Abstract
Gene amplification represents one of the molecular mechanisms of oncogene overexpression in many types of tumors. Homogeneously staining regions (HSRs) are cytogenetic hallmarks of gene amplification. Rhabdomyosarcoma is the most common malignant soft-tissue tumor in children. RMS-YM is an embryonal rhabdomyosarcoma cell line that possesses 3 HSRs. This cytogenetic finding suggests the presence of gene amplifications associated with tumor development or progression in RMS-YM. Here, using fluorescence in situ hybridization, we detected high amplification of the MDM2 gene in the HSRs of RMS-YM. We also refined the region of the amplicon and identified that the FRS2 gene and others are amplified in RMS-YM. MDM2 and FRS2 play important roles as a regulator of p53 and a mediator of FGF signaling, respectively, and thus are potential molecular targets for therapy in many different tumors. RMS-YM may be useful for studies of the molecular pathways of tumorigenesis and tumor progression in rhabdomyosarcoma and for in vitro evaluation of newly developed therapeutic agents that target MDM2 or FRS2.

Abstract
A 72-year-old woman was referred to our hospital with Stage IV non-small-cell lung cancer (NSCLC). Chest computed tomography revealed a mass in the upper lobe of the right lung, with pleural effusion. Cytologic examination identified adenocarcinoma cells in the right pleural effusion. Furthermore, both a deletion mutation in exon 19 and a threonine-methionine substitution mutation at position 790 in exon 20 (T790M) were detected in the epidermal growth factor receptors (EGFR) in the malignant cells. As systemic chemotherapy consisting of carboplatin and pemetrexed or erlotinib proved ineffective, docetaxel monotherapy was initiated as a third-line treatment. Following salvage chemotherapy, her Eastern Cooperative Oncology Group performance status improved from 3 to 1, with tumor regression over 5 months. To the best of our knowledge, this is the first report of successful docetaxel treatment for a patient with NSCLC harboring the T790M EGFR-activating mutation identified before treatment with EGFR tyrosine kinase inhibitors.

Abstract
Tumors are presumed to contain a small population of cancer stem cells (CSCs) that initiate tumor growth and promote tumor spreading. Multidrug resistance in CSCs is thought to allow the tumor to evade conventional therapy. This study focused on expression of CD133 and CD87 because CD133 is a putative marker of CSCs in some cancers including lung, and CD87 is associated with a stem-cell-like property in small-cell lung cancer (SCLC). Six SCLC cell lines were used. The expression levels of CD133 and CD87 were analyzed by real-time quantitative reverse transcription-polymerase chain reaction and flow cytometry. CD133+/- and CD87+/- cells were isolated by flow cytometry. The drug sensitivities were determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Non-obese diabetic/severe combined immunodeficiency mice were used for the tumor formation assay. SBC-7 cells showed the highest expression levels of both CD133 and CD87 among the cell lines. CD133-/CD87-, CD133+/CD87-, and CD133-/CD87+ cells were isolated from SBC-7 cells; however, CD133+/CD87+ cells could not be obtained. Both CD133+/CD87- and CD133-/CD87+ subpopulations showed a higher resistance to etoposide and paclitaxel and greater re-populating ability than the CD133-/CD87- subpopulation. CD133+/CD87- cells contained more G0 quiescent cells than CD133-/CD87- cells. By contrast, CD133-/CD87- cells showed the highest tumorigenic potential. In conclusion, both CD133 and CD87 proved to be inadequate markers for CSCs; however, they might be beneficial for predicting resistance to chemotherapy.

