Abstract

Objectives: Thyroid benign (TBN) and malignant (TMN) nodules are a common thyroid lesion. The differentiation of TMN often remains a clinical challenge and further improvements of TMN diagnostic accuracy are warranted. The aim of present study was to evaluate possibilities of using differences in chemical elements (ChEs) contents in nodular tissue for diagnosis of thyroid malignancy.

Methods: Contents of nineteen ChEs including aluminum (Al), boron (B), barium (Ba), calcium (Ca), chlorine (Cl), coper (Cu), iron (Fe), I (iodine), potassium (K), lithium (Li), magnesium (Mg), manganese (Mn), sodium (Na), phosphorus (P), sulfur (S), silicon (Si), strontium (Sr), vanadium (V), and zinc (Zn) were prospectively evaluated in nodular tissue of thyroids with TBN (79 patients) and to TMN (41 patients). Measurements were performed using a combination of non-destructive and destructive methods: instrumental neutron activation analysis and inductively coupled plasma atomic emission spectrometry. 

Results: that in TMN tissue means of Br, I, Na, S, and V mass fractions are approximately 2.9, 15, 1.25, 1.15, and 1.7 times, respectively, lower, while the means of Ca, K, Mg, and P mass fraction are 2.3, 1.4, 1.4, and 2.0 times, respectively, higher those in TBN tissue. Mean contents of Al, B, Ba, Cl, Cu, Fe, Li, Mn, Si, Sr, and Zn found in the TBN and TMN groups of nodular tissue samples were similar.

Conclusions: It was proposed to use the I mass fraction as well as I/Ca, I/K, I/Mg, and I/P mass fraction ratios in a needle-biopsy of thyroid nodules as a potential tool to diagnose thyroid malignancy. Further studies on larger number of samples are required to confirm our findings and proposals.

Introduction

Nodules are a common thyroid lesion, particularly in women. Depending on the method of examination and general population, thyroid nodules (TNs) have an incidence of 19–68% [1]. In clinical practice, TNs are classified into benign (TBN) and malignant (TMN), and among all TNs approximately 10% are TMN [2]. It is appropriate mention here that the incidence of TMN is increasing rapidly (about 5

Material and Methods

All patients suffered from TBN (n=79, mean age M±SD was 44±11 years, range 22-64) and from TMN (n=41, mean age M±SD was 46±15 years, range 16-75) were hospitalized in the Head and Neck Department of the Medical Radiological Research Centre (MRRC), Obninsk. Thick-needle puncture biopsy of suspicious nodules of the thyroid was performed for every patient, to permit morphological study of thyroid tissue at these sites and to estimate their ChEs contents. In all cases the diagnosis has been confirmed by clinical and morphological results obtained during studies of biopsy and resected materials. Histological conclusions for TBN were: 46 colloid goiter, 19 thyroid adenoma, 8 Hashimoto's thyroiditis, and 6 Riedel’s Struma, whereas for TMN were: 25 papillary adenocarcinomas, 8 follicular adenocarcinomas, 7 solid carcinomas, and 1 reticulosarcoma. Samples of nodular tissue for ChEs analysis were taken from both biopsy and resected materials.

All studies were approved by the Ethical Committees of MRRC. All the procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments, or with comparable ethical standards. Informed consent was obtained from all individual participants included in the study.

All tissue samples obtained from TBN and TMN were divided into two portions using a titanium scalpel to prevent contamination by ChEs of stainless steel [50]. One was used for morphological study while the other was intended for ChEs analysis. After the samples for ChEs analysis were weighed, they were freeze-dried and homogenized [51]. The pounded samples weighing about 10 mg (for biopsy) and 100 mg (for resected materials) were used for ChE measurement by INAA-SLR. The content of Ca, Cl, I, K, Mg, Mn, and Na were determined by INAA-SLR using a horizontal channel equipped with the pneumatic rabbit system of the WWR-c research nuclear reactor (Branch of Karpov Institute, Obninsk). After non-destructive INAA-SLR investigation the thyroid samples were used for ICP-AES. The samples were decomposed in autoclaves and aliquots of solutions were used to determine the Al, B, Ba, Ca, Cu, Fe, K, Li, Mg, Mn, Na, P, S, Si, Sr, V, and Zn mass fractions by ICP-AES using the Spectrometer ICAP-61 (Thermo Jarrell Ash, USA). Information detailing with the NAA-SLR and ICP-AES methods used and other details of the analysis were presented in our earlier publications concerning ChE contents in human thyroid [33,34], prostate [52-56], and scalp hair [57,58].

