Residual tumor uptake of [99mTc]-sestamibi after neoadjuvant chemotherapy for locally advanced breast carcinoma predicts survival

BACKGROUND: Studies utilizing serial [99mTc]-sestamibi (MIBI) scintimammography have reported accurate prediction of tumor response in patients with locally advanced breast carcinoma (LABC) undergoing neoadjuvant chemotherapy. The pathologic response of LABC to presurgical treatment regimens is a prognostic indicator of survival. The authors tested whether MIBI uptake posttherapy predicted survival. METHODS: Sixty-two patients with LABC underwent MIBI scintimammography just before chemotherapy and 2 months after treatment initiation. An additional MIBI scan was performed if treatment lasted >3 months. The affected breast was imaged within 10 minutes after injection to reflect early uptake, which the authors have shown to be related to tumor blood flow. MIBI uptake was quantified using the lesion-to-normal breast (L:N) ratio. Most patients (93%) received weekly dose-intensive doxorubicin-based treatment. Disease-free survival (DFS) and overall survival (OS) were compared with posttherapy primary MIBI uptake and with other established prognostic factors for neoadjuvantly treated LABC, namely, primary tumor pathologic response and posttherapy axillary lymph node status. RESULTS: Patients with high uptake on the last observed MIBI scan (i.e., the L:N ratio was greater than the median value) had poorer DFS and OS (P<0.01 and P=0.01, respectively). Residual MIBI uptake retained independent prognostic significance in preliminary multivariate analysis that included other established prognostic markers. CONCLUSIONS: High primary breast tumor MIBI uptake after neoadjuvant chemotherapy predicted poor survival, suggesting serial MIBI imaging may provide a useful quantitative surrogate end point for neoadjuvant chemotherapy trials. Given the association between MIBI uptake and tumor blood flow, this prognostic capability may be related to retained tumor vascularity after treatment.     

Inflammatory breast cancer (IBC) and patterns of recurrence: understanding the biology of a unique disease

BACKGROUND: Inflammatory breast cancer (IBC) is the most aggressive manifestation of primary breast cancer. The authors compared the prognostic features of IBC and non-IBC locally advanced breast cancer (LABC) to gain insight into the biology of this disease entity. METHODS: This retrospective analysis consisted of 1071 patients, comprising 240 patients with IBC and 831 patients with non-IBC LABC who were enrolled in 10 consecutive clinical trials (5 from each disease group). All patients received similar multidisciplinary treatment. The authors measured time to disease recurrence for each individual site from the start of treatment to the date of disease recurrence or last follow-up (recurrence-free survival) and overall survival rates to the date of last follow-up or death. RESULTS: The median follow-up period was 69 months (range, 1-367 months). Pathologically complete response rates were 13.9% and 11.7% in the IBC and non-IBC LABC groups, respectively (P = .42). The 5-year estimates of cumulative incidence of recurrence were 64.8 % and 43.4% (P < .0001), respectively, for IBC and non-IBC LABC. IBC had significantly higher cumulative incidence of locoregional recurrence and distant soft-tissue and bone disease. The 5-year overall survival (OS) rate was 40.5% for the IBC group (95% CI, 34.5%-47.4%) and 63.2% for the non-IBC LABC group (95% CI, 60.0%-66.6%; P < .0001). CONCLUSIONS: IBC was associated with a worse prognosis and a distinctive pattern of early recurrence compared with LABC. These data suggested that investigating factors affecting "homing" of cancer cells may provide novel treatment strategies for IBC.     

Microvessel Density (MVD) in Locally Advanced Breast Cancer

Background: The aim of this study was to evaluate microvessel density (MVD) by expression of CD31 andCLEC14A in core biopsies from previously untreated patients with locally advanced breast cancer (LABC) and assessits prognostic significance. Methods: MVD was evaluated in core needle biopsies (n = 92), collected prior to anytreatment, from patients who were diagnosed with locally advanced breast cancer (LABC). Immunohistochemistry forexpression of CD31 and CLEC14A were performed on these tumours. The median duration of follow-up was 9.3 years.The effect of prognostic factors on disease free survival (DFS) and overall survival (OS) was assessed using a Log ranktest and Cox regression model. Results: The clinical factors such as age, clinical nodal stage, stage and pathologicalnodal status were found to be significant in predicting overall survival by multivariate analysis (P<0.05). Out of 92, 52tumours had blood vessels expressing CD31, whereas in the remainder, there was no expression. The mean and medianMVD of CD31 in 92 tumours was 38 and 5.5 respectively, and it was not a significant factor for predicting disease freesurvival or overall survival. When we considered the tumours (n=52) which expressed CD31, patients who had veryhigh MVD (>100), had inferior progression free survival and overall survival (P=0.5). There was no expression ofCLEC14A in any of the core needle biopsies whereas it was expressed in specimens from mastectomy from the samepatient. Conclusion: This is the first report of MVD in LABC prior to any treatment. The results suggest angiogenesiscould be a prognostic factor in LABC.

