RESUMEN

BACKGROUND: In this randomized phase II study, we evaluated the efficacy and safety of sorafenib in combination with capecitabine and cisplatin (XP) as first-line chemotherapy in advanced gastric cancer. PATIENTS AND METHODS: Patients with metastatic gastric or gastroesophageal junction adenocarcinoma were randomized (1:1) to receive either sorafenib plus XP (S + XP) or XP alone. In cases of disease progression in the XP arm, crossover to sorafenib alone was allowed. The primary endpoint was progression-free survival (PFS). The secondary endpoints included overall survival (OS), response rates, safety profiles, and biomarkers, and the response rates and PFS with secondline sorafenib alone after progression in the XP arm. RESULTS: Between Jan 2011 and Feb 2013, a total of 195 patients were accrued (97 in the S + XP arm and 98 in the XP alone arm). The overall response rate was 54% with S + XP, and 52% with XP alone (p = 0.83). With a median follow-up of 12.6 months (range, 0.1-29.2), the median PFS assessed by independent review was 5.6 months in the S + XP arm and 5.3 months in the XP arm (hazard ratio [HR] 0.92, 95% confidence interval [CI] 0.67-1.27, p = 0.61). Overall survival was not different between the two arms (median 11.7 vs. 10.8 months; HR 0.93, 95% CI 0.65-1.31, p = 0.66). Frequencies of grade 3/4 toxicities were similar between the S + XP and XP alone arms, except for neutropenia (21% vs. 37%), anorexia (0% vs. 5%), and hand-foot skin reaction (7% vs. 1%). Among 51 patients who crossed over to sorafenib alone after disease progression in the XP arm, there was no objective response and their median PFS was 1.3 months (95% CI, 1.2-1.7). CONCLUSION: The addition of sorafenib to XP chemotherapy was safe but not more effective than XP alone for first-line treatment of metastatic gastric cancer.

RESUMEN

OBJECTIVES: Treatment with trastuzumab and chemotherapy significantly improves the outcome in patients with human epidermal growth factor receptor 2 (HER2)-positive advanced gastric cancer (AGC). CT-P6 (trastuzumab-pkrb; Herzuma) is a trastuzumab biosimilar approved for the treatment of HER2-positive gastric cancer. In this study, we aimed to compare the efficacy and safety of CT-P6 and reference trastuzumab as first-line treatment for HER2-positive AGC. MATERIALS AND METHODS: The medical records of 102 patients with HER2-positive AGC treated with first-line trastuzumab-based chemotherapy were retrospectively reviewed. These patients were treated with either reference trastuzumab (n=72) or a biosimilar (n=30). Treatment outcomes, such as objective response rate, progression-free survival (PFS), and overall survival (OS), were compared between the reference and biosimilar groups. RESULTS: The objective response rate of both groups (52.8% and 56.8% in the reference and biosimilar groups, respectively) were comparable (P=0.72). No statistically significant difference was observed with the reference versus biosimilar trastuzumab for PFS (median PFS, 6.9 vs. 5.4 mo; P=0.98) or OS (median OS, 12.3 mo vs. not reached; P=0.42). Safety profiles were similar between the 2 groups. CONCLUSIONS: Biosimilar trastuzumab showed equivalent outcome to reference trastuzumab, with similar adverse events. Biosimilar trastuzumab can suitably and safely replace trastuzumab as a reference for the treatment of HER2-positive AGC.

