Improper lung volume-dose parameters are risk factors for acute fatal radiation pneumonitis among esophageal cancer patients receiving chemoradiotherapy: a case-control study.

Background: Definitive concurrent chemoradiotherapy (DCRT) is the standard treatment for locally advanced unresectable esophageal cancer (EC). However, acute fatal radiation pneumonitis (AFRP) is one of the most harmful complications and it is still controversial which factors pose a greater risk.

Aim: This case-control study aims to investigate the relationship between AFRP and lung volume-dose parameters in patients with esophageal cancer undergoing DCRT.

Capecitabine or Capecitabine Plus Oxaliplatin Versus Fluorouracil Plus Cisplatin in Definitive Concurrent Chemoradiotherapy for Locally Advanced Esophageal Squamous Cell Carcinoma (CRTCOESC): A Multicenter, Randomized, Open-Label, Phase 3 Trial.

Purpose: This phase 3 trial aimed to compare the efficacy and safety of capecitabine or capecitabine plus oxaliplatin (XELOX) with those of fluorouracil plus cisplatin (PF) in definitive concurrent chemoradiotherapy (DCRT) for inoperable locally advanced esophageal squamous cell carcinoma (ESCC).

Methods: Patients were randomly assigned to receive two cycles of capecitabine, XELOX, or PF along with concurrent intensity-modulated radiation therapy. Patients in each arm were again randomly assigned to receive two cycles of consolidation chemotherapy or not.

GASC1-Adapted Neoadjuvant Chemotherapy for Resectable Esophageal Squamous Cell Carcinoma: A Prospective Clinical Biomarker Trial.

Neoadjuvant chemotherapy (NCT) is a standard care for esophageal squamous cell carcinoma (ESCC), but the efficacy is unsatisfactory. Cancer stem cells (CSCs) play key roles in chemotherapy resistance. Gene amplified in squamous cell carcinoma 1 (GASC1) is a neoteric gene in stemness maintaining of ESCC.

GASC1 Promotes Stemness of Esophageal Squamous Cell Carcinoma via NOTCH1 Promoter Demethylation.

The highest incidence of esophageal squamous cell carcinoma (ESCC) occurs in China. Cancer stem cells play key roles for tumor progression. Gene amplified in squamous cell carcinoma 1 (GASC1) is essential to maintain self-renewal and differentiation potential of embryonic stem cells.

Chemoradiation versus oesophagectomy for locally advanced oesophageal cancer in Chinese patients: study protocol for a randomised controlled trial.

Background: Surgery is the gold standard treatment for local advanced disease, while definitive concurrent chemoradiotherapy (DCRT) is recommended for those who are medically unable to tolerate major surgery or medically fit patients who decline surgery. The primary aim of this trial is to compare the outcomes in Chinese patients with oesophageal squamous cell cancer with locally advanced resectable disease who have received either surgery or DCRT.

Methods/design: One hundred ninety-six patients with T1bN + M0 or T2-4aN0-2 M0 oesophageal squamous cell cancer will be randomised to the DCRT group or the surgery group.

Palliative Care in the Global Setting: ASCO Resource-Stratified Practice Guideline.

Purpose The purpose of this new resource-stratified guideline is to provide expert guidance to clinicians and policymakers on implementing palliative care of patients with cancer and their caregivers in resource-constrained settings and is intended to complement the Integration of Palliative Care Into Standard Oncology Care: American Society of Clinical Oncology Clinical Practice Guideline Update of 2016. Methods ASCO convened a multidisciplinary, multinational panel of experts in medical oncology, family medicine, radiation oncology, hematology/oncology, palliative and/or hospice care, pain and/or symptom management, patient advocacy, public health, and health economics. Guideline development involved a systematic literature review, a modified ADAPTE process, and a formal consensus-based process with the Expert Panel and additional experts (consensus ratings group).

KDM4C, a H3K9me3 Histone Demethylase, is Involved in the Maintenance of Human ESCC-Initiating Cells by Epigenetically Enhancing SOX2 Expression.

