A phase 2 study of stereotactic body radiation therapy for squamous cell carcinoma of the head and neck (SHINE): a single arm clinical trial protocol.

BACKGROUND: Cancers of the head and neck region are often characterized by locally advanced, non-metastatic disease. Standard treatments for advanced cervico-facial cancers of the skin or primary head and neck squamous cell carcinoma (HNSCC) include combinations of surgery, radiation and chemotherapy, which are associated with high rates of acute toxicity and complications. Stereotactic body radiotherapy (SBRT) has been shown to be a promising modality of treatment for this patient population in retrospective studies; to our knowledge, there are no prospective clinical studies evaluating the safety and efficacy of SBRT in these patients. METHODS: This phase 2, single institution, single arm study aims to evaluate response rates to SBRT in older age patients with locally advanced HNSCC for whom primary surgery is not recommended or performed. The intervention is SBRT 45 Gy in 5 fractions given every 3-4 days. Toxicity, quality of life and patient outcomes will be recorded regularly up to 24 months after completion of SBRT. DISCUSSION: For this patient population, SBRT may offer a shorter and more effective treatment than the current standard of care palliative regimens. If the study demonstrates that SBRT is safe and effective, then this may lead to randomized studies comparing conventional radiotherapy to SBRT for selected head and neck cancer patients.

Exploratory Factor Analysis of NRG Oncology's University of Washington Quality of Life Questionnaire-RTOG Modification.

CONTEXT: The 15-item University of Washington Quality of Life questionnaire-Radiation Therapy Oncology Group (RTOG) modification (UW-QOL-RTOG modification) has been used in several trials of head and neck cancer conducted by NRG Oncology such as RTOG 9709, RTOG 9901, RTOG 0244, and RTOG 0537. OBJECTIVES: This study is an exploratory factor analysis (EFA) to establish validity and reliability of the instrument subscales. METHODS: EFA on the UW-QOL-RTOG modification was conducted using baseline data from NRG Oncology's RTOG 0537, a trial of acupuncture-like transcutaneous electrical nerve stimulation in treating radiation-induced xerostomia. Cronbach α coefficient was calculated to measure reliability; correlation with the University of Michigan Xerostomia Related Quality of Life Scale was used to evaluate concurrent validity; and correlations between consecutive time points were used to assess test-retest reliability. RESULTS: The 15-item EFA of the modified tool resulted in 11 items split into four factors: mucus, eating, pain, and activities. Cronbach α ranged from 0.71 to 0.93 for the factors and total score, consisting of all 11 items. There were strong correlations (ρ ≥ 0.60) between consecutive time points and between total score and the Xerostomia Related Quality of Life Scale total score (ρ > 0.65). CONCLUSION: The UW-QOL-RTOG modification is a valid tool that can be used to assess symptom burden of head and neck cancer patients receiving radiation therapy or those who have recently completed radiation. The modified tool has acceptable reliability, concurrent validity, and test-retest reliability in this patient population, as well as the advantage of having being shortened from 15 to 11 items.

Phase 2 Study of Acupuncture-Like Transcutaneous Nerve Stimulation for Chemotherapy-Induced Peripheral Neuropathy.

A prospective phase 2 study was conducted to evaluate the clinical utility of acupuncture-like transcutaneous nerve stimulation (ALTENS) for the treatment of chemotherapy-induced peripheral neuropathy (CIPN). Eligible cancer patients had a < 2 ECOG performance score, received neurotoxic chemotherapy, and developed CIPN symptoms for > two months. Randomization was used to eliminate bias in patient selection for ALTENS and was not to compare the effectiveness between the two treatments.ALTENS treatments were delivered using Codetron units. Bilateral acupuncture points included LI4 and LIV3, plus LI11 or ST36 were stimulated. Acupuncture treatments were administered to CV6, SP6, ST6, LI11, Bafeng, Baxie and selective Jing points bilaterally. Twelve treatments were delivered twice weekly over 6 to 8 weeks. The Modified Total Neuropathy Score (mTNS), Numbness Score, and Edmonton Symptom Assessment Score (ESAS) were assessed at baseline, treatment completion, plus at 3 and 6 months follow-up. The primary study endpoint was mTNS score at 6 months. We planned to recruit 23 patients into each group. After 30 patients were recruited, 2 were lost to follow-up at 3 months in the ALTENS group and 3 in the acupuncture group. The research team decided to recruit all remaining consecutive patients only to the ALTENS group to ensure an adequate evaluation of ALTENS, the primary object of evaluation. There were 27 patients in the ALTENS group, with an average symptom duration of 10 months after chemotherapy. Twenty four and 23 patients completed the 3 and 6 month follow-up respectively. The median mTNS scores were 7.1, 4.0, 3.6 and 3.1 at baseline, treatment completion, 3 and 6 months follow-up, respectively. One-way ANOVA analysis showed a significant improvement in mTNS scores (p<0.001) at 6 months. Numbness scores were also significantly improved at 6 months. ESAS pain scores and perception of well-being scores analyses were inconclusive. There were no significant reported side effects of ALTENS. There were only 13 patients in the acupuncture group and the number was insufficient for either an independent or a comparative analysis. The results of this study suggests that ALTENS significantly reduces the mTNS scores and numbness in patients suffering from CIPN symptoms.

