Probiotics, as Adjuvant Therapy and Preventive Measure on Progression, and Complications of Head and Neck Cancer.

BACKGROUND: Preclinical and clinical evidence implies that destructive therapies in local and malignant tissue are frequently used on patients with head and neck cancer. Consequently, the microbiome of the treated and adjacent regions is affected. Disruption of the normal microbiome plays an important role not only in the disease progression but also in its emergence, therefore new therapies involving probiotics, prebiotics, and synbiotics have been developed to control or regulate this microbial disruption. OBJECTIVE: This review aims to describe the current and potential uses of probiotics at different stages of development of head and neck squamous cell carcinoma, as an adjuvant therapy to prevent common complications such as radiation-induced oral mucositis (RIOM) and its role in other areas. METHODS: Currently, there is no widely effective strategy to treat or prevent this kind of cancer. Surgery, radiation therapy, and chemotherapy are the three main treatments for head and neck cancer. Some therapies can also cause long-term health problems, or complications which might change the way you eat, talk, hear and breathe. RESULTS: The main uses for which probiotics have been studied are: Prevention and reduction of severity of RIOM, change in dental plaque to reduce dysbiosis, and reduction of complications in post-operated patients. Potential uses of probiotics include the reduction of disease initiation and progression by reducing local inflammation caused by bacteria and other organisms. CONCLUSION: The incidence and severity of RIOM may be lessened by probiotics. To establish its uses in additional clinical settings, though, more studies are necessary.

Liver cancer in Hidalgo State, Mexico: analysis of the status, risk factors and regional public health policy requirements: a cross-sectional correlational study.

BACKGROUND: In Latin America, liver cancer is one of the top causes of cancer mortality. It is the fifth most common cause of death among malignant tumors in Mexico and is the leading cause in Hidalgo State (43.8% of the population living in poverty). OBJECTIVE: To conduct a correlational analysis on the main risk factors for liver cancer in Hidalgo State, Mexico, including municipal disaggregation and comparison with the national level. DESIGN AND SETTING: Cross-sectional, correlational, descriptive and comparative epidemiological study using Mexican governmental databases covering 1990-2019. METHODS: A comprehensive review of the databases of the General Directorate of Health Information (DGIS) was performed to analyze official death figures, hospital discharges and national and municipal population projections, using specific search criteria defined in the Global Burden of Disease classification, based on the risk factors for liver cancer. RESULTS: Liver cancer rates showed an evident rise in Hidalgo (183%), moving from 21st place in Mexico in 1990 to 9th place in 2019. This increase was correlated with alcoholism. An increasing trend for liver cancer deaths, of 133.89%, is projected for 2030. Females and the population over 60 years of age are more affected. There are some critical regions with liver cancer death rates twice the national rate or more. CONCLUSION: Targeted effective public health strategies should be structured by identifying, characterizing and regionalizing critical marginalized municipalities that are vulnerable to alcoholism and other risk factors for liver cancer. This approach may be helpful for other states in Mexico or similar countries.
