简要总结
Many of the pediatric malignancies are not curable on progression on front line or 2nd line chemotherapy. Further therapy with conventional drugs imposes many side effects and decreases the QOL. The usual therapy offered to such patients is best supportive care.
Metronomic chemotherapy can induce tumor stabilization or tumor responses in patients with cancer that are refractory or have relapsed after conventional chemotherapy. Whether metronomic therapy is better than best supportive care is not known. In order to do so, a study is required which may compare metronomic therapy with a placebo therapy on PFS and QOL in relapsed refractory cases of pediatric solid tumors who have failed at least two lines of chemotherapy.
HYPOTHESIS
The investigators hypothesize that metronomic chemotherapy in progressive pediatric malignancy will improve PFS and QOL. If validated, then this form for therapy will be an option for both the patients and the clinicians, who are left with just an option of best supportive care in such situations of progressive pediatric cancers despite multiple lines of chemotherapy.

It will be double blind randomized study. One group will receive metronomic therapy along with best supportive care and other will receive placebo and best supportive care.
The treatment will be continued till progression is documented. Metronomic chemotherapy schedule : Alternating cycles of Cycle A and B (Each cycle includes 3 weeks of drug administration) with each drug rounded off to the nearest tablet/capsule size.
