About this study

Official title: A Prospective Multicenter Randomized Controlled Trial of the Clinical Efficacy of Neoadjuvant Therapy Based on Organoids Drug Sensitivity Versus Empirical Neoadjuvant Therapy in the Treatment of Advanced Rectal Cancer

This is a prospective multicenter randomized controlled trial study. According to the enrollment criteria, patients with locally advanced rectal cancer who need neoadjuvant therapy before radical surgery were randomly divided into the organoids drug sensitivity group and the standard whole-course neoadjuvant therapy group. The Organoids drug sensitivity group was treated with personalized neoadjuvant therapy under the guidance of tumor organoids drug sensitivity technology combined with standard long-term radiotherapy. The standard whole-course neoadjuvant therapy group was treated with neoadjuvant simultaneous radiotherapy and chemotherapy (Total Neoadjuvant Therapy, TNT) based on guidelines and clinical experience. The tumor pathological complete remission rate (pCR), postoperative complication rate, postoperative tumor withdrawal grade, postoperative recurrence rate, treatment tolerance rate, R0 resection rate, and sphincter preservation rate were observed and compared.

Read the detailed description

Based on the need for individualized treatment in the era of precision medicine, an in vitro model that can accurately predict the response of patients to treatment is urgently needed, so that suitable patients can receive effective treatment and patients whose treatments are ineffective can avoid adverse reactions. The emergence of tumor organoids technology makes this vision possible.

Tumor-organoid (Patient-Derived Organoids, PDOs) is a kind of micro-organ with a three-dimensional structure, which is cultivated in the environment of 3D matrix glue in vitro. Based on the individualized neoadjuvant therapy based on the drug sensitivity technology of tumor-organoid, the best neoadjuvant therapy can be selected and the clinical efficacy and drug tolerance can be quickly predicted, which is of great significance in the field of accurate tumor therapy. The preliminary study of our group also completed the organ-like library of more than 100 patients with local advanced rectal cancer. It was proved that the organoids of the organoids library had high homology with the original tumor tissue, and the detection period of drug sensitivity of organoids was less than 2 weeks, which was much less than 2 months of PDX drug sensitivity technology in mice, which did not affect the time window of clinical drug treatment, and the results of drug sensitivity were basically consistent with the clinical efficacy.

Therefore, we have reason to believe that tumor organoids chemosensitivity technology, as an economical, high-throughput, and efficient technology for tumor research, is expected to play an important role in clinical individualized treatment of tumors.

Our previous study found that tumor-based organoids drug sensitivity technology can be used as an effective and reliable clinical assistant tool to guide and assist doctors to formulate the best treatment strategy for tumor patients. Personalized neoadjuvant therapy has better clinical efficacy than standard whole-course neoadjuvant therapy.

Therefore, in this study, through a prospective, multicenter, multi-arm umbrella clinical study, patients with locally advanced rectal cancer who need neoadjuvant therapy are randomly divided into two groups: the organoids drug sensitivity group and the standard whole-course neoadjuvant therapy group. To compare the clinical efficacy of personalized neoadjuvant therapy based on tumor organoids chemosensitivity combined with standard long-term radiotherapy with the clinical efficacy of standard whole-course neoadjuvant therapy in locally advanced rectal cancer. This technology can be used in the clinical use of advanced rectal cancer new auxiliary decision-making system so that the standardization of comprehensive treatment of rectal cancer can be implemented in China, which is of great significance for the development of the national economy and the improvement of medical level in China.

What is being measured

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

  1. Pathologic Complete Response

    Neoadjuvant therapy and postoperative pathology confirmed that the primary tumor was in complete remission (stage ypT0) and had no residual tumor cells, regardless of whether the regional lymph nodes were involved or not.

    Measured: 3 years

Secondary outcomes (7)
  1. Postoperative complication

    Intra-abdominal bleeding, anastomotic leakage, intra-abdominal infection, intestinal obstruction, postoperative diarrhea, wound infection, pulmonary infection, cardiovascular accident, cerebrovascular accident, etc.

    Measured: 3 years

  2. Tumor Regression Grading

    Tumor pathological reaction is graded after neoadjuvant therapy, usually according to the proportion of fibrosis and residual tumor in the tumor.

    The analytical system for evaluating treatment response recommended by NCCN is as follows: complete response-no living cancer cell residue, moderate reaction-single or small cluster cancer cell residue,mild reaction-residual cancer focus, interstitial fibrosi,adverse reaction-few or no cancer cell regression.

    Measured: 3 years

  3. Local recurrence

    Recurrence occurs in the surgical area, with or without the rise of tumor markers. The tumor found in the anastomosis needs to be confirmed by pathological biopsy.

    Measured: 3 years

  4. Distant metastasis

    CT or MRI or radionuclide scan can detect metastases in liver, lung and bone, with or without confirmed by pathology.

    Measured: 3 years

  5. Treatment tolerance rate

    To evaluate the tolerance and completion of preoperative neoadjuvant therapy.

    Measured: 3 years

  6. R0 resection rate

    R0 resection rate of laparoscopic radical surgery for rectal cancer after neoadjuvant therapy.

    Measured: 3 years

  7. anus-saving rate

    anus-saving rate after radical resection of rectal cancer after neoadjuvant therapy

    Measured: 3 years
