Abstract
BACKGROUND The recurrence of thyroid cancer poses challenges compounded by postoperative fibrosis and anatomic changes. By overcoming the limitations of current localizing dye techniques, indocyanine green-macroaggregated albumin-hyaluronic acid (ICG-MAA-HA) mixture dye promises improved localization. This study aimed to evaluate the efficacy and safety of the dye for recurrent thyroid cancer. METHODS The nine patients in this study underwent surgery and postoperative ultrasonography. The dye was injected into recurrent lesions in all the patients preoperatively. During surgery, the lesions were confirmed with an imaging system before and after excision. If the lesion was unidentifiable with the naked eye, surgical excision was performed under the corresponding fluorescent guide. Side effects related to the dye injection and completeness of the surgery were evaluated. RESULTS No side effects such as bleeding, skin tattooing, or pain during or after the dye injection were reported, and no discoloration occurred that interfered with the surgical field of view during surgery. In three cases (33.3 %), because it was difficult to localize metastatic lesions with the naked eye, the operation was successfully completed using an imaging system. The completeness of the surgical resection was confirmed by ultrasonography after an average of 5 months postoperatively. CONCLUSION The study found that ICG-MAA-HA dye effectively located metastatic and recurrent thyroid cancer and had favorable results in terms of minimal procedural side effects and potential for assisting the surgeon. A large-scale multi-institutional study is necessary to prove the clinical significance regarding patient survival and disease control.

Abstract
BACKGROUND Immune checkpoint blockade (ICB) elicits a strong and durable therapeutic response, but its application is limited by disparate responses and its associated immune-related adverse events (irAEs). Previously, in a murine model of lymph node (LN) metastasis, we showed that intranodal administration of chemotherapeutic agents using a lymphatic drug delivery system (LDDS) elicits stronger therapeutic responses in comparison to systemic drug delivery approaches, while minimizing systemic toxicity, due to its improved pharmacokinetic profile at the intended site. Importantly, the LN is a reservoir of immunotherapeutic targets. We therefore hypothesized that metastatic LN-targeted ICB can amplify anti-tumor response and uncouple it from ICB-induced irAEs. METHODS To test our hypothesis, models of LN and distant metastases were established with luciferase expressing LM8 cells in MXH10/Mo-lpr/lpr mice, a recombinant inbred strain of mice capable of recapitulating ICB-induced interstitial pneumonia. This model was used to interrogate ICB-associated therapeutic response and immune related adverse events (irAEs) by in vivo imaging, high-frequency ultrasound imaging and histopathology. qPCR and flowcytometry were utilized to uncover the mediators of anti-tumor immunity. RESULTS Tumor-bearing LN (tbLN)-directed CTLA4 blockade generated robust anti-tumor response against local and systemic metastases, thereby improving survival. The anti-tumor effects were accompanied by an upregulation of effector CD8T cells in the tumor-microenvironment and periphery. In comparison, non-specific CTLA4 blockade was found to elicit weaker anti-tumor effect and exacerbated ICI-induced irAEs, especially interstitial pneumonia. Together these data highlight the importance of tbLN-targeted checkpoint blockade for efficacious response. CONCLUSIONS Intranodal delivery of immune checkpoint inhibitors to metastatic LN can potentiate therapeutic response while minimizing irAEs stemming from systemic lowering of immune activation threshold.

