Primary Objectives - Initial Phase:
1. To estimate the risk of patient-reported oral and/or gastrointestinal (GI) mucosal injury among subjects being treated with chemotherapy or radiation therapy for solid tumors.
2. To describe the concordance between patient-reported oral mucosal injury and clinician-reported oral mucosal injury.
Secondary Objectives- Initial Phase:
1. To describe the clinical, patient-reported, and economic outcomes of mucosal injury,
by grade of mucositis. a. To estimate the risk of adverse clinical outcomes (modification of cancer
therapy dosing, drug selection, or treatment schedule) and adverse
economic outcomes (proportions of subjects requiring hospitalization,
TPN, narcotic analgesics, ER visits) among subjects with mucosal injury,
by grade of mucositis.
b. To describe patient-reported outcomes (mean quality of life and daily
functioning scores during mucosal injury and changes from baseline)
among patients with mucosal injury, by grade of mucositis, and to
determine the association between the presence and severity of mucosal
injury and important patient-reported outcomes including health-related
quality of life and daily functioning. 2. To compare adverse clinical, patient-reported, and economic outcomes among those
who develop mucosal injury, by grade, with those who do not develop mucosal injury; to
describe the association between the presence and severity of mucosal injury and risk of
important clinical and economic outcomes; and to derive an estimate of cost of treatment
of mucosal injury.
3. To compare the risk and severity of mucosal toxicity a) across regimens, within tumor
groups and b) across tumor groups, within treatment regimens.
4. To model the risk and severity of mucositis based on demographic and treatment
variables.
5. To describe the association between the presence and severity of mucositis and other
cancer-related toxicities, such as fatigue, weight loss, and cachexia.
