Abstract
Background Combination irinotecan and cetuximab is approved for irinotecan-refractory metastatic colorectal cancer (mCRC). It is unknown if adding bevacizumab improves outcomes. Patients and Methods In this multicenter, randomized, double-blind, placebo-controlled phase II trial, patients with irinotecan-refractory RAS-wildtype mCRC and no prior anti-EGFR therapy were randomized to cetuximab 500 mg/m2, bevacizumab 5 mg/kg, and irinotecan 180 mg/m2 (or previously tolerated dose) (CBI) versus cetuximab, irinotecan, and placebo (CI) every 2 weeks until disease progression or intolerable toxicity. The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), objective response rate (ORR), and adverse events (AEs). Results The study closed early after the accrual of 36 out of a planned 120 patients due to changes in funding. Nineteen patients were randomized to CBI and 17 to CI. Baseline characteristics were similar between arms. Median PFS was 9.7 versus 5.5 months for CBI and CI, respectively (1-sided log-rank P = .38; adjusted hazard ratio [HR] = 0.64; 95% confidence interval [CI], 0.25-1.66). Median OS was 19.7 versus 10.2 months for CBI and CI (1-sided log-rank P = .02; adjusted HR = 0.41; 95% CI, 0.15-1.09). ORR was 36.8% for CBI versus 11.8% for CI (P = .13). Grade 3 or higher AEs occurred in 47% of patients receiving CBI versus 35% for CI (P = .46). Conclusion In this prematurely discontinued trial, there was no significant difference in the primary endpoint of PFS between CBI and CI. There was a statistically significant improvement in OS in favor of CBI compared with CI. Further investigation of CBI for the treatment of irinotecan-refractory mCRC is warranted.

Abstract
1016 Background: The ph III EMBRACE trial of E vs physician’s choice of tx led to FDA approval of E as ≥3rd-line tx for MBC pts with prior exposure to anthracyclines/taxanes. The ph III BOLD 301 trial of E vs capecitabine in advanced BC treated with anthracyclines/taxanes showed a nonsignificant trend to improved median OS for all pts; pre-planned analysis by HER2 status revealed a nominally significant benefit for HER2- pts. Methods: RU011201I is an investigator initiated ph III trial with 1:1 randomization to E (1.4 mg/m2 D1,8 q21days) vs P (90 mg/m2 D1,8,15 q28days) within strata defined by (neo)adjuvant taxanes (yes/no), HR status (+/-), and line of tx (1st/2nd). Pts had measurable or non-measurable disease by RECIST v1.1; new or progressive mets; peripheral neuropathy (PN) gr<2; ≤1 prior chemotx regimens for advanced or MBC. Asymptomatic brain mets with stable MRIs for >3 mos were allowed. (Neo)adjuvant taxanes were allowed if >12 mos between tx completion and disease recurrence. Radiographic studies occur q12wks. Survival data are collected q12wks after the Off-Tx Visit. Pts reported side effects weekly; post-baseline symptomatic AE rates worse than baseline were compared between arms using Fisher’s exact tests. We report clinical outcomes and the primary objective related to PRO-CTCAE use. Results: 201 pts enrolled 3/2014 - 5/2018 with 33.8 mos median f/u; 3 are on tx as of 2/20/20 (1E, 2P). Pt characteristics were the same between E vs P: median age 62 yrs (range 27-85); 42% prior taxane; 78% ER+; 70% starting 1st line tx. Baseline lesion distribution was similar except for lung mets (37E, 53P). No difference was seen between E vs P in PFS (5.7 vs 5.9 mos; P=0.72), OS (18.1 vs 16.4 mos; P=0.75), TTF (5.3 vs 4.9 mos; P=0.82), DOR (10.8 vs 12.3 mos; P=0.84), or number of metastatic events (55 vs 54). 37E and 36P pts required ≥1 dose reduction. Hematologic toxicities ≥ gr 3 were higher with E (40 vs 22%). PN events were similar: 56 vs 58 total, 4 vs 7 motor, 52 vs 51 sensory. Median duration of PN and median time to 1st PN event were 74 vs 140 and 56 vs 41 days. Worsened numbness/tingling severity and other pt-reported AE rates were similar, but worsened numbness/tingling interference (63% vs 78%, P=0.04) and vomiting frequency (35% vs 57%, P=0.005) were lower with E. Conclusions: Clinical outcomes were equivalent with E vs P as 1st/2nd line tx for HER2- advanced BC. The nature and severity of PN were similar between arms, but time of onset, duration, and interference with daily living favor E. E may be a suitable treatment option in this setting.

