- Abstract : Background: Ductal carcinoma in situ (DCIS) in the breast that is diagnosed by biopsy implies a risk of upstaging to invasive carcinoma (IC) on final pathology. These patients require a sentinel lymph node biopsy (SLNB) for axillary staging. A two‐stage procedure is not always feasible and precise selection of patients who should be offered SLNB is crucial. The aims were: to determine the rate of upstaging, and use of redundant and required SLNB in women with a preoperative diagnosis of DCIS; and to identify patient and tumour characteristics that increase the risk of upstaging. Methods: Patients with DCIS treated between 2008 and 2016 were identified using Orbit operation planning system software, and those suitable for the study were selected based on review of the medical records. Upstaging rates and proportions of redundant and required SLNBs were calculated. Associations between clinicopathological characteristics and upstaging were analysed using univariable and multivariable logistic regression analyses. Results: Of 1368 patients initially identified, 975 women with a preoperative diagnosis of DCIS were included in the study. Tumours in 246 of these patients (25·2 per cent) were upstaged to IC. Redundant SLNB was performed in 392 of 975 women (40·2 per cent). Forty‐four patients (4·5 per cent) with a final diagnosis of IC were not offered SLNB and thus potentially undertreated. In adjusted analysis, DCIS size, palpability and mass formation identified byAbstract : Background: Ductal carcinoma in situ (DCIS) in the breast that is diagnosed by biopsy implies a risk of upstaging to invasive carcinoma (IC) on final pathology.

Redundant SLNB was performed in 392 of 975 women (40·2 per cent). Forty‐four patients (4·5 per cent) with a final diagnosis of IC were not offered SLNB and thus potentially undertreated. In adjusted analysis, DCIS size, palpability and mass formation identified by breast imaging were associated with increased risk of upstaging. The Van Nuys classification was not associated with upstaging. Conclusion: Most patients with IC on final pathology underwent SLNB, but a considerable number of patients with DCIS had a redundant SLNB. Lesion size, palpability and mass formation, but not Van Nuys classification group, are suggested risk factors for upstaging. Abstract : As patients with ductal carcinoma in situ (DCIS) are at risk of tumour upstaging to invasive carcinoma (IC) after surgery, careful selection of patients benefiting from sentinel lymph node biopsy (SLNB) is crucial as this may aid in preventing redundant SLNBs. Clinical features of the patient can aid the selection of patients for SLNB.

Estas pacientes requieren una biopsia del ganglio linfático centinela ( sentinel lymph node biopsy, SLNB) para la estadificación axilar. Dado que un procedimiento en dos etapas no siempre es factible, la selección precisa de pacientes a las que se debe ofrecer SLNB es crucial. El objetivo del estudio era determinar la tasa de infraestadiaje inicial y el uso repetido/requerido de SLNB en mujeres con un diagnóstico preoperatorio de CDIS. Además, se identificarán las características del paciente y del tumor que aumentan el riesgo de necesidad de re‐estadificación. Métodos: Un total de 1.368 mujeres con DCIS tratadas entre 2008‐2016 fueron identificadas utilizando el programa informático de la planificación de las intervenciones hospitalarias. Después de la revisión de los registros médicos, se incluyeron 975 pacientes en la cohorte del estudio. Se calcularon las tasas de infraestadiaje y la proporción del uso repetido/requerido de SLNB. Las asociaciones entre las características clinicopatológicas y la necesidad de re‐estadificación se analizaron mediante análisis de regresión logística univariable y multivariable. Resultados: De 975 pacientes diagnosticados inicialmente de DCIS, 246 (25, 2%) fueron re‐estadiados a IC. Se realizó SLNB repetidas en 392 (40, 2%) de estos pacientes. En 44 pacientes (4, 5%) con un diagnóstico final de IC no se les ofreció la SLNB y, por lo tanto, pudieron estar potencialmente infratratados. En el análisis ajustado, el tamaño del DCIS, la palpabilidad y la presencia de una masa en las imágenes radiológicas de la mama se asociaron con un mayor riesgo de necesidad de re‐estadificación por infraestadiaje inicial. La clasificación de Van Nuys no se asoció con la re‐estadificación. Conclusión: La mayoría de pacientes con IC en la patología final se sometieron a SLNB, sin embargo, un número considerable de pacientes con DCIS se sometieron a SLNB repetidas. El tamaño de la lesión, la palpabilidad y la presencia de masa, aunque no el grupo de clasificación de Van Nuys, se consideran factores de riesgo relacionados con infraestadiaje inicial y necesidad de re‐estadificación final. … (more)
