Multiple primary malignancies - hepatocellular carcinoma combined with splenic lymphoma: A case report.

BACKGROUND: Primary liver cancer is one of the most common malignant tumours, while primary splenic lymphoma is a rare malignancy. Thus, cases of hepatocellular carcinoma (HCC) combined with splenic lymphoma are extremely rare. CASE SUMMARY: We present a 62-year-old woman who was admitted to the Interventional Radiology Department with a lump in the spleen and liver as well as multiple enlarged lymph nodes visible by ultrasound. Contrast-enhanced computed of the abdomen revealed a circular, low-density, shallow mass (approximately 2.6 cm in diameter) in the left intrahepatic lobe and multiple round, low-density shadows in the spleen with clear boundaries (maximum diameter 7.6 cm). Based on the characteristic clinical symptoms and explicit radiological findings, the clinical diagnosis was HCC with metastasis to the liver portal, retroperitoneal lymph nodes, and spleen. After transcatheter arterial chemoembolization and sequential radiofrequency ablation, the -fetoprotein level returned to the normal range, and the hepatitis B cirrhosis improved. In addition, splenic tumour biopsy confirmed the diagnosis of primary malignant lymphoma, which went into remission after chemotherapy. CONCLUSION: HCC with primary splenic non-Hodgkin lymphoma is extremely rare and easily misdiagnosed. Better understanding would facilitate early diagnosis, treatment and prognosis.

Percutaneous biliary stent combined with brachytherapy using 125I seeds for treatment of unresectable malignant obstructive jaundice: A meta-analysis.

BACKGROUND: Malignant obstructive jaundice (MOJ) is a common pathologic manifestation of malignant biliary obstruction. Recently, several clinical trials have explored the clinical effectiveness of intraluminal 125I seed-based brachytherapy for MOJ patients, and various outcomes have been reported. AIM: To assess the efficacy and safety of percutaneous biliary stents with 125I seeds compared to conventional metal stents in patients with unresectable MOJ. METHODS: A systematic search of English-language databases (PubMed, Embase, Cochrane Library, and Web of Science) was performed to identify studies published prior to June 2020 that compared stents with or without 125I seeds in the treatment of unresectable MOJ. The outcomes analyzed included primary outcomes (stent patency and overall survival) and secondary outcomes (complications and liver function parameters). RESULTS: Six randomized controlled trials and four retrospective studies involving 875 patients were eligible for the analysis. Of the 875 included patients, 404 were treated with 125I seed stents, while 471 were treated with conventional stents. Unadjusted pooled analysis demonstrated that compared to conventional stents, 125I seed stents extended the stent patency time [hazard ratio (HR) = 0.36, 95% confidence interval (CI) = 0.28-0.45, P < 0.0001] and overall survival period (HR = 0.52, 95%CI = 0.42-0.64, P < 0.00001). Subgroup analyses based on the type of 125I seed stent and type of study design showed consistent results. However, there were no significant differences in the occurrence of total complications [odds ratio (OR) = 1.12, 95%CI = 0.75-1.67, P = 0.57], hemobilia (OR = 1.02, 95%CI = 0.45-2.3, P = 0.96), pancreatitis (OR = 1.79, 95%CI = 0.42-7.53, P = 0.43), cholangitis (OR = 1.13, 95%CI = 0.60-2.13, P = 0.71), or pain (OR = 0.67, 95%CI = 0.22-2, P = 0.47). In addition, there were no reductions in the levels of serum indices, including total bilirubin [mean difference (MD) = 10.96, 95%CI = -3.56-25.49, P = 0.14], direct bilirubin (MD = 7.37, 95%CI = -9.76-24.5, P = 0.4), alanine aminotransferase (MD = 7.52, 95%CI = -0.71-15.74, P = 0.07), and aspartate aminotransferase (MD = -4.77, 95%CI = -19.98-10.44, P = 0.54), after treatment. Publication bias was detected regarding the outcome overall survival; however, the conclusions were not changed after the adjustment. CONCLUSION: Placement of stents combined with brachytherapy using 125I seeds contributes to a longer stent patency and higher overall survival than placement of conventional stents without extra complications or severe liver damage. Thus, it can be considered an effective and safe treatment for unresectable MOJ.

