Abstract
INTRODUCTION
Interventional oncology (IO) is an essential component of cancer care, which has gained substantial recognition in recent years. The aim of this review is to evaluate the level of evidence supporting IO and its inclusion in cancer treatment guidelines.
METHODS
A literature search of the PubMed database was performed to identify publication numbers and types for IO treatments published between 2012 and 2022. Selected cancer treatment guidelines and recommendations were reviewed for their inclusion of IO treatments.
RESULTS
With 68%, the majority of studies on IO treatments are case reports while randomised controlled trials (RCTs) amount only to 7% of studies. Despite this, IO studies have generated sufficient data to support the inclusion of IO treatments in cancer treatment guidelines and recommendations. This was frequently based on large prospective patient cohorts that corresponded to 24% (20% non-randomised studies and 4% observational studies) of all analysed studies rather than RCTs.
CONCLUSION
The level of evidence underpinning IO, as well as inclusion of IO in treatment guidelines and recommendations have increased substantially in recent years, indicating the growing importance and acceptance of IO in cancer care. The difficulty in conducting RCTs in IO is mitigated by the observation that they are not necessary to achieve guideline-inclusion. Nevertheless, it is crucial to conduct well-designed research projects to further consolidate the position of IO in the field of oncology. This will ensure that IO continues to evolve and meet the needs of cancer patients worldwide.
