Incidence, Prognostic Factors and Survival Outcome in Patients With Primary Hepatic Lymphoma

Prediction model establishment of prognosis factors for acute myeloid leukemia based on the SEER database

Acute myeloid leukemia (AML) with t (9;11) (p22; q23) presents as a varied hematological malignancy. The t (9;11) (p22; q23) translocation is the most common among 11q23/KMT2A rearrangements in AML. This research aimed to develop a nomogram for precise prediction of overall survival (OS) and cancer-specific survival (CSS) in AML with the t (9;11) (p22; q23) translocation. We utilized the Surveillance, Epidemiology, and End Results (SEER) database to identify patients diagnosed with t (9;11) (p22; q23) AML from 2000 to 2021. Prognostic factors for this AML subtype were determined using least absolute shrinkage and selection operator (LASSO) regression, which guided the creation of prognostic nomograms. To evaluate the model's discrimination, accuracy, and effectiveness, we employed the concordance index (C-index), calibration charts, receiver operating characteristic curves (ROC), area under the curve (AUC), and decision-curve analysis (DCA). The research was meticulously planned, executed, and documented in full adherence to the TRIPOD guidelines. The nomogram was developed using key variables including age, race, first primary tumor, and chemotherapy. The concordance indices (C-indices) were 0.704 for OS and for 0.686 for CSS. Patients were classified into high-risk and low-risk groups based on nomogram scores, with significant differences in OS and CSS between these groups (P < 0.001). This study developed innovative nomograms that combine clinical and treatment factors to predict 1-, 3-, and 5-year survival rates for patients with t (9;11) (p22; q23) AML.

A Novel Age-Based Nomogram as the Best Predictor for Long-Term Overall Survival in Head and Neck Mucosa-Associated Lymphoid Tissue Lymphoma

OBJECTIVES

Head and neck mucosa-associated lymphoid tissue (MALT) lymphoma, a rare subtype of non-Hodgkin lymphoma, has received limited attention regarding its prognosis. This study aimed to illuminate the clinical characteristics and identify prognostic factors for head and neck MALT lymphoma, intending to develop an accessible tool for clinicians to predict long-term survival probabilities and inform therapeutic strategies.

METHODS

This multicentre retrospective study enrolled 424 head and neck MALT lymphoma patients from the Surveillance, Epidemiology, and End Results Program (SEER) database. Least absolute shrinkage and selection operator (LASSO)-Cox regression analysis identified independent prognostic factors for overall survival (OS), leading to the development of an age-based nomogram predicting OS probabilities at 5, 10, and 15 years. Evaluation included time-dependent receiver operating curve (ROC), calibration curves, and decision curve analysis.

RESULTS

Multivariate Cox analysis highlighted age exceeding 65 years [hazards ratio (HR): 2.97, 95% confidence interval (CI): 1.94-4.57; P < 0.001] and unmarried status (HR: 1.58, 95% CI: 1.07-2.33, P = 0.023) as significantly associated with shorter OS, while black race correlated with longer OS (HR: 0.25, 95% CI: 0.09-0.69, P = 0.007). The age-based nomogram, integrating these factors, demonstrated efficacy in predicting 5-year [area under the curve (AUC): 0.640] and 10-year OS (AUC: 0.705), with an impressive AUC of 0.842 for the 15-year OS probability in the training cohort. Decision curve analysis affirmed the nomogram's clinical utility, surpassing individual factors. Consistent results were observed in validation cohorts.

CONCLUSION

Our study provides crucial insights into head and neck MALT lymphoma, filling gaps in understanding its clinical landscape. The validated age-based nomogram serves as a practical tool for clinicians, offering enhanced prognostic precision and guiding personalized treatment strategies in this understudied lymphoma subtype.

Nomogram models predicting prognosis for patients with t(8;21) acute myeloid leukemia: a SEER-based study

BACKGROUND

Acute myeloid leukemia (AML) with t(8;21) manifests as a diverse hematological malignancy. Although it was categorized into a favorable subtype, 30-40% of patients experience relapse. The objective of this research was to devise a nomogram for the accurate anticipation of both overall survival (OS) and cancer-specific survival (CSS) in t(8;21) AML.

