Global cancer treatment ｜ Tokyo, Japan is the best, with the highest score.
On November 10th, China Fudan Hospital Ranking was just released, which was released by Hospital Management Institute of Fudan University. Drawing lessons from the evaluation method of "Best Hospital Ranking" in the United States, it adhered to the core of clinical discipline level and specialty reputation, taking into account the scientific research output of that year, which attracted great attention.
However, on a global scale, which city has the strongest comprehensive strength in cancer treatment, do you know? A few days ago, Britain also published a "list of the best hospital cities in 2019", which evaluated the overall level of cancer treatment in 100 cities around the world from three aspects: infrastructure, nursing quality and access rights.
The survey found that Tokyo, Japan is one of the best cities for cancer treatment in the world. Japan’s capital ranks first in the efficiency of cancer treatment, with the highest score in the overall quality of diagnosis and treatment, the largest number of first-class hospitals, and a high score in accessibility.
The second best hospital for cancer treatment in the world is located in Boston, Massachusetts, USA. Its infrastructure score is the highest, including the number of first-class medical universities, first-class hospitals and sufficient mental health counseling experts for patients.
The third place is London, England, followed by Paris, France, and Seoul, South Korea ranks fifth. It should be emphasized that this survey only examines the overall situation of hospitals in specific locations, not individual institutions.
Beijing is the only city in China, ranking 83rd. It performed well in the management of adverse events, drug prices and disposable medical expenses. In contrast, Beijing, Dubai, United Arab Emirates and Krakow, Poland were rated as the three cities with the worst cancer treatment efficiency, indicating that we still have a lot of room for improvement.
01
Japan, the leading cancer treatment technology in the world.
As early as 30 years ago, Japan began to study cancer cure methods and constantly broke through innovation. Among them, the professional anti-cancer physical examination institution, the specialized cancer treatment hospital, has long been famous all over the world.
Nowadays, Japan has gradually formed a mature cancer screening, cancer treatment and cancer recurrence prevention as three steps to prevent and treat cancer. No matter TV, magazines and new media, they will try their best to popularize the significance of early onset and active treatment of cancer, which has been endorsed by many medical schools and research institutions at home and abroad.
Japan’s 30 years of painstaking research on cancer has created a world-leading cancer prevention and control system, making Japan second to none in the field of cancer treatment in the world, thus attracting a large number of foreign patients to receive treatment and examination.
Japanese cancer treatment has three characteristics: high cure rate, small side effects and low recurrence rate. Before receiving Japanese cancer treatment, the patient underwent a Japanese cancer physical examination, and the smallest cancer below 5 mm can be found, which is in stage I, and the cancer cells have not infiltrated (on the epidermis and mucosa, and have not penetrated into the muscles), spread (spread to all organs), metastasized (transferred to other organs), or even stage 0 (primary cancer). It is fortunate to find such a cancer, which can be cured by resection. If you pay attention to lifestyle changes, it will generally not recur.
Known as the king of cancer, the early detection rate of pancreatic cancer is very low, only 5% ~ 7%. If doctors are inexperienced, pancreatic cancer is often misdiagnosed as gastrointestinal or hepatobiliary diseases, and the misdiagnosis time is generally as long as 3 ~6 months. Most patients can’t be surgically removed when they are diagnosed, and they will die in about half a year, and the survival rate after 5 years of operation is less than 5%.
In Japan, the 5-year survival rate of pancreatic cancer can be kept at a high level of about 42% through early cancer prevention and early treatment.
Good treatment, we must protect the normal tissue.
Japan’s leading cancer treatment technologies mainly include heavy ion therapy and proton therapy. Among them, heavy ion radiotherapy and proton radiotherapy are the most advanced radiotherapy methods to treat tumors, and their clinical effects are comparable to those of scalpels.
