RESUMEN

BACKGROUND: Ramucirumab improves survival in gastric cancer patients. The efficacy and safety of ramucirumab outside of a clinical trial were evaluated using an expanded access program (EAP). METHODS: Advanced gastric cancer patients treated with ramucirumab in combination with paclitaxel or with ramucirumab monotherapy in a Korean EAP were evaluated. Baseline characteristics were assessed for progression-free survival (PFS) and overall survival (OS), and adverse events were evaluated according to the treatment regimen. RESULTS: Of 265 patients, 228 received ramucirumab plus paclitaxel, and 37 received ramucirumab monotherapy. Grade 3 or 4 neutropenia was more common with ramucirumab plus paclitaxel than with ramucirumab monotherapy (46.7 vs. 8.1%). Gastrointestinal (GI) perforation developed in seven patients (3.1%) in the ramucirumab plus paclitaxel group. The overall response and disease control rates were 16.6 and 66.3% in the ramucirumab plus paclitaxel group, and 5.4 and 37.8% in the ramucirumab monotherapy group, respectively. PFS and OS were 3.8 and 8.6 months in the ramucirumab plus paclitaxel group, and 1.8 and 6.4 months in the ramucirumab monotherapy group, respectively. In multivariate analysis, alkaline phosphatase, albumin, and neutrophil-to-lymphocyte ratio (NLR) were the independent prognostic factors for PFS, while albumin, NLR, number of metastatic sites, and large amount of ascites were independent prognostic factors for OS. CONCLUSION: In the Korean EAP cohort, ramucirumab showed similar efficacy to the results of the previous trials for gastric cancer. However, the level of GI perforation was slightly increased in the ramucirumab plus paclitaxel group.

RESUMEN

PURPOSE: The objective of this study was to investigate the impact of caregivers' role preference in decision making on conflicts and psychiatric distresses. METHODS: The responses of 406 caregivers of terminal cancer patients enrolled in a trial determining the efficacy of a decision aid focused on the disclosure of terminal disease status were included in this secondary analysis. The outcomes include the change scores of the Decision Conflict Scale (DCS) and depression and anxiety subscales of the Hospital Anxiety and Depression Scale (HADS) at the 1 and 3 months from baseline. The linear mixed model was employed to discover the impact of caregivers' decisional role preference on the outcomes. FINDINGS: Of the 406, 137 (33.7%) showed an active role preference and 269 (66.3%) showed a passive role preference. In the post hoc analysis of the adjusted differences of change scores between passive caregivers who received decision aid (passive-decision aid) and active caregivers with decision aid (active-decision aid), non-significant differences were observed in the DCS. However, at the 3-month, the change scores of the HADS depression subscale increased by 4.43 (effect size, 0.71) and those of the HADS anxiety subscale increased by 4.14 (effect size, 0.61) in the passive-decision aid group than in active-decision aid group, showing moderate to large difference. CONCLUSIONS: These findings suggest that information might be ethically recommended in a format that is interactive and tailored to how much an individual wishes to be involved in the decision-making process.

RESUMEN

PURPOSE: Neuropathic cancer pain (NCP) is a common and potentially debilitating symptom in cancer patients. We investigated the prevalence of NCP, as well as its management and association with QOL. METHODS: Cancer patients with pain ≥1 on the visual analogue scale (VAS) were surveyed with the Douleur Neuropathique (DN4) questionnaire, the Brief Pain Inventory-Short Form (BPI-SF), and the EuroQOL five dimensions (EQ-5D) questionnaire. The associations between NCP and pain severity or NCP and QOL, while controlling for variables relevant to QOL, were then analyzed. RESULTS: A total of 2003 patients were enrolled in this survey; the prevalence of NCP was 36.0% (n = 722, 95% CI, 32.5-39.5). We found that NCP in cancer patients was closely correlated to a higher pain severity (BPI-SF; 4.96 ± 1.94 versus 4.24 ± 2.02, p < 0.001), and in patients with NCP, pain more severely interfered with daily living, as compared to those without NCP (BPI-SF; 4.86 ± 2.71 versus 4.41 ± 2.87, p < 0.001). Patients with NCP also had worse QOL than those without NCP, as measured by EQ-5D index score (0.47 ± 0.30 vs. 0.51 ± 0.30, p = 0.005), and this was confirmed using multivariate analysis (p < 0.001), even after controlling for other variables such as age, sex, disease stage, cancer duration, radiotherapy, chemotherapy, and comorbidities. Importantly, adjuvant analgesics were used in less than half of patients with NCP (n = 358, 46.4%). CONCLUSIONS: We found that NCP in cancer patients was significantly associated with a worsened QOL, and current management is inadequate. Therefore, future research aimed at developing improved strategies for management of NCP is required.

