Background: The role of radiotherapy in palliation is well recognized. Analyzing referrals from an inpatient palliative care unit (PCU) to the radiation oncology (RO) service may help in planning palliative care (PC) services and educational programs.

Objective: To determine the pattern and rate of referrals from a PCU to the RO service at a tertiary oncology facility in Saudi Arabia.

Methods: Referrals from the PCU to the RO service were prospectively identified over the period beginning November 27, 2007 and ending March 9, 2011. The appropriateness of referrals was determined by 2 radiation oncologists.

Results: Of the 635 cancer admissions to the PCU, 25 (3.9%) referrals to RO were made, and 32 sites were irradiated. All patients had a poor performance status (ECOG > or = 3). The most common areas irradiated were vertebrae (40.6%), pelvis (18.7%) and other bony structures (28.1%). Pain control was the most frequent reason for referral (87.5%). Only one referral was regarded by the RO service as inappropriate, indicating that 96% of the referrals were appropriate. The mean time lapse between referral and starting radiation was 4 +/- 3.6 days. A total of 75% of the patients died in the PCU within a median of 30 days post radiotherapy.

Conclusion: The small minority of patients in the PCU referred for radiotherapy were deemed appropriate referrals by the radiation oncologists despite their poor performance status and limited time remaining. When planning a PCU with similar admission criteria, the availability of a radiotherapy facility in close proximity may not be a priority.

Background: Burnout among physicians can lead to decreased career satisfaction, physical and emotional exhaustion, and increased medical errors. In oncologists, high exposure to fatal illness is associated with burnout.

Methods: The Maslach Burnout Inventory, measuring Emotional Exhaustion (EE), Depersonalization (DP), and Personal Accomplishment (PA), was administered to second-year US oncology fellows. Bivariate and multivariate analyses explored associations between burnout and fellow demographics, attitudes, and educational experiences.

Results: A total of 254 fellows out of 402 eligible US fellows responded (63.2%) and 24.2% reported high EE, 30.0% reported high DP, and 26.8% reported low PA. Over half of the fellows reported burnout in at least one domain. Lower EE scores were associated with the fellows' perceptions of having received better teaching, explicit teaching about certain end-of-life topics, and receipt of direct observation of goals-of-care discussions. Fellows who reported better overall teaching quality and more frequent observation of their skills had less depersonalization. Fellows who felt a responsibility to help patients at the end of life to prepare for death had higher PA.

Limitations: This survey relies on the fellows' self-reported perceptions without an objective measure for validation. Factors associated with burnout may not be causal. The number of analyses performed raises the concern for Type I errors; therefore, a stringent P value (0.01) was used.

Conclusions: Burnout is prevalent during oncology training. Higher-quality teaching is associated with less burnout among fellows. Fellowship programs should recognize the prevalence of burnout among oncology fellows as well as components of training that may protect against burnout.

Background: The impact of arm morbidity following breast cancer surgery on patient-observed changes in daily functioning and health-related quality of life (HRQoL) has not been well-studied.

Objective: To examine the association of objective measures such as range of motion (ROM) and lymphedema, with patient-reported outcomes (PROs) in the arm and breast, upper extremity function, activities, and HRQoL.

Methods: The National Surgical Adjuvant Breast and Bowel Project Protocol B-32 was a randomized trial comparing sentinel node resection (SNR) with axillary dissection (AD) in women with node-negative breast cancer. ROM and arm volume were measured objectively. PROs included symptoms; arm function; limitations in social, recreational, occupational, and other regular activities; and a global index of HRQoL. Statistical methods included cross-tabulations and multivariable linear regression models.

Results: In all, 744 women provided at least 1 postsurgery assessment. About one-third of the patients experienced arm mobility restrictions. A similar number of patients avoided the use of the arm 6 months after surgery. Limitations in work and other regular activities were reported by about a quarter of the patients. In this multivariable analysis, arm mobility and sensory neuropathy were predictors of patient-reported arm function and overall HRQoL. Predictors for activity limitations also included side of surgery (dominant vs nondominant). Edema was not significant after adjustment for sensory neuropathy and ROM.

Limitations: Arm mobility and edema were measured simultaneously only once during the follow-up (6 months).

Conclusion: Clinical measures of sensory neuropathy and restrictions in arm mobility following breast cancer surgery are associated with self-reported limitations in activity and reductions in overall HRQoL.

Nausea and vomiting are common and distressing symptoms in advanced cancer. Both are multifactorial and cause significant morbidity, nutritional failure, and reduced quality of life. Assessment includes a detailed history, physical examination and investigations for reversible causes. Assessment and management will be influenced by performance status, prognosis, and goals of care. Several drug classes are effective with some having the added benefit of multiple routes of administration. It is our institution's practice to recommend metoclopramide as the first drug with haloperidol as an alternative antiemetic. Dexamethasone should be used for patients with central nervous system metastases or bowel obstruction. If your patient is near death, empiric metoclopramide, haloperidol or chlorpromazine is used without further investigation. For patients with a better prognosis, we exclude reversible causes and use the same first-line antiemetics, metoclopramide and haloperidol. For those who do not respond to first-line single antiemetics, olanzapine is second line and ondansetron is third. Rarely do we use combination therapy or cannabinoids. Olanzapine as a single agent has a distinct advantage over antiemetic combinations. It improves compliance, reduces drug interactions and has several routes of administration. Antiemetics, anticholinergics, octreotide and dexamethasone are used in combination to treat bowel obstruction. In opiod-na'ive patients, we prefer haloperidol, glycopyrrolate and an opioid as the first-line treatment and add or substitute octreotide and dexamethasone in those who do not respond. Non-pharmacologic interventions (mechanical stents and percutaneous endoscopic gastrostomy tubes) are used when nausea is refractory to medical management or for home-going management to relieve symptoms, reduce drug costs and rehospitalization.

