Tratamiento neoadyuvante del cáncer de mama operable
2006
Preoperative or neoadjuvant systemic treatment refers to either the first postdiagnosis systemic treatment that a patient receives or indicates that additional subsequent therapy is intended. Randomized controlled clinical trials have shown that preoperative systemic treatment offers the same disease free survival and overall survival benefits as does adjuvant systemic treatment. Neoadjuvant therapy has been found to increase the breast-conserving surgery rate. This therapy also allows to evaluate the primary tumor response to chemotherapy. Additionally, on the basis of the biologic characteristics of a tumor and differences in the response to systemic treatment, primary systemic treatment …
Fertility and breast cancer: A literature review of counseling, preservation options and outcomes.
2021
Fertility preservation is an important issue in breast cancer patients undergoing oncological treatment. Fertility counseling is a crucial need given the physical and psychological stress experienced by patients. Cryopreservation of mature oocytes is currently the standard fertility-preserving procedure. Other options such as ovarian tissue preservation or gonadal protection during chemotherapy are still experimental, but have proven effectiveness. Prompt referral to a fertility unit is highly recommended in order to ensure quality of care. In this article, we focus on the different strategies to preserve fertility in breast cancer patients, assessing also the safety of pregnancy and breast…
Biweekly cetuximab and irinotecan in advanced colorectal cancer patients progressing after at least one previous line of chemotherapy: results of a p…
2008
This is a phase II institutional exploratory trial of biweekly irinotecan and cetuximab administration regimen in metastatic colorectal cancer patients progressing to at least one previous chemotherapy line. A total of 40 patients were treated between November 2005 and November 2007 with irinotecan 180 mg m−2 and cetuximab 500 mg m−2 q2w (every 2 weeks), in every 21-day cycles, until unacceptable toxicity or progressive disease. An overall response rate of 22.5% was obtained (two complete and seven partial responses). The disease control rate was 60%. The time to progression was 3.4 months and the overall survival was 8 months. The toxicity compared very favourably to weekly cetuximab combi…
Mutational analysis ofBRCA1andBRCA2in Mediterranean Spanish women with early-onset breast cancer: Identification of three novel pathogenic mutations
2003
In Spain, the contribution of BRCA mutations to the population incidence of early-onset breast cancer was unknown. We carried out a mutational analysis of the BRCA1 and BRCA2 genes in 124 Spanish women diagnosed with breast cancer before the age 41 and who were not selected for a family history of this disease. The genetic study was performed by PCR-SSCP analysis and DNA sequencing. We identified 6 pathogenic BRCA mutations in 7 unrelated probands (5.6%; 95% CI=2.3% to 11.3%): 1 BRCA1 (c.2080delA) and 5 BRCA2 (p.Y3006X, p.Q1994X, c.9204_9217del14, c.9254_9258del5 and c.295+2T>C). Three out of 6 mutations were novel (BRCA2 p.Y3006X, c.9204_9217del14, and c.295+2T>C), and two further mutation…
Hereditary Leiomyomatosis and Renal Cell Cancer Syndrome in Spain: Clinical and Genetic Characterization
2020
Simple Summary Hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome is a very rare hereditary disorder characterized by cutaneous leiomyomas (CLMs), uterine leiomyomas (ULMs), renal cysts (RCys) and renal cell cancer (RCC), with no data on its prevalence worldwide. No genotype-phenotype associations have been described. The aim of our study was to describe the genotypic and phenotypic features of the largest series of patients with HLRCC from Spain reported to date. Of 27 FH germline pathogenic variants, 12 were not previously reported in databases. Patients with missense pathogenic variants showed higher frequencies of CLMs, ULMs and RCys, than those with loss-of-function varia…
Prevalence and Clinicopathological Characteristics of Moderate and High-Penetrance Genes in Non-BRCA1/2 Breast Cancer High-Risk Spanish Families
2021
(1) Background: Over the last decade, genetic counseling clinics have moved from single-gene sequencing to multigene panel sequencing. Multiple genes related to a moderate risk of breast cancer (BC) have emerged, although many questions remain regarding the risks and clinical features associated with these genes. (2) Methods: Ninety-six BC index cases (ICs) with high-risk features for hereditary breast and ovarian cancer (HBOC) and with a previous uninformative result for BRCA1/2 were tested with a panel of 41 genes associated with BC risk. The frequency of pathogenic variants (PVs) was related to the clinical characteristics of BC. (3) Results: We detected a PV rate of 13.5% (excluding two…

Removal of primary tumor improves survival in metastatic breast cancer. Does timing of surgery influence outcomes?
2010
Resection of intact primary tumor is controversial in metastatic breast cancer patients. The aim of this study is to review the impact of surgical resection of primary tumor on overall survival and to assess the role of timing of surgery on survival rates.208 patients with metastatic breast cancer diagnosed between 1982 and 2005 in the Hospital Clinico of Valencia (Spain) were analysed. Exclusion criteria were age80, PS 3-4, Charlson score 3 or follow-up90 days. 123 of these underwent surgery and 85 did not. In order to assess the role of timing, the "surgery" cohort was divided into two sub-groups: "before" (n = 78) or "after" (n = 45) diagnosis of disseminated disease.In the surgery group…
Polymorphisms in TRAIL receptor genes and risk of breast cancer in Spanish women
2007
TRAIL is a potent inducer of apoptosis in malignant but not in normal cells. TRAIL binds to the proapoptotic death receptor DR4 and DR5 as well as to the decoy receptors DcR1 and DcR2. To evaluate the involvement of TRAIL receptor genes in breast cancer, we carried out a case-control study of eight selected polymorphisms in a large sample of Spanish women. Three of the eight selected SNPs (626G/C and 1322G/A in DR4 and 2699A/G in DcR2) showed some evidence of different genotype distributions in a random selection of 535 cases and 480 controls and were therefore studied in our entire sample (1008 cases and 768 controls). For the two DR4 polymorphisms, no differences in genotype or haplotype …
1624P Impact of the COVID-19 pandemic in the cancer fast-track programme
2021
Background: The COVID-19 pandemic has disrupted many aspects of clinical practice in oncology, particularly in making timely cancer diagnosis. Our public health system has been concerned about potential delays leading to a higher proportion of patients with advanced stages. Our cancer diagnosis fast-track program (CFP) in the Clinic-Malvarrosa Health department in Valencia (Spain) is connecting primary care (PC) with different specialists to speed cancer diagnosis and treatment upon well founded suspicion. A 10-year evaluation of our CFP has recently been published. The aim of this analysis was to investigate the impact of the COVID-19 pandemic on the CFP. Methods: We analysed the programme…
