CT腹膜癌指数对腹膜假黏液瘤可切除性价值研究

目的:探讨CT腹膜癌指数（CT-PCI）对腹膜假黏液瘤（PMP）可切除性的价值研究。方法:回顾性分析2019年1月至2020年4月航天中心医院黏液瘤科57例经手术病理证实为PMP患者的术前及术后CT图像，进行CT-PCI评分，并对术前及术后的CT-PCI评分进行统计学分析，通过CT-PCI评估手术可切除性。结果:术前CT-PCI分数较高的区域集中在0~8区，以0区为著，9~12区评分较低；术后变化最显著的区域为0区，其次是7、6和8区，9区变化最小。结论:CT-PCI可在术前明确PMP患者腹腔内肿瘤的分布及大小情况，为临床医生在术前对减瘤手术的范围提供影像学支持，可为PMP患者的减瘤程度提供初步预判，也可为PMP其他相关科学研究提供重要依据。 

Value Study of CT Peritoneal Carcinoma Index in Resectability of Pseudomyxoma Peritonei

Objective: To investigate the value of CT evaluation of peritoneal carcinoma index(CT-PCI) in the resectability of pseudomyxoma peritoneal(PMP). Methods: The preoperative and postoperative CT images of 57 patients with PMP confirmed by operation and pathology in the Department of Myxomatology of Aerospace Center Hospital from January 2019 to April 2020 were retrospectively analyzed. CT-PCI scores were performed, and the preoperative and postoperative CT-PCI scores were statistically analyzed, and the surgical resectability was evaluated by CT-PCI. Results: The regions with high preoperative CT-PCI scores were concentrated in 0-8 regions, with 0 region as the most significant and 9 ~ 12 regions as the lowest, the regions with the most significant postoperative changes were 0 region, followed by 7, 6 and 8 regions, with the smallest changes in 9 region. Conclusion: CT-PCI can determine the distribution and size of PMP tumors in the abdominal cavity before surgery, which provides an important basis for clinicians to estimate the resectability of lesions before surgery and more accurately predict the grading of postoperative tumor reduction surgery.
