Application of PETCT in Radiotherapy of Patients with Peritoneal Lymph Node Metastasis from Cervical Cancer

Abstract

Objective To observe the value of positron emission computed tomography (PET CT) in radiotherapy of patients with peritoneal lymph node metastasis from cervical cancer. Methods 72 patients with peritoneal lymph node metastasis of cervical cancer admitted to our hospital from March 2018 to March 2019 were selected as the study objects. They were randomly divided into the control group (CT guided radiotherapy) and the observation group (PETCT guided radiotherapy) according to the admission sequence, with 36 cases in each group. The relevant indicators, short-term efficacy and adverse reactions of the two groups were compared. Results GTVnd, CTV, PTV in the observation group were significantly larger than those in the control group (P<0.05), and there was no significant difference between the two groups in PGTVnd (P>0.05); The total effective rate of short-term chemotherapy in the observation group was significantly higher than that in the control group (86.11% vs 70.73%, P<0.05), and there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusion PETCT has a clear advantage in radiotherapy for patients with peritoneal lymph node metastasis of cervical cancer, and it can accurately locate the metastatic lymph nodes to improve the efficacy of radiotherapy, with good safety.
