Randomized Controlled Trial Multicenter Study Comparative Study
Phase III trial of two investigational schedules of ifosfamide compared with standard-dose doxorubicin in advanced or metastatic soft tissue sarcoma: a European Organisation for Research and Treatment of Cancer Soft Tissue and Bone Sarcoma Group Study.
Single-agent doxorubicin remains the standard treatment for advanced soft tissue sarcomas. Combining doxorubicin with standard-dose ifosfamide has not been shown to improve survival and is associated with a significantly increased toxicity; it is not known whether higher dose single-agent ifosfamide is superior to doxorubicin. ⋯ Single-agent doxorubicin remains the treatment of choice for patients with advanced soft tissue sarcoma.

To study whether changes of [18F]fluorodeoxyglucose positron emission tomography (FDG-PET) during treatment correlate with post-treatment responses in tumor and normal lung in patients with non-small-cell lung cancer (NSCLC). ⋯ This pilot study suggests a significant correlation in tumor metabolic response and no association in lung FDG activity between during RT scans and 3 months post-RT scans in patients with NSCLC. Additional study with a large number of patients is needed to validate these findings.

Randomized Controlled Trial Multicenter Study
Randomized trial of laparoscopic-assisted resection of colorectal carcinoma: 3-year results of the UK MRC CLASICC Trial Group.
The aim of the current study is to report the long-term outcomes after laparoscopic-assisted surgery compared with conventional open surgery within the context of the UK MRC CLASICC trial. Results from randomized trials have indicated that laparoscopic surgery for colon cancer is as effective as open surgery in the short term. Few data are available on rectal cancer, and long-term data on survival and recurrence are now required. ⋯ Successful laparoscopic-assisted surgery for colon cancer is as effective as open surgery in terms of oncological outcomes and preservation of QoL. Long-term outcomes for patients with rectal cancer were similar in those undergoing abdominoperineal resection and AR, and support the continued use of laparoscopic surgery in these patients.

Randomized Controlled Trial
Quantitative measurement of epidermal growth factor receptor is a negative predictive factor for tamoxifen response in hormone receptor positive premenopausal breast cancer.
Although there is evidence for interaction between epidermal growth factor receptor (EGFR) and estrogen receptor (ER), it is still not clear how this affects response to endocrine therapies like tamoxifen. Here we assess the relationship between EGFR expression and tamoxifen response, with a new quantitative technology. ⋯ This study provides clinical evidence that confirms the basic work that has shown high EGFR can indicate resistance to tamoxifen. It suggests that careful measurement of EGFR protein expression might define a subset of low-stage patients that could benefit from an alternative therapy.

To evaluate the outcome of patients with limited-stage small-cell lung cancer (L-SCLC) treated with cisplatin and etoposide (PE), early prophylactic cranial irradiation (PCI), and high-dose twice-daily thoracic radiotherapy (bid RT). ⋯ This regimen included a high total dose of bid TRT, which resulted in a favorable 5-year survival rate. Local failure remains a problem that will require additional investigation. Newer technology should allow the safe administration of greater doses of RT, which should improve patient outcome. Data from eight trials were combined to demonstrate a relationship between RT dose fractionation and 5-year survival.
