(19 cards)
What treatment increases reactions to lungs and heart?
Doxorubicin delivered concomitantly.
What are the acute skin changes at 30 Gy?
Erythema.
What are the acute skin changes at 40 Gy?
Dry desquamation.
What are the acute skin changes at >50 Gy?
Moist desquamation.
What are the chronic skin changes due to radiation?
Telangiectasia, subcutaneous fibrosis, delayed wound healing, and necrosis.
What is a common side effect of radiation treatment?
Fatigue.
What is the incidence of pericarditis for small volumes receiving 60 Gy?
< 5%.
What is the incidence of pericarditis for larger volumes receiving 40 Gy?
< 5%.
What is the risk of radiation pneumonitis?
< 25 Gy, volume dependent.
What percentage of patients experience lymphedema after axillary irradiation?
25% - 30%.
What is the TD 5/5 for myelopathy?
50 Gy.
What angle should the SC field be off the cord?
10° - 15°.
What technique is used to reduce cord dose in IM treatment?
Mixed beam of photons and electrons.
What is the incidence of osteoradionecrosis in ribs with intangential fields?
< 1%.
What are acute radiation side effects?
Erythema, Dry Desquamation, Moist Desquamation, Fatigue
These are immediate reactions to radiation exposure.
What are long term complications of radiation?
Lung toxicity (TD 5/5 17Gy), Pneumonitis, Pulmonary Fibrosis, Breast and/or Arm Edema, Brachial plexus (46-50 Gy), Rib Fractures, Fibrotic tissue formation (60 Gy)
These complications may develop over time after radiation therapy.
What is the prognosis for patients with radiation treatment?
Prognosis is good overall even with positive lymph nodes. 5-year overall survival is 89% (all stages)
This indicates a favorable outcome for patients post-treatment.
What is the prognosis for patients with positive lymph nodes?
Prognosis is good overall even with positive lymph nodes.
What is the 5-year overall survival rate for all stages?
The 5-year overall survival rate is 89%.