Xerostomia health-related quality of life: NRG oncology RTOG 0537.

PURPOSE: The purpose of this secondary analysis was to determine change in overall health-related quality of life (HRQOL) based on patient data obtained from NRG Oncology RTOG 0537 as measured by the RTOG-modified University of Washington Head and Neck Symptom Score (RM-UWHNSS). METHODS: A multi-site prospective randomized clinical trial design stratified 137 patients with post-radiation therapy xerostomia according to prior pilocarpine (PC) treatment and time after radiation therapy and/or chemotherapy and randomized patients into two groups. Patients were assigned to acupuncture or PC. Twenty-four sessions of acupuncture-like transcutaneous electrical nerve stimulation (ALTENS) were administered over 12 weeks, or oral PC (5 mg) three times daily over the same 12 weeks. The RM-UWHNSS was administered at baseline and at 4, 6, 9, and 15 months after the date of randomization. RESULTS: There were no between-arm differences in change scores on the RM-UWHNSS in the individual items, total score, or factor scores. For statistical modeling, race and time were significant for all outcomes (total and factor scores), while treatment arm was not significant. The ALTENS arm showed greater yet nonsignificant improvement in outcomes compared to the PC arm. CONCLUSION: Although no significant treatment differences were seen in this trial, patients receiving ALTENS consistently had lower scores, indicating better function, as compared to those receiving PC. Radiation-induced xerostomia improved over time for all patients.

Acupuncture-Like Transcutaneous Electrical Nerve Stimulation Versus Pilocarpine in Treating Radiation-Induced Xerostomia: Results of RTOG 0537 Phase 3 Study.

PURPOSE AND OBJECTIVES: This report presents the analysis of the RTOG 0537 multicenter randomized study that compared acupuncture-like transcutaneous stimulation (ALTENS) with pilocarpine (PC) for relieving radiation-induced xerostomia. METHODS AND MATERIALS: Eligible patients were randomized to twice-weekly 20-minute ALTENS sessions for 24 sessions during 12 weeks or PC (5 mg 3 times daily for 12 weeks). The primary endpoint was the change in the University of Michigan Xerostomia-Related Quality of Life Scale (XeQOLS) scores from baseline to 9 months from randomization (MFR). Secondary endpoints included basal and citric acid primed whole salivary production (WSP), ratios of positive responders (defined as patients with ≥20% reduction in overall radiation-induced xerostomia symptom burden), and the presence of adverse events based on the Common Terminology Criteria for Adverse Events version 3. An intention-to-treat analysis was conducted. RESULTS: One hundred forty-eight patients were randomized. Only 96 patients completed the required XeQOLS and were evaluable at 9 MFR (representing merely 68.6% statistical power). Seventy-six patients were evaluable at 15 MFR. The median change in the overall XeQOLS in ALTENS and PC groups at 9 and 15 MFR were -0.53 and -0.27 (P=.45) and -0.6 and -0.47 (P=.21). The corresponding percentages of positive responders were 81% and 72% (P=.34) and 83% and 63% (P=.04). Changes in WSP were not significantly different between the groups. Grade 3 or less adverse events, mostly consisting of grade 1, developed in 20.8% of patients in the ALTENS group and in 61.6% of the PC group. CONCLUSIONS: The observed effect size was smaller than hypothesized, and statistical power was limited because only 96 of the recruited 148 patients were evaluable. The primary endpoint-the change in radiation-induced xerostomia symptom burden at 9 MFR-was not significantly different between the ALTENS and PC groups. There was significantly less toxicity in patients receiving ALTENS.

