精准肝切除术治疗原发性肝癌的临床效果分析

目的:探讨腹腔镜精准肝切除术的特点及效果,为普外科手术提供参考。方法:选取2011年10月-2013年7月我院收治的92例原发性肝癌患者的临床资料进行回顾分析。根据手术方式不同,将病例分为常规肝切除组和精准肝切除组,每组46例。观察并比较两组患者的评均术中出血量、手术时间、住院时间、手术前后的肝功能指标变化、并发症的发生率、肿瘤局部复发率及远期转移率等。结果:与常规肝切除组相比较,精准肝切除组患者的平均术中出血量少、住院时间短、术后并发症的发生率及肿瘤复发转移率低,但手术时间较长,组间比较差异显著,具有统计学意义(P0.05)。与手术前比较,两组患者手术后的血清TBIL、ALT及AST含量降低,ALB升高,精准肝切除组患者各项指标的变化程度更显著,肝功能优于常规肝切除组,组内及组间比较差异具有统计学意义(P0.05)。结论:精准肝切除术对于原发性肝癌的治疗具有良好临床的效果,不仅能够彻底清除病灶,而且降低了术后肝衰竭等并发症的发生率,值得推广应用。     

The Outcome of Ipsilateral Hemihepatectomy in Mucin-Producing Bile Duct Tumors

Background

Mucin-producing bile duct tumors (MPBTs) are unusual, and we present our experience with nine surgically proven cases.

Methods

Between November 2002 and November 2012, 9 patients with surgically proven MPBTs (including history of relevant hepatobiliary surgery in 6 patients) were encountered. Their clinical, imaging, and surgical findings were reviewed.

Results

The most common symptom is intermittent jaundice, which occurs in seven patients. The diagnostic specificity was 77.8% by preoperative Magnetic Resonance Cholangiopancreatography (MRCP). All the patients underwent ipsilateral hemihepatectomy or remnant hemihepatectomy, accompanied caudate lobectomy in one case and concomitant Roux-en-Y choledochojejunostomy in four cases. Postoperative course was uneventful. One patient, who had intra-abdominal recurrence 59 months after surgery, was received reoperation without recurrence at the last follow-up. The remaining eight patients were alive without disease recurrence.

Conclusion

Based on our follow up of 9 cases that were surgically treated for MPBTs, we conclude that ipsilateral hemihepatectomy is a safe surgical procedure with an observed recurrence risk of 11.1% and all long-term survival.     

Laparoscopic colon surgery: our results

Formerly, the laparoscopic surgery was accepted as a method of choice for benign diseases, and for palliative operations in progressive stages of malignant diseases of the colon. Today, the laparoscopic surgery of the colon has been also adopted in treating malignant diseases. The first laparoscopic colon resection was performed in our Clinic on December 12, 2002, and 114 patients have been successfully operated until June 1, 2007. Among those 114 patients 56 were men and 57 were women with the average age 65 (ranging from 28-86) years. A series of various laparoscopic operations have been performed for malignant disease mainly (almost 80%). The pre-surgical treatment, preparation of patients and the types of the operations were identical to those applied in patients treated by open surgery. Patients with colon carcinoma have been operated on with the principles of oncologic radicality. In post-operative period we encountered eight complications (four minor and four major) with only one fatal outcome. According to our experience and the facts found in literature, the results of laparoscopic colon surgery are comparable with open surgery.     

