[PMID: 36307666 DOI: 10.1245/s10434-022-12694-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Accepted: 10/04/2022] [Indexed: 01/10/2023]
Abstract
BACKGROUND The standard treatment for locoregionally advanced unresectable esophageal squamous cell carcinoma was radical chemoradiotherapy. However, the prognosis was modest. Emerging evidence showed the concept of induction chemotherapy with a goal of conversion surgery. METHODS We reviewed the long-term, clinical outcomes and safety data of induction chemotherapy using docetaxel-cisplatin-5FU (DCF) and subsequent definitive treatment, either surgery or radical chemoradiotherapy (CRT), in locally advanced unresectable esophageal cancer in Queen Mary Hospital, Hong Kong. A total of 47 patients (median age 62 years, male: 41 (87.2%)) with locoregionally advanced unresectable esophageal cancer received induction DCF. The response rate was 65.9% (complete/partial response: n = 31). After induction DCF, 24 patients (41.4%) had radical surgery and 7 (14.9%) had definitive CRT. RESULTS The median overall survival (mOS) was significantly longer in patients received subsequent surgery compared with those with definitive CRT (mOS: 40.2 vs. 9.1 months, hazard ratio 3.33, 95% confidence interval 1.22-9.07, p = 0.02) and no definitive treatment (mOS: 40.2 vs. 6.3 months, hazard ratio 8.51, 95% confidence interval 3.7-19.73, p < 0.001). Patients who received surgery, female, and those with supraclavicular lymph node involvement had a better OS. Twenty-one patients (44.7%) developed grade 3/4 adverse events during induction DCF, and two died after chemotherapy because of trachea-esophageal fistula complicated with sepsis. Eleven patients who had surgery had postoperative complications and none had postoperative mortality. CONCLUSIONS Induction DCF and subsequent conversion surgery offered a chance of cure with long-term survival benefit and manageable toxicities in patients with locoregionally advanced unresectable esophageal cancer.

Multicentre Comparison of the Toxicity and Effectiveness of Lobaplatin-Based Versus Cisplatin-Based Adjuvant Chemotherapy in Oesophageal Carcinoma. Front Oncol 2021; 11:668140. [PMID: 34589419 PMCID: PMC8474464 DOI: 10.3389/fonc.2021.668140] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Accepted: 08/30/2021] [Indexed: 11/30/2022] Open
Abstract
Objectives Lobaplatin (LBP), a third-generation cisplatin derivative has shown promising activity and few side effects in oesophageal squamous cell carcinoma (ESCC) in previous reports. We compared LBP plus docetaxel with cisplatin plus docetaxel as adjuvant chemotherapy in ESCC patients to determine the effects on overall survival (OS) and toxicity. Methods A multicentre retrospective study was performed using propensity score matching (PSM) with the Medicine-LinkDoc database. Patients diagnosed with stage II-III ESCC treated with adjuvant chemotherapy (cisplatin plus docetaxel or LBP plus docetaxel) between January 2013 and December 2016 were selected from 6 centres in China. Results There were 733 eligible ESCC patients. After PSM (1:1 ratio), 458 patients remained. The 5-year OS rates of the cisplatin and LBP groups were 25.9% and 23.6%, respectively (P=0.457). Leukopenia (grade III-IV/I-II/0: 2.62%/34.5%/59.39% versus 5.24%/43.23%/45.85%; P=0.0176), neutropenia (grade III-IV/I-II/0: 6.55%/37.56%/51.09% versus 4.37%/53.28%/36.34%; P=0.0015), nephrotoxicity (grade I-II/0: 13.97%/76.86% versus 26.64%/65.94%; P<0.001) and gastrointestinal symptoms (grade III-IV/I-II/0: 2.18%/54.59%/32.31% versus 6.55%/65.07%/20.88%; P=0.0011) were more frequent in the cisplatin group. Conclusions Compared with cisplatin plus docetaxel, LBP plus docetaxel provided the same survival benefits but lower side effects of myelosuppression and gastrointestinal symptoms. LBP plus docetaxel might be a choice for adjuvant chemotherapy in ESCC. Clinical Trial Registration Lobaplatin or Cisplatin in Adjuvant Chemotherapy for Oesophageal Carcinoma, identifier NCT03413436.

