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

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

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

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

PURPOSE: To date, the risk factors for central venous port-related bloodstream infection (CVPBSI) in solid cancer patients have not been fully elucidated. We conducted this study in order to determine the risk factors for CVP-BSI in patients with solid cancer. MATERIALS AND METHODS: A total of 1,642 patients with solid cancer received an implantable central venous port for delivery of chemotherapy between October 2008 and December 2011 in a single center. CVP-BSI was diagnosed in 66 patients (4%). We selected a control group of 130 patients, who were individually matched with respect to age, sex, and catheter insertion time. RESULTS: CVP-BSI occurred most frequently between September and November (37.9%). The most common pathogen was gram-positive cocci (n=35, 53.0%), followed by fungus (n=14, 21.2%). Multivariate analysis identified monthly catheter-stay as a risk factor for CVP-BSI (p=0.000), however, its risk was lower in primary gastrointestinal cancer than in other cancer (p=0.002). Initial metastatic disease and long catheter-stay were statistically significant factors affecting catheter life span (p=0.005 and p=0.000). Results of multivariate analysis showed that recent transfusion was a risk factor for mortality in patients with CVP-BSI (p=0.047). CONCLUSION: In analysis of the results with respect to risk factors, prolonged catheter-stay should be avoided as much as possible. It is necessary to be cautious of CVP-BSI in metastatic solid cancer, especially non-gastrointestinal cancer. In addition, avoidance of unnecessary transfusion is essential in order to reduce the mortality of CVP-BSI. Finally, considering the fact that confounding factors may have affected the results, conduct of a well-designed prospective controlled study is warranted.

RESUMEN

Mucosa-associated lymphoid tissue (MALT) lymphoma is frequently reported in the gastrointestinal tract (GIT), but the incidence is low in the upper aerodigestive tract. In particular, MALT lymphoma of the tongue is very rare. Only four cases have been reported in the English literature to date. We report a case of 29-year-old woman who had a past history of peripheral T cell lymphoma of the head and neck and a new mass at the right base of tongue 3 years later. An incisional biopsy of the base of tongue revealed a new pathology, one that of extranodal marginal zone B cell lymphoma (MALT lymphoma). After staging work-up, she was diagnosed to be at the Ann Arbor stage IE. She was treated with 30.6 Gy of radiation therapy alone and there was no recurrence after 3 years follow-up.

RESUMEN

Castleman's disease (CD) is thought to be related with an initially benign viral disease with cytokine-driven propagation and malignant transformation. This paper reports the first case of a simultaneous discordant lymphoma consisting of lymphocyte-depleted classical Hodgkin's lymphoma (LDCHL) and peripheral T-cell lymphoma (PTCL) arising in a patient with multicentric CD (MCD). PTCL occurred 4 years after the diagnosis of MCD, and LDCHL was developed 6 years after the treatment of PTCL, sequentially. The following year, the patient presented with a relapse of a simultaneous discordant lymphoma. On excisional cervical LN biopsy, immunohistochemical stain pattern was identical with previously diagnosed LDCHL, which expressed CD30, CD15, PAX5, and Epstein-Barr virus (EBV)-encoded RNA. PTCL was positive for CD3, CD4, CD5, CD10, and CD56, and showed identical TCRB and TCRG gene rearrangements to those detected initially. MCD was thought to be the major contributing factor leading to initial PTCL, while EBV-positive LDCHL is thought to have promoted the development of PTCL, as a persistently abnormal immune microenvironment may induce the recurrence of PTCL. MCD runs a more aggressive course and can progress to Hodgkin's lymphoma (HL), non-Hodgkin's lymphoma (NHL), or combined HL/NHL. Due to its malignant potential, prompt recognition and therapy is critical for these situations, which may be life threatening.

