Cancer, such as lung cancer and liver cancer, is a major disease that threatens human health. Once cancer is detected, it should not be delayed and should be actively diagnosed and treated immediately. Then, what is the key to diagnose and treat malignant tumors? The latest concept of modern cancer treatment is precision and green.
1. Precise diagnosis and clinical staging are the prerequisites for the treatment of various cancers.
Before cancer treatment is started, it must be diagnosed clearly, and experimental treatment and exploratory treatment are not allowed.
The onset of cancer is insidious and there are usually no obvious symptoms. If patients can be investigated and treated early, early lung cancer and liver cancer can be cured and the 5-year survival rate can be over 90%. Therefore, early detection is the only hope for cancer patients to be cured.
(1) Firstly, we can detect the signs of cancer through medical screening such as various tumor marker tests, ultrasound examination and CT scan.
(2) Further, it is necessary to “triangulate” the lesion, i.e. qualitative, quantitative and localization. At present, the most advanced imaging instruments in the world can detect the active molecules of cancer and accurately determine the anatomical location, i.e. qualitative, quantitative, localization and clear staging, and the most effective and reliable method for early detection of cancer is PET-CT.
(3) Finally, using image-guided methods, percutaneous puncture of the tumor site is performed to obtain a small amount of cancer tissue cells for pathological examination, and eventually cancer cells are found and the cell type is determined.
Hint: Nowadays, technical means are able to put special markers on cancer cell molecules and display them precisely on CT, so as to find traces of cancer and determine the benign and malignant nature, size, scope and number of tumors, which is PET-CT (called in Chinese: Positron Emission Tomography). Nowadays, the technical means are also capable of minimally invasive puncture to tumors the size of peanut rice under the guidance of CT and ultrasound, basically without complications such as bleeding, pneumothorax and metastasis, to safely determine the diagnosis and decide the treatment plan and method according to the stage of the lesion. It has done the precision and green of cancer diagnosis.
Experts recommend cancer diagnosis methods in order: ultrasound or chest X-ray → tumor markers → CT or MRI → PET-CT → puncture biopsy → surgical exploration.
Typical case: Patient Cui Moumou, male, 81 years old, 50 years smoking history, in November 2005, because of cough with blood in sputum, chest X-ray found shadow in the lower lobe of right lung, according to pneumonia after 2 weeks of anti-inflammatory treatment did not improve, CT examination suspected malignant tumor with mediastinal lymph node metastasis, tumor marker CEA elevated, immediately PET-CT examination diagnosed as limited malignant tumor in the lower lobe of right lung, so in CT He was then diagnosed as lung adenocarcinoma by CT-guided percutaneous puncture biopsy and underwent CT-guided radiofrequency ablation of lung tumor, and after the operation, he took oral chemotherapy drugs for 4 cycles.
2. Precise treatment and green methods are the key to cancer recovery.
Cancer treatment, just like fighting the enemy, should be: “stable, accurate and hard”. (1) Stable: It is safe and green, using the least invasive, minimally invasive and even puncture methods to treat tumors, and using non-polluting, non-residual and non-toxic “green” energy, such as heat, electricity, or natural drugs or even human body’s own components such as lymphocytes, antibodies and even human digestive juices to kill cancer cells. At the same time, it can also enhance or at least not damage the immune function of the patients, so that the treatment can maximize the patients’ recovery from the treatment and ensure a good quality of life before and after the treatment, so that the patients can return to society, work and life as soon as possible. (2) Accurate: Under the guidance and monitoring of CT, ultrasound and other imaging means, the lesion is treated accurately, while the surrounding normal tissues are protected to reduce damage. (3) Ruthless: It means effective treatment means, for example, besides surgical resection of tumor, in recent years, tumor ablation technology, especially radiofrequency ablation for isolated early liver cancer, is greatly respected.
Hint: Nowadays, high-tech technical means have been able to convert radio energy into heat energy through very fine electrodes in tumor tissues to scald cancer cells, or lower the temperature of cancer tissues until freezing cancer cells, or inject chemical drugs directly into the lesion to kill cancer cells, and the dead cancer cells are engulfed by immune cells of the body, and the tumor gradually “disappears or melts”. The tumor will gradually “disappear or melt away” and the body’s ability to actively identify and attack cancer cells will be strengthened, which are radiofrequency ablation, argon helium knife cryoablation and chemical knife chemical ablation technologies.
