BACKGROUND: Sentinel node (SN) has been proved to be a reliable technique in predicting the lymph nodes state of the axilla in breast cancer. For the majority of the authors the intradermal and peritumoral injection is the best way. PATIENTS AND METHODS: Our experience, from 1997, includes 587 cases of SN in women with resectable breast cancer less than 3 cm of diameter. We performed the lymphoscintigraphy after a peritumoral injection of radioactive tracer and, if the lesion was superficial, we associated an intradermal injection on the skin above the lesion itself. Two patients had multifocal right breast cancer. We did two separate injections around each tumor. RESULTS: The radioactive tracer spread towards the internal mammary chain and homolateral axillary nodes. CONCLUSIONS: We consider the peritumoral injection as essential in tumors located deeply in the breast (under ultrasound guide if not palpable) together with intradermal injection in superficial ones. Using this technique the possibility of a mis-identification of the SN is reduced.

Abstract
BACKGROUND: Sentinel node (SN) has been proved to be a reliable technique in predicting the lymph nodes state of the axilla in breast cancer. For the majority of the authors the intradermal and peritumoral injection is the best way. PATIENTS AND METHODS: Our experience, from 1997, includes 587 cases of SN in women with resectable breast cancer less than 3 cm of diameter. We performed the lymphoscintigraphy after a peritumoral injection of radioactive tracer and, if the lesion was superficial, we associated an intradermal injection on the skin above the lesion itself. Two patients had multifocal right breast cancer. We did two separate injections around each tumor. RESULTS: The radioactive tracer spread towards the internal mammary chain and homolateral axillary nodes. CONCLUSIONS: We consider the peritumoral injection as essential in tumors located deeply in the breast (under ultrasound guide if not palpable) together with intradermal injection in superficial ones. Using this technique the possibility of a mis-identification of the SN is reduced.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
