RESUMEN

OBJECTIVE: To increase the effectiveness of combined treatment in patients with rectal cancer and moderate risk of progression based on the concept of polyradiomodification (PRM). MATERIAL AND METHODS: The study included 337 patients with rectal cancer and moderate risk of tumor progression. A short course of radiotherapy (cRT) (5x5 Gy) combined with several radiomodifiers (cRT+PRM) was performed in 147 (43.6%) patients. Other 190 (56.4%) patients underwent cRT. The following radio modifiers were used: three-time application of local microwave hyperthermia (Yacht-3 or Yacht-4 devices), two-time intrarectal delivery of a biopolymer composition with Metronidazole before the 3rd and 5th irradiation sessions and two-week oral administration of Capecitabine (Xeloda) at a daily dose of 2.0 g/m2. Surgery was performed in 4-6 weeks after radiotherapy. RESULTS: CRT+PRM program increased 5-year relapse-free survival up to 81.3% compared to 60.3% after cRT alone (p=0.0003) due to significant reduction of the incidence of cancer recurrence from 8.4% to 0.7% (p=0.0013). More effective local growth control expanded the indications for sphincter-sparing surgery. These procedures were performed in 89.1% and 70.5% of patients, respectively (p=0.00001). In the cRT+PRM group, sphincter-sparing surgery reduced incidence of cancer recurrence from 13.7% to 0.8% (p=0.0110), distant metastases - from 23.9% to 13.7% (p=0.00349). CONCLUSION: Radiomodification in neoadjuvant radiotherapy is justified in patients with moderate risk of tumor progression, improves long-term results and increases the incidence of sphincter-sparing surgery.

RESUMEN

Acute hemorrhoids are the most common reason for referring to coloproctologist in people of working age. In the modern world, food culture and lifestyle are the most prominent factors leading to the risk of hemorrhoids. In the 21st century, it is hard to overestimate an importance of potential employability and active social role regarding socio-economic well-being. This thesis applies to patients suffering from proctological diseases, and those with hemorrhoids prevail among these ones. Minimally invasive treatment and pharmacotherapy defined primary needs of patients, i.e. treatment should be quick, safe and effective. Favorable treatment outcomes are possible only in pathogenetic therapy. In this review, we will define the priorities in effective combined treatment of hemorrhoids.

RESUMEN

AIM: In a retrospective study, we evaluated factors associated with the early development of septic shock in patients with severe COVID-19. MATERIALS AND METHODS: We collected medical records of the intensive care unit patients submitted by the local COVID-19 hospitals across Russia to the Federal Center for the Critical Care at the Sechenov First Moscow State Medical University (Sechenov University). Septic shock in crticially ill patients requiring mechanical ventilation was defined as a need in vasopressors to maintain blood pressure. RESULTS: We studied 1078 patients with severe COVID-19 who were admitted to the intensive care units for respiratory support. There were 611 males and 467 females. The mean age was 61.013.7 years. Five hundred twenty five medical records (48.7%) were received from the Moscow hospitals, 159 (14.7%) from the Moscow region, and 394 (36.5%) from the hospitals located in 58 regions of the Russian Federation. In 613 (56.9%) patients, diagnosis of SARS-CoV-2 infection was confirmed by PCR, and in the other cases it was established on the basis of the clinical picture and the results of the chest CT scan. Septic shock developed in 214 (19.9%) of 1078 patients. In the logistic regression model, the risk of septic shock in patients older than 50 years was higher than in patients of a younger age (OR 2.34; 95% CI 1.533.67; p0.0001). In patients with more severe SARS-CoV-2 infection, there was an increase in the prevalence of cardiovascular diseases, including coronary heart disease and atrial fibrillation, type 2 diabetes and malignant tumors. The risk of septic shock in patients with three or more concomitant diseases was higher than in patients without any concomitant chronic diseases (OR 1.76; 95% CI 1.762.70). CONCLUSION: The risk of septic shock in patients with acute respiratory distress syndrome induced by SARS-CoV-2 is higher in patients older than 50 years with concomitant diseases, although a severe course of the disease is also possible in younger patients without any concomitant disorders.

RESUMEN

The modern model of inpatient surgical care of private and optimized state/govermental medical institutions allows us to change the paradigm of nosological attachment of the hospital bed to one profile of specialists for an adaptive model, when the wards can be reassigned depending on the needs of the hospital. In such multidisciplinary medical centers with mixed hospital beds without a nominal distinction in the nosological departments, a new therapeutic service is being developed - hospitalists, which provide a consistent curation of hospitalized patients, compensation of chronic therapeutic illnesses with patient's preparation for surgical interventions. Our work describes the experience of Fast Track recovery program with the active participation of a hospitalist in a surgical team, which is a new experience in the practice of Russian colorectal surgery.

