457 Background: The prognosis of intrahepatic cholangiocarcinoma (ICC) with lymph node metastases is dismal. Recent studies have highlighted the importance of lymph node retrieval from disease staging and therapeutic standpoints. To define the role of lymph node dissection for ICC, this study aimed to evaluate the patterns of lymph node metastases and their prognostic implication. Methods: A retrospective cohort analysis was conducted for 56 consecutive patients who underwent R0/R1 resection for ICC between 1990 and 2015. In principle, lymph nodes in the hepatic hilum and around the pancreas head were systematically removed. For left-sided tumors, lymph nodes in the lesser curvature of the stomach and the root of left gastric artery were also dissected. Clinicopathologic predictors of 3-year survival were identified by Cox multivariate analyses. Lymph node mapping was performed and positive nodes were classified into 3 compartments based on metastatic rates and prognoses. Results: Median tumor size, 4.5 (1.5–16.0) cm; Mass-forming and its dominant type, 42 (75%); R0 resection, 47 (84%). Nineteen (34%) patients had lymph node metastases. After excluding 4 in-hospital deaths, the overall and recurrence-free survival rates at 3 years were 66% and 33%, respectively (median follow-up, 36 months). Cox multivariate analysis revealed lymph node metastases [hazard ratio (HR) 6.3, 95% confidence interval (CI) 1.9-21.7, P = 0.003] and R1 resection (HR 7.8, 95% CI 1.6-38.3, P = 0.01) as independent negative predictors of overall survival. Patients with ≥ 4 positive nodes ( n = 7) had significantly decreased survival compared with those with 1–3 positive nodes ( n = 10, P= 0.005). Metastatic lymph nodes were classified into compartments I (metastatic rates ≥ 10% and longest survival ≥ 3 years), II (5%–10% and 1-year survival ≥ 50%), and III ( < 5% and 1-year survival < 50%). Lymph nodes in the suprapyloric area, celiac trunk, and paraaorta belonged to compartment III and appeared less important to be dissected. Conclusions: Systematic lymph node dissection for ICC based on tumor location provides accurate staging and may prolong survival in patients with limited number of positive nodes. Compartment classification is useful to determine the extent of dissection.

Thymic Tumors

Thymic tumors are the most common primary neoplasms of the anterior mediastinum, although, when compared with the entire thoracic malignancies, they are still rare. Few studies addressed the questions about lymph node involvement pattern in thymic neoplasms, about which subgroup of patients would be appropriate candidates for lymph node dissection or about the extent of lymphadenectomy or which lymph nodes should be harvested. The aim of this review is to collect evidence from the literature to help physicians in designing the best surgical procedure when dealing with thymic malignancies. A literature review was performed through PubMed and Scopus in May 2021 to identify any study published in the last 20 years evaluating the frequency and the extent of lymph node dissection for thymic tumors, its impact on prognosis and on postoperative management. Fifteen studies met the inclusion criteria and were included in this review, with a total of 9452 patients with thymic cancers; lymph node metastases were found in 976 (10.3%) patients in total. The current literature is heterogeneous in the classification and reporting of lymph node metastases in thymic carcinoma, and data are hardly comparable. Surgical treatment should be guided by the few literature-based pieces of evidence and by the experience of the physicians.

Abstract Background Lymph node dissection (LND) is of great significance in intrahepatic cholangiocarcinoma (ICC). Although the National Comprehensive Cancer Network (NCCN) guidelines recommend routine LND in ICC, the effects of LND remains controversial. This study aimed to explore the role of LND and some related issues and of in ICC. Methods Patients were identified in two Chinese academic centers. Inverse probability of treatment weighting (IPTW) was used to reduce bias. Kaplan–Meier curves and Cox proportional hazards models were used to compare overall survival (OS) and disease-free survival (DFS). Results Of 232 patients, 177 (76.3%) underwent LND, and 71 (40.1%) had metastatic lymph nodes. A minimum of 6 lymph nodes were dissected in 66 patients (37.3%). LND did not improve the prognosis of ICC. LNM > 3 may have worse OS and DFS than LNM 1–3, especially in the LND >  = 6 group. For patients who did not underwent LND, the adjuvant treatment group had better OS and DFS. Conclusions The proportions of patients who underwent LND and removed >  = 6 lymph nodes were not high enough. LND has no definite predictive effect on prognosis. Patients with 4 or more LNMs may have a worse prognosis than patients with 1–3 LNMs. Adjuvant therapy may benefit patients of nLND.

