Abstract：

Objective To explore the risk factors of inguinal metastasis in squamous cell carcinoma of the penis, screening lymph node metastasis high-risk patients. Methods The clinical and pathological data of 81 consecutive patients with squamous cell carcinoma of the penis were analyzed retrospectively. Age at presentation ranged from 27 to 81 years with a median of 49 years. Course of disease within one year of patients with 46 cases (56.8%), 1 year above 35 eases (43.2 %). Seventyfive patients underwent bilateral inguinal lymph node dissection, and 6 patients had unilateral inguinal lymph node dissection. Clinical stage of the primary tumor was assigned according to the 2002 TNM staging system. Variables included patients' age, redundant prepuce and/or phimosis, tumor site,size, number, macroscopic growth pattern, histological grade, inguinal physical examination and the size of inguinal lymph nodes. Results Of the 81 patients, 42 (51.9%) were staged as pN+ and 39 (48. 1%) as pN0. Metastases occurred in 32.0% (16/50) of G1, 78.3% (18/23) of G2 and 100. 0%(8/8) of G3 cases, with significant differences among them (P= 0. 015). According to the inguinal lymph node physical examination results, 63 were staged as clinically node-positive (cN+) and 18 as clinically node-negative (cN0). Metastases occurred in 63. 5% (40/63) of cases of cN+, as compared with 11.1% (2/18) of cases of cN0(P=0. 012). At a median follow up of 40 months (ranged 2-127 months), the 5-year disease free survival rates for positive and negative inguinal lymph nodes metastasis were 71.4% and 92.3%, respectively (P=0. 005) , and the 5-year cancer specific survival rates were 79.0% and 91.4%, respectively (P=0.001). Conclusions Inguinal physical examination and histological grade were the strongest predictors of inguinal metastasis. The patients with inguinal lymph nodes metastasis have lower 5-year disease free survival rates and cancer specific survival rates,and should receive positive treatment measures.

Appraisal of surgical resection of gallbladder cancer with special reference to lymph node dissection

BACKGROUND: Radical lymph node dissection in surgery for advanced gallbladder cancer is controversial. The purpose of this study is to evaluate the role of lymph node dissection based on the clinico-pathologic results. PATIENTS: Seventy-three patients who underwent radical surgery including systematic dissection of the N1+N2 region lymph node plus some of the para-aortic nodes were reviewed. RESULTS: pT1 patients had no lymph node metastasis, but pT2 and pT3/pT4 patients had lymph node metastasis at a rate of 50.0% (13/26) and 83.3% (25/30), respectively. As infiltration of the hepatoduodenal ligament (Binf) became severe, the rate and extent of lymph node metastasis increased. There were four 5-year survivors with lymph node involvement. The 5-year survival rates are 77.0% in pN0 cases and 27.3% in pN1 cases (P<0.01). There was no difference in survival between pN1 and pN2 patients. However, significant differences in survival were observed between pN0/1 and pN2/3 patients when these patients were limited to Binf0/1. Examination of the recurrence pattern showed that most patients with pN0/1/2 had no regional lymph node recurrence, but there was para-aortic lymph node recurrence in patients with pN3 outside the dissected region. Significant prognostic factors influencing survival after surgery by multivariate analysis were pN2/3, pT, and residual tumor. CONCLUSION: Systematic lymph node dissection of N1, N2, and part of the para-aortic region improves survival in advanced gallbladder cancer patients, especially in those without either para-aortic lymph node metastases or Binf2/3.     

Prognostic significance of the number of positive lymph nodes in gallbladder cancer

The aim of this study was to assess the prognostic impact of the number of lymph node metastases. The medical records of 33 patients with node-positive gallbladder cancer (GBC) treated at our institution from January 1985 through December 2002 were reviewed. There were 10 cases with a single node metastasis. The sites were as follows: the cystic duct node, the pericholedochal node, the retroportal node, the hilar node, the lymph node around the common hepatic artery, and the paraaortic node. According to the International Union Against Cancer (UICC) 5th edition, 5-year survival rates for the patients with pN1, pN2, and greater than pN2 were 19.2%, 10%, and 0%, respectively (not significant). Patients with a single node metastasis had a higher 5-year survival rate (33%) than patients with two or more lymph node metastases (0%; P<0.05). There were no lymph node recurrences in patients with a single node metastasis. Number of positive nodes and liver metastasis were factors predictive of significantly worse survival. Rather than using the topographic classification, or even simply classifying whether nodal involvement is positive or negative, classification according to the number of positive nodes will contribute to establishing a more practically useful staging system.     

