Temporal trajectory of quality of life and its predictors in recipients of hematopoietic stem cell transplantation.

This prospective longitudinal study evaluated the temporal trajectory of health-related quality of life (HRQOL) and its associated factors in patients who received hematopoietic stem cell transplantation (SCT) 6 months after transplantation. Eighty-nine adult patients who were admitted to Seoul National University Hospital for SCT were consecutively included in the study. The participants completed three standardized questionnaires: Insomnia Severity Index, Hospital Anxiety and Depression Scale, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. The participants completed the study questionnaires at three time points: before SCT (T1), immediately after SCT (T1), and 6 months after SCT (T3). Immediately after SCT, HRQOL decreased significantly (p < 0.001), followed by recovery over 6 months. The conditioning regimen for SCT showed no correlation with HRQOL at T2 (p = 0.283) or T3 (p = 0.799), with no significant difference in HRQOL between allogeneic and autologous SCT recipients at T2 (p = 0.829) or T3 (p = 0.824). Depression (p = 0.042), pain (p = 0.023), and appetite loss (p = 0.004) negatively influenced HRQOL at T1, whereas only pain (p = 0.048) remained an important factor at T2. Six months after SCT, the two most frequent symptoms, fatigue and financial problems, became major factors (p = 0.004 and p = 0.005, respectively). Depression began to play an important role in HRQOL again at T3 (p = 0.040). These findings demonstrate that SCT recipients need both psychological and medical support to achieve a better HRQOL after SCT.

Preoperative chemoradiotherapy for elderly patients with locally advanced rectal cancer-a real-world outcome study.

OBJECTIVE: Preoperative chemoradiotherapy has been established as a standard treatment for locally advanced rectal cancer. It is unclear whether preoperative chemoradiotherapy is truly beneficial in the elderly patients. Our aim was to assess the impact of age on the treatment tolerance and clinical outcomes. METHODS: We retrospectively analyzed 160 consecutive patients with clinical stage T3-4, and/or lymph node positive tumors who received preoperative chemoradiotherapy from May 2003 to December 2010 at a single hospital. Treatment tolerance and outcomes were compared between patients ≥70 years (N = 56) and <70 years (N = 104). RESULTS: There was no disparity in the achievement of prescribed radiation dose and dose reduction of chemotherapy between two groups. Pathologic complete response rate (15.6% vs. 16.0%) and sphincter preservation rate (91.1% vs. 95.0%; P = 0.459) were not significantly different. The 3-year disease-free survival of older vs. younger patients was 77.8% vs. 92.3% and 5-year disease-free survival was 60.0% vs. 78.6%, respectively (P = 0.023). In multivariable analysis, age was significantly associated with disease-free survival (P = 0.033) but comorbidities were not (P = 0.092). However, both age (hazard ratio, 2.331; P = 0.028) and comorbidities (hazard ratio, 2.772; P = 0.031) were significantly associated with overall survival as well as clinical stage. Anemia was the only adverse effect more prominent in older patients. CONCLUSIONS: Older patients showed non-inferior compliance and equivalent pathologic complete response rates without an increased incidence of treatment complications with preoperative chemoradiotherapy. More comprehensive consideration than age alone is warranted in the decision of applying preoperative chemoradiotherapy to elderly patients with rectal cancer.

Comparison of prophylactic effects for chemotherapy induced neutropenia between same-day versus next-day administration of pegteograstim (Neurapeg®) in patients treated with chemotherapy regimen composed of day 1 intensive myleosuppressive agent: A randomized phase III clinical trial.

