Incidence and Mortality

Estimated new cases and deaths from esophageal cancer in the United States in 2024:[1]

• New cases: 22,370.
• Deaths: 16,130.

The incidence of esophageal cancer has risen in recent decades, coinciding with a shift in histological type and primary tumor location. Worldwide, squamous cell carcinoma is the predominant histology, and was historically more prevalent in the United States. However, the incidence of adenocarcinoma has risen dramatically in the last few decades and is now more prevalent than squamous cell carcinoma in the United States and western Europe.[2-4] The incidence of adenocarcinoma has increased most notably among White men.[5] In the United States, the median age of patients who present with esophageal cancer is 68 years.[6] Most adenocarcinomas are located in the distal esophagus. The cause of the rising incidence and demographic alterations is unknown.

Anatomy

The esophagus and stomach are part of the upper gastrointestinal (digestive) system.

The esophagus serves as a conduit to the gastrointestinal tract for food. The esophagus extends from the larynx to the stomach and lies in the posterior mediastinum within the thorax near the lung pleura, peritoneum, pericardium, and diaphragm. As it travels into the abdominal cavity, the esophagus makes an abrupt turn and enters the stomach. The most muscular segment of the gastrointestinal system, the esophagus is composed of inner circular and outer longitudinal muscle layers. The upper and lower esophagus are controlled by the sphincter function of the cricopharyngeus muscle and gastroesophageal sphincter, respectively. The esophagus has a rich network of lymphatic channels concentrated in the lamina propria and submucosa, which drains longitudinally along the submucosa.

Tumors of the esophagus are conventionally described in terms of distance of the upper border of the tumor to the incisors. When measured from the incisors via endoscopy, the esophagus extends approximately 30 cm to 40 cm. The esophagus is divided into four main segments:

1. Cervical esophagus (~15–20 cm from the incisors).
2. Upper thoracic esophagus (~20–25 cm from the incisors).
3. Middle thoracic esophagus (~25–30 cm from the incisors).
4. Lower thoracic esophagus and gastroesophageal junction (~30–40 cm from the incisors).

Risk Factors

Risk factors for squamous cell carcinoma of the esophagus include the following:

• Tobacco use.
• Alcohol use.

Risk factors associated with esophageal adenocarcinoma are less clear.[3] Barrett esophagus is an exception, and its presence is associated with an increased risk of developing adenocarcinoma of the esophagus. Chronic reflux is considered the predominant cause of Barrett metaplasia. The results of a population-based, case-controlled study from Sweden strongly suggest that symptomatic gastroesophageal reflux is a risk factor for esophageal adenocarcinoma. The frequency, severity, and duration of reflux symptoms were positively correlated with increased risk of esophageal adenocarcinoma.[7] For more information, see Esophageal Cancer Prevention.

Prognostic Factors

Favorable prognostic factors include the following:

• Early-stage disease.
• Complete resection.

Patients with severe dysplasia in distal esophageal Barrett mucosa often have in situ or invasive cancer within the dysplastic area. After resection, these patients usually have excellent prognoses.[8]

In most cases, esophageal cancer is a treatable disease, but it is rarely curable. The 5-year relative survival rate is 21.6%. Patients with early-stage disease have a better chance of survival; 18.2% of patients are diagnosed at the local stage and have a 5-year relative survival rate of 48.1%.[6]

Staging Evaluation

Standard noninvasive staging modalities include the following:

• Endoscopic ultrasonography.
• Computed tomography (CT) scan of the chest and abdomen.
• Positron emission tomography (PET)–CT scan.

The overall tumor depth staging accuracy of endoscopic ultrasonography is 85% to 90%, compared with 50% to 80% for CT. The accuracy of regional nodal staging is 70% to 80% for endoscopic ultrasonography and 50% to 70% for CT.[1,2]

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.[3]

Thoracoscopy and laparoscopy have been used in esophageal cancer staging at some surgical centers.[4-6] 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.[7]

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.[8-12]

AJCC Staging System

The AJCC has designated staging by TNM (tumor, node, metastasis) classification to define cancer of the esophagus and esophagogastric junction.[13] 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.[13] For more information, see the Stage Information for Gastric Cancer section in Gastric Cancer Treatment.

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.[14] 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.