目的 分析激素受体阴性、HER-2基因过表达局部晚期乳腺癌的局部复发风险和放疗作用。方法 回顾分析1999—2011年间294例激素受体阴性、HER-2基因过表达局部晚期乳腺癌患者资料, 其中239例接受改良根治术后辅助放疗, 55例因各种原因未接受放疗, 比较两组生存率和LRR率。Kaplan-Meier法计算生存率和复发率, Logrank法检验和单因素预后分析, Cox回归模型多因素预后分析。结果 5年样本数为162例。全组56例局部复发, 5年无LRR率为79.7%, 5年OS率为70.0%。放疗显著提高了5年LRRFS率(85.1%和56.0%, P=0.000), 但两组OS率相近(71.3%和64.2%, P=0.441)。多因素分析显示辅助放疗是无LRR影响因素(RR=0.303, 95%CI 0.166~0.554, P=0.000)。结论 激素受体阴性、HER-2基因过表达局部晚期乳腺癌术后放疗显著降低了局部复发率。     

Prognostic value of body mass index in locally advanced breast cancer.

PURPOSE: The purpose of this retrospective study was to determine the association and prognostic value of body mass index (BMI) at the time of initial diagnosis in patients with locally advanced breast cancer (LABC). The analysis includes the subsets of inflammatory (IBC) and noninflammatory (non-IBC LABC) breast cancer. EXPERIMENTAL DESIGN: We identified 602 patients who had LABC treated on prospective clinical trials. BMI was divided into three groups: (a) < or =24.9 (normal/underweight), (b) 25.0 to 29.9 (overweight), and (c) > or =30 (obese). Kaplan-Meier product limit method was used to estimate survival outcomes. Cox proportional hazards were used to determine associations between survival and BMI and to test for an interaction between BMI and breast cancer type. RESULTS: Eighty-two percent had non-IBC LABC and 18% had IBC. Obese patients tended to have a higher incidence of IBC compared with overweight and normal/underweight groups (P = 0.01). Median follow up was 6 years for all patients. Median overall survival (OS) and recurrence-free survival (RFS) were 8.8 and 5.9 years, respectively. Patients with LABC who were obese or overweight had a significantly worse OS and RFS (P = 0.001) and a higher incidence of visceral recurrence compared with normal/underweight patients. In a multivariable model, BMI remained significantly associated with both OS and RFS for the entire cohort. The interactions between BMI and LABC subsets and between BMI and menopausal status were not statistically significant. CONCLUSION: Patients with LABC and high BMI have a worse prognosis. Evaluation of the biological factors associated with this observation can provide tools for additional therapeutic interventions.     

神经侵犯在新辅助放疗后ypⅠ~Ⅱ期直肠癌中的预后预测价值

背景与目的：神经侵犯在结直肠癌中有一定的预后价值。对于局部进展期直肠癌，在接受过新辅助放疗及根治性外科手术且经术后病理学检查证实淋巴结为阴性（ypⅠ~Ⅱ）的直肠癌患者中，肿瘤可能存在不同程度的退缩，而此时神经侵犯是否还有预后价值目前尚未见报道。本研究旨在探讨神经侵犯在新辅助放疗后淋巴结阴性的直肠癌中的预后价值。方法：回顾性分析美国癌症监测、流行病学和最终结果（the Surveillance, Epidemiology, and End Results，SEER）数据库2000年—2018年5 222例接受新辅助放疗术后经病理学检查证实为ypⅠ~Ⅱ期的直肠癌患者的临床病理学资料和直肠癌特异性生存资料，采用卡方检验比较有无神经侵犯两组患者之间的基线资料差异，用Kaplan-Meier法和log-rank检验比较两组之间的生存差异，运用多因素Cox回归模型分析对患者肿瘤特异性生存有影响的因素。结果：该人群中有神经侵犯者329例，无神经侵犯者4 893例。与无神经侵犯的患者相比，有神经侵犯的患者中，黑种人、癌胚抗原（carcinoembryonic antigen，CEA）升高、Ⅱ期病灶、肿瘤小于5 cm和低分化的比例更高（P<0.05）。无神经侵犯的直肠癌患者的肿瘤特异性生存显著优于有神经侵犯的直肠癌患者（5年生存率：85.3% vs 68.9%），且此种生存差异在ypⅡ期直肠癌患者中更显著。多因素Cox回归模型提示有神经侵犯是新辅助放疗后淋巴结阴性直肠癌患者的独立预后因子。结论：神经侵犯与新辅助放疗后淋巴结阴性的直肠癌患者的生存密切相关，可作为此类患者的预后评判因子。     

