Abstract
BACKGROUND Primary graft dysfunction (PGD) is the leading cause of early morbidity and mortality after lung transplantation. Accurate prediction of PGD risk could inform donor approaches and perioperative care planning. We sought to develop a clinically useful, generalizable PGD prediction model to aid in transplant decision-making. METHODS We derived a predictive model in a prospective cohort study of subjects from 2012 to 2018, followed by a single-center external validation. We used regularized (lasso) logistic regression to evaluate the predictive ability of clinically available PGD predictors and developed a user interface for clinical application. Using decision curve analysis, we quantified the net benefit of the model across a range of PGD risk thresholds and assessed model calibration and discrimination. RESULTS The PGD predictive model included distance from donor hospital to recipient transplant center, recipient age, predicted total lung capacity, lung allocation score (LAS), body mass index, pulmonary artery mean pressure, sex, and indication for transplant; donor age, sex, mechanism of death, and donor smoking status; and interaction terms for LAS and donor distance. The interface allows for real-time assessment of PGD risk for any donor/recipient combination. The model offers decision-making net benefit in the PGD risk range of 10% to 75% in the derivation centers and 2% to 10% in the validation cohort, a range incorporating the incidence in that cohort. CONCLUSION We developed a clinically useful PGD predictive algorithm across a range of PGD risk thresholds to support transplant decision-making, posttransplant care, and enrich samples for PGD treatment trials.

Abstract
Rationale: Primary graft dysfunction (PGD) is the leading cause of early morbidity and mortality after lung transplantation. Prior studies implicated proxy-defined donor smoking as a risk factor for PGD and mortality. Objectives: We aimed to more accurately assess the impact of donor smoke exposure on PGD and mortality using quantitative smoke exposure biomarkers. Methods: We performed a multicenter prospective cohort study of lung transplant recipients enrolled in the Lung Transplant Outcomes Group cohort between 2012 and 2018. PGD was defined as grade 3 at 48 or 72 hours after lung reperfusion. Donor smoking was defined using accepted thresholds of urinary biomarkers of nicotine exposure (cotinine) and tobacco-specific nitrosamine (4-[methylnitrosamino]-1-[3-pyridyl]-1-butanol [NNAL]) in addition to clinical history. The donor smoking-PGD association was assessed using logistic regression, and survival analysis was performed using inverse probability of exposure weighting according to smoking category. Measurements and Main Results: Active donor smoking prevalence varied by definition, with 34-43% based on urinary cotinine, 28% by urinary NNAL, and 37% by clinical documentation. The standardized risk of PGD associated with active donor smoking was higher across all definitions, with an absolute risk increase of 11.5% (95% confidence interval [CI], 3.8% to 19.2%) by urinary cotinine, 5.7% (95% CI, -3.4% to 14.9%) by urinary NNAL, and 6.5% (95% CI, -2.8% to 15.8%) defined clinically. Donor smoking was not associated with differential post-lung transplant survival using any definition. Conclusions: Donor smoking associates with a modest increase in PGD risk but not with increased recipient mortality. Use of lungs from smokers is likely safe and may increase lung donor availability. Clinical trial registered with www.clinicaltrials.gov (NCT00552357).

Abstract
BACKGROUND Existing measures of frailty developed in community dwelling older adults may misclassify frailty in lung transplant candidates. We aimed to develop a novel frailty scale for lung transplantation with improved performance characteristics. METHODS We measured the short physical performance battery (SPPB), fried frailty phenotype (FFP), Body Composition, and serum Biomarkers representative of putative frailty mechanisms. We applied a 4-step established approach (identify frailty domain variable bivariate associations with the outcome of waitlist delisting or death; build models sequentially incorporating variables from each frailty domain cluster; retain variables that improved model performance ability by c-statistic or AIC) to develop 3 candidate "Lung Transplant Frailty Scale (LT-FS)" measures: 1 incorporating readily available clinical data; 1 adding muscle mass, and 1 adding muscle mass and research-grade Biomarkers. We compared construct and predictive validity of LT-FS models to the SPPB and FFP by ANOVA, ANCOVA, and Cox proportional-hazard modeling. RESULTS In 342 lung transplant candidates, LT-FS models exhibited superior construct and predictive validity compared to the SPPB and FFP. The addition of muscle mass and Biomarkers improved model performance. Frailty by all measures was associated with waitlist disability, poorer HRQL, and waitlist delisting/death. LT-FS models exhibited stronger associations with waitlist delisting/death than SPPB or FFP (C-statistic range: 0.73-0.78 vs. 0.57 and 0.55 for SPPB and FFP, respectively). Compared to SPPB and FFP, LT-FS models were generally more strongly associated with delisting/death and improved delisting/death net reclassification, with greater improvements with increasing LT-FS model complexity (range: 0.11-0.34). For example, LT-FS-Body Composition hazard ratio for delisting/death: 6.0 (95%CI: 2.5, 14.2), SPPB HR: 2.5 (95%CI: 1.1, 5.8), FFP HR: 4.3 (95%CI: 1.8, 10.1). Pre-transplant LT-FS frailty, but not SPPB or FFP, was associated with mortality after transplant. CONCLUSIONS The LT-FS is a disease-specific physical frailty measure with face and construct validity that has superior predictive validity over established measures.

