Ten years disease-free survival after solitary brain metastasis from breast cancer

The unique case of a 51-year-old woman who developed a solitary brain metastasis as the first site of systemic disease 11 months after a total mastectomy for an undifferentiated infiltrating ductal carcinoma of her right breast is described. After surgery for the pT2pN0 carcinoma, the patient received radiotherapy of the internal mammary and supraclavicular lymph nodes. The brain metastasis was treated with surgery and adjuvant whole-brain radiotherapy to a total dose of 30 Gy in December 1984 and January 1985. Afterwards a hormonal treatment with tamoxifen was initiated, which still continues. Since then no further distant or lymph node metastases have developed. The patient is under regular after-care and undergoes various apparative examinations every 6 months. She is generally well and suffers only from a postoperatively persistent hemianopsia. This is the first case in which a disease-free survival for more than 10 years after brain metastases from breast cancer has been reported. It illustrates the specific biological behaviour of this tumour type and the chance of achieving long-term survival in very selected cases.     

Hypercalcemia in patients with breast cancer: a survival study

In a retrospective study survival after hypercalcemia in breast cancer patients has been investigated. A group of 72 patients were treated with bisphosphonate APD [3-(amino-1,1-hydroxypropylidene)bisphosphonate] and third-generation amino-containing bisphosphonates between January 1980 and October 1992. A median survival of 4.5 months was found. In a multivariate analysis, four independent prognostic factors for survival have been found: the interval between first relapse and hypercalcemia, sites of metastases at the moment of hypercalcemia, primary treatment, and the level of serum alkaline phosphatase. Patients with a flare reaction on tamoxifen treatment and patients with a normal serum alkaline phosphatase level and bone metastases only had a prolonged survival. Hypercalcemia associated with visceral metastases carried a very poor prognosis. The level of serum calcium in this series of patients was no prognostic indicator for survival.     

High serum HER2 extracellular domain levels: correlation with a worse disease-free survival and overall survival in primary operable breast cancer patients

Purpose

High serum human epidermal growth factors receptor-2 (HER2) extracellular domain (ECD) has been identified as an independent prognostic indicator of poor prognosis in metastatic breast cancer. However, its prognostic value in primary operable breast cancer was still controversial. We aim to investigate the correlation between serum HER2 ECD levels and tissue HER2 status, the association between serum HER2 ECD levels and clinicopathological characteristics, and their impacts on disease-free survival (DFS) and overall survival (OS) in primary operable breast cancer.

Methods

Two hundred and fifty-two primary operable breast cancer patients pretreated from 2002 to 2009 in Sun Yat-Sen University Cancer Center were enrolled in this study. Serum HER2 ECD was measured by chemiluminescent assay, and tissue HER2 status was accessed by immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) assay.

Results

There was a significant correlation between serum HER2 ECD levels and HER2 tissue status (P?R?=?0.36). High serum HER2 ECD levels (??15?ng/mL) were significantly associated with age (??35?years) (P?=?0.028), postmenopausal status (P?P?P?P?P?=?0.005), and progesterone receptor status (P?=?0.001). Multivariate analysis showed that high serum HER2 ECD level was an independent prognostic factor of worse DFS (P?=?0.014) and OS (P?=?0.014) in primary operable breast cancer patients.

Conclusion

Serum HER2 ECD level can reflect tissue HER2 status and can be an independent prognostic indicator for primary operable breast cancer patients.     

CMV disease in AIDS patients: incidence of CMV disease and relation to survival in a population-based study from Oslo

CMV disease is an important cause of morbidity and mortality in patients with AIDS. The purpose of this study was to investigate the incidence of CMV disease in a well-defined population of AIDS patients with a high rate of autopsy. No such study has previously been published from Scandinavia. A total of 248 patients who developed clinical AIDS in Oslo during the period 1 January, 1983 to 31 December, 1995 were included. Autopsy was performed in 152 of 213 deaths (71.3%). CMV disease was diagnosed in 95 patients. In the autopsy group, 73 patients (48%) had CMV disease, and in 52 of these patients CMV disease was first detected at autopsy. Retinitis was the most frequent manifestation, followed by adrenalitis, pneumonitis, encephalitis and gastrointestinal disease. No intravenous drug users (IVDUs) were diagnosed alive with CMV disease. All patients diagnosed with CMV disease before death had evidence of CMV disease at autopsy despite anti-CMV treatment. CMV disease was associated with increased risk of death. We conclude that CMV disease was frequent in patients with AIDS during the study period, was associated with increased mortality and was often diagnosed too late for the administration of appropriate therapy.     

