Liquid Biopsy-based Precision Therapy in Patients with Advanced Solid Tumors: A Real-world Experience from a Community-based Oncology Practice.

BACKGROUND: Liquid biopsy testing offers a significant potential in selecting signal-matched therapies for advanced solid malignancies. The feasibility of liquid biopsy testing in a community-based oncology practice, and its actual impact on selecting signal-matched therapies, and subsequent survival effects have not previously been reported. PATIENTS AND METHODS: A retrospective chart review was conducted on adult patients with advanced solid cancer tested with a liquid-biopsy assay between December 2018 and 2019, in a community oncology practice. The impact of testing on treatment assignment and survival was assessed at 1-year follow-up. RESULTS: A total of 178 patients underwent testing. A positive test was reported in 140/178 patients (78.7%), of whom 75% had an actionable mutation. The actual overall signal-based matching rate was 17.8%. While 85.7% of patients with no actionable mutation had a signal-based clinical trial opportunity, only 10% were referred to a trial. Survival analysis of lung, breast, and colorectal cancer patients with actionable mutations who received any therapy (n = 66) revealed a survival advantage for target-matched (n = 22) compared to unmatched therapy (n = 44): patients who received matched therapy had significantly longer progression-free survival (PFS) (mPFS: 12 months; 95%CI, 10.6-13.4 vs. 5.0 months; 95%CI, 3.4-6.6; P = .029), with a tendency towards longer overall survival (OS) (mOS: 15 months; 95%CI, 13.5-16.5 vs. 13 months; 95%CI: 11.3-14.7; P = .087). CONCLUSIONS: Implementation of liquid biopsy testing is feasible in a US community practice and impacts therapeutic choices in patients with advanced malignancies. Receipt of liquid biopsy-generated signal-matched therapies conferred added survival benefits.

Neurological Complications of Acute and Chronic Otitis Media.

PURPOSE OF REVIEW: The aim of this study is to discuss the symptoms, diagnosis, and management of the neurologic complications of acute and chronic otitis media. RECENT FINDINGS: Antibiotic therapy has greatly reduced the frequency of complications of otitis media. However, it is of vital importance to remain aware of the possible development of neurologic complications. There is a trend toward less severe presenting symptoms including otorrhea, headache, nausea, and fever, with altered mental status and focal neurologic deficits presenting later. In order to reduce morbidity, early deployment of a multidisciplinary approach with prompt imaging and laboratory studies is imperative to guide appropriate management. Complications of acute and chronic otitis media may present with neurologic signs and symptoms. It is important to recognize the possible otitic origin of such complications to ensure proper management and to decrease overall morbidity and mortality.

A randomised controlled trial of an iPad-based application to complement early behavioural intervention in Autism Spectrum Disorder.

BACKGROUND: Technology-based interventions for Autism Spectrum Disorder (ASD) have proliferated, but few have been evaluated within the context of a randomised controlled trial (RCT). This RCT evaluated the efficacy of one technology-based early intervention programme (Therapy Outcomes By You; TOBY) in young children with ASD. METHODS: TOBY is an app-based learning curriculum designed for children and parents as a complement to early behavioural intervention. Eighty children (16 female) were recruited to this RCT within 12 months of receiving a diagnosis of ASD (M age = 3.38; SD = 0.69) and randomised to receive either treatment-as-usual (community-based intervention, n = 39) or the TOBY therapy (at least 20 min/day) plus treatment-as-usual (n = 41) for a period of 6 months. Outcomes were assessed at 3 and 6 months postbaseline. (Australian New Zealand Clinical Trials Registry: ACTRN12614000738628; www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=365463). RESULTS: Children in the TOBY intervention group averaged 19 min/day engaging with the app in the first 3 months, but only 2 min/day during the second 3 months. There was no group difference in scores on the primary outcome, the Autism Treatment Evaluation Checklist, at either the 3- or 6-month follow-up. However, significant improvements at the 6-month follow-up were observed in the TOBY intervention group relative to the treatment-as-usual group on three secondary outcomes: the Fine Motor and Visual Reception subscales of the Mullen Scale of Early Learning and the Total Words Understood scale of the MacArthur-Bates Communicative Development Index. Statistical trends towards improvement in the TOBY intervention group were observed on measures of adaptive function, although these decreased in magnitude from the 3- to 6-month follow-up. CONCLUSIONS: This study provides evidence that technology-based interventions may provide a relatively low-cost addition to existing therapist-delivered interventions for children with ASD. However, sustained use of the app over the full 6-month period was a challenge for most families.

