Cellular Classification of Esophageal Cancer

Adenocarcinomas, typically arising in Barrett esophagus, account for at least 50% of malignant lesions, and the incidence of this histology appears to be rising. Barrett esophagus contains glandular epithelium cephalad to the esophagogastric junction.

Three different types of glandular epithelium can be seen:

Metaplastic columnar epithelium.

Metaplastic parietal cell glandular epithelium within the esophageal wall.

Metaplastic intestinal epithelium with typical goblet cells. Dysplasia is particularly likely to develop in the intestinal type mucosa.

Fewer than 50% of esophageal cancers are squamous cell carcinomas.

Gastrointestinal stromal tumors can occur in the esophagus and are usually benign. (Refer to the PDQ summary on Gastrointestinal Stromal Tumors Treatment (Adult) for more information.)

Stage Information for Esophageal Cancer

One of the major difficulties in allocating and comparing treatment modalities for patients with esophageal cancer is the lack of precise preoperative staging. The stage determines whether the intent of the therapeutic approach will be curative or palliative.

Staging Evaluation

Standard noninvasive staging modalities include the following:

Endoscopic ultrasound.

Computed tomography (CT) scan of the chest and abdomen.

Positron emission tomography (PET)-CT scan.

The overall tumor depth staging accuracy of endoscopic ultrasound is 85% to 90%, compared with 50% to 80% for CT; the accuracy of regional nodal staging is 70% to 80% for endoscopic ultrasound and 50% to 70% for CT.

One retrospective series reported 93% sensitivity and 100% specificity of regional nodal staging with endoscopic ultrasound-guided fine-needle aspiration (FNA). Endoscopic ultrasound-guided FNA for lymph node staging is under prospective evaluation.

Thoracoscopy and laparoscopy have been used in esophageal cancer staging at some surgical centers.

An intergroup trial reported an increase in positive lymph node detection to 56% of 107 evaluable patients with the use of thoracoscopy/laparoscopy, from 41% (with the use of noninvasive staging tests, e.g., CT, magnetic resonance imaging, and endoscopic ultrasound), with no major complications or deaths.

Noninvasive PET scan using the radiolabeled glucose analog fluorine F 18-fludeoxyglucose (18F-FDG) for preoperative staging of esophageal cancer is more sensitive than a CT scan or endoscopic ultrasound in detection of distant metastases. A recent study of 262 patients with potentially resectable esophageal cancer demonstrated the utility of 18F-FDG PET in identifying confirmed distant metastatic disease in at least 4.8% of patients after standard evaluation.

AJCC Staging System

The AJCC has designated staging by TNM (tumor, node, metastasis) classification to define cancer of the esophagus and esophagogastric junction.

Tumors located in the gastric cardia within 5 cm of the gastroesophageal junction with extension into the esophagus or the gastroesophageal junction are classified as esophageal cancer. Tumors with the epicenter of the tumor located in the gastric cardia beyond 5 cm of the gastroesophageal junction or without extension into the esophagus are classified as gastric cancer.

(Refer to the Stage Information for Gastric Cancer section in the PDQ summary on Gastric Cancer Treatment for more information.)

The classification of involved abdominal lymph nodes as M1 disease is controversial. The presence of positive abdominal lymph nodes does not appear to have a prognosis as grave as that for metastases to distant organs.

Patients with regional and/or celiac axis lymphadenopathy should not necessarily be considered to have unresectable disease caused by metastases. Complete resection of the primary tumor and appropriate lymphadenectomy is attempted when possible.

Treatment Option Overview for Esophageal Cancer

For patients with minimally invasive resectable esophageal cancer, surgical resection alone offers the potential for cure. In contrast, therapeutic management for patients with locally advanced resectable esophageal cancer has evolved significantly over the last few decades. Because of the risk of distant metastases and local relapse, multimodality therapy with integration of chemotherapy, radiation therapy, and surgical resection has become the standard of care.

Combined modality therapies are under clinical evaluation and include the following:

Surgery alone.

Chemotherapy.

Radiation therapy.

Effective palliation may be obtained in individual cases with various combinations of the following:

Surgery.

Chemotherapy.

Radiation therapy.

Stents.

Photodynamic therapy.

Endoscopic therapy with Nd:YAG laser.

