Mean Survival Time Of Patients Research Articles

SMARCA4-deficient undifferentiated tumor with high quality of life and far exceeding predicted survival: A case report.

SMARCA4-deficient undifferentiated tumor (SMARCA4-UT) is a recently reported rare malignancy that can rapidly metastasize to tissues and organs throughout the body. The tumor is characterized by a lower response to platinum-based chemotherapy. More regrettably, the mean survival time of patients with this disease after diagnosis is only 4 to 7 months. A 58-year-old man was admitted to a hospital for fatigue, sudden syncope, and a mass-like shadow of his left upper lobe demonstrated by a pulmonary computed tomographic. Based on his subsequent clinical and pathological features, he was highly suspected of SMARCA4-UT. Combined with next-generation sequencing genetic testing and immunohistochemical examination results, the patient was diagnosed with SMARCA4-UT. The patient received a left upper lobectomy and lymph node dissection, four-course chemotherapy divided into 8 sessions with the use of paclitaxel simply, and a proper post-discharge self-care. The patient's operation and chemotherapy were all successful and he maintained a high quality of life after surgery that far exceeded his predicted survival. Early diagnosis, higher education level, attention to the disease and complications, reducing chemotherapy damage, adequate nutrient intake, relieving symptoms, controlling depression, and maintaining immunity and the ability to perform activities of daily living may all be the positive factors that can prolong the survival of patients with SMARCA4-UT.

ATRT-20. ATYPICAL TERATOID RHABDOID TUMOR: ASSOCIATION OF CLINICAL, HISTOLOGICAL, RADIOLOGICAL, MOLECULAR, AND THERAPEUTIC DATA WITH THE SURVIVAL OF PATIENTS ATTENDED AT IOP/GRAACC/UNIFESP

Abstract BACKGROUND In childhood, Atypical Rhabdoid Teratoid Tumor accounts for 2% of cases of brain tumors. There is no consensus for the treatment, resulting in multiple protocols. METHODS Retrospective study at the Institute of Pediatric Oncology-IOP/GRAACC/UNIFESP, from January 2000 to December 2022. There were 31 patients admitted during this period. The classification of the histological type into rhabdoid/classic, small round and blue cells, epithelial, and mesenchymal was carried out by the same pathologist, and a 50% cutoff characterized the predominant pattern. A neuro-radiologist reviewed the radiological data. Molecular analysis was performed using NGS. RESULTS In patients <3yo, 74.9% of patients died. Overall survival (OS) at 3 years was 24.5%, and progression-free survival (PFS) at 3 years was 13.8%. In patients <3yo, the absence of metastases was associated with a higher OS and PFS (3y-OS 35.6% and 3y-PFS 23.7%, vs 3y-OS 10% and 3y-PFS 0% in patients with M+). The OS was higher in patients who received radiotherapy at the first treatment (3y-OS of 66.6% vs 7.8% in the non-irradiated group). The classic histological pattern had a lower PFS than the epithelial and small cell groups (p=0.021). In patients>3 yo, 57.1% of patients died. The 3y-OS was 38.1% and the 3y-PFS was 53.5%. In this age group, there was no difference in OS and PFS considering metastases, location, histological pattern, and tumor volume. For post-surgical status, only PFS was significantly higher in patients with complete resection (3y-PFS of 75%, p=0.008). The mean survival time in patients <3 yo was 1.9 years, and the mean survival time in patients >3 yo was 2.5 years. The genetic alterations found were SMARCB1, NOTCH1, and KMT2D. CONCLUSION Patients >3yo seem to have a higher OS and PFS than those <3 yo. Early diagnosis of ATRT may corroborate to a better outcome. The radiotherapy in the first treatment can improve the outcome of patients under 3 years of age. The classic histological pattern was associated with worse PFS.

Clinical and MRI risk factors predicting post-irradiation carotid blowout syndrome in patients with nasopharyngeal cancer.

