Objective. Angiogenesis is indeed a vital process in the
progression of carcinomas, including that of larynx. Therefore,
this study (AngLaC) aimed to identify candidate angiogenesisrelated
biomarkers in laryngeal carcinoma patients.
Study Design. Prospective controlled cohort study.
Setting. Tertiary referral center.
Methods. In silico analyses of angiogenesis-related genes in
laryngeal carcinoma were performed to determine candidate
biomarkers. Serum levels of candidate biomarkers were
determined via enzyme-linked immunosorbent assay in
laryngeal carcinoma patients as well as in an age and
gender-matched control group. The associations of the
biomarkers with clinical parameters were investigated.
Results. The study included 60 laryngeal carcinoma patients
and 20 healthy controls. The serum levels of osteopontin,
IGFBP-3, VEGF, sVEGFR-1, and VEGFR-2 were significantly
higher in the patient group (p < .001, p ≤ .001, p < .001,
p < .01, p < .01, respectively). High osteopontin and sVEGFR-
1 levels were associated with locoregional-recurrence
(p = .024, p = .016, respectively). IGFBP-3 had the highest
diagnostic sensitivity (81.4%) and specificity (80%) among the
molecules that were investigated (p < .001). High sVEGFR-1
and low VEGFR-2 levels were associated with poor overallsurvival
(p = .037, p = .027, respectively). High osteopontin
and sVEGFR-1 levels were associated with poor diseasespecific
survival rates (p = .035, p = .018, respectively).
Conclusion. High serum levels of sVEGFR-1 and osteopontin
as well as low serum levels of VEGFR-2 proved to be poor
prognostic in terms of survival in laryngeal carcinoma. VEGF,
sVEGFR1, VEGFR2, IGFBP-3, and osteopontin levels were
found to be significantly increased in larynx cancer patients
compared to the normal population. Further studies on
osteopontin and sVEGFR-1 are required in order to
determine their associations with recurrence
