CARDIAC RISKS IN PATIENTS WITH LUNG CANCER IN DYNAMICS OF CARRYING OUT RADIATION THERAPY ON LINEAR ACCELERATOR

Aim of the Research. To determine the state of cardiovascular system in patients with lung cancer (LC) during and after photon therapeutic radiation on linear accelerator for valuating risk and early diagnostics of radiation therapy complications (RT).

Materials and Methods. Clinical and instrumental examination of 35 patients with lung cancer in course of RT on linear accelerator Clinac 600C has been carried out. Clinical trial included thorough study of the state of cardiovascular system by means of analysis of patients’ complaints, results of objective methods, researches and conclusions of related specialists. Instrumental examination included ECG, echocardiogram. Bioelectrical myocardium activity and the signs of coronary insufficiency and/or heart rhythm disorder were evaluated with the help of electrocardiograph FX-326U. Radiation was carried out in conventional fractioning mode — single focal unit 2 Gy, 5 fractions a week till total focal dose of 68-70 Gy. When giving 40 Gy after the planned two-week interval control computer tomography of thorax organs was carried out. In case of absence of signs of tumor lysis and tumor process the irradiation volume was reduced to the amount of primary tumor focus and the 2nd stage of RT was carried out.

Results. The age of patients with LC in 90 % of cases exceeded 60 years. It has been shown that the initial state of such patients before RT met the determined nosological entity of cardiopathology of ischemic heart disease (IHD)with cardiac insufficiency of various degrees — in 100 % of cases, arterial hypertension — in 71 % of cases. Moderately grave conditionds was registered in the examined group in 60 % of cases, which was conditioned by pulmocardiac insufficiency. All the examined had signs of diastolic and in 29 % — systolic myocardium dysfunction, in most of them — 65,7 % on the background of preservation of ejection fraction level. Risk factors of development of oncological and cardiovascular diseases have been observed: smoking in 91 %, hypercholesterolemia — in 60 % and excess weight in 57 % of patients, burdened anamnestic record — 28,6 %, professional harmful factors — 14,3 %.On finishing of RT course progress of initial or clinically expressed signs of chronic cardiac insufficiency (CCI) on the background of arterial hypertension, IHD and/or respiratory failure have been found. Increase of amount of patients with general moderately grave conditions to 85 % cases, manifestation of clinical signs of CCI both in pulmonary and systemic circuits has been noted.

Conclusions. During RT of patients on linear accelerator progress of CCI has been pointed out. The patients with associated cardiac diseases in form of IHD, in case of combination of essential hypertension and IHD have shown increase of frequency of complications development on the part of cardiovascular system on RT in 70 % of cas-es.Rhythm disorder and asequence, clear ECG-signs of ischemia in form of repolarization processes, decrease of voltage or T waive inversion, diastolic dysfunction on insufficient relaxation type and systolic myocardium dysfunction of left ventricle are to be treated as substantial markers of cardiovascular pathology on RT. Timely diagnostics of radiation complications on the part of cardiovascular system needs dynamic patient observance, which were exposed to RT, especially in case of associated cardiac pathology with application of timely clinical and instrumental examination methods.

Keywords: cardiac risks, lung cancer, radiation therapy.

Aim. To evaluate the effectiveness of combined treatment of stage II-III rectal lower ampulla cancer based on short- or long-course neoadjuvant radiоtherapy (NRT).

Materials and Methods. А prospective multicenter randomized trial in National cancer institute, Nikolaev regional oncological hospital and Chernigov regional oncological hospital had been carried out. Two hundred and fifty one patients with low rectal cancer were included. In group I (n=150) NRT was delivered with a dose of 4-5Gy up to total dose of 15-20Gy, followed by surgery in 24-48 hours. In group II (n=101) patients received NRT in 15 days with a dose of 2Gy up to 30Gy total, followed by surgery not earlier then 3 weeks. Tumor response RECIST rate, possibility of sphincter-saving operations (SSO) after NRT, perioperative complications and longterm outcomes were assessed.

Results. In 30 (29,7 %) patients of group II partial or complete response was observed. The rate of SSO in group II was 80,2 %, in group I — 60,1 % (р < 0,005). Postoperative complications rates appeared similar in both groups (group І — 5,3 %, group ІІ — 4,9 %) (р > 0,05). Local recurrence was detected in 17 (11,3 %) of group I patients and in 6 (5,9 %) of group II. Overall 5-year survival of patients with complete and partial response was 88,6 %, patients with stable disease — 76,9 % (р = 0,038).

