RESUMO

Purpose@#Currently, trastuzumab plus chemotherapy is the standard first-line therapy for human epidermal growth factor receptor 2 (HER2)-positive advanced or metastatic gastric cancer (mGC) or esophagogastric junction cancer. However, it is not clear whether the prognosis of HER2-positive mGC treated with trastuzumab plus chemotherapy is better than that of HER2-negative mGC treated with chemotherapy as the first-line therapy. @*Methods@#We performed a retrospective study comparing the prognosis of mGC according to first-line treatment with trastuzumab plus chemotherapy or chemotherapy only, at the Korea Cancer Center Hospital from 2011 to 2018. The Kaplan-Meier method and Cox proportional hazards model were used for univariate and multivariate survival analyses. @*Results@#The median overall survival of trastuzumab group was 26.1 months and that of chemotherapy group was 14.8 months (P=0.047). Trastuzumab group had a longer median progression-free survival than chemotherapy group (23.4 vs. 9.2 months, P=0.026). By univariate analysis, sex, age, World Health Organization (WHO) histology, HER2 status, primary tumor site, extent of disease, number of lesions, number of metastatic, measurability of disease, prior gastrectomy, and chemotherapy group are statistically significant. Using multivariate analysis, number of lesions, number of metastatic, prior gastrectomy, and trastuzumab group (hazard ratio, 0.594; 95% confidence interval, 0.384–0.921; P=0.020) were found to be independent prognostic factors of overall survival. @*Conclusion@#The result suggests prognosis of HER2-positive mGC treated by trastuzumab plus chemotherapy could be better than that of HER2-negative mGC treated by chemotherapy only. Well-designed prospective cohort studies are needed to confirm the results of this study. HER2 testing should be performed routinely in all patients newly diagnosed with mGC.

RESUMO

PURPOSE: This study was conducted to evaluate the efficacy and safety of azasetron compared to ondansetron in the prevention of delayed chemotherapy-induced nausea and vomiting. MATERIALS AND METHODS: This study was a multi-center, prospective, randomized, double-dummy, double-blind and parallel-group trial involving 12 institutions in Korea between May 2005 and December 2005. A total of 265 patients with moderately and highly emetogenic chemotherapy were included and randomly assigned to either the azasetron or ondansetron group. All patients received azasetron (10 mg intravenously) and dexamethasone (20 mg intravenously) on day 1 and dexamethasone (4 mg orally every 12 hours) on days 2-4. The azasetron group received azasetron (10 mg orally) with placebo of ondansetron (orally every 12 hours), and the ondansetron group received ondansetron (8 mg orally every 12 hours) with placebo of azasetron (orally) on days 2-6. RESULTS: Over days 2-6, the effective ratio of complete response in the azasetron and ondansetron groups was 45% and 54.5%, respectively (95% confidence interval, -21.4 to 2.5%). Thus, the non-inferiority of azasetron compared with ondansetron in delayed chemotherapy-induced nausea and vomiting was not proven in the present study. All treatments were well tolerated and no unexpected drug-related adverse events were reported. The most common adverse events related to the treatment were constipation and hiccups, and there were no differences in the overall incidence of adverse events. CONCLUSION: In the present study, azasetron showed inferiority in the control of delayed chemotherapy-induced nausea and vomiting compared with ondansetron whereas safety profiles were similar between the two groups.

RESUMO

Alpha-thalassemia (alpha-thalassemia), which is prevalent in the Mediterranean region, is caused by deficient synthesis of the alpha-globin chains. It is commonly caused by HBA1 and/or HBA2 gene deletion and is diagnosed by DNA sequence analysis. The proband was a 38-year-old woman who was found to have microcytic and hypochromic anemia on a routine health checkup. Results of the Hb electrophoresis (EP) and direct sequencing of the HBA1 and HBA2 genes were found to be normal. As multiplex ligation-dependent probe amplification (MLPA) for the HBA1 and HBA2 genes revealed heterozygous deletion, she was diagnosed with heterozygous alpha+-thalassemia. Although routine laboratory tests revealed similar findings in the proband's father, brother and niece, MLPA revealed heterozygous deletions of the HBA1 or HBA2 gene in her brother and niece. In summary, we report a case of heterozygous alpha+-thalassemia in a Korean family that was detected by MLPA. We recommend that patients with suspected hemoglobinopathies should be followed-up further with MLPA, especially when Hb EP shows a normal pattern.