Abstract
Background and Objectives The purpose of this study is to evaluate the relationship between lymph node status (the number of resected lymph nodes; the number of metastatic lymph nodes, LNM, and lymph node ratio, LNR) and biochemical recurrence, disease-free survival (DFS), as well as overall survival (OS) in medullary thyroid carcinoma (MTC). Methods This study enrolled MTC patients at Tianjin Medical University Cancer Institute and Hospital between 2011 and 2019. We used Logistic regression analysis, Cox regression models and Kaplan-Meier test to identify risk factors influencing biochemical recurrence, DFS, and OS. Results We identified 160 patients who satisfied the inclusion criteria from 2011 to 2019. We used ROC analysis to define the cut-off value of LNR with 0.24. Multifocality, preoperative calcitonin levels, pathologic N stage, resected lymph nodes, LNM, LNR, and the American Joint Committee on Cancer (AJCC) clinical stage were significant (P < 0.05) prognostic factors influencing biochemical cure. In univariable analyses, gross extrathyroidal extension, preoperative calcitonin levels, pathologic T classification, pathologic N stage, resected lymph nodes, LNM, LNR, AJCC clinical stage, and biochemical cure were significant (P < 0.05) factors of DFS. When the multivariable analysis was performed, LNR was identified as predictor of DFS (HR = 4.818, 95% CI [1.270-18.276]). Univariable Cox regression models reflected that tumor size, pathologic N stage, and LNR were predictor of OS. Furthermore, multivariable analysis manifested that LNR was predictor of OS (HR = 10.061, 95% CI [1.222-82.841]). Conclusions This study illustrated that LNR was independent prognostic factor of DFS and OS in MTC. In addition, LNR influenced biochemical cure. Further investigations are needed to determine the optimal cut-off value for predicting prognosis.

Abstract
Background Individuals with pN3 gastric cancer (GC) account for a large proportion of pN + GC, and exhibit poor survival outcomes. The pN3 stage is defined based upon the number of metastatic lymph nodes (mLNs), but the subclassification of pN3 patients based upon the number of examined LNs (eLNs) is rarely performed. Methods In total, 2894 pTxN3M0 GC patients in the Surveillance, Epidemiology, and End Results database that had undergone surgery from 2000 to 2016 were selected for analysis. The X-tile software was used to select the optimal cutoff values. Cox proportional regression analyses were used to evaluated hazard ratios corresponding to the risk of death. Selection bias was minimized via propensity score matching (PSM). Results As the number of eLNs rose, the risk of death for patients trended downwards. Survival analyses indicated that patients with ≤ 31 eLNs exhibited significantly poorer survival outcomes as compared to patients with > 31 eLNs (5-year OS: 18.4% vs. 24.7%), and this result remained significant when analyzing 857 pairs of patients following PSM analysis. Significant differences in prognosis were additionally observed when comparing pN3a and pN3b patients with ≤ 31 or > 31 eLNs under pT3/4a stage. For pT4b stage, pN3a patients with > 31 eLNs also exhibited a better prognosis than other patients. The novel TNM staging system designed exhibited excellent utility as a tool for the prognostic evaluation of this GC patient population. Conclusions These results suggest that in pN3 GC, a minimum of 32 LNs should be examined. The novel TNM staging system for pN3 patients described herein, which was developed based upon the number of eLNs, may thus be of value in clinical settings.

Abstract
OBJECTIVES The cause of cervical lymphadenopathy varies from inflammation to malignancy. Accurate and prompt diagnosis is crucial as delayed detection of malignant lymph node can lead to a worse prognosis. To improve the diagnostic accuracy of metastatic lymph node, electrical spectroscopy was employed to study human normal and metastatic lymph nodes using a hypodermic needle with fine interdigitated electrodes on its tip (EoN). SUBJECTS AND METHODS The electrical impedance of samples collected from 8 patients were analyzed in the sweeping frequency range from 1 Hz to 1 MHz. To align the impedance level data of the patients, normalized impedance was employed. RESULTS The optimal frequency exhibiting the best discrimination results between the normal and cancerous tissues was introduced based on a discrimination index. A high sensitivity (86.2%) and specificity (88.9%) were obtained, which implied that the EoN holds the potential to improve the in vivo diagnostic accuracy of metastatic lymph node during biopsy and surgery. CONCLUSION EoN has a promising potential to be utilized in real-time in actual clinical trials without a need for any pre/post-treatment during FNA or surgery. We believe that the EoN could reduce unnecessary operations with its associated morbidity.

