Lead Sponsor:

Fudan University

Conditions:

Small Cell Lung Cancer Extensive Stage

Eligibility:

All Genders

18+ years

Phase:

PHASE1

Brief Summary

This study intends to recruit ES-SCLC patients with response to standard first-line chemo-immunotherapy to assess the safety of receiving different doses of consolidative thoracic radiotherapy.

Detailed Description

Approximately two-thirds of Small-cell lung cancer (SCLC) patients are in the extensive stage (Extensive-Stage SCLC, ES-SCLC) at the time of diagnosis, and the 5-year survival rate of these patients i...

Eligibility Criteria

Inclusion

  • Inclusion criteria:
  • age ≥ 18 years;
  • ECOG performance status score 0-2 points;
  • pathologically confirmed small cell lung cancer;
  • complete baseline imaging data (including brain enhanced MRI/CT, PET-CT or chest enhanced CT + bone scan + neck and abdominal B ultrasound/CT) before first-line treatment;
  • stage extensive-stage SCLC at initial diagnosis, and first-line treatment received standard platinum-based doublet chemotherapy combined with immunotherapy (PD-1 or PD-L1) for at least 4 cycles after the efficacy assessment of SD or PR (residual lesions assessed by chest CT);
  • no history of other malignancies;
  • reproductive age male/female agreed to contraception during the trial (surgical ligation or oral contraceptives/intrauterine devices + condom contraception);
  • life expectancy ≥ 3 months
  • 1 week before enrollment, the investigator judged that the patient could continue immune maintenance therapy at the same time, And the organ function level meets the following criteria:
  • 1\) bone marrow function: hemoglobin ≥ 80 g/L, white blood cell count ≥ 4.0 \* 10 \^ 9/L or neutrophil count ≥ 1.5 \* 10 \^ 9/L, platelet count ≥ 100 \* 10 \^ 9/L; 2) liver: serum total bilirubin level ≤ 1.5 times the upper limit of normal, when serum total bilirubin level \> 1.5 times the upper limit of normal direct bilirubin level must be ≤ the upper limit of normal,Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 times of the upper limit of normal; serum albumin ≥ 27 g/L; 3) Kidney: serum creatinine level \< 1.5 times of the upper limit of normal or creatinine clearance ≥ 50 ml/min, urea nitrogen ≤ 200 mg/L; 10.Patients must have the ability to understand and voluntarily sign an informed consent form.

Exclusion

  • baseline pathological examination found mixed with non-small cell lung cancer components;
  • patients who had used any anti-tumor therapy before the diagnosis of ES-SCLC;
  • patients who had received anti-tumor therapy other than standard chemotherapy + immunotherapy regimen;
  • patients who had PD assessed by chemotherapy combined with immunotherapy efficacy;
  • patients who had no residual thoracic lesions (lung, mediastinal and supraclavicular metastatic lymph nodes, thoracic efficacy CR) on chest enhanced CT during efficacy assessment;
  • patients with severe immune-related toxicities after treatment;
  • symptomatic interstitial lung disease or active infection/non-infectious pneumonia;
  • patients who required long-term use of cortisol or immunosuppressive agents;
  • allergic to PD-1 or PD-L1 monoclonal antibody immunotherapy or other causes of inability to perform immune maintenance therapy;
  • lactating or pregnant women;
  • patients with severe autoimmune diseases: active inflammatory bowel disease (including Crohn 's disease, ulcerative colitis), rheumatoid arthritis, scleroderma, systemic lupus erythematosus, autoimmune vasculitis (such as Wegener' s granulomatosis), etc.;
  • researchers believe that physical examination or clinical trials may interfere with the results or increase the risk of treatment complications, or other uncontrollable diseases;
  • patients with mental illness, substance abuse, social problems affecting compliance are not enrolled after the doctor 's review.