Significance of Extensive Surgery Including Resection of the Pancreas Head for the Treatment of Gallbladder Cancer—From the Perspective of Mode of Lymph Node Involvement and Surgical Outcome

The present study aimed to clarify the efficacy of extensive surgery, including pancreas head resection, for more complete lymphadenectomy in the treatment of gallbladder carcinoma. The study involved retrospective analyses of 65 consecutive patients with gallbladder carcinoma who underwent surgical resection between 1982 and 2003. Of these 65 patients, 41.5% displayed node-positive disease and among them 23.1% had positive para-aortic nodes. Of six node-positive 5-year survivors, five underwent pancreatoduodenectomy combined with S4aS5 hepatic subsegmentectomy. The 5-year survival rates were 76.2% for pN0, 30.0% for pN1, 45.8% for pN2, and 0% for pM1[lymph], respectively. Significant differences existed in survival rates. Postoperative recurrence was observed in 24.1% (13/54) of patients who underwent R0 resection. Of the four patients who displayed lymph node recurrence, two had pericholedocal and/or posterior pancreatoduodenal lymph node metastasis at the time of surgery and underwent pancreas-preserving regional lymphadenectomy. These results suggest that extensive resection, including resection of the pancreatic head, is effective in selected patients with up to pN2 lymph node metastasis, as long as complete removal of the cancer can be achieved. Pancreatoduodenectomy combined with S4aS5 hepatic subsegmentectomy should be considered when lymph node metastasis is obvious and the patient is in good condition.     

Oncologic outcomes of laparoscopic radical nephroureterectomy in conjunction with template-based lymph node dissection: An extended follow-up study

ObjectivesThis study investigated the relapse pattern and oncologic outcomes after laparoscopic nephroureterectomy with template-based lymph node dissection (LND) in patients with clinically node-negative (cN0) upper urinary tract urothelial carcinoma. The frequency of lymph node metastasis, including micrometastases, was also evaluated.Methods and materialsA total of 105 patients with cTa-3N0M0 upper urinary tract urothelial carcinoma were analyzed, all of whom underwent regional LND during laparoscopic nephroureterectomy. Of those patients, 96 (91%) underwent complete LND in accordance with an anatomical template-based rule. We collected patient characteristics, pathological data, and follow-up data from medical charts. Micrometastases were assessed by pan-cytokeratin immunohistochemistry. Nonurothelial recurrence-free survival and cancer-specific survival were estimated using the Kaplan–Meier method.ResultsThe median number of lymph nodes removed was 12 (range, 1–59). Lymph node metastasis was identified by routine pathological examination in 7 (7/105, 6.7%) patients. Pan-cytokeratin immunohistochemistry revealed micrometastases in 5 additional patients (pNmicro +: 5/105, 4.8%). Nonurothelial disease recurrence was observed in 21 (20%) patients at a median of 10 months (range: 1–33) after surgery. Distant metastasis was dominant (15/105, 14.3%), followed by locoregional recurrence (5/105, 4.8%) and both (1/105, 0.95%). The 5-year nonurothelial recurrence-free survival rates were 84.8% for pN0, 53.3% for pNmicro+, and 19.1% for pN+ (3-sample log-rank test, P < 0.0001). The 5-year cancer-specific survival rates were 95.0% for pN0, 53.3% for pNmicro+, and 23.8% for pN+ (P < 0.0001).ConclusionsOur observation showed that template-based LND could contribute to precise disease staging and better local disease control probably by eliminating nodal disease, compared with previous studies. The survival impact and ideal management of pNmicro+ disease should be evaluated in a larger cohort.     