RESUMEN

Extranodal NK/T-cell lymphoma (ENKTCL) is associated with latent Epstein-Barr virus (EBV) infection and frequent relapse even after complete response (CR) to intensive chemotherapy and radiotherapy. The expression of EBV proteins in the tumor provides targets for adoptive immunotherapy with antigen-specific cytotoxic T cells (CTL). To evaluate the efficacy and safety of EBV latent membrane protein (LMP)-1 and LMP-2a-specific CTLs (LMP1/2a CTLs) stimulated with LMP1/2a RNA-transferred dendritic cells, we treated 10 ENKTCL patients who showed complete response to induction therapy. Patients who completed and responded to chemotherapy, radiotherapy, and/or high-dose therapy followed by stem cell transplantation (HDT/SCT) were eligible to receive eight doses of 2 × 10(7) LMP1/2a CTLs/m(2). Following infusion, there were no immediate or delayed toxicities. The 4-year overall survival (OS) and progression-free survival (PFS) were 100%, and 90% (95% CI: 71.4 to 100%) respectively with a median follow-up of 55·5 months. Circulating IFN-γ secreting LMP1 and LMP2a-specific T cells within the peripheral blood corresponded with decline in plasma EBV DNA levels in patients. Adoptive transfer of LMP1/2a CTLs in ENKTCL patients is a safe and effective postremission therapeutic approach. Further randomized studies will be needed to define the role of EBV-CTLs in preventing relapse of ENKTCL.

RESUMEN

BACKGROUND: Palliative chemotherapy is used to prolong survival among elderly patients with inoperable gastric cancer (GC). We analyzed differences between single and combination first-line palliative chemotherapy among these patients. METHODS: Included patients were >70 years old and were treated for GC at four clinical centers of the Catholic University of Korea. Baseline characteristics, the first-line chemotherapy regimen, treatment responses, toxicities, progression-free survival (PFS), and overall survival (OS) were evaluated. RESULTS: Between 2005 and 2012, 178 > 70-year-old patients with GC received palliative chemotherapy using single or combination regimens. Median ages were 77 years (range 71-89) in the single regimen group (SG, 70 patients) and 73 years (range 71-81) in the combination group (CG, 108 patients). Patients in the SG received S-1 or capecitabine. The most common regimen in the CG was platinum combined with fluorouracil. The most common response in both groups was stable disease (SG, 45.7 %; CG, 48.1 %). In the SG and CG, median PFS times were 4.4 months (95 % confidence interval [CI] 2.85-5.95) and 4.1 months (95 % CI 2.62-5.57; P = 0.295), respectively; median OS times were 6.6 months (95 % CI 4.17-9.08) and 7.6 months (95 % CI 5.50-9.69; P = 0.782), respectively. Hematologic (P < 0.001) and non-hematologic toxicities (P < 0.001) were more frequent in the CG. The most common causes of chemotherapy cessation were disease progression in the SG and decreased performance status in the CG. CONCLUSIONS: Single-agent treatment should be considered a first-line palliative chemotherapy option for elderly patients with GC.

