RESUMO
BACKGROUND: The physical dependence on prescription opioids among cancer survivors remains an under-investigated area, with a scarcity of well-designed prospective studies. METHODS: This single-arm, phase-2 clinical trial in Korea assessed the efficacy and safety of a transdermal buprenorphine patch (TBP) in managing physical dependence on prescription opioids in cancer survivors, as confirmed through the DSM-5 criteria or psychiatric consultation for opioid withdrawal. This study involved a 4-phase treatment protocol of screening, induction/stabilization, discontinuation, and monitoring. The primary outcome was the rate of successful opioid discontinuation, as measured by a negative urine-drug screening at 8 weeks. Key secondary outcomes included the resumption of prescribed opioids, changes in both the Clinical Opioid Withdrawal Scale (COWS) and morphine equivalent daily dose (MEDD), and assessments related to the psychological and physiological aspects of dependence and safety. RESULTS: Thirty-one participants were enrolled. In the intention-to-treat population, the success rate of opioid discontinuation was 58%, with only 2 participants experiencing a resumption of prescribed opioids. Significant reductions were observed in MEDD, which decreased from 98 to 26 mg/day (Pâ <â .001), and COWS scores, which decreased from 5.5 to 2.8 (Pâ <â .001). Desire to use opioids reduced from 7.0 to 3.0 on a 10-point numeric rating scale (Pâ <â .001). Toxicities related to TBP were mild and manageable, without severe precipitated withdrawal symptoms. CONCLUSION: TBP may be considered as an alternative therapeutic option in cancer survivors physically dependent on prescription opioids, especially where sublingual formulations are unavailable.
RESUMO
BACKGROUND: Immune checkpoint inhibitor (ICI) or irinotecan-based chemotherapy is frequently used after failure of second-line paclitaxel plus ramucirumab treatment for patients with locally advanced unresectable or metastatic advanced gastric cancer (AGC). This study aimed to compare the efficacy between ICI and irinotecan-based chemotherapy as third-line treatment in patients with AGC. METHODS: We retrospectively reviewed patients with AGC, whose third-line treatment started between July 2019 and June 2021 at 17 institutions in Korea. The ICI group included patients who received nivolumab or pembrolizumab, and the irinotecan-based chemotherapy group included patients who received irinotecan or FOLFIRI (5-fluorouracil, leucovorin and irinotecan). RESULTS: A total of 363 patients [n = 129 (ICI) and n = 234 (irinotecan-based chemotherapy)] were analyzed. The median progression-free survival was 2.3 and 2.9 months in ICI and irinotecan-based chemotherapy groups, respectively (p = 0.802). The median overall survival (OS) was 5.5 and 6.0 months in ICI and irinotecan-based chemotherapy groups, respectively (p = 0.786). For all patients included in this study, multivariable analysis showed that weight loss, peritoneal metastasis, low serum sodium or albumin, and short duration of second-line treatment were associated with inferior OS (p < 0.05). ICI showed significantly longer OS than irinotecan-based chemotherapy in patients without peritoneal metastasis. Whereas ICI showed significantly shorter OS in patients without PD-L1 expression than irinotecan-based chemotherapy. CONCLUSIONS: No significant difference in survival outcome was observed between ICI and irinotecan-based chemotherapy as third-line treatment for AGC patients. ICI might be preferred for patients without peritoneal metastasis and irinotecan-based chemotherapy for patients with tumors without PD-L1 expression. TRIAL REGISTRATION: This study was registered in the Clinical Trial Registry of Korea ( https://cris.nih.go.kr : KCT 0007732).

We evaluated the safety, tolerability, pharmacokinetics and antitumor activity of barecetamab monotherapy and combination cetuximab therapy in patients with advanced solid cancers, especially head and neck cancer (HNC). Part 1 was a 3 + 3 dose-escalation study in which 15 patients received barecetamab at 1, 3, 5, 10 and 20 mg/kg intravenously (IV) on days 1 and 28 and weekly in patients with advanced solid cancer. Part 2 was a dose-expansion study including two patient groups with advanced HNC, including six patients receiving barecetamab at 20 mg/kg IV every 3 weeks and 12 patients receiving barecetamab and cetuximab (400 mg/m2 on day 1 followed by 250 mg/m2 every week). No dose-limiting toxicities (DLTs) were observed. Maximum serum target engagement was reached with trough levels of doses ≥3 mg/kg IV weekly. Common adverse drug reactions were diarrhea, stomatitis, dermatitis acneiform and decreased appetite. One durable complete response of more than 17 months was observed, and the overall response and disease control rates were 36.4% (4/11) and 81.1% (9/11), respectively, in the combination therapy group. In conclusion, DLT was not observed in barecetamab at 1 to 20 mg/kg. The recommended phase II dose was determined to be 20 mg/kg triweekly. Barecetamab and in cetuximab combination was well tolerated and demonstrated meaningful antitumor effects.

