Abstract
BACKGROUND Normative infant body composition data using air displacement plethysmography (ADP) are from primarily Caucasian populations. Racial differences may exist. OBJECTIVES To describe body composition in Asian and Pacific Islander infants and compare them to previously published data on Caucasian infants. DESIGN Body composition was measured using ADP with the PEA POD® Infant Body Composition System in 249 healthy full-term newborns in a predominately Asian and Pacific Islander population in Hawaii within the first 3 days of life and compared to published data on Caucasian infants with multiple t-tests adjusted for false discovery rate. RESULTS There were no differences in percent body fat between Asian, Pacific Islander, or mixed race Asian Pacific Islander infants. Both Asian and Pacific Islander infants had significantly higher percent body fat than Caucasians from Italy in Europe (13.2% and 11.8% vs 8.9%, p < 0.01 among males, 15.3% and 15.6% vs 8.7%, p < 0.01 among females) but not when compared to Caucasians from New York. CONCLUSIONS Racial and geographical differences in body composition exist at birth between Asian and Pacific Islanders and other Caucasian cohorts. Previously published ADP nomograms must be interpreted with caution. Future studies are needed to investigate the impact of environmental, perinatal, and genetic factors on infant body composition and its relationship to future cardiometabolic morbidity. Efforts to address racial disparities in cardiometabolic disease measures must also address pre-conceptual maternal health, which may have long-term implications on future body composition in offspring.

Abstract
Importance The long-term effects of surfactant administration via a thin catheter (minimally invasive surfactant therapy [MIST]) in preterm infants with respiratory distress syndrome remain to be definitively clarified. Objective To examine the effect of MIST on death or neurodevelopmental disability (NDD) at 2 years' corrected age. Design, Setting, and Participants Follow-up study of a randomized clinical trial with blinding of clinicians and outcome assessors conducted in 33 tertiary-level neonatal intensive care units in 11 countries. The trial included 486 infants with a gestational age of 25 to 28 weeks supported with continuous positive airway pressure (CPAP). Collection of follow-up data at 2 years' corrected age was completed on December 9, 2022. Interventions Infants assigned to MIST (n = 242) received exogenous surfactant (200 mg/kg poractant alfa) via a thin catheter; those assigned to the control group (n = 244) received sham treatment. Main Outcomes and Measures The key secondary outcome of death or moderate to severe NDD was assessed at 2 years' corrected age. Other secondary outcomes included components of this composite outcome, as well as hospitalizations for respiratory illness and parent-reported wheezing or breathing difficulty in the first 2 years. Results Among the 486 infants randomized, 453 had follow-up data available (median gestation, 27.3 weeks; 228 females [50.3%]); data on the key secondary outcome were available in 434 infants. Death or NDD occurred in 78 infants (36.3%) in the MIST group and 79 (36.1%) in the control group (risk difference, 0% [95% CI, -7.6% to 7.7%]; relative risk [RR], 1.0 [95% CI, 0.81-1.24]); components of this outcome did not differ significantly between groups. Secondary respiratory outcomes favored the MIST group. Hospitalization with respiratory illness occurred in 49 infants (25.1%) in the MIST group vs 78 (38.2%) in the control group (RR, 0.66 [95% CI, 0.54-0.81]) and parent-reported wheezing or breathing difficulty in 73 (40.6%) vs 104 (53.6%), respectively (RR, 0.76 [95% CI, 0.63-0.90]). Conclusions and Relevance In this follow-up study of a randomized clinical trial of preterm infants with respiratory distress syndrome supported with CPAP, MIST compared with sham treatment did not reduce the incidence of death or NDD by 2 years of age. However, infants who received MIST had lower rates of adverse respiratory outcomes during their first 2 years of life. Trial Registration anzctr.org.au Identifier: ACTRN12611000916943.