RESUMEN

OBJECTIVES: Trastuzumab is used as an agent against human epidermal growth factor receptor 2 (HER2)-positive advanced gastric cancer (AGC). The aim of this study was to determine how HER2 gene amplification and neutrophil-to-lymphocyte ratio (NLR) could predict long-term survival in AGC patients that underwent trastuzumab-based chemotherapy. METHODS: We retrospectively reviewed medical records of 112 patients between 28 and 91 years old (median of 66 y) with AGC treated with first-line trastuzumab-based chemotherapy. The level of HER2 gene amplification was determined by the HER2/centromere enumerator probe 17 (CEP17) ratio and HER2 gene copy number (GCN). NLR was calculated as the neutrophil count divided by the lymphocyte counts. RESULTS: Median HER2/CEP17 ratio, HER2 GCN, and NLR values were 2.85, 7.1, and 2.81, respectively. Objective response rate in both high HER2/CEP17 ratio (59.4% vs. 28.1%, P=0.012) and HER2 GCN groups (62.1% vs. 33.3%, P=0.032) was higher than that of each group. High NLR correlated with significantly worse median overall survival (OS) (median OS, 8.2 vs. 18.9 mo, P=0.002) and progression free survival (PFS) (median PFS: 5.1 vs. 8.0 mo, P=0.005). However, median OS and PFS were not significantly different according to HER2/CEP17 ratio or HER2 GCN. In the multivariate analysis, high NLR, Eastern Cooperative Group performance status, and poorly differentiated/signet ring cell type were independent factors for OS. CONCLUSIONS: NLR was a significant predictor of long-term survival in AGC patients treated with first-line trastuzumab-based chemotherapy. Future validation of prospective trials with larger patient populations will be needed.

RESUMEN

Backgrounds/Aims: Watson for Oncology (WFO) is a cognitive technology that processes medical information by analyzing the latest evidence and guidelines. However, studies of the concordance rate between WFO and clinicians for advanced gastric cancer (AGC) are lacking. Methods: We retrospectively reviewed 65 patients with AGC who consulted WFO and the Gachon Gil Medical Center multidisciplinary team (GMDT) in 2016 and 2017. The recommendations of WFO were compared with the opinions of the GMDT. WFO provided three treatment options: recommended (first treatment option), for consideration (second treatment option), and not recommended. Results: In total, 65 patients (mean age 61.0 years; 44 males and 21 females) were included in the study. The concordance rate between WFO and the GMDT was 41.5% (27/65) at the recommended level and 87.7% (57/65) at the for consideration level. The main causes of discordance between WFO and the GMDT were as follows. First, WFO did not consider the medical history. Second, WFO recommended the use of agents that are considered outdated in Korea. Third, some patients wanted to be involved in a clinical trial. Fourth, some patients refused to use the biologic agents recommended by WFO for financial reasons as they were not covered by medical insurance. Conclusions: The concordance rate at the recommended level was relatively low but was higher at the for consideration level. Discordances arose mainly from the different medical circumstances at the Gachon Gil Medical Center (GMC) and the Memorial Sloan Kettering Cancer Center (MSKCC), the main WFO consulting center. The utility of WFO as a tool for supporting clinical decision making could be further improved by incorporating regional guidelines.

