Personalization of External Beam Radiation Therapy in Localised Tumours

Summary

The study will include the prospective acquisition of optimized MR imaging data of prostate and breast patients treated with radiotherapy (RT). Within the prospective study, biological specimens from patients undergoing in-room biopsy before RT, will be collected. Histological evaluation and cell culture (and organoid preparation) will be conducted, and samples/organoids will be irradiated with RT for biological validation.

Eligibility

Inclusion criteria for prostate patients:

* Unifocal infiltrating ductal breast carcinoma, non-special histotype

* Good general condition (ECOG 0-2)
* Expected active treatment (crioablation or surgery or radiotherapy ).

Exclusion Criteria:

* Exclusion criteria for prostate patients:

  * Mental disorders that cannot ensure valid informed consent

Exclusion criteria for breast patients:

* Histology other than non-special histotype and non-epithelial tumors (sarcoma, lymphoma)
