Detection of minimal residual disease in acute myeloid leukemia: evaluating utility and challenges.

This study discusses the importance of minimal residual disease (MRD) detection in acute myeloid leukemia (AML) patients using liquid biopsy and next-generation sequencing (NGS). AML prognosis is based on various factors, including genetic alterations. NGS has revealed the molecular complexity of AML and helped refine risk stratification and personalized therapies. The long-term survival rates for AML patients are low, and MRD assessment is crucial in predicting prognosis. Currently, the most common methods for MRD detection are flow cytometry and quantitative PCR, but NGS is being incorporated into clinical practice due to its ability to detect genomic aberrations in the majority of AML patients. Typically, bone marrow samples are used for MRD assessment, but using peripheral blood samples or liquid biopsies would be less invasive. Leukemia originates in the bone marrow, along with the cfDNA obtained from peripheral blood. This study aimed to assess the utility of cell-free DNA (cfDNA) from peripheral blood samples for MRD detection in AML patients. A cohort of 20 AML patients was analyzed using NGS, and a correlation between MRD assessment by cfDNA and circulating tumor cells (CTCs) in paired samples was observed. Furthermore, a higher tumor signal was detected in cfDNA compared to CTCs, indicating greater sensitivity. Challenges for the application of liquid biopsy in MRD assessment were discussed, including the selection of appropriate markers and the sensitivity of certain markers. This study emphasizes the potential of liquid biopsy using cfDNA for MRD detection in AML patients and highlights the need for further research in this area.

Pain management in cervical cancer.

Cervical cancer (CC) occupies the second place in incidence and mortality among women in México. Despite this, Cervical Cancer continues to have a late diagnosis which leads to a high rate of complications. Pain represents the most feared and disabling symptom, being present in up to 86% of patients with advanced disease. The approach to managing pain in this population has not been studied and described to a full extent. In addition, there is a pressing need to provide concise recommendations to promote adequate pain control. We performed a review of the literature in CC and had experts in the field of pain management evaluate the evidence found. We then issued relevant recommendations on pharmacology and interventional pain management. Thus, the approach to pain management must be comprehensive and individualized, considering the timely and appropriate use of pharmacologic treatment as well as interventional procedures.

Effectiveness of Erector Spinae Muscle Block in Vertebral Oncologic Fracture.

Objectives An observational, retrospective, longitudinal, and analytical study aimed to evaluate the effectiveness of the erector spinae plane (ESP) block in managing pain in patients with vertebral fractures secondary to tumoral activity. This study included patients treated at the Pain Clinic who underwent ESP block. The objectives were to describe demographic characteristics, oncological diagnosis, vertebral fracture features, imaging techniques, medications used, and the level of ESP block. Additionally, pain levels were assessed using a numerical analog scale, and the consumption of opioid analgesic medications before and after the ESP block, during follow-up consultations, along with patient satisfaction. Methodology This retrospective, observational, and analytical study was conducted at the Pain Clinic of the National Cancer Institute of Mexico. Patients with vertebral fractures secondary to tumor activity were included, with data collected from March 2020 to September 2023. A consecutive non-probabilistic sampling method was employed, and specific inclusion and exclusion criteria were applied. Data were analyzed using descriptive statistics and the Wilcoxon signed-rank test for quantitative variables, with a significance level of p ≤ 0.05. IBM SPSS Statistics v. 26.0 (IBM Corp., Armonk, NY) software was utilized. Results A sample comprising 16 individuals was obtained, with an equal distribution between males and females. Fracture levels displayed variation, with L3 (12.5%) and T6 (12.5%) being the most prevalent. The ESP approach was primarily conducted using ultrasound (68.8%), while fluoroscopy and computed tomography were utilized in 25.0% and 6.3% of cases, respectively. Predominantly, methylprednisolone and ropivacaine (75.0%) were administered, with phenol used in 18.8% and a combination of methylprednisolone and bupivacaine in 6.3%. Patient satisfaction levels were reported at 81.3% (satisfied or very satisfied). Statistically significant disparities were noted between baseline and incidental pain reduction and oral opioid equivalent dosage in milligrams of morphine per day (MME/day) before and after ESP block (p ≤ 0.05). Conclusions This research provides promising preliminary evidence supporting the effectiveness of ESP block for pain management in vertebral fractures secondary to tumoral activity, enhancing the quality and safety of care for oncology patients. The absence of complications, significant improvement in pain, and reduction in opioid dependence underscore the clinical relevance of this therapeutic approach. An observational, retrospective, longitudinal, and analytical study aimed to evaluate the effectiveness of the ESP block in managing pain in patients with vertebral fractures secondary to tumoral activity. This study included patients treated at the Pain Clinic who underwent ESP block. The objectives were to describe demographic characteristics, oncological diagnosis, vertebral fracture features, imaging techniques, medications used, and the level of ESP block. Additionally, pain levels were assessed using a numerical analogue scale, and the consumption of opioid analgesic medications before and after the ESP block, during follow-up consultations, along with patient satisfaction.