RESUMEN

BACKGROUND: Patients with advanced hepatocellular carcinoma and increased α-fetoprotein concentrations have poor prognosis. We aimed to establish the efficacy of ramucirumab in patients with advanced hepatocellular carcinoma and α-fetoprotein concentrations of 400 ng/mL or higher. METHODS: REACH-2 was a randomised, double-blind, placebo-controlled, phase 3 trial done at 92 hospitals, clinics, and medical centres in 20 countries. Eligible patients were aged 18 years or older and had histologically or cytologically confirmed hepatocellular carcinoma, or diagnosed cirrhosis and hepatocellular carcinoma, Barcelona Clinic Liver Cancer stage B or C disease, Child-Pugh class A liver disease, Eastern Cooperative Oncology Group (ECOG) performance statuses of 0 or 1, α-fetoprotein concentrations of 400 ng/mL or greater, and had previously received first-line sorafenib. Participants were randomly assigned (2:1) via an interactive web response system with a computer-generated random sequence to 8 mg/kg intravenous ramucirumab every 2 weeks or placebo. All patients received best supportive care. The primary endpoint was overall survival. Secondary endpoints were progression-free survival, proportion of patients achieving an objective response, time to radiographic progression, safety, time to deterioration in scores on the Functional Assessment of Cancer Therapy Hepatobiliary Symptom Index 8 (FHSI-8), and time to deterioration in ECOG performance status. We also pooled individual patient data from REACH-2 with data from REACH (NCT01140347) for patients with α-fetoprotein concentrations of 400 ng/mL or greater. Efficacy analyses were by intention to treat, whereas safety analyses were done in all patients who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, number NCT02435433. FINDINGS: Between July 26, 2015, and Aug 30, 2017, 292 patients were randomly assigned, 197 to the ramucirumab group and 95 to the placebo group. At a median follow-up of 7·6 months (IQR 4·0-12·5), median overall survival (8·5 months [95% CI 7·0-10·6] vs 7·3 months [5·4-9·1]; hazard ratio [HR] 0·710 [95% CI 0·531-0·949]; p=0·0199) and progression-free survival (2·8 months [2·8-4·1] vs 1·6 months [1·5-2·7]; 0·452 [0·339-0·603]; p<0·0001) were significantly improved in the ramucirumab group compared with the placebo group. The proportion of patients with an objective response did not differ significantly between groups (nine [5%] of 197 vs one [1%] of 95; p=0·1697). Median time to deterioration in FHSI-8 total scores (3·7 months [95% CI 2·8-4·4] vs 2·8 months [1·6-2·9]; HR 0·799 [95% CI 0·545-1·171]; p=0·238) and ECOG performance statuses (HR 1·082 [95% CI 0·639-1·832]; p=0·77) did not differ between groups. Grade 3 or worse treatment-emergent adverse events that occurred in at least 5% of patients in either group were hypertension (25 [13%] in the ramucirumab group vs five [5%] in the placebo group), hyponatraemia (11 [6%] vs 0) and increased aspartate aminotransferase (six [3%] vs five [5%]). Serious adverse events of any grade and cause occurred in 68 (35%) patients in the ramucirumab group and 28 (29%) patients in the placebo group. Three patients in the ramucirumab group died from treatment-emergent adverse events that were judged to be related to study treatment (one had acute kidney injury, one had hepatorenal syndrome, and one had renal failure). INTERPRETATION: REACH-2 met its primary endpoint, showing improved overall survival for ramucirumab compared with placebo in patients with hepatocellular carcinoma and α-fetoprotein concentrations of at least 400 ng/mL who had previously received sorafenib. Ramucirumab was well tolerated, with a manageable safety profile. To our knowledge, REACH-2 is the first positive phase 3 trial done in a biomarker-selected patient population with hepatocellular carcinoma. FUNDING: Eli Lilly.

RESUMEN

BACKGROUND: Pathologic diagnosis of central nervous system (CNS) neoplasms is made by comparing light microscopic, immunohistochemical, and molecular cytogenetic findings with clinicoradiologic observations. Intraoperative frozen cytology smears can improve the diagnostic accuracy for CNS neoplasms. Here, we evaluate the diagnostic value of cytology in frozen diagnoses of CNS neoplasms. METHODS: Cases were selected from patients undergoing both frozen cytology and frozen sections. Diagnostic accuracy was evaluated. RESULTS: Four hundred and fifty-four cases were included in this retrospective single-center review study covering a span of 10 years. Five discrepant cases (1.1%) were found after excluding 53 deferred cases (31 cases of tentative diagnosis, 22 cases of inadequate frozen sampling). A total of 346 cases of complete concordance and 50 cases of partial concordance were classified as not discordant cases in the present study. Diagnostic accuracy of intraoperative frozen diagnosis was 87.2%, and the accuracy was 98.8% after excluding deferred cases. Discrepancies between frozen and permanent diagnoses (n = 5, 1.1%) were found in cases of nonrepresentative sampling (n = 2) and misinterpretation (n = 3). High concordance was observed more frequently in meningeal tumors (97/98, 99%), metastatic brain tumors (51/52, 98.1%), pituitary adenomas (86/89, 96.6%), schwannomas (45/47, 95.8%), high-grade astrocytic tumors (47/58, 81%), low grade astrocytic tumors (10/13, 76.9%), non-neoplastic lesions (23/36, 63.9%), in decreasing frequency. CONCLUSIONS: Using intraoperative cytology and frozen sections of CNS tumors is a highly accurate diagnostic ancillary method, providing subtyping of CNS neoplasms, especially in frequently encountered entities.

