1.A Paradigm Shift: Perioperative Iron and Erythropoietin Therapy for Patient Blood Management.
Hanyang Medical Reviews 2018;38(1):16-26
Allogeneic blood transfusion is often restricted due to its adverse effects, a lack of blood supply, and religious or cultural constraints. As a result, patient blood management (PBM) has been gaining attention. PBM is an evidence-based, patient-centered bundle of technologies that manages perioperative anemia and reduces bleeding during surgery. PBM improves the postoperative prognoses. Perioperative anemia is the main concern in PBM; therefore, to diagnose and treat it is important. This review focuses on the perioperative use of oral or intravenous iron and erythropoietin (EPO), in relevant fields such as cardiac surgery, orthopedics, and neurosurgery. IV administration of iron has been controversial due to safety concerns, such as increased risk of infection. However, using IV iron appropriately is beneficial in most surgical settings. Although recombinant human EPO may increase thromboembolic risks, this can be mitigated through various methods including limiting the target Hb level, using it in combination with IV iron, or prophylaxis for deep venous thrombosis. EPO is recommended in patients undergoing cardiac or orthopedic surgery. As PBM becomes globally implemented, the blood management methods, including tranexamic acid, hemostatic agents, and cell salvage have become more variable as well. Among them, administration of iron and EPO would be the most common pharmacologic choices based on current practice. However, controversy still exists. Therefore, further studies on iron and EPO are needed to ensure better and safer patient care.

2.actate Dehydrogenase (LDH) as a Tumor Marker for Non-small Cell Lung Cancer.
Cancer Research and Treatment 2002;34(5):339-344
PURPOSE: To determine the prognostic value of pre- treatment serum LDH levels and the LDH isoenzyme pattern for non-small cell lung cancer, and to determine the relationship between the response to chemotherapy and the changes in serum LDH levels following chemotherapy MATERIALS AND METHODS: Patients with pathologically confirmed non-small cell lung cancer were entered onto this study. Their serum LDH levels were assessed prior to chemotherapy, with the LDH isoenzyme being assessed in patients with high initial serum LDH levels. The serum LDH levels were re-assessed following 2 cycles of chemotherapy. The relationship between the response to chemotherapy, pre-treatment serum LDH levels and LDH isoenzyme pattern and the changes in serum LDH levels, following chemotherapy, were evaluated. RESULTS: 49 patients were entered onto this study. The pre-treatment serum LDH levels were normal in 26 patients, and elevated in 23. The LDH isoenzyme was evaluated in 15 patients, with LDH2 being elevated the most frequently. The response rate to chemotherapy was 42.9% in all 42 patients able to be evaluated, 45.8% in patients with normal serum LDH levels and 41.2% in patients with elevated serum LDH levels. This difference was not statistically significant (p=0.767). The median survival was 37 weeks in all patients able to be evaluated, 38 weeks in those with normal serum LDH levels and 31 weeks in those with elevated serum LDH levels. These differences were not statistically significant (p=0.202). The patients with normal serum LDH levels following chemotherapy were more responsive to chemotherapy than those with elevated serum LDH levels following chemotherapy (response rate 51.4% vs. 0%, p=0.027). CONCLUSION: The LDH2 are most commonly elevated in non small cell lung cancer patients. The pre-treatment serum LDH levels do not reflect the prognosis accurately. The serum LDH levels following chemotherapy are associated with the response to chemotherapy.

