SECONDARY outcome

Timeframe: Up to 2.5 years

Rates and associated 95% exact Clopper and Pearson binomial confidence limits will be estimated for objective response rate (complete response \[CR\] + partial response \[PR\]). RECIST: Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to \<10 mm Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. Additionally, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered progression Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study

SECONDARY outcome

Timeframe: CARG measured prior to treatment, toxicities and dose reduction measured up to 30 months

General linear models and descriptive methods will be used to explore factors as identified by a CARG assessment that may be predictive of toxicity (grade 3 or higher adverse events) or dose reduction. The cancer specific geriatric assessment score includes an evaluation of functional status, co-morbidity, cognition, psychological stats, social functioning and support, and nutritional status. It assesses a patient's age, gender, height, weight, cancer type, dosage, number of chemotherapy agents, hemoglobin, hearing, number of falls in past 6 months, able to take own medicine, whether walking is limited, have physical or emotional problems interfered with social activities and serum creatinine. Scores can range from 0 to to 1, with a higher score indicating higher risk of chemotherapy toxicity. Scores from 0 to 5 are considered low risk, 6 to 9 are considered intermediate risk, and 10 to 19 are considered high risk.
