Merkel cell carcinoma in France: a registries-based, comprehensive epidemiological survey
Summary
Merkel cell carcinoma (MCC) incidence increased over time in France, with higher rates in females. Prognosis for this rare skin cancer remains poor despite comparable incidence to other countries.
Area of Science:
- Oncology
- Epidemiology
- Dermatology
Background:
- Merkel cell carcinoma (MCC) is a rare neuroendocrine skin cancer.
- Limited epidemiological data exist for MCC, particularly in France.
- Analysis of French MCC trends was previously lacking.
Purpose of the Study:
- To analyze epidemiological trends of MCC in France.
- To investigate MCC incidence and mortality over time.
- To compare French MCC data with international statistics.
Main Methods:
- Utilized data from 11 French cancer registries (FRANCIM network) for MCC patients diagnosed 1998-2010.
- Focused analysis on 2006-2010 for comprehensive data availability.
- Calculated standardized incidence and analyzed survival rates.
Main Results:
- Reported 562 MCC cases between 1998-2010.
- Standardized incidence (2006-2010) was 0.26/100,000 (men) and 0.24/100,000 (women).
- Observed higher MCC frequency in females (56.9%) and poor 5-year survival (42%).
Conclusions:
- MCC incidence shows a clear increasing trend.
- French MCC incidence is comparable to international rates.
- Prognosis for MCC remains poor globally.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

01:27Introduction to Surveying, Plane Surveying and Geodetic Surveys
1.1K
Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...

1.7K
Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

01:19Errors and Mistakes in Surveying
758
Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of...

01:27Types of Surveys

Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...