Abstract
INTRODUCTION As planned home births increase, emerging evidence on the perinatal outcomes of newborns who were planned hospital births versus planned home births has been inconsistent, and a growing number of states have attempted to legislate community births. We sought to determine whether an association exists between neonatal hypoxic ischemic encephalopathy (HIE), a complication of ischemic birth injury, and planned location of birth. METHODS A case-control study design was used to compare data from neonates with HIE obtained from electronic health records at Kapiolani Medical Center for Women and Children in Honolulu, Hawaii, with data from neonates without HIE obtained from Hawaii state birth certificate data. A penalized backward stepwise logistic regression was performed to control for confounders. RESULTS We included 164 neonates with HIE and 656 neonates in the control group. The odds of having been a planned home birth were 2.77 times higher in neonates with HIE compared with those without HIE (95% CI, 1.05-6.87). After adjusting for insurance, mode of birth, meconium fluid, maternal hypertension, and chorioamnionitis, neonates with HIE were still more likely to have been a planned home birth compared with those without HIE (odds ratio, 11.56; 95% CI, 1.37-118.77). DISCUSSION Neonates with HIE were more likely to have been a planned home birth compared with neonates without HIE.

Abstract
IMPORTANCE The benefits of surfactant administration via a thin catheter (minimally invasive surfactant therapy [MIST]) in preterm infants with respiratory distress syndrome are uncertain. OBJECTIVE To examine the effect of selective application of MIST at a low fraction of inspired oxygen threshold on survival without bronchopulmonary dysplasia (BPD). DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial including 485 preterm infants with a gestational age of 25 to 28 weeks who were supported with continuous positive airway pressure (CPAP) and required a fraction of inspired oxygen of 0.30 or greater within 6 hours of birth. The trial was conducted at 33 tertiary-level neonatal intensive care units around the world, with blinding of the clinicians and outcome assessors. Enrollment took place between December 16, 2011, and March 26, 2020; follow-up was completed on December 2, 2020. INTERVENTIONS Infants were randomized to the MIST group (n = 241) and received exogenous surfactant (200 mg/kg of poractant alfa) via a thin catheter or to the control group (n = 244) and received a sham (control) treatment; CPAP was continued thereafter in both groups unless specified intubation criteria were met. MAIN OUTCOMES AND MEASURES The primary outcome was the composite of death or physiological BPD assessed at 36 weeks' postmenstrual age. The components of the primary outcome (death prior to 36 weeks' postmenstrual age and BPD at 36 weeks' postmenstrual age) also were considered separately. RESULTS Among the 485 infants randomized (median gestational age, 27.3 weeks; 241 [49.7%] female), all completed follow-up. Death or BPD occurred in 105 infants (43.6%) in the MIST group and 121 (49.6%) in the control group (risk difference [RD], -6.3% [95% CI, -14.2% to 1.6%]; relative risk [RR], 0.87 [95% CI, 0.74 to 1.03]; P = .10). Incidence of death before 36 weeks' postmenstrual age did not differ significantly between groups (24 [10.0%] in MIST vs 19 [7.8%] in control; RD, 2.1% [95% CI, -3.6% to 7.8%]; RR, 1.27 [95% CI, 0.63 to 2.57]; P = .51), but incidence of BPD in survivors to 36 weeks' postmenstrual age was lower in the MIST group (81/217 [37.3%] vs 102/225 [45.3%] in the control group; RD, -7.8% [95% CI, -14.9% to -0.7%]; RR, 0.83 [95% CI, 0.70 to 0.98]; P = .03). Serious adverse events occurred in 10.3% of infants in the MIST group and 11.1% in the control group. CONCLUSIONS AND RELEVANCE Among preterm infants with respiratory distress syndrome supported with CPAP, minimally invasive surfactant therapy compared with sham (control) treatment did not significantly reduce the incidence of the composite outcome of death or bronchopulmonary dysplasia at 36 weeks' postmenstrual age. However, given the statistical uncertainty reflected in the 95% CI, a clinically important effect cannot be excluded. TRIAL REGISTRATION anzctr.org.au Identifier: ACTRN12611000916943.