Oral Manifestations in Pregnant Women: A Systematic Review.

Background: The period of pregnancy is characterized by a multitude of diverse changes that exert a notable impact on the oral cavity of women. During this gestational phase, patients necessitate tailored oral care and specific recommendations to preempt and address potential oral diseases. This systematic review aimed to perform a detailed analysis of the research studies that focused on the oral manifestations observed in pregnant women. Methods: A meticulous search was conducted in the databases Medline, Scopus, and Scielo by employing the following search terms: ((pregnant OR pregnancy)) AND (("oral manifestation*") OR ("oral health")). Articles that were published between 2013 and 2023 and written in English or Spanish and studies that scrutinized oral manifestations in pregnant women and included a diagnosis conducted by a qualified dentist were selected; we excluded articles published before 2013, articles that could not be accessed in full text, studies whose patients were not pregnant women at the time of the study, studies where patients were selected because they had a specific disease, studies where the clinical examination was not performed by a dentist, and articles written in languages other than English or Spanish. Subsequently, the risk of bias in the chosen articles was assessed in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) scale. Results: A total of 20 studies were included in the analysis, following the exclusion and inclusion criteria. These studies were categorized as cross-sectional, cohort, longitudinal, or case-control. Various oral manifestations in pregnant women were examined, with five studies comparing these manifestations with those observed in nonpregnant women. Conclusions: The most prevalent oral manifestations associated with pregnancy encompass dental caries, periodontitis, gingivitis, pyogenic granuloma, and candidiasis. Nonetheless, less common lesions may also emerge during the course of pregnancy.

The Potential Utility of 18 F-FDG PET/CT in Monitoring Corticosteroid Therapy in Inflammatory Pseudotumor.

ABSTRACT: A 69-year-old man with suspected gastrointestinal stromal tumor was referred to 18 F-FDG PET/CT. Images showed increased metabolism in a jejunal wall thickening, 2 liver lesions, and hepatic lymph nodes. The patient underwent wedge biopsy of the liver, which revealed inflammatory pseudotumor. The patient was treated with 20 mg/d prednisone, with a gradual dose reduction. A partial metabolic response was achieved after 2 months of therapy, and a final PET/CT showed complete metabolic response after 9 months. This clinical case shows the potential role of PET/CT in the assessment of the response of the inflammatory pseudotumor to corticosteroid therapy.

Bipolar radiofrequency ablation for cancer pain in the trigeminal distribution.

Tumours in patients with head and neck cancer (HNC) are associated with a more significant decrease in quality of life compared with the rest of patients with cancer. We present a patient with pain due to HNC successfully treated with bipolar radiofrequency ablation. A man in his 70s presented with a tumour in the left V2 and V3 region, with disabling pain, Visual Analogue Scale (VAS) score of 10/10, pain on swallowing, chewing and speaking, 3 months of evolution. The patient was evaluated in the pain management department, and the interventional treatment proposed consisted of bipolar pulsed radiofrequency, followed by bipolar thermal radiofrequency of the left V2 and V3 branches with fluoroscopic guidance to achieve better control and coverage of the affected trigeminal branches. Immediately after the procedure, the patient reported a significant improvement in pain with a 0-10 VAS; hypoesthesia in the affected V2 and V3 territory was identified, but no motor weakness. The improvement in pain was maintained for 6 months with a significant improvement in quality of life and pain, which allowed him to speak, chew and swallow without pain. Later, the patient died from complications associated with the disease. The treatment approach in these patients is both pain treatment and achieving independence by allowing better speech ability and improving eating, the above as a pillar of treatment focused on improving the patient's quality of life. This approach is a potential tool in the early stage of the disease in patients with pain due to HNC.

