Principally for GI, breast, and head and neck cancers.

Palliative treatment of carcinoma of the colon, rectum, anus, stomach, biliary tract, esophagus, and pancreas that is not amenable to surgery or irradiation.

Adjunct to surgery for the treatment of various solid tumors (e.g., adenocarcinoma of the colon, rectal carcinoma).

Drug of choice (combined with leucovorin) as an adjunct to surgery for colorectal cancer.

Drug of choice (combined with leucovorin and other drugs [e.g., irinotecan, oxaliplatin]) for metastatic colorectal cancer.

Combination fluorouracil/leucovorin regimens have replaced fluorouracil monotherapy regimens as adjuvant therapy for stage III disease.

Weekly schedule of fluorouracil/leucovorin (high-dose leucovorin or Roswell Park regimen) has equal efficacy as monthly schedule (low-dose or Mayo Clinic schedule), but the weekly schedule is a preferred regimen for adjuvant therapy because of ease of use and less toxicity. (See Colorectal Cancer under Dosage and Administration.)

Bimonthly, continuous IV infusion schedule of fluorouracil/leucovorin (LV5FU2 or deGramont regimen) also evaluated as adjuvant therapy and shown to be safer than direct IV injection regimen of these drugs. Simplified version of this regimen also evaluated. (See Colorectal Cancer under Dosage and Administration.)

Role of regional adjuvant therapy (e.g., portal vein or hepatic artery infusion) for liver metastases requires further elucidation.

Leucovorin and levoleucovorin enhance cytotoxicity, potentiate fluorouracil antineoplastic activity, and improve response for palliative advanced colorectal carcinoma treatment; designated an orphan drug by FDA for use with leucovorin for metastatic colorectal adenocarcinoma.

Leucovorin and levoleucovorin may potentiate risk of fluorouracil GI toxicity (e.g., diarrhea, nausea, stomatitis, vomiting) and myelosuppression.

Drug of choice for treatment of esophageal cancer.

Has been used alone and in combination therapy (e.g., with cisplatin) for the treatment of localized or advanced esophageal cancer.

Drug of choice combined with cisplatin for head and neck cancer.
