MIDGE Technology for the Production of a Fourfold Gene-Modified, Allogenic Cell-Based Vaccine for Cancer Therapy

Gene modification of eukaryotic cells by electroporation is a widely used method to express selected genes in a defined cell population for various purposes, like gene correction or production of therapeutics. Here, we describe the generation of a cell-based tumor vaccine via fourfold transient gene modification of a human renal cell carcinoma (RCC) cell line for high expression of CD80, CD154, GM-CSF, and IL-7 by use of MIDGE® vectors. The two co-stimulatory molecules CD80 and CD154 are expressed at the cell surface, whereas the two cytokines GM-CSF and IL-7 are secreted yielding cells with enhanced immunological properties. These fourfold gene-modified cells have been used as a cell-based tumor vaccine for the treatment of RCC.

(American Society for Radiation Oncology) Treatment of renal cell carcinoma with stereotactic radiation therapy is as safe and effective for patients with one kidney as it is for those who have two, according to an analysis of the largest-ever, international dataset of solitary kidney patients to receive this emerging treatment. Findings will be presented in a news briefing today at 12 p.m. from the American Society for Radiation Oncology (ASTRO) Annual Meeting.

ConclusionsThe addition of standard doses of sunitinib or pazopanib to nivolumab resulted in a high incidence of high-grade toxicities limiting future development of either combination regimen. While there was no adverse impact on response and the OS outcome was notable, the findings suggest that the success of combination regimens based on immune checkpoint inhibitors and antiangiogenic drugs may be dependent on careful selection of the antiangiogenic component and dose.Trial registrationClinicaltrials.gov identifier:NCT01472081.

Conclusion: We demonstrated a strong association between the diagnoses of melanoma and RCC. These increased risks could not be attributed to either immune status or previous antineoplastic treatment.

CONCLUSIONS: Our research demonstrated the inhibitory function of miR-425 in ccRCA. Therefore, the miR-425/E2F6 axis was expected to be one of the targets of ccRCA targeted therapy. PMID: 30338798 [PubMed - in process]

Abstract In contrast to chemotherapy, treatment with immune checkpoint inhibitors occasionally results in an unconventional pattern of response. Besides an early partial or complete response or tumor progression, a so-called pseudoprogression, a "mixed response" or late responses can also be observed. Treatment beyond radiographically defined progression may therefore be appropriate in selected cases. For these treatment decisions, the clinical evaluation of the patient (performance status, symptoms, etc.), the "dynamics" of the underlying malignancy, and the availability of other tre...

A heightened understanding of hereditary renal cancer syndromes and their molecular basis has led to an increased awareness and recognition of these renal neoplasms by pathologists. Because a diagnosis of hereditary renal cell carcinoma has a profound impact on the patient and family members, when and how to raise such a suspicion via pathologic assessment has become an important yet very challenging task. This review discusses key clinicopathologic, immunohistochemical, and genetic characteristics of hereditary renal cancer syndromes, and important differential diagnostic challenges, emphasizing recent pathologic and molecular advances.
