RESUMEN

BACKGROUND: Female cancer survivors often experience estrogen-deprivation symptoms, which may lead to decreases in sexual desire, vulvovaginal health (lubrication, dryness, discomfort), and sexual satisfaction. Interventions are needed to address these concerns. AIM: The objective of this secondary analysis was to determine if women with higher (better) scores on the Female Sexual Function Index (FSFI) lubrication and pain subscales reported higher desire scores based on treatment with bupropion vs placebo. METHODS: Participants were part of NRG Oncology's NRG-CC004 (NCT03180294), a randomized placebo-controlled clinical trial evaluating bupropion (150 vs 300 mg) to improve sexual desire in survivors of breast or gynecologic cancer. All participants with baseline data from the FSFI lubrication, pain, and desire subscales with 5- and/or 9-week data were analyzed. The FSFI subscale scores were correlated using Spearman correlation coefficients. Logistic regression was used to determine associations between FSFI desire and other FSFI subscales while accounting for treatment arm and other covariates. OUTCOMES: The primary outcome of NRG Oncology's NRG-CC004 (NCT03180294) randomized phase II dose-finding trial was change from baseline to 9 weeks on the FSFI desire subscale score. Similar to the parent study, the primary outcome for this ancillary data study was the FSFI desire subscale score at 5 and 9 weeks. RESULTS: Overall, 230 participants completed the FSFI at baseline and 189 at 9 weeks. The strongest correlations were between lubrication and pain at baseline (all participants, rho = 0.77; bupropion arms, rho = 0.82), week 5 (all participants, rho = 0.71; bupropion arms, rho = 0.68), and week 9 (all participants, rho = 0.75; bupropion arms, rho = 0.78), and the weakest correlations were between desire and pain. In patients in the treatment arms there were no interactions between lubrication or pain.The impact of various covariates on the FSFI score for desire at 9 weeks demonstrated that participants of non-White race (odds ratio [OR], 0.42; 95% CI, 0.21-0.81; P = .010), with a high lubrication score (OR, 0.36; 95% CI, 0.21-0.61; P = .0002), with a high pain score (less pain) (OR, 0.50; 95% CI, 0.29-0.87; P = .014), or with prior pelvic surgery (OR, 0.38; 95% CI, 0.23-0.63; P = .0002) had lower odds of having low desire. CLINICAL IMPLICATIONS: Acute estrogen-deprivation symptoms should be addressed prior to sexual desire intervention. STRENGTHS AND LIMITATIONS: This secondary analysis was not powered to examine all variables. CONCLUSION: Lubrication and pain were predictors of low desire. Therefore, vulvovaginal atrophy and associated genitourinary symptoms of menopause such as vaginal dryness and dyspareunia should be addressed prior to or in parallel with interventions for sexual desire.

RESUMEN

The purpose of this study was to evaluate the feasibility of delivering a supervised physical activity program plus standard exercise counseling (PA + EC) versus a supervised physical activity plus motivationally-enhanced behavioral counseling (PA + BC) in prostate cancer survivors. Secondary outcomes included objectively assessed PA, quality of life, body composition, cardiorespiratory fitness, cognitive functioning, and physical function. Twenty-six prostate cancer survivors were randomized to a 12-week supervised PA program plus standard exercise counseling or a 12-week supervised PA plus behavioral counseling based on the Multi-Process Action Control framework. Feasibility was determined through enrolment rate, measurement completion rate, loss-to-follow-up, adherence to the intervention, adverse events, and program evaluation items assessing burden and satisfaction. Of the 26 prostate cancer survivors enrolled (Mage = 65.6 ± 6.8), 96% completed the intervention. Measurement completion rates for the study measures were 88.5%. Adherence to the supervised PA sessions was 92% (completed 11/12 supervised PA sessions) and 100% (completed 12/12 supervised PA sessions) in the PA + EC and PA + BC group, respectively. Adherence to the home-based PA sessions was 70% (completed 7/10 home-based sessions) and 90% (completed 9/10 home-based sessions) in the PA + EC and PA + BC group, respectively. Overall, prostate cancer survivors were highly satisfied with the intervention components and found it rewarding, useful for research helping others, and useful for them personally. The patterns in the secondary outcomes were consistent with a positive impact of the intervention, favoring the PA + BC group. Preliminary evidence suggests that adding behavioral counseling to supervised PA in prostate cancer survivors may be feasible and result in better adherence to PA compared to exercise counseling alone, although additional refinement is needed. A combination of supervised and home-based PA may be feasible for behavior change in the self-management of prostate cancer. The study is registered with http://ClinicalTrials.gov (ID NCT03191968).

