Abstract Background: Solid pseudopapillary neoplasm (SPN) is an uncommon pathology with a low-grade malignancy. Surgery is the milestone treatment. Nevertheless, despite appropriate management, some patients present recurrence. Risk factors associated with recurrence are unclear. The objective of this study was to identify the clinicopathological factors associated with recurrence in patients with the diagnosis of SPN treated with pancreatic resection.Methods: In this retrospective single-center study, medical records of patients treated with pancreatic resection from January 2006 to January 2020 were evaluated. Patients with histological diagnosis of SPN were included. Survival analysis was performed to identify the clinicopathological factors related to recurrence.Results: A total of 589 patients underwent pancreatectomy and, 74(12.6%) were diagnosed with SPN. Seventy patients (94.6%) were female and 4 were male. The median age was 20 years old and, 49(67%) patients were <28 years. The principal symptom was abdominal pain (n=62)(83.8%). The pancreatic head was the most frequent tumor localization (n=32)(43.2%). Distal pancreatectomy was performed in 33(44.6%) patients, followed by pancreaticoduodenectomy (n=32)(43.2%). The median tumor diameter was 7.9cm and, 24(32%) patients presented tumors ≥ 10 cm. Multivisceral resection was performed in 9(12.2%) patients. Four(5.4%) patients presented lymph node metastasis. R0 resection was achieved in all cases. The overall 90-days postoperative morbidity and mortality were 54% and 1.4%, respectively. The pancreatic fistula was the principal postoperative complication(n=27;36.5%). Six(8%) patients presented recurrence after pancreas resection. Liver metastasis was the most frequent recurrence site(n=5). After a median follow-up of 40.2 months, 9(12%) patients died. Five(6.8%) patients died of disease progression. The 1-3-and-5-year OS was 97.1%,90.2% and 79.9%, respectively. The 1-3-and-5-year RFS was 98.4%,89.9% and 87%, respectively. In the univariate Cox regression analysis, age ≥28 years (HR=8.61,95%CI:1.1–73.8), tumor diameter ≥10cm (HR=9.3,95%CI:1.12-79.6), invasion of adjacent organs (HR=7.45,95%CI:1.5–36.9), lymph node metastasis (pN+) (HR=16.8,95%CI:2.96–94.9) and, AJCC(TNM) Stage III (HR=10.1,95%CI:1.2–90.9) were identified as predictors for recurrence. Conclusions: SPN is more frequently diagnosed in young women with a good overall prognosis after an R0 surgical resection even with disease recurrence. Age ≥28 years, larger tumors ≥10cm, invasion of adjacent organs, lymph node metastasis(N+) and, AJCC Stage III were predictors factors of recurrence in resected SPN.

Background and Aims. Various risk factors for lymph node metastasis (LNM) have been reported in colorectal T1 cancers. However, the factors available are insufficient for predicting LNM. We therefore investigated the utility of the new histological factor “pure well-differentiated adenocarcinoma” (PWDA) as a safe factor for predicting LNM in T1 and T2 cancers. Materials and Methods. We reviewed 115 T2 cancers and 202 T1 cancers in patients who underwent surgical resection in our center. We investigated the rates of LNM among various clinicopathological factors, including PWDA. PWDA was defined as a lesion comprising only well-differentiated adenocarcinoma. The consistency of the diagnosis of PWDA was evaluated among two pathologists. In addition, 72 T1 cancers with LNM from 8 related hospitals over 10 years (2008–2017) were also analyzed. Results. The rates of LNM and PWDA were 23.5% and 20.0%, respectively, in T2 cancers. Significant differences were noted between patients with and without LNM regarding lymphatic invasion (81.5% vs. 36.4%, p<0.001), poor histology (51.9% vs. 19.3%, p=0.008), and PWDA (3.7% vs. 25.0%, p=0.015). The rates of LNM and PWDA were 8.4% and 36.1%, respectively, in T1 cancers. Regarding the 73 PWDA cases and 129 non-PWDA cases, the rates of LNM were 0.0% and 13.2%, respectively (p<0.001). Among the 97 cases with lymphatic or venous invasion, the rates of LNM in 29 PWDA cases and 68 non-PWDA were 0% and 14.7%, respectively (p=0.029). The agreement of the two pathologists for the diagnosis of PWDA was acceptable (kappa value > 0.5). A multicenter review showed no cases of PWDA among 72 T1 cancers with LNM. Conclusions. PWDA is considered to be a safe factor for LNM in T1 cancer.