Quality of adjuvant CMF chemotherapy for node-positive primary breast cancer: a population-based study

Purpose Adjuvant classical oral cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) has long been the mainstay of adjuvant chemotherapy for premenopausal breast cancer patients. The Comprehensive Cancer Center North Netherlands (CCCN) breast cancer working group performed a retrospective audit of treatment guideline adherence and quality of CMF in hospitals in the CCCN area.Methods The CMF treatment data of 251 consecutive axillary lymph node-positive breast cancer patients <50 years old, diagnosed between 1993 and 1996, were analyzed.Results Ninety-four patients (42%) completed adjuvant CMF without dose adjustment or delay. Overall median relative dose intensity (RDI) was 92.6 (IQR 85.5–97.7). Sixty patients (24%) had an RDI <85, and 7% had an RDI <65. Myelotoxicity was the main reason for reductions and delays. Of 176 irradiated patients, 96% received radiotherapy simultaneously with CMF. Median CMF dose intensity nor median duration differed between patients who underwent mastectomy, mastectomy and radiotherapy, or breast-conserving therapy. Radiotherapy did not influence the median RDI (94 without versus 92 with radiotherapy). G-CSF, administered at least once to 76 patients, did not result in a higher median RDI. Median RDI was slightly higher when >3 patients/year (P=0.014) were treated by one specialist or >10 patients classified for adjuvant chemotherapy yearly in a hospital (P=0.037).Conclusion The adherence to CMF treatment guidelines was generally good. Simultaneous radiotherapy did not affect the median RDI of CMF. G-CSF had no impact on the median RDI but patient volume did influence the RDI.Presented at the 38th Annual Meeting of the American Society of Clinical Oncology, Orlando 2002     

Chemotherapy treatment and survival in older women with estrogen receptor-negative metastatic breast cancer: a population-based analysis

To investigate the survival benefit associated with chemotherapy receipt in older women with estrogen receptor–negative (ER–) Stage IV breast cancer. DESIGN: Observational, retrospective cohort study using Cox proportional hazards regression to determine effect of chemotherapy on hazard of all‐cause mortality. The two samples were an overall sample (n=1,519) and a propensity score–matched sample (n=580) to control for selection to treatment receipt. Hazard ratios (HRs) and 95% confidence intervals (CIs) were obtained for regression models. SETTING: U.S. women within the National Cancer Institute Surveillance, Epidemiology and End Results cancer registries (SEER) linked to Medicare enrollment and claims database. PARTICIPANTS: Female Medicare beneficiaries aged 66 and older with Stage IV ER– breast cancer diagnosed between 1999 and 2005. MEASUREMENTS: Outcome measure was all‐cause death during the follow‐up period. Survival was measured as time from breast cancer diagnosis until death or last follow‐up date. Information on receipt of chemotherapy, defined as chemotherapy received within 6 months after diagnosis, was obtained from linked Medicare claims. RESULTS: One thousand five hundred nineteen ER– women diagnosed with metastatic breast cancer were identified; 494 (33%) received chemotherapy. Chemotherapy was associated with a statistically significant survival benefit (HR=0.61, 95% CI=0.54–0.70). Age did not modify the survival benefit of chemotherapy. CONCLUSION: Chemotherapy received within 6 months after diagnosis was associated with a 39% lower hazard of death within the time period for the study. These findings reflect chemotherapy use outside of the clinical trial setting and have important clinical and policy implications for the study of treatments in older women with advanced ER– breast cancer.     