RESUMO

BACKGROUND: This study evaluates the effectiveness of immunochemotherapy and radiation therapy in the treatment of patients with primary bone lymphoma (PBL). METHODS: We retrospectively reviewed the medical records of 33 patients with PBL who were treated at 6 medical centers in Korea from 1992 to 2010. Clinicopathological features and treatment outcomes were analyzed. RESULTS: The median age of the patients participating in our study was 40 years. The most common sites of involvement were the pelvis (12.36%) and femur (11.33%). CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) or CHOP-like regimens were administered to 20 patients (61%), and R-CHOP (rituximab plus CHOP) was administered to the remaining 13 patients (39%). The overall response rate was 89% (complete response, 76%; partial response, 12%). The overall survival (OS) of patients with solitary bone lesions was longer than that of patients with multiple bone lesions (median OS: not reached vs. 166 months, respectively; P=0.089). Addition of rituximab to CHOP did not significantly affect either OS or progression-free survival (P=0.53 and P=0.23, respectively). Combining radiation therapy with chemotherapy also did not improve the OS or progression-free survival of patients with solitary bone lesions. CONCLUSION: Conventional cytotoxic chemotherapy remains an effective treatment option for patients with PBL. Additional benefits of supplementing chemotherapy with either rituximab or radiation therapy were not observed in this study. Further investigation is needed to characterize the role of immunochemotherapy in treating patients with PBL.

RESUMO

Myeloid neoplasm with the platelet-derived growth factor receptor beta (PDGFRB) rearrangement is a myeloproliferative neoplasm. Patients with this disease often have prominent eosinophilia or monocytosis and the presence of t(5;12)(q31~33;p12) or a variant translocation with expression of an ETV6-PDGFRB fusion gene or the PDGFRB rearrangement. We report an 82-year-old woman with a myeloid neoplasm, with the PDGFRB rearrangement, who presented with a dry cough, eosinophilia and thrombocytosis. The chromosome study of the bone marrow showed 46,XX,ins(1;5)(q22;q33q13.3), and fluorescence in situ hybridization (FISH) analysis revealed rearrangement of the PDGFRB gene. The patient was successfully treated with low-dose imatinib.

RESUMO

The purpose of our study was to determine the most accurate analytic method to define in vitro chemosensitivity, using clinical response as reference standard in prospective clinical trial, and to assess accuracy of adenosine triphosphate-based chemotherapy response assay (ATP-CRA). Forty-eight patients with chemo-naive, histologically confirmed, locally advanced or metastatic gastric cancer were enrolled for the study and were treated with combination chemotherapy of paclitaxel 175 mg/m2 and cisplatin 75 mg/m2 for maximum of six cycles after obtaining specimen for ATP-CRA. We performed the receiver operator characteristic curve analysis using patient responses by WHO criteria and ATP-CRA results to define the method with the highest accuracy. Median progression free survival was 4.2 months (95% confidence interval [CI]: 3.4-5.0) and median overall survival was 11.8 months (95% CI: 9.7-13.8) for all enrolled patients. Chemosensitivity index method yielded highest accuracy of 77.8% by ROC curve analysis, and the specificity, sensitivity, positive and negative predictive values were 95.7%, 46.2%, 85.7%, and 75.9%. In vitro chemosensitive group showed higher response rate (85.7% vs. 24.1%) (P=0.005) compared to chemoresistant group. ATP-CRA could predict clinical response to paclitaxel and cisplatin chemotherapy with high accuracy in advanced gastric cancer patients. Our study supports the use of ATP-CRA in further validation studies.

