ABSTRACT

With the implementation of Act on Hospice and Palliative Care and Decisions on LifeSustaining Treatment for Patients at the End of Life, interests of the general public on selfdetermination right and dignified death of patients have increased markedly in Korea.However, “self-determination” on medical care is misunderstood as decision not to sustain life, and “dignified death” as terminating life before suffering from disease in terminal stage. This belief leads that physician-assisted suicide should be accommodated is being proliferated widely in the society even without accepting euthanasia. Artificially terminating the life of a human is an unethical act even though there is any rational or motivation by the person requesting euthanasia, and there is agreement thereof has been reached while there are overseas countries that allow euthanasia. Given the fact that the essence of medical care is to enable the human to live their lives in greater comfort by enhancing their health throughout their lives, physician-assisted suicide should be deemed as one of the means of euthanasia, not as a means of dignified death. Accordingly, institutional organization and improvement of the quality of hospice palliative care to assist the patients suffering from terminal stage or intractable diseases in putting their lives in order and to more comfortably accept the end of life physically, mentally, socially, psychologically and spiritually need to be implemented first to ensure their dignified death.

ABSTRACT

Extra-pulmonary neuroendocrine carcinoma is a rare and aggressive cancer. Although several biological and histological markers have been suggested as prognostic factors for this cancer, the prognostic importance of systemic inflammatory markers, including the neutrophil-lymphocyte ratio and platelet-lymphocyte ratio, is unclear. This study aimed to evaluate the association between systemic inflammatory markers and the prognosis of extra-pulmonary neuroendocrine carcinoma. We retrospectively analyzed the clinical data of 85 patients with unresectable or metastatic extra-pulmonary neuroendocrine carcinoma who received platinum-based chemotherapy as first-line chemotherapy from August 2007 to November 2019. We used time-dependent receiver operating characteristic curve analysis to determine the cut-off values. The cut-off values for the neutrophil-lymphocyte ratio and platelet-lymphocyte ratio were 3.0 and 158.5, respectively. There was no significant difference in the Eastern Cooperative Oncology Group performance status score, Ki-67 index, or response to chemotherapy between groups. The high neutrophil-lymphocyte ratio group showed significantly worse overall survival (high vs. low, median 11.1 vs. 21.0 months, log-rank p=0.004) and shorter median progression-free survival, but the latter was not statistically significant. The high platelet-lymphocyte ratio group also showed significantly worse progression-free survival and overall survival than the low platelet-lymphocyte ratio group (high vs. low:median 5.6 vs. 9.8 months, log-rank p=0.047 and median 13.8 vs. 21.0 months, log-rank p=0.013, respectively). In multivariable analysis, a high neutrophil-lymphocyte ratio was an independent prognostic factor for overall survival. The neutrophil-lymphocyte ratio is a potent and readily available prognostic factor for extra-pulmonary neuroendocrine carcinoma.

ABSTRACT

As coronavirus disease 2019 (COVID-19) has spread worldwide, the rate of COVID-19 vaccination uptake is encouraging. Neurological complications associated with COVID-19 vaccines such as stroke, Guillain-Barré syndrome, and Bell’s palsy have been reported.Recently, late-onset myasthenia gravis (MG) following COVID-19 vaccination has been reported. To date, however, there has been no evidence of increased risk of early-onset MG following COVID-19. Here, we report a case of a patient with new-onset MG that arose after receiving a COVID-19 vaccine. A 33-year-old woman suddenly experienced generalized weakness and diplopia on the evening she had received the second dose of the PfizerBioNTech COVID-19 vaccine. The temporal relationship suggests that this new-onset MG is related to the vaccination. It also implies that COVID-19 vaccination could trigger early-onset MG symptoms in patients at risk of MG.

