Salsalate: a pleotropic anti-inflammatory drug in the treatment of diabetes, obesity, and metabolic diseases.

Type two Diabetes Mellitus (T2DM) is a rising epidemic. Available therapeutic strategies have provided glycaemic control via HbA1c reduction but fail to provide clinically meaningful reduction in microvascular and macrovascular (cardiac, renal, ophthalmological, and neurological) complications. Inflammation is strongly linked to the pathogenesis of T2DM. Underlying inflammatory mechanisms include oxidative stress, endoplasmic reticulum stress amyloid deposition in the pancreas, lipotoxicity, and glucotoxicity. Molecular signalling mechanisms in chronic inflammation linked to obesity and diabetes include JANK, NF-kB, and AMPK pathways. These activated pathways lead to a production of various inflammatory cytokines, such as Interleukin (IL-6), tumor necrosis factor (TNF)-alpha, and C-reactive protein (CRP), which create a chronic low-grade inflammation and ultimately dysregulation of glucose homeostasis in the liver, skeletal muscle, and smooth muscle. Anti-inflammatory agents are being tested as anti-diabetic agents such as the IL-1b antagonist, Anakinra, the IL-1b inhibitor, Canakinuma, the IL-6 antagonists such as Tocilizumab, Rapamycin (Everolimus), and the IKK-beta kinase inhibitor, Salsalate. Salsalate is a century old safe anti-inflammatory drug used in the treatment of arthritis. Long-term safety and efficacy of Salsalate in the treatment of T2DM have been evaluated, which showed improved fasting plasma glucose and reduced HbA1C levels as well as reduced pro-inflammatory markers in T2DM patients. Current publication summarizes the literature review of pathophysiology of role of inflammation in T2DM and clinical efficacy and safety of Salsalate in the treatment of T2DM.

Perioperative Levels of Troponin and BNP and the Outcome after Coronary Artery Bypass Grafting.

BACKGROUND: The independent predictive values of troponin I (cTnI) and B-type natriuretic peptide (BNP) after coronary artery bypass grafting (CABG) have been reported in several studies. However, adjustment only has been limited to preoperative risk factors. AIM: This study was conducted to assess the independent values of postoperative cTnI and BNP to predict the outcome after CABG with adjustment for preoperative risk estimates and postoperative complications and to report risk stratification gains, when considering the European System for Cardiac Operative Risk Evaluation (EuroSCORE) combined with postoperative biomarkers. METHODS: This retrospective cohort study included 282 consecutive patients undergoing CABG between January 2018 and December 2021. We evaluated the preoperative and postoperative cTnI and BNP, EuroSCORE, and postoperative complications. The composite endpoint was death or cardiac-related adverse events. RESULTS: The AUROC for postoperative cTnI was significantly higher than that of BNP (0.777 vs. 0.625, p = 0.041). The optimal cut-off values to predict the composite outcome were >4830 (pg/mL) and >6.95 (ng/mL) for BNP and cTnI, respectively. Adjustment for relevant and significant perioperative factors showed that postoperative BNP and cTnI had a high discriminatory power (C-index = 0.773 and 0.895, respectively) for predicting major adverse events. CONCLUSIONS: Postoperative BNP and cTnI are independent predictors of death or major adverse events, following CABG, and can add to the predictive power of EuroSCORE II.

First Cardiac Magnetic Resonance Experience in Bangladesh: A Case of Arrhythmogenic Right Ventricular Dysplasia.

Arrhythmogenic right ventricular dysplasia (ARVD) is a progressive degeneration and replacement of the right ventricular (RV) myocardial tissue by fat and fibrosis and produce clinical condition. Desmosome gene mutations are only the causative state for ARVD hereditary disorder. The arrhythmogenic right ventricular cardiomyopathy incidence is about 1/1000-5000. Mostly young people and athletes are bearing the clinical presentations include presyncope, syncope, ventricular tachycardias or ventricular fibrillation leading to cardiac arrest. We report about the first case of Cardiac magnetic resonance (CMR) imaging to diagnose a case Arrhythmogenic right ventricular dysplasia (ARVD) of a 34-year-old male from Savar, Dhaka, Bangladesh who was referred to cardiac emergency for the evaluation recurrent dizzy spells.