RESUMO

Angioimmunoblastic T-cell lymphoma (AITL) is a systemic lymphoproliferative disorder that presents with profound immune dysfunction and immunodeficiency. As in many other immunodeficiencies, Epstein-Barr virus (EBV) associated B-cell lymphoid proliferation can occur in AITL but few cases of EBV-positive B-cell lymphoma have been reported in patients with preexisting AITL. We report a case of AITL in which EBV-positive diffuse large B-cell lymphoma (DLBCL) developed 13 months after the initial diagnosis of AITL. Although the exact mechanisms remain unclear, Epstein-Barr virus may have played a role in the pathogenesis of the secondary DLBCL

RESUMO

Primary gastric choriocarcinoma (PGC) is a rare tumor, and its pathogenesis is still uncertain. Most PGCs have been reported to possess an adenocarcinoma component of variable extent, and pure PGC is especially rare. The diagnosis of PGC is confirmed by exhibition of choriocarcinomatous components on biopsy and exhibition of beta-hCG positive cell on immunohistochemical stain and elevation of the serum beta-hCG. Moreover it must be confirmed that no other site including gonads displays any tumor masses. The PGC tends to be more invasive and to have early metastasis. The median survival is known to be less than several months. We report two cases. The first case was a 62 year-old man who was diagnosed as advanced gastric cancer (AGC) by endoscopic biopsy with hepatic metasasis and received palliative chemotherapy with modified FOLFOX regimen and Genexol plus cisplatin regimen. He underwent subtotal gastrectomy due to perforation of the stomach during chemotherapy. On post-operative biopsy, He wasre-diagnosed as PGC and received another palliative chemotherapy modified FOLFIRI, BEP, EMACO, VIP. However, multiple liver metastases were aggravated, and also serum AFP level increased. Ultimately, the paient died 10 months after initial diagnosis. Another case was a 45 year-old man. On endoscopic biopsy, he was diagnosed as AGC of adenocarcinoma. On Chest and Abdomen CT, multiple pulmonary and hepatic metastasis were also confirmed. On liver biopsy, He was diagnosed as PGC. The immunohistochemical stains were performed and the results were cytokeratin positive, EMA negative and beta-hCG weak positive. The serum beta-hCG level was highly elevated. BEP, VIP and EMA/CO combination therapy were administered, but he died at 12th months after the initial diagnosis.

RESUMO

Extraskeletal Ewing's sarcoma is rarely found in the head and neck regions. We report an unusual case of extraskeletal Ewing's Sarcoma of the parapharynx region in a 49-year-old man who presented with blindness. MRI examination showed marked enhancement of tumor thrombosis involving the superior sagittal sinus, straight sinus, transverse sinus, sigmoid sinus, and internal jugular vein. The final diagnosis was extraskeletal Ewing's sarcoma after biopsy of the internal jugular vein thrombosis by histopathological evaluation and immunohistochemical assay. In addition, the patient was diagnosed as having adenocarcinoma of the rectum by biopsy of the rectal mass. The patient was treated with systemic chemotherapy and showed improved response with durable remission. The patient's visual acuity, however, did not improve.

RESUMO

The aim of the current study was to determine the clinical significance according to the subtypes of epidermal growth factor receptor (EGFR) mutations and presence of KRAS mutations in operable non-small-cell lung cancer (NSCLC). We sequenced exons 18-21 of the EGFR tyrosine kinase domain and examined mutations in codons 12 and 13 of KRAS in tissues of patients with NSCLC who had undergone surgical resection. EGFR mutations were more frequent in never-smokers than smokers (33% vs. 14%, respectively; p=0.009) and in females than in males (31% vs. 16%, respectively; p=0.036). Mutations in exon 18-19 and 20-21 were found in 10 and 22 patients, respectively. Never-smokers and broncho-alveolar cell carcinoma features were positively associated with a mutation in exon 18-19 (p=0.027 and 0.016, respectively). The five-year survival rate in patients with a mutation in exons 18-19 (100%) was higher than that in patients without such mutation (47%; p=0.021). KRAS mutations were found in 16 patients (12%) and were not related to the overall survival (p=0.742). Patients with an EGFR mutation in exons 18-19 had better survival than patients without such mutation. Subtypes of EGFR mutations may be prognostic factors in patients undergoing curative resection.

