Abstract
BACKGROUND Although primary cutaneous B-cell lymphomas (PCBCL) comprise 25% of all cutaneous lymphomas, their incidence in the pediatric population is unknown, and the information on pediatric PCBCL has mostly been gathered from individual case reports or series from single centers. PATIENTS AND METHODS This was a population-based, retrospective cohort study of patients in 18 cancer registries in the United States diagnosed between 2000 to 2016 through the Surveillance, Epidemiology, and End Results (SEER) program. Age-adjusted incidence rates were calculated for PCBCL in pediatric (<20 years) and adult (≥20 years) populations. Demographic, clinical, and pathological characteristics of PCBCL were compared between the two groups. RESULTS A total of 48 pediatric and 5128 adult PCBCL cases were included. Median age at diagnosis was 16.5 years and 65 years in the two groups, respectively. The major histologic subtypes of pediatric cases were marginal zone lymphoma (77.1%), followed by diffuse large B-cell lymphoma (12.5%) and follicle center lymphoma (10.4%), which were equally distributed in adults. The age-adjusted pediatric PCBCL incidence rate (per 1,000,000 person-years) was 0.12 (95% CI 0.09-0.16). The incidence in the adult population was approximately 40-fold higher than the one observed in the pediatric group (IRR 41.4, 95% CI 31.2-56.2). All 48 pediatric cases were alive during a median follow-up time of 48 months. CONCLUSIONS Pediatric PCBCL is a very rare disease affecting mostly adolescents of both sexes. The major histologic subtype is marginal zone lymphoma, and the prognosis is favorable.

A need for clarity on surgical management of breast sarcoma: Scottish sarcoma network guidelines and regional audit. J Plast Reconstr Aesthet Surg 2021; 74:1180-1192. [PMID: 33308991 DOI: 10.1016/j.bjps.2020.10.072] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Revised: 09/05/2020] [Accepted: 10/22/2020] [Indexed: 12/14/2022]
Abstract
Currently, there are no comprehensive breast sarcoma guidelines in the UK. There is therefore a need for guidelines to clarify surgical management, which we have based on data from our regional audit, current evidence, and consensus between West of Scotland Breast Cancer and Scottish Sarcoma Managed Clinical Networks. Methods and results: From 2007 to 2019, 46 patients were treated with breast sarcoma in the West of Scotland. Sarcoma Centre versus Peripheral Hospitals: Incomplete excision rate was 0% at sarcoma centre and 50% at peripheral hospitals (p = 0.0002, Odds Ratio 43). For angiosarcoma, 0% positive margin at the sarcoma centre versus 62.5% at the peripheral unit (p = 0.0036, odds ratio 39.3). Tumours treated at the sarcoma centre were larger than those treated at peripheral hospitals (92.5 versus 39.7 mm, p = 0.0009). WLE (wide local excision) versus mastectomy: Out of eight WLE patients, seven (87.5%) had positive margins, with 6 of these patients proceeding to mastectomy (i.e. 75% WLE patients ultimately had a mastectomy). The positive margin rate was significantly higher in WLE (87.5%) than in mastectomy (10.3%) (p = 0.0001, odds ratio 60.7). Survival: No difference was noted between the sarcoma centre and peripheral hospitals for overall survival (p = 0.43), stratified for tumours <5 cm (p = 0.16), and disease-free survival (p = 0.45). Conclusions: Our data strongly suggest that specific guidelines are needed for breast sarcoma, and that managing these patients according to breast carcinoma protocols in peripheral hospitals is sub-optimal. We recommend centralisation of breast sarcoma patient care to a specialist sarcoma centre, with WLE not recommended as a firstline surgical option given both the high rates of incomplete excision and subsequent need for completion mastectomy.

Abstract
OBJECTIVES The purpose of the present study was to determine whether racial disparity exists between African American (AA) and non-African American (NAA) patients with uterine endometrioid carcinoma who received similar multidisciplinary management. METHODS We identified 766 patients with endometrioid adenocarcinoma 2009 FIGO stages I-II who underwent hysterectomy. Patients were divided into two groups; AA and NAA. Recurrence-free survival (RFS), disease specific survival (DSS) and overall survival (OS) for two groups were calculated. RESULTS Median follow-up was 5.1 years. 27% were AA and 73% were NAA. All patients underwent hysterectomy and oophorectomy. 80% had peritoneal cytology examination and 69% underwent lymphadenectomy. AA patients were more likely to have higher grade tumors, and higher incidence of lymphovascular space involvement (LVSI). Although the two groups were balanced with regards to surgical staging and adjuvant treatment received, the 5-year RFS and DSS were significantly lower in AA compared to NAA patients (91% vs 84%, p=0.030; 95% vs 88%, p=0.011, respectively). Overall survival was not significantly different between the two groups. On multivariate analysis, after adjusting for other prognostic factors, race (AA vs NAA) was not a significant predictor of outcome. Grade 3 tumors and the presence of LVSI were the only two independent predictors of RFS and DSS with p ≤ 0.001 and p ≤ 0.001, respectively. CONCLUSION In this large hospital-based study, AA race was associated with a higher incidence of adverse pathological features and worse recurrence-free and disease-specific survival. However, on multivariate analysis race was not an independent prognostic factor. Further studies are needed to elucidate possible underlying molecular mechanisms for these poorer outcomes.

