) and glucose in men and for body mass index, mid-BP, and glucose in women. The z-score for the adjusted mid-BP (RR, 1.10; 1.01-1.20) and the calibrated z-score for glucose (RR, 1.37; 1.14-1.34) were positively associated with pancreatic cancer in men. In women, a positive association was found for calibrated z-scores for mid-BP (RR, 1.34; 1.08-1.66), for the calibrated z-score for glucose (RR, 1.98; 1.41-2.76), and for the composite z-score for MetS (RR, 1.58; 1.34-1.87). CONCLUSION: Our study adds further evidence to a possible link between abnormal glucose metabolism and risk of pancreatic cancer. IMPACT: To our knowledge, this is the first study on MetS and pancreatic cancer using prediagnostic measurements of the examined factors.