RESUMO

Hypereosinophilic syndrome (HES) is a clinical disorder characterized by persistent eosinophilia and systemic involvement, in which a specific causative factor for the eosinophilia cannot be verified during a certain period of time. There have been only a few reported cases of this syndrome associated with malignant lymphoma. We report a case of peripheral T-cell lymphoma-unspecified with hypereosinophilic syndrome. The patient was a 42-year-old woman with an uncontrolled fever and a sore throat. Eosinophilia was observed on the peripheral blood smear. We confirmed the diagnosis by bone marrow and liver biopsies: A bone marrow aspiration demonstrated markedly increased eosinophils (24.8%), and a liver biopsy demonstrated infiltration by scattered eosinophils and atypical lymphoid cells, which were confirmed to be T-cell lymphoma cells. This case was a distinctive presentation of peripheral T-cell lymphoma with hypereosinophilic syndrome, probably due to a paraneoplastic condition.

RESUMO

Small cell lung cancer (SCLC) is one of the most fatal cancers in humans and many factors are known to be related to its poor prognosis. Immunohistochemical (IHC) stainings were done on SCLC specimens in order to investigate the prognostic value of the apoptosis-related gene expression and the tumor proliferative maker, and the relationships among these IHC results and patients clinical characteristics, chemoresponsiveness, and survival were analyzed. The medical records of 107 patients were reviewed retrospectively. IHC stainings for p53, bcl-2 and Ki-67 expressions were performed in the 66 paraffin-embedded biopsy samples. Sixty-six out of the 107 patients were evaluable for response rate and survival. The overall response rate was 75% (95% Confidence Interval=74-76%) and the median survival time was 14 months. The median survival time of limited stage was 16 months and that of extensive stage was 10 months. The prevalence of p53, bcl-2 and Ki-67 expression was 62%, 70%, and 49%, respectively. There were no correlations among the immunoreactivities of p53, bcl-2 and Ki-67 with clinical stage, chemoresponsiveness or overall survival. The clinical stage was the only prognostic factor influencing survival. The expression rates of p53, bcl-2, and Ki-67 were relatively high in SCLC without any prognostic significance. The exact clinical role of these markers should be defined through further investigations.

RESUMO

The potential therapeutic benefit of introducing IFN-gamma and GM-CSF genes in combination with the HSVtk suicide gene into subcutaneously implanted CT26 tumor cells was compared with that from each treatment alone. Cells, unmodified or retrovirally transduced with HSVtk or IFN-gamma/GM-CSF genes, were inoculated subcutaneously into syngeneic BALB/c mice in various combinations. HSVtk gene, with intraperitoneal ganciclovir treatment, reduced tumor volume by 81% at locally inoculated tumor sites (p<0.01) and by 25% at distantly inoculated tumor sites (p=0.052). IFN-gamma/GM-CSF genes showed a 56% tumor volume reduction at local tumor sites (p<0.01) and 15% volume reduction at remote tumor sites, although this was not statistically significant. The combination of HSVtk (with GCV) and IFN-gamma/GM-CSF genes showed an 81% volume reduction at local tumor sites (p<0.01) and a 43% volume reduction at remote tumor sites (p<0.01). Thus, the combination of HSVtk and IFN-gamma/GM-CSF gene therapy produced greater therapeutic efficacy than either treatment alone.