Patient-centered care in cancer treatment programs: the future of integrative oncology through psychoeducation.

The reciprocal relationship between the mind and body has been a neglected process for improving the psychosocial care of cancer patients. Emotions form an important link between the mind and body. They play a fundamental role in the cognitive functions of decision-making and symptom control. Recognizing this relationship is important for integrative oncology. We define psychoeducation as the teaching of self-evaluation and self-regulation of the mind-body process. A gap exists between research evidence and implementation into clinical practice. The patients' search for self-empowerment through the pursuit of complementary therapies may be a surrogate for inadequate psychoeducation. Integrative oncology programs should implement psychoeducation that helps patients to improve both emotional and cognitive intelligence, enabling them to better negotiate cancer treatment systems.

Randomized trial of hyperfractionation versus conventional fractionation in T2 squamous cell carcinoma of the vocal cord (RTOG 9512).

PURPOSE: To compare hyperfractionation versus standard fractionation for T2N0 vocal cord carcinoma in a randomized controlled trial. METHODS AND MATERIALS: Patients with T2 vocal cord cancer were stratified by substage (T2a vs T2b) and randomly assigned to receive either hyperfractionation (HFX) to 79.2 Gy in 66 fractions of 1.2 Gy given twice a day, or standard fractionation (SFX) to 70 Gy in 35 fractions given once a day. The trial was designed to detect a 55% reduction in the local failure hazard rate with 80% statistical power. RESULTS: Between April 1996 and July 2003, a total of 250 patients were enrolled. Of 239 patients analyzable for outcomes, 94% were male, 83% had a Karnofsky performance status of 90-100, and 62% had T2a tumor. Median follow-up for all surviving patients was 7.9 years (range, 0.6-13.1 years). The 5-year local control (LC) rate was 8 points higher but not statistically significant (P=.14 for HFX [78%] vs SFX [70%]), corresponding to a 30% hazard rate reduction. The 5-year disease-free survival (DFS) was 49% versus 40% (P=.13) and overall survival (OS) was 72% versus 63% (P=.29). HFX was associated with higher rates of acute skin, mucosal, and laryngeal toxicity. Grade 3-4 late effects were similar with a 5-year cumulative incidence of 8.5% (3.4%-13.6%) after SFX and 8.5% (3.4%-13.5%) after HFX. CONCLUSIONS: The 5-year local control was modestly higher with HFX compared to SFX for T2 glottic carcinoma, but the difference was not statistically significant. These results are consistent with prior studies of hyperfractionation showing a benefit in local control. Substaging by T2a versus T2b carries prognostic value for DFS and OS. For cost and convenience reasons other altered fractionation schedules have been adopted in routine practice.

Flax and Breast Cancer: A Systematic Review.

BACKGROUND: Flax is a food and dietary supplement commonly used for menopausal symptoms. Flax is known for its lignan, α-linolenic acid, and fiber content, components that may possess phytogestrogenic, anti-inflammatory, and hormone modulating effects, respectively. We conducted a systematic review of flax for efficacy in improving menopausal symptoms in women living with breast cancer and for potential impact on risk of breast cancer incidence or recurrence. METHODS: We searched MEDLINE, Embase, the Cochrane Library, and AMED from inception to January 2013 for human interventional or observational data pertaining to flax and breast cancer. RESULTS: Of 1892 records, we included a total of 10 studies: 2 randomized controlled trials, 2 uncontrolled trials, 1 biomarker study, and 5 observational studies. Nonsignificant (NS) decreases in hot flash symptomatology were seen with flax ingestion (7.5 g/d). Flax (25 g/d) increased tumor apoptotic index (P< .05) and decreased HER2 expression (P< .05) and cell proliferation (Ki-67 index; NS) among newly diagnosed breast cancer patients when compared with placebo. Uncontrolled and biomarker studies suggest beneficial effects on hot flashes, cell proliferation, atypical cytomorphology, and mammographic density, as well as possible anti-angiogenic activity at doses of 25 g ground flax or 50 mg secoisolariciresinol diglycoside daily. Observational data suggests associations between flax and decreased risk of primary breast cancer (adjusted odds ratio [AOR] = 0.82; 95% confidence interval [CI] = 0.69-0.97), better mental health (AOR = 1.76; 95% CI = 1.05-2.94), and lower mortality (multivariate hazard ratio = 0.69; 95% CI = 0.50-0.95) among breast cancer patients. CONCLUSIONS: Current evidence suggests that flax may be associated with decreased risk of breast cancer. Flax demonstrates antiproliferative effects in breast tissue of women at risk of breast cancer and may protect against primary breast cancer. Mortality risk may also be reduced among those living with breast cancer.

