Brief Summary:
A pre-metastatic target organprimary lesion fusion radiomics model was developed based on the soil-seed theory to predict comman tumor metastasis in retrospective settings To prospectively verify the performance of the target organprimary lesion fusion radiomics model in predicting tumor metastasis patterns brain metastasis in lung cancer liver metastasis in colorectal cancer lung metastasis in breast cancer we designed this prospective observational trial
Detailed Description:
Metastasis is an important biological feature of malignant tumors and it is also the main factor affecting the outcome of cancer patients The direct death of most cancer patients is the mass effect of metastatic lesions or the loss of metastatic target organ function Therefore it has become one of the urgent and arduous tasks in the field of oncology to explore the pathophysiological mechanism of malignant tumor metastasis and find new targets to form new methods for the early diagnosis and treatment of tumor metastasis
Tumor metastasis is a continuous and gradual process Tumor cells in the primary tumor proliferated tumor cells shed from the primary tumor invaded the basement membrane invaded blood vessels lymphatic vessels or body cavity and migrated to another site or organ with the blood flow and lymph flow Tumor cells adhered to the capillaries of the target organ penetrated the blood vessels to form micrometastases cell proliferation and produced new blood vessels and formed secondary tumors of the same type as the primary tumor They can invade and metastasize again In the process of metastasis gene mutations and subsequent changes in the immunogenicity of tumor cells promote the formation of local tumor tissue inhibitory microenvironment which suppresses the host immune system and leads to tumor metastasis
Previous studies have found that tumor metastasis has Organ specificity called Organ-tropism That is different types of tumors tend to metastasize to different organs For example lung cancer often metastasizes to the brain colorectal cancer and pancreatic cancer commonly metastasize to the liver breast cancer and prostate cancer commonly metastasize to the bone and so on Therefore Stephen Paget a British pathologist put forward and elaborated his seed and soil theory more than a hundred years ago advocating that metastasis requires the spread of tumor cells that is seeds and the ideal environment for receiving organs that is fertile soil He proposed in this theory that successful metastasis to distant organs requires not only tumor cells with metastatic potential seeds but also a suitable host organ soil During tumor progression the composition and phenotypic types of immune cells in the tumor microenvironment are shaped by both malignant cells and the niche of adjacent tissues Metastatic tumors seeds will retain genetic characteristics when they are transferred to different organ-specific tissue environments soil It is not enough for tumor cells to reach a certain organ tissue but also requires the coordination between tumor cells seeds and organ microenvironment soil to plant and grow in a suitable environment soil and become metastatic foci In the seed and soil theory the intrinsic characteristics of seeds have been proved to affect various key transfer processes On the other hand few studies have focused on the relationship between the intrinsic characteristics of soil target organ and the formation of malignant tumor metastasis one of the main reasons is that it is often not ethical to conduct invasive research on the target organ of patients without metastasis
Radiomics is an emerging field which develops new biomarkers through quantitative analysis of imaging examination images of patients which can study and analyze the potential pathophysiological characteristics of regions of interest in a non-invasive way Previous studies have shown that radiomics studies of seeds primary tumors can predict metastasis of many malignant tumors which establishes radiomics evidence for the seed and soil theory from the perspective of seeds However radiomics studies from the perspective of soil the target organ for metastasis are rare Taking the brain metastases of lung cancer as an example most existing radiomics studies using brain imaging information only evaluate the regions where brain metastases have occurred Considering that radiomics can also extract biological features from target organs that have not yet metastasized our group has found that radiomics analysis of pretreatment brain MRI images of lung cancer patients without baseline brain metastasis can effectively predict the probability of brain metastasis in a certain period of time This study also revealed for the first time that the target organ without metastasis soil also plays a key role in the occurrence of malignant tumor metastasis
The results of this study also suggest that the malignancy prediction model derived from radiomics could be a promising tool for screening patients at high risk of tumor metastasis Integrated risk prediction models that take into account seed and soil characteristics may help guide clinical practice eg more rigorous monitoring of high-risk patients or the use of more intensive systemic treatment
In conclusion it is necessary to further explore the applicability of this seed and soil theory-based radiomics model for cancer prediction to verify its universality and clinical application prospects In this study we will collect imaging information of patients baseline primary lesions and potential metastatic target organs in a variety of common tumors lung cancer colorectal cancer breast cancer etc To explore the performance of the seed and soil radiomics model in predicting cancer metastasis patterns brain metastasis of lung cancer liver metastasis of colorectal cancer lung metastasis of breast cancer in order to establish a non-invasive cost-effective and effective radiomics prediction model for distinguishing high risk and low risk cancer metastasis in corresponding cancer types To provide a theoretical basis for the further formation of individualized diagnosis and treatment standards for patients with malignant tumors