Abstract
Background Tacrolimus therapy is standard of care for immunosuppression after lung transplantation. However, tacrolimus exposure variability during the early postoperative period may contribute to poor outcomes in this population. Few studies have examined tacrolimus pharmacokinetics (PK) during this high-risk time period. Methods We conducted a retrospective pharmacokinetic study in lung transplant recipients at the University of Pennsylvania who were enrolled in the Lung Transplant Outcomes Group (LTOG) cohort. We derived a model in 270 patients using NONMEM (version 7.5.1) and examined validity in a separate cohort of 114 patients. Covariates were examined with univariate analysis and multivariable analysis was developed using forward and backward stepwise selection. Performance of the final model in the validation cohort was examined with calculation of mean prediction error (PE). Results We developed a one-compartment base model with a fixed rate absorption constant. Significant covariates in multivariable analysis were postoperative day, hematocrit, transplant type, CYP3A5 genotype, total body weight, and time-varying postoperative day, hematocrit, and CYP inhibitor drugs. The strongest predictor of tacrolimus clearance was postoperative day, with median predicted clearance increasing more than threefold over the 14 day study period. In the validation cohort, the final model showed a mean PE of 36.4% (95%CI 30.8%-41.9%) and a median PE of 7.2% (IQR -29.3%-70.53%). Conclusion Postoperative day was the strongest predictor of tacrolimus exposure in the early post-lung transplant period. Future multicenter studies employing intensive sampling to examine a broad set of variables related to critical illness physiology are needed to understand determinants of clearance, volume of distribution and absorption in this population.

Abstract
Rationale: Low and high body mass index (BMI) are associated with increased mortality after lung transplantation. Why extremes of BMI might increase risk of death is unknown. Objectives: To estimate the association of extremes of BMI with causes of death after transplantation. Methods: We performed a retrospective study of the United Network for Organ Sharing database, including 26,721 adults who underwent lung transplantation in the United States between May 4, 2005, and December 2, 2020. We mapped 76 reported causes of death into 16 distinct groups. We estimated cause-specific hazards for death from each cause using Cox models. Results: Relative to a subject with a BMI of 24 kg/m2, a subject with a BMI of 16 kg/m2 had 38% (hazard ratio [HR], 1.38; 95% confidence interval [95% CI], 0.99-1.90), 82% (HR, 1.82; 95% CI, 1.34-2.46), and 62% (HR, 1.62; 95% CI, 1.18-2.22) increased hazards of death from acute respiratory failure, chronic lung allograft dysfunction (CLAD), and infection, respectively, and a subject with a BMI of 36 kg/m2 had 44% (HR, 1.44; 95% CI, 0.97-2.12), 42% (HR, 1.42; 95% CI, 0.93-2.15), and 185% (HR, 2.85; 95% CI, 1.28-6.33) increased hazards of death from acute respiratory failure, CLAD, and primary graft dysfunction, respectively. Conclusions: Low BMI is associated with increased risk of death from infection, acute respiratory failure, and CLAD after lung transplantation, whereas high BMI is associated with increased risk of death from primary graft dysfunction, acute respiratory failure, and CLAD.

