RESUMEN
BACKGROUND: The U grading of Ultrasound scan (USS) is used to assess the likelihood of malignancy in a thyroid nodule and help determine those that warrant an FNAC confirmation. All those of a U3-5 warrant an FNAC for confirmation and typing. This study aims to review the follow-up practice and the likelihood of picking up a malignancy on subsequent USS and FNAC, for those determined as an indeterminate U3 nodule. METHODS: We retrospective reviewed the trust database (Portal) for patients who had a U3 nodule reported on USS identified, and clinical, operative and outcomes data were analysed. RESULTS: 258 scans were identified over a 5-year period. The average age was 59 (range 15- 95) years old at first USS with a female to the male sex ratio of 4:1. The average number of USS that each patient prior to final diagnosis had averaged at 2.8 (range 1-12). Of those with an initial Thy status, 64 (33%) were benign (Thy2) and a further 49 (25%) were non diagnostics (Thy1). Over time, only 7 nodules were upgraded to a potential malignancy. Of those who underwent surgery, a final histological diagnosis was obtained in 41 cases. Only Thy1, 2 and 3f produced benign final histology results. CONCLUSIONS: For those indeterminate (U3) nodules of Th1-3f, electing for a watch and wait management strategy is reasonable for up to 2.5 years and 4 follow-up scans at an interval of 6-12 months should be implemented. A Thy2 result on a U3 nodule should not be taken as completely reassuring, a high index of suspicion of malignancy must be maintained.

BACKGROUND: Fine-needle aspiration cytology (FNAC) is an integral part of thyroid nodule assessment. Nodules with an indeterminate cytology (THY3a-f) require formal histological assessment to confirm benign or malignant pathology. This study aimed to provide data for an evidence-based approach for management of patients with THY3f nodules. METHODS: Retrospective review of patients who had a thyroid FNAC reported as suspicious of follicular neoplasm (THY3f) or showing atypia (THY3a) were identified, and clinical, operative and outcomes data were analysed. RESULTS: Between 2018 and 2020, 200 patients (167F:33M, median age 51 years (range:18-86 years)) had a THY3f cytology. Most presented with a palpable nodule (n=104; 68.4%). Overall, 152 (76.0%;130F:23M) underwent surgery and 31 (20.4%) were found to have a thyroid carcinoma (22 follicular carcinomas, 7 papillary carcinomas, 1 medullary thyroid carcinoma and 1 metastatic renal carcinoma). An additional incidental carcinoma (size: 0.7-13mm) was found in seven (4.6%). Among those with cancer, a completion thyroidectomy and radioactive iodine treatment was indicated in nine (<6% of the entire cohort). Previously suggested risk factors for malignancy, eg male gender, large tumour size (>4cm) or age, were not found to be associated with increased risk. During the same period, THY3a cytology was reported in 53 patients, of whom 29 underwent diagnostic surgery and 4 patients were found to have a thyroid cancer (follicular, n=3 and medullary, n=1). CONCLUSION: One in five patients with features suspicious of a follicular neoplasm (THY3f) has a thyroid carcinoma. This risk is much lower for THY3a. This study reinforces the current recommendation for thyroid surgery in all patients with a reliable THY3f cytology, as no further stratifying risk factors could be identified.

Background: Benign prostatic hyperplasia (BPH) is a common pathology in elderly patients, inducing lower urinary tract symptoms. The treatment of BPH is first a medical option, then a surgical treatment, either by endoscopy or open surgery. We here report a case of GreenLight HPS™ laser photovaporization (PV) with an impaired maintenance of median lobe postoperatively, unimportant on functional results. Case Presentation: A 68-year-old man presented with lower urinary tract symptoms in the last 2 years, treated first by medicine with good response. On digital rectal examination, the enlarged prostate was homogeneous and regular. International Prostate Symptom Score (IPSS) was 30/35, Incontinence Quality of Life (iQol) 6/6, and International Index of Erectile Function 5 14/25 with regular sexual activity. Transrectal ultrasound (TRUS) reported BPH of 62 g with a median lobe of 6 g protruding into the bladder. At uroflowmetry, maximum urinary flow rate (Qmax) was 8 mL/s for 90 cc void volume and 20 cc postvoid residual. After failure of medical treatment, we offered a surgical treatment option by laser therapy using the 180W XPS GreenLight™. At 1-month follow-up, functional outcomes were improved with a Qmax of 11 mL/s, postvoiding residual volume 0 cc, IPSS 12/35, and iQol 2/6. At 3-month follow-up, outcomes still improved, although the TRUS reported a prostate volume of 30 g with a persistent median lobe. Conclusion: Impaired maintenance of median lobe after GreenLight laser PV does not seem to affect functional results. This case report opens the way for a new therapeutic strategy for patients according to their prostate anatomy. A randomized clinical trial could be done about surgical treatment for patient BPH according to prostate volume and anatomy.