Background: Coenzyme Q10 (CoQ10) is a common antioxidant supplement with known cardioprotective effects and potential anticancer benefits.

Objectives: We performed a randomized, double-blind, placebo-controlled study of oral CoQ10 in female breast cancer patients with the primary objective of determining CoQ10's effects on self-reported fatigue, depression, and quality of life (QOL). Methods Eligible women with newly diagnosed breast cancer and planned adjuvant chemotherapy were randomized to oral supplements of 300 mg CoQ10 or placebo, each combined with 300 IU vitamin E, divided into 3 daily doses. Treatment was continued for 24 weeks. Blood tests, QOL measures, and levels of plasma CoQ10 and vitamin E were obtained at baseline and at 8, 16, and 24 weeks. Mixed-effects models were used to assess treatment differences in outcomes over time.

Results: Between September 2004 and March 2009, 236 women were enrolled. Treatment arms were well balanced with respect to age (range, 28-85 years), pathologic stage (stage 0, 91%; stage 1, 8%; stage II, 1%), ethnicity (white, 87%; black, 11%; Hispanic, 2%), and planned therapy. Baseline CoQ10 levels in the CoQ10 and placebo arms were 0.70 and 0.73 microg/mL, respectively; the 24-week CoQ10 levels were 1.83 and 0.79 microg/mL, respectively. There were no significant differences between the CoQ10 and placebo arms at 24 weeks for scores on the Profile of Mood States-Fatigue questionnaire (least squares means, 7.08 vs 8.24, P = .257), the Functional Assessment of Chronic Illness Therapy-Fatigue tool (37.6 vs 37.6, P = .965), the Functional Assessment of Cancer Therapy-Breast Cancer instrument (111.9 vs 110.4, P = .577), or the Center for Epidemiologic Studies-Depression scale (11.6 vs 12.3, P = .632).

Conclusions: Supplementation with conventional doses of CoQ10 led to sustained increases in plasma CoQ10 levels but did not result in improved self-reported fatigue or QOL after 24 weeks of treatment.

Background: Even with modern antiemetic regimens, up to 20% of cancer patients suffer from moderate to severe chemotherapy-induced nausea and vomiting (CINV) (> or = grade 2). We previously developed chemotherapy cycle-based risk predictive models for > or = grade 2 acute and delayed CINV. In this study, the prospective validation of the prediction models and associated scoring systems is described.

Objective: Our objective was to prospectively validate prediction models designed to identify patients at high risk for moderate to severe CINV.

Methods: Patients receiving chemotherapy were provided with CINV symptom diaries. Prior to each cycle of chemotherapy, the acute and delayed CINV scoring systems were used to stratify patients into low- and high-risk groups. Logistic regression was used to compare the occurrence of > or = grade 2 CINV between patients considered by the model to be at high vs low risk. The external validity of each system was assessed via an area under the receiver operating characteristic (AUROC) curve analysis.

Results: Outcome data were collected from 97 patients following 401 cycles of chemotherapy. The incidence of > or =grade 2 acute and delayed CINV was 13.5% and 21.4%, respectively. There was a significant correlation between the risk score and the probability of developing acute and delayed CINV following chemotherapy. Both the acute and delayed scoring systems had good predictive accuracy when applied to the validation sample (acute, AUROC = 0.70, 95% CI, 0.62-0.77; delayed, AUROC = 0.75, 95% CI, 0.69-0.80). Patients who were identified as high risk were 3.1 (P = .006) and 4.2 (P< .001) times more likely to develop - grade 2 acute and delayed CINV than were those identified as low risk.

Conclusion: This study demonstrates that the scoring systems are able to accurately identify patients at high risk for acute and delayed CINV.

What are the ethical responsibilities of the medical staff (doctors, nurses, social workers, and chaplains) regarding the preservation of meaningful life for their patients who are approaching the end of life (EOL)? In particular, what is the staff's ethical responsibility to initiate a conversation with their patient regarding palliative care? By subjecting traditional Jewish teachings to an ethical analysis and then exploring the underlying universal principles, we will suggest a general ethical duty to inform patients of the different care options, especially in a manner that preserves hope. The principle that we can derive from Jewish bioethics teaches that the medical staff has a responsibility to help our patients live in a way that is consistent with how they understand their task or responsibility in life. For some patients, the best way to preserve a meaningful life in which they can fulfill their sense of purpose in the time that remains is to focus on palliation. For this reason, although palliative and supportive care are provided from the time of diagnosis, it is critical we make sure our patients realize that they have the opportunity to make a decision between either pursuing additional active treatments or choosing to focus primarily on palliative therapies to maximize quality of life. The Jewish tradition and our experience in spiritual care suggest the importance of helping patients preserve hope while, simultaneously, honestly acknowledging their situation. Staff members can play a vital role in helping patients make the most of this new period of their lives.