Abstract
Heterogeneous frailty pathobiology might explain the inconsistent associations observed between frailty and lung transplant outcomes. A Subphenotype analysis could refine frailty measurement. In a 3-center pilot cohort study, we measured frailty by the Short Physical Performance Battery, body composition, and serum biomarkers reflecting causes of frailty. We applied latent class modeling for these baseline data. Next, we tested class construct validity with disability, waitlist delisting/death, and early postoperative complications. Among 422 lung transplant candidates, 2 class model fit the best (P = .01). Compared with Subphenotype 1 (n = 333), Subphenotype 2 (n = 89) was characterized by systemic and innate inflammation (higher IL-6, CRP, PTX3, TNF-R1, and IL-1RA); mitochondrial stress (higher GDF-15 and FGF-21); sarcopenia; malnutrition; and lower hemoglobin and walk distance. Subphenotype 2 had a worse disability and higher risk of waitlist delisting or death (hazards ratio: 4.0; 95% confidence interval: 1.8-9.1). Of the total cohort, 257 underwent transplant (Subphenotype 1: 196; Subphenotype 2: 61). Subphenotype 2 had a higher need for take back to the operating room (48% vs 28%; P = .005) and longer posttransplant hospital length of stay (21 days [interquartile range: 14-33] vs 18 days [14-28]; P = .04). Subphenotype 2 trended toward fewer ventilator-free days, needing more postoperative extracorporeal membrane oxygenation and dialysis, and higher need for discharge to rehabilitation facilities (P ≤ .20). In this early phase study, we identified biological frailty Subphenotypes in lung transplant candidates. A hyperinflammatory, sarcopenic Subphenotype seems to be associated with worse clinical outcomes.

Abstract
BACKGROUND Previous studies have reported similarities in long-term outcomes following lung transplantation for connective tissue disease-associated interstitial lung disease (CTD-ILD) and idiopathic pulmonary fibrosis (IPF). However, it is unknown whether CTD-ILD patients are at increased risk of primary graft dysfunction (PGD), delays in extubation, or longer index hospitalizations following transplant compared to IPF patients. METHODS We performed a multicenter retrospective cohort study of CTD-ILD and IPF patients enrolled in the Lung Transplant Outcomes Group registry who underwent lung transplantation between 2012 and 2018. We utilized mixed effects logistic regression and stratified Cox proportional hazards regression to determine whether CTD-ILD was independently associated with increased risk for grade 3 PGD or delays in post-transplant extubation and hospital discharge compared to IPF. RESULTS A total of 32.7% (33/101) of patients with CTD-ILD and 28.9% (145/501) of patients with IPF developed grade 3 PGD 48-72 hours after transplant. There were no significant differences in odds of grade 3 PGD among patients with CTD-ILD compared to those with IPF (adjusted OR 1.12, 95% CI 0.64-1.97, p = 0.69), nor was CTD-ILD independently associated with a longer post-transplant time to extubation (adjusted HR for first extubation 0.87, 95% CI 0.66-1.13, p = 0.30). However, CTD-ILD was independently associated with a longer post-transplant hospital length of stay (median 23 days [IQR 14-35 days] vs17 days [IQR 12-28 days], adjusted HR for hospital discharge 0.68, 95% CI 0.51-0.90, p = 0.008). CONCLUSION Patients with CTD-ILD experienced significantly longer postoperative hospitalizations compared to IPF patients without an increased risk of grade 3 PGD.