RESUMEN

BACKGROUND: Few studies of systemic chemotherapy have focused on gastric cancer with peritoneal carcinomatosis (PC) without measurable lesions. In the present study, we characterized the outcomes of systemic chemotherapy and prognostic factors for gastric cancer with PC, particularly in patients without measurable disease. METHODS: Clinical data from 211 gastric cancer patients with PC (137 without and 74 with measurable disease) who had received systemic chemotherapy between January 2003 and December 2010 at a single center were reviewed. RESULTS: The median overall survival (OS) rate of gastric cancer patients with PC with no measurable disease was significantly longer than that of patients with measurable disease (18.0 vs. 11.6 months, p = 0.010). On multivariate analysis, poor performance status [hazard ratio (HR) = 2.15, p < 0.001], the presence of metastatic lymphadenopathy (HR = 2.17, p < 0.001), and high-grade PC (HR = 1.83, p = 0.001) were associated with significantly decreased OS. When patients with low-grade PC were stratified by clinical PC grade, the median OS of those without measurable disease was 19.6 months. The median OS of patients with low-grade PC with no measurable disease was longer than those of patients with high-grade PC without measurable disease, patients with low-grade PC with measurable disease, and patients with high-grade PC with measurable disease (p = 0.001, p = 0.029, and p < 0.001, respectively). Among the patients with low-grade PC, patients who received a gastrectomy had longer survival than patients who did not receive a gastrectomy (p < 0.001). CONCLUSIONS: In our study, clinically low-grade PC without measurable disease was associated with better outcomes of systemic chemotherapy than the outcomes in the other groups examined. Clinical trials in patients with gastric cancer with PC should be stratified according to PC grade.

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

BACKGROUND: CD44s is a cell adhesion molecule known to mediate cellular adhesion to the extracellular matrix, a prerequisite for tumor cell migration. CD44s plays an important role in invasion and metastasis of various cancers. In the present study, we sought to determine whether CD44s is involved in clinical outcomes of patients with resected non-small cell lung cancer (NSCLC). METHODS: Using immunohistochemical staining, we investigated CD44s protein expression using tissue array specimens from 159 patients with resected NSCLC (adenocarcinoma (AC; n=82) and squamous cell carcinoma (SCC; n=77). Additionally, the immunoreactivity of cyclooxygenase (COX)-2 was also studied. The clinicopathological implications of these molecules were analyzed statistically. RESULTS: High CD44s expression was detected more frequently in NSCLC patients with SCC (66/72; 91.7%) than in those with AC histology (P<0.001). Additionally, high CD44s expression was significant correlated with more advanced regional lymph node metastasis (P=0.021). In multivariate analysis of survival in NSCLC patients with AC histology, significant predictors were lymph node metastasis status (P<0.001), high-grade tumor differentiation (P=0.046), and high CD44s expression (P=0.014). For NSCLC patients with SCC histology, the significant predictor was a more advanced tumor stage (P=0.015). No significant association was found between CD44s and clinical outcome (P=0.311). CONCLUSIONS: High CD44s expression was a negative prognostic marker with significance in patients with resected NSCLC, particularly those with AC histology, and was independent of tumor stage.

RESUMEN

The World Health Organization (WHO) declared the coronavirus disease 2019 (COVID-19) outbreak to be a pandemic on March 12, 2020. In Korea, there have been 24,027 confirmed cases of COVID-19 and 420 deaths as of October 3, 2020. The clinical spectrum of COVID-19 ranges from asymptomatic infection to death. Cancer care in this pandemic has radically changed. The literature was reviewed. The COVID-19 pandemic has made it urgently necessary to profoundly re-organize cancer patients' care without compromising cancer outcomes. Several important questions in regard to COVID-19 infection in cancer patients have emerged. Are patients with cancer at a higher risk of COVID-19 infection? Are they at an increased risk of mortality and severe illness when infected with COVID-19? Does anticancer treatment affect the course of COVID-19? Based on the existing research, cancer patients with immunosuppression are vulnerable to COVID-19 infection, and cancer patients are more likely to experience severe COVID-19. However, chemotherapy and major surgery do not seem to be predictors of hospitalization or severe disease. Korean background data on patients with cancer and COVID-19 are lacking. Prospective multicenter studies on the outcomes of patients with cancer and COVID-19 should be conducted.