RESUMO

Granulocytosis occurs in 40% of patients with lung and gastrointestinal cancers, 20% of patients with breast cancer, 30% of patients with brain tumor and ovarian cancer and 10% of patients with renal cell carcinoma. Granulocytosis occurs because of production of G-CSF, GM-CSF and IL-6. Uterine cervical carcinoma with granulocytosis as a paraneoplastic syndrome, however, has been rarely reported. We recently witnessed a case of invasive squamous cell carcinoma of the uterine cervix with granulocytosis. Leukocytosis developed up to 69, 000/micro L, and then normalized after chemo-radiotherapy. There was no evidence of infection, tumor necrosis, glucocorticoid administration, or myeloproliferative disease by examination of a bone marrow aspirate when granulocytosis appeared. This phenomenon was probably associated with the secretion of hematopoietic growth factors such as G-CSF, GM-CSF and IL-6 by the tumor. We suggest that, like some other solid tumors, cervical cancer can present with granulocytosis as a paraneoplastic syndrome.

RESUMO

BACKGROUND: The outcome of hematopoietic stem cell transplantation (HSCT) for patients with severe aplastic anemia (SAA) in Seoul National University Hospital was analyzed retrospectively. METHODS: Between January, 1990 and March, 1999, 25 patients with SAA underwent HSCT. Their medical records were reviewed. Statistical analyses were done about survival and complication after HSCT. RESULTS: The median age of patients was 22 (range, 14~43) and male to female ratio was 18 : 7. Twenty two were HLA matched non- identical siblings. Three were one identical twin, one one-locus mismatched father and one HLA matched unrelated donor, respectively. Conditioning regimens were CY/TLI (cyclophosphamide, total lymphoid irradiation) for 18 patients, CY/ATG (CY, antithymocyte globulin) for 3, CY/ buffy (CY, unirradiated buffy- coat) for 2, CY/ ATG/TLI for 1, BU/CY (busulfan, CY) for 1. For prophylaxis of graft-versus-host disease (GVHD), cyclosporine and methotrexate were used in all patients except for identical twin. The median nucleated cell dose given to patients was 4.5x108/kg (range, 2.0~5.9). All evaluable patients achieved absolute neutrophil count of 500/microliter after median 17 days of HSCT (range, 12~27) and untransfused platelet count over 20,000/microliter after median 21 days of HSCT (range, 13~67). Six patients (24%, grade I : 3, II : 1, III : 1, IV : 1) developed acute GVHD and 8 (32%, limited : 4, extensive : 4) developed chronic GVHD. Hepatic venoocclusive disease (VOD) occurred in 2 patients (8%). Rejection occured in 4 patients (16 %), but among 22 allogeneic transplant recipients from HLA matched siblings, only one (5%) lost graft. After a median follow-up of 32 months (range 9~120 months), 5 year overall survival of all patients was 87%, and that of 22 allogeneic recipients from HLA matched sibling donors was 95%. Four patients (16%) died. Causes of death were VOD in one case, rejection with pneumonia one, acute GVHD one. One died from traffic accident in a cured state. CONCLUSION: Experiences from our center suggest that HSCT is an effective treatment for patients with severe aplastic anemia. Long- term survival is especially excellent for patients who have matched related donors.