Long-term follow-up of chemoimmunotherapy with rituximab, oxaliplatin, cytosine arabinoside, dexamethasone (ROAD) in patients with relapsed CD20+ B-cell non-Hodgkin lymphoma: Results of a study of the Mayo Clinic Cancer Center Research Consortium (MCCRC) MC0485 now known as academic and community cancer research united (ACCRU).

Patients with relapsed aggressive non-Hodgkin lymphoma (NHL) are often treated with platinum-based chemoimmunotherapy regimens in preparation for autologous stem cell transplant. We sought to reduce toxicity and maintain efficacy by using oxaliplatin with rituximab, cytarabine and dexamethasone (ROAD) in a phase II clinical trial in patients who had relapsed after one prior regimen. ROAD was delivered q21 days and consisted of rituximab 375 mg/m2 IV weekly x 4 doses (cycle 1 only); dexamethasone 40 mg PO/IV d2 - 5; oxaliplatin 130 mg/m2 IV day 2; cytarabine 2000 mg/m2 IV × two doses on days 2 to 3; and pegfilgrastim 6 mg SC on day 4. Forty-five eligible patients were accrued between 2006 and 2008. Patient characteristics were a median age of 69 years; 96% had received prior rituximab; 53% were within one year of diagnosis. The median number of cycles received was 2 (range, 1-6). Forty-four % received ROAD as an outpatient. The overall response rate was 71% with 27% (12/45) CR and 44% (20/45) PR. Forty-four % (20/45) of all patients and 69% (18/26) of patients whom responded after 2 cycles proceeded to transplant. Median overall survival was 26 mos (95% CI: 7.3 mos-not reached) and median progression-free survival was 11 mos (95% CI: 6-104 mos). There was no grade 3/4 nephrotoxicity; the rate of grade 3/4 neuropathy was 4%. Forty-two percent of all patients and 69% of patients transplanted remain alive at 5 years. ROAD represents an acceptable salvage therapeutic option for patients with relapsed aggressive NHL.

Nausea and disturbed sleep as predictors of cancer-related fatigue in breast cancer patients: a multicenter NCORP study.

PURPOSE: Cancer-related fatigue (CRF) is a prevalent and distressing side effect of cancer and its treatment that remains inadequately understood and poorly managed. A better understanding of the factors contributing to CRF could result in more effective strategies for the prevention and treatment of CRF. The objectives of this study were to examine the prevalence, severity, and potential predictors for the early onset of CRF after chemotherapy cycle 1 in breast cancer patients. METHODS: We report on a secondary data analysis of 548 female breast cancer patients from a phase III multi-center randomized controlled trial examining antiemetic efficacy. CRF was assessed by the Brief Fatigue Inventory at pre- and post-chemotherapy cycle 1 as well as by the four-day diary. RESULTS: The prevalence of clinically relevant post-CRF was 75%. Linear regression showed that pre-treatment CRF, greater nausea, disturbed sleep, and younger age were significant risk factors for post-CRF (adjusted R2 = 0.39; P < 0.0001). Path modeling showed that nausea severity influenced post-CRF both directly and indirectly by influencing disturbed sleep. Similarly, pre-treatment CRF influenced post-CRF directly as well as indirectly through both nausea severity and disturbed sleep. Pearson correlations showed that changes in CRF over time were significantly correlated with concurrent changes in nausea severity (r = 0.41; P < 0.0001) and in disturbed sleep (r = 0.20; P < 0.0001). CONCLUSION: This study showed a high prevalence (75%) of clinically relevant CRF in breast cancer patients following their initial chemotherapy, and that nausea severity, disturbed sleep, pre-treatment CRF, and age were significant predictors of symptom.

