Background: Earlier studies have shown that up to 43% of patients with incurable cancer are treated with palliative chemotherapy in the last month of their lives. Although pretreatment blood tests are acceptable, the patient's general condition may not permit further palliative chemotherapy treatment (PCT). Presently, there is no patient self-assessment tool available to monitor performance status during PCT.

Objectives: To describe the development process of the Performance Status in Palliative Chemotherapy (PSPC) questionnaire, and the testing of its psychometric properties.

Methods: The questionnaire was developed by the authors based on the Eastern Cooperative Oncology Group Performance Status Rating (ECOG PSR) scale as well as their clinical experience with PCT. Adult patients who were diagnosed with epithelial cancers (n = 118) were enrolled to test the PSPC questionnaire for reliability, sensitivity for change, and validity.

Results: After stepwise modifications of the PSPC questionnaire, psychometric tests revealed acceptable values for reliability (via a test-retest method), sensitivity for change (via a comparison of patients with progressive disease over time), and validity (via a comparison of the PSPC vs the Edmonton Symptom Assessment System [ESAS]).

Limitations: At this stage of questionnaire development, we are unable to conclude whether the PSPC is superior to the conventional ECOG PSR in the evaluation of performance status and the prediction of chemotherapy response.

Conclusion: Psychometric tests suggest that the PSPC questionnaire may be a useful patient-completed tool in the late stages of cancer disease to routinely monitor performance status in palliative chemotherapy treatments so as to minimize the risk of inflicting more harm than good.

Patients with a life-limiting illness frequently experience pain and other symptoms. It is important to pay close attention when medication therapy is used to manage these symptoms. Occasionally, practitioners need to be creative in selecting, dosing, administering, and discontinuing medications at the end of life because of the patient's changing health care needs. This article offers practical end-of-life medication tips including, but not limited to, medication administration; guidance on how to increase and decrease doses; medication selection for difficult-to-treat patients; alternative dosage formulations; routes of medication administration; debridement medication regimens; and appropriate drug therapy selection.

Buprenorphine is an opioid that has a complex and unique pharmacology which provides some advantages over other potent mu agonists. We review 12 reasons for considering buprenorphine as a frontline analgesic for moderate to severe pain: (1) Buprenorphine is effective in cancer pain; (2) buprenorphine is effective in treating neuropathic pain; (3) buprenorphine treats a broader array of pain phenotypes than do certain potent mu agonists, is associated with less analgesic tolerance, and can be combined with other mu agonists; (4) buprenorphine produces less constipation than do certain other potent mu agonists, and does not adversely affect the sphincter of Oddi; (5) buprenorphine has a ceiling effect on respiratory depression but not analgesia; (6) buprenorphine causes less cognitive impairment than do certain other opioids; (7) buprenorphine is not immunosuppressive like morphine and fentanyl; (8) buprenorphine does not adversely affect the hypothalamic-pituitary-adrenal axis or cause hypogonadism; (9) buprenorphine does not significantly prolong the QTc interval, and is associated with less sudden death than is methadone; (10) buprenorphine is a safe and effective analgesic for the elderly; (11) buprenorphine is one of the safest opioids to use in patients in renal failure and those on dialysis; and (12) withdrawal symptoms are milder and drug dependence is less with buprenorphine. In light of evidence for efficacy, safety, versatility, and cost, buprenorphine should be considered as a first-line analgesic.

Background: Chronic lymphocytic leukemia (CLL) patients are at high risk for acute respiratory illness (ARI).

Objective: We evaluated the safety and efficacy of a proprietary extract of Panax quinquefolius, CVT-E002, in reducing ARI.

Methods: This was a double-blind, placebo-controlled, randomized trial of 293 subjects with early-stage, untreated CLL conducted January-March 2009.