To determine contents of the ChE by comparison with a known standard, biological synthetic standards (BSS) prepared from phenol-formaldehyde resins were used [59]. In addition to BSS, aliquots of commercial, chemically pure compounds were also used as standards. Ten sub-samples of certified reference material (CRM) IAEA H-4 (animal muscle) and five sub-samples of CRM of the Institute of Nuclear Chemistry and Technology (INCT, Warszawa, Poland) INCT-SBF-4 Soya Bean Flour, INCT-TL-1 Tea Leaves, and INCT-MPH-2 Mixed Polish Herbs were treated and analyzed in the same conditions that thyroid samples to estimate the precision and accuracy of results 

A dedicated computer program for INAA-SLR mode optimization was used [60]. All thyroid samples for ChEs analysis were prepared in duplicate and mean values of ChEs contents were used in final calculation. Mean values of ChE contents were used in final calculation for the Ca, K, Mg, Mn, and Na mass fractions measured by two methods. Using Microsoft Office Excel software, a summary of the statistics, including, arithmetic mean, standard deviation of mean, standard error of mean, minimum and maximum values, median, percentiles with 0.025 and 0.975 levels was calculated for ChEs contents in two groups of nodular tissue (TBN and TMN). The difference in the results between two groups of samples was evaluated by the parametric Student’s t-test and non-parametric Wilcoxon-Mann-Whitney U-test.

Discussion

As was shown before [33,34,52-58] good agreement of the Al, B, Ba, Ca, Cl, Cu, Fe, I, K, Li, Mg, Mn, Na, P, S, Si, Sr, V, and Zn contents in CRM IAEA H-4, INCT-SBF-4, INCT-TL-1, and INCT-MPH-2 samples determined by both INAA-SLR and ICP-AES methods with the certified data of these CRMs indicates acceptable accuracy of the results obtained in the study of TBN and TMN groups of tissue samples presented in Tables 1-3. 

From Table 2, it is observed that in TMN tissue means of Br, I, Na, S, and V mass fractions are approximately 2.9, 15, 1.25, 1.15, and 1.7 times, respectively, lower, while the means of Ca, K, Mg, and P mass fraction are 2.3, 1.4, 1.4, and 2.0 times, respectively, higher those in TBN tissue. In a general sense means of Al, B, Ba, Cl, Cu, Fe, Li, Mn, Si, Sr, and Zn contents found in the TBN and TMN groups of tissue samples were similar (Table 2). 

Mean values obtained for Al, Ba, Br, Ca, Cu, Fe, I, Mn, S, Si, Sr, and Zn contents in TBN (Table 3) agree well with median of mean values reported by other researches [61-67,68-72,75-77]. Mean mass fractions of Cl and Na in TBN obtained in present study were almost one order of magnitude and 3 times, respectively, higher while mean mass fraction of P was 1.6 time lower those in only published article on Cl [67], Na [62], and P [66]. Mean mass fraction of K in TBN obtained in present study was a little higher the upper value of range of published means {66], whereas mean mass fraction of Mg was a little lower the lowest value of range of published means {73]. Mean mass fraction obtained for V in TMN was almost two order of magnitude lower median of previously reported means 63,67] No published data referring B and Li contents in TMN were found (Table 3). 

Mean values obtained for Ca, Cu, Fe, I, Mg, Mn, and Zn contents in TMN (Table 3) agree well with median of mean values reported by other researches [64,67,73,75,77-81]. Mean mass fraction obtained for Br in TMN was almost one order of magnitude higher median of previously reported means but inside the range of means [78,70]. Mean mass fraction of K founded in TMN was a little higher the upper value of range of published means {64], while mean mass fraction of Cl was almost one order of magnitude higher that in only published article on this ChE content in malignant thyroid [67]. Mean mass fractions of V in TMN obtained in present study was approximately three orders of magnitude lower the only reported value [67]. No published data referring Al, B, Ba, Li, Na, P, S, Si, and Sr of TMN were found (Table 3). .