BACKGROUND: Salivary duct carcinoma (SDC) is uncommon but is the most aggressive subtype of salivary gland carcinomas. The high positivity rate for human epidermal growth factor receptor 2 (HER2) led to an investigation of the efficacy of HER2-targeted agents. Docetaxel-PM (polymeric micelle) is a low-molecular-weight, nontoxic, biodegradable, and docetaxel-loaded micellar formulation. Trastuzumab-pkrb is a biosimilar to trastuzumab. METHODS: This was a multicenter, single-arm, open-label phase 2 study. Patients with HER2-positive (immunohistochemistry [IHC] score of ≥2+ and/or HER2/chromosome enumeration probe 17 [CEP17] ratio of ≥2.0) advanced SDCs were enrolled. Patients received docetaxel-PM (75 mg/m2 ) and trastuzumab-pkrb (8 mg/kg in the first cycle and 6 mg/kg in subsequent cycles) every 3 weeks. Primary end point was objective response rate (ORR). RESULTS: A total of 43 patients were enrolled. The best objective responses were partial response in 30 (69.8%) patients and stable disease in 10 (23.3%) patients, leading to an ORR of 69.8% (95% confidence interval [CI], 53.9-82.8) and a disease control rate of 93.0% (80.9-98.5). Median progression-free survival, duration of response, and overall survival were 7.9 (6.3-9.5), 6.7 (5.1-8.4), and 23.3 (19.9-26.7) months, respectively. Patients with HER2 IHC score of 3+ or HER2/CEP17 ratio ≥2.0 demonstrated better efficacies compared to those with HER2 IHC score of 2+. Thirty-eight (88.4%) patients experienced treatment-related adverse events (TRAE). Because of TRAE, nine (20.9%), 14 (32.6%), and 19 (44.2%) patients required temporary discontinuation, permanent discontinuation, or dose reduction, respectively. CONCLUSIONS: The combination of docetaxel-PM and trastuzumab-pkrb demonstrated promising antitumor activity with a manageable toxicity profile in HER2-positive advanced SDC. PLAIN LANGUAGE SUMMARY: Salivary duct carcinoma (SDC) is uncommon but is the most aggressive subtype of salivary gland carcinomas. SDC shares morphological and histological similarities with invasive ductal carcinoma of breast, which led to an investigation of hormonal receptor and human epidermal growth factor receptor 2 (HER2)/neu expression status in SDC. In this study, patients with HER2-positive SDC were enrolled and treated with combination of docetaxel-polymeric micelle and trastuzumab-pkrb. Promising antitumor activities were shown with objective response rate of 69.8%, disease control rate of 93.0%, median progression-free survival of 7.9 months, median duration of response of 6.7 months, and median overall survival of 23.3 months.

BACKGROUND: Immune checkpoint inhibitors (ICIs) have shown significant improvements in patients with advanced non-small cell lung cancer (NSCLC). One of the major issues with ICIs is determining the optimal treatment duration. METHODS: This multicenter, retrospective study analyzed clinical outcomes in patients with NSCLC who completed 2 years of ICI therapy or were treated for more than 6 months and then discontinued ICIs without disease progression at 11 medical centers in Korea between August 2017 and December 2020. RESULTS: Ninety-six patients who completed 2 years of ICIs were reviewed. The median durations of treatment and follow-up were 24.0 and 33.9 months, respectively. The objective response rate (ORR) was 85.4%. The median progression-free survival (PFS) and overall survival (OS) periods were not reached. After completion, the PFS and OS rates were 81.1% and 96.4%, respectively, at 12 months. Forty-three patients were identified who discontinued ICIs without disease progression: 26 (60.5%) for adverse events and 17 (39.5%) for other causes. The median durations of treatment and follow-up were 10.5 and 21.2 months, respectively. The ORR was 90.7%. The median PFS and OS periods were not reached. After discontinuation, the PFS and OS rates were 71.0% and 90.0%, respectively, at 12 months. CONCLUSIONS: A significantly high proportion of patients who completed 2 years of ICI therapy continued to experience long-term PFS. Even if ICIs are discontinued after 6 months in patients without disease progression, they may achieve a durable response and facilitate long-term survival. LAY SUMMARY: The optimal treatment duration for immune checkpoint inhibitors (ICIs) remains to be determined. This study reports the long-term outcomes of patients with non-small cell lung cancer who completed 2 years of ICI therapy or achieved a durable response after the discontinuation of ICIs without disease progression in real-world practice. A significantly high proportion of patients who completed 2 years of ICIs continued to experience long-term progression-free survival. In addition, even if ICIs are discontinued after 6 months in patients without disease progression, they may achieve a durable response and facilitate long-term survival.

