Abstract
Background With the increasing number of small pulmonary nodules detected, effective localization of pulmonary nodules has become an issue. The goal of this study is to determine the safety and feasibility of a newly developed augmented reality navigation technology for intraoperative localization of small pulmonary nodules. Methods We conducted a prospective single-center feasibility study of a novel augmented reality navigation system and lung localization (LungBrella) marker on ten patients between July and October 2020. For augmented reality navigation-guided localization, a preoperative chest computed tomography scan was performed to generate 3-dimensional (3D) virtual images and individualized localization plan, which were uploaded into Hololens (a head-mounted augmented reality device). Under the guidance of established procedure plan displayed by HoloLens, localization marker was placed in operating room. Segmentectomy or wedge resection was subsequently performed. The primary endpoint was the localization procedure success rate, and the secondary endpoints were localization time, operation time, and complications. Results Localization was successful in seven of the ten procedures. Due to different reasons, failures were noted in three cases, after which immediate adjustments were made. In the successful cases, the LungBrella marker was positioned at a median of 5.8 mm (range, 0-10 mm) from the edge of the nodule. Median localization time was 9.4 min (range, 5-19 min), and median operation time was 172.9 min (range, 105-200 min). There were no complications during the entire process. Conclusions This exploratory study suggests that augmented reality navigation-guided pulmonary nodule localization is a safe and feasible technique (ClinicalTrials.gov identifier, NCT04211051).

Morphological Analysis of Fractures of the Proximal Humerus by the Fracture Mapping Technique. Orthop Surg 2023; 15:2042-2051. [PMID: 36628500 PMCID: PMC10432501 DOI: 10.1111/os.13645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 12/05/2022] [Accepted: 12/08/2022] [Indexed: 01/12/2023] Open
Abstract
OBJECTIVE Fractures of different parts of the proximal humerus may lead to different postoperative functional deficits, but there are few studies on the morphology and related functions of the proximal humerus. The purpose of this study was to analyze the fracture pattern of the proximal humerus by the three-dimensional (3-D) fracture mapping technique and to further evaluate its clinical utility. METHODS Patients with proximal humeral fractures admitted to Pudong Hospital, Fudan University, from January 2018 to December 2020, were analyzed. Three surgeons divided the fractures into groups according to the 3-D CT imaging technique and mapped the fractures on a 3-D template according to the fracture line of each fracture. Finally, the humeral head inversion angle and the functional score were recorded in different fracture types. RESULTS A total of 312 cases of humeral fractures were included. Among them, there were 90 patients (28.8%) in the simple greater tuberosity + lesser tuberosity + medial cortex group, with typical fracture features of surgical neck fractures of the humerus + greater tuberosity fractures. Eighty-seven patients (27.9%) in the greater tuberosity + isolated fragment lesser tuberosity + medial cortex group had typical "four-part fractures." There were 45 patients (14.4%) in the greater tuberosity + lesser tuberosity + medial isolated fragment group. Moreover, more patients in this group had medial comminution due to varus displacement of the femoral head. There were 66 patients (21.1%) in the isolated greater tuberosity group, 21 patients (6.7%) in the greater tuberosity + lesser tuberosity group, and three patients (1.0%) in the greater tuberosity + medial cortex group. In addition, the humeral head inversion angle and other statistical differences were observed in the greater tuberosity + lesser tuberosity + medial isolated fragment group. CONCLUSIONS This morphological study helps to further identify the characteristics of proximal humerus fracture patterns, which may be closely related to different clinical outcomes. Further relevant studies are needed to verify the reliability of their clinical application and the potential value in surgical planning and postoperative functional rehabilitation.

A Canine Surgical Model of Stroke by Minimally Invasive Occlusion of the Proximal Middle Cerebral Artery. Bull Exp Biol Med 2023; 174:370-375. [PMID: 36735113 DOI: 10.1007/s10517-023-05710-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Indexed: 02/04/2023]
Abstract
In this study, a model of ischemic stroke by surgical proximal middle cerebral artery (MCA) occlusion was developed on 10 beagle dogs. The advantages of this model are the transtemporal approach and a minimally invasive surgical procedure. Dogs were randomly assigned to two groups: sham-operated (proximal MCA exposure without occlusion) and experimental (permanent proximal MCA occlusion) groups. Different evaluation methods were used to assess the consequences of MCA occlusion in dogs, including neurobehavioral tests, MRI, and immunohistochemical staining. Clear signs of cerebral infarction associated with the region supplied by MCA were confirmed and the model showed good repeatability and consistency. The model can serve as an appropriate large animal model to improve the translation of stroke therapeutics research from the laboratory to the clinical practice.

