Objective Summarize the experience in the surgical treatment of multiple original colon cancer in aged patients. Methods The retrospective analysis was performed in the 46 cases of multiple original colon cancer in aged patients in our hospital from August 1955 to May 2000. Results The 46 cases of multiple original colon cancer in aged patients account for 7.6% (46/608) of the total cases of colon cancer in patients in the same period. There were 26 cases of the male and 20 cases of the female. 30 cases were colon cancer with tumors from other organs. "The different time cancer" could be found 31 years later. The follow-up rate was 100%. The survival rates for 3,5,10,15,20 years were 71.1%(27/38), 63.6%(21/33), 43.3%(13/30), 28.6%(8/28) and 16.0%(4/25) respectively. In this study, we found that the survival rate of the group was higher than that of the aged patients suffering colon cancer in the same period of time. Conclusions The number of multiple original colon cancer in aged patients has been increased in the decade. The incidence was 43.5% (20/46) in the study. With the development of society, both doctors and patients have improved their knowledge about multiple original carcinomas in aged patients. The positive rate of early diagnosis was promoted to a high level, especially in the monitor and treatment of per operation. Choosing the energetic operation, we will acquire the better therapeutic efficacy for treatment of multiple original cancer in aged patients.

Objective To investigate the association of HLA-A and -B alleles with syphilis in Shandong Han population. Methods The allele frequencies of HLA-A and -B were detected in 205 patients with syphilis and 5844 normal human controls by PCR-sequence specific oligonucleotide probe (PCR-SSOP)method. Results The patients with syphilis showed a higher frequency of HLA-A*02, B*15, B*40 alleles(all P＜0.01, Pc＜0.05) and a lower frequency of HLA-A*26 allele (P= 0.003, Pc = 0.039) than the normal human controls did. There was an increased frequency of HLA-B*15 and B*40 alleles in patients with symptomatic syphilis (both P＜0.01, Pc＜0.05), as well as an elevated frequency of HLA-A*02, 11, 29, B*15 and 40 alleles (all P＜0.01, Pc＜0.05) and a decreased frequency of HLA-A*30 and 33 in patients with asymptomatic syphilis(P=0.002, 0.026, Pc=0.001, 0.013 respectively), compared with the normal human controls. The frequency of HLA-A*30 allele was significantly higher in patients with symptomatic syphilis than in those with asymptomatic syphilis (P = 0.001, Pc = 0.013). Conclusions There seems to be an association between HLA-A*02, B* 15 and B*40 alleles and syphilis, between HLA-A*30 allele and symptomic syphilis, and between HLA-A*02, 11 and 29 alleles and asymptom1atic syphilis, in Shandong Han population.

OBJECTIVETo seek the optimum treatment for patients with primary gastric non-Hodgkin's lymphoma and factors associated with prognosis.

METHODSA retrospective study was conducted on 157 primary gastric non-Hodgkin's lymphoma patients who had received operation for 45 years.

RESULTSThe X-ray diagnosis rate was 39.4% before operation. The diagnosis rate by gastroscopy was 52.7%. Among the 157 patients, 32 belonged to stage I(E), 40 stage II(E), 29 stage III(E), and 56 stage IV(E). All of the patients were received chemotherapy or radiation. The 3-, 5-, 10-, 15-year survival rates were 51.1% (69/135), 42.3% (55/130), 20.7% (23/111), and 13.5% (14/104).

CONCLUSIONSThe 3-, 5-year survival rates in stage I(E) and stage II(E) were 2 to 5 times higher than those in stage III(E) and IV(E) (P < 0.01). The 3-, 5-year survival rates of primary gastric non-Hodgkin's lymphoma were 60.2% (65/108) and 50.0% (52/104) respectively. The prognosis was better than the 5-year survival rate of gastric cancer patients with D(2) lymphodenectomy (33.3%). Early diagnosis and treatment are effective to prevent complications, enhance quality of patient's life, and prolong the survival.
