Intravenous Immune Globulin (IVIG) Therapy After Unsuccessful Treatment with Corticosteroid and Cyclosporine A in Pfeifer-Weber-Christian Disease: A Case Report.

BACKGROUND Pfeifer-Weber-Christian disease (PWCD), also referred to as idiopathic nodular panniculitis, is a rare idiopathic disease characterized by lobular panniculitis of adipose tissue with systemic symptoms and multiple organ involvement and is usually treated with corticosteroids and cyclosporine A. We report a case of PWCD that was unresponsive to standard treatment but responded to intravenous immune globulin (IVIG) therapy. CASE REPORT A 35-year-old Korean woman presented with fever, malaise, myalgia, and painful nodules in the left breast. Histology of the breast nodules showed lobular panniculitis consistent with PWCD. She did not respond to corticosteroid and cyclosporine A. She was effectively treated with intravenous immune globulin (IVIG). IVIG therapy began with 60 g (1 g/kg) 4 times per week, 2 times every other week. Subsequently, the IVIG dose was reduced for maintenance therapy to 25 g (400 mg/kg) twice every other week and monthly. The patient showed immediate and dramatic improvement. General signs and symptoms, such as fever, malaise, and myalgia, were absent, and the masses had nearly subsided, with several very small hard nodules remaining for 3 months until the time of this report. CONCLUSIONS IVIG was an effective immunomodulatory therapeutic for PWCD in this case. This report shows that PWCD is a rare condition that is difficult to diagnose, but the histopathology of nodular panniculitis supports the diagnosis. In cases that do not respond to standard immunosuppressive therapy, including corticosteroids and cyclosporine A, IVIG therapy may lead to a favorable response with rapid symptomatic relief.

Diffuse alveolar hemorrhage from metastatic cardiac angiosarcoma of the lung successfully treated with paclitaxel chemotherapy: A case report and brief literature review.

Diffuse alveolar hemorrhage (DAH) is a life-threatening syndrome caused by various etiologies. DAH has rarely been reported to be associated with metastatic angiosarcoma. However, due to the rarity of complications, it may not be well-recognized by most clinicians. Herein, we report the case of a 70-year-old man with newly diagnosed metastatic cardiac angiosarcoma presenting with DAH. After an immediate bronchoalveolar lavage study and bronchoscopic biopsy, the patient was successfully treated with paclitaxel chemotherapy. Although most patients with this phenomenon have an extremely grave prognosis in previous literature, our experience showed that appropriate evaluation and treatment may be beneficial.

Brain metastasis from uterine cervical cancer.

Uterine cervical cancer usually spreads by local extension and through the rich lymphatic network to the retroperitoneal lymph nodes. However, brain metastasis from primary cervical cancer is extremely rare. They are usually seen late in the clinical course and have poor prognosis. We present a 48-year-old woman with squamous cell carcinoma of the cervix who developed multiple brain metastases after 30-month treatment of the primary disease. The patient received whole brain radiation therapy and steroids, and she is alive without any neurologic symptoms and signs at the 6-month follow-up after treatment of the recurrence.

[Hepatitis B virus reactivation during chlorambucil and prednisolone treatment in an HBsAg-negative and anti-HBs-positive patient with B-cell chronic lymphocytic leukemia].

It is generally accepted that seroconversion of hepatitis B virus (HBV) surface antigen (HBsAg) to an antibody to HBsAg (anti-HBs) indicates clearance of HBV. Here we report a case of severe hepatitis that manifested during chemotherapy in a female patient with chronic lymphocytic leukemia (CLL) who had been initially seronegative for HBsAg and seropositive for anti-HBs. The patient received chlorambucil and prednisolone for the treatment of CLL. After 6 months the serum levels of aminotransferases were increased, and HBsAg and HBV DNA were present in serum. Lamivudine was administered immediately after confirming the HBV reactivation, which considerably improved jaundice and aminotransferase levels after 3 weeks. The patient was able to resume the chemotherapy whilst continuing lamivudine treatment. This case report highlights the need for physicians to be aware of the potential risk of HBV reactivation even in an HBsAg-negative person but with detectable anti-HBc and/or anti-HBs, underscoring the need for future studies that explore the role of antiviral prophylaxis in this setting.