RESUMEN

Collagen XVIII is a component of vascular and epithelial basement membranes. The C-terminal fragment of the protein is termed endostatin, and is a potent inhibitor of angiogenesis. No reports on the clinical implications of collagen XVIII expression in human gastric cancer are currently available. Here, we investigate the clinical significance of collagen XVIII expression in gastric cancer. Seven gastric cancer cell lines were subjected to Western blotting. Collagen XVIII expression was examined in 118 gastric carcinoma tissues via immunohistochemistry. Western blotting revealed the presence of the 22-kDa collagen XVIII protein in four of seven gastric cancer cell lines. Immunohistochemistry detected collagen XVIII expression in the tumor cytoplasm in 115 of 118 gastric carcinoma patients (97%). No correlation was evident between collagen XVIII expression score and clinicopathologic findings when all patients were considered together. However, on subgroup analysis, 42 of 70 patients with distant metastasis were classified into low or moderate collagen XVIII expression groups, whereas the remaining 28 patients were grouped as showing high collagen XVIII expression. The prognosis for patients with high collagen XVIII-expressing gastric carcinoma was significantly worse than that for patients displaying low or moderate collagen XVIII expression (median survival time, 7.8 months vs. 18.3 months [log-rank, p = 0.01]; median time to progression, 3 months vs. 8 months [log-rank, p = 0.01]). High expression of collagen XVIII is associated with poor prognosis in patients with metastatic gastric carcinoma. Further studies on larger patient populations are warranted to validate the utility of collagen XVIII as a prognostic biomarker in gastric carcinoma.

RESUMEN

Four types of human hyaluronidases (rHuHyal-1, -2, -3 and -4) were transiently expressed and purified from Nicotiana benthamiana, and their biochemical characteristics were analyzed. The recombinant HuHyals were expressed via agrobacteria-mediated infiltration and generated and expressed in terms of micrograms per 5 leaves of N. benthamiana. Expressed recombinant HuHyals were purified using a His(6) tagging system and Ni column chromatography, respectively, at pH 8.0, after which the purified rHuHyals were concentrated for additional biochemical analyses. The four types of rHuHyals were allowed to react with hyaluronic acids and chondroitin sulfates. The biochemical properties of rHuHyal-1 fit those of the commercially available Hyal, PH-20, which was extracted from animal testes under acidic conditions (pH 3.5). However, rHuHyal-1 evidenced activity levels 2 to 6-fold greater than the three other rHuHyals (rHuHyal-2, -3 and -4) at pH 3.5. However, only rHuHyal-4 exhibited chondroitinase activity with both 6-S-chondroitin sulfate (chondroitin sulfate C) and 4-S-chondroitin sulfate (chondroitin sulfate A) as standard substrates. The results of zymography demonstrated that recombinant HuHyal 1 was modified by glycosylation, but Escherichia coli Hyal was not. This result demonstrated that plant-based rHuHyal was functionally active and evidenced biochemical characteristics and post-translational protein modifications similar to those of animal testis-derived Hyal.

RESUMEN

GOALS OF WORK: The goal of this study was to investigate the utilization of and attitudes toward life-sustaining treatments (LSTs) at the end of life. MATERIALS AND METHODS: We identified 4,042 families of cancer patients who had died at any of 17 hospitals in Korea during 2004. Among those, we analyzed the interviews provided by 1,592 (39.4%) primary caregivers. Only women who provided information in baseline and follow-up point could be included for internal comparison. MAIN RESULTS: Most caregivers did not discuss with their patient the option of utilizing the intensive care unit (ICU; 92.7%) or cardiopulmonary resuscitation (CPR; 93.7%) to prolong an ending life. Logistic regressions indicated that the ICU was more likely to be utilized when patients experienced an unexpected medical problem before dying, discussed the ICU with the family caregiver, or were low-educated. CPR was more likely to be used if the patient died within 6 months of diagnosis or the family caregiver was <65 years old. Family caregivers more likely to use the ICU if placed in the same situation again were those whose patients had a higher monthly income or died within 6 months of diagnosis, low-educated, or had utilized the ICU. CONCLUSIONS: Our findings underscore the importance of discussing LST with terminally ill patients based on adequate information.