Chronotype and insomnia may affect the testosterone levels with a sexual difference: a Mendelian randomization. J Endocrinol Invest 2023; 46:123-132. [PMID: 35997959 DOI: 10.1007/s40618-022-01890-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Accepted: 07/29/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVE To evaluate the causal effects of sleep traits (i.e., chronotype, insomnia, and sleep duration) on bioavailable testosterone (BT), sex hormone-binding globulin (SHBG), and total testosterone (TT) levels in women and men. METHODS We performed Mendelian randomization (MR) using random-effect inverse-variance weighted (IVW) and 7 other MR analyses. Exposure data for sleep traits were obtained from the largest-to-date genome-wide association study (GWAS) from 339,926 to 1,331,010 individuals. Summary data for testosterone levels were obtained from GWAS based on the UK Biobank. RESULTS For women, our study supported that chronotype was associated with decreased BT (IVW: β = - 0.042, 95% CI - 0.060, - 0.023, p = 1.17E-05) and TT (IVW: - 0.053, 95% CI - 0.075, - 0.031, p = 2.30E-06). Besides, insomnia can significantly increase BT (IVW: β = 0.025, 95% CI 0.009, 0.041, p = 0.002). These findings were significant in most sensitivity analyses. For men, statistical significance was found between chronotype and BT (β = - 0.027, 95% CI - 0.048, - 0.005, p = 0.016), and insomnia and TT (β = - 0.028, 95% CI - 0.049, 0.007, p = 0.009) in IVW. However, the effect estimates were not broadly consistent with other sensitivity analyses. Our study did not find support for causal effects of sleep duration on testosterone levels in both women and men. CONCLUSION Our study reveals the sex differences in the effects of sleep traits on testosterone levels. A healthy sleep habit is vital for the maintenance of testosterone homeostasis in women. Further studies are warranted to investigate the associations between sleep traits and testosterone levels in men.

Abstract
Lung cancer is a malignant tumor with high morbidity and mortality in the world today. Emerging evidence suggests that PIWI-interacting RNAs (piRNAs) are aberrantly expressed in various human cancers, including lung cancer. Despite of the poorly understood mechanism, piRNAs may work as carcinogenic roles or tumor suppressors by engaging in a variety of cancer-associated signaling pathways. Therefore, they might serve as potential therapeutic targets, diagnostic indicators, or prognostic indicators in lung cancer. This review will discuss the new findings of piRNAs, including their biosynthetic processes, mechanisms of gene suppression, and the significance of these piRNAs tested in lung cancer samples to determine their involvement in cancer progression.

Anti-tumor effects of dual PI3K-HDAC inhibitor CUDC-907 on activation of ROS-IRE1α-JNK-mediated cytotoxic autophagy in esophageal cancer. Cell Biosci 2022; 12:135. [PMID: 35989326 PMCID: PMC9394063 DOI: 10.1186/s13578-022-00855-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 07/17/2022] [Indexed: 11/24/2022] Open
Abstract
Background PI3K-Akt pathway activation and the expression of histone deacetylases (HDACs) are highly increased in esophageal cancer, suggesting that inhibition of such targets may be a viable therapeutic strategy. Herein, we aimed to evaluate the anti-tumor effect of CUDC-907, a dual PI3K-HDAC inhibitor, in esophageal squamous cell carcinoma (ESCC). Methods The anti-tumor effects of CUDC-907 in ESCC were evaluated using cell counting kit-8, flow cytometry, and western blot. mRNA-sequencing was used to explore the mechanism underlying CUDC-907 anti-tumor effects. The relations of reactive oxygen species (ROS), lipocalin 2 (LCN2), and CUDC-907 were determined by flow cytometry, rescue experiments, and western blot. The activation of the IRE1α-JNK-CHOP signal cascade was confirmed by western blot. The in vivo inhibitory effects of CUDC-907 were examined by a subcutaneous xenograft model in nude mice. Results CUDC-907 displayed effective inhibition in the proliferation, migration, and invasion of ESCC cells. Through an mRNA-sequencing and functional enrichment analysis, autophagy was found to be associated with cancer cells death. CUDC-907 not only inhibited the PI3K-Akt-mTOR pathways to result in autophagy, but also induced ROS accumulation to activate IRE1α-JNK-CHOP-mediated cytotoxic autophagy by downregulating LCN2 expression. Consistently, the in vivo anti-tumor effects of CUDC-907 accompanied by the downregulated expression of p-mTOR and LCN2 and upregulated expression of p-IRE1α and LC3B-II were evaluated in a xenograft mouse model. Conclusion Our findings suggested the clinical development and administration of CUDC-907 might act as a novel treatment strategy for ESCC. A more in-depth understanding of the anti-tumor effect of CUDC-907 in ESCC will benefit the clinically targeted treatment of ESCC.

