Early stage mycosis fungoides (MF) has been treated with skin directed therapies including topical steroids, phototherapy (UVB), photochemotherapy (PUVA), topical nitrogen mustard, or total skin electron beam therapy. Recently, several studies have been reported that treat early-stage MF with narrow band UVB (NBUVB), which is an effective and convenient modality compared to other alternatives. Herein, we describe two cases of early stage MF treated with NBUVB. During the remission induction therapy, oral acitretin combined with NBUVB was used for several weeks to clear the MF, followed by treatment with only NBUVB for maintenance.

The major portion of Hodgkin lymphoma (HL) patients, even at an advanced stage can be cured with optimal initial treatment. ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) is the standard treatment regimen for the advanced stage HL, while Stanford V (doxorubicin, vinblastine, mechlorethamine, vincristine, bleomycin, etoposide, and prednisone) and escalated BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) can be reasonable alternatives for selected patients. Although radiotherapy is the key component in Stanford V regimen, radiotherapy should be applied only at the residual lymphoma in patients who received ABVD and BEACOPP therapy. These three representative treatments for advanced HL have individual advantages and disadvantages, so that the choice of the initial treatment should be dependent on patients' relapse risk, comorbidity, and age.

The localized early-stage of Mycosis fungoides (MF) (stage IA-IIA) is usually treated with topical agents, such as nitrogen mustard, steroids, and phototherapy (UVB/PUVA) as first line therapy; response to these initial treatments is usually good. However, hyperkeratotic plantar lesions are clinically rare and have decreased responsiveness to topical agents. For such cases, physicians may consider local radiotherapy. Here, a case of an 18-year-old Korean woman who was treated with three-dimensional conformal radiotherapy (3D-CRT) for hyperkeratotic plantar lesions that were refractory to UVA-1, methotrexate, and topical steroids is reported. Complete remission was attained after radiotherapy. During the one-year follow-up period, there has been no evidence of disease recurrence and no chronic complications have been observed.

OBJECTIVETo observe the clinical efficacy and side effects of brentuximab vedotin (BV) plus chlormethine hydrochloride (CH) in patients with relapsed and refractory Hodgkin lymphoma (HL) after failure with BV alone.

METHODSFrom March, 2014 to December, 2014, 6 patients who failed with BV monotherapy were enrolled in this study. The chemotherapy regimen consisted of BV (1.2-1.8 mg/kg, iv. gtt, d1) and CH (6 mg/m2, iv. gtt, d1) was given for 3 weeks as one course, and all patients received about 3-8 courses of chemotherapy, with an median of 4 courses. Clinical efficacy and adverse events were assessed and observed by radiographic examination and serological detection.

RESULTSAmong 6 patients, the overall response rate was 100% with 2 complete remission and 4 partial remission. The main adverse events were grade I (2 patients) and IV (2 patients) bone marrow depression, grade II (2 patients)gastrointestinal reaction, grade I (1 patient) increase of transaminase and myocardial enzyme and grade I (1 patient) mouth ulcers.

CONCLUSIONThe combination of BV and CH in the treatment of relapsed and refractory HL after failure with BV alone was high effective and the toxicities were well tolerable.

Woringer-Kolopp disease, also known as localized pagetoid reticulosis, is a rare variant of mycosis fungoides that presents as a solitary localized hyperkeratotic patch or plaque on the extremities and follows a benign course. Effective treatments for Woringer-Kolopp disease include skin-directed therapies such as topical nitrogen mustard, high-potency topical steroids, and phototherapy. Surgical excision has been pursued in cases of small, localized lesions. A 39-year-old man presented with a 3-month history of an asymptomatic plaque on his hand. Physical examination showed a 10-mm-diameter solitary round erythematous hyperkeratotic plaque with a slightly raised edge on the dorsum of his left hand. A skin biopsy revealed that numerous atypical lymphocytes had infiltrated the upper dermis and expanded into the epidermis with a pagetoid pattern. These atypical pagetoid cells were strongly positive for CD3, CD8, and T-cell intracellular antigen-1; focally positive for CD4; and negative for CD20, CD30, and CD56. A subsequent general examination revealed no evidence of systemic involvement and the lesion was treated with surgical excision. Here we report a rare case of Woringer-Kolopp disease.

