ABSTRACT

BACKGROUND: The evaluation of the quality of life (QoL) of patients with colorectal cancer (CRC) is an essential measure to measure the impact of the disease and treatments on the lives of patients. However, in Latin America there is no validated and reliable instrument to assess this construct. OBJECTIVES: This study aims to validate the EORTC QLQ-CR29 instrument in the Mexican population with CRC. METHODS: This study aims to validate the EORTC QLQ-CR29 instrument in the Mexican population with CRC. The study used an instrumental design and a nonprobabilistic sample due to availability, made up of 251 patients with CRC, with an average age of 54.7 ± 12.28 years. Exploratory and confirmatory factor analyses were performed, as well as concurrent validity tests. RESULTS: The exploratory factorial analysis yielded 4 factors that explained 51.64% of the variance, with a Cronbach reliability coefficient of .766 and an Omega index of .725. The confirmatory factor analysis indicated that the proposed theoretical model fits the data almost perfectly, with an error close to 0, which shows that it is a balanced and parsimonious instrument to measure the QoL of the patients with CRC. SIGNIFICANCE OF RESULTS: The EORTC QLQ-CR29 instrument proved to be a valid and reliable instrument for use in clinical care and research directed at patients with CRC in Mexico. Its use is recommended by multidisciplinary health teams in oncology in Mexico, since it allows knowing the patient's perspective on the impact of CRC on their life, guiding therapeutic decision-making and being a primary outcome measure.

ABSTRACT

BACKGROUND: Interindividual survival and recurrence rates in cases of locoregional colon cancer following surgical resection are highly variable. The aim of the present study was to determine whether elevated pre-operative and post-operative CEA values are useful prognostic biomarkers for patients with stage I-III colon cancer who underwent surgery with curative intent. METHODS: We conducted a retrospective study in patients with histologically confirmed stage I-III primary colonic adenocarcinoma who underwent radical surgical resection at Mexico's National Cancer Institute, between January 2008 and January 2020. We determined pre-operative and post-operative CEA and analyzed the association of scores with poorer survival outcomes in patients with resected colon cancer, considering overall survival (OS) and disease-free survival (DFS). RESULTS: We included 640 patients with stage I-III colon cancer. Pre-operative CEA levels were in the normal range in 460 patients (group A) and above the reference value in the other 180. Of the latter, 134 presented normalized CEA levels after surgery, but 46 (group C) continued to show CEA levels above the reference values after surgery. Therefore, propensity score matching (PSM) was carried out to reduce the bias. Patients were adjusted at a 1:1:1 ratio with 46 in each group, to match the number in the smallest group. Median follow- up was 46.4 months (range, 4.9-147.4 months). Median DFS was significantly shorter in Group C: 55.5 months (95% CI 39.6-71.3) than in the other two groups [Group A: 77.1 months (95% CI 72.6-81.6). Group B: 75.7 months (95% CI 66.8-84.5) (p-value < 0.001)]. Overall survival was also significantly worse in group C [57.1 (95% CI 37.8-76.3) months] than in group A [82.8 (95% CI 78.6-86.9 months] and group B [87.1 (95% CI 79.6-94.5 months] (p-value = 0.002). To identify whether change in CEA levels operative and post-surgery was an independent prognostic factor for survival outcomes, a Cox proportional hazard model was applied. In multivariate analysis, change in CEA level was a statistically significant, independent prognostic factor for overall survival (p-value = 0.031). CONCLUSIONS: When assessed collectively, pre-operative and post-operative CEA values are useful biomarkers for predicting survival outcomes in patients with resected colon cancer. Prognoses are worse for patients with elevated pre-operative and post-surgical CEA values, but similar in patients with normal post-surgical values, regardless of their pre-surgery values.

