Clinical Study of Postoperative Carbon Ion Radiotherapy for Thymus Tumor With Residual Tumor
NCT ID:
NCT06311955
Condition:
Thymic Epithelial Tumor
Radiotherapy Side Effect
Carbon Ion Radiotheray
Heavy Ion Radiotherapy
Study type:
Interventional
Study phase:
Phase 2
Overall status:
Recruiting
Study design:
Allocation:
N/A
Intervention model:
Single Group Assignment
Primary purpose:
Treatment
Masking:
None (Open Label)
Intervention:
Intervention type:
Radiation
Intervention name:
Carbon ion radiotherapy
Description:
The patients will receive 72GyE per 18 fractions of carbon ion radiotherapy. Patients
with thymus cancer should be combined with platinum-based regimen (including etoposide
combined with cisplatin / carboplatin / loplatin / nedaplatin; paclitaxel combined with
cisplatin or cisplatin / carboplatin / loplatin / nedaplatin; docetaxel combined with
cisplatin / carboplatin / loplatin / nedaplatin) for at least 4 cycles. The primary
endpoint was progression-free survival and toxicities, and the secondary endpoint was
local relapse-free survival, overall survival and cause-specific survival.

Summary:
To observe the efficacy and toxicities of heavy ion radiation therapy for locally
advanced or advanced primary thymic epithelial malignant tumor received R2 resection. The
primary endpoint was progression-free survival and toxicities, and the secondary endpoint
was local relapse-free survival, overall survival and cause-specific survival.

Criteria for eligibility:
Criteria:
Inclusion Criteria:
- Patients with stage II-IV (Masaoka-Koga) thymus epithelial malignancies without a
history of thoracic radiotherapy who had undergone radical surgery (R2 resection,
visible residual tumor) and had a definite pathological diagnosis.
- Sign informed consent.
- Between the ages of 18 and 70.
- ECOG general status score of 0-2.
- The expected survival is at least 6 months.
- Adequate organ function: 1). Blood function: absolute neutrophil count (ANC) ≥1.5 x
109/L, platelet count ≥80 x 109/L, hemoglobin ≥9 g/dL 2). Lung function: FEV1>25%,
DLCO>25% 3). Cardiac function: no serious pulmonary hypertension, cardiovascular and
cerebrovascular diseases, peripheral vascular diseases, serious chronic heart
disease and other complications that may affect radiotherapy.4). Adequate liver
function: total bilirubin <1.5 times the upper limit of normal value, and AST, ALT<2
times the upper limit of normal value. 5). Adequate renal function: serum creatinine
≤1.5 times the upper limit of normal or calculated creatinine clearance ≥50 ml /min,
and urinary protein <2+. Patients with a baseline urinary protein level of 2+ or
more should have a 24-hour urine collection and evidence of a 24-hour urinary
protein level of 1g or less.
Exclusion Criteria:
- Complicated with other malignant tumors that have not been controlled.
- Have large quantity of pleural or pericardial effusion.
- Patient whose particle radiotherapy plan cannot meet the minimum target dose
coverage and dose volume limitation requirements, or cannot meet the dose constrains
of normal tissue or organs.
- Chest radiation therapy or radioactive particle implantation history.
- Cardiac pacemakers or other internal metal prosthesis implants that may be affected
by high-energy radiation or may affect the dose distribution to the radiation target
area.
- Pregnancy (confirmed by serum or urine β-HCG test) or lactation period.
- HIV positive. Hepatitis virus replication phase, need to receive antiviral therapy,
but because of concomitant disease cannot receive antiviral therapy. Active stage of
syphilis.
- A history of mental illness may hinder the completion of treatment.
- With serious comorbidity that may interfere with radiotherapy, including: (a) Acute
infectious diseases or acute active phase of chronic infection. b) Unstable angina
pectoris, congestive heart failure, myocardial infarction that has been hospitalized
in the past 6 months. c) Exacerbations of chronic obstructive pulmonary disease or
other respiratory conditions requiring hospitalization. d) Severely impaired immune
function. e) Diseases with excessive sensitivity to radiation such as ataxia
telangiectasia. f) Other diseases that may affect particle radiotherapy.
- Other circumstances that the physician considers inappropriate to participate in
clinical study.
