Impact of Fat-free Mass in the Carboplatin Calculated Dose and Chemotherapeutic Toxicity in Patients With Advanced NSCLC
- Registration Number
- NCT02734069
- Lead Sponsor
- Instituto Nacional de Cancerologia de Mexico
- Brief Summary
This study evaluate the association of body composition (mainly free-fat mass), clinical and biochemical parameters with development of toxicity in patients under treatment with Carboplatin/Paclitaxel in advanced NSCLC.
- Detailed Description
BACKGROUND
Lung cancer (LC) is the leading cause of cancer deaths worldwide, are attributed about 13% of all new cases of cancer and accounts for 19.4% of deaths from malignancies. In Mexico, this cancer is also the leading cause of death in malignant neoplasias. One of the reasons attributable the high mortality from this disease is that most cases are detected in advanced stages and this depends prognosis and treatment. Within the classification of LC the most prevalent is the Non Small Cell Lung Cancer (NSCLC); for which the considered first-line standard treatment is palliative cytotoxic chemotherapy, as the combination of carboplatin with paclitaxel and in the other hand one of the most recent combinations Carboplatin with Pemetrexed.
Malnutrition may affect 80% of patients with advanced cancer and is associated with up to 20% of deaths, with an increased risk in the development of complications and mortality and can extend the hospital stay up to 90%, increasing the cost of treatment in a 35-75%. Similarly, in a previous study at INCan, the degree of malnutrition in patients with LC was associated with cytotoxic chemotherapy toxicity and poorer prognosis and poorer quality of life. Sarcopenia is also a phenomenon commonly observed in patients with LC, there has been a prevalence of 61% and 31% in men and women respectively.
Carboplatin dose that is administered to the patient is calculated by the Calvert formula, this requires the calculation of glomerular filtration rate (GFR). There are various quantified and estimated methods to calculate GFR; however the validated and most commonly used is estimated by the Cockroft-Gault formulae. It is known that due to various factors, variables required for calculation (as creatinine) could be modify the result, may became unreliable, it is why it is important to consider changes in body composition of NSCLC patients with sarcopenia.
HYPOTHESIS:
Sarcopenia participants receive a 20% more dose of Carboplatin per Free Fat Mass (kg / mg) than those without sarcopenia.
Sarcopenic patients, have more severe toxicity related to chemotherapy than those without sarcopenia.
METHODOLOGY:
NSCLC patients with advanced NSCLC (inoperable stage III or IV ) will be included.
Clinicopathological baseline of patients such as age, sex, stage, ECOG, weight, height, body composition, Subjective Global Assessment, frequency of food consumption, albumin, hemoglobin, hematocrit, glomerular filtration rate, carboplatin administered dosage, quality of life, etc.
A subsequent follow-up evaluation will be made after 1st and 2nd cycle of treatment to assess toxicity.

- Arm && Interventions
Group Intervention Description Non Sarcopenic Carboplatin Patients without sarcopenia (evaluated according to CT scans) will be followed up through treatment with carboplatin for identification of any toxicity grade 3 or 4 (Common Terminology Criteria of Adverse Events) Sarcopenic Carboplatin Patients with sarcopenia (evaluated according to CT scans) will be followed up through treatment with carboplatin for identification of any toxicity grade 3 or 4 (Common Terminology Criteria of Adverse Events)
- Primary Outcome Measures
Name Time Method Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 Six weeks after the application of chemotherapy to detect changes from Baseline Determine if the dose of carboplatin-based chemotherapy in patients according to the amount of fat-free mass is directly associated with toxicity
- Secondary Outcome Measures
Name Time Method Compare different formulas to calculate Glomerular Filtration Rate taking as gold standard cystatin c Basal evaluation Calculate the glomerular filtration rate given the amount of fat-free mass (MSA-eCrCl) and correlate with cystatin C and formulas as Cockroft-Gault, Levey, The Modification of Diet in Renal Disease (MDRD) and Chronic kidney disease epidemiology collaboration (CKD-EPI).
