head and neck CA Flashcards
re: how treatment has evolved, what has surpassed surgery in frequency?
RXT: radiation therapy
re: how treatment has evolved, assumption is that ______ = better outcomes, but is not always true for swallowing
organ preservation
re: how treatment has evolved, when organ is preserved, often times ___ is not
function (of organ)
re: how treatment has evolved, the addition of ____ doubles mucosal toxicity
chemotherapy
incidence of dysphagia in H&N CA
34%-77% in first 90 days
9%-50% in 2 years
Aspiration= 22%-89% after RXT/chemo
early changes (up to 90 days) of radiation side effects
mucositis: pain, edema, ulceration, decreased saliva
swallowing: pain, decreased/thick saliva, taste changes
late changes (after 90 days) of radiation side effects
increase in collagen/fibrosis of connective tissue -> loss of elasticity/narrowing of structures
can involve muscle -> muscle necrosis, atrophy
can involve bone, nerve -> this may appear several years later
4 more late changes (after 90 days) of radiation side effects (terms)
osteoradionecrosis
trismus
decreased laryngo-pharyngeal sensation
continued xerostomia
what we see (in a patient with H&N CA)
edema/lymphedema structures eroded decreased hypo laryngeal elevation decreased CP opening decreased base of tongue motion decreased bolus clearance
name the term:
abnormal collection of protein-rich fluid in the interstitium resulting from obstruction of lymphatic drainage.
this causes pain, decreased movement, swelling, stiffness.
characterized by puffiness and pitting
lymphedema
name the term:
damage to the skin and subcutaneous tissue.
characterized by hardened, stiff, dense tissue
fibrosis
treatment of lymphedema and fibrosis: many rehabilitation facilities have lymphedema specialists who treat it with ______
massage
treatment of lymphedema and fibrosis: fibrosis is usually treated with a _______. what else is a good option?
deeper massage
myofascial release
key concepts:
XRT/chemo ALWAYS hinders ____
swallowing
key concepts:
tongue, epiglottis, UES are key in ___
XRT
key concepts:
must work with patient before, during, and after _____
XRT/chemo
dysphagia may lead to what 2 things?
weight loss and negative effects on swallow function
___ may lead to XRT interruption
weight loss
XRT interruption leads to _____
decreased survival
dysphagia also leads to ____
immune system function
3 solutions to dysphagia
shielding
modifying method, manner, composition of intake (KEEP SWALLOWING)
exercises: jaw ROM, active exercises
pre-radiation education
perform a clinical swallow eval to see: if ca/tumor causing dysphagia, if they are safe, what baseline is, if they know expectations
4 possible side effects of radiation on swallowing
aspiration
GER
pharyngeal residue
xerostomia
laryngectomies and dysphagia: oral phase problems
cancers of oral structures loss of dentition odynophagia trismus xerostomia
