V současnosti neexistuje standardní léčba cílená na inhibici HER2 pro pacientky s metastatickým HER2-pozitivním karcinomem prsu po progresi na léčbě trastuzumabem a lapatinibem. V retrospektivních studiích se prokázalo, že trastuzumab si může v této situaci zachovávat terapeutickou aktivitu a být validní léčebnou možností pro pacientky v dobrém celkovém stavu., Currently there are no standard therapeutical options for patients with metastatic HER2-positive breast cancer after progression on trastuzumab and lapatinib. Retrospective studies have indicated promising activity of trastuzumab retreatment in this clinical situation. Trastuzumab may therefore represent a valid treatment option for these patients in good overall condition., Tomáš Büchler, and Literatura 6
Aim: to improve treatment results of colorectal cancer, complicated carcinomatosis of abdominal cavity, by associated using of endolymphatic chemotherapy (ELCT) and local extremely high frequency (EHF) therapy. Igroup 21 people (33.3%) performed colostomy, then neoadjuvant systemic chemotherapy by the scheme FOLFOX4. It was held two cycles, after two cycles their were received cytoreductive surgery; II group 26 people (41,3%) received cytoreductive operations with early postoperative intraabdominal chemotherapy by oxaliplatin (200 mg/m(2) at day 1 and 5FU 650 mg/m(2) from days 1 to 4. III group 16 people (25,4%) also performed colostomy, then used 2 courses of ELCT with local EHF therapy and all patients were received cytoreductive operations. ELCT was carried out injecting oxaliplatin100 mg/m(2) a day during 12 hours and then 5 FU in doze of 600 mg/m2 a day during 72 hours by the instrumentality of the dozer and LV200 mg/m(2) (2h intravenous infusion). During ELCT patients received local EHF therapy in abdominal cavity for an hour. After chemotherapy the partial regress of tumor observed in 1st group in 4,8 % and in 3rd 37,5 %, stabilization of process noted in 28,6 and 50% cases, progressing 66,7 and 12,5% cases correspondingly to groups. Histomorphologic study of malignant foci after ELCT+EHF therapy showed reduction of specific area of parenchyma cancer cell from 57 till 39% simultaneous growth of stroma from 40 till 58% and in necrosis area from 1,8 till 2,5%. Mitotic activity of tumor cells in the 1st group decreased (average in 22 un.), but in 3rd group it decreased until 11 units. Analysis of life span showed that in 1st group of patients 2year survival rate was 66,7%. In 2nd group of patients 2year survival rate was 42,3%. ELCH+EHFtherapy has high clinic efficacy and promotes to decrease terms of progression of tumor process, increases life span from 0 till 24% and quality of life of the patients. ELCH+EHFtherapy brings to reduction of specific area of parenchyma in cancer cells from 57 till 39% with simultaneous growth of stroma area from 40 till 58% and necrosis area from 1,8 till 2,5%. ELCT+EHFtherapy lowers mitotic activity of tumor cells, activates apoptosis, hemodynamic and metabolic rates., Akbarov E.T., Navruzov S.N., Abdujapparov S.B., Islamov H.D., and Literatura
Maligní melanom je nejagresivnější kožní nádor. Incidence tohoto onemocnění roste rychleji než u jiných malignit a stále více postihuje mladé lidi. Standardní léčba založená na chemoterapii nebo biochemoterapii nedokázala prodloužit přežití. Pokroky v oblasti imunologie a molekulární biologie u melanomu umožnily objevení nových potenciálních cílů a pomohly tak k vývoji nových léků. Ipilimumab (anti-CTLA-4 protilátka) a vemurafenib (selektivní BRAF inhibitor) dokázaly v randomizovaných studiích ve srovnání s chemoterapií prodloužit celkové přežití. Tyto léky se brzy stanou novým standardem v léčbě pacientů s pokročilým melanomem. K dalším velmi nadějným preparátům z oblasti cílené léčby patří dabrafenib (selektivní BRAF inhibitor) a trametinib (MEK inhibitor)., Malignant melanoma is the most aggressive type of skin cancer. The incidence of melanoma is increasing faster than most other cancers and affects a high proportion of younger adults. The standard treatment with chemotherapy or biochemotherapy has not been able to significantly improve survival. The recent advances in immunology and molecular biology of melanoma have discovered several potencial therapeutic targets and helped to develop new promising drugs. Ipilimumab (anti-CTLA-4 antibody) and vemurafenib (the selective BRAF inhibitor) have demonstrated improved overall survival compared with chemotherapy in randomized trials. These agents will soon represent new standard of treatment in patients with advanced melanoma. Dabrafenib (the selective BRAF inhibitor) and trametinib (the MEK inhibitor) are another very promising targeted drugs., Radek Lakomý, Alexandr Poprach, Renata Koukalová, and Literatura