Abstract
Pathological (ectopic) mineralization of soft tissues occurs during aging, in several common conditions such as diabetes, hypercholesterolemia, and renal failure and in certain genetic disorders. Pseudoxanthoma elasticum (PXE), a multi-organ disease affecting dermal, ocular, and cardiovascular tissues, is a model for ectopic mineralization disorders. ABCC6 dysfunction is the primary cause of PXE, but also some cases of generalized arterial calcification of infancy (GACI). ABCC6 deficiency in mice underlies an inducible dystrophic cardiac calcification phenotype (DCC). These calcification diseases are part of a spectrum of mineralization disorders that also includes Calcification of Joints and Arteries (CALJA). Since the identification of ABCC6 as the “PXE gene” and the development of several animal models (mice, rat, and zebrafish), there has been significant progress in our understanding of the molecular genetics, the clinical phenotypes, and pathogenesis of these diseases, which share similarities with more common conditions with abnormal calcification. ABCC6 facilitates the cellular efflux of ATP, which is rapidly converted into inorganic pyrophosphate (PPi) and adenosine by the ectonucleotidases NPP1 and CD73 (NT5E). PPi is a potent endogenous inhibitor of calcification, whereas adenosine indirectly contributes to calcification inhibition by suppressing the synthesis of tissue non-specific alkaline phosphatase (TNAP). At present, therapies only exist to alleviate symptoms for both PXE and GACI; however, extensive studies have resulted in several novel approaches to treating PXE and GACI. This review seeks to summarize the role of ABCC6 in ectopic calcification in PXE and other calcification disorders, and discuss therapeutic strategies targeting various proteins in the pathway (ABCC6, NPP1, and TNAP) and direct inhibition of calcification via supplementation by various compounds.

Abstract
ABCC6 deficiency promotes ectopic calcification; however, circumstantial evidence suggested that ABCC6 may also influence atherosclerosis. The present study addressed the role of ABCC6 in atherosclerosis using Ldlr-/- mice and pseudoxanthoma elasticum (PXE) patients. Mice lacking the Abcc6 and Ldlr genes were fed an atherogenic diet for 16 weeks before intimal calcification, aortic plaque formation and lipoprotein profile were evaluated. Cholesterol efflux and the expression of several inflammation, atherosclerosis and cholesterol homeostasis-related genes were also determined in murine liver and bone marrow-derived macrophages. Furthermore, we examined plasma lipoproteins, vascular calcification, carotid intima-media thickness and atherosclerosis in a cohort of PXE patients with ABCC6 mutations and compared results to dysmetabolic subjects with increased cardiovascular risk. We found that ABCC6 deficiency causes changes in lipoproteins, with decreased HDL cholesterol in both mice and humans, and induces atherosclerosis. However, we found that the absence of ABCC6 does not influence overall vascular mineralization induced with atherosclerosis. Decreased cholesterol efflux from macrophage cells and other molecular changes such as increased pro-inflammation seen in both humans and mice are likely contributors for the phenotype. However, it is likely that other cellular and/or molecular mechanisms are involved. Our study showed a novel physiological role for ABCC6, influencing plasma lipoproteins and atherosclerosis in a haploinsufficient manner, with significant penetrance.