Abstract
OBJECTIVE We examined the prognosis of patients with leptomeningeal metastasis (LM) from non-small cell lung cancer (NSCLC) and that stratified by epidermal growth factor receptor (EGFR) mutation status in LM patients receiving EGFR-tyrosine kinase inhibitors (TKIs). METHODS We retrospectively analyzed a series of 91 consecutive NSCLC patients with LM between 2001 and 2010. RESULTS Most of the LM patients had adenocarcinoma histology and a poor performance status (PS). The median survival time (MST) for all patients was 3.6 months. Adenocarcinoma and TKI treatment were associated with a better prognosis. Among the patients, 51 received EGFR-TKIs. Of these, the EGFR mutation status was assessed in 30 patients; 7 (23%) showed no mutation (group 1), 10 (33%) had a mutation in exon 21 (group 2), and 13 (43%) had deletions in exon 19 (group 3). Interestingly, PS was significantly improved in groups 2 and 3 but not in group 1. The MST in these subgroups was 1.4, 7.1, and 11.0 months in groups 1, 2, and 3, respectively (p<0.001). The median time to progression or symptom deterioration was 0.9, 2.0, and 7.8 months for groups 1, 2, and 3, respectively (p<0.001). A multivariate analysis showed that EGFR-mutant tumors were associated with a better prognosis in patients receiving EGFR-TKIs. CONCLUSIONS The prognosis for patients with LM from NSCLC was still poor. Survival after the initiation of EGFR-TKI treatment differed according to the type of EGFR mutation, suggesting the potential benefit of TKIs for patients with EGFR mutations, even though they suffered from LM.

Abstract
BACKGROUND/AIM Although small-cell lung cancer (SCLC) is sensitive to anticancer agents, most patients with SCLC experience relapse and die within two years. Here, we examined the relationship between natural killer (NK) cells and adhesion molecules on SCLC cell lines. MATERIALS AND METHODS The expression levels of HLA class I, β2-microglobulin, Fas/Apo-1 receptor (FAS) and adhesion molecules on SCLC cell lines were examined by flow cytometry. The cytotoxicity of activated NK cells from SCLC patients was examined using (51)Cr-release assay. RESULTS HLA class I antigen and β2-microglobulin expression levels in SCLC cell lines were lower than those in healthy volunteers. SCLC cell lines were susceptible to lysis by activated NK cells but this showed no correlation with expression levels of adhesion molecules. CONCLUSION Target cell susceptibility to activated NK cells from five SCLC patients correlated with survival benefit; target cell susceptibility to activated NK cells may be a surrogate marker of outcome for patients with SCLC.

Abstract
A 72-year-old woman was referred to our hospital for palliative care. Fifteen years earlier, she had undergone total hysterectomy and radiotherapy for cervical cancer. One year before her referral, she visited a hospital due to a gait disturbance and was diagnosed with lymphangiosarcoma. The level of coagulation factor VIII plasma activity was >201% (normal range: 62-145%) and the immunohistochemical results were positive for factor VIII-related antigen in a tumor specimen. To the best of our knowledge, this is the first report of high coagulation factor VIII plasma activity in a patient with lymphangiosarcoma.

Abstract
The patient was a 71-year-old man who underwent a right hemicolectomy for ascending colon cancer (pT3, pN1, pM0) and who opted not to receive adjuvant chemotherapy. Eight months later, multiple liver metastases occurred. He therefore received FOLFOX4 (5-fluorouracil/leucovorin and 85 mg/m2 oxaliplatin) therapy, up to a total of 5 courses, and showed a partial response. While receiving the sixth course of FOLFOX4, he complained of chest pain and systemic itching approximately 15 min after the start of chemotherapy. An electrocardiogram revealed typical signs of ischemia. Coronary arteriography showed that the coronary arteries were intact. Believing the chest pain to be merely coincidental, we continued with the same therapy. However, he again developed the same chest pain during the seventh cycle of FOLFOX4 and treatment was stopped. We concluded that the patient’s symptoms were due to acute coronary syndrome (ACS) associated with the FOLFOX4 regimen. Variant angina as a type of ACS is a rare adverse effect of FOLFOX4. Clinicians should be aware of this potential adverse effect when monitoring patients receiving FOLFOX4.

Abstract
We describe a case of pulmonary diffuse large B-cell lymphoma (DLBCL), which was thought to arise from extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). A 68-year-old woman presented with a 2-month history of cough and bloody sputum. The chest X-ray and computed tomography revealed a mass with cavitation in the right lower lobe. Transbronchial biopsy specimens revealed a granulomatous infiltration without malignant cells. However, diagnosis of MALT lymphoma was established from gastric biopsy specimen. Subsequently, a right lower lobectomy was performed because of hemoptysis. Examination of the resected specimen revealed a diffuse large B-cell lymphoma, which was considered to have transformed from MALT lymphoma, because both lung and stomach lesions had the chromosomal translocation t(11;18)(q21;q21) in common. In addition, there were no nodules, masses, alveolar or interstitial infiltrates in the lung fields, which are usually observed in the case of marginal zone B-cell lymphoma of bronchial mucosa-associated lymphoid tissue. These findings indicate that involvement of DLBCL have to be considered in patients with MALT lymphoma and cavitary lesion of the lung.

