The Dawn of a New Age in Cancer Immunotherapy

It was over one hundred years ago that immunotherapy for cancer was first explored by Dr William Coley with the intratumoral injection of bacterial extracts that resulted in tumor regression in select cases. The emergence of surgical procedures, radiation therapy, and chemotherapy eventually became the mainstay of cancer therapies and relegated immune treatments as an unfulfilled pipedream. Nevertheless, it has been apparent that the immune system can play a role in tumor biology as evident by cases of spontaneous tumor regression and increased cancer incidence among immunosuppressed patients.

For years, cancer treatment was dominated by chemotherapy, radiation therapy, and stem cell transplantation. New insights into genetic characteristics of leukemic cells have initiated the development of the chimeric antigen receptor (CAR) T-cell therapy. This type of adoptive cell immunotherapy has been a breakthrough in the treatment of aggressive B-cell lymphoma and B-cell precursor acute lymphoblastic leukemia. In August 2018, the European Commission has approved the first CAR T-cell products – tisagenlecleucel (Kymriah®, Novartis) and axicabtagene ciloleucel (Yescarta®, Gilead) – for hematological n...

Conclusion: Childhood cancer survivors present with unique challenges for dental management because of dental anomalies caused by cancer therapy. Interprofessional collaborative care between the pediatric dentist and the oncologist during and after cancer therapy will enable best outcomes for the pediatric patient. In addition, dental professionals must be prepared to meet the unique needs of long-term cancer survivors because of the increasing survival rates of childhood cancers. PMID: 30559620 [PubMed]

One major challenge in the development of effective cancer therapies is a lack of universal, cancer specific markers in target cells. The current standard therapies rely on surgery, chemotherapy, and radiation therapy. Such procedures lead to a population of resistant cancer cells that makes further applications of chemotherapy/radiation therapy ineffective. Additionally, the systemic application of chemotherapy lacks specificity and has   off-target systemic effects that lead to adverse side effects. A considerable effort has been devoted to identifying and targeting specific extracellular cancer markers using antibo...

AbstractBackgroundThe interplay between the immune system and cancer cells has come to the forefront of cancer therapeutics, with novel immune blockade inhibitors being approved for the treatment of an increasing list of cancers. However, the majority of cancer patients still display or develop resistance to these promising drugs. It is possible that cancer stem cells (CSCs) are contributing to this therapeutic resistance. Although CSCs usually represent a small percentage of the total number of cancer cells, they are endowed with the ability of self-renewal and to produce differentiated progeny. Additionally, they have sh...

te; G Abstract Over the past few years, several preclinical studies have highlighted the value of CD73 (ecto-5'-nucleotidase) as a potential therapeutic target for cancer therapy. Indeed, the pharmacological blockade of CD73, via monoclonal antibodies or small molecules, has promise in counteracting cancer development, growth and spread. Synergistic combinations of anti-CD73 drugs with conventional cancer treatments (i.e., chemotherapy, radiation therapy, immunotherapy, targeted therapy) have increased therapeutic potential. In this review, we discuss the potential synergistic effects of CD73 blockers and conventi...

Abstract Neuroendocrine carcinoma of the cervix is an ultra-rare malignancy with a poor prognosis and limited treatment options. Checkpoint blockade immunotherapy has rapidly developed into an emerging standard of care for several common disease types. Interestingly, in preclinical and retrospective clinical data, radiation therapy has been demonstrated to synergize with checkpoint inhibitors. Here we report a patient with metastatic, chemotherapy-refractory neuroendocrine carcinoma who presented with partial bowel obstruction due to a large tumor burden. Genomic analysis demonstrated a high number of alterations ...

Authors: Suh DH, Kim M, Kim K, Kim HJ, Lee KH, Kim JW Abstract In 2016, 13 topics were selected as major research advances in gynecologic oncology. For ovarian cancer, study results supporting previous ones regarding surgical preventive strategies were reported. There were several targeted agents that showed comparable responses in phase III trials, including niraparib, cediranib, and nintedanib. On the contrary to our expectations, dose-dense weekly chemotherapy regimen failed to prove superior survival outcomes compared with conventional triweekly regimen. Single-agent non-platinum treatment to prolong platinum-f...

DISCUSSION: Immune-based cancer therapies are already revolutionising the management of several types of hitherto intractable cancer, while offering immense hope that the burden of personal suffering and community cost due to cancer will diminish appreciably over the coming decades. At least two immunotherapeutic approaches, checkpoint inhibition and cellular therapy with autologous ('self') chimeric antigen receptor T cells (CAR T cells), now show indisputable evidence of efficacy in several cancer types, and promise yet more rapid progress as they are refined and we learn to combine them with existing conventional therap...

For more nearly four decades, our research has focused on one challenge: improving the delivery and efficacy of anti-cancer therapies. Working on the hypothesis that the abnormal tumor microenvironment fuels tumor progression and treatment resistance, we developed an array of novel imaging technologies and animal models as well as mathematical models to unravel the complex biology of tumors. Using these tools, we demonstrated that the blood and lymphatic vasculature, fibroblasts, immune cells and the extracellular matrix associated with tumors are abnormal, which together create a hostile biochemical and physical tumor mic...
