大腸癌之治療

Treatment of Colorectal Cancer

惡性腫瘤長年來高居國人十大死因的第一位，在台灣地區因大腸直腸癌致死的案例，也在逐年增加中。大腸直腸癌位居癌症死因的第三位。在台灣地區因大腸直腸癌致死的案例，根據行政院衛生署的統計報告顯示：目前台灣每年大腸直腸癌新病例的產生逐漸增加。癌症的產生不外是遺傳和環境所造成。然而大腸直腸癌據家族遺傳傾向者約佔15～20%，大部分的大腸直腸癌是不具遺傳傾向而偶然發生的，此即所謂的偶發性（sporadic）大腸直腸癌。偶發性大腸直腸癌一般的想法是大腸黏膜細胞因長期處在不正常內在環境或外在環境的刺激下導致基因多重突變造成。末期大腸直腸癌手術後的預後不盡理想，所以早期的診斷就顯得相當重要。大腸直腸癌的進展較緩慢，不過卻有很大的癌症轉移率。因此，如果能夠早期篩檢出大腸直腸癌或其高危險群，適當使用中醫藥治療，對於此病症的控制、治療以及降低死亡率，會有很大的幫助。

Cancer (malignant tumor) has ranked the number-one cause of death in Taiwan for many years. According to the statistics report from the Department of Health, the number-three cause of death due to cancer is the colorectal cancer since the case fatality rate of colorectal cancer in Taiwan is increasing year by year. The occurrence of cancers is caused by inheritance or/and environment. Although colon cancer sometimes has a familial or hereditary component, it usually doesn't. Around 15-20% of colorectal cancer cases are due to familial predisposition. The vast majority of colorectal cancers are sporadic colon cancer. They are likely to occur by chance, being not related to genetics or family history. It's thought that colorectal cancer appears to be multifactorial in origin and includes environmental factors and a genetic component. The early diagnosis becomes very important since the prognosis after surgery for final-staged colon cancer is not good. Colon cancer is a kind of indolent tumors, but it has a higher incidence rate of metastases. Therefore, early cancer screening along with TCM treatment is helpful for the treatment, control and decrease in death rate of colon cancer.