Surgery

Surgery (Barrett esophagus)

The prevalence of Barrett metaplasia in adenocarcinoma of the esophagus suggests that Barrett esophagus is a premalignant condition. Endoscopic surveillance of patients with Barrett metaplasia may detect adenocarcinoma at an earlier stage that is more amenable to curative resection. Strong consideration should be given to resection in patients with high-grade dysplasia in the setting of Barrett metaplasia.

Surgery (esophageal cancer)

The survival rate of patients with esophageal cancer is poor. Surgical treatment of resectable esophageal cancers results in 5-year survival rates of 5% to 30%, with higher survival rates in patients with early-stage cancers.

Asymptomatic small tumors confined to the esophageal mucosa or submucosa are detected only by chance. Surgery is the treatment of choice for these small tumors. Once symptoms are present (e.g., dysphagia, in most cases), esophageal cancers have usually invaded the muscularis propria or beyond and may have metastasized to lymph nodes or other organs.

In some patients with partial esophageal obstruction, dysphagia may be relieved by placement of an expandable metallic stent

or by radiation therapy if the patient has disseminated disease or is not a candidate for surgery. Alternative methods of relieving dysphagia have been reported, including laser therapy and electrocoagulation to destroy intraluminal tumor.

In the presence of complete esophageal obstruction without clinical evidence of systemic metastasis, surgical excision of the tumor with mobilization of the stomach to replace the esophagus has been the traditional means of relieving the dysphagia.

The optimal surgical approach for radical resection of esophageal cancer is not known. One approach advocates transhiatal esophagectomy with anastomosis of the stomach to the cervical esophagus. A second approach advocates abdominal mobilization of the stomach and transthoracic excision of the esophagus with anastomosis of the stomach to the upper thoracic esophagus or the cervical esophagus. One study concluded that transhiatal esophagectomy was associated with lower morbidity than was transthoracic esophagectomy with extended en bloc lymphadenectomy; however, median overall disease-free and quality-adjusted survival did not differ significantly.

Similarly, no differences in long-term quality of life (QOL) using validated QOL instruments have been reported.

More recently, minimally invasive approaches that offer potential advantages of smaller incisions, decreased intraoperative blood loss, fewer postoperative complications, and shorter hospital stays have emerged. However, the ability to obtain negative surgical margins, the adequacy of lymph node dissection, and long-term outcomes have not been fully established with this approach.

In the United States, the median age of patients who present with esophageal cancer is 67 years.

The results of a retrospective review of 505 consecutive patients who were operated on by a single surgical team over 17 years found no difference in the perioperative mortality, median survival, or palliative benefit of esophagectomy on dysphagia when the patients older than 70 years were compared with their younger peers.

[Levels of evidence: 3iiA and 3iiB] All of the patients in this series were selected for surgery on the basis of potential operative risk. Age alone does not determine therapy for patients with potentially resectable disease.

Surgical treatment of esophageal cancer is associated with an operative mortality rate of less than 10%.

In an attempt to avoid perioperative mortality and to relieve dysphagia, definitive radiation therapy in combination with chemotherapy has been studied.

Preoperative Chemoradiation Therapy

On the basis of several randomized trial results, chemoradiation followed by surgery is a standard treatment option for patients with stages IB, II, III, and IVA esophageal cancer.

Phase III trials have compared preoperative concurrent chemoradiation therapy with surgery alone for patients with esophageal cancer.

[Level of evidence: 1iiA] The benefit of neoadjuvant chemoradiation has been controversial because of contradictory results of early randomized studies.

However, the Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study (CROSS) has definitively demonstrated a survival benefit for preoperative chemoradiation compared with surgery alone in locally advanced esophageal cancer.

For early-stage tumors, the role of preoperative chemoradiation remains controversial. Although the CROSS study included early-stage patients, the Francophone de Cancérologie Digestive (FFCD) 9901 study (NCT00047112)

, which included only early-stage (stage I or II) patients, failed to demonstrate a survival advantage in this group of patients.

Evidence (preoperative chemoradiation therapy):

The CROSS study randomly assigned 366 patients with resectable esophageal or junctional cancers to receive either surgery alone or weekly administration of carboplatin (dose titrated to achieve an AUC [area under the curve] of 2 mg/mL/minute) and paclitaxel (50 mg/m2 of BSA [body surface area]) and concurrent radiation therapy (41.4 Gy in 23 fractions) administered over 5 weeks. Most patients enrolled in the CROSS trial (75%) had adenocarcinoma.