Results: ARI was common, occurring on about 10% of days during the study period. There were no significant differences of the 2 a priori primary end points: ARI days (8.5 ± 17.2 for CVT-E002 vs 6.8 ± 13.3 for placebo) and severe ARI days (2.9 ± 9.5 for CVT-E002 vs 2.6 ± 9.8 for placebo). However, 51% of CVT-E002 vs 56% of placebo recipients experienced at least 1 ARI (difference, -5%; 95% confidence interval [CI], -16% to 7%); more intense ARI occurred in 32% of CVT-E002 vs 39% of placebo recipients (difference, -7%; 95% CI, -18% to 4%), and symptom-specific evaluation showed reduced moderate to severe sore throat (P = .004) and a lower rate of grade ≥3 toxicities (P = .02) in CVT-E002 recipients. Greater seroconversion (4-fold increases in antibody titer) vs 9 common viral pathogens was documented in CVT-E002 recipients (16% vs 7%, P = .04).

Limitations: Serologic evaluation of antibody titers was not tied to a specific illness, but covered the entire study period.

Conclusion: CVT-E002 was well tolerated. It did not reduce the number of ARI days or antibiotic use; however, there was a trend toward reduced rates of moderate to severe ARI and significantly less sore throat, suggesting that the increased rate of seroconversion most likely reflects CVT-E002-enhanced antibody responses.

The admission of cancer patients into intensive care units (ICUs) is on the rise. These patients are at high risk for physical and psychosocial suffering. Patients and their families often face difficult end-of-life decisions that highlight the importance of effective and empathetic communication. Palliative care teams are uniquely equipped to help care for cancer patients who are admitted to ICUs. When utilized in the ICU, palliative care has the potential to improve a patient's symptoms, enhance the communication between care teams and families, and improve family-centered decision making. Within the context of this article, we will discuss how palliative care can be integrated into the care of ICU patients and how to enhance family-centered communication; we will also highlight the care of ICU patients at the end of life.

In 2009, the American College of Sports Medicine convened an expert roundtable to issue guidelines on exercise for cancer survivors. This multidisciplinary group evaluated the strength of the evidence for the safety and benefits of exercise as a therapeutic intervention for survivors. The panel concluded that exercise is safe and offers myriad benefits for survivors including improvements in physical function, strength, fatigue, quality of life, and possibly recurrence and survival. Recommendations for situations in which deviations from the US Physical Activity Guidelines for Americans are appropriate were provided. Here, we outline a process for implementing the guidelines in clinical practice and provide recommendations for how the oncology care provider can interface with the exercise and physical therapy community.

Background: eHealth resources for people facing health crises must balance the expert knowledge and perspective of developers and clinicians against the very different needs and perspectives of prospective users. This formative study explores the information and support needs of posttreatment prostate cancer patients and their partners as a way to improve an existing eHealth information and support system called CHESS (Comprehensive Health Enhancement Support System).

Methods: Focus groups with patient survivors and their partners were used to identify information gaps and information-seeking milestones.

Results: Both patients and partners expressed a need for assistance in decision making, connecting with experienced patients, and making sexual adjustments. Female partners of patients are more active in searching for cancer information. All partners have information and support needs distinct from those of the patient.

Conclusions: Findings were used to develop a series of interactive tools and navigational features for the CHESS prostate cancer computer-mediated system.

Background: Improved survivorship has led to increased recognition of the need to manage the side effects of cancer and its treatment. Exercise and psychological interventions benefit survivors; however, it is unknown if additional benefits can be gained by combining these two modalities.

Objective: Our purpose was to examine the feasibility of delivering an exercise and counseling intervention to 43 breast cancer survivors, to determine if counseling can add value to an exercise intervention for improving quality of life (QOL) in terms of physical and psychological function.

Methods: We compared exercise only (Ex), counseling only (C), exercise and counseling (ExC), and usual care (UsC) over an 8 week intervention.

Results: In all, 93% of participants completed the interventions, with no adverse effects documented. There were significant improvements in VO(2)max as well as upper body and lower body strength in the ExC and Ex groups compared to the C and UsC groups (P < .05). Significant improvements on the Beck Depression Inventory were observed in the ExC and Ex groups, compared with UsC (P < .04), with significant reduction in fatigue for the ExC group, compared with UsC, and no significant differences in QOL change between groups, although the ExC group had significant clinical improvement.

Limitations: Limitations included small subject number and study of only breast cancer survivors.

Conclusions: These preliminary results suggest that a combined exercise and psychological counseling program is both feasible and acceptable for breast cancer survivors and may improve QOL more than would a single-entity intervention.