BACKGROUND AND PURPOSE: Administration of pegylated granulocyte-colony-stimulating factor (peg-GCSF) 24 to 72 hours after chemotherapy is usually recommended. Next-day administration (after 24 hours) resulted in fewer duration of grade (Gr) 4 chemotherapy-induced neutropenia (CIN) and decreased severity of CIN than same-day (within 4 hours). However, patients sometimes receive same-day Peg-GCSF for the sake of convenience. In addition, a few prior studies showed that the same-day method is comparable or superior to the next-day method in preventing CIN, especially in chemotherapy regimens that include day 1 myelosuppressive agents. Thus, we aim to verify the hypothesis that same-day administration of pegteograstim, a new formulation of peg-GCSF, is non-inferior to next-day administration in terms of Gr4 CIN duration. METHODS: This study is a randomized, multicenter, open-label, investigator-initiated phase 3 study. Patients with adjuvant/neoadjuvant or first-line palliative chemotherapy comprising intensively myelosuppressive agents on day 1 (mFOLFIRINOX, ECb, EP, FOLFIRI, and FOLFOX) are enrolled. The patients are assigned to the same-day arm or the next-day arm in a 1:1 ratio. The randomizations are stratified according to number of patient CIN risk factors (1 vs ≥2), chemotherapy setting (perioperative vs palliative), and interval (2-week vs 3-week). In the same-day arm, pegteograstim 6 mg is subcutaneously injected within 4 hours after completion of chemotherapy. In the next-day arm, pegetograstim is injected at 24 to 36 hours post-chemotherapy. A complete blood count test is performed daily from day 5 to 9 during the cycle 1. The primary endpoint is duration of Gr4 CIN (cycle 1), and secondary endpoints include incidence of Gr 3 to 4 CIN (cycle 1), severity of CIN (cycle 1), time to recovery absolute neutrophil count 1000/µL (cycle 1), incidence of febrile neutropenia, incidence of CIN-related dose delay, and dose intensity. In order to verify non-inferiority of 0.6 days, we estimated a significance level of 5%, power of 80%, and drop-out rate of 15%. This results in the need for a total of 160 patients, 80 in each group.

Metastatic adrenocortical carcinoma presenting simultaneously with Cushing's and Conn's syndromes: a case report.

We report the first case of adrenocortical carcinoma secreting cortisol (Cushing's syndrome) and aldosterone (Conn's syndrome) with extensive distant metastasis at the time of diagnosis. A 72-year-old male with exertional dyspnea sought evaluation at our institution. The pattern of tumor spread (lung, pleura, bone and adrenal gland) and respiratory symptoms secondary to the tumor led clinicians to diagnose the primary tumor site as lung cancer and the adrenal mass as a metastatic site. However, endocrinologic studies and a biopsy revealed the primary site to be adrenocortical carcinoma. After histopathologic confirmation, the patient was treated with palliative chemotherapy, including mitotane, cisplatin, etoposide and doxorubicin. The patient died on the 14th day after chemotherapy of rapidly progressive and unexpected pneumonia, which was thought to be an opportunistic infection secondary to Cushing's syndrome. Our case suggests that a thorough endocrinologic investigation is important in patients with an adrenal mass and clinicians should be aware that patients with adrenocortical carcinoma and Cushing's syndrome are susceptible to infections and need to be observed carefully for the possible development of unrecognized opportunistic infections.

Real-world efficacy and safety of liposomal irinotecan plus fluorouracil/leucovorin in patients with metastatic pancreatic adenocarcinoma: a study by the Korean Cancer Study Group.

