In our previous randomized controlled trial (RCT), the progression/no progression of mild breast cancer-related arm lymphedema (BCRL) was examined among women randomized to a compression group (CG) with a compression sleeve (compression class (ccl) 1) or not (NCG) for 6 months. In the present prospective study, BCRL in the CG and NCG was followed for 12 months.
At the end of the RCT, 33 women with mild BCRL were eligible in the CG and 37 in the NCG. The proportional differences in no progression/progression of BCRL were defined as a >2% increase from start of RCT or exceeding 10% in the lymphedema relative volume as measured by the water displacement method. In addition, changes in the lymphedema relative volume and tissue dielectric constant ratio, which measures local tissue water, were examined. At the end of the RCT (i.e., after 6 months), a one-month break of the compression treatment was made in the CG. If the lymphedema relative volume progressed by definition, the compression treatment was resumed and continued, with follow-up of all women at 9 and 12 months.
A larger proportion of women in the NCG showed progression (57%, 61%, 67%) compared to the CG (16%, 22%, 31%) at 6, 9, and 12 months ( < 0.001, 0.005, 0.012), respectively. Twelve (33%) women in the NCG did not progress at all. No changes of the lymphedema relative volume and local tissue water were found over time at any follow-ups, but were stable on a low level.
To avoid the progression of mild BCRL into a chronic issue in the long-term, compression sleeve ccl 1 may be applied immediately after early diagnosis of mild BCRL.
在我们之前的随机对照试验(RCT)中,对随机分配至使用压力袖套(压力等级(ccl)1)的加压组(CG)或未使用压力袖套的非加压组(NCG)的女性进行了为期6个月的轻度乳腺癌相关手臂淋巴水肿(BCRL)进展/无进展情况检查。在本前瞻性研究中,对CG组和NCG组的BCRL进行了为期12个月的随访。
在RCT结束时,CG组有33例轻度BCRL女性符合条件,NCG组有37例。BCRL无进展/进展的比例差异定义为自RCT开始增加>2%或通过排水法测量的淋巴水肿相对体积超过10%。此外,还检查了淋巴水肿相对体积和测量局部组织水分的组织介电常数比的变化。在RCT结束时(即6个月后),CG组进行了为期1个月的压力治疗中断。如果淋巴水肿相对体积按定义进展,则恢复并继续压力治疗,并在9个月和12个月时对所有女性进行随访。
在6个月、9个月和12个月时,NCG组中出现进展的女性比例(分别为57%、61%、67%)高于CG组(分别为16%、22%、31%)(P<0.001、0.005、0.012)。NCG组中有12名(33%)女性根本没有进展。在任何随访中,均未发现淋巴水肿相对体积和局部组织水分随时间发生变化,但在低水平上保持稳定。
为避免轻度BCRL长期发展为慢性问题,在轻度BCRL早期诊断后可立即应用压力等级为1的压力袖套。
