Portenoy, R.K., Thomas, J., Moehl Boatwright, M.L., Tran, D., Galasso, F.L., Stambler, N., . . . Israel, R.J. (2008). Subcutaneous methylnaltrexone for the treatment of opioid-induced constipation in patients with advanced illness: A double-blind, randomized, parallel group, dose-ranging study. Journal of Pain and Symptom Management, 35, 458-468.
To assess the efficacy and safety of subcutaneous methylnaltrexone in patients with advanced illness and opioid-induced constipation (OIC), and to clarify whether a dose-response relationship could be identified.
Methylnaltrexone was administered in doses of 1 mg, 5 mg, or 12.5 mg subcutaneously; patients were randomized to those dose groups in a ratio of 1:1:1. After 22 patients, the dose range was extended to 20 mg; patients were randomized in a ratio of 1:1:3 to 1-mg, 12.5-mg, or 20-mg dose groups. Patients received study medication if they had no bowel movement for at least two days and had a score of 3 or higher on a 5-point scale assessing constipation-related distress. Patients receiving laxatives had to be on a stable regimen for at least four days and remain on regimen during the study.
During the first week of the study, subcutaneous injections were administered on days 1, 3, and 5. Following the first week of double-blind study, patients received the option for open-label study for a maximum of three weeks. The initial dose was 5 mg subcutaneously as often as every other day. The maximum dose was 15 mg in the first 22 patients and 20 mg for the remaining 11 patients. Dose could be increased or decreased by the investigator.
Multi-center
This randomized controlled, parallel-group, repeated-dose, dose-ranging trial included a double-blind phase for one week followed by an open-labeled phase for a maximum of three weeks.
Twenty-two patients completed the blinded phase, and 14 completed the open-label phase.
In the blinded phase, laxation occurred within four hours on day 1 for 1 of 10 patients (10%) in the 1-mg dose group, 3 of 7 patients (43%) in the 5-mg dose group, 6 of 10 patients (60%) in the 12.5-mg dose group, and 2 of 6 patients (33%) in the 20-mg dose group. On day 2, for all dose groups higher than 1 mg, 11 of 23 patients (48%) responded (p = 0.05). There was no dose-response relationship across the three highest doses compared to the 1-mg dose.
The median time to laxation was higher than 48 hours for the 1-mg dose group and 1.72, 0.48, and 6.75 hours in the 5-, 12.5-, and 20-mg dose groups, respectively. The median time to laxation was 1.26 hours for all patients dosed 5 mg or higher, and was statistically significant compared to the 1-mg group (p < 0.0003). The 1-mg dose group required laxative rescue approximately twice as often as other groups. There was no trend in worsening pain control over time.
In the open-label phase, the response rate was from 49% to 64% for patients in dose groups from 5 mg to 12.5 mg. Secondary outcomes were not evaluated because of the small sample size.
Methylnaltrexone doses of 5 mg or higher in patients with advanced illness relieved OIC without decreased analgesia or withdrawal symptoms.

Nabiximols for opioid-treated cancer patients with poorly-controlled chronic pain: A randomized, placebo-controlled, graded-dose trial. The Journal of Pain: Official Journal of the American Pain Society, 13(5), 438–449.
To obtain information about the dose response for analgesia and safety in a population with medical illness and pain that is inadequately controlled by an opioid
Patients were randomly assigned to different-dose groupings of nabiximol or placebo delivered as an oral spray. Study design included a 5- to 14–day baseline period, five weeks of treatment titration, and a poststudy follow-up after two weeks. Patients received a daily call, from a voice recording system, that asked them to grade average pain. Patients continued the use of scheduled opioids and usual analgesics for the treatment of breakthrough pain. Patients who received at least one dose of the study drug were included in intent-to-treat analysis.
Randomized placebo-controlled, graded-dose trial
Nabiximols can be beneficial in the treatment of the refractory pain of patients with cancer. This study represents a start in regard to discovering the optimum dose effect and safety of nabiximols. In this study, low to medium doses were associated with the greatest effect.
This study affects nursing by providing a potential treatment option for patients with opioid-refractory pain. Nurses should be able to recognize opioid-refractory patients. Nurses should be educated regarding this novel cannabinoid treatment, its administration, and its side effects. Nurses should be able to teach patients how to use nabiximols.
Poppelreuter, M., Weis, J., & Bartsch, H.H. (2009). Effects of specific neuropyschological training programs for breast cancer patients after adjuvant chemotherapy. Journal of Psychosocial Oncology, 27(2), 274–296.
The study was conducted to evaluate the need of patients with breast cancer for neuropsychological rehabilitation after adjuvant chemotherapy. It also sought to determine the effectiveness of differentiated training programs after completion of treatment.
Participants were randomly assigned to one of two intervention groups. Control participants were selected from the “time-out” phase of the study when no training was being offered.
Both intervention groups took part in four one-hour training sessions per week during their inpatient stay. Participants were randomized to one of the following outpatient interventions.
Measures were completed upon admission to the rehabilitation unit (T1), at the end of in-patient rehabilitation (T2), and six months later on an outpatient basis (T3).
The study took place at the Tumor Biology Center Rehabilitation Unit in Freiburg, Germany.
The study utilized a randomized, controlled trial.
No intervention effects were noted in this study. Significant improvement was noted in 11 of 16 neuropsychiatric parameters for all three groups between T1 and T2. Forty participants (44.4%) maintained at least one cognitive deficit at five months; 19 (21.1%) maintained two or more deficits at T3.
Both intervention groups received similar amounts of training sessions. Eighty-four participants (87.5%) had at least one impaired neuropsychological parameter and 54 (56.2%) had two or more at baseline.
No significant differences in cognitive ability between treatment groups were reported.

