Phyllodes tumors of the breast: The British Columbia Cancer Agency experience.

PURPOSE: Phyllodes tumors of the breast are uncommon fibroepithelial lesions for which optimal management remains unclear. This retrospective population-based study reports treatment and outcomes for patients with phyllodes tumors and evaluates characteristics that influence outcome. MATERIALS AND METHODS: Data were analysed on 183 patients with newly diagnosed phyllodes tumors from 1999 to 2014. Five-year Kaplan-Meier local recurrence and survival were compared between cohorts with benign (n=83), borderline (n=50) and malignant phyllodes tumor (n=49) histology. RESULTS: Median (range) follow-up was 65 (0.5-197) months. Local excision was performed in 163 and mastectomy in 19 patients. Eleven patients with malignant phyllodes tumors received radiation therapy. Overall, local recurrence occurred in 8.7%, distant metastases in 4.4%, and cause specific deaths in 3.8%. Five-year Kaplan-Meier outcomes among women with benign, borderline, and malignant phyllodes tumors were: local recurrence 6% vs 9% vs 21%, P=0.131; overall survival 96% vs 100% vs 82%, P=0.002; and disease-free survival 94% vs 91% vs 67%, P<0.001. Five-year Kaplan-Meier local recurrence among women with negative vs close vs positive margins were 8% vs 6% vs 37%, P<0.001. Corresponding rates for intermediate vs pushing vs infiltrative borders were 6% vs 6% vs 33%, P=0.006. Positive margins and infiltrative tumor borders were associated with increased local recurrence (all P≤0.006), and the latter remained significant in exploratory analyses after adjusting for margin status and phyllodes tumor classification. CONCLUSIONS: Five-year outcomes among women with phyllodes tumors were comparable to those reported in the literature. Exploratory analysis has suggested that infiltrative tumor borders may be used in conjunction with margin status to assess local recurrence risk.

Coordination of radiologic and clinical care reduces the wait time to breast cancer diagnosis.

BACKGROUND: In 2009, a Rapid Access Breast Clinic (rabc) was opened at our urban hospital. Compared with the traditional system (ts), the navigated care through the clinic was associated with a significantly shorter time to surgical consultation. Since 2009, many radiology facilities have introduced facilitated-care pathways for patients with breast pathology. Our objective was to determine if that change in diagnostic imaging pathways had eliminated the advantage in time to care previously shown for the rabc. METHODS: All patients seen in the rabc and the office-based ts in November-December 2012 were included in the analysis. A retrospective chart review tabulated demographic, surgeon, pathology, and radiologic data, including time intervals to care for all patients. The results were compared with data from 2009. RESULTS: In 2012, time from presentation to surgical consultation was less for the rabc group than for the ts group (36 days vs. 73 days, p < 0.001) for both malignant (31 days vs. 55 days, p = 0.008) and benign diagnoses (43 days vs. 79 days, p < 0.001). Comparing the 2012 results with results from 2009, a decline in mean wait time was observed for the ts group (86 days vs. 73 days, p = 0.02). Compared with patients having investigations in the ts, rabc patients with cancer were more likely to undergo surgery within 60 days of presentation (33% vs. 15%, p = 0.04). CONCLUSIONS: The coordination of radiology and clinical care reduces wait times for diagnosis and surgery in breast cancer. To achieve recommended targets, we recommend implementation of more systematic coordination of care for a breast cancer diagnosis and of navigation to surgeons for patients needing surgical care.

Laparoscopy as a cause of a false-positive Meckel's scan.

A new cause of a false-positive result of a Meckel's scan is reported. An 11-year-old girl had a 3-week history of constant right lower quadrant pain that was initially managed by laparoscopic appendectomy. A repeated laparoscopy for persistent pain was nondiagnostic. A missed Meckel's diverticulum was considered as the cause of this pain, which prompted a Meckel scan. This scan revealed a periumbilical focus of activity that was interpreted as a Meckel's diverticulum attached to the anterior abdominal wall by a band. The laparotomy showed no Meckel's diverticulum. The false-positive result of the Meckel scan may be the result of inflammation from the periumbilical laparoscopic port site.
