The role for completion axillary dissection (CLND) in patients with breast cancer who have tumor-positive sentinel lymph nodes (SLN) has been questioned. The objective of this study was to examine the long-term safety of avoiding CLND in selected patients with positive SLNs. ⋯ In selected patients who had positive SLNs, the locoregional failure rate was low without CLND. Prospective studies will be valuable to corroborate these results and to refine further the optimal selection criteria for this approach.

Efficacy and safety of imatinib in patients with chronic myeloid leukemia and complete or near-complete cytogenetic response to interferon-alpha.
Interferon-alpha (IFN-alpha) confers a survival advantage for the minority of patients with chronic myeloid leukemia (CML) who achieve a complete cytogenetic response. The question of whether IFN-alpha-responsive patients can experience further improvements with imatinib has not been answered. Imatinib offers clear quality of life advantages. Furthermore, patients who achieve a major molecular response (MMR) while receiving imatinib are likely to remain progression free. ⋯ These data suggest that switching IFN-alpha-responsive patients to imatinib leads to a rapid improvement in achieving an MMR, a response with established prognostic value, and is well tolerated. The study should help patients and their physicians make evidence-based decisions regarding the potential benefits and risks of switching to imatinib.

The objective of this retrospective cohort study was to define the efficacy and safety of fractionated radiotherapy (FRT) and stereotactic radiosurgery (SRS) for the treatment of patients with pituitary adenoma. ⋯ Both FRT and SRS were efficient treatment modalities for the control of tumor growth in patients with pituitary adenomas. The current results indicated that single-dose radiosurgery more promptly produces an effect on the hypersecretion of pituitary hormones and may be recommended over FRT for suitable patients.

Chemotherapy-induced nausea and vomiting (CINV) is among the most feared side effects of cancer treatment. Poorly controlled CINV may lead to additional office visits or emergency room admissions, thus increasing the overall costs of cancer care. The objective of the project was to estimate the societal costs of uncontrolled CINV among working-age cancer patients. ⋯ Despite a prevalent use of the 5-HT(3) receptor antagonists, uncontrolled CINV remained a common and costly problem among cancer patients treated with highly or moderately emetogenic chemotherapy.

To determine the effects of preoperative exercise training on cardiorespiratory fitness in patients undergoing thoracic surgery for malignant lung lesions. ⋯ Preoperative exercise training is a beneficial intervention to improve cardiorespiratory fitness in patients undergoing pulmonary resection. This benefit may have important implications for surgical outcome and postsurgical recovery in this population. Larger randomized controlled trials are warranted.