血清HE4、VEGF、MCP-1及CCL20与乳腺癌患者保乳术后局部复发的关系研究

摘要 目的：探讨血清人附睾蛋白4（HE4）、血管内皮生长因子（VEGF）、单核细胞趋化因子-1（MCP-1）及CC趋化因子配体20（CCL20）与乳腺癌患者保乳术后局部复发的关系。方法：选择2015年7月~2018年7月期间本院收治的乳腺癌患者312例作为研究对象,均符合保乳术手术指征,成功实施乳腺癌保乳术,所有患者均随访3年。检测两组血清HE4、VEGF、MCP-1、CCL20水平情况,单因素及多因素Logistic回归分析影响术后局部复发的因素。使用受试者工作特征（ROC）曲线分析HE4、VEGF、MCP-1、CCL20水平单独及联合检测对保乳术后局部复发的预测价值。结果：随访过程中失访6例,剩余的306例患者根据随访结果,分为局部复发组27例、无局部复发组279例,局部复发率为8.82%。局部复发组的血清HE4、VEGF、MCP-1、CCL20水平均高于无局部复发组（P<0.05）。单因素分析结果显示,乳腺癌患者保乳术后局部复发与年龄、淋巴结转移、切缘状态、人表皮生长因子受体2（Her-2）、细胞增殖相关抗原（Ki-67）、术后规范化疗、术后足程放疗有关（P<0.05）。多因素Logistic回归分析结果显示术后规范化疗、年龄偏高、术后足程放疗是保乳术后局部复发的保护因素,HE4、VEGF、MCP-1、CCL20水平偏高,切缘状态、Her-2、Ki-67阳性以及淋巴结转移是保乳术后局部复发的危险因素（P<0.05）。HE4、VEGF、MCP-1、CCL20联合应用预测乳腺癌患者保乳术后局部复发的效能高于单一指标应用。结论：乳腺癌保乳术后局部复发患者体内HE4、VEGF、MCP-1、CCL20水平高表达,四指标联合检测可辅助预测保乳术后局部复发。且乳腺癌患者保乳术后复发还受到切缘状态、Her-2、Ki-67等多种因素的影响。     

肺癌患者血清CEA、CYFRA21-1和NSE的检测及临床意义

目的探讨外周血癌胚抗原(CEA)、细胞角蛋白19片段(CYFRA21-1)和神经元特异性烯醇化酶(NSE)的检测对肺癌的诊断、病理分型和疗效判断的临床用价值。方法采用化学发光法检测了62例肺癌患者、54例良性肺部疾病患者、36例健康人、40例肺癌患者手术前后血清CEA、CYFRA21-1和NSE的水平。结果肺癌患者手术前血清CEA、CYFRA21-1和NSE的含量明显高于良性肺部疾病组及正常对照组(P0.01)。鳞癌组、腺癌组和小细胞癌组之间肿瘤标志物CEA、CYFRA21-1和NSE水平差异有统计学意义。CEA阳性率以腺癌组最高(84%),CYFRA21-1阳性率以鳞癌组最高(85.2%),NSE阳性率以小细胞癌组最高(80.0%)。手术治疗后未复发转移组CEA、CYFRA21-1和NSE水平低于术前,而复发转移组与术前比变化不显著(P0.05)。结论血清CEA、CYFRA21-1和NSE的检测对不同病理类型肺癌患者的诊断、病情检测及疗效判断有较好的临床参考价值。     

The role of nipple discharge cytology in the diagnosis of breast disease: a study of 1948 nipple discharge smears from 1530 patients

In this study a review of 1948 nipple discharge (ND) samples from 1530 patients in the age range of 18-83 years was undertaken to determine whether cytological findings from ND smears could provide useful diagnostic information regarding various breast lesions. The study included 1494 females and 36 males and was carried out during a period of 20 years 8 months. The clinical information in all patients was obtained from clinicians (coauthors), medical records and a review of biopsies in 205 patients who had undergone surgery following the cytodiagnosis. Of the ND samples examined, 1480 were unilateral while 468 were from 234 bilateral ND. The cytodiagnoses were: benign 624, inadequate (despite two to three repeat samples) 492, inflammatory 96, papillary lesion not otherwise specified (NOS) 229, suspicious 22 (21 females, one male) and malignant 67 (63 females, four males). A breast biopsy in the 22 suspicious cases revealed breast carcinoma in 18 cases (females n = 17, male n = 1), atypical ductal hyperplasia (female n = 1), fibroadenoma (female n = 1) and a papilloma in two females. In the 67 cases with a diagnosis of malignancy 65 revealed a breast carcinoma in the biopsy (female n = 62, male n = 3) while one female was diagnosed as fibroadenoma and one male as florid gynaecomastia. In 63 cases (females n = 61; males n = 2) with clinical lumpy areas consistent with the diagnosis of fibrocystic condition in ND, the biopsy confirmed a fibrocystic process. In 53 of 229 cases with ND findings suggestive of a papillary lesion (NOS) the biopsy revealed a papilloma in 41 cases while in 12 cases no lesion was found. In the remaining cases of all the groups only a clinical follow-up and appropriate investigations were performed with no untoward outcome. Based on our study it is felt that cytological examination of ND smears seems to be a reasonably specific method in the diagnosis of malignant and suspicious cases but may be somewhat less specific for other diagnoses.     