Chemical constituents of the aerial parts of Salvia judaica Boiss. from Jordan.

Investigation of the chemical constituents of Salvia judaica growing wild in Jordan led to the isolation and identification of 15 known compounds. These included: luteolin-3'-methyl ether (1), indole-3-carboxyaldehyde (2), p-hydroxybenzaldehyde (3), tricin (4), apigenin (5), methyl isoferuloyl-7-(3,4-dihydroxyphenyl) lactate (6), methyl rosmarinate (7), rosmarinic acid (8), salvigenin (9), ß-sitosterol (10), 3ß, 28-dihydroxyurs-12-ene (11), cirsilineol (12), 2,3-dihydroxyurs-12-en-28-oic acid (13), ß-sitosteryl glucoside (14), and tormentic acid (15). Compounds 6 and 7 exhibited strong radical scavenging and chelating activities as compared to α-tocopherol and ascorbic acid, compound 7 showed a 2-fold greater antioxidant activity as compared to compound 6. Furthermore, low doses of compounds 6 and 7 were able to inhibit the growth of leukemic (HL-60, Jurkat, K562 and CCRF-SB) and solid tumor cells (MCF-7, MDA-MB-231 and Caco-2). Compound 7 showed a ca. 3-4-fold stronger cytotoxicity against the tested cells as compared to compound 6.

Risk factors for prolonged mechanical ventilation after surgical repair of congenital heart disease. Experience from a single cardiac center.

OBJECTIVES: We studied these predictors at a single cardiac center. Methods: A retrospective cohort study was carried out after obtaining approval from the institutional review board. All patients (age, 0-14 years) who underwent  congenital heart disease (CHD)  surgery from January 2014 to June 2016 were included. Prolonged mechanical ventilation (PMV)  was defined as greater than 72 hours of ventilation. Results: A total of 257 patients were included, among whom 219 (85.2%) were intubated for greater than 72 hours and 38 (14.8%) were intubated for ≥72 hours. Age (29.9 versus 11.95 years), weight (9.6 versus 5.9 kg), cross-clamp time (CCT) (53.6 versus 71.8 min), cardiopulmonary bypass time (CBP) (80.98 versus 124.36 min), length of stay in the pediatric intensive care unit (PICU) (10.4 versus 27.2 days), infection (12.8% versus 42.1%), open sternum (0.9% versus 13.2%), re-intubation (19.2% versus 39.5%), pulmonary hypertension (10.9% versus 31.6%), and impaired heart function (10.1% versus 23.7%) were associated with PMV. In terms of Risk Adjustment in Congenital Heart Surgery (RACHS) classification, only patients with RACHS 4 (18.4%) were associated with the risk for PMV. Conclusions: Age, weight, CBP, CCT, pulmonary hypertension, impaired cardiac function, and sepsis are risk factors for PMV. These factors should be considered when deciding surgery and in providing PICU care.

Apoptosis and cell proliferation in short-term and long-term effects of radioiodine-131-induced kidney damage: an experimental and immunohistochemical study.