RESUMEN

BACKGROUND: Many breast cancer survivors (BCS) report deficits in cognitive function. Physical activity (PA) has been associated with better processing speed and memory in healthy adults and thus may be a useful method for improving cognition in BCS. The purpose of this study was to examine the effects of an acute bout of PA on processing speed and spatial working memory in a sample of BCS. METHODS: Using a repeated measures, crossover design, BCS [N = 27; Mage (SD) = 49.11(8.05)] completed two sessions in counterbalanced order: 30 min of moderate-intensity treadmill walking and 30 min of seated rest. Women completed cognitive tasks immediately before and after each session. RESULTS: Within-subjects repeated measures analyses of variance revealed a significant time by session effect for processing speed reaction time [F (1,25) = 5.02, p = .03, η2 = 0.17]. This interaction was driven by significantly reduced reaction time (e.g., faster response) post-exercise and no change post-rest. Further between-subjects analyses indicated a significant time by session by moderate to vigorous physical activity (MVPA) split [F (1,25) = 5.23, p = .03, η2 = 0.17], such that women who engaged in ≥45 min of average daily MVPA reduced their reaction time post-exercise (p = .01) and increased RT post-rest (p = .06). Time by session effects for spatial working memory 3-item accuracy and 4-item reaction time trended towards significance, p = 0.08 and p = 0.10, respectively, again driven by better performance post-exercise. CONCLUSIONS: The moderate effect of acute exercise on domains of memory and processing speed in BCS is encouraging. Cancer-related cognitive impairment remains largely misunderstood; however, the results from the present study offer preliminary evidence for the positive relationship between acute exercise and cognition in BCS.

RESUMEN

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.

RESUMEN

BACKGROUND: Treatment of breast cancer with aromatase inhibitors is associated with damage to bones. NCIC CTG MA.27 was an open-label, phase 3, randomised controlled trial in which women with breast cancer were assigned to one of two adjuvant oral aromatase inhibitors-exemestane or anastrozole. We postulated that exemestane-a mildly androgenic steroid-might have a less detrimental effect on bone than non-steroidal anastrozole. In this companion study to MA.27, we compared changes in bone mineral density (BMD) in the lumbar spine and total hip between patients treated with exemestane and patients treated with anastrozole. METHODS: In MA.27, postmenopausal women with early stage hormone (oestrogen) receptor-positive invasive breast cancer were randomly assigned to exemestane 25 mg versus anastrozole 1 mg, daily. MA.27B recruited two groups of women from MA.27: those with BMD T-scores of -2·0 or more (up to 2 SDs below sex-matched, young adult mean) and those with at least one T-score (hip or spine) less than -2·0. Both groups received vitamin D and calcium; those with baseline T-scores of less than -2·0 also received bisphosphonates. The primary endpoints were percent change of BMD at 2 years in lumbar spine and total hip for both groups. We analysed patients according to which aromatase inhibitor and T-score groups they were allocated to but BMD assessments ceased if patients deviated from protocol. This study is registered with ClinicalTrials.gov, NCT00354302. FINDINGS: Between April 24, 2006, and May 30, 2008, 300 patients with baseline T-scores of -2·0 or more were accrued (147 allocated exemestane, 153 anastrozole); and 197 patients with baseline T-scores of less than -2·0 (101 exemestane, 96 anastrozole). For patients with T-scores greater than -2·0 at baseline, mean change of bone mineral density in the spine at 2 years did not differ significantly between patients taking exemestane and patients taking anastrozole (-0·92%, 95% CI -2·35 to 0·50 vs -2·39%, 95% CI -3·77 to -1·01; p=0·08). Respective mean loss in the hip was -1·93% (95% CI -2·93 to -0·93) versus -2·71% (95% CI -4·32 to -1·11; p=0·10). Likewise for those who started with T-scores of less than -2·0, mean change of spine bone mineral density at 2 years did not differ significantly between the exemestane and anastrozole treatment groups (2·11%, 95% CI -0·84 to 5·06 vs 3·72%, 95% CI 1·54 to 5·89; p=0·26), nor did hip bone mineral density (2·09%, 95% CI -1·45 to 5·63 vs 0·0%, 95% CI -3·67 to 3·66; p=0·28). Patients with baseline T-score of -2·0 or more taking exemestane had two fragility fractures and two other fractures, those taking anastrozole had three fragility fractures and five other fractures. For patients who had baseline T-scores of less than -2·0 taking exemestane, one had a fragility fracture and four had other fractures, whereas those taking anastrozole had five fragility fractures and one other fracture. INTERPRETATION: Our results demonstrate that adjuvant treatment with aromatase inhibitors can be considered for breast cancer patients who have T-scores less than -2·0.