Phase II trial of R-CHOP plus bortezomib induction therapy followed by bortezomib maintenance for newly diagnosed mantle cell lymphoma: SWOG S0601.

Bortezomib is active in mantle cell lymphoma (MCL), with approval in upfront and relapsed settings. Given inevitable recurrence following induction chemoimmunotherapy, maintenance approaches are a rational strategy to improve clinical outcomes. We conducted a phase II study to evaluate the safety and efficacy of six cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) plus bortezomib (1.3 mg/m2 days 1 and 4 of 21 d cycles) followed by bortezomib maintenance (1.3 mg/m2 days 1, 4, 8, and 11 every 3 months for 2 years). Sixty-five eligible patients were enrolled. The treatment was well tolerated and toxicities were mainly haematological. The rate of grade ≥3 peripheral neuropathy was low (5%). With a median follow-up of 6.8 years, 2-year progression-free survival (PFS) was 62%, and 2-year overall survival (OS) was 85%. At 5 years, PFS was 28% and OS was 66%. MCL International Prognostic Index scores were significantly associated with 2-year PFS, but did not predict long-term (≥5-year) PFS. Baseline Ki-67 index was significantly associated with survival. Combination R-CHOP with bortezomib followed by maintenance bortezomib appears to improve outcomes compared historically with R-CHOP alone, with prolonged remissions in a subset of patients. These results suggest that inclusion of bortezomib with induction chemotherapy and/or maintenance is promising in MCL and warrants further exploration.

Randomised controlled trial of an iPad based early intervention for autism: TOBY playpad study protocol.

BACKGROUND: Evidence for early intensive behavioural interventions (EIBI) by therapists as an effective treatment for children with an Autism Spectrum Disorder (ASD) is growing. High-intensity and sustained delivery of quality EIBI is expensive. The TOBY (Therapy Outcomes by You) Playpad is an App-based platform delivering EIBI to facilitate learning for young children with ASD, while enabling parents to become co-therapists. Intervention targets include increasing joint attention, imitation and communication of children with ASD. The primary aim of the study presented in this protocol is to determine the effectiveness of the TOBY App in reducing ASD symptoms when used as a complement to conventional EIBI. The secondary aim is to examine parental attributes as a result of TOBY App use. METHODS AND DESIGN: Children aged less than 4;3 years diagnosed with ASD and parents will be recruited into this single-blind, randomised controlled trial using a pragmatic approach. Eligible participants will be randomised to the treatment group 'TOBY therapy + therapy as usual' or, the control group 'therapy as usual' for six months. The treatment will be provided by the TOBY App and parent where a combination of learning environments such as on-iPad child only (solo), partner (with parent) and off-iPad - Natural Environment (with parent) Tasks will be implemented. Parents in the treatment group will participate in a TOBY training workshop. Treatment fidelity will be monitored via an App-based reporting system and parent diaries. The primary outcome measure is the Autism Treatment Evaluation Checklist. The secondary outcome measures involve diagnostics, functional and developmental assessments, including parent questionnaires at baseline (T0), three months (T1) and six months (T2). DISCUSSION: This trial will determine the effectiveness of the TOBY App as a therapeutic complement to other early interventions children with ASD receive. The trial will also determine the feasibility of a parent delivered early intervention using the iPad as an educational platform, and assess the impact of the TOBY App on parents' self-efficacy and empowerment in an effort to reduce children's ASD symptoms. The outcomes of this trial may have EIBI services implications for newly diagnosed children with ASD and parents.

A randomized comparison of once weekly epoetin alfa to extended schedule epoetin or darbepoetin in chemotherapy-associated anemia.