OBJECTIVE: Radioiodine-131 is a radionuclide that is used for therapeutic purposes in hyperthyroidism and thyroid cancer. The aim of this study was to evaluate apoptotosis and proliferative changes in radioiodine-related kidney damage. MATERIALS AND METHODS: Three groups (n=10/group) of rats were used as follows: the rats were in group 1 untreated, and the rats in groups 2 and 3 were treated once with oral radioiodine (111 MBq). The animals in group 2 were killed at the end of the seventh day and the rats in group 3 were killed at the end of the 10th week. The kidneys were removed and evaluated immunohistochemically. The presence of radioiodine in the kidneys was shown by the Na+/I-symporter antibody and proliferating cell nuclear antigen, Ki-67, caspase-3, caspase-8, caspase-9, and terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate nick end labeling assay were used to detect cell proliferation and apoptosis. RESULTS: Na+/I-symporter protein accumulation in the kidneys was observed to be significantly greater in group 2 than in group 3 (P<0.05). All the immunohistochemical analyses showed that cell proliferation and apoptosis began on the seventh day and peaked in the 10th week. The proliferating cell nuclear antigen, Ki-67, and caspase expressions and terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate nick end labeling values were all found to be statistically significantly increased in group 3 compared with the other groups (P<0.05). CONCLUSION: Radioiodine caused cell proliferation and apoptosis as shown by immunohistochemistry.

Internalization of a novel, huge lectin from Ibacus novemdentatus (slipper lobster) induces apoptosis of mammalian cancer cells.

An N-acetyl sugar-binding lectin (termed iNoL) displaying cytotoxic activity against human cancer cells was isolated from the slipper lobster Ibacus novemdentatus (family Scyllaridae). iNoL recognized monosaccharides containing N-acetyl group, and glycoproteins (e.g., BSM) containing oligosaccharides with N-acetyl sugar. iNoL was composed of five subunits (330, 260, 200, 140, and 30 kDa), which in turn consisted of 70-, 40-, and 30-kDa polypeptides held together by disulfide bonds. Electron microscopic observations and gel permeation chromatography indicated that iNoL was a huge (500-kDa) molecule and had a polygonal structure under physiological conditions. iNoL displayed cytotoxic (apoptotic) effects against human cancer cell lines MCF7 and T47D (breast), HeLa (ovarian), and Caco2 (colonic), through incorporation (internalization) into cells. The lectin was transported into lysosomes via endosomes. Its cytotoxic effect and incorporation into cells were inhibited by the co-presence of N-acetyl-D-mannosamine (ManNAc). Treatment of HeLa cells with iNoL resulted in DNA fragmentation and chromatin condensation, through activation of caspase-9 and -3. In summary, the novel crustacean lectin iNoL is incorporated into mammalian cancer cells through glycoconjugate interaction, and has cytotoxic (apoptotic) effects.

New isoflavones from Gynandriris sisyrinchium and their antioxidant and cytotoxic activities.

Chemical investigation of Gynandriris sisyrinchium (L.) Parl growing in Jordan resulted in the isolation and characterization of a total of twelve compounds two of which are reported here for the first time in nature. These new compounds included the isoflavones; 3'-methyl tenuifone (2) and gynandrinone (5). In addition, ten known compounds including; ß-sitosterol (1), 7,3'-dimethoxy-5,6,4'-trihydroxyisoflavone (3), iristectorigenin (4), hispidulin (6), galangustin (7), 6-hydroxybiochanin A (8), ursolic acid (9), ladanetin (10), 4'-O-methylgenistein (11) and ß-sitosterol glucoside (12) are also reported here for the first time from G. sisyrinchium. The isolated compounds were characterized by different spectroscopic methods including NMR (1D and 2D), UV, IR and MS (HRESIMS and EIMS). The antioxidant and cytotoxic activities of isoflavones 2, 3 and 5 were investigated. Compound 3 showed the highest antioxidant activity (IC50=17.3µg/mL), as compared to compounds 5 and 2 (IC50=26.7 and 51.7µg/mL, respectively). The cytotoxic activity against the human promyelocytic leukemia HL-60 cells revealed that compound 2 was the most active (40µM). The results indicate that the cytotoxicity of compound 2 is mediated by apoptosis.

Prophylactic role of α-lipoic acid and vitamin E against zinc oxide nanoparticles induced metabolic and immune disorders in rat's liver.

