Objectives: The authors reported a retrospective study on myxoid liposarcomas (MLs), evaluating factors that may influence overall survival (OS), local recurrence-free survival (LRFS), metastasis-free survival (MFS), and analyzing the metastatic pattern.

Methods: 148 MLs were analyzed. The sites of metastases were investigated.

Results: Margins (p = 0.002), grading (p = 0,0479), and metastasis (p < 0,0001) were significant risk factors affecting overall survival (OS). Type of presentation (p = 0.0243), grading (p = 0,0055), margin (p = 0.0001), and local recurrence (0.0437) were risk factors on metastasis-free survival (MFS). Authors did not observe statistically significant risk factors for local recurrence-free survival (LRFS) and reported 55% extrapulmonary metastases and 45% pulmonary metastases.

Conclusion: Margins, grading, presentation, local recurrence, and metastasis were prognostic factors. Extrapulmonary metastases were more frequent in myxoid liposarcoma.

研究目的作者报告了一项关于肌样脂肪肉瘤(MLs)的回顾性研究,评估了可能影响总生存期(OS)、无局部复发生存期(LRFS)、无转移生存期(MFS)的因素,并分析了转移模式。方法:对 148 例 ML 进行分析,调查转移部位:边缘(p = 0.002)、分级(p = 0.0479)和转移(p < 0.0001)是影响总生存期(OS)的重要风险因素。发病类型(p = 0.0243)、分级(p = 0.0055)、边缘(p = 0.0001)和局部复发(0.0437)是影响无转移生存期(MFS)的风险因素。作者没有观察到对无局部复发生存期(LRFS)有统计学意义的风险因素,并报告了55%的肺外转移和45%的肺转移:结论:边缘、分级、表现、局部复发和转移是预后因素。肺外转移在肌样脂肪肉瘤中更为常见。

Background: Adult granulosa cell tumors (AGCTs) are the most common sex cord-stromal tumors. Unlike epithelial ovarian tumors, they occur in young women and are usually detected at an early stage. The aim of this study was to report the clinical and pathological characteristics of AGCT patients and to identify the prognostic factors.

Methods: All cases of AGCTs, treated at Salah Azaïz Institute between 1995 and 2010, were retrospectively included. Kaplan-Meier's statistical method was used to assess the relapse-free survival and the overall survival.

Results: The final cohort included 31 patients with AGCT. The mean age was 53 years (35-73 years). Patients mainly presented with abdominal mass and/or pain (61%, n = 19). Mean tumor size was 20 cm. The majority of patients had a stage I disease (61%,  n = 19). Two among 3 patients with stage IV disease had liver metastasis. Mitotic index was low in 45% of cases (n = 14). Surgical treatment was optimal in almost all cases (90%, n = 28). The median follow-up time was 14 years (1-184 months). Ten patients relapsed (32%) with a median RFS of 8.4 years (6.8-9.9 years). Mean overall survival was 13 years (11-15 years). Stage I disease and low-to-intermediate mitotic index were associated with a better prognosis in univariate analysis (resp., p = 0.05 and p = 0.02) but were not independent prognostic factors.

Conclusion: GCTs have a long natural history with common late relapses. Hence, long active follow-up is recommended. In Tunisian patients, hepatic metastases were more frequent than occidental series. The prognosis remains good and initial staging at diagnosis is an important prognostic factor.