RESUMEN

PURPOSE: To test efficacy of donepezil, a cognitive enhancer, to improve memory in breast cancer survivors who report cancer-related cognitive impairment 1-5 years postchemotherapy. PATIENTS AND METHODS: Adult female BCS exposed to ≥4 cycles of adjuvant chemotherapy 1-5 years before enrollment who reported cancer-related cognitive impairment were eligible. Participants, enrolled at sites affiliated with the Wake Forest NCI Community Oncology Research Program (NCORP) Research Base, were randomly assigned to receive 5 mg of donepezil once daily for 6 weeks titrated to 10 mg once daily for 18 weeks or placebo. Cognition and self-report cognitive functioning was assessed at baseline, 12, 24 (end of intervention), and 36 (washout) weeks postrandomization. Mixed-effects repeated measures analysis of covariance models were used to assess treatment differences in immediate recall (primary outcome) on the Hopkins Verbal Learning Test-Revised (HVLT-R) and other cognitive domains (secondary outcomes) with covariates of treatment, time, time by treatment interaction, baseline outcome level, age stratification, and an unstructured covariance matrix to account for within participant correlation over time. RESULTS: Two hundred seventy-six BCS from 87 NCORP practices (mean age, 57.1, standard deviation [SD], 10.5) who were at a mean of 29.6 months (SD, 14.2) postchemotherapy were randomly assigned to donepezil (n = 140) or placebo (n = 136). At 24 weeks, treatment groups did not differ on HVLT-R scores (donepezil mean = 25.98, placebo = 26.50, P = .32). There were no statistically significant differences between treatments at 12, 24, or 36 weeks for attention, executive function, verbal fluency, processing speed, or self-reported cognitive functioning. Endocrine therapy and menopausal status did not affect results. CONCLUSION: BCS 1-5 years after completing chemotherapy with documented memory problems, randomly assigned to 24 weeks of 5-10 mg of donepezil once daily, did not perform differently at the end of treatment on tests of memory, other cognitive functions, or subjective functioning than those randomly assigned to placebo.

