Value of precise localization of recurrent multiple myeloma with F-18 FDG PET/CT.

A 37-year-old man with multiple myeloma in remission underwent routine fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) study for disease restaging. Both FDG-PET and CT images showed focal abnormalities in the region of the T6 vertebra, but the fused images that are routinely provided with PET/CT could precisely localize the FDG active lesion to a soft tissue focus in the epidural space, away from a lytic nonactive vertebral body lesion despite their close proximity. The PET/CT scan identified a few other metabolically active osseous lesions out of many lytic bony changes throughout the skeleton.

Isolation of specific and biologically active peptides that bind cells from patients with acute myeloid leukemia (AML).

Purpose: In a departure from conventional strategies to improve treatment outcome for myeloid malignancies, we report the isolation of leukemia-specific peptides using a phage display library screened with freshly obtained human myeloid leukemia cells.

Results: A phage display library was screened by 5 rounds of biopanning with freshly isolated human AML cells. Individual colonies were randomly picked and after purification, biologic activity (growth and differentiation) on fresh AML cells was profiled.

Psychiatric assessment and symptom management in elderly cancer patients.

The number of older adults in the general population continues to grow. As their numbers rise, the elderly and the management of their medical problems must be of increasing concern for health-care professionals. Within this older population, cancer is a leading cause of morbidity and mortality.

The distinctive role of positron emission tomography/computed tomography in breast carcinoma with brown adipose tissue 2-fluoro-2-deoxy-d-glucose uptake.

The diagnostic power of an integrated positron emission tomography/computed tomography (PET/CT) system for whole-body 2-fluoro-2-deoxy-d-glucose (FDG) imaging is clearly demonstrated in this case report. The precise anatomic localization of FDG uptake with CT in a PET/CT scan of a patient with known breast carcinoma helped identify a contralateral breast tumor with axillary lymph node metastasis despite the presence of extensive physiologic brown fat FDG uptake. Accordingly, the patient received appropriate surgical management and pathologic confirmation of the disease.

Role of post-operative chemoradiation in resected gastric cancer.

The curative management of gastric adenocarcinoma depends upon complete resection of the primary tumor. In patients with lymph node metastases in the resected specimen, the relapse and death rates from recurrent cancer are at least 70%-80%. There is continued debate over whether more extensive lymph node dissection (D2) improves survival when compared to less extensive operations.

Treatment of localized gastric cancer.

The curative management of gastric adenocarcinoma depends upon complete resection of the primary tumor. In patients with lymph node metastases in the resected specimen, the relapse and death rates from recurrent cancer are at least 70% to 80%.

Nephrotic proteinuria associated with high-dose pamidronate in multiple myeloma.

Five patients receiving increased dose or frequency of pamidronate beyond the recommended dose (90 mg/monthly) exhibited nephrotic proteinuria (range 3.96-24 g/24 h). On dose reduction or discontinuation, three of these patients showed decreased proteinuria to normal levels (< 1 g/24 h), and proteinuria decreased to 4.

Waldenström's macroglobulinaemia: current therapy and future approaches.

Waldenström's macroglobulinaemia is a rare B-cell malignancy. It is prevalent in the sixth and seventh decades, the median age at diagnosis being 63 years. Conventional treatment has involved alkylator therapy, especially chlorambucil given daily at a low dose or intermittently at a higher dose.

Therapeutic dilemmas with thalidomide in multiple myeloma: case discussions.

Three cases of multiple myeloma treated with thalidomide are presented which highlight therapeutic dilemmas presented by therapy with this new agent. The difficulty of stem cell collection during thalidomide therapy is illustrated. The question of continuation of thalidomide after attainment of a plateau or remission is discussed and the management of neuropathy considered.

Radiation therapy for age-related macular degeneration.

Neovascular age-related macular degeneration is the most common cause of severe irreversible blindness in the Western world in people older than age 50. Laser photocoagulation is the only proven treatment for this disease; however, fewer than 20% of patients are eligible for this treatment because the majority of choroidal neovascularization membranes are not visible by ophthalmoscopy or angiography. In addition, many patients elect not to undergo this treatment because laser treatment of subfoveal neovascular membranes results in immediate and permanent central visual loss.