Erythropoiesis-stimulating agents (ESAs) epoetin alfa (EA) and darbepoetin alfa (DA) increase hemoglobin (Hb) levels and reduce red blood cell (RBC) transfusion requirements in patients with cancer chemotherapy-associated anemia (CAA). Extended-interval ESA dosing (administration less than once weekly) is common with DA, but previous studies suggested that EA might also be administered less often than weekly. In this multicenter prospective trial, 239 CAA patients with Hb <10.5 g/dL were randomized to receive EA 40,000 U subcutaneously once weekly ("40K" arm), EA 80,000 U every 3 weeks ("80K"), EA 120,000 U every 3 weeks ("120K" arm), or DA 500 mcg every 3 weeks ("DA"), for 15 weeks. The primary endpoint was the proportion of patients achieving Hb ≥ 11.5 g/dL or increment of Hb > 2.0 g/dL from baseline without transfusion. Secondary endpoints included transfusion requirements, adverse events (AEs), and patient-reported outcomes (PROs). There were no significant differences between treatment arms in the proportion of patients achieving Hb response (68.9% for 40K, 61.7% for 80K, 65.5% for 120K, and 66.7% for DA; P > 0.41 for all comparisons) or requiring RBC transfusion, but the median Hb increment from baseline was higher in the 40K and DA arms compared to the two extended dosing EA arms, and Hb response was achieved soonest in the weekly EA arm. There were no differences in PROs or AEs. The FDA-approved schedules tested-weekly EA 40,000 U, and every 3 week DA 500 mcg-are reasonable standards for CAA therapy.

A Phase III study of radiation therapy (RT) and O6-benzylguanine + BCNU versus RT and BCNU alone and methylation status in newly diagnosed glioblastoma and gliosarcoma: Southwest Oncology Group (SWOG) study S0001.

AIMS: To determine the efficacy of methylguanine methyltransferase (MGMT) depletion + BCNU [1,3-bis(2-chloroethyl)-1- nitrosourea: carmustine] therapy and the impact of methylation status in adults with glioblastoma multiforme (GBM) and gliosarcoma. METHODS: Methylation analysis was performed on GBM patients with adequate tissue samples. Patients with newly diagnosed GBM or gliosarcoma were eligible for this Phase III open-label clinical trial. At registration, patients were randomized to Arm 1, which consisted of therapy with O(6)-benzylguanine (O(6)-BG) + BCNU 40 mg/m(2) (reduced dose) + radiation therapy (RT) (O6BG + BCNU arm), or Arm 2, which consisted of therapy with BCNU 200 mg/m(2) + RT (BCNU arm). RESULTS: A total of 183 patients with newly diagnosed GBM or gliosarcoma from 42 U.S. institutions were enrolled in this study. Of these, 90 eligible patients received O(6)-BG + BCNU + RT and 89 received BCNU + RT. The trial was halted at the first interim analysis in accordance with the guidelines for stopping the study due to futility (<40 % improvement among patients on the O6BG + BCNU arm). Following adjustment for stratification factors, there was no significant difference in overall survival (OS) or progression-free survival (PFS) between the two groups (one sided p = 0.94 and p = 0.88, respectively). Median OS was 11 [95 % confidence interval (CI) 8-13] months for patients in the O6BG + BCNU arm and 10 (95 % CI 8-12) months for those in the BCNU arm. PFS was 4 months for patients in each arm. Adverse events were reported in both arms, with significantly more grade 4 and 5 events in the experimental arm. CONCLUSIONS: The addition of O(6)-BG to the standard regimen of radiation and BCNU for the treatment patients with newly diagnosed GBM and gliosarcoma did not provide added benefit and in fact caused additional toxicity.

Ultrasmall, elementary and highly translational nanoparticle X-ray contrast media from amphiphilic iodinated statistical copolymers.

To expand the single-dose duration over which noninvasive clinical and preclinical cancer imaging can be conducted with high sensitivity, and well-defined spatial and temporal resolutions, a facile strategy to prepare ultrasmall nanoparticulate X-ray contrast media (nano-XRCM) as dual-modality imaging agents for positron emission tomography (PET) and computed tomography (CT) has been established. Synthesized from controlled copolymerization of triiodobenzoyl ethyl acrylate and oligo(ethylene oxide) acrylate monomers, the amphiphilic statistical iodocopolymers (ICPs) could directly dissolve in water to afford thermodynamically stable solutions with high aqueous iodine concentrations (>140 mg iodine/mL water) and comparable viscosities to conventional small molecule XRCM. The formation of ultrasmall iodinated nanoparticles with hydrodynamic diameters of ca. 10 nm in water was confirmed by dynamic and static light scattering techniques. In a breast cancer mouse model, in vivo biodistribution studies revealed that the 64Cu-chelator-functionalized iodinated nano-XRCM exhibited extended blood residency and higher tumor accumulation compared to typical small molecule imaging agents. PET/CT imaging of tumor over 3 days showed good correlation between PET and CT signals, while CT imaging allowed continuous observation of tumor retention even after 10 days post-injection, enabling longitudinal monitoring of tumor retention for imaging or potentially therapeutic effect after a single administration of nano-XRCM.

