Active clinical trials for "Breast Neoplasms"

This is a retrospective, observational, multi-center clinical study of circulating tumor DNA (ctDNA) to guide late-line therapy in late-stage metastatic breast cancer patients.

All patients undergoing breast biopsy, lumpectomy, needle-localization-guided breast biopsy, and mastectomy at Einstein Medical Center Philadelphia, Einstein Medical Center Montgomery, Center One, or Einstein Elkins Park will be offered participation into the study. Patients who have documented allergies to adhesive or tape, patients taking chronic steroids, and patients with documented connective tissue, skin, or healing disorders will be excluded from the study. Risks and benefits of the study as well as risks and benefits of the procedure will be discussed with the patient by one of the investigators. If the patient elects to participate in the study, they will be assigned to incisional dressing at the time of operation with either in-line or perpendicular placement of Steri-Strips based on the patient's computer-generated randomization assignment. The patient's chart will be reviewed to determine the patient's age and comorbid conditions including obesity (pre-operative BMI), diabetes mellitus, use of anti-platelet or anticoagulant medication, or smoking. This information will be utilized to ensure that our study groups are similar in baseline demographics and pre-existing conditions. Additionally, the primary medical reason for needing breast surgery will be reviewed as well as treatment with pre-operative or post-operative chemotherapy or radiation therapy to the breast. Steri-Strips will not be removed and will be allowed to fall off naturally. At regularly scheduled 30-day and 90-day follow-up appointments, pictures will be taken of the incisional area. These photographs will be reviewed by a blinded, independent surgeon who will grade each incision according to the modified Hollander Cosmesis Scale. Statistical analysis with t-testing of the means and chi-squared testing of dichotomous variables will be performed to determine significance of the findings.

This study is to prospectively investigate the incidence of hypothyroidism after postoperative radiotherapy and identify risk factors for development of hypothyroidism. Patients with breast cancer treated with surgery followed by radiotherapy is enrolled. Thyroid function was assessed at baseline and different times after radiotherapy. The radiation technique, thyroid dose parameters and hypothyroidism are prospective evaluated, and the dose-effect relationship is analyzed.

Breast cancer is the most common cancer in women worldwide. Hormonal therapy is one of the major treatments for hormone receptor positive breast tumors. It is prescribed to 70% of breast cancer patients. Hormonal therapy can be responsible for sexual dysfunction induced by hormonal changes. Extended adjuvant hormonal therapy over 5 years increases these adverse effects. According to the third "Plan Cancer" (2014-2019), sexual dysfunction prevention and screening must be systematic as an integral part of supportive care. Nevertheless, sexual quality of life remains too rarely considered. In this study, the investigator propose to evaluate sexual quality of life of women less than 51 years old during the adjuvant endocrine therapy for localized breast cancer. The investigator also intend to collect the supportive measures or interventions used by women to overcome sexual dysfunction. Finally, this study aims to evaluate the need for sexual trouble specific management and acceptability of different methods. This project is a hot topic as the interest for oncosexuality is growing, and the need for specific management is increasing with still insufficient access to specific care.

While classification of malignant breast tumors has traditionally been made according to their histological appearance, nowadays some subtypes have been defined according to their molecular features. The different behaviors of tumors in the luminal group necessitated the need to separate this group into luminal A and B subtypes. Luminal A group has the highest prevalence among breast cancers; It includes Her2 negative tumors with low proliferative activity, mitosis rate and low histological grade. The prognosis of patients with luminal A tumors is very good and metastases are often limited to bones. Luminal-B tumors are more aggressive. There are some studies investigating the relationship between blood cytokine levels (TGFβ1, IFNγ) and breast cancer. Human studies have generally evaluated a limited number of cytokines. The study evaluating the largest number of different cytokines was an animal study, and 24 different cytokine levels were compared with healthy control rats with breast cancer. Our aim in this study is to evaluate the relationship between the differences in blood cytokine values and disease stage in Luminal A, Luminal B, and triple negative breast cancers.

The challenge of breast conserving surgery (BCS) is to obtain free resection margins, by removing the invasive tumor and the precursor cells: DCIS (Ductal Carcinoma in Situ). Consequently, 17%-25% of primary invasive breast cancer patients will need a repeat surgery. Repeat breast surgery has been associated with higher surgical risks, poorer cosmetic outcome and increased psychological and economic burden. Finding a precise method to obtain tumor- and DCIS-free resection margins during BCS is therefore strongly needed. The purpose with this study is to investigate if the need for a re-operation can be reduced by performing Digital Breast Tomosynthesis (DBT) of the resected tumor margins compared to the currently used standard X-ray during BCS.

This is a retrospective, observational, multi-center clinical study of circulating tumor DNA (ctDNA) application in late-stage breast cancers.

The study aimed to investigate the efficacy of the everolimus-containing chemotherapy in metastatic breast cancer patients with PI3K/AKT/mTOR mutations.14 cases of HER2- metastatic breast cancer patients with PI3K/AKT/mTOR mutations treated with everolimus-containing chemotherapy were retrospectively analyzed.The genetic profile in PI3K/AKT/mTOR pathway was studied.

The objective was to find out the impact of COVID-19 on stage of breast cancer at presentation and its effects on overall onco-surgical management. The investigator carried out this research to see the presenting stage of breast cancer in the participants in this pandemic and correlate its effect on stage of breast cancer and upstaging of disease

Patients with early breast cancer were randomized at the final visit of adjuvant radiotherapy to surveillance by phone calls or by mobile Noona software. After six months the groups were crossed over to the other arm. At 12 months the patients were asked their preference which was the primary end-point. At baseline, 6 months and 12 months the patients answered the other questionnaires.
