Feasibility of lymphoscintigraphy for sentinel node identification after neo-adjuvant therapy

Ann Ital Chir. 2017:88:201-205.

Abstract

Aim: To assess the sentinel-node identification rate at lymphoscintigraphy and its technical feasibility after neo-adjuvant treatments.

Material of study: Between 2000 and 2013, 444 consecutive patients affected by primary locally advanced breast cancer were enrolled in this study. All individuals were candidate for neo-adjuvant treatments and for lymphoscintigraphy before surgery.

Results: The median age was 44 years at onset; almost one sentinel node was identified during lymphoscintigraphy in 430 cases. The detection rate at lymphoscintigraphy was 96.9% (95% CI, 94.8-98.1%). Considering the correlation between specific treatments and sentinel node identification rate, we verified that the detection rate did not vary significantly (p=0.53) according to the type of neo-adjuvant therapies administered to the patients.

Conclusions: Our results demonstrated that lymphoscintigraphy for sentinel node identification is a safe and feasible procedure after neo-adjuvant therapies, independently of treatment types.

Key words: Breast Cancer, Neo-Adjuvant Treatment, Sentinel lymphnode biopsy, Lymphoscintigraphy.

Lo scopo dello studio è quello di valutare la fattibilità della linfoscintigrafia dopo trattamento neoadiuvante nelle pazienti affette da carcinoma mammario localmente avanzato. Sono state selezionate 444 pazienti dal 2000 al 2013 con neoplasia mammaria e candidate al trattamento neoadiuvante e alla linfoscintigrafia prima dell’intervento chirurgico. L’età media era di 44 anni alla diagnosi. In 430 casi almeno un linfonodo sentinella era stato identificato alla linfoscintigrafia. L’identification rate complessivo era del 96.9% (95% CI, 94.8-98.1%). Non abbiamo notato una correlazione statistica tra l’identification rate e il tipo di trattamento neoadiuvante eseguito (p=0.53). I nostri risultati hanno dimostrato che la linfoscintigrafia per l’identificazione del linfonodo sentinella è una procedura fattibile dopo trattamento neoadiuvante, indipendentemente dal tipo di farmaco utilizzato.