Abstract
BACKGROUND Triple Negative breast cancer (TNBC) includes a heterogeneous group of tumors with different clinico-pathological features, molecular alterations and treatment responsivity. Our aim was to evaluate the clinico-pathological heterogeneity and prognostic significance of TNBC histologic variants, comparing "special types" to high-grade invasive breast carcinomas of no special type (IBC-NST). METHODS This study was performed on data obtained from TNBC Database, including pathological features and clinical records of 1009 TNBCs patients diagnosed between 1994 and 2015 in the four most important Oncology Units located in different hospitals in Sardinia, Italy. Kaplan-Meier analysis, log-rank test and multivariate Cox proportional-hazards regression were applied for overall survival (OS) and disease free survival (DFS) according to TNBC histologic types. RESULTS TNBC "special types" showed significant differences for several clinico-pathological features when compared to IBC-NST. We observed that in apocrine carcinomas as tumor size increased, the number of metastatic lymph nodes manifestly increased. Adenoid cystic carcinoma showed the smallest tumor size relative to IBC-NST. At five-year follow-up, OS was 92.1, 100.0, and 94.5% for patients with apocrine, adenoid cystic and medullary carcinoma, respectively; patients with lobular and metaplastic carcinoma showed the worst OS, with 79.7 and 84.3%, respectively. At ten-years, patients with adenoid cystic (100.0%) and medullary (94.5%) carcinoma showed a favourable prognosis, whereas patients with lobular carcinoma showed the worst prognosis (73.8%). TNBC medullary type was an independent prognostic factor for DFS compared to IBC-NST. CONCLUSIONS Our study confirms that an accurate and reliable histopathologic definition of TNBC subtypes has a significant clinical utility and is effective in the therapeutic decision-making process, with the aim to develop innovative and personalized treatments.

Abstract
BACKGROUND Preoperative detection of lymph node (LN) metastasis is critical for planning treatments in colon cancer (CC). The clinical diagnostic criteria based on the size of the LNs are not sensitive to determine metastasis using CT images. In this retrospective study, we investigated the potential value of CT texture features to diagnose LN metastasis using preoperative CT data and patient characteristics by developing quantitative prediction models. METHODS A total of 390 CC patients, undergone surgical resection, were enrolled in this monocentric study. 390 histologically validated LNs were collected from patients and randomly separated into training (312 patients, 155 metastatic and 157 normal LNs) and test cohorts (78 patients, 39 metastatic and 39 normal LNs). Six patient characteristics and 146 quantitative CT imaging features were analyzed and key variables were determined using either exhaustive search or least absolute shrinkage algorithm. Two kernel-based support vector machine classifiers (patient-characteristic model and radiomic-derived model), generated with 10-fold cross-validation, were compared with the clinical model that utilizes long-axis diameter for diagnosis of metastatic LN. The performance of the models was evaluated on the test cohort by computing accuracy, sensitivity, specificity, and area under the receiver operating curve (AUC). RESULTS The clinical model had an overall diagnostic accuracy of 64.87%; specifically, accuracy of 65.38% and 62.82%, sensitivity of 83.87% and 84.62%, and specificity of 47.13% and 41.03% for training and test cohorts, respectively. The patient-demographic model obtained accuracy of 67.31% and 73.08%, the sensitivity of 62.58% and 69.23%, and specificity of 71.97% and 76.23% for training and test cohorts, respectively. Besides, the radiomic-derived model resulted in an accuracy of 81.09% and 79.49%, sensitivity of 83.87% and 74.36%, and specificity of 78.34% and 84.62% for training and test cohorts, respectively. Furthermore, the diagnostic performance of the radiomic-derived model was significantly higher than clinical and patient-demographic models (p < 0.02) according to the DeLong method. CONCLUSIONS The texture of the LNs provided characteristic information about the histological status of the LNs. The radiomic-derived model leveraging LN texture provides better preoperative diagnostic accuracy for the detection of metastatic LNs compared to the clinically accepted diagnostic criteria and patient-demographic model.

