Arm | Intervention/treatment |
---|---|
Active Comparator: Multivitamin (MV)
1 multivitamin pill will be taken orally, daily starting on the first day of chemotherapy and continuing for no more than 30 days past the cumulative chemotherapy dose (until the next cycle starts)
|
Dietary Supplement: Multivitamin (MV)
Multivitamins containing no more than 10 mg of pyridoxine and/or 10 micrograms of Vitamin B12 will be given to the patients on this arm. Drug: Chemotherapy Patients are treated per standard of care according to the choice of the treating physician with heavy metals (cisplatin, oxaliplatin), taxanes (paclitaxel, docetaxel), or vinca alkaloids (vincristine, vinorelbine) Ranges of cumulative doses (in mg/m2) are: paclitaxel, 700-960; docetaxel, 240-400; vincristine, 8-16; vinorelbine, 360-480; cisplatin, 240-400; oxaliplatin, 400-800; abraxane, 1200-1800 Other Names:

Experimental: Multivitamin + Vitamin B12 + Vitamin B6
1 multivitamin pill will be taken orally, daily starting on the first day of chemotherapy and continuing for no more than 30 days past the cumulative chemotherapy dose (until the next cycle starts). The patient will also take the following, starting on the first day of chemotherapy:

Dietary Supplement: Multivitamin + Vitamin B12 + Vitamin B6
Multivitamin (containing no more than 10 mg of pyridoxine and/or 10 micrograms of Vitamin B12), plus Vitamin B6 tablets and Vitamin B12 injections Drug: Chemotherapy Patients are treated per standard of care according to the choice of the treating physician with heavy metals (cisplatin, oxaliplatin), taxanes (paclitaxel, docetaxel), or vinca alkaloids (vincristine, vinorelbine) Ranges of cumulative doses (in mg/m2) are: paclitaxel, 700-960; docetaxel, 240-400; vincristine, 8-16; vinorelbine, 360-480; cisplatin, 240-400; oxaliplatin, 400-800; abraxane, 1200-1800 Other Names:

- Neurotoxicity Assessment at Baseline [ Time Frame: At study start; prior to treatment (week 0) ]Neurotoxicity is evaluated using The Functional Assessment of Cancer Therapy-Taxane (FACT-Tax) questionnaire. FACT-Tax is a validated, self-reported instrument. The questionnaire consists of 11 questions and possible scores for each question range from 0 (no neurotoxicity symptoms) to 4 (worst possible neurotoxicity symptoms). The total score for any patient can therefore range from 0 to 44. The questionnaire is given to patients to fill out at baseline (prior to chemotherapy treatment) and the mean total score for all patients is reported.
- Neurotoxicity Assessment at Cycle 2 [ Time Frame: 2 weeks ]Neurotoxicity is evaluated using The Functional Assessment of Cancer Therapy-Taxane (FACT-Tax) questionnaire. FACT-Tax is a validated, self-reported instrument. The questionnaire consists of 11 questions and possible scores for each question range from 0 (no neurotoxicity symptoms) to 4 (worst possible neurotoxicity symptoms). The total score for any patient can therefore range from 0 to 44. The questionnaire is given to patients to complete at completion of cycle 2 of chemotherapy treatment and the mean total score for all patients is reported.
- Neurotoxicity Assessment at Cycle 4 [ Time Frame: 4 weeks ]Neurotoxicity is evaluated using The Functional Assessment of Cancer Therapy-Taxane (FACT-Tax) questionnaire. FACT-Tax is a validated, self-reported instrument. The questionnaire consists of 16 questions and possible scores for each question range from 0 (no neurotoxicity symptoms) to 4 (worst possible neurotoxicity symptoms). The total score for any patient can therefore range from 0 to 44. The questionnaire is given to patients to fill out at completion of cycle 4 of their chemotherapy treatment and the mean total score for all patients is reported.
- Change in Neurotoxicity Assessment Between Cycle 4 and Baseline [ Time Frame: 4 weeks ]Neurotoxicity is evaluated using The Functional Assessment of Cancer Therapy-Taxane (FACT-Tax) questionnaire. FACT-Tax is a validated, self-reported instrument. The questionnaire consists of 11 questions and possible scores for each question range from 0 (no neurotoxicity symptoms) to 4 (worst possible neurotoxicity symptoms). The total score for any patient can therefore range from 0 to 44. The questionnaire is given to patients to fill out at baseline, cycle 2, and cycle 4 of their chemotherapy treatment. Change in neurotoxicity scores from baseline to the completion of 4 cycles are reported as the mean total score for all patients.