Preoperative Chemoradiation Therapy

On the basis of several randomized trial results, chemoradiation followed by surgery is a 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.[19-25][Level of evidence A1] The benefit of neoadjuvant chemoradiation has been controversial because of contradictory results of early randomized studies.[19-22] 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.[23]

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),[25] 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):

1. 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.[23,26][Level of evidence A1]

   • With a median follow-up of 84 months, preoperative chemoradiation was found to improve median OS from 24 months in the surgery-alone group to 48.6 months (HR, 0.68; 95% 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).[26]
   • 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 pathological response was achieved in 29% of patients who underwent resection after chemoradiation therapy. A pathological 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) rate was 44% in the preoperative chemoradiation group, compared with 27% in the surgery-alone group (HR, 0.61; 95% CI, 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).[24,26][Level of evidence B1]
2. 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.[19][Level of evidence A1]

   • The study showed no improvement in OS and a significantly higher postoperative mortality rate (12% vs. 4%) in the combined-modality arm.
3. 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-FU, cisplatin, and 40 Gy (in 2.67-Gy fractions) plus surgery compared with resection alone.[20][Level of evidence A1]

   • The results demonstrated a modest survival benefit of 16 months for combined modality therapy versus 11 months for surgery alone.
4. 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.[21][Level of evidence A1]

   • 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 rate (16% vs. 30% at 3 years), or DFS rate (16% vs. 28% at 3 years).
5. 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.[22][Level of evidence A1]

   • The median survival was 4.48 years (95% CI; range, 2.4–not estimable) for trimodality therapy versus 1.79 years (95% CI, 1.41–2.59) for surgery alone (P = .002), with a 5-year OS rate of 39% for trimodality therapy (95% CI, 21%–57%) versus 16% for surgery alone (95% CI, 5%–33%).
6. To further evaluate the impact of neoadjuvant chemoradiation therapy for early-stage disease, the FFCD 9901 study 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.[25][Level of evidence A1]

   • 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 rates with chemoradiation (48% vs. 53%; P = .94); there was a significantly higher postoperative mortality rate of 11.1% versus 3.4% (P = .049).
7. The NRG Oncology/RTOG-1010 trial (NCT01196390) evaluated the addition of trastuzumab to trimodality treatment (paclitaxel plus carboplatin and radiotherapy, followed by surgery) in patients with untreated HER2-overexpressing esophageal adenocarcinoma. This phase III trial entered 606 patients for HER2 assessment. A total of 203 patients with HER2-positive disease were randomly assigned to receive chemoradiation therapy plus trastuzumab (n = 102) or chemoradiation therapy alone (n = 101). The primary end point was DFS. The median duration of follow-up was 2.8 years.[27]

   • The median DFS was 19.6 months (95% CI, 13.5–26.2) for patients who received chemoradiation therapy plus trastuzumab and 14.2 months (10.5–23.0) for patients who received chemoradiation therapy alone (HR, 0.99; 95% CI, 0.71–1.39; log-rank P = .97).[27][Level of evidence B1]
   • Grade 3 treatment-related adverse events occurred in 41 of 95 patients (43%) who received trastuzumab and 52 of 96 patients (54%) of patients who received chemoradiation therapy alone. Grade 4 treatment-related adverse events occurred in 20 patients (21%) who received trastuzumab and 21 patients (22%) who received chemoradiation therapy alone.
   • There were five treatment-related deaths in the trastuzumab group (bronchopleural fistula, esophageal anastomotic leak, lung infection, sudden death, and death not otherwise specified), and three deaths in the chemoradiation therapy group (two multiorgan failure and one sepsis).
   In conclusion, this trial confirmed that trastuzumab does not have a role in the preoperative treatment of HER2-positive esophageal or gastroesophageal cancer, either with chemotherapy alone or with chemoradiation therapy.

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.[28-30] However, one large randomized study failed to confirm a survival benefit with preoperative chemotherapy.[31] Compared with preoperative chemotherapy alone, preoperative chemoradiation therapy improves pathological response and may improve outcomes.[32]

Evidence (preoperative chemotherapy):

1. 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.[31][Level of evidence A1]

   • 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). The median 2-year survival rate was 35% in the chemotherapy-plus-surgery group and 37% in the surgery-alone group.
   • The addition of chemotherapy did not increase the morbidity associated with surgery.
2. 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.[28][Level of evidence A1]

   • 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; 95% CI), as was the 2-year OS rate (43% in the preoperative chemotherapy arm and 34% in the surgery-alone arm; 95% CI).
   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.
3. 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 end point 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.[29][Level of evidence A3]

