To determine the effect of oral proteolytic enzymes for prevention of acute side effects in patients with head and neck cancer.
Patients were randomly assigned to the control or experimental group.
The enzymes taken were a combination of papain 100 mg, trypsin 40 mg, and chymotrypsin 40 mg (MUCOS Pharma). Patients took three tablets, three times per day, three days prior to start of radiation therapy (RT), and up to five days after completion.
Mucositis, skin reaction, and dysphagia were graded at each visit during and after RT. Scoring was done at baseline, weekly, and five to six months following treatment.
The study was a prospective, randomized, open-label trial.
Oral proteolytic enzymes may be helpful in reducing the severity of radiodermatitis.

To determine the effectiveness of an assistive mobile flexion bar during exercise to reduce arm volume in patients diagnosed with lymphedema related to breast cancer treatment
Participants were randomly selected, and all participants received the intervention. Participants received a single one hour of active exercising split into 12-minute sections with 3 minutes of flexion bar use between each section. The flexion bar is a T-shaped apparatus, the vertical bar remains fixed (10 cm away from the patient on a tabletop), and the horizontal bar rotates (30 cm above the tabletop) to allow extension and flexion of arm muscles. All of the participants wore a compression sleeve on the affected limb. The participants independently performed the exercise routine, and the sole purpose of the interventionist was to control the time of exercise intervals and to help participants maintain proper posture and spinal alignment.
The study took place at a rehabilitation facility in Brazil.
Patients were undergoing active lymphedema treatment.
The study used a prospective trial design.
The participants initial mean volume was 2,089.9 ml. After the exercise session, the mean final volume decreased to 2,023.0 ml. The study used a paired t-test with an alpha error of 5% as acceptable. The results concluded in a mean loss of 66.9 ml (p < 0.001). There was a significant reduction in limb volume, using active exercises with a facilitating device (mobile flexion bar).
The trial suggests that the use of an apparatus mobile flexion bar may improve the efficacy of lymphedema reduction by myolymphokinetic exercises. Active exercises are beneficial to patients with lymphedema because it promotes muscle contraction and lymphatic drainage. The study has its risks for bias based on the small sample size and the lack of a control group.
Because of the statistical significance of the findings of the study, it is important for nurse researchers to repeat the study using a more rigorous study design. If the experiment were repeated as a randomized controlled trial with a larger sample size, the results would be more generalizable. It would also be interesting to compare the use of a mobile flexion bar to active exercise without the use of a facilitating device to determine the necessity.

STUDY PURPOSE: To investigate the efficacy of antidepressants and anticonvulsants in combination therapy for neuropathic pain in patients with cancer
TYPE OF STUDY: Meta-analysis and systematic review
PHASE OF CARE: Multiple phases of care
APPLICATIONS: Palliative care
When both types of interventions were considered, use of these adjuvant medications in combination pharmacotherapy was superior to control regimens (p < 0.010, MD = -0.41). However, in subgroup analysis, anticonvulsants (MD = -0.12, 95% CI [-0.64, 0.39]) did not show a significant effect. Antidepressants showed some efficacy (MD = -0.54, 95% CI [-0.94, -0.12]) based on only two studies. Anticonvulsants showed better efficacy among studies including only chemotherapy-induced neuropathic pain. Withdrawals in experimental groups was two times higher than in control groups. Study duration ranged from 10 days to 6 weeks.
Use of adjuvant antidepressants and anticonvulsants had a significant but small effect on neuropathic pain, and anticonvulsants considered alone showed no overall significant effectiveness. Evidence was too limited to formulate a recommendation for use.
There is limited evidence to demonstrate effectiveness of anticonvulsants or antidepressants as adjuvant medications for neuropathic pain management, and high withdrawal rates in studies within groups receiving these drugs may point to their potential side effects. Nurses need to be aware of and monitor the adverse side effects of these medications.