Palliative 5-fluorouracil and cisplatin chemotherapy in recurrent metastatic sebaceous carcinoma: Case report and literature review.

Sebaceous carcinoma is a rare malignant tumor of the skin. Although this tumor is not completely understood due to its rarity and the paucity of published reports, it is known to be an aggressive tumor with a high incidence in Asia. Sebaceous carcinomas occur preferentially in the periocular region and require attention not to miss the associated Muir-Torre syndrome. In the case of localized disease, a wide local excision with clear margin followed by adjuvant radiation therapy is usually considered the standard treatment strategy but there is no agreed treatment strategy or standard chemotherapeutic regimen for recurrent metastatic sebaceous carcinoma. We report here two cases of recurrent metastatic sebaceous carcinoma patients who responded to 5-fluorouracil and cisplatin combination chemotherapy, and review the literature. We suggest that 5-fluorouracil-cisplatin can be considered a feasible and effective treatment modality for recurrent sebaceous carcinoma.

A case of Primary Bone Anaplastic Large Cell Lymphoma.

BACKGROUND Anaplastic large cell lymphoma (ALCL) is a relatively rare subtype of non-Hodgkin's lymphoma (NHL). Like other types of NHL, ALCL primarily involves the nodal area, and sometimes it can involve several extra-nodal sites such as skin, soft tissue, and lungs. However, extensive bone involvement in cases of ALCL is very rare whether it is primary or secondary. Without nodular involvement, ALCL can be misdiagnosed as bone tumor or metastatic carcinoma such as lung, breast, or prostate cancer, which frequently spread to bone. CASE REPORT A 52-year-old woman with generalized pain and 2 months of fever of unknown origin presented to our institution. After extensive evaluation, only multiple osteolytic bone lesions with periosteal soft tissue reaction were identified. Repeated core needle biopsy revealed only inflammatory cells with histiocytic reactions. After pathologic and chromosomal analysis of sufficient tissue, which was acquired from incisional biopsy, primary bone ALCL was confirmed. CONCLUSIONS Clinicians should keep in mind that ALCL can present with extensive bone involvement without nodal involvement.

Clinical characteristics and outcomes in diffuse large B cell lymphoma patients aged 70 years and older: a single-center experience with a literature review.

BACKGROUND/AIMS: Among diffuse large B cell lymphoma (DLBCL) patients, determining the appropriate dose and chemotherapy schedule to balance toxicity and efficacy is harder in elderly than in younger patients. Moreover, there are no currently available clinical factors that consistently identify patients who are unfit to receive chemotherapy. Therefore, the clinical characteristics and outcomes of elderly patients with DLBCL and the causes of treatment-related death were investigated in this study. METHODS: The clinical characteristics and outcomes of 44 elderly (≥ 70 years of age) patients diagnosed with DLBCL between January 2005 and June 2013 were evaluated. Variable clinical data along with the response rate, overall survival (OS), and causes of treatment-related death or treatment interruption were investigated. RESULTS: The median OS was 18.6 months, and 19 patients completed curative treatment. The mean average relative dose intensity of adriamycin in patients who completed chemotherapy was 0.617, and of these patients, 16 achieved complete remission. Chemotherapy incompletion, infectious complications, ex tranoda l involvement, high lactate dehydrogenase, poor performance status, and low albumin level at diagnosis were related to a shorter OS. However, multivariate analysis revealed that only infections and chemotherapy incompletion were significantly related to poor prognosis. The most common cause of treatment-related death was infection, and patients who had experienced infectious complications tended to have lower albumin levels than those of patients without such complications. CONCLUSIONS: In the treatment of elderly lymphoma patients, the dose intensity of adriamycin is not as important as it is in young patients. However, in elderly patients, infections are particularly dangerous, especially in patients with low albumin levels.