Surveillance and survival in Barrett's adenocarcinomas: a population-based study

BACKGROUND & AIMS: Guidelines recommend periodic endoscopic surveillance of Barrett's esophagus (BE) patients to detect and treat early esophageal adenocarcinomas; however, no trials or population-based studies exist. We evaluated the association between endoscopic surveillance of BE and survival among esophageal/gastric cardia adenocarcinoma patients. METHODS: We studied a cohort of 23 BE patients, among 589 esophageal or gastric cardia adenocarcinoma patients diagnosed between 1990-1998 at Northern California Kaiser Permanente (a large health maintenance organization). We measured the presence of BE, detection of cancer by endoscopic surveillance, cancer stage, mortality, and potential confounders. RESULTS: BE was diagnosed in 135 of 589 adenocarcinoma patients, with 23 BE patients diagnosed greater than 6 months before cancer was diagnosed. Among these 23 patients, 73% of the surveillance-detected cancer patients (n = 15) were alive at the end of follow-up, compared with none of the patients without surveillance-detected cancers (n = 8; P = 0.001). All surveillance-detected cancer patients had low-stage disease and none died directly from cancer. The surveillance/survival association was not substantially altered by stratification for age at BE diagnosis or other potential confounders. CONCLUSIONS: Surveillance-detected BE-associated adenocarcinomas were associated with low-stage disease and improved survival. Additional studies are needed to evaluate potential biases and whether screening/surveillance programs decrease mortality among all patients in surveillance. Few patients (3.9%) had a BE diagnosed before their cancer. Thus, even if current surveillance techniques are effective, they are unlikely to substantially impact the population's mortality from esophageal cancer; better methods are needed to identify at risk patients.     

An unusual case of breast cancer relapse after 30 years of disease-free survival

A woman treated for breast cancer with mastectomy and radiotherapy in 1965 presented with a pleural mass and high CA 15.3 concentrations in a pleural effusion 30 years later and responded to endocrine therapy. The high CA 15.3 concentration was useful in diagnosis and treatment selection.     

Timing of breast cancer excision during the menstrual cycle influences duration of disease-free survival

OBJECTIVE: To study disease-free survival at 10 years in relation to timing of breast tumor excision during the menstrual cycle. DESIGN: A prospective study of consecutively treated patients with primary breast cancer. SETTING: Memorial Sloan-Kettering Cancer Center, New York. PATIENTS: Two hundred and eighty-three premenopausal patients treated by mastectomy and axillary dissection. MAIN RESULTS: When the tumor was excised during the follicular phase, approximated by setting the putative day of ovulation on day 14 after the onset of last menses, a higher recurrence risk (43%) was observed compared with excision later in the menstrual cycle (29%, P = 0.02). The rate peaked among patients treated between days 7 and 14 and was lowest between days 20 and 30. Multivariate analysis using the Cox regression model to control for tumor size, nodal status, estrogen receptor status, adjuvant chemotherapy, and family history indicated that the hazard rate of breast cancer recurrence after excision during the follicular phase was 1.53 (95% Cl, 1.02 to 2.29). Stratification by nodal status indicated that the effect of phase was statistically significant only among patients with positive nodes (hazard ratio, 2.10; Cl, 1.19 to 3.70). CONCLUSIONS: Our results support the hypothesis that the risk for recurrence may be affected by the hormonal milieu of the menstrual cycle; these findings must be confirmed, however, by a prospective study in which cycle phase at time of tumor excision is biochemically documented.     

Clinicopathological characteristics and survival outcomes in neuroendocrine prostate cancer: A population-based study

Objective:This study aimed to investigate the clinicopathological features and the survival outcomes of neuroendocrine prostate cancer (NEPC).Methods:Within the Surveillance, Epidemiology, and End Results (SEER) database of the National Cancer Institute, we identified a total of 510 patients with NEPC between 2006 and 2015. Age-adjusted incidence rates were evaluated in the study by the SEER∗Stat Software version 8.3.6. Kaplan–Meier analysed assessed overall survival (OS) after stratification according to marital status, age, histologic subtype, metastatic status, and treatment. The significant differences were assessed in a log-rank test. Univariate and multivariate cox hazard regression analysis were performed to determine independent predictors of OS.Results:From a total of 560,124 patients with prostate cancer diagnosed between 2006 and 2015, we identified 510 cases of de novo NEPC. Regarding histology, among all the NEPC, 329 (64.5%) patients were diagnosed as small cell carcinoma, 181 (39.8%) were nonsmall cell carcinoma. The overall age-adjusted incidence of NEPC statistically significantly increased from 0.321/1,000,000 person-years in 2006 to 0.587/1,000,000 person-years in 2015. The median OS in our study cohort was 9 months (95% CI, 8–10 months). Multivariate cox regression analysis showed that age, histologic subtype, and stage were independent prognostic factors for NEPC patients. The majority of NEPC (78.2%) were metastatic at diagnosis. In terms of treatment, for metastatic tumor patients, chemotherapy was the most effective therapy. Chemotherapy increased the OS of patients with regional (distant) metastases from 8 months (5 months) to 13.5 months (9 months).Conclusion:NEPC is extremely rare but the incidence of NEPC has been increasing in the past years. The prognosis of NEPC is poor because most cases are diagnosed at metastatic stage. The patients with metastases are typically treated with chemotherapy and chemotherapy shows survival benefits in both regional and distant metastatic tumor patients.     

