Evaluating blood lymphocyte changes in thoracic cancer patients undergoing treatment

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to assess the alterations and prognostic significance of peripheral blood lymphocyte subsets in patients diagnosed with thoracic cancers, specifically non-small cell lung cancer, esophageal squamous cell carcinoma, and thymic epithelial tumors. Participants will be monitored for changes in their lymphocyte profiles after receiving radiotherapy, with or without chemotherapy. The study will involve collecting fresh tumor biopsies and evaluating the patients' overall health and organ function prior to enrollment.

Why it matters

Who can join: the full rules

Inclusion Criteria:

Age at least 18 years. ECOG PS 0-1. Pathologically confirmed NSCLC, esophageal squamous cell carcinoma or thymic epithelial tumor.

Life expectancy of more than 3 months. Patients with no indications for palliative radiotherapy in the opinion of the investigator.

Patients with a prior history of surgery are eligible if they have recovered adequately from the toxicity and/or complications of surgery.

Signed informed consent for the use of fresh tumor biopsies before and during the treatment.

Women of childbearing age and men must agree to use effective contraception during the trial.

Adequate organ function within 1 week prior to the enrollment：

1. Adequate bone marrow function: hemoglobin ≥80g/L, white blood cell (WBC) count ≥ 4.0 \* 10 \^ 9/L or neutrophil count ≥ 1.5 \* 10 \^ 9/L, and platelet count ≥ 100 \* 10 \^ 9/L;
2. Adequate hepatic function: total bilirubin \< 1.5 x upper limit of normal (ULN). Note: If total bilirubin is \> 1.5 x ULN, direct bilirubin must ≤ ULN, Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) ≤2.5 ULN;
3. Adequate renal function: serum creatinine ≤ 1.5 x ULN or creatinine clearance ≥ 50 mL/min;

Exclusion Criteria:

Pregnant or lactating women. History of any other malignancy. Patients in whom palliative radiotherapy is indicated in the opinion of the investigator.

Patients who have received tumor vaccine; or administration of live, attenuated vaccine within 4 weeks before the start of treatment.

Mental disorders, drug abuse, and social condition that may negatively impact compliance in the opinion of the investigator.