RESUMO

BACKGROUND: Acute myelogenous leukemia (AML) is the most common cause of leukemia in adults. Allogeneic bone marrow transplantation (BMT) for the treatment of AML is done worldwide now. METHODS: Between November 1987 and June 1998, we performed allogeneic BMT for 27 patients with AML from HLA-identical sibling donors. We reviewed medical records of these patients. RESULTS: The median age of patients was 31 (range, 15~43) and male to female ratio was 18 : 9. Conditioning regimens were BU/CY (busulfan, cyclophosphamide) for 22 patients, TBI/CY (total body irradiation, cyclophosphamide) for 3 patients, and TBI/VP/CY (TBI, VP-16, cyclophosphamide) for 2 patients. Cyclosporine and methotrexate were used in 18 patients for prophylaxis of graft-versus-host disease (GVHD), and cyclosporine and methyl-prednisolone were used in 9 patients. The median nucleated cell dose given to patients was 4.1x108 /kg. All evaluable patients achieved absolute neutrophil count of 500 /microliter after median 15 days after BMT (range, 11~45 days). Twenty-five percent of patients developed acute GVHD (> or = grade II) and there was no patient with grade IV acute GVHD. Twenty-nine percent developed chronic GVHD. Hepatic venoocclusive disease (VOD) occurred in 7 patients (26%). At the time of BMT, 16 patients were in the first remission status and 11 patients were in the advanced disease status. After a median follow-up of 27 months (range 7~127 months), the actuarial disease-free survival at 5 years was significantly higher in the first remission group than the others (44% vs. 9%; P=0.05). The difference of 5 year overall survival between these two groups approached statistical significance (50%for the first remission group and 12% for the others; P=0.13). There were 17 deaths. The causes of death were relapse (8 patients, 47%), VOD (3 patients, 18%), sepsis (2 patients, 12%), interstitial pneumonia (2 patients, 12%), chronic GVHD (1 patient, 6%), and drug-toxicity (1 patient, 6%). Eary deaths (<100 days) occurred in 6 patients (22%). CONCLUSION: Allogeneic BMT for patients with AML was most successful when done during the first remission. Clinical features of patients with AML treated with allogeneic BMT were similar to those from Western countries, but the incidence and severity of acute GVHD seem to be lower.

RESUMO

Although the outcome and the possibility of renal recurrence of disease in systemic lupus erythematosus is still a matter of controversy, kidney transplantation is generally regarded as a proper indication for the treatment of patients with end stage renal failure caused by systemic lupus erythematosus. Hemolytic uremic syndrome is characterized by the symptoms of sudden onset of hemolytic anemia, thrombocytopenia, and deteriorating renal function. Many patients with postrenal transplantation hemolytic uremic syndrome have lost their grafts because of no known established treatment modality. Although the substitution of cyclosporine to FK506 is reported as a successful strategy for the treatment of cyclosporine associated hemolytic uremic syndrome in many reported cases, we cannot find the constant reports because FK506 or even OKT3 is also known as the cause of postrenal transplantation hemolytic uremic syndrome. But cyclosporine associated hemolytic uremic syndrome can be treated by the proper choice of immunosuppressant and conservative treatment. In this report, a patient with end stage renal failure caused by systemic lupus erythematosus experienced cyclosporine associated postrenal transplantation hemolytic uremic syndrome. He has recovered from the symptoms by withdrawal of cyclosporine and reduced dose of FK506 and at the same time, conservative treatment. We report this case with literature review.

RESUMO

Pernicious anemia is understood as an autoimmune disease and associated with various other autoimmune diseases, such as Graves` disease, primary hypothyroidism, thyroiditis and vitiligo. We report a case of pernicious anemia associated with autoimmune thyroiditis. A 40-year-old man was admitted to the Sanggye Paik Hospital due to general weakness, dyspnea on exertion and sore throat for 2 months. Eight years before admission, he had been treated with hyperthyroidism in other hospital. Examination revealed anemic conjunctivae, exophthalmos and smooth and beefy tongue. Laboratory tests showed 6.2g/dL of hemoglobin, 16.7% of hematocrit, 7,970/microliter of WBC, 152,000/microliter of platelets and 116.3fL of MCV. Reticulocyte index was 0.3%. Peripheral blood smear showed macrocytic red blood cells and hypersegmented neutrophils. The level of vitamin B12 was 139.2pg/mL and folic acid was in normal range. The result of schilling test was abnormal. Anti-parietal cell antibody was positive. The results of thyroid function tests were compatible with hypothyroidism and anti-microsomal antibody was positive. TBII was 9.8U/L. Treatment with vitamin B12 and thyroid hormone was started. Three months after treatment, he has been completely free of symptoms. Now he has been treated with thyroxine 0.2mg per day and adenosylcobalamine 1,000microgram per 2 month.