METHODS

From the Surveillance, Epidemiology, and End Results (SEER) database, individuals diagnosed with t(8;21) AML from 2000 to 2018 were selected. Prognostic factors for t(8;21) AML were identified using Cox regression analysis and Akaike Information Criterion (AIC), forming the basis for constructing prognostic nomograms.

RESULTS

Key variables, including first primary tumor, age group, race, and chemotherapy, were identified and integrated into the nomogram. The C-index values for the nomograms predicting OS and CSS were 0.753 (validation: 0.765) and 0.764 (validation: 0.757), respectively. Ultimately, based on nomogram scores, patients were stratified into high-risk and low-risk groups, revealing significant disparities in both OS and CSS between these groups (P < 0.001).

CONCLUSION

This study innovatively crafted nomograms, incorporating clinical and therapeutic variables, to forecast the 1-, 3-, and 5-year survival rates for individuals with t(8;21) AML.

Nomogram for predicting cardiovascular mortality in patients with gastrointestinal stromal tumor: A population-based study

This research aimed to develop and validate a clinical nomogram for predicting the probability of cardiovascular death (CVD) in patients with gastrointestinal stromal tumors (GIST). Information regarding patients diagnosed with GIST was extracted from the surveillance, epidemiology, and end results database. The multivariable competing risk model and multivariable Cox regression model were utilized to determine the independent predictive factors. A comparison was made between the results obtained from the 2 models. A nomogram was built to visualize the competing risk model. The nomogram's performance was assessed utilizing concordance index, calibrate curve, decision curve analysis, and risk stratification. A total of 9028 cases were enrolled for final analysis, with CVD accounting for 12.8% of all deaths since GIST diagnosis. The multivariate analysis of competing risks revealed that age, chemotherapy and marital status were identified as independent risk factors for CVD in GIST individuals. The nomogram model exhibited good calibration and strong discriminative ability, indicating its effectiveness in predicting outcomes, with a concordance index of 0.788 (95% confidence interval: 0.753-0.823) in the training set, and 0.744 (95% confidence interval: 0.673-0.815) in the validation set. Decision curve analysis indicated that the prediction model had good clinical practicability. Additionally, risk stratification analysis efficiently divided GIST individuals into high- and low-risk populations for CVD. This was the first research to construct and validate a predictive nomogram using a competing risk model to estimate the individual probabilities of CVD in GIST patients. The nomogram can assist clinicians in making personalized treatment and monitoring plans.

Primary hepatic lymphoma presenting as pyogenic liver abscess: A case report

BACKGROUND

Primary hepatic lymphoma (PHL) is a lymphoproliferative disorder confined to the liver without peripheral lymph node involvement and bone marrow invasion. PHL is extremely rare in clinical practice. The etiology and pathogenesis of PHL are largely unknown. There are no common standard protocols or guidelines for the treatment of PHL.

CASE SUMMARY

We report the case of a 66-year-old man who presented with fever and abdominal pain for three weeks. Computed tomography and magnetic resonance imaging scans showed a pyogenic liver abscess. The patient underwent a right posterior hepatectomy. The surgical pathology revealed aggressive B-cell lymphoma, with a primary consideration of diffuse large B-cell lymphoma of non-germinal center origin.

CONCLUSION

This article reviews the characteristics, mechanism and treatment of PHL and provides insight into the diagnosis of PHL.

Primary hepatic lymphoma a case report and literature review

RATIONALE

Primary hepatic lymphoma is a rare extranodal non-Hodgkin lymphoma that is primarily localized in the liver. It predominantly affects elderly males and presents with nonspecific laboratory findings, imaging results, and clinical symptoms, making diagnosis challenging. Histopathological examination serves as the gold standard for diagnosis, and treatment options include chemotherapy or surgical intervention combined with chemotherapy.