BACKGROUND: Liposomal irinotecan (nal-IRI) plus 5-fluorouracil and leucovorin (5-FU/LV) was effective and well-tolerated in patients with metastatic pancreatic adenocarcinoma (mPAC) that progressed on gemcitabine-based therapy in the global NAPOLI-1 trial. Real-world data may further clarify the outcomes and safety profile of nal-IRI + 5-FU/LV in clinical practice. METHODS: This retrospective analysis included patients with mPAC who received nal-IRI + 5-FU/LV following gemcitabine-based therapy under a Managed Access Program in Korea. RESULTS: From January 2017 to April 2018, 86 patients across 10 institutions received nal-IRI + 5-FU/LV (median age, 61 years; 60% male; ECOG performance status, 0-1). A total of 35 (41%) and 51 (59%) patients had received less than two and two or more lines of chemotherapy before inclusion, respectively. At a median follow up of 6.4 months, median overall survival (OS) was 9.4 months (95% confidence interval [CI] 7.4-11.4) and median progression-free survival (PFS) was 3.5 months (95% CI 1.3-5.7). Six-month OS and PFS rates were 65.1% and 37.5%, respectively. Objective response and disease control rates were 10% and 55%, respectively. Most common grade 3-4 toxicities were neutropenia (37.2%), nausea (10.5%), vomiting (9.3%), anorexia (8.1%) and diarrhoea (4.7%). CONCLUSION: Real-life data for Korean patients indicate that, consistent with NAPOLI-1, nal-IRI + 5-FU/LV is effective and well-tolerated in patients with mPAC that progressed on gemcitabine-based therapy.

More Accurate Prediction of Metastatic Pancreatic Cancer Patients' Survival with Prognostic Model Using Both Host Immunity and Tumor Metabolic Activity.

INTRODUCTION: Neutrophil to lymphocyte ratio (NLR) and standard uptake value (SUV) by 18F-FDG PET represent host immunity and tumor metabolic activity, respectively. We investigated NLR and maximum SUV (SUVmax) as prognostic markers in metastatic pancreatic cancer (MPC) patients who receive palliative chemotherapy. METHODS: We reviewed 396 MPC patients receiving palliative chemotherapy. NLR was obtained before and after the first cycle of chemotherapy. In 118 patients with PET prior to chemotherapy, SUVmax was collected. Cut-off values were determined by ROC curve. RESULTS: In multivariate analysis of all patients, NLR and change in NLR after the first cycle of chemotherapy (ΔNLR) were independent prognostic factors for overall survival (OS). We scored the risk considering NLR and ΔNLR and identified 4 risk groups with different prognosis (risk score 0 vs 1 vs 2 vs 3: OS 9.7 vs 7.9 vs 5.7 vs 2.6 months, HR 1 vs 1.329 vs 2.137 vs 7.915, respectively; P<0.001). In PET cohort, NLR and SUVmax were independently prognostic for OS. Prognostication model using both NLR and SUVmax could define 4 risk groups with different OS (risk score 0 vs 1 vs 2 vs 3: OS 11.8 vs 9.8 vs 7.2 vs 4.6 months, HR 1 vs 1.536 vs 2.958 vs 5.336, respectively; P<0.001). CONCLUSIONS: NLR and SUVmax as simple parameters of host immunity and metabolic activity of tumor cell, respectively, are independent prognostic factors for OS in MPC patients undergoing palliative chemotherapy.

The Impact of Diabetes Mellitus and Metformin Treatment on Survival of Patients with Advanced Pancreatic Cancer Undergoing Chemotherapy.

PURPOSE: A causal relationship between diabetes mellitus (DM) and pancreatic cancer is well established. However, in patients with advanced pancreatic cancer (APC) who receive palliative chemotherapy, the impact of DM on the prognosis of APC is unclear. MATERIALS AND METHODS: We retrospectively enrolled APC patients who received palliative chemotherapy between 2003 and 2010. The patients were stratified according to the status of DM, in accordance with 2010 DM criteria (American Heart Association/American Diabetes Association). DM at least 2 years' duration prior to diagnosis of APC was defined as remote-onset DM (vs. recent-onset). RESULTS: Of the 349 APC patients, 183 (52.4%) had DM. Among the patients with DM, 160 patients had DM at the time of diagnosis of APC (remote-onset, 87; recent-onset, 73) and the remaining 23 patients developed DM during treatment of APC. Ultimately, 73.2% of patients (134/183) with DM received antidiabetic medication, including metformin (56 patients, 41.8%), sulfonylurea (62, 45.5%), and insulin (43, 32.1%). In multivariate analysis, cancer extent (hazard ratio [HR], 1.792; 95% confidence interval [CI], 1.313 to 2.445; p < 0.001) showed association with decreased overall survival (OS), whereas a diagnosis of DM (HR, 0.788; 95% CI, 0.615 to 1.009; p=0.059) conferred positive tendency on the OS. Metformin treatment itself conferred better OS in comparison within DM patients (HR 0.693; 95% CI, 0.492 to 0.977; p=0.036) and even in all APC patients (adjusted HR, 0.697; 95% CI, 0.491 to 1.990; p=0.044). CONCLUSION: For APC patients receiving palliative chemotherapy, metformin treatment is associated with longer OS. Patients with DM tend to survive longer than those without DM.