   • With a median follow-up of 61 months, the 5-year OS rate 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 rate, 39% vs. 44%; P = .22).
   • Additionally, there were no significant differences between the two groups with respect to postoperative complications or treatment-related toxicities.
4. 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.[30][Level of evidence A1]

   • Perioperative chemotherapy was associated with an improved 5-year OS rate (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.
5. 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) and surgery.[32][Level of evidence A1]

   • The study was closed early because of poor accrual. In total, 126 patients were randomly assigned.
   • Preoperative radiation therapy yielded 3-year survival rates of 27% to 47% (log-rank P = .07). The postoperative mortality rate was nonsignificantly increased in the chemoradiation therapy group (10.2% vs. 3.8%; P = .26).

Perioperative Chemotherapy

1. A trial that included patients with resectable adenocarcinoma of the stomach, esophagogastric junction, or lower esophagus randomly assigned 250 patients to receive perioperative chemotherapy and surgery and 253 patients to receive surgery alone. Chemotherapy consisted of three preoperative and three postoperative cycles of IV epirubicin (50 mg/m²) and cisplatin (60 mg/m²) on day 1, and a continuous IV infusion of 5-FU (200 mg/m² per day) for 21 days. The primary end point was OS.[33]

   • After a median follow-up of 4 years, 149 patients in the perioperative chemotherapy group and 170 patients in the surgery-alone group had died.
   • Compared with the surgery-alone group, the perioperative chemotherapy group had a higher likelihood of OS (HR_death, 0.75; 95% CI, 0.60–0.93; P = .009). The 5-year survival rate was 36.3% in the perioperative chemotherapy group (95% CI, 29.5%–43.0%) and 23% (95% CI, 16.6%–29.4%) in the surgery-alone group.[33][Level of evidence A1]
   • The PFS rate was also improved in the perioperative chemotherapy group (HR_progression, 0.66; 95% CI, 0.53–0.81; P < .001) compared with the surgery-alone group.
   • The rate of postoperative complications was similar in the two groups; 46% in the perioperative chemotherapy group and 45% in the surgery-alone group. The number of deaths within 30 days after surgery was also similar between the two groups.
2. An open-label, randomized, phase II/III trial compared the efficacy and safety of the docetaxel-based triplet FLOT regimen with the combination of epirubicin and cisplatin plus either 5-FU given as a continuous infusion or capecitabine given orally. The trial included 716 patients with adenocarcinoma in clinical stage cT2 or higher, node-positive stage (cN+), or both, or resectable tumors with no evidence of distant metastases. Patients were randomly assigned to receive either: (1) ECF/ECX (three preoperative and three postoperative 3-week cycles of epirubicin [50 mg/m²] and cisplatin [60 mg/m²] on day 1 plus either 5-FU [200 mg/m²] given as a continuous infusion or capecitabine [1,250 mg/m²] orally on days 1 to 21), or (2) FLOT (four preoperative and four postoperative 2-week cycles of docetaxel [50 mg/m²], oxaliplatin [85 mg/m²], leucovorin [200 mg/m²], and 5-FU [2,600 mg/m²] as a 24-hour infusion on day 1). The primary end point of the trial was OS (superiority) in the intention-to-treat population.[34]

   • OS was longer in the FLOT group than the ECF/ECX group (HR, 0.77; 95% CI, 0.63–0.94). The median OS was 50 months in the FLOT group (38.33–not reached) and 35 months in the ECF/ECX group (27.35–46.26).[34][Level of evidence A1]
   • The number of patients with related serious adverse events (including those occurring during a hospital stay for surgery) was similar between the two groups: 96 patients (27%) in the ECF/ECX group and 97 patients (27%) in the FLOT group.
   • The number of deaths due to toxicity (two [<1%]) was similar in both groups. Hospitalization for toxicity occurred in 94 patients (26%) in the ECF/ECX group and 89 patients (25%) in the FLOT group.
3. The ESOPEC trial (NCT02509286), reported in abstract form, compared perioperative FLOT and surgery with neoadjuvant chemoradiation therapy with the CROSS regimen (41.4 Gy plus carboplatin and docetaxel) followed by surgery. The trial enrolled 438 patients with clinical (c)T1, cN+, cM0 or cT2–4a, any cN, cM0 resectable esophageal adenocarcinoma. The primary end point was OS.[35]

