Project description:BackgroundAlthough the ACOSOG Z0011 study showed that axillary lymph node dissection (ALND) could be avoided in a specific population of sentinel lymph node-positive patients, it is not widely accepted by Chinese surgeons. We conducted a prospective single-arm study to confirm whether or not the results of Z0011 are applicable to Chinese patients.MethodsPatients conforming to the Z0011 criteria were prospectively enrolled at the Peking University People's Hospital Breast Center from November 2014 to June 2019. The clinicopathological features of the study group were compared with those of the Z0011 study group. Lymphedema after surgery, the incidence of local-regional recurrence, and survival were analyzed.ResultsOne hundred forty-two patients who met the Z0011 eligibility criteria were enrolled in this study; 115 underwent sentinel lymph node biopsy (SLNB) alone. Compared with the Z0011 trial, younger patients were included (median age, 52 [26-82] years vs 54 [25-90] years; P = 0.03). For clinical T stage, tumor histology, hormone status, lymphovascular invasion, and the number of positive sentinel lymph nodes (SLNs), no statistically significant differences were observed. More patients received adjuvant chemotherapy and endocrine therapy in this study (90.85% vs 58.0% and 80.99% vs 46.6% respectively, P <0.001). A similar percentage of patients received radiotherapy, but more nodal radiotherapy procedures were carried out in our study (54.5% vs 16.9%). After a median follow-up of 29 months, only 1 patient (0.9%) had ipsilateral breast tumor recurrence, and no regional recurrence occurred.ConclusionOur study showed that it is achievable to avoid ALND in patients eligible for Z0011 in China.Trial registrationClinicalTrials.gov.

Project description:Little information is available on the evolvement of chemotherapeutic regimens administered to Chinese females with breast cancer. We retrospectively analyzed demographic, pathological and chemotherapeutic data of 4211 breast cancer patients, who were randomly selected from representative hospitals of 7 traditional areas in China between 1999 and 2008. A total of 3271 cases (77.7%) received adjuvant chemotherapy, 558 (13.3%) received neoadjuvant chemotherapy, and 392 (9.3%) received chemotherapy for metastatic disease. In the adjuvant setting, higher percentage of patients with younger age, advanced stage, hormone receptor (HR) negative or HER2 positive disease received chemotherapy (P<0.001). The use of CMF (cyclophosphamide, methotrexate and 5-fluorouracil) in adjuvant chemotherapy decreased significantly from 1999 to 2008, while the use of anthracycline-based (without taxanes) regimens increased in the first 5 years, followed by increased use of regimens containing both anthracyclines and taxanes. Women with locally advanced disease received more neoadjuvant chemotherapy. The percentage of neoadjuvant regimens containing anthracyclines and taxanes increased during this period. In first-line chemotherapy of metastatic disease, 87.5% of cases received combined chemotherapy, and platinum-based regimens were also major choices aside from anthracyclines and taxanes. In second-line chemotherapy, 80.3% received combined chemotherapy, and the combination of taxane and platinum was the most common choice. In conclusion, major changes have taken place in breast cancer chemotherapy in China during this 10-year interval, which reflected the incorporation of key evidence and guidelines into Chinese medical practice.