Abstract
Pseudoxanthoma elasticum is a heritable disease caused by ABCC6 deficiency. Patients develop ectopic calcification in skin, eyes, and vascular tissues. ABCC6, primarily found in liver and kidneys, mediates the cellular efflux of ATP, which is rapidly converted into inorganic pyrophosphate (PPi), a potent inhibitor of calcification. Pseudoxanthoma elasticum patients and Abcc6-/- mice display reduced PPi levels in plasma and peripheral tissues. Pseudoxanthoma elasticum is currently incurable, although some palliative treatments exist. In recent years, we have successfully developed therapeutic methodologies to compensate the PPi deficit in animal models and humans. Here, we inadvertently discovered that modulating dietary PPi can also be an effective approach to reducing calcification in Abcc6-/- mice. Our findings were prompted by a change in institutional rodent diet. The new chow was enriched in PPi, which increased plasma PPi, and significantly reduced mineralization in Abcc6-/- mice. We also found that dietary PPi is readily absorbed in humans. Our results suggest that the consumption of food naturally or artificially enriched in PPi represents a possible intervention to mitigate calcification progression in pseudoxanthoma elasticum, that dietary preferences of patients may explain pseudoxanthoma elasticum heterogeneous manifestations, and that animal chow has the potential to influence data reproducibility.

Abstract
BACKGROUND AND OBJECTIVE Central venous catheters in the NICU are associated with significant morbidity and mortality because of the risk of central line-associated bloodstream infections (CLABSIs). The purpose of this study was to determine the effect of catheter dwell time on risk of CLABSI. METHODS Retrospective cohort study of 13,327 infants with 15,567 catheters (93% peripherally inserted central catheters [PICCs], 7% tunneled catheters) and 256,088 catheter days cared for in 141 NICUs. CLABSI was defined using National Health Surveillance Network criteria. We defined dwell time as the number of days from line insertion until either line removal or day of CLABSI. We generated survival curves for each week of dwell time and estimated hazard ratios for CLABSI at each week by using a Cox proportional hazards frailty model. We controlled for postmenstrual age and year, included facility as a random effect, and generated separate models by line type. RESULTS Median postmenstrual age was 29 weeks (interquartile range 26-33). The overall incidence of CLABSI was 0.93 per 1000 catheter days. Increased dwell time was not associated with increased risk of CLABSI for PICCs. For tunneled catheters, infection incidence was significantly higher in weeks 7 and 9 compared with week 1. CONCLUSIONS Clinicians should not routinely replace uninfected PICCs for fear of infection but should consider removing tunneled catheters before week 7 if no longer needed. Additional studies are needed to determine what daily maintenance practices may be associated with decreased risk of infection, especially for tunneled catheters.

Abstract
Previously, we demonstrated that Propionibacterium acnes, a human skin commensal bacterium, ferments glycerol into short-chain fatty acids, including propionic acid. Propionic acid suppressed the growth of Staphylococcus aureus USA300, a community-acquired methicillin-resistant bacterium, in vitro and in vivo. In this study, it is demonstrated that the anti-USA300 activity of propionic acid persisted after buffering the acid with 4-(2-hydroxyethyl)-1- piperazineethanesulfonic acid. This suggests that the growth suppression of USA300 mainly resulted from the antimicrobial activity of propionic acid per se and not from the acidity of the medium. In addition, proprionic acid significantly reduced the intracellular pH of USA300 and exhibited broad-spectrum antimicrobial activity against Escherichia coli and Candida albicans. P. acnes showed a higher tolerance to propionic acid. Next, an esterified derivative of propionic acid was synthesised. Propionic acid and the esterified derivative were equivalent in their efficacy to suppress the growth of USA300 in vitro. The esterified derivative thus provides an alternative to propionic acid as an antimicrobial agent against S. aureus.

