头颈部良性神经源性肿瘤1H MRS的表现特点

目的：探讨头颈部良性神经源性肿瘤在单体素^1H MRS上的表现特点。材料和方法：共收集经单体素。HMRS检查，并经手术病理证实的头颈部神经源性肿瘤14例（神经鞘瘤11例，神经纤维瘤2例，颈动脉体瘤1例）。采用点分析波谱法（PRESS：TE=144ms，14例）和激励回波法（STEAM：TE=30ms，11例）进行。HMRS空间定位，以胆碱和脂质代谢物为标准评价所有肿瘤。波谱图上，胆碱和脂质分别在3．2ppm和0．9—1．4ppm区域识别。结果：采用PRESS后，14例神经源性肿瘤中检测出胆碱代谢物者11例，检出脂质代谢物者6例。胆碱和脂质代谢物同时检出者5例，仅检出胆碱者6例，仅检出脂质者1例，胆碱和脂质均未检出者2例。采用STEAM后，11例肿瘤中检出胆碱代谢物和脂质者分别为3例和8例。结论：头颈部良性神经源性肿瘤的单体素。HMRS表现具有多样性，多数肿瘤以长TEPRESS上胆碱峰的显示为特点，长TEPRESS能较STEAM更好地检出良性神经源性肿瘤内的胆碱代谢物。     

Testicular tumors

Germ cell tumors of the testes represent a unique paradigm of diseases which can be cured even in extremely advanced phase. Unfortunately, this makes them unique among adult solid tumors. Seminoma and non seminoma are relatively rare with approximatively 25,000 patients in Europe per year, but numbers are increasing world wide. Different strategies are needed depending on stage and prognostic scores. Seminoma is extremely sensitive to radiation therapy and chemotherapy, while all germ cell tumors show a very good response to chemotherapy. Clinical stage I seminoma is currently treated with radiation, single course carboplatin or surveillance policy. Clinical stage I non seminoma can also be approached with different strategies such as retroperitoneal lymph node dissection, observation or one-two courses of standard chemotherapy. Stage II seminoma may be treated with either radiation or chemotherapy, while for all advanced stages chemotherapy is mandatory. Since the mid-eighties PEB (Cisplatin, Etoposide and Bleomycin) is the regimen of choice and no other schedule has proved superior in terms of efficacy. Surgery on the residual disease is crucial to the whole strategy and should be performed or attempted in all cases. Consequently, the correct treatment strategy for these tumors does not depend only on the ability of a single physician, but on a skilled team specialized in this particular tumor. Second line therapies (VeIP, PEI, TIP) can cure 25%–40% of patients, but improved strategies for resistant tumors are desperately needed. High-dose chemotherapy has shown very good results in some studies while being less impressive in others. In any case, it should remain an option for relapsing patients and could be used in some cases of upfront chemotherapy in patients with slow marker decline, but this should only be considered in referring centers.     

Aesthetic aspects in reconstructive microsurgery

The reconstruction of a part of the body that has lost or inhibited function has been the most important aspect of reconstructive surgery in the past. Because of the existence of better techniques and the patient's wish for social reintegration, the plastic surgeon today is forced to consider the aesthetic results of his work more than in the past. Sometimes microsurgical procedures in reconstructive surgery are the only chance for the patient to be healed or palliated. Experience with more than 350 free tissue transfers gave us the opportunity to estimate the value of a donor flap with respect to the requirements of the receiving site. To satisfy the high aesthetic demands in these cases, it was necessary for the right place and shape the flap to fit as closely as possible, even if further corrections were necessary to achieve a satisfactory result. The transfer of latissimus dorsi and radial forearm flaps to the face and lower leg is discussed in cases of tumorus diseases and severe injuries of young and old patients.Presented to the IXth Congress of the International Society of Aesthetic Plastic Surgery, New York, October 13, 1987     

肿瘤干细胞是中医药防治恶性肿瘤复发转移的可能靶点

肿瘤的复发转移是导致恶性肿瘤治疗失败的主要原因，寻求防治恶性肿瘤复发及转移的靶点是目前肿瘤研究的重点。研究表明肿瘤干细胞在肿瘤的复发转移中扮演着极其重要的角色，目前尚没有靶向调控肿瘤干细胞功能的成熟的方法。中医药在防治恶性肿瘤复发转移中有较好的疗效，为了更好地发挥这种疗效，并深入探讨其作用机制，应对中医药调控肿瘤干细胞功能进行相关研究，找出中医药作用的最终作用靶点。     

腮腺良性和恶性多形性腺瘤的超声研究

目的研究腮腺良性和恶性多形性腺瘤的超声特点,为临床医师诊治提供有效依据。方法选取腮腺良性多形性腺瘤患者79例和恶性多形性腺瘤患者15例,对其肿块的大小、硬度、内部回声、彩色多普勒血流显像(CDFI)特点结合病理学诊断进行对照研究。结果恶性多形性腺瘤的声像图特点与良性多形性腺瘤相似,但其肿瘤相对较大,质地更硬,内部回声分布更紊乱。不同性质的肿瘤的大小和质地有显著性差异,(P<0.01)。结论多形性腺瘤的超声诊断主要依据二维图像之特点。当多形性腺瘤大于3.0 cm,硬度较硬,内部回声分布不均多提示恶性。     