一种新的胃癌淋巴结分期方案

目的比较AJCC/UICC 1997年第五版胃癌TNM分期中的N分期与以淋巴结转移度为标准的新N分期. 方法行D2或D3术式的胃癌(皆无远处转移)标本用透光法摘取淋巴结,分别按2种方法分期,新法中N1为淋巴结转移度0.01%～10.00%, N2为10.01%～25.00%,N3为＞25.00%.全组随访,资料经统计学处理. 结果本组78例患者共取得淋巴结5388 枚,平均每例69枚(范围30～157枚).全组淋巴结转移率75.64%(59/78).新分期N0、N 1、N2、N3期患者3年生存率分别为100%、68.42%、7.58%、6.78%(χ2=35.85 0,P<0.01, r=0.95). 结论淋巴结转移度是一相对数,在预后的判断上,优于淋巴结转移数目.     

Oncological issues in staging mediastinal lymph node metastasis for left lung cancer

ObjectiveWe aimed to discuss the underlying oncological issues in staging of mediastinal lymph node metastasis in patients with left lung cancer who underwent extended radical lymphadenectomy (ERL).MethodsThis multi-institutional retrospective study analyzed 116 patients with left non-small-cell lung cancer who underwent bilateral paratracheal lymph node dissection (ERL) via median sternotomy. The clinicopathological records of patients with mediastinal lymph node metastasis were examined for prognostic factors, including age, sex, histology, tumor size, cN number, preoperative data, metastatic stations (number and distribution), pT, and adjuvant chemotherapy.ResultsMediastinal lymph node metastases were found in 43 patients, and right paratracheal lymph node metastases (pN3) were found in 13 patients. The 5-year overall survival rate was 25.2% in patients with pN3 tumors (n = 13) and 23.1% in patients with pN2 tumors (n = 30). The prognosis did not differ between patients with pN3 and pN2. Univariate analyses showed that histology, cN, and adjuvant chemotherapy were significant prognostic factors in patients with mediastinal lymph node metastasis. In these 43 patients, cN and adjuvant chemotherapy were significant independent prognostic factors in multivariate analysis.ConclusionsThe prognostic factors for left lung cancer with mediastinal lymph node metastasis were cN status and adjuvant chemotherapy, and not pN status (pN2 or pN3). We hope that the study results, which suggest that there may be no difference in prognosis between pN2 and pN3, would broaden the discussion of oncological issues in the staging of mediastinal lymph node metastasis of left lung cancer.     

Prognostic Factors for Surgically Resected N2 Non-small Cell Lung Cancer

Purpose: Non-small cell lung cancers (NSCLCs) with pathologically documented ipsilateral mediastinal lymph node (LN) metastases (pN2) are a broad spectrum of diseases. We retrospectively analyzed prognostic factors for cases of pN2 NSCLC treated by surgical resection.Methods: Clinicopathological data were reviewed for consecutive 121 patients who underwent anatomical pulmonary resection with mediastinal LN sampling or dissection for pN2 NSCLC over a 15-year period.Results: The 5-year survival rate for all patients was 29.9%. Clinical N status, curability, surgical procedure and adjuvant chemotherapy were favorable prognostic factors in univariate analysis, with 5-year survival rates of 35.0% for cN0/1 vs. 17.7% for cN2/3 cases; 33.1% for R0 vs. 14.7% for R1/2 resection; 31.5% for lobectomy vs. 25.0% for bilobectomy and 15.6% for pneumonectomy; and 72.7% with adjuvant chemotherapy vs. 23.8% without adjuvant chemotherapy. Survival did not differ significantly based on gender, age, smoking status, clinical T status, tumor location, histology, skip metastasis, subcarinal LN metastasis, or number of involved N2 levels. In multivariate analysis, adjuvant chemotherapy, R0 resection, and lobectomy emerged as independent favorable prognostic factors.Conclusion: Complete resection using lobectomy and adjuvant chemotherapy are favorable prognostic factors in cases of pN2 NSCLC.
