Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (ICC) is a highly malignant neoplasm and characterized by desmoplastic matrix. The heterogeneity and crosstalk of tumor microenvironment remain incompletely understood. METHODS To address this gap, we performed Weighted Gene Co-expression Network Analysis (WGCNA) to identify and construct a cancer associated fibroblasts (CAFs) infiltration biomarker. We also depicted the intercellular communication network and important receptor-ligand complexes using the single-cell transcriptomics analysis of tumor and Adjacent normal tissue. RESULTS Through the intersection of TCGA DEGs and WGCNA module genes, 784 differential genes related to CAFs infiltration were obtained. After a series of regression analyses, the CAFs score was generated by integrating the expressions of EVA1A, APBA2, LRRTM4, GOLGA8M, BPIFB2, and their corresponding coefficients. In the TCGA-CHOL, GSE89748, and 107,943 cohorts, the high CAFs score group showed unfavorable survival prognosis (p < 0.001, p = 0.0074, p = 0.028, respectively). Additionally, a series of drugs have been predicted to be more sensitive to the high-risk group (p < 0.05). Subsequent to dimension reduction and clustering, thirteen clusters were identified to construct the single-cell atlas. Cell-cell interaction analysis unveiled significant enhancement of signal transduction in tumor tissues, particularly from fibroblasts to malignant cells via diverse pathways. Moreover, SCENIC analysis indicated that HOXA5, WT1, and LHX2 are fibroblast specific motifs. CONCLUSIONS This study reveals the key role of fibroblasts - oncocytes interaction in the remodeling of the immunosuppressive microenvironment in intrahepatic cholangiocarcinoma. Subsequently, it may trigger cascade activation of downstream signaling pathways such as PI3K-AKT and Notch in tumor, thus initiating tumorigenesis. Targeted drugs aimed at disrupting fibroblasts-tumor cell interaction, along with associated enrichment pathways, show potential in mitigating the immunosuppressive microenvironment that facilitates tumor progression.

Abstract
BACKGROUND Minimally invasive surgery for intrahepatic cholangiocarcinoma (ICC) remains challenging, especially in advanced patients. PATIENT AND METHOD A 66-year-old male was diagnosed with stage II ICC after a comprehensive evaluation and was scheduled for laparoscopic exploration and left hepatectomy. RESULTS The pure laparoscopic left hepatectomy was completed in 240 min, employing a no-touch en bloc technique and lymphadenectomy skeletonization. The patient was discharged 6 days after the operation without any complications and received gemcitabine and cisplatin treatment postoperatively. There was no recurrence during 14 months of follow-up. CONCLUSIONS Our experience demonstrates that when utilizing the no-touch en bloc technique, standardized lymphadenectomy through skeletonization, and effective control of bleeding, surgeons with extensive expertise in laparoscopic hepatectomy can achieve results comparable to open surgery.

Abstract
The platelet to lymphocyte ratio (PLR) is the marker of host inflammation and it is a potential significant prognostic indicator in various different tumors. The serum carbohydrate antigen 19-9 (CA19-9) is a tumor-associated antigen and it is associated with poor prognosis of gallbladder cancer (GBC). We aimed to analyze the prognostic value of the combination of preoperative PLR and CA19-9 in patients with GBC. A total of 287 GBC patients who underwent curative surgery in our institution was included. To analyze the relationship between PLR and CA19-9 and clinicopathological features. A receiver operating characteristic (ROC) curve was used to identify the optimal cutoff value for PLR and CA19-9. The Kaplan-Meier method was used to estimate the overall survival (OS). Meanwhile, the univariate and multivariate Cox regression models were used to assess the risk factors for OS. The cutoff values of 146.82 and 36.32U/ml defined as high PLR and high CA19-9, respectively. Furthermore, survival analysis showed that patients with PLR > 146.82 and CA19-9 > 36.32 U/ml had a worse prognosis than patients with PLR ≤ 146.82 and CA19-9 ≤ 36.32 U/ml, respectively. The multivariate analysis demonstrated that PLR (hazard ratio (HR) = 1.863, 95% CI: 1.366-2.542, P < 0.001) and CA19-9 (HR = 1.412, 95% CI: 1.021-1.952, P = 0.037) were independent prognostic factors in the GBC patients. When we combined these two parameters, the area under the ROC curve increased from 0.624 (PLR) and 0.661 (CA19-9) to 0.711. In addition, the 1-, 3-, and 5-year OS of group A (patients with PLR ≤ 146.82 and CA19-9 ≤ 36.32 U/ml), group B (patients with either of PLR > 146.82 or CA19-9 > 36.32 U/ml) and group C (patients with PLR > 146.82 and CA19-9 > 36.32 U/ml) were 83.6%, 58.6%, 22.5%, 52.4%, 19.5%, 11.5%, and 42.3%, 11.9%, 0%, respectively. The preoperative PLR and serum CA19-9 are associated with prognosis of patients with GBC. The combination of PLR and CA19-9 may serve as a significant prognostic biomarker for GBC patients superior to either PLR or CA19-9 alone.

