Abstract
BACKGROUND With rising rates of complementary and alternative medicine use, the exploration of complementary and alternative medicine integration into oncology treatments is becoming increasingly prevalent. Vitamin B compounds including B1, B2, B3, B5, B6, B9, and B12, have all been proposed as potentially beneficial in cancer prevention and treatment as well as side effect management; however, many studies contain contradicting evidence regarding the utility of B vitamins within oncology. Thus, the aim of this study was to evaluate the safety and efficacy of Vitamin B supplementation in the oncology setting. DESIGN A systematic review was conducted following The Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Reviews guidelines, using pre-specified search terms in PubMed to include randomized control trials, clinical trials, and case studies. Two reviewers independently reviewed titles, abstracts, and full-text articles for inclusion, with a third reviewer resolving conflicts, before the included articles underwent data extraction and quality appraisal. Data extraction was conducted through COVIDENCE, which was used to manage and track the data during the search process. RESULTS Out of 694 articles initially identified, 25 articles met the inclusion criteria and were included in the review. Designs of the studies varied, including randomized control trials, clinical trials, and case/cohort studies. The impact of vitamin supplementation on cancer risk varied. Several studies found that certain B vitamin supplementation lowered cancer risk: B9 and B6 in nasopharyngeal carcinoma (n = 1200 patients) and in pancreatic cancer (n = 258 patients); B3 in hepatocellular carcinoma (n = 494,860 patients); B6 in breast cancer (n = 27,853 patients); and B9 in BRCA1-positive breast cancer (n = 400 patients). However, some studies found that certain B vitamin supplementation increased the risk or negative outcomes of cancer: B6 during nasopharyngeal carcinoma treatment (n = 592 patients); B6 in risk of hepatocellular carcinoma (n = 494,860 patients); and B9 plasma levels in breast cancer (n = 164 patients). Due to the many adverse effects that occur in cancer treatment, the effectiveness of Vitamin B supplementation in alleviating adverse effects was evaluated. In two separate studies, Vitamin B6 and Vitamin B12 supplementation with acupuncture was found to be effective as adjunct therapies aimed to reduce chemotherapy-induced peripheral neuropathy (n = 23 patients and n = 104 patients, respectively). No significant findings were established regarding B vitamin supplementation in chemotherapy-induced hand-foot syndrome. CONCLUSIONS In this systematic review we concluded that B vitamin supplements have varying data regarding safety and efficacy in cancer. Taking into account the etiology of the cancer, the specific B-vitamin, and the presence of any side effects could help guide utilization of the data found in this review. Large, randomized controlled trials are needed to confirm these findings among various cancer diagnoses and stages. Given the widespread utilization of supplements, healthcare providers should understand the safety and efficacy of vitamin B supplementation to address questions that arise in caring for those with cancer.

Abstract
•Is the Index of Nutritional Quality (INQ) associated with colon cancer? •This study compared the INQ of various dietary components between colorectal cancer patients and healthy controls. A total of 480 participants were enrolled in the study (160 patients with colorectal cancer as a case group and 320 healthy control). The results showed that CRC is significantly associated with INQ for some micronutrients. INQ can be considered as an indicator to assess clinical nutritional problems. Background - The nutritional quality of diet may influence the risk of colorectal cancer (CRC). This study compared the Index of Nutritional Quality (INQ) of various dietary components between colorectal cancer patients and healthy controls. Methods - A total of 480 participants were enrolled in the study (160 patients with colorectal cancer as a case group and 320 healthy control). An analysis was conducted on the general characteristics of the participants, their medical histories, anthropometric indicators, physical activity, alcohol consumption, reproductive history, smoking and food intake. A valid food frequency questionnaire was used to assess nutrient intake and INQ was calculated from daily nutrient intake. Results - A Significant inverse association was found between CRC and INQ for vitamins A (OR=0.01, CI: 0.01-0.01), K (OR=0.04, CI: 0.01-0.15), and B12 (OR=0.71, CI: 0.51-0.98), B5 (OR=0.43, CI: 0.00-0.01), zinc (OR=0.35, CI: 0.13-0.95), and phosphorus (OR=0.17, 0.19-0.94). The association between the INQ of vitamin B12 and zinc with colorectal cancer was disappeared after age adjustment. There was a significant negative association between CRC with the INQ of vitamins A, K, B5, phosphorus, and calcium after further adjustments for gender, BMI, menopausal status, and total energy intake. Conclusion -CRC is significantly associated with INQ for some micronutrients. INQ can be considered as an indicator to assess clinical nutritional problems.

