The essence of "slow-release reservoir therapy" is to change the traditional administration mode of chemotherapy, which is mainly suitable for solid tumors. To put it simply, under the guidance of B-ultrasound, CT and other images, anticancer drugs combine with a special reagent, penetrate into tumor tissue, form a huge "drug warehouse", and then slowly release anticancer drugs, so that the time for drugs to stay in the tumor can be extended by more than dozens of times, and drugs can be released continuously. In this way, the local drug concentration of the tumor has increased from 5% to 95%. If cancer cells want to survive, they have to take medicine and die as soon as they take medicine. 95% of anticancer drugs are stored in tumors, and only a few drugs flow to normal tissues of the whole body, so the side effects are small and the anticancer effect is very obvious. It usually kills cancer cells within half a month. After death, the original part of cancer cells only leaves a scab, and then the tumor after death is removed by surgery. This therapy shortens the course of treatment, reduces the dosage and has no side effects, so compared with traditional treatment methods, the treatment cost of patients is greatly reduced.
"Slow-release bank therapy" is suitable for cancer with solid tumor. At present, except brain tumor, the tumor size is above 1 cm, which can be seen by imaging instrument, so this therapy can be used. At present, it has treated liver cancer, liver metastasis cancer, esophageal cancer, cardiac cancer, lung cancer, rectal cancer, gastric cancer, bladder cancer, testicular cancer, prostate cancer, thyroid cancer, renal cancer and retroperitoneal tumor except leukemia, brain tumor and bone metastasis (all drugs are approved by the local national health department and designated by medical insurance institutions). Even patients with weak constitution can apply "slow-release and long-term therapy".

Theoretically, tumors in all parts of the body can be treated with sustained-release banks as long as they can be detected by instruments. At present, the clinical indications in our hospital are: A patients with advanced solid tumor; Patient B is in the early stage, but cannot be treated surgically due to other diseases; Although patient C was suitable for surgery, he refused surgery because of too much trauma. Patients with postoperative recurrence. In particular, the effect of slow-release bank therapy plus activated radiotherapy and chemotherapy on early tumors is very ideal. We treated 2 patients with early breast cancer with slow-release bank therapy and active radiotherapy. After treatment, the local tumor disappeared and no cancer cells were found by pathological examination. After follow-up, the patient did not have local recurrence. Sustained-release chemotherapy in tumor-sustained-release reservoir therapy, once put forward, caused a sensation in the American tumor community and was evaluated as the last revolution in tumor treatment. In 2004, the slow-release reservoir therapy was patented in the United States; In 2006, he obtained a patent for invention in China, and in 2007, he obtained an Australian patent for invention.
