ABSTRACT
Objective For better recognition of the hereditary nonpolyposis colorectal cancer (HNPCC) with reference to its clinical characteristics, diagnosis and treatment [WT5”HZ]Methods [WT5”BZ] A survey of 7 families of HNPCC patients was made [WT5”HZ] Results [WT5”BZ]Among the 7 families, 21 persons had colorectal cancer with age ranging from 26 to 79 years (average 46 years) The total of the colorectal cancer foci in 21 cases were 31,among which 16 were located proximal to,10 distal to the splenic flexure and 5 without definite record 61 5%(16/26) of the colorectal cancer foci were located proximal to the splenic flexure Six patients had multifocal colorectal cancer, which accounted for 28 6%(6/21) of all cases [WT5”HZ] Conclusions [WT5”BZ] HNPCC patients and their family members should be followed up regularly for early diagnosis and treatment of the disease and for better prognosis
ABSTRACT
Objective To investigate if the prognosis of young patients with colorectal cancer (CRC) is influenced by their familial predisposition. Methods The patients with CRC under 40 years old, underwent operation, had pathological diagnosis , family survey, followed up etc were selected into this research. According to familial predisposition they were divided into two groups: group A (with familial predisposition) and group B (without familial predisposition). Results Among the 44 patients twelve were in group A, thirty-two in group B. The 5-year survival rate in group A and B was 83.30%(10/12) and 59.38%(19/32) respectively,the difference was significant between the two groups(? 2=5.64,P