Project description:BackgroundWith Sepsis-3, the increase in sequential organ failure assessment (SOFA) as a clinical score for the identification of patients with sepsis and quickSOFA (qSOFA) for the identification of patients at risk of sepsis outside the intensive care unit (ICU) were introduced in 2016. However, their validity has been questioned, and their applicability in different settings and subgroups, such as hematological cancer patients, remains unclear. We therefore assessed the validity of SOFA, qSOFA, and the systemic inflammatory response syndrome (SIRS) criteria regarding the diagnosis of sepsis and the prediction of in-hospital mortality in a multicenter cohort of hematological cancer patients treated on ICU and non-ICU settings.MethodsWe retrospectively calculated SIRS, SOFA, and qSOFA scores in our cohort and applied the definition of sepsis as "life-threatening organ dysfunction caused by dysregulated host response to infection" as reference. Discriminatory capacity was assessed using the area under the receiver operating characteristic curve (AUROC).ResultsAmong 450 patients with hematological cancer (median age 58?years, 274 males [61%]), 180 (40%) had sepsis of which 101 (56%) were treated on ICU. For the diagnosis of sepsis, sensitivity was 86%, 64%, and 42% for SIRS, SOFA, and qSOFA, respectively. However, the AUROCs of SOFA and qSOFA indicated better discrimination for sepsis than SIRS (SOFA, 0.69 [95% CI, 0.64-0.73] p?<?0.001; qSOFA, 0.67 [95% CI, 0.62-0.71] p?<?0.001; SIRS, 0.57 [95% CI, 0.53-0.61] p?<?0.001).In-hospital mortality was 40% and 14% in patients with and without sepsis, respectively (p?<?0.001). Regarding patients with sepsis, mortality was similar in patients with positive and negative SIRS scores (39% vs. 40% (p?=?0.899), respectively). For patients with qSOFA ??2, mortality was 49% compared to 33% for those with qSOFA <?2 (p?=?0.056), and for SOFA 56% vs. 11% (p?<?0.001), respectively. SOFA allowed significantly better discrimination for in-hospital mortality (AUROC 0.74 [95% CI, 0.69-0.79] p?<?0.001) than qSOFA (AUROC 0.65 [95% CI, 0.60-0.71] p?<?0.001) or SIRS (AUROC 0.49 [95% CI, 0.44-0.54] p?<?0.001).ConclusionsAn increase in SOFA score of ??2 had better prognostic accuracy for both diagnosis of sepsis and in-hospital mortality in this setting, and especially on ICU, we observed limited validity of SIRS criteria and qSOFA in identifying hematological patients with sepsis and at high risk of death.

Project description:Patients' self-reporting is increasingly considered essential to measure quality-of-life and treatment-related side-effects. However, if multiple patient-reported instruments are used, redundancy may represent an overload for patients. Patient-Reported Outcomes Common Terminology Criteria for Adverse Events (PRO-CTCAE) are a tool allowing direct patients' reporting of side-effects. We tested psychometric properties of a selected list of PRO-CTCAE items, in a cohort of 303 breast cancer patients, using validated instruments for quality of life assessment as anchors. The analysis of convergent validity with HADS (Hospital Anxiety and Depression Scale) and EORTC BR-23 sub-scales, and the analysis of responsiveness with the PGIC (Patients Global Impression of Change) score supported that a selected list of PRO-CTCAE symptoms might represent a standardized, agile tool for both research and practice settings to reduce patient burden without missing relevant information on patient perceptions. Among patients using digital devices, those with a higher education levels required shorter time to fulfil questionnaires. In conclusion, a selected list of PRO-CTCAE items can be considered as a standardized, agile tool for capturing crucial domains of side-effects and quality of life in patients with breast cancer. The study is registered on clinicaltrials.gov (NCT04416672).

Project description:There are different characteristics of BC in developing countries and developed countries. We intended to study the factors which influence the survival and prognosis of BC between southern China and the United States. (a) To study the two groups BC patients in southern China from 2001 to 2016 and SEER database from 1975 to 2016. (b) To register, collect and analyze the clinicopathological features and treatment information. Our study found that there are significant differences in tumor size, positive lymph node status and KI-67 between southern China and SEER cohort (P < 0.000). The positive lymph node status may be one of the causes of difference of morbidity and mortality of BC patients in China. Furthermore, the differences in treatment methods may also account for the differences between China and seer databases.

Project description:Purpose: Models for predicting postoperative overall survival of patients with metaplastic breast cancer have not yet been discovered. The purpose of this study is to establish a model for predicting postoperative overall survival of metaplastic breast cancer patients. Methods: Patients in the Surveillance, Epidemiology, and End Results database diagnosed with MBC from 2010 to 2015 were selected and randomized into a SEER training cohort and an internal validation cohort. We identified independent prognostic factors after MBC surgery based on multivariate Cox regression analysis to construct nomograms. The discriminative and predictive power of the nomogram was assessed using Harrell's consistency index (C-index) and calibration plots. The decision curve analysis (DCA) was used to evaluate the clinical usefulness of the model. We verify the performance of the prediction model with a Chinese multi-center data set. Results: Multifactorial analysis showed that age at diagnosis, T stage, N stage, M stage, tumor size, radiotherapy, and chemotherapy were important prognostic factors affecting OS. The C-index of nomogram was higher than the eighth edition of the AJCC TNM grading system in the SEER training set and validation set. The calibration chart showed that the survival rate predicted by the nomogram is close to the actual survival rate. It has also been verified in the SEER internal verification set and the Chinese multi-center data set. Conclusion: The prognostic model can accurately predict the post-surgical OS rate of patients with MBC and can provide a reference for doctors and patients to establish treatment plans.