Abstract
Background Combined anatomic subsegmentectomy performed by video-assisted thoracic surgery or robot-assisted thoracic surgery is an emerging minimally invasive surgical technique for patients with early-stage non-small cell lung cancer (NSCLC). However, the early results of these two methods have barely been studied. Methods A retrospective analysis of medical records from Shanghai Ruijin Hospital between July 2017 and August 2021 included 62 patients, 32 of whom underwent video-assisted combined anatomic pulmonary subsegmentectomy and 30 underwent robot-assisted combined anatomic pulmonary subsegmentectomy. Perioperative outcomes were compared. Results Sixty-two patients with comparable baseline characteristics were included in this study. No significant difference was found in the length of postoperative hospital stay, operation duration, intraoperative blood loss and the rate of overall complications between the robot-assisted and video-assisted groups. A higher cost was observed in the robot-assisted group compared to the video-assisted group. There were more N1 lymph nodes and N1 stations dissected in the robot-assisted group compared with the video-assisted group; the same results were observed with regard to the number of N2 lymph nodes and N2 stations dissected. Conclusions It is safe and feasible for the patients with early-stage NSCLC to be treated with combined anatomic subsegmentectomy performed via robot-assisted or video-assisted thoracic surgery. The robotic approach may contribute to the potential improvements in N1 and N2 lymph node retrieval.

Abstract
In recent years, there have been several outbreaks of infectious diseases around the world, including severe acute respiratory syndrome, Ebola virus disease, Middle East respiratory syndrome, and corona virus disease 2019. Experience suggests that the detection and research of emergent infectious diseases play a crucial role in the process of responding to the epidemic, which also brings great challenges to biosafety laboratories. In the face of unknown biological risk factors, the non-standard biosafety protection measures have a serious impact on the life safety of laboratory staff and the research of infectious diseases, which stresses the necessity of safety protection in biosafety laboratories. This article will briefly review the current status and future prospect of management of biosafety laboratories both in China and other countries in terms of safety protection measures during new sudden infectious disease incidents.

Abstract
BACKGROUND This study investigated the effects of posteromedial fracture fragments on the postoperative stability of intertrochanteric fractures of the femur by analyzing the quantity and range of fragments in CT 3D reconstruction. MATERIALS AND METHODS Patients diagnosed with femoral lesser trochanter fractures were collected from September 2015 to February 2018. CT 3D reconstruction was applied to evaluate the quantity and extension of posteromedial fragments and the presence of isolated medial fragments. The stability of postoperative fracture was evaluated by comparing the changes of "neck-shaft angle" and "telescoping" from 1 week to 1 year after operation. RESULTS A total of 143 patients were finally confirmed, in which 63 patients contained isolated fragments on the medial side, and the average number of fragments in the posteromedial side was 1.93 ± 0.34, which accounted for an average of about 86.11% ± 8.20% in the whole posteromedial wall. When the number of posteromedial fragments was > 2 and the range of posteromedial fragments was > 75%, then the changes in the neck-shaft angle and "telescoping" showed statistical significance (12.27 ± 4.18 mm and 10.13 ± 6.17°, respectively), and when there were isolated medial isolated fragments, then the change in the neck-shaft angle was 10.66 ± 4.27°, showing statistical significance. CONCLUSIONS These findings revealed a certain correlation between the quantity and the range of posteromedial fragments and the postoperative "shortening" and "collapse" of femoral intertrochanteric fractures.

