Original Studies
BRAF mutation in papillary thyroid microcarcinoma – additional marker of risk stratification
Semyonov D.Y., Boriskova M.E., Zaraisky M.I., Farafonova U.V., Bikov M.A.

Abstract

Background

Papillary thyroid microcarcinoma (PTMC) is heterogeneous group of tumor less than 1 cm in the diameter. The volume of surgical treatment stay unstable because unclear biological potential of PTMC.

Aim

The aim of our study was to assess the utility of BRAF gene mutation as preoperative additional marker of risk stratification.

Materials and methods

We include 44 patient who were operated in general surgery department Pavlov State Medical University from 2001 to 2013. In all 44 cases BRAF gene mutation was detected and compared with clinic-morphological features (multifocality, invasive growth, lymph node metastasis, recurrence) retrospectively

Results

In our study the frequency of BRAF gene mutation was 68.2%. On multivariate regression analysis the presence of bilateral tumoural foci, lymph node metastasis and the presence of capsular invasion were significantly related to BRAF positive gene status.

Conclusions

Thus, appropriate volume for the BRAF positive PTMC is thyroidectomy with central compartment lymph node dissection.

Potential of the drug-regulation iodide uptake in patients for prevention of radioiodine-refractory papillary thyroid cancer
Fomin D.K., Cholak P.M., Nazarov A.A., Zacepina N.V.

Abstract

Objective

To evaluate the efficacy and feasibility of retinoic acid derivatives and lithium salts for radioiodine-refractory prevention in patients with differentiated thyroid cancer during multistage radioiodine therapy.

Materials and methods

The retrospective analysis was performed using the diagnostic and treatment results of 40 patients with differentiated thyroid cancer that underwent 131I therapy, which on the basis of posttherapy whole-body scan had direct indications for subsequent course of radioiodine therapy. The patients were divided into two groups:

  1. the control group (20 patients), which conducted a second course of radioiodine therapy on the standard template and without special training$
  2. the main group (20 patients), who were administered Sedalia (900 mg per day for 8 days, p.o.) and isotretinoin (1.2 mg/kg body weight for 60 days, p.o.) to prevention of the 131I resistance.

To evaluate the effectiveness of a repeated course of radioiodine therapy following parameters were used: the thyroglobulin (Tg) and antibodies to thyroglobulin (Tg-Ab) level in the serum, the posttherapy whole body scan in combination with SPECT-CT.

Results

We have found, that radioactive iodine treatment was effective in 75% of the main group and 90% of patients in the control group. The remission was observed in 10% and 40% in the main and control group, respectively. The partial regression was considered as Tg and TG-Ab reduction, and was observed more in the study group. The resistance to 131I therapy was found in 20% and 10% in the main and control group, respectively, which was based on the fact of permanent Tg/Tg-Ab serum level and absence of the pathological foci iodine uptake on the whole-body scans. The disease progress was found in one patient in the main group.

Conclusion

The use of retinoic acid derivatives and lithium salts, in an effort to prevent the resistance to 131I-theraphy pretend to be unjustified, because it does not lead to significant improvement in long-term results and reduce the number of 131I-resistance.

Thyroid disorders after radiation therapy in childhood
Bobrova E.I., Fadeyev V.V., Sotnikov V.M., Pavlova M.G., Sych Y.P., Semochkin S.V., Parkhomenko R.A., Mazerkina N.A., Zheludkova O.G.

Abstract

Aim

The aim of our study was to analyze thyroid status in adults after treatment for malignancies in childhood and its relationship with dose and type of radiotherapy.

Material and methods

Thyroid function (TSH, free T4, anti-TPO), thyroid ultrasound and FNA (in case of thyroid nodules more than 1 cm) were evaluated in 106 adults with a history of radiotherapy for brain tumors (BT), acute lymphoblastic leukemia (ALL) and Hodgkin's lymphoma (HL) in childhood and compared with that in healthy controls (n = 33).

  • Group 1 (cranial irradiation 18 Gy): 11 men and 17 women (median age 21.7 ± 4.2 yrs (range 15–30)), 14.6 ± 4 years after treatment for ALL.
  • Group 2 (craniospinal irradiation 35 Gy + boost to the tumor 55 Gy): 28 men and 20 women (median age 19.48 ± 2.76 yrs (range 15 – 26), 7.84 ± 4.68 years after treatment for brain tumors (BT).
  • Group 3 (local irradiation of cervix and mediastinum mean dose 30.9 ± 9.17 Gy): 13 men and 16 women (median age 28.2 ± 6.31 yrs (range 17 – 44), 11.37 ± 7.25 years after treatment for HL.

Results

Maximal incidence of hypothyroidism was in the group 2 – 58.3% (35.4% – primary, 4.2% – central, 18.8% – mixed). Prevalence of hypothyroidism in groups 1 (9.09%) and 3 (17.24%) doesn't significantly differ from controls. Thyroid volume was lower (mean 4.58±2.39 ml) in group 2 (p<0.001) in compare with other groups and control. TSH was higher (mean 3.72±2.51 MEd/l) in the same group in compare with group 1 and control (p=0.001). Incidence of thyroid nodules (10.34% – group 1; 8.3% – group 2; 20.7% – group 3) doesn't significantly differ between groups and controls (p=0.277).

Conclusions

These data indicate that treatment of cancer in childhood is associated with development of thyroid abnormality later during the life, and there is a possible link between craniospinal irradiation and incidence of hypo-thyroidism.