Clinical Utility of Genomic Recurrence Risk Stratification in Early, Hormone-Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative Breast Cancer: Real-World Experience.

BACKGROUND: RNA-based genomic risk assessment estimates chemotherapy benefit in patients with hormone-receptor positive (HR+)/Human Epidermal Growth Factor 2-negative (ERBB2-) breast cancer (BC). It is virtually used in all patients with early HR+/ERBB2- BC regardless of clinical recurrence risk. PATIENTS AND METHODS: We conducted a retrospective chart review of adult patients with early-stage (T1-3; N0; M0) HR+/ERBB2- BC who underwent genomic testing using the Oncotype DX (Exact Sciences) 21-genes assay. Clinicopathologic features were collected to assess the clinical recurrence risk, in terms of clinical risk score (CRS) and using a composite risk score of distant recurrence Regan Risk Score (RRS). CRS and RRS were compared to the genomic risk of recurrence (GRS). RESULTS: Between January 2015 and December 2020, 517 patients with early-stage disease underwent genomic testing, and clinical data was available for 501 of them. There was statistically significant concordance between the 3 prognostication methods (P < 0.01). Within patients with low CRS (n = 349), 9.17% had a high GRS, compared to 8.93% in patients with low RRS (n = 280). In patients with grade 1 histology (n = 130), 3.85% had a high GRS and 68.46% had tumors > 1 cm, of whom only 4.49% had a high GRS. Tumor size > 1cm did not associate with a high GRS. CONCLUSION: Genomic testing for patients with grade 1 tumors may be safely omitted, irrespective of size. Our finds call for a better understanding of the need for routine genomic testing in patients with low grade/low clinical risk of recurrence.

Lenalidomide and high-dose dexamethasone compared with dexamethasone as initial therapy for multiple myeloma: a randomized Southwest Oncology Group trial (S0232).

The Southwest Oncology Group conducted a randomized trial comparing lenalidomide (LEN) plus dexamethasone (DEX; n = 97) to placebo (PLC) plus DEX (n = 95) in newly diagnosed myeloma. Three 35-day induction cycles applied DEX 40 mg/day on days 1 to 4, 9 to 12, and 17 to 20 together with LEN 25 mg/day for 28 days or PLC. Monthly maintenance used DEX 40 mg/day on days 1 to 4 and 15 to 18 along with LEN 25 mg/day for 21 days or PLC. Crossover from PLC-DEX to LEN-DEX was encouraged on progression. One-year progression-free survival, overall response rate, and very good partial response rate were superior with LEN-DEX (78% vs 52%, P = .002; 78% vs 48%, P < .001; 63% vs 16%, P < .001), whereas 1-year overall survival was similar (94% vs 88%; P = .25). Toxicities were more pronounced with LEN-DEX (neutropenia grade 3 or 4: 21% vs 5%, P < .001; thromboembolic events despite aspirin prophylaxis: 23.5% [initial LEN-DEX or crossover] vs 5%; P < .001). This trial was registered at www.clinicaltrials.gov as #NCT00064038.

A pilot study of long-acting octreotide for symptomatic malignant ascites.