Abstract
We evaluated the clinical and prognostic value of the protein expression of caveolin-1 (CAV1) and p16 at the primary site and metastatic lymph nodes of oral squamous cell carcinoma (OSCC). Primary site specimens from 80 OSCC cases were randomly selected and lymph node specimens from 15 preserved metastatic lymph nodes from among those patients were selected for examination. We evaluated the CAV1 and p16 expression at both the primary site and metastatic lymph nodes, and analyzed the patients' clinicopathological data in relation to CAV1 and p16 expression. Our analysis revealed significant positive correlations between CAV1 expression at the primary site and pathological metastasis, cell differentiation, and mode of invasion (p = 0.019, p = 0.002, p = 0.015, respectively), but p16 expression was not associated with any clinicopathological factors. Patients with high CAV1 expression at the primary sites showed significantly worse prognoses than those with low or negative CAV1 expression (p = 0.002), and multivariate analysis showed that the T classification and CAV1 expression were independent OSCC prognostic factors. CAV1 expression was also present in the metastatic lymph nodes of the OSCC cases with particularly poor differentiation and high invasive grade, and patients with CAV1-positive metastatic lymph nodes showed significantly worse prognoses than those with CAV1-negative metastatic lymph nodes (p = 0.018). CAV1 may activate metastaticity and the invasive capacity of OSCC cells. CAV1 expression, particularly at metastatic lymph nodes, predicts a worse outcome for OSCC, suggesting that CAV1 could be used as a prognostic marker for OSCC.

Abstract
PURPOSE To evaluate the safety and efficiency of microwave ablation (MWA) with low power of 20 w, respectively, in the treatment of cervical metastatic lymph node (CMLN) from papillary thyroid carcinoma (PTC) with a mean of 32-month follow-up. METHODS Eleven patients in total with 24 cervical lymph nodes (LNs) diagnosed with CMLN from PTC underwent MWA at a power of 20 w. We recorded images of the LNs under ultrasound first before MWA and 1, 3, 6, 12, months after MWA, and then every 6 months, respectively. The volumes of the LNs were compared before MWA and at each follow-up point after MWA. The thyroglobulin (Tg) test was performed before MWA and 3 months after MWA. RESULTS All patients were successfully treated, and they showed no major complications. Before MWA, the mean volume of the LNs was 364.15 ± 306.89 mm3, which decreased to 234.10 ± 230.34 mm3, 107.51 ± 129.47 mm3, 20.88 ± 39.27 mm3, 3.38 ± 12.74 mm3, and completely disappeared at the follow-up point of 1, 3, 6, 12, and 18 months after MWA, respectively. The mean Tg was 11.81 ± 7.50 ng/ml, a data significantly decreased to 0.43 ± 0.11 ng/ml 3 months after MWA (P = 0.000). In the follow-up period, no recurrent lesions were found. CONCLUSIONS For the treatment of CMLN from PTC, low power MWA showed good safety and efficacy. MWA is likely to be a candidate for patients with high risks or who refuse reoperation.

Abstract
BACKGROUND Current methods of lymph node (LN) staging are controversial in predicting the survival of SBA. We aimed to develop an alternative LN-classification-based nomogram to individualize SBA prognosis. METHODS Based on the data from the Surveillance, Epidemiology, and End Results (SEER) database of patients diagnosed with SBA between 2004 and 2014, we identified the cut-off points for the number of LNs examined and the number found to be metastatic using the K-adaptive partitioning (KAPS) algorithm. Using metastatic LNs, a nomogram predicting the survival of SBA was derived, internally and externally validated, and measured by calibration curve, C-index, and decision curve analysis (DCA), and compared to the 8th TNM stage. RESULTS A total of 1516 patients were included. The cut-off of 17 was the optimal examined LN number. For metastatic LN numbers, the cut-off points were 0, 2, and 8. The C-index for the nomogram was higher than the 8th TNM staging (internal: 0.734; 95% CI, 0.693 to 0.775 vs. 0.677; 95% CI, 0.652 to 0.702, P < 0.001; external: 0.715; 95% CI, 0.674 to 0.756 vs. 0.648; 95% CI, 0.602 to 0.693, P < 0.001). Also, the nomogram showed good calibration in internal and external validation and larger net benefit than TNM staging. CONCLUSION We modified current N staging into a 4-level staging system based on the number of metastatic LNs: N0, no LN metastasis; N1, 1-2 metastatic LNs; N2, 3-8 metastatic LNs, and N3, >8 metastatic LNs and set the least examined LN number to 17. A nomogram based on this staging showed great clinical usability than TNM staging for predicting the survival of SBA patients.