Lymph node dissection in colon cancer is without a doubt necessary, it is just the extent of that dissection that is still under debate. As the individual steps of an oncologic operation cannot be separated from each other, analysis of the significance of lymph node dissection alone is difficult. It has been proven that the T category is directly related to the number and central spread of lymph node metastases. Micrometastases and isolated tumor cells may be detected in lymph nodes by using special staining techniques; their presence may worsen prognosis significantly and approximate it to UICC stage III. The numbers of dissected lymph nodes and the ratio of involved versus dissected lymph nodes have been used as markers for quality of surgery and histopathological evaluation.

Node Metastases

A series of 45 recurrences in the soft tissues of the neck following lymph node dissection in 497 patients bearing carcinoma of the upper aerodigestive passages is reported. Only 22 cases that presented perilymph node metastases and/or in which there were reasons to indicate insufficient surgical radicality had been subjected to radiotherapy after surgical lymph node dissection; the other 23 cases had not been subjected to radiotherapy because the aforementioned premises had been lacking. All the recurrences therefore occurred in patients with clinically and histologically ascertained metastatic lymph nodes. The presence of perilymph node metastases and the judgement of surgical radicality was thus found insufficient criteria to plan future complementary postoperative radiotherapy. However, even in those cases in which postoperative radiotherapy was performed, there was a rather high incidence of recurrences, as high as 64.7% in patients with carcinoma of the tongue. Our data indicate the opportunity of a clinical trial with preoperative radiation therapy in patients with clinically evident lymph node metastases. Thirty-six of these recurrences were situated in the upper parts of the cervical region. The prognosis is very poor in such cases, so much so that only 2 of our series were disease free at 3 years after the treatment.

Abstract Aim We sought to evaluate the safety and oncological efficacy of bilateral recurrent laryngeal nerve (RLN) lymph node dissection (LND) in patients with esophageal squamous cell carcinoma (ESCC) who had undergone neoadjuvant chemoradiotherapy (nCRT). Methods The need to dissect RLN lymph nodes in patients who had undergone nCRT is controversial. No data are currently available on the clinical utility and implications of RLN nodal dissection in nCRT-treated patients with esophageal cancer. We retrospectively examined the records of ESCC patients who were judged to be ycN-RLN(-) following nCRT. Patients were divided into two groups according to the extent of LND (standard two-field LND [STL group] versus total two-field LND [TTL group]). Only lower mediastinal and upper abdominal lymph nodes were removed in the STL group. In addition to the standard procedure, patients in the TTL group underwent resection of upper mediastinal lymph nodes located along the bilateral RLN. Using propensity score matching, 29 pairs were identified and compared with regard to perioperative complications, lymph node metastases rates, overall survival (OS), and disease-specific survival (DSS). Results No significant intergroup differences were identified in terms of in-hospital mortality and morbidity. Metastases to the RLN lymph nodes were identified in 20.7% (6/29) of TTL patients, being the only site of lymph node metastases in three of them. TTL was associated with lower upper mediastinal lymph node recurrence rate(6.5%) compared with STL (21.5%, p=0.134), although the overall recurrence rate was similar (STL, 44.8% versus TTL, 46.4%). No significant intergroup differences were also evident with regard to 3-year DSS and OS rates. Conclusions RLN LND can be safely performed in ESCC patients who had undergone nCRT, ultimately resulting in an improved local control and should be practiced as part of the surgical routine.
