Analysis of Curcumin as a Radiosensitizer in Cancer Therapy with Serum Survivin Examination: Randomised Control Trial.

OBJECTIVE: One of the important treatments for cervical cancer is radiation therapy. This study sought to determine the role of curcumin as a radio-sensitizing agent for use with radiation therapy for cervical cancer. To accomplish this, we assessed the levels of survivin, which is an anti-apoptotic protein that plays a role in cell division and apoptosis inhibition. METHOD: This study used a quasi-experimental design, including a pretest-posttest control group design approach. The study subjects included cervical carcinoma stage IIB-IIIB patients who were scheduled to undergo surgery at the Hasan Sadikin Hospital Bandung during the research period. The advanced cervical cancer patients were assigned to two groups: i) those who received curcumin + radiation therapy and ii) those who received placebo + radiation therapy. RESULTS: In the group treated with curcumin + radiation, 15 (75%) patients showed decreased survivin levels and 5 (25%) showed increased survivin levels. Whereas, in the placebo + radiation group, there were 8 (40%) patients who showed decreased survivin levels and 12 (60%) who showed increased survivin levels. CONCLUSION: In conclusion, curcumin is an effective, alternative radiosensitizer agent for application in cervical cancer treatment.

Efficacy of Oral Vitamin A in Reducing ß-hCG Levels in Low-Risk Gestational Trophoblastic Neoplasia Patients.

OBJECTIVE: Low-risk gestational trophoblastic neoplasia (GTN) is generally treated with single agent chemotherapy and methotrexate (MTX) as a first-line therapy. Vitamin A helps to increase trophoblast cell regression, as well as to decrease ß-hCG levels. Vitamin A also increases the effectiveness of MTX by inducing more malignant cell death than MTX alone. Therefore, the aim of the current study was to analyze the changes in ß-hCG levels in low-risk GTN patients following vitamin A administration. METHODS: This study was a randomized clinical trial, which examined initial serum vitamin A and ß-hCG levels in GTN patients before and after three cycles of MTX therapy. Patients were given vitamin A supplementation of 6,000 IU (1.8 mg RAEs) per day, and the changes in serum ß-hCG were observed after three cycles. Patients were grouped by ß-hCG levels (decreased or stagnant). RESULTS: A total of 32 low-risks GTN patients were divided into the intervention group (16 patients who received vitamin A supplementation) and the control group (16 patients who did not receive vitamin A supplementation). In the intervention group, the average initial ß-hCG level was 170,949.3 ± 354,452.1 mIU/mL, and the average ß-hCG post-cycle level was 1,611.9 ± 3,652.5 mIU/mL. In the control group, the average initial ß-hCG level was 178,834.1 ± 2913844.6 mIU/mL, and the average ß-hCG post-cycle level was 25,388.5 ± 58,437.7 mIU/mL. CONCLUSION: In patients with low-risk GTN who underwent MTX chemotherapy, the levels of ß-hCG and the incidence of chemo resistance in the intervention group were lower than those in the control group. Older age may also influence the incidence of chemo resistance in GTN patients. Oral administration of 6,000 IU vitamin A could help to reduce ß-hCG levels in low-risk GTN patients who receive MTX chemotherapy.