Concurrent Chemoradiotherapy Versus Chemotherapy Alone for Unresectable Locally Advanced Pancreatic Cancer: A Retrospective Cohort Study.

PURPOSE: The optimal treatment strategy for locally advanced pancreatic cancer (LAPC), particularly the role of concurrent chemoradiotherapy (CCRT), remains debatable. We compared the clinical outcomes of CCRT and palliative chemotherapy alone (CA) in patients with unresectable LAPC. MATERIALS AND METHODS: Patients with LAPC who were consecutively treated between 2003 and 2010 were included. Resectability was evaluated according to National Comprehensive Cancer Network ver. 1.2012. The clinical outcomes for each treatment group (CCRT vs. CA) were evaluated retrospectively. RESULTS: Sixty-three patients (58.9%) and 44 patients (41.1%) were treated with CCRT and CA, respectively. The CCRT cohort included patients who were treated with CCRT with or without chemotherapy backbone (CCRT alone, induction chemotherapy-CCRT, CCRT-maintenance chemotherapy, and induction-CCRT-maintenance chemotherapy). Median progression-free survival (PFS) and overall survival (OS) of all patients were 7.2 months and 13.1 months. PFS of the CCRT and CA groups was 9.0 months and 4.4 months, respectively (p=0.020). OS of the CCRT and CA groups was 15.4 months and 9.3 months, respectively (p=0.011). In multivariate analysis, the adjusted hazard ratio of CCRT was 0.536 (p=0.003) for OS and 0.667 (p=0.078) for PFS. Although the pattern of failure was similar in the CCRT and CA groups, the times to both local and distant failure were significantly longer in the CCRT group. CONCLUSION: In patients with unresectable LAPC, those who underwent CCRT during their entire treatment courses had longer OS than patients treated with chemotherapy alone.

Cancer Treatment near the End-of-Life Becomes More Aggressive: Changes in Trend during 10 Years at a Single Institute.

PURPOSE: The purpose of this study was to investigate and compare cancer treatment near the end-of-life (EOL) over a 10-year period. MATERIALS AND METHODS: Patients with advanced solid cancer at Seoul National University Hospital who received palliative chemotherapy and had died were enrolled. We categorized the consecutive patients according to two time periods: 2002 (n=57) and 2012 (n=206). Aggressiveness of cancer treatment near the EOL was evaluated. RESULTS: The median patient age was 62, and 65.4% of patients (n=172) were male. Time from the last chemotherapy to death (TCD) was found to have been significantly shortened, from 66.0 days to 34.0 days during 10 years (p < 0.001); 17% of patients received molecular targeted agents as the last chemotherapy regimen in 2012. The proportion of patients who received intensive care unit care within the last month increased from 1.8% in 2002 to 19.9% in 2012 (p < 0.001), and emergency room visits within the last month also increased from 22.8% to 74.8% (p < 0.001). Although hospice referral increased from 9.1% to 37.4% (p < 0.001), timing of referral was delayed from median 53 days to 8 days before death (p=0.004). Use of targeted agents as the last chemotherapy for over-two-regimen users was associated with shortened TCD (hazard ratio, 2.564; p=0.002). CONCLUSION: Cancer treatment near the EOL became more aggressive over 10 years.