RESUMEN

AIM: To study cerebral autoregulation (CA) in region of the stenotic carotid artery. MATERIAL AND METHODS: The study involved 35 patients with critical stenosis of the carotid arteries, including 24 patients were asymptomatic and 11 patients with symptomatic course. Blood flow velocity in middle cerebral arteries was monitored using Multi Dop X (DWL, Germany) with simultaneous noninvasive systemic blood pressure registration (CNAP, Austria). CA was assessed by calculating the phase shift (PS) between spontaneous oscillations of blood flow velocity and blood pressure within the range of systemic Mayer waves (80-120 mHz). RESULTS: In 18 patients, the CA indicators were in the normal range (PS 1.2±0.3 rad). Seventeen patients, including asymptomatic as well as symptomatic types, had impaired CA (PS 0.2±0.2 rad and 0.3±0.2 rad, respectively). Reconstructive surgery, irrespective of clinical manifestations, led to the significant increase in PS (p<0.001) in the early postoperative period (0.9±0.5 and 0.9±0.3 rad, respectively). CONCLUSION: A significant variability in the cerebrovascular reserve capacity in symptomatic and asymptomatic types of carotid artery stenosis was found. CA can be used in determining the indications for surgical treatment and evaluation of its effectiveness in patients with stenosis of carotid arteries.

RESUMEN

AIM: To present early and remote surgical outcomes in patients with locally-advanced right-sided colonic cancer, invasion of pancreatic head and/or duodenal wall. MATERIAL AND METHODS: Early and remote surgical outcomes were analyzed in 27 patients who underwent gastropancreatoduodenectomy combined with right-sided hemicolectomy (ileotransversostomy extirpation) for locally-advanced right-sided colonic cancer. RESULTS: Mean time of surgery was 300 (240-460) minutes, intraoperative blood loss - 2000 (500-7200) ml. Postoperative complications were observed in 15 (55.6%) patients. 3 (11.1%) patients died in early postoperative period. Overall 1-, 3- and 5-year survival was 92.7%, 48% and 36,5% respectively. Median was 33 months. CONCLUSION: Advanced combined surgery for locally-advanced right-sided colonic cancer, invasion of pancreatic head and/or duodenal wall is associated with acceptable incidence of postoperative complications, early and long-term mortality.

RESUMEN

During recent decades radiotherapy is the basis, on which it is built a medical complex that is the first-line treatment of patients with squamous cell carcinoma of the anal canal. An increase of overall and disease-free survival and quality of life of patients with squamous cell carcinoma of the anal canal at the present stage of development of a comprehensive medical treatment is largely due to the improvement of technical equipment of radiotherapy departments of oncology clinics. The use of modem linear electron accelerators and systems of computer dosimetric planning to create a 3D program of isodose distribution, diagnostic devices (computed tomography and magnetic resonance imaging) as well as a number of other conditions permit accurate summarizing of proposed dose, reducing of absorbed dose to critical structures, diminishing unplanned interruptions in chemoradiotherapy course by means of modern technologies of conformal radiotherapy (3D CRT, IMRT, VMAT). The paper presents the preliminary results of a comprehensive medical treatment of 14 patients with squamous cell carcinoma of the anal canal.

RESUMEN

Somatic mutations of KRAS, PIK3CA, and BRAF cause insensitivity of colorectal tumors to therapy with anti-EGFR monoclonal antibodies, necessitating a genetic testing prior to therapy. A biological microchip was developed and validated to allow detection of 19 somatic mutations in KRAS, PIK3CA, and BRAF genes. The method combines LNA-clamp PCR and allele-specific hybridization on a microchip and detects mutant DNA in 100 times wild-type background (1%). A total of 66 DNA samples isolated from colorectal tumors were tested with the biochip. Possible associations between the genetic status of the tumor and the patient's characteristics (age, sex, tumor localization, stage, and TMN) were assessed statistically. KRAS mutations were more common in females (P = 0.02) and in patients with distant metastasis (P = 0.04). Other associations between the presence of mutations and patient characteristics were not observed. The method proved highly sensitive and can be used in oncology to select patients who sensitive to therapy with anti-EGFR monoclonal antibodies.

RESUMEN

Colorectal cancer is one of the most common cancers in the world. In our work changes of AKR1B1 and AKR1B10 gene expression levels in colorectal tumors were studied. Their potential diagnostic value was previously shown for several other cancer types. These genes encode aldoso reductases, which belong to the aldo-keto reductases superfamily consisting of enzymes capable to reduce numerous aromatic and aliphatic aldehydes and ketones. They are also involved into retinoid metabolism and cancerogenesis. We have carried out comparative analysis of mRNA levels of AKR1B1 and AKR1B10 genes in paired samples of normal and colorectal tumor tissues using RT-PCR and quantitative PCR. We have shown for the first time the decrease of activity of these genes in colorectal carcinomas. Significant reduction of AKR1B10 mRNA level was detected in the most of tumor samples (88%, 65/74) even at the early stages of malignancy, and in more than 60% of cases this downregulation was much higher than 10 folds. The decrease of AKR1B1 mRNA level was shown in 10% of tumors only. Therefore, we have detected quite different mRNA expression patterns in colorectal cancer for these two structurally similar genes. These data could indicate different functional roles of these two genes in colorectum. The significant decrease of AKR1B10 mRNA in most samples of colorectal cancer could be considered as potential diagnostic marker of this type of cancer.

