Anaplastic lymphoma kinase-positive (ALK+) diffuse large B-cell lymphoma (DLBCL) is a rare subtype of DLBCL. ALK+DLBCL has a characteristic immunoblastic/plasmablastic morphology, a distinct immunophenotypic profile, and recurrent cytoge-netic/molecular genetic abnormalities. The occurrence of this type of lymphoma has been reported in both adult and pediatric popula-tions. Although rare, this new entity should be recognized because most cases follow an aggressive clinical course with a poor progno-sis. The response of ALK+DLBCL to conventional chemotherapy is poor. The recently discovered small molecule ALK inhibitor may provide a potential therapeutic option for patients with this disease.

Olfactory neuroblastoma is a rare malignant tumor. Although multiple therapeutic modalities including surgery, radio-therapy, or chemotherapy could be used in patients with olfactory neuroblastoma, no standardized treatment has been achieved. This re-view introduces a case of adult olfactory neuroblastoma treated by a multiple disciplinary team in Tianjin Medical University Cancer In-stitute and Hospital. This review also aims to explore a complete set of diagnostic and treatment practices for the benefit of future pa-tients.

Objective:The occurrence of numerous tumors, particularly classical Hodgkin's lymphoma (CHL), is related with Ep-stein-Barr virus (EBV) infection. However, the incidence of CHL and its association with EBV varies significantly with ethnicity, geo-graphic location, sex, and age. This study investigated the association of EBV infection with CHL in Northern Chinese Han population. Methods:EBV-encoded small RNA (EBER) was detected in 136 cases of CHL through in situ hybridization. Results:A total of 37 cas-es were EBER positive (28%). The mixed cellularity (MC) subtype had the highest positive EBER rate of 49%(23/47;P<0.001), fol-lowed by lymphocyte-rich subtype with 30%(3/10), nodular sclerosis (NS) subtype with 14%(10/73), and 1ymphocyte depletion with 0%(0/2). Our study identified a single age distribution in the third decade. Moreover, NS subtype showed an evident single peak in the third decade. However, MC subtype had a lower peak in the fifth decade. The incidence of EBER showed a bimodal age distribution with two peaks in the first and fifth decades (21.6%and 24.3%, respectively). Conclusion:CHL in Northern Chinese Han population was associated with EBV infection, particularly the MC subtype.

Primary testicular lymphoma comprises 1% to 9% of testicular neoplasms and represents 1% to 2% of all non-Hodg-kin lymphomas. Histologically, the majority of the tumor consists of diffuse large B-cell non-Hodgkin lymphomas that are of intermedi-ate- or high-grade neoplasm. Clinically, the disease typically presents as a painless testicular swelling that develops over a span of weeks to months. B symptoms such as fever, weight loss, and anorexia are present in 25% to 41% of the patients. This tumor is an ag-gressive type, with frequent invasion of the epididymis, spermatic cord, and scrotum, as well as a marked tendency to relapse, especial-ly in the CNS. The treatment is mainly based on orchiectomy (mostly in stages ⅠE and ⅡE) regardless of its association with prophy-lactic irradiation of the scrotum and administration of intrathecal chemotherapy, cyclophosphamide, doxorubicin, vincristine, and pred-nisone regimen chemotherapy plus rituximab (R-CHOP) (stages ⅢE and ⅣE) and radiotherapy. The multi-modality treatment marked-ly improved progression-free and overall survival. We introduce as reference one case that received a multidisciplinary comprehensive discussion in the Department Lymphoma, Tianjin Medical University Cancer Hospital.

Anaplastic lymphoma kinase (ALK)-positive diffuse large B-cell lymphoma (DLBCL) is a rare and distinct variant of DLBCL. It is classified as a unique subtype of DLBCL in the 2008 WHO classification of lymphomas. No standard and effective therapeutic regi-men is available for ALK+DLBCL because it shows a more aggressive clinical course and frequent relapse. Therefore, a standardized and individualized treatment is needed to benefit more patients diagnosed with ALK+DLBCL through a multiple disciplinary team. This arti-cle presents a case of an ALK+DLBCL patient who relapsed after transplantation and was successfully treated with the ALK kinase inhibi-tor Crizotinib.
