Background: Implementing mammogram screening means that clinicians are seeing many breast cancers that will never develop metastases. The purpose of this study was to identify subgroups of breast cancer patients who did not present events related to long-term breast cancer mortality, taking into account diagnosis at breast screening, absence of palpability and axillary involvement, and genomic analysis with PAM50.
Patients And Methods: To identify them, a retrospective observational study was carried out selecting patients without any palpable tumor and without axillary involvement, and a genomic analysis was performed with PAM50.
Background And Objective: Reproductive history influences breast cancer risk. We analysed its association with tumour subtype and survival in premenopausal women.
Patients And Methods: Retrospective, observational study of premenopausal women with stage I-III breast carcinoma in the last 20 years.
Background And Objective: To identify subgroups with good progress over an extended period, we used diagnostic screening, tumour palpability, tumour phenotype, and node involvement.
Patients And Methods: We identified patients with good progress by means of a descriptive, observational and retrospective study.
Results: Of 746 patients diagnosed with node-negative breast cancer between 2001 and 2015: 110 (14.
(Pro)renin receptor (PRR) is being investigated in several malignancies as it activates pathogenic pathways that contribute to cell proliferation, immunosuppressive microenvironments, and acquisition of aggressive neoplastic phenotypes. Its implication in urothelial cancer (UC) has not been evaluated so far. We retrospectively evaluate the prognostic role of PRR expression in a series of patients with invasive UC treated with radical cystectomy and other clinical and histopathological parameters including p53, markers of immune-checkpoint inhibition, and basal and luminal phenotypes evaluated by tissue microarray.

Despite early screening programs, more than half of CRC patients are diagnosed at advanced stages. Fibroblast activation protein-α (FAP) expression in cancer-associated fibroblasts (CAFs) has been associated with a higher risk of metastases and poor survival.

Its biological role has recently been related to cancer progression and in this study, we investigated its relevance in colorectal cancer (CRC). To that end, we analysed the immunohistochemical expression of PRR in adenomatous polyps and CRCs from the same patients ( = 42), and in primary tumours and nodal and liver metastases from advanced CRC patients ( = 294).

To analyze the aggressiveness of care by evaluating systemic anticancer therapy (SACT) given near to death, describing this care and identifying factors that determine its use. This involves retrospective observational cohorts study.

Fulvestrant, an estrogen receptor antagonist, is indicated in the treatment of estrogen receptor-positive metastatic breast cancer in postmenopausal women. To our knowledge, this is the first described case of toxic epidermal necrolysis due to fulvestrant.

In this study we analyzed the immunohistochemical expression and fluorimetric activity of four key peptidases of iRAS in tumor tissue (n = 144) and serum samples (n = 128) from patients with renal neoplasms. Neutral endopeptidase (NEP/CD10), Angiotensin-converting enzyme-2 (ACE2), and aminopeptidase A (APA) were expressed in tumor cells whilst Angiotensin-converting enzyme (ACE) was expressed in the endothelial cells of intratumor blood vessels.

Because of their role in tumorigenesis and stability in body fluids, microRNAs (miRNAs) are emerging as a promising diagnostic tool. Our aim was to identify miRNAs deregulated in breast tumors and evaluate the potential of circulating miRNAs in breast cancer detection.