ABSTRACT

BACKGROUND: After tumor resection, a preventive diverting loop ileostomy creation is a routine surgical procedure to prevent anastomotic leakage and infections and to preclude secondary surgeries. Despite its benefits, several studies have proposed potential complications that extend the disease course by impairing the feasibility of adjuvant chemotherapy and adherence. PURPOSE: The aim of this study was to evaluate the impact of ileostomy complications on the adherence to adjuvant treatment and overall survival (OS) of colon cancer (CC) patients. METHODS: Retrospective, observational study. Patients diagnosed with colon adenocarcinoma were treated between January 2010 and December 2020 at the National Cancer Institute in Mexico. STATISTICAL ANALYSIS: χ2 and t-test, Kaplan-Meier, log-rank, and Cox regression. Statistical significance differences were assessed when p was bilaterally < 0.05. RESULTS: The most frequent complications of loop-derived ileostomy were hydro-electrolytic dehydration (50%), acute kidney injury (AKI) (26%), grade 1-2 diarrhea (28%), and grade 3-4 diarrhea (21%) (p = 0.001). Patients with complete chemotherapy did not reach the median OS. In contrast, the median OS for patients with non-complete chemotherapy was 56 months (p = 0.023). Additionally, 5-year OS reached to 100% in the early restitution group, 85% in the late restitution group, and 60% in the non-restitution group (p = 0.016). Finally, AKI (p = 0.029; 95% confidence interval (CI) 3.348 [1.133-9.895]), complete chemotherapy (p = 0.028; 95% CI 0.376 [0.105-0.940]), and reversed ileostomy (p = 0.001; 95% CI 0.125 [0.038-0.407]) remained as predictors of overall survival for patients with CC treated with a loop ileostomy. CONCLUSIONS: Our results emphasize the early stoma reversal restitution as a safe and feasible alternative to prevent severe complications related to ileostomies which improve chemotherapy adherence and overall survival of colon cancer patients. This is one of the pioneer studies analyzing the impact of ileostomy on treatment adherence and outcome of Latin American patients with colon cancer. TRIAL REGISTRATION: Retrospective study No. 2021/045, in April 2021.

ABSTRACT

Purpose: Identification of patients' distress is relevant for an on-time referral to psychosocial treatment. The objective was to assess the implementation of the guidelines for distress managing in Mexican oncologists based on the NCCN guidelines.Design: The study was non-experimental and cross-sectional.Sample: Two hundred thirty-one oncologists participated with an average age of 38 ± 11 years.Methods: The likelihood of distress assessment was quantitatively evaluated.Findings: A high percentage of oncologists knew and used procedures to assess psychosocial discomfort. However, a smaller percentage used a valid and reliable instrument. Factors associated with performing distress identification procedures were knowing the distress guidelines and lack of time. Factors for questionnaire usage are the availability of brief instruments and the percentage of patients suffering from stress.Implications for Psychosocial Providers: Psychosocial providers should develop strategies to educate and ensure that oncologists are familiar with guidelines on distress in oncology. More dissemination of screening procedures and referral to psychosocial programs in oncology is required. Integrating a distress screening program involving psychosocial providers and oncologists should be approached as a routine in high-quality cancer care, to reduce the stigma associated with mental health services.

ABSTRACT

Gastrointestinal stromal tumors (GIST) account for 0.2-3% of all cancer diagnoses and are thus considered a rare type of cancer. Severe levels of fatigue occur in 33% of patients on imatinib, but besides treatment, fatigue is also associated with psychological distress. As far as we know, only one previous study has reported on the design of a psychoeducational intervention for caregivers and patients with GIST. The current study was conducted to compare the preliminary effectiveness of an Internet-delivered cognitive behavioral stress management intervention and psychoeducation program for anxiety, depression, fatigue, and quality of life in patients with gastrointestinal stromal tumors (GIST). This study had an experimental pre-test post-test design with a control group. Ninety-nine patients were randomly allocated to an Internet-delivered cognitive program (n = 50) or psychoeducation control group (n = 49). Participants completed the questionnaires at three time points (pre-test, post-test, and 3-month follow-up). Twenty-seven participants completed the intervention. A significant interaction effect between groups and time was found for general fatigue [F(2, 28) = 8.2, p < 0.001, ƞ2p = 0.25], reduced motivation [F(2, 28) = 3.5, p < 0.05, ƞ2p = 0.12], distress [F(2, 28) = 3.4, p < 0.05, ƞ2p = 0.12], and global health status [F(2, 28) = 3.8, p < 0.05, ƞ2p = 0.13]. Both intervention programs showed reductions in the dimensions of fatigue and improvements in distress and dimensions of quality of life. Additional research on a larger sample size is needed to confirm the effects obtained in this study.

