Multiple myeloma (MM) is a deadly, incurable malignancy in which antibody-secreting plasma cells (PCs) become neoplastic. Previous studies have shown that the PC niche plays a role cancer progression. Bone marrow (BM) cores from MM and a premalignant condition known as monoclonal gammopathy of unknown significance (MGUS) patients were analyzed with confocal and transmission electron microscopy. The BM aspirates from these patients were used to generate 3D PC cultures. These in vitro cultures were then assayed for the molecular, cellular, and ultrastructural hallmarks of dysfunctional PC at days 1 and 5. In vivo, evidence of PC endoplasmic reticulum stress was found in both MM and MGUS BM; however, evidence of PC autophagy was found only in MM BM. Analysis of in vitro cultures found that MM PC can survive and maintain a differentiated phenotype over an unprecedented 5 days, had higher levels of paraprotein production when compared to MGUS-derived cultures, and showed evidence of PC autophagy as well. Increased fibronectin deposition around PC associated with disease severity and autophagy dysregulation was also observed. 3D cultures constructed from BM aspirates from MGUS and MM patients allow for long-term culture of functional PC while maintaining their distinct morphological phenotypes.

We described a rare case of multiple myeloma in a 60-year-old man, in whom relapse limited to the irradiated area in the left lobe of the liver developed following radiotherapy for lesions in 11th and 12th thoracic spines. Immunohistochemical analysis revealed expression of hepatocyte growth factor (HGF) and hepatocyte growth factor receptor (c-Met) in the hepatocytes in the irradiated area of the liver. We speculate that the malignant plasma cells might have proliferated in response to local increase of HGF production in the irradiated liver. The role of HGF in the extraosseous spread of multiple myeloma and also under the experimental condition of hepatic transplantation is discussed.

The incidence of most haematological malignancies increases with age. Given that those aged >65 years represent the fastest growing segment of Western populations, these cancers may commonly present to medical teams with an interest in older patients. Over the last 20 years there have been dramatic improvements in the outlook for patients diagnosed with haematological cancers, but there is evidence that many of these improvements have been restricted to younger patients. It is therefore important that older patients with haematological malignancies are rapidly diagnosed and promptly treated with the best available therapies. Clinical trials that specifically encompass older patients are clearly important. In this review, the presentation and management of common haematological malignancies will be discussed, including myelodysplasia, acute leukaemia, lymphoproliferative disorders and myeloma.

Objective: The study was conducted to understand the emotional impact of multiple myeloma, as well as the impact of its principle treatment, peripheral blood stem cell transplant (PBSCT). The absence of psycho-oncology research literature on this population prompted the need for a hypothesis-generating investigation. Thus, a qualitative design was used to construct a theoretical model of the trauma relating to diagnosis and treatment of myeloma. The study also incorporates the important period of reflection and growth following treatment.

Methods: The sample consisted of 3 women and 3 men treated for myeloma at a New York City-based cancer treatment center. Data from individual interviews were audiotaped and transcribed. After extensive review, the data were categorized into groups of repeating ideas, themes and broad theoretical constructs.

Results: A five-construct model emerged from the data analysis that integrated a model of trauma and growth presented in earlier work (Auerbach et al., 2006). These constructs roughly correspond with stages of illness, but do not necessarily imply a linear process, as suggested by stage models. The first construct is diagnosis. Patients receive the news that they have multiple myeloma. Initial reactions are discussed and a treatment plan takes form. In the second construct, treatment, patients highlight the physical and emotional hurdles confronted throughout treatment. The third construct, network of safety, presents social factors that play a role in comforting patients throughout illness. Patients recognize the importance of a strong support system during their experiences. In the fourth construct, recuperation, physical energy is regained after an arduous recovery period. This contributes to higher spirits and a motivation to reengage with life. The fifth construct is reflection and new existence. Patients strive to balance a new reality that relapse and death are inevitable, along with their need to live a meaningful life. Many do not yet appreciate how their disease has impacted them, but describe how their interpersonal lives and perceptions have changed, both positively and negatively.

Significance of results: Limitations of the study, future directions for research and clinical implications are discussed.