PATIENT CONCERNS

A 50-year-old male patient came to our hospital for treatment after finding a mass in his liver.

DIAGNOSES

Laboratory tests and clinical symptoms lack specificity for primary hepatic lymphoma, and imaging findings can be difficult to differentiate. Pathology is the gold standard.

OUTCOMES

The patient was dead.

CONCLUSION

A definitive diagnosis primarily relies on histopathological examination, and surgical resection combined with chemotherapy yields better treatment outcomes.

Primary hepatic lymphoma of MALT type mimicking hepatic adenoma treated by hepatectomy: a case report and literature review

Background

Primary hepatic lymphoma (PHL) is a rare malignant tumor. Extranodal marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT) is an indolent lymphoma occurring at extranodal sites. The stomach is the most common organ affected by MALT lymphoma, whereas liver-related lymphoma is rarely reported. Its atypical clinical presentation often delays the diagnosis. Owing to the rarity of PHL, identifying its optimal treatment still remains a challenge. Herein, we report a case of PHL of the MALT type mimicking hepatic adenoma that was treated by hepatectomy without chemotherapy and review the scarce literature. Our findings suggest that surgery is an alternative approach to cure patients with localized hepatic lymphoma.

Case summary

A 55-year-old woman was admitted to our hospital because of upper abdominal discomfort, and a liver lesion was detected by computed tomography. She did not have nausea, fever, fatigue, jaundice, weakness, night sweats, or weight loss before admission. And her previous medical history was unremarkable. There were no positive signs on physical examination. Based on her preoperative examination including magnetic resonance imaging, the liver lesion was suspected to be a hepatic adenoma; however, the possibility of it being a malignancy like hepatocellular carcinoma was not excluded. Therefore, a decision of resection of the lesion was made. During the operation, hepatectomy of segment 4b and cholecystectomy were performed. The patient recovered well; however, after postoperative pathological examination, the lesion was diagnosed as a hepatic lymphoma of MALT type. The patient was reluctant to undergo chemotherapy or radiotherapy. At 18-month follow-up, no significant recurrence was observed, indicating that the treatment had a curative effect.

Conclusion

Notably, primary hepatic lymphoma of MALT type is a rare, low-grade B-cell malignancy. Making an accurate preoperative diagnosis of this disease is usually difficult, and liver biopsy is an appropriate avenue to improve the diagnostic accuracy. In patients with a localized tumor lesion, hepatectomy followed by chemotherapy or radiotherapy should be considered to achieve better outcomes. Although this study describes an unusual type of hepatic lymphoma mimicking a benign tumor, it has its inherent limitations. More clinical studies are required to establish guidelines for the diagnosis and treatment of this rare disease.

Lymphoepithelial carcinoma of the head and neck: a SEER analysis of prognostic factors for survival

OBJECTIVE

To explore the epidemiological characteristics of patients with lymphoepithelial carcinoma (LEC) of the head and neck and the prognostic factors.

METHODS

We conducted a retrospective cohort study of cases of head and neck LEC retrieved from the Surveillance, Epidemiology and End Results database. Kaplan-Meier survival analysis and the log-rank test were employed to assess overall survival (OS) and cancer-specific survival (CSS). Univariate and multivariate analyses were used to construct Cox regression models. We established nomograms to predict OS and CSS among patients with nasopharyngeal LEC, who were divided into high- and low-risk groups based on the OS nomograms to compare the effects of treatment using the restricted mean survival time (RMST).

RESULTS

The 5-year OS and CSS rates of the cohort were 70.8% and 74.8%, respectively. Advanced age, unmarried status, black race, distant metastasis, and the absence of surgical treatment were significantly associated with decreased survival rates. RMST did not differ between the combined treatment (radiotherapy and chemotherapy) and radiotherapy monotherapy groups, but chemotherapy alone displayed poor efficacy.

CONCLUSIONS

Head and neck LEC is associated with a favorable prognosis. Radiotherapy plays a significant role in managing patients with nasopharyngeal LEC, which is influenced by multiple prognostic factors.