Prognostic significance of molecular subtype,metastatic site and primary tumor surgery for survival in primary metastatic breast cancer: A SEER-based study

The incidence of primary metastatic breast cancer (PMBC) has not decreased despite the increasing popularity of mammography screening and data on the survival among these patients are limited. Therefore, we conducted an extensive population-based study to investigate the factors influencing the survival of patients with PMBC.We identified 14,306 patients with de novo stage-IV breast cancer using the Surveillance, Epidemiology, and End Results data from 2010 to 2015. The overall survival (OS) time and breast cancer-specific survival (BCSS) time were compared by the Kaplan-Meier method. Univariate and multivariate analyses were performed to determine the effect of different prognostic factors.Patients with hormone receptor positive/human epidermal growth factor receptor 2 positive showed the longest median survival time in OS (39 months) and BCSS (43 months), and those with triple negative exhibited the shortest in OS (11 months) and BCSS (12 months). We concluded that patients who had undergone primary tumor surgery had better survival than those who did not. The incidence of distant visceral metastasis in the whole cohort was as follows: bone, lung, liver, and brain. This study also substantiated that patients with only brain metastasis had poorer survival than patients with metastasis at multiple sites metastasis, not including brain metastasis (P < .0001).This study confirmed that molecular subtypes, metastatic site and primary tumor surgery were associated with the survival of PMBC patients.     

Treatment and survival of 38 female breast lymphomas: a population-based study with clinical and pathological reviews

Breast lymphomas are rare and consensus about their treatment is lacking. A population-based study of 38 breast lymphomas, registered in the databases of two Comprehensive Dutch Cancer Centers from 1981 to 1999, was performed. The median age of all female patients was 65 years (20-92): 25 patients had localized and 13 patients had disseminated lymphoma. The most common type was diffuse large B-cell lymphoma (DLBCL), which accounted for 17 of the localized and 4 of the disseminated cases. Burkitt's lymphoma (BL), three being disseminated, was found in four patients. There were six extranodal marginal zone lymphomas (ENMZL), three being localized. Seven DLBCL and one BL showed additional histological features of mucosa-associated lymphoid tissue (MALT) lymphoma. Localized aggressive lymphomas treated with surgery and/or radiation therapy had relapse rates of 100% and 67%, respectively. Cyclophosphamide, hydroxydaunomycin, vincristine, and prednisone (CHOP)-like chemotherapy with or without local irradiation led to 17% relapses in patients with localized aggressive lymphoma. Median follow-up time was 32 months (0.6-218); 37% of the patients relapsed and 24% had progressive disease. Response to salvage regimens, given to 91% of the patients with recurrent disease, was poor. The 2-year overall survival rate was 63%, 72% for patients with localized disease, and 46% for patients with disseminated lymphoma. The majority of breast lymphomas are localized aggressive lymphomas that should be treated initially with CHOP-like chemotherapy with or without irradiation. The initial choice of treatment is very important because response to salvage regimens is poor.     

Racial disparities in treatment for pancreatic cancer and impact on survival: a population-based analysis

Purpose  

Pancreatic adenocarcinoma is the fourth leading cause of cancer-related deaths in both men and women. Mortality from pancreatic cancer is higher amongst blacks compared to other races. We performed this analysis with the aim of examining racial disparity for receipt pancreatic cancer treatment and its association with survival.     

