RESUMEN

The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of early and locally-advanced non-small-cell lung cancer (NSCLC) was published in 2017, and covered the diagnosis, staging, management and treatment of both early stage I and II disease and locally-advanced stage III disease. At the ESMO Asia Meeting in November 2018, it was decided by both the ESMO and the Korean Society of Medical Oncology (KSMO) to convene a special face-to-face guidelines meeting in 2019 in Seoul. The aim was to adapt the ESMO 2017 guidelines to take into account potential differences related to ethnicity, cancer biology and standard practices associated with the treatment of locally-advanced, unresectable NSCLC in Asian patients. These guidelines represent the consensus opinions reached by those experts in the treatment of patients with lung cancer who represented the oncology societies of Korea (KSMO), China (CSCO), India (ISMPO), Japan (JSMO), Malaysia (MOS), Singapore (SSO) and Taiwan (TOS). The voting was based on scientific evidence, and it was independent of both local current treatment practices and the treatment availability and reimbursement situations in the individual participating Asian countries.

RESUMEN

AIM: To assess the prognostic value of 2-[18F]-fluoro-2-deoxy-d-glucose (FDG) positron-emission tomography (PET)-based radiomics using a machine learning approach in patients with non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Ninety-three patients with stage I-III NSCLC who underwent combined PET/computed tomography (CT) followed by curative resection. A total of 35 unique quantitative radiomic features was extracted from the PET images, which included imaging phenotypes such as pixel intensity, shape, and texture. Radiomic features were ranked based on score according to their correlation with disease recurrence status within a 3-year follow-up. The recurrence risk classification performances of machine learning algorithms (random forest, neural network, naive Bayes, logistic regression, and support vector machine) using the 20 best-ranked features were compared using the areas under the receiver operating characteristic curve (AUC) and validated by the random sampling method. RESULTS: Contrast and busyness texture features from neighbourhood grey-level difference matrix were found to be the two best predictors of disease recurrence. The random forest model obtained the best performance (AUC: 0.956, accuracy: 0.901, F1 score: 0.872, precision: 0.905, recall: 0.842), followed by the neural network model (AUC: 0.871, accuracy: 0.780, F1 score: 0.708, precision: 0.755, recall: 0.666). CONCLUSION: A PET-based radiomic model was developed and validated for risk classification in NSCLC. The machine learning approach with random forest classifier exhibited good performance in predicting the recurrence risk. Radiomic features may help clinicians to improve the risk stratification for clinical practice.

RESUMEN

To determine the prognostic significance of CT-determined cachexia scores (CSs) in 127 consecutive male small cell lung cancer (SCLC) patients, cross-sectional areas of muscle and fat tissues at the third lumbar vertebra (L3) were retrospectively measured on baseline CT images. CSs were determined based on the presence of sarcopenia and/or adipopenia. According to the presence of sarcopenia (L3 muscle index <55 cm2 /m2 , 86.8%) and adipopenia (L3 fat index <22 cm2 /m2 , 11.8%), CSs were defined as follows: CS2 (sarcopenia and adipopenia, 11.8%), CS1 (sarcopenia only, 74.8%) and CS0 (13.4%). CS2 was significantly related to lower body mass index (p < .001) and poor performance status (p = .002), and patients with CS2 had shorter OS than patients with CS1 or CS0 (median OS, 5.0 months vs. 8.9 months vs. 18.3 months; p = .007). Multivariable analysis revealed that CS was an independent prognostic factor of poor survival (HR, 1.99 for CS1 and 2.59 for CS2, p = .036 and .023, CS0 as a reference), along with extensive stage (p < .001), supportive care only (p < .001) and an elevated lactate dehydrogenase (p = .005). CT-determined CSs, based on the presence of sarcopenia and/or adipopenia, could be used to predict prognosis in male SCLC.