RESUMEN

The report discusses our 30-year experience with surgical and combined treatment of rectal cancer. In cases of preoperative radiotherapy, loco-regional frequency of relapse dropped to 9.6% as compared with surgery (16.3%). After preoperative thermoradiotherapy it fell to 4.6%; polyradiomodification - 0.5% (3-year follow-up). Distant metastasis formation rates were: after polyradiomodification--1.5%, radiotherapy--9.6%, and thermo-radiotherapy--6%. Recurrence-free survival rates (3 years) were: polyradiomodification--97.3%, thermo-radiotherapy--75.9%, radiotherapy--71.1%, and surgery--58%. Data on regimens and dosage of polyradiomodification alongside radiation damage for different combinations of treatment are presented.

RESUMEN

The paper presents an evaluation of the results of surgical and combined treatment received by 961 patients at the Center's Clinics within 28 years. The analysis was based on 3 protocols of prospective randomized study. It dealt with assessment of the end results of surgical and combined treatment for operable rectal cancer using one preoperative hyperfractonated STD of 5-25 Gy. That was combined with local microwave hyperthermia and two radio modifiers--local microwave hyperthermia+intrarectal administration of a preparation containing metronidazolum. Due to the latter factor, the rate of 3-year relapse-free survival rose considerably. Also, loco-regional and distant metastasis incidence was cut down due to superior ablasticity of surgery.

RESUMEN

The purpose of this study was to evaluate dynamics of B-waves' amplitudes (BWA) of blood flow velocity (BFV) in patients with cerebrovascular diseases during endovascular operations. We examined 12 patients with neurovascular pathology during neuroendovascular interventions. Patients were divided into two groups: 1st group (6 cases)--without intraoperative neurological complications, 2nd group (6 cases)--with complications. Bilateral monitoring of BFV in middle cerebral arteries was carried out applying Multi Dop X. To estimate BWA Fourier analysis was used. In the 1st group preoperative BWA on the affected side was 3.9 +/- 0.6 cm/s. Intraoperative (during an access to pathologic formation and its embolisation) BWA increased up to 7.7 +/- 1.1 cm/s (p < 0.05). Postoperative BWA decreased to 4.2 +/- 0.8 cm/s. In the 2nd group the preoperative BWA on the affected side was 9.6 +/- 1.1 cm/s (p < 0.05), thus higher than in the 1st group. Intraoperatively we observed further increase of BWA up to 12.1 +/- 2.6 cm/s, accompanied by occurrence or increase of neurological symptoms. Postoperative BWA decreased to 10.4 +/- 2.9 cm/s, whereas we didn't observe regression of neurological symptoms.

RESUMEN

Preoperative dynamic autoregulatory responses in 20 patients considered as candidates for vessel temporal clipping (TC) and/or arterial hypotension (AH) at surgery for aneurysms were studied by the thigh cuff method. Normal autoregulatory responses at a regulation rate (RoR) of 20.4 +/- 2.8%/s were found in 10 patients > 30 days after subarachnoidal hemorrhage (SH) while RoR was 12.5 +/- 2.5%/s in 10 other patients (30 days, grade III WFNS showed autoregulation impairment. TC and/or AH were proceeded in 17 operated patients. One postoperative death was due to pulmonary embolism. Two poor results with persistent neurological disorders at discharge were associated with TC but in 1 patient. This patient had severe vasospasm and the lowest RoR (9%/s). There were no TC and/or AH postoperative complications in other 14 patients. All of them and 3 other patients with direct aneurysm clipping had a fair outcome.

RESUMEN

Fibronectin is a high-molecular polyfunctional glycoprotein occurring in the majority of the body fluids and tissues. Various investigations have demonstrated that plasma fibronectin levels either fail to change, or increase with longer gestation during a normal pregnancy. The time course of changes in fibronectin levels has been found to become lower in the amniotic fluid during pregnancy, though its physiological role has not been defined in this case. In late gestosis, plasma fibronectin concentrations substantially rises as compared to those observed in normal pregnancy.

RESUMEN

The study was undertaken to analyze correlation of 25 indicators characterizing schoolchildren's health status from the cell level up to the body one. There were established some characteristics of forming inner damaging mechanism appearing in the body because of deviations in children's physical development. Body weight deficiency was characterized by high integration of diverse signs, whereas excessive body weight was accompanied by sharp discoordination of interlevel interaction. Low stature was described by links' desynchronization at the cellular and tissue levels that was accompanied by a rupture of relations of the functional systems of the given order with the body level, here interlevel links were indirectly supported.