BACKGROUND: Polypharmacy is an important issue in the care of older patients with cancer, as it increases the risk of unfavorable outcomes. We estimated the prevalence of polypharmacy, potentially inappropriate medication (PIM) use, and drug-drug interactions (DDIs) in older patients with cancer in Korea and their associations with clinical outcomes. SUBJECTS, MATERIALS, AND METHODS: This was a secondary analysis of a prospective observational study of geriatric patients with cancer undergoing first-line palliative chemotherapy. Eligible patients were older adults (≥70 years) with histologically diagnosed solid cancer who were candidates for first-line palliative chemotherapy. All patients enrolled in this study received a geriatric assessment (GA) at baseline. We reviewed the daily medications taken by patients at the time of GA before starting chemotherapy. PIMs were assessed according to the 2015 Beers criteria, and DDIs were assessed by a clinical pharmacist using Lexi-comp Drug Interactions. We evaluated the association between polypharmacy and clinical outcomes including treatment-related toxicity, and hospitalization using logistic regression and Cox regression analyses. RESULTS: In total, 301 patients (median age 75 years; range, 70-93) were enrolled; the most common cancer types were colorectal cancer (28.9%) and lung cancer (24.6%). Mean number of daily medications was 4.7 (±3.1; range, 0-14). The prevalence of polypharmacy (≥5 medications) was 45.2% and that of excessive polypharmacy (≥10 medications) was 8.6%. PIM use was detected in 137 (45.5%) patients. Clinically significant DDIs were detected in 92 (30.6%) patients. Polypharmacy was significantly associated with hospitalization or emergency room (ER) visits (odds ratio: 1.73 [1.18-2.55], p < .01). Neither polypharmacy nor PIM use showed association with treatment-related toxicity. CONCLUSION: Polypharmacy, PIM use, and potential major DDIs were prevalent in Korean geriatric patients with cancer. Polypharmacy was associated with a higher risk of hospitalization or ER visits during the chemotherapy period. IMPLICATIONS FOR PRACTICE: This study, which included 301 older Korean patients with cancer, highlights the increased prevalence of polypharmacy in this population planning to receive palliative chemotherapy. The prevalence of polypharmacy and excessive polypharmacy was 45.2% and 8.6%, respectively. The prescription of potentially inappropriate medications (PIMs) was detected in 45.5% and clinically significant drug-drug interaction in 30.6% of patients. Given the association of polypharmacy with increased hospitalization or emergency room visits, this study points to the need for increased awareness and intervention to minimize polypharmacy in the geriatric cancer population undergoing chemotherapy. Moreover, specific criteria for establishing PIMs should be adopted for the treatment of older adults with cancer.

BACKGROUND: By investigating treatment patterns and outcomes in locally advanced head and neck squamous cell carcinoma (LA-HNSCC), we aimed at providing valuable insights into the optimal therapeutic strategy for physicians in real-world practice. METHODS: This is a multi-institutional study enrolled the patients with stage III to IVB LA-HNSCC, except for nasopharyngeal carcinoma, from 2004 to 2015 in thirteen referral hospitals capable of multidisciplinary care. RESULTS: A total of 445 LA-HNSCC patients were analyzed. The median age was 61 years (range, 24-89). The primary tumor location was the oropharynx in 191 (43%), oral cavity in 106 (24%), hypopharynx in 64 (14%), larynx in 57 (13%) and other sites in 27 (6%). The most common stage was T2 in 172 (39%), and N2 in 245 (55%). Based on treatment intents, 229 (52%) of the patients received definitive concurrent chemoradiotherapy (CCRT) and 187 (42%) underwent surgery. Approximately 158 (36%) of the study population received induction chemotherapy (IC). Taken together, 385 (87%) of the patients underwent combined therapeutic modalities. The regimen for definitive CCRT was weekly cisplatin in 58%, 3-weekly cisplatin in 28% and cetuximab in 3%. The preferred regimen for IC was docetaxel with cisplatin in 49%, and docetaxel, cisplatin plus fluorouracil in 27%. With a median follow-up of 39 months, one-year and two-year survival rates were 89 and 80%, respectively. Overall survival was not significantly different between CCRT and surgery group (p = 0.620). CONCLUSIONS: In patients with LA-HNSCC, the majority of patients received combined therapeutic modalities. Definitive CCRT, IC then definitive CCRT, and surgery followed by adjuvant CCRT or radiotherapy are the preferred multidisciplinary strategies in real-world practice.

