From the Guidelines
The SCAPE chemotherapy regimen is not a standard first-line protocol and should be reserved for cases where standard protocols have failed or for specific tumor types that have shown sensitivity to multiple agents in this combination, due to its significant side effect risks and the availability of other effective treatment options 1.
Overview of SCAPE Regimen
The SCAPE chemotherapy regimen combines five anticancer drugs - Sunitinib, Capecitabine, Adriamycin (doxorubicin), Paclitaxel, and Epirubicin - for treating advanced or metastatic cancers. This regimen represents a combination approach sometimes used in complex cases where multiple mechanisms of action are needed.
Mechanism of Action
- Sunitinib targets tyrosine kinase receptors to block tumor growth and angiogenesis.
- Capecitabine is an oral prodrug that converts to 5-fluorouracil in tumor tissues.
- Adriamycin and Epirubicin are anthracyclines that intercalate DNA and inhibit topoisomerase II.
- Paclitaxel is a taxane that stabilizes microtubules and prevents cell division.
Treatment Considerations
- The specific dosing schedule typically involves careful sequencing to minimize overlapping toxicities.
- Particular attention should be given to cardiac monitoring due to the potential for cumulative cardiotoxicity from anthracyclines.
- This regimen carries significant side effect risks including myelosuppression, hand-foot syndrome, neuropathy, and cardiac dysfunction, requiring close monitoring of complete blood counts, cardiac function, and liver enzymes throughout treatment.
Clinical Application
- SCAPE is generally reserved for cases where standard protocols have failed or for specific tumor types that have shown sensitivity to multiple agents in this combination.
- According to the most recent guidelines, such as those from the National Comprehensive Cancer Network 1, other regimens like dose-dense AC followed or preceded by paclitaxel, or TC (docetaxel and cyclophosphamide), are preferred as first-line treatments for certain types of breast cancer, indicating that SCAPE is not typically considered a first-line option.
From the Research
SCAPE Chemotherapy Regimen
The SCAPE chemotherapy regimen consists of Sunitinib, Capecitabine, Adriamycin, Paclitaxel, and Epirubicin. However, there is limited information available on this specific combination of drugs.
Components of the SCAPE Regimen
- Sunitinib: a multi-targeted receptor tyrosine kinase inhibitor used in the treatment of various cancers, including renal cell carcinoma and gastrointestinal stromal tumor.
- Capecitabine: an oral chemotherapy drug used in the treatment of breast, colon, and rectal cancers, as seen in studies 2, 3, 4, 5.
- Adriamycin (Doxorubicin): a chemotherapy drug used in the treatment of various cancers, including breast cancer, as seen in studies 6.
- Paclitaxel: a chemotherapy drug used in the treatment of various cancers, including breast, lung, and ovarian cancers, as seen in studies 3, 5, 6.
- Epirubicin: a chemotherapy drug used in the treatment of various cancers, including breast cancer, as seen in studies 2, 4.
Application in Cancer Treatment
The SCAPE regimen is not a well-established or widely used chemotherapy regimen. However, its components have been used in various combinations to treat different types of cancer, including:
- Breast cancer: studies 3, 4, 6 have investigated the use of capecitabine, paclitaxel, and epirubicin in combination with other drugs to treat breast cancer.
- Gastric cancer: studies 2, 5 have investigated the use of capecitabine, paclitaxel, and epirubicin in combination with other drugs to treat gastric cancer.
Efficacy and Safety
The efficacy and safety of the SCAPE regimen are unknown, as there is limited information available on this specific combination of drugs. However, the individual components of the regimen have been shown to be effective and relatively safe when used in combination with other drugs to treat various types of cancer, as seen in studies 2, 3, 4, 5, 6.