RESUMEN

PURPOSE: We conducted a randomized, multicenter, phase III trial to compare S-1 plus docetaxel (DS) with S-1 plus cisplatin (SP) as adjuvant chemotherapy for stage III gastric cancer patients. MATERIALS AND METHODS: Stage III gastric cancer patients who had received curative gastrectomy with D2 lymphadenectomy were randomized into equal groups to receive adjuvant chemotherapy of eight cycles of DS (S-1 70 mg/m2 /day on days 1-14 plus docetaxel 35 mg/m2 on days 1 and 8) every 3 weeks or SP (S-1 70 mg/m2 /day on days 1-14 plus cisplatin 60 mg/m2 on day 1) every 3 weeks. The primary endpoint was 3-year disease-free survival (DFS) rate. RESULTS: Between November 2010 and July 2013, 153 patients (75 patients to DS and 78 patients to SP) were enrolled from 8 institutions in Korea. After the capecitabine plus oxaliplatin was approved based on the CLASSIC study, itwas decided to close the study early. With a median follow-up duration of 56.9 months, the 3-year DFS rate between two groups was not significantly different (49.14% in DS group vs. 52.5% in SP group). The most common grade 3-4 adverse event was neutropenia (42.7% in DS and 38.5% in SP, p=0.351). SP group had more grade 3-4 anemia (1.3% vs. 11.5%, p=0.037), whereas grade 3-4 hand-foot syndrome (4.1% vs. 0%, p=0.025) and mucositis (10.7% vs. 2.6%, p=0.001) were more common in DS group. Fifty-one patients (68%) in DS group and 52 (66.7%) in SP group finished planned treatment. CONCLUSION: Our findings suggest that SP or DS is an effective and tolerable option for patients with curatively resected stage III gastric cancer.

RESUMEN

BACKGROUND/AIMS: We investigated the time taken for patients with metastatic non-small cell lung cancer (NSCLC) to develop brain metastases (BM), as well as their subsequent overall median survival following diagnosis, considering the epidermal growth factor receptor (EGFR) mutational status. METHODS: We retrospectively investigated the medical records of 259 patients diagnosed with advanced NSCLC from January 2010 to August 2013, who were tested for EGFR mutations. The time from the diagnosis of advanced NSCLC to the development of BM and the overall median survival after BM development (BM-OS) were evaluated and compared by EGFR mutational status. RESULTS: Sixty-seven patients (25.9%) developed BM. Synchronous BM occurred more often in patients with EGFR mutation type (MT) (n = 20, 27.4%) compared with EGFR wild type (WT) (n = 27, 14.5%, p < 0.009). The median BM-OS was significantly longer in patients with EGFR MT than in those with EGFR WT (25.7 months vs. 3.8 months, p < 0.001), and a similar trend was noticed for patients with synchronous BM (25.7 months for EGFR MT vs. 6.8 months for EGFR WT, p < 0.001). However, in patients with metachronous BM development, the difference in BM-OS between patients with EGFR MT (14.6 months) and EGFR WT (2.5 months) did not reach statistical significance (p = 0.230). CONCLUSIONS: Synchronous BM was more common in NSCLC patients with EGFR MT than in those with EGFR WT. However, EGFR mutations were associated with significantly longer median BM-OS, especially when the brain was the first metastatic site.

RESUMEN

BACKGROUND: Irinotecan-based chemotherapy is a standard backbone of therapy in patients with metastatic colorectal cancer (CRC) or gastric cancer (GC). However, there is still a paucity of information concerning the efficacy and safety of irinotecan-based regimens in elderly patients. PATIENTS AND METHODS: Using the patient cohort (n = 1,545) from the UGT1A1 genotype study, we compared the efficacy and safety between elderly and nonelderly patients with metastatic CRC (n = 934) or GC (n = 611) who received first- or second-line FOLFIRI (irinotecan, leucovorin, and 5-fluorouracil) chemotherapy. RESULTS: Despite lower relative dose intensity in elderly patients, progression-free survival and overall survival were similar between elderly (age ≥70 years) and nonelderly (<70 years) patients in the CRC cohort (hazard ratio [HR], 1.117; 95% confidence interval [CI], 0.927-1.345; p = .244, and HR, 0.989; 95% CI, 0.774-1.264; p = .931, respectively) and the GC cohort (HR, 1.093; 95% CI, 0.854-1.400; p = .479, and HR, 1.188; 95% CI, 0.891-1.585; p = .241, respectively). In both cohorts, febrile neutropenia (22.1% vs. 14.6% in CRC cohort and 35.2% vs. 22.5% in GC cohort) and asthenia (grade 3: 8.4% vs. 1.7% in CRC cohort and 5.5% vs. 2.9% in GC cohort) were more frequent in elderly patients. In the CRC cohort, mucositis and anorexia were more frequent in elderly patients. In the GC cohort, nausea and vomiting were less frequent in elderly patients. CONCLUSION: The efficacy of the FOLFIRI regimen was similar between elderly and nonelderly patients in both the CRC and the GC cohorts. However, special attention should be paid to elderly patients because of increased risk for febrile neutropenia and asthenia. The Oncologist 2017;22:293-303 IMPLICATIONS FOR PRACTICE: The efficacy of FOLFIRI (irinotecan, leucovorin, and 5-fluorouracil) chemotherapy in elderly patients with metastatic colorectal cancer or gastric cancer was similar to that in nonelderly patients. However, special attention should be paid to elderly patients because of the increased risk for febrile neutropenia and asthenia. These data suggest that the FOLFIRI regimen could be considered as a standard backbone of therapy in elderly patients with metastatic colorectal cancer or gastric cancer and that the clinical decision between doublet and singlet chemotherapy may not be based solely on age. However, the data require further assessment of frailty and performance status.

