Expression profiling of esophageal squamous cell carcinoma patients treated with definitive chemoradiotherapy: clinical implications

In esophageal squamous cell carcinoma (ESCC), chemoradiotherapy (CRT) has a curative potential even in cases of locally advanced carcinoma. However, only about half of the patients benefit from CRT, and an accurate prediction of sensitivity to CRT is eagerly awaited. Using microarrays, we analyzed gene-expression patterns of pretreatment biopsy specimens from 33 patients with CRT alone including long-term survivors, more than 3 years (14 cases) and short-term survivors, less than 1 year (11 cases). The expression patterns of about 12,600 genes were used to identify genes correlated with survival terms. Fifty-seven genes correlating with short-term survival and 120 genes with long-term survival were identified. The genes involved in the immune response were characteristically upregulated in the long-term survivors, and an immunohistochemical staining confirmed an increased CD8-positive T cell number in the long-term survivors over that in the short-term survivors. In the short-term survivors, on the other hand, increased expression of the genes involved in drug resistance was observed. Our gene list should contribute to the elucidation of the mechanisms of CRT response and contains useful markers for predicting the prognosis of individual ESCC patients treated with CRT alone.     

Prognostic value of TP53 transcriptional activity on p21 and bax in patients with esophageal squamous cell carcinomas treated by definitive chemoradiotherapy

PURPOSE: The aim of this study was to evaluate biologic factors on survival and clinical response after definitive concomitant chemoradiotherapy (CRT) in patients with esophageal squamous cell carcinoma (ESCC). METHODS AND MATERIALS: TP53 protein hyperexpression (immunochemistry [IHC]) and functional assay (FA) of TP53, measuring the ability of TP53 to transactivate p21 and bax reporter systems, were performed in patients with ESCC treated by CRT. The impact of parameters studied on survival and clinical response to CRT was assessed. RESULTS: Thirty-eight patients with ESCC were included. TP53 alterations were detected in 84.2% of cases with FA. All TP53 mutations abolished the transactivation of p21 and bax reporter systems. After CRT, complete response rate was 55.3%. The median survival of the population was 17.5 months. Serum albumin (p = 0.002), weight loss <10% (p = 0.005), and response to treatment (p < 0.001) were significantly linked with survival. TP53 alteration in FA was not significantly predictive of response to CRT (p = 0.132) nor survival (p = 0.154). CONCLUSIONS: Our results suggest that wild-type TP53 in ESCC could be associated with good response to definitive CRT. However, the small rate of ESCC with wild-type TP53 suggests that systematic determination of TP53 status is not appropriate for the management of the ESCC population.

Prognostic impact of RITA expression in patients with anal squamous cell carcinoma treated with chemoradiotherapy

Background

RBP-J interacting and tubulin-associated protein (RITA) has been identified as a negative regulator of the Notch signalling pathway and its deregulation is involved in the pathogenesis of several tumour entities. RITA’s impact on the response of anal squamous cell carcinoma (SCC) to anticancer treatment, however, remains elusive.

Prognostic value of cyclin B1 in patients with esophageal squamous cell carcinoma

BACKGROUND: It has been reported that p53 regulates the G2-M checkpoint transition through cyclin B1, and it has been suggested that p53 plays an important role in the development and progression of various malignancies. The objective of the current study was to clarify the role of the cell cycle regulators, cyclin B1 and p53, in patients with esophageal squamous cell carcinoma (ESCC). METHODS: Tissue samples from 71 patients with ESCC were included in the current study. Expression levels of cyclin B1 and p53 in samples of normal squamous epithelium, dysplasia, and tumor cells from patients with ESCC were analyzed by immunohistochemistry. RESULTS: Several cells in the basement layer of normal epithelium expressed cyclin B1. The number of cyclin B1 positive cells tended to increase as the degree of dysplasia increased from low grade to high grade. More than 20% of tumor cells were cyclin B1 positive in 38 patients (49.3%). Several clinicopathologic parameters, including macroscopic configuration (P < 0.01), pathologic tumor status (P < 0.05), pathologic lymph node status (P < 0.001), pathologic metastatic status (P < 0.01), tumor stage (P < 0.0001), and invasion of lymphatic vessels (P < 0.05), were correlated with the overexpression of cyclin B1. Elevated expression levels of cyclin B1 also were correlated with a poor prognosis in patients with ESCC in univariate analysis (P < 0.0001) and multivariate analysis (P = 0.0135). In contrast, p53 expression exhibited no significant correlation with the level of cyclin B1 expression and was not associated with prognostic parameters in patients with ESCC. CONCLUSIONS: These findings suggest that cyclin B1 is involved in the pathogenesis of carcinoma of the esophagus and that elevated levels of cyclin B1 expression, but not p53 expression, may indicate a poor prognosis for patients with ESCC.     

