We report an unusual case of primary cutaneous CD30+ anaplastic large cell lymphoma in a 58-year-old man who presented with disseminated hyperpigmented patches, papules, and nodules. Our case is also unusual in that the patient did not respond to an intensive chemotherapy regimen in contrast to previously reported cases of primary cutaneous CD30+ anaplastic large cell lymphoma.

Primary esophageal lymphoma is very rare, and most reported cases are histologically mucosa-associated lymphoid tissue lymphoma. Therefore, the principle treatment strategy for primary esophageal lymphoma focuses on local treatments, such as endoscopic mucosal resection or radiation therapy, but systemic chemotherapy plays the central role in the treatment of diffuse large B cell lymphoma (DLBCL). Generally, standard treatment for DLBCL is six or three cycles of R-CHOP chemotherapy followed by involved field radiation therapy according to stage. However, the optimal treatment strategy for primary esophageal DLBCL, and the role of additional radiation is not settled, due to a paucity of cases. Moreover, the clinical characteristics related to the etiology and natural course are also unknown. Here, we present two cases of primary esophageal DLBCL with a literature review.

This paper reports a case of malignant histiocytic lymphoma mainly in the frontal region with intracranial extradural extension. Operation was performed to remove the mass but the tumor began to recur rapidly. And so under the condition that the operative wound was not fully healed, the patient received radiotheray and chemotherapy postoperatively, with remarkable regession of the tumor.

Primary cutaneous CD30+ lymphoproliferative disorders include primary cutaneous CD30+ (anaplastic) large T cell lymphoma, lymphomatoid papulosis, and borderline cases. These represent a clinical and histologic continuum rather than a separate entity. We report a 39-year-old woman with the clinical features of lymphomatoid papulosis. Histology favored primary CD30+ anaplastic large cell lymphoma. Although she was treated with aggressive combination chemotherapy, the lesions recurred shortly after discontinuation of chemotherapy. She is now regularly followed up without any treatment.

Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is rare among skin malignancies. C-ALCL usually manifests as reddish or violet nodules. Surgical excision or radiation therapy is generally considered as first-line therapy, but a clinically aggressive disease may require multiagent chemotherapy. Establishing a proper diagnosis of C-ALCL is challenging but should be made to avoid inappropriate treatment and its consequences. The authors report a case of medically resolved C-ALCL in an 81-year-old man presented with well-defined nodular lesions on the forehead.

Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare subtype of malignant non-Hodgkin lymphoma, in which 40% of the cases show spontaneous regression without aggressive treatment. Surgery and focal radiation therapy are the primary forms of treatment for this disease; however, if pcALCL is accompanied by multifocal skin lesions, chemotherapy is also common. The prognosis for pcALCL is generally excellent, with a 5-year survival rate of 85-100%. However, pcALCL with extensive limb disease typically has a poor prognosis. Here, we present a case of pcALCL with extensive limb disease that resulted in the patient's death, despite the use of aggressive chemotherapy.

BACKGROUNDRituximab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) significantly prolonged event-free survival in first-line chemotherapy for patients with diffuse large B-cell lymphoma (DLBCL). But relapse and refractory DLBCL occur frequently. Although rituximab is effective, its role in salvage therapy after autologous transplant remains unclear. Maintenance therapy with rituximab in responding patients after first line chemotherapy may be a useful novel approach capable of eradicating minimal residual disease and to bring survival benefit. This systematic review and meta-analysis evaluated the effects of rituximab maintenance treatment and salvage therapy of patients with DLBCL.

METHODSWe performed a systematic review and meta-analysis of randomized controlled trials and compared rituximab maintenance or salvage therapy at relapse with observation. We searched the Cochrane Library, PubMed, EMBASE, conference proceedings, databases of ongoing trials, and references of published trials. Two reviewers independently assessed the quality of the trials and extracted data. Hazard ratios for time-to-event data were estimated and pooled.

