Systemic intravenous chemotherapeutic agents can cause multiple emergency situations including acute and chronic local and systemic reactions. Amongst them, drug extravasation is one of the most devastating complications, as many drugs can cause varying degrees of local tissue injury when extravasated. ⋯ The proper maintenance of intravenous lines, application of local cooling or warming for certain extravasations, and the use of antidotes to prevent the local toxic action of the extravasated drugs are the basis of medical management. The specific antidotes for certain chemotherapeutic agents are also discussed in this article.

TZT-1027 is a synthetic dolastatin 10 analog with antineoplastic properties in various cell lines and tumor xenografts. The purpose of this phase I study was to evaluate the safety and toxicity, maximum tolerated dose, pharmacokinetics and pharmacodynamics, clinical and metabolic antitumor activity of TZT-1027 when given as a 1-h intravenous infusion every 3 weeks in patients with refractory solid tumors. ⋯ The recommended dose of TZT-1027 for the 3-weekly administration is 2.7 mg/m(2). Neutropenia, fatigue and a reversible peripheral neurotoxic syndrome are dose-limiting with this schedule. TZT-1027 may be associated with neurological side-effects in patients previously exposed to neurotoxic compounds such as oxaliplatin.

In advanced metastatic colorectal adenocarcinoma, the addition of a neo-adjuvant systemic treatment to surgery might translate into a survival advantage, although this is yet to be confirmed by ongoing randomized trials. The objective of this study was to assess the effects of preoperative systemic chemotherapy on the morphology of non-tumoral liver. ⋯ Systemic neo-adjuvant chemotherapy in metastatic colorectal cancer frequently causes morphological lesions involving hepatic microvasculature. Sinusoidal obstruction, complicated by perisinusoidal fibrosis and veno-occlusive lesion of the non-tumoral liver revealed by this study, should be included in the list of the adverse side-effects of colorectal systemic chemotherapy, in particular related to the use of oxaliplatin.

Multicenter Study
The impact of delayed chemotherapy-induced nausea and vomiting on patients, health resource utilization and costs in German cancer centers.
Delayed chemotherapy-induced nausea and vomiting (CINV) remains a major adverse effect of cancer chemotherapy. We assessed, under current practice patterns, the occurrence and impact on healthcare resource utilization of CINV in patients receiving emetogenic chemotherapy. An additional aim of this study was to estimate costs imputable to CINV in the German healthcare environment. ⋯ A substantial proportion of patients continue to experience CINV. This entails not only clinical but also economic consequences, and highlights a continuing need for improved utilization of existing antiemetic agents and for new, more efficacious treatments. The greatest improvements in patient care and potential for cost offset may be realized by preventing delayed CINV.

Review Comparative Study
Dysphagia following chemoradiation for locally advanced head and neck cancer.
To assess the prevalence, severity and morbidity of dysphagia following concurrent chemoradiation for head and neck cancer. ⋯ Dysphagia is a common, debilitating and potentially life-threatening sequela of concurrent chemoradiation for head and neck malignancy. Physicians should be aware that the clinical manifestations of aspiration may be unreliable and insidious, because of the depressed cough reflex. Modified and traditional barium swallows should be performed following treatment to assess the safety of oral feeding and the structural integrity of the pharynx and esophagus. Patients with severe dysphagia may benefit from rehabilitation. Tube feeding should be continued for those with aspiration.