ABSTRACT

Accurate load forecasting in buildings plays an important role for grid operators, demand response aggregators, building energy managers, owners, customers, etc. Probabilistic load forecasting (PLF) becomes essential to understand and manage the building's energy-saving potential. This research explains a methodology to optimize the results of a PLF using a daily characterization of the load forecast. The load forecast provided by a calibrated white-box model and a real weather forecast was classified and hierarchically selected to perform a kernel density estimation (KDE) using only similar days from the database characterized quantitatively and qualitatively. A real case study is presented to show the methodology using an office building located in Pamplona, Spain. The building monitoring, both inside-thermal sensors-and outside-weather station-is key when implementing this PLF optimization technique. The results showed that thanks to this daily characterization, it is possible to optimize the accuracy of the probabilistic load forecasting, reaching values close to 100% in some cases. In addition, the methodology explained is scalable and can be used in the initial stages of its implementation, improving the values obtained daily as the database increases with the information of each new day.

ABSTRACT

The digital world is spreading to all sectors of the economy, and Industry 4.0, with the digital twin, is a reality in the building sector. Energy reduction and decarbonization in buildings are urgently required. Models are the base for prediction and preparedness for uncertainty. Building energy models have been a growing field for a long time. This paper proposes a novel calibration methodology for a building energy model based on two pillars: simplicity, because there is an important reduction in the number of parameters (four) to be adjusted, and cost-effectiveness, because the methodology minimizes the number of sensors provided to perform the process by 47.5%. The new methodology was validated empirically and comparatively based on a previous work carried out in Annex 58 of the International Energy Agency (IEA). The use of a tested and structured experiment adds value to the results obtained.

ABSTRACT

In the current energy context of intelligent buildings and smart grids, the use of load forecasting to predict future building energy performance is becoming increasingly relevant. The prediction accuracy is directly influenced by input uncertainties such as the weather forecast, and its impact must be considered. Traditional load forecasting provides a single expected value for the predicted load and cannot properly incorporate the effect of these uncertainties. This research presents a methodology that calculates the probabilistic load forecast while accounting for the inherent uncertainty in forecast weather data. In the recent years, the probabilistic load forecasting approach has increased in importance in the literature but it is mostly focused on black-box models which do not allow performance evaluation of specific components of envelope, HVAC systems, etc. This research fills this gap using a white-box model, a building energy model (BEM) developed in EnergyPlus, to provide the probabilistic load forecast. Through a Gaussian kernel density estimation (KDE), the procedure converts the point load forecast provided by the BEM into a probabilistic load forecast based on historical data, which is provided by the building's indoor and outdoor monitoring system. An hourly map of the uncertainty of the load forecast due to the weather forecast is generated with different prediction intervals. The map provides an overview of different prediction intervals for each hour, along with the probability that the load forecast error is less than a certain value. This map can then be applied to the forecast load that is provided by the BEM by applying the prediction intervals with their associated probabilities to its outputs. The methodology was implemented and evaluated in a real school building in Denmark. The results show that the percentage of the real values that are covered by the prediction intervals for the testing month is greater than the confidence level (80%), even when a small amount of data are used for the creation of the uncertainty map; therefore, the proposed method is appropriate for predicting the probabilistic expected error in load forecasting due to the use of weather forecast data.

ABSTRACT

Metastatic, recurrent, or persistent disease in cervical cancer has a poor prognosis. Historically, this group of patients has had limited treatment options, even with the best cytotoxic treatments (platinum-based chemotherapy [CT] doublets). Therefore, investigating new medications that help improve the patient's quality of life and survival has been essential. Angiogenesis has been shown to play a critical role in tumor cell growth and survival. Bevacizumab is a recombinant humanized monoclonal G1 immunoglobulin targeted against vascular endothelial growth factor. The combination of CT and bevacizumab is associated with an increase in overall survival as well as in progression-free survival and response rates.