OBJECTIVES: Potential health hazard is associated with the wide use of nanoparticles. The prophylactic role of either α-lipoic acid (α-lip) or vitamin E (vit E) against the toxic effect of zinc oxide nano-particles (ZnO-NPs) induced metabolic disorder, inflammation and DNA damage in rat livers was studied. MATERIALS AND METHODS: ZnO-NPs were administered orally using two doses (600 mg and 1 g/kg body weight/day for 5 conscutive days). Some biomarkers of tissue damage, metabolic disorder, and DNA damage were investigated to explore the protective mechanisms of α-lip or vit E against ZnO-NPs induced hepatotoxicity. RESULTS: Co-administration of either α-lip (200 mg/kg body weight) or vit E (100 mg/kg body weight) daily for three weeks to ZnO-NPs intoxicated rats, significantly down-modulated the marked increase in serum ALT (marker of liver damage) and also serum glucose level (marker of metabolic disorder) as well as the pro-inflammatory biomarkers including nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), C-reactive protein (CRP), and immunoglobin G (IGg). Reduced glutathione level was decreased while caspase3 level was elevated in liver tissues of ZnO-NPs treated group compared with intoxicated one. Moreover histopathological examination of liver tissue supported the previous biochemical markers. Furthermore, ZnO-NPs induced hepatic oxidative DNA damage. CONCLUSIONS: Either α-lip or vit E proved to be hepatoprotective agents against ZnO-NPs toxicity because they ameliorated metabolic and immune disorders related to liver damage and modulated the previous measured parameters.

Sialyl-glycoconjugates in cholesterol-rich microdomains of P388 cells are the triggers for apoptosis induced by Rana catesbeiana oocyte ribonuclease.

SBL/RC-RNase was originally isolated from frog (Rana catesbeiana) oocytes and purified as a novel sialic acid-binding lectin (SBL) that displayed strong anti-cancer activity. SBL was later shown to be identical to a ribonuclease (RC-RNase) from oocytes of the same species. The administration of SBL/RC-RNase induced apoptosis (with nuclear condensation and DNA fragmentation) in mouse leukemia P388 cells but did not kill umbilical vein endothelial or fibroblast cells derived from normal tissues. The cytotoxic activity of SBL/RC-RNase was inhibited by desialylation of P388 cells and/or the co-presence of free bovine submaxillary mucin. FACS analysis showed that SBL/RC-RNase was incorporated into cells after attachment to cholesterol-rich microdomains. Addition of the cholesterol remover methyl-ß-cyclodextrin reduced SBL/RC-RNase-induced apoptosis. Apoptosis occurred through the caspase-3 pathway following activation of caspase-8 by SBL/RC-RNase. A heat shock cognate protein (Hsc70) and a heat shock protein (Hsp70) (each 70 kDa) on the cell membrane were shown to bind to SBL/RC-RNase by mass spectrometric and flow cytometric analyses. Quercetin, an inhibitor of Hsc70 and Hsp70, significantly reduced SBL/RC-RNase-induced apoptosis. Taken together, our findings suggest that sialyl-glycoconjugates present in cholesterol-rich microdomains form complexes with Hsc70 or Hsp70 that act as triggers for SBL/RC-RNase to induce apoptosis through a pathway involving the activation of caspase-3 and caspase-8.

Demographics and cell types of bronchial carcinoma of a tertiary care hospital in Bangladesh.