Abstract
102 Background: Combination irinotecan and cetuximab is approved for irinotecan-refractory mCRC; it is unknown if the addition of bevacizumab would improve outcomes. We studied the efficacy and safety of CBI compared with CI in patients (pts) with RAS wildtype, irinotecan-refractory mCRC. Methods: In this multicenter, randomized, double-blind, placebo-controlled phase II trial, pts with RAS wildtype mCRC and no prior anti-epidermal growth factor receptor therapy who failed at least 1 irinotecan-based chemotherapy regimen and received bevacizumab in at least 1 prior line of therapy were randomized 1:1 to irinotecan 180 mg/m2 (or previously tolerated dose), cetuximab 500 mg/m2, and bevacizumab 5 mg/kg vs CI every 2 wks until disease progression, intolerable toxicity, or withdrawal of consent. The primary endpoint was progression free survival (PFS). Multivariable Cox proportional hazard models stratified by number of prior lines of therapy and bevacizumab receipt in immediate prior line were performed. Secondary endpoints included overall survival (OS), objective response rate (ORR), and adverse events (AEs). The study was closed early in January 2018 for reasons related to accrual and funding after enrollment of 36 out of a planned 60 pts. Results: Between July 2015 and December 2017, 36 pts were randomized (19 to CBI, 17 to CI). 34 pts (94%) were treated with 2 or more prior chemotherapy regimens. Baseline characteristics were similar between arms. Median PFS was 9.7 vs 5.5 mo for CBI and CI arms, respectively (log-rank P =0.76; multivariable HR = 0.64; 95% CI, 0.25-1.66). Median OS was 19.7 vs 10.2 mo for CBI and CI (log-rank P= 0.04; multivariable HR = 0.41; 95% CI, 0.15-1.09). ORR was 37% for CBI vs 12% for CI ( P =0.13). Grade 3 or higher AEs occurred in 47% of pts receiving CBI vs 35% for CI ( P =0.46). Conclusions: In this prematurely discontinued trial, there were non-significant increases in PFS and ORR and a statistically significant 9.5 mo increase in median OS in favor of CBI compared to CI. Further investigation of CBI for treatment of irinotecan-refractory mCRC is warranted. Clinical trial information: NCT02292758.

Abstract
BACKGROUND We conducted this trial to determine the maximum tolerated dose (MTD) of temsirolimus added to an established regimen comprised of rituximab and cladribine for the initial treatment of mantle cell lymphoma. PATIENTS AND METHODS A standard phase I cohort of three study design was utilized. The fixed doses of rituximab and cladribine were 375 mg/m(2) i.v. day 1 and 5 mg/m(2)/day i.v. days 1-5 of a 28-day cycle, respectively. There were five planned temsirolimus i.v. dose levels: 15 mg day 1; 25 mg day 1; 25 mg days 1 and 15; 25 mg days 1, 8 and 15; and 25 mg days 1, 8, 15, and 22. RESULTS Seventeen patients were treated: three each at levels 1-4 and five at dose level 5. The median age was 75 years (52-86 years). Mantle Cell International Prognostic Index (MIPI) scores were low in 6% (1), intermediate in 59% (10), and high in 35% (6) of patients. Five patients were treated at level 5 without dose limiting toxicity. Hematologic toxicity was frequent: grade 3 anemia in 12%, grade 3 thrombocytopenia in 41%, grade 4 thrombocytopenia in 24%, grade 3 neutropenia in 6%, and grade 4 neutropenia in 18% of patients. The overall response rate (ORR) was 94% with 53% complete response and 41% partial response. The median progression-free survival was 18.7 months. CONCLUSIONS Temsirolimus 25 mg i.v. weekly may be safely added to rituximab and cladribine at 375 mg/m(2) i.v. day 1 and 5 mg/m(2)/day i.v. days 1-5 of a 28-day cycle, respectively. This regimen had promising preliminary activity in an elderly cohort of patients with mantle cell lymphoma. CLINICALTRIALSGOV IDENTIFIER NCT00787969.