Conclusions. Long-course NRT demonstrates a positive impact on tumor regression, improving short- and longterm treatment outcomes. The offered method provides an opportunity to increase the rate of SSO, and in that manner, to improve patient’s quality of life.

Keywords: Rectal cancer, radiation therapy, sphincter-saving operations.

RADIONUCLIDE DIAGNOSTICS OF RECIDIVATIONS AND/OR METASTASES OF DIFFERENTIATED THYROID CANCES USING 99mТс-(V)DMSA

Abstract. Differentiated thyroid carcinoma (DTC) is the most widespread tumor of the endocrine system, but the frequency of recidivations is still high enough — from 15 to 30 %.

Diagnostic value of scintigraphy with 99mТc-(V) DMSA for early recidivations diagnostics and/or metastases of differentiated thyroid cancer was tested in 30 patients with DTC on the stage of treatment and monitoring.

The results of scintigraphy with 99mТc-(V) DMSA were compared to data of other study methods (detection of TG levels , ultrasonic scanning (US) of the neck (with NB (needle biopsy) in some cases), CT with contrast study, morphological examination and whole-body scintigraphy after receiving therapeutic activities of radioiodine).

It is proved that this method can diagnose not only locally disposed metastatic focus, but also remote metastases to the lungs. Perceptibility of scintigraphy with 99mTc-(V)DMSA was 85 %, specificity — 100 %, it attests a high informatively studies, using 99mTc-(V)DMSA for timely diagnosis of possible iodine-negativ recidivations and/or metastases of thyroid cancer.

Keywords: differentiated cancer, thyroid gland, scyntiography, recidivations diagnostics.

CYTOMORPHOLOGICAL FEATURES AND IMMUNOСУTOCHEMICAL PROFILE OF RADIOIODINE RESISTANT METASTASЕS OF PAPILLARY THYROID CARCINOMA

Summary. For the first time the authors have conducted cytomorphological and immunoсуtochemical studies of the radioiodine-resistant metastases in compare with radioiodine-uptaking metastases and with a general population of papillary thyroid cancers. The specific morphological structure, known as Nehoroshkov’s complex, and signs of cystic degeneration correlated with the radioiodine-resistance. The immunoсуtochemical studies showed predominantly a high content of thyroglobulin-positive cells in radioiodine-resistant metastases, and therefore, the presence of thyroglobulin-positive cells does not guarantee the radioiodine uptake.

We could recommend using immunocytochemical detection of thyroperoxidase-positive thyrocytes in the biop-tates of thyroid papillary metastases, found in postoperatve period. This approach allows predicting the response of metastases to radioiodine therapy in order to choose a proper therapeutic approach.

Keywords: papillary thyroid carcinoma, cytological diagnosis, prognosis, radioiodine resistant metastases, radioiodine uptake metastases, thyroid peroxidase.

DETERMINING PATHOGENETIC CONNECTION BETWEEN DISORDERS OF LIPID AND CARBOHYDRATE METABOLISM AND NON-MALIGNANT PATHOLOGY OF THYROID GLAND IN CHILDREN, BORN FROM PARENTS, CHERNOBYL ACCIDENT SURVIVORS

Summary. The 92 children aged 12-17 years were examined with the purpose to study the links between carbohydrate and lipid metabolic abnormalities and non-malignant thyroid disorders in descendants of the Chornobyl accident survivors. Clinical, anthropometrical studies and hormonal assays were applied. Carbohydrate and lipid metabolic abnormalities were revealed in every third case of thyroid disease. It confirms our supposition of such a possibility being due to the fact that radiation impact even in low doses can result in pronounced metabolic disorders leading to entire endocrine disregulation. It is especially relevant in children of the pubertal age.

Keywords: thyroid microcarcinova, radio iodine therapy, surgical treatment.

COMPLEX RADIONUCLIDE EVALUATION OF STRUCTURE-FUNCTIONAL STATE OF THE KIDNEY'S HUPOPLASY IN CHILDREN

Summary. 117 children (age ranged 5-16 years) with HK were examined by dynamic (DRSG) and static (SRSG) scintigraphy with angiography. In total 170 scintigraphic examinations with different NRP were performed: 99mTc-DTPA (diethyleneaminopentacetate) — 56, 99mTc — PP (pyrophosphate) — 52, 99m Tc — DMSA (dymethylene-succinateacetate) — 20, 99m Tc MAG3 (mercaptoacetyle-3-glycine) — 20, 99m Tc-EC (ethylenedicysteine) — 22. Time parameters of renal blood flow and transport of NRP, SGF, ERP were determined. Control group consistsed of 15 children.