Project description:VPAC1 encodes G-protein-coupled receptors expressed on all breast cancer (BC) cells at the onset of the disease, but not on benign lesions. Our extensive preclinical studies have shown that (64)Cu-TP3805 has a high affinity for VPAC1, is stable in vivo, and has the ability to distinguish spontaneously grown malignant BC masses from benign lesions. Our long-term goal is to develop (64)Cu-TP3805 as an agent to perform in vivo histology, to distinguish malignant lesions from benign masses noninvasively and thereby avoid patient morbidity and the excess economic costs of benign biopsies.(18)F-FDG obtained commercially served as a control. (64)Cu-TP3805 was prepared using a sterile kit containing 20 μg of TP3805. Radiochemical purity and sterility were examined. Nineteen consenting women with histologically proven BC were given 370 MBq of (18)F-FDG. One hour later, 6 of these patients were imaged with PET/CT and 13 with positron emission mammography (PEM). Two to 7 d later, 6 PET/CT patients received 111 MBq (± 10%) (n = 2), 127 MBq (± 10%) (n = 2), or 148 MBq (± 10%) (n = 2) of (64)Cu-TP3805 and were imaged 2 and 4 h later. Thirteen PEM patients received 148 MBq (± 10%) of (64)Cu-TP3805 and were imaged 15 min, 1 h, 2 h, and 4 h later. Standardized uptake value (SUV) was calculated for PET/CT patients, and PUV/BGV (PEM uptake value/background value) was calculated for PEM patients. Tumor volume was also calculated.The radiochemical purity of (64)Cu-TP3805 was 97% ± 2%, and specific activity was 44.4 GBq (1.2 Ci)/μmol. In 19 patients, a total of 24 lesions were imaged (15 invasive ductal carcinoma, 1 high-grade mammary carcinoma, 3 lobular carcinoma, 1 invasive papilloma, and 4 sentinel lymph nodes). All lesions were unequivocally detected by (64)Cu-TP3805 and by (18)F-FDG. The average tumor volume as determined by PET/CT with (64)Cu-TP3805 was 90.6% ± 16.1% of that with (18)F-FDG PET/CT, and the average SUV was 92% ± 26.4% of that with (18)F-FDG. For PEM, the tumor volume with (64)Cu-TP3805 was 113% ± 37% of that with (18)F-FDG and the PUV/BGV ratio was 97.7% ± 24.5% of that with (18)F-FDG.(64)Cu-TP3805 is worthy of further investigation in patients requiring biopsy of suggestive imaging findings, to further evaluate its ability to distinguish malignant lesions from benign masses noninvasively.

Project description:BackgroundAcceptability and tolerance of chemotherapy on patients treated for breast cancer remain challenging. Complementary approaches such as hypnosis may have a favorable impact both at the time of announcing and during chemotherapy, due to the notorious anxiety, distress, and self-perceived dysfunction. The objective of the study was that the patients complied with at least four self-hypnosis sessions out of the six cycles of chemotherapy.MethodsThis open, prospective longitudinal study assessed feasibility of compliance to self-hypnosis during chemotherapy in an outpatients setting. Training sessions were given by a hypnotherapist. Throughout each cycle of chemotherapy, the patient had to use self-hypnosis to better control her anxiety or any difficulties. Nurses could offer help to the patient. Chemotherapy-associated side effects were evaluated through the NCI-Common Toxicity Criteria for Adverse Events v 4.03; moreover, side effects as pain, nausea, vomiting, fatigue, and anxiety were also evaluated during chemotherapy using a visual analogic scale. Health-related quality of life, emotional distress (anxiety and depression), and cancer-related fatigue were assessed (at inclusion, end of chemotherapy and 3 months later) using the EORTC QLQ-C30 and QLQ-BR23, HADS and MFI-20 questionnaires, respectively. The number of patients screened and actually included in the study was reported, as the reasons for refusal.ResultsThirty-five patients were included with a median age of 55 years (35-78). All patients received a hypnosis training session. The overall compliance with self-hypnosis was 68.6% (95% CI: 50.7%-83.2%), meaning that more than two thirds of patients performed at least four sessions of self-hypnosis. According to NCI-CTCAE, Grade 2 nausea and vomiting was observed in 45.7% and 22.9%, respectively, Grade 2 fatigue in 62.9%. Based on the HADS questionnaire, anxiety increased at the end of the chemotherapy and returned to the initial value 3 months later (p = .97) whereas depression significantly decrease 3 months after the end of chemotherapy with respect to the inclusion (p = .003). Role, emotional, and cognitive functioning were slightly affected throughout the treatment, in contrast to dyspnea or physical functioning.ConclusionOur study showed that self-hypnosis was feasible on patients newly diagnosed for breast cancer receiving chemotherapy.

