Purpose of This PDQ Summary

This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about the treatment of pancreatic cancer. This summary is reviewed regularly and updated as necessary by the PDQ Adult Treatment Editorial Board ¹.

Information about the following is included in this summary:

• Epidemiology and diagnosis.
• Cellular classification.
• Staging.
• Treatment options by cancer stage.

This summary is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.

Some of the reference citations in the summary are accompanied by a level-of-evidence designation. These designations are intended to help readers assess the strength of the evidence supporting the use of specific interventions or approaches. The PDQ Adult Treatment Editorial Board uses a formal evidence ranking system ² in developing its level-of-evidence designations. Based on the strength of the available evidence, treatment options are described as either “standard” or “under clinical evaluation.” These classifications should not be used as a basis for reimbursement determinations.

This summary is also available in a patient version ³, written in less technical language, and in Spanish ⁴.

General Information

Note: Information on pancreatic cancer in children is available in the PDQ summary on Unusual Cancers of Childhood ⁵.

Note: Estimated new cases and deaths from pancreatic cancer in the United States in 2008:[1]

• New cases: 37,680.
• Deaths: 34,290.

Note: Some citations in the text of this section are followed by a level of evidence. The PDQ editorial boards use a formal ranking system to help the reader judge the strength of evidence linked to the reported results of a therapeutic strategy. (Refer to the PDQ summary on Levels of Evidence ² for more information.)

Carcinoma of the pancreas has had a markedly increased incidence during the past several decades and ranks as the fourth leading cause of cancer death in the United States. Despite the high mortality rate associated with pancreatic cancer, its etiology is poorly understood.[2] Cancer of the exocrine pancreas is rarely curable and has an overall survival (OS) rate of less than 4%.[3] The highest cure rate occurs if the tumor is truly localized to the pancreas; however, this stage of the disease accounts for fewer than 20% of cases. For those 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 can yield actuarial 5-year survival rates of 18% to 24%.[4][Level of evidence: 3iA] Improvements in imaging technology, including spiral computed tomographic scans, magnetic resonance imaging scans, positron emission tomographic scans, endoscopic ultrasound examination, and laparoscopic staging can aid in the diagnosis and the identification of patients with disease that is not amenable to resection.[5] 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.[6] For patients with advanced cancers, the OS rate of all stages is less than 1% at 5 years with most patients dying within 1 year.[7-10]

No tumor-specific markers exist for pancreatic cancer; markers such as serum CA 19-9 have low specificity. Most patients with pancreatic cancer will have an elevated CA 19-9 at diagnosis. Following or during definitive therapy, the increase of CA 19-9 levels may identify patients with progressive tumor growth.[11][Level of evidence: 3iDiii] The presence of a normal CA 19-9, however, does not preclude recurrence.

Patients with any stage of pancreatic cancer can appropriately be considered candidates for clinical trials because of the poor response to chemotherapy, radiation therapy, and surgery as conventionally used. Palliation of symptoms, however, may be achieved with conventional treatment. Symptoms caused by pancreatic cancer may depend on the site of the tumor within the pancreas and the degree of involvement. Palliative surgical or radiologic biliary decompression, relief of gastric outlet obstruction, and pain control may improve the quality of life while not affecting OS.[12,13] Palliative efforts may also be directed to the potentially disabling psychological events associated with the diagnosis and treatment of pancreatic cancer.[14]

Information about ongoing clinical trials is available from the NCI Web site ⁶.

Stage Information

The staging system for pancreatic exocrine cancer continues to evolve. The importance of staging beyond that of resectable and unresectable is uncertain since state-of-the-art treatment has demonstrated little impact on survival. To communicate a uniform definition of disease, however, knowledge of the extent of the disease is necessary. 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.

The American Joint Committee on Cancer (AJCC) has designated staging by TNM classification.[1]

Primary tumor (T)

• TX: Primary tumor cannot be assessed
• T0: No evidence of primary tumor
• Tis: Carcinoma in situ
• T1: Tumor is limited to the pancreas and is 2 cm or less in greatest dimension
• T2: Tumor is limited to the pancreas and is more than 2 cm in greatest dimension
• T3: Tumor extends beyond the pancreas but without involvement of the celiac axis or the superior mesenteric artery
• T4: Tumor involves the celiac axis or the superior mesenteric artery (unresectable primary tumor)

Regional lymph nodes (N)

• NX: Regional lymph nodes cannot be assessed
• N0: No regional lymph node metastasis
• N1: Regional lymph node metastasis

Distant metastasis (M)

• MX: Distant metastasis cannot be assessed
• M0: No distant metastasis
• M1: Distant metastasis

Stage 0

• Tis, N0, M0

Stage IA

• T1, N0, M0

Stage IB

• T2, N0, M0

Stage IIA

• T3, N0, M0

Stage IIB

• T1, N1, M0
• T2, N1, M0
• T3, N1, M0

Stage III

Treatment Option Overview

Note: Some citations in the text of this section are followed by a level of evidence.