Abstract
PURPOSE Pelvic radiotherapy (PRT) is known to adversely affect bowel function (BF) and patient well-being. This study characterized long-term BF and evaluated quality of life (QOL) in patients receiving PRT. METHODS Data from 252 patients were compiled from two North Central Cancer Treatment Group prospective studies, which included assessment of BF and QOL by the BF questionnaire (BFQ) and Uniscale QOL at baseline and 12 and 24 months after completion of radiotherapy. BFQ scores (sum of symptoms), Uniscale results, adverse-event incidence, and baseline demographic data were compared via t test, χ (2), Fisher exact, Wilcoxon, and correlation methodologies. RESULTS The total BFQ score was higher than baseline at 12 and 24 months (P < 0.001). More patients had five or more symptoms at 12 months (13 %) and 24 months (10 %) than at baseline (2 %). Symptoms occurring in greater than 20 % of patients at 12 and 24 months were clustering, stool-gas confusion, and urgency. Factors associated with worse BF were female sex, rectal or gynecologic primary tumors, prior anterior resection of the rectum, and 5-fluorouracil chemotherapy. Patients experiencing grade 2 or higher acute toxicity had worse 24-month BF (P values, <.001-.02). Uniscale QOL was not significantly different from baseline at 12 or 24 months, despite worse BFQ scores. CONCLUSIONS PRT was associated with worse long-term BF. Worse BFQ score was not associated with poorer QOL. Further research to characterize the subset of patients at risk of significant decline in BF is warranted.

Abstract
BACKGROUND The current study was conducted to assess the efficacy and toxicity of sorafenib as front-line therapy in patients with stage IIIB (pleural effusion) or IV nonsmall cell lung cancer (NSCLC). METHODS Patients received sorafenib 400 mg twice daily by mouth continuously, and were evaluated every 2 weeks during the first 8 weeks. Patients who manifested clinical progression during this period proceeded to receive standard of care. The primary endpoint was confirmed objective tumor response. A 2-stage Fleming design was used such that if at most 1 confirmed partial response (PR) or complete response was observed in the first 20 patients (stage 1), the treatment would be considered ineffective, and further enrollment would be discontinued. RESULTS Only 1 PR was observed in the first 20 patients. By the time of study closure, 5 additional patients who were already being screened for study inclusion were enrolled. Of the 25 patients (15 women, 10 men; 4 stage IIIB, 21 stage IV; median age, 67 years [range, 45-85 years]), there were 3 (12%) PRs and 6 (24%) cases with stable disease observed. The median time-to-progression and progression-free survival was 2.8 months. Seven (28%) patients remained progression-free at 24 weeks. No grade 3 or higher hematologic adverse events were observed. Thirteen (52%) patients had a grade 3 nonhematologic adverse event, with fatigue (20%), diarrhea (8%), and dyspnea (8%) being the most common. CONCLUSIONS Sorafenib is not effective as front-line therapy in the general unselected NSCLC population. The window of opportunity design is feasible for estimating the activity of novel compounds.

Intravenous calcium and magnesium for oxaliplatin-induced sensory neurotoxicity in adjuvant colon cancer: NCCTG N04C7. J Clin Oncol 2011; 29:421-7.

Abstract
PURPOSE Cumulative sensory neurotoxicity (sNT) is the dose-limiting toxicity of oxaliplatin, which commonly leads to early discontinuation of oxaliplatin-based therapy in the palliative and adjuvant settings. In a nonrandomized, retrospective study, intravenous (IV) calcium/magnesium (Ca/Mg) was associated with reduced oxaliplatin-induced sNT. METHODS Patients with colon cancer undergoing adjuvant therapy with infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX) were randomly assigned to Ca/Mg (1g calcium gluconate plus 1g magnesium sulfate pre- and post-oxaliplatin) or placebo, in a double-blinded manner. The primary end point was the percentage of patients with grade 2 or greater sNT at any time during or after oxaliplatin-based therapy by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE; version 3) criteria. An oxaliplatin-specific sNT scale and patient questionnaires were also used to assess sNT. After 104 of 300 planned patients were enrolled, the study was closed. This was due to preliminary reports from another trial that suggested that Ca/Mg decreased treatment efficacy; these data were subsequently found to be incorrect. RESULTS Overall, 102 patients were available for analysis. Ca/Mg decreased the incidence of chronic, cumulative, grade 2 or greater sNT, as measured by NCI CTCAE (P = .038) and also by the oxaliplatin-specific sNT scale (P = .018). In addition, acute muscle spasms associated with oxaliplatin were significantly reduced (P = .01) No effect on acute, cold-induced sNT was found. No substantial differences in adverse effects were noted between Ca/Mg and placebo. CONCLUSION Despite early termination and decreased statistical power, this study supports IV Ca/Mg as an effective neuroprotectant against oxaliplatin-induced cumulative sNT in adjuvant colon cancer.