[Level of evidence: 1iiA]

With a median follow-up of 84 months, preoperative chemoradiation was found to improve median overall survival (OS) from 24 months in the surgery-alone group to 48.6 months (hazard ratio [HR], 0.68; 95% confidence interval [CI], 0.53–0.88; P = .003). Median OS for patients with squamous cell carcinomas was 81.6 months in the preoperative chemoradiation group compared with 21.1 months in the surgery-alone group (HR, 0.48; 95% CI, 0.28–0.83; log rank P = .008); for patients with adenocarcinomas, median OS was 43.2 months in the preoperative chemoradiation group compared with 27.1 months in the surgery-alone group (HR, 0.73; 95% CI, 0.55–0.98; log rank P = .038).

Additionally, preoperative chemoradiation improved the rate of R0 resections (92% vs. 69%, P < .001). R0 is defined as complete resection with no tumor within 1 mm of resection margins.

A complete pathologic response was achieved in 29% of patients who underwent resection after chemoradiation therapy. A pathologic complete response was observed in 23% of patients with adenocarcinoma compared with 49% of patients with squamous cell carcinoma (P = .008).

Postoperative complications and in-hospital mortality were equivalent in both groups. The most common hematologic side effects in the chemoradiation group were leukopenia (6%) and neutropenia (2%). The most common nonhematologic side effects were anorexia (5%) and fatigue (3%).

With a median follow-up of 84 months, the 5-year progression-free survival (PFS) was 44% in the preoperative chemoradiation group compared with 27% in the surgery-alone group (HR, 0.61 [0.47–0.78]). Preoperative chemoradiation therapy reduced locoregional recurrence from 34% to 14% (P < .001) and peritoneal carcinomatosis from 14% to 4% (P < .001). There was a small but significant effect on hematogenous dissemination in favor of the chemoradiation therapy group (35% vs. 29%; P = .025).

[Level of evidence: 1iiDii]

A multicenter prospective randomized trial compared preoperative combined chemotherapy (i.e., cisplatin) and radiation therapy (37 Gy in 3.7-Gy fractions) versus surgery alone in patients with squamous cell carcinoma.

[Level of evidence: 1iiA]

The study showed no improvement in OS and a significantly higher postoperative mortality (12% vs. 4%) in the combined-modality arm.

In patients with adenocarcinoma of the esophagus, a single-institution phase III trial was conducted in patients treated with induction chemoradiation therapy consisting of 5-fluorouracil (5-FU), cisplatin, and 40 Gy (in 2.67-Gy fractions) plus surgery compared with resection alone.

[Level of evidence: 1iiA]

The results demonstrated a modest survival benefit of 16 months for combined modality therapy versus 11 months for surgery alone.

A subsequent single-institution trial randomly assigned patients (75% with adenocarcinoma) to 5-FU, cisplatin, vinblastine, and radiation therapy (1.5 Gy twice daily to a total of 45 Gy) plus resection versus esophagectomy alone.

[Level of evidence: 1iiA]

At a median follow-up of more than 8 years, there was no significant difference between the surgery alone and combined modality therapy with respect to median survival (17.6 months vs. 16.9 months), OS (16% vs. 30% at 3 years), or disease-free survival (16% vs. 28% at 3 years).

An intergroup trial (CALGB-9781 [NCT00003118]) planned to randomly assign 475 patients with resectable squamous cell or adenocarcinoma of the thoracic esophagus to treatment with preoperative chemoradiation therapy (5-FU, cisplatin, and 50.4 Gy) followed by esophagectomy and nodal dissection or surgery alone. The trial was closed as a result of poor patient accrual; however, results from the 56 enrolled patients, with a median follow-up of 6 years, were reported.

[Level of evidence: 1iiA]

The median survival was 4.48 years (95% CI; range, 2.4 years to not estimable) for trimodality therapy versus 1.79 years (95% CI, 1.41–2.59 years) for surgery alone (P = .002), with 5-year OS of 39% for trimodality therapy (95% CI, 21%–57%) versus 16% for surgery alone (95% CI, 5%–33%).

To further evaluate the impact of neoadjuvant chemoradiation therapy for early-stage disease, FFCD 9901 randomly assigned 195 patients with stage I or stage II esophageal cancer to receive surgery alone or neoadjuvant chemoradiation therapy (45 Gy in 25 fractions administered with two courses of 5-FU [800 mg/m2] and cisplatin [75 mg/m2]) followed by surgery.