Abstract
BACKGROUND The complement system plays a key role in host defense but is activated by ischemia/reperfusion injury (IRI). Primary graft dysfunction (PGD) is a form of acute lung injury occurring predominantly due to IRI, which worsens survival after lung transplantation (LTx). Local complement activation is associated with acute lung injury, but whether it is more reflective of allograft injury compared with systemic activation remains unclear. We proposed that local complement activation would help identify those who develop PGD after LTx. We also aimed to identify which complement activation pathways are associated with PGD. METHODS We performed a multicenter cohort study at the University of Pennsylvania and Washington University School of Medicine. Bronchoalveolar lavage (BAL) and plasma specimens were obtained from recipients within 24 hours after LTx. PGD was scored based on the consensus definition. Complement activation products and components of each arm of the complement cascade were measured using ELISA. RESULTS In both cohorts, sC4d and sC5b-9 levels were increased in BAL of subjects with PGD compared with those without PGD. Subjects with PGD also had higher C1q, C2, C4, and C4b, compared with subjects without PGD, suggesting classical and lectin pathway involvement. Ba levels were higher in subjects with PGD, suggesting alternative pathway activation. Among lectin pathway–specific components, MBL and FCN-3 had a moderate-to-strong correlation with the terminal complement complex in the BAL but not in the plasma. CONCLUSION Complement activation fragments are detected in the BAL within 24 hours after LTx. Components of all 3 pathways are locally increased in subjects with PGD. Our findings create a precedent for investigating complement-targeted therapeutics to mitigate PGD. FUNDING This research was supported by the NIH, American Lung Association, Children’s Discovery Institute, Robert Wood Johnson Foundation, Cystic Fibrosis Foundation, Barnes-Jewish Hospital Foundation, Danish Heart Foundation, Danish Research Foundation of Independent Research, Svend Andersen Research Foundation, and Novo Nordisk Research Foundation. Substantial differences between local and systemic complement activation in lung transplant recipients who develop primary graft dysfunction are identified in two independent cohorts.

Abstract
Tacrolimus exhibits unpredictable pharmacokinetics (PKs) after lung transplant, partly explained by cytochrome P450 (CYP)-enzyme polymorphisms. However, whether exposure variability during the immediate postoperative period affects outcomes is unknown, and pharmacogenetic dosing may be limited by residual PK variability. We estimated adjusted associations between early postoperative tacrolimus concentrations and acute kidney injury (AKI) and acute cellular rejection (ACR), and identified clinical and pharmacogenetic factors that explain postoperative tacrolimus concentration variability in 484 lung transplant patients. Increasing tacrolimus concentration was associated with higher AKI risk (hazard ratio (HR) 1.54; 95% confidence interval (CI) 1.20-1.96 per 5-mg/dL); and increasing AKI severity (odds ratio 1.29; 95% CI 1.04-1.60 per 5-mg/dL), but not ACR (HR 1.02; 95% CI 0.73-1.42). A model with clinical and pharmacogenetic factors explained 42% of concentration variance compared with 19% for pharmacogenetic factors only. Early tacrolimus exposure was independently associated with AKI after lung transplantation, but not ACR. Clinical factors accounted for substantial residual tacrolimus concentration variability not explained by CYP-enzyme polymorphisms.

Abstract
Frailty is associated with increased mortality among lung transplant candidates. We sought to determine the association between frailty, as measured by the Short Physical Performance Battery (SPPB), and mortality after lung transplantation. In a multicenter prospective cohort study of adults who underwent lung transplantation, preoperative frailty was assessed with the SPPB (n = 318) and, in a secondary analysis, the Fried Frailty Phenotype (FFP; n = 299). We tested the association between preoperative frailty and mortality following lung transplantation with propensity score-adjusted Cox models. We calculated postestimation marginalized standardized risks for 1-year mortality by frailty status using multivariate logistic regression. SPPB frailty was associated with an increased risk of both 1- and 4-year mortality (adjusted hazard ratio [aHR]: 7.5; 95% confidence interval [CI]: 1.6-36.0 and aHR 3.8; 95%CI: 1.8-8.0, respectively). Each 1-point worsening in SPPB was associated with a 20% increased risk of death (aHR: 1.20; 95%CI: 1.08-1.33). Frail subjects had an absolute increased risk of death within the first year after transplantation of 12.2% (95%CI: 3.1%-21%). In secondary analyses, FFP frailty was associated with increased risk of death within the first postoperative year (aHR: 3.8; 95%CI: 1.1-13.2) but not over longer follow-up. Preoperative frailty is associated with an increased risk of death after lung transplantation.