The main scintigraphic features of HK are: slowdown of time parameters of renal haemodynamic, decreasing of SGF and ЕRP of SK by 2-3 times; decreasing of standard parameters SGF and ERP on 30-40 %. The slowdown of HK excretion ability is associated with NRP retention in parenchyma. Proportions of HK decrease by 35-40 % average, and the area of scintigraphic image — by 40 %. The main type of renographic curve in children with HK is parenchymatose and hypofunctional, that was found in 80 % patients. The accumulation and distribution of NRP in HK is quite uniform in 70,4 % patients.

Thus, HK in children is functionally deficient. A slowdown of all main parameters of HK functional ability dictates the necessity of permanent radionuclide monitoring.

DIFFERENTIAL SCINTIOGRAPHIC FEATURES OF LYTIC AND BLASTIC METASTASIC FOCI WITH PATIENTS WITH BC AND PC ACCORDING TO THE DATA OF 3-PHASE BONE SCYNTIGRAPHY

Summary. The objectives of the research was to determine the possibilities of 3-phase bone scyntigraphy (3-ph BSG) to reveal and carry out differential diagnostics of lytic and blastic metastatic foci in the bone tissue in patients with breast cancer (BC) and prostate cancer (PC). The data obtained in 54 patients (26 women with BC and 28 men with PC) with metastatic lesions of the bones (lytic in women with BC and blastic in men with PC) were analyzed.

On the ground of qualitative and quantitative evaluation of the results a conclusion was made that complex radio-isotipic examinaiton enables evaluating peculiarities of blood circulation and metabolic state of metastatic foci in bone tissue. Blood circulation in litic areas differs from the normal rate more essentially, than that in blastic areas, what is connected with higher heterogeneity of such areas. An average intensity of radiopharmaceutical agent retention in litic foci during both early and delayed static examination was lowered, that was conditioned by a smaller amount of trabecular elements in osteoid tissue. Radiopharmaceutical agent retention in litic foci was statically higher in compare to blastic ones due to slow blood flow therein.

Keywords: 3-phase bone scyntigraphy, lytic metastasic foci, blasitc metastasic foci.

The results of dynamic hepatobiliary scintigraphy with 99mTc-mezida in 24 children with various forms of HGN were analyzed. It has been found that it is liver parenchyma that is the most affected in children with nephrotic form of HGN. Evaluation of dynamic processes of extrahepatic bile ducts and Oddie’s sphincter in children with HGN showed that the phenomenon of spasm and cholestasis is almost unexpressed.

Keywords: pathology biliary system, biliary ways, the dynamic hepatobiliary scintigraphy, children.

SCINTIGRAPHY OPPORTUNITIES IN THE DIAGNOSIS OF TUMOR PATHOLOGY OF THE PARATHYROID GLANDS. RESULTS OF OWN RESEARCHES

Summary. Primary hyperparathyroidism is the most common cause of hypercalcemia in ambulatory healthy patients. 108 patients with pathology of parathyroid glands (PG) underwent a 99mTc-MIBI scintigraphy of parathyroid glands (PTSG). The sensitivity of PTSG in the diagnosis of neoplastic lesions was 84,44 %, the specificity — 66, 67 %, the accuracy — 83,33 %. The overall informativness of PTSG was higher than ultrasound (25 % vs. 74,07 %, respectively). The focal lesions of the parathyroid glands were diagnosed by PTSG in 80 patients (74,07 %). Negative or questionable PTSG results occurred in 28 (25,93 %) patients. The possible reasons for such results are multinodular goiter (50,0 %), thyroid maсrofollicular cavities (7,14 %), hyperplastic parathyroid glands (14,29 %), ectopic parathyroid glands (7,14 %), multiple lesions of parathyroid glands (7,14 %). In 4 patients (14,29 %) the reasons of negative results of PTSG were not found, that requires further studies.

Keywords: parathyroscintigraphy, adenoma, hyperplasia, carcinoma, parathyroid glands 99mTc-MIBI.

PROTECTIVE EFFECT OF PACLITAXEL AGAINST GAMMA-RADIATION IN AMAPLASTIC THYROID CARCINOMA CELLS

Summary. The аіт of the paper was to study the biochemical effects of Paclitaxel (Ptx), y-irradiation (IR) and then combination in undifferentiated thyroid cancer cells (ATC). There was a clear antagonism between Ptx and IR relative to cell cycle regulators — tumor suppressor p53, CHK2 and c-Abl. The net effect of these events during the first 48 h of cells incubation can be considered as antiapoptotic — Ptx attenuated cytotoxic effect of IR.

Keywords: Paclitaxel, ionizing radiation, thyroid cancer, apoptosis, cell cycle.
