About this study

Official title: A Multicenter Randomized Controlled Trial of the Efficacy of Postoperative Radiotherapy for Atypical Meningioma Without Venous Sinus Invasion After Gross-total Resection

Postoperative adjuvant radiotherapy is a key component of comprehensive treatment of meningioma. However, for atypical meningioma after total resection, there is still a huge controversy in patients who need adjuvant radiotherapy after surgery.

Many scholars have focused on this problem and carried out some small-scale retrospective studies, but they have contradictory results. Some of the studies found that postoperative adjuvant radiotherapy could not improve the prognosis of patients, but was questioned because the sample size was too small, resulting in insignificant results, while other studies found that postoperative adjuvant radiotherapy can improve progression free survival. A study based on the National Cancer Database found that postoperative adjuvant radiotherapy and gross tumor resection are associated with a good prognosis. A recent meta-analysis enrolled a total of 757 patients and found that postoperative adjuvant radiotherapy reduced the risk of tumor recurrence but did not improve survival time. Our team reviewed the meningioma data in the SEER database and conducted a study previously. The study found that postoperative adjuvant radiotherapy did not improve the overall survival of these patients. The relevant research results were recently published in Frontiers in oncology. We further reviewed and summarized the single-center data of our hospital and found that postoperative adjuvant radiotherapy could not improve the progression free survival and overall survival of patients. Besides, we also performed a meta-analysis and found that postoperative adjuvant radiotherapy had a trend to improve progression-free survival, but there was no statistical difference.

Because there are many deficiencies in previous researches, and the research results are also contradictory, it is still unclear whether patients with atypical meningioma who have undergone gross total resection can benefit from postoperative adjuvant radiotherapy. Further high quality clinical trials is still needed to be conducted in order to guide the postoperative care of patients. Therefore, we intend to conduct this multicenter randomized controlled trial to determine the value of postoperative adjuvant radiotherapy in patients with atypical meningioma who underwent gross total resection.

Read the detailed description

The study aims to enroll a total of 140 participants. Subjects would be enrolled with the following information: name, age, gender, contact, KPS score, preoperative ASA score, current ECOG score, tumor location, date of surgery, degree of tumor resection (modified Simpson grade), pathology type, Ki-67 Proliferation index, etc. The preoperative magnetic resonance image of the subject is stored. Tissue specimens are genetically examined.

Using a simple randomization method and random assignment in a 1:1 ratio, a random sequence was first generated, and SAS version 9.1 statistical software was used to generate an allocation sequence table including subject numbers, 140 random numbers, and random groupings. 140 Subjects would be assigned to the test group (n=70) and the control group (n=70) in a 1:1 ratio. The table of the assignment sequence is duplicated and saved by the neurosurgical secretary and the trial designer of the Second Affiliated Hospital of Zhejiang University. The secretary puts the group mark into the 140 opaque kraft envelopes with the serial number 1 to 140 according to the order of the allocation sequence table, and submits them to the test designer. Zhige Guo is responsible for enrolling the participants according to the inclusion criteria, assigning the subjects numbers according to the order of the treatment, and Qiang Zeng is responsible for disassembling the corresponding opaque envelopes according to the number of the subjects, and exerting interventions according to the group marks. Chenhan Ling is responsible for follow-up and regular measurement of various indicators, and Fei Dong is responsible for the images reports. Until the end of the trial, Zhige Guo, Chenhan Ling and Fei Dong would not know the grouping of the subjects.

The test level of the study was α=0.05, and the two-sided test was used. All statistical analysis was performed by SPSS 16.0 statistical software.

  1. For PFS, OS, and DSS data, the COX proportional hazards model was used to calculate the hazard ratio (HR) of radiotherapy and to assess the statistical difference between the corresponding prognostic data between the two groups.
  2. For the 3-year progression-free survival, 3-year survival rate, and 5-year progression-free survival, 5-year survival rate data, the chi-square test was used to compare the differences between the two groups.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression-free survival

    the length of time during and after medication or treatment during which the disease being treated does not get worse

    Measured: 60months

Secondary outcomes (7)
  1. 3-year survival rate

    the percentage of people in a study or treatment group still alive for 3 years after diagnosis

    Measured: 36months

  2. 3-year progression-free survival

    3 years during and after medication or treatment during which the disease being treated does not get worse

    Measured: 36months

  3. 5-year survival rate

    the percentage of people in a study or treatment group still alive for 5 years after diagnosis

    Measured: 60months

  4. 10-year progression-free survival

    10 years during and after medication or treatment during which the disease being treated does not get worse

    Measured: 120 months

  5. 10-year survival rate

    the percentage of people in a study or treatment group still alive for 10 years after diagnosis

    Measured: 120 months

  6. Disease-specific survival

    the percentage of people in a study or treatment group who have not died from a specific disease in a defined period of time. The time period usually begins at the time of diagnosis or at the start of treatment and ends at the time of death. Patients who died from causes other than the disease being studied are not counted in this measurement

    Measured: from diagnosis up to 10 years

  7. overall survival

    From randomization to death due to any cause

    Measured: from diagnosis up to 10 years