RESUMEN

The present study was designed to investigate if exposure to dried ginger during pregnancy would increase the risk of adverse fetal and neonatal outcomes. Participants consisted of 159 singleton pregnant women who received dried ginger as a herbal medication. We also included a control group of 306 pregnant women who had not been exposed to any herbal medication or any known teratogen. No increased risk of major malformations was detected in exposed women (OR = 4.9; 95% CI 0.9-25.5; p = 0.051). The incidence of stillbirths in the exposed group was marginally higher than in the controls (OR = 7.8; 95% CI 0.9-70.3; p = 0.05). The risk was more evident when the exposed group was compared with the general population in the Republic of Korea (OR = 7.9; 95% CI 2.9-21.4; p < 0.0001). Other fetal and neonatal study outcomes investigated in the exposed group were similar (p > 0.05) to the controls. In conclusion, dried ginger does not appear to be a major teratogen. However, due to the limitations of the study, e.g. the large variability in the dose of dried ginger in the exposed group, as well as the concomitant exposure to other herbal medications, the increased incidence of stillbirths requires confirmation in larger cohort studies.

RESUMEN

Information on the safety of first-trimester exposure to diagnostic magnetic resonance imaging (MRI) remains scarce. We are reporting a case series of 15 consecutive pregnant women who underwent an MRI scan with a 1.5-Tesla scanner of either the head (n = 5), cervical spine (n = 4), lumbar spine (n = 4), pelvis (n = 1) or knee (n = 1) in their first trimester of pregnancy (mean gestational age at exposure: 3.8 weeks). Patients were prospectively followed up until the completion of their pregnancy. Two cases received gadolinium as a contrast agent. There were 15 babies born alive. Of them, one baby was born with the left kidney not visualised by ultrasound examination, and another one with an overlapping toe in the right foot. None of these abnormalities were considered by the authors related to the MRI exposure. In conclusion, our study provides support to published preliminary evidence regarding the safety of MRI in the first-trimester pregnant women.

RESUMEN

BACKGROUND: Treatment options for patients with metastatic gastroenteropancreatic neuroendocrine tumours (GEP NETs) are still limited. We investigated the antitumour activity and safety profile of pazopanib--a multitarget drug with anti-angiogenic activity in patients with metastatic GEP NETs. METHODS: This was a nonrandomised, open-labeled, single-center phase II study. Pazopanib was orally administered at a dose of 800 mg daily continuously with a 28-day cycle. The primary end point was an objective response rate according to Response Evaluation Criteria in Solid Tumors (RECIST). The secondary end points were progression-free survival (PFS), overall survival (OS) and safety. An independent review of objective response was planned. The trial is registered with ClinicalTrials.gov, NCT number 01099540. Correlative biomarker analyses were performed. RESULTS: Between April 2010 and February 2012, a total of 37 patients were enrolled. Thirty-two percent of the enrolled patients had pancreatic primary and 22% of the patients had colorectal primary NETs. This phase II study demonstrated an objective response rate of 18.9% (7 of the 37, 95% CI 8.0-35.2) and a disease control rate (CR+confirmed PR+stable disease) of 75.7% (28 of the 37, 95% CI, 58.8-88.2) in metastatic GEP NETs. The independent review demonstrated a higher overall response rate of 24.3% (95% CI, 11.8-41.2%) with nine confirmed PRs. CONCLUSION: Pazopanib showed a comparable efficacy to other targeted agents not only in pancreatic NETs but also in NETs originating from gastrointestinal (GI) tract.

RESUMEN

BACKGROUND/AIM: Little is known about exposures to low radiation doses in the first trimester of pregnancy and deterministic adverse effects in the offspring, and risks are extrapolated from catastrophic events or from exposures to radiotherapy. The study aimed to assess the foetal and neonatal outcomes of pregnant women exposed to radiodiagnostic procedures with abdominal or lumbar irradiation. METHODS: In a prospective cohort design, we studied the foetal and neonatal outcomes in 115 singleton pregnant women who required abdominal or lumbar radiodiagnostic procedures without the administration of radionucleotides, and in 527 age-matched (± 2 years) control pregnant women. RESULTS: In the exposed group, lumbar spine radiography (33.9%), plain abdominal radiography (16.5%) and upper gastrointestinal tract radiography with abdominal irradiation (15.7%) were the most common radiodiagnostic procedures. Major congenital malformations were identified in two (1.9%) babies born in the exposed group and in two (0.4%) babies born in the control group (odds ratio = 4.7; 95% confidence interval 0.7-33.6; P = 0.15). The rest of the foetal and neonatal outcomes was similar in the two groups except by a marginally higher rate of admissions to the neonatal intensive care unit among babies born to exposed women (odds ratio = 2.9; 95% confidence interval 1.0-9.4; P = 0.06). CONCLUSION: Our results indicate that X-ray and computed tomography scan exposure involving abdominal irradiation without the administration of radionucleotides is not associated with adverse foetal and neonatal deterministic outcomes. Efforts are required to reduce the use of radiodiagnostic procedures for general check-ups in childbearing age women.

