Clinical Trial Summary

To observe the effect and toxicity of carbon ion radiotherapy on local advanced non-small cell lung cancer over 75 years old patients. Systemic therapy could be targeted therapy, chemotherapy or immunotherapy.

Description:

The patient will receive carbon ion radiotherapy with 70Gy per 20 fractions. Patients with genetic mutations (including but not limited to EGFR, ALK, etc.) should receive targeted therapy as their systemic therapy. For patients who are not suitable for targeted therapy, we recommend single regimen chemotherapy in sequence with radiotherapy. The drugs include etoposide, platinum (carboplatin, cisplatin, nedaplatin or loplatin), vinorelbine, paclitaxel (including liposome paclitaxel and albumin paclitaxel), docetaxel, pemetrexel, gemcitabine, etc. If there is no contraindication to PD-1/PD-L1 immunotherapy, it can be combined with immunotherapy, such as Pembrolizumab. For patients who cannot tolerate chemotherapy, PD-1/PD-L1 immunotherapy is recommended. The progression-free survival rate, toxicity, local control rate, cause-specific survival rate and overall survival rate were observed with regular follow-up after treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Disease progression-free survival rate	Disease progression-free survival rate was defined from the start of carbon ion radiotherapy till the date of disease progression at any site or death, or the last follow up.	From date of radiotherapy started until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 100 months.
Primary	Incidence of Treatment-induced Adverse Events	Treatment-induced toxicities were scored using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, for events observed after the first dose of irradiation. Toxicities occurred 90 or more days after the completion of CIRT were defined as late toxicities.	From date of radiotherapy started, every 3-4 months within the first 2 years, every 6 months between years 3 and 5, and annually thereafter, assessed up to 100 months.
Secondary	Local control rate	Local control rate was defined from the start of carbon ion radiotherapy till the date of local failure or the last follow-up	From date of radiotherapy started until the date of first documented local disease progression, assessed up to 100 months.
Secondary	Cause-specific survival rate	Cause-specific survival rate was defined from the start of carbon ion radiotherapy till the date of death caused by non-small cell lung cancer treated in this study or the last follow-up	From date of radiotherapy started until the date of first documented death caused by non-small cell lung cancer treated in this study, assessed up to 100 months.
Secondary	Overall survival rate	Overall survival rate was defined from the start of carbon ion radiotherapy till the date of death or the last follow-up.	From date of radiotherapy started until the date of death from any cause, assessed up to 100 months.
