This summary provides information about the treatment of exocrine pancreatic cancer.
Estimated new cases and deaths from pancreatic cancer in the United States in 2024:[1]
The incidence of pancreatic cancer has markedly increased over the past several decades. In the United States, it ranks as the fourth leading cause of cancer death in men and the third leading cause of cancer death in women.[1] Despite the high mortality rate associated with pancreatic cancer, its etiology is poorly understood.
Risk factors for development of pancreatic cancer include the following:[2,3]
Cancers of the pancreas are commonly identified by the site of involvement within the pancreas. Surgical approaches differ for masses in the head, body, tail, or uncinate process of the pancreas.
Pancreatic cancer symptoms depend on the site of the tumor within the pancreas and the degree of tumor involvement.
In the early stages of pancreatic cancer, there are not many noticeable symptoms. As the cancer grows, symptoms may include the following:
Pancreatic cancer is difficult to detect and diagnose for the following reasons:
To appropriately treat pancreatic cancer, it is crucial to evaluate whether the cancer can be resected.
Imaging tests may help diagnose pancreatic cancer and identify patients with disease that is not amenable to resection. Imaging tests may include the following:[4]
In a case series of 228 patients, positive peritoneal cytology had a positive predictive value of 94%, specificity of 98%, and sensitivity of 25% for determining unresectability.[7]
No tumor-specific markers exist for pancreatic cancer. Markers such as serum cancer antigen (CA) 19-9 have low specificity. Most patients with pancreatic cancer have an elevated CA 19-9 level at diagnosis. Increased CA 19-9 levels during or after definitive therapy may identify patients with progressive tumor growth.[8][Level of evidence C2] However, the presence of a normal CA 19-9 level does not preclude recurrence.
The primary factors that influence prognosis are:
Exocrine pancreatic cancer is rarely curable and has an overall survival (OS) rate of less than 6%.[9] As pancreatic cancer is associated with significant morbidity and mortality, and treatment decisions are complex, management with a comprehensive multidisciplinary team should be considered.
The highest cure rate occurs when the tumor is truly localized to the pancreas; however, this stage of disease accounts for less than 20% of cases. For patients with localized disease and small cancers (<2 cm) with no lymph node metastases and no extension beyond the capsule of the pancreas, complete surgical resection is associated with an actuarial 5-year survival rate of 18% to 24%.[10][Level of evidence C1]
Surgical resection is the mainstay of curative treatment and provides a survival benefit in patients with small, localized pancreatic tumors, but it should be considered only alongside systemic therapy. Patients with unresectable, metastatic, or recurrent disease are unlikely to benefit from surgical resection.
Patients with any stage of pancreatic cancer are candidates for clinical trials because of the poor response to chemotherapy, radiation therapy, and surgery as conventionally used.
Information about ongoing clinical trials for pancreatic cancer is available from the NCI website.
Palliation of symptoms may be achieved with conventional treatment (systematic chemotherapy).
Palliative measures that may improve quality of life without affecting OS include the following:[11,12]
Pancreatic cancer includes the following carcinomas:
Malignant
Borderline Malignancies
The staging system for pancreatic exocrine cancer continues to evolve. Clinical staging is guided by resectability, which is strongly influenced by surgical judgment. Consensus guidelines for surgical resectability (e.g., National Comprehensive Cancer Network, MD Anderson Cancer Center, American Hepato-Pancreato-Biliary Association, and International Hepato-Pancreato-Biliary Association) continue to be refined, but are traditionally stratified by the following:
The American Joint Committee on Cancer (AJCC) has designated staging by TNM (tumor, node, metastasis) classification.[1]

Surgical resection, when feasible, remains the primary treatment modality for patients with pancreatic cancer. On occasion, resection can lead to long-term survival and provides effective palliation.[1-3][Level of evidence C1] Treatment is often guided by resectability, but this may vary depending on surgical judgment and experience. Referral to a high-volume center should be considered.[4]
The addition of postoperative chemotherapy improves overall survival, but the role of chemoradiation remains controversial.
Complications of pancreatic cancer include the following:
The survival rate of patients with any stage of pancreatic exocrine cancer is poor. Clinical trials are appropriate alternatives for treatment of patients with any stage of disease and should be considered before palliative approaches are selected.
Information about ongoing clinical trials for pancreatic cancer is available from the NCI website.
