Abstract

This retrospective study was conducted to evaluate the frequency of PET superscan in baseline staging scans of lymphoma patients.The study was conducted at the Shaukat Khanum Memorial Cancer Hospital, Lahore, from October 1, 2018 to August 31, 2019. A retrospective review of baseline PET-CT scans of 203 lymphoma patients, performed during the period of October 1, 2017 to August31,2018, was done from the institutional database. Out of these 203 patients, PET superscan pattern was observed in 13 (6.4%) patients, 08 (61.5%) males and 05 (38.5%) females. Eight (61.5%) patients had Non-Hodgkin's lymphoma, while 05 (38.5%)had Hodgkin's lymphoma. Based on TNM staging 10 (76.9%) patients had stage IV disease, 01 (07.6%) had stage III disease, and 2 (15.4%) had stage II disease. PET-CT superscan pattern is uncommon and is not dependent on the stage of the disease. It should be recognised in clinical practice as it suggests a poor prognosis.

摘要

这项回顾性研究旨在评估淋巴瘤患者基线分期扫描中 PET 超级扫描的频率。该研究于 2018 年 10 月 1 日至 2019 年 8 月 31 日在拉合尔的沙卡汗纪念癌症医院进行。对 2017 年 10 月 1 日至 2018 年 8 月 31 日期间进行的 203 例淋巴瘤患者的基线 PET-CT 扫描进行了回顾性分析，这些扫描来自机构数据库。在这 203 名患者中，有 13 名（6.4%）患者观察到 PET 超级扫描模式，其中 08 名（61.5%）为男性，05 名（38.5%）为女性。8 名（61.5%）患者患有非霍奇金淋巴瘤，而 05 名（38.5%）患有霍奇金淋巴瘤。根据 TNM 分期，10 名（76.9%）患者患有 IV 期疾病，01 名（07.6%）患者患有 III 期疾病，2 名（15.4%）患者患有 II 期疾病。PET-CT 超级扫描模式并不常见，也不依赖于疾病的阶段。在临床实践中应认识到这一点，因为它提示预后不良。