Skeletal Muscle Depletion Predicts the Prognosis of Patients with Advanced Pancreatic Cancer Undergoing Palliative Chemotherapy, Independent of Body Mass Index.

INTRODUCTION: Body composition has emerged as a prognostic factor in cancer patients. We investigated whether sarcopenia at diagnosis and loss of skeletal muscle during palliative chemotherapy were associated with survival in patients with pancreatic cancer. METHODS: We retrospectively reviewed the clinical outcomes of pancreatic cancer patients receiving palliative chemotherapy between 2003 and 2010. The cross-sectional area of skeletal muscle at L3 by computed tomography was analyzed with Rapidia 3D software. We defined sarcopenia as a skeletal muscle index (SMI)< 42.2 cm2/m2 (male) and < 33.9 cm2/m2 (female) using ROC curve. RESULTS: Among 484 patients, 103 (21.3%) patients were sarcopenic at diagnosis. Decrease in SMI during chemotherapy was observed in 156 (60.9%) male and 65 (40.6%) female patients. Decrease in body mass index (BMI) was observed in 149 patients (37.3%), with no gender difference. By multivariate analysis, sarcopenia (P< 0.001), decreasedBMI and SMI during chemotherapy (P = 0.002, P = 0.004, respectively) were poor prognostic factors for overall survival (OS). While the OS of male patients was affected with sarcopenia (P< 0.001) and decreased SMI (P = 0.001), the OS of female patients was influenced with overweight at diagnosis (P = 0.006), decreased BMI (P = 0.032) and decreased SMI (P = 0.014). Particularly, while the change of BMI during chemotherapy did not have impact on OS within the patients with maintained SMI (P = 0.750), decrease in SMI was associated with poor OS within the patients with maintained BMI (HR 1.502; P = 0.002). CONCLUSIONS: Sarcopenia at diagnosis and depletion of skeletal muscle, independent of BMI change, during chemotherapy were poor prognostic factors in advanced pancreatic cancer.

The impact of body mass index dynamics on survival of patients with advanced pancreatic cancer receiving chemotherapy.

CONTEXT: High body mass index (BMI) is linked to an increased risk of developing pancreatic cancer (PC). However, in patients with advanced PC (APC), especially those receiving palliative chemotherapy, the impact of BMI on survival has not been investigated fully. OBJECTIVES: To assess changes in BMI during the course of APC and their impact on patient survival, specifically for those receiving palliative chemotherapy. METHODS: Consecutive patients with APC, all of whom were treated with palliative chemotherapy, were enrolled during 2003-2010. Clinical characteristics and prognoses were analyzed. RESULTS: A total of 425 patients participated (median age, 60.1 years). At diagnosis of APC, patients' BMI distribution of patients was as follow: <18.5 (45, 10.6%); 18.5-19.9 (67, 15.8%); 20.0-22.4 (156, 36.7%); 22.5-24.9 (107, 25.2%); 25.0-29.9 (49, 11.5%); and ≥ 30.0 (1, 0.2%). Median overall survival (OS) was 8.1 months (95% confidence interval 7.2, 9.1). Precancer BMI and baseline BMI (at diagnosis) had no impact on OS. Weight loss at diagnosis (precancer weight minus weight at diagnosis) and weight loss during first-line chemotherapy (both stipulated as BMI change ≥ 1) were associated with shortened OS (hazard ratio, 1.300; P = 0.012 and hazard ratio, 1.367; P = 0.010, respectively). CONCLUSION: In patients with APC undergoing palliative chemotherapy, decreases in BMI at APC diagnosis and during chemotherapy are more hazardous for OS than precancer BMI or baseline BMI (at diagnosis) as absolute values. Further studies are needed to validate this finding and investigate strategies to maintain BMI during chemotherapy in this setting.

A case report of breast cancer with extensive pulmonary lymphovascular tumor emboli.