Abstract
A 66-year-old Japanese man with pancreatic cancer received eleven courses of gemcitabine monotherapy. The tumor responded to gemcitabine until metastatic liver tumors progressed. Subsequently, he was treated with S-1, an oral fluoropyrimidine anticancer agent, as salvage chemotherapy. Forty-two days after initiating S-1, he presented with dyspnea and fever. Chest computed tomography showed diffuse interstitial lesions with thickening of the alveolar septa and ground glass opacity. Serum KL-6 level was elevated to 1,230 U/mL and he did not use any other drugs except insulin. Thus, the development of interstitial lung disease (ILD) was considered to be due to S-1. Arterial blood oxygen pressure was 49.6 Torr in spite of oxygen administration (5 L/min). Steroid therapy improved his symptoms and the interstitial shadows on chest radiograph. Although S-1-induced ILD has mostly been reported to be mild, clinicians should be aware that S-1 has the potential to cause fatal ILD.

Abstract
BACKGROUND CD5-positive (CD5+) diffuse large B-cell lymphoma (DLBCL) shows poor prognosis and frequent central nervous system (CNS) relapses under anthracycline-containing chemotherapy. The aim of this study was to determine the prognosis and CNS relapse incidence of CD5+ DLBCL in the rituximab era. PATIENTS AND METHODS We analyzed 337 patients with CD5+ DLBCL who received chemotherapy with (R-chemotherapy group; n = 184) or without (chemotherapy group; n = 153) rituximab. RESULTS No significant difference was found in clinical background comparisons between the two groups. In the R-chemotherapy group, 60% of the patients were older than 65 years at diagnosis. Both the complete response rate and overall survival (OS) were significantly better in the R-chemotherapy group (P = 0.0003 and P = 0.002, respectively). Multivariate analysis confirmed that chemotherapy without rituximab was associated with unfavorable OS. However, the probability of CNS relapse did not differ between the two groups (P = 0.89). The CNS relapse was strongly associated with short OS (P < 0.0001). In the R-chemotherapy group, 83% of patients who experienced CNS relapse had parenchymal disease. CONCLUSIONS Our results indicate that rituximab improves the OS of patients with CD5+ DLBCL but does not decrease the CNS relapse rate. More effective treatments with CNS prophylaxis are needed for CD5+ DLBCL patients.

Abstract
The correlation between the geometric and electronic structures of Zn-phthalocyanine (ZnPc) and F16ZnPc on Cu(111) were studied by x-ray standing wave and angle-resolved photoemission spectroscopy. We found evidence for a distortion of the planar molecules upon adsorption, with the central Zn atom in the molecule protruding towards the substrate. This modifies the energy levels of both the molecule and the substrate, which appear as interface states. The site-specific geometric and electronic relaxations are an important effect for organic-metal interface energetics.

Abstract
The endogenous gibberellins (GAs) were examined from young vegetative shoots of the dominant mutant, Dwarf-8, a GA-nonresponder, and normal maize; GA(44), GA(17), GA(19), GA(20), GA(29), GA(1), and GA(8), members of the early-13-hydroxylation pathway, were identified from both kinds of shoots by full-scan mass spectra and Kovats retention indices. In addition, we report the identification of 3-epi-GA(1), GA(3), GA(4), GA(5), GA(7), GA(9), GA(12), GA(15), GA(24), GA(34), and GA(53) by using the same criteria. [1,7,12,18-(14)C(4)]GA(53) and -GA(44), [17-(2)H(2)]GA(19), and [17-(13)C,(3)H(2)]GA(20), -GA(29), -GA(1), -GA(8), and -GA(5) were used as internal standards to determine the endogenous levels of these GAs by measurement of isotope dilution, using capillary gas chromatography and selected ion monitoring. Shoots of Dwarf-8 accumulate relatively high levels of GA(20), GA(1), and GA(8). The accumulation of GA(1) appears to be related to gene dosage. Since Dwarf-8 contains the same pattern of GAs as normals (including GA(1) and GA(3)), the genetic control point probably lies after GA(1) (and GA(3)). Thus Dwarf-8 may be a GA receptor mutant or a mutant that controls a product downstream from the binding of the bioactive GA to a receptor.