Abstract
Real-time (RT) determination of the health of in vitro tissue-engineered constructs prior to grafting is essential for prediction of success of the implanted tissue-engineered graft. In addition, the US Food and Drug Administration requires specific release criteria in RT prior to the release of tissue-engineered devices for human use. In principle, assessing the viability and functionality of the cellular component can be achieved by quantifying the secretion of growth factors and chemokines of tissue-engineered constructs. Ex vivo-produced oral mucosa equivalents (EVPOMEs) were fabricated under thermally stressed conditions at 43 °C for 24 h to create a functionally compromised EVPOME. We used microchannel enzyme-linked immunosorbent assay to evaluate the functionality of the cellular component, oral keratinocytes, of stressed and unstressed EVPOMEs by measuring the release of vascular endothelial growth factor (VEGF), interleukin-8 (IL-8), human β-defensin 1 (hBD-1), and tissue inhibitor of metalloproteinase 1 and 2 (TIMP-1 and -2) into the spent medium, which was collected on the same day prior to graft implantation into severe combined immunodeficiency mice. Implanted EVPOMEs' histology on the seventh postimplantation day was used to correlate outcomes of grafting to secreted amounts of IL-8, hBD-1, VEGF, TIMP-1, and TIMP-2 from corresponding EVPOMEs. Our findings showed that significantly higher levels of IL-8, hBD-1, and TIMP-2 were secreted from controls than from thermally stressed EVPOMEs. We also found a direct correlation between secreted VEGF and IL-8 and blood vessel counts of implanted EVPOMEs. We concluded that measuring the constitutive release of these factors can be used as noninvasive predictors of healthy tissue-engineered EVPOMEs in RT, prior to their implantation.

Abstract
Propionibacterium acnes (P. acnes), a Gram-positive anaerobic bacterium, is a commensal organism in human skin. Like human cells, the bacteria produce porphyrins, which exhibit fluorescence properties and make bacteria visible with a Wood's lamp. In this review, we compare the porphyrin biosynthesis in humans and P. acnes. Also, since P. acnes living on the surface of skin receive the same radiation exposure as humans, we envision that the changes in porphyrin profiles (the absorption spectra and/or metabolism) of P. acnes by radiation may mirror the response of human cells to radiation. The porphyrin profiles of P. acnes may be a more accurate reflection of radiation risk to the patient than other biodosimeters/biomarkers such as gene up-/down-regulation, which may be non-specific due to patient related factors such as autoimmune diseases. Lastly, we discuss the challenges and possible solutions for using the P. acnes response to predict the radiation risk.

Abstract
BACKGROUND Delivery of premature infants outside tertiary care centers is not always preventable. The aim of this study was to compare rates of survival and common morbidities in extremely premature babies transported to a level III facility versus those born at the level III center. METHODS Retrospective chart review was performed on all neonates born at ≤ 28 weeks of gestation with birthweight ≤ 1500 g who were admitted to the Newborn Intensive Care Unit at Kapi'olani Medical Center for Women and Children (KMCWC) between 1 January 2000 and 31 December 2005. Infants were divided into two groups, those born at KMCWC (Inborn) and those born at level I institutions and subsequently transported (Transport) to KMCWC. RESULTS A total of 394 neonates met the study criteria; 349 were inborn while 45 were transported. Survival rates were identical for both groups. However, the Transport group survivors displayed a significantly longer mean length of stay and higher rate of severe retinopathy of prematurity than those in the Inborn group (P ≤ 0.01). CONCLUSION Identical rates of survival in both groups suggest that community medical professionals are providing satisfactory care to stabilize critical neonates without reducing their chances of survival. However, increased length of stay and higher rate of retinopathy of prematurity in the Transport group suggest that differences in medical management during the first few hours of life may adversely affect outcomes.

Abstract
Osteonecrosis of the jaw (ONJ), a side-effect of bisphosphonate therapy, is characterized by exposed bone that fails to heal within eight weeks. Healing time of oral epithelial wounds is decreased in the presence of amino-bisphosphonates; however, the mechanism remains unknown. We examined human tissue from individuals with ONJ and non-bisphosphonate-treated control individuals to identify changes in oral epithelium and connective tissue. Oral and intravenous bisphosphonate-treated ONJ sites had reduced numbers of basal epithelial progenitor cells, as demonstrated by a 13.8±1.1% and 31.9±5.8% reduction of p63 expression, respectively. No significant differences in proliferation rates, vessel density, or macrophage number were noted. In vitro treatment of clonal and primary oral keratinocytes with zoledronic acid (ZA) inhibited p63, and expression was rescued by the addition of mevalonate pathway intermediates. In addition, both ZA treatment and p63 shRNA knock-down impaired formation of 3D Ex Vivo Produced Oral Mucosa Equivalents (EVPOME) and closure of an in vitro scratch assay. Analysis of our data suggests that bisphosphonate treatment may delay oral epithelial healing by interfering with p63-positive progenitor cells in the basal layer of the oral epithelium in a mevalonate-pathway-dependent manner. This delay in healing may increase the likelihood of osteonecrosis developing in already-compromised bone.