Black cohosh and breast cancer: a systematic review.

BACKGROUND: Many women use black cohosh as a natural treatment for menopausal symptoms. However, controversy exists around safety in breast cancer, because of its purported estrogenic activity. We conducted a systematic review of black cohosh use in women with or at risk of breast cancer. METHODS: We searched MEDLINE, Embase, the Cochrane Library, and AMED from inception to July 2012 and October 2012 for human interventional or observational data pertaining to the safety and efficacy of black cohosh in patients with or at risk of breast cancer, including an assessment of the effect of black cohosh on estrogen responsive tissues. RESULTS: Of 450 records, we included 26 articles: 14 randomized controlled trials, 7 uncontrolled trials, and 5 observational studies.The evidence on efficacy for ho t flashes is divided, with some benefits seen when compared with baseline, but not when compared with placebo. Two observational studies found no association between black cohosh and risk of breast cancer, whereas 2 studies reported significant reductions in risk of primary breast cancer among postmenopausal women (adjusted odds ratio = 0.47, 95% confidence interval = 0.27-0.82), and risk of recurrence (adjusted hazard ratio = 0.75, 95% confidence interval = 0.63-0.89). Seventeen trials showed no significant impact on circulating hormone levels or proliferation in estrogen responsive tissues. CONCLUSIONS: Current evidence does not support an association between black cohosh and increased risk of breast cancer. There is a lack of evidence supporting the efficacy of black cohosh for reduction of hot flashes in breast cancer patients. Given conflicting but promising results, and apparent safety, further research is warranted.

Soy, red clover, and isoflavones and breast cancer: a systematic review.

BACKGROUND: Soy and red clover isoflavones are controversial due to purported estrogenic activity and possible effects on breast cancer. We conducted a systematic review of soy and red clover for efficacy in improving menopausal symptoms in women with breast cancer, and for potential impact on risk of breast cancer incidence or recurrence. METHODS: We searched MEDLINE, Embase, the Cochrane Library, and AMED from inception to March 2013 for human interventional or observational data pertaining to the safety and efficacy of soy and red clover isoflavones in patients with or at risk of breast cancer. RESULTS: Of 4179 records, we included a total of 131 articles: 40 RCTs, 11 uncontrolled trials, and 80 observational studies. Five RCTs reported on the efficacy of soy for hot flashes, showing no significant reductions in hot flashes compared to placebo. There is lack of evidence showing harm from use of soy with respect to risk of breast cancer or recurrence, based on long term observational data. Soy intake consistent with that of a traditional Japanese diet (2-3 servings daily, containing 25-50mg isoflavones) may be protective against breast cancer and recurrence. Human trials show that soy does not increase circulating estradiol or affect estrogen-responsive target tissues. Prospective data of soy use in women taking tamoxifen does not indicate increased risk of recurrence. Evidence on red clover is limited, however existing studies suggest that it may not possess breast cancer-promoting effects. CONCLUSION: Soy consumption may be associated with reduced risk of breast cancer incidence, recurrence, and mortality. Soy does not have estrogenic effects in humans. Soy intake consistent with a traditional Japanese diet appears safe for breast cancer survivors. While there is no clear evidence of harm, better evidence confirming safety is required before use of high dose (≥ 100 mg) isoflavones can be recommended for breast cancer patients.

Sweet bee venom pharmacopuncture for chemotherapy-induced peripheral neuropathy.