Efficacy and Safety of Celiac Plexus Neurolysis in the Treatment of Chronic Pain Secondary to Oncological Pathology of the Upper Hemiabdomen: A Systematic Review and Meta-Analysis.

Objectives: The management of chronic pain among patients with abdominal cancer is complex; against that, the neurolysis of the celiac plexus (CPN) is the best technique at the moment to determine the efficacy and safety in the treatment of chronic pain secondary to oncological pathology of the upper abdomen. Material and Methods: This was a systematic review of controlled clinical trials between 2000 and 2021, in the sources MEDLINE/PubMed, Cochrane, Scopus, Web of Science, and Google Scholar. Three independent evaluators analysed the results of the bibliographical research. The quality of the studies was assessed with the Jadad scale and the mean difference (95% confidence interval) and heterogeneity of the studies (I2) were calculated with Review Manager 5.3. Results: Seven hundred and forty-four publications were identified, including 13 studies in the qualitative synthesis and three studies in the quantitative synthesis. No difference was found in the decrease in pain intensity between 1 and 12 weeks after the intervention, comparing the experimental group with the control (P > 0.05). The adverse effects related to neurolysis were not serious and transitory, mentioning the most frequent adverse effects and reporting a percentage between 21% and 67% (with 17% for echoendoscopic neurolysis and 49% for percutaneous neurolysis). Conclusion: Celiac plexus neurolysis for the treatment of severe chronic pain secondary to oncological pathology in the upper hemiabdomen produces similar pain relief as conventional pharmacological analgesic treatment. It is a safe analgesic technique since the complications are mild and transitory.

Effect of chemotherapy on urinary volatile biomarkers for lung cancer by HS-SPME-GC-MS and chemometrics.

BACKGROUND: Volatile organic compounds (VOCs) have been studied as possible biomarkers in several diseases, including lung cancer. Early detection of cancer can improve long-term survival rates and the quality of life, so the study of VOCs in exhaled breath and urine has been increasing in recent years. This study aimed to assess the urinary VOCs that are modified after chemotherapy to identify those with the potential to be lung cancer biomarkers that can be monitored during treatment. METHODS: Three urine samples from 10 men with stage IV lung adenocarcinoma were collected, as well as urine samples from 14 men with other types of cancer (control group). All samples were analyzed by headspace-solid phase microextraction gas chromatography coupled with mass spectrometry. RESULTS: A total of 21 urinary VOCs were found with different levels after the administration of chemotherapy, with 2-pentanone being one of those that significantly decreased. Furthermore, 2-pentanone and 3-hydroxy-2,4,4-trimethylpentyl-2-methylpropanoate showed statistically significant differences with the control group. CONCLUSIONS: Chemotherapy administered to patients with advanced lung adenocarcinoma modified the volatile profile of urine. 2-Pentanone, a final product of the increased rate of fatty acid oxidation and protein hypermetabolism, significantly decreased after chemotherapy. Therefore, monitoring its urinary excretion could be very useful since its decrease over time could indicate an adequate response to chemotherapy and arrest of cancer development. Another VOC that could be a potential lung cancer biomarker is 3 hydroxy-2,4,4-trimethylpentyl-2-methylpropanoate, whose origin may be due to inhibition of the propanoic acid metabolic pathway or increased aldehyde dehydrogenase activity.

Posttranslational splicing modifications as a key mechanism in cytarabine resistance in acute myeloid leukemia.

Despite the approval of several drugs for AML, cytarabine is still widely used as a therapeutic approach. However, 85% of patients show resistance and only 10% overcome the disease. Using RNA-seq and phosphoproteomics, we show that RNA splicing and serine-arginine-rich (SR) proteins phosphorylation were altered during cytarabine resistance. Moreover, phosphorylation of SR proteins at diagnosis were significantly lower in responder than non-responder patients, pointing to their utility to predict response. These changes correlated with altered transcriptomic profiles of SR protein target genes. Notably, splicing inhibitors were therapeutically effective in treating sensitive and resistant AML cells as monotherapy or combination with other approved drugs. H3B-8800 and venetoclax combination showed the best efficacy in vitro, demonstrating synergistic effects in patient samples and no toxicity in healthy hematopoietic progenitors. Our results establish that RNA splicing inhibition, alone or combined with venetoclax, could be useful for the treatment of newly diagnosed or relapsed/refractory AML.