To explore the clinical and imaging features of nasopharyngeal cancer (NPC) complicated by acute carotid blowout syndrome (CBS), analyze the risk factors for CBS, and improve diagnostic vigilance for early intervention. This retrospective review was conducted between January 2003 and May 2023. Altogether, 49patients with post-irradiation NPC with CBS and 49patients without CBS as control group were enrolled. The condition of the patients when CBS occurred was reviewed. Patient characteristics of the CBS and control groups were compared, and binary logistic regression analysis was performed to identify risk factors for CBS. All patients in the CBS group were conscious, and 41patients had aKarnofsky performance assessment scale score of ≥ 70. After interventional therapy, 43patients survived (the mean survival time of patients after CBS was 3.2 ± 2.1years). Compared with the control group, the CBS group had ahigher incidence of sphenoid sinusitis (81% vs. 52.4%), osteonecrosis (82.9% vs. 51.2%), artery exposure (29.3% vs. 4.9%), and internal carotid artery injury (61% vs. 29.3%). Osteonecrosis and artery exposure were selected as important risk factor for CBS, with p-values of 0.016 and 0.031, respectively. CBS is an important factor that affects the survival of patients with NPC. If internal carotid artery injury, artery exposure, sphenoid sinusitis, and osteonecrosis are present, especially the latter two signs, the possibility of CBS should be considered.

Small cell osteosarcoma: An NCDB analysis of demographic and socioeconomic factors of diagnosed patients.

e23504 Background: Small cell osteosarcoma (SCOS) is a rare subtype of osteosarcoma accounting for roughly 1.5% of all osteosarcomas. Its prognosis is slightly worse than conventional osteosarcoma. Exploring demographic trends in patients with a confirmed SCOS diagnosis may provide insight into its epidemiology and allow for earlier diagnosis. The National Cancer Database (NCDB) was analyzed to research the demographic factors in patients diagnosed with SCOS. Methods: A retrospective cohort analysis utilizing the 2004–2020 National Cancer Database (NCDB) included patients with a histologically-confirmed diagnosis of SCOS (ICD-O-3 9185). Demographic factors (age, sex, race, Hispanic status, educational attainment, insurance status, facility type, distance from facility, and Charles-Deyo score) were analyzed via descriptive statistics. Incidence trends were interpreted in regression analysis. The mean survival was compared using the Log Rank (Mantel-Cox) test. Results: A cohort of 102 cases of SCOS were retrieved from the NCDB between 2004–2020. The primary sites for SCOS were the long bones of the lower limb (41%). Most patients were male (69%), White (63%), non-Hispanic (84%) with a mean age for diagnosis of 28 (SD = 18). The mean survival for males was 117 months (95% CI [93,141]), more than twice as long as females with 58 months (95% CI [31,85]). The Log Rank (Mantel-Cox) test reported a chi-square (χ²) value of 6.434, indicating a statistically significant difference between survival curves of males and females (p = 0.01). Residence in a metropolitan area (86%) was more common than other rural or urban areas. The greatest proportion of patients lived in the Middle or South Atlantic region of the United States (68%). The majority of patients were insured (86%), with the most covered by private insurance (64%) or Medicaid (22%). The median household income for each patient was most commonly in the highest quartile of over $74,063 (29%). Patients were diagnosed with SCOS at a steady rate between 2004 to 2020 (R² = 0.0956). Using the AJCC Cancer Staging System, most patients were Stage II (40%) or Stage IV (21%) at diagnosis. As a primary treatment, 87% of patients received chemotherapy. Most patients (91%) had no comorbidities with a Charlson-Deyo score of 0. Conclusions: This is the first time that demographic and socioeconomic factors of SCOS patients have been analyzed from the NCDB, revealing that the mean survival time of patients after receiving a diagnosis was more than double for males than females. SCOS patients are also more likely to live in metropolitan areas, particularly within the Middle or South Atlantic United States. Consistent with earlier reports, SCOS is typically diagnosed in young adults in the long bones of lower limbs. To better understand the impact of demographic factors on the diagnosis, treatment, and overall survival of patients with SCOS, further research is recommended.

Utility of Clinical Variables for Deciding Palliative Care in Paraquat Poisoning: A Retrospective Study.