The range of means of Al, Ca, Cu, Fe, I, K, Mg, Mn, Sr, V, and Zn level reported in the literature for TNs vary widely (Table 3). This can be explained by a dependence of ChEs content on many factors, including age, gender, ethnicity, mass of the TNs, and the stage of diseases. Not all these factors were strictly controlled in cited studies. However, in our opinion, the leading causes of inter-observer variability can be attributed to the accuracy of the analytical techniques, sample preparation methods, and inability of taking uniform samples from the affected tissues. It was insufficient quality control of results in these studies. In many scientific reports, tissue samples were ashed or dried at high temperature for many hours. In other cases, thyroid samples were treated with solvents (distilled water, ethanol, formalin etc). There is evidence that during ashing, drying and digestion at high temperature some quantities of certain ChEs are lost as a result of this treatment. That concerns not only such volatile halogen as Br, but also other ChEs investigated in the study [84-86]. On the other hand, when destructive analytical techniques are used, the tissue samples may be contaminated by ChEs contained in chemicals using for digestion. 

Elemental analysis of affected thyroid tissue could become a powerful diagnostic tool. To a large extent, the resumption of the search for new methods for early diagnosis of TMN was due to experience gained in a critical assessment of the limited capacity of the US-examination [2,3]. In addition to the US-test and morphological study of needle-biopsy of the TNs, the development of other highly precise testing methods seems to be very useful. Experimental conditions of the present study were approximated to the hospital conditions as closely as possible. In all cases we analyzed a part of the material obtained from a puncture biopsy of the TNs. Therefore, our data allow us to evaluate adequately the importance of ChEs content information for distinguish TMN from TBN. 

Tissue content of Br, Ca, I, K, Mg, Na, P, S, and V are different in most TMN as compared to TBN (Tables 2). It should be noted, however, that Br compounds, especially potassium bromide (KBr), sodium bromide (NaBr), and ammonium bromide (NH4Br), are a component of many tranquilizers and frequently used as sedatives, for example, in Russia [87]. Uncontrolled use of tranquilizers may be the reason for elevated levels of Br in specimens of patients with TNs. Therefore, for diagnostic purposes, data for Br content should be used with caution. Level of I in nodular tissue has very promising prospects as a biomarker of malignancy, because there is a great difference between content of this ChE in TBN and TMN (Tables 2). It is very interest a potential possibilities of using the I/Ca, I/K, I/Mg, and I/P ratios as cancer biomarker, because during the thyroid malignant transformation contents of these ChEs in nodular tissue change in different directions – a drastically decrease of I and an increase of Ca, K, Mg, and P (Tables 2). Thus, the results of study show that determination of ChEs contents in biopsy of TNs may serve as a potential tool for accurate detection of TMN.

This study has several limitations. Firstly, analytical technique employed in this study measure only nineteen ChEs (Al, B, Ba, Ca, Cl, Cu, Fe, I, K, Li, Mg, Mn, Na, P, S, Si, Sr, V, and Zn) mass fractions. Future studies should be directed toward using other analytical methods which will extend the list of ChEs investigated in TBN and TMN. Secondly, the sample size of TBN and TMN group was relatively small and prevented investigations of ChEs contents in these groups using differentials like gender, functional activity of nodules, stage of disease, and dietary habits of patients with TNs. Lastly, generalization of our results may be limited to Russian population. Despite these limitations, this study provides evidence on significant ChEs level alteration in thyroid nodular tissue and shows the necessity to continue ChEs research as potential biomarkers of thyroid malignant transformation.

Conclusion

In this work, elemental analysis was carried out in the nodular tissue samples of thyroid with TBN and TMN using a combination of nuclear analytical methods. It was shown that a combination of three methods such as EDXRF, INAA-SLR and INAA-LLR is an adequate analytical tool for the non-destructive determination of Ag, Ca, Cl, Co, Cr, Cu, Fe, Hg, I, K, Mg, Mn, Na, Rb, Sb, Sc, Se, Sr, and Zn content in the tissue samples of human thyroid, including needle-biopsy. 

It was observed that in TMN tissue means of Br, I, Na, S, and V mass fractions are approximately 2.9, 15, 1.25, 1.15, and 1.7 times, respectively, lower, while the means of Ca, K, Mg, and P mass fraction are 2.3, 1.4, 1.4, and 2.0 times, respectively, higher those in TBN tissue. Mean contents of Al, B, Ba, Cl, Cu, Fe, Li, Mn, Si, Sr, and Zn found in the TBN and TMN groups of nodular tissue samples were similar. In our opinion, the drastically decrease in level I and abnormal increase in level Ca, K, Mg, and P in thyroid nodular tissue could be a specific consequence of malignant transformation. It was proposed to use the I mass fraction as well as I/Ca, I/K, I/Mg, and I/P mass fraction ratios in a needle-biopsy of thyroid nodules as a potential tool to diagnose thyroid malignancy. Further studies on larger number of samples are required to confirm our findings and proposals.