Gamma-ray Irradiation of Rodent Diets Alters the Urinary Metabolome in Rats with Chemically Induced Mammary Cancer. Metabolites 2022; 12:metabo12100976. [PMID: 36295878 PMCID: PMC9608802 DOI: 10.3390/metabo12100976] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 10/13/2022] [Accepted: 10/14/2022] [Indexed: 11/30/2022] Open
Abstract
In this study, a comparative, untargeted metabolomics approach was applied to compare urinary metabolite profiles of rats fed irradiated and non-irradiated diets. γ-Irradiated and non-irradiated NIH 7001 diet was given orally to animals beginning 5 days after exposure to the carcinogen N-methyl-N-nitrosourea and continued for 120 days. There was a 36% reduction in mammary tumor incidence in rats consuming the γ-irradiated diet, compared to rats receiving the non-irradiated form of the same diet. Urine samples from rats fed with γ-irradiated and non-irradiated diets were analyzed using nanoLC-MS/MS on a Q-TOF mass spectrometer, collecting positive and negative ion data. Data processing involved feature detection and alignment with MS-DIAL, normalization, mean-centering and Pareto scaling, and univariate and multivariate statistical analysis using MetaboAnalyst, and pathway analysis with Mummichog. Unsupervised Principal Component Analysis and supervised Partial Least Squares-Discriminant Analysis of both negative and positive ions revealed separation of the two groups. The top 25 metabolites from variable importance in projection scores >1 showed their contributions in discriminating urines the γ-irradiated diet fed group from non-irradiated control diet group. Consumption of the γ-irradiated diet led to alteration of several gut microbial metabolites such as phenylacetylglycine, indoxyl sulfate, kynurenic acid, hippurate and betaine in the urine. This study provides insights into metabolic changes in rat urine in response to a γ-irradiated diet which may be associated with mammary cancer prevention.

Nutrients 2022; 14:nu14132644. [PMID: 35807825 PMCID: PMC9268499 DOI: 10.3390/nu14132644] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 06/20/2022] [Accepted: 06/24/2022] [Indexed: 02/07/2023] Open
Abstract
This study investigated the association between micronutrient intake and breast cancer risk in South Korean adult women. This association was stratified according to body mass index (BMI) categories. Data from the Korean Genome and Epidemiology Study (KoGES) and the Health Examinee Study were analyzed. Altogether, 63,337 individuals (aged ≥40 years) completed the baseline and first follow-up surveys; 40,432 women without a history of cancer at baseline were included in this study. The association between micronutrient intake and breast cancer was determined by estimating the hazard ratio (HR) and 95% confidence interval (CI) using the Cox proportional hazard regression model. A stratified analysis by BMI (<25 kg/m2 and ≥25 kg/m2) was performed. The an analysis of 15 micronutrients and breast cancer risk revealed that none of the micronutrients were associated with breast cancer risk after adjusting for covariates. In obese women, the risk of breast cancer was significantly reduced in the group that consumed vitamin C more than the recommended level (HR = 0.54, 95% CI: 0.31−0.93) and vitamin B6 levels above the recommended level (HR = 0.48, 95% CI: 0.25−0.89). In obese women, exceeding the recommended daily intake levels of vitamin C and vitamin B6 was associated with a lower risk of breast cancer. However, other micronutrients were not associated with breast cancer risk in these women.

Abstract
The malignant neoplastic cell is characterized by its diverse metabolic changes. It occurs in order to maintain the high rate of proliferation. The possibility of new pharmacological targets has inserted tumor metabolism as a target for recent research, emphasizing the enzymatic activity of thiamin. This review aims to elucidate the behavior of thiamin against tumor development. This is a systematic review in which studies indexed in Pubmed, Scopus, SciELO and BVS were searched using the descriptors (Thiamin OR Vitamin B1) AND (Cancer OR Malignant neoplasia) AND (Tumor metabolism). Title and abstract were read. Duplicates, literary reviews, books, conference abstracts, editorials, and papers published prior to 2010 were eliminated. 23 records were included in this review. Low doses of thiamin have been shown to be enough to stimulate tumor growth. Another population studies has shown evidence of tumor regression after correction of vitamin B1 deficiency. There is an open path for the development of new research to better assess the influence of thiamin on cancer cells. Once the connections between thiamin and the metabolism of cancer cells are fully established, new opportunities for therapeutic intervention and dietary modification will appear to reduce the progression of the disease in patients with cancer.

