I wonder what the author's purpose is in asking such a question?

There is no first for disease in this world.

Any disease he has degrees, just like you ask who is more powerful, a dog or a tiger? What if it's a big ferocious dog compared to a newborn tiger cub?

A malignant cancer is malignant because it has distant metastases, which is why there is a high chance of cancer recurrence. The wildfire will not be eliminated, and it will grow again in the spring. Because he has metastasized to distant areas, you can't control the distant metastasized areas by removing the lesion in one area.

For example, if osteosarcoma, which is a highly malignant tumor in orthopedics, has its primary lesion in the lower leg, it will metastasize to the lungs and other places at a very early stage. At this time, even if you do amputation of the thigh, but can not treat the metastatic foci in the lungs, the patient will soon develop lung and systemic lesions, and thus die.

The pathogenicity and mortality rate of medicine refers to how many people in a thousand develop and die, and when it falls on one enough person, it is 100 percent if they develop and 0 percent if they do not develop. There is no reference for patients.

If you ask the cancer with the highest recurrence after surgery, then I think it is liver cancer. This is because surgical resection of liver cancer is the preferred method. The 5-year postoperative recurrence rate is as high as 80% for large hepatocellular carcinoma and 40%-60% for small hepatocellular carcinoma. The high postoperative recurrence rate is one of the difficulties in liver cancer treatment. Primary liver cancer is the second leading cause of tumor death in China, and its high recurrence rate after radical resection seriously affects the overall surgical efficacy of cancer. A large series of clinical data at home and abroad show that the recurrence rate of liver cancer after surgery is about 40%-50% at 3 years, and 60%-70% or even higher at 5 years.

Patients with postoperative recurrence of hepatocellular carcinoma have serious abdominal adhesions, and the anatomical structure of intrahepatic blood vessels and bile ducts is changed, which also requires higher reoperation resection techniques. Patients with postoperative recurrence of hepatocellular carcinoma after 1 or more times of surgical treatment, or multiple times of TACE and other local treatments, the liver morphology is abnormal, the degree of cirrhosis is obviously aggravated, the liver function is seriously impaired, and they cannot even tolerate further surgery and chemotherapy.

The high recurrence rate of non-surgical and other cancers is glioblastoma, which is the most common intracranial primary malignant tumor, and glioblastoma accounted for about 45.2% of newly diagnosed intracranial organisms in the United States from 2006 to 2010. Glioblastoma is characterized by high recurrence rate and high mortality rate, with a median survival of only 14-16 months, a median time to recurrence of 6.2 months, and a median survival of only 25-30 weeks after recurrence. There is still no optimal treatment plan for recurrent glioblastoma.

I hope the above answer can help you