ABSTRACT

Purpose@#This study aimed to validate the Sheffield Profile for Assessment and Referral to Care (SPARC) as an effective tool for screening palliative care needs among Korean cancer patients. @*Materials and Methods@#The English version of the SPARC was translated by four Korean oncologists and reconciled by a Korean language specialist and a medical oncologist fluent in English. After the first version of the Korean SPARC (K-SPARC) was developed, back-translation into English was performed by a professional translator and bilingual oncologist. The back-translated version was reviewed by the original author (S.H.A.), and modifications were made (ver. 2). The second version of the K-SPARC was tested against other questionnaires, including the Functional Assessment of Cancer Therapy-General (FACT-G) and the Edmonton Symptom Assessment System (ESAS). @*Results@#Thirty patients were enrolled in the pilot trial. Fifteen were male, and the median age was 64.5 years. Six patients had an Eastern Cooperative Oncology Group performance status of 2 or more. All patients except one were receiving chemotherapy. Regarding internal consistency, the Cronbach’s α scores for physical symptoms, psychological issues, religious and spiritual issues, independency and activity, family and social issues, and treatment issues were 0.812, 0.804, 0.589, 0.843, 0.754, and 0.822, respectively. The correlation coefficients between the SPARC and FACT-G were 0.479 (p=0.007) for the physical domain and –0.130 (p=0.493) for the social domain. @*Conclusion@#This pilot study indicates that the K-SPARC could be a reliable tool to screen for palliative care needs among Korean cancer patients. A further study to validate our findings is ongoing.

ABSTRACT

Neuroendocrine tumors (NETs) are a group of malignancies arising from neuroendocrine cells and frequently originate in the gastrointestinal tract and pancreas. Although curative resection is the main treatment for localized disease, systemic therapy is needed for relapsed or metastatic/unresectable gastroenteropancreatic NETs (GEP-NETs). Although there are several NET treatment guidelines from various countries, the geographical discrepancies between patient clinical characteristics, the regulatory approval status for therapeutic agents, and medical practices necessitate specific guidelines for Korean patients. We here provide a consensus review of the diagnosis, staging and systemic treatment of Korean GEP-NET patients. Systemic therapy options and the current Korean expert consensus on these treatments, including somatostatin analogs, targeted therapies such as everolimus and sunitinib, peptide receptor radionuclide treatments, and cytotoxic chemotherapies are addressed.

ABSTRACT

The clinical outcome in advanced cancer has improved since the development of targeted therapies and immune checkpoint inhibitors. We can expect better overall survival after a combination treatment with these therapeutic agents. Classical cytotoxic chemotherapeutic agents directly kill tumor cells by destroying the cell structure and DNA of tumor cells or inhibiting their metabolism. Targeted therapy also directly affects tumor cells by inhibiting the cell growth signaling system. Conversely, immune checkpoint inhibitors can enhance immune responses by using the host immune system in the tumor microenvironment, leading to the direct killing of tumor cells. Therefore, immune checkpoint inhibitors are less toxic and have longer response durations. Even in solid tumors with nonimmunogenic backgrounds, cytotoxic chemotherapy or targeted treatment can induce immune responses to place the tumor microenvironment in an immunogenic state. Synergistic anticancer effects can be expected when immune checkpoint inhibitors are added during this state. Moreover, drug resistance may be overcome by combination therapies. If patients with cancer are treated with a combination of these therapeutic agents and the characteristics of each tumor are identified with data from next generation sequencing, personalized treatments can be tailored, making it possible to control cancers as a curable disease just like other benign chronic diseases.

ABSTRACT

We reported a 43-year-old male patient who presented with headache and diplopia. The cerebrospinal fluid analysis showed pleocytosis, suggesting acute meningitis. The subsequent polymerase chain reaction and genetic sequencing of blood and cerebrospinal fluid showed that the causative organism was Anaplasma phagocytophilum. This case suggests that we should consider anaplasmosis as a causative agent of acute meningitis; if an unexplained meningitis patient shows no response to any treatments.

ABSTRACT

Background/Aims@#Hyaluronic acid (HA) regulates cell adhesion, migration and proliferation in various cancers. The clinical implications of HA in resected head and neck squamous cell carcinoma have not been elucidated. We investigated the clinical significance and prognostic value of the expression of tumoral and stromal HA and its related proteins in oropharyngeal and oral cavity cancer. @*Methods@#Resected tissues from oropharyngeal or oral cavity cancer patients undergoing surgery were analysed in tissue microarrays divided into stroma and cancer panels. The expression levels of HA, HA synthases and hyaluronidases were also assessed by immunohistochemistry. @*Results@#A total of 160 resected oropharyngeal or oral cavity cancer tissues were analysed. Stromal HA expression was observed more frequently in human papilloma virus (HPV)-negative tumors, but other clinicopathological characteristics did not differ. In patients with HPV-negative oral cavity cancers, high stromal HA expression was associated with significantly shorter recurrence-free survival and overall survival compared with low stromal HA expression. The expression of HA in both tumors and stroma was significantly correlated with poorer outcomes than other combinations in patients with HPV-negative oral cavity cancers. However, these prognostic roles of HA were not observed in patients with HPV-negative oropharyngeal cancers. In the HPV-stratified multivariate analysis, high stromal HA expression remained an independent indicator of poor prognosis in terms of recurrence-free survival. @*Conclusions@#High stromal HA and expression of HA in both tumors and stroma were correlated with poor prognosis in HPV-negative oral cavity cancer, but not in HPV-negative oropharyngeal cancers.

