High-dose therapy (HDT) combined with autologous hematopoietic stem cell transplantation (AHSCT) is a standard treatment for relapsed or refractory aggressive lymphoma. However, the role of HDT/AHSCT in the first-line treatment of lymphoma remains controversial, and related issues about its application in different subtypes of lymphoma should be addressed. This article brief-ly reviewed the clinical progress in AHSCT for malignant lymphoma treatment.

Objective To investigate the choice of surgical procedures in the treatment of temporal occipital epidural hematomas.Methods From March 2006 to March 2011,176 cases with acute temporal occipital epidural hematomas were treated in our hospital.Their clinical data including preoperative Glasgow Coma Sale (GCS),pupil size,hematoma volume,cerebrospinal fluid leakage,time between injury and operation,cerebral midline shift on CT,and brain beat and brain swelling in the operation were retrospectively analyzed.Results There were significant differences in the choice of surgical treatment and prognosis of temporal occipital epidural hematoma according to the preoperative GCS score,pupillary changes,hematoma volume,length of time before surgery,shift of cerebral midline structures,and brain beat and brain swelling in the operation.Conclusion Appropriate surgical procedures selected according to their preoperative and intraoperative conditions is of significant importance for sound prognosis of the patients with acute temporal occipital epidural hematoma.

Objective:To explore the classification and the choice of surgical approach for tentorial meningiomas. Methods: 56 patients with tentorial meningiomas operated on between 1992 and 2002 were retrospectively analysed. According to Gkalp , there were 28 cases with medial tumor,17 cases with lateral tumor,11 cases with falcotentorial tumor. The tumors developing mainly supratentorial were approached from modified pteronal, subtemporal, temporooccipital or occipital craniotomy. For tumors developing mainly in the posterior cranial fossa, suboccipital craniectomy or combined occipital- suboccipital craniectomy was performed. The tumors developing both supratentorial and infratentorial the subtemporal-presigmoidal craniotomy were approached . Results: Total removal was achieved in 53 cases and partial removal in 3 cases. Two cases died of severe postoperative complications. The mortality rate was 3.6%. Five had additional neurological deficits postoperatively. Recurrences occurred in 6 cases. Conclusion: Surgical approach for tentorial meningiomas must be individualized for each case. The operators must master well about microanatomy of the tentorium and its specifically regional structures and expertly use microsurgical techniques for obtaining successful surgery and good outcome.

Objective:To discuss the diagnosis, treatment and outcome of patients with gliomatosis cerebri (GC). Methods:Retrospectively reviewed the clinical manifestations and radiological appearances of 6 patients with GC, which were diagnosed in our hospital between 1993 and 2003. We employed surgical treatment in three patients, stereotactic biopsy in two, and the other one received both biopsy and surgery. Results: The lesions of GC infiltrated more than two lobes in brain. CT studies showed diffuse hypodensity changes and enhancement was absent in four patients. MRI examinations revealed isointense or hypointense regions on T1WI, and uniformly high signal on T2WI. MRI also disclosed structural enlargement. All patients received radiotherapy after surgery and three patients underwent chemotherapy additionally. Five patients died during follow up with average course of 16.4 months. Conclusion:MRI examination is valuable in the diagnosis and the prognosis of GC is poor.

Objective To develop a simple and effective method for monitoring cortical ischemia after temporary occlusion of the parent arteries during anterior circulation intracranial aneurysm surgery. Methods Fifty-two patients with anterior circulation aneurysm (58 aneurysms) received craniotomy from April to November 2008, and at the same time,cortical electroencephalograpby (EEG) and scalp EEG were monitored during the surgery.According to the international 10/20 electrode placement system, scalp electrodes were placed on O1, O2, P3, P4, T5, and T6 for monitoring the changes in the depth of anesthesia. A cortical strip electrode was placed on the cortical surface supplied by the artery that was possibly blocked during the operation, which was used to monitor the possible cortical ischemia. For patients who had cortical EEG suppression after the temporary occlusion of the parent arteries Were compared with the changes of scalp EEG. Whether there were ischemic events in the corresponding supply territory after vascular occlusion were observed after surgery. Results Of the 58 aneurysms, 40 aneurysms and 41 major arteries were occluded temporarily. After being occluded temporarily in 19 arteries of 18 patients, cortical EEG changed significantly,while scalp EEG did not change significantly. Only 9 patients had ischemic events in the corresponding supply territories after the occlusion in the cortical EEG significant change group. The changes in the depth of anesthesia had the consistent impact on cortical and scalp EEG. Conelusions Simultaneous monitoring of cortical and scalp EEG is a simple and effective method for monitoring cortical ischemia during anterior circulation intracranial aneurysm surgery, and may effectively identify the effect of anesthesia on EEG.

