IORT with Electrons in Breast Cancer: 10-Year Results

Treatment Use

Electron IORT

Cancer Indication

Breast (Boost)

Number of Patients

770

Summary/Conclusion

This study provides 10-year outcome data of 770 stage I through III breast cancer patients who received intraoperative electron radiation therapy (IOERT) as a tumor bed boost preceding whole breast irradiation. After a median follow-up period of 121 months, 21 in-breast recurrences (2.7%) occurred with triple-negative and HER2fl subtypes as negative predictors. As confirmed in long-term follow-up, IOERT has been demonstrated to be a viable boost strategy in any risk constellation.

Intraoperative Radiation Therapy (IORT) in Pancreatic Cancer

Treatment Use

Electron IORT

Cancer Indication

Pancreatic

Number of Patients

Summary/Conclusion

Authors Robert Krempien and Falk Roeder Abstract Despite the important improvements made in the fields of surgery, chemotherapy and radiation therapy, pancreatic cancer remains one of the most lethal malignancies. Improved outcomes with novel chemotherapy regimes led again to increased attention on the role of localized radiotherapy, since local tumor progression causes significant morbidity and mortality … Continued

Total Neoadjuvant Therapy With FOLFIRINOX Followed by Individualized Chemoradiotherapy for Borderline Resectable Pancreatic Adenocarcinoma A Phase 2 Clinical Trial

Treatment Use

Mobetron

Cancer Indication

Pancreatic

Number of Patients

48

Summary/Conclusion

Patients with borderline-resectable pancreatic ductal adenocarcinoma have historically poor outcomes with surgery followed by adjuvant chemotherapy. Evaluation of a total neoadjuvant approach with highly active therapy is warranted.

Survival and local control rates of triple-negative breast cancer patients treated with boost-IOERT during breast-conserving surgery

Treatment Use

Electron IORT

Mobetron

Cancer Indication

Breast (Boost)

Number of Patients

71

Summary/Conclusion

The purpose of this work was to retrospectively evaluate survival and local control rates of triple-negative breast cancer subtypes classified as five marker negative (5NP) and core basal (CB), respectively, after breast-conserving surgery and intraoperative boost radiotherapy with electrons (IOERT) followed by whole breast irradiation.

Cancer Indication

Breast (Single-Fraction APBI)

Number of Patients

Summary/Conclusion

Recently, interest has also grown in intraoperative radiation therapy (IORT), which treats the partial breast with a single dose of radiation using either low-energy x-rays or electrons, most commonly delivered at the time of surgery. These different modalities are likely to have certain tradeoffs with regard to their effectiveness and toxicity profiles, although these tradeoffs have yet to be completely described in the existing literature.