Doctors only need to aim the particle beam of heavy ions and protons at the tumor to take a photo, and the tumor tissue will die quickly. It has almost no harm to the healthy tissue around the tumor, and it sweeps away the skin damage, visceral damage such as radiation-induced pneumonia, bone marrow suppression, hair loss, low immunity, etc. brought by all the common radiotherapy methods at present, and it has no bleeding, infection, accidental injury, etc. caused by the scalpel, so it is called the magical invisible scalpel.
02
Heavy ion therapy
Heavy ion therapy is mainly used to treat local malignant tumors, especially diseases that are difficult to cure by traditional methods. Compared with other common radiotherapy, it can accurately locate tumor tissue and reduce the damage to surrounding normal tissue.
Because the types and spread of cancer cells are different, the treatment methods are also different. Whether heavy ion therapy can be carried out needs to be judged in advance. According to the comprehensive research institute of radiation medicine, the statistical results of patients who have received heavy ion therapy so far clearly show that:
(1) It has a good effect on treating the following malignant tumors, namely, cervical cancer (including eye cancer), intracranial and skull base cancer, lung cancer, liver cancer, prostate cancer, bone cancer, soft tissue cancer, uterine cancer and local recurrence in pelvis after rectal cancer operation.
(2) A series of cancers that are resistant to ordinary radiation (such as X-rays) have a good effect, such as well-differentiated adenocarcinoma, adenoid cystic carcinoma, hepatocellular carcinoma, bone cancer, cartilaginous carcinoma and malignant melanoma.
However, large-area metastatic cancer is not suitable for heavy ion beam therapy. There are patients such as hematologic cancer, gastric cancer, colorectal cancer (primary site), and patients who have received radiotherapy in the same place before. Please consult a doctor for details.
03
Proton therapy
Proton particles are extremely tiny, and one trillion protons are only one millimeter long in a straight line. Protons are positively charged, which can be made to move at high speed by electric field, reaching extremely high energy. Using proton accelerator to generate high-energy proton beam, which is injected into human body under precise control, can accurately release energy to the lesion to achieve therapeutic effect, which is the technical superiority of proton therapy.
Because proton therapy has the characteristics of strong penetration, good dose distribution, high local dose, less side scattering and small penumbra, it is especially suitable for treating tumors surrounded by important tissues and organs.
The cancers suitable for proton radiation therapy mainly include head and neck cancer (nasal cavity and paranasal sinuses, throat, salivary glands, skull base, etc.), lung cancer, liver cancer, prostate cancer, bladder cancer and other primary tumors. In addition, it can also treat pelvic recurrence and single metastatic tumors (liver metastasis and lung metastasis) after rectal cancer surgery.
We live in an era when we talk about the discoloration of cancer. Cancer is not an incurable disease, but a chronic disease that can be prevented in advance, that is to say, cancer is not a terminal disease.
For patients, if cancer is unfortunately detected, we must pay attention to the opportunity of "first treatment". Because the medical results are often irreversible, the chances of cure for almost all cancers may mainly depend on the first treatment. Japan is a country that attaches great importance to surgery, and the top hospitals for cancer treatment are all famous for surgery. For patients who have surgery opportunities, they can make rational choices according to their own conditions.
According to the Nihon Keizai Shimbun, 75% of cancer patients in Japan did not leave their jobs due to illness, and 80% of them said that their treatment would not affect their work. The reason is that most cancer patients in Japan are found early and treated early, and early cancer can be basically cured without affecting their normal work and life.

Cancer screening
Toshiba Corporation of Japan issued a statement on November 25th, saying that it has developed a method to diagnose cancer through blood test with an accuracy rate of 99%.
The basis of diagnosis is to determine the type and concentration of small noncoding RNA molecules secreted by cancer cells into the blood. The whole analysis process only needs one drop of blood and lasts about two hours. Therefore, the company has specially developed a portable device with a built-in diagnostic chip.
This method can diagnose 13 kinds of cancers, including gastric cancer, breast cancer, liver cancer, esophageal cancer, pancreatic cancer, intestinal cancer and bladder cancer. Toshiba said that even in the earliest stage of cancer, this method is still effective.
