BackgroundFor metachronous second pulmonary squamous cell carcinoma (msPSC) in patients with resected PSC, the method to distinguish tumour clonality has not yet been well established, which makes it difficult to determine accurate staging and predict prognosis.MethodsPatients who underwent surgery for first PSC and encountered msPSC were recruited from the Surveillance, Epidemiology, and End Results (SEER) database. We extracted overall survival 1 (OS1) for the first PSC, overall survival 2 (OS2) for msPSC, and interval survival for the time interval between the first and second PSC. The nomogram was calibrated for OS2, and recursive partitioning analysis (RPA) was performed for risk stratification.ResultsA total of 617 patients were identified. Several independent prognostic factors were identified and integrated into the nomogram for OS2, including gender, age (2nd), nodal status (1st), node metastasis (2nd), and extrapulmonary metastasis (2nd). The calibration curves showed optimal agreement between the predictions and actual observations, and the c-index was 0.678. Surgery was associated with longer survival for msPSC patients. The prognosis of sublobectomy was comparable and inferior to that of lobectomy in the low- and moderate-risk groups, respectively. Radiotherapy was associated with better outcomes in patients who did not undergo surgery.ConclusionsThe RPA-based clinical nomogram appears to be suitable for the prognostic prediction and risk stratification of OS2 in msPSC. This practical system may help clinicians make decisions and design clinical studies. 相似文献

BackgroundDual specificity phosphatase 22 (DUSP22) plays an important role in the regulation of immune and inflammation, but its correlation with clinical features and treatment outcome in psoriasis patients is still unclear. This study was to investigate the longitudinal change of DUSP22 with time, as well as its association with disease activity and treatment response in psoriasis patients.MethodsTotally, 120 psoriasis patients, 50 patients with other skin inflammations as disease controls (DCs), and 50 health controls (HCs) were recruited. Serum samples were collected from psoriasis patients at baseline, month (M)1, M3, and M6 after initiation of etanercept‐based treatment as well as from DCs and HCs after enrollment to assess DUSP22 level by enzyme‐linked immunosorbent assay.ResultsDUSP22 was lower in psoriasis patients than in HCs and DCs (both p < 0.001). Besides, in psoriasis patients, DUSP22 was associated with lower psoriasis area severity index (PASI) score (p = 0.001) and systemic biological treatment history (p = 0.023), but not with other demographics, disease characteristics, or treatment history (all p>0.05). In addition, DUSP22 was increased with time (p < 0.001) in total patients. Moreover, DUSP22 at M3 (p = 0.004) and M6 (p < 0.001) was higher in response patients than in non‐response patients evaluated by PASI 75. Additionally, DUSP22 at M3 (p < 0.001) and M6 (p = 0.003) was also increased in response patients compared with non‐response patients evaluated by PASI 90.ConclusionDUSP22 decreases and negatively correlates with disease activity, while its longitudinal elevation with time reflects satisfactory treatment response in psoriasis patients. 相似文献

Increasing evidence indicates that extracellular vesicles (EVs) play an important role in cancer cell‐to‐cell communication. The Epstein‐Barr virus (EBV)‐encoded latent membrane protein 1 (LMP1), which is closely associated with nasopharyngeal carcinoma (NPC) pathogenesis, can trigger multiple cell signaling pathways that affect cell progression. Several reports have shown that LMP1 promotes EV secretion, and LMP1 trafficking by EVs can enhances cancer progression and metastasis. However, the molecular mechanism by which LMP1 promotes EV secretion is not well understood. In the present study, we found that LMP1 promotes EV secretion by upregulated syndecan‐2 (SDC2) and synaptotagmin‐like‐4 (SYTL4) through nuclear factor (NF)‐κB signaling in NPC cells. Further study indicated that SDC2 interacted with syntenin, which promoted the formation of the EVs, and SYTL4 is associated with the release of EVs. Moreover, we found that stimulation of EV secretion by LMP1 can enhance the proliferation and invasion ability of recipient NPC cells and tumor growth in vivo. In summary, we found a new mechanism by which LMP1 upregulates SDC2 and SYTL4 through NF‐κB signaling to promote EV secretion, and further enhance cancer progression of NPC. 相似文献

