RESUMO
Antineoplastic therapies for prostate cancer (PCa) have traditionally centered around the androgen receptor (AR) pathway, which has demonstrated a significant role in oncogenesis. Nevertheless, it is becoming progressively apparent that therapeutic strategies must diversify their focus due to the emergence of resistance mechanisms that the tumor employs when subjected to monomolecular treatments. This review illustrates how the dysregulation of the lipid metabolic pathway constitutes a survival strategy adopted by tumors to evade eradication efforts. Integrating this aspect into oncological management could prove valuable in combating PCa.

Background: In Cystic Pneumatosis Intestinalis, intramural gas filled cysts are formed in the gastrointestinal wall. Its pathogenesis is unknown and its clinical manifestations are variable. Case report: We report a 33 years old HIV positive woman in retroviral treatment presenting with abdominal pain and signs of peritoneal irritation. An abdominal CT scan showed intra and retroperitoneal gas and pneumatosis intestinalis in the right and transverse colon. The patient was managed conservatively with nasogastric aspiration with a favorable evolution and was discharged ten days after admission.
Introducción: Se denomina neumatosis quística intestinal (NQI) a la formación de quistes intramurales rellenos de gas ubicados en la pared del sistema gastrointestinal, de patogénesis desconocida y de manifestaciones clínicas muy variables. Caso clínico: Presentamos un caso de neumoperitoneo masivo por NQI intestinal en una paciente VIH+ que acude a urgencias por dolor y distensión abdominal y que, a pesar de las espectaculares imágenes de la radiografía simple de abdomen y la tomografía computarizada (TC), se trató conservadoramente. Este caso pone de manifiesto el reto diagnóstico y la duda que supone para el cirujano acostumbrado a "operar para curar", no operar un cuadro que hasta hace poco tiempo inexcusablemente suponía una laparotomía exploradora.