Possible prognostic significance of p53 and Ki 67 in inverted sinonasal papilloma

The aim of this study is to test the possible prognostic significance of p53 and Ki67 expression in inverted papilloma of the lateral nasal wall and adjacent sinuses regarding their malignant potential and recurrence. 49 biopsies of the lateral nasal wall and adjacent sinuses obtained from 41 patients from three hospitals were investigated. Immunohistochemically demonstrated p53 and Ki67 expression was measured and statistically evaluated. p53 immunoreactivity was demonstrated in most of papillomas with carcinomas but only in two benign papillomas, while Ki67 demonstrated stronger immunoreactivity in carcinomas and surrounding epithelium. Immunohistochemical staining of inverted sinonasal papillomas for p53 and Ki67 can give useful information concerning the existence of synchronous carcinoma and, in case of high Ki67, a hint toward possible recurrence.     

腹腔镜疝修补术与传统修补术治疗腹股沟疝的效果比较

目的:探讨腹腔镜手术修补腹股沟疝的临床效果,为普外科手术治疗提供可借鉴的方法。方法:选取2011年5月-2013年8月在我院接受疝修补术的112例患者的临床资料进行分析。根据手术方式,将所选病例分为传统开腹式疝修补术组(48例)和腹腔镜疝修补术组(64例)。分析并比较两组患者的术中出血量、手术时间、排气时间、肢体活动时间、复发率及并发症的发生率等。结果:腹腔镜疝修补术组患者的术中出血量、手术时间、排气、肢体活动及住院时间等临床指标均显著优于采用传统疝修补术的患者,差异显著且具有统计学意义(P0.05)。腹腔镜疝修补术组并发症发生率为21.88%,虽然低于传统疝修补术组(39.58%),但无显著性差异(P0.05)。腹腔镜疝修补术组复发率为3.13%,明显低于传统疝修补术组(8.33%),差异具有统计学意义(P0.05)。结论:腹腔镜疝修补术具有创伤小、恢复快及复发率低等优势,效果显著值得推广。但术后易发生肠粘连、阴囊血肿等并发症,术中应妥善处理,尽量减少或避免并发症的发生率。     

326 例眼睑肿物的临床病理分析

目的:总结眼睑肿物的临床病理类型及特点。方法:收集2000年1月至2011年6月到青岛大学医学院附属医院眼科住院部行手术治疗眼睑肿物患者326例的临床病理资料进行分析。结果:在326例眼睑肿物中,良性肿瘤156例,占47.9%,恶性肿瘤63例,占19.3%;炎性改变98例,占30.1%。良性肿瘤的前五位分别是色素痣、乳头状瘤、囊肿、疣、血管瘤;恶性肿瘤前三位分别是基底细胞癌、睑板腺癌、鳞状细胞癌;炎性改变以炎性肉芽肿最常见。儿童多发的眼睑肿物为皮样瘤、钙化上皮瘤。结论:眼睑病变以良性肿瘤多见,其次为炎性改变。良性肿瘤中以色素痣、乳头状瘤和囊肿多见;恶性肿瘤最常见的为基底细胞癌,儿童眼睑肿瘤以皮样瘤最多见。     

肾嗜酸性细胞瘤的诊治体会（附11例报告）

目的：探讨肾嗜酸细胞瘤的诊断和治疗。方法：回顾分析我院2003．2009年间收治11例肾嗜酸细胞瘤的临床资料,结合文献对肾嗜酸细胞瘤的诊断及治疗进行复习讨论。结果：本组11例患者中,年龄为26—75岁,男性7例,女性4例。合并透明细胞癌者1例,术前误诊为肾上腺肿瘤者1例。7例行根治性肾切除术者,4例行肾部分切除术。术后随访11个月-7年未见肿瘤转移或复发。结论：肾嗜酸细胞瘤倾向于良性肾实质性肿瘤,临床表现无特异性,确诊需临床表现、影像学检查与病理学检查相结合。治疗首选保肾手术,但应注意并发恶性肿瘤的可能,加强随访。

Primary cutaneous adenoid cystic carcinoma: a case report and review of the literature.

