Epithelial ovarian cancer (EOC) remains the most lethal of gynecological cancers. Sarcopenia and low Skeletal Muscle Radiodensity (SMD) are highly prevalent in EOC. Cross sectional imaging via MRI and CT are considered the gold standard for quantification of muscle mass and muscle density. Skeletal Muscle Index (SMI) and SMD-based thresholds for sarcopenia in EOC vary significantly and specific EOC thresholds for sarcopenia have not been defined.
Sarcopenia and low SMD are highly prevalent in EOC affecting between 11-68% and 21-35% of women, respectively. SMD may be a better prognostic biomarker in ovarian cancer than SMI. Reduced SMI and SMD may also influence the risk of postoperative complications but further studies are required. There is increasing evidence that sarcopenia increases during neoadjuvant chemotherapy.
Prehabilitation studies in surgical oncology indicate encouraging results, such as, maintenance of SMI, reduced length of stay and surgical complication rates, improved health-related quality of life and functional capacity. Early identification of body composition abnormalities would permit targeted intervention prior to, and after surgery. Cross-sectional imaging is routinely used for staging and surveillance of EOC patients and hence assessment of body composition abnormalities is possible and an underutilized resource.
上皮性卵巢癌(EOC)仍然是妇科癌症中最致命的一种。肌肉减少症和低骨骼肌放射性密度(SMD)在 EOC 中非常普遍。磁共振成像(MRI)和计算机断层扫描(CT)等横截面成像被认为是量化肌肉质量和肌肉密度的金标准。EOC 中用于肌肉减少症的骨骼肌指数(SMI)和基于 SMD 的阈值差异很大,并且尚未定义特定的 EOC 肌肉减少症阈值。
肌肉减少症和低 SMD 在 EOC 中非常普遍,分别影响 11-68%和 21-35%的女性。SMD 可能是卵巢癌比 SMI 更好的预后生物标志物。较低的 SMI 和 SMD 也可能影响术后并发症的风险,但需要进一步的研究。越来越多的证据表明,肌肉减少症在新辅助化疗期间会增加。
手术肿瘤学中的预康复研究表明了令人鼓舞的结果,例如 SMI 的维持、住院时间和手术并发症率的降低、健康相关生活质量和功能能力的提高。在手术前和手术后尽早发现身体成分异常,可以进行有针对性的干预。横截面成像通常用于 EOC 患者的分期和监测,因此评估身体成分异常是可能的,也是一种未充分利用的资源。
