Pancreatic Cancer: Symptoms, Diagnosis and Treatment Decisions
Pancreatic cancer is a malignant tumour arising from pancreatic tissue, most often in the head of the pancreas. Because early disease may cause no symptoms, it is frequently detected when weight loss, loss of appetite, back-radiating abdominal pain or painless jaundice appear. Treatment planning never rests on a single test: imaging, tissue diagnosis, general condition and coexisting illnesses are weighed together. In Antalya, Dr. Gökhan ATEŞ provides information on how the diagnostic pathway proceeds and which criteria guide the decision about surgery.

Pancreatic cancer often develops without early symptoms, so the extent of disease at diagnosis varies from person to person. Diagnosis rests on pancreas-protocol contrast-enhanced CT, supplemented where needed by MRI/MRCP and by endoscopic ultrasound (EUS) with tissue sampling. Surgery is considered only in selected cases where imaging suggests the tumour can be removed completely; in borderline resectable disease, systemic (neoadjuvant) treatment may be considered first. The decision is made by a multidisciplinary team (MDT) including surgery, medical oncology, radiology, gastroenterology and pathology. CA 19-9 is not a diagnostic or population screening test.
What are the symptoms?
Symptoms depend on where the tumour sits. Tumours in the head of the pancreas narrow the bile duct early and often present with painless jaundice, itching, dark urine and pale stools. Tumours of the body and tail may remain silent for longer.
- Yellowing of the eyes and skin, itching, dark urine, pale stools
- Persistent dull upper abdominal pain radiating to the back
- Unintentional weight loss and loss of appetite
- Greasy, foul-smelling, floating stools (impaired fat absorption)
- New-onset diabetes or sudden loss of diabetic control
- Nausea, early fullness, fatigue
Risk factors
Having a risk factor does not mean the disease will develop, and many patients have no identifiable risk factor at all. Smoking, long-standing chronic pancreatitis, older age, obesity and certain familial or genetic conditions are among the recognised factors. Where there is a family history, surveillance is discussed together with genetic counselling.
How is it diagnosed?
The backbone of diagnosis is pancreas-protocol (thin-slice, multiphase) contrast-enhanced CT. It shows both the mass and its relationship to the surrounding arteries and veins, which is decisive for the surgical decision. MRI and MRCP complement this by characterising liver lesions and the ductal anatomy.
Endoscopic ultrasound (EUS) helps visualise small lesions and allows needle sampling. Tissue diagnosis is generally required when systemic treatment is planned before surgery. If jaundice is present, endoscopic stenting to relieve bile flow is considered according to the treatment plan.
The CA 19-9 blood test is not diagnostic. It can rise in benign biliary obstruction and may remain normal in some people despite a tumour. It is therefore not used for screening, but may help monitor the course of treatment.
Tests and what they are for
| Test | Purpose | Note |
|---|---|---|
| Pancreas-protocol CT | Mass, vascular relationship, distant spread | Core study for the surgical decision |
| MRI / MRCP | Liver lesions, ductal anatomy | Complements CT |
| EUS ± biopsy | Small lesions, tissue diagnosis | Especially before systemic therapy |
| PET-CT | Suspected wider spread in selected cases | Not routine |
| CA 19-9 | Supportive marker during follow-up | Not a diagnostic or screening test |
| Liver tests, bilirubin | Biliary obstruction | Guides management of jaundice |
Resectability: who may be offered surgery?
Surgery can be considered when the tumour is technically removable in its entirety and the patient is fit enough for a major operation. Imaging findings are grouped into three broad categories: resectable, borderline resectable, and locally advanced or metastatic.
In resectable disease the team discusses upfront surgery versus systemic treatment first. In borderline resectable disease, chemotherapy (with radiotherapy where indicated) is usually given first and surgery is reconsidered if the response is adequate. Where there is distant spread, treatment is planned around systemic and supportive care; any procedure then aims to relieve jaundice or gastric outlet obstruction rather than to remove the tumour.
- The tumour's relationship to major arteries and veins is decisive
- Resection is not appropriate when distant metastases are present
- Age alone is not a criterion; fitness and comorbidity are assessed together
- Assessment is repeated during treatment and the plan may change
Why the multidisciplinary team matters
There is no single correct sequence in pancreatic cancer. A team meeting bringing together surgery, medical and radiation oncology, radiology, gastroenterology, pathology and nutrition support reviews the imaging, the tissue diagnosis, the patient's performance status and their preferences together. The sequence of treatment for the same patient may be updated as the situation evolves.
Surgical options
The type of operation follows the site and extent of the tumour. Treatment after surgery is completed according to the pathology of the removed tissue.
- Pancreatoduodenectomy (Whipple procedure) for tumours of the head
- Distal pancreatectomy for body and tail tumours, with splenectomy where required
- Total pancreatectomy in selected cases of extensive involvement
- Procedures to relieve jaundice or gastric outlet obstruction when resection is not appropriate
What to expect after surgery
After pancreatic surgery, nutrition is reintroduced step by step, pancreatic enzyme support is provided where needed, and blood glucose is monitored. Weight monitoring and dietitian support are a normal part of the pathway. Oncological treatment, if required, is timed according to recovery.
