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.

Nipple aspirate fluid (NAF) cytology is a simple noninvasive method to study cells exfoliated into the ductal system of the breast. In the current study, the significance of cytologic findings in NAF was determined by correlating them with histopathologic findings from corresponding breast tissue. Cytologic-histologic correlations of NAF were performed in only a few studies. ⋯ The probability of detecting malignant cells in NAF is dependent on the extent of DCIS and nipple involvement by DCIS. Nipple aspirate fluid is not a sensitive test for detecting invasive carcinoma of the breast. Atypical cytology in NAF is associated with papillary lesions in the underlying breast.

Clinical Trial
Phase I study of temozolomide and escalating doses of oral etoposide for adults with recurrent malignant glioma.
Although temozolomide is active against recurrent malignant glioma, responses in many patients are modest and short-lived. Temozolomide may prove more effective in combination with other agents. Therefore, combination oral chemotherapy for these patients is a particularly attractive approach. ⋯ The maximum tolerated dose of temozolomide and oral VP-16 in this heavily treated group of patients with recurrent malignant glioma is temozolomide 150 mg/m(2) per day for 5 days and oral VP-16 50 mg/m(2) per day for 12 days.

Predicting outcome for men with clinically localized prostate carcinoma treated with curative intent remains imprecise and further evaluation of accepted and potential predictive factors is needed. ⋯ This study demonstrated that the proportion of prostate biopsy cores containing tumor is an independent predictor of outcome after subsequent radical prostatectomy and suggested that perineural invasion has a predictive role in patients with a preoperative PSA > 10 ng/ml.

The objective of this study was to clarify the prognostic and predictive value of immunoreactivity for the cyclin-dependent kinase inhibitor p27(Kip1) in patients with early-stage breast carcinoma and to investigate its relation with clinicopathologic features and other markers. ⋯ This analysis indicates that p27 immunoreactivity has little if any prognostic value in patients with early-stage breast carcinoma. However, these findings suggest that, in patients with breast carcinoma who have negative lymph node status, reduced p27 immunoreactivity is associated with HER-2/neu overexpression and may be predictive of a benefit from the early administration of adjuvant chemotherapy.
