title: [Progressive systemic sclerosis (PSS) and cancer--increasing coincidence rate of cancer in 67 PSS patients].
abstract: The coincidence rate of cancer and PSS has been increasing according to reports from Nippon Byori Boken Shuho (Annual of Pathological Autopsy Cases in Japan), reaching 12.3% in the most recent report. Therefore we reviewed the histories of 67 PSS patients seen at our division over an 18-year period between 1974 and 1992, and found a high coincidence rate (14.6%) of cancer, reflecting the increasing tendency reported in the Nippon Byori Boken Shuho. The most frequent type of cancer was gastrointestinal cancer, including gastric and colon cancer and duodenal carcinoid. There were no significant differences in the clinical and laboratory findings between PSS patients with cancer and those without. Twenty-six of the 67 PSS patients died. Cancer was the cause of death in four, ranking second behind respiratory failure. The reason for the increasing coincidence rate of cancer and PSS is unclear at present. However, it is very important to discover cancer in PSS patients as early as possible, since it has a marked effect on prognosis.
