Ki-67 is a prognostic marker for hormone receptor positive tumors.

PURPOSE: To evaluate the utility of Ki67 as a prognostic marker in Luminal B node-negative breast cancer patients. METHODS: We identified 888 patients with invasive breast carcinomas who underwent surgery between 1997 and 2004. Several classical factors were collected: age, tumor size, node involvement, tumor grade, estrogen and progesterone receptors, HER2 and Ki-67 expression. We analyzed if these parameters could be considered as a prognostic factor. In early Luminal B group, we investigated which of the following biological features provide information about bad prognosis: lack of progesterone receptor expression, HER2 overexpression/amplification or high Ki-67 value. RESULTS: The majority of patients were alive and without relapse of tumor at the moment of the analysis (70 %). The prognostic factors founded in multivariate analysis were: tumor size, node involvement, grade 3 and Ki-67 expression. When we stratified the sample by immunohistochemistry (IHC) in tumor subtypes, we assessed 680 patients and we observed 191 Luminal B tumors. The biological parameter related to the worst survival in absence of nodal involvement was Ki-67 value. CONCLUSIONS: Ki-67 represents an additional predictor of survival in Luminal B node negative breast cancer. Conversely, neither Progesterone-receptor nor HER2 status proved prognostic significance in this group in our study.

SEOM guide to antiemetic prophylaxis in cancer patients treated with chemotherapy 2013.

Chemotherapy-induced emesis (CIE) both in the form of nausea and vomiting is one of the adverse effects most feared by patients who receive treatment, and one of the factors that most affect their quality of life and limit their functional capacity for everyday activities. Chemotherapy-induced emesis can result from many factors, depending on the treatment and the patients themselves. The best treatment for CIE is prevention, based on the use of drugs aimed at inhibiting the signal of certain neurotransmitters involved in the process. Antiemetic prophylaxis for chemotherapy of high-emetogenous potential lasting 1 day includes a combination of anti-5-HT3, neurokinin-1 inhibitors and dexamethasone. Antiemetic prophylaxis for chemotherapy of moderate-emetogenous potential lasting 1 day includes a combination of palonosetron and dexamethasone. Prophylaxis is not recommended for chemotherapy with minimal emetogenous potential. In the case of unforeseen or refractory emesis the use of olanzapine, metoclopramide or phenothiazine should be considered.

[Prostate adenocarcinoma and synchcronous multiple myeloma: a case report]. / Adenocarcinoma prostático y mieloma múltiple sincrónicos: a propósito de un caso.

PURPOSE: To report a case of synchronous prostatic cancer with multiple myeloma as inusual neoplasm presentation. To indicate the clinical data that they help to suspect the myeloma presence in the prostate bone metastatic disease. CASE REPORT: Patient 63 years old diagnosed of prostatic carcinoma with bone metastasis and BAC good responsive, who have clinical deterioration, hypercalcemia and renal insufficiency. RESULTS: The presacred mass biopsy and extension study to find one second tumour (myeloma). CONCLUSION: The presence of multiple myeloma must be to rule out when there are bone lytics injuries, well biochemical evolution with therapy and clinical deterioration, hypercalcemia and quickly progressive renal insufficiency.
