Obtaining a major (Philadelphia chromosome [Ph] of < 35%) or a complete cytogenetic response (Ph of 0%) has been associated with excellent long-term survival. Cytogenetic response may continue to improve with therapy. Because early allogeneic stem cell transplantation (SCT) may be associated with a better outcome, early parameters predicting for subsequent cytogenetic responses would optimize the treatment decision-making. ⋯ Patients with Ph-positive, chronic-phase CML who have persistent 100% Ph-positive disease after > or = 6 months of imatinib mesylate therapy may be offered allogeneic SCT or considered for alternative investigational therapies.

Randomized Controlled Trial Multicenter Study Clinical Trial
Establishing the dose of the oral NK1 antagonist aprepitant for the prevention of chemotherapy-induced nausea and vomiting.
The neurokinin-1 antagonist aprepitant (EMEND; Merck Research Laboratories, West Point, PA) has been shown to reduce chemotherapy-induced nausea and vomiting when it is given with a 5-hydroxytryptamine-3 receptor antagonist and dexamethasone. The current study sought to define the most appropriate dose regimen of oral aprepitant. ⋯ When it was added to a standard regimen of intravenous ondansetron and oral dexamethasone in the current study, aprepitant reduced chemotherapy-induced nausea and vomiting and was generally well tolerated, although increases in infection were noted that were assumed to be due to elevated dexamethasone levels as a result of the pharmacokinetic interaction. The aprepitant 125/80-mg regimen had the most favorable benefit:risk profile.

Multicenter Study
Conservative management of Paget disease of the breast with radiotherapy: 10- and 15-year results.
At 5-year follow-up, patients with Paget disease of the breast who were treated with breast-conserving surgery (BCS) and radiotherapy (RT) had excellent results. The current report provides 10- and 15-year rates of tumor control in the breast, as well as disease-free and overall survival rates following BCS and RT in a cohort of patients with Paget disease presenting without a palpable mass or mammographic density. ⋯ These data confirm excellent rates of local control, disease-free survival, and overall survival at 10 and 15 years following BCS and RT for Paget disease of the breast. This study continues to support the recommendation of local excision and definitive breast irradiation as an alternative to mastectomy in the treatment of patients with Paget disease presenting without a palpable mass or mammographic density.

Comparative Study
Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue of the head and neck area: high rate of disease recurrence following local therapy.
Mucosa-associated lymphoid tissue (MALT) lymphoma is a distinct entity with specific clinical and pathologic features that may affect diverse organs. MALT-lymphomas remain localized within their original environment for a long period of time. As recent data have demonstrated a relatively high rate of multiorgan involvement at diagnosis, the authors have retrospectively evaluated 36 patients presenting with MALT-lymphoma in the head and neck area. The authors focused on patients' disease localization, initial treatment, clinical course, and follow-up. ⋯ These data suggest that MALT-lymphomas of the head and neck area are preferentially treated using local modalities such as radiation and/or resection. This practice, however, is associated with an unexpectedly high rate of dissemination or disease recurrence. Obtaining an initial complete response is crucial in these patients. According to previous data, the possibility of understaging in such patients cannot be ruled out. Clinical trials with application of systemic treatment are warranted for these patients.