背景:成人颗粒细胞瘤(agct)是最常见的性索间质肿瘤。与卵巢上皮性肿瘤不同,它们发生在年轻女性中,通常在早期被发现。本研究的目的是报告AGCT患者的临床和病理特征,并确定预后因素。方法:回顾性分析Salah Azaïz研究所1995年至2010年间治疗的所有agct病例。采用Kaplan-Meier统计方法评估无复发生存期和总生存期。结果:最终队列包括31例AGCT患者。平均年龄53岁(35 ~ 73岁)。患者主要表现为腹部肿块和/或疼痛(61%,n = 19)。肿瘤平均大小为20cm。大多数患者为I期疾病(61%,n = 19)。3例IV期患者中2例出现肝转移。有丝分裂指数低的病例占45% (n = 14)。手术治疗在几乎所有病例(90%,n = 28)中都是最佳的。中位随访时间为14年(1 ~ 184个月)。10例患者复发(32%),中位RFS为8.4年(6.8-9.9年)。平均总生存期为13年(11-15年)。单变量分析显示,I期疾病和低至中等有丝分裂指数与较好的预后相关。, p = 0.05和p = 0.02),但不是独立的预后因素。结论:gct具有较长的自然病程,常见的晚期复发。因此,建议长期积极随访。在突尼斯患者中,肝转移比西方患者更常见。预后良好,诊断时的初始分期是一个重要的预后因素。

Background and objectives: Most gastric cancer patients now undergo perioperative chemotherapy (POCT) based on the MAGIC trial results. POCT consists of neoadjuvant chemotherapy (NACT) as well as postoperative adjuvant chemotherapy. This study assessed the applicability of perioperative chemotherapy and the impact of radical gastrectomy encompassing a detailed lymph-node resection on outcomes of gastric cancer.

Methods: Medical and pathology records of all gastric carcinoma resections were reviewed from 2006 onwards. Pathological details, number of lymph-nodes resected, and proportion of involved nodes, reasons for nonadministration of NACT, complications, recurrence, and survival data were analysed.

Results: Only twenty-eight (37.8%) out of 74 patients underwent NACT and only nine completed POCT. NACT was declined due to comorbidities/patient refusal n = 24, early stage n = 14, and emergency presentation n = 8. Patients receiving NACT were much younger. Anastomotic leaks, hospital-mortality, lymph-node yield, and proportion of involved lymph-nodes were similar in both groups. Thirty-two patients died due to recurrence with lymph-node involvement heralding higher recurrence risk and much poorer survival (HR 2.66; p = 0.013).

Conclusion: More than 60% patients with resectable gastric carcinoma did not undergo NACT. Radical gastrectomy with lymphadenectomy remained the cornerstone of treatment in this period.

背景和目的:基于MAGIC试验结果,大多数胃癌患者现在接受围手术期化疗(POCT)。POCT包括新辅助化疗(NACT)和术后辅助化疗。本研究评估围手术期化疗的适用性和胃癌根治性切除术包括详细淋巴结切除术对胃癌预后的影响。方法:回顾2006年以来所有胃癌切除术的医学和病理记录。分析病理细节、切除淋巴结数量、受累性淋巴结比例、未给予NACT的原因、并发症、复发和生存数据。结果:74例患者中只有28例(37.8%)接受了NACT,只有9例完成了POCT。NACT因合并症/患者拒绝24例,早期14例,急诊8例而被拒绝。接受NACT治疗的患者更年轻。吻合口漏、住院死亡率、淋巴结产量和受累淋巴结比例在两组中相似。32例患者因复发并累及淋巴结而死亡,预示着更高的复发风险和更差的生存率(HR 2.66;P = 0.013)。结论:60%以上的可切除胃癌患者未行NACT手术。根治性胃切除术加淋巴结切除术仍然是这一时期治疗的基石。

Background: A meta-analysis was conducted in order to provide an up-to-date comparison of pancreatogastrostomy (PG) and pancreatojejunostomy (PJ), after pancreatoduodenectomy (PD), in terms of clinically significant postoperative pancreatic fistula (POPF) and other postoperative complications.

Methods: This meta-analysis was conducted according to the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. A systematic literature search in MEDLINE and Cochrane Central Register of Controlled Clinical Trials was performed. Fixed Effects or Random Effects model was used, based on the Cochran Q test.

