To determine the efficacy and safety of increasing opioid doses versus increasing doses of an adjuvant for patients with definite neuropathic cancer pain (i.e., neuropathic pain that occurred as a result of the disease, the treatment, or both). The goal was to achieve a 30% or more decrease in the visual analog scale (VAS) score compared to baseline.

One hundred and twenty patients were divided via simple randomization into two groups. Baseline data were collected on all 120 patients (i.e., VAS score, meds, and full assessment). The first group was prescribed a starting dose of pregabalin at 75 mg per day and titrated up by 75 mg every third day as needed up to 600 mg per day divided into two doses, until adequate pain relief was achieved or adverse effects were noted. The second group was given 25 mcg per hour fentanyl patch and increased by 25 mcg per hour every 72 hours up to a max dose of 150 mcg per hour until adequate pain relief was achieved or adverse events were noted. Both groups had rescue oral morphine as needed.

• N = 120  
• AGE = Older than 18 years
• MEAN AGE = Pregabalin group: 61.2 years (SD = 9.3 years); fentanyl group: 63.2 years (SD = 11.8 years)
• MALES = 58, FEMALES = 62
• KEY DISEASE CHARACTERISTICS: Diagnosed with definite neuropathic cancer pain
• OTHER KEY SAMPLE CHARACTERISTICS: On second step of the World Health Organization analgesic ladder; resistant to a combination of codeine with paracetamol; a non-steroidal anti-inflammatory drug and methylprednisolone used for a minimum of three consecutive days; expected survival of two months or longer; normal renal function and a VAS score greater than 4 at baseline

• SITE: Single site   
• SETTING TYPE: Not specified   
• LOCATION: Athens, Greece

• PHASE OF CARE: Mutliple phases of care
• APPLICATIONS: Elder care, palliative care

• Prospective, head-to-head, comparative, randomized, open-label

• Satisfaction Criterion (created by the authors for this study), which intended to define the level of pain relief considered appropriate for the study patients
•  VAS

Changes in VAS scores showed no difference between groups, but the percentage change in these scores showed a significant reduction for the patients on pregabalin (-58% versus -50%). A greater percentage of patients on pregabalin achieved the study primary endpoint of at least a 30% reduction in pain VAS score (73.3% with pregabalin, 36.7% with fentanyl, p < .0001). No significant difference was seen in the proportion of patients needing rescue medication.

For these patients with neuropathic pain, no significant differences were seen in efficacy of adjuvant pregabalin versus increasing opioid medication for pain control.

• Authors created their own measurement tool.
• Baseline VAS analysis was different between the two groups, with baseline  median pain lower in the opioid group—this could have made the defined reduction easier.
• Short timeframe (four weeks)
• The interventions compared involved two different routes of medication administration.
• The dose limit on fentanyl (150 mcg per hour) was based on the groups’ pain center protocol, which dictates that patients on more than 150 mcg per hour fentanyl would need to be considered for a different treatment or intervention.
• Limited information on any adverse events experienced by study participants
• No information about the amount of rescue medication used in both groups, only the proportion of patients that used any rescue medication

I find the results of this study to be useful for oncology professionals working with patients with neuropathic cancer pain, whether from the disease, the treatment, or both. A similar study using tramadol versus pregabalin for neuropathic cancer pain may be of value.

To evaluate the effects of 24 weeks of donepezil versus placebo on objectively measured cognitive function starting at least six months after whole- or partial-brain irradiation

This clinical trial tested donepezil at 5 mg daily for six weeks followed by 10 mg daily for 18 weeks compared to a placebo. Study outcome measurements were collected before randomization, and 12 and 24 weeks after randomization.

