Cancer survival statistics for patients and healthcare professionals – a tutorial of real-world data analysis
Monitoring the survival of cancer patients by using data collected by population-based cancer registries is an important component of cancer control. In this arrangement, the survival of patients often summarized using the survival clean, the survival of cancer if there is no other possible causes of death.
Although hygiene is the gold standard to compare survival between groups or from time to time, it is less relevant to understanding the real world patient prognosis anticipated. In this review, we will explain the statistical concepts targeted towards patients, physicians and health care professionals that the survival of cancer patients summarizes the assumption that there are other causes of death.
In particular, we explain the proper use, interpretation and assumptions behind the statistical methods for competing risks, loss of life expectancy for cancer and conditional survival. These concepts are relevant when producing statistics on risk communication between doctor and patient, the planning for the use of health resources, or other applications when consideration both cancerous and competing risk of death is required.
To reinforce the concepts, we used population-based data Swedish patients diagnosed with breast cancer, prostate, colon and chronic myeloid leukemia. We conclude that when choosing between steps Summary of survival are very important to characterize research purposes and to determine the nature of the hypothesis under investigation. Terminology and style of reporting options should be carefully tailored to the target audience and can range from a summary for readers of scientific publications specialist for interactive online tools intended for the layman.

TRP channel agonist orally declare stimulates the secretion of saliva and modify the saliva proteome
natural compounds that can stimulate the secretion of saliva interest in developing treatments for xerostomia, dry mouth perception, which affects between 10 and 30% of the adult and elderly population. Chemesthetic transient receptor potential (TRP) channel expressed in the mucosal surface of the mouth. TRPV1 agonist capsaicin and piperine have been shown to increase the flow of saliva when introduced into the oral cavity but the nature of the agonist sialogogic other TRP channels have not been investigated.
In this study we have determined a different effect on the flow of TRP channel agonists and protein composition of saliva. Rinse mouth with TRPV1 agonist nonivamide or menthol, a TRPM8 agonist, increased saliva around the mouth (WMS) flows and total protein secretion compared with unstimulated saliva, rinse the vehicle control or cinnamaldehyde, TRPA1 agonist.
Nonivamide also improve the flow of labial minor salivary glands but parotid saliva flow rate is not increased. TRP channel agonists influence on the composition and function of the salivary proteome multi-batch investigated using quantitative mass spectrometry method new to saliva proteomics.
Inter-personal and inter-rinse variation observed in the secreted proteomes and, using a new bioinformatics methods, inter-day variation is identified with some mouth rinses. Significant changes in the specific salivary proteins were identified after all mouth rinses. In the case of nonivamide, this change was associated with a functional shift in the WMS issued, especially representation over non-cystatins saliva and saliva were confirmed by immunoassay. This study provides new evidence of the impact of TRP channel agonist in the salivary proteome and the salivary secretion stimulation by channel TRPM8 agonist, which demonstrated that TRP channel agonists are potential candidates to develop a treatment for patients with xerostomia.