RESUMEN

Gastrointestinal stromal tumors (GISTs) are rare, but are the most common mesenchymal neoplasm of the gastrointestinal tract. The most common sites of metastasis are liver and peritoneum, while bone metastasis is rare. We report on a patient with skull metastasis after seven years of treatment with imatinib for metastatic GIST. She underwent metastasectomy consisting of craniectomy with excision of the mass, and cranioplasty and continued treatment with imatinib and sunitinib, without evidence of cranial recurrence. She died of pneumonia sepsis one year after metastasectomy. Skull metastasis of GIST is a very rare presentation, and an aggressive multidisciplinary approach should be considered whenever possible.

RESUMEN

OBJECTIVE: Phase I oncology trials have raised concerns that patients' 'unrealistic' optimism could compromise the validity of informed consent, and that patients often participate in trials to conform to physicians' or family members' recommendations. We aimed to determine whether patients or families-given the same information of risk-benefit profile-are more likely to participate in Phase I trials than their physicians and whether people in family or physician situations are more likely to recommend trial participation to patients than they would want for themselves as patients. METHODS: We conducted a hypothetical vignette study with a patient-caregiver-oncologist. Three groups-725 patient-caregiver pairs recruited by 134 oncologists-were asked to assume three different roles as patients, caregivers and physicians and provided a scenario of a hypothetical patient with treatment-resistant cancer. They were asked questions regarding their intention to participate in or to recommend a Phase I clinical trial. RESULTS: Acceptance rates of the trial were as follows: (a) in the patients' role: patients (54.1), caregivers (62.3) and physicians (63.4%); (b) in the caregivers' role: 55.6, 64.7 and 70.9%; (c) in the physicians' role: 66.1, 70.8 and 76.1%. Patients or caregivers were not more positive to the trial than physicians. All three groups showed more positive attitudes toward the clinical trial when they assumed the role of caregiver or physician than that of patient. CONCLUSIONS: Patients and caregivers seem to make as reasonable decisions as physicians; patients seem to take family members' or physicians' recommendation as their legitimate roles rather than as undue pressure.

RESUMEN

BACKGROUND: The association between baseline renal impairment (RI) and the prognosis of diffuse large B-cell lymphoma (DLBCL) was previously not defined. The aim of this study was to evaluate the prognostic value of RI in patients with DLBCL treated with three-weekly rituximab plus cyclophosphamide, Adriamycin, vincristine, and prednisolone immunochemotherapy (R-CHOP21). METHODS: Patients with newly diagnosed de novo DLBCLs treated with ≥1 cycle of R-CHOP21 were analyzed retrospectively. Pretreatment blood samples were collected and the glomerular filtration rate (GFR) was calculated. RI was defined by a GFR of <60 mL/min/1.73 m(2) according to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. RESULTS: Of the 185 patients enrolled in the present study, 19 patients (10.3%) had RI. The reasons for baseline RI were pre-existing CKD (N=5), acute kidney injury due to either obstruction (N=2) or electrolyte imbalance (N=2) related to DLBCL, and undefined causes (N=10). Patients with baseline RI showed inferior overall survival (OS) compared to those without RI (P<0.001). In multivariate analysis, RI was identified as an International Prognostic Index (IPI)-independent prognostic indicator. A baseline hemoglobin level of <10 g/dL and the presence of RI effectively discriminated a portion of the patients with far inferior event-free survival and OS among the patients having high or high-intermediate risk cancers according to either the standard- or the National Comprehensive Cancer Network-IPI. CONCLUSION: Pretreatment RI was an independent prognostic marker for inferior OS in patients with DLBCL treated with R-CHOP21 immunochemotherapy.