RESUMEN

The safety of domperidone in pregnancy remains unknown. Therefore, the study aimed to prospectively evaluate the fetal outcomes of women who were taking domperidone during pregnancy. In a prospective cohort study design, 120 1st- trimester pregnant women who were taking domperidone for controlling gastrointestinal tract symptoms and 212 age-matched pregnant women not exposed to any potential teratogenic agent, were followed-up until delivery. In the case group, domperidone was indicated for control of functional gastrointestinal disorders in 59.2%, the maximum dose was 30 mg/day and exposure occurred between 2(+4) and 20 weeks' gestation. Fetal outcomes including gestational age at birth, birth weight and length, head circumference at birth, and 1- and 5-min Apgar score were similar in the two study groups. There were three babies born with malformations in each group (OR = 0.6; 95% CI 0.1, 2.8). In conclusion, domperidone does not appear to be a major human teratogen. However, our findings require further confirmation in larger studies.

RESUMEN

BACKGROUND: Sasanlimab is an antibody to the programmed cell death protein 1 receptor. We report updated data of subcutaneous sasanlimab in non-small-cell lung cancer (NSCLC) and urothelial carcinoma dose expansion cohorts from a first-in-human phase Ib/II study. PATIENTS AND METHODS: Patients were ≥18 years of age with NSCLC or urothelial carcinoma, and no prior immunotherapies, who progressed on or were intolerant to systemic therapy, or for whom systemic therapy was refused or unavailable. Patients received subcutaneous sasanlimab at 300 mg every 4 weeks (q4w). Primary objectives were to evaluate safety, tolerability, and clinical efficacy by objective response rate (ORR). RESULTS: Sixty-eight and 38 patients with NSCLC and urothelial carcinoma, respectively, received subcutaneous sasanlimab. Overall, sasanlimab was well tolerated; 13.2% of patients experienced grade ≥3 treatment-related adverse events. Confirmed ORR was 16.4% and 18.4% in the NSCLC and urothelial carcinoma cohorts, respectively. ORR was generally higher in patients with high programmed death-ligand 1 (PD-L1) expression (≥25%) and high tumor mutational burden (TMB; >75%). In the NSCLC and urothelial carcinoma cohorts, median progression-free survival (PFS) was 3.7 and 2.9 months, respectively; corresponding median overall survival (OS) was 14.7 and 10.9 months. Overall, longer median PFS and OS correlated with high PD-L1 expression and high TMB. Longer median PFS and OS were also associated with T-cell inflamed gene signature in the urothelial carcinoma cohort. CONCLUSIONS: Subcutaneous sasanlimab at 300 mg q4w was well tolerated with promising clinical efficacy observed. Phase II and III clinical trials of sasanlimab are ongoing to validate clinical benefit. Subcutaneous sasanlimab may be a potential treatment option for patients with NSCLC or urothelial carcinoma.

