The patients were asked to complete a questionnaire on quality of life

The study involved 117 patients who had surgery for esophageal cancer in Sweden between 2001 and 2005 and survived at least five years. The patients were asked to complete a questionnaire on quality of life, a set of functions symptoms and answer measured . To get an idea of what was to maintain their quality of life as before surgery, the researchers had a group of 4,910 randomly selected people the same questions. The answers were then. As points on a 0-100 scale, where high scores for functions and low ones for symptoms were re new The analyzes were adjusted for age, sex and medical condition of health.

Worldwide Esophageal cancer is the eighth most common cancer. The prognosis is poor, and only 10 % of patients survive five years after diagnosis. The disease is often detected at a late stage after symptoms such as difficulty swallowing and weight loss. The only established curative treatment includes extensive surgery, often the abdomen, chest and neck. Approximately 30 % of patients survive the operation for at least five years. The purpose of the study was to determine whether the quality among five among five – year survivors of surgery for esophageal cancer on par with the average population.

In addition, the better understand the molecular basis of diseases have to’real optimistic that the new generation of improved drugs is just round the corner, ‘Professor Duncan said. And Last delivery systems join under the ‘nanomedicines ‘umbrella. Drug delivery schemes are required to many of the medications developing the progress of molecular biology exploit. Said: ‘ said: ‘The challenge is develop innovative instruments and to the therapeutic to the therapeutic to the correct location for action and to ensure that pharmacological activity of maintained for a reasonable period, soon to We make it is. ‘.

Using Looking ahead, Professor Duncan told in that nanomedicine research are expected for offer significant advances in the diagnosis and treating diseases. She said: It is still just the beginning the long run, Nanomedicines basic research is certainly to opportunities that arise of the develop about of stem cell research, tissue engineering research and miniaturization Real opportunities exist nanotechnology-sized schemes bioresponsive devices hug able. For diagnosing and be deliver drugs and systems, in tissue regeneration and repair , able promote no the need for chemotherapy alone. These ideas can sounds & Science Fiction today, however it would be too easily dismissed to foolishly. The risks and rewards to be addressed carefully in order yield useful and safe technologies, but it has been previously conducted, and will be again.