INTRODUCTION: Chemotherapy-induced peripheral neuropathy (CIPN) is sensory and motor nerve damage to the peripheral nervous system caused by chemotherapeutic agents. It often causes pain and other varying degrees of neuropathic symptoms accompanied by functional limitations and reduced quality of life. Currently, there is no standard treatment protocol for the treatment of CIPN. OBJECTIVE: In need of more research to develop new therapeutic options focusing on their safety, efficacy, and long-term sustained clinical effects, a pilot study of sweet bee venom pharmacopuncture (SBVP) for CIPN was conducted to build up preliminary efficacy data in the process of preparing for a future larger scale randomized controlled SBVP trial for CIPN. METHODS: We conducted a prospective case series by analyzing the clinical observations made of CIPN patients treated with SBVP. A total of 11 eligible consecutive CIPN patients who visited East-West Cancer Center from June 1, 2010, to February 28, 2011, were treated with total of six SBVP treatments given within the 3-week period. The outcomes were measured using World Health Organization Common Toxicity Criteria for Peripheral neuropathy (WHO grading system), Patient Neurotoxicity Questionnaire (PNQ), Visual Analogue System (VAS), and Health-Related Quality of Life (HRQOL) collected at the baseline, post-second, fourth, and the final treatment. Patients were followed 3 weeks into no intervention to determine the sustained effects of pharmacopuncture. RESULTS: Both of the WHO CIPN grade and PNQ scores have shown a decrease in the level of neuropathy. VAS pain level has also shown a great decrease and improvement in patients' quality of life have also been detected though modest. Changes in WHO grade, VAS and Total HRQOL scores between the baseline and after the last treatment session were significant. Changes in WHO grade, Total PNQ, PNQ-sensory, VAS, Total HRQOL, and HRQOL-functional scores between the baseline and the 3-week follow-up were significant. CONCLUSION: The positive result of the study supports the potential value of conducting a fully powered trial to explore further efficacy of SBVP for CIPN. However a single positive result within this pilot study must be interpreted with caution.

Phase II trial of radiosurgery to magnetic resonance spectroscopy-defined high-risk tumor volumes in patients with glioblastoma multiforme.

PURPOSE: To determine the efficacy of a Gamma Knife stereotactic radiosurgery (SRS) boost to areas of high risk determined by magnetic resonance spectroscopy (MRS) functional imaging in addition to standard radiotherapy for patients with glioblastoma (GBM). METHODS AND MATERIALS: Thirty-five patients in this prospective Phase II trial underwent surgical resection or biopsy for a GBM followed by SRS directed toward areas of MRS-determined high biological activity within 2 cm of the postoperative enhancing surgical bed. The MRS regions were determined by identifying those voxels within the postoperative T2 magnetic resonance imaging volume that contained an elevated choline/N-acetylaspartate ratio in excess of 2:1. These voxels were marked, digitally fused with the SRS planning magnetic resonance image, targeted with an 8-mm isocenter per voxel, and treated using Radiation Therapy Oncology Group SRS dose guidelines. All patients then received conformal radiotherapy to a total dose of 60 Gy in 2-Gy daily fractions. The primary endpoint was overall survival. RESULTS: The median survival for the entire cohort was 15.8 months. With 75% of recursive partitioning analysis (RPA) Class 3 patients still alive 18 months after treatment, the median survival for RPA Class 3 has not yet been reached. The median survivals for RPA Class 4, 5, and 6 patients were 18.7, 12.5, and 3.9 months, respectively, compared with Radiation Therapy Oncology Group radiotherapy-alone historical control survivals of 11.1, 8.9, and 4.6 months. For the 16 of 35 patients who received concurrent temozolomide in addition to protocol radiotherapeutic treatment, the median survival was 20.8 months, compared with European Organization for Research and Treatment of Cancer historical controls of 14.6 months using radiotherapy and temozolomide. Grade 3/4 toxicities possibly attributable to treatment were 11%. CONCLUSIONS: This represents the first prospective trial using selective MRS-targeted functional SRS combined with radiotherapy for patients with GBM. This treatment is feasible, with acceptable toxicity and patient survivals higher than in historical controls. This study can form the basis for a multicenter, randomized trial.

Phase 2 results from Radiation Therapy Oncology Group Study 0537: a phase 2/3 study comparing acupuncture-like transcutaneous electrical nerve stimulation versus pilocarpine in treating early radiation-induced xerostomia.