   • After a median follow-up of 55 months, 218 patients had died: 97 patients in the FLOT group and 121 patients in the CROSS group. The median OS was 66 months (95% CI, 36–not estimable) for patients in the FLOT group and 37 months (95% CI, 28–43) for patients in the CROSS group.
   • The 3-year OS rates were 57.4% (95% CI, 50.1%–64.0%) for patients in the FLOT group and 50.7% (95% CI, 43.5%–57.5%) for patients in the CROSS group (HR, 0.70; 95% CI, 0.53–0.92; P = .012).[35][Level of evidence A1]
   • Neoadjuvant treatment was given to 403 patients: 207 patients in the FLOT group and 196 patients in the CROSS group.
   • Surgery was performed in 371 patients: 191 patients in the FLOT group and 180 patients in the CROSS group. R0 resection was achieved in 351 patients, including 180 patients in the FLOT group and 171 patients in the CROSS group.
   • More patients who received FLOT (87.3%) than CROSS (67.7%) were able to complete all planned neoadjuvant therapy.
   • The 90-day postsurgical mortality was 4.3%: 3.2% in the FLOT group and 5.6% in the CROSS group.
   In the ESOPEC trial, patients did not receive adjuvant nivolumab; thus, it is not possible to conclude that perioperative FLOT is superior to preoperative CROSS and adjuvant nivolumab.

Definitive Chemoradiation Therapy

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.[36,37] For patients with squamous cell carcinomas of the esophagus, definitive chemoradiation may offer equivalent outcomes, compared with preoperative chemoradiation followed by surgical resection.[38,39]

Evidence (definitive chemoradiation):

1. A Radiation Therapy Oncology Group trial (RTOG-8501) randomly assigned patients 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).[36][Level of evidence A1]

   • There was an improvement in the 5-year survival rate for the combined modality group (27% vs. 0%).
   • An 8-year follow-up of this trial demonstrated an OS rate of 22% for patients who received chemoradiation therapy.
2. 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.[37][Level of evidence A1]

   • 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 rates (31% vs. 40%), or local and regional failure rates (56% vs. 52%).
   • There was a higher treatment mortality rate 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.
3. An Eastern Cooperative Oncology Group trial (EST-1282) evaluated 135 patients.[40][Level of evidence A1]

   • 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.
4. The PRODIGE5/ACCORD17 trial (NCTE) compared the efficacy and safety of oxaliplatin, 5-FU, 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).[41][Level of evidence B1]

   • 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; increases in serum creatinine, mucositis, and alopecia were more common in the 5-FU and cisplatin group.
5. 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.[38][Level of evidence A1]

   • The analysis of 172 eligible randomly assigned patients showed that OS rates at 2 years were 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).
   • The local 2-year PFS rate was higher in the surgery group (64.3%; 95% CI, 52.1%–76.5%) than in the chemoradiation therapy group (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).
   • The treatment-related mortality rate was higher in the surgery group (12.8%) than in the chemoradiation therapy group (3.5%) (P < .03).
6. FFCD 9102 (NCTE) 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).[39][Level of evidence A1]

   • Of the 259 randomly assigned patients, 230 (89%) had squamous cell carcinoma, and 29 patients (11%) had adenocarcinomas.
   • The 2-year OS rate 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).

Adjuvant Therapy

Evidence (adjuvant therapy):

1. A global, randomized, double-blind, placebo-controlled, phase III trial evaluated a checkpoint inhibitor as adjuvant therapy in 794 patients with esophageal or gastroesophageal junction cancer. Adults with a performance status of 0 or 1 and R0 stage II or III disease who had received neoadjuvant chemoradiation therapy and had residual pathological disease were included. Patients were randomly assigned in a 2:1 ratio to receive either nivolumab (240 mg every 2 weeks for 16 weeks) followed by nivolumab (480 mg every 4 weeks) (532 patients) or matching placebo (262 patients). Patients were enrolled regardless of programmed death-ligand 1 (PD-L1) expression. The maximum duration of the trial intervention period was 1 year. The primary end point was DFS. The median follow-up was 24.4 months.[42][Level of evidence B1]

