Association between dietary 3-monochloropropane-1,2-diol esters (3-MCPDE) and renal cancer in Peninsular Malaysia: exposure assessment and matched case-control study.

3-Monochloropropane-1,2-diol esters (3-MCPDE) are food contaminants commonly found in refined vegetable oils and fats, which have possible carcinogenic implications in humans. To investigate this clinically, we conducted an occurrence level analysis on eight categories of retail and cooked food commonly consumed in Malaysia. This was used to estimate the daily exposure level, through a questionnaire-based case-control study involving 77 subjects with renal cancer, with 80 matching controls. Adjusted Odds Ratio (AOR) was calculated using the multiple logistic regression model adjusted for confounding factors. A pooled estimate of total 3-MCPDE intake per day was compared between both groups, to assess exposure and disease outcome. Among the food categories analysed, vegetable fats and oils recorded the highest occurrence levels (mean: 1.91 ± 1.90 mg/kg), significantly more than all other food categories (p < .05). Risk estimation found the Chinese ethnic group to be five times more likely to develop renal cancer compared to Malays (AOR = 5.15, p = .001). However, an inverse association was observed as the 3-MCPDE exposure among the Malays (median: 0.162 ± 0.229 mg/day/person) were found to be significantly higher than the Chinese (p = .001). There was no significant difference (p = .405) in 3-MCPDE intake between the cases (median: 0.115 ± 0.137 mg/day/person) and controls (median: 0.105 ± 0.151 mg/day/person), with no association between high intake of 3-MCPDE and the development of renal cancer (OR = 1.41, 95% CI: 0.5091-2.5553). Thus, there was insufficient clinical evidence to suggest that this contaminant contributes to the development of renal malignancies in humans through dietary consumption. Further research is necessary to support these findings, which could have significant public health ramifications for the improvement of dietary practices and food safety measures.

The Use of Herbal Therapy to Improve the Quality of Life among Cancer Patients in the Southern Region of Peninsular Malaysia.

OBJECTIVE: To investigate the impact of herbal therapy on the quality of life (QoL) among cancer patients and to evaluate the relationship of QoL with age, gender, cancer stage, cancer type, and history of conventional treatment. METHODOLOGY: A prospective study was targeted on cancer patients receiving herbal therapy from a Traditional and Complementary Medicine (T&CM) clinic in a public hospital from 1st January 2016 to 31st August 2018. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTCQLQ-C30) was distributed to the patients prior to herbal therapy (baseline) and after the sixth and twelfth week of herbal therapy. Socio-demographic and clinical data were collected and analyzed using SPSS version 16. RESULTS: The majority of the patients were females (60.0%) and were from the Chinese ethnic group (77.4%) with a mean age of 58.72 ± 12.17 years. Approximately 42.4% of patients were in advanced cancer stages at the time of study and 60.7% of patients had undergone radiotherapy before receiving herbal therapy. The most commonly prescribed herbs were Bai Hua She She Cao (90.6%) and Zhen Ren Huo Ming Yin (57.6%). Significant differences in mean score were observed in global health status, overall functional scales, and symptom scales after the sixth and twelfth week of receiving herbal therapy. QoL in terms of global health status and overall functional scales improved with higher scores while symptom scales recorded a lower score after twelve weeks of receiving herbal therapy in the T&CM clinic. Herbal therapy has a significant effect (p < 0.05) on the improvement of QoL of cancer patients. However, gender, cancer stage, cancer type, age, history of radiotherapy, and history of chemotherapy has no effect (p > 0.05). CONCLUSION: Herbal therapy did improve the QoL of cancer patients in the southern region of Peninsular Malaysia.
