目的 研究新辅助化疗联合保肢手术治疗骨肉瘤的临床效果。方法 根据既往治疗骨肉瘤方法的不同,将56例患者分为对传统保肢组（A组）和现代保肢组（B组）,各28例。A组用采用传统保肢方案,即保肢手术+术后化疗方案进行;B组采用现代保肢方案,即新辅助化疗+保肢手术+术后化疗方案进行。化疗方案均采用CTX + VCR +MTX+ ADM方案,比较两组转移/复发率、术后1 年、2年及 3 年生存率、肢体功能、临床疗效情况。结果 比较两组的转移/复发率及3年后的死亡率,B组低于A组(P<0.05);肢体功能优良率及临床疗效,B组高于A组(P<0.05)。结论 新辅助化疗联合保肢手术能够降低骨肉瘤患者转移/复发率、死亡率,改善肢体功能,提高临床疗效。

Objective To study the clinical effect of neoadjuvant chemotherapy combined with limb salvage surgery for osteosarcoma. Methods Based on the previous methods of treating osteosarcoma, 56 patients were divided into the traditional limb salvage group (A group) and the modern limb salvage group (B group), 28 cases for each. The traditional limb salvage surgery + postoperative chemotherapy regimen were used in group A, and modern limb salvage regimen was performed in group B, ie neoadjuvant chemotherapy + limb salvage surgery + postoperative chemotherapy. The CTX + VCR +MTX+ ADM protocol was used in the chemotherapy regimens. The metastasis/recurrence rate, the 1-year, 2-year and 3-year survival rates, limb function, and clinical efficacy were compared between the two groups. Results The metastasis/recurrence rate and the mortality rate after 3 years in the two groups were compared. The B group was lower than that of the group A (P<0.05). The excellent rate of limb function and clinical efficacy were higher in the B group than that of in the group A (P<0.05). Conclusion Neoadjuvant chemotherapy combined with limb salvage surgery may reduce the metastasis/recurrence rate and mortality of osteosarcoma patients, improve limb function and increase clinical efficacy.

目的 探讨Bcl-2、COX-2在宫颈癌新辅助化疗前后表达的意义, 以及新辅助化疗(NACT)对宫颈癌的近期临床疗效。方法 对32例宫颈癌患者,采集NACT治疗前后的宫颈癌组织标本,采用免疫组织化学SP法检测组织中的Bcl-2及COX-2表达。结果 ①经NACT后,治疗总有效率(CR+PR)为75%,无效率(PD+SD)为25%。②宫颈癌组织中Bcl-2、COX-2的表达均出现明显下降,差异均有统计学意义(P<0.05);临床有效组中Bcl-2、COX-2的表达在NACT后出现显著下降(P<0.05),无效组中Bcl-2、COX-2的表达在NACT前后无明显统计学意义(P>0.05)。结论 Bcl-2、COX-2的表达情况对评价宫颈癌患者新辅助化疗效具有肯定的临床意义,宫颈癌行NACT后近期疗效良好。

Objective To investigate the expression of Bcl-2 and COX-2 in cervical cancer before and after neoadjuvant chemotherapy; To evaluate the efficacy of neoadjuvant chemotherapy(NACT) for cervical cancer in the recent clinical effects. Methods To select 32 cases of patients with cervical cancer, collect the cervical cancer tissues before and after NACT, immunohistochemical SP method was used to detect the expression of Bcl-2and COX-2 in the tissues. Results After neoadjuvant chemotherapy, total effective rate (CR+PR) was 75%(24/32), inefficient rate(PD+SD) was 25%(8/32). The expression of Bcl-2 and COX-2 of cervical cancer patients who had neoadjuvant chemotherapy (NACT), before and after, had great differences. The difference had statistical significance (P<0.05); The expression of Bcl-2 and COX-2 were significantly lower after neoadjuvant chemotherapy in clinical effective group(P<0.05), there is no statistical significance in clinical non-effective group(P>0.05). Conclusion The expression of Bcl-2 and COX-2 of cervical cancer patients has certain clinical significance in evaluating the effect of neoadjuvant chemotherapy in cervical cancer patients. Recent curative effect after NACT in the cervical cancer patients is good.