Impact of hematopoietic growth factors on blood transfusion needs, incidence of neutropenia, and overall survival among elderly advanced ovarian cancer patients treated with chemotherapy. International Journal of Gynecological Cancer, 26, 95–103.
To determine the effectives of an erythropoietin-stimulating agent (ESA) and granulocyte–colony-stimulating factor (G-CSF) in reducing blood transfusion needs and neutropenia incidence in community-dwelling older adults with ovarian cancer
Woman aged older than 65 years diagnosed with stage III–IV epithelial ovarian cancer (from January 2000–December 2009) were identified as having received chemotherapy by procedure codes in Medicare within nine months of diagnosis. Cox models were used for analysis and included time-dependent covariates. ESAs and G-CSFs were identified by Healthcare Common Procedure Coding System codes for epoetin-alfa/darbepoetin-alfa and filgrastim/pegfilgrastim. Blood transfusion need was measured from the time of diagnosis to first Medicare claim indicating the receipt of blood transfusion. Neutropenia incidence was measured from the time of the first chemotherapy administration to the first claim of neutropenia. Patients who did not receive a blood transfusion or did not develop neutropenia were censored at the date of death or last date in Medicare claims (i.e., December 31, 2010), whichever occurred first. Overall survival was measured from the time of first chemotherapy administration until death or the end of the follow-up period (December 31, 2011). Patients not experiencing the event (death) by this date were censored.
Retrospective cohort study using SEER Medicare linked database
ESAa were effective in reducing blood transfusion need. G-CSFs were effective in lowering neutropenia incidence and were associated with improved survival in older adults with ovarian cancer. The interaction between ESA time and CSF time was significant (p = 0.0001).
The findings demonstrated that using epoetin-alfa or darbepoetin-alfa effectively lowers the blood transfusion needs by 48%–78% in patients receiving chemotherapy, which is comparable to prior randomized trials of patients with gynecologic and ovarian cancer. The use of a G-CSF was associated with a longer survival compared to those who received at least three doses of a G-CSF. The findings showed that patients who received fewer than three prophylactic G-CSF administrations did not experience better outcomes.
This was a good study; however, it had a very focused patient population and may not be reproducible in the younger population. In addition, no information was provided regarding adverse events related to the use of ESAs or G-CSFs. Prior studies have shown a possible higher risk for mortality with the use of ESAs and G-CSFs. It is important to continue to look at established guidelines (Oncology Nursing Society, American Society for Clinical Oncology, National Comprehensive Cancer Network, Food and Drug Administration) for the use of ESAs and G-CSFs in the cancer population.

To assess effectiveness of calendula for prevention of acute radiation-induced dermatitis of grade 2 or higher during radiation therapy compared with trolamine
Patients were randomly allocated to application of trolamine or calendula on irradiated fields after each session. Patients started topical application of ointment at onset of radiation therapy, twice a day or more, depending on occurrence of dermatitis and pain, until completion. Patients were instructed not to use the agent two hours or less before an irradiation session or before treatment evaluation. No other prophylactic creams, lotions, or gels were allowed. Physicians were free to treat established dermatitis grade 2 or higher or allergy as considered appropriate. Clinicians were blinded to the treatment used
The study took place at Centre Leon Berard in Lyon, France.
The study used a randomized, blinded controlled trial design.
The occurrence of acute dermatitis of grade 2 or higher was significantly lower (41% versus 63%; p < .001) with use of calendula versus trolamine. Benefits were most marked at sites at risk of maceration (submammary fold, armpit, and tangential area) and sites with thin skin. Patients receiving calendula had less frequent interruption of radiation therapy. Mean length of treatment interruption was 10 days (range 2–22 days). Fifteen treatment interruptions were observed in trolamine group, 12 due to skin toxicity. No allergic reactions were observed in the calendula group, whereas four patients in the trolamine group developed allergic-type reactions of pruritus and urticaria. Patients receiving calendula had significantly reduced radiation-induced pain. Mean maximal pain evaluated in calendula group was 1.54 and 2.10 in the trolamine group (p = 0.03). Self-assessed satisfaction was greater with calendula. Prevention of erythema was 69% in the calendula arm versus 39% in the trolamine arm. Prevention of pain was 65% with calendula versus 46% with trolamine. Calendula was considered more difficult to apply as noted by 30% of the calendula group versus 5% of trolamine group. The risk of skin toxicity of grade 2 or higher was significantly increased for women whose body mass index was 25 or higher (p < 0.001), who had received chemotherapy before radiation therapy after a lumpectomy (p = 0.01), and who were using trolamine (p < 0.001).
Calendula was shown to be effective in reducing skin toxicity of radiation compared to trolamine.
Because of differences in texture, color, and smell, it was not possible to perform a double-blind randomized study.