BACKGROUND: Effective, non-invasive, palliative strategies for symptomatic malignant ascites are unavailable. This trial explored whether octreotide, an inhibitor of vascular endothelial growth factor, a putative mediator of ascites, prolongs the interval to next paracentesis. METHODS: After a baseline paracentesis and a test of short-acting agent, patients with symptomatic ascites were randomly assigned to long-acting octreotide (Sandostatin LAR®) depot 30 mg intramuscularly every month versus 0.9% sodium chloride administered similarly. Patients were then monitored for recurrent, symptomatic ascites. RESULTS: Thirty-three patients were enrolled: 16 assigned to the octreotide and 17 to the control arm. The median time to next paracentesis was 28 and 14 days in the octreotide and placebo arm, respectively (p = 0.17). After adjustment for extracted ascites volume and abdominal girth change, no statistically significant difference between the groups was observed (hazard ratio = 0.52, with a 95% confidence interval of 0.21-1.28; p = 0.15, per Cox model). Octreotide-treated patients described less of abdominal bloating (p = 0.01), abdominal discomfort (p = 0.02), and shortness of breath (p = 0.007) at one month, although other quality of life symptoms were comparable between the arms. Long-acting octreotide was reasonably well tolerated. CONCLUSION: As prescribed in this trial, octreotide did not seem effective in prolonging the time to next paracentesis, although improvements in symptoms suggest that vascular endothelial growth factor inhibition merits further investigation.

The Natural History of Small Vestibular Schwannomas.

Objective The incidence of vestibular schwannomas is increasing, and the average tumor size at diagnosis is decreasing. Therefore, understanding the specific growth pattern of small vestibular schwannomas is becoming increasingly important to guide clinical management. The objectives of this study were to evaluate the growth patterns of very small intracanalicular vestibular schwannomas measuring ≤ 4 mm in linear diameter and to assess the likelihood of these lesions ever requiring treatment.  Methods A retrospective review was performed. A search of all MRI brain and internal auditory canal studies suggestive of a vestibular schwannoma from 1995 to 2019 was performed at our institution. This resulted in 372 cases, which were then evaluated for the presence of a vestibular schwannoma measuring ≤ 4 mm. All patients had to have at least one follow-up MRI to be included. Images were reviewed by a neuroradiologist. Results Eight ≤ 4 mm vestibular schwannomas were found that met all search criteria. The distribution of tumor sizes was as follows: three 2 mm, one 3 mm and four 4 mm. None of the ≤ 4 mm vestibular schwannomas identified demonstrated any significant growth in the linear dimension defined as greater than 2 mm of growth over observation times of 1-13 years (mean 6.3 years). None of the lesions ever required a treatment intervention per available medical records. Conclusion None of the ≤ 4 mm intracanalicular vestibular schwannomas identified in this study grew significantly or required treatment. Overall, the findings in this study suggest that vestibular schwannomas measuring ≤ 4 mm are unlikely to grow and ever require treatment.

Phase II trial of lapatinib and topotecan (LapTop) in patients with platinum-refractory/resistant ovarian and primary peritoneal carcinoma.

OBJECTIVE: Resistance to chemotherapy is a major challenge in the treatment of ovarian/peritoneal cancer. One purported mechanism of topotecan resistance is the breast cancer resistance protein (BCRP) and P-glycoprotein (Pgp). We designed a phase II clinical trial evaluating the efficacy and adverse event profile of concomitant topotecan and lapatinib, a small molecule pan-erbB inhibitor that can block BCRP/Pgp efflux of topotecan. METHODS: Patients with platinum-refractory or resistant epithelial ovarian/peritoneal cancer were treated with topotecan 3.2 mg/m² IV on Day 1, 8 and 15 and lapatinib 1250 mg PO daily, continuously in 28 day cycles. The primary endpoint was response rate. For correlative studies, archived tissue was assessed for expression of EGFR, HER2, HIF-1α, CD31, and BCRP. RESULTS: Eighteen patients were enrolled and treated. Four experienced evidence of clinical benefit: one partial response and three with stable disease. Using a two-stage Simon design, the trial was stopped after the first stage due to insufficient activity. Grades 3+ and 4+ adverse events (AE) were experienced in 14 and 4 patients, respectively. The most common grade 3/4 AE were neutropenia (56%), thrombocytopenia (28%), and diarrhea (22%). CONCLUSIONS: The combination of lapatinib plus topotecan for the treatment of platinum refractory/resistant epithelial ovarian cancer lacks sufficient activity to warrant further investigation. In particular, hematologic adverse events were substantial. Expression of correlative study markers did not reveal patterns of predicted benefit or toxicity. Disruption of erbB signaling and BCRP/Pgp efflux with lapatinib was insufficient for overcoming topotecan resistance, suggesting alternative mechanisms of resistance are involved.