Clinical Stage | Treatment Options |
---|---|
Resectable or borderline resectable pancreatic cancer | Neoadjuvant therapy |
Surgery | |
Postoperative chemotherapy | |
Postoperative chemoradiation therapy | |
Preoperative chemotherapy and/or radiation therapy (under clinical evaluation) | |
Alternative radiation techniques (under clinical evaluation) | |
Locally advanced pancreatic cancer | Chemotherapy with or without targeted therapy |
Chemoradiation therapy | |
Surgery | |
Palliative surgery | |
Clinical trials evaluating novel agents in combination with chemotherapy or chemoradiation therapy for patients with unresectable tumors | |
Intraoperative radiation therapy and/or implantation of radioactive sources (under clinical evaluation) | |
Metastatic or recurrent pancreatic cancer | Chemotherapy with or without targeted therapy |
Clinical trials evaluating new anticancer agents alone or in combination with chemotherapy |
Palliative therapies can be considered in patients with any stage of disease. For more information, see the Palliative Therapy section.
The DPYD gene encodes an enzyme that catabolizes pyrimidines and fluoropyrimidines, like capecitabine and fluorouracil. An estimated 1% to 2% of the population has germline pathogenic variants in DPYD, which lead to reduced DPD protein function and an accumulation of pyrimidines and fluoropyrimidines in the body.[5,6] Patients with the DPYD*2A variant who receive fluoropyrimidines may experience severe, life-threatening toxicities that are sometimes fatal. Many other DPYD variants have been identified, with a range of clinical effects.[5-7] Fluoropyrimidine avoidance or a dose reduction of 50% may be recommended based on the patient's DPYD genotype and number of functioning DPYD alleles.[8-10] DPYD genetic testing costs less than $200, but insurance coverage varies due to a lack of national guidelines.[11] In addition, testing may delay therapy by 2 weeks, which would not be advisable in urgent situations. This controversial issue requires further evaluation.[12]
Treatment options for resectable or borderline resectable pancreatic cancer include the following:
Palliative therapies can be considered in patients with any stage of disease. For more information, see the Palliative Therapy section.
Neoadjuvant therapy is chemotherapy with or without chemoradiation therapy given before surgery. The role of neoadjuvant therapy has been evaluated in retrospective studies (Surveillance, Epidemiology, and End Results [SEER] Program database and National Cancer Database) and is recommended by multiple consensus guidelines for the management of patients with borderline resectable pancreatic cancer. It is being evaluated in patients with resectable or borderline resectable pancreatic cancer in several ongoing trials.[9-11]
Evidence (neoadjuvant chemotherapy with or without chemoradiation therapy):
The optimal neoadjuvant therapy regimen is unknown, and additional chemotherapy regimens are being evaluated in the following trials: ALLIANCE (NCT04340141), PREOPANC-3 (NCT04927780), PANACHE-01-PRODIGE (NCT02959879), and NorPACT-01 (NCT02919787).
Complete resection can yield 5-year survival rates of 18% to 24%, but ultimate control remains poor because of the high incidence of both local and distant tumor recurrence. Thus, systemic therapy is also recommended for treatment.[14-16][Level of evidence C1]
Approximately 20% of patients present with pancreatic cancer amenable to local surgical resection, with operative mortality rates of approximately 1% to 16%.[17-21] Using information from the Medicare claims database, a national cohort study of more than 7,000 patients undergoing pancreaticoduodenectomy between 1992 and 1995 revealed higher in-hospital mortality rates at low-volume hospitals (<1 pancreaticoduodenectomy per year) versus high-volume hospitals (>5 per year) (16% vs. 4%, respectively; P < .01).[17]
Historically, multiple randomized trials have established that adjuvant gemcitabine monotherapy [22] or adjuvant 5-FU monotherapy [3] improve OS for 6 months after surgical resection compared with surgery alone. More recent studies have looked at newer combination regimens that might further improve outcomes after surgical resection.
For patients with good performance status, adjuvant FOLFIRINOX chemotherapy or the combination of gemcitabine and capecitabine should be considered. However, for older patients or patients with marginal performance status, adjuvant gemcitabine or 5-FU monotherapy can be considered. In Asia, S-1 (tegafur, gimeracil, and oteracil potassium) is an appropriate alternative to gemcitabine-based therapies.
