From:  Exploratory proteomic and bioinformatics analysis unveils epitope pairing between IGHV3-64 and K-Ras for polyclonal drug conjugation in colorectal cancer

 Baseline characteristics of colorectal cancer (CRC) patients and healthy controls included in the discovery-phase proteomics study.

Stage II CRC467 (55–80)2/2Limited records; no major systemic illness
Stage III CRC458 (52–67)4/0No comorbidities recorded
Stage IV CRC346 (35–60)1/2Limited records
All CRC patients1259.6 (35–80)8/4Overall, no major systemic illness was reported
Healthy controls366.7 (62–70)1/2No comorbidities

Statistical comparison: age difference between CRC patients and controls was not significant (t-test, p = 0.075). Sex distribution did not differ significantly between groups (chi-square test, p = 0.41). Comorbidity information was limited; available records did not indicate major systemic illness or medications affecting metabolic/immune function.
