To the authors' knowledge there is little information available regarding the effectiveness of standard antiemetic therapy among cancer patients who receive emetogenic chemotherapy in clinical practice, especially in the pediatric population. The current study was undertaken to determine the effectiveness of standard antiemetic interventions among children receiving emetogenic chemotherapy. ⋯ Nausea and emesis remain significant problems among children who receive emetogenic chemotherapy. CP rates were associated significantly with patient age, and higher rates were observed among very young children.

Prostate carcinoma (PCa) is one of the most common malignancies in men. Androgen-deprivation therapy (ADT) is used frequently in the treatment of recurrent and metastatic PCa, rendering these men hypogonadal. Because male hypogonadism is associated with an unfavorable metabolic profile, and men with PCa have high cardiovascular mortality, the authors evaluated the effects of long-term ADT on fasting glucose levels, insulin levels, and insulin resistance. ⋯ The current data suggested that men with PCa who are receiving long-term ADT are at risk for developing insulin resistance and hyperglycemia, thus leading to their increased risk of cardiovascular disease. This adverse metabolic profile developed independent of age and BMI and appeared to be a direct result of androgen deprivation.

Detection of stool DNA mutations before and after treatment of colorectal neoplasia.
Whether stool DNA abnormalities arise solely from colorectal neoplastic lesions or are due to more pervasive field effects is not known. In the current study, the authors conducted a prospective multicenter study to evaluate the performance of stool-based DNA testing in a large cohort and to examine whether the findings before treatment persist after surgical resection and/or adjuvant therapy. ⋯ Although many samples collected 1-3 months after surgical resection of the colorectal neoplasm tested positive on the MTAP, most were negative by 6-9 months, indicating that stool DNA abnormalities disappear after treatment of the neoplastic lesions. Surgery and chemoradiation appear to induce transient DIA abnormalities that may be independent of the presence of neoplasia.

Advanced breast carcinoma almost always leads to a malignant pleural effusion, conditioning the performance status of patients and consequently quality of life. The treatment of malignant pleural effusion should be a priority in the management of such patients. The results of video-thoracoscopic approach (VATS) chemical pleurodesis was analyzed in patients with recurrent pleural effusion from breast carcinoma. ⋯ Talc pleurodesis via VATS is an effective and safe procedure that yields a high rate of success at the first attempt and achieves long-term control of malignant pleural effusion due to breast carcinoma. Concomitant biopsies performed during the VATS procedure were a determining factor in the subsequent decision-making process.

The clinical features of ipsilateral breast tumor recurrence (IBTR) after breast conserving therapy (BCT) for early stage breast cancer were analyzed from long-term follow-up of BCT in Japan. The purpose of this study was to clarify risk factors of IBTR and the impact of IBTR on development of distant metastases in this ethnic group. ⋯ Young age, positive surgical margin, and omission of radiation therapy seemed to be important factors in relation to local control. The authors' results also indicated that IBTR is significantly associated with subsequent distant metastasis. Patients with positive nodal status at primary operation or with short interval from primary operation to IBTR are at especially high risk of distant metastasis. It remains unclear, however, whether IBTR is an indicator or a cause of subsequent distant metastases.
