How radiotherapy and immunotherapy work together to achieve a 1+1＞2 effect in cancer treatment

Synergistic effects of radiotherapy and immunotherapy are important in cancer treatment

The synergistic effect of radiotherapy and immunotherapy is of great significance in cancer treatment. Reasonable control of the range and dose of radiotherapy can effectively improve the treatment effect and prolong the patient's survival. However, the coordination of radiotherapy and immunotherapy is not a simple 1+1, but requires precise control of every link to achieve the effect of 1+1>2. In actual operation, we need to act cautiously to ensure that each treatment measure can play the greatest role.

The scope and dose control of radiotherapy are key. Radiotherapy over a large range, such as the primary lesion, mediastinal lymph nodes, etc. are all within the treatment range, combined with immunotherapy, may lead to death, which is a situation we need to be highly vigilant about. On the contrary, if the metastatic lesion or primary lesion is small, local peripheral radiotherapy is not a big deal. Because the range of radiotherapy is limited, the impact on patients is relatively small. However, the synergy of radiotherapy and immunotherapy is not a simple matter, and theoretical effectiveness does not guarantee good results in practice. Therefore, in actual operations, we need to act with caution and reasonably adjust the range and dose of radiotherapy according to the specific circumstances of the patient.

Radiotherapy has various effects, such as increasing local inflammatory responses, and its range and dose are crucial. The higher the single dose, the stronger the immunity. However, if the equipment is not accurate enough, the dose in the low-dose area is high, and combined with immunotherapy, it may cause a larger reaction. Therefore, when formulating a treatment plan, we need to fully consider the various effects of radiotherapy and the synergistic effects with other treatment methods.

In other areas, such as the femur, pelvis, vertebral body, cervical lymph nodes, or brain metastases, adding immunotherapy to radiotherapy may lead to adverse reactions such as interstitial pneumonia, especially mediastinal radiotherapy. Radiotherapy to the mediastinal lymph node area plus radiotherapy to the primary lesion, and radiotherapy combined with immunotherapy over a larger range, have a higher probability of adverse reactions. Therefore, within one month before and after immunotherapy, we need to carefully consider the synergistic effect of radiotherapy and immunotherapy to avoid unnecessary side effects.

In short, the synergy of radiotherapy and immunotherapy is a complex and critical process. In actual treatment, we need to reasonably adjust the treatment plan according to the specific situation of the patient to achieve the best treatment effect. At the same time, we also need to continuously explore and improve treatment methods in order to achieve better results in future cancer treatment. In this process, caution and meticulousness are crucial. Only in this way can we truly achieve a treatment effect of 1+1>2.