• N = 146
• MEDIAN AGE = 55 years (range = 20–84 years)
• MALES: 50%, FEMALES: 50%
• KEY DISEASE CHARACTERISTICS: 68% primary brain tumor (primary diagnosis was glioblastoma multiforme); 26% brain metastases from other primary tumor (primary diagnosis was lung cancer); 6% prophylactic cranial irradiation; 35% primarily frontal lobe involvement; median time since diagnosis was 40 months
• OTHER KEY SAMPLE CHARACTERISTICS: Pretreatment sample characteristics did not differ between groups. Most participants were married, white, had some college education, and had Eastern Cooperative Oncology Group scores of 0–1. Retention at the end of the trial was 74%, which did not differ between groups. Participants who dropped out had less education, lower income, smaller brain volume, and more hippocampal involvement.

• SITE: Multi-site
• SETTING TYPE: Outpatient
• LOCATION: Winston-Salem, NC, and Houston, TX

PHASE OF CARE: Late effects and survivorship

Randomized, double-blinded, placebo-controlled trial

• Hopkins Verbal Learning Test–Revised (HVLT-R)
• Modified Rey-Osterrieth Complex Figure
• Trail Making Test (TMT) parts A and B
• Controlled Oral Word Association Test (COWAT)
• Digit Span Test
• Grooved Pegboard Test

Self-reported adherence to the dose was approximately 92%, which did not differ between groups. The donepezil group reported more diarrhea (25%, p = 0.005) than the control. At baseline, both groups had poorer verbal memory, motor speed and dexterity, attention, and executive function compared to population norms. There was no improvement in overall cognitive function with 24 weeks of donepezil, but improvements were found for individual measures of memory (p = 0.007, 0.027) and motor speed and dexterity (p = 0.016). Donepezil showed greater improvement in overall cognitive function for patients with poorer cognitive function at baseline (p = 0.01).

For patients who received whole or partial brain irradiation, 24 weeks of donepezil improved memory and motor and speed dexterity. Greater improvements in multiple cognitive domains, including significant improvement in overall cognitive function, were found for patients with poorer cognitive function at baseline.

• Subject withdrawals ≥ 10%
• Most participants were white.

For patients who receive partial- or whole-brain irradiation for primary brain tumors or brain metastases, donepezil may improve memory and motor speed and dexterity. Patients with poorer cognitive function may have greater benefit, including improvement in overall cognitive function. Educate patients about the risk for diarrhea and appropriate management.

To assess the safety and efficacy of 180 mg rolapitant for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients with cancer who receive moderately or highly emetogenic chemotherapy (HEC)

Patients who had a KPS of 60 or higher, were expected to live at least four months, and had adequate bone marrow and liver and kidney function were randomly assigned to receive 180 mg of rolapitant versus placebo, which looked exactly like the rolapitant.

• N = 1,087 (from two identically designed global studies)
• MEAN AGE = 58.8 years
• MALES: 63%, FEMALES: 37%
• CURRENT TREATMENT: Chemotherapy
• KEY DISEASE CHARACTERISTICS Most common primary tumor was lung (44%), followed by head and neck (18%)
• OTHER KEY SAMPLE CHARACTERISTICS: Patients who had a KPS of 60 or higher, were expected to live at least four months, and had adequate bone marrow and liver and kidney function

PHASE OF CARE: Active antitumor treatment

This article describes two randomized, double-blind, active-control studies.

In both studies (and in the pooled results), treatment with rolapitant resulted in a significantly increased number of patients experiencing a complete response in the delayed phase. The pooled studies found significant difference in the acute phase (first 24 hours). In the overall phase, complete response was significantly more frequent in the first study and in the results of the pooled studies. No significant differences were observed between study groups with respect to daily living as measured by the FLI-E questionnaire.

Oral rolapitant taken once daily before chemotherapy in combination with a 5-HT₃ receptor antagonist and dexamethasone is superior to 5-HT₃ receptor antagonist and corticosteroid alone.

The study participants were enrolled prior to recommendations for the addition of an NK₁ receptor antagonist to standard care and the use of dexamethasone to HEC.

As now accepted, the addition of an NK₁ receptor antagonist reduces CINV experienced by patients receiving HEC. Patient education regarding adherence to medications and correct timing can help them prevent what is often the most worrisome side effect.