Abstract
A nidovirus was isolated from crucian carp (Carassius auratus). The complete genome of the crucian carp nidovirus (CCNV) is 25,971 nt long and has five open reading frames, encoding the polyprotein 1ab (pp1ab), spike glycoprotein (S), membrane protein (M), and nucleocapsid protein (N). CCNV has the highest similarity to Chinook salmon nidovirus (CSNV). However, the CCNV HB93 pp1ab protein sequence has three long fragment deletions compared with the CSNV. Phylogenetic analysis based on the complete genome sequence showed that CCNV HB93 clusters with CSNV, indicating that CCNV represents a second species in the new genus Oncotshavirus within the new family Tobaniviridae in the order Nidovirales.

Abstract
Betalains have high nutritional value and bioactivities. Red pulp pitaya (Hylocereus polyrhizus) is the only fruit containing abundant betalains for consumer. However, no information is available about genes involved in betalain biosynthesis in H. polyrhizus. Herein, two cDNA libraries of pitaya pulps with two different coloration stages (white and red pulp stages) of Guanhuahong (H. polyrhizus) were constructed. A total of about 12 Gb raw RNA-Seq data was generated and was de novo assembled into 122,677 transcripts with an average length of 1183 bp and an N50 value of 2008. Approximately 99.99% of all transcripts were annotated based on seven public databases. A total of 8871 transcripts were significantly regulated. Thirty-three candidate transcripts related to betalain biosynthesis were obtained from the transcriptome data. Transcripts encoding enzymes involved in betalain biosynthesis were analyzed using RT-qPCR at the whole pulp coloration stages of H. polyrhizus (7-1) and H. undatus (132-4). Nine key transcripts of betalain biosynthesis were identified. They were assigned to four kinds of genes in betalain biosynthetic pathway, including tyrosinase, 4, 5-DOPA dioxygenase extradiol, cytochrome P450 and glucosyltransferase. Ultimately, a preliminary betalain biosynthetic pathway for pitaya was proposed based on betalain analyses, gene expression profiles and published documents.

Abstract
BACKGROUND Vitiligo is an autoimmune chronic depigmentation disorder caused by melanocyte loss. Previous studies found that CD4(+)CD25(+) regulatory T-cell (Treg) dysfunction was involved in the pathogenesis of vitiligo and that gene polymorphisms in forkhead box P3 (FOXP3) - a master regulator of Treg development and function - were associated with susceptibility to some autoimmune disorders. Therefore, we hypothesized that functional polymorphisms of the FOXP3 gene might be associated with vitiligo via dysregulation of Treg cells. OBJECTIVES To evaluate whether FOXP3 polymorphisms are associated with vitiligo risk. MATERIAL AND METHODS In this hospital-based case-control study of 682 patients with vitiligo and 682 vitiligo-free age- and sex-matched controls, we genotyped three single nucleotide polymorphisms (SNPs) of the FOXP3 gene - rs2232365, rs3761548 and rs5902434 - by performing polymerase chain reaction with sequence-specific primers (PCR-SSP). RESULTS Significantly increased vitiligo risk was associated with the rs2232365 GG [odds ratio (OR) 1·68, 95% confidence interval (CI) 1·17-2·39, P = 0·004] and rs3761548 AA (OR 1·82, 95% CI 1·10-3·01, P = 0·033) genotypes compared with the rs2232365 AA and rs3761548 CC genotypes. On combined analysis of these three variant alleles, we found that individuals carrying 2-6 variant alleles had significantly increased vitiligo risk (OR 1·34, 95% CI 1·08-1·66). This risk was more pronounced in the following subgroups: age > 20 years, male sex, active vitiligo, nonsegmental vitiligo and other accompanying autoimmune diseases. CONCLUSIONS FOXP3 gene polymorphisms contributed to vitiligo risk in a Han Chinese population.