RESUMEN

The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, staging and treatment of patients with metastatic breast cancer (MBC) was published in 2021. A special, hybrid guidelines meeting was convened by ESMO and the Korean Society of Medical Oncology (KSMO) in collaboration with nine other Asian national oncology societies in May 2022 in order to adapt the ESMO 2021 guidelines to take into account the differences associated with the treatment of MBC in Asia. These guidelines represent the consensus opinions reached by a panel of Asian experts in the treatment of patients with MBC representing the oncological societies of China (CSCO), India (ISMPO), Indonesia (ISHMO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO). The voting was based on the best available scientific evidence and was independent of drug access or practice restrictions in the different Asian countries. The latter were discussed when appropriate. The aim of these guidelines is to provide guidance for the harmonisation of the management of patients with MBC across the different regions of Asia, drawing from data provided by global and Asian trials whilst at the same time integrating the differences in genetics, demographics and scientific evidence, together with restricted access to certain therapeutic strategies.

RESUMEN

BACKGROUND: Clinical features and outcomes of extranodal natural killer/T-cell lymphoma (ENKL) arising from extranasal sites are not fully understood. The purpose of this study was to study the prognosis and treatment outcome of skin/soft tissue primary ENKL. PATIENTS AND METHODS: This multicenter retrospective study included 48 patients with skin/soft tissue primary ENKL diagnosed from 1993 to 2010. RESULTS: Patients with Ann Arbor stage I, T1-2N0M0 by International Society for Cutaneous Lymphomas-European Organization of Research and Treatment of Cancer TNM (tumour-node-metastasis) stage, International prognostic index score of 0-1, and a Korean prognostic index (KPI) score of 0-1 were associated with better survival. Four of five patients with T1-2N0M0 disease achieved complete response with radiation alone. In disseminated disease, only 6 of 13 patients responded to anthracycline-containing chemotherapy, and all the two patients receiving SMILE showed response. CONCLUSION: In conclusion, we identified the prognostic value of KPI, and we suggest a treatment recommendation according to the TNM (tumour-node-metastasis) stage. Radiotherapy with/without chemotherapy seemed to be optimal in localized disease. In advanced stages, a more aggressive treatment regimen with newer agents should be sought.

RESUMEN

BACKGROUND: Recent studies have shown that chemoattractive proteins play an important role in the organization of the innate and adaptive immune responses. There are some reports that chemokine (C-C motif) ligand (CCL)1 and CCL18, members of a family of chemoattractive proteins, have increased expression in atopic dermatitis (AD). AIM: To evaluate the quantity and pattern of CCL1 and CCL18 expression in lesions and blood of patients with AD, and compare them with those of patients with psoriasis. METHODS: Biopsy specimens were taken from atopic skin and normal-appearing skin of patients with AD and from the psoriatic skin only of patients with psoriasis. Quantitative real-time PCR analysis and immunohistochemistry of CCL1 and CCL18 expression were performed, and the quantities of expressed CCL1 and CCL18 in acute AD were compared with those of normal-appearing atopic skin and psoriatic skin. The serum level of CCL1 and CCL18 was assessed by ELISA. RESULTS: Expression of CCL1 mRNA and protein was significantly higher in the acute lesional skin of patients with AD than in their nonlesional skin or in the lesional skin of patients with psoriasis. Both CCL18 mRNA and protein were abundant in acute AD lesions and in psoriatic lesions, but were lower in the nonlesional skin of patients with AD. The serum levels of CCL1 and CCL18 were not different in patients with AD and patients with psoriasis. CONCLUSIONS: CCL1 is a chemokine that is associated with AD. Both CCL1 and CCL18 may play important roles in the initiation and progression of atopic skin inflammation.

RESUMEN

The present study prospectively assessed pregnancy outcome of women taking probiotics during the periconceptional period. A group of 104 women who had taken Lactobacillus in early pregnancy and 200 age- and parity-matched control pregnant women exposed to non-teratogenic agents were also recruited into the study and followed-up prospectively. Median gestational age of women exposed to Lactobacillus was 5.2 (range: 1.9-17.6) weeks. Exposure was at a mean dose of 510 mg/day for a median of 4.0 days (range: 1-90 days). In the exposed group, pregnancy outcomes included 96 live births and eight spontaneous abortions versus 187 live births and 21 spontaneous abortions in the non-exposed group. There was no statistical difference in adverse pregnancy outcomes, including the number of spontaneous abortions, pre-term births as well as a low birth weight between the two groups (p > 0.05). In the exposed group, there were two (2.1%) major congenital malformations in comparison with five (2.7%) in the comparison group (p = 0.7). In conclusion, no association was identified between ingestion of Lactobacillus in early pregnancy for a limited period of time and adverse pregnancy outcomes. However, rare pregnancy outcomes may have been missed due to the limited sample size included in the study.

