Abstract Background Pancreaticoduodenectomy is the only definitively curative therapy for the long-term survival of distal cholangiocarcinoma patients. Lymph node metastasis is widely accepted as an important prognostic factor for distal cholangiocarcinoma. The latest American Joint Committee on Cancer (AJCC) TNM classification system for distal cholangiocarcinoma has divided the lymph node metastasis patients into N1 and N2 by lymph node metastasis number. However, some studies suggested that the lymph node metastasis ratio may be better than the lymph node metastasis number. Therefore, we develop a program to analyze the correlation between lymph node parameters (lymph node dissection number, lymph node metastasis number, and lymph node metastasis rate) and long-term prognosis. Methods We retrospectively reviewed 123 distal cholangiocarcinoma patients after pancreatoduodenectomy from January 2011 to December 2019. The patients were grouped according to lymph node metastases and tumor-free and overall survival rates which were investigated with the Kaplan-Meier analysis. The logistic regression models were used for multivariate analysis to determine the risk factors for lymph node metastases. And the X-tile program was used to calculate the cutoff values for the lymph node parameters that discriminated survival. Results The 1-year, 3-year, and 5-year overall survival rates of patients with distal cholangiocarcinoma after pancreatoduodenectomy were 75.2%, 37.1%, and 31.5%, respectively. And the 1-year, 3-year, and 5-year overall survival rates of patients without and with lymph node metastasis were 83.0%, 50.7%, and 42.5% and 63.5%, 19.0%, and 19.0% (p = 0.000), respectively. Logistic regression showed CA19-9 and portal vein system invasion as independent risk factors for lymph node metastases. The receiver operating characteristic curve showed the optimal cutoff value of CA19-9 to predict the lymph node metastases was 75.5 U/mL. Determined by the X-tile software, the optimal cutoff values of the lymph node dissection number were 24 (p = 0.021), the lymph node metastasis number were 1 and 7 (p = 0.504), and the lymph node metastasis rate were 0.13 (p = 0.002). Conclusion Lymph node metastasis is an important factor affecting the long-term survival of distal cholangiocarcinoma patients.CA19-9 and portal vein system invasion are independent risk factors for lymph node metastasis. Besides, the lymph node dissection number and lymph node metastasis rate can predict the long-term survival better than lymph node metastasis number.

BackgroundPapillary thyroid micro-carcinoma (PTMC) is defined as a tumor with a larger diameter ≤1 cm which has an indolent course and satisfying prognosis. However, the incidence of lymph node metastasis of PTMC cannot be ignored. The aim of this study was to assess the incidence of lymph node metastasis in PTMC patients, as well as to evaluate the risk factors for both central lymph node metastases (CLNM) and lateral lymph node metastases (LLNM).MethodsPatients who underwent thyroidectomy from January 2017 to October 2020, and pathologically diagnosed with PTMC were enrolled in our study and their medical records were collected and analyzed.ResultsA total of 484 PTMC patients were included. The incidence of central and lateral lymph node metastasis was 49.6% and 9.1%, respectively. Multivariate analysis demonstrated as independent risk factors for CLNM male sex, age <40 years, largest tumor size ≥5 mm and bilaterality. Extrathyroidal extension, presence of CLNM, number of CLNM ≥5 were strong indicators for LLNM.ConclusionThe incidence of lymph node metastases in PTMC is non-negligible. The identification of potential risk factors for CLNM and LLNM would help tailor individual surgical interventions for patients with PTMC.

Objectives: The aim of this study was to assess the number of tumour-infiltrating lymphocytes (TILs) and the expression of Programmed Cell Death 1 Ligand 1 (PD-L1) in Acinic Cell Carcinoma (AciCC) of the salivary glands, to enable a correlation with clinico-pathological features and to analyse their prognostic impact. Methods: This single centre retrospective study represents a cohort of 36 primary AciCCs with long-term clinical follow-up. Immunohistochemically defined immune cell subtypes, i.e., those expressing T-cell markers (CD3, CD4 and CD8) or a B-cell marker (CD20) were characterized on tumour tissue sections. The number of TILs was quantitatively evaluated using software for digital bioimage analysis (QuPath). PD-L1 expression on the tumour cells and on immune cells was assessed immunohistochemically employing established scoring criteria: tumour proportion score (TPS), Ventana immune cell score (IC-Score) and combined positive score (CPS). Results: Higher numbers of tumour-infiltrating T- and B- lymphocytes were significantly associated with high-grade transformation. Furthermore, higher counts of T-lymphocytes correlated with node-positive disease. There was a significant correlation between higher levels of PD-L1 expression and lymph node metastases as well as the occurrence of high-grade transformation. Moreover, PD-L1 CPS was associated with poor prognosis regarding metastasis-free survival (p = 0.049). Conclusions: The current study is the first to demonstrate an association between PD-L1 expression and lymph node metastases as well as grading in AciCCs. In conclusion, increased immune cell infiltration of T and B cells as well as higher levels of PD-L1 expression in AciCC in association with high-grade transformation, lymph node metastasis and unfavourable prognosis suggests a relevant interaction between tumour cells and immune cell infiltrates in a subset of AciCCs, and might represent a rationale for immune checkpoint inhibition.