Our studies investigating the existence of tumor-initiating cell (TIC) populations in human esophageal squamous cell carcinoma (ESCC) had identified a subpopulation of cells isolated from ESCC patient-derived tumor specimens marked by an ALDH phenotype bear stem cell-like features. Importantly, KDM4C, a histone demethylase was enhanced in ALDH subpopulation, suggesting that strategies interfering with KDM4C may be able to target these putative TICs. In the present study, by genetic and chemical means, we demonstrated that, KDM4C blockade selectively decreased the ESCC ALDH TICs population in vitro and specifically targeted the TICs in ALDH-derived xenograft, retarding engraftment.

A case of gastric adenocarcinoma metastasis to the esophagus possibly caused by gastroscopy or gastric reflux.

Recurrence after curative resection for gastric cancer is high, the pattern of recurrence include haematogenous metastasis, peritoneal metastasis, lymph node metastasis, and local recurrence, respectively. Here we report a case with local recurrence at the beginning, and subsequent metastasis to the esophagus three month following gastroscopy. Biopsy of the nodule in the upper esophagus was taken, pathology showed the adenocarcinoma of gastric origin.

Presence of Porphyromonas gingivalis in esophagus and its association with the clinicopathological characteristics and survival in patients with esophageal cancer.

Background: Mounting evidence suggests a causal relationship between specific bacterial infections and the development of certain malignancies. However, the possible role of the keystone periodontal pathogen, Porphyromonas gingivalis, in esophageal squamous cell carcinoma (ESCC) remains unknown. Therefore, we examined the presence of P.

Gastric cardia adenocarcinoma microRNA profiling in Chinese patients.

Gastric cardia adenocarcinoma (GCA), which occurs at the gastroesophageal boundary, is one of the most malignant types of cancer. Over the past 30 years, the incidence of GCA has increased by approximately sevenfold, which has a more substantial increase than that of many other malignancies. However, as previous studies mainly focus on non-cardia gastric cancer, until now, the mechanisms behind GCA remain largely unknown.

Evaluation of combined argon plasma coagulation and Savary Bougienage for the relief of anastomotic-stenosis after esophageal squamous cancer surgery.

Background: Several endoscopic dilation techniques have been reported for treatment of anastomotic-stenosis of esophageal cancer, but the high incidence of dysphagia has remained unchanged. The aim of this study was to compare the effect of Argon Plasma Coagulation (APC) combined with Savary Bougienage (SB) compared to APC alone or SB alone for anastomotic-stenosis after radical operation for squamous cell carcinoma of the esophagus.

Methods: Patients with anastomotic-stenosis that was diagnosed for the first time following esophageal squamous cell carcinoma resection surgery were randomly assigned to undergo APC combined with SB, APC alone, or SB alone.

Microarray expression profile analysis of long non-coding RNAs in human gastric cardiac adenocarcinoma.

Background/aims: Long noncoding RNAs (lncRNAs) are pervasively transcribed and have been shown to regulate key biological processes that maintain normal cellular functions. Abnormal regulation of these lncRNAs can promote tumorigenesis through resulting aberrant cellular essential functions. however, the roles of lncRNAs played in the development of gastric cardiac adenocarcinoma (GCA) remain unknown.

Microarray expression profile analysis of long non-coding RNAs of advanced stage human gastric cardia adenocarcinoma.

Gastric cardia adenocarcinoma (GCA) is a unique malignant tumor for its characteristics different from gastric and esophageal cancer epidemiologically and pathologically. The incidence of GCA has steadily increased for the last three decades and many patients are diagnosed with advanced stage because of the lack of typical and obvious symptoms at an early stage. To gain insight into the molecular mechanisms of GCA of advanced stage, we investigated the microarray expression profile of long non-coding RNAs of 12 advanced stage GCA patients.

Therapeutic effects of combined oxaliplatin and S-1 in older patients with advanced gastric cardiac adenocarcinoma.

Aim: To evaluate the effects and safety of combination chemotherapy with oxaliplatin (L-OHP) and S-1 (SOX regimen) in older patients with advanced gastric cardiac adenocarcinoma (GCA).

Methods: Seventy patients with advanced GCA were classified according to age into an older group (≥ 75 years) and a control group (< 75 years). The SOX regimen was administered to the two groups as follows: S-1 (40 mg/m² po bid) on days 1 to 14 followed by a 7-d off period, plus L-OHP (65 mg/m² iv) for 2 h on days 1 and 8 of a 21-d cycle.
