Problems solved by technology

Radiotherapy and chemotherapy can reach all parts of the body and can also treat some metastatic tumors. However, because radiotherapy and chemotherapy are administered systemically, they have relatively large toxic and side effects on healthy cells and tissues.
3. Antibody therapy, using antibodies to specifically block immune checkpoints related to tumor growth, such as PD-1 molecules, to initiate the body’s anti-tumor immune response process to achieve anti-tumor effects. Although this method is effective, there are The diversity of antigenic epitopes has brought about certain limitations such as low overall effectiveness and difficulty for drugs to break through the blood-brain barrier and tumor microenvironment
However, the common challenge of current targeted tumor therapy is the lack of effective biomarkers, and the evaluation of the efficacy of new targeted drugs needs to be combined with the exploration of biomarkers in future clinical trials

Abstract

The invention discloses a composition for combined treatment of solid tumors, and the effective component at least includes an mmp3 antagonistic substance and an oncolytic virus. The composition usesthe mmp3 antagonistic substance and the oncolytic virus to perform combined treatment on the solid tumors, and can effectively inhibit tumor growth and improve survival rate.

Description

technical field [0001] The invention belongs to the technical field of cancer treatment, and in particular relates to a combined treatment composition for solid tumors. Background technique [0002] Cancer is a kind of disease that seriously endangers public health. According to statistics, in 2018, there were 18.1 million new cancer patients and 9.6 million deaths worldwide. Therefore, exploring new and effective cancer treatments is one of the current global research hotspots. [0003] At present, there are mainly the following methods for tumor treatment: 1. Surgical treatment. Surgical treatment can quickly and accurately remove tumor tissue to prevent its spread and metastasis, and is currently used more. However, the limitation of surgical treatment is that it is only useful for early-stage tumors. For advanced or metastatic tumors, the operation is difficult and the curative effect is poor. 2. Radiotherapy and chemotherapy, radiotherapy and chemotherapy is the use of...