We describe a patient with breast cancer who relapsed with an extensive pulmonary lymphovascular tumor embolism. A 38-year-old female, who previously received neoadjuvant chemotherapy and curative resection of breast cancer, underwent adjuvant chemotherapy and was referred to the emergency room because of sudden-onset pleuritic chest pain lasting for 10 days. Despite a trial of empirical antibiotics, the chest pain and the extent of consolidative lung lesion on chest radiographs rapidly aggravated. We performed an open lung biopsy to confirm the etiology. The histopathological review revealed a hemorrhagic infarction caused by lymphovascular tumor emboli from a metastatic breast carcinoma. Palliative first-line chemotherapy was administered, consisting of ixabepilone and capecitabine, and the lung lesion improved markedly.

Hematological manifestations of human immunodeficiency virus infection and the effect of highly active anti-retroviral therapy on cytopenia.

BACKGROUND: The aim of this study is to investigate the hematological manifestations of human immunodeficiency virus (HIV) infection, the risk factors for cytopenia, and the effect of highly active anti-retroviral therapy (HAART) on cytopenia. METHODS: Medical records of patients treated for HIV at the Seoul National University Hospital from January 2005 to March 2010 were retrospectively reviewed. To determine the impact of HIV itself, we excluded HIV patients who had other conditions that could have resulted in hematological manifestations. Multiple logistic regression analyses were performed to identify risk factors for cytopenia. RESULTS: A total of 621 cases were investigated, and after exclusion, data of 472 patients were analyzed. The frequency of cytopenia was anemia, 3.0% (14/472); neutropenia, 10.0% (47/472); thrombocytopenia, 2.4% (12/472); lymphopenia, 25.7% (121/470); isolated cytopenia, 11.2% (53/472); and bicytopenia, 2.1% (10/472). The leading risk factor for cytopenia identified by multivariate logistic regression methods was AIDS status at initial presentation. After HAART, cytopenia was reversed in the majority of patients (thrombocytopenia, 100%; neutropenia, 91.1%; and anemia, 84.6%). CONCLUSION: This study isolated the impact of HIV infection alone on hematologic manifestations and confirmed that these changes were reversible by HAART. Control of the HIV infection will have the main role in the management of hematological manifestations of the virus.

Acute lymphoblastic leukemia in elderly patients: a single institution's experience.

BACKGROUND/AIMS: We investigated the clinical characteristics and prognosis of elderly patients with acute lymphoblastic leukemia (ALL). METHODS: We reviewed the clinical data, laboratory findings, bone marrow findings, and cytogenetic analysis of elderly patients (≥ 60 years) with ALL, and data of an additional 101 younger adult patients (< 60 years) with ALL were reviewed for comparison. RESULTS: Twenty-six elderly patients (≥ 60 years) and 101 younger adult patients (< 60 years) with ALL were retrospectively enrolled. The median follow-up duration was 6.0 months (range, 0.4 to 113.2) in the elderly patients and 21.7 months (range, 1.0 to 122.7) in the adult patients. In total, 34.6% (9 patients) of the elderly patients and 24.8% (25 patients) of the adult patients had Philadelphia chromosome positive ALL. The overall complete remission (CR) rate was much higher in the younger than in the elderly patients (94.1% vs. 57.7%, p < 0.001). The median overall survival (OS) of the younger patients (< 60 years) was 26.3 months, whereas that of the elderly patients (≥ 60 years) was 10.3 months (p = 0.003). In the elderly patients with ALL, T cell lineage and the presence of lymphadenopathy were significant prognostic factors for OS in a univariate analysis (p = 0.033 and 0.041, respectively). CONCLUSIONS: The outcomes of Korean elderly patients with ALL were poor, and the shorter OS was mainly due to the low CR rate. T-cell lineage and the presence of lymphadenopathy were significant prognostic factors in Korean elderly patients with ALL.