RESULTSSeven trials including 1470 DLBCL patients were included in this systematic review and meta-analysis. Patients treated with maintenance rituximab have better overall survival (OS) and event-free survival (EFS) than patients in the observation arm, but there was no statistical significance. Patients who received rituximab salvage therapy for relapse or refractory DLBCL have statistically significantly better OS [HR of death = 0.72, 95% CI (0.55-0.94), P = 0.02], progression-free survival (PFS) [HR = 0.61, 95% CI (0.52-0.72), P < 0.05], odds ratio (OR) [RR = 1.26, 95% CI (1.07-1.47), P = 0.004] than patients in the observation arm. The rate of infection-related adverse events was higher with rituximab treatment [RR = 1.37, 95% CI = (1.14 - 1.65) P =0.001].

CONCLUSIONSAfter first-line chemotherapy, the two rituximab-combined treatment strategies, including maintenance and salvage therapies can bring survival benefit. But due to the few studies, the low methodological quality assessment and the low outcome evidence quality, it's not confirmed that the two strategies are better than normal chemotherapy regimens. More high-quality randomized controlled trials are still needed to provide reliable evidence. The higher rate of infections after rituximab therapy should be taken into consideration when making treatment decisions.

OBJECTIVE: To investigate the effect of arsenic disulfide (AS METHODS: The human DLBCL cell OCI-LY3 was treated with different concentrations of AS RESULTS: The DLBCL cell viability was decreased significantly at 24, 48 or 72 h as cultured with itraconazole. Along with the increasing of itraconazole concentration, the DLBCL cell viability was significantly reduced as compared with that in control group, and the results showed statistically significant(r=-0.690，r=-0.639, r=-0.833, r=-0.808, r=-0.578). The inhibitory and apoptosis rates of the cells were significantly increased as compared with those of the single drug-treated group after treated by the combination of itraconazole and AS CONCLUSION Itraconazole can inhibit proliferation of DLBCL cells in a concentration-and time-dependent manner. In addition, the combination of AS

Objective: To investigate the potential value of CT Radiomics model in predicting the response to first-line chemotherapy in diffuse large B-cell lymphoma (DLBCL). Methods: Pre-treatment CT images and clinical data of DLBCL patients treated at Shanxi Cancer Hospital from January 2013 to May 2018 were retrospectively analyzed and divided into refractory patients (73 cases) and non-refractory patients (57 cases) according to the Lugano 2014 efficacy evaluation criteria. The least absolute shrinkage and selection operator (LASSO) regression algorithm, univariate and multivariate logistic regression analyses were used to screen out clinical factors and CT radiomics features associated with efficacy response, followed by radiomics model and nomogram model. Receiver operating characteristic (ROC) curve, calibration curve and clinical decision curve were used to evaluate the models in terms of the diagnostic efficacy, calibration and clinical value in predicting chemotherapy response. Results: Based on pre-chemotherapy CT images, 850 CT texture features were extracted from each patient, and 6 features highly correlated with the first-line chemotherapy effect of DLBCL were selected, including 1 first order feature, 1 gray level co-occurence matrix, 3 grey level dependence matrix, 1 neighboring grey tone difference matrix. Then, the corresponding radiomics model was established, whose ROC curves showed AUC values of 0.82 (95% CI: 0.76-0.89) and 0.73 (95% CI: 0.60-0.86) in the training and validation groups, respectively. The nomogram model, built by combining validated clinical factors (Ann Arbor stage, serum LDH level) and CT radiomics features, showed an AUC of 0.95 (95% CI: 0.90-0.99) and 0.91 (95% CI: 0.82-1.00) in the training group and the validation group, respectively, with significantly better diagnostic efficacy than that of the radiomics model. In addition, the calibration curve and clinical decision curve showed that the nomogram model had good consistency and high clinical value in the assessment of DLBCL efficacy. Conclusion: The nomogram model based on clinical factors and radiomics features shows potential clinical value in predicting the response to first-line chemotherapy of DLBCL patients.