A phase III randomized, double-blind, placebo-controlled study of pilocarpine for vaginal dryness: North Central Cancer Treatment group study N04CA.

Vaginal dryness is a common problem for which effective and safe nonestrogenic treatments are needed. Based on preliminary promising data that pilocarpine attenuated vaginal dryness, the current trial was conducted. A double-blind, placebo-controlled, randomized trial design was used to compare pilocarpine, at target doses of 5 mg twice daily and 5 mg four times daily, with a placebo. Vaginal dryness was recorded by patient-completed questionnaires at baseline and weekly for 6 weeks after study initiation. The primary endpoint for this study was the area under the curve summary statistic composed of the longitudinal responses obtained at baseline and through the 6 weeks of treatment to a numerical analogue scale asking patients to rate their perceived amount of vaginal dryness. The primary analysis was carried out by a single t test using a two-side alternative to compare the collective pilocarpine treatment arms with the collective placebo arms. A total of 201 patients enrolled in this trial. The primary analysis, comparing vaginal dryness symptoms in the collective pilocarpine arms against the placebo arm, did not reveal any benefit for the pilocarpine treatment. This finding was confirmed by other secondary analyses. Toxicity evaluation revealed more nausea, sweating, rigors, and urinary frequency with the pilocarpine arms compared with the placebo arm.

The use of Valeriana officinalis (Valerian) in improving sleep in patients who are undergoing treatment for cancer: a phase III randomized, placebo-controlled, double-blind study (NCCTG Trial, N01C5).

Sleep disorders are a substantial problem for cancer survivors, with prevalence estimates ranging from 23% to 61%. Although numerous prescription hypnotics are available, few are approved for long-term use or have demonstrated benefit in this circumstance. Hypnotics may have unwanted side effects and are costly, and cancer survivors often wish to avoid prescription drugs. New options with limited side effects are needed. The purpose of this trial was to evaluate the efficacy of a Valerian officinalis supplement for sleep in people with cancer who were undergoing cancer treatment. Participants were randomized to receive 450 mg of valerian-or placebo orally 1 hour before bedtime for 8 weeks. The primary end point was area under the curve (AUC) of the overall Pittsburgh Sleep Quality Index (PSQI). Secondary outcomes included the Functional Outcomes of Sleep Questionnaire, the Brief Fatigue Inventory (BFI), and the Profile of Mood States (POMS). Toxicity was evaluated with both self-reported numeric analogue scale questions and the Common Terminology Criteria for Adverse Events (CTCAE), version 3.0. Questionnaires were completed at baseline and at 4 and 8 weeks. A total of 227 patients were randomized into this study between March 19, 2004, and March 9, 2007, with 119 being evaluable for the primary end point. The AUC over the 8 weeks for valerian was 51.4 (SD = 16), while that for placebo was 49.7 (SD = 15), with a P value of 0.6957. A supplemental, exploratory analysis revealed that several fatigue end points, as measured by the BFI and POMS, were significantly better for those taking valerian over placebo. Participants also reported less trouble with sleep and less drowsiness on valerian than placebo. There were no significant differences in toxicities as measured by self-report or the CTCAE except for mild alkaline phosphatase increases, which were slightly more common in the placebo group. This study failed to provide data to support the hypothesis that valerian, 450 mg, at bedtime could improve sleep as measured by the PSQI. However, exploratory analyses revealed improvement in some secondary outcomes, such as fatigue. Further research with valerian exploring physiologic effects in oncology symptom management may be warranted.

Racial disparities in traumatic stress in prostate cancer patients: secondary analysis of a National URCC CCOP Study of 317 men.

