Overview of recent trends in diagnosis and management of leptomeningeal multiple myeloma.

Neurological complications related to multiple myeloma (MM) are not uncommon; however, direct involvement of the central nervous system (CNS) is extremely rare and represents a diagnostic and therapeutic challenge. Significant survival difference has been noted with the introduction of novel therapy in patients with MM, but their effect on the incidence and their use for management of leptomeningeal myeloma (LMM) is uncertain. Analysis of published data demonstrates its recent increased incidence, median time to CNS presentation, and slight improvement in median survival after diagnosis of LMM. Less common MM isotypes have been overrepresented in LMM. CNS relapse occurred mostly in patients with Durie-Salmon stage III MM. Despite treatments, standard or experimental, the survival rates of LMM remain dismal. Monitoring high risk patients closely, even after achieving complete remission, may be useful in early detection of LMM. As we gain better understanding of LMM, we recommend that future research and clinical care focus on earlier diagnosis and development of more efficient CNS-directed therapy to improve survival in this patient population.

Simultaneous presentation of pancreatic cancer in a genetically unrelated couple.

Patients with pancreatic cancer tend to have a poor prognosis despite aggressive treatment, and their 5-year overall survival rate remains dismal. Several risk factors could potentially trigger the development of pancreatic cancer but many of them identified so far have been only weakly linked. Occurrence of pancreatic cancer in a husband and wife around the same time in the same household even when exposed to similar environmental factors is rare. Although familial pancreatic cancer is a known entity, pancreatic cancer in genetically unrelated married couples has not been studied. Here we present such a scenario involving one couple. In this case report, we discuss the chronological events leading to pancreatic cancer in a genetically unrelated married couple and the risk factors that may have led to cancer, in addition to exploring the possible links.

Low-dose ruxolitinib for improving leukopaenia and reducing recurrent infections associated with myelofibrosis.

Myelofibrosis, either primary or resulting from essential thrombocythemia or polycythemia vera, may present with highly variable white blood cell counts, including progressive leukopaenia with its associated risk of infections. Medications have been developed to reduce splenomegaly and other symptoms, but there are no reports of improved white blood cell counts. We report a case of primary myelofibrosis with marked improvement in leukopaenia and reduced recurrent infections, in addition to reduction in spleen size and improvement in disease-associated symptoms, within 20 weeks after using low-dose ruxolitinib. Although reduction of splenomegaly in myelofibrosis patients is the anticipated benefit of ruxolitinib, the drug may also have the potential to improve leukopaenia if used at a low dose.