Abstract
OBJECTIVES Genetic profiles of primary and metastatic lung tumor have been investigated by previous studies. However, whether they can be replaced by each other to guide treatment remains controversial. Moreover, it is unclear that whether genetic profiles of plasma can reflect genetic divergence between primary and metastatic lesions. MATERIALS AND METHODS In this prospective study, we collected 35 pairs of matched primary tumor tissue, metastatic lymph nodes and plasma from treatment-naïve patients with advanced non-squamous non-small cell lung cancer (NSCLC) and applied to capture-based sequencing using a panel consisting 56 NSCLC-related genes to interrogate the heterogeneity and similarity among the 3 sites. RESULTS We observed 62.0% (67/108) by-variant concordance rate among primary tumor, metastatic lymph nodes and plasma as well as 76.4% (81/106) by-variant concordance rate between primary tumor and metastatic lymph nodes. When the analysis restricted to driver genes, we achieved 60.9% (28/46) and 77.3% (34/44) concordance, respectively. Furthermore, there is no statistically significant difference in progression-free survival (PFS) of 17 patients who used matched targeted therapy between patients having 100% concordance rate between primary tumor and metastatic lymph nodes and patients having partially matched mutational profiles. CONCLUSION Collectively, our study revealed a similar genetic profile shared between primary tumor and metastatic lymph nodes. The limited discordance observed can be partially reflected by plasma. Sequencing results obtained from either site can be utilized for providing treatment guidance.

Abstract
A 67-year-old man consulted our department with gross hematuria. Computed tomography (CT) revealed a huge renal tumor with a paracaval metastatic lymph node (mLN). Right total nephrectomy was planned for the renal tumor diagnosed as renal cell carcinoma preoperatively. Just before the resection of the renal vein and artery, intraoperative ultrasonography revealed an inferior vena caval tumor thrombus (IVCTT) extending from the mLN. Ultrasonography clearly and dynamically demonstrated a rhythmic flapping movement of the IVCTT with blood flow in the inferior vena cava. Following right radical nephrectomy, IVCTT resection with the vessel wall was performed to reduce the risk of pulmonary tumor thrombus. Histopathological diagnosis of the renal tumor was clear cell renal cell carcinoma, and the resected IVCTT was confirmed histopathologically as tumor involvement from the mLN of the renal cell carcinoma. Intraoperative ultrasonography can detect IVCTT extending from the mLN, whereas CT cannot.

Abstract
Aberrant histological elements have been infrequently reported to exist within the intact thyroid gland. In addition to distant metastases to the thyroid, a number of ectopic tissue rests and unusual cysts have been described within the thyroid gland. In this article, we report the presence of a true intrathyroid lymph node and describe the first reported case of intrathyroid lymph node metastasis of papillary thyroid cancer. Other reported aberrant intrathyroid tissues, possible pathophysiology, diagnostic features and surgical implications are also discussed.

Abstract
BACKGROUND The objective of this study was to evaluate the diagnostic performance of serum thyroglobulin (S-Tg), thyroglobulin in fine-needle aspiration washout (FNA-Tg) and fine-needle aspiration cytology (FNAC) in the detection of lateral metastatic lymph nodes (LNs) in patients with thyroid carcinoma. METHODS The study included 19 lateral metastatic LNs from 19 patients with thyroid carcinoma who underwent FNAC for the suspicion of metastatic disease on ultrasonogrphy (US). The S-Tg, FNA-Tg, FNAC, and histopathological results were correlated. RESULTS Compared with S-Tg, both FNAC and FNA-Tg showed higher sensitivity (89.5%, 89.5% versus 68.4%, respectively) and accuracy (89.5%, 89.5% versus 68.4%, respectively). The combined use of FNAC and FNA-Tg or FNAC and S-Tg showed superior diagnostic power. CONCLUSIONS S-Tg measurement is a less reliable method for follow-up in patients with thyroid carcinoma in comparison with FNA-Tg. For patients with negative S-Tg but suspicious features in US, FNAC combined with FNA-Tg is strongly recommended to confirm the diagnosis.

