Incidence and Survival in Reproductive-Aged Women with Differentiated Thyroid Cancer: United States SEER 18 2000-2016

The effects of leisure time physical activity on depression among older women depend on intensity and frequency

BACKGROUND

Leisure time physical activity (LTPA) is beneficial for late-life depression (LLD). The main purpose of this study was to estimate the associations between LTPA parameters (intensity, duration, frequency) and LLD.

METHODS

Through the 2018 Women Health Needs Survey, data on 1,892 women aged 55-70 in Hunan, China, were studied. Depression was measured by the 9-item Patient Health Questionnaire (PHQ-9). Self-reported LTPA parameters were collected. Binary logistic regression models were used to compute odds ratios (OR) for LTPA for predicting depression. Sensitivity analyses were conducted to examine the effect of missing values.

RESULTS

Moderate LTPA volume (OR = 0.582, p = 0.027, 95% CI [0.360-0.941] for 150-299 min/week and OR = 0.392, p = 0.002, 95% CI [0.215-0.714] for ≥300 min/week) was associated with reduced depression, while vigorous LTPA could increase the risk (OR = 2.414, p = 0.029, 95% CI [1.095-5.325] for <75 min/week and OR = 3.824, p = 0.007, 95% CI [1.439-10.158] for ≥75 min/week). Frequent (6-7 days/week), moderate LTPA had a lower risk (OR = 0.570, p = 0.021, 95% CI [0.353-0.918]), while frequent (≥3 days/week), vigorous LTPA increased the risk (OR = 5.103, p = 0.001, 95% CI [1.977-13.172]). The adjusted relationship between the duration and depression was not observed. The results were supported by the sensitivity analysis based on missing value replacement.

LIMITATIONS

In this cross-sectional study, LTPA data were self-reported and no data on light LTPA were collected.

CONCLUSIONS

Moderate LTPA, associated with mental health benefits, should be recommended for older women instead of vigorous LTPA.

FOXE1-Dependent Regulation of Macrophage Chemotaxis by Thyroid Cells In Vitro and In Vivo

Forkhead box E1 (FOXE1) is a lineage-restricted transcription factor involved in thyroid cancer susceptibility. Cancer-associated polymorphisms map in regulatory regions, thus affecting the extent of gene expression. We have recently shown that genetic reduction of FOXE1 dosage modifies multiple thyroid cancer phenotypes. To identify relevant effectors playing roles in thyroid cancer development, here we analyse FOXE1-induced transcriptional alterations in thyroid cells that do not express endogenous FOXE1. Expression of FOXE1 elicits cell migration, while transcriptome analysis reveals that several immune cells-related categories are highly enriched in differentially expressed genes, including several upregulated chemokines involved in macrophage recruitment. Accordingly, FOXE1-expressing cells induce chemotaxis of co-cultured monocytes. We then asked if FOXE1 was able to regulate macrophage infiltration in thyroid cancers in vivo by using a mouse model of cancer, either wild type or with only one functional FOXE1 allele. Expression of the same set of chemokines directly correlates with FOXE1 dosage, and pro-tumourigenic M2 macrophage infiltration is decreased in tumours with reduced FOXE1. These data establish a novel link between FOXE1 and macrophages recruitment in the thyroid cancer microenvironment, highlighting an unsuspected function of this gene in the crosstalk between neoplastic and immune cells that shape tumour development and progression.

Standardization of thyroid ultrasound reporting in the community setting decreases biopsy rates

OBJECTIVE

With the rising incidence of thyroid cancer, a standardized approach to the evaluation of thyroid nodules is essential. Despite the presence of multiple national guidelines detailing evaluation and management of these nodules, significant variability exists in the information that is collected and reported to clinicians from diagnostic imaging. The aim of this study was to evaluate the impact of thyroid ultrasound standardization on thyroid cancer detection in a community practice setting.

DESIGN

As part of a physician-driven quality improvement project, a multidisciplinary team created an electronic worksheet to be utilized by sonographers to capture suspicious findings based on societal guidelines and agreed on institutional criteria for recommending fine needle aspiration (FNA) of thyroid nodules.

PATIENTS

For a one-year period prior to and after the intervention, all ultrasounds performed for suspected thyroid pathology, excluding patients undergoing follow-up imaging, were reviewed at two affiliated community hospitals served by a single radiology and pathology group.

MEASUREMENTS

The number of fine needle biopsies recommended and performed, as well as the percentage of FNAs positive for malignancy were evaluated.

RESULTS

A total of 608 and 675 ultrasounds were reviewed in pre- and post-standardization periods, respectively. Following standardization, there was a similar percentage of FNAs recommended (35% vs. 37%, p = .68), fewer FNAs per total ultrasounds performed (36% vs. 31%, p = .03), fewer FNAs performed when FNA was not explicitly recommended (9.9% vs. 2.8%, p = .000046) and an increased detection of cytology consistent with, or suspicious for, malignancy (5% vs. 11.5%, p = .0028).

CONCLUSIONS

Standardization of thyroid imaging protocol and management recommendations can reduce the number of FNAs performed and increase the percentage of positive tests in a community setting.

Early Diagnosis of Low-Risk Papillary Thyroid Cancer Results Rather in Overtreatment Than a Better Survival

We are witnessing a rapid worldwide increase in the incidence of papillary thyroid carcinoma (PTC) in the last thirty years. Extensive implementation of cancer screening and wide availability of neck ultrasound or other imaging studies is the main reason responsible for this phenomenon. It resulted in a detection of a growing number of clinically asymptomatic PTCs, mainly low-risk tumors, without any beneficial impact on survival. An indolent nature of low-risk PTC, particularly papillary thyroid microcarcinoma (PTMC), and the excellent outcomes raise an ongoing discussion regarding the adequacy of treatment applied. The question of whether PTMC is overtreated or not is currently completed by another, whether PTMC requires any treatment. Current ATA guidelines propose less extensive preoperative diagnostics and, if differentiated thyroid cancer is diagnosed, less aggressive surgical approach and limit indications for postoperative radioiodine therapy. However, in intrathyroidal PTMCs in the absence of lymph node or distant metastases, active surveillance may constitute alternative management with a low progression rate of 1%-5% and without any increase in the risk of poorer outcomes related to delayed surgery in patients, in whom it was necessary. This review summarizes the current knowledge and future perspectives of active surveillance in low-risk PTC.