Prognostic factors in esophageal squamous cell carcinoma patients treated with neoadjuvant chemoradiation therapy

Background

Definitive evaluation of surgical specimens obtained after neoadjuvant chemoradiation therapy (CRT) is important for assessing additional treatment or prognosis in patients with esophageal squamous cell carcinoma (ESCC). In this study, we examined the histological prognostic factors for ESCC patients treated with CRT and determined an appropriate strategy for their evaluation.

Patients and methods

The present study involved 38 consecutive ESCC patients who underwent CRT followed by curative operation. CRT consisted of 5-fluorouracil plus cisplatin and 40 Gy of radiation. We examined histological variables as follows: CRT effect on primary tumor (T-effect: T-effective/T-ineffective), tumor depth (pT), lymph node metastases (pN: pN0/N1), number of lymph node metastases (number-pN), lymphatic invasion, and venous invasion. Univariate and multivariate analyses were performed to examine the independent prognostic factors. Survivals and mode of recurrence were then evaluated according to the independent prognostic factors.

Results

In the univariate analyses, T-effect, pN, number-pN, lymphatic invasion, and venous invasion were found to be prognostic factors with p < 0.01, and pT was a factor with p < 0.05. In the multivariate analysis, pN and T-effect were independent prognostic factors. The five-year survival rate of pN0 patients was more than 75%, even though the T-effect was poor. The 5-year survival rate of patients judged as pN1/T-effective was 50%, whereas all of the pN1/T-ineffective patients died within 2 years with relapse disease.

Conclusion

The evaluation method using both pN status and T-effect is useful for assessing prognosis of ESCC patients treated with neoadjuvant CRT.     

Survival analysis of 80 elderly patients with esophageal squamous cell carcinoma receiving definitive concurrent chemoradiotherapy with S-1

PurposeThis single-center retrospective study aimed to observe survival and prognosis of elderly patients with esophageal cancer receiving radical radiotherapy combined with S1 chemotherapy, and to preliminarily explore whether hematologic indicators or inflammatory indicators before radiotherapy are prognostic factors.Material and methodsWe retrospectively collected data of 80 elderly patients with esophageal cancer who had received radical concurrent chemoradiotherapy from January 2015 to July 2018. The patients were older than 70 years. Radiation therapy was delivered with intensity-modulated irradiation therapy (IMRT) or volumetric modulated arc therapy (VMAT), while the chemotherapy regimen was S1 alone. Toxicities were evaluated in accordance with the criteria of the Radiation Therapy Oncology Group. Baseline hematologic basic nutritional indicators, such as hemoglobin (HGB), albumin (ALB), and prealbumin (PAB), along with inflammatory indicators, such as the ratio of neutrophils to lymphocytes (NLR), the ratio of platelets to lymphocytes (PLR), were collected to preliminarily analyze their relationship with progression and survival.ResultsThe median follow-up time was 39 months (range 30–65 months). The median overall survival and progression-free survival times were 24 and 17 months, respectively. The 1-, 2-, and 3-year overall survival rates were 76.5%, 48.1%, and 31.3%, respectively. The 1-, 2-, and 3-year progression-free survival rates were 57.5%, 37.8%, and 29.4%, respectively. T stage, clinical staging, and lesion region were independent prognostic factors for OS. No significant associations with prognosis were observed either for baseline hematologic or for inflammatory indicators (all P > 0.05). The rates of esophagitis (grade 2 and above) and hematologic toxicity were 60% and 45%, respectively.ConclusionOral S-1 combined with definitive concurrent radiotherapy for elderly patients with esophageal cancer has a significant survival benefit. The toxicities are well tolerated. It seems that prognosis does not correlate with baseline hematologic nutritional indicators and inflammatory indicators.