Abstract
Irinotecan has radiosensitizing effects and shows synergism with nitrosoureas. We performed a Phase II study of RT and irinotecan, followed by BCNU plus irinotecan in newly-diagnosed GBM. The MTD for patients receiving enzyme-inducing anticonvulsants (EIAC) was as follows: irinotecan 400 mg/m(2)/week on Days 1, 8, 22 and 29 during RT, followed by BCNU 100 mg/m(2) Day 1, and irinotecan, 400 mg/m(2) on Days 1, 8, 22 and 29, every 6 weeks. The MTD for non-EIAC patients was as follows: irinotecan 125 mg/m(2)/week on Days 1, 8, 22 and 29 during RT, followed by BCNU 100 mg/m(2) Day 1 and irinotecan 75 mg/m(2) Days 1, 8, 22 and 29, every 6 weeks. Median OS was 10.8 mos. (95% CI: 7.7-14.9); OS at 12 months was 44.6% (95% CI: 33.3-59.8) and PFS 6 was 28.6% (95% CI: 18.9-43.2). Patients went off treatment due to adverse events (7%), refusal (11%), progressive disease (48%), death (9%), and other (9%); 16% completed protocol treatment. Survival was similar in patients with variant (6/7 or 7/7) and wild-type (6/6) UGT1A1*28 genotypic alleles. Grade 3-4 toxicity was more common in non-EIAC patients with variant alleles. SN-38 C(max) and AUC in EIAC patients receiving 400 mg/m(2) irinotecan were 20.9 ng/ml and 212 ng/ml h, and in non-EIAC patients receiving 125 mg/m(2), 15.5 ng/ml and 207 ng/ml h. SN-38 AUC varied by UGT1A1*28 status in non-EIAC patients. This regimen was not significantly active and radiosensitization was not observed. Non-EIAC patients with UGT1A1*28 variant alleles appear particularly sensitive to toxicity from irinotecan.

Abstract #2109
Background: Despite the impressive results of the recently released trastuzumab adjuvant therapy trials, 15% of patients with HER2 overexpressing or amplified breast cancer developed tumor relapse at 4 years. Lapatinib is a small molecule reversible TKI that inhibits both ErbB1 and ErbB2. The current study was developed to assess the cardiac safety and feasibility of adding lapatinib to paclitaxel and trastuzumab following as part of adjuvant therapy.
 Methods: A single-arm phase II study of doxorubicin (A, 60 mg/m2 day 1) and cyclophosphamide (C, 600 mg/m2 day 1) [q2w or q3w for 4 cycles]; followed by paclitaxel (P, 80 mg/m2 days 1, 8, 15), trastuzumab (T, 4 mg/kg loading dose then 2 mg/kg days 1, 8, 15), and lapatinib (L, 1000 mg days 1-21) [12 weeks]; followed by T (6 mg/kg day 1) and L (1000 mg days 1-21) [40 weeks] was conducted. The primary endpoint was the incidence of congestive heart failure. The current unplanned safety analysis was undertaken due to the observance of a high rate of G3/4 diarrhea.
 Results: From April 2007 to June 2008, 98 pts were enrolled and initiated study treatment. Median age was 51 (range 32-72). Among 83 pts with adverse event (AE) data available, 50 (60%) pts have experienced a G3/4 non-hematologic AE. During post-AC treatment, among 53 pts with AE data available, 31 (58.5%) patients have experienced a G3/4 non-hematologic AE with 24 (45%) patients reporting G3/4 diarrhea. Median cycle of onset of G3/4 diarrhea was cycle 5 (first cycle of PTL) with 16 (64%) cases first reported during cycle 5 and 5 (20%) cases first reported during cycle 6. Among 57, 46, 38, and 32 pts receiving treatment with PTL during cycles 5-8, 65%, 57%, 61%, and 72% of patients received the full L dose, respectively. 31 patients have ended active treatment with 10 due to patient refusal and 8 due to adverse events.
 Conclusions: Preliminary data suggest that L given concurrently with P and T at a dose of 1000 mg per day induces an unacceptable rate of moderate to severe diarrhea. Careful monitoring of diarrhea as well as L dose reduction and initiation of loperamide at first occurrence of diarrhea are recommended. The dose of L when given concurrently with P and T has been amended to 750 mg per day in the current study and safety data for the 1000 mg and 750 mg per day cohorts will be presented. Implications for the ongoing ALTTO study will also be presented.

