About

Background: Gastric-type endocervical adenocarcinoma (G-EAC) is a new classification of cervical mucinous carcinoma. G-EAC is a unique human papillomavirus unrelated adenocarcinoma that can be distinguished from typical endocervical adenocarcinoma (UEA). In China, adjuvant therapy for cervical cancer after surgery includes not only radiotherapy (RT) or concurrent chemoradiotherapy (CCRT), but also chemotherapy in many cases. However, no previous prospective study has analyzed the adjuvant therapy of G-EAC. This study is the first randomized phase III trial, which aims to recommend better adjuvant treatment options for G-EAC patients at high risk of recurrence in China, in order to better optimize and personalize patient care and improve recurrence-free survival and overall survival.

Methods: This trial is a prospective, multicenter study led by the Department of Radiotherapy, Affiliated Hospital of Obstetrics and Gynecology, Zhejiang University. Recruitment will begin in February 2025, and it is expected that 238 patients with postoperative cervical gastric adenocarcinoma with high risk of recurrence will be recruited from 16 clinical centers in China. Patients will be randomly assigned to the experimental group or the control group in a 1:1 ratio. The experimental group will receive paclitaxel combined with platinum-based concurrent chemoradiotherapy and short-term adjuvant chemotherapy, and the control group will receive the current standard treatment regimen, i.e., platinum-based concurrent chemoradiotherapy, without adjuvant chemotherapy. The primary endpoint of the study is the 2-year progression-free survival, and the secondary endpoints are disease treatment failure pattern, overall survival rate, acute/chronic toxicity incidence, and quality of life assessment.

Inclusion criteria

  1. Pathologically confirmed Gastric-type endocervical adenocarcinoma;

  2. Based on standard examination procedures, it is determined that one of the following risk factors is combined: positive margin, positive paracervical involvement, adnexal involvement, positive lymph nodes, tumor diameter ≥ 4cm, infiltration of the outer 1/3 of the cervical stroma, and vascular tumor thrombus. The specific inclusion can be discussed by two senior clinical doctors;

  3. Medical history inquiry and gynecological examination must be performed within 14 days before enrollment to confirm the size of the tumor and International Federation of Gynecology and Obstetrics (FIGO) stage;

  4. Chest Computed Tomography (CT) plain scan, abdominal enhanced CT scan, or Positron Emission Tomography (PET)/CT examination within 30 days before enrollment;

  5. Pelvic CT, Magnetic Resonance Imaging (MRI) or PET/CT examination within 30 days before enrollment;

  6. General condition score 0-1 points;

  7. Age 18-65 years old;

  8. Laboratory examinations must be performed within 14 days before enrollment, and bone marrow, liver function, and kidney function tests are performed:

    1. White blood cell (WBC) ≥ 3.5 x 10E9/L (normal range)
    2. Neutrophils ≥ 1.5 x 10E9/L;
    3. Platelets ≥ 100 x 10E9/L;
    4. Hemoglobin ≥ 100 g/L (transfusion or other methods are acceptable)
    5. Liver function is within the normal range: alanine aminotransferase (ALT), aspartate aminotransferase (AST) < 1.5 times the upper limit of normal, alkaline phosphatase (ALP) < 2.5 times the upper limit of normal, bilirubin < upper limit of normal.
    6. Renal function is within the normal range: creatinine clearance rate (CCr) > 60 ml/min.

Calculation formula: CCr=(140-age)×weight (kg)/[72×Scr (mg/dl)] or CCr=[(140-age)×weight (kg)]/[0.818×Scr (umol/L)] g) International prothrombin ratio (INR) ≤ 1.5 9. Women of childbearing age must agree to take effective contraceptive measures during the entire treatment study; 10. Patients must sign an informed consent form before enrollment;

Exclusion criteria

  1. Pathological types of non-gastric adenocarcinomas such as squamous cell carcinoma, adenosquamous carcinoma, undifferentiated carcinoma, small cell carcinoma, neuroendocrine carcinoma, and sarcoma of cervical cancer;
  2. Stage IVB;
  3. Previous invasive malignant tumors: excluding non-malignant melanoma skin cancer;
  4. Systemic chemotherapy in the past 3 years;
  5. Previous history of pelvic or abdominal radiotherapy, which may cause overlap of irradiation field for this radiotherapy;
  6. Distant metastatic lesions in other organs;
  7. The following serious active concurrent diseases:
  1. Unstable angina and/or congestive heart failure requiring hospitalization in the past 6 months 2) Transmural myocardial infarction in the past 6 months 3) Acute bacterial or fungal infection requiring intravenous antibiotic treatment at the time of registration 4) Exacerbation of chronic obstructive pulmonary disease or other respiratory diseases requiring hospitalization or hindering the study 5) Jaundice or coagulation disorder caused by poor liver function 6) Acquired immunodeficiency disease (Patients diagnosed with Acquired Immune Deficiency Syndrome (AIDS), or patients suspected of having AIDS who refuse HIV testing); 7) Other immunocompromised states (e.g. organ transplantation, long-term use of glucocorticoids); 8. Pregnant women, breastfeeding women.
