胸段食管鳞癌淋巴结转移规律探究

目的探讨胸段食管鳞癌淋巴结转移规律及其影响因素,以指导淋巴结清扫方式。方法回顾分析漳州市医院2010年4月至2012年7月手术治疗的328例胸段食管鳞癌的临床病理资料,探讨淋巴结转移规律及其影响因素。结果全组328例共清扫淋巴结9 937枚,平均30.3枚/例。共437枚、153例有淋巴结转移,转移率46.65%;其中喉返神经旁淋巴结转移18.30%,10.46%喉返神经旁淋巴结为唯一转移部位。胸段食管癌淋巴结转移与肿瘤部位、长度、分化程度及浸润深度明显相关。胸上段食管癌淋巴结转移方向主要向上纵隔及下颈部;胸中段食管癌颈、胸、腹均可发生淋巴结转移;胸下段食管癌主要向腹腔、中下纵隔转移。结论食管上段鳞癌,颈部淋巴结转移率高,应行三野淋巴结清扫;下段食管癌清扫重点在腹腔、中下纵隔;中段鳞癌应提倡进行个体化清扫和适度清扫;分化程度差,浸润程度深的病例应适当扩大清扫范围。胸段食管癌喉返神经旁淋巴结转移率高,均应行喉返神经旁淋巴结清扫。     

胸段食管鳞癌喉返神经旁淋巴结转移特点及临床意义

目的 :了解胸段食管鳞癌双侧喉返神经旁淋巴结的转移特点及对预后的影响,探讨合理的淋巴结清扫范围。 方法 :对120例临床资料完整胸段食管鳞癌患者的双侧喉返神经旁淋巴结转移及预后情况进行回顾性分析。 结果 :120例患者喉返神经旁旁淋巴结转移率为34.2%(41/120),其中左侧20.8%,右侧15.8%。影响喉返神经旁淋巴结转移的因素有肿瘤部位、浸润深度和组织分化程度,而与年龄、性别、肿瘤长度无关。喉返神经旁淋巴结转移的食管癌患者颈部淋巴结转移率为51.2%(21/41),明显高于无喉返神经转移组13.9%(11/79)(P<0.01)。喉返神经旁淋巴结转移患者术后局部复发为8.3%,同期非三野清扫食管癌手术组3年局部复发率为18%。喉返神经旁淋巴结转移食管癌患者3年生存期为29.3%,明显低于无淋巴结转移患者58.2%(P<0.05)。 结论 :所有胸段食管鳞癌均应行双侧喉返神经旁淋巴结清扫,有助于提高根治的彻底性、降低复发率、提高生存率。检测喉返神经淋巴结有助于指导食管癌患者是否行颈淋巴清扫术。     

胸中段食管鳞癌淋巴结转移度及合理清扫范围的临床研究

目的:本研究通过分析胸中段食管鳞癌淋巴结转移规律及淋巴结转移度对预后的影响,探讨合理的淋巴结清扫范围.方法:对129例经现代二野淋巴结清扫术的胸中段食管鳞癌患者的临床资料进行回顾性分析.结果:全组患者淋巴结转移率为56.6%,总淋巴结转移度(阳性淋巴结数/清扫淋巴结总数,LMR)为11.3%,上纵隔淋巴结转移率为43.4%.最常见的淋巴结受累区域为食管旁、右喉返神经旁、贲门及胃左血管旁、隆突下.影响淋巴结转移的主要因素为肿瘤浸润深度、分化程度及肿瘤长度.无淋巴结转移组、淋巴结转移度≤20%组和淋巴结转移度>20%组患者5年生存率分别为50.4%、31.0%和6.8%,结果差异有统计学意义(P=0.000).结论:淋巴结转移度是判断食管癌预后的一个重要因素,胸中段食管癌应该常规行包括双侧上纵隔的现代二野淋巴结清扫术.     

胸中段食管癌胸腹二野淋巴结清扫及其转移规律的临床研究

目的:探讨胸中段食管癌胸腹二野淋巴结转移规律及其清扫方法,指导临床淋巴结清扫的范围。方法:对95例胸中段食管癌采用右胸及上腹正中两切口术式为基础进行胸腹二野淋巴结清扫,并对淋巴结转移规律进行分析。结果:95例胸中段食管患者淋巴结转移度为20.4% ,肿瘤浸润深度和分化程度对淋巴结转移率的影响具有统计学意义。胸中段食管癌既有向上到右颈气管旁、双侧喉返神经链旁、食管旁、癌肿旁、隆突下淋巴结转移,也有向下至贲门旁、胃左动脉旁、胃小弯网膜等处淋巴结转移,呈现双向转移趋势。结论:胸中段食管癌患者淋巴结转移与肿瘤浸润深度及分化程度明显相关。具有胸腹二野淋巴结转移的倾向,右颈气管旁及双侧喉返神经链是淋巴结转移重要区域,右胸及上腹两切口术式更方便胸中段食管癌切除和胸腹二野淋巴结的清扫,并且以此为基础经右胸顶对右颈气管旁及双侧喉返神经链淋巴结清扫也是安全可行的。

Sentinel lymph node melanoma metastases: Assessment of tumor burden for clinical prediction of outcome in the first Multicenter Selective Lymphadenectomy Trial (MSLT-I)

