Pancreatic Cancer
Jemal, CA Cancer J Clin, 2009; Ferlay, Eur J Cancer, 2010
• An important health problem worldwide: – 4th leading cause of cancer related death in
US
– 5th leading cause of cancer related death in Europe
– No significant decrease in cancer death rates for pancreatic cancer in the last 20 years

Pancreatic Cancer
Jemal, CA Cancer J Clin, 2009; Esposito, Ann Surg Oncol, 2008; Popescu & Dumitrascu, Chirurgia, 2011
• An aggressive disease – Diagnosed at advanced stages
• 90-95% locally/ systemically advanced
– 5-year survival rates for all stages: < 5%
• Surgery (i.e., pancreatectomy) represents the
single hope for long-term survival
• Ductal adenocarcinoma: > 90% of the patients

Pancreatic Cancer
• Invasive ductal carcinoma: – Papillary adk
– Tubular adk
– Adenoscuamous carcinoma
– Anaplastic carcinoma • Osteoclast-like giant cell type – better prognosis

Pancreatic Head Cancer (PHC) • PHC frequently extends directly into the
retroperitoneal spaces (PV/ SMV/ SMA)
• Venous invasion is due to tumour location rather than an indicator for aggressive tumour biology – Rationale for PV/ SMV resection – Arterial invasion – a sign of tumour aggressive biology ?
• Incidence of PV/ SMV resection during PD for PHC:
– 2 – 77%
• Incidence of arterial resections during PD for PHC: – < 10%

Principles of PV/ SMV Resection in PD
Lai, Hepatobiliary Pancreat Dis Sci, 2012
• The management of PV/ SMV invasion
depends on:
– The site of tumour invasion
– Length of venous resection
![Page 39: The Value & Limits of Resection in Pancreatic Cancer · 1 The Value & Limits of Resection in Pancreatic Cancer Irinel Popescu, MD, PhD, FACS, FEBS Center of General Surgery and Liver](https://reader033.fdocuments.us/reader033/viewer/2022041812/5e5889cbe121a130e36dd2a3/html5/thumbnails/39.jpg)
39
Principles of PV/ SMV Resection in PD
Lai, Hepatobiliary Pancreat Dis Sci, 2012; Dumitrascu & Popescu, Langenbecks Arch Surg, 2009
• Venous resection at a late stage in order to
reduce time to venous reconstruction
– Posterior approach facilitates
• Graft interposition vs. direct anastomosis
– Direct anastomosis preferred
• Routine heparinization – controversial
![Page 40: The Value & Limits of Resection in Pancreatic Cancer · 1 The Value & Limits of Resection in Pancreatic Cancer Irinel Popescu, MD, PhD, FACS, FEBS Center of General Surgery and Liver](https://reader033.fdocuments.us/reader033/viewer/2022041812/5e5889cbe121a130e36dd2a3/html5/thumbnails/40.jpg)

Technical Principles
• Splenic vein
reconstruction
– Not routinely
– Inferior mesenteric vein
drainage in splenic vein
(48-68%)
– Potential left-side portal
hypertension

Outcomes in PD with PV/ SMV Resection for PHC
• Morbidity: 42% (6 – 67%) vs. 44% – Thromboses rate – 17%
• No differences according to anticoagulation • Higher when synthetic grafts were used • On late onset – recurrence
• Mortality: 3.3 (0 – 14.3%) vs. 3.7%

Establishes invasion in the SMA, that signals an aggressive tumor biology and it is unlikely to be overcame by resection

• Pancreatic cancer – dismal prognosis • Resection is the single hope for long-
term survival
• R0 resection margins the most important determinant of survival

• PV/ SMV involvement is no longer a contraindication for resection but arterial invasion yes
• Surgeon’s experience impact postoperative morbidity and mortality rates – Highly specialized centers and
multidisciplinary teams for better outcome