A case of adenoid cystic carcinoma of the ear in a 67-year-old man is presented along with a review of the literature. Adenoid cystic carcinoma most commonly arises in the salivary glands. Primary cutaneous adenoid cystic carcinoma occurs principally in the scalp and chest. Perineural invasion is seen in at least half the cases and is associated with an increased recurrence rate. Treatment consists of wide local resection with tumor-free margins. Just over half the patients will develop recurrence, with long tumor-free intervals necessitating long-term follow-up. Distant metastases are rarely seen. Radiation therapy is not curative and should be reserved for palliation.     

Long-term results of hemipelvic allograft: Report of four cases

Reconstruction after the excision of pelvic tumors involving the pelvic ring implies difficult problems. Restoration of the function is difficult and an allograft can be one of the possible solutions. Pelvic allograft is recommended by many authors to reconstruct the pelvic ring following extensive resections of bone tumors. Between 1988 and 1989, we performed hemipelvic resection and allograft reconstruction in 4 patients with pelvic sarcomas. The mean age was 42.3 years (range 38–48), consists of 3 male and 1 female. One case developed an infection and one case showed recurrence, both responding to surgical treatment. Outcome in those cases in which surgery was curative to the primary tumor was satisfactory at 10 years follow-up, with a mean total Enneking score of 25.3 (range 24–27) and a good functional result in Merlé D'Aubigne functional score. Despite the limited number of cases presented, our results added to the reported results in the literature led us to consider that allografts are valuable in pelvic reconstructions after en-bloc resections for bone tumors. This revised version was published online in July 2006 with corrections to the Cover Date.     

Prediction of recurrence in giant cell bone tumors by DNA cytometry.

The most interesting therapeutic aspect of giant cell bone tumors is which patients can be cured without a risk of recurrence by intralesional surgery (curettage). To find out the suitability of some DNA cytometric and morphometric parameters for showing differences between this group of patients (n = 9) and those with recurrence (n = 12), the parameters mean ploidy, 2cDI (mean square deviation of the tumor cell DNA content from the normal 2c value), mean nuclear area and its variability were calculated from cytologic specimens prepared by a cell separation technique from formalin-fixed, paraffin-embedded tissues, measuring the values of 100 stromal cells per case by a TV image analysis system. Further measurements were performed on 19 cases of different diseases of the bone and on an additional 17 cases of giant cell tumors without follow-up. The 2cDI allowed us to distinguish the two groups of patients, with and without recurrence, without overlap; even the lowest value for patients with recurrence was higher than the highest value for cured ones. Mean ploidy analysis resulted in a less convincing discrimination of the patients. Mean nuclear area and its variability failed to predict recurrence. Single-cell DNA cytometry provided a parameter, 2cDI, that was able to predict recurrence in patients with giant cell bone tumors with high sensitivity.     

Value of outpatient follow-up after curative surgery for carcinoma of the large bowel.

The records were reviewed of 406 patients with carcinoma of the large bowel who had been treated at the Middlesex Hospital during 1958-62. Of these patients, 180 were followed up regularly in this hospital after radical surgery, and from six months to 15 years after operation they were seen 2319 times; 71 developed a recurrent carcinoma but, of these, 41 recurrences (58%) were diagnosed at times other than those of the patients'' routine outpatient appointments, although they were being regularly reviewed. Only one patient with recurrence appeared to have been cured by further surgery. For the present, adequate education of patients in the symptoms of early recurrence, with instruction to return if any of these develop, is likely to be more effective than the unsatisfactory and time-consuming routine follow-up still used in many hospitals.     

Association hyperthyroïdie et cancer thyroïdien différencié (médullaire exclu). À propos de sept observations

The aim of this study was to draw attention to the fact that hyperthyroidism does not exclude the possibility of concurrent thyroid carcinoma. We analyzed the frequency and consequences of this association through seven cases of thyrotoxic patients with differentiated thyroid carcinoma followed by a review of literature.

Patients and methods

The nuclear medicine department of the CHU Ibn Sina has more than 3000 cases of differentiated thyroid carcinoma where 10 patients with association of hyperthyroidism could be retrieved. Our study focused on seven cases well documented and regularly followed. The main parameters collected were the following: age, sex, personal and family history of thyroid disease, clinical presentation, etiology of hyperthyroidism, preoperative paraclinical explorations, surgery performed, histopahological findings, complementary therapy and follow-up.

