Postoperative biological therapy for esophageal cancer

Postoperative adjuvant biological therapy for esophageal cancer can help improve the patient's prognosis. Basic and clinical studies have shown that tumors can severely suppress the body's immune function. Surgery is both a sudden blow to the immune function and an effective means to relieve the tumor's suppression of the immune function. However, a long recovery period is required after surgery. This period is the stage when the body's immune function is the lowest, the tumor cell growth index is the highest, and the growth rate is the fastest. It is also the best time for tumor cells to be suppressed and phagocytosed by the body's cellular immune function, and it is also the best time for the body's immune function to recover.

In this situation where chemotherapy and radiotherapy are not allowed right after surgery, how can we not miss this rare opportunity and use biological response modifiers for biological treatment in a timely and effective manner to help and promote the body's immune function to recover and improve as soon as possible, and inhibit and kill tumor cells before they grow and proliferate in large quantities? This will effectively accelerate the patient's postoperative recovery and prevent tumor recurrence and metastasis, and will play an unexpected, effective and multiplier effect and survival benefit. However, this treatment plan and treatment timing are often ignored by doctors, especially surgeons. After the operation, they just passively wait for the patient to recover naturally, and rarely or basically do not give the patient biological treatment as soon as possible after the surgical response period, so most patients lose the favorable immunotherapy period.