Results: In total, 10 studies (1629 patients) were included. There was no statistical significance between PG and PJ regarding the rate of clinically significant POPF (OR: 0.70, 95%CI: 0.46-1.06). PG was associated with a higher rate of postpancreatoduodenectomy haemorrhage (PPH) (OR: 1.52, 95%CI: 1.08-2.14). There was no difference between the two techniques in terms of clinically significant PPH (OR: 1.35, 95%CI: 0.95-1.93) and clinically significant postoperative delayed gastric emptying (DGE) (OR: 0.98, 95%CI: 0.59-1.63).

Discussion: There is no difference between the two anastomotic techniques regarding the rate of clinically significant POPF. Given several limitations, more large scale high quality RCTs are required.

背景:一项荟萃分析旨在比较胰十二指肠切除术(PD)后胰胃吻合术(PG)和胰空肠吻合术(PJ)在临床上显著的术后胰瘘(POPF)和其他术后并发症方面的最新情况。方法:本荟萃分析依据PRISMA指南和Cochrane干预措施系统评价手册进行。在MEDLINE和Cochrane对照临床试验中央注册库中进行了系统的文献检索。采用固定效应或随机效应模型,基于Cochran Q检验。结果:共纳入10项研究(1629例患者)。PG组与PJ组临床显著性POPF发生率比较,差异无统计学意义(OR: 0.70, 95%CI: 0.46 ~ 1.06)。PG与胰十二指肠切除术后出血(PPH)发生率较高相关(OR: 1.52, 95%CI: 1.08-2.14)。两种方法在临床显著的PPH (OR: 1.35, 95%CI: 0.95-1.93)和临床显著的术后胃排空延迟(DGE) (OR: 0.98, 95%CI: 0.59-1.63)方面无差异。讨论:两种吻合技术在临床上显著的POPF发生率方面没有差异。考虑到一些限制,需要更多的大规模高质量随机对照试验。

Objective. Retrospective studies have found that noninvasive encapsulated follicular variant of papillary thyroid cancer (EFVPTC) exhibits highly indolent clinical behavior. We studied the clinical features of our patients with noninvasive EFVPTC tumors culled from a community endocrine surgical practice registry over the past four years. Methods. We interrogated the Memorial Center for Integrative Endocrine Surgery (MCIES) Registry for all recorded encapsulated follicular variant of papillary cancer pathologic diagnoses. We identified a subgroup of patients without capsular or vascular invasion and studied their clinical characteristics. Results. Thirty-seven patients met inclusion and exclusion criteria. The typical patient was young and female. Nodules averaged 3.1 cm in greatest dimension by ultrasound evaluation. Thirteen patients were found to have synchronous malignancies elsewhere in the thyroid (35%). At the time of this writing, we have not seen a clinical recurrence in any of our 37 noninvasive EFVPTC patients. Conclusions. Early clinical follow-up data suggests that the majority of noninvasive EFVPTC tumors exhibit indolent behavior, but clinical decision-making with regard to completion thyroidectomy, central lymph node dissection, and adjunctive radioiodine therapy often depends on the amount and type of synchronous thyroid cancer detected elsewhere in the thyroid gland and the central neck.

目标。回顾性研究发现,非侵袭性囊泡型甲状腺乳头状癌(EFVPTC)表现出高度惰性的临床行为。我们研究了过去四年来从社区内分泌外科实践登记处挑选的非侵入性EFVPTC肿瘤患者的临床特征。方法。我们询问了综合内分泌外科纪念中心(MCIES)登记处记录的所有包膜滤泡变异型乳头状癌病理诊断。我们确定了一组没有被囊或血管侵犯的患者,并研究了他们的临床特征。结果。37例患者符合纳入和排除标准。典型的患者为年轻女性。超声检查结节平均最大尺寸为3.1 cm。13例患者在甲状腺其他部位发现同步恶性肿瘤(35%)。在撰写本文时,我们尚未发现37例无创EFVPTC患者的临床复发。结论。早期临床随访资料显示,大多数非侵袭性EFVPTC肿瘤表现为惰性行为,但临床决定是否完成甲状腺切除术、中央淋巴结清扫和辅助放射性碘治疗,往往取决于甲状腺和中央颈部其他部位检测到的同步甲状腺癌的数量和类型。

