Clinical importance of retropharyngeal lymph node metastases

Abstract

Összefoglaló. A retropharyngealis nyirokcsomóáttétek incidenciája a primer fej-nyaki daganat lokalizációjától függ. Leggyakrabban az előrehaladott vagy recidív nasopharynx-carcinomák esetén fordul elő, de III-IV. stádiumú oro- és hypopharynxtumorok esetén is megjelenhetnek. Non-nasopharyngealis primer tumoroknál a manifesztációjuk kedvezőtlen prognosztikai faktornak tekinthető, melynek hátterében a diagnosztikus nehézség miatti késői detektálás, a kifejezetten nehéz sebészi eltávolíthatóság, valamint az agresszív biológiai viselkedés állhat. Az esetismertetésünkben bemutatásra kerülő, 58 éves betegünknél bal oldali elülső szájfenéki primer tumort diagnosztizáltunk azonos oldali nyaki és retropharyngealis nyirokcsomó-metastasissal, mely a nemzetközi irodalom alapján extrém raritás, incidenciája kevesebb mint 1%. A retropharyngealis nyirokcsomók diagnosztikájában a lokalizáció miatt a képalkotóknak jut hangsúlyosabb szerep. Elhelyezkedésük nemcsak diagnosztikus, hanem sebésztechnikai kihívást is jelentenek az életfontosságú anatómiai képletek közelsége, illetve a szűk feltárási viszonyok miatt. Ilyenformán ezek a műtétek csak intenzív osztályos háttérrel és kellő jártassággal rendelkező centrumokban végezhetők. Az alapvetően rossz prognózist a korai diagnózis és a multimodális terápia kedvezően befolyásolja. Esetünkben a komplex kezeléssel (sebészi terápia és posztoperatív radiokemoterápia) sikerült lokoregionális tumormentességet elérni, és ezzel a teljes és a betegségmentes túlélési időt növelni.

Involved nodes are seen most commonly in cases of advanced or recurrent nasopharyngeal carcinoma, however, they might occur with stage III-IV oro- and hypopharyngeal tumours. The involvement of retropharyngeal lymph nodes has been associated with poor outcome of non-nasopharyngeal primary tumours, which might be explained by the delayed diagnosis, the difficult surgical procedure in the retropharyngeal space, and the aggressive nature of the disease. Here we present the case of a 58-year-old patient with an anterior oral cavity tumour on the left side with ipsilateral cervical lymph node and retropharyngeal lymph node metastases, which has been noted an extreme rarity in the literature with less than 1% incidence. Due to the localization of the retropharyngeal lymph nodes, the detection is based on imaging modalities. It represents a challenge for diagnosis and surgical treatment due to the close proximity of vital anatomical structures. Accordingly, these operations should only be performed in specialist surgical centres with intensive care units. The early diagnosis and the multimodality treatment might have a positive effect on the poor prognosis. In our case, we managed to achieve locoregional disease-free status with the complex treatment (surgical therapy and postoperative radiochemotherapy) and increase the overall and the disease-free survival.
