From the Guidelines
Management of a suspected pancreatic mass requires prompt evaluation with cross-sectional imaging, preferably a pancreatic protocol CT scan with contrast or MRI/MRCP if CT is contraindicated, as recommended by the most recent guidelines 1. The initial assessment should include laboratory tests such as complete blood count, liver function tests, CA 19-9 tumor marker, and basic metabolic panel. If imaging confirms a mass, endoscopic ultrasound (EUS) with fine needle aspiration or biopsy should be performed for tissue diagnosis, as it is preferred over percutaneous sampling 2. For jaundiced patients with suspected malignancy, biliary drainage via ERCP with stent placement may be necessary, but ERCP should only be performed if surgery cannot be done expeditiously 2. Multidisciplinary evaluation involving gastroenterology, surgery, oncology, and radiology is essential to determine resectability and treatment options. For potentially resectable masses, surgical consultation should be expedited, as radical surgery is the only curative treatment for pancreatic cancer 3. Unresectable cases typically require oncology referral for chemotherapy consideration. Nutritional support and pain management are important supportive measures. Early diagnosis and treatment are critical as pancreatic cancer has poor outcomes when diagnosed at advanced stages, with surgical resection offering the only potential cure for localized disease. Some key points to consider in the management of suspected pancreatic mass include:
- The role of PET scan is not recommended in the diagnosis of pancreatic cancer 2
- Baseline CA19.9 can be used to guide treatment and follow-up and may have a prognostic value in absence of cholestasis 2
- Biopsy should be restricted to cases where imaging results of a pancreatic lesion are ambiguous, and EUS guided biopsy is preferred 2
From the FDA Drug Label
1. 4 Pancreatic Cancer Gemcitabine Injection is indicated as first-line treatment for patients with locally advanced (nonresectable Stage II or Stage III) or metastatic (Stage IV) adenocarcinoma of the pancreas. The management of suspected pancreatic mass may involve gemcitabine as a first-line treatment for patients with locally advanced or metastatic adenocarcinoma of the pancreas 4.

From the Research
Diagnostic Approach
- A solid pancreatic mass requires a careful diagnostic work-up to determine the underlying cause and guide treatment [ 5 ].
- The diagnostic work-up should include a combination of clinical evaluation, imaging techniques, and operative procedures to characterize the lesion [ 5 ].
Treatment Options
- For localized pancreatic ductal adenocarcinoma, first-line chemotherapy regimens include FOLFIRINOX and gemcitabine plus nab-paclitaxel (GA) [ 6 ].
- FOLFIRINOX has been associated with higher rates of RECIST partial response and subsequent pancreatectomy compared to GA, but overall survival rates are similar [ 6 ].
- For locally advanced, unresectable pancreatic cancer, FOLFIRINOX and gemcitabine plus nab-paclitaxel have similar efficacy and safety profiles [ 7 ].
Second-Line Treatment
- After failure of first-line treatment with nab-paclitaxel plus gemcitabine, second-line fluoropyrimidine-based regimens such as FOLFOX, FOLFIRI, and FOLFIRINOX are feasible and have a manageable toxicity profile [ 8 ].
- Median overall survival from the start of first-line chemotherapy was significantly better in patients receiving FOLFIRI after nab-paclitaxel plus gemcitabine failure [ 8 ].
Real-World Evidence
- A real-world study comparing first-line gemcitabine plus nab-paclitaxel versus FOLFIRINOX for metastatic pancreatic cancer found similar overall survival rates, but higher rates of adverse events with FOLFIRINOX [ 9 ].