Locally advanced right colon cancer may invade adjacent tissue and organs. Direct invasion of the duodenum and pancreas necessitates an en bloc resection. Previously, this challenging procedure was associated with high morbidity and mortality; however, today, this procedure can be done more safely in experienced centers. The aim of this study is to report our experience on en bloc right colectomy with pancreaticoduodenectomy for locally advanced right colon cancers. Between 2000 and 2012, 5 patients underwent en bloc multivisceral resection. No major morbidities or perioperative mortalities were observed. Median disease-free survival time was 24.5 months and median overall survival time was 42.1 (range: 4.5-70.4) months in our series. One patient lived 70 months after multivisceral resection and underwent cytoreductive surgery and total pelvic exenteration during the follow-up period. In locally advanced right colon tumors, all adhesions should be considered as malign invasion and separation should not be done.

局部晚期右结肠癌可侵犯邻近组织和器官。直接侵犯十二指肠和胰腺需要进行整体切除。以前,这种具有挑战性的手术与高发病率和死亡率有关;然而,今天,这个过程可以在有经验的中心更安全地完成。本研究的目的是报告我们对局部晚期右结肠癌进行整体右结肠切除联合胰十二指肠切除术的经验。2000年至2012年间,5例患者接受了整体多脏器切除术。未观察到主要发病率或围手术期死亡率。在我们的研究中,中位无病生存时间为24.5个月,中位总生存时间为42.1个月(范围:4.5-70.4)。1例患者在多脏器切除后存活了70个月,并在随访期间接受了细胞减少手术和全盆腔切除术。局部进展的右结肠肿瘤,所有粘连应考虑为恶性侵犯,不应进行分离。该患者的合理选择是进行整体胰十二指肠切除术和右结肠切除术。该手术可导致长期生存,发病率和死亡率可接受。多学科的团队合作和多模式的治疗方案可以改善结果。

In the UK, more than 3,200 new cases of cervical cancer are diagnosed each year. Early stage cervical cancer (IA2-IB1) treatment comprises central surgery mainly in the form of radical hysterectomy or fertility sparing surgery including trachelectomy as well as systematic pelvic lymphadenectomy to detect metastases and adjust treatment accordingly. Given the variation in determining the lymph node (LN) status, a major prognosticator, we reviewed the current UK practice of LN assessment in women undergoing surgery for early cervical cancer. A 7-question, web-based survey, screened by the BGCS committee, was circulated amongst BGCS members. The overall response rate was 51%. Only 12.5% of the respondents routinely performed frozen section examination (FSE); the main reasons for not doing FSE were the pressure on theatre time (54.5%) and the lack of available facilities (48.5%). When positive pelvic nodal disease was detected, in 21 out of 50 (42%) the planned radical hysterectomy (RH) was aborted. More than 70% of the respondents routinely performed RH without any prior resort to pelvic lymphadenectomy. Pretreatment surgical para-aortic LN assessment was performed by 20% of the respondents. The survey confirms the diversity of the UK practice patterns in the surgical treatment of early cervical cancer.

