Immune checkpoint inhibitors (ICIs) such as anti-programmed death-1 (PD-1) and its ligand PD-L1 and anti-cytotoxic T-lymphocyte antigen 4 (CTLA-4) monoclonal antibodies, are involved in T cell-mediated immune response augmentation and promote anti-tumor immunity. Cancer patients treated with combination of immunotherapy, chemotherapy, radiotherapy, and targeted therapy exhibit superior clinical outcomes and tolerance compared with patients treated with monotherapies. However, immutherapy is associated with several concomitant immune-related adverse events (irAEs). For instance, IrAEs interferes with function of gastrointestinal tract, endocrine, dermatological, nervous system and musculoskeletal systems. ICIs-associated pancreatic injury might causes decrease in endocrine and exocrine pancreatic function, resulting in metabolic and nutritional disorders. Clinicians who administer immune checkpoint inhibitors to cancer patients are diagnosed with hyperglycemia, abdominal pain and steatorrhea. Currently, the precise mechanism of ICIs-associated pancreatic injury has not been fully explored. This paper summarizes incidence, diagnosis, clinical characteristics, potential mechanisms, and treatment management patterns of ICIs-associated pancreatic AEs based on previous studies. In addition, possible management approaches of these adverse effects are presented in this paper. in the findings summarized in this paper lay a basis for management of ICIs-associated pancreatic AEs and expanding future immunotherapy applications.
A 27-year-old female with chronic right-side flank pain was diagnosed with renal epithelioid angiomyolipoma (EAML) extending as a thrombus into the renal vein and vena cava. Intravascular extension of EAML is quite rare; however, it may result in fatal complications if not appropriately treated. She successfully underwent a radical nephrectomy and inferior vena caval thrombectomy. Intravascular extension of EAML, although rare, has been reported. We present a new case and a description of the surgical management. Furthermore, we reviewed and analyzed nine case reports of invasive renal EAMLs.
Although pancreatic neuroendocrine tumors (PNETs) are generally considered to have a favorable overall prognosis after resection, disease recurrence has been observed. Few studies have specifically addressed recurrence after resection of PNETs, especially for non-functioning PNETs (NF-PNETs). The aim of our study is to analyze the recurrence of resected well-differentiated NF-PNETs. Patients who underwent surgical resection for grade 1 and 2 NF-PNETs without synchronous metastasis were identified for analysis. Patients were treated from January 2009 to December 2017 in our institution. Univariate and multivariate cox regression analysis were conducted to identify prognostic factors. Of the 88 patients, 46 were men (52%) and the mean age was 52 years. With a median follow-up of 49.1 months (range, 8–122 months), there were 12 recurrences (14%). Liver was the most common recurrence site (7/12, 58%). The 1-, 3-, and 5-year recurrence-free survival was 99%, 90%, and 88%, respectively. Univariate analysis identified that age >52 years, positive lymph nodes, tumor grade 2, and Ki67 index ≥5% were statistically significant. Multivariate analysis identified that Ki67 index ≥5% (hazard ratio [HR], 4.69; 95% confidence interval [CI], 1.36–16.75, P = .015), positive lymph nodes (HR, 6.75; 95% CI, 1.73–24.43, P = .006) were independently associated with recurrence. The 5-year disease-free survival rate was 53% (95% CI, 14.20–91.81%) for patients with Ki-67 ≥5% or (and) positive lymph nodes, while 95% (95% CI, 82.26–100%) for the patients without these 2 factors. Ki67 index and lymph node status are independently associated with recurrence after resection of well-differentiated NF-PNETs in this study.
Background: Owing to the limited prevalence and heterogeneity, it is difficult to predict long-term survival of non-functional pancreatic neuroendocrine tumours (NF-PNETs).This study aimed to evaluate the factors predicting disease-specific survival (DSS) for welldifferentiated NF-PNETs. Methods: Data were collected retrospectively from 256 patients with pancreatic neuroendocrine tumours who underwent surgical resection between January 2009 and December at our institution. Of these, 103 NF-PNETs (40%) were identified for analysis. Results: Of the 103 patients, 54 were male (52%) and the mean age was 52 years (range 21-75 years). Most patients (60/103, 58%) in our series were symptomatic. Seventeen patients (16%) died during follow-up, with a median period of 47 months. There were 88 patients with well-differentiated tumours and 10 of them (10/88, 11%) died of tumour progression. Median DSS after primary resection was 58.8 months (range 16-122 months). Multivariate analysis identified age >52 years (P = 0.038) and tumour grade G2 (P = 0.001) as statistically significant predictors of DSS. There was no association between gender, tumour size, symptoms, surgical procedure, severe complications, tumour location, tumour size, resection margin, positive lymph nodes and vascular invasion with DSS. Conclusion: Tumour grade, age, presence of symptoms and distant metastasis were related to poor DSS of NF-PNETs. Age >52 years and tumour grade G2 might be independent predictors of poor DSS for patients with well-differentiated NF-PNETs.
Objective This systematic review aims to examine the influencing factors of undergraduates’ depressive symptoms by summarizing the categories and intensity of the factors, to lay a foundation for subsequent research. Methods Two authors independently searched in Medline (Ovid), Embase (Ovid), Scopu, PsycINFO, PsycARTICLES, the Chinese Scientific Journal Database (VIP Database), China National Knowledge database (CNKI), and the WanFang database for cohort studies related to the influencing factors affecting depressive symptoms among undergraduates published prior to September 12, 2022. Adjusted Newcastle-Ottawa scale (NOS) was used to assess the risk of bias. Meta-analyses of regression coefficient estimates were performed to calculate pooled estimates with R 4.0.3 software. Results A total of 73 cohort studies were included, involving 46362 participants from 11 countries. Factors affecting depressive symptoms were classified into relational, psychological, predictors of response to trauma, occupational, sociodemographic and lifestyle factors. In Meta-analysis, 4 of 7 influencing factors were revealed to be statistically significant: negative coping (B = 0.98, 95%CI: 0.22–1.74), rumination (B = 0.06, 95%CI: 0.01–0.11), stress (OR = 0.22, 95%CI: 0.16–0.28) and childhood abuse (B = 0.42, 95%CI:0.13–0.71). No significant association was found in positive coping, gender and ethnicity. Limitations The current studies have the problems of inconsistent use of scales and large heterogeneity of research design, making it difficult to summarize, which is expected to be further improved in future research. Conclusion This review evidences the importance of several influencing factors of depressive symptoms among undergraduates. We advocate for more high-quality studies with more coherent and appropriate study designs and outcome measurement approaches in this field.