Successful Treatment of Intracranial Germ Cell Tumor: Report of Two Unusual Cases and Literature Review.

Primary intracranial germ cell tumor (GCT) is a rare tumor that generally occurs due to developmental anomaly. Although intracranial GCT is sensitive to treatment, a high recurrence rate, treatment-related long-term complications and the heterogeneity of this tumor group make treatment complicated. Moreover, because of its location, hydrocephalus and visual field defect, functional disturbance of the pituitary gland can occur and require attention. Treatment primarily relies on chemotherapy and radiation therapy but the management of intracranial GCT remains unsettled, especially in the case of unusual circumstances such as multifocal tumor or nongerminomatous GCT. Here, we present two unusual cases of intracranial GCT: one case with a bifocal intracranial germinoma, and the other with an intracranial choriocarcinoma. Both cases were treated with neoadjuvant chemotherapy followed by reduced-field radiation therapy without significant treatment-related complication. Further, we performed a PubMed search to investigate the appropriate treatment strategy for this unusual subtype of intracranial GCT.

Cotransplantation of marrow stromal cells may prevent lethal graft-versus-host disease in major histocompatibility complex mismatched murine hematopoietic stem cell transplantation.

Marrow stromal cells (MSC) produce a microenvironment supporting hematopoiesis and may contribute immune tolerance because of low immunogenicity and the suppressive effect of alloreactivity. We investigated whether cotransplantation of MSC could prevent lethal graft-versus-host disease (GVHD) in major histocompatibility complex mismatched allogeneic murine hematopoietic stem cell transplantation (HSCT) using female BALB/c (H-2d, recipient) and C3H/He (H-2k, donor) mice. MSC were obtained from C3H/He bone marrow cells (BMC). MSC and irradiated BALB/c splenocytes (SP) were cocultured with C3H/He SP or BMC. Nonirradiated MSC did not inhibit the proliferation of alloantigen-stimulated BMC and SP. However, irradiated MSC suppressed the proliferation of alloantigen-stimulated SP at a level comparable with that of immunosuppressive agents, and the suppression by MSC was reversed to a significant degree by interleukin 2. Lethally irradiated BALB/c mice received transplants of donor cells according to the following experimental groups (group A, BMC only; group B, BMC and SP; group C, BMC, SP, and MSC; group D, BMC and MSC). The survival rate in group D was higher than in the other groups (P = .0057), and the clinical GVHD scores and serum levels of interferon-gamma were low in group D. Our results suggest that cotransplantation of MSC in HSCT prevents lethal GVHD, possibly by immune modulation.

Current status of therapeutic plasma exchange in Korea.

A nationwide survey on the status of plasma exchange in Korea was performed during the 2 year period 2001-02. Data from 496 patients were collected from 15 major hospitals. The most common indication was myasthenia gravis (15.3%), followed by thrombotic thrombocytopenic purpura (14.5%) and hemolytic uremic syndrome (9.7%). Clinical improvement was noted in 70.1% of the 415 cases. Plasma exchange by centrifugation alone accounted for 92.4%. Postcentrifugal filtration was carried out in 5.6% and double filtration in 2.0% of treatments. The most common instruments for the centrifugation were Cobe Spectra (71.3%) and Fenwal CS3000 (15.8%). Filtration was performed by either Kuraray KM8300 or Kuraray KM8800. The overall frequency of complications was 11.1% (293/2647 cases), of which symptomatic hypocalcemia was the most common (2.3%).

Complete Remission of Brain Metastases in Non-Small Cell Lung Cancer Patients Harboring an EGFR Mutation Treated with Tyrosine Kinase Inhibitor without Radiotherapy: A Report of 3 Cases.

