RESUMO
Malignant phyllodes tumours (PTs) are aggressive neoplasms with high rates of local recurrence and distant metastasis. With no known effective chemotherapy and no approved targeted therapy in the setting of metastatic disease, prognosis is limited with an often-relapsing course of disease. We report a case of a woman in her late 30s with a diagnosis of recurrent metastatic malignant PT who was found to have acrometastases of the malignant PT to the right distal index and small digits. We emphasise the potential for atypical patterns of metastases in patients with malignant PT and the need to recognise acrometastasis as an unusual but morbid manifestation of disease. Given the high growth rate of malignant PTs, the lack of systemic treatment options, and the ensuing distress for patients, prompt diagnosis and early intervention is crucial.

ABSTRACT: The lung is the most common site of metastases in the case of phyllodes tumor of the breast followed by bone. However, pneumothorax as a presenting complaint in a patient of bilateral cavitating lung metastases from malignant phyllodes tumor of the breast has never been reported to our knowledge. We herein report a case of a 34-year-old female presenting with sudden onset of chest pain in already existing lung metastases who on imaging showed the development of bilateral pneumothorax. We should, therefore, be on the lookout for the potential development of spontaneous pneumothorax in such cases.

BACKGROUND: Phyllodes tumors (PTs) are well known for local recurrence and progression. Less than 10% of these tumors grow larger than 10 cm. Distant metastases have been reported in up to 22% of malignant PTs, with most metastases being discovered in the lungs. PTs of the breast rarely metastasize to the gastrointestinal tract, and reported cases are scarce. To date, a review of the English literature revealed only 3 cases, including our case, of PTs metastasis to stomach. CASE PRESENTATION: An 82-year-old female patient had 10-year-duration of palpable huge tumor on left breast which was in rapid growth in recent months. Total mastectomy of left breast was performed thereafter, and pathology diagnosis was malignant phyllodes tumor. Adjuvant radiotherapy was suggested while she declined out of personal reasons initially. For PTs recurred locally on left chest wall 2 months later, and excision of the recurrent PTs was performed. She, at length, completed adjuvant radiation therapy since then. Six months later, she was diagnosed of metastasis to stomach due to severe anemia with symptom of melena. Gastrostomy with tumor excision was performed for uncontrollable tumor bleeding. CONCLUSION: For PTs presenting as anemia without known etiologies, further studies are suggested to rule out possible gastrointestinal tract metastasis though such cases are extremely rare. Management of metastatic gastric tumor from PTs should be done on a case-to-case basis, surgical intervention may be needed if there is persistent active bleeding despite medical treatment. Adjuvant radiotherapy is recommended in borderline and malignant PTs with tumor-free margin < 1 cm and high-risk malignant tumors. Adjuvant chemotherapy or target therapy may be helpful for metastatic PTs. Molecular and genomic techniques may predict clinical outcomes of benign and borderline PTs more precisely.

Lung is the most common target organ for distant metastasis of phyllodes tumor (PT), where the metastatic tumors are mostly seen as nodules or masses. We report here a rare case in which pure ground-glass opacity (GGO) was observed on chest CT about 3 years after the initial treatment of breast PT. After the lung lobectomy, we histologically confirmed that it should be diagnosed as a metastasis of PT. GGO rarely shows on metastatic tumors, and no reports have been made on GGO thus far in connection with metastasis of PT. Thus, in case GGO was found on the CT of patients having a history of PT, we suggest to take possible distant-metastasis into consideration.

RATIONALE: Malignant phyllodes tumors of the breast are rare, and there are currently no guidelines and a large number of clinical trials to guide the treatment of recurrence tumor. Here we reported a case of radiotherapy with apatinib for the treatment of recurrent malignant phyllodes tumor of the breast. PATIENT CONCERNS: A 58-year-old patient with massive breast mass was admitted to our hospital. Two months after surgical treatment, the tumor recurred in the chest wall scar. DIAGNOSES: The histopathologic diagnoses was right breast malignant phyllodes tumor with chondrosarcomas and osteosarcomas in some areas. INTERVENTIONS: The patient was first treated with surgery. Malignant phyllodes tumor recurred in the chest wall two months after surgery and was treated with radiotherapy and apatinib. OUTCOMES: With surgery, radiotherapy and apatinib treatment, the patient still died within several months. LESSONS: Apatinib and radiotherapy failed to obtain good therapeutic effect in the recurrence of breast malignant phyllodes tumor in this case.