PURPOSE: To investigate the association between quality of life (QOL) and breakthrough cancer pain (BTCP) intensity in patients who met the commonly accepted definition of BTCP. METHODS: This study was a subset analysis of a South Korean multicenter, non-interventional, cross-sectional, nationwide survey. Participants were recruited from March 2016 to December 2017. BTCP was defined as a controlled background pain of less than a numeric rating scale (NRS) of 3 and any flare-up pain intensity. Pain intensity data were collected using the Brief Pain Inventory (BPI), which includes an interference assessment of the affective and physical domains. Patients were categorized by BTCP intensity into mild (NRS 1-3), moderate (4-6), and severe (7-10) groups. RESULTS: Of the 969 screened patients with cancer, 679 had ≤ NRS 3 background pain, of whom 438 completed the BPI. Of these 438 patients, 40, 204, and 194 were in the mild, moderate, and severe BTCP groups, respectively. The median NRS of BTCP was 6.0 (interquartile range = 5.0-8.0). Patients with moderate-severe BTCP had significantly higher interference with daily functioning (IDF) scores than did mild BTCP patients (3.3 vs. 5.7; p < 0.01). Both domains of IDF were significantly hampered proportionally by increased BTCP intensity (p < 0.001). The median total IDF scores of the no, moderate, and severe BTCP groups were 3.3, 5.0, and 6.9, respectively. Furthermore, IDF depended on BTCP intensity, duration, and frequency (p < 0.01) but not on pain type and cause. CONCLUSION: An increase in BTCP intensity is likely to result in IDF, regardless of the cause or type of BTCP.

BACKGROUND: Older patients have increased risk of toxicity from chemotherapy. Current prediction tools do not provide information on cumulative risk. METHODS: Patients aged ≥ 70 years with solid cancer were prospectively enrolled. A prediction model was developed for adverse events (AEs) ≥ Grade 3 (G3), based on geriatric assessment (GA), laboratory, and clinical variables. RESULTS: 301 patients were enrolled (median age, 75 years). Median number of chemotherapy cycles was 4. During first-line chemotherapy, 53.8% of patients experienced AEs ≥ G3. Serum protein < 6.7 g/dL, initial full-dose chemotherapy, psychological stress or acute disease in the past 3 months, water consumption < 3 cups/day, unable to obey a simple command, and self-perception of poor health were significantly related with AEs ≥ G3. A predicting model with these six variables ranging 0-8 points was selected with the highest discriminatory ability (c-statistic= 0.646), which could classify patients into four risk groups. Predicted cumulative incidence of AEs ≥ G3 was discriminated according to risk groups. CONCLUSIONS: This prediction tool could identify the risk of AEs ≥ G3 after chemotherapy and provide information on the cumulative incidence of AEs in each cycle. CLINICAL TRIAL ID: WHO ICTRP number, KCT0001071.