ABSTRACT

Government healthcare expenditure is rising in Korea, and the costs incurred by patients in Korea exceed those incurred by patients in other Organization for Economic Co-operation and Development countries. Despite the increasing health expenditure, patient demand for services is increasing as well, so it is now becoming recognized that cancer care needs to be balanced. The most important measure in cancer care optimization is to provide high-quality care while keeping costs sustainable. The Korean Cancer Association considers the current situation of cancer therapy in Korea the foremost issue, which has led to the implementation of the nationwide ‘Right Decisions in Cancer Care’ initiative. This initiative is based on the concepts of medical professionalism in that it should be led by physicians working in the field of oncology, that education should be offered to patients and clinicians, and that it should influence healthcare policy. In this article, we introduce the nationwide ‘Right Decision in Cancer Care’ initiative and highlight the five initial items on its agenda. The agenda is open to expansion and update as the medical environment evolves and additional clinical evidence becomes available.

ABSTRACT

PURPOSE: A cross-sectional survey was conducted to explore the current awareness and use of complementary and alternative medicine (CAM), as well as attitudes toward CAM, in patients with cancer and their family members in South Korea. MATERIALS AND METHODS: Between September 21 and October 31, 2017, a 25-item questionnaire regarding CAM experiences among cancer patients and their family members was conducted in 10 oncology clinics in South Korea after institutional review board approval at each institution. RESULTS: In total, 283/310 patients were analyzed. The median age was 60 years, and 60% were male. Most of the patients were actively receiving anticancer treatment at the time of the survey. A total of 106 patients (37%) had experienced a median of two types (interquartile range, 1 to 3) of CAM. Belief in CAM (odds ratio [OR], 3.015; 95% confidence interval [CI], 1.611 to 5.640) and duration of disease (OR, 1.012; 95% CI, 1.004 to 1.020) were independent factors for using CAM in multivariable analysis. Belief in CAM was significantly associated with current use of CAM (OR, 3.633; 95% CI, 1.567 to 8.424). Lay referral was the most common reason for deciding to use CAM, and only 25% of patients (72/283) discussed CAM with their physicians. CONCLUSION: Patient attitudes toward and confidence in CAM modalities were strongly associated with their CAM experiences, and only a small number of patients had an open discussion about CAM with their physicians. A patient education program for CAM is needed.

ABSTRACT

PURPOSE: The purpose of this study was to prospectively validate the Korean Cancer Study Group Geriatric Score (KG)-7, a novel geriatric screening tool, in older patients with advanced cancer planned to undergo first-line palliative chemotherapy. MATERIALS AND METHODS: Participants answered the KG-7 questionnaire before undergoing geriatric assessment (GA) and first-line palliative chemotherapy. The performance of KG-7 was evaluated by calculating the sensitivity (SE), specificity (SP), positive and negative predictive value (PPV and NPV), balanced accuracy (BA), and area under the curve (AUC). RESULTS: The baseline GA and KG-7 results were collected from 301 patients. The median age was 75 years (range, 70 to 93 years). Abnormal GA was documented in 222 patients (73.8%). Based on the ≤ 5 cut-off value of KG-7 for abnormal GA, abnormal KG-7 score was shown in 200 patients (66.4%). KG-7 showed SE, SP, PPV, NPV, and BA of 75.7%, 59.7%, 84.4%, 46.0%, and 67.7%, respectively; AUC was 0.745 (95% confidence interval, 0.687 to 0.803). Furthermore, patients with higher KG-7 scores showed significantly longer survival (p=0.006). CONCLUSION: KG-7 appears to be adequate in identifying patients with abnormal GA prospectively. Hence, KG-7 can be a useful screening tool for Asian countries with limited resources and high patient volume.

