The purpose of this pilot is to provide credible performance estimate information in order to conduct a subsequent pivotal reader study.
To assess feasibility of postoperative IMRT with concomitant boost in moderate-high risk breast cancer in terms of late toxicity and local control
This trial was a retrospective study on postoperative accelerated hypofractionated IMRT (MARA-1) in patients with early stage breast carcinoma, to compare late toxicity after this treatment and standard fractionated RT delivered with 3D-CRT.
Patient-assisted compression (PAC) allows the patient to participate in controlling the amount of compression force during mammography and is a personalized approach that has demonstrated successful reduction in discomfort experienced during mammography. GE Healthcare's Senographe Pristina, an innovative mammography platform that provides both two-dimensional (2D) and three-dimensional (3D) imaging capabilities, offers both standard and patient-assisted compression modes. This study will evaluate image quality and clinical workflow as it relates to use of PAC with the Senographe Pristina 3D.
The sensory recovery of the breast remains an undervalued aspect of breast reconstruction and surgical reinnervation is not regarded as a priority by most reconstructive surgeons. A prospective study was conducted of all patients who underwent either innervated or non-innervated DIEP flap breast reconstruction in Maastricht University Medical Center and returned for follow-up between September 2015 and July 2017. Semmes-Weinstein monofilaments were used for sensory testing of the breast. This study showed that nerve coaptation in DIEP flap breast reconstruction resulted in a significantly improved sensation of the reconstructed breast compared to non-innervated flaps.
Breast cancer, the first female cancer, affects one in eight women in her lifetime. The increase and uneven distribution of its prevalence throughout the world cannot be fully explained either by the increase in life expectancy, or by genetic factors present in less than 10% of cases, or by early detection, or by the use of hormone therapy for menopause at certain periods of time. Numerous experimental and epidemiological arguments, as well as the increased risk of breast cancer in women after 50 years of age who were exposed in utero to Distilbene prescribed for their mothers in the 1950s to 75's, suggest the involvement of environmental factors involved in early development (nutrition, alcohol, tobacco, chemical pollutants) that may act as endocrine disruptors, estrogenomimetic or intervening on other nuclear receptors such as the However, the formal demonstration of the deleterious physiopathological role of such exposure comes up against methodological difficulties in epidemiological terms: first of all, the fact that correlation is sought at the time of the discovery of breast cancer when there are critical windows of exposure (fetal, perinatal, peripubertal and pregnant) and that persistent organic products or POPs, most often lipids, are present. The objective of this project is to correlate the per-gravidic exposure to POPs (dioxins, dioxinlike, polychlorinated bisphenyls, organochlorine pesticides and flame-retardant polybrominated derivatives) and the development, within 15 years of delivery, of breast cancer, taking into account the confounding factors of classical breast cancer risk (age, reproductive events, etc.). This project benefits on the one hand from a cord blood bank set up between 2002 and 2005 (6,242 samples) carried out at the Nice University Hospital and the Grasse University Hospital, during a PHRC and on the other hand from the cancer observatory / CRISAP of the PACA Corsica region, exhaustive to more than 92% since 2005, registers which will be cross-referenced and whose cancer cases (N) will be compared to controls. The assays will be carried out after purification, using high-resolution mass spectrometry gas chromatography coupling, the quantification being carried out according to the principle of isotopic dilution. They will be carried out by LABERCA in Nantes, the national reference laboratory of the French Health Agencies ANSES and INVS and also involved in various European projects. Concentrations related to blood lipids will be expressed in quartile and analyzed separately or combined with a cumulative score taking into account confounding risk factors for breast cancer and the geolocation of the initial and final residence in relation to the incinerator of the City of Nice (Department of Public Health CHU of Nice).
Postoperative analgesia in breast surgery is a difficult and overworked issue due to extensive surgery and complex innervation of the breast. Erector spinae plane block (ESB) is a new defined regional anesthesia technique for thoracic analgesia.Main purpose of this study was to evaluate the analgesic effect of ultrasound guided double injection ESB in breast surgery.
The MARIEplus study is a prospective cohort of breast cancer patients recruited into the MARIE (Mamma Carcinoma Risk factor InvEstigation) study, a population-based case-control study of breast cancer conducted in two German study regions, Hansestadt Hamburg and Rhine-Neckar-Karlsruhe (RNK) region. Participants were identified through participating clinics and the Hamburg cancer registry between January 1st, 2001 and September 30th, 2005 in Hamburg and between August 1st, 2002 and July 31st, 2005 in the RNK study region. Patients were aged 50-74 years at histologically confirmed primary invasive (stages I to IV) or in situ breast tumor (stage 0). Comprehensive information on demographic, socio-economic, and lifestyle factors was collected at multiple time points: at recruitment by a standardized face-to-face interview and at follow-up median 6 years as well as 11 years later using computer assisted telephone interview. Vital status was assessed in 2009 and again in 2015 via the population registries and causes of death were obtained from death certificates and coded according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). Information on the clinical course was abstracted from medical records to verify clinical events either self-reported in follow-up interviews or reported by treating physicians. The studies were approved by the ethics committee of the University of Heidelberg and the University of Hamburg and conducted in agreement with the Helsinki Declaration. Written informed consent was provided by all participants at baseline and during follow-up. The primary objectives of this study are - To assess the association of modifiable lifestyle factors and personal factors, including BMI, diet, physical activity, tobacco and alcohol use, menopausal hormone therapy, socioeconomic status, with breast cancer survival, overall and according to tumor type, after accounting for established prognostic factors. - To examine the influence of genetic variants on breast cancer relapse and survival - To assess the association of lifestyle factors and their changes in the course of survivorship on subsequent breast cancer prognosis. - To assess the individual and combined association of inflammation/metabolic biomarkers as well as changes in their serum levels with subsequent breast cancer prognosis overall and according to tumor type. - To assess whether and to what extent the associations between breast cancer prognosis and lifestyle factors and/or their changes are mediated by circulating biomarker levels.
This study examines effectiveness of peer support of breast cancer patients. Half of the participants received peer support via telephone in addition to usual care and another half are give the usual care only.
Because of mammography screening increasingly more women are diagnosed with centimeter or subcentimeter node-negative breast cancer (i.e., T1abN0); these tumors account for approximately 19% of all newly diagnosed breast cancers in Sweden. Although the long term relapse-free survival rates among patients with such tumors is as high as ≥90%, some reports suggest that certain patient subgroups may have rates <75%. Firmly established prognostic and predictive factors for patients with T1abN0 tumors are, however, lacking. This is a nationwide, register-based cohort study investigating prognostic and predictive factors in women with centimeter or subcentimeter breast cancer. The study hypotheses are: 1) Established prognostic and/or predictive factors in overall breast cancer are prognostic and/or predictive factors also in centimeter or subcentimeter node-negative breast cancer; 2) The established relative reduction in risk of recurrence and death of adjuvant treatment for overall breast cancer are similar in centimeter or subcentimeter node-negative breast cancer.
