retinoblastoma/diarrhea

Children with metastatic retinoblastoma are considered to have a poor prognosis after conventional chemotherapy. We used high-dose chemotherapy (HDC) with peripheral hematopoietic stem cell transplantation in such patients in an attempt to improve their survival. Four patients with bone marrow

Purpose To evaluate topotecan-based therapy for advanced intraocular retinoblastoma. Patients and Methods Twenty-seven patients with bilateral retinoblastoma (male patients, n = 14; median age, 8.4 months) received chemotherapy: two courses of topotecan plus vincristine followed by three alternating

Giardiasis is a common cause of diarrhea in undeveloped countries, but is very rare in developed countries. A patient with acute myelogenous leukemia and retinoblastoma presented with a high fever and severe watery diarrhea during induction chemotherapy. On microscopy, cysts were seen in her stool,

OBJECTIVE The aim of this study was to evaluate in an upfront phase II study the response to idarubicin in children with extraocular retinoblastoma. METHODS The starting dose of idarubicin was 15 mg/m(2)/d (days 1 and 2) weeks 0 and 3. After an interim evaluation, the dose was reduced to 10

The majority of hematopoietic malignancies have aberrancies in the retinoblastoma (Rb) pathway. Loss in Rb function is, in most cases, a result of the phosphorylation and inactivation of Rb by the cyclin-dependent kinases (cdks), main regulators of cell cycle progression. Flavopiridol, the first cdk

Transmissible gastroenteritis virus (TGEV), a member of the coronaviridae family, could cause fatal diarrhea of piglets and result in numerous economic losses. Previous studies demonstrated that TGEV infection could lead to mitochondrial damage and upregulate miR-4331 level. So miR-4331 may play an

The majority of human malignancies have aberrancies in the Retinoblastoma (Rb) pathway. Loss in Rb function results from the phosphorylation and inactivation of Rb by the cyclin-dependent kinases (cdks), main regulators of cell cycle progression. Thus, modulators of cdks may have a role in the

Studies to determine the etiology of osteosarcoma involve epidemiologic and environmental factors and genetic impairments. Factors related to patient characteristics include age, gender, ethnicity, growth and height, genetic and familial factors, and preexisting bone abnormalities. Rapidly

Background: The majority of human papillomavirus (HPV)-negative squamous cell carcinoma of the head and neck (SCCHN) present upregulation of the epidermal growth factor receptor (EGFR) and frequent alterations in the cyclin D1-cyclin dependent kinase (CDK) 4/6 (CDK 4/6)-retinoblastoma protein

Aberrations in cell cycle progression occur in the majority of human malignancies. The main pathway affected is the retinoblastoma (Rb) pathway. The tumor suppressor gene Rb is an important component in the G(1)/S transition and its function is abnormal in most human neoplasms. Loss in Rb function

Gossypol has demonstrated in vitro effects on cell cycle regulation and anti-tumor activity against mammary carcinoma cell lines. This Phase I/II study assesses both the effect of gossypol on cell cycle regulatory proteins in vivo and the clinical effect. Twenty women with refractory metastatic

OBJECTIVE Flavopiridol is primarily a cyclin-dependent kinase-9 inhibitor, and we performed a dose escalation trial to determine the maximum tolerated dose and safety and generate a pharmacokinetic (PK) profile. METHODS Patients with a diagnosis of relapsed myeloma after at least two prior
