ReviewIdentifying patients at risk for, and treatment of major psychiatric complications of cancer.
A critically important aspect of supportive care in cancer is the prompt recognition and effective treatment of psychiatric complications. Psychiatric disorders such as depression, anxiety and delirium occur in a significant percentage of cancer patients, particularly as disease advances and as cancer treatments become more aggressive. This paper reviews factors that can be utilized to identify patients who are at increased risk for developing psychiatric complications, such as those with advanced disease, certain cancer treatments, uncontrolled physical symptoms, functional limitations, lack of social support, and past history of psychiatric disorder. Methods of diagnostic assessment and strategies for managing depression, anxiety, delirium and suicidal ideation are also reviewed.

ReviewTreatment of chemotherapy-induced emesis in the 1990s: impact of the 5-HT3 receptor antagonists.
Considerable progress has been made in the development of means to limit nausea and vomiting arising from cancer chemotherapy. A number of key conceptual advances in the last decade have been critically important. these include recognition of the value of combination antiemetic therapy, identification of important patient- and treatment-related factors predictive of emesis, and appreciation of the importance of serotonin (5-HT) in the pathophysiology of emesis and the value of selective antagonists of the type-3 serotonin receptor. Comparative trials of the 5-HT3 receptor antagonists and classic antiemetic agents have helped define optimal antiemetic approaches in a number of settings. ⋯ Results of trials comparing 5-HT3 antagonists are beginning to emerge. Available information suggests no clinically relevant differences in antiemetic efficacy between these agents. Many questions regarding the optimal use of the 5-HT3 antagonists and their integration into clinical practice remain unanswered and are the appropriate focus for additional study.

Review Comparative StudyOverview of current development in patient-controlled analgesia.
Over the past two decades, numerous trials have assessed the safety and efficacy of patient-controlled analgesia (PCA). Advantages over conventional parenteral narcotics reported from these trials include equivalent to superior pain relief, superior patient satisfaction, decreased sedation and anxiety, faster return to normal functional status, and reduction in nursing time and hospitalization. The majority of these trials have been conducted in the postoperative patient population. ⋯ A comparison of these types of PCA devices is described. The limitations of the literature involving PCA therapy in cancer patients make it difficult to identify optimal patient selection criteria, PCA administration schedules, drug selection and dosing, and optimal route of administration. The current status and pertinent issues related to these topics are addressed.

Comparative StudyOn the relationship between nausea and vomiting in patients undergoing chemotherapy. Italian Group for Antiemetic Research.
In comparative trials on antiemetic efficacy of different regimens, the positive correlation between the probabilities of vomiting and of nausea could hide some confounding effect. Our work seeks to detect such effects. The data from two large studies on prevention of cisplatin-induced emesis were re-analyzed using two multifactorial logistic models. ⋯ Instead, in the second study, the greater efficacy of Mtc/Dex/Dip in preventing both nausea and vomiting was confirmed. The results indicate that, when a correlation between two responses is detected, multifactorial analyses should be performed to identify the possible presence of some confounding effect. The proof that the presence/absence of vomiting is a confounding factor for the relationship between the different efficacy of the two antiemetic regimens for complete protection from nausea, highlighting the same efficacy of the two therapies in preventing nausea, supports the hypothesis of the existence of two kinds of nausea, one independent of vomiting, the other concomitant with it.