Abstract
BACKGROUND The neutrophil-lymphocyte ratio (NLR) and platelet distribution width (PDW) are associated with poor prognosis in various cancers. We aimed to analyze the prognostic value of the combination of preoperative NLR and PDW in patients with gallbladder carcinoma (GBC). METHODS A total of 287 GBC patients who underwent curative-intent surgery in our institution was included. The relationship between NLR and PDW and clinicopathological features were analyzed. The receiver operating characteristic (ROC) curves were used to determine the optimal cutoff value for NLR and PDW. Overall survival (OS) was estimated using the Kaplan-Meier method. Meanwhile, the univariate and multivariate Cox regression models were used to assess the risk factors for OS. RESULTS The optimal cutoff value of NLR and PDW was 3.00 and 14.76, respectively. In addition, survival analysis demonstrated that patients with NLR > 3.00 and PDW > 14.76 had a worse prognosis than patients with NLR ≤ 3.00 and PDW ≤ 14.76, respectively. The multivariate analysis showed that NLR and PDW were independent prognostic factors in the patients with GBC. When we combined NLR and PDW, the area under the ROC curve increased from 0.665 (NLR) and 0.632 (PDW) to 0.676. Moreover, the 1-, 3-, and 5-year OS of group A (patients with NLR ≤ 3.00 and PDW ≤ 14.76), group B (patients with either of NLR > 3.00 or PDW > 14.76) and group C (patients with NLR > 3.00 and PDW > 14.76) were 88.7%, 62.6%, 28.1%, 65.1%, 26.9%, 13.1%, and 34.8%, 8.3%, 0%, respectively. CONCLUSION The combination of NLR and PDW may serve as a significant prognostic biomarker for GBC patients superior to either NLR or PDW alone.

Abstract
BACKGROUND Tumor necrosis has been indicated to correlate with dismal survival outcomes of a variety of solid tumors. However, the significance and prognostic value of tumor necrosis remain unclear in gallbladder carcinoma. The aim of this research is to explore the relationships between necrosis with long-term survival and tumor-related biological characteristics of patients with gallbladder carcinoma. PATIENTS AND METHODS Patients with gallbladder carcinoma who accepted curative-intent resection in West China Hospital of Sichuan University (China) between January 2010 and December 2021 were retrospectively analyzed. Tumor necrosis was determined by staining the patient's original tissue sections with hematoxylin and eosin. Based on the presence of tumor necrosis, the pathologic features and survival outcomes were compared. RESULTS This study enrolled 213 patients with gallbladder carcinoma who underwent curative-intent surgery, of whom 89 had tumor necrosis. Comparative analyses indicated that patients with tumor necrosis had more aggressive clinicopathological features, such as larger tumor size (p = 0.002), poorer tumor differentiation (p = 0.029), more frequent vascular invasion (p < 0.001), presence of lymph node metastasis (p = 0.014), and higher tumor status (p = 0.01), and experienced poorer survival. Univariate and multivariate analyses revealed that tumor necrosis was an independent prognostic factor for overall survival (multivariate: HR 1.651, p = 0.026) and disease-free survival (multivariate: HR 1.589, p = 0.040). CONCLUSIONS Tumor necrosis can be considered as an independent predictive factor for overall survival and disease-free survival among individuals with gallbladder carcinoma, which was a valuable pathologic parameter.