Abstract
e19512 Background: We have recently demonstrated that nuclear expression of BCL10 or NF-κB helps predict H. pylori-independent status; and inflammatory cytokines such as TNF-α may be related to BCL10 nuclear translocation (Blood 2005;106:1037–41;J Biol Chem 2006;281:167–75). Recent studies have been shown that the chimeric protein of t(11;18)(q21;q21) can lead to constitutive NF-κB activity and thereby mediate cell survival and anti-apoptotic signals. The present study was conducted to investigate the molecular mechanism and the clinical efficacy of thalidomide, an TNF-α or NF-κB inhibitor, in H. pylori-independent MALT lymphoma. Methods: Between October 2003 and June 2007, our study enrolled 11 H. pylori-independent MALT lymphoma patients ( 7 men and 4 women; age range, 43 to 79 years; 7 patients who had failed chemotherapy or rituximab) with nuclear expression of BCL10 or NF-κB in pretreatment lymphoma tissues treated at National Taiwan University Hospital with thalidomide 100mg to 200 mg oral given daily. The presence of t(11;18)(q21;q21) was identified by a multiplex reverse transcriptase polymerase chain reaction of the API2-MALT1 chimeric transcript. Results: Three (27.3%) of 11 patients achieved a complete response (CR), and 3 (27.3) of 11 patients achieved a partial response (PR), resulting in an overall response rate of 54.5% (95% CI, 19.5%-89.6%). The median time from thalidomide therapy to CR was 3.0 months (range, 2.7–4.9 months). At a median follow-up of 41.6 months (range, 17.7–63.8 months), the 3-year event-free survival and overall survival after thalidomide treatment was 80.8%, and 88.9%, respectively. The API2-MALT1 fusion transcript for t(11;18)(q21;q21) was detected in 1 (16.7%) of 6 patients with CR or PR, and 4 (80.0%) of 5 patients with stable or progressive disease (P = 0.08). Conclusions: Our results indicate that thalidomide can be an adjuvant treatment for H. pylori-independent MALT lymphoma patients. Additional investigation of the molecular mechanisms and biologic significance of the API2-MALT1 fusion transcript responsible for thalidomide resistance in this group of tumors is needed.

Abstract
This study examined the impregnation of hybrid poplar shavings with Fe or Al oxide and their reactivity with Cr(VI). The shavings were impregnated with an average of 1.24+/-0.18 mmol Fe g(-1) or 1.51+/-0.17 mmol Al g(-1), and the impregnated Fe or Al oxide was highly amorphous. Capacity of Cr(VI) sorption by impregnated shavings was high and rate of the sorption was rapid. While the freshly sorbed Cr on the Fe oxide-shavings was readily desorbed in 0.1M NaOH, nine weeks of ageing reduced the desorbability to only 6.5% of the sorbed Cr. Extraction with 0.1M NaOH remained feasible to recover most sorbed Cr from the Al oxide-shavings over the same ageing period. Impregnation of the shavings with Fe or Al oxide turns the wood waste into a product for removing Cr(VI) or other oxyanions from wastewater.