RESUMEN

The 14-3-3ζ gene, on 8q22, is often amplified in breast cancer and encodes a survival factor that interacts with and stabilizes many key signaling proteins. We examined the relationship between the expression of 14-3-3ζ, estrogen receptor α (ERα), and other parameters ( tumor size, grade, nodal status, progesterone receptor, HER2, EGFR, and p53) in matched primary and recurrence tumor tissue and how these factors impact time to recurrence, properties of the recurred tumors, and site of metastasis. In this cohort of over 100 patients, median time to recurrence was 3 years (range 1-17 years). Our analyses of primary tumor microarray cores revealed that 14-3-3ζ status was significantly correlated with tumor grade, size, and ERα. Women with 14-3-3ζ-positive and ERα-negative tumors had the earliest time to recurrence (median 1 yr, p < 0.001, hazard ratio 2.89), while median time to recurrence was 7 years for 14-3-3ζ-negative and ER-positive tumors. Of recurred tumors, 70-75 % were positive for 14-3-3ζ, up from the 45 % positivity of primary tumors. High expression of 14-3-3ζ also correlated with site of recurrence and showed a propensity for distant metastases to lung and chest wall. Multifactor correlation regression analysis revealed 14-3-3ζ to be a non-redundant, independent variable that adds clinical strength in predicting risk for early recurrence in ER-positive and -negative breast cancers, providing information beyond that of all other clinical pathological features examined. Thus, high expression of 14-3-3ζ in the primary tumor was significantly associated with earlier time to recurrence and with distant metastasis. Furthermore, even when the primary breast cancers were negative-low for 14-3-3ζ, the majority acquired increased expression in the recurrence. The findings underscore the detrimental role played by 14-3-3ζ in tumor aggressiveness and suggest that reducing its expression or interfering with its actions might substantially improve the clinical outcome for breast cancer patients.

RESUMEN

PURPOSE: Patients undergoing treatment for cancer often report problems with their cognitive function, which is an essential component of health-related quality of life. Pursuant to this, a two-arm randomized, placebo-controlled, double-blind, phase III clinical trial was conducted to evaluate Ginkgo biloba (EGB 761) for the prevention of chemotherapy-related cognitive dysfunction in patients with breast cancer. METHODS: Previously chemotherapy naïve women about to receive adjuvant chemotherapy for breast cancer were randomized to receive 60 mg of EGB 761 or a matching placebo twice daily. The study agent was to begin before their second cycle of chemotherapy and to be taken throughout chemotherapy and 1 month beyond completion. The primary measure for cognitive function was the High Sensitivity Cognitive Screen (HSCS), with a secondary measure being the Trail Making Tests (TMT) A and B. Subjective assessment of cognitive function was evaluated by the cognitive subscale of the Perceived Health Scale (PHS) and the Profile of Mood States (POMS). Data were collected at baseline and at intervals throughout and after chemotherapy, up to 24 months after completion of adjuvant treatment. The primary statistical analysis included normalized area under the curve (AUC) comparisons of the HSCS, between the arms. Secondary analyses included evaluation of the other measures of cognition as well as correlational analyses between self-report and cognitive testing. RESULTS: One hundred and sixty-six women provided evaluable data. There were no significant differences in AUC up to 12 months on the HSCS between arms at the end of chemotherapy or at any other time point after adjuvant treatment. There were also no significant differences in TMT A or B at any data point. Perceived cognitive functions, as measured by the PHS and confusion/bewilderment subscale of the POMS, were not different between arms at the end of chemotherapy. There was also little correlation between self-reported cognition and cognitive testing. No differences were observed in toxicities per Common Terminology Criteria for Adverse Events (CTCAE) assessment between Ginkgo biloba and placebo throughout the study; however, after chemotherapy, the placebo group reported worse nausea (p = .05). CONCLUSION: This study did not provide any support for the notion that Ginkgo biloba, at a dose of 60 mg twice a day, can help prevent cognitive changes from chemotherapy. These analyses do provide data to further support the low associations between patients' self-report of cognition and cognitive performance, based on more formal testing.