Serum markers and prognosis in locally advanced breast cancer

BACKGROUND: Locally advanced breast cancer (LABC) represents a heterogeneous subgroup of breast cancer with an often dismal outcome. Identifying prognostic factors has acquired great significance for the selection of optimal treatment in individual patients. METHODS: Between January 1993 and December 1997, 103 patients were treated in our institution with multimodality treatment consisting of neoadjuvant chemotherapy followed by surgery, adjuvant chemotherapy and radiotherapy; tamoxifen was added in hormone receptor-positive cases. In the search for prognostic factors well-established parameters (clinical, pathological and treatment-related) as well as new features with potential value (c-erbB-2, baseline serum levels of CA 15.3 and CEA) were included in the univariate and multivariate analysis. RESULTS: At a median follow-up of 92 months (range, 8-130), the estimated five-year cancer-specific overall survival (OS) and disease-free survival (DFS) were 71.34% and 57.7%, respectively. Among the 22 different variables studied, only 10 were significantly correlated with OS and DFS. In multivariate analysis five retained independent prognostic value for both OS and DFS: tumor grade, serum markers, features of inflammatory breast cancer (IBC), response to neoadjuvant chemotherapy and lymph node status. With cutoff values of 35 U/mL for CA 15.3 and 5 ng/mL for CEA, the probability of five-year OS (Cox hazard ratio 3.91, P = 0.0009) and DFS (Cox hazard ratio 2.40, P = 0.02) decreased from 78% to 52% and from 68% to 47%, respectively, when at least one of these markers was abnormal. CONCLUSIONS: Baseline serum levels of CEA and CA 15.3 emerged from this study as strong independent predictors of outcome in LABC, whose value adds to other established prognostic factors such as postoperative nodal status, IBC, histological grade and response to neoadjuvant chemotherapy.     

The prognostic determinants of gastric cancer treatment outcome in Omani Arab patients

BACKGROUND: Gastric cancer is the most common cancer in Oman and a leading cause of cancer death. The variation in survival rates between countries and ethnic groups has been attributed to early detection policies, differences in clinicopathological features, treatment approaches, and biological characteristics. There were no previous reports on gastric cancer from Oman and very few studies on Asian Arabs. AIM: To evaluate the impact of clinicopathological and treatment variables on the survival prospects of Omani Arab patients diagnosed with gastric cancer. METHODS: The medical records of 339 Omani Arab patients diagnosed with invasive gastric adenocarcinoma during the period 1993-2004 were retrospectively reviewed. The relative importance of clinicopathological features and surgical and medical treatments were assessed using univariate and multivariate analyses. RESULTS: Most patients had distal ulcerating-type gastric cancer and presented at advanced stages. The median survival time for the entire cohort was 12 months (95% CI 9.7-14.4) with a 5-year overall survival rate of 16.7%. On univariate analysis of 237 patients who underwent surgical resection, the following positive prognostic factors emerged as significant: early overall TNM stage, early T stage, negative lymph nodes, tumor size <5 cm, ulcerating macroscopic appearance, and curative surgical attempt. The independent prognostic factors on multivariate analysis were T stage and lymph node involvement. CONCLUSION: The overall T and N stages are the most important determining factor for survival in Omani Arab patients. More efforts need to be made for the early detection of gastric cancer in developing countries such as Oman, while continuing to employ the standard surgical and medical treatments.

Comparative outcomes of pancreatic neuroendocrine neoplasms: A population-based analysis of the SEER database

BackgroundA paucity of data exists regarding the natural history and survival outcomes of pancreatic neuroendocrine neoplasms (PanNENs), a rare histological subtype which can be classified as functional (F-PanNENs) and non-functional (NF-PanNENs). The purpose of this study is to characterize their clinicopathological features and survival outcomes in a large cohort of patients from United States.MethodsAll patients diagnosed with F-PanNENs or NF-PanNENs between 1998 and 2018 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Patient demographic, clinicopathological features and survival outcomes were analyzed. Logistic regression analysis was used to identify factors associated with NF-PanNENs diagnosis over F-PanNENs. Cox regression analysis was utilized to determine the prognostic variables for overall survival (OS) in all PanNENs patients.ResultsA total of 2347 patients were identified: 1181 in the F-PanNENs group and 1206 in the NF-PanNENs group. NF-PanNENs were larger in size, poorly differentiated, more commonly found in a head pancreas location, and had increased lymph node positivity and liver involvement compared to F-PanNENs. Patients with F-PanNENs were associated better survival outcomes than those with NF-PanNENs. Diagnosis at early year, poorer differentiation, and larger tumor size were independently correlated with NF-PanNENs diagnosis. In addition, multivariable analysis determined that age, gender, year of diagnosis, marital status, tumor grade, size, stage, number, and surgical treatment were independent prognostic factors for OS of all PanNENs patients.ConclusionThe clinicopathological characteristics and survival outcomes were significantly different between NF-PanNENs and F-PanNENs. Furthermore, we identified the clinical features correlated with NF-PanNENs diagnosis over F-PanNENs.