Abstract
The central effects of L-proline, D-proline and trans-4-hydroxy-L-proline were investigated by using the acute stressful model with neonatal chicks in Experiment 1. Sedative and hypnotic effects were induced by all compounds, while plasma corticosterone release under isolation stress was only attenuated by L-proline. To clarify the mechanism by which L-proline and D-proline induce sedative and hypnotic effects, the contribution of the strychnine-sensitive glycine receptor (glycine receptor) and N-methyl-D-aspartate glutamate receptor (NMDA receptor) were further investigated. In Experiments 2-3, the glycine receptor antagonist strychnine was co-injected intracerebroventricular (i.c.v.) with L-proline or D-proline. The suppression of isolation-induced stress behavior by D-proline was attenuated by strychnine. However, the suppression of stress behavior by L-proline was not attenuated. In Experiment 4, the NMDA receptor antagonist (+)-MK-801 was co-injected i.c.v. with L-proline. The suppression of stress behavior by L-proline was attenuated by (+)-MK-801. These results indicate that L-proline and D-proline differentially induce sedative and hypnotic effects through NMDA and glycine receptors, respectively.

Abstract
We encountered a rare case of liposarcoma of the ascending colon mesenterium. A 53-year-old man visited our hospital because of a mass, 12x8cm in diameter, in the right upper abdomen. On computed tomography (CT), the tumor showed irregular density with a smooth surface and was enhanced irregularly. A part of the tumor protruded into the colon in the upper portion of the ascending colon. The tumor was surgically resected by right hemicolectomy. Histological diagnosis of the tumor was well-differentiated liposarcoma, sclerosing variant. Radiological findings seemed to reflect the pathological findings well.

Abstract
Although previous studies have claimed that Pungtungia herzi (Cyprinidae) is an obligate brood parasite, in this study a significant proportion of P. herzi egg masses was found in crevices formed by stones and rocks, which was not guarded by hosts. Egg masses were also found in almost all nests of a goby Odontobutis obscura, suggesting that P. herzi has two alternative reproductive tactics: brood parasitic spawning and non-parasitic crevice spawning, the latter of which may occur when a shortage of reproductive resources (i.e. host nests) exists. The hatching rates of parasitic egg masses were significantly higher than those of non-parasitic egg masses, and the hatching rate of P. herzi eggs exhibited a strong positive correlation with continuous egg guarding by a reproductive O. obscura male. These results indicate that brood parasitism effectively improves reproductive success in P. herzi. The alternative reproductive tactic of this species suggests that brood parasitism has evolved directly from crevice spawning via the sharing of spawning habitat with host species.

Abstract
After 1990's, the development of new generation anti-cancer agents produced encouraging improvement of prognosis in inoperable or relapsed stomach cancer and colorectal cancer. However, non-hematological toxicity, such as peripheral neuropathies, become a new dose-limiting toxicity. In several new generation drugs, measures for controlling peripheral neuropathy had not been established besides dose modification or schedule modification. We tried to control the peripheral neuropathy induced by anti-cancer agents with the assistance of an adjuvant analgesics ladder. A total of 18 digestive cancer patients who presented with peripheral neuropathy of grade 1 or more(NCI-CTCAE ver 3.0), in the chemotherapy including Taxol or Oxaliplatin, were enrolled. The first stage of the adjuvant analgesics ladder was set as the antidepressant(amoxapin), the second stage was anticonvulsive drugs(valproic acid or clonazepam) and the third stage was antiarrhythmic drug(mexiletine). In each stage, if the drug turned out to be ineffective after two / weeks follow-up, it shifted to the next stage. The response rate of each step was 61.1%(11/18)of the first stage, 50.0%(5/10)of the 2nd stage, 50.0%(2/4)of the 3rd stage, and the overall response rate was 77.8%. The discontinuance of cancer treatment by peripheral neuropathy was observed only in 1 patient 5.5%(1/18)in the Taxol administered group. The toxicity profile was skin eruption and drowsiness, but the skin eruption was observed only in 1 patient at the 3rd stage and the drowsiness in 2 patients at the 2nd stage. It appears that the method to control the peripheral neuropathy induced by anti-cancer agents with the assistance of adjuvant analgesics ladder was effective and safe, but a large-scale clinical trial was warranted.

