title: External radiotherapy for carcinoma of the eyelid: report of 850 cases treated.
abstract: OBJECTIVE
  We report a retrospective series of 850 patients treated by external irradiation for carcinoma of the eyelid at Institut Curie and we compare our results with other techniques: brachytherapy and surgery.
  
  
  METHODS
  Eight hundred fifty patients were treated by external radiotherapy for carcinoma of the eyelid. None of these patients have been previously treated. All the patients were classified according to the TNM classification of (UICC). We distinguished five histological types and five clinical groups according to the site of the skin tumor. Three modalities of external radiotherapy were used: contact therapy, conventional radiotherapy, and electrontherapy. We reviewed the clinical files of the 850 patients who went regularly at follow-up visits.
  
  
  RESULTS
  We report the 5-year survival results--alive with no evidence of disease: 72%; alive with progression: 2%; died from tumor progression: 0.5%; died from intercurrent disease: 19.5%; and lost to follow-up: 5%. The 5-year local control rate was 97.5%. We observed 45 failures--lymph node, metastatic, and local--and emphasize this last group by presenting the results of treatment of these local failures. We studied the complications of treatment: 2.3% of corneal complications, 2% of cataracts, and 1.4% of serious ocular complications.
  
  
  CONCLUSIONS
  Our results concerning local failures and loss of the eye are comparable to those reported for other techniques involving brachytherapy or surgery. Overall, external radiotherapy is a safe and effective treatment, as it ensures a high local control rate and provides perfectly satisfactory functional and esthetic results. It seemed particularly useful to report this series in that few publications are available on this subject that, nevertheless, constitutes a topical issue.