Computed tomography-guided Gasserian ganglion interventions for cancer-related facial pain in patients with complex anatomy: insights and recommendations.

BACKGROUND: The Gasserian ganglion is a well-known target for facial pain management, and patients with cancer present an anatomical challenge owing to tumor progression or treatment itself. Computed tomography (CT) is an alternative method for guiding these procedures. METHODS: This was an observational retrospective analysis of patients with cancer-related facial pain who underwent CT-guided Gasserian ganglion interventions using local anesthetics, local anesthetics with steroids, phenol, and radiofrequency. Demographic, clinical, and procedure-related variables were collected from January 1, 2015, to December 30, 2018, at the National Cancer Institute. Data distribution was determined using the Kolmogorov-Smirnov test. A paired sample t-test (with a cut-off of P < 0.05 for statistical significance) was used for comparing outcome. RESULTS: We observed a significant reduction in numerical rating scale (NRS) and douleur neuropathique 4 (DN4) scores from 7.6 ± 1.4 and 4.4 ± 1.4 to 3.2 ± 2.0 and 2.2 ± 1.4 points, respectively (P < 0.001). After the procedure, 70.8% of the patients were satisfied; 16.7% were very satisfied, and 12.5% were unsatisfied. No intra- or postoperative complications were observed. The most common neoplasms were head and neck tumors (83.3%). CONCLUSIONS: Our data suggest that CT guidance is an effective and safe option for managing cancer-related facial pain in patients with complex anatomy, resulting in a significant reduction in pain, high satisfaction rates, and no mechanical complications. Future research should aim to refine the role of CT guidance in multimodal pain management in this population.

Fragmentation of Care and Its Association With Survival and Costs for Patients With Breast Cancer in Colombia.

PURPOSE: Breast cancer care requires a multimodal approach and a multidisciplinary team who must work together to obtain good clinical results. The fragmentation of care can affect the breast cancer care; however, it has not been measured in a low-resource setting. The aim of this study was to identify fragmentation of care, the geographic variation of this and its association with 4-year overall survival (OS), and costs of care for patients with breast cancer enrolled in Colombia's contributory health care system. MATERIALS AND METHODS: A retrospective cohort study was conducted using administrative databases. Women with breast cancer who were treated from January 1, 2013, to December 31, 2015, were included. Fragmentation of care was the exposure, which was measured by the number of different health care provider institutions (HCPIs) that treated a patient during the first year after diagnosis. Crude mortality rates were estimated, survival functions were calculated using the nonparametric Kaplan-Meier approach, and adjusted hazard ratios (HRs) were estimated using multivariate Cox regression model to identify the association of fragmentation with 4-year OS. The association between fragmentation and costs of care was assessed using a multivariate linear regression model. RESULTS: A total of 10,999 patients with breast cancer were identified, and 1,332 deaths were observed. The 4-year crude mortality rate was 31.97 (95% CI, 30.25 to 33.69) per 1,000 person-years for the whole cohort, and the highest rate was in the cohort defined for the fourth quartile of the fragmentation measurement (eight or more HCPIs), 40.94 (95% CI, 36.49 to 45.39). The adjusted HR for 4-year OS was 1.04 (95% CI, 1.01 to 1.07) for each HCPI additional. The cost of care is increased for each additional HCPIs (cost ratio, 1.25; 95% CI, 1.23 to 1.26). CONCLUSION: Fragmentation of care decreases overall 4-year OS and increases the costs of care in women with breast cancer for Colombia.