Abstract
We describe an 87-year-old woman with a large ileal gastrointestinal stromal tumor (GIST) causing hemoperitoneum. A CT scan demonstrated a large heterogeneous mass measuring about 13 cm × 11 cm in the pelvis and hemoperitoneum, with a non-uniform enhancement pattern. The mass was diagnosed as a GIST originating from the gastrointestinal tract. She underwent an urgent laparotomy and an ileal GIST with a rupture was found 130 cm from the anal to the Treitz’s ligament. Hemoperitoneum caused by ileal GIST rupture is a rare condition. Bleeding in the large tumor leading to rupture of the capsule might cause hemoperitoneum in the present case.

Abstract
A solitary Peutz-Jeghers-type hamartomatous polyp in the duodenum is rare, and few reports have described its characteristic endoscopic features. We describe three cases of solitary Peutz-Jeghers-type hamartomatous polyp and their endoscopic findings in detail. The polyp in all of our three cases showed an irregularly lobular or nodular surface, whereas adenomas often show a regularly nodular or granular surface. The color of the polyp was whitish in all of our cases. In the present cases, close observation by endoscopy revealed that the solitary Peutz-Jeghers-type hamartomatous polyps looked whitish because of the presence of diffusely scattered white spots on the surface of the polyps. Duodenal polyps that exhibit the aforementioned endoscopic characteristics may be diagnosed as Peutz-Jeghers-type hamartomatous polyps and treated by polypectomy because of the malignant potential.

Abstract
An organized hematoma is a chronic state of fibrotic tissue surrounding a hemorrhage. A mass lesion resulting from hematoma in the maxillary sinus was first reported in 1917, and the term, "blood boil," was clinically coined from such features as encapsulated blood and locally aggressive behavior. Subsequently, others have reported lesions with a similar appearance and clinical course, and now, in Japan, blood boil is used as a clinical term for such lesions. Factors that may predispose a patient to hematoma formation vary, and the pathogenesis of the mass is still uncertain. The lesions are mainly composed of an organized hematoma, regardless of their origin. We present 2 cases of organized maxillary sinus hematomas that have unusual radiologic findings and correlate these findings with the histopathologic findings.

Abstract
Intracerebroventricular (i.c.v.) injection of L-serine was shown to have sedative and hypnotic effects on neonatal chicks under acute stressful conditions. To clarify the central mechanism of these effects of L-serine, two experiments were done. First, we focused on the glycogenic pathway in which L-serine is converted into pyruvate and finally glucose. I.c.v. administration of pyruvate (0.84 micromol) did not induce any behavioral and endocrinological changes, while L-serine and glucose triggered sedative and hypnotic effects. Secondly, the relationship between the sedation by L-serine and the metabolism into other amino acids which have sedative effects was investigated in the telencephalon and diencephalon. In both brain areas, a dose-dependent increase was seen in L-serine, although other amino acids were not changed. In the present study, it was concluded that the sedative action of L-serine was not due to the action of its metabolite pyruvate, or to the action of other amino acids.

Abstract
A 74-year-old woman visited our hospital for a health checkup, and liver dysfunction and cholangiectasis were detected. Further examinations revealed a protruding lesion spreading diffusely from the upper to the lower extra-hepatic bile duct. On a diagnosis of extra-hepatic bile duct cancer, the patient underwent pancreato-duodenectomy with preservation of the pyloric ring. Small papillary denticulate lesions, forming papillary adenocarcinoma, was scattered over a flat granular lesion of atypical hyperplasia. This morphological pattern is rare, and suggests that the cancer cells may have derived from atypical hyperplastic epithelium.

Abstract
Loss or down-regulation of HLA expression has been demonstrated in various types of solid tumors and is considered to be one of the mechanisms of tumor immunoescape. The effectiveness of immunotherapy using tumor-specific antigens (TSA) largely depends on the expression of the appropriate HLA class I alleles on the tumor cells. We analyzed the allele-specific HLA class I surface expression of six lung cancer cell lines using a broad panel of allele-specific monoclonal antibodies, as well as the effect of IFN-gamma on HLA expression. Flow cytometric analysis displayed a wide range, from minimal to a high degree of expression of monomorphic HLA class I among the studied cell lines. Allele-specific loss or down-regulation of HLA also was observed in 5 out of 6 cell lines. Our results suggest that lung cancer patients considered for specific immunotherapy should be examined with respect to the expression of specific HLA class I allele binding the TSA.