PurposeAs clinical management decisions in patients with Stage III melanoma have become more complex, precise pathologic characterization of sentinel lymph node (SLN) metastases has become critical to guide management. The extent of SLN involvement correlates with risk of adverse outcomes, but reported methods of disease quantification vary. We examined SLN metastases from patients participating in an international clinical trial and compared several methods of tumor burden quantification.MethodsSLNs from 146 node-positive patients in the first Multicenter Selective Lymphadenectomy Trial (MSLT-I) were centrally-reviewed and characterized by number of tumor-positive nodes, percent nodal area tumor replacement, maximum dimension of largest metastasis, tumor penetrative depth, number of tumor foci, metastasis microanatomic location, and extracapsular extension. These data were analyzed for correlation with non-SLN metastasis and melanoma-specific survival (MSS).ResultsThe median number of tumor-involved SLNs was 1. The median maximum metastasis dimension was 1.11 mm. Median SLN area involvement was 1.5%. Tumor burden measures were highly correlated with each other. Factors associated with non-SLN metastasis by univariable analysis were primary tumor ulceration and extent of metastases. Tumor thickness, ulceration, non-SLN metastasis and multiple measures of SLN tumor burden were significantly related to MSS on univariable analysis. After multivariable adjustment, number of involved SLNs (p = 0.05) and percent nodal area tumor replacement (p = 0.02) were independent predictors of MSS.ConclusionCentral review of MSLT-I pathology indicates that primary tumor and SLN tumor characteristics predict non-SLN metastasis and MSS. Percent nodal involvement was more powerfully prognostic than the more commonly used maximum dimension of largest metastasis.

Initial metastatic, including micrometastatic, sites of lymph nodes in esophageal squamous cell carcinoma

BACKGROUND AND OBJECTIVES: It is important to identify the initial lymph node metastasis when performing less invasive surgery. The purpose of the present study was to analyze locations of solitary lymph node metastasis and micrometastasis in esophageal carcinoma. METHODS: We retrospectively analyzed the initial sites of lymph node metastasis in esophageal cancer. Sixty-five consecutive patients with solitary lymph node metastasis, and 33 pN0 patients with only lymph node micrometastasis detected by immunohistochemistry, were classified according to tumor location and tumor depth. RESULTS: The location of lymph node metastasis in the 22 patients with superficial cancer was limited to recurrent nerve nodes (RN) in the upper thoracic esophagus; RN, paraesophageal nodes (PE), or perigastric nodes (PG) in the middle or lower thoracic esophagus. Thirty-six patients with advanced cancer had lymph node metastasis at RN, PE, or PG locations, while in the remaining seven, lymph node metastasis was found in areas far from the primary tumor. Regarding the 33 patients with lymph node micrometastasis, the locations of micrometastasis were similar to those of solitary metastasis. CONCLUSIONS: Although less invasive surgery, such as reduction of lymphadenectomy, may be suitable for superficial cancer, it should be performed with special care in advanced cancer.     

Efficacy and Significance of Sentinel Lymph Node Identification with Technetium-99m-labeled Tin Colloids for Breast Cancer

Purpose  The sentinel lymph node (SLN) is thought to reflect the metastatic status of the remaining axillary lymph nodes in patients with breast cancer. We used technetium-99m-labeled tin colloids to identify SLN. The efficacy and significance of SLN identification using this method were investigated in terms of number, size, location, and tumor metastasis. The efficacy of the emulsion charcoal injection method for the intraoperative visible identification of SLN was also evaluated. Methods  Twenty-five patients with invasive breast cancer were studied. Under ultrasonographic guidance, technetium-99m-labeled tin colloid particles (3 ml) were injected into 3 sites around the tumor within 3 mm of the margin or into the wall of the excisional biopsy cavity 2 hours before surgery. At surgery, just before the incision, an emulsion of charcoal particles (2.5 ml) was injected into 3 sites of the breast parenchyma surrounding the tumor. All patients underwent mastectomy with axillary dissection to the infraclavicular region. The radioactivity of each dissected lymph node was measured. All axillary specimens were processed in individual blocks for permanent section histopathologic evaluation with H &E. Results  SLN were defined as lymph nodes with 100 000 or more counts per minute (cpm) in radioactivity after injection of labeled tin colloids. In all 25 patients, SLN were identified (mean, 1.9 SLN/patient; range,l-4). Since the mean uptake in SLN was 383 124 cpm, but only 884 cpm in non-SLN nodes, discrimination between SLN and non-SLN nodes was easy. Clearly visible lymph nodes with charcoal staining accounted for 83.3% of all SLN, although 21.3% of non-SLN also stained. SLN were located only in the axillary region, but there were no other specific features in the location or size of SLN. The SLN were metastatic in 10 of the 25 patients: in 4, the SLN were the only metastatic nodes whereas in the remaining 6 patients, other axillary nodes were also positive. Fifteen patients with no metastasis in SLN had no tumor involvement in any other lymph nodes. There were no skip metastases. Conclusion  SLN identified with labeled tin colloids have clinical value in predicting the metastatic status of the remaining axillary lymph nodes in breast cancer.
