Lung cancer, one of the malignant tumors which poses a threat to human's health, has increased morbidity and mortality recently. Radiotherapy, as one of the common treatments, has important value in clinical application. Esophageal cancer, one of the most common digestive system cancers, has poor prognosis and high mortality. Esophageal cancer has high aggressive and many patients can't get surgical treatment because of the tumor metastasis at the time of diagnosis.Currently, chemoradiotherapy has become one of the standard treatment regimens for patients with unresectable esophageal cancer in National Comprehensive Cancer Network(NCCN). So radiotherapy is one of the most important treatments in esophageal cancer.
Currently, the efficacy evaluation method of radiotherapy is by imaging examination after several courses of treatment. However, new reports suggest that circulating tumor DNA(ctDNA) has the potential to be an indicator of therapeutic effectiveness and recurrence risk.
|Condition or disease|
|Lung Cancer Esophageal Cancer|
Circulating free DNA (cfDNA) can be found dissolved in plasma and serum, at variable amounts. In the case of cancer patients, ctDNA is a fraction of the cfDNA derived from tumor. Currently, the ctDNA is widely used in "liquid biopsy" for not only does it carry the same somatic alterations as the tumor itself but also its percentage is correlated with tumor burden.
This study will investigate the clinical value of efficacy evaluation and prognosis of ctDNA detecting technique in patients with radiotherapy.
