Hotel, restaurant and carpentry trades are among professions posing highest risks for cancer of the oesophagus

18.12.2008
A new study led by Spanish researchers has revealed that exposure to certain substances may increase the risk of cancer of the oesophagus. The hotel and restaurant trades, animal handling, mining and carpentry are some of the professions posing the highest risk.

Jesús Vioque, a researcher at the Miguel Hernández University in Alicante, is leading a cases and controls study looking into the relationship between occupations and three types of cancer – oesophageal, pancreatic and stomach. The article showing the link between certain professions and the risk of suffering cancer of the oesophagus is the first to have been published.

The study, which appears in the latest edition of the journal Occupational and
Environmental Medicine, analyses the two principle types of cancer of the oesophagus, which account for more than 90% of all cases – squamous cell cancer (70-75%) and adenocarcinoma (15-20%).

“The two major risk factors for this cancer are alcohol and tobacco, but there is an additional number (around 4%-5%) of cases associated with certain occupations,” Vioque tells SINC.

The research study, which was carried out in nine hospitals in Valencia and Alicante, involved analysing the cases of 185 men with recently-diagnosed cancer of the oesophagus (147 squamous cell cancer, 38 adenocarcinoma) and 285 healthy controls. All those who took part in the study filled in a questionnaire about their diet, profession and lifestyle. The results were adjusted to take into account factors such as age, educational level and alcohol and tobacco consumption.

For the squamous cell variety, a significant increase in risk was detected among those who worked in the hotel and restaurant trade, mining (stone cutters) and wood-working workshops. With the adenocarcinoma type, the risk rose among those working as carpenters or animal handlers. An increase was also detected among workers involved in construction and electricity, “although these were based upon a very small number of cases”.

The study revealed a significant risk of squamous cell cancer resulting from exposure to ionising radiation, and for adenocarcinoma from serious exposure to volatile sulphur and lead compounds. Exposure to other substances such as asbestos could also triple the overall risk of oesophageal cancer, depending upon the level of exposure.

“We are not suggesting that people should give up their jobs, but if they are working in a high-risk profession they should adopt all suitable protection measures (goggles, masks or special machines). This is about trying to educate these workers in order to reduce their alcohol and tobacco consumption, but also to ensure they make use of all appropriate safety measures,” says Vioque.

Figures in Spain

Oesophageal cancer represents between 1% and 2% of all cancers. It is the fourth most common tumour of the digestive tract, behind colon, rectal and stomach cancer. It is more common among men than women, and it tends to appear between the ages of 55 and 70, with low numbers of cases among people aged under 40. According to data from the Spanish Society of Medical Oncology (SEOM), Spain has a medium level of incidence of this cancer (approximately 8 men per 100,000 and 1 woman per 100,000) in comparison with the rest of Europe.

Spain reports an annual incidence of 1,500 men and 250 women with oesophageal cancer, with the disease appearing more frequently in the north than in the rest of the country (Basque Country, Asturias and Navarre).

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
