Abstract:
Clinical verification is being obtained, with a variety of different therapeutic approaches, for the concept that anticancer treatments based on exploiting the host's own antitumor defense mechanism can be beneficial. Nevertheless, as was seen with both chemotherapeutic and radiation treatments, the benefit of single agent treatments is not great. It is anticipated that, in attempting to realize the maximal potential of anticancer treatments based on exploiting the host's own antitumor defense mechanism, it will be necessary to utilize combination therapies. For medical-ethical reasons, the ability to effectively combine such treatments with ones with proven clinical efficacy should increase the enthusiasm for the initiation of clinical trials. Chemotherapeutic agents may serve this purpose, since, contrary to the generally held tenet that anticancer chemotherapeutic agents are merely immunosuppressive, there is considerable literature describing their ability to augment antitumor host defenses. This review attempts to collate this information derived by numerous investigators employing diverse experimental approaches with a number of the most widely used anticancer chemotherapeutic agents.
Insights
Harnessing the host
Area of Science:
- Immunology
- Oncology
- Pharmacology
Background:
- Anticancer treatments leveraging host defense mechanisms show promise.
- Single-agent therapies, including chemotherapy and radiation, offer limited benefits.
- Combination therapies are essential for maximizing the potential of host-defense-based anticancer strategies.
Purpose of the Study:
- To review the literature on the immunomodulatory effects of chemotherapeutic agents.
- To explore the potential of combining chemotherapy with host-defense-based anticancer treatments.
- To support the initiation of clinical trials for novel combination anticancer therapies.
Main Methods:
- Systematic review of existing scientific literature.
- Collating data from diverse experimental approaches.
- Focusing on widely used anticancer chemotherapeutic agents.
Main Results:
- Chemotherapeutic agents can augment, rather than suppress, host antitumor defenses.
- Evidence suggests chemotherapy can enhance the efficacy of host-defense-based treatments.
- Numerous studies demonstrate the immunomodulatory capacity of various chemotherapeutics.
Conclusions:
- Combination therapy is crucial for optimizing anticancer treatments that exploit host immunity.
- Chemotherapy's ability to enhance host defenses supports its role in combination strategies.
- Further clinical trials are warranted to validate these combination approaches.