Abstract
BACKGROUND Delirium significantly affects post-operative outcomes, but the incidence, risk factors, and long-term impact of delirium in lung transplant recipients have not been well studied. METHODS We analyzed 155 lung transplant recipients enrolled in the Lung Transplant Outcomes Group (LTOG) cohort at a single center. We determined delirium incidence by structured chart review, identified risk factors for delirium, determined whether plasma concentrations of 2 cerebral injury markers (neuron-specific enolase [NSE] and glial fibrillary acidic protein [GFAP]) were associated with delirium, and determined the association of post-operative delirium with 1-year survival. RESULTS Fifty-seven (36.8%) patients developed post-operative delirium. Independent risk factors for delirium included pre-transplant benzodiazepine prescription (relative risk [RR] 1.82; 95% confidence interval [CI] 1.08 to 3.07; p = 0.025), total ischemic time (RR 1.10 per 30-minute increase; 95% CI 1.01 to 1.21; p = 0.027), duration of time with intra-operative mean arterial pressure <60 mm Hg (RR 1.07 per 15-minute increase; 95% CI 1.00 to 1.14; p = 0.041), and Grade 3 primary graft dysfunction (RR 2.13; 95% CI 1.27 to 3.58; p = 0.004). Ninety-one (58.7%) patients had plasma available at 24 hours. Plasma GFAP was inconsistently detected, whereas NSE was universally detectable, with higher NSE concentrations associated with delirium (risk difference 15.1% comparing 75th and 25th percentiles; 95% CI 2.5 to 27.7; p = 0.026). One-year mortality appeared higher among delirious patients, 12.3% compared with 7.1%, but the difference was not significant (p = 0.28). CONCLUSIONS Post-operative delirium is common in lung transplant recipients, and several potentially modifiable risk factors deserve further study to determine their associated mechanisms and predictive values.

Abstract
Chlamydia trachomatis, an important cause of human disease, is an obligate intracellular bacterial pathogen that relies on the eukaryotic host cell for its replication. Recent reports have revealed that the C. trachomatis vacuole receives host-derived sphingolipids by fusing with trans-Golgi network (TGN)derived secretory vesicles. Here, it is shown that these lipids are required for the growth of the bacteria. C. trachomatis was unable to replicate at 39 degrees C in the Chinese hamster ovary (CHO)-derived cell line SPB-1, a cell line incapable of synthesizing sphingolipids at this temperature because of a temperature-sensitive mutation in the serine palmitoyltransferase (SPT) gene. Complementation with the wild-type SPT gene or addition of exogenous cell-permeable sphingolipid precursors to the mutant cells restored their ability to support chlamydial replication. L-cycloserine (L-CS) and fumonisin B1 (FB1), inhibitors of sphingolipid biosynthesis, decreased the proliferation of the bacteria in eukaryotic cells at concentrations that also decreased host cell sphingolipid synthesis. In the case of FB1, the vacuoles appeared aberrant; the addition of sphingolipid precursors was able to reverse the altered morphology of the FB1-treated vacuoles. Collectively, these data strongly suggest that the growth and replication of chlamydiae is dependent on synthesis of sphingolipids by the eukaryotic host cell and may contribute to this organism's obligate intracellular parasitism.

Abstract
PURPOSE To confirm the promising phase II results of docetaxel monotherapy, this phase III trial was conducted of chemotherapy for patients with advanced non-small-cell lung cancer (NSCLC) who had previously failed platinum-containing chemotherapy. PATIENTS AND METHODS A total of 373 patients were randomized to receive either docetaxel 100 mg/m(2) (D100) or 75 mg/m(2) (D75) versus a control regimen of vinorelbine or ifosfamide (V/I). The three treatment groups were well-balanced for key patient characteristics. RESULTS Overall response rates were 10.8% with D100 and 6.7% with D75, each significantly higher than the 0.8% response with V/I (P =.001 and P =.036, respectively). Patients who received docetaxel had a longer time to progression (P =.046, by log-rank test) and a greater progression-free survival at 26 weeks (P =.005, by chi(2) test). Although overall survival was not significantly different between the three groups, the 1-year survival was significantly greater with D75 than with the control treatment (32% v 19%; P =.025, by chi(2) test). Prior exposure to paclitaxel did not decrease the likelihood of response to docetaxel, nor did it impact survival. There was a trend toward greater efficacy in patients whose disease was platinum-resistant rather than platinum-refractory and in patients with performance status of 0 or 1 versus 2. Toxicity was greatest with D100, but the D75 arm was well-tolerated. CONCLUSION This first randomized trial in this setting demonstrates that D75 every 3 weeks can offer clinically meaningful benefit to patients with advanced NSCLC whose disease has relapsed or progressed after platinum-based chemotherapy.