PURPOSE: Patients with advanced cancer may be referred for a palliative care consultation (PC) from a hospital emergency center (EC) or as inpatients. However, research about symptoms and outcomes in patients with advanced cancer who receive PC at the EC is limited. METHODS: We reviewed demographic variables, frequency and intensity of symptoms (using the Edmonton Symptom Assessment Scale (ESAS)), PC interventions, time from admission to PC consultation, hospitalization duration, and discharge destination of 200 advanced cancer patients referred to PC services from the EC ("EC patients") and 200 matched advanced cancer inpatients referred to PC services ("inpatients") from January 1, 2010, through December 31, 2011. RESULTS: The median age for all patients was 56 years (range, 48-64 years); 222 (56 %) patients were female, and 243 (61 %) were white. There were no significant demographic differences between the EC patients and inpatients. The median time from admission to PC was 12 h (range, 7-23 h) for the EC patients and 24 h (24-96 h) for the inpatients (p < 0.0001). For EC patients and inpatients, symptoms at presentation for PC consultation included uncontrolled pain (83 and 45 %, respectively; p < 0.0001), nausea/vomiting/constipation (41 and 19 %, respectively; p < 0.0001), and dyspnea (29 and 19 %, respectively; p = 0.02). The medians and interquartile ranges of baseline symptom intensities for EC patients and inpatients, respectively, were as follows: pain, 7 (5-9) and 5 (2-8) (p < 0.0001); fatigue, 7 (4-8) and 6 (4-8) (p = 0.0517); and sleep, 6 (0-8) and 4 (1-7) (p = 0.1064). At follow-up, improvement was observed in pain (125/238 [53 %]), sleep (59/131 [45 %]), well-being (32/82 [39 %]), fatigue (53/139 [38 %]), anxiety (51/132 [39 %]), appetite (46/132 [35 %]), dyspnea (49/160 [31 %]), nausea (52/170 [31 %]), depression (36/123 [29 %]), and drowsiness (37/126 [29 %]). After PC consultations, discharge/admission destinations for EC patients were as follows: home, 65 (33 %); home hospice, 13 (7 %); inpatient hospice, 8 (4 %); regular hospital floor, 65 (33 %); and PC unit, 46 (23 %). The median duration of hospitalization was 92 h (range, 69-114) for hospitalized EC patients and 125 h (range, 108-142) for inpatients (p < 0.0001). CONCLUSIONS: Referral to PC from the EC led to earlier delivery of PC with subsequent earlier control of symptoms. EC patients who received PC consultations and were hospitalized had shorter hospitalizations than PC referral in the inpatient area. More research is needed to describe the impact of PC services on symptom assessment and management and on goals and plan of care in patients with advanced illness admitted to the EC.

BACKGROUND: The objective of this study was to evaluate the efficacy and safety of dovitinib in patients with adenoid cystic carcinoma (ACC). METHODS: ACC patients with documented disease progression within the past 12 months were eligible. Patients received oral dovitinib (500 mg once daily for 5 consecutive days followed by a 2-day rest every week) until disease progression or unacceptable toxicities. The primary endpoint was the probability of 4-month progression-free survival (PFS). Metabolic response was evaluated with positron emission tomography (PET)/computed tomography (CT) scans performed at the baseline and after 8 weeks of treatment. RESULTS: Between September 2011 and April 2013, 32 patients with metastatic and/or unresectable ACC were enrolled in this prospective, multicenter trial. The 4-month PFS probability was 80.4%, and the median PFS was 6.0 months (95% confidence interval, 4.4-7.6 months). Tumor shrinkage was observed in 22 patients (68.8%), and 1 patient had a confirmed partial response. The disease control rate was 96.9%. Among 26 patients with PET/CT scans both before and after treatment (at 8 weeks), the metabolic activity of ACC was reduced in 13 patients (50.0%), and 5 patients (19.2%) achieved a metabolic partial response, which was defined as a ≥25% reduction in maximum standardized uptake values. Common grade 3 and 4 adverse events were asthenia (50.0%) and neutropenia (25.0%). CONCLUSIONS: Dovitinib shows modest antitumor activity in the treatment of ACC.

BACKGROUND: To the authors' knowledge, only limited data are available regarding the quality of end-of-life care for patients with hematologic malignancies. In this retrospective cohort study, the quality of end-of-life care was compared between patients with hematologic malignancies and those with solid tumors. METHODS: All adult patients who died of advanced cancer between September 1, 2009 and February 28, 2010 while under the care of the study institution were included. The authors collected baseline demographics and end-of-life care indicators, including emergency room visits, hospitalization, intensive care unit admissions, and systemic cancer therapy use within the last 30 days of life. RESULTS: Of a total of 816 decedents, 113 (14%) had hematologic malignancies. In the last 30 days of life, patients with hematologic malignancies were more likely to have emergency room visits (54% vs 43%; P = .03), hospital admissions (81% vs 47%; P < .001), ≥ 2 hospital admissions (23% vs 10%; P < .001), > 14 days of hospitalization (38% vs 8%; P < .001), intensive care unit admissions (39% vs 8%; P < .001) and death (33% vs 4%; P < .001), chemotherapy use (43% vs 14%; P < .001), and targeted therapy use (34% vs 11%; P < .001) compared with patients with solid tumors. Patients with hematologic malignancies were also less likely to have palliative care unit admissions (8% vs 17%; P = .02). The composite score for aggressiveness of care (with 0 indicating the best and 6 indicating the worst) was significantly higher among patients with hematologic malignancies compared with those with solid tumors (median, 2 vs 0; P < .001). On multivariate analysis, hematologic malignancy was found to be a significant factor associated with aggressive end-of-life care (odds ratio, 6.6; 95% confidence interval, 4.1-10.7 [P < .001]). CONCLUSIONS: The results of the current study indicate that patients with hematologic malignancies received more aggressive care at the end of life.

