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.

Cervical Cordotomy in Terminal Cancer: Pain Relieving in Oncological Treatment

Cordotomy consists in the discontinuation of the lateral spinothalamic tract (LST) in the anterolateral quadrant of the spinal cord, which aims to reduce the transference of nociceptive information in the dorsal horn of the gray matter of the spinal cord to the somatosensory cortex. The main indication is for patients with terminal cancer that have a low life expectancy. It improves the quality of life by relieving pain. The results are promising and the pain relief rate varies between 69 and 100%. Generally speaking, the complications are mostly temporary and not remarkable.

Calidad de vida y balance sagital en la evolución de los pacientes con mieloma múltiple tratados con vertebroplastia percutánea / Quality of Life and Sagittal Balance in the Evolution of Patients with Multiple Myeloma Who Received Treatment

RESUMEN Introducción: El mieloma múltiple representa el 1 por ciento de las neoplasias y el 10 por ciento de las hemopatías malignas. La edad media de presentación es 65 años. El dolor óseo en columna vertebral y costillas constituye su manifestación inicial. El tratamiento quirúrgico del mieloma múltiple en la columna consiste en descompresión amplia y artrodesis. La vertebroplastia se considera técnica de elección porque restablece el balance sagital y coronal, contribuye al fortalecimiento del cuerpo vertebral, y disminuye el dolor asociado a fracturas. Objetivo: Evaluar el efecto de la vertebroplastia sobre la calidad de vida y el balance sagital, en la disminución del dolor. Métodos: Se estudiaron 192 pacientes con mieloma múltiple con fractura en la columna, 80 tratados con vertebroplastia y 112 en forma conservadora. Se utilizó el cuestionario de Oswestry y la escala de Karnosfky. Resultados: La vertebroplastia disminuyó 0,52 veces el uso de analgésicos opioides. Conclusiones: La vertebroplastia representa un mayor beneficio de la calidad de vida de los pacientes aquejados de mieloma múltiple con fractura vertebral; repercute en el mejoramiento del balance sagital, el nivel de discapacidad y la capacidad para realizar tareas cotidianas(AU)

ABSTRACT Introduction: Multiple myeloma accounts for 1 percent of neoplasms and for 10 percent of malignant hematomas. The mean onset age is 65 years. Bone pain in the spine and ribs is its initial manifestation. Surgical treatment for multiple myeloma in the spine consists in wide decompression and arthrodesis. Vertebroplasty is considered the choice technique because it restores sagittal and coronal balance, contributes to the strengthening of the vertebral body, and reduces pain associated with fractures. Objective: To assess the effect of vertebroplasty on quality of life and the effect of sagittal balance in reducing pain. Methods: 192 patients with multiple myeloma and spinal fracture were studied, 80 treated with vertebroplasty and 112 treated conservatively. The Oswestry questionnaire and the Karnofsky scale were used. Results: Vertebroplasty decreased the use of opioid analgesics by 0.52 times. Conclusions: Vertebroplasty represents a greater benefit for the quality of life of patients suffering from multiple myeloma with vertebral fracture. It affects the improvement of sagittal balance, the level of disability, and the ability to perform daily tasks(AU)