Abstract
Background recently, many researches have concentrated on the relevance between N1-methyladenosine (m1A) methylation modifications and tumor progression and prognosis. However, it remains unknown whether m1A modification has an effect in the prognosis of ovarian cancer (OC) and its immune infiltration. Methods Based on 10 m1A modulators, we comprehensively assessed m1A modification patterns in 474 OC patients and linked them to TME immune infiltration characteristics. m1Ascore computed with principal component analysis algorithm was applied to quantify m1A modification pattern in OC patients. m1A regulators protein and mRNA expression were respectively obtained by HPA website and RT-PCR in clinical OC and normal samples. Results We finally identified three different m1A modification patterns. The immune infiltration features of these m1A modification patterns correspond to three tumor immune phenotypes, including immune-desert, immune-inflamed and immune-excluded phenotypes. The results demonstrate individual tumor m1A modification patterns can predict patient survival, stage and grade. The m1Ascore was calculated to quantify individual OC patient's m1A modification pattern. A high m1Ascore is usually accompanied by a better survival advantage and a lower mutational load. Research on m1Ascore in the treatment of OC patients showed that patients with high m1Ascore showed marked therapeutic benefits and clinical outcomes in terms of chemotherapy and immunotherapy. Lastly, we obtained four small molecule drugs that may potentially ameliorate prognosis. Conclusion This research demonstrates that m1A methylation modification makes an essential function in the prognosis of OC and in shaping the immune microenvironment. Comprehensive evaluation of m1A modifications improves our knowledge of immune infiltration profile and provides a more efficient individualized immunotherapy strategy for OC patients.

Abstract
BACKGROUND Hepatocellular carcinoma develops in some patients with hepatitis C virus (HCV), even after achieving sustained virological response (SVR). AIMS We examined factors associated with liver disease progression in a prospective cohort study of SVR patients. METHODS Participants were patients who had visited a hospital for clinical follow-up of chronic HCV infection in 2005 and had reached SVR as a result of subsequent antiviral treatment. Baseline information including lifestyle and dietary habits before SVR was collected in 2005 using self-administered questionnaires, and clinical information before SVR was collected from medical records in 2005. Study outcome was liver disease progression such as liver cirrhosis, hepatocellular carcinoma, and/or liver disease-related death after SVR. Proportional hazard models were employed to calculate hazard ratios (HRs) and 95% confidence intervals for each variable. RESULTS Of 180 SVR patients, 27 patients (15%) showed liver disease progression after SVR: 26 (14%) were diagnosed with liver cirrhosis, two (1%) with hepatocellular carcinoma, and/or one (0.6%) with liver-disease-related death. Besides older age at SVR (HR = 11.9, P < 0.01) and aspartate aminotransferase-to-platelet ratio index score ≥ 1.0 before SVR (HR = 2.63, P = 0.03), alcohol drinkers before SVR (HR = 2.82, P = 0.06) were suggested to be associated with liver disease progression after SVR, whereas higher consumption of vitamin B12 before SVR showed a decreased HR for liver disease progression (HR = 0.41, P = 0.09). CONCLUSIONS Alcohol drinking might be associated with liver disease progression, whereas vitamin B12 intake might have protective effects against liver disease progression after eradication of HCV. Further studies are needed to confirm these findings.

Abstract
Epidemiological studies showing the correlation between folate and the breast cancer risk have revealed inconsistent results. Hence, we conducted a dose-response meta-analysis of observational studies to obtain more reliable conclusions. We searched PubMed and Embase for studies published before April 2019 and identified 39 studies on folate intake and 12 studies on plasma folate level. The combined odds ratios (ORs) and 95% confidence intervals (CIs) were extracted to estimate the breast cancer risk. Folate intake was inversely correlated with the breast cancer risk when the highest and lowest categories (OR = 0.85, 95% CI = 0.79-0.92) were compared, and the dose-response result showed that folate intake had a linear correlation with the breast cancer risk. Moreover, a higher folate intake correlated with a lower breast cancer risk in premenopausal women (OR = 0.80, 95% CI = 0.66-0.97), but not in postmenopausal women (OR = 0.94, 95% CI = 0.83-1.06). However, plasma folate levels were not correlated with the breast cancer risk (OR = 0.98, 95% CI = 0.82-1.17). Folate intake was negatively correlated with the breast cancer risk; however, its practical clinical significance requires further study. Furthermore, additional folate supplements should be considered carefully.