(Refer to the PDQ summary on Levels of Evidence ² for more information.)

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 prior to selecting palliative approaches. To provide optimal palliation, determination of resectability must be made. Staging studies for resectability include helical computed tomographic scan, magnetic resonance imaging scan, and endoscopic ultrasound. The introduction of minimally invasive techniques, such as laparoscopy and laparoscopic ultrasound, may decrease the use of laparotomy.[1,2] Surgical resection remains the primary modality when feasible since, on occasion, resection can lead to long-term survival and provides effective palliation.[3-5][Level of evidence: 3iA] 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.[6-10] Frequently, malabsorption caused by exocrine insufficiency contributes to malnutrition. Attention to pancreatic enzyme replacement can help alleviate this problem. (Refer to the PDQ summary on Nutrition in Cancer Care ⁸ for more information.) Celiac axis (and intrapleural) nerve blocks can provide highly effective and long-lasting control of pain for some patients.

Stage I and II Pancreatic Cancer

Note: Some citations in the text of this section are followed by a level of evidence. The PDQ editorial boards use a formal ranking system to help the reader judge the strength of evidence linked to the reported results of a therapeutic strategy. (Refer to the PDQ summary on Levels of Evidence ² for more information.)

Approximately 20% of patients present with pancreatic cancer amenable to local surgical resection, with operative mortality rates of approximately 1% to 16%.[1-5] 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).[1] 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.[6-8][Level of evidence: 3iA] The role of postoperative therapy (chemotherapy with or without chemoradiation therapy [CRT]) in the management of this disease remains controversial because much of the randomized clinical trial data available are statistically underpowered and provide conflicting results.[9-13]

Three phase III trials examined the potential overall survival (OS) benefit of postoperative adjuvant 5-fluorouracil (5-FU)–based CRT. A small randomized trial conducted by the Gastrointestinal Study Group (GITSG) in 1985 demonstrated a significant but modest improvement in median-term and long-term survival over resection alone with postoperative bolus 5-FU and regional split course radiation given at a dose of 40 Gy.[9][Level of evidence: 1iiA];[10][Level of evidence: 2A] An attempt by the European Organization for the Research and Treatment of Cancer to reproduce the results of the GITSG trial failed to confirm a significant benefit for adjuvant CRT over resection alone;[11][Level of evidence: 1iiA] however, this trial treated patients with pancreatic as well as periampullary cancers (with a potential better prognosis). A subset analysis of the patients with primary pancreatic tumors indicated a trend towards improved median, 2-year, and 5-year OS with adjuvant therapy compared with surgery alone (17.1 months, 37% and 20% vs. 12.6 months, 23% and 10%, P = .09 for median survival). An updated analysis of a subsequent European Study for Pancreatic Cancer (ESPAC 1) trial examined only patients who underwent strict randomization following pancreatic resection. The patients were assigned to one of four groups (observation, bolus 5-FU chemotherapy, bolus 5-FU CRT, or CRT followed by additional chemotherapy). With a 2 × 2 factorial design reported, at a median follow-up of 47 months, a median survival benefit was observed for only the patients who received postoperative 5-FU chemotherapy. These results were difficult to interpret, however, because of a high rate of protocol nonadherence and the lack of a separate analysis for each of the four groups in the 2 x 2 design.[12-14][Level of evidence: 1iiA]

The United States Gastrointestinal Intergroup has reported the results of a randomized phase III trial (RTOG-9704 ⁹) that included 451 patients with resected pancreatic cancers who were assigned to receive either postoperative infusional 5-FU plus infusional 5-FU and concurrent radiation or adjuvant gemcitabine plus infusional 5-FU and concurrent radiation.[15] The primary endpoints were OS for all patients and OS for patients with pancreatic head cancers. The median OS for the 388 patients with pancreatic head tumors was 20.5 months in the gemcitabine arm versus 16.9 months in the 5-FU arm; 3-year survival was 31% versus 22%, respectively (P = .09; hazard ratio = 0.82; confidence interval [CI], 0.65–1.03). OS for all patients was not reported in the publication; however, median survival estimates extrapolated from the presented survival curve were approximately 19 months for the gemcitabine group and 17 months for the 5-FU group.[15][Level of evidence: 1iiA]