Curative Laparoscopic Resection for Pancreatic Neoplasms: A Critical Analysis from a Single Institution

Laparoscopic pancreatic surgery (LPS) has seen significant development but much of the knowledge refers to small and benign pancreatic tumors. This study aims to evaluate the feasibility, safety, and long-term outcome of the laparoscopic approach in patients with benign, premalignant, and overt malignant lesions of the pancreas. This study, currently, is the largest single center experience worldwide. One hundred twenty-three consecutive patients underwent laparoscopic pancreatic surgery from April 1998 to April 2007, 20 patients with cysts or pseudocysts for acute and chronic pancreatitis, laparoscopic pancreatic drainage was performed, and were excluded from the analysis. The 103 patients were divided based on preoperative diagnosis: group I, inflammatory tumors for chronic pancreatitis (eight patients); group II, cystic pancreatic neoplasms (29 patients); group III, intraductal papillary mucinous neoplasms (10 patients); group IV, neuroendocrine pancreatic tumors (NETs) (43 patients); and group V ductal adenocarcinoma (13 patients). The median tumor size was 5.3 cm. Pathologic data include R ₀ or R ₁ resection (transection margins on the specimen were inked). Perioperative data, postoperative complications, and resection modalities were compared using statistical analysis. Long-term outcomes were analysed by tumor recurrence and patient survival. The overall conversion rate was 7%. Laparoscopic distal pancreatic resection was performed in 82 patients (79.6%). Laparoscopic spleen-preserving distal pancreatectomy (Lap SPDP) was performed in 52 patients (63.7%), but with splenic vessels preservation in 22% and without splenic vessels preservation in 41.5%. Laparoscopic en-bloc splenopancreatectomy (Lap SxDP) was performed in 30 patients (36.6%) and laparoscopic enucleation (Lap En) in 20 patients (19.4%). There was no mortality. The overall complication rate was 25.2, 16.7, and 40% after Lap SPDP, Lap SxDP, and Lap En, respectively. The overall morbidity rate was significantly higher (p > 0.05) in the group of Lap SPDP without splenic vessels preservation comparing with Lap SPDP with splenic vessels preservation because of the occurrence of splenic complications (20.6%). The overall pancreatic fistulas was 7.7, 10, and 35% after Lap SPDP, Lap SxDP, and Lap En, respectively; the severity of fistula was significantly higher in the Lap En group (p > 0.05). The mean hospital stay was within 1 week in all groups, except in the group of ductal adenocarcinoma, which is 8 days. In this series, 27 patients (26.2%) had malignant disease. R ₀ resection was achieved in 90% of ductal adenocarcinoma and 100% for other malignant tumors. The median survival for ductal adenocarcinoma patients was 14 months. This series demonstrates that LPS is feasible and safe in benign-appearing and malignant lesions of the pancreas.     

107例胃肠间质瘤的病理学分析及临床诊治

目的总结胃肠间质瘤(GIST)的临床病理和免疫组织化学(免疫组化)特征,并评价预后。方法对1996年4月至2005年10月收治的107例GIST患者的临床资料进行回顾性分析。结果107例GIST病例中,73例(68.2%)为胃间质瘤,其他为小肠、结肠和系膜、网膜及后腹膜间质瘤;肿瘤直径0.7～20cm。CD117和vimentin阳性率100%,CD34阳性率83.2%。107例患者均接受手术治疗,联合脏器切除14例次。总随访率83.2%,平均随访24.5个月。14例(13.1%)发现复发或转移,其中4例为GIST中度恶性风险者。10例为高度恶性风险者;死亡4例。结论GIST的确诊主要依靠病理及免疫组化,CD117是诊断GIST的重要标记物,手术完整切除肿瘤效果满意,恶性GIST宜行较大范围的切除术。必要时须行联合脏器切除。     

Turcot syndrome confirmed with molecular analysis

Turcot syndrome is clinically characterized by the occurrence of primary brain tumor and colorectal tumor and has, in previous reports, been shown associated with germline mutations in the genes APC , MLH1 , MHS6 , and PMS2 . To date, only few families have been documented by molecular analysis. We report two new families with Turcot syndrome to illustrate and review its characteristics and facilitate diagnosis. Molecular analysis revealed two germline mutations, one in the MLH1 gene and one in MSH2 . The latter has never been describe in the literature. Personal and familial relevant anamnestic data from patients with glioma might aid in the diagnosis of genetic disorders. The subsequent molecular characterization may contribute to the appropriate care of affected patients and asymptomatic gene carriers.
