Overview

This prospective, observational cohort study will evaluate the extent of associations between self-reported pro- or anti- inflammatory dietary intake patterns for one month before induction chemotherapy for gynecological cancer or neo/adjuvant chemotherapy for breast cancer and baseline serum hepcidin concentrations. Associations between hepcidin concentration and relative dose intensity (RDI) of chemotherapy will also be evaluated.

This is a prospective, observational cohort of 100 women receiving chemotherapy for breast or gynecological cancer at GW Cancer Center from July 1, 2024 - approximately September 2025. At study baseline (after diagnosis, but prior to starting chemotherapy), participants will complete a \~30-minute food frequency questionnaire (FFQ) and demographic/food security survey using a preprogrammed iPad in the clinic. The clinical research nurse will obtain an additional research blood draw at the same time as the patient's routine clinical blood draw prior to chemotherapy initiation for serum hepcidin concentration measurement. Data on cancer type, premorbid medical conditions, and chemotherapy plans and administration will be collected from the electronic health record by study staff and the duration of data collection will be the length of chemotherapy plus 30 days. Data will be used to address the objectives below. Among adult women scheduled to receive chemotherapy for breast or gynecological cancer treatment, the objectives/aims of this study will be to: 1. Determine the extent to which pretreatment, self-reported Dietary Inflammatory Index dietary pattern scores from dietary intake during the one month prior to chemotherapy initiation are associated with pretreatment serum hepcidin concentrations 2. Determine the extent to which pretreatment serum hepcidin concentrations are associated with chemotherapy RDI.

Outcomes

Primary Outcomes

Serum hepcidin concentration

ng/ml, continuous

Time frame: pre-chemotherapy, single measure

Chemotherapy relative dose intensity

Calculated variable that represents the ratio of chemotherapy actually received during the duration of treatment to the planned chemotherapy dose during the planned duration

Time frame: during chemotherapy (up to 6 months, depends on duration of chemotherapy regimen), represents repeated measures

Secondary Outcomes

Hematologic toxicity

Incidence of CTCAE grade 3 or higher hematologic toxicity (anemia, neutropenia, thrombocytopenia)

Time frame: at any point during chemotherapy or within 30 days after completion of chemotherapy (up to 6 months, depends on length of chemotherapy regimen)

Treatment delays

Delay of chemotherapy due to chemo-related adverse events, including hematologic toxicity, infection, hospitalization, or severe symptoms

Time frame: at any point during chemotherapy (up to 6 months, depends on length of chemotherapy regimen)

Treatment change or discontinuation

Change of chemotherapy regimen or discontinuation of treatment due to chemo-related adverse events, including hematologic toxicity, infection, hospitalization, or severe symptoms

Time frame: at any point during chemotherapy (up to 6 months, depends on length of chemotherapy regimen)

Blood transfusion

Infusion of red blood cells, platelets, fresh frozen plasma, or other donated human blood products due to chemo-related hematologic toxicity

Time frame: at any point during chemotherapy or up to 30 days after completion of chemotherapy (up to 6 months, depends on length of chemotherapy regimen)

Hospitalizations

Unscheduled admission to a hospital or similar medical facility due to due to chemo-related adverse events, including hematologic toxicity, infection, or severe symptoms