BACKGROUND: In this phase 2 component of a multi-institutional, phase 2/3, randomized trial, the authors assessed the feasibility and preliminary efficacy of acupuncture-like transcutaneous electrical nerve stimulation (ALTENS) in reducing radiation-induced xerostomia. METHODS: Patients with cancer of the head and neck who were 3 to 24 months from completing radiotherapy with or without chemotherapy (RT ± C) and who were experiencing xerostomia symptoms with basal whole saliva production ≥0.1 mL per minute and were without recurrence were eligible. Patients received twice weekly ALTENS sessions (24 sessions over 12 weeks) using a proprietary electrical stimulation unit. The primary study objective was to assess the feasibility of ALTENS treatment. Patients were considered compliant if 19 of 24 ALTENS sessions were delivered, and the targeted compliance rate was 85%. Secondary objectives measured treatment-related toxicities and the effect of ALTENS on overall radiation-induced xerostomia burden using the University of Michigan Xerostomia-Related Quality of Life Scale (XeQOLS). RESULTS: Of 48 accrued patients, 47 were evaluable. The median age was 60 years, 84% of patients were men, 70% completed RT ± C for >12 months, and 21% had previously received pilocarpine. Thirty-four patients completed all 24 ALTENS sessions, 9 patients completed 20 to 23 sessions, and 1 patient completed 19 sessions, representing a 94% total compliance rate. Six-month XeQOLS scores were available for 35 patients and indicated that 30 patients (86%) achieved a positive treatment response with a mean ± standard deviation reduction of 35.9% ± 36.1%. Five patients developed grade 1 or 2 gastrointestinal toxicity, and 1 had a grade 1 pain event. CONCLUSIONS: The current results indicated that ALTENS treatment for radiation-induced xerostomia can be delivered uniformly in a cooperative, multicenter setting and produces possible beneficial treatment response. Given these results, the phase 3 component of this study was initiated.

Acute-phase response reactants as objective biomarkers of radiation-induced mucositis in head and neck cancer.

BACKGROUND: Current evaluation of radiation-induced mucositis in head and neck cancer relies on subjective scoring with interrater variability. We evaluated serum erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) as objective markers of radiation-induced mucositis. METHODS: Weekly serum CRP and ESR levels were measured in patients treated for head and neck cancer with radiation ± chemotherapy. Acute radiation toxicity was evaluated using National Cancer Institute of Canada-Common Toxicity Criteria (NCIC-CTC) version 2.0 and the Head and Neck Radiotherapy Questionnaire (HNRQ). RESULTS: ESR and CRP levels were significantly elevated by 3 weeks (p = .01) and 6 weeks (p = .0002), respectively, and independent of age or pretreatment surgery. ESR was significantly dependent on radiation dose (p = .0004) and significantly higher with chemoradiation (p = .03). CONCLUSION: Serum ESR and CRP rise reliably in a radiation dose-dependent manner. ESR correlated with clinical symptoms and distinguished patients receiving chemoradiation. ESR and CRP may be an objective and sensitive marker of radiation-induced mucositis.

Systems modeling in integrative oncology.

Systems modeling provides an integrated framework to capture and analyze diverse and multidisciplinary data in a standardized manner. The authors present the Integrative Oncology Systems Model (IOSM) to help assess the impact of behavior modification and various therapeutic interventions on cancer development and progression and the resultant effect on survival and quality of life outcomes.

Effects of sweet bee venom pharmacopuncture treatment for chemotherapy-induced peripheral neuropathy: a case series.

OBJECTIVE: This is a case series reporting safety and degree of response to 1 dose level of sweet bee venom pharmacopuncture (SBVP) or melittin as a symptom-control therapy for chemotherapy-induced peripheral neuropathy (CIPN). SETTING: All treatments were conducted at the East West Cancer Center (EWCC), Dunsan Oriental Hospital, Daejeon University, Republic of Korea, an institution that uses complementary therapies for cancer patients. METHODS: Five consecutive patients with CIPN were referred to the EWCC from March 20, 2010, to April 10, 2010. Patients with World Health Organization Chemotherapy-Induced Peripheral Neuropathy (WHO CIPN) grade 2 or more were treated with SBVP for 3 treatment sessions over a 1-week period. Measures of efficacy and safety. Validated Visual Analog System (VAS) pain scale, WHO CIPN grade, and Functional Assessment of Cancer Therapy-General (FACT-G) were compared before and after the 1-week course of treatment. To ensure the safety of SBVP, pretreatment skin response tests were given to patients to avoid any potential anaphylactic adverse effects. All patients were closely examined for any allergenic responses following each treatment session. RESULTS: One patient discontinued treatment after the first session, and 4 patients completed all treatment sessions. Using each patient as their own comparator, marked improvements of VAS, WHO CIPN grade, and physical section scores of FACT-G were seen in 3 patients. Most important, there were no related adverse side effects found. CONCLUSION: This safety results of the SBVP therapy merits further investigations in a larger size trial for it to develop into a potential intervention for managing CIPN symptoms. This study will be extended to a dose-response evaluation to further establish safety and response, prior to a randomized trial.