Abstract
Primary effusion lymphoma (PEL) is a newly described high-grade B cell lymphoma developing in association with human herpes virus type 8 (HHV-8) in human immunodeficiency virus (HIV)-infecting individuals. Common variable immunodeficiency (CVID) is a primary immunodeficiency disease characterized by reduced serum immunoglobulin and heterogeneous clinical features. The risk of cancer in CVID patients is increased. Here, we describe a PEL that developed in the pleural and pericardial cavities of an HIV-negative and HHV-8-negative patient with CVID.

Abstract
This study identifies and characterizes a basic non-S RNase in the styles with stigmas of sweet cherry (Prunus avium L.), a member of the Rosaceae subfamily Amygdaloideae, which has an RNase-based gametophytic self-incompatibility system. Internal sequences of putative non-S RNases (RNase PA1 and PA2) were determined, and a cDNA for PA1 was obtained. The deduced amino acid sequence of PA1 contained two conserved sequence motifs essential for T2/ S-type RNase activity. PA1 shows 20-30% sequence identity to S-RNases of Rosaceae, Solanaceae and Scrophulariaceae, and non-S RNases of higher plants. Transcription of the PA1 gene was specific to the styles with stigmas, and the gene was not expressed in other tissues. Although PA1 resembles RNase X2, a non-S RNase from Petunia inflata, the placement of PA1 and RNase X2 in the phylogenetic tree was quite different. Placement of PA1 was also distinct from that of rosaceous S-RNases, while RNase X2 was incorporated in the clade of S-RNases from the Solanaceae. The sole intron in the PA1 gene is located at a position equivalent to that of the second intron of amygdaloid S-RNase genes, and that of the only intron in most other S-RNase genes. Genomic Southern analysis revealed the presence of sequences homologous to PA1 in all of the other four Prunus species tested, suggesting that PA1 has an important physiological function. The significance of the discovery of PA1 is discussed in terms of the origin and evolution of S-RNases and self-incompatibility in Rosaceae.

Abstract
Self-compatible cultivars of Japanese apricot ( Prunus mume Shieb. et Zucc.), a tree species that normally shows S-RNase-based self-incompatiblity, have a horticultural advantage over self-incompatible cultivars. Inheritance of self-compatibility and a common S(f)-RNase allele that is observed in self-compatible cultivars was investigated using progenies from controlled crosses. Total DNAs were isolated from the parents and progenies of seven crosses that included at least one self-compatible cultivar as a parent. These DNAs were PCR-amplified with the Pru-C2 and PCE-R primer pair to determine S-haplotypes of the parents and progenies. A novel S-haplotype, S(8), was found. In all crosses examined, the S(f)-RNase gene was inherited from either the seed or pollen parent as a pistil S-allele in a non-functional S-haplotype. Self-compatibility of about 20 trees each from reciprocal crosses of 'Benisashi ( S(7) S(f))' and 'Shinpeidayu ( S(3) S(f))', and 26 selections from 16 different crosses was tested by pollination and pollen-tube growth studies. Cosegregation of the S(f)-RNase allele and self-compatibility was confirmed with all but selection 1K0-26 ( S(3) S(7)). Selection 1K0-26 ( S(3) S(7)) that originated from 'Benisashi ( S(7) S(f))' x 'Koshinoume ( S(3) S(f))' appeared to be self-compatible even without the S(f)-RNase allele. The possible role of pollen- S, a presumably existing pollen component of gametophytic self-incompatibility, is discussed.

Abstract
Eighteen elderly patients aged 76 years or older with small cell lung cancer were treated with carboplatin (AUC = 4 mg/ml.min, i.v. day 1) and etoposide (70 mg/m2 i.v. day 1-3) and 17 patients were evaluable. The median age of the study population was 77 years (range: 76-81). Eight patients had limited disease (LD) and nine did extensive disease (ED). The overall response rate was 88% for LD patients and 67% for ED patients. Median survival time was 219 days for LD patients and 158 days for ED patients. Grade 3 and 4 leukopenia, neutropenia, thrombocytopenia and anemia occurred in 41%, 76%, 24% and 6% of patients, respectively. There was one treatment-related death due to pneumonitis.