Factors Associated with Hemodialysis Vascular Access Failure: A retrospective study in Colombia

Introduction: Vascular access (VA) remains a major source of morbidity for hemodialysis patients (HD). Few data sources adequately capture longitudinal patency of the VA. This study aimed to evaluate VA failure and its related factors in HD patients. Methods: A retrospective cohort study of 985 incident hemodialysis patients treated in clinics of BRCS in Colombia, from January 1rst ,2016, until December 3 of the same year, was done. The cohort's enrollment was on day 1 of HD, and with follow-up for up to 15 months. Association among a group of independent variables and time to failure of the VA was performed, and adjusted by baseline variables using a Cox regression model. Results: A total of 985 patients were included in the study, requiring 1774 procedures of vascular access during follow-up. The mean age was 61 ± 15.6 years. At day 1, 15 % were dialyzing with an arteriovenous fistula (AVF) or AVG; and at day 90, this proportion had increased to 70 %. The rate of vascular access procedure was 1.95 per patients-year, 95 % CI 1.86-2.04. The rate of vascular access failure was 0.66 per patients-year, 95 % CI 0.61-0.72. Risk factors for failure in AVF/AVG were age > 65 (p= 0.008), diabetes (p=0.019), female sex (p=0.002) rural housing (p<0.0001) and higher hemoglobin (p=0.021). Conclusions: Vascular access failure and the requirement for procedures associated with it are frequent in the dialysis population. Several risk factors, some of them modifiable, are related to vascular access failure.

Introducción: El acceso vascular (AV) sigue siendo una fuente importante de morbilidad para los pacientes en hemodiálisis (HD).

Métodos: Se realizó un estudio de cohorte retrospectivo de 985 pacientes incidentes a hemodiálisis tratados en clínicas de BRCS en Colombia, entre el 1ro de enero de 2016, al 31 de diciembre de 2016. La incepción de la cohorte fue el día 1 de HD y con un seguimiento de hasta 15 meses. Se realizó la asociación entre un grupo de variables independientes y el tiempo hasta la falla del AV, asimismo se ajustó por variables basales mediante un modelo de regresión de Cox. Resultados: Se incluyeron en el estudio un total de 985 pacientes que requirieron 1774 procedimientos de AV durante el seguimiento. La edad media fue de 61 ± 15,6 años. En el día 1, el 15 % se dializaba con una fístula arteriovenosa (FAV) o injerto arteriovenoso (IAV); y al día 90, esta proporción había aumentado al 70 %. La tasa de procedimiento de acceso vascular fue de 1,95 por paciente-año, IC 95 % 1,86-2,04. La tasa de falla del AV fue de 0,66 por paciente-año, IC del 95 %: 0,61-0,72. Los factores de riesgo para falla del AV en FAV/IAV fueron edad > 65 años (p= 0,008), diabetes (p= 0,019), sexo femenino (p= 0,002), vivienda rural (p<0,0001) y hemoglobina elevada (p=0,021). Conclusión: La falla del acceso vascular y el requerimiento de procedimientos asociados a ella, son frecuentes en la población en diálisis. Varios factores de riesgo, algunos de ellos modificables, están relacionados con la falla del acceso vascular.

Los cambios más notorios fueron en los ítems 18, 19 y 21, en los que para una mejor compresión de la pregunta, se identificó la necesidad de agregar determinadas expresiones o palabras. Conclusiones: se tiene disponible la versión traducida al español y adaptada culturalmente a la población colombiana del KDQ. El siguiente paso a fin de utilizar el instrumento en el país, es disponer de evidencia sobre sus propiedades clinimétricas.

Background: Considering the importance of incorporating quality of life during the care of patients with chronic kidney disease (CKD), it is necessary to have translated and cross-culturally adapted versions of different instruments designed to measure this construct. Purpose: To translate and cross-culturally adapt the Kidney Disease Questionnaire (KDQ) instrument for measuring quality of life in patients with CKD in renal failure to the Spanish spoken in Colombia. Methodology: The process was carried out following the methodology proposed by the EORTC, which includes direct translations, reverse translations and pilot test carried out in a group of patients with a diagnosis of CKD on dialysis, attended in renal units of Baxter Renal Care Services ®, in Bogota, Colombia. Results: In the process, cases were identified that required consensus to select the translation that best preserved the meaning and semantic equivalence of the instrument; differences in syntax or use of paraphrases; it was considered pertinent to make some minimal changes in the use or arrangement of prepositions or articles, so that the items and answer options would read in a more natural way; the most notorious changes were in items 18, 19 and 21, in which for a better understanding of the question, the need to add certain expressions or words was identified. Conclusions: The Spanish translated version and culturally adapted to the Colombian population of the KDQ is now available. The next step in order to use the instrument in the country is to have evidence on its clinimetric properties.

