Lymphoma
Conditions
Brief summary
The next-generation sequencing (NGS) based on liquid biopsy has been an emerging technology to identify tumor-specific genetic aberrations in malignant tumors. The tumor tissue (FFPE) and plasma samples from the newly diagnosed pediatric lymphoma patients were collected and sequenced by 475 genes panel before, during and post treatment, to evaluate the significance of the ctDNA in efficacy prediction, predicting recurrence or mechanism of resistance to chemotherapy for pediatric lymphoma.
Detailed description
This is a prospective, multi-center, observational cohort study. The tumor tissue (FFPE) and plasma samples (bone marrow or cerebrospinal fluid samples if necessary) from the newly diagnosed patients were collected and sequenced by 475 genes panel before, during and post treatment. Collection and analysis the results of ctDNA and chemotherapy response, to explore the mutation map of pediatric lymphoma and to evaluate the significance of liquid biopsy for efficacy prediction, predicting recurrence, mechanism of resistance to chemotherapy.

Exclusion criteria
* Patients with any of the following items will not be enrolled in this study: 1. Incomplete baseline samples (preoperative plasma samples, tissue, bone marrow, cerebrospinal fluid) due to various reasons; 2.