RESUMEN

PURPOSE: Because of the negative impact of cancer treatment on female sexual function, effective treatments are warranted. The purpose of this multisite study was to evaluate the ability of two dose levels of extended-release bupropion, a dopaminergic agent, to improve sexual desire more than placebo at 9 weeks, measured by the desire subscale of the Female Sexual Function Index (FSFI), and to evaluate associated toxicities. METHODS: Postmenopausal women diagnosed with breast or gynecologic cancer and low baseline FSFI desire scores (< 3.3), who had completed definitive cancer therapy, were eligible. Women were randomly assigned to receive 150 mg or 300 mg once daily of extended-release bupropion or a matching placebo. t-tests were performed on the FSFI desire subscale to evaluate whether there was a significantly greater change from baseline to 9 weeks between placebo and each bupropion arm as the primary end point. Sixty-two patients per arm provided 80% power using a one-sided t-test. RESULTS: Two hundred thirty women were randomly assigned from 72 institutions through the NRG Oncology NCORP network. At 9 weeks, there were no statistically significant differences in change of the desire subscale scores between groups; participants in all three arms reported improvement. The mean changes for each arm were placebo 0.62 (standard deviation [SD] = 1.18), 150-mg once daily bupropion 0.64 (SD = 0.95), and 300-mg once daily bupropion 0.60 (SD = 0.89). Total and subscale scores on the FSFI were low throughout the study, indicating dysfunction in all groups. CONCLUSION: Bupropion was not more effective than placebo in improving the desire subscale of the FSFI. Subscale and total scores of the FSFI demonstrated dysfunction throughout the 9 weeks of the study. More research is needed to support sexual function in female cancer survivors.

RESUMEN

How do oncologists choose therapy for the elderly? Oncologists assigned patients aged 65 years or older with incurable non-small cell lung cancer to: (a) carboplatin (AUC = 2) + paclitaxel 50 mg/m(2) days 1, 8, 15 (28-day cycle × 4) followed by gefitinib; or (b) gefitinib 250 mg/day. With (a), 12 of 34 were progression-free at 6 months; median time to cancer progression was 3.9 months. With (b), the same occurred in 11 of 28 patients with the latter being 4.9 months. The most common reason for conventional chemotherapy was oncologists' opinion that the cancer was aggressive, and for gefitinib alone, patients' reluctance to receive chemotherapy. Interestingly, age had no influence.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) continues to be a substantial problem for many cancer patients. Pursuant to promising appearing pilot data, the current study evaluated the use of vitamin E for the prevention of CIPN. METHODS: A phase III, randomized, double-blind, placebo-controlled study was conducted in patients undergoing therapy with neurotoxic chemotherapy, utilizing twice daily dosing of vitamin E (400 mg)/placebo. The primary endpoint was the incidence of grade 2+ sensory neuropathy (SN) toxicity (CTCAE v 3.0) in each treatment arm, analyzed by chi-square testing. Planned sample size was 100 patients per arm to provide 80% power to detect a difference in incidence of grade 2+ SN toxicity from 25% in the placebo group to 10% in the vitamin E group. RESULTS: Two-hundred seven patients were enrolled between December 1, 2006 and December 14, 2007, producing 189 evaluable cases for analysis. Cytotoxic agents included taxanes (109), cisplatin (8), carboplatin (2), oxaliplatin (50), or combination (20). There was no difference in the incidence of grade 2+ SN between the two arms (34%-vitamin E, 29%-placebo; P = 0.43). There were no significant differences between treatment arms for time to onset of neuropathy (P = 0.58), for chemotherapy dose reductions due to neuropathy (P = 0.21), or for secondary endpoints derived from patient-reported neuropathy symptom assessments. The treatment was well tolerated overall. CONCLUSIONS: Vitamin E did not appear to reduce the incidence of sensory neuropathy in the studied group of patients receiving neurotoxic chemotherapy.

