Etoposide/Cisplatin Compared With Irinotecan/Cisplatin for Advanced Gastrointestinal Neuroendocrine Tumor G3 Type

This is an interventional treatment trial for Gastrointestinal Neuroendocrine Tumor Read More

Inclusion Criteria:

• 1. 18-75 years old, male or female. 2. Confirmed non-primary pancreatic metastatic and/or unresectable gastrointestinal neuroendocrine tumor G3 type patients by histopathological and imaging examinations.

  3. ECOG performance status 0-1. 4. Life expectancy ≥ 12 weeks. 5. A histological specimen can be provided for secondary testing. 6. According to the evaluation criteria of solid tumor efficacy (RESIST 1.1), there should be at least one measurable lesion (empty organs such as esophagus and stomach cannot be taken as the measurable lesion), and the measurable lesion should not have received local treatment such as radiotherapy (the lesion located in the previous radiotherapy area is also selected as the target lesion if the lesion progression is confirmed).

  7. Never received system treatment before, including cytotoxic drugs. For patients who have received adjuvant or neoadjuvant chemotherapy appears recurrence or metastasis more than 6 months from accepting the last dose of chemotherapy drugs can be screened.

  8. The main organ function meets the following criteria within 7 days before treatment:

  1. Blood routine examination criteria (without blood transfusion within 14 days): hemoglobin (HB) ≥ 90g/L, the absolute value of neutrophils (ANC) ≥ 1.5 x 10^9/L, platelet (PLT) ≥ 80 x 10^9/L.
  2. Biochemical examinations must meet the following criteria: total bilirubin (TBIL) ≤ 1.5 x upper limit of normal (ULN), alanine aminotransferase (ALT), aspartate aminotransferase (AST) ≤ 2.5 x ULN, serum creatinine (Cr) ≤ 1.5 x ULN or creatinine clearance (CCR) ≥ 60 mL/min.
  3. Doppler ultrasound assessment: left ventricular ejection fraction (LVEF) ≥ normal low limit (50%).

  9. Fertile men and women must use effective contraception during the study period and within 6 months after the end of the study.

  10. Volunteered to participate in the study and signed an informed consent form.

Exclusion Criteria:

• 1.Patients exceeding or currently suffering from other malignant tumors within 5 years, except for cervical cancer in site, non-melanoma skin cancer and superficial bladder tumors (Ta (non-invasive tumor), Tis (in situ carcinoma), and T1 (tumor infiltrating basement membrane)); Patients with rapid progress within 3 months.

  2. History of gastrointestinal perforation and/or fistula within 6 months prior to the first administration.

  3. Patients who had received radiotherapy for tumor target lesions within 4 weeks before enrollment.

  4. History of immunodeficiency disease, including HIV positive and other acquired or congenital immunodeficiency diseases.

  5. Allergic reactions and drug adverse reactions:

  1. A history of allergy to the ingredients of the study drug;
  2. Any contraindication to any study drug (etoposide, irinotecan and cis-platinum) in the chemotherapy regimen.

  6. Significantly malnourished patients. Exclusion is performed if the patient is receiving intravenous fluids or is required to be hospitalized for continuous infusion therapy. Patients with good nutrition control ≥ 28 days can be enrolled before randomization.

  7. Any severe and/or uncontrolled disease, including:

  1. Patients with hypertension whose blood can't be well controlled by antihypertensive drugs (systolic blood pressure ≥ 150 mmHg, diastolic blood pressure ≥ 100 mmHg).
  2. Grade 1 or higher myocardial ischemia or myocardial infarction, arrhythmia (including QTc ≥ 480 ms) or grade 2 and above congestive heart failure according to New York Heart Association (MYHA) classification.
  3. Severe or uncontrolled disease or active infection (≥ CTC AE grade 2), which the investigators believe may increase the risk associated with patient participation and drug administration.
  4. Renal failure requiring hemodialysis or peritoneal dialysis.
  5. Patients of diabetes who have poor glycemic control (fasting blood glucose (FBG) > 10 mmol/L).
  6. Patients of seizures requiring treatment. 8. Patients with gastrointestinal disease such as intestinal obstruction (including incomplete intestinal obstruction) or those who may meet gastrointestinal bleeding, perforation obstruction.

  9. Patients who underwent surgical treatment, incision biopsy or significant traumatic injury within 28 days prior to enrollment.

  10. Any bleeding event ≥ CTC AE grade 3 or unhealed wounds, ulcers or fractures in 4 weeks prior to enrollment.

  11. Arterial/venous thrombosis events within 3 months, such as cerebrovascular accidents (including transient ischemic attacks), deep venous thrombosis and pulmonary embolism.

  12. Patients who prepared or accepted previously allogeneic organ or bone marrow transplantation, including liver transplantation.

  13. Concomitant disease that seriously harms the patient's safety or affects the patient's completion of the study according to the investigator's judgment.

  14. Patients cannot provide histological specimens for secondary test. 15. Patients who have a history of psychotropic substance abuse and are unable to quit or have a mental disorder.

  16. Urine routine showed urinary protein ≥ 2 + and 24-hour urine protein quantitation > 1.0 g.

  17. Patients with brain metastases. 18. Patients who have participated in other anti-tumor drug clinical trials within 4 weeks.