PURPOSE: The aim of this study was to verify prognostic factors including sarcopenia in patients with recurrent or metastatic pancreatic cancer receiving gemcitabine-based chemotherapy. MATERIALS AND METHODS: Medical records and computed tomography scan of consecutive patients treated with palliative gemcitabine-based chemotherapy from 2008 to 2014 were reviewed. The lumbar skeletal muscle index at third lumbar spine level was computed, and together with clinicolaboratory factors, univariate and multivariable analyses for overall survival (OS) were performed. RESULTS: A total of 88 patients were found. Median age was 65 years, and male patients were predominant (67.0%). Most patients had initially metastatic disease (72.7%), and gemcitabine monotherapy was administered in 29 patients (33.0%) while gemcitabine plus erlotinib was administered in 59 patients (67.0%). Seventy-six patients (86.3%) had sarcopenia. With a median follow-up period of 44.3 months (range, 0.6 to 44.3 months), median OS was 5.35 months (95% confidence interval [CI], 4.11 to 6.59). In univariate and multivariable analysis, high carcinoembryonic antigen level (hazard ratio [HR], 4.18; 95% CI, 1.95 to 8.97; p < 0.001), initially metastatic disease (HR, 3.37; 95% CI, 1.55 to 7.32; p=0.002), sarcopenia (HR, 2.97; 95% CI, 1.20 to 7.36; p=0.019), neutrophilia (HR, 2.94; 95% CI, 1.27 to 6.79; p=0.012), and high lactate dehydrogenase level (HR, 1.96; 95% CI, 1.07 to 3.58; p=0.029) were identified as independent prognostic factors for OS. CONCLUSION: Five independent prognostic factors in patients with recurrent or metastatic pancreatic cancer who received gemcitabine-based chemotherapy were identified. These findings may be helpful in prediction of prognosis in clinical practice and can be used as a stratification factor for clinical trials.

RESUMEN

BACKGROUND: Neutrophil-lymphocyte count ratio (NLR) is a prognostic factor in cancer, although its prognostic significance in terminally ill cancer patients is not clear. OBJECTIVE: We investigated the association of NLR with survival in patients with terminal cancer. METHODS: We retrospectively investigated 205 consecutive patients with terminal cancer admitted to a palliative care unit during 2014. RESULTS: The median value of NLR was 9.7. In univariable analysis, NLR of 10 or more was significantly associated with shorter survival and NLR further discriminated survival of each palliative prognostic index (PPI) group. In multivariable analysis, increased NLR (≥10) was associated with shorter survival (hazards ratio [HR] 1.54, p<0.005), along with poor performance status (HR 1.55, p < 0.011), high PPI score (HR 1.59, p<0.003), and hyperbilirubinemia (HR 1.84, p < 0.001). CONCLUSION: Our results suggest that elevated NLR was an independent prognostic factor for poor survival in patients with terminal cancer.

RESUMEN

PURPOSE: The purpose of this study is to evaluate the role of C-reactive protein (CRP) and ferritin blood levels in predicting the incidence of systemic infection among adult patients with acute myeloid leukemia (AML) treated with induction chemotherapy. METHODS: Adult patients with newly diagnosed AML who were initially treated with conventional 3 + 7 induction chemotherapy within 5 days of their diagnosis were included. Patients with previous cytotoxic chemotherapy <3 years, acute promyelocytic leukemia diagnosis, human immunodeficiency virus infection, or significant systemic infection at the time of diagnosis were excluded. Patients were treated with an institutional policy of substantial identity with negligible differences regarding supportive care. RESULTS: Among 110 patients (median age 54.5 years), 39 infectious events in 38 patients were reported, along with 21 episodes of infectious treatment-related mortality (TRM; 19.1%). Elevated pre-treatment CRP (p = 0.032) and ferritin (p = 0.002) were related to the incidence of systemic infection. The degree of increase of blood CRP and ferritin level was correlated with the extent of leukocytosis. However, patients with elevated inflammatory markers above normal range had increased risk of infection irrespective of whether they had leukocytosis or not, suggesting that expansion of leukemic blast is another factor affecting the elevation of the markers independent to infection propensity and therefore the magnitude of the elevation does not quantitatively predict the risk of infection. CONCLUSIONS: Modest elevation of baseline blood inflammatory markers above the normal range could be an indicator for predicting the incidence of systemic infection in patients with AML.