Korean Journal of Hematology 2004;39(2):103-108
BACKGROUND: Automated counting of reticulocyte introduced new reticulocyte parameters such as immature reticulocyte fraction (IRF). IRF is thought to be more sensitive than absolute or corrected reticulocyte count for detecting recovery of bone marrow function. The aim of this study is to assess the role of IRF for predicting the response of therapy after treatment of iron deficiency anemia. METHODS: Patients with previously untreated iron deficiency anemia (blood hemoglobin <10.0g/dL and serum ferritin <10ng/mL) were enrolled into this study. On the 8th day of iron therapy, Complete blood count (CBC) with reticulocyte count and IRF was assessed by RAM-1 reticulocyte autoanalyzer (Sysmex. Tokyo, Japan). IRF was defined as sum of the reticulocyte fraction of high-fluorescence intensity regions plus the fraction of middle fluorescence intensity regions. After 1 month of iron therapy, CBC was reassessed to evaluate the response of iron therapy. The correlation of the 8th day IRF and the change of hemoglobin level after 4 weeks of therapy was evaluated. The 8th day corrected reticulcyte count was also evaluated. RESULTS: From Jan. 2001 to May 2003, 27 patients with iron deficiency anemia (3 men and 24 women) entered into this study. We evaluated 21 patients, excluding 6 patients who were lost to follow-up or refused blood sampling after 1 month of iron therapy. The range of pretreatment hemoglobin level was 3.3-9.7g/dL (median 7.5g/dL). The 8th day IRF was 0.06-0.39 (median 0.15). Ten patients had the low IRF (IRF < or = 0.15). Four of them (40%) had their hemoglobin level increased by more than 3g/dL. On the other side, 11 patients had high IRF (IRF>0.15) and 10 of them (91%) had their hemoglobin level increased by more than 3g/dL. This difference was significant (P=0.024). However, the 8th day IRF was not correlated with the change of hemoglobin as strongly as the 8th day corrected reticulocyte count (Pearson coefficient 0.420 vs 0.693). CONCLUSION: For the patients with iron deficiency anemia, the 8th day of treatment IRF correlates with the response of iron treatment, but the 8th day of treatment corrected reticulocyte count has a stronger correlation.

BACKGROUND: Most patients with gastric cancer have metastatic disease at first diagnosis and need palliative chemotherapy. Unfortunately, the response duration of the first line chemotherapy is usually short and most patients need the second line therapy during their disease process. The action mechanism of continuous infusion of 5-FU is different from bolus 5-FU and we can expect that among patients who failed on bolus 5-FU, some patients will achieve response to infusional 5-FU. So, we planned to evaluate the efficacy and safety of leucovorin and infusional 5-FU as a second line regimen for the metastatic gastric cancer refractory to regimen containing bolus 5-FU. METHODS: Patients with recurred or metastatic gastric cancer unresponsive to regimen containing bolus 5-FU were entered into this study. The mixture of 5-FU 1,000 mg/m2/day and leucovorin 50 mg/m2/day was infused continuously for four days and this treatment was repeated by every three weeks. RESULTS: From March, 1996 to July 2001, 25 patients were enrolled in this study. One patient showed a partial remission, 9 stable disease and 15 progressive disease. The overall response rate was 4%. The median time to progression was 73 days and the median duration of overall survival was 140 days. Among total of 92 cycle chemotherapy, leukopenia, granulocytopenia and thrombocytopena of WHO grade 3 or 4 were observed in 7.6%, 12.0% and 14.1%, respectively. Stomatitis, nausea or vomiting of WHO grade 3 or 4 were 13.1%, 5.4%, respectively. Neutropenic infection occurred in two patients. CONCLUSION: The LF regimen was well tolerated with minimal toxicities and showed low effect as the second line chemotherapy for the patients with gastric cancer.

BACKGROUND: The objective responses of cisplatin and etoposide (PVP) combination chemotherapy as second-line therapy following CAV was high (40~50%) and, in several reports, PVP yields survival results that are at least as good as those obtained with cyclophosphamide or doxorubicin-based regimens and with less host-related toxicity in chemotherapy-naive patients. We conducted a phase II study to evaluate the effect of a combination of cisplatin and etoposide as a first-line therapy in patients with small cell lung cancer. METHODS: Sixty-one previously untreated small cell lung cancer patients with measurable lesion(s) received cisplatin(30 mg/m2 IV, day 1~3) and etoposide(100 mg/m2 IV, day 1~3). In patients with limited disease, after completion of 6 cycles of PVP chemotherapy, chest and prophylatic brain irradiation was performed in case of complete responder, chest irradiation only in partial responder. RESULTS: 1) Of 55 evaluable patients, 13(24%) had a complete response and 29(53%) had a partial response. 2) The median survival time was 55.8 weeks for all patients(N=55), 61.1 weeks for limited disease(N=31), 51.3 weeks for extensive disease(N=24). 3) The response duration was 29.1 weeks for responders(N=42). 4) There was no significant prognostic factors iufluencing response rates. 5) The toxicity was tolerable and there was no treatment-related deaths. CONCLUSION: The PVP combination chemotherapy as a first-line therapy was effective and well-tolerated in patients with small cell lung cancer.