Brain parenchymal metastasis from a solid tumor is a serious clinical condition associated with a poor outcome because systemic chemotherapy is usually ineffective for treating brain metastases (BM) due to the blood-brain barrier. Therefore, radiotherapy such as whole brain radiotherapy (WBRT) and stereotactic radiosurgery have taken on a central role in the management of BM. However, WBRT can delay subsequent systemic treatment or cause neurologic complications such as a decline in cognitive function. Therefore, suspending WBRT is worth considering if there is an effective alternative. Although there have been no large prospective studies, many reports are available about the favorable effect of tyrosine kinase inhibitors (TKIs) for treating BM in patients with non-small cell lung cancer (NSCLC). Here, we report 3 NSCLC cases that showed a complete response in BM after TKI treatment without WBRT. Based on these remarkable response rates of BM to a TKI, the potential toxicity of WBRT can be avoided, particularly in patients with small metastatic nodules and an epidermal growth factor receptor activating mutation.

A case of metastatic gastric neuroendocrine tumor: therapeutic considerations.

Despite remarkable progression in the treatment and classification system of neuroendocrine tumor (NET), some questions have remained unanswered. The lack of an established treatment strategy for gastric NET is one of the problems. Because of its paucity, gastric NET is not discussed in independent, large-scaled prospective studies and tends to be excluded from clinical trials. Moreover, a separate classification system and some distinguished clinical features render the treatment of gastric NET more complicated. Here, we present a case of a female gastric NET patient with G2 proliferation index and multiple liver metastases. Based on the histologic grade and a high serum gastrin level, we initially treated her with somatostatin analogue. However, the patient did not respond. After that, cytotoxic chemotherapy with the etoposide plus cisplatin regimen only showed response in the short-term period. However, combination therapy with octreotide and interferon brought about significant regression of the tumor. Herein, we present our case together with a literature review of the treatment of metastatic gastric NET.

Tumor lysis syndrome in a patient with metastatic colon cancer after treatment with 5-fluorouracil/leucovorin and oxaliplatin: case report and literature review.

Development of tumor lysis syndrome (TLS) may occur after chemotherapy or spontaneously in bulky or rapidly growing tumors. This syndrome is frequent but preventable in patients with hematologic malignancies. TLS following therapy has been reported infrequently in various types of solid tumors. TLS associated with oxaliplatin containing chemotherapy in a solid tumor has never been reported. A 59-year-old man received 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) chemotherapy for metastatic colon cancer. Development of TLS occurred three days after administration of chemotherapy. Two days later, his abnormal laboratory findings were recovered with appropriate management. To the best of our knowledge, the current case is the first report on development of acute TLS following oxaliplatin containing chemotherapy in a patient with colon cancer. We also review the literature on tumor lysis syndrome in patients with colorectal cancer.

Re-irradiation of unresectable recurrent head and neck cancer: using Helical Tomotherapy as image-guided intensity-modulated radiotherapy.

PURPOSE: Re-irradiation (re-RT) is considered a treatment option for inoperable locoregionally recurrent head and neck cancer (HNC) after prior radiotherapy. We evaluated the efficacy and safety of re-RT using Helical Tomotherapy as image-guided intensity-modulated radiotherapy in recurrent HNC. MATERIALS AND METHODS: Patients diagnosed with recurrent HNC and received re-RT were retrospectively reviewed. Primary endpoint was overall survival (OS) and secondary endpoints were locoregional control and toxicities. RESULTS: The median follow-up period of total 9 patients was 18.7 months (range, 4.1 to 76 months) and that of 3 alive patients was 49 months (range, 47 to 76 months). Median dose of first radiotherapy and re-RT was 64.8 and 47.5 Gy10. Median cumulative dose of the two courses of radiotherapy was 116.3 Gy10 (range, 91.8 to 128.9 Gy10) while the median interval between the two courses of radiation was 25 months (range, 4 to 137 months). The response rate after re-RT of the evaluated 8 patients was 75% (complete response, 4; partial response, 2). Median locoregional relapse-free survival after re-RT was 11.9 months (range, 3.4 to 75.1 months) and 5 patients eventually presented with treatment failure (in-field failure, 2; in- and out-field failure, 2; out-field failure, 1). Median OS of the 8 patients was 20.3 months (range, 4.1 to 75.1 months). One- and two-year OS rates were 62.5% and 50%, respectively. Grade 3 leucopenia developed in one patient as acute toxicity, and grade 2 osteonecrosis and trismus as chronic toxicity in another patient. CONCLUSION: Re-RT using Helical Tomotherapy for previously irradiated patients with unresectable locoregionally recurrent HNC may be a feasible treatment option with long-term survival and acceptable toxicities.