目的多功能保留颈淋巴结清除术是治疗分化型甲状腺癌(differentiated thyroid cancer,DTC)颈部淋巴结转移的主要方法,较传统的功能性颈清除术更美观性,颈部功能保留更完善。如何更好的完成该手术,降低术后并发症,一直是外科医师探讨的问题。本研究主要探讨分层解剖在DTC多功能保留颈淋巴结清除术中应用的可行性及意义。方法回顾性分析沧州市中心医院2008-05-01—2019-03-31因DTC行甲状腺切除加Ⅱ~Ⅵ区多功能保留颈淋巴结清除术的457例患者临床资料,分为分层解剖法多功能保留手术组(A组,235例)和常规多功能保留手术组(B组,222例)。记录2组的手术学指标、术后并发症和出院时间等。采用χ^2检验及t检验对数据进行分析。结果2组患者基线资料比较,差异均无统计学意义,均P>0.05。A与B组手术时间分别为(127.85±14.65)和(136.80±14.65)min,t=-6.529,P<0.001;出血量分别为(34.38±14.44)和(48.02±18.88)mL,t=-8.705,P<0.001;术后住院时间分别为(8.57±1.41)和(11.59±2.21)d,t=-17.469,P<0.001;差异均有统计学意义。术后并发症发生率A组比B组更少,声音嘶哑发生率分别为1.28%(3/235)和4.50%(10/222),χ^2=4.304,P=0.038;皮缘坏死发生率分别为0.43%(1/235)和4.05%(9/222),χ^2=7.022,P=0.008;低血钙发生率分别为5.11%(12/235)和13.51%(30/222),χ^2=9.668,P=0.002;差异均有统计学意义。结论分层解剖法多功能保留手术不破坏解剖层次界限,明显缩短手术时间,减少术中出血,降低术后并发症发生率。因此其在甲状腺癌多功能保留的颈淋巴结清除术中合理可行。 相似文献

Therapeutics targeting osteoclasts are commonly used treatments for bone metastasis; however, whether and how osteoclasts regulate premetastatic niche and bone tropism are largely unknown. In this study, we report that osteoclast precursors (OPs) can function as a premetastatic niche component that facilitates breast cancer (BCa) bone metastasis at early stages. At the molecular level, unbiased GPCR ligand/agonist screening in BCa cells suggested that R-spondin 2 (RSPO2) and RANKL, through interaction with their receptor LGR4, promoted osteoclastic premetastatic niche formation and enhanced BCa bone metastasis. This was achieved by RSPO2/RANKL-LGR4 signal modulating the WNT inhibitor DKK1 through Gαq and β-catenin signaling. DKK1 directly facilitated OP recruitment through suppression of its receptor LDL receptor–related protein 5 (LRP5) but not LRP6, upregulating Rnasek expression via inhibition of canonical WNT signaling. In clinical samples, RSPO2, LGR4, and DKK1 expression showed a positive correlation with BCa bone metastasis. Furthermore, soluble LGR4 extracellular domain (ECD) protein, acting as a decoy receptor for RSPO2 and RANKL, significantly alleviated bone metastasis and osteolytic lesions in a mouse bone metastasis model. These findings provide unique insights into the functional role of OPs as key components of the premetastatic niche for BCa bone metastasis and identify RSPO2/RANKL-LGR4 signaling as a promising target for inhibiting BCa bone metastasis. 相似文献

Rationale:Omental liposarcoma is extremely rare, and only a few reports have been published in the literature. Due to the rarity of the disease, establishing a clear diagnosis and formulating a treatment plan may be challenging for clinicians.Patient concerns:The patient was a 51-year-old woman who presented with a protruding mass and pain in the lower abdomen.Diagnosis:Magnetic resonance imaging revealed a tumor measuring 15 cm in diameter in the pelvis. Ovarian cancer was suspected based on pre-operative imaging findings.Interventions:An exploratory laparotomy was performed. Intra-operative analysis of the frozen section suggested a benign tumor.Outcomes:Postoperative histopathological analysis confirmed the diagnosis of omental liposarcoma. The patient recovered well after surgery.Lesson:This case report helps clinical oncologists to develop a comprehensive understanding of this disease and treat it accordingly. 相似文献