Clin Breast Cancer 2020; 20:e469-e480. [PMID: 32241696 DOI: 10.1016/j.clbc.2020.02.012] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Revised: 02/15/2020] [Accepted: 02/20/2020] [Indexed: 02/06/2023]
Abstract
Epidemiologic studies focusing on the association between 1-carbon metabolism-related vitamins (ie, folate, vitamin B6, vitamin B2, vitamin B12) and breast cancer risk have reported inconsistent findings. We conducted a systematic search of the reported data and performed a meta-analysis of prospective case-control and cohort studies to derive a more precise evaluation. The PubMed and EMBASE databases were searched to identify eligible studies. A total of 27 studies involving 49,707 cases and 1,274,060 individuals were included in the meta-analysis. The results indicated that a high intake of folate, vitamin B6, and vitamin B2 might decrease the risk of breast cancer. The corresponding pooled relative risks (RRs) for the highest intake compared with the lowest were 0.93 (95% confidence interval [CI], 0.88-0.99; P = .018), 0.94 (95% CI, 0.89-1.00; P = .037) and 0.90 (95% CI, 0.82-0.99; P = .026). No significant association between vitamin B12 and breast cancer risk was found (RR, 0.99; 95% CI, 0.94-1.04; P = .604). Further study showed that folate and vitamin B6 might decrease the risk of estrogen receptor-negative (ER-)/progesterone receptor-negative (PR-) breast cancer but not ER+/PR+ breast cancer. The dose-response meta-analysis indicated a significant linearity relationship between folate intake and a reduced risk of ER-/PR- breast cancer. An increment of folate intake (100 μg/d) corresponded to a 7% deceased risk of ER-/PR- breast cancer (RR, 0.93; 95% CI, 0.89-0.98; P = .007). In conclusion, a high intake of 1-carbon metabolism-related vitamins might contribute to the prevention of breast cancer, especially ER-/PR- breast cancer.

Abstract
Few studies have explored the associations of thiamin, niacin and riboflavin with risk of cancer despite their role in potentially cancer-associated one-carbon metabolism. Using multivariable Cox proportional hazards regression models modified for the case-cohort design, we examined the associations of dietary intake of the above-mentioned B vitamins, as well as folate, and vitamins B6 and B12, with risk of the breast (n = 922), endometrial (n = 180), ovarian (n = 104) and colorectal (n = 266) cancers among age-stratified subcohorts of 3,185 women who were randomly selected from a cohort of 73,909 participants. None of the B-vitamins were associated with risk of breast or colorectal cancers. However, relatively high dietary intake of folate intake was inversely associated with risk of endometrial (HRq4 vs q1: 0.52; 95% CI: 0.29-0.93) and ovarian (HRq3 vs q1: 0.39; 95% CI: 0.19-0.80) cancers while relatively high dietary intake of vitamin B6 was inversely associated with ovarian cancer risk (HRq3 vs q1: 0.49; 95% CI: 0.24-0.98). These findings suggest that dietary intake of folate may reduce risk of endometrial and ovarian cancers and dietary intake of vitamin B6 may reduce risk of ovarian cancer.

Abstract
PURPOSE OF REVIEW To synthesize the critical role of obesity-associated inflammation, dietary factors, and nutrition in determining breast cancer risk. RECENT FINDINGS Obesity-associated inflammation is strongly linked to breast cancer risk and progression, largely via two processes: inflammatory pathways and dysregulated metabolism. Cytokine production in excess adipose tissues creates a chronic inflammatory microenvironment, which favors tumor development. Lifestyle factors, including diet, have long been recognized as important determinants of breast cancer risk and mortality. SUMMARY Obesity increases the risk of developing breast cancer in both pre- and postmenopausal women and also negatively affects breast cancer recurrence and survival. Poor dietary habits characterized by the high intake of refined starches, sugar, and both saturated and trans-saturated fats, as well as the low intake of omega-3 fatty acids, natural antioxidants, and fiber, modulate inflammation and, thereby, appear to be linked to increased risk of breast cancer and mortality.
