as needed (PRN)

Define mucositis?
erythematous ulcerative lesions of the mucosa observed in patients treated with chemotherapy and can occur ANYWHERE IN GI TRACT
Define stomatitis?
inflammation limited to the oral cavity
Explain the five-stage model of oral mucositis?
initiation, primary damage response, signal amplification, ulceration, healing
List risk factors of chemotherapy-induced mucositis?
smoking, poor oral hygiene, oral lesions at baseline, female sex, pretreatment nutritional status, chemotherapy (melphalan, cisplatin + radiation, high-dose MTX, doxorubicin, busulfan, 5-FU)
What are treatment options for management of chemotherapy-induced mucositis?
oral decontamination with mouthwash (dexamethasone for Everolimus-induced), pain control (2% viscous lidocaine), artificial saliva products or chewing gum, liquid/soft diets/TPN, fluconazole for oral candidiasis
List patient risk factors for febrile neutropenia?
prior chemo/radiation, bone marrow involvement, recent surgery/open wounds, liver/renal dysfunction, >65 years receiving full chemo doses
Who should be given G-CSFs for febrile neutropenia primary prevention?
those with a risk >20% (high)
What are treatments for febrile neutropenia primary prevention?
filgrastim, pegfilgrastim, eflapegrastim-xnst or efbemalengrastim alfa-vuxw
What is the difference between filgrastim and its analogues used for febrile neutropenia primary prevention?
filgrastim is given daily until ANC recovery and the others are single dose, and filgrastim should be continued for neutropenia that develops
What is the recommendation for secondary prevention of febrile neutropenia?
if no prior G-CSF give, if Hx of G-CSF consider chemo dose reduction or treatment change
What are treatments for cancer pain?
non-opioids, opioids both +/- adjuvants
