ABSTRACT: A meeting of the Australasian Gastro-Intestinal Trials Group (AGITG) was held to develop a consensus statement defining when a patient with pancreatic cancer has disease that is clearly operable, is borderline, or is locally advanced/inoperable. Key issues included the need for multidisciplinary team consensus for all patients considered for surgical resection. Staging investigations, to be completed within 4 weeks of presentation, should include pancreatic protocol computed tomography, endoscopic ultrasound, and, when possible, biopsy. Given marked differences in outcomes, the operability of tumours should be clearly identified by categories: those clearly resectable by standard means (group 1a), those requiring vascular resection but which are clearly operable (group 1b), and those of borderline operability requiring vascular resection (groups 2a and 2b). Patients who may require vascular reconstruction should be referred, before exploration, to a specialist unit. All patients should have a structured pathology report with standardised reporting of all seven surgical margins, which identifies an R0 (no tumour cells within a defined distance of the margin) if all surgical margins are clear from 1 mm. Neo-adjuvant therapy is increasingly recommended for borderline operable disease, while chemotherapy is recommended as initial therapy for patients with unresectable loco-regional pancreatic cancer. The value of adding radiation after initial chemotherapy remains uncertain. A small number of patients may be downstaged by chemoradiation, and trimodality therapy should only be considered as part of a clinical trial. Instituting these recommendations nationally will be an integral part of the process of improving quality of care and reducing geographic variation between centres in outcomes for patients.

3 Article Discovery of diagnostic biomarkers for pancreatic cancer in immunodepleted serum by SELDI-TOF MS. 2012

Xue, Aiqun / Gandy, Robert C / Chung, Liping / Baxter, Robert C / Smith, Ross C. ·Department of Surgery, The University of Sydney, Suite 5 Level 5 North Shore Private Hospital, St Leonards, NSW 2065 Australia. ·Pancreatology · Pubmed #22487522.

ABSTRACT: MOTIVATION: Reports of serum pancreatic cancer (PC) biomarkers using SELDI-TOF MS have been inconsistent because different chip surfaces and interference with high-abundant proteins. This study examines the influence of these factors on the detection of discriminating diagnostic biomarkers. METHODS: Serum from fourteen from patients with PC, disease controls (DC, n = 14) and healthy volunteers (HV, n = 14) were evaluated by SELDI using H50, IMAC, Q10 and CM10 chips. A further evaluation was undertaken after depletion of seven high-abundant proteins using spin cartridges. RESULTS: More protein peaks were detected in whole serum than in depleted serum for IMAC, H50 and Q10 chips: 60 vs 39, 56 vs 48 and 69 vs 65, respectively, while the CM10 found less peaks in serum (27 vs 47 peaks). However, there were more differentially expressed peaks in the depleted serum samples for PC vs DC and PC vs HV samples using the H50, Q10 and CM10 ProteinChip arrays, whereas for IMAC arrays, more discriminating peaks were seen in non-depleted serum. The highly significant peaks observed on Q10, CM10 and H50 are consistent with the previous finding of ApoA-I (m/z 27,910-28000) and ApoA-II (m/z 8758 and 17,240). In addition, a number of new discriminating protein peaks were found on different ProteinChip arrays, notably peaks at m/z 4280 and 7763 on IMAC arrays. CONCLUSION: This study confirms the diagnostic value of ApoA-I&II and identifies further potential diagnostic biomarkers for pancreatic cancer when multiple chip surfaces are used with depletion of the most highly-abundant proteins.

4 Article Discovery of serum biomarkers for pancreatic adenocarcinoma using proteomic analysis. 2010

Xue, A / Scarlett, C J / Chung, L / Butturini, G / Scarpa, A / Gandy, R / Wilson, S R / Baxter, R C / Smith, R C. ·Department of Surgery, University of Sydney, Royal North Shore Hospital, St Leonards, New South Wales 2065, Australia. ·Br J Cancer · Pubmed #20588270.

ABSTRACT: BACKGROUND AND AIMS: The serum/plasma proteome was explored for biomarkers to improve the diagnostic ability of CA19-9 in pancreatic adenocarcinoma (PC). METHODS: A Training Set of serum samples from 20 resectable and 18 stage IV PC patients, 54 disease controls (DCs) and 68 healthy volunteers (HVs) were analysed by surface-enhanced laser desorption and ionisation time-of-flight mass spectrometry (SELDI-TOF MS). The resulting protein panel was validated on 40 resectable PC, 21 DC and 19 HV plasma samples (Validation-1 Set) and further by ELISA on 33 resectable PC, 28 DC and 18 HV serum samples (Validation-2 Set). Diagnostic panels were derived using binary logistic regression incorporating internal cross-validation followed by receiver operating characteristic (ROC) analysis. RESULTS: A seven-protein panel from the training set PC vs DC and from PC vs HV samples gave the ROC area under the curve (AUC) of 0.90 and 0.90 compared with 0.87 and 0.91 for CA19-9. The AUC was greater (0.97 and 0.99, P<0.05) when CA19-9 was added to the panels and confirmed on the validation-1 samples. A simplified panel of apolipoprotein C-I (ApoC-I), apolipoprotein A-II (ApoA-II) and CA19-9 was tested on the validation-2 set by ELISA, in which the ROC AUC was greater than that of CA19-9 alone for PC vs DC (0.90 vs 0.84) and for PC vs HV (0.96 vs 0.90). CONCLUSIONS: A simplified diagnostic panel of CA19-9, ApoC-I and ApoA-II improves the diagnostic ability of CA19-9 alone and may have clinical utility.