Abstract
BACKGROUND Tumor necrosis factor-alpha (TNF-alpha) is a putative mediator of the cancer anorexia/weight loss syndrome. The current study was designed to determine whether etanercept (a dimeric fusion protein consisting of the extracellular ligand-binding portion of the human 75-kilodalton TNF receptor linked to the Fc portion of human immunoglobulin [Ig] G1) could palliate this syndrome. METHODS A total of 63 evaluable patients were randomly assigned to receive either etanercept at a dose of 25 mg subcutaneously twice weekly versus a comparably administered placebo. All patients had an incurable malignancy, acknowledged loss of weight and/or appetite as a concern, and reported a weight loss of >2.27 kg over 2 months and/or a daily intake of <20 calories/kg body weight. RESULTS Over time, weight gain was found to be minimal in both treatment arms; no patient gained >or=10% of their baseline weight. Previously validated appetite questionnaires revealed negligible improvements in both treatment arms. The median survival was also comparable (175 days vs 148 days in etanercept-treated and placebo-exposed patients, respectively; P = .82). Finally, preliminary data regarding adverse events demonstrated that patients treated with etanercept had higher rates of neurotoxicity (29% vs 0%) but lower rates of anemia (0% vs 19%) and thrombocytopenia (0% vs 14%). Infection rates were negligible in both groups. Genotyping for TNF-alpha-238 and TNF-alpha-308 polymorphisms revealed no clinical significance for these genotypes, except for a preliminary association between presence of the -238 G/A genotype and relatively less favorable survival. CONCLUSIONS Etanercept, as prescribed in the current trial, does not appear to palliate the cancer anorexia/weight loss syndrome in patients with advanced disease.

Abstract
Purpose To evaluate the outcome of patients with limited-stage small-cell lung cancer (L-SCLC) treated with cisplatin and etoposide (PE), early prophylactic cranial irradiation (PCI), and high-dose twice-daily thoracic radiotherapy (bid RT). Patients and Methods A total of 76 assessable patients were treated on this phase II trial, which included six cycles of PE. PCI (25 Gy/10 fractions) was delivered during cycle 3 to responding patients. Cycles 4 and 5 included concurrent chemotherapy and thoracic RT (30 Gy/20 bid fractions, a 2-week break, and another 30 Gy/20 bid fractions). Results Of the 76 assessable patients, 74 patients (97%) suffered grade 3 or greater (3+) toxicity and 61 patients (80%) had grade 4 or greater (4+) toxicity. Of these adverse events, grade 3+ hematologic toxicity occurred in 72 patients (95%), and grade 3+ nonhematologic toxicity occurred in 55 patients (72%). Only one (2%) of the 61 patients who received PCI experienced treatment failure in the brain. The 5-year survival rate of the 76 assessable patients was 24% (median, 20 months). The 5-year survival rate of the 64 patients who received thoracic RT was 29% (median, 22 months). The 5-year cumulative incidence of in-field treatment failure was 34%. Conclusion This regimen included a high total dose of bid TRT, which resulted in a favorable 5-year survival rate. Local failure remains a problem that will require additional investigation. Newer technology should allow the safe administration of greater doses of RT, which should improve patient outcome. Data from eight trials were combined to demonstrate a relationship between RT dose fractionation and 5-year survival.

