Upstaging of Fibroepithelial Lesions: A Single-Institution Experience.

INTRODUCTION: Fibroepithelial lesions of the breast (FEL) are heterogeneous lesions ranging from fibroadenomas (FA) to phyllodes tumors (PT). FEL with cellular stroma are diagnostic challenges on core needle biopsy (CNB) as it is difficult to distinguish cellular FA from PT. The purpose of this study was to determine the features of FEL on CNB that may be predictive of PT, the upstage rate to PT after excision, and the outcomes of those who did not undergo excision. METHODS: Overall, 305 patients with FEL on CNB between 2009 and 2019 were identified from a prospectively maintained institutional database. Presentation, imaging, and pathology were evaluated. RESULTS: Mean age at diagnosis was 43.8 years. Pathology on CNB included 97 cases of FEL favoring FA, 19 cases of FEL favoring PT, 3 cases of FEL versus pseudoangiomatous stromal hyperplasia, and 186 cases of FEL not otherwise specified. Following CNB, 96 (31.5%) patients were observed, 158 (51.8%) patients had an excisional biopsy, 48 (15.7%) patients underwent segmental mastectomy, and 3 (1.0%) patients underwent a mastectomy. The upgrade rate from FEL on CNB to PT upon excision was 25.8%. PT on final pathology was more commonly seen when the CNB identified stromal overgrowth, necrosis, and diagnosis of FEL favoring PT. On multivariable analysis, a final diagnosis of PT was associated with age >50 years, larger tumor size >2 cm, stromal overgrowth, and ≥1 mitoses/10 high power fields (HPF) on CNB. Patients who were observed had smaller tumors compared with those who underwent excision. CONCLUSION: In this 10-year single-institution experience of FEL, the upstage rate to PT was 25.8%. Excision of FEL is recommended. Furthermore, the observation of lesions appeared to be safe in select cases, specifically in patients with smaller tumor size.

Enormous Gallstone Discovered in the Setting of Acute-on-chronic Cholecystitis.

Biliary disease is a common surgical problem. A unique case of a 53-year-old male with an enormous gallstone precluding safe laparoscopic cholecystectomy is presented. The patient was a 53-year-old male who presented to the emergency department with a 1-day history of abdominal pain for which clinical findings were consistent with acute cholecystitis. A laparoscopic cholecystectomy was attempted, but could not be safely completed due to an enormous gallstone prohibiting attainment of the critical view of safety. The stone measured 12.2 cm × 5.2 cm × 5.2 cm. Although biliary disease is very common and its management well documented, it is rare to uncover stones larger than 5 centimeters in diameter. Clinicians should be aware that enormous gallstones require prompt surgical intervention if discovered in the elective setting to minimize future morbidity should cholecystitis develop; early elective cholecystectomy should be considered upon discovery of large gallstones to prevent encountering a gallbladder with decreased mobilization in the setting of inflamed tissues.

Clinicopathologic Characteristics and Patient Outcomes of Phyllodes Tumors: A Single Institution Experience.

Phyllodes tumors (PT) are rare fibroepithelial neoplasms that are classified as benign, borderline, or malignant. Patients with PT diagnosed between 2009 and 2019 were identified from a prospectively maintained single institutional database. 76 patients with PT were included; 47 (61.8%) were benign, 9 (11.8%) were borderline, and 20 (26.3%) were malignant. The mean age at diagnosis was 52. Surgical treatment of benign PT included excisional biopsy in 31 (66.0%) patients, segmental mastectomy in 15 (31.9%), and mastectomy in 1 (2.1%). Among patients with borderline PT, operative management was excisional biopsy in 4 (44.4%) and segmental mastectomy in 5 (55.6%). Of those with malignant PT, 7 (35.0%) were treated with excisional biopsy alone, 9 (45.0%) had lumpectomy (segmental mastectomy), and 4 (20.0%) underwent mastectomy. Malignant PT had a higher rate of necrosis compared to borderline or benign PT (25.0% vs 0% vs 4.3%, P = .016). Four patients had recurrent PT. Final positive margins were associated with recurrence (P = .044). The median overall follow-up time was 86.3 months (range 1.5-1414.1 months), and no deaths occurred among patients with malignant PT. Overall, recurrence rates of PT are low but may be increased by presence of positive margins.

Commission on Cancer CP3R Compliance Rates for Treatment of Patients With Triple Negative and HER2+ Breast Cancer: A National Cancer Database Analysis.

BACKGROUND: Cancer Program Practice Profile Reports (CP3R) metrics were released by the Commission on Cancer to provide standards for high-quality care. One metric is the recommendation of combination chemotherapy or chemo-immunotherapy (CIT) within 120 days of diagnosis for women under 70 with AJCC T1cN0M0 or Stage IB-III HER2+ or hormone receptor negative breast cancer ([Multi-agent chemotherapy] MAC). Our study assesses national concordance rates for MAC and CIT. METHODS: The National Cancer Database was queried from 2004-2014. RESULTS: 122,045 patients met criteria, of whom treatment for 101,800 (83.4%) patients was concordant with MAC and CIT. Treatment concordance increased from 75.7% in 2004 to 89.5% in 2014. For HER2+ patients, use of CIT treatment downtrended with progression of pathological stage, from 70.1% (stage I) to 58.1% (stage III). Mean overall survival of patients whose treatment was concordant with MAC and CIT was longer than that of patients who were non-concordant (146.6 vs 143.8 months, P <.01). On Cox regression, there was a survival benefit for concordant patients who were treated at academic hospitals (HR .89, 95% CI 0.802-.976) and had private insurance (HR .76, 95% CI 0.65-.89). CONCLUSION: Compliance with MAC and CIT has improved over the past decade and is associated with a significant improvement in overall survival.

