About this study

Patients pathologically confirmed with solid tumors that requires radiotherapy or surgery will be recruited to this study. Tumor samples were obtained from patients underwent surgery to establish the baseline status of biomarker assessed. Peripheral and microbiota will also be collected before and after surgery. For patients undergoing radiotherapy, tumor biopsy as well as collection of blood samples and microbiota will be performed during the course of treatment. These biological specimens will be used for assessment of tumor phenotypes and for exploration of potential biomarkers that could predict the tumor response to therapeutics and prognsis in patients with solid tumors.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Pathological proven diagnosis of solid tumors
  • Tumor accessible for biopsy during the course of radiotherapy or tumor samples could be obtained via surgery
  • Patient must provide study-specific informed consent prior to study entry

Exclusion criteria

  • History of autoimmune diseases
  • History of immunotherapy
  • Prior radiation therapy that would result in overlap of planned radiation therapy fields
  • Will receive immunotherapy during the course of radiotherapy
  • Contraindications for biopsy, such as high bleeding risk

Treatment and study plan

Primary outcomes

  1. Expression status of biomarkers and their dynamic changes during treatment and follow-up

    Time frame: From the date of enrollment until the date of disease progression, assessed up to 3 years

    Expression status of biomarkers and their dynamic changes in patients' biological specimens through the course of treatment and during follow-up as assessed by a variety of means, including RNA-seq, DNA-seq, RT-qPCR, IHC, WB and ELISA.

  2. Tumor short-term response to therapeutics

    Time frame: Within 1 month after the completion of radiotherapy

    For patients treated with radiotherapy, shortly after the completion of treatment, the short-term response was assessed by using the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST1.1) .

  3. Tumor long-term response to therapeutics

    Time frame: up to 3 years of follow-up

    For patients treated with radiotherapy, tumor response was assessed by using the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST1.1) .

Secondary outcomes

  1. Disease-specific survival

    Time frame: up to 3 years of follow-up

    The tumor disease-specific survival of patients

Other outcomes

  1. Overall survival

    Time frame: up to 3 years of follow-up

    The overall survival of patients
