Randomized Controlled Trial
Survival without common toxicity criteria grade 3/4 toxicity for pemetrexed compared with docetaxel in previously treated patients with advanced non-small cell lung cancer (NSCLC): a risk-benefit analysis.
In a recent large phase III study, previously treated patients with advanced non-small cell lung cancer who received pemetrexed demonstrated a survival time similar to patients who received docetaxel (median, 8.3 months with pemetrexed versus 7.9 months with docetaxel), with a more favorable toxicity profile, and significantly fewer Common Toxicity Criteria grade 3/4 toxicities. This is a retrospective risk-benefit analysis of survival without grade 3/4 toxicity, defined as the time to the first occurrence of Common Toxicity Criteria grade 3 or 4 toxicity or death, in the prospective phase III study comparing pemetrexed with docetaxel. ⋯ This analysis of survival without grade 3/4 toxicity suggests a benefit-to-risk profile that favors pemetrexed over docetaxel in the second-line treatment of patients with non-small cell lung cancer.

Primary liposarcomas of the mediastinum are extremely rare neoplasms, comprising less than 1% of all mediastinal tumors. These tumors occur most commonly in the lower extremities (75%) and less frequently in the retroperitoneum. We present a case involving a successful radical resection of a large myxoid liposarcoma and its recurrence, both located in the posterior mediastinum.

Randomized Controlled Trial Multicenter Study Comparative Study
A randomized trial comparing immediate versus delayed treatment of anemia with once-weekly epoetin alfa in patients with non-small cell lung cancer scheduled to receive first-line chemotherapy.
This study evaluated the safety/efficacy of once-weekly (QW) epoetin alfa measured by quality of life (QOL), hemoglobin (Hb), transfusion incidence, tumor response, and survival in patients with chemotherapy-naïve, advanced non-small cell lung cancer (NSCLC). ⋯ Epoetin alfa in subcutaneous doses of 40,000 U QW, given immediately at chemotherapy initiation for advanced NSCLC, was well tolerated, and it effectively maintained Hb, leading to a reduced transfusion incidence versus delayed epoetin alfa. Overall QOL scores were higher than typical in this population, decreasing slightly during treatment in both groups. Overall survival was similar between groups, with no evidence of a negative effect by early epoetin alfa intervention.

Lung cancer remains a leading cause of cancer-related mortality in North America. Despite potentially curative resection, non-small cell lung cancer (NSCLC) patients remain at high risk of relapse and death, with a 5-year survival rate of less than 67%. Several randomized trials now confirm a survival benefit with adjuvant platinum-based chemotherapy seen in the NSCLC Collaborative Group meta-analysis, including the International Adjuvant Lung Trial, National Cancer Institute of Canada BR.10, and Adjuvant Navelbine International Trialist Association (ANITA) trials, with absolute improvements in 4- and 5-year survival rates of 4% to 15%. This study examines whether referral patterns for adjuvant therapy in NSCLC have changed since the presentation of confirmatory trials. ⋯ The presentation of positive adjuvant therapy trials in NSCLC has changed clinical practice substantially, doubling the number of patients with completely resected NSCLC referred for adjuvant chemotherapy since May 2004 (31% versus 63%). Although new evidence to support adjuvant chemotherapy in lung cancer is being disseminated to and accepted by physicians, more patient education and decision support may be required to increase uptake of adjuvant therapy in the early stage NSCLC population.