[Level of evidence: 1iiA]

At interim analysis, accrual to the study was stopped early because of futility.

With a median follow-up of 94 months, there was no significant improvement in 3-year OS with chemoradiation (48% vs. 53%, P = .94); there was a significantly higher postoperative mortality rate of 11.1% versus 3.4% (P = .049).

Preoperative Chemotherapy

The effects of preoperative chemotherapy are being evaluated in randomized trials. Several studies have demonstrated a survival benefit with preoperative chemotherapy compared with surgery alone.

However, one large randomized study failed to confirm a survival benefit with preoperative chemotherapy.

Compared with preoperative chemotherapy alone, preoperative chemoradiation therapy improves pathologic response and may improve outcomes.

Evidence (preoperative chemotherapy):

An intergroup trial (NCT00525785) randomly assigned 440 patients with local and operable esophageal cancer of any cell type to three cycles of preoperative 5-FU and cisplatin followed by surgery and two additional cycles of chemotherapy versus surgery alone.

[Level of evidence: 1iiA]

After a median follow-up of 55 months, there were no significant differences in median survival between the chemotherapy-plus-surgery group (14.9 months) and the surgery-alone group (16.1 months); median survival at 2 years was 35% for the chemotherapy-plus-surgery group and 37% for the surgery-alone group.

The addition of chemotherapy did not increase the morbidity associated with surgery.

The Medical Research Council Oesophageal Cancer Working Party randomly assigned 802 patients with resectable esophageal cancer, also of any cell type, to two cycles of preoperative 5-FU and cisplatin followed by surgery versus surgery alone.

[Level of evidence: 1iiA]

At a median follow-up of 37 months, median survival was significantly improved in the preoperative chemotherapy arm (16.8 months vs. 13.3 months with surgery alone; difference, 3.5 months; 95% CI, 1.0–6.5 months), as was 2-year OS (43% in the preoperative chemotherapy arm and 34% in the surgery-alone arm; difference, 9%; 95% CI, 3–14 months).

The interpretation of the results from the intergroup and preoperative chemotherapy trials is challenging because T or N staging was not reported, and prerandomization and radiation could be offered at the discretion of the treating oncologist.

The Japanese Clinical Oncology Group randomly assigned 330 patients with clinical stage II or III, excluding T4, squamous cell carcinomas to receive either two cycles of preoperative cisplatin and 5-FU followed by surgery or surgery followed by postoperative chemotherapy of the same regimen. A planned interim analysis was conducted after patient accrual; although the primary endpoint of PFS was not met, there was a significant benefit in OS among patients treated with preoperative chemotherapy (P = .01). As a result of these findings, the Data and Safety Monitoring Committee recommended early closure of the study.

[Level of evidence: 1iiC]

With a median follow-up of 61 months, the 5-year OS was 55% among patients treated with preoperative chemotherapy compared with 43% among patients treated with postoperative chemotherapy (P = .04). However, there was no significant difference between groups with respect to PFS (5-year PFS, 39% vs. 44%; P = .22).

Additionally, there were no significant differences between the two groups with respect to postoperative complications or treatment-related toxicities.

The Fédération Nationale des Centres de Lutte contre le Cancer and the FFCD randomly assigned 224 patients with resectable adenocarcinoma of the lower esophagus, gastroesophageal junction, or stomach to receive either perioperative chemotherapy and surgery (n = 113) or surgery alone (n = 111). Chemotherapy consisted of two or three preoperative cycles of intravenous (IV) cisplatin (100 mg/m2) on day 1 and continuous IV infusion of 5-FU (800 mg/m2) for 5 consecutive days (day 1–5) every 28 days, and three or four postoperative cycles of the same regimen.

[Level of evidence: 1iiA]

Perioperative chemotherapy was associated with improved 5-year OS (5–year OS, 38% vs. 24%; HR, 0.69; P = .02).

Grade 3 and 4 toxicity occurred in 38% of patients treated with perioperative chemotherapy, but there was no increase in postoperative morbidity.

The Preoperative Chemotherapy or Radiochemotherapy in Esophago-gastric Adenocarcinoma Trial (POET) sought to evaluate the additional benefit of radiation therapy to preoperative chemotherapy. Patients were randomly assigned to receive either induction chemotherapy (15 weeks) followed by surgery or chemotherapy (12 weeks) followed by chemoradiation therapy (3 weeks) followed by surgery.

