Table 5 shows the other carcinomas included in 25 studies involving six SPSSD subtypes, namely, classic SPS (21–36), SLS (86, 90), PERM (91), progressive dizziness and unstable gait (87), and NMDAR-SPS (9). Furthermore, thyroid and renal cell cancers reportedly coexist with colon cancer and SPSSD (21). Table 4 shows that GAD65 is the most common autoantigen in patients with other carcinomas and SPSSD, followed by anti-nuclear, Ri, NCC-ST 439, amphiphysin, gephyrin, AchR, anti-islet cell, VGKC-complex, and LGI1 antigens. Here, AMPH is linked to carcinoma.