Patients with paraquat poisoning (PP) have a mortality rate comparable to that of advanced malignancies, yet palliative care is seldom considered in these patients. This audit aimed to identify triggers for early palliative care referral in critically ill patients with PP. Medical records of patients with PP were audited. Predictors of mortality within 48 hours of hospitalization and 24 hours of intensive care unit (ICU) admission were considered as triggers for palliative care referral. Among 108 patients, 84 complete records were analyzed, and 53 out of 84 (63.1%) expired. Within 48 hours after hospitalization, the lowest oxygen partial pressure in arterial blood to a fraction of inspired oxygen [the ratio of partial pressure of oxygen in arterial blood (PaO2) to the fraction of inspiratory oxygen concentration (FiO2) (PaO2/FiO2)] was the independent predictor of mortality, cut-off ≤ 197; the area under the curve (AUC), 0.924; sensitivity, 97%; specificity, 78%; p <0.001; and 95% confidence interval (CI): 0.878-0.978. Kaplan-Meier survival plot showed that the mean survival time of patients with the lowest PaO2/FiO2, ≤197, was 4.64 days vs 17.20 days with PaO2/FiO2 >197 (log-rank p < 0.001). Sequential organ failure assessment (SOFA) score within 24 hours of ICU admission had a cut-off ≥9; AUC, 0.980; p < 0.001; 95% CI: 0.955-1.000; 91% sensitivity; and 90% specificity for mortality prediction. Out of the total of 84 patients with PP analyzed, there were 11 patients admitted to the high dependency units (13.1%) and 73 patients admitted to the ICU (86.9%). Out of the total of 84 patients of PP in whom data was analyzed, 53 (63.1%) patients required ventilator support. All the 53 patients who required ventilator support due to worsening hypoxemia, eventually expired. The lowest PaO2/FiO2 ≤ 197 within 48 hours of hospitalization, SOFA score ≥9 within 24 hours of ICU admission or need for mechanical ventilation are predictors of mortality in PP patients, who might benefit from early palliative care.

Increased coexpression of PD-L1 and IDO1 is associated with poor overall survival in patients with NK/T-cell lymphoma.

Immunotherapy with programmed cell death 1 ligand 1 (PD-L1) blockade was effective in patients with NK/T-cell lymphoma. In addition to PD-L1, indoleamine 2,3-dioxygenase-1 (IDO1) is one of the most promising immunotherapeutic targets. High proportions of PD-L1 and IDO1 proteins were observed by immunohistochemistry (IHC) from 230 newly diagnosed patients with NK/T lymphoma with tissue samples from three cancer centers and were associated with poor overall survival (OS) in patients with NK/T lymphoma. Importantly, the coexpression of PD-L1 and IDO1 was related to poor OS and short restricted mean survival time in patients with NK/T lymphoma and was an independent prognostic factor in the training cohorts, and which was also validated in 58 NK/T lymphoma patients (GSE90597). Moreover, a nomogram model constructed with PD-L1 and IDO1 expression together with age could provide concise and precise predictions of OS rates and median survival time. The high-risk group in the nomogram model had a positive correlation with CD4 + T-cell infiltration in the validation cohort, as did the immunosuppressive factor level. Therefore, high PD-L1 and IDO1 expression was associated with poor OS in patients with NK/T lymphoma. PD-L1 and IDO1 might be potential targets for future immune checkpoint blockade (ICB) therapy for NK/T lymphoma.

Tumour stage and overall survival in patients with intrahepatic cholangiocarcinoma and primary sclerosing cholangitis – a retrospective cohort study

Abstract Background Patients with primary sclerosing cholangitis (PSC) carry increased risks for malignancy, among which cholangiocarcinoma (CCA) is the most frequent. We aimed to characterise a cohort of patients with PSC and intrahepatic CCA (iCCA) and to compare this cohort with CCA in different localisations. Methods We performed a retrospective analysis of our medical database from 01.01.2007 to 30.06.2023 and differentiated CCA according to its localisation within the biliary tract into iCCA, perihilar CCA (pCCA), distal CCA (dCCA), and gallbladder carcinoma (GBC). Results We identified 8 (28%) patients with iCCA, 14 (48%) patients with pCCA, 6 (21%) patients with GBC, and 1 (3%) patient with dCCA without significant differences in gender distribution and mean age. Mean time between diagnosis of PSC and CCA was 158±84 months for iCCA, 93±94 months for pCCA, and 77±69 months for GBC (p=0.230). At the time of CCA diagnosis, advanced-stage disease was present in 6 (75%) patients with iCCA, 13 (93%) patients with pCCA, and 2 (40%) patients with GBC (p=0.050). Only 5 (63%) patients with iCCA received curatively intended surgery, of whom 4 (80%) patients developed recurrence after a mean time of 38±31 months. Mean survival time in patients with iCCA (35±33 months) lay between patients with pCCA (14±8 months) and patients with GBC (57±58 months), but the difference was not statistically significant (p=0.131). Conclusion Patients with PSC and iCCA showed an advanced tumour stage at diagnosis and limited long-time survival, which was classified between pCCA with worse prognosis and GBC with better prognosis.

