Multicenter Study Comparative Study
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.

Randomized Controlled Trial Multicenter Study
Four versus six courses of a dose-escalated cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen plus etoposide (megaCHOEP) and autologous stem cell transplantation: early dose intensity is crucial in treating younger patients with poor prognosis aggressive lymphoma.
Patients with aggressive lymphoma and high-risk features at the time of diagnosis are reported to have a poor prognosis with standard therapy. Attempts to improve the results achieved with the combination of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) using second-generation or third-generation chemotherapy have failed. In the current study, the authors increased the doses and dose intensity of drugs used for the conventional first-line therapy of aggressive lymphoma and designed a Phase II randomized trial that compared four and six courses of dose-escalated CHOP plus etoposide (megaCHOEP) supported by the transplantation of peripheral blood stem cells. ⋯ The results of the current study demonstrate that dose intensity, in particular early dose intensity, significantly influences disease control with high-dose therapy (HDT) and autologous stem cell transplantation. These results also may explain the failure of HDT with low early dose intensity to improve the results obtained with conventional chemotherapy.

Review Case Reports
Successes and failures of the teachable moment: smoking cessation in cancer patients.
Successful cancer treatment can be significantly compromised by continued tobacco use. Because motivation and interest in smoking cessation increase after cancer diagnosis, a window of opportunity exists during which healthcare providers can intervene and assist in the quitting process. ⋯ Despite the importance of stopping smoking for all cancer patients, the diagnosis of cancer is underused as a teachable moment for smoking cessation. More research is needed to empirically test cessation interventions for cancer patients, and attention must be given to complex and unique issues when tailoring cessation treatment to these individuals.

Randomized Controlled Trial
Impact of coping skills intervention with family caregivers of hospice patients with cancer: a randomized clinical trial.
Family caregivers for cancer patients experience high levels of stress and burden and diminished quality of life (QOL). Interventions to improve coping skills of caregivers have been shown to be effective with other populations, but their impact has not been assessed in the difficult context of hospice care. The purpose of this study was to determine whether hospice plus a coping skill training intervention improved family caregivers' QOL, burden, coping, and mastery, compared with hospice plus emotional support, and usual hospice care. ⋯ The coping skills intervention was effective in improving caregiver QOL, reducing burden related to patients' symptoms, and caregiving tasks compared with hospice care alone or hospice plus emotional support. Structured caregiver skill-training interventions for caregivers are promising even in the difficult environment of end-of-life care and for families already receiving benefits of hospice care.