ABSTRACT

PURPOSE: The signal transducer and activator of transcription 3 (STAT3) signaling pathway might be a promising therapeutic target for hepatocellular carcinoma (HCC). MATERIALS AND METHODS: This study was a multicenter, open-label, non-comparative, dose escalating phase I study of OPB-111077, an oral STAT3 inhibitor, in patients with advanced HCC who failed on sorafenib. Continuous dosing (daily administration, 50 to 400 mg) and intermittent dosing (4-days on/3-days off administration: 300 to 900 mg) regimens were evaluated and the dose-limiting toxicities (DLTs), maximum tolerated dose (MTD), and recommended dose (RD) were the primary endpoints. RESULTS: A total of 33 patients (19 for continuous dosing and 14 for intermittent dosing) were enrolled. One patient experienced a DLT with grade 3 dizziness, but the MTD was identified in neither the continuous nor the intermittent dosing cohorts. The RDs were determined to be 250 mg for the continuous dosing regimen and 600 mg for the intermittent dosing regimen. There was no treatment-related death; five patients (15.2%) had grade 3-4 toxicities including thrombocytopenia (6%), fatigue (3%), and dizziness (3%). No patients achieved complete or partial responses and the median progression-free survival was 1.4 months (95% confidence interval, 0.8 to 2.8). CONCLUSION: OPB-111077 was well tolerated in patients with advanced HCC after sorafenib failure, but only showed limited preliminary efficacy outcomes. Further investigation of the role of the STAT3 signaling pathway in HCC and the development of biomarkers for STAT3 inhibitors are warranted.

ABSTRACT

Hospice and palliative care can help terminal patients and their family members to face the natural end of life more comfortably, by providing them with an environment to address psychosocial and spiritual problems, as well as physical symptoms. However, most patients and their caregivers have the misconception that hospice care means the withdrawal of all treatments. Many physicians also consider hospice care to be a form of terminal care after all treatments are finished. Laws regulating the withdrawal of life-prolonging treatment came into effect in Korea in 2018, and these regulations also apply to most terminal stages of benign diseases. The withdrawal of futile life-prolonging treatment is quite different from euthanasia or negligence. At the last stage of disease, treatment aimed at alleviating various symptoms can make critically ill patients more comfortable and thereby help them to die with dignity. Patients with a terminal illness should receive hospice and palliative care, instead of futile life-prolonging treatment. Therefore, education and training programs to promote a proper understanding of hospice and palliative care should be considered mandatory.

ABSTRACT

BACKGROUND/AIMS@#This study was tried to determine the role of β-catenin in invasion in pancreatic cancer.@*METHODS@#We analyzed cancer invasiveness according to β-catenin expression in pancreatic cancer cell line. We also investigated the change in cancer invasiveness when β-catenin expression was changed. To enhance β-catenin activity, we treated low β-catenin cancer cell line, PANC1, with Wnt-3a conditioned media and transected β-catenin. We also treated high β-catenin expressing cell line, BxPC3, with XAV939, β-catenin inhibitor and siRNA for β-catenin to inhibit β-catenin expression.@*RESULTS@#The high β-catenin expressing cancer cell line, BxPC3 showed higher invasiveness, and low β-catenin expressing cell lines, PANC1and MIA-PaCa-2, were less invasive. By adding the Wnt-3a conditioned media or performing transfection with β-catenin in PANC1, cell invasiveness was increased (p < 0.05 and p < 0.01, respectively). On inhibition of β-catenin by XAV939 and siRNA in BxPC3 cell line, invasiveness was significantly decreased (p < 0.01). It was not correlated with the expression of cluster of differentiation 44 (CD44) or CD44 variant 6 (CD44v6), the invasion related protein. On analysis of association with metastasis in human tissue, Wnt-3a expression was statistically correlated with the development of metastasis (p = 0.029).@*CONCLUSIONS@#Based on our data, β-catenin may be involved in cancer invasion in pancreatic cancer, and it is not associated with CD44, the invasion related protein.