Abstract
BACKGROUND Decreased libido is one of several changes in sexual function that are often experienced by female cancer patients. Transdermal testosterone therapy has been associated with increased libido among estrogen-replete women who report low libido. METHODS In a phase III randomized, placebo-controlled crossover clinical trial, we evaluated whether transdermal testosterone would increase sexual desire in female cancer survivors. Postmenopausal women with a history of cancer and no current evidence of disease were eligible if they reported a decrease in sexual desire and had a sexual partner. Eligible women were randomly assigned to receive 2% testosterone in Vanicream for a testosterone dose of 10 mg daily or placebo Vanicream for 4 weeks and were then crossed over to the opposite treatment for an additional 4 weeks. The primary endpoint was sexual desire or libido, as measured using the desire subscales of the Changes in Sexual Functioning Questionnaire, as assessed at baseline and at the end of 4 and 8 weeks of treatment. Serum levels of bioavailable testosterone were measured at the same times. All statistical tests were two-sided. RESULTS We enrolled 150 women. Women who were on active testosterone cream had higher serum levels of bioavailable testosterone than women on placebo (mean change from baseline, testosterone versus placebo, week 4, 11.57% versus 0%, difference = 11.57%, 95% confidence interval [CI] = 8.49% to 14.65%; week 8, 10.21% versus 0.28%, difference = 9.92%, 95% CI = 5.42% to 14.42%; P<.001 for all). However, the average intrapatient libido change from baseline to weeks 4 and 8 was similar on both arms. CONCLUSION Increased testosterone level did not translate into improved libido, possibly because women on this study were estrogen depleted.

Phase I North Central Cancer Treatment Group Trial-N9923 of escalating doses of twice-daily thoracic radiation therapy with amifostine and with alternating chemotherapy in limited stage small-cell lung cancer. Int J Radiat Oncol Biol Phys 2007; 67:995-1001. [PMID: 17336213 DOI: 10.1016/j.ijrobp.2006.10.034] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2006] [Revised: 10/02/2006] [Accepted: 10/03/2006] [Indexed: 11/30/2022]
Abstract
PURPOSE The primary goal was to identify the maximum tolerable dose (MTD) of thoracic radiation therapy (TRT) that can be given with chemotherapy and amifostine for patients with limited-stage small-cell lung cancer (LSCLC). METHODS AND MATERIALS Treatment began with two cycles of topotecan (1 mg/m(2)) Days 1 to 5 and paclitaxel (175 mg/m(2)) Day 5 (every 3 weeks) given before and after TRT. The TRT began at 6 weeks. The TRT was given in 120 cGy fractions b.i.d. and the dose escalation (from 4,800 cGy, dose level 1, to 6,600 cGy, dose level 4) followed the standard "cohorts of 3" design. The etoposide (E) (50 mg/day) and cisplatin (C) (3 mg/m(2)) were given i.v. before the morning TRT and amifostine (500 mg/day) was given before the afternoon RT. This was followed by prophylactic cranial irradiation (PCI). The dose-limiting toxicities (DLTs) were defined as Grade > or =4 hematologic, febrile neutropenia, esophagitis, or other nonhematologic toxicity, Grade > or =3 dyspnea, or Grade > or =2 pneumonitis. RESULTS Fifteen patients were evaluable for the Phase I portion of the trial. No DLTs were seen at dose levels 1 and 2. Two patients on dose level 4 experienced DLTs: 1 patient had a Grade 4 pneumonitis, dyspnea, fatigue, hypokalemia, and anorexia, and 1 patient had a Grade 5 hypoxia attributable to TRT. One of 6 patients on dose level 3 had a DLT, Grade 3 esophagitis. The Grade > or =3 toxicities seen in at least 10% of patients during TRT were esophagitis (53%), leukopenia (33%), dehydration (20%), neutropenia (13%), and fatigue (13%). The median survival was 14.5 months. CONCLUSION The MTD of b.i.d. TRT was 6000 cGy (120 cGy b.i.d.) with EP and amifostine.