Pollak, J.S., Burdge, C.M., Rosenblatt, M., Houston, J.P., Hwu, W.J., & Murren, J. (2001). Treatment of malignant pleural effusions with tunneled long-term drainage catheters. Journal of Vascular and Interventional Radiology: JVIR, 12(2), 201-208.
The objective of the study was to assess the effectiveness of tunneled pleural catheters in the treatment of malignant pleural effusions.
Initial enrollment of the first one-third of patients (n = 9) involved 2:1 randomization to the newly available and not U.S. Food and Drug Administration (FDA)-licensed PleurX® catheter or chest tube-administered chemical pleurodesis with doxycycline. The remaining 19 patients after October 1997 all were treated with the PleurX® catheter.
The study had a prospective convenience sample, with randomization of the initial one-third of patients. The study for the remaining two-thirds of the patients had a nonrandomized prospective design.
This small, single-site, prospective study of the effectiveness of tunneled pleural catheters showed effective pleural drainage, spontaneous pleurodesis equivalent to chest catheter pleurodesis, reduced days of hospitalization (as the procedure can be safely performed outpatient), reduced distressing symptoms, and rare complications.
Its use in patients with refractory effusions could be advantageous, as it represents patients who have received other therapies prior to catheter insertion. The average life expectancy of patients with malignant pleural effusions is only 6–12 months, with as many as half of patients dying within 30 days. Patients with malignant pleural effusions represent a group who experience significant symptoms that affect quality of life. Interventions that are low-intensity, can be performed quickly and with limited recovery time, and can be managed in the ambulatory or home setting are optimal. Nurses can act as advocates for innovative management of malignant pleural effusions that enhance patient independence. Nurses are key patient and family educators who provide guidance, support, and hands-on instruction in management of tunneled pleural catheters. Their follow-up with patients and caregivers assist in the detection of complications, as well as evaluation of efficacy. Follow-up nursing assessment for symptom relief and spontaneous pleurodesis or the need for additional interventions may be especially important for these patients receiving end-of-life care with limited contact with physicians.

The purpose of the study was to measure the efficacy of black cohosh (one capsule, Cimicifuga racemosa 20 mg twice daily) for the treatment of hot flashes in women with and without a history of breast cancer.
Participants received four weeks of therapy with black cohosh or an identical appearing placebo. The black cohosh or placebo was given as one tablet twice per day. After completing the first four weeks, participants were crossed over to the alternative treatment arm.
This was a double-blind, randomized, cross-over clinical trial with two four-week periods.
Participants completed a prospective, daily hot flash diary during the baseline week and then during the two four-week crossover treatment periods. Hot flash scores were measured by assigning points to each hot flash based on severity (1 for mild to 4 for very severe) and then adding the points for a given time period.
The primary end point was the average intrapatient hot flash score (which is a construct of average daily hot flash severity and frequency) difference between the baseline week and the last study week of the first treatment period. Hot flash activity was analyzed in a number of ways. The difference between treatment week 4 (study week 5) and baseline hot flash score (study week 1) was compared between placebo and black cohosh arms by standard two-sided Wilcoxon procedures. Confidence intervals were constructed for median reductions in hot flash frequency and score. Patients receiving black cohosh reported a mean decrease in hot flash score of 20% (comparing the fourth treatment week to the baseline week) compared with a 27% decrease for patients on placebo (p = .53). Mean hot flash frequency was reduced 17% on black cohosh and 26% on placebo (p = .36). Patient treatment preferences were measured after completion of both treatment periods. Thirty-four percent of patients preferred the black cohosh treatment, 38% preferred the placebo, and 28% did not prefer either treatment. Toxicity was minimal across both groups.
This trial failed to provide any evidence that black cohosh reduced hot flashes more than the placebo.
Limitations of the study included using a subset of participants did not have a diagnosis of breast cancer but met the eligibility criteria of a perceived increased risk of breast cancer, or did not want to take estrogen because of the increased risk of breast cancer. The numbers of participants with and without a breast cancer diagnosis were not specified.

PHASE OF CARE: Late effects and survivorship
One botanical intervention, alpha benzopyrones, had benefits that were balanced with harms, but the effectiveness of all other botanical interventions was not established. At this time, botanical supplements cannot be recommended as part of a therapeutic protocol to manage lymphedema in patients with cancer.
At this time, there is limited high-quality evidence investigating the potential use of botanicals in the treatment of cancer-related lymphedema. The number of studies using botanical interventions is small, and most possess significant design flaws. This review did not clearly state the inclusion and exclusion criteria used to select literature, and patient demographics were not described.
At this time, botanical supplements should not be considered as part of routine care in the treatment of cancer-related lymphedema. Nurses must be knowledgeable about the various botanical supplements patients may be using, and they must always assess patients for the use of any botanical supplements. Nurses should council patients who are taking or who ask about botanical supplements on the current state of the research.
