Meningeal carcinomatosis (MC) occurs in up to 5% of breast cancer patients. Few studies have evaluated prognostic markers in breast cancer patients with MC. Our aim was to describe the treatment of breast cancer patients with MC, and identify prognostic factors related to survival. Sixty breast cancer patients that had a diagnosis of MC between January 2003 and December 2009 were included. The median age was 46 years (range 27-76). Most patients had invasive ductal carcinoma (78.3%) and high histological/nuclear grade (61.7/53.3%). Estrogen and progesterone receptors were positive in 51.7 and 43.3% of patients, respectively, and 15% were HER-2-positive. Symptoms at presentation were headache, cranial nerve dysfunction, seizures, and intracranial hypertension signals. Diagnosis was made by CSF cytology in 66.7% of cases and by MRI in 71.7%. Intrathecal (IT) chemotherapy was used in 68.3% of patients, and 21.6% received a new systemic treatment (chemo- or hormone therapy). Median survival was 3.3 months (range 0.03-90.4). There was no survival difference according to age, nuclear grade, hormonal and HER-2 status, CSF features, sites of metastasis, systemic and IT chemotherapy, or radiotherapy. However, histological grade and performance status had a significant impact on survival in the multivariate analysis. Only four papers have addressed prognostic factors in breast cancer patients with MC in the last two decades. The results of those reports are discussed here. High histological grade and poor performance status seem to impact survival of breast cancer patients with MC. Prospective studies are necessary to clarify the role of IT and systemic treatment in the treatment of those patients.

Balstilimab elicited promising and durable clinical activity in patients with recurrent/metastatic cervical cancer.• Tumor responses occurred irrespective of tumor PD-L1 status or histology.• Balstilimab is well tolerated, with a safety profile consistent with other PD-1 inhibitors.• These findings highlight balstilimab as an attractive candidate for both single-agent and combination-based immunotherapy.

The involvement of the leptomeninges by metastatic tumors can be observed in solid tumors, in which case it is termed meningeal carcinomatosis (MC), and in lymphoproliferative malignant disease. It is more common in breast and lung cancer, as well as melanoma, with adenocarcinoma being the most frequent histological type. MC is usually a late event, with disseminated and progressive disease already present and, it is characterized by multifocal neurological signs and symptoms. Diagnosis is based on the evaluation of clinical presentation, cerebrospinal fluid and neuroimaging studies. The better systemic disease control is observed with new therapeutic agents, and the development of neuroimaging methods is responsible for the increasing incidence of such metastatic evolution. Intrathecal chemotherapy is generally the treatment of choice, although frequently palliative. Prognosis is guarded, although a higher performance status may indicate a subgroup of patients with a more favorable outcome. Key words: meningeal carcinomatosis, cerebrospinal fluid, meninges, chemotherapy, metastases.Carcinomatose meníngea em tumores sólidos RESUMO O acometimento leptomeníngeo por metástases tumorais pode ocorrer em tumores sólidos, sendo chamado de carcinomatose meníngea (CM), e também em doenças linfoproliferativas. Tumores de mama, pulmão e melanoma são os principais responsáveis pelos casos, e adenocarcinoma é a histologia mais frequentemente encontrada. A CM é um evento tardio na evolução da doença e caracteriza-se por sinais e sintomas neurológicos multifocais. O diagnóstico se faz pela avaliação conjunta do quadro clínico, neuroimagem e estudo do líquido cefalorraquidiano. O maior controle da doença sistêmica obtido com as novas modalidades terapêuticas e a baixa penetração de drogas no sistema nervoso central, aliados ao desenvolvimento nos métodos de neuroimagem observado nas últimas décadas, são fatores que respondem por um aumento na incidência desta apresentação. A quimioterapia intratecal é o tratamento de escolha, porém, frequentemente paliativo. O prognóstico é reservado, sendo que o melhor performance status pode selecionar um subgrupo de pacientes com melhor evolução. Palavras-Chave: carcinomatose meníngea, líquido cefalorraquidiano, meninges, quimioterapia, metástase.

Docetaxel is a new taxoid antineoplastic drug widely used for advanced breast cancer. Skin and nail toxicity are one of the more frequent nonhematologic adverse reactions. Besides dark pigmentations and Beau’s lines, subungual hemorrhage, orange discoloration, acute painful paronychia, onycholysis, subungual hyperkeratosis and transverse loss of the nail plate are described. The type of nail alteration is related with the number of cycles administered and there are no efficacious preventive measures to avoid its development. Clinicians should recognize the clinical picture of these adverse nail reactions because docetaxel is used for several neoplastic disorders.
