Theranostics is a medical approach that combines therapy and diagnostics to help guide personalized cancer treatment. It generally uses a target found on cancer cells that can first be identified through a diagnostic imaging agent and then used as a pathway for delivering a therapeutic agent. This allows healthcare professionals to evaluate whether a particular target is present before considering a corresponding treatment.
Theranostics generally begins with identifying a biological target associated with a particular cancer. A diagnostic compound designed to recognize that target may be used with medical imaging to determine whether cancer cells containing the target are present. If the imaging results show that the target is sufficiently expressed, a therapeutic compound designed to interact with the same target may be considered.
This approach can support more individualized treatment decisions because it connects diagnosis with therapy. Important aspects include:
Theranostics is being studied and used in selected cancers, including some neuroendocrine tumors and prostate cancers. The specific agents and treatment approaches depend on the cancer, molecular target, regulatory approvals, and individual patient circumstances.
Targeted cancer treatment aims to affect cancer cells based on particular molecular features. Theranostics may make this approach more precise by using diagnostic information to identify patients whose tumors contain the relevant treatment target. However, it is not suitable for every cancer or every patient.
Potential considerations include:
The use of theranostics represents one part of the broader development of precision oncology. Doctors may consider it alongside surgery, radiation therapy, chemotherapy, immunotherapy, targeted medicines, and other approaches depending on the patient's cancer and overall health.
theranostics connects cancer diagnosis and targeted treatment through the use of specific molecular targets. By identifying these targets through diagnostic methods and potentially directing therapy toward them, the approach can contribute to more personalized cancer care. Its suitability depends on the characteristics of the cancer and the available medical options, so treatment decisions should be made with qualified healthcare professionals based on individual clinical circumstances.