Geographical and socio-economic factors such as climate, culture, ethnic origin, diet and life style such as smoking have been noted to influence the occurrence of bronchial carcinoma. We conducted this study to document the frequency of various histological types of bronchial carcinoma and correlated it with their demographic characteristics. This descriptive study was carried out among admitted patient with the suspicion of Bronchial carcinoma from January 2010 to January 2011 in medicine units of Mymensingh Medical College Hospital, Mymensingh. Among those only 30 consecutive histopathologically &/or cytological confirmed cases of Bronchial carcinoma were included in the study. No age, gender, environmental or occupational limits were applied for the selection of patients. Patients already diagnosed by some other hospital presenting to our unit with complications were not included in the study. Age rang were 26-70 years. Majority of patients i.e. 63.33% (n=19) were found to be in their fourth and sixth decade of life. Males were 86.66% (n=26) as compared to females 13.44% (n=4) and male to female ratio were 6.5:1. The majority of the patients were belonged to urban areas 63.34% (n=19), while 36.66% (n=11) came from the Rural population. In this study smokers were 86.66% (n=26) and nonsmokers were 13.33% (n=4). In Occupational distribution farmers were 33.33% (n=10), service holders were 20% (n=6), businessman were 16.66% (n=5), all the female were house wife 13.33% (n=4). Specimens for histopathological study were collected by trans-thoracic needle aspiration under CT or ultrasono-guided. The results of cell types in histopathologically proven 30 Bronchial carcinoma patients were; 10(33.36%) adenocarcinoma, 7(23.33%) squamous cell carcinoma, 6(20%) small cell carcinoma, 4(13.33%) large cell carcinoma and 3(10%) non-small cell carcinoma.

Diagnostic evaluation of supraclavicular lymphadenopathy.

Patients presented with the supraclavicular lymphadenopathy in the medicine department have a strong suspicion of serious illness like tuberculosis, sarcoidosis, toxoplasmosis and malignancy of lymphnode, blood, lung, upper GIT, breast, ovary, testes, and other sites of body. This prospective type of observational study carried out in the indoor and out patient department of medicine of Mymensingh Medical College Hospital over a period of 6 month from April 2011 to September 2011 to diagnose the causes of supraclavicular lymphadenopathy. Patient of either sex, 18 years or above presented with supraclavicular lymphadenopathy were included. Biopsy or FNAC were done. The study showed that mean age of the patient of supraclavicular lymphadenopathy that finally diagnosed as malignant was 49.7 years and that of non malignant was 33.7 years. Male patient have suffered more (60%) from malignant disease than that of female patient (40%). Discrete, hard, non tender either fixed or non fixed supraclavicular lymphadenopathy was found malignant (18 of 18 cases, 100%) and discrete, firm, tender lymphnode were found non malignant (5 of 5 cases, 100%). Increased frequency (11 of 28, 39.3%) of granulomatous inflammation from the tuberculoid lymphadenitis were found among the patient undergone supraclavicular lymphnode biopsy. FNAC result was also of simillar type and finally it was found that frequency of tuberculosis (20 of 53, 37.7%) was highest and bronchial carcima was the second most frequent diagnosis (14 of 53, 26.4%). This study showed that supraclavicular lymphadenopathy is associated mostly with serious disease like tuberculosis and malignancy.

Fecal indicators and bacterial pathogens in bottled water from Dhaka, Bangladesh

Forty-six bottled water samples representing 16 brands from Dhaka, Bangladesh were tested for the numbers of total coliforms, fecal indicator bacteria (i.e., thermotolerant Escherichia coli and Enterococcus spp.) and potential bacterial pathogens (i.e., Aeromonas hydrophil, Pseudomonas aeruginos, Salmonella spp., and Shigella spp.). Among the 16 brands tested, 14 (86%), ten (63%) and seven (44%) were positive for total coliforms, E. coil and Enterococcus spp., respectively. Additionally, a further nine (56%), eight (50%), six (37%), and four (25%) brands were PCR positive for A. hydrophila lip, P. aeruginosa ETA, Salmonella spp. invA, and Shigella spp. ipaH genes, respectively. The numbers of bacterial pathogens in bottled water samples ranged from 28 ± 12 to 600 ± 45 (A. hydrophila lip gene), 180 ± 40 to 900 ± 200 (Salmonella spp. invA gene), 180 ± 40 to 1,300 ± 400 (P. aeruginosa ETA gene) genomic units per L of water. Shigella spp. ipaH gene was not quantifiable. Discrepancies were observed in terms of the occurrence of fecal indicators and bacterial pathogens. No correlations were observed between fecal indicators numbers and presence/absence of A. hydrophila lip (p = 0.245), Salmonella spp. invA (p = 0.433), Shigella spp. ipaH gene (p = 0.078), and P. aeruginosa ETA (p = 0.059) genes. Our results suggest that microbiological quality of bottled waters sold in Dhaka, Bangladesh is highly variable. To protect public health, stringent quality control is recommended for the bottled water industry in Bangladesh.