RESUMEN

GOALS OF WORK: Family caregivers play an important role in caring for cancer patients, but the impact of caregivers' unmet needs on the quality of end-of-life (EOL) care they deliver and on their workplace performance are less understood. PATIENTS AND METHODS: We identified 1,662 family caregivers of cancer patients who had died at any of 17 hospitals in Korea during 2004. The caregivers answered a telephone questionnaire about needs that were not met when they delivered terminal cancer care and how those unmet their needs affected their workplace performance; they also answered the Quality Care Questionnaire-End of Life (QCQ-EOL). RESULTS: Compared with caregivers who did not have unmet needs, caregivers who had unmet needs for symptom management, financial support, or community support showed poorer QCQ-EOL scores (P < 0.01). Caregivers who had unmet needs for financial support (adjusted odds ratio (aOR) = 7.55; 95% confidential interval (CI) 3.80-15.00), psychosocial support (aOR = 6.24; 95% CI 2.95-13.05), symptom management (aOR = 3.21; 95% CI 2.26-4.54), community support (aOR = 3.82; 95% CI 2.38-6.11), or religious support (aOR = 4.55; 95% CI 1.84-11.26) were more likely to experience work limitations. Caregivers of patients receiving conventional hospital care were more likely to have unmet needs for symptom management (aOR = 1.21; 95% CI 1.00-1.47), psychosocial support (aOR = 1.99; 95% CI 1.37-2.88), and religious support (aOR = 1.73; 95% CI 1.08-2.78) than those of patients receiving palliative hospice care. CONCLUSIONS: Caregivers' unmet needs negatively affected both the quality of EOL care they delivered and their workplace performance. More investment in caregiver support and public policies that meet caregiver needs are needed, and hospice use should be encouraged.

RESUMEN

To test the carcinostatic effects of ascorbic acid, we challenged the mice of seven experimental groups with 1.7 x 10(-4) mol high dose concentration ascorbic acid after intraperitoneal administrating them with sarcoma S-180 cells. The survival rate was increased by 20% in the group that received high dose concentration ascorbic acid, compared to the control. The highest survival rate was observed in the group in which 1.7 x 10(-4) mol ascorbic acid had been continuously injected before and after the induction of cancer cells, rather than just after the induction of cancer cells. The expression of three angiogenesis-related genes was inhibited by 0.3 times in bFGF, 7 times in VEGF and 4 times in MMP2 of the groups with higher survival rates. Biopsy Results, gene expression studies, and wound healing analysis in vivo and in vitro suggested that the carcinostatic effect induced by high dose concentration ascorbic acid occurred through inhibition of angiogenesis.

RESUMEN

PURPOSE: The purpose of this study was to evaluate chemotherapy patterns and changes in quality of life (QOL) during first-line palliative chemotherapy for Korean patients with unresectable or metastatic/recurrent gastric cancer (GC). MATERIALS AND METHODS: Thiswas a non-interventional, multi-center, prospective, observational study of 527 patients in Korea. QOL assessments were conducted using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaires (QLQ)-C30 and QLQ-STO22 every 3 months over a 12-month period during first-line palliative chemotherapy. The specific chemotherapy regimens were selected by individual clinicians. RESULTS: Most patients (93.2%) received combination chemotherapy (mainly fluoropyrimidine plus platinum) as their first-line palliative chemotherapy. The median progression-free survival and overall survival were 8.2 and 14.8 months, respectively. Overall, "a little" changes (differences of 5-10 points from baseline)were observed in some of the functioning or symptom scales; none of the QOL scales showed either "moderate" or "very much" change (i.e., ≥ 11 point difference from baseline). When examining the best change in each QOL domain from baseline, scales related to some aspects of functioning, global health status/QOL, and most symptoms revealed significant improvements (p < 0.05). Throughout the course of first-line palliative chemotherapy, most patients' QOL was maintained to a similar degree, regardless of their actual response to chemotherapy. CONCLUSION: This observational study provides important information on the chemotherapy patterns and QOL changes in Korean patientswith advanced GC. Overall, first-line palliative chemotherapy was found to maintain QOL, and most parameters showed an improvement compared with the baseline at some point during the course.

RESUMEN

Primary adenocarcinoma of the appendix is a rare malignancy that constitutes < 0.5% of all gastrointestinal neoplasms. Moreover, primary signet ring cell carcinoma of the appendix is an exceedingly rare entity. We have encountered 15 cases of primary appendiceal cancer among 3389 patients who underwent appendectomy over the past 18 years. In the present report, we describe a rare case of primary signet ring cell carcinoma of the appendix with ovarian metastases and unresectable peritoneal dissemination occurring in a 67-year-old female patient. She underwent appendectomy and bilateral salpingo-oophorectomy with a laparoscopy procedure. She then received palliative systemic chemotherapy with 12 cycles of oxaliplatin, 5-flurorouracil, and leucovorin (FOLFOX-4). The patient currently is well without progression of disease 12 mo after beginning chemotherapy.

