To conduct a dose-escalation trial of rituximab in patients with chronic lymphocytic leukemia (CLL) to define the maximum-tolerated dose (MTD), to evaluate first-dose reactions in patients with high circulating lymphocyte counts, and to assess the efficacy at higher versus lower doses. ⋯ Rituximab has significant activity in patients with CLL at the higher dose levels. Severe first-dose reactions were uncommon in patients with CLL, even with high circulating lymphocyte counts, but were frequent in patients with other mature B-cell leukemias in which CD20 surface expression is increased. Efficacy of rituximab was also significant in this group of patients.

Randomized Controlled Trial Clinical Trial
Individualized patient education and coaching to improve pain control among cancer outpatients.
An estimated 42% of cancer patients suffer from poorly controlled pain, in part because of patient-related barriers to pain control. The objective of this study was to evaluate the effect of an individualized education and coaching intervention on pain outcomes and pain-related knowledge among outpatients with cancer-related pain. ⋯ Compared with provision of standard educational materials and counseling, a brief individualized education and coaching intervention for outpatients with cancer-related pain was associated with improvement in average pain levels. Larger studies are needed to validate these effects and elucidate their mechanisms.

Clinical Trial
Phase I clinical and pharmacokinetic study of rebeccamycin analog NSC 655649 given daily for five consecutive days.
Rebeccamycin analog (NSC 655649) is active against a variety of both solid and nonsolid tumor cell lines. We performed a phase I trial to determine the maximum-tolerated dose (MTD) of rebeccamycin analog when given on a daily x 5 schedule repeated every 3 weeks, characterize the toxicity profile using this schedule, observe patients for antitumor response, and determine the pharmacokinetics of the agent and pharmacodynamic interactions. ⋯ The recommended phase II dose for NSC 665649 on a daily x 5 every 3 weeks schedule is 141 and 165 mg/m(2)/d for patients with prior and no prior therapy, respectively, with DLT being neutropenia. During this phase I trial, encouraging antitumor activity was been observed.

Rituximab has been reported to have little activity in small lymphocytic lymphoma (SLL)/chronic lymphocytic leukemia (CLL) and to be associated with significant infusion-related toxicity. This study sought to decrease the initial toxicity and optimize the pharmacokinetics with an alternative treatment schedule. ⋯ Rituximab administered thrice weekly for 4 weeks demonstrates clinical efficacy and acceptable toxicity. Initial infusion-related events seem to be cytokine mediated and resolve by the third infusion making rapid administration possible. Future combination studies of rituximab with other therapies in CLL seem warranted.

To evaluate therapeutic options for recurrent malignant sacrococcygeal germ cell tumors (GCT) following three-agent, cisplatinum-based, first-line chemotherapy and tumor resection. ⋯ The complete resection of the local recurrence represents the cornerstone of salvage treatment. Preoperative platinum-based chemotherapy, combined with RHT in some patients, facilitates complete tumor resection. Radiotherapy should be reserved for those patients with microscopically incomplete tumor resection. As the chance of cure decreases with further relapses, it is important to establish a stringent therapeutic strategy to avoid significant treatment delays and, most importantly, insufficient local therapy.
