Phyllodes tumour: an update of 40 cases
Annals of the Academy of Medicine, Singapore
|July 15, 1998
Summary
Phyllodes tumours are often misdiagnosed preoperatively, leading to simple excision. Recurrences in phyllodes tumour cases are uncommon but highlight the need for vigilant follow-up and wider excision if they occur.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Phyllodes tumours are rare breast neoplasms.
- Accurate preoperative diagnosis remains challenging.
- Treatment often involves surgical excision.
Purpose of the Study:
- To review the clinical characteristics and treatment outcomes of phyllodes tumours.
- To assess the diagnostic accuracy and recurrence rates.
- To evaluate the effectiveness of initial surgical management.
Main Methods:
- Retrospective analysis of 40 phyllodes tumour cases treated since 1985.
- Review of patient demographics, tumour size, and preoperative diagnoses.
- Analysis of histological classification and treatment modalities.
- Assessment of recurrence rates based on initial treatment.
Main Results:
- Mean age of presentation was 37.8 years; 90% were premenopausal.
- Mean tumour size was 52 mm; preoperative diagnosis was correct in only 5% of cases.
- Benign, intermediate, and malignant phyllodes tumours comprised 82.5%, 12.5%, and 5% respectively.
- Recurrence occurred in 10% of patients, all initially treated with simple excision.
Conclusions:
- Phyllodes tumours present diagnostic challenges, often leading to initial simple excision.
- While recurrences are infrequent, they necessitate careful follow-up.
- Wide excision is recommended for recurrent phyllodes tumours.