Abstract Background.—Cytokeratin 7 (CK7) and cytokeratin 20 (CK20) are 2 types of intermediate filament protein. Expression of CK7 is seen in the majority of primary urinary bladder carcinomas. CK20 is restricted to superficial and occasional intermediate cells of the normal urothelium of the bladder. Aberrant CK20 expression has been documented in urothelial carcinoma and has proved useful as an ancillary diagnostic aid for urinary bladder tumor. Our hypothesis is that the pattern of CK7 and CK20 expression in metastatic urothelial carcinoma duplicates the expression of the same markers in the primary tumors. Therefore, immunohistochemical staining of metastatic tumors for these 2 markers may be helpful for differential diagnosis in ambiguous metastatic tumor deposits. Objective.—To determine the concordance of CK7 and CK20 expression in primary bladder urothelial carcinoma and the matched lymph node metastasis. Design.—We studied 26 patients with lymph node metastases who underwent radical cystectomy and bilateral lymphadenectomy for bladder carcinoma. Immunohistochemical staining for CK7 and CK20 was performed on formalin-fixed paraffin-embedded tissues containing primary cancers and lymph node metastases. Results.—In all cases, there was a concordant expression of CK20 in the primary cancer and its matched lymph node metastasis. Twelve cases (46%) showed positive CK20 immunoreactivity in the primary tumor and its matched lymph node metastases, whereas 14 cases (54%) were negative for CK20 in both the primary tumor and lymph node metastasis. All cases showed positive CK7 immunoreactivity in the primary cancers and matched lymph node metastases. Conclusions.—CK20 immunoreactivity is reliably observed in metastases from bladder cancer when the primary tumor expresses CK20.

Objective:The purposes of this study were to assess modified radical hysterectomy including systematic pelvic and para-aortic lymphadenectomy followed by adjuvant chemotherapy in patients with para-aortic lymph node (PAN) metastasis in endometrial carcinoma and to identify the multivariate independent prognostic factors for long-term survival during the past 10 years.Methods:Between December 1987 and December 2002, we performed modified radical hysterectomy with bilateral salpingo-oophorectomy including systematic pelvic and para-aortic lymphadenectomy and peritoneal cytology in 284 endometrial carcinoma patients according to the classification of the International Federation of Gynecology and Obstetrics (stage IA, n = 66; stage IB, n = 96; stage IC, n = 33; stage IIA, n = 5; stage IIB, n = 20; stage IIIA, n = 28; stage IIIC, n = 28; and stage IV, n = 8) who gave informed consents at our institute. Patients with tumor confined to the uterus (stages IC and II) were treated by 3 courses of cyclophosphamide 750 mg/m2, epirubicin 50 mg/m2, and cisplatin 75 mg/m2 regimen 3 to 4 weeks apart, and patients with extrauterine lesions involving adnexa and/or pelvic lymph node (PLN) were treated by 5 courses. In addition, 10 courses were given to patients with PAN metastasis. Patients with PLN metastasis received adjuvant chemotherapy, and adjuvant radiation was not part of our institutional protocol. For multivariate regression modeling with proportional hazards, the regression model of Cox was used. Survival curves were analyzed by the Kaplan-Meier method, and analysis of the differences was performed by the log-rank test.Results:The overall incidence of retroperitoneal lymph node metastasis assessed by systematic pelvic and para-aortic lymphadenectomy was 12.0% (34/284) in stages I to IV endometrial carcinoma, and incidences of PLN and PAN metastases were 9.2% (26/284) and 7.4% (21/284), respectively. However, PAN metastasis rate is 50% (13/26) in patients with PLN metastasis. Univariate analysis of prognostic factors revealed that International Federation of Gynecology and Obstetrics clinical stage (P < 0.0001), histological finding (P = 0.0292), myometrial invasion (P < 0.0001), adnexal metastasis (P < 0.0001), lymphovascular space invasion (P < 0.0001), tumor diameter (P = 0.0108), peritoneal cytology (P = 0.0001), and retroperitoneal lymph node metastasis (P < 0.0001) were significantly associated with 10-year overall survival. Survival was not associated with age (P = 0.1558) or cervical involvement (P = 0.1828). A multivariate analysis showed that adnexal metastasis (P = 0.0418) and lymphovascular space invasion (P = 0.0214) were significantly associated with 10-year overall survival. The 5- and 10-year overall survival rates in patients with negative PAN were 96% and 93% versus 72% and 62% in patients with positive PAN (P = 0.006).Conclusions:It is suggested that surgery with systematic pelvic and para-aortic lymphadenectomy followed by adjuvant chemotherapy could improve long-term survival in patients with PAN metastasis, although there are only 21 patients with PAN metastasis.

BackgroundPapillary thyroid cancer (PTC) in clinically lymph node-negative (cN0) patients is prone toward lymph node metastasis. As a risk factor for tumor persistence and local recurrence, lateral lymph node metastasis (LLNM) is related to the number of central lymph node metastases (CLNMs).MethodsWe performed LLNM risk stratification based on the number of CLNMs for cN0 PTC patients who underwent thyroidectomy and lymph node dissection between January 2013 and December 2018. A retrospective analysis was applied to the 274 collected patients with 1-2 CLNMs. We examined the clinicopathological characteristics of the patients and constructed a LASSO model.ResultsIn the 1–2 CLNM group, tumors &gt;10 mm located in the upper region and nodular goiters were independent risk factors for LLNM. Specifically, tumors &gt;20 mm and located in the upper region contributed to metastasis risk at level II. Hashimoto’s thyroiditis reduced this risk (p = 0.045, OR = 0.280). Age ≤ 30 years and calcification (microcalcification within thyroid nodules) correlated with LLNM. The LASSO model divided the population into low- (25.74%) and high-risk (57.25%) groups for LLNM, with an AUC of 0.715.ConclusionsFor patients with 1–2 CLNMs, young age, calcification, nodular goiter, tumor &gt;10 mm, and tumor in the upper region should alert clinicians to considering a higher occult LLNM burden. Close follow-up and therapy adjustment may be warranted for high-risk patients.
