Objective To summarize the clinical characteristics and evaluate the feasible treatments of primary breast lymphoma (PBL).Methods The clinical data of 34 PBL patients (age 24-79 years) who were treated in our hospital between April 2006 and December 2013 were reviewed.Of these 34 patients, 18 had stage ⅠE PBL and 16 had stage ⅡE PBL.Pathological types included diffuse large B cell lymphoma (29 patients), anaplastic large cell lymphoma (2 patients), marginal zone lymphoma (2 patients), and mantle cell lymphoma (1 patient).Two patients underwent surgery, four patients received chemotherapy alone, five patients received chemoradiotherapy, fourteen patients underwent surgery plus chemotherapy, and nine patients underwent surgery plus chemoradiotherapy.The 5-year overall survival (OS) and progression-free survival (PFS) rates were determined by the Kaplan-Meier estimator.Results During follow-up, 26 patients were alive without lymphoma and 8 patients had died by the end of follow-up (7 died from lymphoma and 1 died from chemotherapy-related hepatic failure).Among the 6 patients who relapsed, 5(83.3%) had recurrence within the first 2 years of treatment.In particular, 1 patient who had bilateral breast involvement developed left breast relapse after bilateral mastectomy and chemotherapy, 2 patients had bone marrow metastasis, 1 patient had lung and mediastinal lymph node metastases, and 2 had skin relapse.The 5-year OS and PFS rates of all patients were 75% and 75%, respectively.Conclusions Since PBL is a rare malignancy, its overall prognosis is fair and the incidence of local relapse is low with chemotherapy alone or in combination with other treatments.However, further studies on the development of more effective treatments will be required for patients who have failed the existing treatments.

Objective To explore the features of autonomic nerve function in reflux esophagitis (RE) patients, and the role of abnormal function in the pathogenesis of RE. Methods Twenty RE patients (RE group) and 18 healthy controls (HS group) all underwent heart rate variability (HRV) with meal stimulation to test the function of autonomic nerve. At same time, the endoscopic Los Angeles (LA) Classification, RE symptom score, Gastroesophageal reflux disease-health related quality of life (GERD-HRQL), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were evaluated in the RE patients. Of those, 12 RE patients were re-examined the function of autonomic never after 2 to 4 months [mean (3.7±0.8) months] of proton pump inhibitors (PPI) treatment. Results In fasting state, the sympathetic activity was higher in RE group than in HS group, while the parasympathetic activity was lower in HS group (P=0.022 and 0.034). Postprandial, the trend of autonomic functional change was the same in RE group and HS group. Postprandial, the sympathetic activity was negatively correlated with symptom score in RE patients; however, the parasympathetic activity was positively correlated with RE symptom score. The influence of meal on the balance of sympathetic and parasympathetic was negatively correlated with RE symptom score (r=-0.48, P=0.022). The influence of meal on the parasympathetic nerve was positively correlated with RE symptom score and GERD-HRQL score. After PPI treatments, RE symptom score, GERD-HRQL score, SAS score and SDS score were all significantly decreased in RE patients. There was no significant difference in autonomic nerve function before and after PPI treatment. Conclusions There is abnormal autonomic nerve function in RE patients, characterized by higher sympathetic activity and lower parasympathetic activity in fasting state. The autonomic nerve function is correlated with RE symptom score. The abnormal autonomic nerve function may be one of the causes of RE.