Abstract
AIM This study aims to investigate and evaluate the efficacy and safety of early enteral nutrition (EN) in maintaining and improving the postoperative nutritional status in patients undergoing esophagectomy. METHODS A randomized, controlled clinical trial was conducted in 120 adult patients with esophageal cancer and undergoing esophagectomy. Patients were randomly divided into two groups receiving either EN (N.=64) or parenteral nutrition (PN) (N.=56) postoperatively. The nutritional intake was isonitrogenic and isocalorie for both groups. Nutritional status was evaluated preoperatively as well as on postoperative day I and day 8. Daily nitrogen balance was measured and 7-day cumulative nitrogen balance was calculated. The levels of serum markers including d-lactate, diamine oxidase (DAO), and endotoxin were determined on 1st, 4th and 8th postoperative day for analyzing intestinal barrier function. Postoperative infection rate and the incidence of nutrition support-related complications were examined. RESULTS The concentrations of serum albumin and prealbumin in patients of EN group were significantly higher than those in PN group and the concentrations of blood glucose, γ-GT, AKP, TB, and DB were significantly lower compared to those in the PN group (P<0.05). Both daily nitrogen balance and cumulative nitrogen balance of EN group were better than those of PN group since postoperative day III. The serum levels of d-lactate, DAO, and endotoxin of EN group were significantly lower than those of PN group on postoperative day VIII (P<0.01). The incidence of postoperative infections in blood, lung, and intestinal tract in EN group was lower compared to PN group (P<0.05). No severe complications associated with nutritional support occurred in EN group. The time to flatus passage in EN group was significantly shorter, and the cost of nutritional support was significantly less compared to PN group (P<0.05). CONCLUSION Postoperative early enteral nutrition was safe and feasible for patients undergoing esophagectomy. Compared to PN, EN more efficiently ameliorated postoperational nutritional status of the patients undergoing esophagectomy, played an important role in restoring intestinal barrier function postoperatively, reduced the incidence of postoperative infection, and decreased the cost of hospital stay.

Abstract
AIM Aim of the present study was to compare the effectiveness of plaque excision in management of lower limb ischemia of atherosclerosis and in-stent restenosis with the SilverHawk atherectomy catheter. METHODS From November 2010, to August 2011, 43 patients were involved and completed follow-up. They were divided into two groups: group A is the atherosclerotic plaque group (16 cases, 37.2%) and group B is the in-stent restenosis/occlusion lesion group (27 cases, 62.8%). The average age of group A was 68.3 years and group B was 72 years, the mean duration was 27.4 months and 26 months, respectively. Intermittent claudication was 8 cases and 16 cases respectively, and rest pain both was 4 cases, foot ulcer was 1 case and 4 cases, toe gangrene both was 3 cases. Ankle Brachial Index (ABI)≤0.4 was 2 in group A and 8 in group B, ABI>0.4 was 12 and 16, ABI=0 was 2 and 3, respectively. Excision with protective devices in 6 cases. Nine cases and 17 cases received treatment for proximal and distal lesions over the same period, respectively, included the proximal iliac artery stenting 1 case in group A and 5 cases in group B, distal calf arteries stenting 6 cases in group A and 11 cases in group B, balloon angioplasty 2 in group A and 1 in group B. Endpoints included postoperative mortality or amputation of target limb. RESULTS Forty-one operations were successful, the technical success rate was 95.3%, one case in group B suffered above-knee amputation. The target vessels of 41 patients maintain patency after discharge. Postoperative claudication distance increased to 500 meters except for one case in each group, all 4 rest pain patients got alleviated, reduced toe ulcer area happened in 1 and 2 cases respectively, all 3 cases of gangrene dried up/infection controlled in each group. Postoperative ABI result 0.7-0.8: 4 in group A and 5 in group B; 0.81-0.9 was 5 and 8; >0.91 was 6 and 13, respectively. Symptom improvement result had no significant difference between the two groups (P>0.05). Follow-up covered 41 patients, average 17.5±3.3 months. Group A patients stayed in good condition, 7 claudication patients's walking distance above 500 meters remains; rest pain no recurrence, one ulcer healing, 2 of 3 toe gangrene self-shedding and stump healing, 1 toe gangrene removed by surgery and wound healing. Group B, 4 of 15 claudication cases recurrence, and received plaque excision again. Rest pain no recurrence. 3 of 4 ulcer healing, 1 ulcer area reduced significantly. One out of 3 gangrene received below knee amputation (toe osteomyelitis), wound healing. One recurrence, angiography showed in-stent severe restenosis, received plaque excision again. One toe gangrene removed by surgery and wound healing. CONCLUSION Plaque excision with "SilverHawk" treatment for lower limb ischemia of atherosclerosis or in-stent restenosis is safe and effective. No significant difference for these two lesions in efficacy. Long term follow-up and larger randomized study is needed for further information on treatment.

