[Local failures of nasopharynx carcinoma: Anatomoclinical aspects and therapeutic results].

PURPOSE: Retrospective analysis of clinical aspects and therapeutic results of nasopharynx cancer local failures.

PATIENTS AND

METHODS

Forty patients with local failure with or without nodal involvement of nasopharyngeal carcinoma were treated between 1993 and 2013. Reirradiation of nasopharynx was delivered at the dose of 60Gy. Platinum-based chemotherapy was indicated in case of locally advanced disease and/or associated nodal failure.

RESULTS

The mean age at diagnosis of primitive tumour was 41.9 years (26-67 years). The mean time of relapse occurrence was 31.7 months (6-104 months). Sixty five percent of failures were confined to the nasopharynx. Nodal failure was seen in 14 cases. Twenty-eight patients had chemotherapy. Twenty-five patients had reirradiation of nasopharynx. Mean follow-up was 98 months (12-191 months). Fourteen patients were still alive and in complete remission. Five-year survival was 40.7%. Xerostomia was the most frequent late toxicity. No haemorrhage was seen.

CONCLUSION

Reirradiation is the mainstay treatment of nasopharyngeal local failure. Late toxicity seems to decrease with novel techniques of reirradiation.
