Exploring the psychosocial morbidity of women undergoing chemotherapy for breast cancer in a post-war setting: experiences of Northern Sri Lankan women.

Purpose: A breast cancer diagnosis leads to considerable internal conflict and social disruption. Coping with breast cancer may be especially challenging where psychosocial services are not integrated to cancer care. This exploratory descriptive qualitative study delves into breast cancer-associated psychosocial morbidity among women diagnosed with breast cancer at a cancer centre in post-war northern Sri Lanka.

Breaking Bad News in Ethnic Settings: Perspectives of Patients and Families in Northern Sri Lanka.

Purpose: The discussion of a cancer diagnosis and prognosis often is difficult. This study explored the expectations of Tamil-speaking patients with cancer and their families with respect to receiving their cancer diagnosis in northern Sri Lanka.

Methods: This exploratory, descriptive, qualitative study used semistructured interviews.

Epitope distance to the target cell membrane and antigen size determine the potency of T cell-mediated lysis by BiTE antibodies specific for a large melanoma surface antigen.

Melanoma chondroitin sulfate proteoglycan (MCSP; also called CSPG4, NG2, HMW-MAA, MSK16, MCSPG, MEL-CSPG, or gp240) is a surface antigen frequently expressed on human melanoma cells, which is involved in cell adhesion, invasion and spreading, angiogenesis, complement inhibition, and signaling. MCSP has therefore been frequently selected as target antigen for development of antibody- and vaccine-based therapeutic approaches. We have here used a large panel of monoclonal antibodies against human MCSP for generation of single-chain MCSP/CD3-bispecific antibodies of the BiTE (for bispecific T cell engager) class.

Human IgG1 antibodies antagonizing activating receptor NKG2D on natural killer cells.

NKG2D is a surface receptor expressed on NK cells but also on CD8(+) T cells, gammadelta T cells, and auto-reactive CD4(+)/CD28(-) T cells of patients with rheumatoid arthritis. Various studies suggested that NKG2D plays a critical role in autoimmune diseases, e.g.

CD19-/CD3-bispecific antibody of the BiTE class is far superior to tandem diabody with respect to redirected tumor cell lysis.

Many kinds of bispecific antibodies recruiting T cells for cancer therapy have been developed. Side-by-side comparison has shown that CD19-/CD3-bispecific antibodies of the diabody, tandem diabody (Tandab) and quadroma format had similar cytotoxic activity, with Tandab being the most active format. Tandab has also been claimed to be superior to single-chain (sc) Fv-based bispecific constructs although data from a side-by-side comparison are not available.
