Envita’s Precision Cancer Care: 35-Fold Improvement in Response Rates

引用

Journal of Cancer Therapy 2024年第4期15卷 99-120页

New clinical approaches are imperative beyond the widely adopted National Comprehensive Cancer Network (NCCN) guidelines, utilized by prominent cancer institutions. Cancer is the leading cause of death among individuals younger than 85 years within the United States. Despite significant technological advances, including the expenditure of hundreds of billions, treatment outcomes and overall survival have not notably improved for most types of advanced cancer over the last several decades. Over the past 24 years, Envita medical Centers has pioneered a unique form of personalized treatment approach for late-stage and refractory cancer patients, introducing groundbreaking innovations in the field. Our integrated algorithm utilizes advanced genomics, transcriptomics, and highly tailored immunotherapy, resulting in remarkable outcome improvements. This study presents Envita’s innovative personalized treatment algorithms and examines the response outcomes of 199 late-stage cancer patients treated at Envita medical Centers over a two-year period. Compared to standard of care and palliative chemotherapy, Envita’s treatment demonstrated a remarkable 35-fold improvement in overall response rates (Figure 1). moreover, 88% of the patients, the majority presenting with Stage 3 or 4 cancer, experienced a 43-fold improvement in quality of life with minimal side effects, as compared to standard of care chemotherapy and palliative care. This revolutionary success is attributed to Envita’s personalized therapeutic algorithms, which incorporate customized immunotherapy. Envita’s precision care approach has also achieved a 100% better response rate compared to over 65 global chemotherapy clinical trials with more than 2700 patients. The results from this study suggest that a wider utilization of Envita’s personalized approach can significantly benefit patients with late-stage and refractory cancer.

THE GULF STREAm OFF THE EAST COAST OF THE UNITED STATES

引用

Chinese Journal of Oceanology and Limnology 1988年第4期6卷 334-342页

作者： john m. Bane, jr.(marine Sciences Program, University of North Carolina, USA) marine Sciences Program University of North Carolina USA

Current and temperature data from a one-year-long instrument deployment in the region just northeast of Cape Halteras have shown the oceanic variability to be intense and quite complex. Changes in the position of the Gulf Stream’s path were observed to occur following cold core Gulf Stream passages through the area. The lime between these changes was a few months. The Gulf Stream jel itself was seen to meander in a manner previously observed, as long as it was not undergoing a strong ring/stream interaction. Several isolated vortices progressed through the array, with the majority of them being in the submesoscale coherent vortex class. Two mid-depth, anticyclonic warm eddies progressed through the array. It is likely the two events were caused by two different transits of the same eddy. The deep waters below the main thermocline oscillated as topographic Rossby waves progressed through the array area.
