Clinical outcomes of liposomal irinotecan plus fluorouracil/leucovorin for metastatic pancreatic adenocarcinoma in patients previously treated with conventional irinotecan-containing chemotherapy

Introduction: Liposomal irinotecan (nal-IRI) plus fluorouracil/leucovorin (5-FU/LV) has shown clinical benefit in patients with metastatic pancreatic adenocarcinoma (mPAC) who progressed on gemcitabine-based chemotherapy. However, its role in patients with mPAC previously treated with conventional irinotecan-containing chemotherapy has not been appropriately investigated. Methods: In this retrospective analysis, patients with mPAC who received nal-IRI plus 5-FU/LV after conventional irinotecan-containing regimen between January 2017 and March 2020, were identified from two referral cancer centers in South Korea. The ratio of time to progression (TTP) with nal-IRI plus 5-FU/LV to TTP with conventional irinotecan (TTPr) was analyzed with respect to the duration and cumulative dose of conventional irinotecan treatment. Results: In total, 35 patients treated with nal-IRI plus 5-FU/LV after the irinotecan-containing regimen were analyzed. The median age was 58 years and 16 (46%) patients were male. The median duration of conventional irinotecan therapy was 4.6 months at a median cumulative dose of 1230 mg. The objective response rate of nal-IRI plus 5-FU/LV was 2.9%, and stable disease was achieved in 11 (31.4%) patients. During the median follow-up of 9.2 [95% confidence interval (CI): 7.8-10.5] months, the median progression-free survival (PFS) and overall survival (OS) were 2.0 (95% CI: 1.4-2.6) months and 4.4 (95% CI: 3.6-5.7) months, respectively. The 6-month PFS and OS rates were 16.3% and 37.5%, respectively. The median TTPr was 0.41 (range, 0.07-2.07), showing a negative correlation with the cumulative dose of prior irinotecan therapy (R = -0.37, p = 0.041). A tentative negative correlation between TTPr and duration of prior irinotecan therapy was observed (R = -0.35, p = 0.062). The most common grade 3-4 toxicities were neutropenia (20%) and fatigue (8.6%). Conclusion: Nal-IRI plus 5-FU/LV showed modest effectiveness and manageable toxicities for patients with mPAC previously treated with conventional irinotecan-containing chemotherapy. The cumulative dose of prior conventional irinotecan therapy may be inversely correlated with the effectiveness of nal-IRI plus 5-FU/LV

Changes in decision-making process for life-sustaining treatment in patients with advanced cancer after the life-sustaining treatment decisions-making act

Background Cancer is a leading cause of death in Korea. To protect the autonomy and dignity of terminally ill patients, the Life-Sustaining Treatment Decision-Making Act (LST-Act) came into full effect in Korea in February 2018. However, it is unclear whether the LST-Act influences decision- making process for life-sustaining treatment (LST) for terminally ill cancer patients. Methods This was a retrospective study conducted with a medical record review of cancer patients who died at Ulsan University Hospital between July 2015 and May 2020. Patients were divided into two groups: those who died in the period before the implementation of the LST-Act (from July 2015 to October 2017, Group 1) and after the implementation of the LST-Act (from February 2018 to May 2020, Group 2). We measured the self-determination rate and the timing of documentation of do-not-resuscitate (DNR) or Physician Orders for Life-Sustaining Treatment (POLST) in both groups. Results A total of 1,834 patients were included in the analysis (Group 1, n = 943; Group 2, n = 891). Documentation of DNR or POLST was completed by patients themselves in 1.5 and 63.5 % of patients in Groups 1 and 2, respectively (p < 0.001). The mean number of days between documentation of POLST or DNR and death was higher in Group 2 than in Group 1 (21.2 days vs. 14.4 days, p = 0.001). The rate of late decision, defined as documentation of DNR or POLST within 7 days prior to death, decreased significantly in Group 2 (56.1 % vs. 47.6 %, p < 0.001). In the multivariable analysis, female patients (odds ratio [OR] 0.71, p = 0.002) and patients with more than 12 years of education (OR 0.70, p = 0.019) were significantly related to a reduced rate of late decision. More than 12 years of education (OR 0.53, p = 0.018) and referral to hospice palliative care (OR 0.40, p < 0.001) were significantly related to self-determination. Enforcement of LST-Act was related to a reduced rate of surrogate decision-making (OR 0.01, p < 0.001) and late decision (OR 0.51, p < 0.001). However, physicians with clinical experience of less than 3 years had a higher rate of surrogate decision-making (OR 5.08, p = 0.030) and late decision (OR 2.47, p = 0.021). Conclusions After the implementation of the LST-Act, the rate of self-determination increased and decisions for LST occurred earlier than in the era before the implementation of the LST-Act

