Is it possible to cure cancer of the 4th degree?
To evaluate the life expectancy for cancer, the term "five-year survival" is used. It includes the number of patients who survive 5 years after establishing an accurate diagnosis. Based on this characteristic, you can determine the effectiveness of treatment, the aggressiveness of the tumor, and most importantly answer the question: "Is it possible to curecancer of the 4th degree? ».
Prognosis and whether it is possible to cure cancer of the 4th degree?
The prognosis depends on the cellular composition, the severity of the pleural damage, the pericardium and the presence of metastasis in other organs (adrenal glands, mammary glands, bones). With non-small cell composition, the survival rate ranges from 2% to 13%, with small-cell form - no more than 1%.
In the fourth stage, in most cases, the neoplasm can not be surgically intervened. In connection with this, irradiation and chemotherapy are used for therapeutic purposes.
In addition, complications develop, for example, pleurisy with accumulation of exudate in the pleural cavity, which requires the implementation of thoracoenesis, or pericarditis, when the fluid is localized in the pericardial bag (pericardium).
Given the location of the cancer process, the presence of metastases, survival is in the range of 13% to 17%. Improve this indicator is possible with intra-arterial chemotherapy and radiation.
Surgery for a stomach tumor is carried out only for life indications (with bleeding, violation of food through the digestive tract). Resection (partial removal) of the stomach or gastrectomy (complete excision of the organ) is performed, anastomoses between the stomach and intestine are formed. If there is stenosis of the esophagus, the stand may be staged. The most favorable localization is in the cardiac part of the stomach.
At a cancer of a liver of 4 stages the survival rate makes no more than 6%. This is due to the intensive growth of the tumor with involvement in the oncological process not only shares liver, blood vessels, but also surrounding fiber, spleen with distant metastasis to the lungs, intestines.
Neoplasm is so aggressive that in the course of 3-4 months the process can reach the fourth stage. Operation (resection of the liver) is a rather difficult surgical intervention, which requires high qualification of doctors and a correctly conducted postoperative period.
As for chemotherapy, they do not have a positive therapeutic effect. Currently, chemoembolization and radiofrequency embolization are most often used.
If it is impossible to perform the above surgical treatment, laparocentesis is performed to aspirate ascites from the abdominal cavity. In addition, with the growth of clinical symptoms, pronounced changes in laboratory tests, drainage of intrahepatic bile ducts or choledocha (common bile duct) is used.
At 4 stages, gliocarcinoma, astrocytoma, glioblastoma multiforme are most often diagnosed, in which the prognosis is unfavorable, and the percentage of surviving patients is extremely low.
The diagnosis is often carried out at a late stage after additional instrumental examinations, such as CT and MRI. Not always patients turn to the doctor in a timely manner, because at the beginning of tumor development only cephalgia (headache) and dizziness may be disturbing.
In the future, focal symptomatology is added depending on the localization of education. So, there may be motor disorders (paresis, paralysis), coordination disorders, visual, sensitive, speech dysfunctions.
With an increase in cerebral edema, due to the growth of the tumor, convulsive seizures appear, the intellectual sphere suffers, which ultimately leads to a lesion of the brainstem with a violation of breathing and abrupt changes in the arterial pressures.
Radiation, chemotherapy is used to prolong life, but this is not always possible. Surgical tactics are chosen only with a certain localization of the neoplasm. Without any medical intervention, life expectancy does not exceed six months.
The five-year survival rate is 15-22%. It should be noted that in addition to the radical surgical method (mastectomy, removal of lymph nodes, pectoral muscles) chemotherapy is required.
However, it is worth noting that after their introduction, it is also possible to deteriorate health (there is a depression of the immune system, exacerbation of chronic foci of inflammation, depression of the hematopoietic sprouts).
The courses are necessary to prevent further metastasis and inhibition of malignant growth.
With a lesion of the uterus of the 4th degree, the chances do not exceed 3-9%, as there is a spread to the pelvic organs with the formation of a conglomerate. In this case, often the conglomerate is considered inoperable, therefore, chemotherapy is performed.
The operation is performed only when involved in the intestinal process with the development of intestinal obstruction or urinary tracts - to restore the outflow of urine. The decision to conduct radiation exposure to uterine cancer is taken in each case individually.
With regard to a similar cervical disease, the survival rate is about 9%. Aggressiveness of the malignant process leads to rapid transformation of the preinvasive type into an invasive one, provoking intensive growth and spreading.
With the involvement of surrounding organs (intestines, bladder), fistula formation is possible. The tactics of treatment include "chemistry surgical care is provided in urgent situations.
Cancer of the ovary
With 4 degrees of damage to the ovaries, the malignant conglomerate goes far beyond the small pelvis with metastasis in distant structures, organs, for example, mammary glands, lungs, liver, brain, bones.
Survival does not exceed 18%, depending on aggressiveness, cellular composition of education, the presence of concomitant pathology and the general state of human health.
In general, the ailment has a high survival rate. In some sources it is possible to find figures up to 30%. However, it is necessary to understand that the indicator directly depends on the age, the level of immunity, the rate of spread of the tumor and the treatment used.
The operability of the tumor is determined individually. "Chemistry" can be performed before or after surgery. It is necessary to slow the spread of metastases, inhibit their growth. Radiotherapy is also prescribed.
Having examined the cancer of 4th degree of different localization, we now answer the question: "Is it possible to cure grade 4 cancer? ». Completely get rid of cancer is impossible in view of the presence of metastases and large spread of the tumor. However, due to medical methods, it is possible to significantly improve the quality of life and increase its duration..
