Filter by:Invasive lobular breast carcinoma (ILBC) represents 5-15% of all invasive BCs. The CDH1 gene (OMIM no. 192090), located on the chromosome 16q22.1, encodes for the E-cadherin protein, a key regulator of cell adhesion. Loss of E-cadherin expression is frequently detected in LBC CDH1 germline loss-of-function mutations are associated with the autosomal dominant cancer-predisposition syndrome, hereditary diffuse gastric cancer (HDGC; OMIM no. 137215). The cumulative risk of LBC for women with a CDH1 mutation is estimated to be 42% (95% CI 23% to 68%) by 80 years, when it is a component of HDGC syndrome. Recently, some authors described CDH1 germline mutations in women with in situ or ILBC with early onset (<45 or <50) and bilateral in situ or ILBC with no family history of HDGC. These results are opening a new scenario, suggesting that CDH1 could be a susceptibility gene for LBC in women without a family history of DGC. The first aim of this study is to investigate prevalence of CDH1 in this specific population of women with early onset (<45 or <50) in situ or ILBC, bilateral LBC or LBC with no family history of HDGC.
The purpose of this study is to find out how effective the combination of crizotinib and fulvestrant is in shrinking lobular breast cancer tumours. The investigators will also be assessing the side effects of the combination of crizotinib tablets and fulvestrant injections. The side effects and the doses of crizotinib and fulvestrant have already been evaluated in large clinical trials, but this is the first time these two drugs will be combined together.
This randomized phase III trial studies how well hypofractionated radiation therapy works in preventing recurrence in patients with stage IIa-IIIa cancer who have undergone mastectomy. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells that remain after surgery and have fewer side effects.
A PET scan drop less than 20% in SUVs or below a certain absolute SUV value after the first course of neoadjuvant chemotherapy can predict pathological response, and could in the future lead to an early surgical intervention.
