Significant association between 53BP1 expression and grade of intraepithelial neoplasia of esophagus: alteration during esophageal carcinogenesis

Conclusions53BP1-NF accumulation increases during cancer progression from LG-IN to HG-IN to CIS to SCC. Detection of 53BP1-NF by immunofluorescence, especially large foci, is a feasible method of estimating DNA instability and the malignant potential of esophageal intraepithelial neoplasia.

We report 2 elderly female patients with LPE who developed squamous cell carcinoma (SCC). Both underwent laparoscopic ischemic gastric preconditioning followed 2 weeks later by 3-field esophagectomy. Final pathological stages were carcinoma-in-situ and pT3N2, respectively. No adjuvant therapy was given. The patient with in-situ cancer has no evidence of recurrence at 24 months. The 2nd patient opted to follow up locally and died 8 months later. LPE should be closely monitored for malignant degeneration. Esophagectomy should be considered when malignancy is detected.

Clinical diagnosis of invasion depth of superficial esophageal squamous cell carcinoma (ESCC) is crucial in determining the precise treatment because the rate of lymph node metastasis increases in proportion of the invasion depth of the carcinoma. According to Japanese guideline for diagnosis and treatment of esophageal cancer, superficial invasions are divided into 5 categories: carcinoma in situ (EP), tumors invade lamina propria mucosa (LPM), lamina muscularis mucosa (MM), the submucosa to a depth of 200 μm or less from the muscularis mucosa (SM1), and the submucosa to a depth more than 200μm (SM2).

Conclusion MTDH is pro-oncogenic factor playing multifaceted and diverse roles in cancer progression. Its association and central role in regulating signaling pathways such a MAPK, wnt/β-catenin, PI3K/AkT, NF-κβ pathways in various cancers shows that it plays a vital role in metastasis. MTDH contribution to chemo and radiotherapy resistance provides a new direction for the development of anticancer therapeutics. Multiple mechanisms converge to promote expression of MTDH in cancers. Further studies are therefore warranted to determine whether the elevated MTDH expression has prognostic value for development...

In addition to their antimicrobial activities, they possess other functions; e.g., cell activation, proliferation, regulation of cytokine/chemokine production, migration, diffe...

Conclusions: To cover 94.5% of ESCC subclinical lesions in the CTVp, a 3-cm margin along the cranial-caudal axis should be added to the primary gross tumor volume as defined by FDG-PET/CT, as well as a cutoff SUVmax value of 2.5. Although preoperative FDG PET/CT images may not reveal lesions directly, the SUVmax and MTV measurements together could predict their presence. Background Esophageal carcinoma often occurs as squamous cell carcinoma (ESCC), a highly aggressive malignancy with a poor prognosis worldwide. The incidence rates of ESCC are particularly high in China (1). Most patients with ESCC have locally adv...

Authors: Roguljic A, Spagnoli G, Juretic A, Sarcevic B, Banovic M, Beketic Oreskovic L Abstract Cancer/testis antigens (CTAs) are a large family of tumor-associated antigens expressed in human tumors of different histological origin, but not in normal tissues, with the exception of the testes and placenta. Numerous immunohistochemical studies have reported associations between CTA expression and a negative estrogen receptor (ER) status in breast tumors, and demonstrated that CTAs are frequently expressed in tumors with higher nuclear grade. The expression of CTAs has not been studied as extensively in ductal carcin...

Abstract Ku80 is an important DNA repair protein. Here, this study sought to investigate clinical impacts of Ku80 expression for patients with superficial esophageal squamous cell carcinoma (ESCC). Immunohistochemical analysis of Ku80 expression was carried out in normal esophageal mucosa, squamous epithelial dysplasia, carcinoma in situ, and superficial ESCC. Its relationships with clinicopathological features and survival of superficial ESCC patients were further clarified. Lentivirus‐mediated RNA interference was used to silence Ku80 gene in ECA109 and KYSE150 cells. Both quantitative real‐time PCR and Western blot ...

This study conducted a retrospective multicenter analysis to investigate the clinicopathological features, optimal therapeutic strategy, and prognosis of spindle cell carcinoma (SpCC) of the esophagus. A total of 71 patients with esophageal SpCC from 3 large cancer centers in China were systematically analyzed. All patients received curative resection, 13 patients received adjuvant radiotherapy and 15 patients received adjuvant combination chemotherapy. Additionally, a total of 1852 patients with typical esophageal SCC (SCC) were selected as controls in this study. SpCC mostly presented as a polypoid appearance (66.2%), ...

CONCLUSIONS: Based on low quality evidence, chemoradiotherapy appears to be at least equivalent to surgery in terms of short-term and long-term survival in people with oesophageal cancer (squamous cell carcinoma type) who are fit for surgery and are responsive to induction chemoradiotherapy. However, there is uncertainty in the comparison of definitive chemoradiotherapy versus surgery for oesophageal cancer (adenocarcinoma type) and we cannot rule out significant benefits or harms of definitive chemoradiotherapy versus surgery. Based on very low quality evidence, the proportion of people with dysphagia at the last follow-u...