Abstract
OBJECTIVE To compare the combination of a nicotine inhaler and bupropion to either treatment alone for initiating smoking abstinence and relapse prevention. METHODS Smokers were randomized to receive a nicotine inhaler, bupropion, or both for 3 months. At 3 months, smoking-abstinent study participants were randomized to their initial medications or placebo. Participants who were smoking at 3 months were randomized to an alternative treatment regimen or placebo. This study was conducted from July 2001 to January 2003. RESULTS A total of 1700 smokers were randomized to treatment (phase 1) for 3 months. Among the 941 study participants eligible for randomization to the phase 2 trial, 837 continued in the study. For the phase 2 trial, 405 smoking-abstinent participants were randomized to relapse prevention for 9 additional months, and 432 smokers were randomized to re-treatment for an additional 3 months. At the end of the initial 3 months of treatment (phase 1), 82 (14%) of 566, 145 (26%) of 567, and 194 (34%) of 567 study participants receiving a nicotine inhaler, bupropion, or both, respectively, were abstinent from smoking. Of the 405 smoking-abstinent participants at the end of 3 months, the bupropion group had more smokers than the placebo group (mean No. of smokers, 1.5 vs 1.1; P < .001), and the nicotine inhaler group had higher smoking abstinence rates at 12 months than the placebo group. Those receiving combination therapy had reduced rates of relapse to smoking for the first 3 months of relapse prevention, but this difference disappeared after the initial 3 months. Of the 432 study participants who were smoking at the end of 3 months and who received an alternative treatment regimen, the 223 smokers initially assigned to a nicotine inhaler were more likely to stop smoking at 6 months if they were re-treated with bupropion instead of placebo (8 [7%] of 111 vs 0 [0%] of 112; P = .003), and the 209 smokers initially treated with bupropion and re-treated with a nicotine inhaler did not have significantly higher smoking abstinence rates (6 [6%] of 104 vs 3 [3%] of 105; P = -.50). CONCLUSION Combined therapy with a nicotine inhaler and bupropion increased smoking abstinence rates. Continuation of the initial combination therapy does not appear to prevent relapse to smoking. Timing of re-treatment and alternative approaches to relapse prevention should be further examined.

The prevalence of weight concerns in a smoking abstinence clinical trial. Addict Behav 2006; 31:1144-52. [PMID: 16137833 DOI: 10.1016/j.addbeh.2005.08.011] [Citation(s) in RCA: 90] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2005] [Revised: 06/10/2005] [Accepted: 08/03/2005] [Indexed: 11/29/2022]
Abstract
Recent research has demonstrated there is a high prevalence of weight concerns in smokers and that smokers with weight concerns may respond poorly to treatment for tobacco dependence. Most studies have focused only on females or have consisted of small samples. In this study of a 12-week randomized trial of nicotine inhaler, bupropion or both for smoking cessation, 50% of the 1012 female smokers and 26% of the 680 male smokers, at study entry, were weight concerned. In examining the impact of weight concerns on the 12-week point-prevalence smoking abstinence, 26% of non-weight-concerned smokers quit smoking compared to 22% of weight-concerned smokers (p=0.06). This study, which includes a large sample of both genders, provides further evidence that approximately half of females who are seeking smoking cessation treatment are weight concerned and that one quarter of male smokers are weight concerned. Additionally, being weight concerned may impact the short-term success rates of stopping smoking using pharmacotherapy.

Abstract
The authors conducted a phase II study of somatostatin analogue in 18 patients with extensive stage small cell lung cancer (four with previous treatment, 14 without previous treatment). Patients received 2,000 mg subcutaneously thrice daily. They were required to have an Eastern Cooperative Oncology Group performance score of 0-2 and acceptable pretreatment biochemical parameters. No patient responded to treatment. The median time to progression was 44 days. The median survival was 106 days. Toxicity related to treatment consisted of mild diarrhea and anorexia. Somatostatin analogue is not active as a single agent in the treatment of extensive-stage small cell lung cancer.

Abstract
PURPOSE A minority of cancer survivors develops long-term postsurgical neuropathic pain. Based on evidence that capsaicin, the pungent ingredient in hot chili peppers, might be useful for treating neuropathic pain, we developed the present clinical trial. PATIENTS AND METHODS Ninety-nine assessable patients with postsurgical neuropathic pain were entered onto this study. After stratification, patients were to receive 8 weeks of a 0.075% capsaicin cream followed by 8 weeks of an identical-appearing placebo cream, or vice versa. A capsaicin/placebo cream was to be applied to the painful site four times daily. Treatment evaluation was performed by patient-completed weekly questionnaires. RESULTS During the first 8-week study period, the capsaicin-cream arm was associated with substantially more skin burning, skin redness, and coughing (P < .0001 for each). Nonetheless, treatment was stopped for patient refusal or toxicity just as often while patients were receiving the placebo as compared with the capsaicin. The capsaicin cream arm had substantially more pain relief (P = .01) after the first 8 weeks, with an average pain reduction of 53% versus 17%. On completion of the 16-week study period, patients were asked which treatment period was most beneficial. Of the responding patients, 60% chose the capsaicin arm, 18% chose the placebo arm, and 22% chose neither (P = .001). CONCLUSION A topical capsaicin cream decreases postsurgical neuropathic pain and, despite some toxicities, is preferred by patients over a placebo by a three-to-one margin among those expressing a preference.