PURPOSE: Cancer pain management guidelines recommend initial treatment with intermediate-strength analgesics such as hydrocodone and subsequent escalation to stronger opioids such as morphine. There are no published studies on the process of opioid rotation (OR) from hydrocodone to strong opioids in cancer patients. Our aim was to determine the opioid rotation ratio (ORR) of hydrocodone to morphine equivalent daily dose (MEDD) in cancer outpatients. PATIENTS AND METHODS: We reviewed the records of consecutive patient visits at our supportive care center in 2011-2012 for OR from hydrocodone to stronger opioids. Data regarding demographics, Edmonton Symptom Assessment Scale (ESAS), and MEDD were collected from patients who returned for follow-up within 6 weeks. Linear regression analysis was used to estimate the ORR between hydrocodone and MEDD. Successful OR was defined as 2-point or 30% reduction in the pain score and continuation of the new opioid at follow-up. RESULTS: Overall, 170 patients underwent OR from hydrocodone to stronger opioid. The median age was 59 years, and 81% had advanced cancer. The median time between OR and follow-up was 21 days. We found 53% had a successful OR with significant improvement in the ESAS pain and symptom distress scores. In 100 patients with complete OR and no worsening of pain at follow-up, the median ORR from hydrocodone to MEDD was 1.5 (quintiles 1-3: 0.9-2). The ORR was associated with hydrocodone dose (r = -.52; p < .0001) and was lower in patients receiving ≥40 mg of hydrocodone per day (p < .0001). The median ORR of hydrocodone to morphine was 1.5 (n = 44) and hydrocodone to oxycodone was 0.9 (n = 24). CONCLUSION: The median ORR from hydrocodone to MEDD was 1.5 and varied according to hydrocodone dose.

BACKGROUND: The aim of this study was to examine the efficacy and safety of everolimus in patients with progressive unresectable adenoid cystic carcinoma (ACC). METHODS: Histologically confirmed ACC patients with documented disease progression within 12 months prior to the study entry were eligible. Everolimus was given at a dose of 10 mg daily until progression or occurrence of unacceptable toxicities. The primary endpoint was a 4-month progression-free survival (PFS). RESULTS: A total of 34 patients were enrolled. The 4-month PFS probability was 65.5% (95% one-sided confidence interval [CI], 47.7 to infinity). Median PFS duration was 11.2 months (95% CI, 3.6 to 15.8). Complete or partial response was not achieved. Twenty-seven (79.4%, 95% CI, 63.2 to 89.6) patients showed stable disease (SD). Tumor shrinkage within SD criteria was observed in 15 patients (44.1%) and SD lasting 6 months was observed in 13 patients (38.2%). Four patients had disease progression. Among the 18 patients with both pre- and post-treatment (at 8 weeks) FDG-PET scans available, 8 patients (44.4%) showed a partial metabolic response, defined as a ≥25% reduction in maximum standardized uptake values (SUVmax). The most common adverse events were stomatitis, anemia, asthenia, and leukopenia. No unexpected everolimus related toxicities were reported. CONCLUSIONS: Everolimus showed promising efficacy and good tolerability in progressive unresectable ACC. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT01152840.

