PURPOSE: Randomized trials showing a clear survival benefit of intensity-modulated radiotherapy (IMRT) over 3-dimensional conformal radiotherapy (3D-CRT) in the treatment of lung cancer are lacking. This study compared the survival rates of patients with stage III non-small cell lung cancer who were treated with either 3D-CRT or IMRT and analyzed the prognostic factors for survival. METHODS: From January 2008 to July 2015, 19 patients were treated with IMRT and 30 were treated with 3D-CRT in our institution...

A 67-year-old male was diagnosed with advanced esophageal cancer. A computed tomography scan showed multiple intra-abdominal lymphadenopathies. Because the tumor was thought to be unresectable, we initiated chemotherapy. Twelve months later, the patient was admitted to our hospital because of hematemesis. Gastroduodenoscopy revealed oozing bleeding from the esophageal tumor. Hemostasis was not achieved with conservative treatment, and frequent blood transfusions were required. Endoscopic hemostasis was difficult to achieve because of the malignant esophageal stenosis...

Recurrent esophago-gastric junction adenocarcinoma is not a rare event and its correct management is still debated. Many approaches for the treatment of these patients exist, but only few studies compare the different techniques. Most of the studies are retrospectives series and describe the experiences of single institutions in the treatment of recurrent esophageal and esophago-gastric junction cancers. Nowadays surgery is still the main and only curative treatment. Other alternative palliative therapies could be endoscopic stent placement and balloon dilation, photodynamic therapy, thermal tumor ablation (laser photoablation and Argon plasma coagulation), radiation therapy and brachytherapy, and chemotherapy...

Aerobic glycolysis is one of the emerging hallmarks of cancer cells. In this study, we investigated the relationship between blocking mitochondrial pyruvate carrier (MPC) with MPC blocker UK5099 and the metabolic alteration as well as aggressive features of esophageal squamous carcinoma. It was found that blocking pyruvate transportation into mitochondria attenuated mitochondrial oxidative phosphorylation (OXPHOS) and triggered aerobic glycolysis, a feature of Warburg effect. In addition, the HIF-1α expression and ROS production were also activated upon UK5099 application...

Esophageal squamous cell carcinoma (ESCC) has a high morbidity in China and its treatment depends greatly on adjuvant chemotherapy. However, DNA damage repair in cancer cells severely affects the outcome of treatment. This study investigated the potential mechanism regarding mediator of DNA-damage checkpoint 1 (MDC1) and minichromosome maintenance proteins (MCMs) during DNA damage in ESCC. Recombinant vectors of MDC1 and MCMs with tags were constructed and transfected into human ESCC cell line TE-1. Immunoprecipitation and mass spectrometry were performed to screen the MCMs interacting with MDC1, and direct interaction was confirmed by glutathione S-transferase (GST) pull-down assay in vitro...

Esophageal cancer (EC) is an aggressive tumor that represents the 6th most common cause of cancer death worldwide. The estimated incidence in Spain is 2090 cases/year. Two main pathological subtypes exist, squamous cell carcinoma and adenocarcinoma. The main differences between them are localization and underlying factors which are the principal cause of the recent incidence changes observed in west countries. Staging techniques and treatment options which combine surgery, chemotherapy and radiotherapy, reflected the high complexity of the EC management...

There is a well-established link between cancer and venous thromboembolism (VTE), and patients receiving chemotherapy for esophageal or gastric cancer appear at high risk of developing VTE. The incidence of VTE in the neoadjuvant setting in these patients is poorly understood, as is the role for thromboprophylaxis during neoadjuvant chemotherapy. A PubMed search was conducted using a combination of terms including; esophageal & gastric cancer, deep venous thrombosis (DVT), VTE, neoadjuvant, chemotherapy and chemoradiotherapy...

Purpose: Platinum derivatives, such as cisplatin (DDP), carboplatin and oxaliplatin, are widely used components of modern cancer chemotherapy including esophageal squamous cell cancer (ESCC). However, their roles are limited by the impact of intrinsic/acquired resistance mechanisms on tumor responses. Recent studies have shown that the mammalian copper transporters CTR1, ATP7A and ATP7B are involved in cisplatin-resistance to some cancers. Methods: The cytotoxicities of DDP in different cell lines were determined using the MTT assay...

The predominant histological types of esophageal cancer are adenocarcinoma and squamous cell carcinoma. Since these two histological types present as different diseases in terms of their epidemiology, pathologenesis, and tumor biology, separate therapeutic approaches should be developed against each type. While surgical resection remains the dominant therapeutic intervention for patients with operable esophageal squamous cell carcinoma (ESCC), their high rates of tumor recurrence have prompted investigation of multimodality therapies that combine surgery with chemotherapy, radiotherapy, and chemoradiotherapy...

Esophageal cancer is a serious malignancy often treated with multimodal interventions and complex surgical resection. As treatment moves to centers of excellence with emphasis on enhanced recovery approaches, the role of the physiotherapist has expanded. The aim of this review is to discuss the rationale behind both the evolving prehabilitative role of the physiotherapist and more established postoperative interventions for patients with esophageal cancer. While a weak association between preoperative cardiopulmonary fitness and post-esophagectomy outcome is reported, cardiotoxicity during neoadjuvant chemotherapy and/or radiotherapy may heighten postoperative risk...

Given the paucity of esophageal small cell carcinoma (SCC) cases, there are few large studies evaluating this disease. In this study, the National Cancer Data Base (NCDB) was utilized to analyze the clinical features, treatment, and survival of patients with esophageal SCC in a large, population-based dataset. We selected patients diagnosed with esophageal SCC from 1998 to 2011. Patients were identified as having no treatment, chemotherapy alone, radiation ± sequential chemotherapy, concurrent chemoradiation, and esophagectomy ± chemotherapy and/or radiation...

BACKGROUND: Human DNA polymerase β (polβ) is a small monomeric protein that is essential for short-patch base excision repair. It plays an important role in regulating the sensitivity of tumor cells to chemotherapy. METHODS: We evaluated the mutation of polβ in a larger cohort of esophageal cancer (EC) patients by RT-PCR and sequencing analysis. The function of the mutation was evaluated by CCK-8, in vivo tumor growth, and flow cytometry assays. RESULTS: There are 229 patients with the polβ mutation, 18 patients with A613T mutation, 12 patients with G462T mutation among 538 ECs...