在英国,每年有超过3,200例新的宫颈癌病例被诊断出来。早期宫颈癌(IA2-IB1)的治疗包括中心手术,主要是根治性子宫切除术或保留生育能力的手术,包括气管切除术,以及系统的盆腔淋巴结切除术,以发现转移并相应地调整治疗。鉴于确定淋巴结(LN)状态的差异,这是一个主要的预后指标,我们回顾了目前英国对接受早期宫颈癌手术的妇女进行LN评估的做法。由BGCS委员会筛选的一份有7个问题的网络调查在BGCS成员中分发。总有效率为51%。只有12.5%的受访者常规进行冷冻切片检查(FSE);不做FSE的主要原因是剧院时间紧张(54.5%)和缺乏可用设施(48.5%)。当检测到盆腔淋巴结疾病阳性时,50例中有21例(42%)计划根治性子宫切除术(RH)流产。超过70%的应答者常规行RH,之前未行盆腔淋巴结切除术。20%的应答者进行了手术前主动脉旁LN评估。调查证实了英国早期子宫颈癌手术治疗模式的多样性。

Introduction: Emergency resection represents the traditional treatment for left-sided malignant obstruction. However, the placement of self-expanding metallic stents and delayed surgery has been proposed as an alternative approach. The aim of the current meta-analysis was to review the available evidence, with particular interest for the short-term outcomes, including a recent multicentre RCT.

Methods: We considered randomized controlled trials comparing stenting as a bridge to surgery and emergency surgery for the management of left-sided malignant large bowel obstruction, performing a systematic review in MEDLINE, PubMed database, and the Cochrane libraries.

Results: We initially identified a total of 2543 studies. After the elimination of duplicates and the screening of titles and abstracts, seven studies, for a total of 448 patients, were considered. The current meta-analysis revealed no difference in the mortality rate between the stent group and the emergency surgery group; the postoperative complication rate (37.84% versus 54.87%, P = 0.02), the stoma rate (28.8% versus 46.02%, P < 0.0001), and the incidence of wound infection (8.11% versus 15.49%, P = 0.01) were reduced after stent as a bridge to surgery.

Conclusion: Colonic stenting as a bridge to surgery appears to be a safe approach to malignant large bowel obstruction. Possible advantages of this treatment can be identified in a reduced incidence of postoperative complications and a lower stoma rate. Further RCTs considering long-term outcomes and cost-effectiveness analysis are needed.

简介:急诊切除术是治疗左侧恶性梗阻的传统方法:急诊切除术是治疗左侧恶性梗阻的传统方法。不过,也有人提出了放置自膨胀金属支架和延迟手术的替代方法。本荟萃分析旨在回顾现有证据,尤其关注短期疗效,包括最近的一项多中心 RCT:方法:我们在 MEDLINE、PubMed 数据库和 Cochrane 图书馆中进行了系统性综述,考虑了在处理左侧恶性大肠梗阻时将支架植入术作为手术桥梁与急诊手术进行比较的随机对照试验:我们初步确定了 2543 项研究。结果:我们最初共发现了 2543 项研究,在剔除重复研究并筛选了标题和摘要后,我们考虑了 7 项研究,共计 448 名患者。目前的荟萃分析显示,支架组和急诊手术组的死亡率没有差异;支架作为手术的桥梁后,术后并发症发生率(37.84% 对 54.87%,P = 0.02)、造口率(28.8% 对 46.02%,P < 0.0001)和伤口感染发生率(8.11% 对 15.49%,P = 0.01)均有所降低:结肠支架作为手术的桥梁似乎是治疗恶性大肠梗阻的一种安全方法。结肠支架作为手术桥梁似乎是一种安全的恶性大肠梗阻治疗方法,这种治疗方法的优势可能体现在术后并发症发生率降低和造口率降低。还需要进行更多的研究性试验,考虑长期疗效和成本效益分析。

Our understanding of the biology, genetics, and natural history of neuroendocrine tumors (NETs) of the gastrointestinal tract and pancreas has improved considerably in the last several decades and the spectrum of available therapeutic options is rapidly expanding. The management of patients with metastatic low or intermediate grade NETs has been revolutionized by the development of new treatment strategies such as molecular targeting therapies with everolimus and sunitinib, somatostatin analogs, tryptophan hydroxylase inhibitors, and peptide receptor radionuclide therapy that can be used alone or as a multimodal approach with or without surgery. To further define and clarify the utility, appropriateness, and the sequence of the growing list of available therapies for this patient population will require more high level evidence; however, data from well-designed randomized phase III clinical trials is rapidly accumulating that will further stimulate development of new management strategies. It is therefore important to thoroughly review emerging evidence and report major findings in frequent updates, which will expand our knowledge and contribute to a better understanding, characterization, and management of advanced NETs.

