- Brief Summary
An observational study of the relationship between fat free mass and toxicity of cytostatics in cancer patients, at the department of Clinical Oncology at Zealand University Hospital, Roskilde, Denmark. Fat free mass will be measured by bio impedance spectroscopy and data on toxicity will be obtained from medical records and interviews/questionnaires with the patients.
- Detailed Description
With a prospective observational design, this study will examine whether there is a correlation between the total dose of cytostatics per measured fat-free mass (FFM) (mg cytostatic agent/kg FFM) and toxicity of cytostatics among cancer patients. The study will include patients with a primary diagnosis of any stage colorectal or pancreatic cancer.
The hypothesis is, that a higher total dose of cytostatics per FFM will correlate to more frequent and/or more severe toxicity than a lower total dose. In extension to this, we hypothesize that a loss of FFM during treatment, and thereby an increased total dose of cytostatics per FFM, will lead to more frequent and severe toxicity.
Recruitment and data collection will take place at the department of Clinical Oncology at Zealand University Hospital, Roskilde over about a five month period. Each patient will be included for two-four cycles of cytostatic treatment. FFM will be measured by bio impedance spectroscopy as close to the first day of each cycle of cytostatic treatment as possible. Information about toxicity will be obtained from patient records and through interviews with the patients. Interviews will be conducted at day 5 (4-6) of each cycle and at the end of each cycle. The interviews include questionnaires about specific toxicities, using National Cancer Institute (NCI) Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE), and overall health and quality of life, and 24-hour recall of dietary intake and questions about physical activity level.
In short, relevant outcomes are change in FFM, hematology, grade 3/4 hematological toxicity as defined by NCI CTCAE, dose-limiting toxicity, hospitalization, patient-reported adverse events, overall health and quality of life, and nutritional intake.

Mmol of haemoglobin/L (per cycle - see outcome 1) During two-four cycles, depending on regime (about eight-nine weeks), and within each cycle (each cycle is 14, 21 or 28 days) Correlation between change i absolute and relative mmol of haemoglobin/L from baseline, and total dose of cytostatic agent (mg) pr. fat free mass (kg)
Febrile neutropenia During two-four cycles, depending on regime (about eight-nine weeks), and within each cycle (each cycle is 14, 21 or 28 days) Correlation between incidence of absolute neutrophilic granulocyte count \<1.0 x 10e9/L, with a single temperature of \>38.3 degrees C or a temperature of \>= 38 degrees C lasting for more than one hour, and total dose of cytostatic agent (mg) pr. fat free mass (kg)
Change in fat free mass between cycles of cytostatic treatment (each cycle lasts for 14, 21 or 28 days, depending on the type of regime) During and between two-four cycles, depending on regime (each cycle is 14, 21 or 28 days, depending on the regime) Changes in fat free mass, measured at baseline and the beginning of each cycle, between cycles of cytostatic treatment, and correlation with dose of cytostatic agent (mg) pr. fat free mass (kg)
Anemia During two-four cycles, depending on regime (about eight-nine weeks), and within each cycle (each cycle is 14, 21 or 28 days) Correlation between incidence of haemoglobin \<4,9 mmol/L(; transfusion indicated) and total dose of cytostatic agent (mg) pr. fat free mass (kg)
Thrombocyte count (per cycle - see outcome 1) During two-four cycles, depending on regime (about eight-nine weeks), and within each cycle (each cycle is 14, 21 or 28 days) Correlation between change i absolute and relative thrombocyte count from baseline, and total dose of cytostatic agent (mg) pr. fat free mass (kg)
Neutropenia During two-four cycles, depending on regime (about eight-nine weeks), and within each cycle (each cycle is 14, 21 or 28 days) Correlation between incidence of absolute neutrophilic granulocyte count \<1.0 - 0.5 x 10e9/L and total dose of cytostatic agent (mg) pr. fat free mass (kg)

- Secondary Outcome Measures
Name Time Method Dose-limiting toxicity (DLT) During two-four cycles, depending on regime (about eight-nine weeks), and within each cycle (each cycle is 14, 21 or 28 days) Correlation between DLT and total dose of cytostatic agent (mg) pr. fat free mass (kg).
DLT is defined as toxicity leading to one or more of the following: Dose reduction of one or more cytostatic agent(s) (recorded as mg and %). Postponement of cytostatic therapy (recorded as number of days). Discontinuation of cytostatic therapy before scheduled.
Causes of DLT (that are registered in patients records) are classified in one or more of the following categories: Infection, organ impact, myelosuppression, gastrointestinal discomfort, neuropathy or other toxicity (which one is recorded).Hospitalization During two-four cycles, depending on regime (about eight-nine weeks), and within each cycle (each cycle is 14, 21 or 28 days) Hospitalization note in patient record. Correlation between incidence and number of days of hospitalization and total dose of cytostatic agent (mg) pr. fat free mass (kg).