Combined Computed Tomography Angiography-Computed Tomography Perfusion in the Identification and Prognostic Assessment of Myocardial Bridging from the CORE320 Study: 5-Year Follow-Up

Our objective is to use computed tomography angiography (CTA) and computed tomography perfusion (CTP) to identify the ischemic significance of myocardial bridging (MB). We also seek to determine the long-term prognostication of MB in the presence or absence of obstructive coronary artery disease (CAD). The CORE320, a prospective, multicenter study including 381 patients with known or suspected CAD clinically referred for invasive coronary angiography who underwent combined (CTA-CTP) and single-photon emission computed tomography before conventional coronary angiography. The incidence of MB was identified in 135 patients (35.4%) with 93.9% identified in the left anterior descending artery. MB were divided as partially encased versus fully encased. There was no difference in ischemia identified between partially encased MB and fully encased MB (37 [40%] vs 25 [35%], p=0.54]. Ischemia was identified at similar rates in partially versus fully encased MB by single-photon emission computed tomography at (8 [9%] vs 8 [11%], p=0.57] and CTP (34 [37%] vs 21 [30%], p=0.33]. There was no difference in the primary outcome of 5-year outcome of combined incidence of myocardial infarction or death. The restricted mean survival time in patients with CTA with <50% stenosis with or without a MB was 4.906 years (95% confidence interval 4.759 to 5.000) and 4.891 years (95% confidence interval 4.718 to 5.000), respectively (p=0.824). Cardiac computed tomography perfusion imaging can assess both anatomic and functional significance of myocardial bridging with diagnostic accuracy similar to current standard imaging. Furthermore, 5-year cardiovascular events were not different with the presence of MB in both obstructive and non-obstructive CAD.

Anaplastic thyroid cancer with life-threatening symptoms in an older female - a case report

&#x0D; Introduction: Anaplastic thyroid cancer, also called undifferentiated, is an uncommon and highly aggressive thyroid neoplasm that usually occurs in patients above 60 years of age (mean 65 years). Incidence is about 1-2 cases per million persons a year. [11] It accounts for 1-2% of thyroid cancer cases and probably develops from previously differentiated thyroid neoplasms. [1] Mutations of TP53 gene are most common and exist in 17-80% of patients. Other frequently mutated genes are RAS, BRAF and β-catenin. [3] The metastatic spread tends to occur through hematogenous and lymphatic pathways. The neoplasm presents as a rapidly enlarging neck mass that can cause compression on the neck structures giving symptoms such as dysphagia and dyspnea. Patients with established diagnosis of anaplastic thyroid cancer have very poor prognosis. Mean survival time of patients after confirmed diagnosis is 3 to 6 months and 5-year survival rate is estimated to be 5-14%. [2]&#x0D; &#x0D; &#x0D; Aim: The aim of this study is to portray the clinical presentation, course and complications of a patient suffering from anaplastic thyroid cancer. This case report includes performed procedures and implemented treatment.&#x0D; &#x0D; &#x0D; Description of the case: We present a case of an 87-year-old female that was admitted to the hospital with a large thyroid mass, symptoms of dysphagia, dyspnea and significant weight loss. Clinical picture was suspicious of anaplastic thyroid cancer. Further workup included laboratory testing, imaging and FNA biopsy. Surgical procedure of tracheostomy was conducted due to life-threatening dyspnea with consecutive patient’s monitoring in Intensive Care Unit. After achieving clinically stable state the patient was transferred to Clinical Department of Radiotherapy where palliative radiotherapy was initiated.&#x0D;

