Lung cancer remains a leading cause of cancer mortality worldwide, including in Korea. Systemic therapy including platinum-based chemotherapy and targeted therapy should be provided to patients with stage IV non-small cell lung cancer (NSCLC). Applications of targeted therapy, such as an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) and anaplastic lymphoma kinase (ALK) inhibitors, in patients with NSCLC and an EGFR mutation or ALK gene rearrangement has enabled dramatic improvements in efficacy and tolerability. Despite advances in research and a better understanding of the molecular pathways of NSCLC, few effective therapeutic options are available for most patients with NSCLC without druggable targets, especially for patients with squamous cell NSCLC. Immune checkpoint inhibitors such as anti-cytotoxic T lymphocyte antigen-4 or anti-programmed death-1 (PD-1) or programmed death-ligand 1 (PD-L1) have demonstrated durable response rates across a broad range of solid tumors, including NSCLC, which has revolutionized the treatment of solid tumors. Here, we review the current status and future approaches of immune checkpoint inhibitors that are being investigated for NSCLC with a focus on pembrolizumab, nivolumab, atezolizumab, durvalumab, and ipilimumab.

OBJECTIVETo study the clinical features and treatment outcome of children with mature B-cell non-Hodgkin's lymphoma (B-NHL).

METHODSA total of 28 previously untreated children with mature B-NHL were enrolled and given the chemotherapy regimen of CCCG-B-NHL-2010. Among them, 20 were given rituximab in addition to chemotherapy. The children were followed up for 31 months (ranged 4-70 months). A retrospective analysis was performed for the clinical features of these children. The Kaplan-Meier method was used for survival analysis. A univariate analysis was performed to investigate the prognostic factors.

RESULTSAmong the 28 children, 17 (61%) had Burkitt lymphoma, 8 (29%) had diffuse large B-cell lymphoma (DLBCL), and 3 (11%) had unclassifiable B-cell lymphoma. As for the initial symptom, 13 (46%) had cervical mass, 10 (36%) had maxillofacial mass, 9 (32%) had hepatosplenomegaly, 5 (18%) had abdominal mass, and 5 (18%) had exophthalmos. Of all children, 14 had a lactate dehydrogenase (LDH) level of <500 IU/L, 3 had a level of 500-1 000 IU/L, and 11 had a level of ≥ 1 000 IU/L. After two courses of chemotherapy, 21 children achieved complete remission and 7 achieved partial remission. At the end of follow-up, 24 achieved continuous complete remission and 4 experienced recurrence. The 2-year event-free survival rate was (85.7± 6.6)%. The children with bone marrow infiltration suggested by bone marrow biopsy, serum LDH ≥500 IU/L, and bone marrow tumor cells >25% had a low 2-year cumulative survival rate.

CONCLUSIONSThe CCCG-B-NHL 2010 chemotherapy regimen combined with rituximab has a satisfactory effect in the treatment of children with B-NHL. Bone marrow infiltration on bone marrow biopsy is associated with poor prognosis.

To investigate the clinical efficacy and toxicities for the NAPD regimen (vinorelbine, cytarabine, cisplatin, and dexamethasone) in the treatment of recurrent refractory diffuse large B-cell lymphoma.
 Methods: A total of 30 patients identified with recurrent refractory diffuse large B-cell lymphoma were enrolled in this retrospective study. The curative efficacy of NAPD regimen was evaluated after 2 consecutive cycles. The toxicities and adverse reaction were evaluated after 1 cycle. The objective response rate (ORR), overall survival (OS), progress free survival (PFS), and the rates of 1, 2, and 4-year OS and PFS were analyzed. The prognosis was evaluated with univariate analysis.
 Results: The ORR was 56.7% and clinical benefit rate (CBR) was 83.3% after 2 cycles. Five patients achieved complete remission, 12 achieved partial remission, and 8 achieved stable disease. The median OS was 22 (1.5-140) months. The 1, 2, and 4-year OS rates were 59.1%, 48.2%, and 40.2%, respectively. The median PFS was 14 (1.5-140) months. The 1, 2 and 4-year PFS rates were 56.3%, 42.2%, and 31.7%, respectively. The main adverse reaction was myelosuppression. Three patients suffered from grade III-IV leukopenia and 1 thrombocytopenia. Grade I-II gastrointestinal toxicity was 20%. No heart, liver, and kidney damages at grade III-IV were observed.
 Conclusion: The NAPD regimen is effective and its toxicity is well tolerated for the treatment of recurrent refractory diffuse large B-cell lymphoma. It is a salvage chemotherapy regimen worth to be verified.

To determine clinical and pathologic profiles for anaplastic large cell lymphoma (ALCL).
 Methods: The clinical data of 22 patients with ALCL were analyzed retrospectively. Therapentie effect of different treatment strategies on ALCL was evaluated.
 Results: The median age for these patients was 32(9-70) years old and the patients with positive ALK accounted for 68.2% (15/22). All patients underwent chemotherapy, including regiments of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone), CHOPE (CHOP plus etoposide) or BEACOP (CHOP plus etoposide and bleomycin). Fourteen (63.6%) patients achieved initial complete remission (CR) and the CR rate for patients with ALK+ was significantly higher than that of patients with ALK- (P<0.05), while the age, gender, stage, beta 2-microglobulin (2-MG) level, lactate dehydrogenase (LDH) level, B symptoms had no significant effect on the rate of CR (P>0.05). After a median follow-up of 41 (2-150) months, 12 patients were overall survival, the median progression free time was 22.5 (2-150) months, and the age, gender, stage, IPI index, ALK expression level, beta 2-MG level, LDH level, and B symptoms had no significant effect on the rate of overall survival (P>0.05).
 Conclusion: ALK-positive occurs mainly in ALCL patients. The chemotherapy is still the main treatment, and CHOPE regimen is a better initial treatment scheme because the most patients show good prognosis.

