Objective: Predicting outcome in patients with primary intracerebral haemorrhage (ICH) in the acute stage can provide information to determine the best therapeutic and rehabilitation strategies. We prospectively investigated the predictive value of the functional diffusion map (fDM) in the acute stage of ICH. Methods: 47 patients with ICH were enrolled for clinical evaluation and MRI within 24 h of symptom onset and 5 days after ICH. Functional diffusion mapping prospectively monitored the apparent diffusion coefficient (ADC) maps of perihaematomal oedema. Consequently, the change in perihaematomal oedema was classified into three categories: increased, decreased, or no significant change. Clinical outcomes were evaluated 6 months after ICH according to the modified Rankin Scale. Correlation between clinical outcome and the fDMs was performed. Results: Among the clinical variables, thalamic haematoma, serum glucose level and National Institutes of Health Stroke Scale scores were significantly different between the good- and poor-outcome groups. The percentage of oedematous tissue undergoing significant change between baseline and Day 5 was also significantly different between the groups. Conclusion: fDMs allow for spatial voxel-by-voxel tracking of changes in ADC values. It may be feasible to use fDMs to predict the functional outcome of patients with ICH during the acute stage. Advances in knowledge: The use of fDMs for stroke study is demonstrated. fDMs may be more suitable to reflect the pathophysiological heterogeneity within oedemas and may facilitate another thinking process for imaging study of stroke and other neurological diseases.

Primary small cell carcinoma of esophagus (SCCE) is a relatively rare and highly aggressive tumor characterized by early dissemination and poor prognosis. The optimal treatment has not yet been established, and the role of surgery has remained controversial. Most of the limited diseases were treated conventionally by surgery, but the five-year survival rate was still very low. This retrospective study was designed to investigate the clinical characteristics, treatment, and prognostic factors of limited disease SCCE. Clinical data of 40 SCCE patients with clinically limited disease who received transthoracic esophagectomy with lymphadenectomy at the Cancer Hospital of Shantou University Medical College from November 1990 to December 2009 were reviewed to summarize the clinical characteristics and treatment impacted on the survival. Twenty-five cases of the 40 patients were treated with surgery alone, eight cases were treated with surgery + postoperative chemotherapy, four cases were treated with surgery + postoperative radiotherapy, and the other three were treated with surgery + postoperative radiochemotherapy. The Kaplan-Meier and log-rank methods were used to estimate and compare survival rates. Cox's hazard regression model was used to identify the prognostic factors with the entry factors of gender, age (≤60 years versus >60 years), length of the primary lesion (≤5 cm versus >5 cm), location of the primary lesion, macroscopic tumor type, pT, pN, pTNM stage, operation (radical/palliative), and chemotherapy (yes/no). The mean follow-up duration of this series was 24.7 months (1-121 months). Thirty-four patients died of the disease during the follow-up, five were still alive, and one was lost of follow-up. The median survival time of the 40 patients was 13.0 months (95% confidence interval 4.7-21.3), and the 6-, 12-, 24-, 36-, and 60-month overall survival rates (OS) were 77.5%, 56.4%, 28.9%, 23.7%, 10.5%, respectively. In univariate analysis, age (≤60 years versus >60 years) ( P= 0.049), operation (radical/palliative) ( P= 0.008), and chemotherapy (yes/no) ( P= 0.013) significantly influenced the OS of the SCCE patients. In multivariate analysis, operation ( P= 0.015) and chemotherapy ( P= 0.031) were independent prognostic factors. The patients who received radical surgery and postoperative chemotherapy had relatively better survival. Surgical resection combined with chemotherapy should be recommended to patients with limited disease SCCE. [ABSTRACT FROM AUTHOR]

Esophageal squamous cell carcinoma (ESCC) in the young patients is comparatively rare and has not been well studied. We analyzed the clinical and survival data of 127 ESCC patients <40 years at a single high-volume center and compared with those of 4109 ESCC patients ≥40 years who underwent surgery within the same period in this study. The average age was 36.5 ± 0.2 years for the young patient group, with the youngest aged 26 years. Young patients had a higher rate of family history, longer tumors, and a more advanced pT category than their older counterparts. Moreover, more patients in the young group underwent incomplete resection (19.7% vs. 8.9%, P  < 0.001) and adjuvant therapy (40.9% vs. 30.8%, P  = 0.015). The overall survival (OS) and cancer-specific survival (CSS) between patients <40 years and patients ≥40 years were not significant in the entire group. In the subgroup analysis, the OS and CSS rates for patients <40 years were significantly worse than patients ≥40 years in subgroups of pTNM stage III and incomplete resections. In conclusions, young patients with ESCC were more likely to have family history and present with advanced disease. The survival for young patients with ESCC was poorer than their older counterparts in patients with later stage diseases. [ABSTRACT FROM AUTHOR]