Abstract
18072 Background: Epirubicin is active for treatment of non-small cell lung carcinoma (NSCLC) but its optimal dose was undetermined. This study was designed to evaluate the efficacy and safety of gemcitabine plus conventional-dose epirubicin for stage IIIB/IV NSCLC. Methods: Patients with histological or cytological diagnosis of stage IIIB/IV NSCLC who had not received prior chemotherapy were eligible. Patients were randomized to GE (gemcitabine, 1,000 mg/m2 on days 1, 8, and 15 and epirubicin, 70 mg/m2 on day 15) or GC (gemcitabine, 1,000 mg/m2 on days 1, 8, and 15 and cisplatin, 80 mg/m2 on day 15). Treatment cycles were repeated every 4 weeks. Objective tumor response and toxicity were evaluated by using the World Health Organization criteria. Results: No significant difference in baseline characteristics between patients randomized to GC (n=41) and GE (n=39) arms were found. The objective response rate was 31.0% (95% C.I. 16.4% to 45.5) for GC and 37.2.0% (95% C.I. 22.2% to 52.3%) for GE. The median time-to-treatment-failure and overall survival were 6.1 months (95% C.I. 4.9 to 7.4 months) and 13.2 months (95% C.I. 8.9 to 17.5 months) for GC and 6.2 months (95% C.I. 5.2 to 7.2 months) and 21.2 months (95% C.I. 14.6 to 27.8 months) for GE, respectively. More grade 3/4 neutropenia (71.8%) was noted in GE than in GC (43.9%). Febrile neutropenia was also more common in GE (4 patients) than in GC (1 patient). However, delay of protocol treatment due to leukopenia was similar between the 2 arms. Data on the expresssion of the excission repair cross-complimentation 1 (ERCC1), evaluated by immunohistochemical study for patients with available tumor tissue, will be presented. Conclusions: Gemcitabine plus conventional-dose epirubicin is an effective and well-tolerated regimen for patients with stage IIIB/IV NSCLC. No significant financial relationships to disclose.

Abstract
1100 Background: The dose and schedule of paclitaxel have been evolving in the past 15 years. However, the lowest effective dose of weekly paclitaxel remains unclear. In this study, we examined if a very low dose of paclitaxel can be effective in MBC. Except for the dose of paclitaxel, the chemotherapy regimen and the patient population of this study were very similar to one of our previous report (Cancer 2002; 95:2044–50). Methods: Women with chemotherapy-naïve metastatic BC, adequate performance status and organ functions were eligible. All patients received paclitaxel, 50 mg/m2 iv 1 hr on D1, 8 and 15, and cisplatin, 40 mg/m2 iv 24 hrs on D1 and 8, every 4 weeks. Patients continued this low-dose regimen until progressive disease (PD) or prohibitive toxicities occurred. Patients who had PD or stable disease (SD) without clinical benefit were shifted to paclitaxel 80 mg/m2 iv 1 hr on D1, 8 and 15, and cisplatin, 40 mg/m2 iv 24 hrs on D1 and 8, every 4 weeks. The primary endpoint was overall response rate (ORR). Simon’s optimal two-stage design (P0, P1,a, and βare 20%, 40%, 0.05, and 0.2, respectively) was adopted. More than 4 objective responses were needed in the first 13 patients, and a total of 43 patients will be enrolled. Results: After a median follow-up duration of 16.5 months, 27 patients were evaluable for response and toxicity. Their median age was 52.7 years (range: 30.1∼69.4). Twenty patients were hormone receptor (+), while 6 patients were Her-2/neu (+). A total of 121 cycles of protocol treatment were administered as of Dec. 2006. There were 0 complete response and 14 partial responses, for an ORR of 51.9%. Nine of 14 responders remain progression-free. The PFS was 9.6 months (95% of CI: 5.53∼13.67%) and the OS not reached. Grade 3–4 anemia, neutropenia, liver toxicity, thrombocytopenia, and skin toxicities were reported in 8, 6, 2, 1, and 1 patients, respectively. Neurotoxicity was common (22/27), but all were grade 1 or 2. Conclusions: The preliminary results of this study suggest that weekly low-dose paclitaxel is as effective as conventional-dose paclitaxel, and the treatment-related toxicities were more acceptable.