Changes in luteinizing hormone-containing gonadotrophs after moulting induced by fasting and zinc in laying hens (Gallus domesticus).

The purpose of the present study was to investigate egg production performance, immunohistochemical (IHC) identification, localization and morphological characterization of moulted hen's pars distalis luteinizing hormone (LH) gonadotrophs. This system has been validated for chicken LH by immunodetection of purified hormones on dot blots, western blotting and by specific labelling of cells on sagittal sections of chicken pituitaries. This study showed that egg production and egg weight increased significantly after zinc-induced moult when compared with fasting-induced moult. Luteinizing hormone-gonadotrophs are of numerous shapes and distributed throughout the adenohypophysis, with densely populated regions on the margins of pars distalis. Moulting of laying hens was associated with a significant increase in immunoreactive LH gonadotroph cell count and cell size, which peaked at the subsequent production stages. Zinc-induced moulting also caused a significant increase in LH gonadotroph cell size as compared with fasting-induced moulting. The nuclear size of LH-positive cells was distinct during decreased egg production. Our results validate the use of ovine LHbeta antibodies for the IHC localization of chicken LH gonadotrophs. This technology was further applied to the characterization of the shape and morphological changes of gonadotrophs as a function of the egg production status of the birds.

Long-term management of bilateral metastases of renal cell carcinoma to the choroid plexus.

BACKGROUND: Metastatic tumors to the brain presenting exclusively in the choroid plexus are exceedingly rare. These events are frequently associated with renal cell carcinoma (RCC), of which all reported cases have been solitary lesions. METHODS: The authors present the unusual case of a patient with metastatic RCC who developed bilateral tumors of the choroid plexus. These tumors, one of which was confirmed to be metastatic RCC by histologic analysis, were treated over a 5-year period with a combination of interventions, including surgical resection, stereotactic radiosurgery, and chemotherapy, in conjunction with continual radiological monitoring. FINDINGS: Follow-up over a 5-year period demonstrated good control of the patient's intracranial disease and very little neurologic sequelae. INTERPRETATION: This strategy was successful in keeping the patient in good health with minimal neurological symptoms, despite the bilateral nature of the disease and its generally poor prognosis.

Nitric oxide-releasing nonsteroidal anti-inflammatory drugs (NSAIDs) alter the kinetics of human colon cancer cell lines more effectively than traditional NSAIDs: implications for colon cancer chemoprevention.

Nitric oxide-releasing nonsteroidal anti-inflammatory drugs (NO-NSAIDs), consisting of a known nonsteroidal anti-inflammatory drug (NSAID) and a nitric oxide (NO)-releasing group, are reported safer than NSAIDS: To assess their potential in colon cancer chemoprevention, we studied in vitro the effect of NO-aspirin, NO-sulindac, and NO-ibuprofen on colonocyte kinetics. These three NO-NSAIDs reduced the growth of cultured HT-29 colon adenocarcinoma cells much more effectively than the corresponding NSAIDs; e.g., at 24 h, their IC(50) values were as follows: (a) aspirin, >5000 microM; (b) NO-aspirin, 1 microM; (c) sulindac, 750 microM; (d) NO-sulindac, 150 microM; (e) ibuprofen, >1000 microM; and (f) NO-ibuprofen, 42 microM. This effect was due to inhibition of proliferation and induction of apoptosis and perhaps to the induction of novel cell changes, characterized by extensive DNA degradation. NO-NSAIDs also blocked the G(0)-G(1) to S cell cycle transition. Their superior effectiveness compared with traditional NSAIDs, combined with their reported safety, makes them promising candidates for chemopreventive agents against colon cancer.