Abstract
PURPOSE To evaluate the objective tumor response rate and toxicities of patients with metastatic colorectal carcinoma treated with irinotecan hydrochloride (CPT-11). PATIENTS AND METHODS A total of 121 patients with advanced colorectal carcinoma--90 with prior fluorouracil (5-FU) exposure and 31 chemotherapeutically naive patients--were enrolled between May 1993 and June 1994. Patients were treated with CPT-11 at 125 mg/m2 intravenously weekly for 4 weeks followed by a 2-week rest. RESULTS Among 90 patients with prior 5-FU chemotherapy, 12 partial responses were observed (response rate, 13.3%; 95% confidence interval [CI], 7.1% to 22.1%). Among 31 chemotherapy-naive patients, eight had partial responses (response rate, 25.8%; 95% CI, 11.9% to 44.6%). The median response duration as measured from time of initial treatment for the two groups was 7.7 months and 7.6 months, respectively. The major adverse reactions were gastrointestinal and hematologic. The incidence of grade 3 or 4 diarrhea was 36.4%, while the overall incidence of grade 3 or 4 leukopenia was 21.5% of patients. Only four of 121 patients (3.3%) developed neutropenic fever (grade 4 neutropenia with > or = grade 2 fever). The incidence of grade 4 leukopenia was higher in patients with prior pelvic radiotherapy (chi2 test P = .04), while the incidence of grade 3 or 4 diarrhea demonstrated no association with previous pelvic irradiation. CONCLUSION According to the study design, CPT-11 showed promising activity in chemotherapy-naive patients with advanced colorectal carcinoma and modest activity in patients with prior 5-FU exposure. The toxicity with this schedule appears manageable with appropriate dose modification for individual patient tolerance and an intensive loperamide regimen for the management of diarrhea. Care should be taken when treating patients with prior pelvic radiotherapy because of the increased risk of neutropenia.

Abstract
BACKGROUND This clinical trial was developed to determine whether ocular ice pack therapy would decrease 5-fluorouracil (5-FU)-induced ocular toxicity. METHODS Sixty-two patients who suffered from 5-FU-induced ocular toxicity, and were scheduled to receive another cycle of the chemotherapy that caused the ocular toxicity, were entered in this clinical trial. A randomized, crossover design was used, with patients documenting their ocular toxicity by the use of daily diaries. RESULTS The results from the first cycle of treatment suggested that ocular ice pack therapy decreased 5-FU-induced ocular toxicity (P = 0.056). The 38 evaluable patients in the crossover analyses demonstrated decreased ocular toxicity with ocular ice pack therapy (p = .001). The ocular ice pack therapy was well tolerated by most of the study participants. CONCLUSION Ocular ice pack therapy appears to lessen 5-FU-induced ocular toxicity to a clinically moderate degree. Better methods for decreasing 5-FU-induced ocular toxicity are necessary.

Abstract
The effects of low-dose estrogen oral contraceptives (OC) on the elimination of the oxidized benzodiazepines triazolam (TRZ) and alprazolam (ALP) and the conjugated benzodiazepines temazepam (TMZ) and lorazepam (LOR) were studied in two parallel crossover studies of 20 women each. Women taking OC steroids containing low doses of estrogen and women matched for age, weight, and cigarette smoking received single oral doses of TRZ (0.5 mg) and TMZ (30 mg) or ALP (1 mg) and LOR (2 mg). Kinetics were determined as plasma concentrations during 48 hr after dosing. OCs inhibited the metabolism of ALP: The AUC increased and the elimination rate constant was greater in users of OCs. For TRZ, which has an intermediate extraction ratio, the AUC was increased by OCs but not significantly so. In contrast, OCs decreased the AUC for TMZ and the elimination rate constants for LOR and TMZ. The AUC of LOR was not affected by OCs. Low-dose estrogen OCs may therefore inhibit the metabolism of some oxidized benzodiazepines and accelerate the metabolism of some conjugated benzodiazepines.
