ABSTRACT

Aim of Study: To assess the effect of strictly local treatment [intraarterial chemotherapy (iaCHT) with high-dose cisplatin and parallel neutralization] in the primary oral and oropharyngeal cancer (OOSCC) on the dependent cervical lymph nodes. Patients and Methods: Seventeen consecutive patients with OOSCC and clinically positive necks underwent a prospective blinded comparison of two pre-surgical fluor18-deoxyglucose (FDG)-positron emission tomography (PET) examinations: baseline examination 1 week before and follow-up examination 3 weeks after iaCHT. Maximal standardized uptake (SUVmax) values of lymph nodes were measured and compared with each other and histopathology. Results: The SUVmax value of the primary and all neck lymph nodes with uptake decreased significantly. Twelve/17 patients having metastases revealed significant decrease (P = 0.03), and benign lymph nodes showed non-significant decrease of the SUVmax. All neck lymph nodes with uptake and nodal metastases showed a significant reduction (P = 0.004) of standard uptake values (SUV). Conclusion: A regional effect of intraarterial cisplatin is proven. To date, it is not clear whether this is due to decreasing inflammatory reaction or a translymphatic anti-neoplastic effect.

ABSTRACT

Los autores destacan los progresos realizados en los últimos años en la exploración del hígado y de las vías biliares haciendo especial hincapié en la colangiografía retrógrada. Se precisan sus indicaciones y sus ventajas entre las cuales se señalan exploración endoscópica de estómago, duodeno y papila; visualización de vías biliares y pancreáticas; posibilidad de papilotomía y tratamiento de litiasis, (disolución, extracción y litotripsia) y de estenosis benignas y malignas del colédoco. Se mencionan las limitaciones y riesgos del procedimiento que tiene muy baja mortalidad (0,9%) y mortalidad (0,09%)