Results

Group included six females and one male, average age was 41.4 years. There were four cases of Graves’ disease, two cases of single toxic nodule and one case of functional multinodular goiter. All patients underwent total thyroidectomy. Final pathologic examination disclosed five papillary carcinomas and two follicular carcinomas. During 2 to 8 years follow-up, there was neither local recurrence nor metastasis.

Conclusion

The diagnosis of hyperthyroidism does not preclude concurrent thyroid carcinoma. Careful assessment of such patients is mandatory to exclude an associated thyroid malignancy particularly in the presence of a nodule in a hyperfunctioning thyroid.     

Solitary Renal Fossa Recurrence of Renal Cell Carcinoma After Nephrectomy

Renal cell carcinoma without metastasis responds well to surgical excision but is known to recur postnephrectomy. In a small but significant number of patients this recurrence is not accompanied by metastasis, which is important as these people benefit from further surgery. We examined 20 articles from the current literature to ascertain how best to treat this condition. Surgical management renders better results than conservative or medical therapies. Readily available investigations such as blood tests and computed tomography can help determine the right patients for surgery in an evidence-based fashion. Current findings have allowed us to suggest a protocol for the treatment of solitary renal fossa recurrence of postnephrectomy renal cell carcinoma. There are further opportunities for study in validating our protocol, and in novel renal cell carcinoma treatment strategies that have not been tested on solitary renal fossa recurrences.Key words: Renal cancer, Recurrence, Nephrectomy, Complications, ManagementKidney cancers represent 2% of cancers worldwide; the most common type is renal cell carcinoma. Curative treatment of localized disease is a nephrectomy. Following surgery, recurrence can happen locally with an incidence of 1.61%.^1–5 A solitary renal fossa local recurrence is rare but important to distinguish from local recurrence with metastasis, which would not benefit from surgical resection. The 5-year survival postresection of local recurrence for those without metastasis compared with those with metastasis was 62% compared with 0%.⁴ The kidneys are bordered by the colon, spleen, liver, stomach, and associated neurovascular structures, all of which may be invaded in this form of recurrence; specific morbidity is related to the invasion and subsequent resection of these organs. General morbidity is caused by the surgery itself, with pain, infection, and hemorrhage being major contributors (Figure 1). This article explains predictive factors in recurrence, useful diagnostic modalities, and management, and provides recommendations and highlights opportunities for further study.Open in a separate windowFigure 1Computed tomography image of a patient with renal fossa recurrence of renal cancer after nephrectomy.

分子生物学法分析青少年甲状腺肿物临床病理及特点

探讨青少年甲状腺肿物的临床病理学特点,甲状腺癌的复发、转移和结节性甲状腺肿复发的可能相关因素。按WHO病理分型标准和国际抗癌联盟(UICC)TNM分期标准回顾性分析青少年甲状腺肿物124例及其中部分甲状腺癌和结节性甲状腺肿的随访资料。124例甲状腺肿物患者男女比例约为1 3,甲状腺癌39例(31.5%),其中乳头状癌35例,滤泡癌3例,髓样癌1例;甲状腺腺瘤59例(47.6%),结节性甲状腺肿11例(8.9%),结节性甲状腺肿伴腺瘤7例(5.6%),甲状腺炎5例(4%),甲状舌管囊肿3例(2.4%)。本组资料显示,青少年甲状腺癌以乳头状癌为主,其复发、转移与组织学亚型为弥漫硬化型及甲状腺包膜和其外软组织受侵状态相关。虽然常见淋巴结转移、肺转移以及局部侵犯周围软组织,但患者总体预后较好。结节性甲状腺肿的复发与病变弥漫位于双叶有关,而与患者性别、年龄和是否伴有乳头样及腺瘤样增生关系不密切。     

Treatment of Basal Cell Carcinoma of the Eyelids by Radiotherapy

One hundred and nineteen cases of basal cell carcinoma of the eyelid were reviewed to determine the efficacy of radiotherapy for treatment of this lesion. In 61 of 111 patients, the tumour was at the medial canthus or inner third of the lower lid. The greatest incidence was in the 60 to 69 age group. Most of the patients were treated with 85-120 kV radiation and given a dosage of 3000-5000 roentgens. Fifty per cent were followed up for at least four years. There were few complications. There were eight recurrences. Four of these were from a subgroup of 21 patients that had had previous surgery. It is concluded that radiotherapy is a good method of treating basal cell carcinoma of the lid, although previous surgery would appear to increase the likelihood of subsequent recurrence.
