There is evidence for an association between peripheral blood eosinophil count (PBEC) and response to cancer immunotherapy; however, such data is limited in metastatic triple-negative breast cancer (mTNBC). This report presents patients (n = 14) who received a combination of durvalumab and paclitaxel for mTNBC (NCT02628132). There was a statistically significant correlation (p = 0.

This trial aimed to test the safety and efficacy of Durvalumab and Paclitaxel in metastatic TNBC. In this open-label, one-arm trial, five cycles of weekly paclitaxel were delivered intravenously (IV) concurrent with Durvalumab that was given IV every 2 weeks.

Purpose: This study was designed to examine the relationship between breast cancer molecular subtypes and pathological response to neoadjuvant chemotherapy (NAC) ± trastuzumab, in locally advanced breast cancer (LABC).
Methods: Female patients with LABC (T2-T4, N0-N2, and M0) who received neoadjuvant chemotherapy + trastuzumab if HER2+ subtype, followed by surgery and radiotherapy ± hormonal therapy, were identified. The primary endpoint was pathologic complete response (pCR) in the breast and axilla (ypT0/ypN0), with final analysis on disease-free survival (DFS) and overall survival (OS).
BACKGROUND Invasive lobular carcinoma is special subtype of breast cancer that has clinical behavior and morphology distinct from other breast cancer subtypes. It accounts for 5-15% of breast cancer. Overall, HER-2 gene amplification occurs at a significantly lower rate in ILC, but also has been linked to adverse outcomes.

Immunotherapy is becoming a promising option for care of several types of cancers including triple negative breast cancer. CASE REPORT We present a case of a patient with chemo-refractory metastatic metaplastic-type of breast cancer with failures to 3 active lines of chemotherapy.

However, the mediators and the mechanisms of action are still elusive. We show here that cancer-associated adipocytes (CAAs) isolated from 10 invasive breast carcinomas are proinflammatory and exhibit active phenotypes, including higher proliferative, invasive, and migratory capacities compared to their adjacent tumor-counterpart adipocytes (TCAs).

However, the molecular basis of obesity-related breast carcinogenesis remains elusive. In this study, we have shown that obesity reduces the level of the tumor suppressor p16 protein in breast adipocytes, which showed active features and strong procarcinogenic potential both and in orthotopic tumor xenografts compared to mature adipocytes from lean women.

Knowledge about these medications as well as safe handling guidelines has not kept abreast with the rapidity these medications are applied in clinical practice.

Methods: Eighty patients with LABC (T2-T4, N0-N2, M0) were enrolled to receive 24 weeks of neoadjuvant chemotherapy using epirubicin, cyclophosphamide, and 5-fluorouracil (FEC100) followed by cisplatin and docetaxel, plus trastuzumab if HER2 positive. The primary endpoint was pathologic complete response (pCR) in breast and axilla in separate HER2-negative and HER2-positive cohort.
Introduction: Venous thromboembolism (VTE) requires urgent diagnosis and treatment to avoid related complications. Clinical presentations of VTE are nonspecific and require definitive confirmation by imaging techniques. A clinical pretest probability (PTP) score system helps predict VTE and reduces the need for costly imaging studies.

Materials And Methods: Levels, cytotoxicity, and functional capacity of gammadelta T cells in peripheral blood mononuclear cells were assessed by flow cytometry, (51)Cr release, and ELISpot assays, respectively. Furthermore, sequence based typing was adopted to screen for granzyme B gene polymorphism.
Context: The World Health Organization classification of posttransplant lymphoproliferative disorders divides them into 4 main categories.
Objective: To classify cases of posttransplant lymphoproliferative disorders diagnosed in our institution according to the World Health Organization scheme and correlate the classification and clonality with clinical data.
Design: Cases of posttransplant lymphoproliferative disorders were reviewed.
Metaplastic carcinoma of the breast (MCB) is a rare form of cancer containing mixture of epithelial and mesenchymal elements in variable combinations. Few and conflicting clinical data are available in the literature addressing optimal treatment modalities, prognosis and outcome. A retrospective study was conducted to review all patients with MCB diagnosed and treated at King Faisal Specialist Hospital and Research Center between 1994-2004.