Purpose: This study investigated palliative care physicians' attitudes regarding social issues related to opioid use. Methods: An email survey was sent to 674 physicians who were members of the Korean Society for Hospice and Palliative Care (KSHPC). Results: Data from 66 physicians were analyzed (response rate, 9.8%). About 70% of participants stated that their prescribing patterns were not influenced by social issues related to opioid use, and 90% of participants thought that additional regulations should be limited to non-cancer pain. Under the current circumstances, pain education for physicians is urgently needed, as well as increased awareness among the public. Half of the respondents identified the KSHPC as the primary organization responsible for providing pain education. Conclusion: Palliative care physicians' prescribing patterns were not influenced by social issues related to opioid use, and these issues also should not affect cancer pain control.
RESUMO
BACKGROUND: Lung cancer, especially non-small cell lung cancer (NSCLC), poses a significant health challenge globally due to its high mortality. Afatinib, a second-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), has shown superior efficacy over traditional chemotherapy in NSCLC treatment. However, issues like secondary resistance and adverse effects call for alternative therapies. HAD-B1, comprising 4 herbal medicines, has shown promise in lung cancer treatment in both preclinical and clinical settings. This study assesses the combination of HAD-B1 and Afatinib in advanced NSCLC patients to potentially improve outcomes by addressing the limitations of current EGFR-TKI therapies. METHOD: A randomized, open-label trial evaluated the efficacy and safety of HAD-B1 with Afatinib in 90 EGFR-mutation-positive NSCLC patients. Participants were divided into treatment and control groups, receiving Afatinib with or without HAD-B1. The study focused on the initial dose maintenance rate and disease control rate (DCR) of Afatinib, alongside secondary outcomes like survival rates and quality of life, under continuous safety monitoring. RESULTS: Among the 90 participants, no significant difference was found in initial dose maintenance (60.98% in the treatment group vs 52.50% in the control, P = .4414) or DCR (80.49% vs 90.00%, P = .2283). Secondary outcomes like PFS, TTP, and OS showed no notable differences. However, physical functioning significantly improved in the treatment group (P = .0475, PPS group). The control group experienced higher rates of adverse events of special interest and adverse drug reactions (P = .01), suggesting HAD-B1 with Afatinib might enhance physical function without increasing adverse effects. CONCLUSION: Combining HAD-B1 with Afatinib potentially improves quality of life and reduces adverse events in advanced NSCLC patients. Further research is necessary to confirm the long-term benefits of this combination therapy, aiming to advance NSCLC treatment outcomes.

OBJECTIVES: This study aimed to investigate whether genetic alterations in PI3KCA and the cell cycle pathways influence the efficacy of durvalumab, an immune checkpoint inhibitor, in patients with head and neck squamous cell carcinoma (HNSCC) who had previously failed platinum-based treatment. MATERIALS AND METHODS: We obtained data from a phase II umbrella trial of patients with HNSCC who failed platinum-based treatment (TRIUMPH, NCT03292250). Patients receiving durvalumab treatment comprised those with PIK3CA alterations (Group A), those with cell cycle pathway alterations such as CDKN2A (Group B), and those with no druggable genetic alterations (Group C). We analyzed the overall response rate (ORR), progression-free survival (PFS), and overall survival (OS) in each group and evaluated the potential predictive factors for durvalumab. RESULTS: We analyzed the data of 87 patients: 18, 12, and 57 in groups A, B, and C, respectively. The ORRs were 27.8 %, 8.3 %, and 15.8 % in Groups A, B, and C, respectively (P = 0.329), and the median PFS for each group was 2.3, 1.6, and 1.7 months, respectively, with no significant differences between the groups (P = 0.24). Notably, patients with lower neutrophil-lymphocyte ratio (NLR) (≤5.8) had longer PFS (median, 2.8 vs 1.6 months, P < 0.001), while those with lower platelet-lymphocyte ratio (PLR) (≤491.2) exhibited longer PFS (median, 1.8 vs 1.2 months, P < 0.001). CONCLUSION: Durvalumab's efficacy was similar, irrespective of the presence of PIK3CA or cell cycle pathway genetic alterations in patients with platinum-resistant HNSCC. The NLR and PLR may be promising predictive biomarkers.

PURPOSE: A precise oncologic approach for head and neck squamous cell carcinoma (HNSCC) is necessary. We performed a genomic profile-based umbrella trial for the patients with platinum-refractory recurrent and/or metastatic HNSCC. METHODS: In this multicenter, open-label, single-arm phase II trial, we performed targeted next-generation sequencing (NGS). Patients were assigned to each treatment arm on the basis of their matching genomic profiles: arm 1, alpelisib, a PIK3CA inhibitor; arm 2, poziotinib, an epidermal growth factor receptor/HER2 inhibitor; arm 3, nintedanib, an fibroblast growth factor receptor inhibitor; and arm 4, abemaciclib, a CDK4/6 inhibitor. If there was no matching target, patients were allocated to arm 5, duvalumab ± tremelimumab, anti-PD-L1/cytotoxic T-cell lymphocyte-4 inhibitor. When progressive disease (PD) occurred in arms 1-4, cross over to arm 5 was allowed. The primary end point was disease control rate (DCR) in arm 1 and overall response rate (ORR) in arms 2-5 by investigator assessment. RESULTS: Between October 2017 and August 2020, 203 patients were enrolled, including crossover. In arm 1, the ORR was 21.2% and DCR was 65.6%. The ORR was 0% for arm 2, 42.9% for arm 3, 0% for arm 4, and 15.6% for arm 5. In the case of PD with durvalumab, tremelimumab was added, and the ORR for durvalumab + tremelimumab was 2.2%. The median progression-free survival was 3.4, 3.2, 5.6, 1.6, and 1.7 months for each arm, respectively. The median overall survival was 12.4, 6.1, 11.1, 9.1, and 12.7 months, respectively. Overall, the toxicity profiles were manageable, and there were no treatment-related deaths. CONCLUSION: To our knowledge, this study is the first biomarker-driven umbrella trial for platinum-refractory HNSCC using matched molecular targeted agents. We found that NGS-based genomic phenotyping was methodologically feasible and applicable.

