Samenvatting

Exposure to irradiation or chemotherapy as well as prolonged exposure to risk factors, such as alcohol and tobacco, may induce a second primary carcinoma of the oesophagus. To estimate the potential risk of previous treatment regimens, we performed a case-control study. In the Tumour Registry of The Netherlands Cancer Institute, from 1955, 27 cases of squamous cell carcinoma of the oesophagus were identified following treatment for malignant lymphoma (n = 11), breast cancer (n = 8) and lung cancer (n = 8). The median interval was 6.6 years (range 1-16). Preferably 3 controls from the same tumour registry were matched to each case on the basis of sex, age, primary tumour, location of primary treatment (academic or general hospital), calendar year at diagnosis of primary tumour and duration of follow-up. Clinical data and details of treatment were obtained from the medical records. In patients who had smoked for more than 5 years, there was a 3.2-fold increased risk of oesophageal carcinoma (P = 0.04); for those with a regular alcohol intake the relative risk was 3.3 (P = 0.01). There was no significant relationship between irradiation of the mediastinum and subsequent risk for oesophageal cancer. The number of chemotherapy-treated patients was too small to calculate the relative risk associated with cytostatic drugs. In conclusion, oesophageal cancer as second primary cancer is extremely rare. Risk factors include the well known abuse of alcohol and tobacco. No significant relationship with previous mediastinal irradiation could be demonstrated.