CLINICAL AND PATHOLOGICAL CHARACTERIZATION OF HEPATIC LYMPHOMAS: A RETROSPECTIVE SINGLE-CENTER STUDY

BACKGROUND

The incidence of hepatic lymphoma has been increasing recently and diagnosis can be challenging as clinical presentation and radiological findings are usually variable and non-specific.

OBJECTIVE

The aims of this study were to describe their main clinical, pathological and imaging characteristics and identify poor prognostic factors.

METHODS

A retrospective study that included all patients with histological diagnosis of liver lymphoma over a 10-year period at our center was performed.

RESULTS

A total of 36 patients were identified, with mean age of 56.6 years and male predominance (58%). There were three patients with primary liver lymphoma (8.3%) and 33 with secondary liver lymphoma (91.7%). The most common histological type was diffuse large B-cell lymphoma (33.3%). The most common clinical manifestations included fever, lymphadenopathy, weight loss, night sweats and abdominal discomfort; three patients (11.1%) were asymptomatic. Computed tomography scan revealed heterogenous radiological patterns including a single nodule (26.5%), multiple nodules (41.2%) or diffuse infiltration (32.4%). The mortality rate during follow-up was 55.6%. Higher levels of C-reactive protein (P=0.031) and absence of treatment response (P<0.001) were significantly associated with higher mortality.

CONCLUSION

Hepatic lymphoma is a rare disease that may involve liver as part of a systemic disease or, less commonly, be confined to this organ. Clinical presentation and radiological findings are often variable and non-specific. It is associated with high mortality and poor prognostic factors include higher levels of C-reactive protein and absence of response to treatment.

Cardiovascular Outcomes in the Patients With Colorectal Cancer: A Multi-Registry-Based Cohort Study of 197,699 Cases in the Real World

PURPOSE

We aimed to investigate the mortality patterns and quantitatively assess the risks of cardiovascular death (CVD) in patients with colorectal cancer (CRC). We also established a competing-risk model to predict the probability of CVD for patients with CRC.

PATIENTS AND METHODS

Patients with CRC who diagnosed between 2007 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database were included in the present study. The cumulative incidence function (CIF) was used for CVD and other causes of death, and Gray's test was used to determine the subgroup difference in CIF. The Fine-Gray proportional subdistribution hazards model was used for identifying independent risk factors for CVD. A novel competing-risk model was established to evaluate the probability of CVD for patients with CRC. The performance of the nomogram was measured by concordance index (C-index), calibration curve, decision curve analysis (DCA), and risk stratification.

RESULTS

After a median follow-up of 37.00 months, 79,455 deaths occurred, of whom 56,185 (70.71%) succumbed to CRC and 23,270 (29.29%) patients died due to non-CRC, among which CVD accounted for 9,702 (41.69%), being the major cause of non-cancer deaths. The 1-, 3-, and 5-year cumulative rates for CVD were 12.20, 24.25, and 30.51%, respectively. In multivariate analysis, age, race, marital status, tumor size, tumor stage, advanced stage, surgery, and chemotherapy were independent risk factors of CVD among patients with CRC. The nomogram was well calibrated and had good discriminative ability, with a c-index of 0.719 (95% CI, 0.738-0.742) in the training cohort and 0.719 (95% CI, 0.622-0.668) in the validation cohort. DCA demonstrated that nomogram produced more benefit within wide ranges of threshold probabilities for 1-, 3-, and 5-year CVD, respectively.

CONCLUSION

This study was the first to analyze the CIF and risk factors for CVD among CRC based on a competing-risk model. We have also built the first 1-, 3-, and 5-year competing nomogram for predicting CVD. This nomogram had excellent performance and could help clinicians to provide individualized management in clinical practice.

Investigation of epidemiological characteristics and development of a nomogram to predict survival in primary ocular adnexal lymphoma

BACKGROUND

Studies on the epidemiology and prognosis of primary ocular adnexal lymphoma (POAL) are scarce for its low occurrence. The goal of our research was to assess the epidemiologic characteristics, prognostic variables and survival of POAL patients.