Pulmonary sclerosing pneumocytoma (PSP) is a rare benign or low-grade malignant tumor, but it has the potential to present with multiple lesions, lymph node metastasis, extra-pulmonary metastasis, recurrence and even cause death. Herein, a case of PSP that was huge, presented with multiple lesions and had lymph node as well as extrapulmonary metastases (liver, abdominal cavity, bones) is reported for the first time. This patient was also the first one to die of respiratory and circulatory failure caused by the PSP tumor and its metastases which compressed the mediastinal tissue.

Tumor deposits in colon cancer are related to poor prognosis, whereas the prognostic power of tumor deposits in combination with lymph node metastasis (LNM) is controversial. This study aimed to compare the overall survival between LNM alone and LNM in combination with tumor deposits, and to verify whether the number of tumor deposits can be considered LNM in patients with both LNM and tumor deposits in stage III colon cancer by propensity score matching (PSM). Patients carrying resected stage III adenocarcinoma of colon cancer were identified from the Surveillance, Epidemiology, and End Results database (2010–2015). The Kaplan-Meier method, Cox proportional hazard models and PSM were used. On the whole, 23,168 patients (20,451 (88.3%) with only LNM and 2,717 (11.7%) with both LNM and tumor deposits) were selected. After undergoing PSM, patients with both LNM and tumor deposits showed worse overall survival (hazard ratio = 1.33, 95% confidence interval: 1.20–1.47, P < 0.001). After the number of tumor deposits was added with that of positive regional lymph nodes, patients with both LNM and tumor deposits seemed to have prognostic implications similar to those with LNM alone (hazard ratio = 1.02, 95% confidence interval: 0.93–1.12, P = 0.66). The simultaneous presence of LNM and tumor deposits, as compared with the presence of only LNM, had an association with a worse outcome. Tumor deposits should be considered as LNM in patients with both tumor deposits and LNM in stage III colon cancer.

Abstract Background The aim of this study is to determine pathological factors that increase the risk of LNM and indicate poor survival of patients diagnosed with endometrial cancer and treated with surgical staging. Method Between January 2010 and November 2018, we enrolled 874 eligible patients who received staging surgery in the First Affiliated Hospital of Anhui Medical University. The roles of prognostic risk factors, such as age, histological subtype, tumor grade, myometrial infiltration, tumor diameter, cervical infiltration, lymphopoiesis space invasion (LVSI), CA125, and ascites, were evaluated. Multivariable logistic regression models were used to identify the predictors of LNM. Kaplan–Meier and COX regression models were utilized to study the overall survival. Results Multivariable regression analysis confirmed cervical stromal invasion (OR 3.412, 95% CI 1.631–7.141; P < 0.01), LVSI (OR 2.542, 95% CI 1.061–6.004; P = 0.04) and ovarian metastasis (OR 6.236, 95% CI 1.561–24.904; P = 0.01) as significant predictors of nodal dissemination. Furthermore, pathological pattern (P = 0.03), myometrial invasion (OR 2.70, 95% CI 1.139–6.40; P = 0.01), and lymph node metastasis (OR 9.675, 95% CI 3.708–25.245; P < 0.01) were independent predictors of decreased overall survival. Conclusions Cervical invasion, lymphopoiesis space invasion, and ovarian metastasis significantly convey the risk of LNM. Pathological type, myometrial invasion, and lymph node metastasis are all important predictors of survival and should be scheduled for completion when possible in the surgical staging procedure.
