Pacemaker and radiotherapy in breast cancer: is targeted intraoperative radiotherapy the answer in this setting?

We present the case of an 83 year old woman with a cardiac pacemaker located close in distance to a subsequently diagnosed invasive ductal carcinoma of the left breast. Short range intraoperative radiotherapy was given following wide local excision and sentinel node biopsy. The challenges of using ionising radiation with pacemakers is also discussed.

Comment on papers by Chong et al., Nishio et al., and Suri et al. on diabetes reversal in NOD mice.

Chong et al., Nishio et al., and Suri et al. (Reports, 24 March 2006, pp. 1774, 1775, and 1778) confirmed that treating nonobese diabetic (NOD) mice with an immune adjuvant and semisyngenic spleen cells can reverse the disease but found that spleen cells did not contribute to the observed recovery of pancreatic islets. We show that islet regeneration predominately originates from endogenous cel...

Response by Caplan et al.

W e would like to thank Dr. Wong for the response to our article “No time to waste—the ethical challenges created by CRISPR”. Dr. Wong’s letter addresses a question about the relationship between biology and society: that “prevailing papers” on CRISPR-Cas9 rarely emphasize understanding the microbiological processes that make CRISPR-Cas9 an effective defensive mechanism. Instead, scientists and...

Systemic Targeted Alpha Radiotherapy for Cancer

Background: The fundamental principles of internal targeted alpha therapy for cancer were established many decades ago.The high linear energy transfer (LET) of alpha radiation to the targeted cancer cellscauses double strand breaks in DNA. At the same time, the short range radiation spares adjacent normal tissues. This targeted approach complements conventional external beam radiotherapy and ch...