#5679 PATIENT OUTCOME IN A SWEDISH SINGLE-CENTRE COHORT OF ANCA-ASSOCIATED VASCULITIS WITH RENAL INVOLVEMENT

Abstract Background and Aims End-stage kidney disease and premature death are common in patients with antineutrophil cytoplasmic antibody (ANCA) -associated vasculitis (AAV) with renal involvement. Poor patient outcome is attributed to multiple factors comprising a delay in diagnosis and treatment, inadequate efficacy of treatments, and complications due to toxic effects of given immunosuppressive therapy. The aim of the present study was to evaluate clinical and prognostic features of a Swedish cohort of patients with renal AAV and to investigate the pattern of immunosuppressive treatment and predictors of renal and patient survival. Method Ninety-one patients diagnosed with AAV with renal involvement between 01 March 2002 and 30 October 2018 in a single-centre were included in the present retrospective study. Results Among these ninety-one patients, 52 (57%) were diagnosed with PR3-ANCA, and 39 (43%) with MPO-ANCA. Patients with PR3-ANCA and MPO-ANCA were received comparable induction therapy. However, the frequency of PLEX was significantly higher in patients with PR3-ANCA versus MPO-ANCA (44% vs. 21% respectively; P = 0.025). Overall renal survival at 1- and 5-year was 91% and 69% respectively with no significant differences between patients with PR3-ANCA and MPO-ANCA. Overall, 1-year and 5-year patient survival was 92% and 77% respectively. The overall survival time mean was11.5 years and 95% confidence interval (CI) of 9.9 to 13.0 years. Mean survival time in patients with PR3-ANCA was 10.8; 95% CI 8.8 to 12.7 years versus 11.7; 95% CI 9.6 to 13.8 years in those with PR3-ANCA. Cox regression analysis showed that advancing age significantly predicted higher mortality risk, whereas MPO-ANCA subtype significantly predicted lower mortality risk (Figure 1). Infection (25%), malignancy (22%), and cardiovascular events (16%) were the major causes of death in the present cohort. In a subgroup of thirty-two patients with eGFR &amp;lt;15 ml/min per 1.73 m2 or undergoing dialysis at time of diagnosis. Twenty-three patients (72%) were treated with PLEX, whereas 9 patients (28%) did not receive PLEX as a part of remission induction therapy. Treatment with PLEX had no effects on overall 1-year patient and renal survival Conclusion In this cohort of patients with AAV with renal involvement the overall 1-year renal and patient survival were high. Advancing age significantly predicted higher mortality risk, while MPO-ANCA subtype significantly predicted lower mortality risk. Treatment with PLEX had no effects on 1-year patient and renal survival in a subgroup of patients with severe renal involvement with AAV.

Correlation and clinical significance of VISTA expression and cervical squamous cell carcinoma

Objective: To explore the relationship between the expression of the T-cell activation suppressor-immunoglobulin variable region (VISTA) and the development of cervical squamous cell carcinoma (CSCC), and the impact on the prognosis of CSCC patients. Methods: Cervical tissue samples from 116 CSCC, including 23 cervical intraepithelial neoplasia (CIN) grade I, 23 CIN grade Ⅱ-Ⅲ, and 23 chronic cervicitis patients, were collected from the First Hospital of Soochow University between March 2014 and April 2019. The expression of VISTA in each group was detected by immunohistochemistry (IHC). Survival data of CSCC patients were obtained by follow-up. The survival analysis was performed by Kaplan-Meier method, and survival differences between groups were compared by Log rank test. Prognostic impact factors were analyzed using a multifactorial Cox proportional hazards model. Results: The positive rate of VISTA expression in CSCC group was 32.8% (38/116), and which of grade Ⅱ-Ⅲ was 17.4% (4/23). VISTA expression results showed no positive expression patients in the cervical intraepithelial neoplasia grade I and chronic cervicitis groups. The differences between the CSCC group and other groups were statistically significant (P<0.01). In 116 CSCC patients, VISTA expression was associated with International Federation of Gynecology and Obstetrics (FIGO) stage and lymph node metastasis (P<0.01). The mean survival time of patients in the VISTA positive expression group was 30.7 months, and the 3-year survival rate was 44.7% (17/38). However, the mean survival time of the patients in the VISTA negative expression group was 49.1 months, and the 3-year survival rate was 87.2% (68/78). The Cox regression model found that VISTA expression positivity (P=0.001) and FIGO stage (P=0.047) were prognostic factors for CSCC, and patients with VISTA-positive CSCC had a 4.130-fold risk of death higher than those with VISTA-negative expression. Conclusions: The VISTA protein is highly expressed in CSCC tissues, and its expression level is closely related to the occurrence and development of CSCC. The expression of VISTA can be used as an independent predictor of CSCC prognosis and can provide a strong basis for the treatment of CSCC with immune checkpoint inhibitors.

Effect of Peripheral Blood Lymphocytes on Prognosis of Multiple Cancers.