Abstract
Objective: Perioperative chemotherapy can potentially downstage esophageal cancer, reducing the risk of early systemic dissemination. One recommended neoadjuvant regimen for managing gastroesophageal junction and esophageal cancer is docetaxel, cisplatin, and 5-fluorouracil (DCF). To address the high toxicity profile of DCF, modifications in dosages and treatment intervals have been studied. We integrated a modified DCF regimen (mDCF) into a multimodal treatment approach for non-metastatic esophageal cancer (nMEC). Retrospectively, we sought to describe our community experience of administrating neoadjuvant mDCF to patients with nMEC.Design: Patients diagnosed with nMEC between August 2008 and November 2017 and prescribed mDCF were identified for retrospective review. Outcomes of interest included disease-free survival (DFS), overall survival (OS), and hematologic toxicities. Analyses were performed using SAS 9.4.Results: Thirty patients met inclusion criteria with a median age of 64.9 years; 90% were male. The 2-year and 5-year DFS was 60.8% and 41.7%, respectively, for adenocarcinoma and 71.4% and 71.4% for squamous cell carcinoma (SCC). The 2-year and 5-year OS was 64.9% and 44.5%, respectively, for adenocarcinoma and 71.4% and 71.4% for SCC. Both DFS and OS decreased with increasing disease stage, histology (adenocarcinoma versus squamous), esophageal compared to esophagogastric-junction involvement, and without surgical intervention. Frequent toxicity grades for leukopenia and thrombocytopenia were Grades I and II.Conclusion: Using an mDCF regimen in combination with chemoradiation +/- surgical resection in a community setting appears to have an acceptable toxicity profile as well as DFS and OS outcomes compared to chemotherapeutic regimens reported in other similar studies.

Abstract
Background Chemoresistance is one of the major obstacles for cancer therapy in the clinic. Circular RNAs (circRNAs) are involved in the pathogenesis of esophageal squamous cell carcinoma (ESCC) and chemoresistance. This study aimed to explore the role and molecular mechanism of circ_0006168 in Taxol resistance of ESCC. Methods The expression levels of circ_0006168, microRNA-194-5p (miR-194-5p) and jumonji domain containing 1C (JMJD1C) were measured by quantitative real-time polymerase chain reaction (qRT-PCR) or western blot. The half-inhibition concentration (IC50) value of Taxol was evaluated by Cell Counting Kit-8 (CCK-8) assay. Cell proliferation was evaluated by CCK-8 and colony formation assays. Cell migration and invasion were detected by transwell assay. Cell apoptosis was determined by flow cytometry. The interaction between miR-194-5p and circ_0006168 or JMJD1C was predicted by bioinformatics analysis (Circinteractome and TargetScan) and verified by dual-luciferase reporter and RNA Immunoprecipitation (RIP) and RNA pull-down assays. The mice xenograft model was established to investigate the roles of circ_0006168 in vivo. Results Circ_0006168 and JMJD1C were upregulated and miR-194-5p was downregulated in ESCC tissues, ESCC cells, and Taxol-resistant cells. Functionally, knockdown of circ_0006168 or JMJD1C increased Taxol sensitivity of ESCC in vitro via inhibiting cell proliferation, migration and invasion, and promoting apoptosis. Moreover, circ_0006168 could directly bind to miR-194-5p and JMJD1C was verified as a direct target of miR-194-5p. Mechanically, circ_0006168 was a sponge of miR-194-5p to regulate JMJD1C expression in ESCC cells. Furthermore, JMJD1C overexpression reversed the promotive effect of circ_0006168 knockdown on Taxol sensitivity. Besides, circ_0006168 silence suppressed tumor growth in vivo. Conclusion Circ_0006168 facilitated Taxol resistance in ESCC by regulating miR-194-5p/JMJD1C axis, providing a promising therapeutic target for ESCC chemotherapy.

HERES, a lncRNA that regulates canonical and noncanonical Wnt signaling pathways via interaction with EZH2. Proc Natl Acad Sci U S A 2019; 116:24620-24629.

Abstract
Aberrant lncRNA expression is responsible for cancer progression and metastasis, positioning lncRNAs not only as biomarkers but also as promising therapeutic targets for curing cancer. A number of lncRNAs have been reported in ESCC but their mechanistic roles largely remain unknown. Wnt signaling pathways are often dysregulated in ESCC; however, the role of lncRNAs in such dysregulation was also undetermined. We found 6 lncRNAs that are significantly dysregulated and correlated with outcomes in ESCC patients. The most upregulated lncRNA, HERES, promotes cancer progression and epigenetically regulates canonical and noncanonical Wnt signaling pathways simultaneously through interaction with EZH2. These results show that HERES represents an early diagnostic and therapeutic target for squamous-cell-type cancers caused by defects in Wnt signaling pathways. Wnt signaling through both canonical and noncanonical pathways plays a core role in development. Dysregulation of these pathways often causes cancer development and progression. Although the pathways independently contribute to the core processes, a regulatory molecule that commonly activates both of them has not yet been reported. Here, we describe a long noncoding RNA (lncRNA), HERES, that epigenetically regulates both canonical and noncanonical Wnt signaling pathways in esophageal squamous cell carcinoma (ESCC). For this study, we performed RNA-seq analysis on Korean ESCC patients and validated these results on a larger ESCC cohort to identify lncRNAs commonly dysregulated in ESCCs. Six of the dysregulated lncRNAs were significantly associated with the clinical outcomes of ESCC patients and defined 4 ESCC subclasses with different prognoses. HERES reduction repressed cell proliferation, migration, invasion, and colony formation in ESCC cell lines and tumor growth in xenograft models. HERES appears to be a transacting factor that regulates CACNA2D3, SFRP2, and CXXC4 simultaneously to activate Wnt signaling pathways through an interaction with EZH2 via its G-quadruple structure-like motif. Our results suggest that HERES holds substantial potential as a therapeutic target for ESCC and probably other cancers caused by defects in Wnt signaling pathways.