Abstract
Pancreatic cancer is a malignant disease with a dismal prognosis. While neoadjuvant therapy has shown promise in the treatment of pancreatic cancer, its role remains a subject of controversy among physicians. We aimed to evaluate the benefits of neoadjuvant therapy in patients with resectable and borderline resectable pancreatic cancer. Eligible studies were identified from MEDLINE, Embase, Cochrane Library, and Web of Science. Studies comparing neoadjuvant therapy with upfront surgery (with or without adjuvant therapy) in resectable and borderline resectable pancreatic cancer were included. The primary endpoint assessed was overall survival. A total of 10,022 studies were identified, and the meta-analysis finally enrolled 50 revealed studies. The meta-analysis suggested that neoadjuvant therapy significantly improved the overall survival (HR 0.74, p < 0.001) and recurrence-free survival (HR 0.75, p = 0.006) compared to the upfront surgery approach. Furthermore, neoadjuvant therapy leads to favorable postoperative outcomes, with an enhanced R0 resection rate (OR 1.90, p < 0.001) and reduced lymph node metastasis (OR 0.36, p < 0.001) and perineural invasion (OR 0.42, p < 0.001), although it is associated with a reduced resection rate (OR 0.42, p < 0.001). In addition, patients treated with neoadjuvant therapy experience superior survival benefits compared to those undergoing adjuvant therapy (HR 0.87, p = 0.019). These results are further corroborated by the subgroup analysis of randomized controlled trials. Neoadjuvant therapy has the potential to provide survival benefits and improve postoperative long-term outcomes for patients with resectable and borderline resectable pancreatic cancer. However, to validate and reinforce these findings, further well-designed and large trials are required.

Abstract
The significance of peri-neural invasion (PNI) in patients with gallbladder carcinoma (GBC) after curative surgery remains unknown. Current study was performed to evaluate the significance of PNI in resected GBC patients in terms of tumor-related biological features and long-term survival. Patients with GBC between September 2010 and September 2020 were reviewed and analyzed. SPSS 25.0 software were used for statistical analysis. A total of 324 resected GBC patients were identified (No. PNI: 64). An elevated preoperative Ca19.9 level (P = 0.001), obstructive jaundice (P = 0.001), liver invasion (P < 0.0001), lymph-vascular invasion (P < 0.0001), lymph-node metastasis (P < 0.0001), and poor or moderate differentiation status (P = 0.036) were more frequently detected in patients with PNI. Major hepatectomy (P = 0.019), bile duct resection (P < 0.0001), combined multi-visceral resections (P = 0.001), and combined major vascular resections and reconstructions (P = 0.002) were also more frequently detected. However, a significantly lower R0 rate (P < 0.0001) was acquired in patients with PNI. Patients with PNI were generally more advanced disease and shared a much worse prognosis even after matching. PNI was an independent prognostic factor of disease-free survival as well as an independent predictor of early recurrence. Postoperative adjuvant chemotherapy has brought an obvious survival benefit in resected GBC patients with PNI. PNI could be regarded as an indicator of worse prognosis and could serve as an independent predictor of early recurrence. Postoperative adjuvant chemotherapy was correlated with an improved survival for resected GBC patients with PNI. Upcoming multicenter studies covering various races are warranted for further validation.

Abstract
OBJECTIVE To evaluate the significance of tumor locations in patients with resected gallbladder carcinoma (GBC) and to supply the indication of extra-hepatic bile duct resection (EHBDR) according to tumor locations. METHODS Patients with resected GBC from 2010 to 2020 in our hospital were retrospectively analyzed. Comparative analyses and a meta-analysis were performed according to different tumor locations (body/fundus/neck/cystic duct). RESULTS Article: A total of 259 patients were identified (neck: 71; cystic: 29; body: 51; fundus: 108). Patients with proximal tumors (neck/cystic duct) were often in a more advanced stage and had more aggressive tumor biological features as well as a worse prognosis compared with those with distal tumors (fundus/body). Moreover, the observation was even more obvious between cystic duct and non-cystic duct tumors. Cystic duct tumor was an independent prognostic factor for overall survival (P = 0.01). EHBDR provided no survival advantage even in those with cystic duct tumor. META-ANALYSIS With our own cohort incorporated, five studies with 204 patients with proximal tumors and 5167 patients with distal tumors were identified. Pooled results revealed that proximal tumors indicated worse tumor biological features and prognosis versus distal tumors. CONCLUSION Proximal GBC had more aggressive tumor biological features, and a worse prognosis versus distal GBC and cystic duct tumor can be regarded as an independent prognostic factor. EHBDR had no obvious survival advantage even in those with cystic duct tumor and was even harmful in those with distal tumors. Upcoming more powerful well-designed studies are required for further validation.