PURPOSE: MOPP/ABV hybrid regimen incorporates MOPP and ABVD into a single regimen on the tenets of the Goldie-Coldman hypothesis. This study was performed to determine the efficacy of COPP/ABV hybrid regimen, in which cyclophosphamide was substituted for mechlorethamine, in patients with advanced Hodgkin's disease. MATERIALS AND METHODS: Patients with advanced Hodgkin's disease were treated with cyclophosphamide(600 mg/m2 iv, Dl), vincristine(1.4 mg/m2 iv, D1), procarbazine(100 mg/m2/d po, D1-7), prednisolone(40 mg/m2/d po D1-14), doxorubicin(35 mg/m2 iv, D8), bleomycin(10 mg/m2 iv, D8) and vinblastine(6 mg/m2 iv, D8). The treatment was repeated every 4 weeks. RESULTS: Between Aug. 1989 and Aug. 1996, 28 patients were enrolled. The median age was 33 years. Twenty one(75%) were previously untreated, newly diagnosed patients and 7(25%) were those who had relapsed after previous radiotherapy(RT). The common histologic types were nodular sclerosis(46%) and mixed cellularity(36%). Twenty three (82%) patients achieved complete remission(CR), three(11%) with the assistance of involved-field RT. Only one patient was primary treatment failure. The median follow-up duration was 56 months. Of the 23 patients achieving CR, three(13%) relapsed. Five-year relapse-free survival was 84.4%. Eight patients died. Five-year overall survival rate was 66.6% and 5-year failure-free survival rate was 66.3%. The survival rate of those who had relapsed after previous RT was significantly lower than that of newly diagnosed patients(P=0.03). The hematologic toxicities were common, but nonhernatologic toxicities were uncommon. Five patients died of treatment-related pneumonia or sepsis. Among them, four were those who had relapsed after previous RT. CONCLUSION: COPP/ABV hybrid regimen could cure significant proportion of patients with advanced Hodgkin's disease but the treatment-related mortality was high, especially in those who had relapsed after previous RT. Another regimen should be considered for those who received previous RT.

Cyclophosphamide, a cytotoxic alkylating agent, is widely used in various benign diseases like systemic lupus erythematosus (SLE), Wegener's granulomatosis, rheumatoid arthritis, nephrotic syndrome as well as in malignancies and organ transplantation. Cyclophosphamide is metabolized in the liver to various chlormethine metabolites and acrolein, which mediates the toxic effect to the urothelium and can cause hemorrhagic cystitis, bladder fibrosis, and has also been associated with urothelial malignancies including bladder cancer. It is known that SLE is not associated with an increased risk for the development of most of the solid tumors. But it has been suggested that the risk of the bladder cancer increases in patients with benign diseases such as SLE treated by cyclophosphamide. There are only very few reports of cyclophosphamide-induced bladder cancer in SLE so far. We report a case of a patient who developed bladder cancer 13 years after cyclophosphamide was given as therapy for SLE. This case shows that careful observation and urologic evaluation is undoubtedly important for patients treated with cyclophosphamide.

BACKGROUND: Overexpression of bcl-2 protein is observed both in follicular lymphoma, in which bcl-2 has usually undergone a translocation t (14;18). The experimental findings that transfection of bcl-2 in to murine lymphoid cells confers resistance to nitrogen mustard and camptothecin by inhibiting apoptosis suggests that bcl-2 overexpression may confer clinical drug resistance in lymphomas. In contrast to bcl-2, p53 arrests cells exposed to DNA-damaging agents in G1 to allow DNA repair or if essential repairs are not possible, promotes apoptosis. Experimentally, loss of p53 function produces cellular resistance to alkylating and topoisomerase-II drug classes, suggesting that loss of p53 function in lymphomas may cause drug resistance. These observations led to the hypothesis that bcl-2 and p53 play a role in the development of drug resistance in lymphoma. Although several studies assessed the association between bcl-2 expression and disease-free survival, they reached conflicting conclusions. METHODS: We analyzed tumor tissue from 42 patients with advanced NHL for p53 and bcl-2 expression and correlation with multiple clinical characteristics, response to therapy and overall survival. Among 42 tumors, 8 (19.0%) tumors had bcl-2 expression and 19 (45.2%) had a p53 overexpression. RESULTS: A significant correlation was found between bcl-2 expression and poor performance, advanced stage (stage III and IV) at diagnosis, and bone marrow involvement in a univariate analysis (P<0.05). A multivariate analysis showed that tumors with bcl-2 expression (>50%) were more likely to be poor prognosis than tumors with negative or week expression (<50%) and to have a shorter long-term survival (28.6% vs 75.5%; P<0.05). However, the expression of p53 did not correlate with any clinical characteristics and overall survival was not influenced by p53 protein expression. CONCLUSION: These results suggest that bcl-2 protein expression in patients with malignant lymphoma appears to be predictive of shorter long-term survival and it might be considered as a strong independent prognostic factor.

Chronic lymphocytic leukemia (CLL) is a unique indolent B-cell leukemia which is rare in Korea. Many patients with early stage CLL do not require immediate treatment, while those with advanced stage or symptoms need systemic chemotherapy. As our understanding about the pathophysiology of CLL increases, significant advances have been achieved in the treatment of this disease. Modern molecular genetics have been revealing remarkable heterogeneity of various genetic alterations and the corresponding prognostic stratification in CLL. The treatment of CLL had been developed from nitrogen mustard alkylating agent like chlorambucil to combination therapy including purine analogues like pentostatin and fludarabine until early 2000s. Since the introduction of targeted agent like anti-CD20 and anti-CD52 monoclonal antibodies in the treatment of CLL, the treatment outcome of CLL has leaped further. In conclusion, one of the current standard regimens in patients with untreated CLL is the combination of rituximab, cyclophosphamide and fludarabine. We recently passed the entrance for the era of targeted therapy, and are exploring various new agents and their combinations.