Experimental and Theoretical Studies on Acid Corrosion Inhibition of API 5L X70 Steel with Novel 1-N-α-d-Glucopyranosyl-1H-1,2,3-Triazole Xanthines.

A series of novel 1-N-α-d-glucopyranosyl-1H-1,2,3-triazole xanthines was synthesized from azido sugars (glucose, galactose, and lactose) and propargyl xanthines (theophylline and theobromine) using a typical copper (I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition. The corrosion inhibition activities of these new carbohydrate-xanthine compounds were evaluated by studying the corrosion of API 5 L X70 steel in a 1 M HCl medium. The results showed that, at 10 ppm, a 90% inhibition efficiency was reached by electrochemical impedance spectroscopy. The inhibitory efficiency of these molecules is explained by means of quantum chemical calculations of the protonated species with the solvent effect, which seems to better represent the actual situation of the experimental conditions. Some quantum chemical parameters were analyzed to characterize the inhibition performance of the tested molecules.

Real-life disease monitoring in follicular lymphoma patients using liquid biopsy ultra-deep sequencing and PET/CT.

In the present study, we screened 84 Follicular Lymphoma patients for somatic mutations suitable as liquid biopsy MRD biomarkers using a targeted next-generation sequencing (NGS) panel. We found trackable mutations in 95% of the lymph node samples and 80% of the liquid biopsy baseline samples. Then, we used an ultra-deep sequencing approach with 2 · 10-4 sensitivity (LiqBio-MRD) to track those mutations on 151 follow-up liquid biopsy samples from 54 treated patients. Positive LiqBio-MRD at first-line therapy correlated with a higher risk of progression both at the interim evaluation (HRINT 11.0, 95% CI 2.10-57.7, p = 0.005) and at the end of treatment (HREOT, HR 19.1, 95% CI 4.10-89.4, p < 0.001). Similar results were observed by PET/CT Deauville score, with a median PFS of 19 months vs. NR (p < 0.001) at the interim and 13 months vs. NR (p < 0.001) at EOT. LiqBio-MRD and PET/CT combined identified the patients that progressed in less than two years with 88% sensitivity and 100% specificity. Our results demonstrate that LiqBio-MRD is a robust and non-invasive approach, complementary to metabolic imaging, for identifying FL patients at high risk of failure during the treatment and should be considered in future response-adapted clinical trials.

A practical access for fluoroscopically-guided percutaneous sacroplasty: Case report.

BACKGROUND: Sacral metastases represent the lowest percentage of invasion to the spine, however, as chemotherapy treatments progress, the cancer survival rate has become higher, and the percentage of sacral metastases has increased. Treatment options for sacrum metastases are surgery, radiotherapy, and minimally invasive techniques such as sacroplasty and radiofrequency ablation. Knowing the repercussions that advancing the needle anteriorly (viscera) or medially (sacral roots) can have during the sacroplasty we are describing a technique to perform c-arm sacroplasty in coaxial vision, to identify the anterior sacral cortical bone that is in the limits of the pelvic viscera as well as the sacral foraminal line. CASE PRESENTATION: In the current report, we present a 75-year-old male patient with prostate cancer metastatic to S1, S2, S3 and iliac, with severe lumbar axial pain VAS 8/10. With a caudal tilt between 35-45 degrees until aligning the sacrum in a coaxial view, a 11-gauge Jamshidi needle is advanced from s3 to s1. The trajectory of the needle during the procedure is corroborated in AP and lateral, S1 is cemented, and the needle is withdrawn to cement S2 and S3. After the sacroplasty with the coaxial access, the patient reported VAS 1-2/10. CONCLUSIONS: It is important to offer an adequate quality of life to patients with sacral fractures, whether associated with cancer or sacral insufficiency fractures (SIF). Sacroplasty, being a recently described technique, can be a very viable option for these patients, that's why it is important to have safe and reliable techniques to complement the approach of this minimally invasive technique.The coaxial access may be a safe and practical way to perform sacroplasty in these patients.
