"Radioimmunotherapy, also known as systemic targeted radiation therapy, uses antibodies, antibody fragments, or compounds as carriers to guide radiation to the targets.
The NCCN Guidelines for Pancreatic Adenocarcinoma focus on diagnosis and treatment with systemic therapy, radiation therapy, and surgical resection.
Systemic internal radiation therapy using radiolabelled peptides, specifically targeting receptors overexpressed on tumour cells, is an attractive cancer treatment.
RESULTS: Consensus was established in areas involving response definitions, eligibility criteria for future trials, reirradiation, changes in systemic therapy, radiation techniques, parameters at follow-up, and timing of assessments.
Patients received gefitinib following standard systemic or radiation therapy and response was assessed radiographically according to the SWOG modification of the WHO criteria [ 20].
For advanced cancers or lesions in the inoperable patient, the benefit of local ablative therapies combined with systemic and radiation therapy for palliation has also been supported.
Exclusion criteria included visceral metastases, pathologic bone fractures, spinal cord compression, and treatment in the previous month with systemic glucocorticoids, radiation, surgery, or systemic therapy for prostate cancer, with the exception of medical or surgical castration.
All were potential candidates for active treatment of their cancer as an outpatient, and 90% were having systemic and/or radiation treatments at the time of this study.
The clinical standard of practice was to inform all patients about the extent of their cancer, its incurability, the expectations of a limited lifespan, the palliative goal of systemic and radiation treatment, the response to treatment and their overall progress.
