Complexity of care processes in a radiation oncology service and its implications concerning the distribution of work and associated costs
ConclusionThe most expensive activities are those which are the most complex or consume the most resources. Knowledge of RVUs may be employed to analyse our activity and assess the possibility of increasing the efficiency of our service without prejudicing quality.
ConclusionsThe results of this study showed that lung volume changes were not a cause for concern in breast cancer patients. There are three reasons to support this conclusion. Lung volume changes and percentage reductions in LVP for each Gy increase of MLD and each percentage increase of V20 in each lobe were small; patients were asymptomatic during the follow-up period; and LVP showed partial improvements after 6 months.
ConclusionUsing robust optimization for skin flash in breast IMRT planning is feasible. Further investigation is warranted to confirm the clinical effectiveness of this novel approach.
ConclusionsThe exposure –response analysis suggested that intermittent 7-day veliparib 120 mg BID dosing in a 21-day cycle provided additional efficacy without meaningfully impacting the safety and tolerability when co-administered with carboplatin and paclitaxel in patients with BRCA-deficient breast cancer. A higher d ose of veliparib is unlikely to provide greater benefit in this combination in patients with BRCA-deficient recurrent or metastatic breast cancer.

Andrechek, Christopher Moraes, William J. MullerSummaryIntegrin receptors coordinate cell adhesion to the extracellular matrix (ECM) to facilitate many cellular processes during malignant transformation. Despite their pro-tumorigenic roles, therapies targeting integrins remain limited. Here, we provide genetic evidence supporting a functional redundancy between β1 and β3 integrin during breast cancer progression. Although ablation of β...

Singh, Sarah SpiegelAbstractTriple-negative breast cancer (TNBC) is very aggressive with high metastatic and mortality rates and unfortunately, except for chemotherapy, there are few therapeutic options. The bioactive sphingolipid metabolite sphingosine-1-phosphate (S1P) regulates numerous processes important for cancer progression, metastasis, and neuropathic pain. The pro-drug FTY720 (fingolimod, Gilenya) used to treat multiple sclerosis is phosphorylated in the body to a S1P mimic that binds to S1PRs, except ...

The photosensitizers were in the quenching state when loaded in the mesoporous MnO2 (mMnO2) nanoparticles and sealed by the aptamer on the particle surface. The aptamer can selectively recognize the specific membrane protein on the tumor cell and release the photosensit...
