Changes of T Lymphocyte Subsets in Peripheral Blood of Patients with Intermediate and Advanced Cervical Cancer before and after Nimotuzumab Combined with Chemoradiotherapy.

INTRODUCTION: Cervical cancer (CC) is the main malignant tumor of gynecology with high mortality. This study aimed to explore the changes of T lymphocyte subsets in the peripheral blood of patients with intermediate and advanced CC (IACC) treated with nimotuzumab (Nimo) combined with chemoradiotherapy (CRT). METHODS: Peripheral blood was extracted before and after treatment, and patients were randomly divided into the CRT group (N = 68) or the Nimo + CRT group (N = 68). The levels of tumor markers squamous cell carcinoma antigen (SCCA), carbohydrate antigen 125 (CA125), and carcinoembryonic antigen (CEA), tumor indexes leptin and insulin-like growth factor-2 (IGF2), and key secretory factors (interferon γ/tumor necrosis factor α/interleukin (IL)-4/IL-13) of Th1 and Th2 cells in the serum were detected. The levels of T lymphocyte subsets CD3+, CD4+, CD8+, and CD4+/CD8+ and the levels of Th1/Th2 and Th17/Treg in CD4+ cell subsets were determined by flow cytometry. The objective remission rate, progression-free survival (PFS), and overall survival (OS) of patients were analyzed, and Kaplan-Meier curves were drawn to show the prognosis of patients. RESULTS: After treatment, the levels of SCCA, CA125, CEA, leptin, and IGF2 in the serum of patients with IACC were decreased, the level of Th1/Th2 was increased, and the Th17/Treg level was decreased. The treatment effect of Nimo + CRT was more significant than that of CRT alone. Survival curve analysis showed that Nimo + CRT could prolong PFS and OS in patients with IACC. In addition, the follow-up results of patients showed that Nimo did not increase the incidence and severity of adverse reactions caused by CRT. CONCLUSION: Nimo combined with CRT can protect the immune function of patients, improve the effective rate, and prolong the survival rate of patients with IACC.

Nomogram for predicting the survival of patients with small cell carcinoma of the esophagus: A population study based on the surveillance, epidemiology, and end results database.

ABSTRACT: This study aims to establish an effective prognostic nomogram for small cell carcinoma of the esophagus (SCCE).A total of 552 patients with SCCE from 1975 to 2016 were extracted from the surveillance, epidemiology, and end results (SEER) database. A Cox proportional hazard regression model was used to analyze the prognostic factors of patients, and a nomogram was constructed. The nomogram was then validated internally by using a consistency index (C-index) and a correction curve to evaluate its predictive value.The Cox proportional hazard regression model showed that age, stage, surgery, primary site, radiotherapy, and chemotherapy were the prognostic factors of SCCE (P < .1), and they were used to construct the nomogram. The C-index of the nomogram for predicting survival was 0.749 (95% confidence interval [CI] = 0.722-0.776). The data were randomly divided into a modeling group and a validation group based on 7:3 for internal validation. The C-indices of the modeling and validation groups were 0.753 and 0.725, respectively, and they were close to 0.749. The calibration curves exhibited good consistency between the predicted and actual survival rates.The nomogram of the survival and prognosis of patients with SCCE in this study had a good predictive value and could provide clinicians with accurate and practical predictive tools. It could also be used to facilitate a rapid and accurate assessment of patients' survival and prognosis on an individual basis.

Brain metastases from esophageal cancer: A case report.

INTRODUCTION: At present, there is no uniform consensus on the treatment of brain metastases from esophageal cancer. The studies on the treatment of brain metastases from esophageal cancer by radiotherapy combined with temozolomide (TMZ) are even rarer. PATIENT CONCERNS: A 69-year-old woman was admitted to our hospital for brain metastases from esophageal cancer after thoracic irradiation. DIAGNOSES: Magnetic resonance imaging of the head showed a round, heterogeneous metastatic tumor in the left parietal lobe. Brain magnetic resonance imaging showed edema around brain metastasesInterventions: After radiotherapy plus TMZ in this patient's head, the brain metastatic tumor was significantly decreased. OUTCOMES: At the end of radiotherapy, and 1 and 2 months after the end of radiotherapy, the metastatic tumor continued to shrink, and no obvious side effects were observed. LESSONS: This study suggests that radiotherapy plus TMZ might be a feasible option for brain metastases from esophageal cancer.
