Laryngeal cancer was retrospectively discussed on 213 patients who deceased or survived more than 5 years after the treatment was started in Aichi Cancer Center. From the observation over 5 years, it was found that an overwhelmingly large number of patients deceased due to other diseases than laryngeal cancer within 5 years and recurrence took place in only a few patients. Therefore, the patients surviving more than 5 years may fulfill their life when they were well controlled for their health so as not to suffer from other serious diseases. Based upon such a clinical evidence, we proposed that the percentage of the 5-year survivors should be deemed as a cure rate of laryngeal cancer in contrast with gastric cancer. Accordingly, we considered that the necessity of health-control system for aged people as coping with a social problem of drastic increase in their population will arise in the near future in Japan.
