Brief summary
To study the clinical application of 99mTc-H7ND SPECT/CT imaging in the efficacy evaluation and prediction of non-small cell lung cancer (NSCLC)
Detailed description
This study was a prospective, controlled, single-center clinical study. To evaluate the value of 99mTc-H7ND imaging in the evaluation of stable disease in patients with non-small cell lung cancer (NSCLC) assessed by RECIST1.1, and to predict the efficacy of subsequent treatment (second-line treatment). Patients with NSCLC confirmed by cytology or pathology, who were unable to undergo radical surgery because of recurrence, metastasis, or their own conditions, and who had completed 2-4 cycles of first-line therapy and had RECIST1.1 assessment (SD) were divided into 2 groups: Experimental group: 99mTc-H7ND SPECT/CT imaging performed Control group: 99mTc-H7ND SPECT/CT imaging was not performed
Interventions
DIAGNOSTIC_TEST99mTc-H7ND SPECT/CT imaging performed
99mTc-H7ND SPECT/CT imaging positive (+) was defined as the presence of at least one measurable lesion and the uptake of the lesion was greater than that of normal liver in the experimental group, and patients were divided into SD+ and SD-. According to the guidelines and routine clinical practice, SD- patients were treated with the original regimen or maintenance treatment, and SD+ patients were divided into continuation of the original regimen or second-line treatment according to the MDT discussion results.
