Methods: This analysis includes data from participants who have received at least 24 weeks ( 6 doses) of tobevibart 300 mg and elebsiran 200 mg subcutaneously every 4 weeks (Q4W) and are on nucleoside reverse transcriptase inhibitors in the ongoing MARCH, STRIVE, and THRIVE studies in participants with CHB (NCT04856085 and NCT05612581) and the SOLSTICE study in participants with CHD (NCT05461170)

Factors predictive of the presence of internal (or deep) plexiform neurofibromas have been discussed in another section, but although the majority of MPNST result from malignant transformation of plexiform neurofibromas, they can also appear on subcutaneous neurofibromas and even where there are no prior lesions.36,40,42 The molecular mechanisms of malignant transformation of neurofibromas are not well known, but mutation of the NF1 gene on both alleles in tumors, along with other epigenetic mechanisms, may lead to mutation of other important genes such as p53 and InK4A.41 Warning symptoms include sudden increase in size, change in texture (increased consistency), intense or unremitting pain, and neurological symptoms other than those usually present.40 In these cases, a radiological assessment and biopsy (with surgical resection if appropriate) should be performed immediately as a delay in diagnosis (in direct relation to the tumor size) is directly correlated to prognosis.43 It should be remembered that magnetic resonance imaging offers data on the extent and site, but not on the biological behavior of the tumor
