Medication Summary

Most of the chemotherapy agents currently used for the treatment of esophageal cancer have not been approved by the US Food and Drug Administration (FDA) for this specific indication. Drug classes used in these regimens include alkylating, antimetabolite, anthracycline, and antimicrotubular agents. However, several biologic agents, such as programmed death ligand 1 (PD-L1) inhibitors have received FDA approval for use in esophageal cancer, and trastuzumab has been approved for use in esophagogastric junction adenocarcinoma that overexpresses HER2.

Antineoplastics, Antimetabolite

Class Summary

These agents inhibit cell growth and proliferation. They interfere with DNA synthesis by blocking the methylation of deoxyuridylic acid.

Fluorouracil (Adrucil)

Fluorouracil is a pyrimidine antimetabolite. Several mechanisms of action have been proposed, including inhibition of thymidylate synthase and inhibition of RNA synthesis. This agent is also a potent radiosensitizer.

Capecitabine (Xeloda)

Capecitabine is a pyrimidine antimetabolite and a prodrug of fluorouracil. It forms the active moiety, fluorouracil, by undergoing hydrolysis in the liver and tissues. Capecitabine is used for the treatment of esophageal cancer, which is an off-label indication.

Antineoplastics, Alkylating

Class Summary

These agents inhibit cell growth and proliferation, interfering with DNA synthesis by the formation of DNA cross-links. Alkylating agents can have serious adverse effects such as bone marrow suppression, anaphylactic-like reactions, ototoxicity, renal toxicity, and vomiting.

Cisplatin

Intrastrand cross-linking of DNA and inhibition of DNA precursors are among the proposed mechanisms of action for cisplatin. This agent is used in combination with radiation therapy. Cisplatin has black box warnings for adverse reactions, including anaphylactic-like reactions, ototoxicity, and renal toxicity.

Carboplatin

Carboplatin is a platinum alkylating agent that interferes with the function of DNA by producing interstrand DNA cross-links. It can be used in combination with paclitaxel for the treatment of esophageal cancer, which is an off-label indication. Carboplatin has black box warnings including bone marrow suppression, anaphylactic reactions, and vomiting.

Oxaliplatin (Eloxatin)

Oxaliplatin is a platinum alkylating agent that inhibits DNA replication and transcription, resulting in cell death. It can be used in combination chemotherapy for the treatment of esophageal cancer, which is an off-label indication. It has a black box warning for anaphylactic reactions, which can be managed with epinephrine, corticosteroids, and antihistamines.

PD-1/PD-L1 Inhibitors

Class Summary

PD-1 and related target PD-ligand 1 (PD-L1) are expressed on the surface of activated T cells under normal conditions. PD-L1/PD-1 interaction inhibits immune activation and reduces T-cell cytotoxic activity when bound.

Nivolumab (Opdivo)

Indicated in combination with fluoropyrimidine- and platinum-containing chemotherapy as first-line treatment for advanced or metastatic gastric cancer, gastroesophageal junction cancer, or esophageal adenocarcinoma. 

Pembrolizumab (Keytruda)

Indicated in combination with fluoropyrimidine- and platinum-containing chemotherapy as first-line treatment for advanced or metastatic gastric cancer, gastroesophageal junction cancer, or esophageal adenocarcinoma that is not amenable to surgical resection or definitive chemoradiation. Also indicated as a single agent for recurrent, locally advanced or metastatic, squamous cell carcinoma of the esophagus (ESCC) whose tumors express programmed death ligand 1 (PD-L1) with a Combined Positive Score (CPS) 10 or greater, as determined by an FDA-approved test, with disease progression after 1 or more prior lines of systemic therapy.

Antineoplastics, Antimicrotubular

Class Summary

These agents prevent cell growth and proliferation. They work by enhancing tubulin dimers, stabilizing existing microtubules, and inhibiting microtubule disassembly.

Docetaxel (Taxotere, Docefrez)

Docetaxel inhibits the depolymerization of tubulin, which inhibits DNA, RNA, and protein synthesis. It can be used in combination with cisplatin and fluorouracil for the treatment of esophageal cancer, which is an off-label indication. It has several black box warnings such as bone marrow suppression, fluid retention, and hypersensitivity reactions.

Use of docetaxel is not recommended in certain patients with hepatic impairment. Patients receiving treatment with docetaxel should be premedicated with corticosteroids the day before administration to help reduce fluid retention and hypersensitivity reactions.

Paclitaxel

Paclitaxel promotes microtubule assembly, interferes with the G2 mitotic phase, and inhibits cell replication. Although not FDA approved, it has been used in combination chemotherapy for the treatment of esophageal cancer. Paclitaxel has an off-label indication for the treatment of adenocarcinoma. Black box warnings for this drug include bone marrow suppression and hypersensitivity reactions.

Antineoplastics, Anthracycline

Class Summary

Anthracycline antineoplastics inhibit DNA and RNA synthesis by steric obstruction. They intercalate between DNA base pairs and trigger DNA cleavage by topoisomerase II.

Epirubicin (Ellence)

Epirubicin inhibits DNA and RNA synthesis. It can be used off label as part of a combination chemotherapy regimen for the treatment of esophageal cancer. It has several black box warnings, including bone marrow suppression, extravasation, myocardial toxicity, and secondary malignancy. Dosage reduction is recommended in patients with mild to moderate hepatic impairment.

Antineoplastics, Topoisomerase Inhibitors

Class Summary

These agents prevent cell growth and proliferation. They work by binding to topoisomerase and causing single-strand DNA breaks.

Irinotecan (Camptosar)

Irinotecan binds reversibly to the topoisomerase I–DNA complex and prevents the ligation of the cleaved DNA strand. It can be used as part of combination chemotherapy for the treatment of esophageal cancer, which is an off-label indication. Black box warnings for irinotecan include bone marrow suppression and diarrhea.

Thymidine Analog

Class Summary

Following uptake into cancer cells, trifluridine is incorporated into DNA, interferes with DNA synthesis and inhibits cell proliferation.

Tipiracil/trifluridine (Lonsurf)

Tipiracil is a thymidine phosphorylase inhibitor that increases trifluridine exposure by inhibiting its metabolism. Trifluridine is a thymidine-based nucleoside analog that incorporates into DNA, interferes with DNA synthesis, and inhibits cell proliferation. It is indicated for metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma previously treated with at least 2 prior lines of chemotherapy that included a fluoropyrimidine, a platinum, either a taxane or irinotecan, and if appropriate, HER2/neu-targeted therapy.

Antineoplastics, Other

Class Summary

This category includes miscellaneous antineoplastic agents that cause cytotoxic activity by various mechanisms of action.

Porfimer (Photofrin)

Porfimer is a photodynamic therapy that causes cytotoxic activity by producing oxygen free-radicals in the presence of laser light. It also can release thromboxane A2, leading to necrosis and vascular occlusion. It is indicated for palliation in patients with partially or completely obstructing esophageal cancer.