Histological changes of superficial esophageal squamous cell carcinoma after preoperative chemotherapy. Esophagus 2018; 15:10.1007/s10388-018-0626-8. [PMID: 29909488 DOI: 10.1007/s10388-018-0626-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2017] [Accepted: 06/07/2018] [Indexed: 02/03/2023]
Abstract
INTRODUCTION We aimed to analyze the clinical and histological effects of chemotherapy in superficial esophageal squamous cell carcinoma (SESCC). METHODS We analyzed tumor samples from five patients with cT1bN1M0 who underwent subtotal esophagectomy following two courses of a new triplet chemotherapy regimen including docetaxel, cisplatin, and 5-fluorouracil (DCF). To assess the histological effects of chemotherapy, resected specimens were analyzed by macroscopic examination, hematoxylin & eosin (HE) staining, immunohistochemical (IHC) staining (p53, Ki-67 and cytokeratin) and periodic acid-Schiff (PAS) staining. RESULTS All five patients had a pathological T stage of T0/1a-LPM/1a-MM/1b (1/2/1/1) and histological grade of grade1a/1b/2/3 (1/1/2/1). Endoscopic examination revealed substantial shrinkage of lugol-voiding lesions (LVLs) in all cases. One case showed complete LVL disappearance, and resected specimen examination confirmed pathological complete response (pCR). IHC and PAS staining revealed that most initial LVLs were PAS-negative. Obvious viable cells were confirmed in two cases. The other three cases exhibited nuclear atypia and strong expression of p53 and Ki-67 in the basal layer of mucosa or lamina propria mucosae, even though the superficial layer of mucosa showed no obvious LVLs with PAS-positive. p53-positive lesions were also observed in Ki-67-positive. This indicated discordance between the endoscopic findings and histopathological evaluation. CONCLUSION DCF chemotherapy alone had a substantial therapeutic effect on SESCC in all cases. However, despite the normal appearance of the mucosal surface, viable cancer cells remained below the basal layer of mucosa. Careful attention should be paid when diagnosing clinical CR, or securing a resection margin of SESCC after DCF chemotherapy.

Abstract
Taxanes are chemotherapeutic agents commonly used to treat several cancers. However, the effects of taxanes on advanced gastric cancer (AGC) are still not clear, especially when used as a first-line treatment. This systematic review and meta-analysis aims to investigate the efficacy and safety of taxanes as a first-line treatment of AGC. The quality of our included studies was assessed using the Cochrane risk of bias tool for RCTs and NOS scale for nRCTs, and the data of the included studies was of satisfactory quality to analyze. The outcomes included overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and toxicity. Taxanes significantly improved OS (HR = 0.84, 95% CI 0.76-0.92, P = 0.0004) and had a slight effect on ORR (RR = 1.23, 95% CI 1.00-1.51, P = 0.05). However, taxanes may also increase the risks of neutropenia and leucopenia, similar to effects observed in other conventional chemotherapeutic treatments such as oxaliplatin and epirubicin. Therefore, patient characteristics including concomitant diseases, physical condition, and prior therapies should be considered before selecting taxane-based treatments for AGC.

Abstract
Multidrug resistance (MDR) is the major underlying cause of the low 5-year survival rate of esophageal carcinoma. In this study, we developed a novel microemulsion system (SD-ME) co-loaded with docetaxel (DTX) and Schizandrin A, a potent chemotherapeutic agent and a potential drug resistance modulator, respectively. In the physicochemical characterization studies, SD-ME displayed a well-defined spherical shape and size (56.62 ± 4.16 nm), a narrow polydispersity index (PDI, 0.132 ± 0.002), and a negative surface charge (−19.81 ± 3.11 mv). In the cellular uptake studies, SD-ME with a DTX concentration of 30 μg/mL exhibited a 3.9-fold enhancement of DTX internalization in DTX-resistant EC109 (EC109/DDR) cells in comparison to that observed for EC109 cells, and the mechanisms were associated with reducing P-gp expression and inhibiting P-gp ATPease. The half-maximal inhibitory concentrations (IC50) of DTX and SD-ME against EC109/DDR cells were 40.57 ± 0.39 and 3.59 ± 0.06 μg/mL, respectively. Likewise, the apoptotic rate of EC109/DDR treated with SD-ME increased up to 20-fold compared to that observed with free DTX. In anticancer efficacy studies in vivo, SD-ME markedly retarded the tumor growth of nude mice bearing EC109/DDR tumor xenografts compared with D-ME and free DTX throughout the duration of study. Consequently, mice treated with SD-ME had the highest survival rate (37.5%) during the observation period (70 days). In addition, there were no apparent side effects after the administration of SD-ME. Overall, our study provides evidence for SD-ME as an effective drug delivery system for enhanced MDR tumor treatment.