PURPOSE: In the treatment of non-small-cell lung cancer (NSCLC) with a driver mutation, the role of anti-PD-(L)1 antibody after tyrosine kinase inhibitor (TKI) remains unclear. This randomized, open-label, multicenter, phase III study evaluates the efficacy of atezolizumab plus bevacizumab, paclitaxel, and carboplatin (ABCP ) in EGFR- or ALK-mutated NSCLC that progressed before TKI therapy. MATERIALS AND METHODS: We compared the clinical efficacy of ABCP followed by maintenance therapy with atezolizumab plus bevacizumab with pemetrexed plus carboplatin or cisplatin (PC) followed by pemetrexed maintenance. The primary end point was progression-free survival (PFS). RESULTS: A total of 228 patients with activating EGFR mutation (n = 215) or ALK translocation (n = 13) were enrolled from 16 sites in the Republic of Korea and randomly assigned at 2:1 ratio to either ABCP (n = 154) or PC arm (n = 74). The median follow-up duration was 26.1 months (95% CI, 24.7 to 28.2). Objective response rates (69.5% v 41.9%, P < .001) and median PFS (8.48 v 5.62 months, hazard ratio [HR], 0.62 [95% CI, 0.45 to 0.86]; P = .004) were significantly better in the ABCP than PC arm. PFS benefit increased as PD-L1 expression increased, with an HR of 0.47, 0.41, and 0.24 for PD-L1 ≥1%, ≥10%, and ≥50%, respectively. Overall survival was similar between ABCP and PC arm (20.63 v 20.27 months, HR, 1.01 [95% CI, 0.69 to 1.46]; P = .975). The safety profile of the ABCP arm was comparable with that previously reported, with no additional safety signals, but higher rates of treatment-related adverse events were observed compared with the PC arm. CONCLUSION: To our knowledge, this study is the first randomized phase III study to demonstrate the clinical benefit of anti-PD-L1 antibody in combination with bevacizumab and chemotherapy in patients with EGFR- or ALK-mutated NSCLC who have progressed on relevant targeted therapy.

BACKGROUND/AIM: This study investigated the treatment patterns and prognosis of patients with metastatic or unresectable colorectal cancer (mCRC) treated with chemotherapy with targeting agents. PATIENTS AND METHODS: This longitudinal multicenter study included 963 patients with mCRC who were treated in Korea between 2016 and 2020. Treatment patterns and efficacy were compared according to the mutation status and clinical factors. RESULTS: As first-line therapy, most of the patients (83.5%) received FOLFOX plus bevacizumab (35.4%), followed by FOLFIRI plus bevacizumab (18.8%), FOLFIRI plus cetuximab (17.0%), and FOLFOX plus cetuximab (12.3%). Bevacizumab was the most frequent agent (78.8%) combined with chemotherapy in RAS-mutated CRC, while cetuximab (57.2%) in RAS wild-type CRC. Cetuximab was frequently combined with a doublet regimen in patients with left-sided CRC than in those with right-sided CRC (34.4% vs. 16%). As second-line therapy, most patients (63.4%) also received doublet regimens with bevacizumab, and FOLFIRI plus aflibercept was administered in 15.1%. The objective response rate with FOLFIRI plus cetuximab was significantly higher in patients with left-sided CRC than in those with right-sided CRC (59.2% vs. 30.8%, p=0.008) and marginally higher in patients with RAS wild-type CRC than in those with RAS-mutated CRC (55.6% vs. 0.0%, p=0.092). Progression-free survival (PFS) with FOLFOX plus bevacizumab was significantly shorter than that with FOLFIRI plus bevacizumab (p=0.030) in RAS-mutated CRC, whereas there were no significant differences between regimens in RAS wild-type CRC. CONCLUSION: In patients with unresectable metastatic colorectal cancer, doublet chemotherapy with targeting agents is the most common therapy and efficacy depends on the mutation status as well as clinical factors.
