Unusual painful pelvic masses: Extramedullary hematopoiesis with extramedullary multiple myeloma.

The coexistence of extramedullary hematopoiesis and extramedullary multiple myeloma can occur and present as painful pelvic masses. In such a case, normal hematopoietic cells may outnumber clonal plasma cells, posing a diagnostic challenge.

Applying Lean Kaizen to Improve Timely Computed Tomography Scan Appointments for Oncology Patients in a Safety Net Hospital.

PURPOSE: Timely radiographic studies are essential to oncology care. At our institution, a safety net hospital in a large metropolitan area, baseline assessment determined that the overwhelming majority of outpatient computed tomographic (CT) scans for oncology patients were overdue and not scheduled within 2 weeks of their first requested date. METHODS: We conducted a series of structured, interdisciplinary meetings including staff from radiology, oncology, scheduling, and administration to critically review the scheduling process utilizing Lean Kaizen quality improvement methods. A new workflow was developed in which clinic staff scheduled CT scans before clinic discharge. Three months after our initial meeting, the new workflow was launched. We set a target of decreasing the percentage of overdue scans to below 20%. RESULTS: At baseline, 87% (65 of 75) of CT scans awaiting scheduling were overdue. Data were gathered at 5 and 10 weeks after implementation of our workflow. The percentage of CT scans overdue for scheduling was 17% (9 of 53) at 5 weeks and 0.97% (1 of 103) at 10 weeks after implementation. Clinic visit durations were not affected. CONCLUSION: The Lean Kaizen QI model was successful in decreasing the rate of oncology patients overdue for CT scan scheduling with minimal effects on clinic visit durations. This study demonstrated the importance of interdepartmental collaboration and continuous monitoring for improvement. Given the success of this project, this workflow will be expanded to other outpatient clinics within our institution.

Determinants of Psychosocial Distress in Breast Cancer Patients at a Safety Net Hospital.

INTRODUCTION: Psychosocial distress screening of cancer patients is an American College of Surgeons Commission on Cancer mandate for accredited cancer programs. We evaluated psychosocial distress in breast cancer patients to characterize risk factors for high distress scores at a safety net hospital. MATERIALS AND METHODS: The psychosocial distress screening form includes a list of potential issues and a distress score scaled from 1 through 10. Psychosocial distress screening results were retrospectively analyzed, along with patient demographics and clinical data. Cochran-Mantel-Haenszel test was applied to identify predictors for high distress scores, which were defined as a score of 5 and greater. RESULTS: 775 distress screens were completed by 171 breast cancer patients. High distress scores were reported in 21.3%. Patients who had no evidence of disease at time of screening were less likely to report a high distress score compared to those who were newly diagnosed or in active treatment (odds ratio 0.51, 95% CI, 0.38-0.68, P< .0001). Patients with high distress scores were more likely to report concerns with insurance (29.1% vs. 7.6%, P< .0001), transportation (16.4% vs. 4.6%, P< .0001), housing (15.2% vs 2.1%, P< .0001), sadness/depression (63.6% vs. 14.1, P< .0001), and physical issues (89.1% vs. 52.8%, P< .0001). CONCLUSION: Status of cancer at time of screening, particularly newly diagnosed cancer and active treatment of cancer were associated with high distress scores in this patient group. While there should be an emphasis to ensure patients with these risk factors receive psychosocial distress screening, routine periodic screening for all patients should continue to be implemented to ensure quality cancer care.

A new era of neoadjuvant treatment with Pertuzumab: Should the 10-lymph node guideline for axillary lymph node dissection in breast cancer be revised?

