ReviewRituximab and its role as maintenance therapy in non-Hodgkin lymphoma.
Since rituximab, a chimeric monoclonal anti-CD20 antibody, was introduced into clinical practice in 1997, data regarding its benefit in terms of response rate, quality of response, progression-free survival and overall survival in B-cell lymphoid malignancies continues to expand. Rituximab has proven to be a relatively well-tolerated drug, with its major side effects being infusion related. ⋯ Subsequently, its use has been extended to include first-line therapy in low-grade lymphoma as well as the treatment of more aggressive histological subtypes such as diffuse large B-cell lymphoma. In this article, we review the landmark trials that have impacted clinical practice in follicular and diffuse large B-cell lymphomas and the emerging data for use of rituximab as maintenance therapy in non-Hodgkin lymphoma.

ReviewSequelae following axillary lymph node dissection for breast cancer.
Axillary lymph node dissection (ALND) has a central role in the surgical management of breast cancer; however, it is associated with a potentially significant morbidity. Although post-ALND complications are often minor, in some cases they can persist for a long time following surgery, thereby affecting the quality of life of breast cancer survivors. Seroma formation and altered sensation of the upper limb are the two most common complications following ALND. ⋯ Major post-ALND complications (such as injury or thrombosis of the axillary vein and injury to the motor nerves of the axilla) are extremely rare. Meticulous surgical technique and careful selection of patients for postoperative radiation therapy are mandatory to prevent significant morbidity following ALND. The introduction of the technique of sentinel lymph node biopsy in clinical practice has resulted in a significant reduction in the incidence of post-ALND complications.

ReviewRecurrent glioblastoma multiforme: advances in treatment and promising drug candidates.
Recurrent glioblastoma multiforme is a lethal disease with currently available treatment options having a limited impact on outcome. In this article, current and novel therapeutic approaches in the treatment of recurrent glioblastoma multiforme, including chemotherapy, targeted molecular agents, virotherapy/gene therapy and immunotherapy and challenges in developing novel therapeutic agents for glioblastoma multiforme will be discussed.

ReviewTemozolomide: a milestone in neuro-oncology and beyond?
Temozolomide (Temodal, Temodar), an imidazol derivative, is a second-generation alkylating agent. The orally available prodrug with the capacity of crossing the blood-brain barrier received accelerated US FDA approval in 1999. Three pivotal Phase II trials showed modest activity in the treatment of recurrent anaplastic astrocytoma glioblastoma. ⋯ Continuous temozolomide administration is associated with profound CD4-selective lymphocytopenia. Molecular studies have suggested that the benefit of temozolomide chemotherapy is restricted to patients whose tumors have a methylated methylguanine methyltransferase gene promotor and are thus unable to repair some of the chemotherapy-induced DNA damage. Temozolomide is under investigation for other disease entities, in particular lower-grade glioma, brain metastases and melanoma.
