The immunomodulatory and antimetastatic activity of standardized aqueous mistletoe extract (sME) was evaluated in BALB/c-mice. Regular subcutaneous (s.c.) applications (three times per week for 14 consecutive days; 2, 20, 100 and 500 micrograms per injection and mouse) up-regulated thymocyte and peripheral blood leukocyte counts in tumor-bearing mice. Tumor weight and tumor volume were significantly down-regulated after application of sME doses greater than 20 micrograms per injection. To check the influence of sME treatment on growth of experimental metastases, RAW 117 H 10 lymphosarcoma cells and L-1 sarcoma cells were intravenously inoculated into BALB/c-mice to establish liver and lung colonization, respectively. sME was regularly administered starting 24 hours after tumor cell challenge. Organ colonization was investigated on day 14 after tumor cell inoculation and demonstrated statistically significant (p < 0.05) reductions of experimental liver and lung metastases for sME-treated mice.

Twenty patients with cytologically verified diagnosis of lymphosarcoma of the major salivary glands (15 with lymphosarcoma of the parotid gland and 5 with lymphosarcoma of the submandibular gland) were treated by radiotherapy. Twelve patients presented with stage I E, 7 with stage II E, and 1 with stage IV EO. Metastases in the cervical lymph nodes were diagnosed in 7 patients. Total focal doses for the primary tumor and metastases were 30-40 Gy during 3-4 weeks. The observation of 2-4 years showed that radiotherapy led to cure of 12 (60+/-15.4%) patients. No trends to relapses and generalization of the process were observed. No preventive exposure of the lymph discharge zones was carried out.

Variants of injection of LIO-1 lymphosarcoma cell suspension were studied. The number of animals with local metastases was higher after injection of LIO-1 cell suspension into the mouse paw sole. This method of tumor cell injection is suggested as the metastasizing model for experimental studies.

A 13-yr-old male African black-footed penguin (Spheniscus demersus) presented thrice over 7 mo with gastrointestinal obstruction secondary to cloacolithiasis. Clinical signs consistently resolved with cloacolith removal and supportive care. However, 10 mo after initial presentation, it presented with similar signs, plus significant weight loss. No cloacolith was found, and it subsequently died. Significant gross findings included bilateral cecal masses, colonic perforation, and marked secondary coelomitis, multifocal tan to pale hepatic nodules, and pale kidneys with miliary white foci. Histopathologic diagnoses were intestinal lymphosarcoma with hepatic and renal metastases, secondary intestinal rupture, and subacute severe bacterial coelomitis. To the authors' knowledge, this is the first full report of either cloacolithiasis or lymphosarcoma in a penguin.

Tumor-associated cell-free DNAs (cfDNAs) are found to play some important roles at different stages of tumor progression; they are involved in the transformation of normal cells and contribute to tumor migration and invasion. DNase I is considered a promising cancer cure, due to its ability to degrade cfDNAs. Previous studies using murine tumor models have proved the high anti-metastatic potential of DNase I. Later circulating cfDNAs, especially tandem repeats associated with short-interspersed nuclear elements (SINEs) and long-interspersed nuclear elements (LINEs), have been found to be the enzyme's main molecular targets. Here, using Lewis lung carcinoma, melanoma B16, and lymphosarcoma RLS40 murine tumor models, we reveal that tumor progression is accompanied by an increase in the level of SINE and LINEs in the pool of circulating cfDNAs. Treatment with DNase I decreased in the number and area of metastases by factor 3-10, and the size of the primary tumor node by factor 1.5-2, which correlated with 5- to 10-fold decreasing SINEs and LINEs. We demonstrated that SINEs and LINEs from cfDNA of tumor-bearing mice are able to penetrate human cells. The results show that SINEs and LINEs could be important players in metastasis, and this allows them to be considered as attractive new targets for anticancer therapy.