RESUMEN

PURPOSE: Previous studies suggest tetracycline and other antibiotics lessen the severity of epidermal growth factor receptor (EGFR) inhibitor-induced rash. This study sought to confirm such findings. METHODS: Patients starting an EGFR inhibitor were eligible for this randomized, double-blinded, placebo-controlled study and had to be rash-free. They were then randomly assigned to tetracycline 500 mg orally twice a day for 28 days versus a placebo. Rash development and severity (monthly physician assessment and weekly patient-reported questionnaires), quality of life (SKINDEX-16), and adverse events were monitored during the 4-week intervention and then for an additional 4 weeks. The primary objective was to compare the incidence of grade 2 or worse rash between study arms; 32 patients per group provided a 90% probability of detecting a 40% difference in incidence with a type I error rate of 0.05 (two-sided). RESULTS: Sixty-five patients were enrolled, and groups were balanced on baseline characteristics. During the first 4 weeks, healthcare provider-reported data found that 27 tetracycline-treated patients (82%) and 24 placebo-exposed patients (75%) developed a rash. This rash was a grade 2+ in 17 (52%) and 14 (44%), respectively (p = 0.62). Comparable grade 2+ rash rates were observed during weeks 5 through 8 as well as with patient-reported rash data throughout the study period. Quality of life was comparable across study arms, and tetracycline was well tolerated. CONCLUSION: Although previous studies suggest otherwise, this randomized, double-blinded, placebo-controlled study did not find that tetracycline lessened rash incidence or severity in patients who were taking EGFR inhibitors.

RESUMEN

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a troublesome chronic symptom that has no proven pharmacologic treatment. The purpose of this double-blind randomized placebo-controlled trial was to evaluate a novel compounded topical gel for this problem. METHODS: Patients with CIPN were randomized to baclofen 10 mg, amitriptyline HCL 40 mg, and ketamine 20 mg in a pluronic lecithin organogel (BAK-PLO) versus placebo (PLO) to determine its effect on numbness, tingling, pain, and function. The primary endpoint was the baseline-adjusted sensory subscale of the EORTC QLQ-CIPN20, at 4 weeks. RESULTS: Data in 208 patients reveal a trend for improvement that is greater in the BAK-PLO arm over placebo in both the sensory (p = 0.053) and motor subscales (p = 0.021). The greatest improvements were related to the symptoms of tingling, cramping, and shooting/burning pain in the hands as well as difficulty in holding a pen. There were no undesirable toxicities associated with the BAK-PLO and no evidence of systemic toxicity. CONCLUSION: Topical treatment with BAK-PLO appears to somewhat improve symptoms of CIPN. This topical gel was well tolerated, without evident systemic toxicity. Further research is needed with increased doses to better clarify the clinical role of this treatment in CIPN.

RESUMEN

The purpose of this trial was to determine cardiac toxicity and overall efficacy of the pegylated liposome doxorubicin (PLD)-docetaxel couplet alone if HER2-negative metastatic breast cancer (internal control) or with trastuzumab if HER2-positive disease. Upon central HER2 confirmation, 84 eligible patients received induction with PLD (30 mg/m(2)) and docetaxel (60 mg/m(2)) every 3 weeks (maximum eight cycles), alone if HER2-negative (arm A; N = 38) or plus trastuzumab (4 mg/kg once, then 2 mg/kg weekly) if HER2-positive disease (arm B; N = 46) as first-line therapy. Maintenance therapy (without PLD) allowed. Primary objectives were to determine whether congestive heart failure (CHF) rate >3% and the efficacy/toxicity of each arm. CHF rate was <3% in each arm. Response rate, median progression-free-, and overall survival in arms A and B were 47.4 and 45.7%, 11 and 10.6 months, and 24.6 and 31.8 months, respectively. Trastuzumab arm was associated with higher rates of hand foot syndrome (grade 3: 22 vs. 38%; P = 0.16; overall 51 vs. 75%, P = 0.03) and treatment discontinuation due to toxicity/patient withdrawal (13 vs. 28%; P = 0.11). Febrile neutropenia occurred in approximately 10% of patients. In conclusion, concurrent administration of trastuzumab with PLD-docetaxel was not associated with higher risk of cardiac toxicity compared with PLD-docetaxel alone, but led to excessive hand-foot syndrome.

