A - Regimen Name

CARBOplatin
Disease Site
Gynecologic - Endometrial
Intent
Palliative
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.
Rationale and Uses
For the treatment of advanced or recurrent endometrial cancer
B - Drug Regimen
| CARBOplatin | AUC 5-7 | IV | Day 1 |
|
May adjust Carboplatin dose to AUC target (using Calvert formula) or in response to platelet counts (using Egorin formula -if previously treated with thrombocytopenic agent), as outlined in Other Notes section.

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
Also refer to Appendix 6: "Dosage Modification for Hematologic and Non-Hematologic Toxicities".

* Use Egorin formula if isolated thrombocytopenia (See "Other Notes" section).
# Do not retreat unless platelets ≥ 100 x 109/L, ANC ≥ 1.5 x 109/L and toxicities have recovered to ≤ grade 2.
# Do not retreat unless platelets ≥ 100 x 109/L, ANC ≥ 1.5 x 109/L and toxicities have recovered to ≤ grade 2.

Recommended Clinical Monitoring
- CBC; baseline and regular
- Renal function tests; baseline and regular including electrolytes
- Clinical toxicity assessment for neurotoxicity, ototoxicity, hypersensitivity, bleeding, infection, nausea and vomiting; regular
- Grade toxicity using the current NCI-CTCAE (Common Terminology Criteria for Adverse Events) version
Suggested Clinical Monitoring
- Liver function tests; baseline and regular
- INR for patients receiving warfarin; baseline and as clinically indicated

L - Other Notes
Combination chemotherapy is favoured over single agent chemotherapy because of higher response rates.
Calvert Formula
DOSE (mg) = target AUC X (GFR + 25)
- Target AUC of 4 to 6 mg/mL·min (previously treated patients) or 6 to 8 mg/mL·min (previously untreated patients)
- AUC = product of serum concentration (mg/mL) and time (min)
- GFR (glomerular filtration rate) expressed as measured Creatinine Clearance or estimated from Serum Creatinine (by Cockcroft and Gault method or Jelliffe method)
(Calvert AH, Newell DR, Gumbrell LA, et al, Carboplatin dosage: Prospective evaluation of a simple formula based on renal function. J Clin Oncol, 1989; 7: 1748-1756)
Egorin Formula
Previously Untreated Patients-
DOSE (mg/m²) = 317{ (pre - nadir/ pre) 100 - 82.1} X (BSA / Cr Cl) + 447
Previously Treated Patients-
DOSE (mg/m²) = 317{ (pre - nadir/ pre) 100 - 92.4} X (BSA / Cr Cl) + 447
- Pre = pretreatment platelet count
- Nadir = platelet nadir desired
- BSA = Body Surface Area
- Cr Cl = Creatinine Clearance

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.

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.
Regimen Monographs
Refer to the New Drug Funding Program or Ontario Public Drug Programs websites for the most up-to-date public funding information.
The information set out in the drug monographs, regimen monographs, appendices and symptom management information (for health professionals) contained in the Drug Formulary (the "Formulary") is intended for healthcare providers and is to be used for informational purposes only. The information is not intended to cover all possible uses, directions, precautions, drug interactions or adverse effects of a particular drug, nor should it be construed to indicate that use of a particular drug is safe, appropriate or effective for a given condition.

The format and content of the drug monographs, regimen monographs, appendices and symptom management information contained in the Formulary will change as they are reviewed and revised on a periodic basis. The date of last revision will be visible on each page of the monograph and regimen. Since standards of usage are constantly evolving, it is advised that the Formulary not be used as the sole source of information. It is strongly recommended that original references or product monograph be consulted prior to using a chemotherapy regimen for the first time.
Some Formulary documents, such as the medication information sheets, regimen information sheets and symptom management information (for patients), are intended for patients. Patients should always consult with their healthcare provider if they have questions regarding any information set out in the Formulary documents.
