The current article reviews a novel approach in tumor therapy based on peptide hormon analogs of GnRH, Bombesin/GRP and Somatostatin as carrier substances for cytotoxic agents, thus aiming to achieve a higher concentration of the active compound in the vicinity of the tumor. This therapeutic concept should lead to an increased antitumoral efficacy and minimized side effects. Targeted therapy with cytotoxic analogs of GnRH, Bombesin/GRP and Somato-statin has been highly effective in preclinical tumor models of breast, endometrial, and ovarian cancer, although associated with only a low haematological toxicity. In the current studies cytotoxic hybrid molecules were significantly more potent than the chemotherapeutic agent alone. However, the expression of the respective target receptor on the tumor cells is a necessary requirement for an effective therapy, as blockade of tumoral receptors significantly decreased the efficacy of the cytotoxic hybrid molecules in vivo. The haematological toxicity of targeted chemotherapy was significantly less pronounced than the corresponding nondirect-ed therapy with a cytotoxic radical alone in all animal experiments. The rapid development of a resistance to targeted chemotherapy is unlikely, as the expression of MDR proteins after targeted therapy was not increased as compared to a corresponding non-targeted approach in all experiments. AN-152, one of the compounds investigated in this article has already entered clinical testing. Thus, AN-152 showed a good tolerability in a clinical phase I study for patients with GnRH-positive breast, ovarian, and endometrial cancer and is now tested for efficacy in a clinical phase II study","PeriodicalId":123656,"journal":{"name":"Tumordiagn u Ther","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115739944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Potenziell kurative Therapieansatze sind die Tumorresektion und in ausgewahlten Fallen die Lebertransplantation. Diese chirurgischen Verfahren kommen aber aufgrund des Tumorstadiums oder der Leberfunktion fur einen Grosteil der Patienten nicht infrage. Weitere nichtchirurgische Therapieverfahren wie Radiofrequenzthermo- und Kryoablation, Alkohol- oder Saureinjektionen, transarterielle Chemoembolisationen, Strahlentherapie und systemische Chemotherapie konnen einzeln oder in Kombination in den verschiedenen Stadien der Erkrankung eingesetzt werden, um eine Verlangerung des (rezidivfreien) Uberlebens und in wenigen Fallen auch eine Heilung zu erzielen. Hepatocellular carcinoma is one of the most common cancers worldwide. The incidence of this disease is also increasing in the Western world. Typically, HCC is diagnosed when patients have already reached an advanced stage of the disease and the prognosis is poor. Potentially curative treatment options include surgical resection or liver transplantation and can be offered to patients with adequate liver function and tumour stage. Other non-surgical treatment options such as radiofrequency ablation, cryoablation, ethanol or acetic acid injection, transarteriel chemoembolisation radiation therapy and systemic chemotherapy can be offered either alone or in combination to selected groups of patients. These treatments can improve (tumour-free) survival and in a few cases even cure the patient.","PeriodicalId":123656,"journal":{"name":"Tumordiagn u Ther","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132040105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 48-year-old man was admitted because of an intracardiac tumor originating from the left atrium detected by chance. The patient had no symptoms associated with heart failure or arrhythmias. Transesophageal echocardiography revealed a large tumor mass probably encompassing the pulmonary veins. Due to this obstruction, a surgical exstirpation of the tumor was tried under cardiopulmonary bypass. But a resection of the tumor was not possible because of its large extension with diffuse cardiac infiltration. The histological diagnosis was non-Hodgkin(cid:29)s lymphoma of B-cell origin. Further lymphomatous lesions were detected in the abdomen. Combined chemotherapy was startet with partial remission at first. But the patient experienced a sudden bilateral visual loss. The funduscopy showed papilledema, hemorrhages of various types, and a cherry-red macula in association with tumoral optic nerve involvement. The retinal vessels were markedly narrowed or obliterated. The lumbar puncture revealed marked pleocytosis. The patient received whole brain irradiation together with intrathecal chemotherapy. However, there was no improvement in vision due to optic nerve atrophy. 5 months after admission, the patient died. Thus, even large cardiac tumors are often asymptomatic and detected by chance. Acute bilateral blindness caused by non-Hodgkin(cid:29)s lymphoma is a very rare disorder.","PeriodicalId":123656,"journal":{"name":"Tumordiagn u Ther","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121617435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the development of novel cancer treatment regimens, microarrays will in the future be indispensable in the elucidation of tumor development and progression, in the detection and monitoring of tumor heterogeneity, and the identification of putative risk factors. Microarrays will furthermore help in the identification of novel, more specific molecular targets crucial in the development of primary tumors as well as in the process of metastasis. In addition, multiparallel analysis of thousands of genes in tissues treated with putative anticancer drugs, will lead to a better, genome-wide understanding of the drugs efficacy, specificity and potentially harmful side-effects. The hope is to come up in the future with more potent and more specific anticancer agents at increased speed and chemical diversity. Die Entwicklung miniaturisierter angeordneter Muster von beispielsweise Nukleinsauren („microarrays”), mit denen sich tausende von Genen auf einer Flache kleiner als ein Daumennagel reprasentieren lassen, kann als ein technischer Durchbruch angesehen werden, der sich mit der Einfuhrung der PCR vergleichen lasst. Fur die Entwicklung neuer Tumortherapien werden Microarrays in Zukunft unverzichtbar sein fur die Analyse von Tumorentstehung und -progression, fur die Bestimmung der Heterogenitat im Tumor und bei der Identifizierung moglicher Risikofaktoren. Weiterhin werden Microarrays hilfreich sein bei der Definition neuer, spezifischerer Zielmolekule, die sowohl bei der Enstehung von Primartumoren als auch Metastasen eine Rolle spielen. Daruber hinaus wird die multiparallele Analyse tausender von Genen in Tumorgewebe unter Behandlung mit moglichen antineoplastischen Substanzen zu einem besseren, genomweiten Verstandnis der Effizienz, Spezifitat und moglicher unerwunschter Nebenwirkungen dieser Substanzen fuhren.