BACKGROUND: Phyllodes tumours represent less than 1% of all UK breast neoplasms. Histological features allow classification into benign, borderline or malignant, which has a significant impact on prognosis and recurrence. Currently, there is no consensus for the optimal surgical excision margin. This systematic review aims to provide a comparative summary of outcomes (local recurrence, metastasis and survival) for borderline and malignant phyllodes tumours resected with either ≥1cm or <1cm margins. METHODS: MEDLINE and Embase were systematically searched (1990 to July 2019), in line with PRISMA guidelines. Study quality was assessed using the Newcastle-Ottawa scale. RESULTS: Ten retrospective studies were included (Newcastle-Ottawa scale mean score: 5.6, range: 8-4). Nine reported local recurrence rates, four reported distant metastasis and four reported survival. Meta-analysis pooling demonstrated no statistically significant difference between <1cm and ≥1cm margins in terms of local recurrence rates (relative risk [RR] 1.43, 95% confidence interval [95% CI] 0.70 - 2.93; p=0.33, n=456), distant metastasis (RR 1.93, 95% CI 0.35 - 10.63; p=0.45, n=72) or mortality (RR 1.93, 95% CI 0.42 - 8.77; p=0.40, n=58) for borderline and malignant tumours. Additionally, two studies demonstrated no significant difference in local recurrence for borderline tumours excised with <0.1cm margins compared to ≥1cm. CONCLUSION: Current evidence suggests that margins <1cm may provide adequate tumour excision. This could enable breast conservation in patients with smaller breast-to-tumour volume ratios, with improved cosmetic outcomes and patient satisfaction. A prospective, multi-institutional trial would be appropriate to further elucidate the safety of smaller margins.

RATIONALE: Malignant phyllodes tumors are rare breast neoplasms that are associated with a 6.2% to 25% incidence rate of distant metastasis; the lung is the most common metastatic site. To date, there is no consensus regarding the treatment of metastatic malignant phyllodes breast tumors. PATIENT CONCERN: A 48-year-old woman was admitted into the breast clinic for a rapidly growing right breast tumor that was first noticed 1 month prior. DIAGNOSIS: Core needle biopsy revealed a malignant phyllodes tumor. A chest computed tomography and positron emission tomography/CT showed metastatic lymph nodes that appeared to have spread to the right axilla, as well as multiple solitary pulmonary nodules in the right lung. Fine needle aspiration on the axillary lymph node confirmed metastasis. INTERVENTIONS: A right mastectomy with axillary lymph node dissection was conducted and a thoracoabdominal flap and a split thickness skin graft were performed for the skin defect. Palliative chemotherapy with doxorubicin plus ifosfamide was performed. OUTCOMES: An examination conducted 3 years postsurgery showed no signs of recurrence, and the patient's overall health status was satisfactory. LESSONS: As standard treatment guidelines for metastatic malignant phyllodes tumors are lacking, we opted for the aforementioned aggressive treatments that resulted in complete remission of the lung metastasis. Therefore, aggressive treatment, whenever possible, is warranted.

BACKGROUND: Phyllodes tumors (PTs) of the breast are uncommon fibroepithelial neoplasms. Most behave in a benign fashion but they also have the potential to recur locally or to metastasize. METHODS: In the current study involving 290 PTs (181 benign, 76 borderline, and 33 malignant) from three hospitals over an 11-year period, we assessed the relationship between histologic parameters (including histologic features affecting grade and surgical margin status), postoperative adjuvant treatment, and local recurrences and distant metastases. RESULTS: An involved surgical margin was the only factor associated with increased risk of local recurrences (hazard ratio [HR] 4.673, p = 0.003), but not for distant metastases. For local recurrences, a wider margin did not confer additional benefits. None of the histologic factors were predictive for local recurrences. In contrast, distant metastases were correlated with histologic parameters, particularly an infiltrative border (HR 10.935, p = 0.012) and the presence of necrosis (HR 15.311, p = 0.007). In this series, all local recurrences were found in patients without radiotherapy, regardless of surgical margin status. CONCLUSION: A negative surgical margin is mandatory for the effective local control of PT recurrence, and a minimal margin clearance may be sufficient. For distant metastases, the inherent characteristics of PTs are important, thus it may be prudent to evaluate additional histologic features, including necrosis, for patients' prognostication.

We present a rare and interesting case of a 35-year-old woman who initially underwent an uneventful wide excision for a 13 cm left benign phyllodes tumour. She then noted a slowly growing left thyroid nodule 8 months postsurgery which on thyroidectomy 4 years later was shown to be a 6.9cm isolated thyroid metastasis from the phyllodes tumour. As this may be the first reported such case in the literature, implications on histological classification, predictive factors for disease progression, mechanisms of metastasis, and evaluation, management and surveillance of benign phyllodes tumours and thyroid nodule/s with a history of phyllodes tumour can thus be significantly impacted.

BACKGROUND: This study aimed to assess their characteristics and clinical course of each histologic type of the behavior of phyllodes tumor (PT). METHODS: We retrospectively reviewed 124 patients with PTs who underwent surgical treatment from 2003 to 2011. PTs were classified as benign, borderline, and malignant using surgical specimens. The clinicopathological characteristics according to solitary and multiple lesions on ipsilateral breast and histological change after local recurrence were examined. RESULTS: The median patient age was 42 years (range 12-72 years). The final pathologic diagnosis was benign PTs in 95 patients (76.6%), borderline PTs in 21 (16.9%), and malignant PTs in 8 (6.5%). The size of benign PTs [median 4.2 cm (range 1-21 cm)] was significantly smaller than that of malignant PTs [median 11.3 cm (range 6-27 cm)] (p < 0.001). Eight of the 95 benign PTs (8.4%) had multiple lesions, while all malignant PTs had solitary lesion. With a median follow-up period of 45 months, five patients with malignant PTs (62.5%) developed distant metastases while 13 patients with benign PTs (13.5%) and 6 patients with borderline PTs (28.6%) had local recurrence only without malignant transition. The median overall survival period of those with malignant PTs was 22.5 months (range 5-109 months). CONCLUSIONS: Histologically benign and borderline PTs had a good prognosis without malignant transition even after developing repeat recurrence in contrast with malignant PTs that might be a solitary lesion.