The Purpose of the study: define the indications and contraindications to sphincterpreserving operation in lowerampullar cancer of rectum. The Materials and methods: In coloproctological branch of National Oncological Scientific centre (NOSC) in 20052009 years 142 patients were performed radical operations, 64 (45,1%) patients were performed sphincterpreserving operations abdominoanal resection of rectum (AARR), medium age of patients 59,8 years, beside 78 (54,9%) patients were performed abdomeno perineal extirpation of rectum (APER), medium age 54,2 years. The Results: Studied results of the morphological research of removed preparation by histological structure of tumors and by form of the growing, depending on locations of the tumors on toothed line. The remote postoperative results studied beside 51 (79,7%) patient with AARR and beside 63 (80,1%) patients with APER. The Findings: sphincterpreserving operations (SPO) of the rectum can be the operation of the choice in treatment of high differentiated adenocarcinoma (HDA) and medium differentiated adenocarcinoma (MDA) in stages T23 in localization of the lower pole of tumors, not below 1 centimeter of toothed line (TL) and carries combined character, in location of the lower edge of tumors on toothed line in patients with HDA MDA in 4% and 2,2% cases are shown that completing intrasphincternal resections of rectum, in connection with particular aggressiveness LDA question about choice of the method of the treatment under their localizations directly on TL must be solved in favour of complete APER, in exophytic tumor located onto and above TL is indication for sphincterpreserving operation in type of AARR, indices recurrencefree and not metastatic period, oneyear deathrate, threeyear survivability after SPO at inferior ampular cancer of rectum has not an essential distinction from results after APER., A.

The Material of the study has formed 78 sick, found on stationary treatment in Republican Scientific Centre Coloproktologii since 1992 on 2010. As it is seen, from table, from 78 sick mans was 58(74,3%), womans 20(25,7%). 19(24,3), sick were at age from 15 before 20 years, 49(60,2%) at age from 21 before 40 years and 13 (16,6%) sick from 41 before 60 years. The Main complaint sick at arrival were a stubborn constipations, which noted beside 70 (89,7%) sick, including absence of the independent chair existed beside 55(70,5%), but beside 54(69,2%) sick were noted periodic stomachache, growing on measure of the absence of the chair. The Ballooned belly existed beside all 78 (100%) sick moreover beside 20(25,6%) of them flatulence was constant. The Sickness and retching existed beside 24(30,7%), weakness, reduction to capacity to work beside 52(66,6%), increasing of the temperature of the body beside 10(12,8%), paradoxical diarrhoeas beside 6(7,6%) sick. Endoskopicheskiy method (rectoromonoscopy, colonoscopy) turned out to be else less informations 51,8% coincidences of the diagnosis. So we biopsy on Svensonu executed beside all sick, entered with suspicion on disease Girshprunga. In our observations from 78 sick beside 42(53,8,1%) were aboveanalni, beside 20(25,6%) sick rectalis, beside 13(16,6%)rectosigmoideys , beside 2(2,5%) leftside and beside 1(1,2%) sick subtotalis form hipoganglios. At biopsies on Svensonu on observations, from 78 sick, beside 44(56,4%) is revealled hipoganglios, but beside 35(44,8%) аganglios rectum. As can be seen from presented tables, from 78 sick beside 68(87,2%) us is executed onemoments radical operation, 10(12,8%) sick is as far as possible made resection hipoor aganglionarnaya of the zone, decompensate part of the large intestine and is formed colostomy. In all events at operations. The Remote results executed radical operation on cause disease Girshprunga traced from 1 before 10 years beside 57(73%) sick. The Results of the surgical treatment were valued on scale Vezika: good, satisfactory and unsatisfactory. In our observations beside 46(80,7%) sick results came in well, beside 10(17,5%) satisfactory and beside 1(1,8%) sick was an unsatisfactory result., Mirzahmedov M. M., Ahmedov M. A., Sapaev D.