The correlation between CT features and insulin resistance levels in patients with T2DM complicated with primary pulmonary tuberculosis.

The aim is to investigate the correlation between computed tomography (CT) features and insulin resistance levels in patients with type 2 diabetes mellitus (T2DM) complicated with primary pulmonary tuberculosis (PTB). Nearly, 268 untreated PTB patients complicated with T2DM were divided into two groups according to the optimal cutoff value of HOMA-IR score for the Chinese population: HOMA-IR ≤ 2.69 (Group I: 74 patients), >2.69 (Group II: 194 patients). The basic characteristics and changes of CT manifestations were analyzed. In the two groups, the detection rate of large segmented leafy shadow was 39.2% and 78.9%; the air bronchogram sign detection rate was 40.5% and 80.9%; the discovery rate of mouth-eaten cavity was 33.8% and 73.7%; the thin-walled cavity detection rate was 2.7% and 16.0%; the rate of multiple cavities was 35.1% and 69.6%; and bronchial tuberculosis was found in 4.1% and 35.6%, respectively. The detection rates of lesions in Group II were significantly higher than in Group I (p < .05). HOMA-IR was found independently associated with large segmented leafy shadow, air bronchial sign, thin-walled cavity, and bronchial tuberculosis. The level of insulin resistance can effectively reflect the severity of PTB patients with T2DM. CT scan can directly provide image information in clinics. These two examinations can guide clinicians to accurately formulate subsequent treatment plans.

The efficacy and safety of erlotinib compared with chemotherapy in previously treated NSCLC: A meta-analysis.

Background: An increasing number of patients with advanced non-small cell lung cancer (NSCLC) have a poor prognosis and develop progressive disease after receiving conventional treatments. In recent years, several novel therapies have been approved for later lines of therapy of previously treated NSCLC. Erlotinib, an EGFR tyrosine kinase inhibitor, was recommended as the second-line therapy for pre-treated patients. However, the use of erlotinib has been reported to represent different clinical effects and adverse effects. Objectives: The current study was aim to investigate the efficacy and safety of erlotinib versus chemotherapy in pre-treated patients with advanced NSCLC. Methods: Electronic databases were searched for eligible literatures updated on June 2018. Randomized-controlled trials assessing the efficacy and safety of erlotinib in pre-treated NSCLC were included, of which the main outcomes were ORR (objective response rate), PFS (progression-free survival), OS (overall survival) and AEs (adverse events). All the data were pooled with the corresponding 95% confidence interval using RevMan software. Sensitivity analyses and heterogeneity were quantitatively evaluated. Results: A total of 11 randomized controlled trials were included in this analysis. The group of erlotinib did not achieved benefit in progression-free survival (OR = 0.61, 95%CI = 0.33-1.12, P = 0.11), overall survival (OR = 0.98, 95%CI = 0.84-1.15, P = 0.81) as well with the objective response rate (OR = 0.77, 95%CI = 0.36-1.63, P = 0.49), respectively. In the results of subgroup analysis among the patients with EGFR wild-type, there is also no significant differences in overall survival with erlotinib (OR = 0.90, 95%CI = 0.78-1.04, P = 0.15) and progression-free survival (OR = 0.33, 95%CI = 0.09-1.18, P = 0.09). The most common treatment-related adverse events in the erlotinib group is rash (OR = 5.79, 95%CI = 2.12-15.77, P = 0.0006), and neutropenia (OR = 0.02, 95%CI = 0.01-0.10, P ≤ 0.00001) is more found in the control group. In addition, fatigue (P = 0.09) and diarrhea (P = 0.52), the difference between the two groups had no statistical significance. Conclusions: There was no significant difference noted with regard to efficacy and safety between erlotinib vs. chemotherapy as the later-line therapy for previously treated patients with NSCLC, even with subgroup patients who have wild-type EGFR tumors. While, erlotinib might increase the risk of rash, and decrease the risk of neutropenia, compared with the chemotherapy. Further research is needed to develop a database of all EGFR mutations and their individual impact on the differing treatments.
