Tumor To Tumor Metastasis

The tumor-to-tumor metastasis phenomenon remains fairly uncommon, with fewer than 100 cases described to present time. Virtually any tumor can be a donor or a recipient neoplasm. Nevertheless, renal carcinomas have been implicated as the most common malignant tumors to harbor metastasis, while lung and breast tumors are the most frequent donors. This article reports an extremely rare case of a breast cancer metastasis in a lung metastasis of clear cell type renal cell carcinoma that met all Campbell and coworkers’ tumor-to-tumor metastasis criteria. Additionally, we present the literature case reports of breast cancer metastasis in renal cell carcinomas and try to discuss the mechanisms underlying its occurrence. Since this phenomenon identification will impact the therapeutic strategy and it is not easily detected by image, the anatomopathological study of any and all suspicious lesions is of crucial importance. To the best of our knowledge, this is the first report of a metastasis inside a metastasis.

Gene Expression Levels

The most serious complication of breast cancer (BC), which affects life expectancy, is metastasis of the tumor. Metastasis is the cause of more than 80% of all breast cancer deaths. After surgical treatment and the use of adjuvant therapy, metastases occur in 8% 15% of cases. This indicates the need to develop markers for the prognosis of metastasis and clarify its mechanisms for the creation of anti-metastatic therapeutic agents. In this paper, we studied the association of LOX and uPAR gene expression with breast cancer metastasis in the lymph nodes. Gene expression was measured using real-time PCR in 40 paired samples (tumor-normal tissues). As a result of processing the measurements, the values of gene expression levels in the tumor tissue relative to normal were obtained. It is shown that the LOX gene is expressed in the tumor both lower and higher relative to the norm, and uPAR is expressed in most cases higher. In metastatic tumors, the frequency of expression increases above the norm for both LOX and uPAR genes. The association of expression of these genes with lymphatic metastasis was found: p = 0.01 and p = 0.02, for the LOX and uPAR genes, respectively. The relative risk (RR) was for the LOX gene RR = 1.9, 95% CI 1.2 3, p = 0.005, for uPAR RR = 3.6, 95% CI 1.2 10.9, p = 0.03. Thus, the data obtained contribute to understanding the mechanisms of metastasis and provide the basis for the development of new biomarkers. The LOX and uPAR genes may be candidates for predictive markers of breast cancer metastasis risk.

Membrane Type

The membrane-tethered membrane type 1–matrix metalloproteinase (MT1-MMP) mediates proteolysis-based invasive tumor growth. In this issue, Marchesin et al. (2015. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201506002) describe a tug-of-war mechanism regulating dynein and kinesin motors to drive endosome tubulation and MT1-MMP delivery to the surface of cancer cells, identifying a crucial regulatory axis for tumor metastasis.