Leuprorelin combined with letrozole with/without everolimus in ovarian-suppressed premenopausal women with hormone receptor-positive, HER2-negative metastatic breast cancer: The LEO study

Purpose: In the randomised phase II LEO trial, we investigated the effect of adding everolimus (EVE) to letrozole (LET) in ovarian-suppressed premenopausal women with hormone receptor-positive (HR+), HER2-negative (HER2-) recurrent/metastatic breast cancer. Methods: Patients with progression or prior exposure to tamoxifen with or without gonadotropin-releasing hormone agonists, either sequentially or concurrently, in adjuvant or metastatic setting were randomly assigned (2 : 1) to the EVE arm (leuprorelin + LET + EVE) or the LET arm (leuprorelin + LET) until disease progression or unacceptable toxicity. The primary end-point was progression-free survival (PFS). Secondary end-points included overall survival (OS), objective response rate (ORR), clinical benefit rate (CBR) and safety. Results: Between January 2014 and October 2018, 137 patients were enrolled (median age, 44 years [range, 24-56]). Of them, 75% had endocrine-sensitive disease, and 61% had visceral metastasis. With the median follow-up of 32.4 months, the median PFS was 18.1 months in the EVE arm and 13.8 months in the LET arm (HR 0.73, P = 0.137). Among patients with visceral metastases, the median PFS was significantly longer in the EVE arm (16.4 versus 9.5 months, P = 0.048). The median OS was not reached in both arms. The CBR was significantly higher in the EVE arm (83% versus 62%, P = 0.010). The ORR was similar between the two arms. The most common grade 3/4 adverse events in the EVE arm were neutropenia, alanine aminotransferase elevation and anaemia. Conclusions: EVE plus LET with ovarian-suppression resulted in longer PFS in tamoxifen-exposed HR+, HER2- metastatic breast cancer patients with visceral metastasis. (C) 2020 Elsevier Ltd.

Late complications and quality of life assessment for survivors receiving allogeneic hematopoietic stem cell transplantation

Purpose: The survival rates of patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) have improved. However, HSCT can induce significant long-term complications. Therefore, we investigated the late complications and risk factors for quality of life (QOL) post-HSCT. Methods: We retrospectively analyzed 67 adult survivors over 2?years after HSCT between 2015 and 2018 at Ulsan University Hospital, Ulsan, Korea. The survey data including FACT-BMT, Hospital Anxiety and Depression Scale, and NCCN Distress Thermometer were collected as patient-reported outcomes using a tablet PC during a routine practice of survivorship clinic. Results: The median age was 46?years. The most common symptom was fatigue (80.6%). Younger age (< 60?years), acute lymphoblastic leukemia (ALL), chronic graft-versus-host disease (GVHD), and immunosuppressant use were significantly associated with worse QOL and depression. Additionally, younger survivors (< 60?years) showed significantly more fatigue and anxiety compared with elderly survivors (≥ 60?years). Female sex was significantly associated with lower physical well-being and higher distress than male sex. Conclusion: Younger patients (< 60?years), female, ALL, chronic GVHD, and continuous immunosuppressant use were significant risk factors for worse QOL and depression. Hence, creating a more active survivorship care plan after HSCT, specifically for these patients, is required

Unmet needs related to the quality of life of advanced cancer patients in Korea: a qualitative study

BackgroundIt has recently been emphasized that the unmet needs of cancer patients should be evaluated more holistically, for example, by exploring caregivers' perspectives and cross cultural differences. This study explored additional domains or items of unmet needs among Korean cancer patients in reference to the Sheffield Profile for Assessment and Referral to Care (SPARC).MethodsWe conducted four focus group discussions (FGDs) with 15 cancer patients, following a semi-structured format to elicit participants' health perceptions, comments on SPARC, and opinions on the roles of medical professionals to improve the health-related quality of life of cancer patients. We analyzed the verbatim transcripts using a content analysis method.ResultsThe following themes were derived: living as a cancer patient, striving to overcome cancer, changing attitudes toward life after the cancer diagnosis, and ways to live a better life as a cancer patient. The participants asserted the significance of providing adequate treatment information that is easily understood by cancer patients during the conversation between patients and medical professionals. Besides the physical symptoms identified by SPARC, the participants struggled with numbness in their hands and feet and hair loss. Korean cancer patients prominently wished to avoid burdening their family or others in their daily life. They considered the improvement of health behaviors, such as diet and exercise, as part of the treatment, which was not limited to drugs. Furthermore, it was essential to evaluate the value of cancer patients' lives, as they desired to be helpful members of their families and society.ConclusionsThis study identified additional domains and items of unmet needs of Korean cancer patients and broadened the understanding of unmet needs among cancer patients