Comparison of multiple oncotype DX® from the same patient.

For women with breast cancer in whom multiple Oncotype DX® Recurrence Scores (RS) are obtained, RS concordance utilizing current NCCN recommendations has not been evaluated. Patients with two or more RS were identified. RS were stratified by NCCN guidelines and compared for concordance. Twenty-four patients were evaluated. RS concordance varied by tumor type: 100% in the same tumor, 91.7% in multiple ipsilateral tumors, 71.4% in contralateral tumors, and 66.7% in in-breast recurrent tumors. RS concordance for multiple assays in the same patient is not high enough to omit Oncotype DX® testing for each tumor.

A cross-sectional study of breast pain in a diverse population of breast cancer patients.

BACKGROUND: Breast cancer is the most common cancer in women, and postoperative breast pain has been reported to be anywhere from 25% to 60%. However, there is sparse data regarding racial/ethnic differences in breast pain among breast cancer patients. METHODS: We performed a cross-sectional anonymous survey of breast cancer patients from the Hawaii Cancer Consortium over a 6-week period between 2019 and 2020. The 237 breast cancer participants were ages 29 to 98, 74% Asian, and mainly from outpatient oncology clinics. We evaluated the prevalence of breast pain in a diverse group of breast cancer patients and characterized the pain using a modified short-form McGill pain questionnaire (sfMPQ). RESULTS: Eighty-fourrespondents(35.4%) reported breast pain. On univariable analysis, we found significant racial/ethnic differences in the amount of breast pain, where Chinese and Japanese participants reported significantly less pain compared to White participants on a 10-point pain scale. We found differences in breast pain according to age and endocrine therapy use as well as survey location, however, no differences were seen according to chemotherapy, radiation, or breast surgery. Based on the sfMPQ, the most common descriptors of breast pain were sensory (throbbing, shooting, and stabbing) compared to affective (tiring-exhausting, sickening, fearful, and punishing-cruel) characteristics. Although they were described as mild and intermittent, in women with breast pain, 33.4% reported the breast pain affected their sleep, 16.7% their work, and 15.4% their sexual activity. CONCLUSIONS: Breast pain is a significant problem in our breast cancer community. This survey assessment has informed our understanding of breast pain in our diverse population. In turn, we are developing culturally appropriate pain management strategies to treat this challenging symptom common in breast cancer survivors.

An Uncommon Pairing of common Tumors: Case Report of Ductal Carcinoma in situ Within Fibroadenoma.

Fibroadenomas are common benign tumors of the female breast. In the appropriate clinical setting, they are often managed expectantly without excision. Rarely, cancer may arise within a fibroadenoma, and this diagnosis mandates prompt treatment for malignancy. We present the case of a 70-year-old Samoan woman with ductal carcinoma in situ (DCIS) arising within a fibroadenoma. Health care practitioners should be aware of the possibility, particularly in older women, of finding carcinoma within a fibroadenoma, which informs the rationale for prompt surgical evaluation and follow up of all breast masses.

Outcomes of abdominal surgery in patients receiving mechanical ventilation for more than 48 hours.

BACKGROUND: Abdominal surgery in critically ill patients has high mortality, contributing to high US healthcare costs. This study sought to identify specific predictors of mortality in this population. METHODS: Using the National Surgical Quality Improvement Program database 2006 to 2012, we identified 4,901 patients who were intubated for more than 48 hours before undergoing common abdominal procedures. Mortality and predictors of mortality were determined using chi-square and/or regression analysis. RESULTS: Overall 30-day mortality was 44.2% with increasing mortality for additional procedures performed. Ventilated patients with the following preoperative risk factors were 2 to 3 times as likely to die within 30 days of surgery: age greater than 65-years old, coma, preoperative international normalized ratio greater than 3.0, esophageal varices, and disseminated cancer. CONCLUSIONS: Mortality is significant in ventilated patients who undergo abdominal surgery and is especially high with advanced age, disseminated cancer, and complications of liver disease. Physicians should carefully discuss this with patients and/or family and consider palliative options when appropriate.

Trial and error: investigational drug induced liver injury, a case series report.

This is a case report series of four patients who exhibited signs and symptoms of acute liver dysfunction during participation in a Phase I trial of a novel non-steroidal anti-inflammatory drug (NSAID) designed to inhibit microsomal prostaglandin synthase 1 (MPGES1). Within one month of trial initiation, all four patients presented with epigastric pain, fatigue, nausea, and increasing liver function tests (LFTs). Two out of four patients required hospitalization, underwent liver biopsies, and were treated with N-acetylcysteine. The remaining two patients were managed as outpatients. Liver biopsies were consistent with drug induced liver injury (DILI). Within three months of stopping the investigational drug, symptoms subsided and LFTs normalized in all patients. This case report series signifies the importance of NSAIDs and novel drug agents in general as potentially hepatotoxic substances, the need for a high level of suspicion of DILI when considering possible etiologies of acute liver failure, and the need for prompt withdrawal of the causative agent in management of patients presenting with DILI.
