SUMMARY

Whole-breast irradiation, as part of breast-conservation therapy (BCT), has been well-established the last decades. Nonetheless, most local recurrences found after BCT are within or close to the tumour bed. This led to the concept of partial breast irradiation (PBI), delivering the radiation dose to a decreased target volume, thereby lowering exposure to the organs at risk and hence potentially minimizing late adverse effects. This became increasingly important with growing survivorship of patients with early-stage breast cancer over the past decades and the consideration of late adverse effects is gaining more importance. In this review, we will present an overview of the current literature, techniques to deliver PBI and we try to establish whether there is a place for PBI in early-stage breast cancer treatment.

Summary

A 54-year old man presented with a new-onset headache, phonophobia, tinnitus, blurred vision, and nausea. Further imaging and histological examination confirmed the diagnosis of an olfactory neuroblastoma. Olfactory neuroblastoma or esthesioneuroblastoma is a rare type of cancer, originating from the basal stem cells of the olfactory epithelium in the nasal cavity. The patient received a maximal possible surgical resection of the tumour, followed by adjuvant chemo-irradiation. Given the absence of neck metastases, no prophylactic treatment of the neck was done. Recent studies state that standard treatment of esthe-sioneuroblastoma consists of surgical resection, followed by local radiotherapy. Adjuvant chemotherapy is recommended for the locally advanced tumours. As for the treatment of the neck, current consensus is to perform salvage therapy when neck metastases are present.