RESUMEN

Despite barium being used as a contrast media for decades, the specific assessment of its safety in pregnant women is scarce. We are reporting the favourable pregnancy outcome in women who were inadvertently exposed to barium swallow and associated ionising radiation, early in pregnancy. A control group of age- and gravidity-matched unexposed pregnant women was also included. There were 32 live-born babies in the exposed group and 94 in the control group. Women had undergone diagnostic upper gastrointestinal tract (UGT) fluoroscopic examination at 3.3 ± 1.5 weeks' gestation. Estimated maternal radiation dose secondary to barium swallow varied widely, the maximum dose was estimated to be 2.45 mSv. Similar pregnancy outcomes were observed between the groups. The number of babies born with major malformations was not significantly different (p = 1.0) between cases and controls: one (3.1%) vs three (3.2%), respectively. In conclusion, our small prospective cohort study of women suggests no association between inadvertent exposure to ionising radiation and barium sulphate during fluoroscopic barium swallow and adverse fetal outcomes.

RESUMEN

X-ray exposure, especially if directed to the abdominal region, is of major concern for pregnant women and their physicians. In this study, favourable long-term outcomes are reported in a series of babies born to women inadvertently exposed to barium enema, and associated ionising radiation, early in pregnancy. Six singleton babies were vaginally delivered without any evidence of gross malformations. There was one voluntary abortion. Follow-up on five of the babies was performed over the course of at least 4 years. All the children were deemed healthy and had developed milestones according to their age. Our findings support larger studies suggesting barium enema is not a teratogenic agent. Collectively, this research can be used to counsel women undergoing radiological procedures early in pregnancy.

RESUMEN

No information is currently available on the safety of methylephedrine, a component of various cold medications available in South Korea. With previous approval by an Institutional Review Board, 349 women inadvertently exposed to methylephedrine during the 1st trimester of pregnancy and an age- and gravidity-matched control group, were enrolled in a prospective cohort study. Study outcomes, for example gestational age at birth, birth weight and major and minor malformations were evaluated in 282 cases and 280 controls. Exposure to methylephedrine was at a gestational age of 4.0 weeks (median), at doses ranging from 52.5 to 1,575 mg/day, for a median duration of 3 (range: 1-30) days. No differences were observed between cases and controls in any of the pregnancy outcomes studied. There were 4/265 (1.5%) babies born with major malformations in the case group and 4/260 (1.5%) in the control group. In conclusion, inadvertent exposure to methylephedrine as a component of over-the counter oral cold remedies in early pregnancy was not associated with an increased rate of adverse pregnancy outcomes. Co-exposure with acetaminophen, cigarette smoking or alcohol did not appear to modify the outcomes.

RESUMEN

To evaluate whether periconceptional exposure to oral contraceptives (OCs) increased adverse pregnancy outcomes, 136 pregnant women taking OCs within the periconceptional period were identified at the Korean Motherisk Program. Of them, 120 pregnant women accepted to participate in their study and were followed up until completion of the pregnancy. A control group of 240 age- and gravidity-matched pregnant women exposed to non-teratogen drugs for at least 1 month before pregnancy was also included. The median gestational age at delivery was 39.1 (27.0-41.0) weeks in the exposed group and 39.3 (27.4-42.0) weeks in the control group (P = 0.19). In the exposed group, 7.1% of babies were born with low birth weight versus 2.6% in the control group (P = 0.068). The number of preterm deliveries or babies born large for gestational age did not differ between the two groups. In the exposed group, the rate of birth defects was 3.2% (n = 3/99) versus 3.6% (n = 7/193) in the control group (P = 1.0). There were 15 women who took high doses of progesterone (emergency contraception) and no adverse fetal outcomes were observed. In conclusion, periconceptional exposure to OCs does not appear to increase the risk for adverse pregnancy outcomes.

