Background:
Pancreatic cancer is a deadly cancer with a 5-year survival rate less than 10%. Only 20% of patients are eligible to receive surgery at diagnosis. Hence, new therapies are needed to improve outcomes for non-surgical candidates. Thermal ablation techniques can offer a non-invasive alternative to surgery.
Aim:
The aim of this review is to map the literature for the use of thermal ablative techniques: Radiofrequency ablation (RFA), High-intensity focused ultrasound (HIFU), Microwave ablation (MWA), and Laser ablation (LA) in the management of patients with PC.
Methods:
A search strategy was applied to PUBMED and EMBASE using keywords concerning pancreatic cancer, radiofrequency ablation, ultrasound ablation, laser ablation, and microwave ablation. The studies that fit this inclusion criteria were summarized in table format and results reviewed for interpretation.
Results:
72 clinical studies were included. Most of the included studies related to RFA (n=35) and HIFU (n=27). The most common study design was retrospective (n=33). Only 3 randomized control trials (RCT) were included, all of which related to RFA. Safety outcomes were reported in 53 of the 72 studies, and survival outcomes were reported in 39. Statistically significant survival benefits were demonstrated in 11 studies.
Conclusion:
The evidence for the benefit of MWA and LA in PC patients is limited. RFA and HIFU are safe and feasible therapies to be used in PC patients. Further RCTs where thermal techniques are standardized and reported are necessary in the future to elucidate thermal ablation's clinical utility, and before an evidence-based decision on its routine use in PC management can be considered.
Insights
Thermal ablation techniques like Radiofrequency Ablation (RFA) and High-Intensity Focused Ultrasound (HIFU) show promise for pancreatic cancer management. Further research is needed to establish their routine clinical utility.
Area of Science:
- Oncology
- Minimally Invasive Surgery
Background:
- Pancreatic cancer has a poor prognosis with limited surgical options.
- New therapeutic strategies are crucial for patients ineligible for surgery.
- Thermal ablation offers a non-invasive treatment alternative.
Purpose of the Study:
- To review the literature on thermal ablative techniques for pancreatic cancer.
- To assess the use of Radiofrequency Ablation (RFA), High-intensity focused ultrasound (HIFU), Microwave ablation (MWA), and Laser ablation (LA).
Main Methods:
- Literature search conducted on PubMed and EMBASE.
- Keywords included pancreatic cancer and various thermal ablation modalities.
- Included studies were summarized and results interpreted.
Main Results:
- 72 clinical studies were reviewed, predominantly RFA (35) and HIFU (27).
- Most studies were retrospective (33), with only 3 randomized control trials (RCTs) on RFA.
- 11 studies demonstrated statistically significant survival benefits.
Conclusions:
- RFA and HIFU are safe and feasible for pancreatic cancer.
- Evidence for MWA and LA in pancreatic cancer is limited.
- Further standardized RCTs are required to determine the clinical utility of thermal ablation.