ABSTRACT

INTRODUCTION: The COVID-19 pandemic can have important psychosocial consequences in the population. OBJECTIVE: To determine the levels of anxiety, depression and self-care symptoms during the COVID-19 pandemic in the general population. METHOD: Online survey distributed over three weeks using a non-probability sampling. The PHQ-9 Patient Health Questionnaire, the GAD-7 Generalized Anxiety Disorder Scale and Visual analog scale for self-care behaviors were used. Between-group (anxiety and depression) descriptive and comparison analyses were carried out. RESULTS: Out of 1508 included participants, 20.8% had symptoms of severe anxiety, while 27.5% showed symptoms of severe depression. Being a woman, being single, having no children, having medical comorbidities and a history of mental health care were risk factors for developing symptoms of anxiety and depression; 66 to 80 % of the population complied with self-care recommendations. A need for receiving mental health care was identified in our study population. CONCLUSION: A larger number of individuals with moderate to severe anxiety and depression symptoms were observed than in other pandemics. COVID-19 pandemic psychological effects are considered an emerging public health problem, and implementation of programs for their care is therefore recommended.

ABSTRACT

Gastric squamous cell carcinoma (SCC) is a rare type of cancer. We report three patients with the tumor. A 65 years old male presenting with weight los and heartburn. An upper gastrointestinal endoscopy revealed an ulcerated tumor whose biopsy disclosed a gastric epidermoid carcinoma. The patient was operated and chemotherapy was attempted, but he died five months later. A 39 years old male with an antral tumor corresponding to an epidermoid carcinoma. He was operated and received chemotherapy and radiotherapy and died one year later. A 79 years old female with a distal antral tumor corresponding to a undifferentiated epidermoid carcinoma. She received palliative therapy and died two months later.

ABSTRACT

Pancreatic cancer is a malignancy of great impact in developed countries and is having an increasing impact in Latin America. Incidence and mortality rates are similar for this cancer. This is an important reason to offer to the patients the best treatments available. During the Latin American Symposium of Gastroenterology Oncology (SLAGO) held in Viña del Mar, Chile, in April 2015, a multidisciplinary group of specialists in the field met to discuss about this disease. The main conclusions of this meeting, where practitioners from most of Latin American countries participated, are listed in this consensus that seek to serve as a guide for better decision making for patients with pancreatic cancer in Latin America.

ABSTRACT

Gastrointestinal Stromal Tumors (GIST) are the most frequent mesenchymal neoplasia of the digestive tract. Genomic alterations in KIT, PDFGRA, SDH, and BRAF genes are essential in GIST oncogenesis. Therefore, the mutations in these genes have demonstrated clinical implications. Tumors with deletions in KIT-exon 11 or duplications in exon 9 are associated with a worse prognosis. In contrast, KIT-exon 11 substitutions and duplications are associated with a better clinical outcome. Moreover, mutations in Kit exon 9 and 11 are actionable, due to their response to imatinib, while mutations in PDGFRA respond to sunitinib and/or avapritinib. Although, molecular testing on tissue samples is effective; it is invasive, requires adequate amounts of tissue, and a long experimental process is needed for results. In contrast, liquid biopsy has been proposed as a simple and non-invasive method to test biomarkers in cancer. The most common molecule analyzed by liquid biopsy is circulating tumor DNA (ctDNA). GISTs ctDNA testing has been demonstrated to be effective in identifying known and novel KIT mutations that were not detected using traditional tissue DNA testing and have been useful in determining progression risk and response to TKI therapy. This allows the clinician to have an accurate picture of the genetic changes of the tumor over time. In this work, we aimed to discuss the implications of mutational testing in clinical outcomes, the methods to test ctDNA and the future challenges in the establishment of alternatives of personalized medicine.

ABSTRACT

Mexican specialists in oncology, oncologic surgery, thoracic surgery, pneumology, pathology, molecular biology, anesthesiology, algology, psychology, nutrition, and rehabilitation (all of them experts in lung cancer treatment) in order to develop the National Consensus on Lung Cancer. The consensus has been developed as an answer to the need of updated Mexican guidelines for the optimal treatment of the disease, as well as to the requirements that such guidelines be established by multidisciplinary panel, depicting the current attention given to cancer lung cases in Mexico. Thus, this paper analyses the epidemiological review, screening, diagnosis, staging, pathology, translational medicine, and the suitable therapies for early, locally advanced, and metastatic disease in the first, second, and third lines of management, as well as rehabilitation and palliative measures.