Abstract
BACKGROUND The BRAFV600E mutation is common in papillary thyroid cancer (PTC). Lymph node metastasis (LNM) may be associated with poor prognosis. However, the LNM mechanism remains unclear. OBJECTIVES Our aim was to evaluate the prevalence of the BRAFV600E mutation in primary tumors and accompanying LNM at the time of diagnosis. METHODS This retrospective study included 51 PTC patients (40 women, 11 men; mean age 40.0 ± 16.5 years; range 6-81) who underwent total thyroidectomy accompanied by a lateral neck dissection due to preoperatively detected LNM. Real-time PCR was used for the detection of the BRAFV600E mutation in specimens from primary thyroid tumors and metastatic lymph node tumors. RESULTS The prevalence of the BRAFV600E mutation was 64.7% (n = 33) in primary tumors and 47.1% (n = 24) in metastatic lymph nodes. Of 33 patients with BRAFV600E-positive primary tumors, 18 (54.5%) had BRAFV600E-positive metastatic lymph nodes. Of 18 patients with BRAFV600E-negative primary tumors, 6 (33.3%) had BRAFV600E-positive metastatic lymph nodes. The presence of the BRAFV600E mutation in the primary tumor did not affect the tumor size, but the diameter of metastatic lymph nodes significantly increased (by nearly 3 mm) with the presence of BRAFV600E in LNM (p = 0.01). CONCLUSIONS In our study, the BRAFV600E mutation did not show a one-to-one correspondence. This indicates that the presence of BRAFV600E in the primary tumor is not clonal and addresses the role of intratumor heterogeneity in PTC tumorigenesis. This supports the theses that mutations occur in the later stages of tumorigenesis, might be subclonal, and develop de novo, or that some other factors may be involved in the development of metastasis.

Abstract
PURPOSE To evaluate by a meta-analytic approach the long-term prognostic impact of para-aortic lymph node (PALN) involvement in resected ductal adenocarcinoma of the pancreas. METHODS MEDLINE, Embase, PubMed and the Cochrane Library were searched from January 1990 to June 2015. Trials reporting Kaplan-Meier curves and comparing overall long-term survival of negative and metastatic PALN in patients who underwent resection for pancreatic cancer were included. Lymph nodes were classified according to the Japan Pancreatic Society rules and identified using hematoxylin and eosin staining. Hazard ratios (HRs) and 95%CI were estimated for each trial and pooled in a meta-analysis. RESULTS Thirteen eligible studies including 2141 patients (364 positive PALN; 1777 negative PALN) were identified. Most of the studies were retrospective. Heterogeneity among trials was high (I(2) = 98.7%; p < .001). PALN metastasis was associated with increased mortality when compared with patients with negative PALN regardless regional nodal status [HR 1.85, 95%CI 1.48-2.31; p < .001]. Median survival was significantly decreased in patients with positive PALN (WMD = -4.92 months 95%CI -6.40; -3.43; p < .001). Moreover, metastatic PALN affected mortality also when regional lymph nodes were positive [HR 1.67, 95%CI 1.34-2.08; p < .001]. No publication bias was detected. CONCLUSIONS PALN metastasis appears to correlate with poor prognosis in patients with pancreatic adenocarcinoma. The assessment of PALN status may be considered for a more accurate staging of the disease and appropriated subgroup survival reporting. However, the definitive avoidance of the resection in case of intraoperative metastatic PALN needs further investigation.

Abstract
AIM: To investigate the effect of preoperative chemotherapy (pre-CTx) for metastatic lymph nodes (MLNs) of gastric cancer (GC).
METHODS: A retrospective cohort of patients with advanced GC, who underwent pre-CTx followed by gastrectomy, was reviewed. The histological tumor regression grade (TRG), which considered the percentage of residual cancer in the visible tumor bed, was applied to primary tumors and individual MLNs: G1a (complete response), G1b (< 10%), G2 (10%-50%) and G3 (> 50%). The clinical response to pre-CTx was retrospectively evaluated using only MLNs information, and we compared the histological and clinical evaluations of MLNs.
RESULTS: Twenty-eight patients were enrolled. A total of 438 MLNs were retrieved, and 22 (5%), 48 (11%), 63 (14%) and 305 (70%) LNs were assigned as G1a, G1b, G2 and G3, respectively. Stratification of the residual MLNs based on the TRGs was as follows: 28 G1b MLNs (9%), 48 G2 MLNs (15%), and 253 G3 MLNs (76%) in the D1 region; 20 (23%), 15 (17%), and 52 (60%) in the D2 region, respectively. However, no significant correlation was found between TRGs in MLNs and clinical response in the subgroup for which evaluation of clinical response was available.
CONCLUSION: Pre-CTx does not provide any outstanding histological benefit for MLNs, and an appropriate D2 lymphadenectomy should routinely be performed to offer the chance of curative resection.