Importance: Treatment of hepatocellular carcinoma remains a topical issue of Clinical Oncology. More than 80% of cases hepatocellular carcinoma develops in the presence of liver cirrhosis. These patients are doomed, many clinics they held only symptomatic treatment and life expectancy of patients is not more than 6 months. The main reason for the refusal of surgeons and Chemotherapeutists of treatment is associated cirrhosis. Purpose: To improve results of surgical treatment of liver cancer developed on cirrhosis Materials and methods: We analyzed the immediate results of treatment of 12 patients with hepatocellular carcinoma developed on a background of liver cirrhosis. From the large size of the tumor and associated liver cirrhosis, these patients the first stage of oil produced by hepatic artery chemoembolization of the affected lobe of the liver tumor. After 2 3 weeks performed liver resection. Results: After analyzing the results, we concluded: chemoembolization reduces tumor volume and weight, increases the physiological regeneration of hepatocytes unaffected tumor fraction, improves functional performance of the liver and does not affect the frequency and severity of postoperative complications., Juraev M.D., Nematov O.N., Yusupbekov A.A., and Literatura
Aim of investigation: to study immediate and remote results of standard and extended lymphodissection in patients with rectal cancer. Material and methods: 132 patients with rectal cancer were performed radical surgery with lymphodissection in D2 and D3 volume according to a height of tumor location. In immediate postoperated period there were noted complications in 4 patients that made up 3,03%. Observation time was 5 years. Tumor recurrence was reported in 5 patients (3,8%). In remote period metastases were revealed in 8 patients (6,6%). 5year total survival rate was 78,5±4,2% at stage II. 5year total survival rate was 56,4±3,7% at stage III. Comparing the results of standard and extended lymphodissection it was noted statistically authentic increase of 5 year survival rate in patients at stage III. Obtained data allow to come to the conclusion about reasonability of performance of different variants of lymphodissection for patients with rectal cancer at stages II and III., Navruzov S.

To improve the results of radiotherapy for cervical cancer used local and systemic radiomodification drugs. Materials and methods: 1984 patients with locally advanced cervical cancer (2b 3a stage), which at one stage of complex treatment by a course indoarterial of regional longterm polychemotherapy (EARDPHT) mode: methotrexate 50 mg/m2, the first 12 hours, fluorouracil 1000 mg/m2, over the next 12 hours and cisplatin 100 mg/m2, for 48 hours, 2 stage surgical treatment in the volume expanding hysterectomy 3 type (modification of Wertheim Meigs). Results: The results of treatment of locally cervical cancer using VADRPHT, depending on the unilateral and bilateral tumor invasion in parametrial tissue showed that under unilateral lesion of parametrium results of treatment were higher than for the bilateral involvement of parametrium. Medical pathomorphosis in tumors of different severity was observed in 86.9% of patients, metastasis to regional lymph nodes were detected in 36% of operated patients, and also studied the degree of therapeutic pathomorphosis in lymph nodes. There was revealed that the complete regression of tumors, 5 year survival rate is 98%, whereas in tumor regression of more than 50% of the original volume 78.5%, with stabilization of tumor no more than 58.4%. Conclusion: The study of molecularbiological parameters of the tumor cells show the effectiveness of conducted neoadvent indoarterial chemotherapy and play an important role in further treatment and prediction of disease., Navruzova V.