Abstract
PURPOSE Lung cancer is the leading cause of cancer-related mortality. Intensive care unit (ICU) use among patients with cancer is increasing, but data regarding ICU outcomes for patients with lung cancer are limited. PATIENTS AND METHODS We used the Surveillance, Epidemiology, and End Results (SEER) -Medicare registry (1992 to 2007) to conduct a retrospective cohort study of patients with lung cancer who were admitted to an ICU for reasons other than surgical resection of their tumor. We used logistic and Cox regression to evaluate associations of patient characteristics and hospital mortality and 6-month mortality, respectively. We calculated adjusted associations for mechanical ventilation receipt with hospital and 6-month mortality. RESULTS Of the 49,373 patients with lung cancer admitted to an ICU for reasons other than surgical resection, 76% of patients survived the hospitalization, and 35% of patients were alive 6 months after discharge. Receipt of mechanical ventilation was associated with increased hospital mortality (adjusted odds ratio, 6.95; 95% CI, 6.89 to 7.01; P < .001), and only 15% of these patients were alive 6 months after discharge. Of all ICU patients with lung cancer, the percentage of patients who survived 6 months from discharge was 36% for patients diagnosed in 1992 and 32% for patients diagnosed in 2005, whereas it was 16% and 11% for patients who received mechanical ventilation, respectively. CONCLUSION Most patients with lung cancer enrolled in Medicare who are admitted to an ICU die within 6 months of admission. To improve patient-centered care, these results should guide shared decision making between patients with lung cancer and their clinicians before an ICU admission.

Abstract
Population-based registries may provide data complementary to that from basic science and clinical intervention studies, all of which are essential for establishing recommendations for the management of patients in the real world. The same quality criteria apply for the evidence-based label, and both high representation and good data quality are crucial in registry studies. Registries with high coverage of the target population reduce the impact of selection on outcome and the subsequent problem with extrapolating data to nonstudied populations. Thus, data useful for clinical decision in situations not well covered by clinical studies can be provided. The potential clinical impact of data from population-based studies is exemplified with analyses from the Swedish Acute Leukemia Registry containing more than 3300 acute myeloid leukemia (AML) patients diagnosed between 1997 and 2006 with a median follow-up of 6.2 years on (1) the role of intensive combination chemotherapy for older patients with AML, (2) the impact of allogeneic stem cell transplantation on survival of younger patients with AML, and (3) the continuing problem with early deaths in acute promyelocytic leukemia. We also present the first Web-based dynamic graph showing the complex interaction between age, performance status, the proportion of patients given intensive treatment, early death rate, complete remission rate, use of allogeneic transplants, and overall survival in AML (non-AML).

Racial disparities in histopathologic characteristics of uterine cancer are present in older, not younger blacks in an equal-access environment. Gynecol Oncol 2011; 123:76-81. [PMID: 21741078 DOI: 10.1016/j.ygyno.2011.06.027] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2011] [Revised: 06/15/2011] [Accepted: 06/20/2011] [Indexed: 11/15/2022]
Abstract
OBJECTIVE We sought to determine whether racial disparities in tumor characteristics among uterine cancer patients persisted, and varied by age, in an equal-access healthcare population. METHODS The distributions of tumor histology, stage and grade by race were compared for uterine cancers diagnosed from 1990 to 2003 using data from the U.S. Department of Defense's Automated Central Tumor Registry. Comparisons were conducted overall and stratified by age (<50, ≥50) using the Chi-square test. RESULTS Of 2582 uterine tumors identified, 2057 (79.7%) were diagnosed among White women and 183 (7.1%) among Black women. Among all women analyzed, Blacks were more likely than Whites to present with non-endometrioid tumors (47.7% vs 23.5%, p<0.01), non-localized tumors (31.8% vs 24.5%, p=0.02), and poorly differentiated tumors (20.5% vs 15.0%, p<0.01). Among women 50 years and older, similar significant racial disparities were observed. However, no significant racial differences were observed among young patients. When comparisons were restricted to endometrioid histology adenocarcinomas, trends in age-specific disparities for older women were observed. CONCLUSIONS Our study suggests that racial disparities in uterine cancers persist between Blacks and Whites in an equal-access population. Blacks endure higher stage and grade tumors, and more aggressive histologies. This disparity in clinicopathologic factors is confined to women older than 50 years. Multiple factors such as racial variation in age-related health knowledge/behavior and estrogen metabolism may be related to the racial disparity.