Abstract
PURPOSE To evaluate the feasibility, toxicity, and efficacy of adding vinorelbine to the paclitaxel/carboplatin combination in the treatment of advanced non-small cell lung cancer. PATIENTS AND METHODS Patients with advanced (stage IIIB/IV) non-small cell lung cancer who had received no previous chemotherapy were treated with the following three-drug regimen: paclitaxel, 200 mg/m2, 1-hour i.v. infusion, day 1; carboplatin, AUC 6.0 i.v., day 1; and vinorelbine, 22.5 mg/m2 i.v. days 1 and either 8 or 15. Treatment was repeated every 21 days. This phase II trial was conducted in a multicenter, community-based setting. RESULTS Eighty-nine patients were treated with a median of four courses of therapy (range, one to eight). Thirty-one patients (35%) had major responses (two complete, 29 partial), and 36 patients (40%) had a minor response or stable disease. Actuarial median survival was 8.6 months; 1 year survival was 43%. Leukopenia was the major toxicity: 73% of patients had grade 3/4 toxicity, and 32 patients (36%) were hospitalized for neutropenia/fever (11% of total courses administered). Treatment-related death due to infection occurred in four patients (4%). CONCLUSIONS This three-drug regimen is feasible and efficacious in the treatment of advanced non-small cell lung cancer. The addition of vinorelbine increases the incidence of severe leukopenia substantially when compared with the paclitaxel/carboplatin regimen. However, other toxicities are not markedly increased. Ongoing randomized trials will define the role of this regimen in the treatment of non-small cell lung cancer.

Abstract
The purpose of this trial was to determine the effects of paclitaxel in patients with newly diagnosed metastatic breast cancer scheduled to receive high-dose chemotherapy with peripheral blood stem cell support. Eighty-four patients received anthracycline-based induction and two doses of paclitaxel at 170 mg/m2 (n = 52) or 250 mg/m2 (n = 32). Eighty-two (98%) received cyclophosphamide and etoposide (n = 50) or paclitaxel and cyclophosphamide (n = 32) with granulocyte colony-stimulating factor for mobilization of peripheral blood stem cells, and 79 (94%) received cyclophosphamide, thiotepa, and carboplatin with peripheral blood stem cell support. One patient (1%) died of infection and 56 (67%) died of progressive disease. For patients with measurable disease, the complete response rate was 21% after induction and 29% after paclitaxel (p = 0.54). Results were compared with those of 125 patients who received the same sequence of therapy without paclitaxel. The complete response rate after high-dose chemotherapy was 54% for patients receiving paclitaxel and 62% for those not receiving paclitaxel (p = 0.60). The probabilities of overall survival and event-free survival at 3 years for patients receiving paclitaxel were 46% and 24%, respectively, compared with 54% and 22%, respectively, for patients not receiving paclitaxel (p = 0.62). Further trials evaluating this dose and schedule of paclitaxel in patients with metastatic breast cancer receiving high-dose chemotherapy are not warranted.