[Level of evidence: 1iiA]

The study was closed early because of poor accrual. In total, 126 patients were randomly assigned.

Preoperative radiation therapy yielded 3-year survival of 27% to 47% (log rank, P = .07). Postoperative mortality was nonsignificantly increased in the chemoradiation therapy group (10.2% vs. 3.8%, P = .26).

Definitive Chemoradiation

For patients who are deemed either medically inoperable or have tumors that are unresectable, the efficacy of definitive chemoradiation has been established in numerous randomized controlled trials.

For patients with squamous cell carcinomas of the esophagus, definitive chemoradiation may offer equivalent outcomes compared with preoperative chemoradiation followed by surgical resection.

Evidence (definitive chemoradiation):

A Radiation Therapy Oncology Group trial (RTOG-8501) randomly assigned patients to chemotherapy and radiation therapy versus radiation therapy alone. Patients were randomly assigned to receive radiation therapy alone (64 Gy in 32 fractions) or chemoradiation (50 Gy in 25 fractions) with concurrent cisplatin (75 mg/m2) and continuous-infusion 5-FU (1,000 mg/m2 on days 1 to 4 in weeks 1 and 5 followed by two additional cycles of chemotherapy administered 3 weeks apart).

[Level of evidence: 1iiA]

There was an improvement in 5-year survival for the combined modality group (27% vs. 0%).

An 8-year follow-up of this trial demonstrated an OS rate of 22% for patients receiving chemoradiation therapy.

Intergroup-0123 (RTOG-9405 [NCT00002631]) was conducted in an attempt to improve upon the results of RTOG-8501. Intergroup-0123 randomly assigned 236 patients with localized esophageal tumors to undergo chemoradiation with high-dose radiation therapy (64.8 Gy) and four monthly cycles of 5-FU and cisplatin versus conventional-dose radiation therapy (50.4 Gy) and the same chemotherapy schedule.

[Level of evidence: 1iiA]

Although originally designed to accrue 298 patients, this trial was closed in 1999 after a planned interim analysis showed that it was statistically unlikely that there would be any advantage to using high-dose radiation.

At a 2-year median follow-up, no statistically significant differences in median survival were observed between the high-dose and conventional-dose radiation therapy arms (13 months vs. 18 months), 2-year survival (31% vs. 40%), or local and regional failures (56% vs. 52%).

There was a higher treatment mortality in the higher-dose arm (9% vs. 2%); however, 7 of 11 deaths in the high-dose arm occurred in patients who had received 50.4 Gy or less.

An Eastern Cooperative Oncology Group trial (EST-1282) evaluated 135 patients.

[Level of evidence: 1iiA]

This trial showed that chemotherapy plus radiation therapy provided a better 2-year survival rate than did radiation therapy alone, similar to results from the intergroup trial.

The PRODIGE5/ACCORD17 (NCT00861094) trial sought to evaluate and compare the efficacy and safety of oxaliplatin, fluorouracil, and leucovorin calcium (FOLFOX) versus 5-FU and cisplatin as the chemotherapy backbone among patients treated with definitive chemoradiation for localized esophageal cancer. In this multicenter, randomized, phase II and III trial, 267 patients were randomly assigned to receive either six cycles of FOLFOX (three cycles concomitant with radiation therapy), oxaliplatin (85 mg/m2), leucovorin (200 mg/m2), bolus 5-FU (400 mg/m2) and infusion 5-FU (1,600 mg/m2 over 46 hours) or four cycles of 5-FU (1,000 mg/m2 for 4 days) and cisplatin (75 mg/m2 on day 1). All patients received radiation therapy (50 Gy in 25 fractions).

[Level of evidence: 1iiDiii]

With a median follow-up of 25.3 months, there was no significant difference in PFS (9.7 months with FOLFOX vs. 9.4 months with 5-FU and cisplatin; P = .64).

There was one death caused by toxicity in the FOLFOX group versus six deaths in the 5-FU and cisplatin arm (P = .066).

There were no significant differences in grade 3 or 4 adverse events between treatment groups. Among toxicities of all grades, paresthesia, sensory neuropathy, and increases in aspartate transaminase and alanine transaminase were more common in the FOLFOX group; whereas, increases in serum creatinine, mucositis, and alopecia were more common in the 5-FU and cisplatin group.