Results have also been reported from CONKO-001, a multicenter phase III trial of 368 patients with resected pancreatic cancer who were randomly assigned to six cycles of adjuvant gemcitabine versus observation.[16] In contrast to the previous trials, the primary endpoint was disease-free survival (DFS). Median DFS was 13.4 months in the gemcitabine arm (95% CI, 11.4–15.3) and 6.9 months in the observation group (95% CI, 6.1–7.8; P < .001). However, there was no significant difference in OS between the gemcitabine arm (median 22.1 months, 95% CI, 18.4–25.8) and the control group (median 20.2 months, 95% CI, 17–23.4).[16][Level of evidence: 1iiDii]

Although the available data do not resolve the controversy of the optimal adjuvant therapy strategy for patients with resected pancreatic cancer, the results of CONKO-001 and RTOG-9704 suggest that a gemcitabine-containing platform represents an appropriate choice for current management and may be considered as a building block for future clinical trials.

Additional trials are still warranted to determine more effective adjuvant therapy for this disease.

Standard treatment options:

1. Radical pancreatic resection:
   • Whipple procedure (pancreaticoduodenal resection).
   • Total pancreatectomy when necessary for adequate margins.
   • Distal pancreatectomy for tumors of the body and tail of the pancreas.[17,18]



2. Radical pancreatic resection with or without postoperative 5-FU chemotherapy and radiation therapy.[9-13]

Treatment options under clinical evaluation:

1. For patients with resected tumors, postoperative radiation therapy with other chemotherapeutic agents.



2. For patients with resected tumors, postoperative chemotherapy alone. The ESPAC-3 ¹⁰ trial is evaluating postoperative chemotherapy with either 5-FU/leucovorin or gemcitabine versus no additional treatment.[19] Results are pending.

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with stage I pancreatic cancer ¹¹ and stage II pancreatic cancer ¹². The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site ⁶.

Stage III Pancreatic Cancer

Note: Some citations in the text of this section are followed by a level of evidence. The PDQ editorial boards use a formal ranking system to help the reader judge the strength of evidence linked to the reported results of a therapeutic strategy. (Refer to the PDQ summary on Levels of Evidence ² for more information.)

Patients with stage III pancreatic cancer have tumors that are technically unresectable because of local vessel impingement or invasion by tumor. These patients may benefit from palliation of biliary obstruction by endoscopic, surgical, or radiological means.[1]

Three trials attempted to look at issues of combined modality therapy versus radiation therapy alone (the Gastrointestinal Tumor Study Group's GITSG-9173 ¹⁴ trial, the Eastern Cooperative Oncology Group's E-8282 ¹⁵ trial, and the Federation Francophone de Cancerologie Digestive-Société Française de Radiothérapie Oncologie group's FFCD-SFRO ¹⁶ trial ).[2-4] The three trials had substantial deficiencies in design or analysis. Until recently, the standard of practice has been to give chemoradiation therapy, and that was based on the first two studies; however, with the preliminary publication of the third study, standard practice has changed.

Prior to the use of gemcitabine for patients with locally advanced or metastatic pancreatic cancer, investigators from the GITSG randomly assigned 106 patients with locally advanced pancreatic adenocarcinoma to receive external beam radiation therapy (EBRT) (60 Gy) alone or to receive concurrent EBRT (either 40 Gy or 60 Gy) plus bolus fluorouracil (5-FU).[2][Level of evidence: 1iiA] The study was stopped early when the chemoradiation therapy arms were found to have better efficacy. The 1-year survival was 11% for patients who received EBRT alone compared with 38% for patients who received chemoradiation with 40 Gy and 36% for patients who received chemoradiation with 60 Gy. After an additional 88 patients were enrolled in the combined modality arms, there was a trend toward improved survival with 60 Gy EBRT plus 5-FU, but the difference in time-to-progression and overall survival (OS) was not statistically significant when compared to the 40 Gy arm.[5]

In contrast, investigators from the ECOG randomly assigned 114 patients to radiation therapy (59.4 Gy) alone or with concurrent infusional 5-FU (1,000 mg/m² daily on days 2 through 5 and days 28 through 31) plus mitomycin (10 mg/m² on day 2) and found no difference in OS between the two groups.[3]

