Cervical cancer is preventable because the carcinogenesis is slow and there are opportunities to detect precancerous lesions by Papanicolaou (Pap) smears, colposcopy, or HPV DNA tests and to treat them by antimicrobials, surgery or cold CO2 vapourization. We have earlier reported on the chemopreventive potential of integrated treatment with antimicrobials therapy followed by a standardized oral Turmeric Oil (TO) extract upto 12 weeks in women who had persistent Low-grade Squamous Intra-epithelial Lesion (LSIL) in their Pap smears. In this communication we report their post-therapy follow up for 36 months (N = 18) with Pap smears. We were also able to follow up for 36 months control cases (N = 10) who had only standard therapy with antimicrobials.During 36 months of follow up none of the cases with integrated treatment, progressed to HSIL or cancer. Out of 15/18 cases which had a regression of Pap smear, all 15 remained free of LSIL from 6 to 36 months post-therapy showing persistent therapeutic effect of integrated therapy. In one case there was recurrence of LSIL in Pap smear, ten months post-therapy, which regressed to mild atypia after a second course of oral TO for 8 weeks.In the control group, persistence of LSIL after antimicrobials was observed in Pap smears in 5/10 cases when followed up by Pap smears up to 36 months. This preliminary report indicates some post-therapeutic benefit with integrative treatment as compared to the use of antimicrobials alone. A large scale controlled study is warranted.
Background: Prevention of cervical cancer by treatment of precancerous conditions is critical in saving lives and is cost-effective. Turmeric bio-actives have shown potential anticancer activity in vitro, in vivo and in early clinical studies. The activity and safety of non-invasive integrated treatment with antimicrobials and oral turmeric extract was explored clinically in women with Low – grade Squamous Intraepithelial Lesion (LSIL) detected in Papanicolaou (Pap) smears.Methods: Women who attended a cancer screening program and who were detected with LSIL were enrolled for the study. Treatment offered was antimicrobials for associated genital infections followed by oral turmeric extract (Curcuma longa Linn, Haldone®, 600 mg, BD) for 10 weeks. The end points for activity were the degree of abnormality in Pap smears and colposcopy, micrometry in Pap smears and serum IL-6 assays, which were carried out initially, at 4-6, and at 10-11 weeks. Safety was assessed clinically, and with blood and urine tests.Results: Out of 21 enrolled cases, 1 discontinued within 2 weeks, and 3 after 4-6 weeks, due to vaginal irritation. Out of 20 cases treated for 4-10 weeks, LSIL did not progress in any case and 18 showed regression in Pap smear scores (p<0.003; Wilcoxan Rank test); 6 showed Cervical Intraepithelial Neoplasia (CIN 1) by colposcopy initially but none post-treatment. No other significant abnormalities were observed clinically, or biochemically. Manual micrometry of Pap smears (N=17) showed a significant reduction in Nuclear diameters & Nucleus/Cytoplasmic ratio (p<0.03; paired t test). A non-significant reduction in serum IL-6 levels occurred in 5/15 cases. Post-therapy Pap smears showed persistent benefit in 16 women after 6-36 months. Conclusions: Non-invasive integrative therapy with antimicrobials followed by standardised oral turmeric extract for 10 weeks appears to be promising for LSIL management by reversing early carcinogenesis through suppression of inflammation and inhibition of NF-kB pathway.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
