Summary

Introduction:
Phyllodes tumour is a breast tumour occurring very rarely. It accounts for only in 1% of all cases of breast tumour. The diagnosis of phyllodes tumours can be difficult in consideration of the small number of cases. Treatment of phyllodes tumours is always surgical.

Methods:
In 2004–2013, we operated on twelve female patients with phyllodes tumours out of the total number of 1564 surgeries for breast tumours (0.8%) at the Department of Surgery at Teaching Hospital in Pilsen. We evaluated the age, the biological behaviour of the tumour depending on the tumour size and duration, the distant metastases, therapy and survival.

Results:
The average age at the time of surgery was fifty years (26−84), the duration of disease to the surgical solution ranged from one month to ten years. Tumour size was in the range of two to twenty-nine centimetres, tumours measuring less than five centimetres were always benign. Tumour excision for benign phyllodes tumour was performed seven times. Malignant phyllodes tumour was diagnosed five times with mastectomy performed in each case, and the axilla was exenterated in three cases where nodes were benign in each of them. In one case, mastectomy was followed by radiotherapy because the tumour reached the edge of the resected part; the other patients were only monitored. In two patients, tumour spreading into the lungs was diagnosed at five to ten months after breast surgery. One patient with generalized disease died, the other ones live with no local recurrence of this disease. Median survival is fifty-two months; the disease-free interval is fifty months.

Conclusion:
The results show that if phyllodes tumour is diagnosed in time, it is almost exclusively benign. If the case history is longer and the tumour is growing, the likelihood of malignancy increases. Surgical treatment is also sufficient in the case of malignant forms. The breast surgery does not need to be supplemented with exenteration of axilla.

Key words:
breast – phyllodes tumour