To determine the efficacy, safety, and tolerability of aprepitant for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients receiving moderately emetogenic chemotherapy (MEC) regimens and to determine if aprepitant would provide a complete response at preventing CINV in the first 5 days (120 hours) following chemotherapy

Patients naïve to moderately or highly emetogenic chemotherapy (HEC) and scheduled to receive a single dose of MEC agent, were enrolled in the study. Group one received an aprepitant triple-therapy regimen; group two received a control regimen that included a placebo 1 hour prior to chemotherapy, ondansetron (same dosing as aprepitant group), and dexamethasone on day 1, and, on days 2 and 3, placebo once daily and ondansetron twice daily (by mouth).

• The study looked at 848 participants.
• The mean age in years for patients receiving the aprepitant regimen was 57.1 (SD = 11.8 years); the mean age for patients receiving the control regimen was 55.9 (SD = 12.6 years).
• Diagnoses were 52% breast, 20% colon, 13% lung, and 4.6% ovarian.
• Chemotherapy regimens were 52% nonanthracycline/cyclophosphamide (n = 441) and 48% anthracycline/ cyclophosphamide (n = 407).
• More than two-thirds (69%) of participants were white.
• History of motion sickness was present in 5.6% of the aprepitant group and 9.8% of the control group.
• History of vomiting during pregnancy was present in 14.2% of the aprepitant group and 17.9% of the control group.

Studies were conducted at multiple sites in the United States, Mexico, Canada, Chile, Brazil, Peru, Colombia, Panama, Hong Kong, Australia, South Africa, France, Germany, Israel, and Russia.

Patients were in active treatment.

The study was a phase III, prospective, randomized, gender-stratified, double-blind trial.

Patients recorded the time and date of nausea, retching, and vomiting episodes in diaries. Nausea was assessed daily using a 100-mm horizontal visual analogue scale (VAS). If a rescue drug was used, the drug name and date and time of administration was recorded. Common Terminology of Adverse Events, version 3.0 (CTAE v 3.0) was used to assign toxicity grades to all laboratory test results and adverse events.

• The proportion of patients reporting no vomiting during the five days (0–120 hours) following initiation of chemotherapy was significantly higher in the aprepitant group (p < 0.001).
• In both the acute and delayed phases, significantly more patients in the aprepitant group reported no vomiting compared to the control group (p < 0.001).
• More patients in the aprepitant group reported a complete response in both the acute and delayed phases (p < 0.001), and time to first vomit was longer.
• No significant differences in the reporting of adverse events were found between groups.

The aprepitant regimen provided significantly more vomiting-free time. Better control with an aprepitant–containing, triple antiemetic regimen was seen for those receiving MEC (nonanthracycline and cyclophosphamide [AC] or AC).

• Results presented were for cycle one only.
• Limited generalizability is possible because the majority of the sample was female (77%) and Caucasian (69%).

Aprepitant was effective in preventing chemotherapy-associated vomiting in patients receiving a broad range of MEC and should be considered as part of a standard antiemetic regimen.

To evaluate the safety and efficacy of four different doses of rolapitant for the prevention of chemotherapy-induced nausea and vomiting (CINV) associated with cisplatin-based, highly emetogenic chemotherapy

Eligible patients were randomized to receive rolapitant at 9, 22.5, 90 or 180 mg or no rolapitant (active control) administered two hours before the first dose of chemotherapy on day 1 of cycle 1 with cisplatin greater than 70 mg/m². Patients also received Zofran^® at 32 mg IV and Decadron^® at 20 mg orally 30 minutes before chemotherapy. Dexamethasone was administered at 8 mg orally twice daily on days 2, 3, and 4.

• N = 454  
• MEDIAN AGE = 55 years (range = 18–86 years)
• MALES: 244 (54%), FEMALES: 210 (46%)
• KEY DISEASE CHARACTERISTICS: No disease characteristics were provided. Patients were receiving highly-emetogenic chemotherapy at 70 mg/m².
• OTHER KEY SAMPLE CHARACTERISTICS: Exclusions included patients who had previously received cisplatin, 5HT3 antagonists, NK1 antagonists, or other drugs that may interfere with the study five days prior to treatment. Patients who had abdominal or pelvis radiation scheduled on day 5 or 6 or were receiving systemic corticosteroids also were excluded.