Comparative effectiveness of white blood cell growth factors on neutropenia, infection, and survival in older people with non-Hodgkin's lymphoma treated with chemotherapy. Journal of the American Geriatrics Society, 58, 1885–1895.
To examine the effect of colony-stimulating factors (CSFs) used as primary and secondary prophylaxis on incidence of febrile neutropenia, infection, and survival in older adults.
The study used data from the Surveillance, Epidemiology, and End Results (SEER) Medicare database. ICD-9 codes were used to define inclusion diagnoses and definition of febrile neutropenia.
Use of CSF, the type of chemotherapy administered, and the use of antibiotics were defined in terms of CPT codes. Regression analysis was used to analyze effects of primary and secondary CSF prophylaxis on outcomes of interest. Primary prophylaxis was defined as CSF during chemotherapy before occurrence of fever, infection, or neutropenia. Secondary prophylaxis was CSF administration that occurred after these events. Study used data from 1992–2002.
Multi-site (SEER data)
There were mutliple phases of care
Application is for elder care
Retrospective cohort study
Sixty percent of cases did not receive any CSF. Those who had 5–9 CSF administrations for primary prophylaxis has a 42% lower risk of febrile neutropenia (OR = 0.58, 95% confidence interval [CI] [0.41, 0.83]) and those with 10 or more administrations had a 48% lower risk after data were adjusted for age, marital status, stage, and other characteristics. Those with 5–9 administrations had a 27% lower incidence of infection, and those with 10 or more administrations had a 52% lower risk (OR = 0.48, 95% CI [0.35, 0.66]). Primary prophylactic CSF was not associated with longer overall survival. Secondary prophylaxis was associated with improved overall survival, with a strong dose-response effect. A range of 11–23 administrations was associated with a 23% lower risk of mortality (HR = 0.77, 95% CI [0.71, 0.84]), and those with more than 23 administrations had a 13% lower risk of mortality than others. Protective effects of primary prophylaxis was highest in those receiving the largest number of chemotherapy administrations and in those with large B-cell lymphoma.
Primary prophylaxis with CSF in older adults is effective in preventing febrile neutropenia and infection, but was not associated with improved survival. Secondary prophylaxis was associated with longer overall survival.
Findings support the use of primary prophylactic CSF for prevention of infection and febrile neutropenia, and secondary prophylaxis in improving survival in this group of patients. Limitation of retrospective statistical analysis using medical records code data only need to be considered in interpretation and application of these results.

Journal of Clinical Oncology, 29, 1495–1501.
To evaluate the effectiveness of a single dose of fosaprepitant in combination with dexamethasone and 5-HT3 for chemotherapy-induced nausea and vomiting (CINV)
The study was conducted at multiple outpatient settings in 27 different countries.
All patients were in active treatment.
The study was a double-blind, randomized-controlled, parallel group.
The following measurement tools were used.

Effectiveness of a single-day three-drug regimen of dexamethasone, palonosetron, and aprepitant for the prevention of acute and delayed nausea and vomiting caused by moderately emetogenic chemotherapy. Supportive Care in Cancer, 17, 589–594.
To evaluate the safety and efficacy of aprepitant, dexamethasone, and palonosetron as an antiemetic regimen for prevention of acute and delayed nausea and vomiting
Patients received one oral dose of 285 mg aprepitant and 20 mg dexamethasone one hour prior to cyclophosphamide and/or doxorubicin chemotherapy and 25 mg IV palonosetron 30 minutes prior to chemotherapy. Patients completed study diaries prior to the start of the single-day chemotherapy and then daily for five days.
The study was conducted at multiple outpatient settings in Vermont and Maine.
All patients were in active treatment.
The study was a prospective trial.
The single-day, three-drug (aprepitant, dexamethasone, palonosetron) antiemetic regimen is a safe and effective antiemetic regimen for patients receiving mildly or minimally emetogenic chemotherapy.
Identifying effective single-day antiemetic regimens may improve adherence to supportive care guidelines and reduce nausea and vomiting symptoms in patients receiving chemotherapy.

A single dose of preoperative gabapentin for pain reduction and requirement of morphine after total mastectomy and axillary dissection: Randomized placebo-controlled double-blind trial. Journal of Postgraduate Medicine, 55(4), 257–260.
To investigate the effect of a single low dose (600 mg) of preoperative oral gabapentin on morphine consumption after total mastectomy and axillary dissection; to determine if the specified administration of gabapentin is safe
Before total mastectomy and axillary dissection, patients received 600 mg gabapentin or placebo. Pain, sedation, nausea, vomiting, and side effects were monitored every 30 minutes for 2 hours and then every 2 hours until 12 hours after surgery.
Randomized double-blind placebo-controlled trial
Pre-emptive administration of a single oral dose of gabapentin, 600 mg, led to a decrease in the use of postoperative analgesic.
The use of preoperative gabapentin was associated with improved pain control and quality of life, without excessive side effects.

