Based on years of clinical observation, the effect of cancer treatment has the following main factors:
Factors affecting tumor treatment (1) the pathological type and degree of differentiation. The biological characteristics of the tumor cells themselves on the efficacy and prognosis of the most important. From the tumor's growth pattern for exogenous tumor sensitivity to radiotherapy and chemotherapy, the prognosis is good; ulcerative and endogenous tumor infiltrating poor sensitivity to radiotherapy and chemotherapy, the prognosis is poor. From the degree of differentiation, the higher the degree of tumor cell differentiation, the lower the grade, the better the prognosis; otherwise the worse the prognosis. Source of tumor tissue from the view, derived from epithelial tissue and glands of the cancer, chemotherapy, radiation sensitive, relatively good prognosis; and from fiber, fat, bone tissue sarcoma of radiotherapy and chemotherapy is not sensitive to a poor prognosis .
Factors affecting tumor treatment (2) the growth of tumor location, size and growth rate. Tumor grew in some parts of the treatment is not easy to achieve, the more treatment is not ideal. If the length of some important organs in or around the tumor is larger and faster growth, the prognosis may be poor.
Factors that affect the therapeutic effects (3) the case of tumor metastasis. Whether the tumor metastasis has occurred and to what extent the transfer, directly affect the efficacy of the tumor and prognosis. If the first visit to have lymph node metastasis, it will reduce the 5-year survival rate; if distant metastasis has occurred, especially in the transfer to the brain, lung, liver and other vital organs, the prognosis is even worse.
(4) found sooner or later and the diagnosis. Early detection and diagnosis of cancer can receive timely treatment is a prerequisite for correct diagnosis is to develop reasonable and effective basis for treatment. This curative effect and prognosis of cancer has great impact. Correct pathological diagnosis should include cancer diagnosis, staging, and the general condition of the patient assessment.
(5) treatment is reasonable, initial treatment is complete. The modern concept of cancer treatment is a comprehensive treatment, no matter what treatment, if the initial treatment to achieve cure, the likelihood of recurrence after a small, prognosis of course, like; the contrary, if initial treatment is not complete, there is residual tumor cells or tissues , then the more chance of recurrence, poor prognosis.
(6) health and mental state. If the patient normally healthy body, strong resistance, no other disease, the prognosis is good; if combined heart, liver, lung, kidney disease, the prognosis is poor. This is the elderly poor prognosis, one important reason for high mortality. In addition, to maintain a good psychological quality, morale, and establish the firm belief to overcome the disease, treatment and prognosis of the tumor will play a good role.
Factors that affect the therapeutic effects (7) sex and age. Generally speaking, women's 5-year survival rate and cure rate than men; and age on the prognosis, is still not general conclusions. Some people think that to occur in young sarcoma, malignant high, rapid development and poor prognosis. In fact, not all, may also occur before puberty slow tumor growth, such as melanoma, thyroid cancer, etc.; the contrary have developed rapidly in the elderly malignancies, such as lymphosarcoma and breast cancer and so on.
Factors affecting tumor treatment (8) pregnancy. Most of the growth of tumors in early pregnancy soon, and in pregnancy, 3 – 9 months of slow growth, production and post-weaning growth and rapidly, is still in the growth of cancer patients must be strictly female contraception.