Phase 2, randomized, double-blinded, active-controlled, parallel-group, dose-ranging study

• Patient diary with Visual Analog Scale (VAS) for nausea, emesis episodes, and use of rescue medication
• Functional Living Index-Emesis (FLIE) for quality of life
• Laboratory values, vital signs, electrocardiograms, and physical examinations for safety and tolerability

Rolapitant was well tolerated and was associated with greater complete response rates than the placebo group. Rolapitant at 180 mg achieved a statistically significant improvement compared to the active control group in the acute (87.6% and 66.7%, respectively, p = 0.001) and delayed (63.6% and 48.9%, respectively, p = 0.045) phases. Complete response rates across all phases of CINV were consistently higher for all other rolapitant dose groups compared to the active control group except the 9 mg group in the acute phase. However, this did not achieve statistical significance. Rolapitant also was statistically superior to the active control in other key secondary efficacy variables including less emesis in the acute and delayed phases and less nausea in the acute and delayed phases. Rolapitant at 90 and 180 mg doses significantly improved quality of life compared to the control group. The incidence of serious adverse events was similar in all treatment groups.

All doses of rolapitant were well tolerated and were associated with greater compete response rates than the active control (except 9 mg in the acute phase). Rolapitant at 180 mg demonstrated a clinical statistically significant effect in preventing CINV in the overall, acute, and delayed phases for patients receiving highly emetogenic chemotherapy.

In this study, rolapitant at 180 mg was safe, well tolerated, and effective in controlling CINV in all phases when given in combination with dexamethasone and a 5HT3 receptor antagonist for patients receiving highly emetogenic chemotherapy.

To explore the efficacy and safety of rolapitant in preventing chemotherapy-induced nausea and vomiting (CINV) over multiple cycles of moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC)

Patients were stratified by gender to receive either 180 mg oral rolapitant or placebo approximately 1–2 hours before receiving either MEC or HEC. All patients received a 5-HT₃ antiemetic and dexamethasone. Patients receiving MEC were given 2 mg oral granisetron on days 1–3 and 20 mg dexamethasone on day 1. Patients receiving HEC (e.g., cisplatin-based chemotherapy) were given 10 mc/kg granisetron intravenously and oral 20 mg dexamethasone on day 1 and 8 mg twice daily on days 2–4. Patients receiving taxanes were given dexamethasone per the package insert.

• KEY DISEASE CHARACTERISTICS: Patients were not recruited or stratified by specific tumor type. More than half of the patients (67%) had breast cancer.
• OTHER KEY SAMPLE CHARACTERISTICS: Inclusion criteria required that patients be aged 18 or older, have a Karnofsky score of 60 or better, have a life expectancy of four months or longer, and have adequate bone marrow, liver, and kidney functions. Patients in the MEC group were required to be naïve to MEC or HEC and scheduled to receive their first course of IV cyclophosphamide (< 1500 mg/m²), doxorubicin, epirubicin, carboplatin, idarubicin, ifosfamide, irinotecan, daunorubicin, and/or IV cytarabine (> 1 g/m²). At least 50% of the patients were to receive an AC-based (doxorubicin and cyclophosphamide) regimen. Patients in the HEC arm were required to be naïve to cisplatin and scheduled to receive their first course of cisplatin-based chemotherapy.

• SITE: Multi-site   
• SETTING TYPE: Not specified    
• LOCATION: Multinational—North, Central, and South America; Europe; Asia; and Africa

• PHASE OF CARE: Active antitumor treatment
• APPLICATIONS: Elder care

• Global, randomized, double-blind, placebo-controlled studies

Patients were given a diary to record all episodes of nausea, vomiting, and use of rescue drugs for five days post chemotherapy administration during cycle 1. For subsequent cycles, patients were asked two CINV assessment questions on days 6–8: (a) Have you had any episodes of vomiting or retching since your chemotherapy started in this cycle? and (b) Have you had any nausea since your chemotherapy started in this cycle that interfered with normal daily life? Assessments of safety variables, such as adverse events, vital signs, physical and neurological exams, electrocardiograms, and clinical lab values, were assessed during all cycles.