Abstract
BACKGROUND Vitiligo is an acquired depigmentation disorder resulting from selective destruction of melanocytes. The aryl hydrocarbon receptor (AHR) is vital to the regulation of melanogenesis and melanocyte proliferation and differentiation through modulating the expressions of melanogenesis-related genes. AHR mutations may negatively affect AHR proteins and its target genes. Therefore, we hypothesized that AHR polymorphisms might be involved in vitiligo by impacting the transcriptional activities of related genes as mentioned above. OBJECTIVES To evaluate the potential association between AHR polymorphisms and vitiligo susceptibility. METHODS We performed a hospital-based, case-control study of 1000 patients with vitiligo and 1000 vitiligo-free but age- and gender-matched controls. Two single nucleotide polymorphisms of the AHR gene (rs10249788 and rs2066853) were selected and genotyped using a polymerase chain reaction-restriction fragment length polymorphism method. RESULTS A statistically significantly decreased risk of vitiligo was found to be associated with the TT and CT genotypes of rs10249788 [odds ratio (OR) 0·59, 95% confidence interval (CI) 0·38-0·93; P = 0·028 and OR 0·82, 95% CI 0·68-0·98; P = 0·032, respectively] as well as among subgroups: male, active, nonsegmental vitiligo, and onset age ≤ 20 years. Moreover, subjects with the combined (CT + TT)/GG genotype or T/G haplotype (rs10249788/rs2066853) showed a decreased risk for vitiligo (OR 0·57, 95% CI 0·37-0·87, P = 0·009 and OR 0·78, 95% CI 0·64-0·96, P = 0·033, respectively). CONCLUSIONS These results suggest that the T allele of rs10249788 located in the promoter of the AHR gene is associated with a protective effect on vitiligo in Han Chinese populations.

Abstract
A 6-year-old Basset hound developed a progressive central nervous system disease culminating in epileptic seizures. Histologically, Lafora bodies were found in neurones of the middle and deeper cerebral cortex and midbrain, in Purkinje cells and their processes, and in glial cells of the molecular layer of the cerebellum. Many were also observed free in the neuropil. The ultrastructural and histochemical characteristics of the bodies were similar to those described in previous human and canine cases of Lafora's disease.

Abstract
160 Background: In Asia, where hepatitis B is very common, patients often present with locally advanced or metastatic hepatocellular carcinoma (HCC), and their prognosis is poor. The EACH study was designed to evaluate the efficacy and safety of FOLFOX4 vs. doxorubicin as palliative systemic chemotherapy in advanced HCC. Methods: The open-label, randomized, multicenter phase III study was conducted in 371 patients in China, Taiwan, Korea and Thailand, who had locally advanced or metastatic HCC and were ineligible for resection. Patients were randomized 1:1 to receive either FOLFOX4 (oxaliplatin 85 mg/m2 i.v. d1; LV 200 mg/m2 i.v. h0–h2 d1 and d2; 5FU 400 mg/m2 i.v. bolus h2, then 600 mg/m2 over 22 hours d1 and d2 q2w) or doxorubicin (50 mg/m2 i.v. q3w). The primary endpoint was overall survival (OS); secondary endpoints included progression-free survival (PFS), response rate (RR) by RECIST and safety. Data from final and follow-up analyses of the intent-to-treat (ITT) population and selected subgroup analyses are presented. Results: At the final analysis, median OS with FOLFOX4 (N = 184) was 6.40 months (95% CI: 5.30, 7.03) vs. 4.97 months (95% CI: 4.23, 6.03) with doxorubicin [N = 187; p = 0.0695 using a stratified log-rank test; statistical significance (p = 0.0425) was achieved at the post hoc follow-up analysis conducted 7 months later]. Median PFS with FOLFOX4 was 2.93 months (95% CI: 2.43, 3.53) vs. 1.77 months with doxorubicin (95% CI: 1.63, 2.30; p = 0.0002). The RR was 8.2% vs. 2.7% of patients with FOLFOX4 and doxorubicin, respectively (p = 0.0233), and the disease control rate (DCR) was 52.2% vs. 31.6% (p < 0.0001). In the Chinese sub-population, OS, PFS, RR and DCR were significantly improved with FOLFOX4 vs. doxorubicin at both the final and follow-up analyses. In the other subgroups analyzed, the OS and PFS benefits of FOLFOX4 vs. doxorubicin were generally consistent. Conclusions: In the ITT population, median OS was greater with FOLFOX4 than doxorubicin throughout the study and statistical significance was achieved after continued follow-up. FOLFOX4 can benefit patients with advanced HCC, as it significantly increases median OS, PFS, RR and DCR compared with doxorubicin. [Table: see text]