AIMS: Phyllodes tumour (PT) is an uncommon fibroepithelial tumour of the breast. It has a spectrum of aggressiveness in biological behaviour with chance of local recurrence and, occasionally, metastasis. METHODS: A 15-year retrospective review from a multicentre database in Hong Kong was performed. RESULTS: Clinical and pathological records of 465 patients with 469 PTs between 1998 and 2014 were reviewed. Median age of occurrence was 44 years (range 12-86 years). 281 (59.9%) PTs were benign, 124 (26.4%) were borderline and 64 (13.6%) were malignant. About half of all PTs (239, 51.5%) were between 2 and 5 cm while another 186 (40.1%) were >5 cm in size. Most PT (84.6%) were radiologically benign. Breast-conserving surgery (BCS) was feasible in 384 (82%) patients, whereas 84 (18%) patients had mastectomy. Multivariate analysis found that positive surgical margin (P<0.001) and BCS (P<0.001) were the only significant risk factors for local recurrence, while large tumour size (P=0.008) and malignant PT histotype (P<0.001) were the only significant risk factors for metastasis. Long-term prognosis of benign and borderline PT was excellent. After median follow-up interval of 85 months (range 12-180 months), the disease-specific survival of benign, borderline and malignant PT were 99.6%, 100% and 90.6%, respectively. CONCLUSIONS: Local recurrence of PTs occurs irrespective of the tumour grade. Surgical margin is the only amendable factor to reduce the chance of recurrence.

BACKGROUND: Malignant phyllodes tumor (PT) is a rare fibro epithelial neoplasm of the breast, which is poor prognosis due to high risk of recurrence and distant metastasis. METHODS: We report a case of malignant PT. It had recurred locally five times, and the sixth relapse was occurred 54 months after first diagnosis, presenting a huge pelvic mass (14âcm × 11âcm) by CT scan. Histopathological examination has demonstrated a metastatic phyllodes tumor. After postoperative chemotherapy treatment, a longer survival has been achieved, which is more than 72 months. RESULTS: Our case report describes a breast PT with several local recurrences and a rare metastasis (pelvic cavity), but long-term overall survival was achieved after surgery and chemotherapy. CONCLUSION: We conclude that trustworthy prognosticators that identify patients with excessive potential of aggressive clinical course should be explored. Moreover, proper treatment could prolong overall survival of metastatic PT patients.

The aim of this study was to elucidate the clinicopathological and prognostic significance of the expressions of insulin-like growth factor II mRNA-binding protein-3 (IMP3) and epidermal growth factor receptor (EGFR) in phyllodes tumors (PTs). Immunohistochemical staining for IMP3 and EGFR was performed in 130 cases of primary PTs (83 benign, 28 borderline, 19 malignant), 34 recurrent/metastatic PTs, and 26 fibroadenomas (FAs). Among the primary tumors, a high expression of IMP3 was significantly more frequently present in malignant PTs (17/19, 89%) than in the FAs (0/26, 0%), benign PTs (0/83, 0%) and borderline PTs (3/28, 11%). The recurrent and metastatic lesions of malignant PTs also showed high IMP3 expression (3/5 [60%] and 6/6 [100%], respectively). Most malignant PTs showed strong IMP3 expression at the interductal area or more diffusely, whereas weak and focal (low) expression of IMP3 was limited to the periductal area in FAs and benign PTs. EGFR overexpression was significantly correlated with tumor grade and high IMP3 expression. Overexpressions of IMP3 and EGFR were significantly associated with shorter periods of metastasis-free and disease-free survival. The results suggest that high expressions of IMP3 and EGFR with a characteristic staining pattern may be helpful for both identifying malignant PT and predicting the prognosis of these tumors.

BACKGROUND: Phyllodes tumors are rare biphasic tumors occur predominantly in middle aged women. Malignant phyllodes tumor in children is very rare. OBJECTIVE: To report a case of malignant phyllodes tumor in a pre-menarchal girl. METHODS: H&E slides of the case were reviewed and follow up was obtained. RESULTS: The patient was 11-year-old girl who noticed a lump in her right breast 1 year back which grew rapidly in size. Wide local excision of the mass was done and histopathology revealed a malignant phyllodes tumor. Patient underwent mastectomy one month later due to recurrence. Two years later, she presented with dyspnea and chest pain. CT showed lung metastasis. The patient died of disease 1 year later due to widespread metastasis in liver and bone. CONCLUSION: We report a case of malignant phyllodes tumor in an 11-year-old girl, which behaved aggressively and patient died of disease due to widespread metastases 3 years after diagnosis.