In the era of immunotherapy, the immune function of patients with cancer has attracted increasingly more attention. The immune scoring system is an important supplement to the classical tumor staging and classification process. The immune system plays a controversial role in the development of cancer. Meanwhile, the prognostic significance of peripheral blood lymphocytes is still controversial. The present study aimed to assess the prognostic significance of peripheral blood lymphocytes in eight types of cancers. We performed a retrospective analysis of 32731 patients with cancer hospitalized in Shanxi Cancer Hospital from January 2012 to December 2016. The percentages of CD3+, CD4+, CD8+, CD19+, CD56+, and CD127+ lymphocytes in the peripheral blood of all patients were examined using flow cytometry. The immune cell subsets of patients with cancer were classified into three groups using the K-means clustering method via the R language software. Differences in the overall survival rate were analyzed using the Kaplan-Meier method. The Cox regression model was utilized for univariate and multivariate analysis. The mean survival time of patients with liver cancer, rectal cancer, gastric cancer, breast cancer, esophageal cancer, colon cancer, ovarian cancer, and lymphoma was 30.25, 21.74, 37.67, 16.28, 21.62, 30.25, 31.43, and 34.27 months, respectively. The survival curves showed that the most prognostically beneficial immune state of the patients was when the expression of the immune cells in the peripheral blood was in equilibrium. Moreover, Cox proportional hazards regression model analysis revealed that the factors affecting the overall survival (OS) of patients with eight different kinds of cancer were not identical. However, CD19+ lymphocytes had the most significant impact on the prognosis of these patients. Cancer occurrence and development were associated with the density of lymphocyte infiltration. Thus, immune homeostasis could be an effective indicator to evaluate prognosis and judge cancer treatment.

Erythrocytosis, thrombocytosis, and rate of recurrent thromboembolic event-A population based cohort study.

The management to reduce risk of thromboembolic complications in polycythemia vera and essential thrombocythemia are well established, but for other conditions with elevated hemoglobin, hematocrit, or platelets there are no consensus regarding treatment and follow up. To assess frequency of elevated blood values in patients with thromboembolic event, how many of these should be investigated further regarding myeloproliferative neoplasm and if the risk of recurrent event is depending on underlying condition. Retrospective cohort study of 3931 adult patients in the county of Norrbotten, Sweden, with thromboembolism during 2017 and 2018. Of the 3931 patients, 1195 had either elevated Hb, HCT, or platelets fulfilling the 2016 revised WHO criteria for PV and ET, and out of these 411 should be evaluated regarding underlying myeloproliferative neoplasms. Unexplained thrombocytosis and secondary erythrocytosis were associated with the highest rate of recurrent event as well as the most inferior restricted mean survival time. Elevated blood values are common in patients with thromboembolic event and the high risk of recurrent event and inferior restricted mean survival time in patients with unexplained thrombocytosis and secondary erythrocytosis implicates the importance of finding and managing the underlying condition.

Better survival and prognosis in SCLC survivors after combined second primary malignancies: A SEER database-based study.

With recent advances in treatment modalities, the survival time for patients with small cell lung cancer (SCLC) has increased, along with the likelihood of recurrence of a second primary tumor. However, patient treatment options and prognosis remain uncertain. This research evaluated the survival rates of patients with SCLC with a second malignancy, aiming to provide new insights and statistics on whether to proceed with more active therapy. SCLC patients were selected based on the Surveillance, Epidemiology, and End Results (SEER) database, updated on April 15, 2021. We defined those with SCLC followed by other cancers (1st of 2 or more primaries) in the sequence number as S-second primary malignant cancer (S-SPM). Those who had other cancers followed by SCLC (2nd of 2 or more primaries) were defined as OC-SCLC. We performed Kaplan-Meier survival analysis, life table analysis, univariate analysis, stratified analysis, and multiple regression analysis of patient data. We considered the difference statistically meaningful at P < .05. After selection, data for 88,448 participants from the SEER database was included in our analysis. The mean survival time for patients with S-SPM was 69.349 months (95% confidence interval [CI]: 65.939, 72.759), and the medium duration of survival was 34 months (95% CI: 29.900, 38.100). Univariate analysis showed that for overall survival, the hazard ratio (HR) of S-SPM was 0.367 (95% CI: 0.351, 0.383), which was 0.633 lower than that of patients with solitary SCLC and 0.606 lower than that of patients with OC-SCLC. For cancer-specific survival (CSS), the HR of S-SPM was 0.285 (95% CI: 0.271, 0.301), which was 0.715 lower than for patients with solitary SCLC and 0.608 lower than that for patients with OC-SCLC. Multiple regression analysis showed that the HR values of S-SPM were lower than those of patients with single SCLC and those with OC-SCLC, before and after adjustment for variables. Kaplan-Meier survival curves showed that patients with S-SPM had significantly better survival times than the other groups. The survival time and prognosis of patients with S-SPM were clearly superior to those with single SCLC and OC-SCLC.

Resection or Biopsy: The Efficacy of Different Surgical Approaches for Primary Central Nervous System Lymphoma.