Determination of 1H relaxation times of water in human bone marrow by fat-suppressed turbo spin echo in comparison to MR spectroscopic methods.

Relaxation times of water were measured in human vertebral bodies by a fat-suppressed dual-echo turbo spin echo/turbo inversion recovery MRI sequence. Comparison was made with T1 and T2 values obtained by localized 1H-MR spectroscopy. The accuracy of the results and the diagnostic potential of the fast quantitative MRI technique were evaluated in 20 volunteers, 11 patients with osteoporosis, 6 patients with lymphoma, and 6 patients with bone marrow metastasis. No significant alterations of T1 and T2 relaxation times of water and fat were found in osteoporosis. With both methods, an increase in the T1 values of the water resonance by 16% was observed in lymphomas, which was highly significant (P < .001) in the MRS measurements, and an elevation by the same amount was obtained by the MRI sequence for the metastases (P = .040). A strong reduction of fat fraction was quantified by MRS in the tumorous cases. T2 of the water resonance increased by more than 30% (P < .003) in metastases. Water T2 values obtained by the MRI sequence showed systematic deviations from the MRS results, especially at short echo spacings.

[Superselective intra-arterial chemotherapy in therapy-refractory lymph node recurrences of breast carcinoma]. / Superselektive intraarterielle Chemotherapie bei therapierefraktären Lymphknotenrezidiven von Mammakarzinomen.

PURPOSE: To demonstrate a superselective intraarterial chemotherapy as a therapeutic alternative in the treatment of previously treated recurrent lymph node metastases in breast cancer. METHODS: 14 patients with recurrent lymph node metastases in cases of breast cancer were presented to be treated by intraarterial chemotherapy of 25 mg mitoxantrone/m2 over a period of 24 hours. In two patients with superclavicular lymph node involvement an intraarterial therapy could not be carried out because of a vascular connection to the anterior spinal artery. Involved lymph stations could be reached in superselective technique by side branches of the subclavian artery. Heparin coverage was given intravenously. Every patient had had surgery, radiation, systemic chemo- and hormonal therapy before and was now graded as inoperable. Therapy indication was given by local tumour-induced symptoms. RESULTS: In the 12 treated cases complete remission was seen in three, partial remission in 4, a steady state in two and a progressive disease in three. There were no complications or severe side effects. CONCLUSION: Intraarterial chemotherapy is an effective and well tolerated treatment in recurrent lymph node metastases in cases of breast cancer even if conventional therapies can no longer be used.

[Intra-arterial treatment of therapy-resistant residual tumors of the pelvis]. / Intraarterielle Behandlung von therapierefraktären Tumorrezidiven des Beckens.

PURPOSE: Evaluation of intraarterial cancer treatment in recurrent pelvic tumors, which were resistent to other treatment modalities. PATIENTS AND METHODS: Ninety-seven patients suffering from pelvic recurrences originating from bladder (n = 40), rectum (n = 19), cervix (n = 21) oder other organs (n = 17) were treated by intraarterial chemotherapy (111 times) or transcatheter embolisation (52 times). RESULTS: Less than 20% of our patients had remission of the tumor burden but tumor symptoms (especially pain and bleeding) could be controlled in 35 to 87% of the patients. The main complication was a muscle necrosis after intraarterial chemotherapy because of recurrent bladder cancer. CONCLUSION: Intraarterial cancertherapy is a useful procedure for symptomatic treatment of tumor symptoms especially in case of bleeding. Local tumor control can only be achived in a minority of the patients.