METHODS

The Surveillance, Epidemiology and End Results (SEER) database was used to collect data on patients identified with POAL from 1975 to 2011 and the incidence rate of POAL from 1975 to 2017. To discover independent predictive markers for overall survival (OS) and disease-specific survival (DSS), multivariable Cox regression analysis was utilised. The independent prognostic factors found by multivariate Cox regression analysis were used to generate a nomogram.

RESULTS

A total of 2839 patients were diagnosed with POAL, with an average age of 64.1 years. The total incidence of POAL was 2.51/1000000 (according to the overall adjustment of the 2000 American standard) from 1975 to 2017, and the annual percentage change (APC) was 2.47 (95% confidence interval 1.64-3.32, p < 0.05), showing a sharp upward trend. After multivariate Cox regression analysis, age, gender, year of diagnosis, marital status, primary site, laterality, pathological type and treatment strategy were evaluated as independent prognostic factors of OS or DSS (p < 0.05). A nomogram was constructed to forecast the DSS of 1, 3, 5 and 10 years. The concordance index (C-index) and the calibration plots demonstrated the robustness and accuracy of the nomogram.

CONCLUSIONS

Although POAL is sporadic, the incidence has generally increased in the past 36 years. In recent years, survival rates have risen, and radiotherapy can render better OS and DSS. The nomogram specially made for POAL is robust and precise in predicting the DSS of 1, 3, 5 and 10 years.

Imaging mimickers of cholangiocarcinoma: a pictorial review

Cholangiocarcinoma (CCA) is the second most common primary hepatobiliary malignancy and presents as three separate morphological subtypes; namely mass-forming, periductal-infiltrating, and intraductal-growing patterns. Each of these subtypes have distinct imaging characteristics, as well as a variety of benign and malignant mimics, making accurate diagnosis of CCA on imaging challenging. Whilst histopathological examination is required to arrive at a definitive diagnosis, it is still important for radiologists to be cognizant of these entities and provide reasonable differential diagnoses, as these potentially have a large impact on patient management. This pictorial essay illustrates the three morphological subtypes of CCA, as well as some important mimics for each subtype, that are encountered in clinical practice.

Clinical management and susceptibility of primary hepatic lymphoma: A cases-based retrospective study

BACKGROUND

The liver as a primary site of lymphoma is rarely seen, they are usually misdiagnosed as hepatocellular carcinoma, etc. In 2017, a review of primary hepatic lymphoma (PHL) was done in immunocompetent diffuse large B-cell lymphoma (DLBCL) patients. Yet questions that include treatment choosing or susceptibility of immunoincompetent patients remain disputable.

AIM

To investigate the clinical characteristics of patients with PHL.

METHODS

We collected PHL cases on PubMed, and extracted demographic and clinicopathological data to perform a systematic analysis. Survival analysis regarding age, lactate dehydrogenase (LDH), liver function abnormality (LFA), and treatment modalities were conducted. The Kaplan-Meier method and Cox regression were used to identify risk factors.

RESULTS

Of 116 PHL patients with DLBCL (62.1%) as the most common subtype. Biopsy methods before surgery produced a 97% positive rate. Progression-free survival (PFS) was significantly shortened in patients with elevated LDH [Hazard ratio (HR): 3.076, 95% confidence interval (CI): 1.207-7.840, P = 0.018] or LFA (HR: 2.909, 95%CI: 1.135-7.452, P = 0.026). Univariate Cox regression analysis suggesting that LDH, liver function, B symptom, hepatosplenomegaly, and lesion were significantly associated with PHL patients survival (P < 0.05). Heavy disease burden was observed in deceased patients. A few PHL patients (3.4%) have slightly higher tumor markers.

CONCLUSION

PHL patients with elevated LDH and LFA tend to have shorter PFS. Biopsy before treatment in undecided patients with no tumor markers exceeds upper limits has the most essential clinical significance, especially in immunoincompetent patients.