INTRODUCTION: African American men have the highest rates of prostate cancer of any racial group, but very little is known about the psychological functioning of African American men in response to prostate cancer diagnosis and treatment. PURPOSE: In this secondary analysis of a national trial testing a psychological intervention for prostate cancer patients, we report on the traumatic stress symptoms of African American and non-African American men. METHODS: This analysis includes 317 men (African American: n = 30, 9%; non-African American: n = 287, 91%) who were enrolled in the intervention trial, which included 12 weeks of group psychotherapy and 24 months of follow-up. Using mixed model analysis, total score on the Impact of Events Scale (IES) and its Intrusion and Avoidance subscales were examined to determine mean differences in traumatic stress across all time points (0, 3, 6, 12, 18, and 24 months). In an additional analysis, relevant psychosocial, demographic, and clinical variables were added to the model. RESULTS: Results showed significantly higher levels of traumatic stress for African American men compared to non-African American men in all models independently of the intervention arm, demographics, and relevant clinical variables. African Americans also had a consistently higher prevalence of clinically significant traumatic stress symptoms (defined as IES total score ≥ 27). These elevations remained across all time points over 24 months. CONCLUSIONS: This is the first study to show a racial disparity in traumatic stress specifically as an aspect of overall psychological adjustment to prostate cancer. Recommendations are made for appropriate assessment, referral, and treatment of psychological distress in this vulnerable population.

Colostrum avoidance, prelacteal feeding and late breast-feeding initiation in rural Northern Ethiopia.

OBJECTIVE: To identify specific cultural and behavioural factors that might be influenced to increase colostrum feeding in a rural village in Northern Ethiopia to improve infant health. DESIGN: Background interviews were conducted with six community health workers and two traditional birth attendants. A semi-structured tape-recorded interview was conducted with twenty mothers, most with children under the age of 5 years. Variables were: parental age and education; mother's ethnicity; number of live births and children's age; breast-feeding from birth through to weaning; availability and use of formula; and descriptions of colostrum v. other stages of breast milk. Participant interviews were conducted in Amharic and translated into English. SETTING: Kossoye, a rural Amhara village with high prevalence rates of stunting: inappropriate neonatal feeding is thought to be a factor. SUBJECTS: Women (20-60 years of age) reporting at least one live birth (range: 1-8, mean: ∼4). RESULTS: Colostrum (inger) and breast milk (yetut wotet) were seen as different substances. Colostrum was said to cause abdominal problems, but discarding a portion was sufficient to mitigate this effect. Almost all (nineteen of twenty) women breast-fed and twelve (63 %) reported ritual prelacteal feeding. A majority (fifteen of nineteen, 79 %) reported discarding colostrum and breast-feeding within 24 h of birth. Prelacteal feeding emerged as an additional factor to be targeted through educational intervention. CONCLUSIONS: To maximize neonatal health and growth, we recommend culturally tailored education delivered by community health advocates and traditional health practitioners that promotes immediate colostrum feeding and discourages prelacteal feeding.

Cochlear Implantation in Vestibular Schwannoma: A Systematic Literature Review.

Objective Ipsilateral cochlear implantation (CI) in vestibular schwannoma (VS) has been an emerging trend over the last two decades. We conducted the first systematic review of hearing outcomes comparing neurofibromatosis 2 (NF2) and sporadic VS undergoing CI. A comparison of the two populations and predictor of outcome was assessed. This is an update to a previously presented study. Data Sources Systemic data searches were performed in PubMed NCBI and Scopus by an academic librarian. No restrictions based on the year of publication were used. Study Selection Studies were selected if patients had a diagnosis of NF2 and a CI placed in the affected side with reports of hearing outcome. Two independent reviewers screened each abstract and full-text article. Data Extraction Studies were extracted at the patient level, and the assessment of quality and bias was evaluated according to the National Institutes of Health Quality Assessment Tool. Main Outcome Measures Outcome predictors were determined by using the chi-square test and Student's t -test. Results Overall, most CI recipients functioned in the high-to-intermediate performer category for both sporadic and NF2-related VS. Median AzBio (Arizona Biomedical Institute Sentence Test) was 72% (interquartile range [IQR]: 50) in NF2 patients and 70% (IQR: 7.25) in sporadic patients. Larger tumor size predicted a poorer final audiometric outcome. Conclusions Categorization of hearing outcome into superior performance and inferior performance based on sentence recognition revealed a generally good hearing outcome regardless of treatment or patient population. Select patients with sporadic and NF2 VS may benefit from CI.