Abstract
PURPOSE For patients receiving chemotherapy, optimization of antiemetic therapy in terms of safety of administration, efficacy, cost, and convenience remains a subject of intense clinical research. In this study, we evaluated and compared the safety and antiemetic efficacy of a single 30-second intravenous bolus infusion of granisetron which those of a standard 15-minute intravenous infusion of ondansetron in chemotherapy-naive breast cancer patients receiving moderately emetogenic chemotherapy. PATIENTS AND MATERIALS This was a randomized, double-blind, double-dummy, multicenter crossover study of 623 chemotherapy-naive patients (two male, 621 female) receiving moderately emetogenic chemotherapy (cyclophosphamide plus doxorubicin, with or without 5-fluorouracil) for breast cancer. Patients were assigned randomly to receive either granisetron or ondansetron in cycle 1 and the other agent in cycle 2. Granisetron (10 micrograms/kg) was administered as a 30-second intravenous bolus infusion within 5 minutes before the start of chemotherapy, and ondansetron (32 mg) was administered as a 15-minute intravenous infusion beginning 30 minutes before the start of chemotherapy. A total of 573 patients received the two planned chemotherapy cycles. Safety assessment was based on the type and frequency of adverse experiences reported by the patient at 24 and 48 hours after chemotherapy began. Efficacy assessments included the occurrence of nausea or emesis and the proportion of patients who achieved total emetic control at 24 and 48 hours after chemotherapy. RESULTS Similar proportions of patients in both treatment groups remained free of emesis at the 24-hour assessment period (58.6% and 62.7% of granisetron- and ondansetron-treated patients, respectively) and at 48 hours (42.2% and 45.0% for granisetron vs ondansetron) in both cycles. The proportions of granisetron- and ondansetron-treated patients who remained nausea-free for the first 24 hours after treatment in both cycles were 44.0% and 48.5%, respectively, and at 48 hours were 26.7% and 31.0%, respectively. Statistical analysis demonstrated no significant treatment-by-cycle interaction. The 30-second granisetron infusion and the 15-minute ondansetron infusion were well tolerated. However, administration of ondansetron as a 15-minute intravenous infusion produced abnormal vision (6.28%) in significantly more patients than granisetron (0.35%). DISCUSSION These two intravenous 5-hydroxytryptamine3-receptor antagonist antiemetics were similarly effective in controlling acute nausea and emesis during two cycles of moderately emetogenic chemotherapy. Granisetron (30 seconds) and the longer infusion of ondansetron (15 minutes) were well tolerated; however, ondansetron was associated with a greater proportion of patients reporting abnormal vision. Granisetron administered as a 30-second bolus infusion allows a considerably shorter waiting time between the end of the antiemetic infusion and the initiation of chemotherapy. This shorter administration time may enhance patient convenience and provider efficiency.

Abstract
We investigated the outcomes of patients with breast cancer undergoing induction chemotherapy, mobilization of peripheral blood stem cells (PBSC) and high-dose chemotherapy (HDC) with PBSC infusion. One hundred and fourteen patients with untreated stage IV breast cancer, with a median age of 46 years (range 24-62), were entered on a phase II trial consisting of; (1) doxorubicin, 5-flurouracil, methotrexate (AFM) x 4 courses at 2 week intervals; (2) cyclophosphamide (4 g/m2), etoposide (600 mg/m2), cisplatin (105 mg/m2) (CEP), filgrastim (6 micrograms/kg/day) and PBSC collection; (3) cyclophosphamide (6 g/m2), thiotepa (500 mg/m2), carboplatin (800 mg/m2), (CTCb) followed by PBSC infusion. All patients received AFM, 107 (94%) received CEP, 93 (82%) received CTCb and PBSC as per protocol and 99 (87%) ultimately received HDC and PBSC. There was one infectious death after AFM and all other deaths were associated with progressive disease. Fifty-two patients (46%) are alive, 21 (18%) without progression, at a median 31 months (range 22-47). The probabilities of survival and progression-free survival at 3.5 years were 0.40 and 0.17, respectively. All 62 patients with visceral disease and/or a prior history of doxorubicin adjuvant therapy have relapsed or progressed. We conclude that the sequential administration of AFM, CEP and CTCb followed by PBSC resulted in long-term PFS only in patients who were NED, had bone-only disease or had lymph node or soft tissue disease with or without bone disease. Other strategies, aimed at improving responses to initial therapy, improving HDC regimens and/or developing immunomodulatory therapies, will be necessary to improve PFS for patients who fail doxorubicin adjuvant or who have visceral disease.

Abstract
A phase-II trial of the second-generation platinum analog 1,2-diaminocyclohexane (4-carboxyphthalato) platinum (II) (DACCP) was performed in 33 patients with non-small cell lung cancer. The compound was studied because of its lack of cross resistance in vitro and decreased nephrotoxicity in both preclinical testing and in a phase-I trial. The starting dose was 640 mg/m2 IV every 3 weeks, with escalations to 720 mg/m2 in the absence of toxicity. Myelosuppression and nephrotoxicity were uncommon. Allergic reactions and neurotoxicity were seen in five and three patients, respectively. Of 28 patients evaluable for response, one partial remission of 3 months' duration was noted in a patient who had previously responded but subsequently progressed during cisplatin and vindesine medication. No responses were seen in 11 adequately treated patients who had received no prior therapy. DACCP has only minimal activity in non-small cell lung cancer. No further studies are planned in this disease.