ABSTRACT

Background: Incidence of young patients (aged 40 years or younger) diagnosed with gastric carcinoma has increased worldwide. Young GC diagnosis, have clinicopathological features that differ from elderly, and is correlated with bad prognosis factors. The purpose of this work is to describe the prevalence, clinic-pathological features, and prognosis of overall survival (OS) of young Latin-American patients with GC. Methods: Retrospective, observational study. Included patients treated at the National Cancer Institute [2004-2020]. Statistical analysis: χ2 and t-test, Kaplan-Meier, Log-Rank and Cox-Regression. Statistical significance differences were assessed when P was bilaterally <0.05. Results: A total of 2,543 patients fulfilled the inclusion criteria. Young-patients were predominantly female (54%), with diffuse-type adenocarcinoma (68%), signet-ring-cell (72%), poor-differentiation (90%), and metastatic (79%). In OS analysis, patients with metastatic disease, showed differences regarding age, young patients reported a median-OS of 8 versus 13 months for elderly patients (P=0.001). Among young patients, differences were also observed regarding gender, young-female patients had a median-OS of 5 versus 11 months for young-man (P=0.001). Conclusions: This is one of the pioneer studies correlating age with gender and the prognostic features of bad prognosis in Latin-American population. Besides, supports the idea that a global effort is required to improve awareness, prevention, and early diagnosis of GC.

ABSTRACT

To establish the severity of pancreatitis, there are many scoring systems, the most used are the Marshall and APACHE II systems, each one has advantages and disadvantages; but with good relation regarding mortality and prediction of complications. In populations with low barometric pressures produced by a decrease in atmospheric pressure, there is a decrease in partial pressure of oxygen, in these cases scores which take arterial oxygen partial pressure as one of their variables, may be overestimated. A diagnostic trial study was designed to evaluate the performance of APACHE II, Marshall and BISAP in a city 2640 m above sea level. A ROC analysis was performed to estimate the AUC of each of the scores, to evaluate the performance in predicting unfavorable outcomes (defined as the need for percutaneous drainage, surgery, or mortality) and a non-parametric comparison was made between the AUC of each of the scores with the DeLong test. From January 2018 to December 2019, data from 424 patients living in Bogota, with a diagnosis of gallstone pancreatitis was collected consecutively in a hospital in Bogota, Colombia. The ROC analysis showed AUC for predicting adverse outcomes for APACHE II in 0.738 (95% CI 0.647-0.829), Marshall in 0.650 (95% CI 0.554-0.746), and BISAP in 0.744 (95% CI 0.654-0.835). The non-parametric comparison to assess whether there were differences between the different AUC of the different scores showed that there is a statistically significant difference between Marshall and BISAP AUC to predict unfavorable outcomes (p=0.032). The mortality in the group of patients studied was 5.8%. We suggest the use of BISAP to predict clinical outcomes in patients with a diagnosis of biliary pancreatitis in populations with decreased atmospheric pressure because it is an easy-to-use tool and does not require arterial oxygen partial pressure for its calculation.

ABSTRACT

Background: Survival and recurrence rates following locoregional colon cancer surgical resection are highly variable. Currently used tools to assess patient risk are still imperfect. In the present work, we evaluate, for the first time, the prognostic value of the recently developed HALP (hemoglobin, albumin, lymphocyte, and platelet) index in Hispanic colon cancer patients. Patients and Methods. We conducted a retrospective cohort study in Mexican patients with a nonmetastatic colon cancer diagnosis who underwent surgical resection. We determined the preoperative HALP score optimal cut-off value by using the X-tile software. We plotted survival curves using the Kaplan-Meier method and performed a multivariate Cox regression analysis to explore the association of preoperative HALP score with two primary endpoints: overall survival (OS) and disease-free survival (DFS). Results: We included 640 patients (49.8% female). The optimal HALP cut-off value was 15.0. A low HALP index was statistically significantly associated with a higher TNM stage. Low HALP score was statistically significantly associated with shorter median OS in the Kaplan-Meier analysis (73.5 vs. 84.8 months) and in the multivariate Cox regression analysis (HR = 1.942, 95% CI = 1.647-2.875). There was no significant association between the HALP score and DFS. Conclusions: Our findings show that the HALP index is an independent factor associated with survival in Hispanic patients, despite recurrence. It seems to reflect both the anatomical extent of the disease and traditionally unaccounted nutritional and inflammatory factors that are significant for prognosis.
