WEST认为骨转移的效果很难评价-除非出现新的骨转,否则无法评价治疗效果
The other thing I'd say is that bone lesions (or tumors, if you'd prefer) are notoriously difficult to assess compared with nodules/tumors in soft tissues. You can see all sorts of changes in bone lesions with treatment that can be somewhere between difficult and impossible to characterize in terms of whether they're responding or progressing, so unless there are new bone lesions appearing over time, we classify bone lesions as non-measurable disease in our more standardized systems for grading whether our treatments are working. |