Experts recommend: to select cancer treatment methods sequentially according to the treatment norms set by the Ministry of Health.
(1) Early isolated tumor without surrounding metastasis should be removed by surgery. For those who cannot be operated or refuse surgery, ablation treatment can be chosen as the main treatment.
(2) For mid-stage large tumors with nearby metastases, ablation or precision radiotherapy such as 3D conformal radiotherapy or Gamma Knife focused radiotherapy with chemotherapy.
(3) Patients with advanced systemic metastases should be treated mainly with chemotherapy, together with ablation or radiotherapy to reduce the tumor load, and with traditional Chinese medicine to regulate the body function and improve the quality of life.
(4) Immunotherapy can be used throughout the cancer treatment.
(5) Targeted drug therapy can be considered if molecular mapping is possible.
In conclusion, the current cancer treatment emphasizes individualized and comprehensive treatment, and the first treatment is very crucial.
Typical case: Patient Feng Moumou, male, 61 years old, 20 years history of hepatitis B. In January 2010, because of wasting, ultrasound found nodular occupancy in the right lobe of liver 3cm in size, methemoglobin 100ug/L, CT examination suspected primary hepatocellular carcinoma, so CT-guided percutaneous puncture biopsy, diagnosed as primary hepatocellular hepatocellular carcinoma, and CT-guided liver tumor chemical knife chemical ablation, 3 cycles of The patient was then diagnosed with primary hepatocellular carcinoma and underwent CT-guided liver tumor chemical knife chemical ablation.
Research data: According to the latest domestic and foreign reports, the 5-year survival rate of radiofrequency ablation treatment for early liver cancer is nearly 50%, which even exceeds the effect of surgical resection. In the United States, the tumor ablation technology represented by radiofrequency ablation and surgery were identified as the preferred curative methods for early stage liver cancer in 2009. Tumor ablation technology is to kill liver cancer cells directly by physical means such as radiofrequency heating (radiofrequency ablation), freezing (argon-helium ablation), or chemical ablation such as anhydrous ethanol and dilute hydrochloric acid, which is minimally invasive, safe and efficient. Precise and green treatment can obtain the best therapeutic effect, which brings new hope to the treatment of early stage tumors.
3. Patients are cautioned that the treatment of cancer requires getting out of the following misunderstandings.
(1) Cancer is an incurable disease. Since there is a great progress in the diagnosis and treatment of cancer and many new methods have emerged, we hope that patients will actively collect useful information and strive to overcome cancer with a sunny mood and the latest treatment methods.
(2) Blind treatment without clear diagnosis. Correct diagnosis and staging are the prerequisite for accurate treatment. Blind treatment may miss the best time for treatment.
(3) Cancer cannot be told to the patient. The request of family members for medical staff to hide the true condition from the patient is considered as a protective measure for cancer patients. In fact, we should adopt the attitude that we do not conceal the truth, but we should not scare the patient. Because patients themselves have the right to know about their condition, and cancer is an objective fact, patients need to understand their condition and actively cooperate with the treatment, while building up their confidence and perseverance to overcome the disease. Concealment will cause patients’ suspicion and non-cooperation with treatment, but delay the condition and the best time for treatment.
(4) Secret prescriptions and biased health care products can cure cancer. There is no direct evidence of curing cancer in the folk remedies for cancer, and some of them may not cure cancer. Patients tend to be overwhelmed and inevitably fall for them, wasting money, not getting proper treatment and losing the best time for real treatment. Various “anti-cancer supplements and nutritional products” have no therapeutic effect at all; the so-called “experimental results” are all the results of animal experiments and cell culture, and there is no real data on clinical application for patients. They can only be used as adjuvant treatment with surgery and radiotherapy as nutritional support.
(5) Increasing nutrition will make cancer cells grow faster. Some patients think that if they eat nutritious things, cancer cells will grow faster and try to reduce nutrition to “starve” cancer cells. In fact, tumor treatment needs good body assurance, so it is necessary to enhance nutrition properly in cancer treatment.
(6) No need to review after treatment. Some patients think that the symptoms are relieved or the lump disappears after treatment and stop further examination and treatment, which results in recurrence and metastasis soon and deterioration of the disease, so that all the treatment is abandoned. Cancer is cured by 5-year survival period, so it is very necessary to continue treatment with regular check-ups.
