Kaplan-Meier estimates of overall survival according to anti-Id immune response. (A) OS according to response to CVP chemotherapy. CR/CRu (—): n = 43; < CR/CRu (): included patients who achieved a partial response, stable disease, or progressive disease, n = 48. (B) OS in patients with (n = 33, —) or without (n = 58, ) specific anti-Id antibody production. (C) OS in patients who generated specific (n = 33, —), polyspecific (n = 14, ), or no anti-Id antibody (n = 44, ). (D) OS in patients with (n = 47, —) and without (n = 44, ) anti-Id antibody response. (E,F) Kaplan-Meier estimates of OS in patients who received hybridoma-produced idiotype vaccines. (E) OS according to anti-Id antibody response. Ab-positive (Ab pos, —), n = 33; Ab-negative (Ab neg, ), n = 28. (F) OS according to anti-Id antibody response in patients who achieved a PR to CVP chemotherapy (n = 33). Ab-positive (Ab pos, —), n = 16; Ab-negative (Ab neg, ), n = 17. sAb pos and sAb neg, with or without generating specific anti-Id response. pAb, polyspecific anti-Id response. Ab pos, patients who generated either specific or polyspecific anti-Id antibody response. Ab neg, patients who did not generate anti-Id antibody response. Definitions of specific and polyspecific antibody responses are described in “Results.”