The damage which radiation produces in tissues such as the lungs can be discussed at the molecular, biophysical, cellular, and organ levels. The cellular effects of irradiating the lungs are related to the histologic and clinical sequelae. In the present study the right lung of rabbits were exposed to single dose of 20 Gy of X-irradiation. Animals from each group were sacrificed monthly for 6 months postexposure. Sections of lung were examined by light microscopy(LM) and by transmission electron microscopy(TEM). Multiple exudative lesions were seen at 2 months after the 20Gy irradiation, and they progressed to a proliferative and then reparative fibrotic lesion by 6 months. Changes in epithelial lining of lung components, particulary the presence of type II pneumocytes were found by both LM and TEM. Capillary endothelial damages were less pronounced. The possible implication of cellular components in radiation pneumonitis and fibrosis is discussed.

BACKGROUDN: Small cell lung cancer (SCLC) is a chemotherapy-sensitive tumor. However, the duration of response is usually short and most patients experience relapses. Topotecan is commonly used for treatment of these patients. Nevertheless, the response rate of topotecan as a single regimen is only about 20% and the resulting severe myelosuppression is troublesome. Vincristine is also an active agent, and it does not compromise the marrow function. In this background, we evaluated the efficacy and toxicities of topotecan and vincristine combination chemotherapy. METHODS: Patients with pathologically confirmed SCLC refractory to or recurrent after platinum-based chemotherapy were eligible for this study. The treatment regimen was as follows; topotecan 1.5 mg/m2/day IV bolus on day 1, 2 and 3 and vincristine 1.5 mg/m2 (maximum 2 mg on day 1 (on every cycle)) and day 2 (on odd cycles only). This regimen was repeated every 3 weeks. The efficacy was evaluated in terms of response rate, time to progression and overall survival duration. The toxicities were assessed according to NCI-CTC version 3.0. RESULTS: A total of 19 patients were entered into this study. The median age was 63 years (range 43-85 years). Partial response was obtained for 3 patients (response rate 15.8%, 95% CI: 0-32.5%). The median time to progression and survival duration was 51 days and 199 days, respectively. For a total of 52 cycles of treatment, grade 3 or 4 neutropenia and thrombocytopenia were observed in 25.0% and 11.5% of the patients, respectively. Grade 2 neurotoxicities were observed in 15.4% of the patients. There was no treatment-related mortality. CONCLUSIONS: The topotecan and vincritine combination is active and safe for patients with recurrence or refractory SCLC. However, the benefit of adding vincristine to topotecan needs to be confirmed in further studies.

Cancer Research and Treatment 2008;40(3):116-120
PURPOSE: Although platinum based chemotherapy is known to improve the survival duration for the patients with non-small cell lung cancer, the role of platinum for elderly patient is not yet clear. We administered gemcitabine and carboplatin combination therapy to elderly patients with NSCLC. The aim of this study was to evaluate the efficacy and toxicities of this regimen for elderly patients. MATERIALS AND METHODS: The eligibility criteria were as follows: pathologically confirmed NSCLC, an age > or = 65 years, advanced disease with stage IIIB or IV and the patients were chemotherapy-naive. The treatment regimen was as follows; gemcitabine 1,000 mg/m2 was administered on days 1 and 8 and carboplatin AUC=5 was administered on day 1. This regimen was repeated every 3 weeks. The efficacy was evaluated in terms of the response rate, the time to progression and the overall survival duration. RESULTS: From Dec 2001 to Feb 2005, a total of 20 pa-tients were entered into this study. The median patient age was 68 years (range: 65~75). 19 patients were evaluable for their treatment response. A partial response was obtained in 8 patients (response rate: 42.1%, 95% CI: 19.4~64.8%). The median time to progression and the survival duration were 136 days and 453 days, respectively. Among a total of 65 cycles of treatment, grade 3 or 4 leukopenia and thrombocytopenia were observed in 7.7% and 13.9% of the cycles, respectively. Grade 3 or 4 vomiting was observed in 7.7% of the cycles. Grade 3 skin rash developed in 1.5% of the cycles. 1 patient died of septic shock after chemotherapy. CONCLUSIONS: Gemcitabine and carboplatin combination chemotherapy was relatively safe and effective for treating elderly patients with NSCLC.

Angiosarcoma is a very rare neoplasm, and even more so in the gastrointestinal tract where its distinction from adenocarcinoma may be extremely difficult. We report a case of multifocal epithelioid angiosarcoma of the stomach in a 65-year-old woman. Histologically, the tumor foci were composed of haphazard, anastomosing channels lined by malignant endothelial cells with epithelioid features. Those neoplastic cells stained positive for CD31, CD34, and factor VIII-related antigen.