Project description:Notch, IL-1 and leptin are known pro-angiogenic factors linked to breast cancer development, tumor aggressiveness and poor prognosis. A complex crosstalk between these molecules (NILCO) has been reported in breast cancer cell lines. However, whether NILCO biomarkers are differentially expressed in estrogen responsive (ER+), unresponsive (ER-) and triple negative (TNBC) breast cancer tissues is unknown.Expression levels of nine NILCO and targets [Notch1, Notch4, JAG1, DLL4, VEGF, VEGFR2 (FLK-1), leptin, leptin receptor (OB-R) and interleukin-1 receptor type I (IL-1R tI)] were examined via immunohistochemistry in breast cancer tissue microarrays from Chinese patients (ER+, n=33; ER-, n=21; TNBC, n=13) and non-malignant breast tissue (n=5; Pantomics, Inc.) using a semi-quantitative analysis of intensity staining, HSCORE.Categorical expression of NILCO and targets (+ or -) was similar among all cancer tissues. However, TNBC showed differential localization pattern of NILCO. TNBC showed fewer nuclei and cytoplasms positive for Notch4 and JAG1, but more cytoplasms positive for leptin. In addition, fewer TNBC stromas were positive for Notch1 and Notch4, but 100% of TNBC stromas were positive for VEGFR2. Moreover, TNBC had lower DLL4 and IL-1R tI expression. TNBC and ER- showed higher expression of EGFR, but lower expression of AR. Leptin and OB-R were detected in more than 61% of samples. Leptin positively correlated to OB-R, JAG1, VEGF, and marginally to IL-1R tI. Notch1 positively correlated to IL-1R tI. EGFR and Ki67 were positively associated to Notch1, but no associations of NILCO and targets with p53 were found.Present data suggest that NILCO components are differentially expressed in breast cancer. TNBC showed distinctive patterns for NILCO expression and localization. The complex crosstalk between leptin, IL-1 and Notch could differentially drive breast cancer growth and angiogenesis. Furthermore, the analysis of NILCO and targets using Pathway Studio9 software (Ariadine Genomics) showed multiple molecular relationships that suggest NILCO has potential prognostic biomarker value in breast cancer.

Project description:Staging laparoscopy(SL) is a recommended technique for the staging of Gastric Cancer(GC) and provides the indication for a radical surgery. Considering the medical practice in China, the standardized and regular usage of SL is yet to be spread. However, existing guidelines vary and make an ambiguity of indication for SL. Besides, the specific indication for Chinese patients remains a niche. This study aims to the essential, missing information of Chinese patients and tries to normalize the indication of LS in medical practice in China.The study is a prospective, multicenter cohort study being conducted in China with a total of 450 patients, all diagnosed with locally advanced gastric cancer (cT2-4 N0-3 M0, no evidence of intra-abdominal dissemination) through Computed Tomography(CT) and/or Endoscopic Ultrasonography(EUS). Peritoneal lavage is regularly performed during the SL. Multivariate Cox regression model and receiver-operator characteristic(ROC) analysis will be used to analyze the significant risk factors of intra-abdominal metastasis(including peritoneal dissemination and a positive cytological result).This confirmatory study will provide us with the specific positive rate of intraabdominal metastasis of GC in China, compared with empirical evidence of 20%. We expect this trial will contribute to our discovery of the specific risk factors of intra-abdominal metastasis of Chinese patients and to the stimulating and performing of minimally invasive surgical procedures.ClinicalTrials.gov : registration number NCT02172690 .
