POSSIBILITIES OF OBTAINING RADIOPHARMACEUTICALS «GLUCOSE, 11C» AND «ETHANOL, 11C» FOR PET TOMOGRAPHY ON ACCELERATORS OF NSC KHIPT

Ultra-short-lived isotopes 18F and 11C for positron emission tomography (PET) are usually obtained using a cyclotron proton accelerator or by photonuclear method using linear electron accelerator or microtron. In the NSC KhIPT, the possibility of obtaining new radiopharmaceuticals labeled with the 11C isotope, ready for use for PET diagnostics and treatment, has been successfully implemented in practice. The prerequisite for the effective operation of the PET center is the placement of the accelerator in close proximity to the PET tomograph. Such a condition is satisfied in the proposed PET center version. The PET tomograph and accelerators (cyclotron, microtron) are suggested to be located in the existing neighboring buildings of the KhNU. Transportation of the pharmaceuticals labeled with isotopes 11C and 18F is planned to be carried out by means of pneumatic mail.
Implementation of the Proposal will allow establishing not simply a typical PET diagnostic center in the Kharkiv region. A unique cancer center will be established based on the new radiopharmaceuticals «Ethanol, 11C». These radiopharmaceuticals are already obtained by the researchers of the NSC KhIPT of the National Academy of Sciences of Ukraine after the development of the method for cancer treatment with normal ethanol in the United States.
Keywords: positron emission tomography, cyclotron, microtron, radiopharmaceutical, «Glucose, 11C», «Ethanol, 11C», cancer treatment.

THE IMPACT OF THE COMBINED ACTIONS OF CONFORMAL RADIATION THERAPY AND COX-2 INHIBITOR ON CONTENTS OF VEGF, COX-2, PGE-2 IN SERUM OF PATIENTS WITH NON-SMALL CELL LUNG CANCER

The purpose of the work. To study of influence of combined actions of conformal radiation therapy and COX-2 inhibitor on treatment effectiveness and content of VEGF, COX-2 and PGE 2 in serum of patients with non-small cell lung cancer.
Materials and methods. To assess The results.of the study 28 NSCLC aged 54 to 73 years were divided into two subgroups: 1-subgroup (10 patients who received radiation therapy (RT) in combination with the inhibitor of COX-2-ranseleks), 2- subgroup (18 patients who conducted RT). Radiation therapy is conducted using the techniques of conformal irradiation on Clinac linear accelerator 600 c. In the first phase RT patients received an inhibitor of COX-2-ranseleks 100 mg per day. For the determination of factors of angiogenesis VEGF, COX-2 and PGE-2 patients blood sampling carried out prior to the exposure and after radiotherapy. Level indicators were determined in blood.
The results. Found that when using conformal radiotherapy combined with a COX-2 inhibitor positive effect was observed in 80 % of patients with NSCLC. Partial regression prevailed whose frequency increased in patients with NSCLC in 4.5 times. However, local radiation reactions do not exceed 2nd class, hematological toxicity-1st degree. Found raising the content of VEGF in serum of 89 % of NSCLC, in 92.8 % of COX-2 and PGE-2 before treatment, indicating the activation of the angiogenesis processes. The dependence of the expression of VEGF, COX-2 and PGE-2 from stage of the disease and lesions of lymph node in patients with NSCLC. Found that levels of COX-2 and PGE-2 remain high after RT, indicating their resistance to irradiation in patients with NSCLC. It has been proven that influenced by the combined action of RT and inhibitor of COX-2-ranseleks reduces the content of VEGF, COX-2 and PGE 2 in serum of patients with NSCLC.
Conclusions. Dynamic changes in VEGF, COX-2 and PGE 2 in serum of patients with NSCLC, with the combined action of RT and inhibitor of COX-2-ranseleks were defined. It is shown that the combined action of RT and inhibitor of COX-2 reduces the level of VEGF, COX-2 and PGE 2 in serum of patients with NSCLC that points to a slowing of tumor angiogenesis.
Keywords: radiation therapy (RT), inhibitor of COX-2, vascular endothelial growth factor (VEGF), angiogenesis, cyclooxygenase-2 (COX-2), prostaglandin E-2 (PGE-2), non-small-cell lung cancer (NSCLC).