To analyze the efficacy of surgical resection versus brain biopsy combined with postoperative chemotherapy for primary central nervous system lymphoma (PCNSL) and to discuss a clinically standardized treatment protocol. Patients with a pathological diagnosis of PCNSL and subsequent chemotherapy between 2016 and 2021 at Northern Jiangsu People?s Hospital were selected and divided into groups according to whether they underwent microsurgical resection or stereotactic needle biopsy. Statistical analyses were performed to compare efficacy and safety in the two groups. A total of 21 patients with PCNSL were identified, of whom 12 underwent resection and 9 underwent diagnostic stereotactic biopsy only. Compared with the resection group, the biopsy group had a higher proportion of deep tumors (55.6% vs. 8.3%, p=0.016), and the mean intraoperative bleeding was significantly reduced (13.33 ± 6.61 mL vs. 170.83 ± 101.04 ml, p < 0.001). In addition, the mean survival time of patients who died during the postoperative follow-up period was shorter (6.83 ± 1.60 vs. 18.56 ± 10.20 months, p=0.016), and the one-year survival rate was lower (33.3% vs. 83.3%, p=0.032). There was no significant difference between the two groups in terms of the mean progression-free survival time or new functional impairment after surgery. For PCNSL, patients who undergo surgical resection have a better outcome than those who undergo biopsy only, suggesting that when the tumor is located at a surgically resectable site, surgical resection should be actively chosen; when the tumor is located at a deep and unresectable site, brain biopsy should be chosen.

The Systemic Inflammation Marker NLR as a Prognostic Factor in Complicated Colorectal Cancer

Many recent scores based on the inflammatory response, such as Neutrophil Lymphocyte Ratio (NLR), Platelet Lymphocyte Ratio (PLR), Lymphocyte Monocyte Ratio (LMR) have been demonstrated to have a prognostic value in cancer patients. The ratio between neutrophils and lymphocytes is a very useful tool, most studies admitting its role as a prognostic marker in cancer. We made a retrospective study on 391 patients hospitalized and operated in emergency for complicated colorectal cancer in the Surgery II clinic of the "St. Ap. Andrei" from Galati, Romania, between 2008-2017. We demonstrated that the increased preoperative value of NLR was a negative prognostic factor for long-term survival in patients with complicated colorectal cancer (HR = 7.581, 95% CI = (6.358,9.039) (p = 0.000000)). The cut-off point is &gt; 2.61, with sensitivity of 73.61 and specificity of 100.00. The mean survival time in patients with NLR &lt; = 2.61 was 39,676, 95% CI = (37,189, 42,163) and in those with NLR &gt; 2.61 it was 12,504, 95% CI = (11,747, 13,261), the difference between the survival time of patients with values ​​above the cutoff and below the cutoff being statistically significant (p = 0.000000, Log-Rank).

Outcomes and Complications of Pelvic Chondrosarcomas Treated Using Navigation Guidance and Multidisciplinary Approach: Is the Tumor Volume a Prognostic Factor?

(1) Background: Pelvic Chondrosarcomas (CS) have a poor prognosis. The grade is the most important survival predictor; other factors are periacetabular location and Dedifferentiated CS subtype. The aim of the study is to investigate a series of CS of the pelvis, to analyze the prognostic factors that affect outcomes and to demonstrate how the use of intraoperative navigation can reduce the complications without worse outcomes. (2) Methods: Retrospective study on 35 patients (21 M, 14 F), median age at surgery 54 years (IQR 41−65), with pelvic CS, treated with hemipelvectomy under navigation guidance. (3) Results: 30 high-grade CS and 5 low-grade CS; mean follow-up 51.4 months. There was a positive linear correlation between the tumor volume and the presence of local recurrence at follow-up. The mean survival time of patients with larger chondrosarcoma volume was lower, but not significantly so. Lower MSTS score was associated with significantly lower survival time (p < 0.001). (4) Conclusion: in this series overall survival, LR and distant metastasis were comparable with recent literature, while complication rate was lower compared to similar series without the use of navigation. There was a correlation between tumor volume and local recurrence rate but not with the presence of metastasis at follow up.

