How DNA damage turns immune cells against cancer

(University of Pennsylvania School of Medicine) The delayed arrival of immune cells after cancer therapy is well documented and critical for responses to chemotherapy and radiation, yet the events underlying their induction remain poorly understood. Now, Penn researchers have discovered how DNA damage is a clarion call for the immune system.

AbstractPurposeThis observational study was designed to measure baseline energy parameters and body composition in early-stage breast cancer patients, and to follow changes during and after various modalities of treatment. This will provide information to aid in the development of individualized physical activity intervention strategies.MethodsPatients with newly diagnosed stage 0 –III breast cancer were enrolled into three cohorts: A (local therapy alone), B (endocrine therapy), or C (chemotherapy with or without endocrine therapy). At baseline, 6 months, and 12 months, subjects underwent a stationary bicy...

CONCLUSIONS: Compared to ADT alone, the early (within 120 days of beginning ADT) addition of taxane-based chemotherapy to ADT for hormone-sensitive prostate cancer probably prolongs both overall and disease-specific survival and delays disease progression. There may be an increase in toxicity with taxane-based chemotherapy in combination with ADT. There may also be a small, clinically unimportant improvement in quality of life at 12 months with taxane-based chemotherapy and ADT treatment. PMID: 30320443 [PubMed - as supplied by publisher]

The number of elderly people with advanced lung cancer is increasing globally owing to the aging population and advances in cancer therapy [1]. More than 50% of patients diagnosed with lung cancer are aged>65 years, which is the lower limit for defining “elderly” in epidemiologic researches [2]. Non-small-cell lung cancer (NSCLC) accounts for 85% of all cases of lung cancer among both the elderly [3] and the adults. Although platinum-combination regimens including newer agents are the standard first-line chemotherapy for most patients with adva nced NSCLC, their use in elderly patients remains controversial [4].

Authors: Schanz M, Schricker S, Pfister F, Alscher MD, Kimmel M Abstract Cancer patients often exhibit preexisting renal impairment and are simultaneously at risk for developing further kidney injury due to direct or indirect complications of oncological therapies. The nature of kidney injury is highly dependent on the therapy regimen used, and the spectrum of possible kidney stressors has widened as a result of the development of new therapeutic modalities such as molecular therapy or immunotherapy. Indirect renal complications are often due to volume depletion or other therapy-related side effects. Direct toxicit...

This article provides an update of data that help inform clinicians of the role anthracyclines should play in adjuvant breast cancer therapy. Two recently reported large randomized trials—the Anthracycline in Early Breast Cancer and Western German Study Plan B studies—compared a taxane and cyclophosphamide regimen with an anthracycline, taxane, and cyclophosphamide regimen. Although the studies had conflicting results, together these studies suggest that the benefit of adjuvant anthracycline therapy over a nonanthracycline taxane‐containing regimen is modest at best and may be primarily seen in patients with ...

Publication date: 1 January 2019Source: Colloids and Surfaces B: Biointerfaces, Volume 173Author(s): Zhe Zhang, Na Niu, Xi Gao, Fuqin Han, Zhijun Chen, Shujun Li, Jian LiAbstractHypoxia is the main characteristic of tumor microenvironment, and the one of the key factors that cause the drug resistance of cancer cells for chemotherapy. Anticancer drug such as DOX cannot react with sufficient oxygen to produce reactive oxygen species (ROS) in hypoxic environment, which affects the therapeutic efficiency of the drug. In this work, we constructed a multi-functional nano-carrier (named as FeSiAuO) containing Fe3O4, mesoporous Si...

ConclusionSolely regarding sensitivity of AUS, our study could show significant differences between biological subtypes of breast cancer with lower sensitivity in Luminal patients. While PPV was excellent, standing for a low overtreatment rate using AUS for clinical decision making, sensitivity was poor overall, comparable to the results of other studies.

In conclusion, NKG2D-based CAR-T cells have potent in vivo and in vitro anti-tumor activities against gastric cancer and could be a new paradigm for patients with gastric cancer, either used alone or combined with chemotherapy.

ConclusionsMembrane-penetrating peptide-alike mutant-TRAIL-Mu3 induced pancreatic cancer cell death more efficiently than TRAIL, and this effect was supposed to be mediated by the increased affinity to cell membrane, the up-regulation of DR5 and the enhancement of activated caspase.