A phase III German trial also compared induction chemotherapy (three courses of bolus 5-FU, leucovorin, etoposide, and cisplatin) followed by chemoradiation therapy (cisplatin, etoposide, and 40 Gy) followed by surgery (arm A), or the same induction chemotherapy followed by chemoradiation therapy (at least 65 Gy) without surgery (arm B) for patients with T3 or T4 squamous cell carcinoma of the esophagus. OS was the primary outcome.

[Level of evidence: 1iiA]

The analysis of 172 eligible, randomly assigned patients showed that OS at 2 years was not statistically significantly different between the two treatment groups (arm A, 39.9%; 95% CI, 29.4%–50.4%; arm B, 35.4%; 95% CI, 25.2%–45.6%; log-rank test for equivalence with 0.15, P < .007).

Local PFS was higher in the surgery group (2-year PFS, 64.3%; 95% CI, 52.1%–76.5%) than in the chemoradiation therapy group (2-year PFS, 40.7%; 95% CI, 28.9%–52.5%; HR for arm B vs. arm A, 2.1; 95% CI, 1.3–3.5; P < .003).

Treatment-related mortality was higher in the surgery group (12.8%) than in the chemoradiation therapy group (3.5%) (P < .03).

FFCD 9102 (NCT00416858) randomly assigned 259 patients with T3N0–1M0 thoracic esophageal cancer to receive either two cycles of 5-FU and cisplatin (days 1–5 and 22–26) and either conventional radiation therapy (46 Gy in 4.5 weeks) or split course (15 Gy, days 1–5 and 22–26). Patients with response were then randomly assigned to receive either surgical resection (arm A) or continuation of chemoradiation (arm B: three cycles of 5-FU plus cisplatin and either conventional 20 Gy or split-course 15 Gy radiation therapy).

[Level of evidence: 1iiA]

Of the 259 randomly assigned patients, 230 (89%) had squamous cell carcinoma, and 29 patients (11%) had adenocarcinomas.

The 2-year OS was 34% in patients randomly assigned to receive surgery versus 40% in patients randomly assigned to receive definitive chemoradiation (HR, 0.90; P = .44). Median survival was 17.7 months for surgery and 19.3 months for definitive chemoradiation.

The 3-month mortality rate was 9.3% in the surgery arm compared with 0.8% in the chemoradiation arm (P = .002).

Postoperative Radiation Therapy

Two randomized trials have shown no significant OS benefit for postoperative radiation therapy compared with surgery alone.

[Level of evidence: 1iiA] All newly diagnosed patients should be considered candidates for therapies and clinical trials comparing various treatment modalities. Information about ongoing clinical trials is available from the NCI website.

Treatment options for stage IV esophageal cancer include the following:

Chemoradiation followed by surgery (for patients with stage IVA disease).

Chemotherapy, which has provided partial responses for patients with metastatic distal esophageal adenocarcinomas.

Nd:YAG endoluminal tumor destruction or electrocoagulation.

Endoscopic-placed stents to provide palliation of dysphagia.

Radiation therapy with or without intraluminal intubation and dilation.

Intraluminal brachytherapy to provide palliation of dysphagia.

Esophageal cancer responds to many anticancer agents. Objective response rates of 30% to 60% and median survivals of less than 1 year are commonly reported with platinum-based combination regimens with 5-fluorouracil, taxanes, topoisomerase inhibitors, hydroxyurea, or vinorelbine.

Trastuzumab may be effective in combination with chemotherapy among patients with tumors that overexpress HER2-neu.

[Level of evidence: 1iiA]

Clinical trials evaluating single-agent or combination chemotherapy.

About This PDQ Summary

Purpose of This Summary

This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about treatment of adult esophageal cancer. It 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.

Reviewers and Updates

This summary is reviewed regularly and updated as necessary by the PDQ Adult Treatment Editorial Board, which is editorially independent of the National Cancer Institute (NCI). The summary reflects an independent review of the literature and does not represent a policy statement of NCI or the National Institutes of Health (NIH).

Board members review recently published articles each month to determine whether an article should:

be discussed at a meeting,

be cited with text, or

replace or update an existing article that is already cited.

Changes to the summaries are made through a consensus process in which Board members evaluate the strength of the evidence in the published articles and determine how the article should be included in the summary.

Any comments or questions about the summary content should be submitted to Cancer.gov through the NCI website's Email Us. Do not contact the individual Board Members with questions or comments about the summaries. Board members will not respond to individual inquiries.

Levels of Evidence

Some of the reference citations in this 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 in developing its level-of-evidence designations.