RESUMEN

PURPOSE: This study aimed to evaluate the efficacy and safety of pemetrexed versus gefitinib in patients with advanced non-small cell lung cancer (NSCLC) previously treated with chemotherapy. MATERIALS AND METHODS: Patients with advanced (stage IIIB or IV) or recurrent NSCLC were randomly assigned to receive either 500 mg/m² of pemetrexed intravenously every 3 weeks or gefitinib 250 mg/day orally. The primary end point was progression-free survival (PFS) at 6 months. RESULTS: A total of 95 patients were enrolled (47 for pemetrexed and 48 for gefitinib). Most patients were male (72%) and current/ex-smokers (69%), and 80% had non-squamous cell carcinoma. The epidermal growth factor receptor (EGFR) mutation status was determined in 38 patients (40%); one patient per each arm was positive for EGFR mutation. The 6-month PFS rates were 22% and 15% for pemetrexed and gefitinib, respectively (p=0.35). Both arms showed an identical median PFS of 2.0 months and a median overall survival (OS) of 8.5 months. In EGFR wild-type patients, higher response rate (RR) and longer PFS as well as OS were achieved via pemetrexed compared with gefitinib, although there were no significant differences (RR: 39% vs. 9%, p=0.07; median PFS: 6.6 months vs. 3.1 months, p=0.45; median OS: 29.6 months vs. 12.9 months, p=0.62). Toxicities were mild in both treatment arms. Frequently reported toxicities were anemia and fatigue for pemetrexed, and skin rash and anorexia for gefitinib. CONCLUSION: Both pemetrexed and gefitinib had similar efficacy with good tolerability as second-line treatment in unselected patients with advanced NSCLC. However, pemetrexed is considered more effective than gefitinib for EGFR wild-type patients.

RESUMEN

PURPOSE: One of the features in cancer development is the migration of cancer cells to form metastatic lesions. CYR61 protein promotes migration and the epithelial-mesenchymal transition in several cancer cell types. Evidence suggests that CYR61 and dexamethasone are relevant to colorectal cancer. However, relationships between them and colorectal cancer are still unclear. Understanding the molecular mechanism of colorectal cancer progression related with CYR61 and dexamethasone, which is widely used for combination chemotherapy, is necessary for improved therapy. MATERIALS AND METHODS: We used colorectal cancer cells, HCT116, co-treated with transforming growth factor ß1 (TGF-ß1) and dexamethasone to examine the inhibitory migration effect of dexamethasone by migratory assay. Alternatively, both migratory pathways, expression of AKT and ERK, and the target factor CYR61 was also tested by co-treatment with TGF-ß1 and dexamethasone. RESULTS: We report that dexamethasone significantly inhibited TGF-ß1-induced cell migration, without affecting cell proliferation. Importantly, we observed that TGF-ß1 promoted the epithelial-mesenchymal transition process and that dexamethasone co-treatment abolished this effect. ERK and AKT signaling pathways were found to mediate TGF-ß1-induced migration, which was inhibited by dexamethasone. In addition, TGF-ß1 treatment induced CYR61 expression whereas dexamethasone reduced it. These observations were compatible with the modulation of migration observed following treatment of HCT116 cells with human recombinant CYR61 and anti-CYR61 antibody. Our results also indicated that TGF-ß1 enhanced collagen I and reduced matrix metalloproteinase 1 expression, which was reversed by dexamethasone treatment. CONCLUSION: These findings suggested that dexamethasone inhibits AKT and ERK phosphorylation, leading to decreased CYR61 expression, which in turn blocks TGF-ß1-induced migration.

