Metastatic Pancreatic Cancer: Where Are We?

Pancreatic cancer is one of the most lethal neoplasms worldwide; it is aggressive in nature and has a poor prognosis. The overall survival rate for pancreatic cancer is low. Most patients present non-specific symptoms in the advanced stages, which generally leads to late diagnosis, at which point there is no option for curative surgery. The treatment of metastatic pancreatic cancer includes systemic therapy, in some cases radiotherapy, and more recently, molecular targeted therapies, which can positively impact cancer control and improve quality of life. This review provides an overview of the molecular landscape of pancreatic cancer based on the most recent literature, as well as current treatment options for patients with metastatic pancreatic cancer.

Painful shoulder and scapula as initial presentation of advanced lung adenocarcinoma.

Lung adenocarcinoma is a common cancer; even though it has a strong association with previous smoking, there has been described nonsmokers-related cases. Symptoms varies from asymptomatic to hemoptysis or pleural effusion. We describe a case of a patient who presented with painful scapula as primary manifestation of advanced pulmonary malignancy.

Sexual dysfunction as a challenge in treated breast cancer: in-depth analysis and risk assessment to improve individual outcomes.

The increasing number of breast cancer survivors has led to a greater emphasis on issues related to quality of life (QoL). Up to 75% of women treated for breast cancer (BC) report sexual disorders. However, most oncologists are not trained to recognize which patients are at high-risk of developing sexual disorders. Female sexual dysfunction (FSD) is common in patients with BC; we found that patients without FSD prior to BC treatment are at risk of developing FSD after treatment. Treatment of early BC relies on the combination of chemotherapy, surgery, and radiation therapy. All these treatments have side effects or sequelae identified as high-risk factors for the development of FSD. The choice of less toxic treatments in each modality could reduce the risk of FSD in some cases, without affecting the risk of recurrence or effectiveness. A comprehensive approach of BC must consider FSD as a determinant factor of QoL in survivors.

Asbestos and cancer in Latin America and the Caribbean: we may have won some battles, but definitely not the war.

Only six countries have banned the industrial use of asbestos in Latin America and the Caribbean. In fact, the industrial use of asbestos appears to be growing in this region. Asbestos is one of the most dangerous natural substances in the world, it is contained in several types of rocks (such as serpentinites, mafic and ultramafic rocks) but fibers can be released to the atmosphere both by natural and antropogenic sources. Six countries have banned the industrial use of asbestos in this region, we expected that laws established before 2007 would be less adherent to the 2007 WHO/ILO recommendations. In contrast, the Chilean law of 2001 is one of those that most adheres to international recommendations along with the Colombian law of 2021. Which means that the newest laws are not necessarily the strongest. This article aims to draw a regional overview of the laws against asbestos production in Latin America and the Caribbean, highlighting the strengths and weaknesses of each national policy. We recommend that countries that have already banned asbestos consider updating and strengthening their existing laws and develop clinical guidelines for the management, monitoring, and rehabilitation of asbestos-related diseases. The challenge of asbestos goes far beyond a prohibition law.

Sedación paliativa en enfermedad terminal / Palliative sedation in terminal desease

Resumen Algunos pacientes con enfermedad terminal que están cerca del final de la vida pueden experimentar un sufrimiento intolerable dado por síntomas refractarios a las terapias paliativas específicas. La Sedación Paliativa (SP) se considera una modalidad de tratamiento eficaz para el manejo de estos síntomas refractarios cuando los esfuerzos agresivos no proporcionan alivio. La SP consiste en el uso de medicamentos que inducen sedación y disminución del nivel de conciencia con el objetivo de aliviar el sufrimiento intolerable en los últimos días de la vida. Los síntomas físicos refractarios más frecuentes son el dolor, delirium y disnea, sin embargo, la SP también se indica para tratar el sufrimiento existencial o la angustia psicológica, que es un problema extremadamente difícil y delicado. La SP ha sido ampliamente debatida por las obvias implicaciones éticas, socioculturales y de toma de decisiones. Se ha reportado que la SP se administra en una proporción que va del 2% al 52% de los pacientes con enfermedades terminales. Los estudios han sugerido que la SP es exitosa en el manejo de los síntomas intratables al final de la vida, no genera efectos perjudiciales sobre la supervivencia y es satisfactoria para los familiares.

Abstract Palliative sedation (PS) is frequently applied in some patients with terminal illness, who are near the end of life, to ameliorate unendurable and refractory distress; it is considered an effective treatment modality for the management of refractory symptoms when aggressive efforts do not provide relief. PS consists of the use of medications that induce sedation and decrease the level of consciousness with the aim of relieving intolerable suffering in the last days of life. The most frequent physical refractory symptoms are pain, delirium, and dyspnea, but PS is also indicated to treat existential suffering or psychological distress, which is an extremely difficult and delicate problem. PS has been widely debated given its obvious ethical, sociocultural, and decision-making implications. It has been reported that PS is given to 2-52% of patients with terminal illness; studies have suggested that PS is successful in managing intractable symptoms at the end of life, satisfactory for family members, and does not have detrimental effects on survival.

Spinal cord stimulation in the management of neuropathic pain in cancer patients: case report / Neuroestimulación medular en el manejo del dolor neuropàtico en pacientes con cáncer: reporte de caso

Abstract Introduction Neuropathic pain is present in up to 40 % of all cancer patients. A considerable number of patients fail to achieve enough pain relief with conventional treatment, which is why therapeutic alternatives such as spinal cord stimulation should be considered. Case description and results This is the case of a female patient with chronic neuropathic pain secondary to a partial femoral nerve injury sustained during resection and lymph node dissection surgery with curative intent for a large stage II cell squamous cell carcinoma T2N0M0, localized in the right popliteal fossa. The patient presented with difficult to manage chronic neuropathic pain, despite receiving multiple oral analgesics and nerve blocks. A medullary neurostimulator was implanted that relieved the patient's pain intensity in up to 80%, in addition to improved function and quality of life. Conclusions Spinal cord stimulation is considered an effective neuromodulatory intervention which has shown satisfactory results in the treatment of various types of refractory chronic pain in cancer patients, including neuropathic pain.

Resumen Introducción El dolor neuropático está presente hasta en el 40 % de los pacientes con cáncer. Un número considerable de pacientes no logran un alivio suficiente del dolor con el tratamiento convencional, por lo cual deben considerarse alternativas terapéuticas como la estimulación de la médula espinal. Descripción del caso y resultados Caso de una paciente con dolor neuropático crónico secundario a lesión parcial de nervio femoral durante cirugía de resección y vaciamiento ganglionar con objetivos curativos de carcinoma escamocelular de célula grande T2N0M0 estadio II, localizado en la fosa poplítea derecha, quien cursó con dolor neuropático crónico de difícil manejo a pesar de recibir múltiples analgésicos orales y bloqueos nerviosos. Se implantó un neuroestimulador medular con lo cual se logró un alivio hasta del 80 % en intensidad de dolor de la paciente, además de una mejoría de su funcionalidad y calidad de vida. Conclusiones La estimulación de la médula espinal se considera una intervención neuromoduladora eficaz, que ha demostrado resultados satisfactorios para tratar diversas formas de dolor crónico refractario en los pacientes con cáncer, incluido el dolor neuropático.
