Cannabinoids as Anticancer Drugs.

Cannabinoids as Anticancer Drugs. Adv Pharmacol. 2017;80:397-436 Authors: Ramer R, Hinz B Abstract The endocannabinoid system encompassing cannabinoid receptors, endogenous receptor ligands (endocannabinoids), as well as enzymes conferring the synthesis and degradation of endocannabinoids has emerged as a considerable target for pharmacotherapeutical approaches of numerous diseases. Besides palliative effects of cannabinoids used in cancer treatment, phytocannabinoids, synthetic agonists, as well as substances that increase endogenous endocannabinoid levels have gained interest as potential agents for systemic cancer treatment. Accordingly, cannabinoid compounds have been reported to inhibit tumor growth and spreading in numerous rodent models. The underlying mechanisms include induction of apoptosis, autophagy, and cell cycle arrest in tumor cells as well as inhibition of tumor cell invasion and angiogenic features of endothelial cells. In addition, cannabinoids have been shown to suppress epithelial-to-mesenchymal transition, to enhance tumor immune surveillance, and to support chemotherapeutics' effects on drug-resistant cancer cells. However, unwanted side effects include psychoactivity and possibly pathogenic effects on liver health. Other cannabinoids such as the nonpsychoactive cannabidiol exert a comparatively good safety profile while exhibiting considerable anticancer properties. So far experience with anticarcinogenic effects of cannabinoids i...

Abstract Vertebral metastases of non-small cell lung cancer (NSCLC) are frequently diagnosed in the metastatic setting and are commonly identified in the thoracic vertebrae in patients. Treatment of NSCLC bone metastases, which are often multiple, is palliative, and the median survival times are 3 to 6 months. We have characterized spontaneous vertebral metastases in a brain metastases model of NSCLC and correlated these findings with epithelial-mesenchymal transition (EMT). Brain metastases were established in athymic nude mice following intracardiac injection of brain-seeking adenocarcinoma NSCLC cells. Thirty-n...

Conclusions The recent, first randomized clinical trial demonstrated overall and progression free survival benefits after SBRT to oligometastatic disease which supports prior retrospective case series (6). The spine is a common site of metastatic bone disease, and as high quality data continue to mature, along with completion of additional randomized clinical trials, it is expected that utility of SBRT to the spine will increase in the future. Spine SBRT is unique due to the requirement of sharp dose falloff to prevent serious neurologic morbidity. With recent advances in radiotherapy planning, robotic patient positionin...

In this study, to improve our understanding of the role of ATP1A1 in the malignant phenotype and pathogenesis of GSCs, we evaluated ATP1A1 expression in GBMs of different grades and in two primary GSC lines established from human GBM tissues. We evaluated the role of ATP1A1 in GSC growth, its interactions with Src, and the activation of the ERK1/2 and AKT pathways. Our results revealed that ATP1A1 acts as an oncogene in our GSC models and targeting ATP1A1/Src may suppress GSC proliferation and growth. Materials and Methods Cell Isolation and Culture Human brain GBM tissues were from pathologically confirmed surgical spe...

Abstract JM is a 32-year-old primagravida with polycystic ovary disease. She had extreme difficulty conceiving and was started on clomiphene 6 months ago by her fertility specialist. After doubling the dose on the sixth cycle, she successfully became pregnant. On her second prenatal visit at 12 weeks gestation, an ovarian cyst was detected. Ultrasound showed a complex ovarian mass with nodules on the bowel and abdominal wall. There was mild-to-moderate peritoneal fluid. Cytology showed adenocarcinoma of ovarian origin. Further workup demonstrated advanced stage III epithelial ovarian cancer. JM was referred to GYN...

Survival time improved significantly for peritoneal mesothelioma patients in Finland who underwent a combination of surgery and chemotherapy, according to a recently released study. The five-year survival rate was 66 percent. The median survival was 62 months. According to a smaller, previous study in Finland, the median survival without treatment was just four months after diagnosis. “Despite these advances in treatment…the majority of patients with malignant peritoneal mesothelioma receive only palliative care of systemic chemotherapy, leaving many eligible patients without the benefit of this more invasive...

CONCLUSION: Adriamycin Cisplatin Vincristine Cyclophosphamide (ADOC), Cyclophosphamide Adriamycin Cisplatin, and paclitaxel + carboplatin all are viable first-line palliative CT options for mTET and showed a comparable survival in Indian patients. The present study suggested that “responders” to first-line CT and those with Stage IVa disease might have a better survival than “nonresponders” and those with Stage IVb disease, respectively.

Doctors at the Princess Margaret Cancer Center in Toronto are studying the use of hypofractionated radiation to increase the effectiveness of immunotherapy for patients with mesothelioma. They are expected to launch soon a clinical trial that will add an immunotherapy combination to the high-dose radiation and aggressive surgery mix that has been so successful in Toronto. “There are a lot of questions that still need to be answered, but if I was a betting man, I’d lay odds on it [working well],” Dr. John Cho of the cancer center’s clinical research unit, told The Mesothelioma Center at Asbestos.com....

Dexamethasone-induced inhibition of miR-132 via methylation promotes TGF-β-driven progression of pancreatic cancer. Int J Oncol. 2018 Nov 01;: Authors: Abukiwan A, Nwaeburu CC, Bauer N, Zhao Z, Liu L, Gladkich J, Gross W, Benner A, Strobel O, Fellenberg J, Herr I Abstract Glucocorticoids (GCs) such as dexamethasone (DEX) are administered as cancer co‑treatment for palliative purposes due to their pro‑apoptotic effects in lymphoid cancer and limited side effects associated with cancer growth and chemotherapy. However, there is emerging evidence that GCs induce therapy resistance in most e...