RESUMEN

CONTEXT: The Edmonton Symptom Assessment System (ESAS) is a brief, widely adopted, multidimensional questionnaire to evaluate patient-reported symptoms. OBJECTIVES: To develop a Korean version of the ESAS (K-ESAS) and to perform a psychometric analysis in Korean patients with advanced cancer. METHODS: We tested the K-ESAS in two pilot studies with 15 patients each. We assessed internal consistency, test-retest reliability, and concurrent validity in 163 Korean patients, who completed the K-ESAS along with the Korean versions of the M. D. Anderson Symptom Inventory (K-MDASI) and the Hospital Anxiety and Depression Scale (K-HADS) twice. A total of 38 patients completed the questionnaires again seven days later to assess responsiveness. RESULTS: The K-ESAS scores had good internal consistency, with a Cronbach's alpha coefficient of 0.88, indicating that no questions had undue influence on the score. Pearson correlation coefficients for K-ESAS symptom scores between baseline and after two to four hours ranged from 0.72 (95% CI 0.64-0.79) to 0.87 (95% CI 0.82-0.90), indicating strong test-retest reliability. For concurrent validity, Pearson correlation coefficients between K-ESAS symptom scores and corresponding K-MDASI symptom scores ranged from 0.70 (95% CI 0.62-0.77) to 0.83 (95% CI 0.77-0.87), indicating good concurrent validity. For the K-HADS, concurrent validity was good for anxiety (r=0.73, 95% CI 0.65-0.79) but moderate for depression (r=0.4, 95% CI 0.26-0.52). For responsiveness, changes in K-ESAS scores after seven days were moderately correlated with changes in K-MDASI scores but weakly correlated with changes in K-HADS scores. CONCLUSION: The K-ESAS is a valid and reliable tool for measuring multidimensional symptoms in Korean patients with cancer.

RESUMEN

OBJECTIVES: Terminal cancer patients and their caregivers often experience traumatic stress and need many types of assistance. In the present study we interviewed terminally ill cancer patients and caregivers to determine how much burden they experienced and to find out what factors are most important for satisfaction. DESIGN: We constructed a questionnaire including overall care burden and needs experienced, and administered it to 659 terminal cancer patients and 659 important caregivers at 11 university hospitals and 1 national cancer center in Korea. RESULTS: Finally, 481 terminal cancer patients and 381 caregivers completed the questionnaire. Care burden was not insubstantial in both and the caregiver group felt more burden than the patient group (P <0.001). While the patient group needed financial support most (39.0%), the caregiver group placed greatest emphasis on discussion about further treatment plans (44.8%). Stepwise multiple logistic regression analyses showed that in the patient group, patient's health status (OR, 2.03; 95% CI, 1.16-3.56) and burden (OR, 2.82; 95% CI, 1.76-4.50) influenced satisfaction about overall care, while in the caregiver group, high education level`(OR, 1.84; 95% CI, 1.76-4.50), burden (OR, 2.94; 95% CI, 1.75-4.93) and good family function (OR, 1.94; 95% CI, 1.24-3.04) were important. CONCLUSIONS: Our study showed that burden was great in both terminal cancer patients and their caregivers and was perceived to be more severe by caregivers. Our study also showed that burden was the factor most predicting satisfaction about overall care in both groups.

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.

RESUMEN

Recent development of personal sequencers for extensive mutation analysis and bead array technology for comprehensive DNA methylation analysis have made it possible to obtain integrated pictures of genetic and epigenetic alterations on the same set of cancer samples. Here, we aimed to establish such pictures of gastric cancers (GCs). Comprehensive methylation analysis of 30 GCs revealed that the number of aberrantly methylated genes was highly variable among individual GCs. Extensive mutation analysis of 55 known cancer-related genes revealed that 19 of the 30 GCs had 24 somatic mutations of eight different genes (CDH1, CTNNB1, ERBB2, KRAS, MLH1, PIK3CA, SMARCB1, and TP53). Integration of information on the genetic and epigenetic alterations revealed that the GCs with the CpG island methylator phenotype (CIMP) tended to have mutations of oncogenes, CTNNB1, ERBB2, KRAS, and PIK3CA. This is one of the first studies in which both genetic and epigenetic alterations were extensively analyzed in the same set of samples. It was also demonstrated for the first time in GCs that the CIMP was associated with oncogene mutations.

RESUMEN

PURPOSE: It is important to balance the appropriateness of active cancer treatments and end-of-life care to improve the quality of life for terminally ill cancer patients. This study describes the treatment patterns and end-of-life care in terminal gastric cancer patients. MATERIALS AND METHODS: We retrospectively analyzed the records of 137 patients with advanced gastric cancer receiving chemotherapy and dying between June 1, 2006 and May 31, 2011. We recorded interval between last chemotherapy dose and death; frequency of emergency room visits or admission to the intensive care unit in the last month before death; rate of hospice referral and agreement with written do-not-resuscitate orders; and change in laboratory values in the last three months before death. RESULTS: During the last six months of life, 130 patients (94.9%) received palliative chemotherapy; 86 (62.7%) during the final two months; 41 (29.9%) during the final month. During the final month, 53 patients (38.7%) visited an emergency room more than once; 21 (15.3%) were admitted to the intensive care unit. Hospice referral occurred in 54% (74 patients) of the patients; 93.4% (128 patients) gave written do-not-resuscitate orders. Platelets, aspartate aminotransferase and creatinine changed significantly two weeks before death; total bilirubin, one month before; and C-reactive protein, between four and two weeks before death. CONCLUSION: Our results demonstrated that a significant proportion of gastric cancer patients received palliative chemotherapy to the end of life and the patients who stopped the chemotherapy at least one month before death had a lower rate of intensive care unit admission and longer overall survival than those who sustained aggressive chemotherapy until the last months of their lives.