Compared to the control group, more patients receiving rolapitant reported no emesis or interfering nausea in cycles 2 (p = 0.006), 3 (p < 0.001), 4 (p = 0.001), and 5 (p = 0.021) when compared to the control group. Time to first emesis was significantly longer for the rolapitant group in cycles 1–6 (p < 0.001). The incidence of treatment-related adverse events were only slightly lower in the rolapitant (5.5%) than the control group (6.8%) during cycles 2–6.

Oral rolapitant was effective in protecting against CINV over multiple cycles of MEC and HEC. Rolapitant was well tolerated and demonstrated no increased frequency of adverse effects and no cumulative toxicity over multiple cycles.

Women were disproportionately high in the MEC study largely because of the high number of patients with breast cancer receiving AC chemotherapy.

The findings support the possible benefits of adding rolapitant to the therapy of patients receiving MEC and HEC.

To evaluate if Caphosol™ is effective to treat oral mucositis (OM) in pediatric patients who received chemotherapy or hematopoietic stem cell transplant (HSCT)

A sample of 33 patients between 4–18 years old was assigned to Caphosol or placebo. All patients received standard local supportive care, in addition to Caphosol study or 0.9% sodium chloride (NaCl) placebo mouth rinse. All patients were instructed to use the study mouthwash four times daily during their OM period. Primary study outcome was defined as the number of days with OM greater than grade 1. Secondary outcomes were pain and analgesic use.

• N = 29
• AGE RANGE: 4–18 years
• MALES: 66%, FEMALES: 34%
• KEY DISEASE CHARACTERISTICS: Patients had been diagnosed with hematologic malignancies, solid tumor, and benign hematologic disorders and were receiving chemotherapy or HSCT.

• SITE: Multi-site
• SETTING TYPE: Inpatient
• LOCATION: Four university hospitals in the Netherlands

• PHASE OF CARE: Active antitumor treatment
• APPLICATIONS: Pediatrics

• Double-blinded, placebo-controlled trial

• The National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 3.0 mucositis scoring system was used to evaluate mucositis.
  • Days of mucositis greater than grade 1 and peak level of mucositis
  • Days of pain and peak of level pain
  • Days of analgesic use, morphine use, peak dose (mg/kg)
  • Need for tube feeding and number of days
  • Need for parenteral feeding and number of days
  • Blood cultures taken

Chi-square or t-test was used for analysis. The number of days with mucositis greater than grade 1 did not differ significantly between the two study groups (p = 0.154). No significant differences were found between Caphosol and placebo for all the outcome measures except days of pain and tube feeding requirement. Placebo was associated with significantly fewer days of pain (p = 0.035) . The need for tube feeding was significantly higher in the Caphosol group.

Therapeutic use of Caphosol was not beneficial in the treatment of pediatric patients with cancer therapy-induced OM.

• Small sample (< 30)
• Risk of bias (sample characteristics)
• Key sample group differences could influence results.
• Findings not generalizable
• High grades of mucositis were found at the start of the study with 64.3 % of the placebo group versus 33.3 % of the patients with Caphosol having greater than grade 1 mucositis at the start of the study (p = 0.143). The placebo group also showed a trend of shorter mucositis duration, which may suggest that mucositis was more advanced at baseline and resolved earlier. This, in turn, may have contributed to the finding that the placebo group had fewer days with mucositis greater than grade 1.
• A problem was seen with a power calculation, and many analyses failed to demonstrate significant results. This study has significant risk for type II errors. In addition, this study included various types of cancer and cancer treatments, which may have contributed to the lack of significance in findings.

