Neoadjuvant Therapy with Multikinase Inhibitors for Locally Advanced Differentiated Thyroid Cancer: A Systematic Review. Thyroid : official journal of the American Thyroid Association, 35(10), 1108-1119.More infoThe use of multikinase inhibitors (MKIs) in thyroid cancer has been established to downsize and facilitate resection of poorly differentiated, differentiated high-grade, anaplastic, and medullary thyroid cancer. Case reports and case series have suggested the potential use of MKIs as neoadjuvant therapies for locally advanced differentiated thyroid cancer (DTC). Our objective was to review available studies and assess if neoadjuvant therapy with MKI can improve surgical and oncological outcomes in patients with locally advanced DTC. A systematic search of four different databases (PubMed, Cochrane Library, Scopus, and EMBASE) with no time restrictions was performed to identify relevant observational studies evaluating patients with locally advanced DTC who received neoadjuvant therapy before surgery with MKI (PROSPERO ID: CRD420251012812). A total of 119 participants from 23 observational studies (12 case reports, 9 case series, and 2 prospective phase II studies) were included. Lenvatinib was the most frequently used MKI, followed by sorafenib. Tumor volume reduction ranged from 25% to 87%, and partial response rates ranged between 33.3% and 76.9%, whereas progressive disease was described only in seven cases. Of 114 patients with inoperable or potentially resectable tumors with associated high perioperative morbidity, 95 (83.3%) were able to undergo surgery. Neoadjuvant MKIs in locally advanced DTC may improve resection rates. The overall low quality of evidence prompts further prospective studies to confirm these findings.

Molecular Variants and Their Risks for Malignancy in Cytologically Indeterminate Thyroid Nodules. Thyroid : official journal of the American Thyroid Association, 29(11), 1594-1605.More infoGene panels are routinely used to assess predisposition to hereditary cancers by simultaneously testing multiple susceptibility genes and/or variants. More recently, genetic panels have been implemented as part of solid tumor malignancy testing assessing somatic alterations. One example is targeted variant panels for thyroid nodules that are not conclusively malignant or benign upon fine-needle aspiration (FNA). We systematically reviewed published studies from 2009 to 2018 that contained genetic data from preoperative FNA specimens on cytologically indeterminate thyroid nodules (ITNs) that subsequently underwent surgical resection. Pooled prevalence estimates per gene and variant, along with their respective positive predictive values (PPVs) for malignancy, were calculated. Our systematic search identified 540 studies that were supplemented by 18 studies from bibliographies or personal files. Sixty-one studies met all inclusion criteria and included >4600 ITNs. Overall, 26% of nodules contained at least 1 variant or fusion. However, half of them did not include details on the specific gene, variant, and/or complete fusion pair reported for inclusion toward PPV calculations. The PPVs of genomic alterations reported at least 10 times were limited to (98%, 95% confidence interval [CI 96-99%]), (55% [CI 34-78%]), (45% [CI 22-72%]), (42% [CI 19-68%]), and (38% [CI 23-55%]). Excluding , the pooled PPV for all other specified variants and fusions was 47%. Multiple variants within the same nodule were identified in ∼1% of ITN and carried a cumulative PPV of 77%. The chance that a genomic alteration predicts malignancy depends on the individual variant or fusion detected. Only five alterations were reported at least 10 times; had a PPV of 98%, while the remaining four had individual PPVs ranging from 38% to 55%. The small sample size of most variants and fusion pairs found among ITNs, however, limits confidence in their individual PPV point estimates. Better specific reporting of genomic alterations with cytological category, histological subtype, and cancer staging would facilitate better understanding of cancer prediction, and the independent contribution of the genomic profile to prognosis.

Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 36(18), 1831-1839.More infoPurpose To investigate the risk and outcomes of second hematologic malignancies (SHMs) in a population-based cohort of patients with well-differentiated thyroid cancer (WDTC) treated or not with radioactive iodine (RAI). Methods Patients with WDTC were identified from SEER registries. Competing risk regression analysis was performed to calculate the risks of SHMs that occurred after WDTC treatment and outcomes after SHM development were assessed. Results Of 148,215 patients with WDTC, 53% received surgery alone and 47% received RAI. In total, 783 patients developed an SHM after a median interval of 6.5 years (interquartile range, 3.3 to 11.2 years) from WDTC diagnosis. In multivariable analysis, compared with those undergoing thyroidectomy alone, RAI treatment was associated with an increased early risk of developing acute myeloid leukemia (AML; hazard ratio, 1.79; 95% CI, 1.13 to 2.82; P = .01) and chronic myeloid leukemia (CML; hazard ratio, 3.44; 95% CI, 1.87 to 6.36; P < .001). This increased risk of AML and CML after RAI treatment was seen even in low-risk and intermediate-risk WDTC tumors. Occurrence of AML but not CML in patients with WDTC was associated with shorter median overall survival compared with matched controls (8.0 years v 31.0 years; P = .001). In addition, AML developing after RAI trended toward inferior survival compared with matched controls with de novo AML (median overall survival, 1.2 years v 2.9 years; P = .06). Conclusion Patients with WDTC treated with RAI had an increased early risk of developing AML and CML but no other hematologic malignancies. AML that arises after RAI treatment has a poor prognosis. RAI use in patients with WDTC should be limited to patients with high-risk disease features, and patients with WDTC treated with adjuvant RAI should be monitored for myeloid malignancies as part of cancer surveillance.

Pituitary, 16(3), 351-3.More infoLiterature on hyperprolactinemia in the setting of a nipple piercing is limited to individuals with concomitant breast/chest wall infection. It is unclear if chronic nipple stimulation from a piercing alone can cause sustained elevations of serum prolactin. Nipple piercing is emerging as a more mainstream societal form of body art, and the answer to this clinical question would potentially alter patient management. Our aim was to assess serum prolactin levels in subjects with nipple piercing. Inclusion criteria were as follows: men and women ≥ 18 years old with nipple piercing(s) present > 6 months. Exclusion criteria included: women who are pregnant, lactating or < 6 months postpartum; subjects on medications known to increase prolactin levels; chest wall/breast infection at the time of phlebotomy or conditions known to be associated with hyperprolactinemia. Three men and eight women were enrolled. Median (range) ages for men and women were 33 (24-42) and 27 years (23-42), respectively. All except one subject had bilateral piercings. The median interval from nipple piercing to blood draw was 4.0 (2.0-12.0) years. None of the subjects had hyperprolactinemia. Median (range) prolactin levels for men and women were 5.6 ng/mL (3.8-7.4) and 8.0 ng/mL (2.8-10.9), respectively. Our results suggest that in the absence of any concomitant infection, chronic nipple piercing is not associated with hyperprolactinemia.

Current pharmaceutical design, 18(38), 6204-14.More infoIncreasingly more Americans are being diagnosed with diabetes mellitus, and the number of those using the continuous subcutaneous insulin infusion pump (CSII), commonly known as the insulin pump, is on the rise. Although evidence is lacking on how best to manage insulin pump patients perioperatively, several individual or institutional approaches have been developed. Here we propose a comprehensive algorithm for perioperative glycemic management in insulin pump patients undergoing noncardiac surgery. Where applicable, we discuss the rationale behind the algorithm.

- Pantalone, K. M., & Nasr, C. (2010). Approach to a low TSH level: patience is a virtue. Cleveland Clinic journal of medicine, 77(11), 803-11.More infoConfronted with a low serum level of thyrotropin (thyroid-stimulating hormone, TSH), physicians should not jump to the conclusion that it is due to a hyperthyroid state, as other conditions and some drugs can be associated with a TSH level that is slightly low (0.1-0.4 microIU/mL) or frankly suppressed (< 0.1 microIU/mL). This review discusses how to approach a low TSH, stressing the frequent need to reassess thyroid function before making a diagnosis, the underlying processes and the drugs that can be responsible, and the degree of TSH suppression and its role in the evaluation.