RESUMEN

BACKGROUND: Surgery alone is no longer an adequate standard of care for patients with resectable gastric cancer. Thus, research efforts should focus on which regimens are the most effective for patients with recurrent gastric cancer after combined treatment with surgery and perioperative or adjuvant chemotherapy. METHODS: Patients with histologically confirmed and measurable advanced gastric cancer who showed a relapse even after fluoropyrimidine and/or cisplatin-based adjuvant chemotherapy received docetaxel (35 mg/m(2)) intravenously on day 1 and 8 plus oxaliplatin (100 mg/m(2)) intravenously on day 1 every 3 weeks until disease progression or unacceptable toxicity. RESULTS: A total of 34 patients with relapsed advanced gastric cancer who had received adjuvant chemotherapy with fluoropyrimidine and/or cisplatin for a median of 6 months (range, 1-48 months) were enrolled in this trial; 22 (64.7 %) patients had been exposed to both agents. Their median age was 58 years (range, 50-68 years). The overall response rate was 55.9 % (95 % confidence interval (CI), 38.3-73.5 %), including 1 complete response and 18 partial responses. At a median follow-up duration of 28.5 months (range, 9.2-50.7 months), the median progression-free survival for all patients was 5.3 months (95 % CI, 4.4-6.1 months) and the median overall survival was 13.8 months (95 % CI, 11.1-16.4 months). The most common grade 3 or 4 hematologic and nonhematologic toxicities were neutropenia (47.1 %) and diarrhea (17.6 %), respectively. Five patients (14.7 %) experienced febrile neutropenia. CONCLUSIONS: Docetaxel and oxaliplatin combination chemotherapy was active and tolerable in patients with recurrent gastric cancer after fluoropyrimidine and/or cisplatin-based adjuvant chemotherapy.

RESUMEN

OBJECTIVES: To investigate in depth the use of complementary and alternative medicines (CAMs) by cancer patients at the end-of-life (EOL) and how they communicate with physicians about them. DESIGN AND LOCATION: In 17 hospitals in Korea between January and December 2004 we identified 4,042 families of cancer patients. RESULTS: The prevalence of CAM use among cancer patients at the EOL was 37.0%, and 93.1% had used pharmacologic types of agents. The most frequent motive for CAM use was the recommendation of friends or a close relative (53.4%) or a physician (1.6%). Only 42.5% discussed CAM use with their physicians. Satisfaction with CAMS was recalled for 37.1% . The most common reason given for that satisfaction was improvement of emotional or physical well-being, while ineffectiveness was the most common reason given for dissatisfaction. The average cost of CAM during the last month of life was $US 900. CAM use was associated with longer disease periods, primary cancers other than liver, biliary, and pancreatic, and need of support from physicians or religion. CONCLUSIONS: CAM use among cancer patients at the EOL was common, not discussed with physicians, and associated with expectation of cure. Expectations were generally unmet while the treatments were a financial burden. Further studies evaluating the effects of CAM at the EOL and factors that enhance communication with the physician are needed.

RESUMEN

PURPOSE: We tested whether a decision aid explaining how to discuss the approach of death with a family member with cancer would help family caregivers decide to discuss a terminal prognosis. PATIENTS AND METHODS: We randomly assigned caregivers of terminally ill patients with cancer to a group that received a video and a companion workbook that showed either how they can discuss the prognosis with their patient (experimental arm) or how cancer pain can be controlled (control arm). At baseline and 1 month, we evaluated the decision to discuss terminal prognosis as the primary outcome. At 0, 1, 3, and 6 months, we assessed the caregivers' decisional conflict and satisfaction as secondary outcomes using a Decision Conflict Scale (DCS). RESULTS: We found no difference in changes in the decision to discuss terminal prognosis between the two groups. Conflict (P = .003), uncertainty (P = .019), and value clarity (P = .007) subscale scores and total DCS score (P = .008) improved from baseline to 1 month significantly more in the experimental arm than in the control arm. Over 6 months, the significant between-group differences continued for the conflict (P = .031), uncertainty (P = .014), and value clarity (P = .039) subscale scores and total DCS score (P = .040). CONCLUSION: Decision aids can help caregivers, with the aid of trained professionals, to communicate with patients about their terminal illness.
