Purpose
We designed and evaluated the clinical performance of a plasma circulating tumor DNA (ctDNA) panel of 112 genes in various subtypes of lymphoma.
Materials and Methods
Targeted deep sequencing with an error-corrected algorithm was performed in ctDNA from plasma samples that were collected before treatment in 42 lymphoma patients. Blood buffy coat was utilized as a germline control. We evaluated the targeted gene panel using mutation detection concordance on the plasma samples with matched tissue samples analyzed the mutation profiles of the ctDNA.
Results
Next-generation sequencing analysis using matched tissue samples was available for 18 of the 42 patients. At least one mutation was detected in the majority of matched tissue biopsy samples (88.9%) and plasma samples (83.3%). A considerable number of mutations (40.4%) that were detected in the tissue samples were also found in the matched plasma samples. Majority of patients (21/42) were diffuse large B cell lymphoma patients. The overall detection rate of ctDNA in patients was 85.7% (36/42). The frequently mutated genes included PIM1, TET2, BCL2, KMT2D, KLHL6, HIST1H1E, and IRF8. A cutoff concentration (4,506 pg/mL) of ctDNA provided 88.9% sensitivity and 82.1% specificity to predict ctDNA mutation detection. The ctDNA concentration correlated with elevated lactate dehydrogenase level and the disease stage.
Conclusion
Our design panel can detect many actionable gene mutations, including those at low frequency. Therefore, liquid biopsy can be applied clinically in the evaluation of lymphoma patients, especially in aggressive lymphoma patients.

Predictive Factors of Event-Free Survival at 24 Months in Patients with Peripheral T-Cell Lymphoma: A Retrospective Study: Yu Ri Kim, Soo-Jeong Kim, Hye Sun Lee, Soyoung Jeon, Hyunsoo Cho, Haerim Chung, Ji Eun Jang, June-Won Cheong, Yoo Hong Min, Jin Seok Kim; Cancer Res Treat. 2022;54(2):613-620.

Purpose
Event-free survival at 24 months (EFS24) is known to be a surrogate marker for overall survival (OS) for patients with peripheral T-cell lymphoma (PTCL). We examined the role of EFS24 in PTCL compared to diffuse large B-cell lymphoma (DLBCL), and then assessed the clinical predictive factors of achieving EFS24.
Materials and Methods
Patients with newly diagnosed PTCL treated with anthracycline-based chemotherapy were included. Subsequent OS was defined as the time elapsed from 24 months after diagnosis until death from any cause in those who achieved EFS24.
Results
Overall, 153 patients were evaluated, and 51 patients (33.3%) achieved EFS24. Patients who achieved EFS24 showed superior OS compared to patients who did not (p < 0.001). EFS24 could stratify the subsequent OS although it did not reach to that of the general population. After matching the PTCL group to the DLBCL group based on the international prognostic index, the subsequent OS in patients who achieved EFS24 was similar between the two groups (p=0.094). Advanced stage was a significant factor to predict the failing EFS24 by multivariable analysis (p < 0.001).
Conclusion
Patients with PTCL who achieve EFS24 could have a favorable subsequent OS. Since advanced disease stage is a predictor of EFS24 failure, future efforts should focus on developing novel therapeutic strategies for PTCL patients presenting with advanced disease.

HBsAg-Negative, Anti-HBc–Negative Patients Still Have a Risk of Hepatitis B Virus–Related Hepatitis after Autologous Stem Cell Transplantation for Multiple Myeloma or Malignant Lymphoma: Hyunsung Park, Do Young Kim, Soo-Jeong Kim, Haerim Chung, Hyunsoo Cho, Ji Eun Jang, June-Won Cheong, Yoo Hong Min, Jae-Woo Song, Jin Seok Kim; Cancer Res Treat. 2018;50(4):1121-1129.

Purpose
Although hepatitis B surface antigen (HBsAg)–negative, hepatitis B core antibody (anti-HBc)–negative patients are not considered to be at risk for hepatitis B virus (HBV)–related hepatitis, the actual risk remains to be elucidated. This study aimed to evaluate the risk of HBV-related hepatitis in HBsAg-negative, anti-HBc–negative patients receiving autologous stem cell transplantation (ASCT) for multiple myeloma (MM) or malignant lymphoma.
Materials and Methods
We retrospectively reviewed data from 271 HBsAg-negative patients (161 anti-HBc–negative and 110 anti-HBc–positive at the time of ASCT) who received ASCT for MM or lymphoma. The risk of HBV-related hepatitis was analyzed according to the presence of anti-HBc. HBV serology results at the time of ASCT were compared with those at the time of diagnosis of MM or lymphoma.
Results
Three patients (two anti-HBc–negative MMs and one anti-HBc–positive MM) developed HBV-related hepatitis after ASCT. The rate of HBV-related hepatitis did not differ among patients with or without anti-HBc status (p=0.843). HBV-related hepatitis more frequently occurred in MM patients than in lymphoma patients (p=0.041). Overall, 9.1% of patients (16.7% with MM and 5.4% with lymphoma) who were HBsAg–negative and anti-HBc–positive at the time of diagnosis had lost anti-HBc positivity during chemotherapy prior to ASCT.
Conclusion
Our data suggest that HBsAg-negative, anti-HBc–negative patients at the time of ASCT for MM or lymphoma still might be at a risk for HBV-related hepatitis.
