CD4 lymphocytes in women with invasive and preinvasive cervical neoplasia

Gynecol Oncol. 1995 Dec;59(3):364-9. doi: 10.1006/gyno.1995.9961.


Objective: To assess the relationship between CD4 lymphocyte population and stage of disease in cervical neoplasia.

Methods: Study population was 107 women with invasive cervical cancer, 116 women with cervical intraepithelial neoplasia (CIN), and 32 women without neoplasia diagnosed in 1988-1994. All women under age 50 were seronegative for the human immunodeficiency virus (HIV). All women over age 50 with CD4:CD8 ratio below normal were HIV-negative. Stage was defined by FIGO criteria using clinical findings. CD4 and CD8 lymphocyte populations were enumerated by flow cytometry prior to treatment. The normal range of CD4 counts was defined as 537-1571 cells/mm3.

Results: Distribution of CD4 count was similar in stages I (n = 40), II (n = 24), and III (n = 32), with 31% below normal and 9% above normal (mean CD4 count = 881). However, in stage IV (n = 11), 64% were below normal and 18% above normal (mean CD4 = 591). The difference in distribution between stages I-III and stage IV was statistically significant. Among 116 CIN patients, 10% had CD4 counts below normal and 3% above normal (mean CD4 = 910). Among 32 women without cervical neoplasia, 0% had CD4 counts below normal and 3% above normal. The difference between CIN and invasive cancer in the distribution of CD4 counts and CD8 counts was significant (P < 0.01). There was no difference in the CD4 count distribution by CIN severity. Forty-five percent of patients with below-normal CD4 counts at diagnosis developed recurrent cancer compared to 43% of patients with normal or above-normal CD4 counts.

Conclusion: Women with invasive cervical cancer have lower CD4 counts and a broader distribution compared to women with preinvasive or no neoplasia. Metastatic cancer at diagnosis was associated with severely depressed CD4 count.
