Purpose: Cancer in a country like Mexico is a challenge for the current health system and for public health. However, the statistics about cancer in Mexico are scarce, so epidemiologic surveillance needs to be improved. The objectives of this article were to describe the extent of cancer and to estimate the national burden of cancer through 2020. Materials and Methods: To meet this objective, an analysis of secondary official sources was performed. The cancer cases through 2020 were estimated on the basis of trends in mortality and the projection of incident cases reported by GLOBOCAN. Results: In 2013, cancer was the cause of 12.84% of all deaths in Mexico. It is projected that the prevalence of cancer will be 904,581 by 2017 and will reach 1,262,861 by early in the next decade (ie, 2020). Conclusion: Available data for cancer are incomplete. The development and implementation of population-based cancer registries in Mexico are essential. Assessment of the future outlook of cancer in Mexico will provide awareness of future challenges and can help health systems prepare to face them.

Background: Cervical cancer (CC) is a global problem; it is among the five leading causes of cancer death in women. Several studies have examined the association between age and disease prognosis; however, controversy still exists. The objective of the present study is to determine if age at diagnosis has an impact on overall survival (OS) and disease-free survival (DFS). Materials and Methods: Retrospective cohort of 2,982 patients with CC treated at the National Cancer Institute of Mexico from 2005 to 2015. We collected demographic, clinical, and treatment data, as well as current status, of 2 groups: women under and over 40 years of age. We calculated OS and DFS rates with Kaplan-Meier estimates. Cox proportional hazards modeling was used to determine risks. Results: The median follow-up time was 26.5 months (percentile [P]25–P75, 11–60.23). When comparing DFS, OS, stage, and histologic subtype between young patients 40, we did not observe any difference. We found that in both groups, locally advanced and advanced stage, neuroendocrine subtype, hydronephrosis, and positive inguinal lymph nodes increased the risks of death and recurrence. Having been pregnant was identified as protective factor in DFS (hazard ratio, 0.54; 95% confidence interval, 0.04–0.71). Conclusion: We corroborated that age at diagnosis is not a prognostic factor for decreased or increased OS or DFS, and in both groups, the stage, histologic subtype, hydronephrosis, and node involvement were identified as factors adverse to OS and DFS, and pregnancy history was a protective factor in DFS. Implications for Practice: The present study directly affects everyday clinical practice because it allows us to focus on the most relevant prognostic factors in patients with cervical cancer. When planning treatment and follow-up, clinicians should focus on stage at diagnosis, histologic subtype, hydronephrosis, and distant metastasis instead of patients’ age. They should also be aware of any previous pregnancies and poor response, or nonresponse, to treatment, which results in disease progression and persistence. Paying attention to these factors affecting overall survival and disease-free survival will help treat patients better and increase their chances of survival and improve their quality of life.

Determine the influence of nutritional counseling, exercise, access to social healthcare and drugs, and the quality of medical care on the control of diabetics. The information and blood samples were obtained in 2005. Glycemic control was defined as good if HbA1c was ≤7.0%, poor from 7.01%-9.50% and very poor if HbA1c >9.5%. Binary logistic regression models were used to determine the association of these factors with HbA1c>9.5%. Thirty percent of the patients with a medical diagnosis of diabetes had adequate metabolic control. Nutritional guidance was associated with an increase in the degree of control. A majority of diabetics have poor or very poor glycemic control. Strengthening the quality of and access to medical care for these patients is urgently needed.

Background: Screening for prostate cancer has long been a debated, complex topic. The use of risk calculators for prostate cancer is recommended for determining patients’ individual risk of cancer and the subsequent need for a prostate biopsy. These tools could lead to better discrimination of patients in need of invasive diagnostic procedures and optimized allocation of health care resources Objective: The goal of the research was to systematically review available literature on the performance of current prostate cancer risk calculators in healthy populations by comparing the relative impact of individual items on different cohorts and on the models’ overall performance. Methods: We performed a systematic review of available prostate cancer risk calculators targeted at healthy populations. We included studies published from January 2000 to March 2021 in English, Spanish, French, Portuguese, or German. Two reviewers independently decided for or against inclusion based on abstracts. A third reviewer intervened in case of disagreements. From the selected titles, we extracted information regarding the purpose of the manuscript, analyzed calculators, population for which it was calibrated, included risk factors, and the model’s overall accuracy. Results: We included a total of 18 calculators from 53 different manuscripts. The most commonly analyzed ones were the Prostate Cancer Prevention Trial (PCPT) and European Randomized Study on Prostate Cancer (ERSPC) risk calculators developed from North American and European cohorts, respectively. Both calculators provided high diagnostic ability of aggressive prostate cancer (AUC as high as 0.798 for PCPT and 0.91 for ERSPC). We found 9 calculators developed from scratch for specific populations that reached a diagnostic ability as high as 0.938. The most commonly included risk factors in the calculators were age, prostate specific antigen levels, and digital rectal examination findings. Additional calculators included race and detailed personal and family history. Conclusions: Both the PCPR and ERSPC risk calculators have been successfully adapted for cohorts other than the ones they were originally created for with no loss of diagnostic ability. Furthermore, designing calculators from scratch considering each population’s sociocultural differences has resulted in risk tools that can be well adapted to be valid in more patients. The best risk calculator for prostate cancer will be that which has been calibrated for its intended population and can be easily reproduced and implemented.

Renin-angiotensin system (RAS) in brain cancer represents a scarcely explored field in neuro-oncology. Recently, some pre- and clinical studies have reported that RAS components play a relevant role in the development and behavior of gliomas. The angiotensinogen (AGT) rs5050 genetic variant has been identified as a crucial regulator of the transcription of AGT mRNA, which makes it a logical and promising target of research. The aim of this study was to determine the relationship between the AGT rs5050 genetic variant in blood with prognosis in astrocytoma. A prospective pilot study was performed on forty-eight astrocytoma patients, who received the standard-of-care treatment. Blood samples were taken prior to surgery and DNA was sequenced using Ion Torrent next-generation sequencing and analyzed by Ion Reporter software. Descriptive, bivariate, multivariate, and survival analyses were performed using SPSS v21, STATA 12 and GraphPad Prism 7. Median follow-up was 41 months (range 1–48). Survival analysis showed a significant difference between the rs5050 genotypes (p = .05). We found lower survival rates in individuals with the GG-genotype of rs5050 AGT compared to patients with the TT- and TG-genotype (2 months vs. 11.5 months, respectively [p = .01]). In bivariate and multivariate analyses, GG-genotype was negatively associated with survival. In patients with astrocytoma, AGT rs5050 GG-genotype was associated with poor prognosis. We propose this germline genetic variant as a complementary biomarker, which can be detected practically and safely in blood samples or saliva.