Abstract
BACKGROUND Definitive chemoradiotherapy (CRT) is used to treat lymph node metastatic head and neck cancer patients. Regional control of the neck disease is important to improve the prognosis, and the accuracy of the method used to evaluate the metastatic lymph node(s) after CRT is crucial to the decision-making process for any following salvage surgery. METHODS Patients undergoing CRT were divided in two groups of patients of those showing complete clinical response (CR) and those showing clinical non-response (non-CR), as assessed by computed tomography (CT) and/or magnetic resonance imaging (MRI), ultrasonography, fluorodeoxyglucose-positron emission tomography (FDG-PET), and fine needle aspiration cytology. The responses (CR vs. non-CR) were compared with the actual clinical outcomes. For the interim analysis, the study period was broken down into two periods, namely, the exploratory phase (patients treated between January 2002 and April 2012) and the validating phase (patients treated between May 2012 and January 2014). RESULTS The sensitivity, specificity, and accuracy were as follows: CT and/or MRI, 66.7, 73.8, and 72.8 %, respectively, in the exploratory phase; ultrasonography, 91.7, 70.6, and 73.4 %, respectively, in the exploratory phase and 80.0, 82.8, and 82.4 %, respectively, in the validating phase; FDG-PET, 50.0, 97.5, and 91.3 %, respectively, in the exploratory phase and 60.0, 100, and 94.1 %, respectively, in the validating phase; cytology, 68.4, 95.9, and 90.3 %, respectively, in the exploratory phase and 66.7, 100, and 85.7 %, respectively, in the validating phase. CONCLUSIONS Based on our results, CT and/or MRI appear to be inadequate methods for the evaluation of the response of lymph node(s) to CRT. In contrast, ultrasonography appears to be a highly sensitive and useful tool for positive screening at 6-8 weeks after CRT, and FDG-PET appears to be a highly specific and useful tool for negative screening at 8-12 weeks after CRT.

Abstract
AIM: To investigate the prognostic value of metastatic lymph node ratio (MLNR) in extrahepatic cholangiocarcinoma (ECC) patients undergoing radical resection.
METHODS: Seventy-eight patients with ECC were enrolled. Associations between various clinicopathologic factors and prognosis were investigated by Kaplan-Meier analyses. The Cox proportional-hazards model was used for multivariate survival analysis.
RESULTS: The overall three- and five-year survival rates were 47.26% and 23.99%, respectively. MLNR of 0, 0-0.2, 0.2-0.5, and > 0.5 corresponded to five-year survival rates of 28.59%, 21.60%, 18.84%, and 10.03%, respectively. Univariate analysis showed that degree of tumor differentiation, lymph node metastasis, MLNR, tumor-node-metastasis (TNM) stage, and margin status were closely associated with postoperative survival in ECC patients (P < 0.05). Multivariate analysis showed that MLNR and TNM stage were independent prognostic factors after pancreaticoduodenectomy (HR = 2.13, 95%CI: 1.45-3.11; P < 0.01; and HR = 1.97, 95%CI: 1.17-3.31; P = 0.01, respectively). The median survival time for MLNR > 0.5, 0.2-0.5, 0-0.2, and 0 was 15 mo, 24 mo, 23 mo, and 35.5 mo, respectively. There were statistical differences in survival time between patients with different MLNR (χ2 = 15.38; P < 0.01).
CONCLUSION: MLNR is an independent prognostic factor for ECC patients after radical resection and is useful for predicting postoperative survival.