RESUMEN

OBJECTIVES: Randomized phase 3 trials have demonstrated the utility of a regimen of carboplatin plus pegylated liposomal doxorubicin (PLD) in recurrent ovarian cancer, and have provided provocative data suggesting a substantially lower risk of carboplatin-associated hypersensitivity if PDL is delivered in combination with the platinum agent. METHODS: To further examine both of these clinically-relevant issues, the survival outcome (with longer follow-up) and hypersensitivity reaction profile of a previously reported phase 3 trial that compared single agent carboplatin (AUC 5) to carboplatin (AUC 5) plus PLD (30 mg/m(2)) delivered on an every 4-week schedule in recurrent ovarian cancer (SWOG 0200) were re-analyzed. RESULTS: In the limited number of patients (n=61) entered into this phase 3 study before closure by the SWOG Data Safety and Monitoring Committee due to insufficient accrual, there was an initially reported improvement in outcome associated with the combination regimen. With longer follow-up and additional events there is still a statistically-significant improved progression-free survival (median: 12 versus 8 months, p=0.02), but the previously observed impact of the two-drug regimen on overall survival is no longer apparent (median: 31 versus 18 months; p=0.2). While no hypersensitivity reactions were reported in the carboplatin plus PLD arm (0/31), 9 of 30 patients (30%) of women randomized to single agent carboplatin experienced an allergic episode (p=0.0008), with 5 being >grade 2 in severity. CONCLUSION: Despite a favorable impact of carboplatin and PLD on progression-free survival in this trial, the effect on overall survival is not statistically significant. For currently unknown reasons, administering PLD with carboplatin appears to substantially reduce the incidence of platinum-associated hypersensitivity reactions.

RESUMEN

Hot flashes are a complication of androgen deprivation therapy for prostate cancer. A phase III study showed that use of low-dose gabapentin was well tolerated and moderately decreased the frequency of hot flashes due to androgen deprivation therapy when taken for 4 weeks. The current study, an open-label continuation of the randomized study, examined the efficacy and toxicity of gabapentin when taken for (an additional) 8 weeks. Patients were allowed to start, or continue, gabapentin and to titrate the dose to maximum efficacy, up to 900 mg/d. They were asked to complete a hot flash diary daily and keep weekly logs of toxicity, satisfaction with hot flash control, and quality of life. The moderate reduction in hot flash frequency and severity in the randomized phase of the study appeared to be maintained during this continuation phase. Men originally receiving the placebo or lowest dose of gabapentin (300 mg/d) had improved hot flash control relative to that at the end of the randomized phase. Minimal adverse effects were reported. These findings suggest that low-dose gabapentin is moderately efficacious for at least 12 weeks of hot flash treatment in men undergoing androgen deprivation therapy for prostate cancer and seems to be well tolerated.

RESUMEN

PURPOSE: The purpose of this study is to test the ability of risedronate and estradiol, alone or in combination, to prevent bone loss associated with androgen deprivation therapy in men with prostate cancer. MATERIALS AND METHODS: This is a randomized placebo-controlled trial of risedronate and estradiol, alone or in combination, in men with prostate cancer receiving androgen deprivation therapy. The primary outcome was change in hip bone mineral density at 1 year. RESULTS: No statistical difference was found among the groups for bone mineral density changes. The only side effects of note were increased gynecomastia and breast tenderness associated with estrogen therapy. The study was limited by poor accrual and subsequent lack of statistical power. CONCLUSIONS: Men receiving androgen deprivation therapy for prostate cancer are at risk for bone loss and should receive appropriate bone density monitoring and preventive advice about calcium, vitamin D, exercise, and fall prevention. Prescription drugs proven in this patient population should be used when the risk of fracture is high.

RESUMEN

A 73-year-old woman was brought to the oestrogen receptor for altered mental status. She was found to be hypotensive and hypoglycaemic and admitted to the intensive care unit. She had a history of chronic watery diarrhoea which had recently increased over the last 2 weeks and was associated with vague abdominal pain. A CT showed bowel wall thickening concerning for colitis. Due to the increasing diarrhoea, a colonoscopy was done after all stool studies came back negative. Polyps in the ascending, transverse and sigmoid colon were found to be tubular adenomas but random colonic mucosa biopsies were revealed to be histologically consistent with metastatic lobular breast carcinoma. Further workup revealed no primary breast disease.
