Penn researchers identify new target, develop new drug for cancer therapies

(University of Pennsylvania School of Medicine) Opening up a new pathway to fight cancer, researchers at the University of Pennsylvania have found a way to target an enzyme that is crucial to tumor growth while also blocking the mechanism that has made past attempts to target that enzyme resistant to treatment. Researchers were able to use this finding to develop a drug that successfully inhibits tumor growth of melanoma as well as pancreatic and colorectal cancer in mice.

Pancreatic ductal adenocarcinoma (PDAC) has a 5-year survival rate of only 8% and is estimated to be the second leading cause of cancer-related deaths by 2021. Prior convention held that screening for PDAC would not be beneficial; however, a deeper understanding of the carcinogenesis pathway supports a potential window of opportunity among the target population. Screening for PDAC is not a standard practice among the general population because of its low incidence. However, screening may be beneficial for individuals with familial history, chronic diseases with genetic predispositions, or inherited cancer syndromes, such a...

CONCLUSIONThe considered clinical and biological features, at MPN diagnosis, were not different in cases with SC and controls. During the course of the disease, three factors significantly and independently affected the risk of SC in these MPN patients: 1) patients with PV had a 77% higher risk than those with ET, 2) patients with MPN duration of more than 5 years had a twice higher risk than those with lower duration, 3) for the first time, we documented that in non-skin solid cancers, aspirin treatment reduced SC risk of 38%. Exposure to HU and other cytoreductive drugs was confirmed as a risk factor for non-melanoma ski...

Waldenström's Macroglobulinemia (WM) is an indolent lymphoma with heterogeneous clinical presentation and prolonged course. In this context, determining the overall disease and therapy burden in terms of complications and associated comorbidities is necessary. Of special interest is the occurrence of a second malignancy and transformation to high grade lymphoma, due to their impact on survival and quality of life but also on health resource use and follow up strategies. Several factors including immune dysfunction, genetic predisposition, environmental factors and treatment effects have been suggested as possible unde...

Conclusion: Lynch syndrome confers an increased risk for multiple cancers other than colorectal and endometrial cancer. The proportions of other cancers vary between different MMR genes, with highest frequency in MSH2-carriers. Gender and age also affect the tumour spectrum, demonstrating the importance of additional environmental and constitutional parameters in determining the predisposition for different cancer types.

AbstractPurposeFew large-scale studies have investigated sex differences in cancer survival and little is known about their temporal and age-related patterns.MethodsWe used cancer registry data for first primary cancers diagnosed between 1982 and 2015 in Victoria, Australia. Cases were followed until the end of 2015 through linkage to death registries. Differences in survival were assessed for 25 cancers using the Pohar-Perme estimator of net survival and the excess mortality rate ratio (EMRR) adjusting for age and year of diagnosis.ResultsFive-year net survival for all cancers combined was lower for men (47.1%; 95% CI 46....

Metastases are responsible for the majority of cancer-related deaths. Although genomic heterogeneity within primary tumors is associated with relapse, heterogeneity among treatment-naïve metastases has not been comprehensively assessed. We analyzed sequencing data for 76 untreated metastases from 20 patients and inferred cancer phylogenies for breast, colorectal, endometrial, gastric, lung, melanoma, pancreatic, and prostate cancers. We found that within individual patients, a large majority of driver gene mutations are common to all metastases. Further analysis revealed that the driver gene mutations that were not share...

Mutations in Tumor Protein P53 (p53) are expressed in a variety of human cancers such as cholangiocarcinoma, melanoma, colon cancer, rectal cancer, ovarian cancer, endometrial cancer, non-small cell lung cancer (NSCLC), glioblastoma, uterine cervical cancer, head and neck cancer, breast cancer, pancreatic cancer, and bladder cancer. The p53 protein is involved in determining whether DNA is repaired or the damaged cell undergoes apoptosis – thus acting as a tumor suppressor by regulating cell division. Mutations in the p53 protein can reduce or eliminate its tumor suppressor function or interfere with wild type p53 in...