INTERVENTIONAL RADIOLOGY IN THE TREATMENT OF IATROGENIC URETERAL INJURY

Two clinical cases of minimally invasive treatment of patients with iatrogenic injury of the ureter and the formation of ureterovaginal fistulas have been described. The development of this complication in most cases requires an open surgical procedure, however, adhesions, inflammatory changes make it difficult to perform reconstructive surgery. The use of interventional radiology methods, such as ureteral stenting, makes possible to close an established fistula with minimal invasiveness and restore the integrity of the organ. At the same time, the destruction of ureter wall and the presence of urine leak greatly complicates the passage of the damage zone both antegrade through nephrostomy access, and retrograde using cystoscopy. We have used the «rendezvous technique», the combined use of nephrostomy and cystoscopic approaches, that allows ureteral stenting in such difficult situations
Keywords: iatrogenic ureteral injury, interventional radiology, ureteral stenting, «Rendezvous» technique.

ROLE OF IN VIVO DOSIMETRY IN QUALITY ASSURANCE OF RADIATION THERAPY FOR PROSTATE CANCER

Objective. Assess in vivo dosimetry capabilities for monitoring the quality of external beam radiation therapy for prostate cancer and conduct a comparative analysis of calculated and actual doses to organs at risk using semiconductor detectors located on the anterior wall of the rectum and the posterior wall of the bladder.
Materials and methods. The study involved 63 patients with prostate cancer T1–T3a stage, without distant metastases. Radiation therapy was carried out in a total dose of 74 Gy, 34 fractions, 5 days a week using a static four-field method. In vivo dosimetry was performed once a week using semiconductor dosimeters located on the anterior wall of the rectum and the posterior wall of the bladder.
Results. The calculated and actual dose data on the posterior wall of the bladder and the anterior wall of the rectum (which are the main critical organs in radiation therapy of this localization) was compared.The average deviation of the measured dose from the calculated one by planning system on the posterior wall of the bladder was 1.17 % ± 0.17 %, on the anterior wall of the rectum — 0.99 % ± 0.18 %.
Conclusions. The measurement results obtained in this work show the accuracy of in vivo dosimetry (using semiconductor dosimeters) and allow the secondary verification of plans in radiation therapy to be made. These type of dosimetry is able to measure the dose inside the patient’s body in close proximity to the irradiated volume with high accuracy and can be used without significant changes in the clinical workflow.
Keywords: іn vivo dosimetry, prostate cancer, remote radiation therapy, quality control, organs at risk, the amount of radiation.

LEPTIN AND BREAST CANCER

Obesity is a risk factor for the development and accelerated progression of various malignant tumors, including breast cancer. Adipokines play a significant role in the realization of the connection between obesity and breast cancer. A key mediator of obesity effects on carcinogenesis is leptin, the circulating level of which is proportional to fat mass. This review summarizes the results of studies indicating the relationship of leptin with the risk of developing and progression of breast cancer and highlights the mechanisms of procarcinogenic action of the hormone and leptin-directed therapeutic approaches.
Keywords: leptin, breast cancer.

HEART RATE VARIABILITY IN OBESE ENDOMETRIAL CANCER PATIENTS

Purpose of the study. To reveal peculiarities of autonomic regulation, determined by heart rate variability (HRV) indices, in endometrial cancer patients with different degrees of obesity.
Materials and methods. The study enrolled 63 patients with stages I–II endometrial cancer (EC) (T1а-bN0M0– T2a-bN0M0) who had undergone total hysterectomy. The study of HRV was performed using the Spectrum + diagnostic complex. HRV was analyzed by means of methods of temporal and spectral analysis and the variation pulsometry method. Indicators of HRV were analyzed in groups of patients who differed by body mass index.
Results. In patients with obesity, a decrease in HRV was recorded. The total signal power of vegetative influences in the group with normal weight was 1561 ms2. In groups with I, II and III degrees of obesity, this indicator was 1202 ms2, 998 ms2 and 432 ms2, respectively. The lowest rates of temporal and spectral analysis of HRV were recorded in patients with degreе III obesity. These patients also had a high stress index of regulatory systems. Correlations between body mass index and HRV indices have been established.
Conclusions. In endometrial cancer patients with obesity, a decrease in HRV was observed, which indicates the prevalence of sympathetic influences in these patients. The degree of disturbance of vegetative influences is directly dependent on the degree of obesity. Lifestyle changes aimed at normalizing body weight can be recommended to prevent disturbances of autonomic regulation and reduce the risk of endometrial cancer.
Keywords: endometrial cancer, obesity, heart rate variability.
