An eleven-year-old Galgo Espagnol was diagnosed with metastasized anal sac adenocarcinoma. The patient was enrolled into a clinical trial and underwent three “whole-body thermal therapy” (WBTT) sessions combined with four hypofractionated radiotherapy sessions during a ten-weeks’ time period. The medical device and corresponding treatment protocol were designed by ElmediX (ElmediX NV, Belgium). Air was injected at high speed in a treatment chamber and automatically regulated to reach and maintain a body temperature of 41.5°C for eight hours. Thermometry was ensured by temperature sensors placed in and on the patient. During four radiotherapy sessions, an external beam delivered hypofractionated doses of 6Gy on both the primary tumor and the metastatic lymph nodes. Clinical monitoring and assessment of quality of life confirmed that the WBTT sessions were well tolerated. Although burn wounds at pressure points occurred, prolonged severe adverse effects were not observed. Furthermore, the disease progression was deemed slower than the expected progression based on the literature.

The presented work deals with the uptake of gold nanoparticles (Au NPs) by M13 phages in solutions. In particular, the Au NPs uptake modalities and their localization in the filamentous phages are evaluated and measured. Gold spherical nanoparticles (with an average diameter of the order of 10 nm) are obtained by laser ablation in water with a sodium citrated surfactant. The interest of such application comes from the possibility to employ living biological structures to transport heavy metallic nanoparticles inside cells of tumoral tissues. Indeed, phages have the capability to introduce Au NPs in the proximity to the cell nucleus, increasing the efficiency of DNA destruction in the tumoral cells by employing low doses of ionizing radiation during radiotherapy and hyperthermia treatments. Several analyses and microscopy characterizations of the prepared phages samples embedding gold nanoparticles are presented, demonstrating that the presence of Au NPs increases the phages imaging contrast.