BACKGROUND: Pertuzumab has improved pathologic complete response rates when compared with other chemotherapeutics in the treatment of HER-2 positive breast cancer patients. AIMS: We sought to determine if axillary lymph node dissections (ALNDs) yielding at least the national standard of 10 lymph nodes is lower in patients who received neoadjuvant pertuzumab. METHODS AND RESULTS: A retrospective database identified patients who underwent ALND for breast cancer. We compared the axillary lymph node retrieval rates in those who received or did not receive neoadjuvant pertuzumab. Of 139 breast cancer patients who underwent ALND, fewer than 10 axillary lymph nodes were found in 41.7% of patients who received neoadjuvant pertuzumab (P < 0.01) and 18.6% of patients who received neoadjuvant therapy without pertuzumab (P = 0.01). CONCLUSION: Neoadjuvant chemotherapy was associated with a significantly lower rate of "adequate" ALNDs as defined by current guidelines. The patient subset that received neoadjuvant pertuzumab was more likely to have fewer than 10 axillary lymph nodes retrieved.

Capecitabine-induced hypertriglyceridemia: a rare but clinically relevant treatment-related adverse event.

Capecitabine-induced hypertriglyceridemia (CIHT) represents an increasingly significant treatment-related adverse event from capecitabine given its potential for both acute complications (acute pancreatitis) and chronic metabolic complications (cardiovascular disease). The incidence of CIHT is relatively rare and the majority of cases thus far reported have been managed with lipid-lowering therapy and/or discontinuation of capecitabine followed by resumption of the drug upon normalization of triglyceride levels. We present among the first U.S. cases of CIHT to be reported in the published literature and highlight management approaches for this rare but clinically relevant adverse event. Further understanding of the mechanisms of CIHT and its long-term adverse effects as well as effective preventive strategies, interventions, and monitoring strategies are prudent given the widespread and often prolonged use of capecitabine-based chemotherapy in gastrointestinal and other cancers.

Core needle biopsy is a safe and accurate initial diagnostic procedure for suspected lymphoma.

BACKGROUND: Excisional biopsy is currently recommended for the analysis of lymphadenopathy suspicious for lymphoma. This study aims to evaluate the efficacy and safety of image-guided core needle biopsy (IGCNB) for the diagnosis of lymphoma using a standard protocol for tissue acquisition and analysis. METHODS: All IGCNBs from 2008 to 2014 performed under the study protocol were included in analysis. Demographics, pathology results, additional studies, and follow-up information were recorded. RESULTS: Seventy-three IGCNBs were performed in 71 consecutive patients. Lymphoma was diagnosed in 37 patients (51%). All 37 patients (100%) were subtyped and treated based on IGCNB results. The remaining 36 IGCNBs in 34 patients did not have subsequent diagnosis of lymphoma in a mean follow-up of 15 months (range, 0 to 54 months). There were no complications. CONCLUSIONS: IGCNB performed under a standard protocol is effective and safe and should be considered as an initial diagnostic tool for the evaluation of lymphadenopathy suspicious for lymphoma.

Fulminant phlegmasia cerulea dolens with concurrent cholangiocarcinoma and a lupus anticoagulant: a case report and review of the literature.

Phlegmasia cerulea dolens (PCD) is an aggressive and life-threatening form of venous thrombosis complicated by ischemic necrosis. Massive thrombosis extends to collateral veins resulting in venous congestion with fluid sequestration in the interstitium causing collapse of arterioles, which progresses to ischemia and, if severe, circulatory collapse and shock. The mortality rate for PCD is as high as 40%, especially when gangrene develops. PCD has been associated with acquired thrombophilias, including malignancy and antiphospholipid syndrome (APS). We present a unique case of a patient with PCD refractory to anticoagulant and thrombolytic therapy, whose fulminant course was attributed to concurrent cholangiocarcinoma and antiphospholipid antibodies identified by a positive lupus anticoagulant assay. This case highlights the importance of uncovering precipitating causes of thromboembolism, which may offer prognostic information and may necessitate therapy beyond anticoagulation and thrombolysis to reduce the morbidity of PCD. The current literature on PCD and APS, along with their associations with malignancy, is reviewed.