Evidence (postoperative chemotherapy):
The role of postoperative therapy (chemotherapy with or without chemoradiation therapy) in the management of this disease remains controversial because much of the randomized clinical trial data available are statistically underpowered and provide conflicting results.[4-8]
Evidence (postoperative chemoradiation therapy):
Several phase III trials examined the potential OS benefit of postoperative adjuvant 5-FU–based chemoradiation therapy:
The EORTC/U.S. Gastrointestinal Intergroup RTOG-0848 phase III adjuvant trial evaluating the impact of chemoradiation therapy after completion of a full course of gemcitabine with or without erlotinib has closed and results are pending.
Additional trials are still warranted to determine more effective systemic therapy for this disease.

While locally advanced and metastatic pancreatic cancer are both incurable, the natural history of locally advanced disease may be different than it is for metastatic disease. An autopsy series demonstrated that 30% of patients presenting with locally advanced disease died without evidence of distant metastases.[1][Level of evidence A1] Therefore, investigators have struggled to determine whether chemoradiation therapy for patients presenting with locally advanced disease is warranted.
Treatment options for locally advanced pancreatic cancer include the following:
Palliative therapies can be considered in patients with any stage of disease. For more information, see the Palliative Therapy section.
Chemotherapy is the primary treatment modality for patients with locally advanced pancreatic cancers and uses the same regimens as those used to treat patients with metastatic disease.
Evidence (chemotherapy):
The role of chemoradiation in locally advanced pancreatic cancer remains controversial. Table 7 summarizes phase III randomized studies of chemoradiation for locally advanced pancreatic cancer.

Evidence (chemoradiation therapy):
Three trials evaluated combined modality therapy versus radiation therapy alone.[16-18] The trials had substantial deficiencies in design or analysis. Initially, the standard of practice was to give chemoradiation therapy based on data from the first two studies. However, with the publication of the third study, standard practice changed to chemotherapy followed by chemoradiation in the absence of metastases.
The LAP07 study represents the most robust, prospective, randomized phase III data regarding the role of chemoradiation therapy in the setting of gemcitabine-based induction chemotherapy that demonstrates no OS benefit. However, this study was initiated before the advent of FOLFIRINOX chemotherapy, which has been widely adopted into the locally advanced setting. The role of chemoradiation in the setting of more active chemotherapy regimens, including gemcitabine/paclitaxel and FOLFIRINOX, has yet to be evaluated.
Patients with locally advanced pancreatic cancer have tumors that are technically unresectable because of local vessel impingement or invasion by tumor. However, with the combination of chemotherapy and chemoradiation therapy, some patients may become candidates for radical pancreatic resection.
A significant proportion (approximately one-third) of patients with pancreatic cancer present with locally advanced disease. Patients may benefit from palliation of biliary obstruction by endoscopic, surgical, or radiological means.[24]

Treatment options for metastatic or recurrent pancreatic cancer include the following:
Palliative therapies can be considered in patients with any stage of disease. For more information, see the Palliative Therapy section.
Because of the low objective response rate and limited efficacy of palliative chemotherapy regimens, all newly diagnosed patients should consider enrolling in clinical trials. Multiagent chemotherapy combinations have been shown to prolong outcomes compared with single-agent gemcitabine.[1-3]
Evidence (single-agent chemotherapy):
Evidence (multiagent chemotherapy):
Based on this trial, NALIRIFOX is a standard first-line treatment option for patients with advanced pancreatic cancer.
Evidence (second-line chemotherapy):
The following results were observed:
Germline mutations in BRCA1 or BRCA2 are present in 4% to 8% of patients with pancreatic adenocarcinoma.[11,12] BRCA1/BRCA2 encode for proteins in the homologous repair pathway and DNA double-stranded break repair, and thus may be more sensitive to further DNA damage. Pancreatic tumors with BRCA1/BRCA2 mutations demonstrate improved responses to platinum-based therapies.[13] Poly (ADP-ribose) polymerase (PARP) inhibition has been posited to act synergistically with BRCA1/BRCA2 mutations by inhibiting single-stranded break repair. Several PARP inhibitors have been approved for treatment of patients with BRCA1/BRCA2-mutated advanced ovarian and breast cancers and are actively being studied for the management of patients with BRCA1/BRCA2-mutated pancreatic adenocarcinoma.
Olaparib (a PARP inhibitor) maintenance therapy can be considered for patients with germline BRCA1/BRCA2 mutations and metastatic pancreatic adenocarcinoma who have responded to first-line platinum-based therapy for more than 4 months.
