Diffusion-weighted MRI for predicting treatment response in patients with nasopharyngeal carcinoma: a systematic review and meta-analysis

Abstract: Early prediction of treatment response in nasopharyngeal carcinoma is clinically relevant for optimizing treatment strategies. This meta-analysis was performed to evaluate whether apparent diffusion coefficient (ADC) from diffusion-weighted imaging (DWI) can predict treatment response of patients with nasopharyngeal carcinoma. A systematic search of PubMed-MEDLINE and Embase was performed to identify relevant original articles until July 22, 2021. We included studies which performed DWI for predicting locoregi… Show more

“…ADC has been proven to have good diagnostic performance in the identification of benign and malignant lesions such as the brain, thyroid, pancreas, and uterus (38)(39)(40)(41)(42). In addition, ADC has also been confirmed in other studies to better predict the response evaluation of liver cancer, nasopharyngeal cancer, colon cancer with liver metastasis after treatment (43)(44)(45). Whether the ADC value can better distinguish benign and malignant ovarian or appendages is different in some previous studies (46,47).…”

“…However, HNC is typically heterogeneous, and this heterogeneity may be due The histogram analysis of ADC values within the primary tumor has been frequently used to adaptively evaluate the heterogeneity of the primary tumor relative to the complex tumor microenvironment (11). Such analysis has proven helpful in predicting the histologic grade (23), HPV status (24), and treatment response (25,26) in patients with HNC. In the present study, although primary tumor ∆ADC mean and ∆ADC median values were higher in responders than in non-responders, which is compatible with the results of previous studies (18,20), this finding did not reach statistical significance.…”

“…To enable the derivation of analytical formulas, we will therefore restrict ourselves to the consideration of 𝛿 > 0 and the event (18). It is nevertheless possible to circumvent this simplification by numerical inversion of the relationship given in (16). But here, we will approximate…”