RESUMEN

Moisture affects the physical and biological properties of compost and other solid-state fermentation matrices. Aerobic microbial systems experience different respiration rates (oxygen uptake and CO2 evolution) as a function of moisture content and material type. In this study the microbial respiration rates of 12 mortality composting envelope materials were measured by a pressure sensor method at six different moisture levels. A wide range of respiration (1.6-94.2mg O2/g VS-day) rates were observed for different materials, with alfalfa hay, silage, oat straw, and turkey litter having the highest values. These four envelope materials may be particularly suitable for improving internal temperature and pathogen destruction rates for disease-related mortality composting. Optimum moisture content was determined based on measurements across a range that spans the maximum respiration rate. The optimum moisture content of each material was observed near water holding capacity, which ranged from near 60% to over 80% on a wet basis for all materials except a highly stabilized soil compost blend (optimum around 25% w.b.). The implications of the results for moisture management and process control strategies during mortality composting are discussed.

RESUMEN

Physical parameters of 12 co-compost cover materials were experimentally determined and predicted variations in airflow characteristics were evaluated under varying moisture contents. Predicted air-filled porosity showed high correlation with measured air-filled porosity, facilitating development of a reliable model of air-filled porosity that makes it possible to predict the effect of varying moisture content and compost bed height on air-filled porosity and permeability. Predicted air-filled porosity decreased with increasing moisture content and compost depth for all materials. Air-filled porosity of corn stalks, oat straw, soybean straw, leaves, alfalfa hay, wheat straw, silage, wood shavings and sawdust was in the range of 38-99%. Turkey litter, soil compost blend and beef manure showed air-filled porosity values less than 30% near saturation and the bottom of pile. In concert with the findings of other researchers, effective particle size of all materials increased with increasing moisture content from 20% to 80% of water holding capacity (WHC). It increased dramatically near saturation. In general, permeability increased with increasing air-filled porosity and decreasing bulk density, but the relationship between permeability and moisture content is complex. Permeability is dependent on the balance between particle size and air-filled porosity. If the influence of aggregated particle size on the permeability is significant, it will compensate for the effect of reduced air-filled porosity caused by compaction and moisture content. In this case, permeability will increase; in the reverse case, it will decrease. Permeability decreased for corn stalks, oat straw, silage, wood shavings, soybean straw, sawdust, turkey litter and wheat straw with increasing moisture content from 20% WHC to 50% WHC, regardless of the depth of the compost bed. But the permeability increased with increasing moisture level from 50% to 80% WHC at moderate to shallow simulated bed depths. The soil compost blend and leaves showed the permeability increasing when the moisture increased not only from 50% to 80% WHC but also from 20% to 50% WHC. Permeability of alfalfa hay and beef manure always decreased with increasing moisture levels and pile depth. In this study the maximum wet bulk density and mechanical strength decreased with increasing the moisture content. The method described for determining physical properties under varying moisture contents and compost bed depths will be very useful for designing and modeling airflow characteristics of a mortality composting process with a variety of materials.

RESUMEN

Several studies have reported an association between depression and folic acid deficiency. We investigated whether intake of prenatal multivitamins containing folic acid (MVandFA) was associated with decreased rates of depression among pregnant women. A questionnaire was given to 1,314 low-risk pregnant women. Of them, 1,277 (97.2%) women completed the questionnaire. The overall prevalence of depression was 8.1%. Of 652 participants who did not take MVandFA, 9.4% had depression, whereas 6.9% of 624 women who had MVandFA had depression (p = 0.11). In a multivariate logistic regression analysis, family history of depression (adjusted OR 3.7; 95% CI 1.9-7.3) and premenstrual syndrome (adjusted OR 3.0, 95% CI 1.8-4.8) were identified as risk factors for depression during pregnancy. In conclusion, intake of MVandFA was not associated with lower rates of depression during pregnancy whereas family history of depression and personal history of premenstrual syndrome were significant risk factors.
