FULCVR Regimen
Fluorouracil-Leucovorin


Disease Site
Gastrointestinal - Colorectal

Adjuvant

Regimen Category
Evidence-Informed :

Regimen is considered appropriate as part of the standard care of patients; meaningfully improves outcomes (survival, quality of life), tolerability or costs compared to alternatives (recommended by the Disease Site Team and national consensus body e.g. pan-Canadian Oncology Drug Review, pCODR).  Recommendation is based on an appropriately conducted phase III clinical trial relevant to the Canadian context OR (where phase III trials are not feasible) an appropriately sized phase II trial. Regimens where one or more drugs are not approved by Health Canada for any indication will be identified under Rationale and Use.

Antiemetic Regimen:

Low


Febrile Neutropenia Risk:

Low

Other Supportive Care:

May advise patients to suck on ice chips during bolus injection, to reduce stomatitis
 
E - Dose Modifications

Doses should be modified according to the protocol by which the patient is being treated. The following recommendations are in use at some centres.

Dosage with toxicity

Hematologic Toxicities:  See Appendix 6 for general recommendations.

Gastrointestinal Toxicities

Toxicity Dose
If Mucositis or Diarrhea ≥ Grade 3 in previous course REDUCE to 2/3 dose
If Hand-Foot Syndrome ≥ Grade 2 REDUCE to 2/3 dose



Hepatic Impairment

Omit if bilirubin > 4 x ULN (upper limit of normal).  Consider dose reduction with moderate to severe hepatic impairment.

 
F - Adverse Effects
Refer to leucovorin, fluorouracil drug monograph(s) for additional details of adverse effects

Bolus 5FU regimens have more myelosuppression and GI effects but less Hand-Foot Syndrome, compared to prolonged infusions.

Most Common Side Effects

Less Common Side Effects, but may be Severe or Life-Threatening

  • Myelosuppression ± infection
  • Stomatitis
  • Diarrhea
  • Myocardial ischemia, heart failure
  • Thromboembolism
  • Leukoencephalopathy
  • Optic neuritis
 
G - Interactions
Refer to fluorouracil, leucovorin drug monograph(s) for additional details
 
H - Drug Administration and Special Precautions
Refer to fluorouracil, leucovorin drug monograph(s) for additional details

If statutory holidays occur during therapy, that day should be omitted or therapy completed on Monday of the following week.
 
I - Recommended Clinical Monitoring

Treating physicians may decide to monitor more or less frequently for individual patients but should always consider recommendations from the product monograph.

Recommended Clinical Monitoring

  • Clinical toxicity assessment (including stomatitis).
  • CBC before each cycle. Interim counts should be done in first cycle and repeated if dose modifications necessary.
  • Baseline liver & renal function tests (if severe organ failure suspected).
  • Grade toxicity using the current NCI-CTCAE (Common Terminology Criteria for Adverse Events) version

Regimen Abstracts
A Regimen Abstract is an abbreviated version of a Regimen Monograph and contains only top level information on usage, dosing, schedule, cycle length and special notes (if available). It is intended for healthcare providers and is to be used for informational purposes only.

Such information is provided on an “as-is” basis, without any representation, warranty, or condition, whether express, or implied, statutory or otherwise, as to the information’s quality, accuracy, currency, completeness, or reliability, and Cancer Care Ontario disclaims all liability for the use of this information, and for any claims, actions, demands or suits that arise from such use.
Information in regimen abstracts is accurate to the extent of the ST-QBP regimen master listings, and has not undergone the full review process of a regimen monograph.  Full regimen monographs will be published for each ST-QBP regimen as they are developed.
