Outcome Measures
Primary Outcomes (1)
Toxicity of Radiotherapy Treatments
Acute and Late Toxicity evaluated with CTCAE (Common Terminology Criteria for Adverse Events) scale v6.0
Baseline, at 3, 6 month, one year from the end of radiation treatment, then yearly up to 3 years
Secondary Outcomes (3)
Response to Radiotherapy treatments with curative intent
evaluated at 3 months, 6 months, 1 year from treatments
Pain response to Radiotherapy treatments with palliative intent
evaluated at 3 and 6 months after treatments
Progression free survival (PFS)
every 3 months after radiation treatments
Study Arms (4)
ADC's group
Patients undergoing ADC's drugs such as Trastuzumab Emtansine (TDM1), Trastuzumab Deruxtecan, Sacituzumab Govitecan
Cyclin-dependent kinases 4 and 6 inhibitors (CDK4/6 group)
Patients receiving Palbociclib or Ribociclib or Abemaciclib
Anti Human Epidermal Growth Factor Receptor 2 monoclonal antibodies (Anti-Her2 group)
Patients receiving Trastuzumab or Trastuzumab Pertuzumab
IT group