Long-term outcome of high-intensity focused ultrasound in advanced pancreatic cancer.

OBJECTIVES: The aim of this study was to evaluate safety and efficacy of high-intensity focused ultrasound (HIFU) for advanced pancreatic cancer (PC). METHODS: Patients with PC TNM stage III or IV were included. Magnetic resonance imaging was performed 2 weeks before and after the HIFU. The ablating tumor volume was calculated by ratio of the nonperfused necrotic area of the planned area on contrast-enhanced T1-weighted image on post-HIFU magnetic resonance imaging. The ablation results were stratified into 4 ranges: 100% to 90% unenhanced area of targeting area, 90% to 50%, within 50%, and no change. RESULTS: High-intensity focused ultrasound treatment was performed without severe adverse event in 46 patients, 49 times (male-female = 25:21; mean age, 60.7 ± 10.0; TNM stage 3-stage 4 = 18:28). Average size of the PC lesion was 4.2 ± 1.4 cm (1.6-9.3 cm). After HIFU treatment, ablating tumor volume was as follows: 90% to 100% in 38 lesions, 90% to 50% in 8, and within 50% in 3. Overall median survival (S1) from initial PC diagnosis was 12.4 months. Overall survival (S2) rates at 6, 12, and 18 months from HIFU were 52.2%, 30.4%, and 21.79%, respectively, with a median survival of 7.0 months CONCLUSIONS: High-intensity focused ultrasound is safe and effective, which induced excellent local tumor control in most patients with advanced PC.

Helical tomotherapy with concurrent capecitabine for the treatment of inoperable pancreatic cancer.

BACKGROUND: Helical tomotherapy, an advanced intensity-modulated radiation therapy with integrated CT imaging, permits highly conformal irradiation with sparing of normal tissue. Capecitabine, a pro-drug of 5-FU that induces thymidine phosphorylase can achieve higher levels of intracellular 5-FU when administered concurrently with radiation. We evaluated the feasibility as well as the clinical outcome of concurrent administration of capecitabine with tomotherapy in patients with advanced pancreatic cancer. METHODS: Nineteen patients with advanced pancreatic cancer including primarily unresectable disease and recurrence after curative surgery were included in the study. Two planning target volumes (PTV) were entered: PTV1 is gross tumor volume; and PTV2, the volume of the draining lymph nodes. The total doses to target 1 and target 2 were 55 and 50 Gy, respectively. Capecitabine at 1600 mg/m2/day was administered on each day of irradiation. RESULTS: Twenty six measurable lesions were evaluated. Overall in-field response rate was 42.3%; partial responses were achieved in 53.3% of the pancreatic masses, 28.6% of distant metastatic lesions and 25.0% of regional lymph nodes. The median duration of follow-up after tomotherapy was 6.5 months. None of the lesions showed in-field progression. Treatment was well tolerated with only minor toxicities such as grade 1 nausea (one patient), grade 1 hand-foot syndrome (one patient) and grade 1/2 fatigue (three patients). CONCLUSIONS: Helical tomotherapy with concurrent capecitabine is a feasible option without significant toxicities in patients with advanced pancreatic cancer. We achieved excellent conformal distribution of radiation doses and minimal treatment-related toxicities with promising target volume responses.