Objective To investigate the relationship of lymph node metastasis rate (LNR) with prognosis of esophageal squamous cell carcinoma after radical resection and postoperative adjuvant chemotherapy.Methods The retrospective case-control study was conducted.The clinicopathological data of 121 patients who underwent radical resection of esophageal squamous cell carcinoma in the Peking University Cancer Hospital from January 2012 to September 2016 were collected.There were 105 males and 16 females,aged from 42 to 76 years,with a median age of 58 years.All patients underwent radical resection of esophageal cancer with at least two-field lymph nodes dissection.Some patients underwent corresponding chemotherapy and radiotherapy.The thoracic and abdominal lymph nodes were grouped according to the 7th edition standard of Americau Joint Committee on Cancer (AJCC).The lymph nodes dissected were labeled in groups,and all the lymph nodes were examined by pathology test.Observation indicators:(1) follow-up;(2) effects of LNR on prognosis of patients in different AJCC N staging;(3) relationship between LNR and postoperative adjuvant chemotherapy.Follow-up was conducted by outpatient examination,telephone interview and hospital statistical office to detect postoperative survival of patients up to February 2017.The disease-free survival time was from surgery date to date of confirmation of tumor recurrence,and the overall survival time was from surgery date to death of the patient or the last follow-up date.Measurement data with skewed distribution were expressed by M (range).The Kaplan-Meier method was used to calculate the survival rate and draw the survival curve.The Log-rank test was used for survival analysis.Results (1) Follow-up:121 patients were followed up for 3.0-94.2 months,with a median follow-up time of 27.1 months.During the follow-up,98 of 121 patients had tumor recurrence and metastasis (including 64 deaths),22 had no metastasis,and 1 had unknown tumor metastasis.The mean overall survival time of patients was 30.8 months.The 1-,3-,5-year disease-free survival rates were 47.1％,20.3％,and 5.9％,respectively.The 1-,3-,5-year overall survival rates were 93.1％,48.7％,and 35.3％,respectively.(2) Effects of LNR on prognosis of patients in different AJCC N staging:of 121 patients,46 were in N0 stage,42 were in N1 stage,28 were in N2 stage,and 5 were in N3 stage.Of 42 patients in N1 stage,35 with 0 ＜ LNR ≤ 0.15 had a disease-free survival time of 12.2 months (range,1.2-82.3 months),and 7 with LNR ＞ 0.15 had a disease-free survival time of 6.9 months (range,2.1-23.1 months);the difference between the two groups was statistically significant (x2 =3.888,P＜0.05).Of the 28 patients in N2 stage,12 with 0 ＜ LNR ≤ 0.15 had a disease-free survival time of 8.5 months (range,1.2-38.8 months),and 16 with LNR ＞ 0.15 had a disease-free survival time of 4.4 months (range,1.0-52.7 months);the difference was not statistically significant (x2 =0.007,P＞0.05).Forty-six patients in N0 stage were detected no lymph node metastasis,and only 5 cases were in N3 stage,with no analysis.(3) Relationship between LNR and postoperative adjuvant chemotherapy:of the 121 patients,56 underwent postoperative adjuvant chemotherapy,which was mainly constituted by pactitaxel,platinum,and 5-fluorouracilbased regimens,58 didn't undergo postoperative adjuvant chemotherapy,and 7 had unknown data of postoperative adjuvant chemotherapy.Of 121 patients,46 had LNR =0,47 had 0 ＜ LNR ≤ 0.15,28 had LNR ＞ 0.15.Of the 46 patients with LNR =0,17 who underwent postoperative adjuvant chemotherapy had a disease-free survival time of 8.1 months (range,3.9-66.7 months) and a overall survival time of 34.0 months (range,4.7-76.0 months);29 who didn't undergo postoperative adjuvant chemotherapy had a disease-free survival time of 18.8 months (range,1.6-53.2 months),and a overall survival time of 48.6 months (range,8.3-94.2 months);there was no significant difference in the disease-free survival time and overall survival time between the two groups (x2=0.311,0.858,P＞0.05).Of the 47 patients with 0 ＜ LNR ≤ 0.15,27 who underwent postoperative adjuvant chemotherapy had a disease-free survival time of 13.3 months (range,5.0-82.3 months),and a overall survival time of 53.1 months (range,5.7-82.3 months);20 without postoperative adjuvant chemotherapy had a disease-free survival time of 8.4 months (range,1.2-39.2 months),and a overall survival time of 26.5 months (range,5.9-52.6 months).There were significant differences in the disease-free survival time and overall survival time between the two groups (x2 =10.322,4.971,P＜0.05).Of the 28 patients with LNR ＞ 0.15 (7 had unknown data of postoperative adjuvant chemotherapy),12 who underwent adjuvant chemotherapy had a diseasefree survival time of 10.3 months (range,2.9-52.7 months),and a overall survival time of 29.5 months (range,11.2-58.5 months);9 without postoperative adjuvant chemotherapy had a disease-free survival time of 2.9 months (range,1.4-35.7 months),and a overall survival time of 14.5 months (range,3.0-62.3 months);there was a significant difference in the disease-free survival time between the two groups (x2 =6.687,P＜0.05),and no significant difference in the overall survival time between the two groups (x2=2.938,P＞ 0.05).Conclusions LNR can be used as a supplementation of AJCC N staging system.In patients with 0＜ LNR ≤ 0.15,postoperative adjuvant chemotherapy can improve disease-free survival time and overall survival time.
