Purpose: to estimate the efficiency of the concurrent chemoradiotherapy (CRT) and radiotherapy (RT) alone for patients with the locally advanced cervical cancer (CC) taking into account prognostic factors. Material and methods: The research included 335 patients with morphologically verified CC of the П-Ш stage on FIGO: 150 patients underwent RT (group 1): 185 patients - CRT with cisplatin and 5-fluorouracil (group 2). Patients in the group 1 were significantly older than patients of the group 2. The disease of the Stage III, parametric variant of the spread of the tumor, as well as metastatic lesions of the pelvic lymph nodes occurred more frequently in the group 2. Results: In the group 1 complete response to treatment occurred in 98 cases (52.9%), while in the group 2 demonstrated - 64 (42.7%) patients (p < 0.01). Radioepithelitis of Grade 1 and 2 occurred more frequently in patients underwent CRT in this group haematologic and gastrointestinal toxicity was moderate and severe...

Relevance. If a foreign body is present in a maxillary sinus, it should be surgically removed. Endoscopic and radical surgery are the main methods. Clinician’s subjective feelings determine the surgical access, which can cause complications. Therefore, the search for new methods of planning and visualizing the operation stages remains relevant.Materials and methods. Before the operation, the patient had a cone-beam computed tomography in a marker holder frame. The 3D slicer program allowed the segmentation of the foreign body and surrounding anatomical features. A marker, fixed on the patient's head, allowed transmitting information to the augmented reality glasses during the operation.Results. The surgery was performed under local anesthesia in an outpatient facility. The diameter of the antrotomy hole was 5 mm. No postoperative complications were recorded.Conclusion. The proposed technique provides significant visual control and minimal trauma to the sinus during surgery.
Three-Dimensional Planning of Brachytherapy for Locally Advanced Cervical Cancer by CT/Mri Images
Problems in oncology, 2018
We present our results of 3D CT/MRI brachytherapy (BT) planning in 115 patients with locally advanced cervical cancer T2b-3bN0-1M0. The aim of this study was to assess the differences in the visualization of tumor target volumes and risk organs during the 3D CT/MRI BT. The results of the study revealed that the use of MRI imaging for dosimetric planning of dose distribution for a given volume of a cervical tumor target was the best method of visualization of the soft tissue component of the tumor process in comparison with CT images, it allowed to differentially visualize the cervix and uterine body, directly the tumor volume. Mean D90 HR-CTV for MRI was 32.9 cm3 versus 45.9 cm3 for CT at the time of first BT, p = 0.0002, which is important for local control of the tumor process. The contouring of the organs of risk (bladder and rectum) through MRI images allows for more clearly visualizing the contours, which statistically significantly reduces the dose load for individual dosimetr...

Статья посвящена обоснованию возможности вовлечения в сферу производства селена из шламов сернокислотного цеха Балхашского медеплавильного завода (БМЗ). При пирометаллургической переработке медной шихты селен возгоняется и распределяется по четырем техногенным продуктам: промывная серная кислота, шламы сернокислотного и электролитного цехов и пыль электрофильтров. В мире основным сырьем для получения селена являются медеэлектролитные шламы (90 %) и шламы сернокислотных производств химической и целлюлознобумажной промышленности (10 %). Сопоставительный анализ содержаний селена в шламах металлургической, химической и целлюлозно-бумажной промышленности показал, что содержание селена в шламах сернокислотных цехов (СКЦ) БМЗ и АО «Кольская компания» идентично и значительно выше, чем в медеэлектролитных шламахосновном сырьевом источнике получения селена в мире.
