Lung Cancer Recurrence Risk Assessment

Product introduction

Problem solved

Molecular profiling of transcriptomic multigene expression and recurrence risk assessment is implemented in the lung cancer patients and used to guide individualized treatment protocols and to inform physicians in developing treatment plans and strategies.

Group patients by 4 features
  1. For the use of chemotherapy or not;
  2. Normal and abnormal expression subtypes of gene clusters for nine driver genes of lung cancer, namely ALK, BRAF, EGFR, MET, NTRK, RAS, RET, ROS1, TP53, and two immunotherapy target genes, PDCD1 and CTLA4;
  3. For different pathological subpopulations, such as those with different stages (Stage I, Stage II-IV);
  4. For different age groups, e.g. <=65 years or >65 years.
Recurrence risk assessment model

The recurrence model accurately classifies cancer patients into about 33,000 combinations based on 4 features taken from the population. Using big data AI algorithms, corresponding to each feature taken, we developed 30 recurrence risk assessment models for different populations for research, and for each patient, personalized matching 15 recurrence models, resulting in 15 recurrence scores, comprehensive recurrence risk, and finally recommending 1 personalized treatment plan.

Treatment protocol recommendation
  1. To determine whether or not to have chemotherapy:
    1. a. The risk of recurrence is divided into low, medium and high risk groups.
    2. b. Low-risk groups do not require chemotherapy; medium- to high-risk groups require chemotherapy; and high-risk groups require more aggressive treatment.
  2. To guide targeted drug usage (further clinical validation required):
    1. a. For people at high risk of abnormal expression of the driver gene cluster: try the targeted drug corresponding to that gene.
    2. b. For people at high risk of abnormal expression of the immune gene cluster: try the immunotherapy corresponding to that gene.