Despite the decreasing incidence and mortality from gastric cancer, it remains a major health problem worldwide. Ninety percent of cases are adenocarcinomas. Here, we report a case of gastric adenocarcinoma developed after successful treatment of prior primary gastric diffuse large B-cell lymphoma (DLBCL). Our patient was an elderly man with primary gastric DLBCL in whom complete remission was achieved after R-CHOP (cyclophosphamide, adriamycin, vincristine, prednisolone plus rituximab) chemotherapy. Helicobacter pylori infection persisted despite adequate treatment leading to sustained chronic gastritis. The mean time to diagnose metachronous gastric carcinoma was seven years. We believe that a combination of many risk factors, of which chronic H. pylori infection the most important, led to the development of gastric carcinoma following primary gastric lymphoma. In summary, patients who have been successfully treated for primary gastric lymphoma should be followed up at regular short intervals. H. pylori infection should be diagnosed promptly and treated aggressively.

OBJECTIVETo investigate the neurocognitive function of children with acute lymphoblastic leukemia (ALL) and long-term disease-free survival and related influencing factors.

METHODSA total of 40 ALL children with long-term disease-free survival were enrolled as study group, and 40 healthy children were enrolled as control group. The Chinese Wechsler Intelligence Scale for Children (C-WISC), continuous performance test (CPT), and Stroop test software were used for the evaluation of all children. Neurocognitive function was compared between groups and influencing factors were analyzed.

RESULTSCompared with the control group, the study group had significantly lower full intelligence quotient, verbal intelligence quotient, and performance intelligence quotient in C-WICS (P<0.05) and significantly higher numbers of mistakes and misses in CPT (P<0.05). There were no significant differences in the numbers of correct answers, mistakes, and misses of word-color consistency between the study group and the control group (P>0.05), while the study group had significantly higher numbers of mistakes and misses of word-color contradiction and irrelevance (P<0.05). The total dose of high-dose methotrexate and ALL risk classification were associated with the reduction in intelligence quotient, and children's younger age at diagnosis of ALL was associated with the higher numbers of misses and mistakes. Girls tended to have a significantly lower performance intelligence quotient than boys (P<0.05).

CONCLUSIONSALL children with long-term disease-free survival have neurocognitive impairment, which may be associated with the dose of chemotherapeutic drugs, age at diagnosis, and sex.

BACKGROUND/AIMS: Recently, large cohort studies regarding associations between autoimmune disease and lymphomas have been reported in a few Western countries. However, Asian data concerning autoimmune-related lymphomas are limited. Therefore, we evaluated the clinical characteristics and prognostic factors of patients with autoimmune disease-related non-Hodgkin lymphoma (NHL) in a single center in Korea. METHODS: We analyzed the data from 11 patients with autoimmune-related NHL. Patients were categorized into two groups, those with rheumatoid arthritis (RA) and those with non-RA-related NHL. Then patients were re-categorized into a group with methotrexate (MTX) usage and a MTX non-usage group. Histological subtype, MTX duration, autoimmune disease duration, treatment modalities, and other data were collected and analyzed. RESULTS: Our study revealed that older RA patients have a greater likelihood of occurrence of NHL (p = 0.042). We confirmed that MTX duration and cumulative dose of MTX have no significant correlation with autoimmune disease and NHL (p = 0.073). In the management of autoimmune disease-related NHL, all patients were directly treated with systemic chemotherapy instead of employing a wait and watch approach. Overall survival (OS) and progression-free survival (PFS) in all autoimmune disease-related NHL were 100% and 87.5%, with no treatment-related mortality during the 2-year follow-up period of our study. CONCLUSIONS: Our study suggests that patients with RA-NHL are characterized by older age at onset compared to those with non-RA-NHL. Also considering of OS and PFS, intensive treatment strategy instead of delayed watchful managements may be required for autoimmune disease-related NHL including of old age group.

PURPOSE: To report a case of complete remission of primary orbital peripheral T-cell lymphoma with panniculitis-like features after chemotherapy. CASE SUMMARY: A 57-year-old healthy female presented with periorbital swelling and symptoms of diplopia. The patient was first treated with high-dose systemic corticosteroids, however, symptoms persisted. Therefore, anterior orbitotomy with excisional biopsy was performed for diagnostic purposes. On microscopic examination, the excised mass showed localized dense lymphocyte infiltrates, and cytologic atypia was observed under a high-power field. On immunehistochemical examination, tumor cells were positive for CD3 and CD8 but negative for CD4, CD20 and CD56. Based on histopathological results, primary orbital peripheral T-cell lymphoma with panniculitis-like features was diagnosed. Additionally, molecular pathological testing was positive for Epstein-Barr virus. Subsequently, the patients underwent chemotherapy and complete remission was obtained. CONCLUSIONS: Peripheral T-cell lymphoma often manifests as systemic symptoms, including lymph node enlargement and B symptom. The primary form of the disease in an orbit is very rare, and has a poor prognosis with a high mortality rate because the disease quickly progresses. Herein, the authors report a rare case of a healthy patient without any past medical history who achieved complete remission of a fast-growing primary orbital T-cell lymphoma with no preceding systemic symptoms.
