[Evaluation of efficacy and clinical impact of 18F-FDG-PET in the diagnosis of recurrent medullary thyroid cancer with increased calcitonin and negative imaging test].
To evaluate the efficacy and clinical impact of the FDG-PET in the diagnosis of suspicion of recurrence of medullary thyroid cancer (MTC) in patients with elevated serum calcitonin and negative imaging test. ⋯ In patients with MTC and suspected recurrence with elevated calcitonin and negative imaging test, the FDG is the best test for the diagnosis of occult recurrence in MTC with elevated calcitonin and negative imaging techniques with elevated clinical impact. It facilitates the therapeutic management of the patients with MTC recurrence, and should be included in the diagnosis algorithm in these patients.

[Incidence of axillary recurrence after a negative sentinel lymph node result in early stages of breast cancer: a 5-year follow-up].
The sentinel lymph node (SLN) biopsy is currently the procedure of choice for axillary node staging in initial stages of breast cancer. The purpose of this study is to establish our false negative rate within a 5-year follow-up period in 258 patients with breast cancer staged with this procedure. ⋯ The risk of developing axillary recurrence after a negative SLN without axillary node dissection is low enough to consider the SLN procedure to be the best approach for axilla staging in early breast cancer. This staging technique also makes it possible to achieve local disease control without diminishing the survival of the patients.