ABSTRACT

BACKGROUND/AIMS: Colorectal cancer is associated with different anatomical, biological, and clinical characteristics. We determined the impact of the primary tumor location in patients with metastatic colorectal cancer (mCRC). METHODS: Demographic data and clinical information were collected from 1,115 patients from the Republic of Korea, who presented with mCRC between January 2009 and December 2011, using web-based electronic case report forms. Associations between the primary tumor location and the patient's clinical characteristics were assessed, and factors inf luencing overall survival were analyzed using Cox proportional hazards regression models. RESULTS: Of the 1,115 patients recruited to the study, 244 (21.9%) had right colon cancer, 483 (43.3%) had left colon cancer, and 388 (34.8%) had rectal cancer. Liver and lung metastases occurred more frequently in patients with left colon and rectal cancer (p = 0.005 and p = 0.006, respectively), while peritoneal and ovarian metastases occurred more frequently in patients with right and left colon cancer (p < 0.001 and p = 0.031, respectively). The median overall survival of patients with tumors originating in the right colon was significantly shorter than that of patients whose tumors had originated in the left colon or rectum (13.7 months [95% confidence interval (CI), 12.0 to 15.5] vs. 18.0 months [95% CI, 16.3 to 19.7] or 19.9 months [95% CI, 18.5 to 21.3], respectively; p = 0.003). Tumor resection, the number of metastatic sites, and primary tumor location correlated with overall survival in the univariate and multivariate analyses. CONCLUSIONS: Primary tumor location influences the metastatic sites and prognosis of patients with mCRC.

ABSTRACT

PURPOSE: The purpose of this study was to investigate the prognostic implications of carcinoembryonic antigen (CEA) levels that are inconsistent with Response Evaluation Criteria in Solid Tumor (RECIST) responses in metastatic colorectal cancer patients. MATERIALS AND METHODS: We retrospectively evaluated 360 patients with at least one measurable lesion who received first-line palliative chemotherapy. CEA-response was defined as CEA-complete response (CR; CEA normalization), CEA-partial response (PR; ≥ 50% decrease in CEA levels), CEA-progressive disease (PD; ≥ 50% increase in CEA levels), and CEA-stable disease (SD; non-CR/PR/PD). Overall survival (OS) and progression-free survival (PFS) were evaluated according to CEA-response. RESULTS: In RECIST-PR patients, poorer CEA-response was associated with disease progression at the subsequent evaluation. In RECIST-SD patients, CEA-CR and -PR were associated with lower disease progression rates than CEA-PD at the subsequent evaluation. Correlations between survival outcome and CEA-response in same-category RECIST patients were assessed. In RECIST-PR patients, discordant CEA-response (CEA-PD/SD) was associated with poorer survival than CEA-CR/PR (median OS and PFS, 44.0 and 15.4 [CEA-CR], 28.9 and 12.5 [CEA-PR], 21.0 and 9.8 [CEA-SD], and 13.0 and 7.0 [CEA-PD] months, respectively; all p < 0.001). In RECIST-SD patients, favorable CEA-response produced better survival (median OS and PFS, 26.8 and 21.0 [CEA-CR], 21.0 and 11.0 [CEA-PR], 16.1 and 8.2 [CEA-SD], and 12.2 and 6.0 [CEA-PD] months, respectively; all p < 0.001). RECIST-PD patients with CEA-CR showed longer OS than those with CEA-PD. Multivariate analysis demonstrated that discordant CEA-response is a powerful prognostic factor for RECIST-PR and RECIST-SD patients. CONCLUSION: Among patients of the same RECIST-response categories, CEA-response patterns are significantly prognostic and strongly predictive of subsequent evaluation outcomes.

ABSTRACT

BACKGROUND/AIMS: Venous thromboembolic events (VTEs) are common events in patients with advanced cancer. We analyzed the clinical characteristics of VTEs in advanced pancreatic and biliary tract cancer to determine the clinical significance, especially in palliative settings. METHODS: Seventy-nine patients with advanced pancreatic cancer or biliary tract cancer who had thromboembolic events were retrospectively reviewed. We investigated the correlation between clinical course and thromboembolic events, and the laboratory risk factors, such as complete blood count profile. RESULTS: The 79 patients consisted of 40 men (50.6%) and 39 women (49.4%) with a median age of 65 years old (range: 41–80). Forty-three patients (54.4%), had thromboembolic events without any symptoms. Pulmonary thromboembolism occurred in only 31 cases (39.2%), and combined thrombosis at more than two sites occurred in 17 cases (21.5%). Of the 51 patients with active chemotherapy, 45 showed progressive disease. The median survival times were 11.9 weeks in all patients, 15.3 weeks in the treatment group, and 3.4 weeks in the palliative group. There was no difference in survival time between patients treated with dalteparin only and those treated with dalteparin combined with thrombolytic intervention. CONCLUSIONS: VTE can be poor prognostic indicator in pancreatic and biliary tract cacner patients, suggestive of progressive disease and a sign of short life expectancy, requiring hospice and terminal care.