Whether chemoradiation therapy should be considered for patients with stage III pancreatic cancer is controversial. Preliminary results from a study of the FFCD-SFRO were presented in abstract form at the 2006 American Society of Clinical Oncology meeting.[4] Patients with locally advanced pancreatic cancer were randomly assigned to receive either concurrent chemoradiation therapy followed by gemcitabine or gemcitabine alone. The trial was halted because of poor accrual after 109 of the planned 176 patients were enrolled. In a preliminary report with a median 16-month follow-up, patients who received chemoradiation followed by gemcitabine had a median survival of 8.4 months versus 14.3 months for the group who received gemcitabine alone (stratified log-rank, P = .014).

Standard treatment options:

1. Palliative surgical biliary and/or gastric bypass, percutaneous radiologic biliary stent placement, or endoscopic biliary stent placement.[6,7]



2. Chemotherapy with gemcitabine.

Treatment options under clinical evaluation:

1. For patients with technically unresectable tumors, clinical trials evaluating novel agents in combination with chemotherapy or chemoradiation therapy (RTOG-PA-0020 ¹⁷ is one example).



2. Intraoperative radiation therapy and/or implantation of radioactive sources.[8,9]

Stage IV Pancreatic Cancer

Note: Some citations in the text of this section are followed by a level of evidence. The PDQ editorial boards use a formal ranking system to help the reader judge the strength of evidence linked to the reported results of a therapeutic strategy. (Refer to the PDQ summary on Levels of Evidence ² for more information.)

The low objective response rate and lack of survival benefit with current chemotherapy indicates clinical trials as appropriate treatment of all newly diagnosed patients. Occasional patients have palliation of symptoms when treated by chemotherapy with well-tested older drugs such as fluorouracil (5-FU). Gemcitabine has demonstrated activity in patients with pancreatic cancer and is a useful palliative agent.[1-3] A phase III trial of gemcitabine versus 5-FU as first-line therapy in patients with advanced or metastatic adenocarcinoma of the pancreas reported a significant improvement in survival among patients treated with gemcitabine (1-year survival was 18% with gemcitabine as compared with 2% with 5-FU, P = .003).[2][Level of evidence: 1iiA] A preliminary report, in abstract form, of a phase III trial (CAN-NCIC-PA3 ¹⁹) comparing gemcitabine alone versus the combination of gemcitabine and erlotinib (100 mg/day) in patients with advanced or metastatic pancreatic carcinomas showed that erlotinib modestly prolonged survival when combined with gemcitabine alone.[4] Differences in overall survival (OS) favored the erlotinib arm (hazard ratio = 0.81; 95% confidence interval, 0.67–0.97; P = .025). The corresponding median and 1-year survival rates for patients receiving erlotinib versus placebo were 6.37 months and 5.91 months, and 24% versus 17%, respectively.[4][Level of evidence: 1iiA] When 5-FU was added to gemcitabine and compared with gemcitabine alone, the median survival of patients with advanced or metastatic disease (6.7 months vs. 5.7 months, respectively, P = .09) was not significantly improved.[5][Level of evidence: 1iiA]

Standard treatment options:

1. Chemotherapy with gemcitabine or gemcitabine and erlotinib.[1,6-14]



2. Pain-relieving procedures (e.g., celiac or intrapleural block) and supportive care.[15]



3. Palliative surgical biliary bypass, percutaneous radiologic biliary stent placement, or endoscopically placed biliary stents.[16-18]

Treatment options under clinical evaluation:

• Clinical trials evaluating new anticancer agents alone or in combination with chemotherapy.[6-11,13,19-24]

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with stage IV pancreatic cancer ²⁰. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

Recurrent Pancreatic Cancer

Chemotherapy occasionally produces objective antitumor response, but the low percentage of significant responses and lack of survival advantage warrant use of therapies under evaluation.[1]

Standard treatment options:

1. Chemotherapy with fluorouracil [2] or gemcitabine.[3-5]



2. Palliative surgical bypass procedures, such as endoscopic or radiologically placed stents.[6,7]



3. Palliative radiation procedures.



4. Pain relief by celiac axis nerve or intrapleural block (percutaneous).[8]



5. Other palliative medical care alone.

Treatment options under clinical evaluation:

• Clinical trials evaluating pharmacologic modulation of fluorinated pyrimidines, new anticancer agents, or biologicals (phase I and II).

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with recurrent pancreatic cancer ²¹. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site ⁶.
