Pancreatic Cancer
A serious cancer that often presents late. Early detection in high-risk groups (family history, certain genetic syndromes, IPMN) is improving outcomes. New chemotherapy and targeted therapies are extending survival.

This article is educational and does not replace your doctor's advice. Seek urgent care for any red-flag symptoms.
What is it?
Pancreatic cancer most often arises in the head of the pancreas (closer to the bile duct). Most are pancreatic ductal adenocarcinoma (PDAC) — aggressive and difficult to detect early. A smaller fraction are neuroendocrine tumors (better prognosis).
How common is it?
Lifetime risk ~1 in 65. Saudi rates rising slowly. Mostly affects people over 60. Risk factors: smoking (doubles risk), chronic pancreatitis, diabetes, obesity, family history, BRCA1/2 and Lynch syndrome carriers, IPMN.
Why does it happen?
Genetic mutations accumulate over years. Most common driver: KRAS mutation. Smoking is the largest modifiable risk factor. Family history of pancreatic, breast, ovarian, or colorectal cancer increases risk.
Symptoms
- Painless jaundice — yellow eyes/skin without significant pain (head of pancreas tumors)
- Dull abdominal pain that radiates to the back
- Unexplained weight loss
- New-onset diabetes after age 50 with weight loss
- Pale stools, dark urine
- Itching from bile blockage
- Fatigue, loss of appetite
Red flags — seek urgent medical care
Painless jaundice over weeks
Pancreatic cancer until proven otherwise — needs urgent imaging.
New-onset diabetes with weight loss in someone over 50
Investigate the pancreas.
How is it diagnosed?
Triple-phase CT or MRI of the pancreas with contrast. EUS with biopsy provides tissue diagnosis. CA 19-9 blood test is a tumor marker (not specific). Staging: CT chest/abdomen/pelvis ± PET. Genetic testing if family history.
What the latest science says
FOLFIRINOX and gemcitabine-nab-paclitaxel chemotherapy regimens improved survival. Olaparib for BRCA-mutated tumors. Pembrolizumab for MSI-high tumors. Neoadjuvant treatment now standard for borderline-resectable disease.
Outlook — what to expect
Stage at diagnosis matters enormously. Stage I (resectable, found early): 5-year survival 30-40%. Stage IV: median survival 6-11 months. Most patients are diagnosed at stage III or IV. Advances in treatment are slowly improving outcomes.
Treatment
Habits & Lifestyle
Prevention is best — reduce modifiable risks.
- Don't smoke — most important risk factor.
- Maintain healthy weight.
- Limit alcohol.
- Manage diabetes well.
- If family history of pancreatic, breast, ovarian, colorectal cancer: ask about genetic testing and surveillance.
Diet
Mediterranean pattern; for those undergoing treatment, nutrition support is critical.
- Adequate protein and calories during treatment.
- Pancreatic enzymes if exocrine insufficiency.
- See a dietitian familiar with cancer care.
Medications
Chemotherapy regimens have improved.
- FOLFIRINOX (combination chemotherapy) — first-line for fit patients with metastatic or locally advanced disease.
- Gemcitabine + nab-paclitaxel — alternative.
- Olaparib (PARP inhibitor) for BRCA-mutated tumors after platinum chemotherapy.
- Pembrolizumab for MSI-high or mismatch-repair-deficient tumors.
- Pancreatic enzyme replacement for malabsorption.
Procedures & Surgery
Surgery offers the only chance of cure for early disease.
- Whipple procedure (pancreaticoduodenectomy) — for tumors in the head of the pancreas.
- Distal pancreatectomy — for body/tail tumors.
- Biliary stenting via ERCP for jaundice in inoperable disease.
- Celiac plexus block for pain control.
In the Saudi context
Saudi tertiary centers have high-volume pancreatic surgery programs (KFSH, KFMC, KAU). Surgical outcomes correlate strongly with surgeon volume. Several centers offer multidisciplinary tumor boards.

- Is my tumor resectable?
- Should I have my tumor tested for BRCA, MSI, and other genetic markers?
