Introduction: In recent years, cultural changes in today's society and improved risk assessment have increased the indication for mastectomies in women with breast cancer. Various studies have confirmed the oncological safety of sparing mastectomies and immediate reconstruction. The objective of this study is to analyze the incidence of locoregional relapses of this procedure and its impact on reconstruction and overall survival., Patients and Methods: Prospective study of patients with breast carcinoma who underwent a sparing mastectomy and immediate reconstruction. Locoregional relapses and their treatment and their impact on survival were analyzed., Results: The study group is made up of 271 women with breast carcinoma treated with a skin-sparing mastectomy and immediate reconstruction. The mean follow-up was 7.98 years and during the same 18 locoregional relapses (6.6%) were diagnosed: 72.2% in the mastectomy flap and 27.8% lymph node. There were no significant differences in the pathological characteristics of the primary tumor between patients with and without locoregional relapse, although the percentage of women with hormone-sensitive tumors was higher in the group without relapse. Patients with lymph node relapse had larger tumors (80% T2-T3) and 60% had axillary metastases at diagnosis, compared to 7.7% of women with skin relapse (p = 0.047). All patients operated on for locoregional relapse preserved their reconstruction. The incidence of metastases and deaths was significantly higher in patients with a relapse, causing a non-significant decrease in overall survival., Conclusion: Locoregional relapses are a rare event in women with a sparing mastectomy and immediate reconstruction. Most patients with locoregional relapse can preserve their initial reconstruction through local resection of the tumor and adjuvant and / or neoadjuvant therapies., (Copyright © 2022 AEC.

We report the cases of 6 patients, all younger than 14 years of age, with differentiated thyroid carcinoma. None of the patients had a previous history of radiation exposure. All patients presented with an enlarged thyroid gland as a solitary nodule, with or without cervical nodes. The fine-needle aspiration cytological examination was found to be the most sensitive and specific, evidencing 5 pure papillary adenocarcinoma and 1 follicular. Our standard preoperative evaluation included thyroid scintiscan and ultrasound examination, laboratory studies of thyroid function and serum calcitonin, chest x-ray, fine needle aspiration and vocal cord examination. The treatment was total thyroidectomy and bilateral modified neck dissection. A whole body scan (WBS) with 131I was performed 6 weeks after surgery, followed by radioiodine therapy for ablation of thyroid remnants and treatment of metastases when present. Patients then began thyroid replacement treatment. The follow-up of the patients consisted of thyroglobulin and WBS. The microscopic carcinoma was found in the contralateral lobe in 100%. Lung metastases were detected in 2 patients. All of the patients have survived during a follow-up period ranging from 6 to 108 months.