The association of venous thromboembolism with survival in pediatric cancer patients: a population-based cohort study

Venous thromboembolism (VTE) is a well-recognized complication in pediatric oncology patients. Studies in adult oncology patients have suggested a potential negative association between VTE and survival, but this association has not been examined in pediatric patients yet. The aim of this study was to assess the association of VTE with survival in pediatric oncology patients. Data from all pediatric oncology patients treated at the two tertiary care centers in Atlantic Canada were pooled to create a population-based cohort. The association between VTE and survival was analyzed using a Cox proportional hazards model stratified by diagnosis group (leukemia, lymphoma, and other; sarcoma) and adjusted for age at diagnosis and sex. Out of 939 patients included in this study, 73 had a VTE (8%) and 131 (14%) patients died during the study period. Children in the leukemia/lymphoma/other group with a VTE had significantly poorer survival relative to children in the same group who did not have a VTE. Although children with sarcoma and VTE had poorer survival compared to children with sarcoma with no VTE, this association was not statistically significant. In this population-based study, we found a negative association between VTE and survival in pediatric oncology patients. If future studies confirm this association, this finding may have prognostic implications and potentially offer new avenues for the management of pediatric patients with cancer.     

Adolescent flourishing in relation to having asthma: Results from a population-based cross-sectional study

Objective: This study investigated parent report of adolescent behaviors and flourishing of adolescents with asthma from a nationwide sample. Methods: A secondary analysis of the 2011–2012 National Survey of Children's Health was conducted. There were 2,880 youth with asthma in our sample and 25,841 without asthma between 13 and 17 years of age. Analyses examined flourishing among adolescents with and without asthma and the impact of adolescent arguing, bullying, and mood difficulties on adolescent flourishing for adolescents with asthma, while controlling for sex, age, and race. Results: Findings indicated lower flourishing for youth with asthma compared to youth without asthma. Moreover, adolescents with asthma who experienced negative behaviors, such as arguing and bullying, and adolescents who were experiencing sad feelings had lower flourishing. Conclusions: The results were consistent with literature, indicating that relatively poorer behavioral and emotional functioning is related to lower flourishing in adolescents with asthma. The results highlight the importance of screening for emotional functioning in adolescents and the need for further research to understand characteristics of adolescents related to their positive functioning.

Nomogram for predicting distant metastasis of male breast cancer: A SEER population-based study

The main purpose of this study was to build a prediction model for male breast cancer (MBC) patients to predict the possibility of distant metastasis. The Surveillance, Epidemiology, and End Results database was used to obtain data on patients with MBC. The patients were divided into a training set and a validation set at a ratio of 7:3. The risk variables of distant metastasis in the training set were determined by univariate and multivariate logistic regression analyses. And then we integrated those risk factors to construct the nomogram. The prediction nomogram was further verified in the verification set. The discrimination and calibration of the nomogram were evaluated by the area under the receiver operating characteristic curve, calibration plots, respectively. A total of 1974 patients (1381 in training set and 593 in validation set) were eligible for final inclusion, of whom 149 (7.55%) had distant metastasis at the diagnosed time. Multivariate logistic regression analyses presented that age, T stage, N stage, and hormone receptor status were independent risk factors for distant metastasis at initial diagnosis of male breast cancer. Finally, the 4 variables were combined to construct the nomogram. The area under the curve values for the nomogram established in the training set and validation set were 0.8224 (95%CI: 0.7796–0.8652) and 0.8631 (95%CI: 0.7937–0.9326), suggesting that the nomogram had good predictive power. The calibration plots illustrated an acceptable correlation between the prediction by nomogram and the actual observation, as the calibration curve was closed to the diagonal bisector line. An easy-to-use nomogram, being proven to be with reliable discrimination ability and accuracy, was established to predict distant metastasis for male patients with breast cancer using the easily available risk factors.     

Coexpression of HER-2/neu and p53 is associated with a shorter disease-free survival in node-positive breast cancer patients

Breast cancer tissue was examined for overexpression of HER-2/neu and p53 oncogene proteins. Samples from 105 breast cancer patients were investigated by Western-blot analysis and their relationship to other established markers and clinical outcome was examined. In 21.0% of the cases HER-2/neu was overexpressed, and in 46.7% the p53 protein level was increased. Expression of these two oncogene products was closely correlated. Overexpression of both oncogenes was associated with larger tumour size and negative hormone receptor. The percentage of HER-2/neu and p53 overexpression was higher in node-positive patients, although statistical evaluation was not significant. While overexpression of HER-2/neu as well as p53 in node-positive patients was associated insignificantly with shorter disease-free survival, a significant difference could be documented when the disease-free survival of patients with overexpression of both oncogene proteins was compared to that of patients with no overexpression.