在过去的几十年里,我们对胃肠道和胰腺神经内分泌肿瘤(NETs)的生物学、遗传学和自然史的了解有了很大的提高,可用的治疗选择范围也在迅速扩大。转移性低或中级NETs患者的管理已经通过新的治疗策略的发展发生了革命性的变化,如依维莫司和舒尼替尼的分子靶向治疗、生长抑素类似物、色氨酸羟化酶抑制剂和肽受体放射性核素治疗,这些治疗方法可以单独使用,也可以作为多模式方法,有或没有手术。为了进一步定义和澄清这一患者群体的效用、适当性和可用治疗的顺序,将需要更多的高水平证据;然而,精心设计的随机III期临床试验的数据正在迅速积累,这将进一步刺激新的管理策略的发展。因此,重要的是彻底审查新出现的证据,并在频繁更新中报告主要发现,这将扩大我们的知识,并有助于更好地理解、表征和管理先进的网络。

Reconstructive surgery following skin tumor resection can be challenging. Treatment options after removing the tumor are skin grafting, local pedicled and axial flaps, or microsurgery for complex and extensive wounds correction. Recently, the use of dermal substitutes has been extended to reconstructive surgery in cutaneous oncology. Objectives. To report both a single-center experience using dermal substitutes in reconstructive surgery for skin malignancies and reconstructive surgery's outcomes. Methods and Results. Among thirteen patients, seven (53.8%) were male with mean age of 62.6 years. Regarding diagnosis, there were five cases (38.5%) of basal cell carcinoma (BCC), two (15.4%) of melanoma in situ, two (15.4%) of dermatofibrosarcoma protuberans, one (7.7%) of squamous cell carcinoma (SCC), one (7.7%) of angiosarcoma, and one (7.7%) of eccrine carcinoma (EC). The most common site of injury was scalp (53.8%) and lower limbs (23.1%). Seven (53.8%) patients used NPWT and six (46.2%) patients underwent Brown's dressing. The most frequent complication of the first stage was wound contamination (38.5%). Average time to second-stage skin grafting was 43.9 days. Three (23%) patients developed tumor recurrence and one died. Conclusions. Use of dermal substitutes in oncology can be an option for reconstruction after extended resections, providing good aesthetical and functional results.

皮肤肿瘤切除后的重建手术具有挑战性。切除肿瘤后的治疗选择是植皮,局部带蒂和轴向皮瓣,或显微手术进行复杂和广泛的伤口矫正。最近,真皮替代品的使用已经扩展到皮肤肿瘤的重建手术。目标。报告在皮肤恶性肿瘤重建手术中使用真皮替代品的单中心经验和重建手术的结果。方法与结果。13例患者中男性7例(53.8%),平均年龄62.6岁。在诊断方面,基底细胞癌(BCC) 5例(38.5%),原位黑色素瘤2例(15.4%),隆突性皮肤纤维肉瘤2例(15.4%),鳞状细胞癌(SCC) 1例(7.7%),血管肉瘤1例(7.7%),内分泌癌(EC) 1例(7.7%)。最常见的损伤部位为头皮(53.8%)和下肢(23.1%)。7例(53.8%)采用NPWT, 6例(46.2%)采用布朗敷料。第一阶段最常见的并发症是伤口污染(38.5%)。二期植皮的平均时间为43.9天。3例(23%)患者肿瘤复发,1例死亡。结论。在肿瘤学中,真皮替代品的使用可以作为延长切除后重建的一种选择,提供良好的美学和功能结果。