The purpose of the study was to determine whether calcium and magnesium infusions would prevent or ameliorate neurotoxity associated with oxaliplatin, enable a larger cumulative oxaliplatin dose delivered, ameliorate acute neuropathy associated with oxaliplatin, and whether any adverse events occurred.
Patients were randomly assigned to receive either IV calcium gluconate plus magnesium sulfate, 1 g each in 100 ml D5W for 30 minutes immediately before and after each dose of oxaliplatin, or an identical-looking placebo. Patients underwent a physical examination at study entry and before each two-week chemotherapy cycle, including an assessment for adverse events and toxicity as well as laboratory testing. Patients completed daily questionnaires before each dose of FOLFOX and for five days after completion of each cycle.
The study was conducted in multiple outpatient settings throughout the United States.
The study was a double-blind, placebo-controlled randomized clinical trial.
The study accrual was stopped before the original goal because of a data monitoring committee report regarding a similar trial in patients receiving palliative FOLFOX treatment in which interim analysis showed lower response rates in patients receiving calcium and magnesium. However, subsequent independent analysis of the data showed that initial interpretations were incorrect and that antitumor response was lower in that study's placebo group.
Results of the current study showed that the incidence of grade 2 or higher sensory neurotoxicity was significantly lower in the calcium and magnesium group on two different measurement scales (p < 0.04). In addition, onset of grade 2 or higher was significantly delayed in patients who received calcium and magnesium (p = 0.03). Patient report of numbness also was lower in the calcium and magnesium group (p = 0.021). The study intervention did not appear to have an effect of oxaliplatin-specific symptoms such as muscle cramps, throat discomfort, and cold sensitivity toxicities. No patients developed hypercalcemia.
The findings provide some support for the hypothesis that calcium and magnesium infusions can decrease oxaliplatin-related cumulative sensory neurotoxicity. The results suggest that some types of neurotoxic effects may be reduced, while no obvious effect on other symptoms is apparent.
Calcium and magnesium infusion may reduce neurotoxicity associated with chemotherapy agents. Additional research in this area is needed to determine if both elements are required and what is the most effective dosages, timing, and efficacy with agents other than oxaliplatin. Research would further clarify the role of this intervention with specific neuropathic symptoms and whether this intervention is effective with various chemotherapeutic agents.

To compare effects of a mindfulness-based intervention to those of a psychoeducational telephone consultation on quality of life, depression, fatigue, and anxiety.
The study was begun as a randomized, controlled trial and patients were allocated at random to either the mindfulness-based or psychoeducational groups. Because of patient complaints about group assignment, in the second half of the study, patients were allocated to the group of their choice. The mindfulness intervention was based on mindfulness-based stress reduction concepts and activities and was provided in 2.5-hour group sessions weekly for eight weeks. They also had homework assignments, two 2.5-hour booster sessions at the end of 1 and 2 months during a three-month follow-up phase, and an all-day retreat. At baseline, individuals were interviewed to establish individual goals and, at the end of the program, were interviewed regarding goal attainment, maintenance of acquired skills, and evaluation of personal experience. The comparison group received 15-30 minutes of psychoeducational consultations by telephone twice a month for eight weeks. During the follow-up period, they had additional phone calls at the end of months 1 and 2. Study measures were obtained two weeks before and after the initial intervention and three months postintervention. Consultation with intervention teachers was used to evaluate treatment fidelity.
Quality of life and depression improved immediately after the intervention (p < 0.02) At the three-month follow-up, significant differences were noted between groups, with improved quality of life in the mindfulness group (p = 0.04) and lower depressive symptoms and anxiety in the psychoed group (p = 0.04). There was no significant effect of either intervention on fatigue. There were no differences in outcomes based on whether the patient was randomly assigned or chose the preferred intervention.
Findings suggest that a mindfulness-based intervention may have positive benefits for overall quality of life and depressive symptoms in the short term, but this study did not show a long-term impact on depression or anxiety. No effect was seen for fatigue.
Findings suggest that a group mindfulness-based program for HCT survivors is feasible, although the overall attrition and poor attendance at follow-up sessions suggests it is difficult to maintain involvement in the longer term. Additional study incorporating Web-based and telephonic follow-up boosters might be more practical for patients to attend. Although there were some immediate effects for depressive symptoms, these were not long lasting. Additional research is needed to explore long-term benefits and most effective methods for delivery of this type of intervention.