   • The median DFS was 22.4 months (95% CI, 16.6–34.0) among patients who received nivolumab, compared with 11.0 months (95% CI, 8.3–14.3) among patients who received placebo. The HR_{disease recurrence or death} was 0.69 (96.4% CI, 0.56–0.86; P < .001).
   • Median DFS was evaluated across a prespecified subgroup according to histological type. Among patients with adenocarcinoma, the median DFS was 19.4 months in the 376 patients who received nivolumab (95% CI, 15.9–29.4), compared with 11.1 months in the 187 patients who received the placebo (95% CI, 8.3–16.8); the HR_{disease recurrence or death} was 0.75 (95% CI, 0.59–0.96). Among patients with squamous cell carcinoma, the median DFS was 29.7 months (95% CI, 14.4 to not estimable) in the 155 patients who received nivolumab, compared with 11 months (95% CI, 7.6–17.8) in the 75 patients who received the placebo; the HR_{disease recurrence or death} was 0.61 (95% CI, 0.42–0.88).
   • HRs for disease recurrence or death were remarkably close between the 570 patients whose tumors expressed less than 1% of PD-L1 (HR, 0.73; 95% CI, 0.57–0.92) and the 129 patients whose tumors expressed 1% or more of PD-L1 (HR, 0.75; 95% CI, 0.45–1.24).
   • Grade 3 or 4 adverse events of any cause occurred in 183 of 532 patients (34%) in the nivolumab group and 84 of 260 patients (32%) in the placebo group, and serious adverse events of any grade occurred in 30% of the patients in each group (nivolumab: 158 of 532; placebo: 78 of 260). Adverse events that were considered by the investigators to be related to the trial regimen were more common with nivolumab than with placebo, including grade 3 or 4 events (nivolumab: 71 of 532 patients [13%]; placebo: 15 of 260 patients [6%]) and events leading to discontinuation of therapy (nivolumab: 48 of 532 patients [9%]; placebo: 8 of 260 patients [3%]).
   • OS data have not been reported for this study.

Given the positive results for the use of nivolumab after chemoradiation therapy and surgery in patients with esophageal cancer, an ongoing study will determine whether the adjuvant use of checkpoint inhibitor therapy improves outcomes in patients undergoing definitive chemoradiation therapy without surgery (KEYNOTE-975 [NCT04210115]). Studies are also evaluating potential benefits in patients undergoing perioperative chemotherapy without radiation therapy (e.g., KEYNOTE-585 [NCT03221426]).[43]

Immunotherapy and Chemoimmunotherapy

Postoperative Radiation Therapy

Two randomized trials have shown no significant OS benefit for postoperative radiation therapy compared with surgery alone.[51,52][Level of evidence A1] 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

At diagnosis, approximately 50% of patients with esophageal cancer have metastatic disease and are candidates for palliative therapy.[1]

Treatment options for stage IV esophageal cancer include the following:

1. Chemoradiation therapy followed by surgery (for patients with stage IVA disease).
2. Chemotherapy, which has provided partial responses for patients with metastatic distal esophageal adenocarcinomas.[2-4]
3. Adjuvant therapy for patients with completely resected (negative margins) esophageal adenocarcinoma, esophageal squamous cell carcinoma, or gastroesophageal junction cancer who had residual pathologic disease after concurrent chemoradiation therapy.[5]
4. Immunotherapy and chemoimmunotherapy for patients with previously untreated, unresectable, advanced or metastatic esophageal squamous cell carcinoma.[6-8]
5. Immunotherapy and chemoimmunotherapy for patients with previously untreated advanced or metastatic esophageal adenocarcinoma or gastroesophageal junction cancer.[8-10]
6. Immunotherapy for patients who relapse after one prior line of standard therapy.[11,12]
7. Nivolumab and chemotherapy for patients with adenocarcinoma.[9]
8. Nd:YAG endoluminal tumor destruction or electrocoagulation.[13,14]
9. Endoscopic-placed stents to provide palliation of dysphagia.[15]
10. Radiation therapy with or without intraluminal intubation and dilation.
11. Intraluminal brachytherapy to provide palliation of dysphagia.[16,17]
12. Clinical trials evaluating single-agent or combination chemotherapy.

The treatment of patients with human epidermal growth factor receptor 2 (HER2)-negative, locally advanced, inoperable, recurrent, or metastatic esophageal cancer has improved with the introduction of chemoimmunotherapy as front-line therapy and immunotherapy for patients who relapse following one prior line of chemotherapy. First-line chemoimmunotherapy can now be considered the standard of care for patients with advanced esophageal cancer of squamous or adenocarcinoma histology and programmed death-ligand 1 (PD-L1) expression (although the optimal cutoff still needs to be defined). For more information, see the Immunotherapy and Chemoimmunotherapy section.

Current Clinical Trials
