Abstract: An object is to provide a versatile means utilizing a probe for dPCR, which enables quick detection of a mutation relevant to a cancer. A library including a plurality of probes and/or primers or primer pairs for detecting a mutation relevant to a cancer in the DNA-binding domain of the TP53 gene is provided. By using the present invention, relapse of alimentary canal cancer after treatment can be diagnosed at an early stage. Individualized post-treatment follow-up of an alimentary canal cancer patient is also enabled.

Abstract: A compressed data patch system which stores patch data in an erasable non-volatile memory device to allow compressed data stored in a non-erasable memory device to be processed as if the compressed data was modified, thus reducing the resources and the time required for patching. To do so, compressed data 310 stored in a compressed data storing module 300 is read in response to a read request received via an external device, the compressed data is decompressed by a decompressing module 210 and is stored in a temporary storage buffer, patch data 510 stored in a patch data storing module 500 is read, and the decompressed data is patched by a patching module 400.
