Experimental paramagnetic contrast of lung tumors with Pentamang 1.0 M

Objective: We have evaluated the image-enhancement properties of high-molar 1M solution of Manganese(II)- diethylentriaminpentaacetate (Pentamang 1M) as a paramagnetic contrast agent for detection of lung tumors, as well as tumor metastases, with Tl-weighted MRI in dogs.

Material and Methods: Pentamang 1M was obtained using original patented nanopowder technology from manganese dioxide or manganese carbonate and sodium diethylentriaminpentaacetate as described before (Beljanin e.a. 2008). Nine dogs were employed for the study, in all the lung tumor was suggested during routine veterinary clinical inspection and later on verified with ultrasonic study. MRI studies were carried out using low-field scanner (0,2 T Magetom Open machine, by Siemens Medical Ltd, Germany) in Tl- and T2-weighted modes before and 7-12 min after injection of pentamang 1M. The standard dose of pentamang 1M was as high as 1 ml of solution per 10 kg of BW. The results were reported by noninformed radiologist and quantified using enhancement index(IE), as IE=(Intensity of Tl-wMRIPentamang)/(Intensity of Tl- wMRIInitial).

Results: In all dogs the primary tumor as well as metastatic foci were significantly enhanced by injection of pentamang 1M. In particular the enhancement was forvarious locations of tumor masses as high as follows. In primary tumor the IE — 1,52 ± 0,09 ; in metastases in ribs IE = 1,29 ± 0,07; in paratracheal lymphatic metastases IE = 1,48 ± 0,11; in paraaortic mets the IE = 1,37 ± 0,07 ; in pleural metsIE = 1,33 ± 0,09. Nosignificant enhancement was seen in intact tissues, in particular in liver parenchyma, making evidence for stability of pentamng 1M. Nevertheless significant enhancement was observed inextumoral lung parenchyma, with IE= 1,23 ± 0,05, and also in myocardium, with IE = 1,15 ± 0,09.

Conclusion: The pentamang 1M provides significant paramagnetic enhancement of both primary lung tumors and metastatic involvement of lymph nodes, and hencefore pentamang IMis worth clinical testing as tumor imaging agent for chest MRI studies.

Blood serum apoptosis parameters changes at radiation therapy for malignant tumors

Objective: To determine the prognostic value of apoptosis markers (TNF- a, caspase-8 and p53) in the blood serum with the purpose to assess the efficacy of radiation therapy (RT) for malignant neoplasms.

Material and Methods: The study involved the patients with malignant tumors of different location. All the patients were administered RT according to the existing protocols, which depended on the tumor location and stage. The study design was developed in such a way that the final group included 31 patients (7 with breast tumors, 12 cervical tumors, 5 lung tumors, 7 head and neck tumors) who demonstrated diminishing of the tumor size by >30% and were performed all biochemical investigations by the end of RT. The controls were 14 healthy subjects. The material of the study was blood serum of the cancer patients obtained at the beginning and at the end of RT course. Solid phase immunoenzyme assay was used to determine tumor necrosis factor a (TNF-a), caspase-8 and p53 protein.

Results: The performed study showed that TNF- a is the most dynamic factor of the blood serum. Its significant increase was noted in all groups of the patients with various tumors. RT resulted in further growth of this parameter in the investigated groups. Evaluation of caspase-8 and p53 did not demonstrate any considerable regularities. Caspase-8 was not determined in 65% of the investigated samples of the blood serum; p53 — in 46 % of samples. In a number of patients with high p53 level this parameter did not change by the end of RT.

Conclusion: TNF- a is the most sensitive criterion for assessment of the tumor formation effects and RT results. Increase of TNF-a after RT allows to suggest that its effects are associated with activation of external apoptosis pathways, while determining caspase-8 and p53 in the blood serum with the purpose of RT efficacy assessment is poorly informative due to absence of a pronounced response to RT.

Key words: malignant tumors, radiation therapy, apoptosis, tumor necrosis factor a, caspase-8, protein p53.