Although this study was a double-blind, randomized, controlled trial, the significantly small sample size was problematic. The authors concluded that Caphosol was not effective in practice; however, it is not conclusive because of the significantly high risk for type II errors. A study with a larger sample size is required to assess the efficacy of Caphosol.

The purpose of the study was to evaluate the effect of gabapentin on chemotherapy-induced peripheral neuropathy (CIPN).

Patients were assigned to either one of two groups: gabapentin followed by placebo or placebo followed by gabapentin. Doses of both capsules were incrementally increased during the course of three weeks to a target does of 2,700 mg. Patients were treated for six weeks and then had a two-week washout period. After the washout period, patients were treated for another six weeks in the crossover. The sample size was determined by power analysis and study measures were obtained weekly.

• The sample consisting of 68 participants with a mean age of 59 years and a range of 25–84 years.
• Women outnumbered men, 73%–27%, respectively.
• Specific diagnoses were not described by the authors, but 50% of the participants were on active treatment at the time of the study.
• All patients had symptom severity of 4 or greater on a numerical rating scale for peripheral neuropathic pain.
• Patients were receiving vinca alkaloids, taxanes, cisplatin-based compounds, or some combination of these.

The study was conducted at multiple outpatient settings in the north-central region of the United States.

• A numeric rating scale of 0-10 for pain.
• The World Health Organization classification scale for neuropathic symptoms (parasthesias, tendon reflexes, weakness, motor loss included).
• The short form McGill pain questionnaire.
• The Brief Pain Inventory.
• A symptom distress scale (five point).
• The Profiles of Mood States.

The McGill pain rating questionnaire at six weeks indicated lower pain in the gabapentin-treated groups. No other differences were noted between groups at any point in time during the study. On the numerical scale, a slight reduction in pain was seen in all participants. Improvement was highest in patients who had higher baseline average pain and in those currently in active chemotherapy treatment.  Most frequent adverse events were dizziness and fatigue and no differences in adverse events were noted based on gabapentin treatment.

The findings failed to demonstrate any benefit in using gabapentin for CIPN.

• Limitations included a sample size of less than 100 participants.
• A 41% dropout rate occurred, which was not discussed.
• Because of the dropouts, the sample size in the final analysis was underpowered.
• No intention-to-treat analysis was reported and no mention was made of other medications used to treat pain.

The findings do not support the use of gabapentin for the management of CINV.

To compare effects of a 24-week yoga program with those of a supportive therapy control intervention in patients with early breast cancer

Prior to surgery, patients were assessed and randomly assigned to the yoga program intervention or control condition. All patients received 50 cGy of radiation therapy over six weeks and were prescribed six cycles of standard chemotherapy with the same schedule. Patients in both groups received alpraxolam 0.5 mg once daily for one week following chemotherapy for the first one to two chemotherapy cycles. Patients in the yoga group had four in-person sessions during the perioperative period and were to undergo three in-person sessions per week for six weeks during radiotherapy treatment, with self-practice on the remaining days. During chemotherapy, patients had in-person sessions during visits (one per 21 days) and in-person sessions with a trainer every 10 days. The instructor monitored self-practice through telephone calls and house visits. The control intervention was brief supportive therapy with education, including 15-minute counseling sessions every 10 days during treatment by a social worker. All patients were asked to maintain daily diaries of symptoms, medication, and diet intake, and for those in the yoga group, their frequency and duration of yoga practice.

• The study reported on a sample of 38 female patients.
• Age information was not reported.
• All patients had early-stage breast cancer, and 51% were postmenopausal.
• Of the total sample, 28% reported having other stressful life events in the past two years.

• Single site
• Inpatient and outpatient setting
• India

Patients were undergoing the active treatment phase of care.

A randomized controlled trial design was used.

