An innovative multimodality approach for sentinel node mapping and biopsy in head and neck malignancies.
Recent innovations such as preoperative SPECT/CT, intraoperative imaging using portable devices and a hybrid tracer were evaluated in a multimodality approach for sentinel node (SN) mapping and biopsy in head and neck malignancies. ⋯ In the present series 26% additional SNs were found using the multimodal approach, that incorporates SPECT/CT and intraoperative imaging to the conventional procedure. This approach appears to be useful in malignancies located close to the area of lymphatic drainage such as the periauricular area and the oral cavity.

Standardized uptake value and metabolic tumor volume measured by ¹⁸F FDG PET/CT are sensitive biomarkers for the presence of lymph node metastasis in patients with cervical carcinoma.
The aim of this study was to evaluate whether tumor standardized uptake value (SUVmax) and metabolic tumor volume (MTV) associate with the presence of PET-positive pelvic/para-aortic lymph nodes (LN) in cervical cancer patients. ⋯ Presence of PET-positive LN correlates with tumor SUVmax and MTV of cervical tumor. These findings support the use of PET/CT in the pretreatment evaluation of cervical cancer patients in order to identify cases with high risk of lymphatic involvement.