In recent years, the number of cancer patients has been increasing, and Japan has been actively developing new anti-cancer methods. Moreover, in this respect, artificial intelligence has begun to be more and more widely used.
In addition, according to statistical reports at home and abroad, the comprehensive cure rate of gastric cancer in Japan is as high as 80%, and the first-stage gastric cancer even reaches 98.1%! Far more than 30%~40% in China and the United States, it can be said that it stands out from the crowd and dumped us several blocks. Rich people can go to Japan for physical examination and surgery. What should ordinary people do?
We might as well learn from Japan’s anti-cancer experience, and truly achieve early prevention, early detection, early diagnosis and early treatment, and reject gastric cancer thousands of miles away!
The 5-year survival rate of gastric cancer in Japan is high, because most of the patients detected are early patients, the disease develops slowly, and the probability of recurrence and metastasis is low. At the same time, because of their young age and good physical condition, they are more tolerant to surgery, radiotherapy and chemotherapy, and the treatment effect is of course good. Japan’s secret to deal with gastric cancer is early screening, early detection and early treatment.
In 1964, 400,000 people were screened, by 1970, 4 million people were screened, and after 1990, about 6 million people were screened for gastric cancer every year. The early diagnosis rate of gastric cancer in Japan is as high as 50% to 70%, while the cure rate of early gastric cancer is more than 90%, even close to 100%.
In the United States, the incidence of gastric cancer is very low, which is a rare disease. Compared with breast cancer, colorectal cancer and prostate cancer, Americans pay relatively little attention to the prevention and treatment of gastric cancer, and the early detection rate is low. China is a country with high incidence of gastric cancer, but people’s awareness of prevention and treatment is not high. Only 10% to 15% of early gastric cancer is found, and many people are diagnosed with advanced gastric cancer. More than 70-80% people will not live for five years. Many people died within a few months after being diagnosed.
Since the cure rate of gastric cancer in Japan is so high, it is attributed to the early detection and treatment of gastric cancer in Japan, so how do they do it? Very simple, mainly relying on endoscopic screening. In the eyes of many people in our country, gastroscopy is a color-changing examination. Many people delay their illness because they refuse gastroscopy, and few people take the initiative to ask for gastroscopy unless they have to.
According to reports, Japan has a population of about 127 million, and about 15 million cases of gastroscopy are completed every year. It is equivalent to 12.5% of people having a gastroscope every year. Converted, it is equivalent to that 62.5% people have had a gastroscope at least once in five years. Convert it into high-risk groups, and almost all of them have been screened.
On the other hand, in China, many people are afraid of gastroscopy. The detection rate of gastroscopy is very low, the detection rate of early cancer is less than 20%, and the survival rate in five years is less than 30%. That is to say, most people who are diagnosed may not survive for five years. 80% of patients with early gastric cancer have no obvious symptoms, and even if there are symptoms, they are atypical symptoms, such as loss of appetite and abdominal discomfort, which are difficult for patients to pay attention to. Only regular gastroscopy can find its clues.
According to the latest 5-year survival rate data of gastric cancer released by National Cancer Research Center of Japan:
The 5-year survival rate of primary gastric cancer is as high as 98.1%.
Secondary gastric cancer: 66.4%,
Stage III gastric cancer: 47.3%,
The 5-year survival rate of stage IV gastric cancer is only 7.3%.
Because the proportion of advanced gastric cancer in Japan is very small, the overall 5-year survival rate is higher than 80%, which is unique in the world! It can be seen how important it is to find and treat early! Compare the figures in China: the overall 5-year survival rate is less than 40%; Stage 3 or 4 gastric cancer accounts for 80% of the total cases, and the 5-year survival rate is less than 30%. Only 15-20% of patients have early cancer. In other words, most patients will not live for five years.
Because of its large population base and high incidence of gastric cancer, China has contributed more than half of the cases in the world. Under the background that there is no revolutionary progress in the treatment of gastric cancer at present, it is particularly important to do a good job in the prevention and early screening of gastric cancer.
