Radioguided surgery with iodine-125 seeds in breast cancer patients treated with neoadjuvant chemotherapy.
To evaluate the use of radioactive iodine-125 seed (RIS) in breast and/or axillary surgery, in patients with breast cancer treated with neoadjuvant chemotherapy (NAC). ⋯ RIS allow to perform breast-conserving surgery and improve detection of residual axillary disease in patients treated with NAC.

[Diagnosis of COVID-19 pneumonia in asymptomatic patients after an oncological PET/CT].
On January 30, 2020, the World Health Organization (WHO) declared an international emergency due to the pandemic caused by a new coronavirus. There are some oncological indications that have special priority and studies are still being carried out despite the current situation. In these studies we have found suspicious findings of COVID-19 pneumonia in asymptomatic patients. The objective of this work is to assess the incidence of these findings, describe their characteristics and the evolution of suspected patients. ⋯ Patients with COVID-19 can present few symptoms of the disease, and in PET/CT studies both presymptomatic and almost asymptomatic patients can be detected, so nuclear medicine physicians should take special attention to the pulmonary evaluation of PET/CT studies.

Functional image in soft tissue sarcomas: An update of the indications of 18F-FDG-PET/CT.
Soft tissue sarcomas (STS) are a rare and heterogeneous group of tumors. They account for 1% of solid malignant tumors in adults and 7% in children and are responsible for 2% of cancer mortality. ⋯ The general recommendations for the use of PET/CT in STS at present are summarized as the initial evaluation of soft tissue tumours when conventional image does not establish benignity with certainty and this determines the approach; in biopsy guiding in selected cases; in the initial staging, as additional tool, for rhabdomyosarcoma and STS of extremities or superficial trunk and head and neck tumours; in the suspicion of local recurrence when the CT or MRI are inconclusive and in the presence of osteosynthesis or prosthetic material and in assessment of therapy response to local/systemic therapy in stages ii/iii. In addition, PET/CT has the added value of being a surrogate marker of the histopathological response and it provides prognostic information, both in the baseline study and after treatment.

Combined procedure of marking axillary positive node with iodine-125 seed and sentinel lymph node biopsy in breast cancer patients treated with neoadjuvant chemotherapy.
To present our initial experience in the combined procedure of intraoperative detection of axillary positive node marked with 125I seed (ML) and sentinel node biopsy (SLN) after neoadjuvant chemotherapy (NACT), in breast cancer patients. ⋯ Placing of 125I seeds is a feasible technique for intraoperative location of axillary positive node combined with SLN. The histopathological result of ML allows the axillary status to be determined after neoadjuvant chemotherapy.
