Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

Background: s/Aims: Distal pancreatectomy with splenectomy (DPS) is a common surgical procedure for pancreatic body cancer.However, spleen-preserving distal pancreatectomy (SPDP) utilizing the Warshaw technique (WT) in malignancies is generally not favored due to concerns about inadequate resection. This study aims to assess the feasibility and oncologic outcomes of employing SPDP with WT in pancreatic body cancer. Methods: We conducted a retrospective analysis comparing 21 SPDP patients with 63 DPS patients matched by propensity score from January 2018 to November 2022. Clinical outcomes and follow-up data were analyzed using R. Results: Both groups exhibited similar demographic, intraoperative, and pathological characteristics, with the exception of a reduced number of total lymph nodes (p = 0.006) in the SPDP group. There were no significant differences in the rates of postoperative complications, recurrence, or metastasis. Local recurrence predominantly occurred in the central region as opposed to the spleen region.There were no cases of isolated recurrences in the splenic region. Median overall survival and recurrence-free survival times were 51.5 months for SPDP vs 30.5 months for DPS and 18.7 months vs 16.8 months, respectively (p > 0.05). The incidence of partial splenic infarction and left-side portal hypertension in the SPDP group was 28.6% (6/21) and 9.5% (2/21), respectively, without necessitating splenic abscess puncture, splenectomy, or causing bleeding from perigastric varices. Conclusions SPDP did not negatively impact local recurrence or survival rates in selected pancreatic body cancer patients. Further studies are necessary for validation.

Tumor microenvironment is the result of dynamic interactions between different cellular and non-cellular components,including cancer cells themselves,extracellular matrix,immune cells and various non immune cells.Microenvironment is closely related to the growth,metastasis and prognosis of breast cancer,and is closely related to the current popular targeted therapy and immunotherapy.Radiomics is a new field of translational medicine based on extracting high-dimensional data from images to obtain reliable models that can be applied to clinical practice.In this review,the latest advances in the application of radiomics to the tumor microenvironment of breast cancer are discussed.

Objective:To explore the effects of Levothyroxine Sodium (L-T4) treatment on coagulation function and adverse pregnancy outcomes in patients with hypothyroidism during pregnancy in early and mid-to-late pregnancy.Methods:A total of 120 patients with hypothyroidism during pregnancy who were treated by L-T4 in Linyi Central Hospital from Mar. 2021 to Mar. 2024 were included, and their clinical data were retrospectively analyzed. According to the gestational age of the patients at the time of treatment, 64 cases with a gestational age of <12 weeks were included in the early pregnancy group, and 56 cases with a gestational age of ≥12 weeks were included in the mid-to-late pregnancy group. The serum thyroid hormone indexes, coagulation function indexes, adverse pregnancy outcomes, and neuropsychological development of the offspring were compared between the two groups. Statistical analyses were conducted using independent/paired t-tests and chi-square tests.Results:After treatment, there were no significant differences in the thyroid hormone indexes and coagulation function indexes between the early pregnancy group and the middle and late pregnancy group ( P>0.05). The incidence of fetal growth restriction and gestational hypertension in the early pregnancy group was 10.94% (7/64) and 17.19% (11/64), and that in the middle and late pregnancy group was 26.79% (15/56) and 33.93% (19/56), respectively. The incidence in the early pregnancy group was significantly lower than that in the middle and late pregnancy group ( χ2=5.010, 4.464, P<0.05). The developmental quotient (DQ) of the offspring in the early pregnancy group at 6 months of age in various areas of neuropsychological development (social behavior, language, adaptability, fine motor skills and gross motor skills) was significantly higher than that in the middle and late pregnancy group. The DQ of the first trimester group was (97.82±7.25) points, (94.59±6.85) points, (95.87±8.02) points, (96.08±7.25) points, and (98.34±8.07) points. The DQ of the second trimester group was (92.54±7.06) points, (90.45±6.14) points, (91.01±7.51) points, (91.24±7.08) points, and (92.74±7.38) points. The DQ of the first trimester group was significantly higher than that of the second trimester group ( t=4.029, 3.466, 3.411, 3.688, 3.946, P<0.05) . Conclusion:L-T4 treatment in early or mid- to late-pregnancy patients with gestational hypothyroidism can effectively improve their thyroid hormone levels and coagulation function, but treatment in early pregnancy is beneficial to reduce the incidence of adverse pregnancy outcomes such as fetal growth restriction and alleviate the impact of the disease on the neuropsychological development of offspring.