RESUMEN

OBJECTIVES: We investigated the frequency of chemotherapy use and its associated factors in patients in all age groups in the last year of life. METHODS: We identified cancer patients who died in 2004 in any of 17 hospitals. We used demographic and treatment characteristics by computerized hospital information systems and by linking the identification numbers to the 2004 death registry. RESULTS: 48.7% of patients in the last 6 months of life, 43.9% in the last 3 months, and 30.9% in the last month of life received chemotherapy. The frequency of chemotherapy use was lower for older patients. In those > or =65 years old, there was no difference between women and men in the proportion that received chemotherapy. For patients <65 years of age, a larger proportion of women than men received chemotherapy, and chemotherapy use was significantly less frequent for patients with refractory disease than for those with responsive disease. Patients dying at a relatively small hospital without a hospice inpatient unit were significantly more likely to receive chemotherapy. CONCLUSIONS: Despite the fact that most cancer patients are resistant to chemotherapy at the end of life, it was administered often to all age groups.

RESUMEN

Angiocentric lymphoma, known as natural killer (NK)/T-cell non-Hodgkin's lymphoma, has been reported to be associated with the Epstein-Barr virus (EBV). We performed adoptive transfer of EBV-specific polyclonal T-cell lines in 3 patients with extranodal NK/T-cell lymphoma, nasal type, and evaluated the treatment for safety, immunologic reconstitution, and clinical outcomes. The tissue samples collected from the 3 patients were confirmed by polymerase chain reaction analysis to be EBV positive. In the cases of the first and second patients, EBV-transformed B-lymphoblastoid cell lines (LCLs) and T-cell lines were generated from peripheral lymphocytes of HLA-matched sibling donors. The third patient's T-cell lines were induced with autologous lymphocytes. Polyclonal T-cell infusion was carried out after high-dose radiotherapy because active relapsed disease remained in all of the patients. The first patient received 4 weekly infusions of 2 3 10(7) cells/m(2), and the second and third patients underwent treatment with 2 cycles of infusions of the same dosage. All T-cell lines showed >60% NK activity, cytotoxic T-lymphocyte (CTL) responses of >40% against autologous LCLs, and no CTL activity against patient-derived lymphoblasts. The level of cytotoxicity increased substantially in all patients after cell infusion. The 2 patients who received T-cell therapy twice had stabilized disease for more than 3 years. These safe treatments exhibited no severe inflammatory response, and no serious toxicity developed during T-cell therapy. Our findings demonstrate that adoptively transferred cells may provide reconstitution of EBV-specific CTL responses in patients with active relapsed angiocentric lymphoma. These results provide a rationale for the immunotherapy of angiocentric lymphoma.

RESUMEN

PURPOSE: To ascertain the attitude of cancer patients and their families toward disclosure of terminal illness to the patient. PATIENTS AND METHODS: We constructed a questionnaire that included demographic and clinical information and delivered it to 758 consecutive individuals (433 cancer patients and 325 families that have a relative with cancer) at seven university hospitals and one national cancer center in Korea. RESULTS: 380 cancer patients and one member from each of 281 families that have a relative with cancer completed the questionnaire. Cancer patients were more likely than family members to believe that patients should be informed of the terminal illness (96.1% v 76.9%; P <.001). Fifty percent of the family members and 78.3% of the patients thought that the doctor in charge should be the one who informs the patient. Additionally, 71.7% of the patients and 43.6% of the family members thought that patients should be informed immediately after the diagnosis. Stepwise multiple logistic regression indicated that the patient group was more likely than the family group to want the patient to be informed of the terminal illness (odds ratio [OR], 9.76; 95% CI, 4.31 to 22.14), by the doctor (OR, 4.00; 95% CI, 2.61 to 6.11), and immediately after the diagnosis (OR, 3.64; 95% CI, 2.45 to 5.41). CONCLUSION: Our findings indicated that most cancer patients want to be informed if their illness is terminal, and physicians should realize that the patient and the family unit may differ in their attitude toward such a disclosure. Our results also reflect the importance of how information is given to the patient.