Abstract
OBJECTIVES To investigate prognostic values of maximum standardized lymph node (LN) uptake (SUVmax), minimum apparent LN diffusion coefficient (ADCmin), and LN short-axis length in women with cervical cancer. STUDY DESIGN Retrospective review of diffusion-weighted magnetic resonance imaging (DWI) and positron emission tomography/computed tomography (PET/CT) of LN confined to the pelvis in 80 cervical cancer patients before undergoing radiotherapy (RT) with or without concurrent chemotherapy. Optimal cut-off values for disease-free survival (DFS) and overall survival (OS) were determined by receiver operating characteristic (ROC) curve analysis. We used ROC curve analyses to evaluate whether LN SUVmax, LN ADCmin and LN short-axis length predicted risk of recurrence or survival. RESULTS Median DFS and OS for all patients were 18.97 and 22.28 months, respectively. DFS and OS rates of patients with high LN SUVmax was significantly lower than those of patients exhibiting low LN SUVmax (P=0.003 and P=0.019). Patients with low LN ADCmin had poorer DFS and OS than those with high LN ADCmin (P=0.033 and P=0.005). DFS for patients exhibiting longer LN short-axis length was significantly lower than those of patients exhibiting shorter LN short-axis length (P=0.018). Multivariate analyses indicated that high LN SUVmax was an independent predictor for both DFS and OS (P=0.0231 and P=0.0146). CONCLUSIONS LN SUVmax could be an important predictor of recurrence and survival in patients with cervical cancer confined to the pelvis.

Abstract
INTRODUCTION Pure squamous cell carcinoma of the breast [SCCB] is rare. PRESENTATION OF CASE We report a case of primary squamous cell carcinoma of breast with ipsilateral axillary lymph node metastasis in a 58year old woman. DISCUSSION It is a breast carcinoma entirely composed of metaplastic squamous cells that may be keratinized, non-keratinized or spindled. The pure squamous cell carcinoma usually present with central cystic cavity, which we found in our case, also supported by immunohistochemical evidence. CONCLUSION Although a rare breast cancer subtype, SCCB is of considerable interest due to its pathological heterogeneity and differences in clinical behavior and less reported occurrence of nodal metastasis.

Abstract
AIM: To investigate the re-expression of E-cadherin (E-cad) in metastatic lymph node of advanced colorectal carcinoma and its clinical importance.
METHODS: The expression of E-cad in 32 specimens of primary colorectal carcinoma and metastatic lymph nodes was examined by means of immunohistochemistry, Western blot and RT- PCR to analyze the mechanism behind the re-expression of E-cad in metastatic lymph nodes.
RESULTS: The abnormal expression rate of E-cad in primary colorectal carcinoma was 90.6% (29/32), and the re-expression rate of E-cad in metastatic lymph nodes was 37.5% (12/32). The re-expression rate of E-cad in metastatic lymph nodes was significantly higher in patients with well/moderately differentiated carcinoma than in those with poorly differentiated carcinoma (55.6% vs 14.3%, P < 0.05). Western blot analysis showed that the relative expression intensity of E-cad in metastatic lymph nodes was higher than that in primary carcinoma (P < 0.05). The relative expression intensity of E-cad protein in metastatic lymph nodes was significantly higher in patients with well/moderately differentiated adenocarcinoma than in those with poorly differentiated adenocarcinoma (98.56 ± 36.09 vs 66.21 ± 29.74, P < 0.05). The relative expression intensity of E-cad protein in metastatic lymph nodes is correlated with tumor histological type. RT-PCR analysis showed that the relative expression level of E-cad mRNA in primary carcinoma was significantly lower than that in metastatic lymph nodes and normal mucosal tissue (0.733 ± 0.009 vs 0.739 ± 0.010 and 0.796 ± 0.016, both P < 0.05). The re-expression of E-cad mRNA in metastatic lymph nodes is associated with tumor differentiation degree and tumor histological type (both P < 0.05).
CONCLUSION: E-cad expression shows characteristic changes during the development and progression of colorectal cancer. E-cad is a possible new target for diagnosis and treatment of colorectal cancer.
