ADJUVANT CHEMOTHERAPY
Rationale for adjuvant therapy
• 80% will relapse within 1-2 years of surgery
• Disease progression occurs at both local and distant sites

• Overall survival favours those who
complete all six cycles of treatment
(HR 0.52; 95% CI (0.44-0.60);
p<0.01)
• No difference in survival if chemo
delayed up to 12 weeks
(HR 0.99; 95% CI (0.95-1.02))

DEVELOPING AREAS OF WORK
Downstaging chemotherapy
Early Locally advanced Metastatic
Downstaging
chemotherapy
• Conversion from unresectable or borderline resectable
state to resectable disease
• Increase rate of R0 resections
Downstaging chemotherapy
• Not a new approach!
Downstaging chemotherapy
• All retrospective and prospective studies of neoadjuvant therapy
in patients with pancreatic or periampullary cancers (1980-2009)
• 111 studies (4,394 patients)
Systematic review
PLoS Med 2010; 7(4): e1000267
• All retrospective and prospective studies of neoadjuvant therapy
in patients with pancreatic or periampullary cancers (1980-2009)
• 111 studies (4,394 patients)
• Patients who become resectable after neoadjuvant therapy
have comparable survival to those who were initially
resectable
Systematic review
PLoS Med 2010; 7(4): e1000267
• Improved imaging – high resolution CT/MRI
• Improved surgery – vascular resection
• Improved chemotherapy
Downstaging chemo – a renaissance
Personalised medicine
PRECISION PANC
Immunotherapy…is there a role?

Summary
• Current standard of care treatment informed by evidence base
and endorsed by NICE guidelines.