RESUMEN

OBJECTIVES: The purpose of this prospective observational study is to evaluate the relation of the comprehensive geriatric assessment (CGA) to tolerability and survival of multi-agent chemotherapy for curative intent in elderly patients with aggressive non-Hodgkin lymphoma (NHL). MATERIALS AND METHODS: Patients who were 1) age ≥65 years, 2) newly diagnosed aggressive NHL, and 3) treated with multi-agent chemotherapy within 2 weeks from the time of diagnosis were enrolled from January 2011 to June 2014. Baseline clinical, laboratory, and CGA data being composed of Mini Nutritional Assessment-Short Form (MNA-SF), Korean version of Mini Mental Status Exam, Korean-Geriatric Depression Scale, and Groningen Frailty Index (GFI), were collected and analyzed for the relation to the outcome factors. RESULTS: Seventy patients were included; the median age was 73.5 years, 27 (38.6%) patients were Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 2 or more, and half of the patients were high or high-intermediate risk by age-adjusted international prognostic index (aaIPI). Most patients received CHOP or CHOP-like chemotherapy. Factors affecting discontinuation of chemotherapy within 12 weeks were poor MNA-SF, poor GFI, poor PS, and presence of B symptom. Among those, poor MNA-SF was independent of other variables in multivariate analysis. Poor MNA-SF, bone marrow involvement, and baseline anemia of hemoglobin<10g /dL were found to be independent factors associated with inferior overall survival whereas aaIPI factors were not. CONCLUSION: MNA-SF predicted tolerability to multi-agents chemotherapy and overall survival in elderly patients with aggressive NHL who were treated with multi-agent chemotherapy.

RESUMEN

BACKGROUND: Single-agent chemotherapy is considered a good and safe treatment option for elderly patients with advanced gastric cancer (AGC). We investigated the efficacy and safety of trastuzumab plus low-dose capecitabine in elderly patients with previously untreated human epidermal growth factor receptor 2 (HER2)-positive AGC. METHODS: Patients aged 75 years or older with tumors having HER2 overexpression defined as either immunohistochemistry (IHC) 3+ or IHC 2+ and in situ hybridization-positive were eligible for inclusion. Patients received capecitabine (1000 mg/m(2)) orally twice daily on days 1-14 and trastuzumab (8 mg/kg for cycle 1, followed by 6 mg/kg) intravenously on day 1 of a 21-day cycle. The primary endpoint was progression-free survival (PFS). RESULTS: Twenty patients were enrolled. The median age was 79 years (range 75-91). Nine patients (45 %) had ECOG performance status 2. Median PFS was 5.2 months (95 % CI 1.9-8.4 months), and median overall survival was 9.3 months (95 % CI 4.0-14.6 months). The confirmed response rate was 40 % (95 % CI 19-64 %) with disease control rate of 80 %. Grade 3-4 toxicities were anorexia (10 %), fatigue (5 %), stomatitis (5 %), and anemia (5 %). No treatment-related deaths or symptomatic congestive heart failure were observed. CONCLUSIONS: Low-dose capecitabine plus trastuzumab is effective and well tolerated in elderly patients with HER2-positive AGC.

RESUMEN

BACKGROUND: Oraxol consists of paclitaxel and HM30181A, a P-glycoprotein inhibitor, to increase the oral bioavailability of paclitaxel. This phase I/II study (HM-OXL-201) was conducted to determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of Oraxol. In addition, we investigated the efficacy and safety of Oraxol as second-line chemotherapy for metastatic or recurrent gastric cancer (GC). METHODS: In the phase I component, paclitaxel was orally administered at escalating doses (90, 120, or 150 mg/m(2) per day) with a fixed dose (15 mg/day) of HM30181A. Oraxol was administrated 6 times per cycle (days 1, 2, 8, 9, 15, and 16) every 4 weeks. In the phase II component, the efficacy and safety of Oraxol were evaluated. RESULTS: In the phase I component, the MTD could not be determined. Based on toxicity and pharmacokinetic data, the RP2D of oral paclitaxel was determined to be 150 mg/m(2). In the phase II component, 4 of 43 patients (9.3%) achieved partial responses. Median progression-free survival and overall survival were 2.6 and 10.7 months, respectively. Toxicity profiles were favorable, and the most common drug-related adverse events (grade ≥3) were neutropenia and diarrhea. CONCLUSION: Oraxol exhibited modest efficacy and favorable toxicity profiles as second-line chemotherapy for GC.