Serum zinc values, ankle brachial index and mortality in hemodialysis patients

IntroductionThe atherosclerotic state of haemodialysis (HD) patients may be influenced by heavy metals. The purpose of our study was to assess the relationship between serum zinc (Zn) ankle brachial index (ABI) as a non-invasive diagnostic tool for atherosclerosis, and mortality in chronic haemodialysis (HD) patients.MethodsSixty one HD patients were included (mean age 61.2 ± 13.8 years). The ABI was measured with an automated measuring device (ABPI MD, MESI®, Slovenia). Two groups of patients were formed based on the median value of Zn (14.1 mcmol/l). The average observation time was 2.8 years. Comorbidities (arterial hypertension (AH), diabetes mellitus (DM), dyslipidaemia), smoking and oral nutritional supplements (ONS) consumption were noted. Survival rates were analysed by Kaplan–Meier and Cox regression was used to determine the influence of Zn, ABI, AH, DM, dyslipidaemia, smoking and ONS.ResultsZn values were between 9.2 and 23.5 mcmol/l (14.4 ± 2.34), ABI values ranged from 0.8 to 1.4 (1.14 ± 0.12). Patients with lower Zn values had lower ABI (p = 0.036). Mean survival time of patients with higher Zn values was 985 days ± 277 days and with lower Zn values 1055 ± 143 days. Six (19.4%) patients with lower Zn and five (16.7%) patients with higher Zn died. We found statistically insignificant lower survival in patients with higher Zn. We failed to find any predictor of all-cause mortality, except for ONS consumption (95% CI 1.6–33.3; p = 0.012).ConclusionsLower Zn is associated with lower ABI in HD patients, but we found no impact of Zn on patient survival.

Survival Analysis in Patients with Lung Cancer and Subsequent Primary Cancer: A Nationwide Cancer Registry Study.

With improved survival in patients with cancer, the risk of developing multiple primary malignancies (MPMs) has increased. We aimed to characterize MPMs involving lung cancer and compare these characteristics between patients with single lung cancer and those with lung cancer and subsequent primary cancer (known as lung cancer first [LCF]). Methods: This retrospective study was conducted based on Taiwan Cancer Database from Taiwan’s National Health Insurance Registry Database. Patients with lung cancer (n = 72,219) from 1 January 2011 to 31 December 2015, were included in this study, and their medical records were traced back to 1 January 2002, and followed until 31 December 2019. Results: MPMs occurred in 10,577 (14.65%) patients with lung cancer, and LCF and other cancer first (OCF) accounted for 35.55% and 64.45% of these patients, with a mean age at lung cancer diagnosis of 65.18 and 68.92 years, respectively. The median interval between primary malignancies in the OCF group was significantly longer than that in the LCF group (3.26 vs. 0.11 years, p < 0.001). Patients in the single lung cancer group were significantly older than those in the LCF group (67.12 vs. 65.18 years, p < 0.001). The mean survival time of patients with LCF was longer than that of patients with single lung cancer. Following initial lung cancer, the three most common second primary malignancies were lung, colon, and breast cancers. For patients with advanced lung cancer, survival in patients with mutant epidermal growth factor receptor (EGFR) was longer than that in patients with undetected EGFR. In stage 3 and 4 patients with EGFR mutations, the LCF group showed better survival than the single lung cancer group. Conversely, in stage 1 patients with mutant EGFR, the LCF group exhibited worse survival than the single lung cancer group. Conclusions: Survival in patients with MPMs depends on baseline characteristics and treatments. Our findings may contribute to the development of precision medicine for improving personalized treatment and survival as well as the reduction of medical costs.

Analysis of Palliative Care Utilization and Medical Expenses among Patients with Chronic Diseases in Taiwan: A Population-Based Cohort Study.

Palliative care (PC) is an important alternative treatment for patients with chronic diseases, particularly for those in the later stages of disease progression. This is because these diseases are often irreversible, with progressive worsening of symptoms. By encouraging the use of tranquility resources for good death and spiritual relief, PC can reduce the physical and psychological burden on patients at the end of their lives. Currently, most discussions on PC have focused on patients with cancers, and few have further discussed the differences in medical expenses between PC and emergency treatment in patients with chronic diseases at the end of their lives. This study analyzed the top three chronic diseases in patients who used PC resources in the past decade and identified the impact of emergency treatment on mean survival time and medical expenses based on the medical records from the National Health Insurance Research Database. In total, 4061 patients with chronic diseases who were admitted to hospice wards were included in this study; of them, 85 patients still received emergency treatment, including urinary catheterization, nasogastric intubation, and respirator use, at the end of their lives. The mean survival time of patients aged 50–64 years who received emergency treatment was longer than that of the same age group who did not receive emergency treatment. Different comparisons of the mean survival time and medical expenses using real-world data provides important insights regarding PC management that may assist in establishing health policies in the future.
