A few cases with bilateral renal enlargement in acute lymphoblastic leukemia (ALL) are reported in literature. In this article, we report an unusual case of ALL in an adult presenting as multiple lesions in both kidneys and multiple bone lesions.

BACKGROUND AND OBJECTIVES: Bendamustine has been recently approved for the treatment of low-grade lymphoproliferative disorders. There is little data on the effectiveness or toxicity of this drug outside the trial setting. This is the first report on the use of bendamustine from the Indian subcontinent. SETTINGS AND DESIGN: Retrospective descriptive analysis of response and side effects of bendamustine in eight patients with chronic lymphocytic leukemia and eight patients with follicular lymphoma. METHODS: Data was collated from a review of case records. We examined any association between side effects and clinical parameters. RESULTS: The median age of patients was 52 years and three-quarters had received prior treatment with alkylators or fludarabine. Three different protocols of bendamustine were used (single agent, in combination with rituximab or in combination with vincristine and prednisolone). The overall response rate was 80% (47% complete response, 33% partial response, and 20% progressive disease). The drug was well tolerated with very few grade 3/4 toxicities. More than half the patients (9/16) developed a characteristic erythematous, papular skin rash that resolved after completion of chemotherapy. CONCLUSION: Bendamustine is a safe and useful addition to the drug arsenal against lymphoproliferative disorders. A peculiar skin rash was the commonest side effect noted in Indian patients treated with this drug.

Sclerostin domain containing 1 (SOSTDC1) is reportedly down-regulated in various cancers. Our purpose was to study whether epigenetic mechanisms were involved in the down-regulation of expression in gastric cancer. Expression analysis of SOSTDC1 in gastric cancer cell lines indicated mRNA down-regulation. Our reporter assays and gene reactivation studies using 5-aza-2'-deoxycytidine, a DNA demethylating agent, and trichostatin A (TSA), a histone deacetylase (HDAC) inhibitor, demonstrated that epigenetic mechanisms are involved in the down-regulation of SOSTC1 expression. Methylation analysis of the SOSTDC1 promoter CpGs using methylation-specific polymerase chain reaction analysis revealed methylation in gastric cancer cell lines and tissue samples. A majority of tumors (17 of 18) with observed methylation exhibited down-regulation of mRNA expression relative to apparently normal gastric tissues. Immunoreactivity for SOSTDC1 in gastric tumors (24 of 46, 52.1%) was down-regulated relative to normal tissues (36 of 38, 94.7%) (P = 0.00001). The difference in expression between gastric tumor subtypes, intestinal and diffuse, was significant (P = 0.040). Expression of SOSTDC1 in gastric tumors increased the probability of both overall and disease-free survival. When overexpressed in AGS cells, cell proliferation, cell cycle progression, and anchorage-independent growth was repressed. The present findings indicate SOSTDC1 down-regulation involves methylation; SOSTDC1 expression is a potential prognostic factor and tumor suppressor in gastric cancer. © 2013 Elsevier Inc.