• State-Trait Anxiety Inventory: symptom grading on 0–4 Likert-type scale
• Patient diary

Sixty-one percent of patients initially randomized dropped out of the study. Approximately half of these patients decided to leave the study after initial surgery, and the rest of the dropouts were removed from the study because they did not end up receiving the same expected adjuvant treatment sequence. Anxiety declined over time in all patients, and overall ANOVA did not show a significant group and time effect. Post hoc analysis showed that the yoga group had significantly lower anxiety immediately postsurgery and midway through radiation therapy (p < 0.05) and midway through chemotherapy (p < 0.001). Analysis of overall symptom distress showed a significant effect of the yoga group over time for reduction in symptom distress (p = 0.001). Post hoc testing showed a significant decrease in trait anxiety in the yoga group compared to controls at several time points in the study (p < 0.01). The effect size for state anxiety was 0.33. Anxiety and symptom distress were strongly correlated at all phases of treatment, with r ranging from 0.49 to 0.73 (p < 0.05).

Anxiety decreased over time in all patients. The yoga intervention was associated with a significantly greater reduction in anxiety at several time points in the treatment schedule, immediately following surgery, midway through radiation therapy, and midway through chemotherapy.

• The study had a small sample size, with less than 100 participants. Although small, the sample size was based on power analysis, but assumed a larger anxiety effect size than found in this study.
• The study had a very high drop-out rate. Intention to treat analysis was done using baseline measures for dropouts, resulting in much less change in outcomes seen, which was not particularly helpful in attempting to evaluate the effects of participation in the intervention. The control condition did provide some patient attention, but it was much less than that received by the intervention group.
• The study did not include information regarding actual patient adherence to self-directed yoga practice.
• Potential risk of bias exists due to no blinding.

Yoga as provided in this study, with individual instructor-directed sessions and patient self-guided practice expectations, had a mild effect in reducing anxiety over time during various phases of cancer treatment. Guided sessions were done at scheduled visits for treatment, suggesting that this can be a practical way to facilitate patient participation. Patients may find yoga helpful to reduce stress and anxiety.

Patients were randomized to either lamotrigine or placebo. Sixty-three patients were randomized to lamotrigine and 62 to placebo. The dose was escalated from 25 mg at bedtime to 150 mg twice daily, a regimen that continued for two weeks. Ten weeks after drug initiation, patients tapered off lamotrigine or placebo over a four-week period.

• The study had a total sample size of 125 patients.
• Patients were treated with neurotoxic chemotherapy.
• Patients were symptomatic for chemotherapy-induced peripheral neuropathy for one month or more, with a daily average pain score of 4 or greater on a 10-point scale or greater than 1 on the Eastern Cooperative Oncology Group Grading Scale for CIPN.

Phase III randomized, double-blind, placebo-controlled trial

• Investigators conducted assessments weekly. A numeric rating scale measured average daily pain scores.
• Secondary measures included the World Health Organization Classification Scale, which rated neuropathy symptoms from 0 (none) to 4 (paralysis).
• The Short-Form McGill Pain questionnaire assessed characteristics of pain (throbbing, stabbing, etc.).
• The Brief Pain Inventory (Short Form) assessed the effect of pain on functional ability.
• The Subjective Global Assessment measured change in overall symptoms from no change to much worse.
• The Symptom Distress Scale, a five-point scale, measured common cancer-related symptoms.
• The Profile of Mood States Short Form, a 30-item scale, measured mood states.
• A single-item tool with a scale 0–100 measured quality of life.
• The Eastern Cooperative Oncology Group Grading Scale for CIPN, a 10-point scale, measured specific pain qualities.
• Investigators used National Cancer Institute common toxicity criteria to grade toxicity.

A total of 125 patients enrolled, but only 80 completed the study. Authors observed no significant differences between the two groups in the pain scale or the ENS.

Lamotrigine was not effective in relieving chemotherapy-induced peripheral neuropathy.

• The sample was mixed, including different levels of chemotherapy-induced peripheral neuropathy, cancer treatments received, cancer diagnoses, and length of time since treatment completion.
• Many primary and secondary outcomes were tested.
• Authors did not account for the use of an error rate of only 2.5% or for stratification procedures by type of neurotoxic regimen. Sampling estimations increased the chance of statistical error.
