Methods: Human stom- ach neoplasms model was established in nude mice. The nude mice were divided into control group, moderate-dose of rhGH group, low-dose rhGH group, 5-FU group, moderate-dose rhGH/5-FU group, and low-dose rhGH/5-FU group. The results of each group were observed after ten days. Results: After therapy, the body mass of rhGH groups was significantly increased compared with control group (P<0.05), the body mass of rhGH/5-FU groups was significantly increased compared with 5-FU group (P<0.05), but it was no significant difference between rhGH/5-FU groups and control group (P>0.05). The average tumor mass and volume of rhGH groups were not significantly increased compared with control group (P>0.05), but they were significantly reduced in 5-FU group and rhGH/5-FU groups (P<0.05). They were no significant difference between rhGH/5- FU groups and 5-FU group (P>0.05). After treatment, the percentages of S, G0/G1 and G2/M phases and proliferation index (PI) were not significantly changed in rhGH groups compared with control group (P>0.05), and the same with rhGH/5-FU groups compared with 5-FU group (P>0.05). The difference caused by dose of rhGH was not significant. Conclusion: rhGH enhances body mass, does not stimulate tumor growth, and has no adverse effects on tumor bearing nude mice. Combined with flurouracil, rhGH does not influence the efficacy of chemotherapy, and has no effect on tumor cell cycle kinetics.展开更多

Methods: Clinical data of 47 cases of uterine neoplasms occurred following radiation therapy for cervical carcinoma were retrospectively reviewed. Results: The median age at uterine neoplasms diagnosis was 62 years (range: 38-77 years), and the median latency period from initial therapy to development of uterine neoplasms was 14 years (range: 5-35 years). Thirty of 47 cases were endometrial carcinoma, of which 3 were uterine papillary serous carcinoma (UPSC). Seventeen of 47 patients were uterine sarcoma, all of those were carcinosarcoma. The distribution by stage, grade, and histology of 30 cases of endometrial carcinoma was as follows: stage Ⅰb, 1 case; stage Ⅰc, 2 cases; stage Ⅱ, 6; stage Ⅲa, 4; stage Ⅲb, 2; stage Ⅲc, 11; stage Ⅳ, 4 cases; grade 1, two cases; grade 2, nine; grade 3 (include 3 UPSC patients), seventeen; unknown grade, two; endometriod, 27; UPSC, 3 cases; 7 of 30 cases of endometrial carcinoma had recurrences (23.3%), at median time to recurrence was 24 months, and their median survival time was 26 months. The overall 3- and 5-year survival rates were 60% and 38%, respectively. Of the 17 cases of uterine sarcoma, the median survival was 10 months, 6 patients occurred recurrence (35.9%), at a median time to recurrence was 9 months, and their median survival was 6 months. The overall 3- and 5-year survival rates were 12% and 0, respectively. Conclusion: The main uterine neoplasms development after radiation therapy for cervical carcinoma is endometrial carcinomas, of which there is a preponderance of high-risk histological subtypes and a poor prognosis. Most of the uterine sarcomas occurred following radiation therapy for cervical carcinoma are carcinosarcomas and the prognosis is very poor.展开更多

文摘Objective: To investigate the effect of different doses of recombined growth hormone (rhGH) on stomach neo- plasms implanted in nude mice, and its efficacy in combining with chemotherapy (flurouracil, 5-FU). Methods: Human stom- ach neoplasms model was established in nude mice. The nude mice were divided into control group, moderate-dose of rhGH group, low-dose rhGH group, 5-FU group, moderate-dose rhGH/5-FU group, and low-dose rhGH/5-FU group. The results of each group were observed after ten days. Results: After therapy, the body mass of rhGH groups was significantly increased compared with control group (P<0.05), the body mass of rhGH/5-FU groups was significantly increased compared with 5-FU group (P<0.05), but it was no significant difference between rhGH/5-FU groups and control group (P>0.05). The average tumor mass and volume of rhGH groups were not significantly increased compared with control group (P>0.05), but they were significantly reduced in 5-FU group and rhGH/5-FU groups (P<0.05). They were no significant difference between rhGH/5- FU groups and 5-FU group (P>0.05). After treatment, the percentages of S, G0/G1 and G2/M phases and proliferation index (PI) were not significantly changed in rhGH groups compared with control group (P>0.05), and the same with rhGH/5-FU groups compared with 5-FU group (P>0.05). The difference caused by dose of rhGH was not significant. Conclusion: rhGH enhances body mass, does not stimulate tumor growth, and has no adverse effects on tumor bearing nude mice. Combined with flurouracil, rhGH does not influence the efficacy of chemotherapy, and has no effect on tumor cell cycle kinetics.
