RESUMEN

BACKGROUND: This study evaluated the non-inferiority of dexamethasone (DEX) on day 1, with sparing on days 2-4 in cisplatin-based chemotherapy. METHODS: Patients with malignant solid tumors who were treated with cisplatin (≥50 mg/m²) were randomly assigned (1:1) to receive either DEX on days 1-4 (Arm D4) or DEX on day 1 (Arm D1) plus palonosetron, NK-1 RA, and olanzapine (5 mg). The primary endpoint was complete response (CR) during the delayed (24-120 h) phase. The non-inferiority margin was set at -15%. RESULTS: A total of 281 patients were enrolled, 278 of whom were randomly assigned to Arm D4 (n = 139) or Arm D1 (n = 139). In 274 patients were included in the efficacy analysis, the rates of delayed CR in Arms D4 and D1 were 79.7% and 75.0%, respectively (risk difference -4.1%; 95% CI -14.1%-6.0%, P = 0.023). However, patients in Arm D1 had significantly lower total control rates during the delayed and overall phases, and more frequent nausea and appetite loss. There were no significant between-arm differences in the quality of life. CONCLUSION: DEX-sparing is an alternative option for patients receiving cisplatin; however, this revised administration schedule should be applied on an individual basis after a comprehensive evaluation.

RESUMEN

BACKGROUND: Pembrolizumab alone or combined with chemotherapy is the standard of care for first-line treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) with positive programmed death-ligand 1 combined positive scores. However, data on second-line chemotherapy following pembrolizumab are scarce. METHODS: A single-center, retrospective study was conducted to determine the efficacies of pembrolizumab and pembrolizumab plus chemotherapy as first-line treatments and the efficacy of second-line chemotherapy for patients with R/M HNSCC who were refractory or intolerant to first-line treatment. RESULTS: Fifty-four patients were treated with pembrolizumab, and 29 received second-line therapy, with 27 opting for cetuximab-containing regimens. The median progression-free survival (PFS), overall survival (OS), and PFS on next-line therapy for first-line treatment were 4.7 (95% confidence interval [CI], 2.1-8.7), 22.1 (95% CI, 12.6-not reached), and 15.6 months (95% CI, 9.7-not reached) in the pembrolizumab group and 5.4 (95% CI, 3.3-6.8), 15.8 (95% CI, 8.6-not reached), and 13.7 months (95% CI, 8.1-not reached) in the pembrolizumab plus chemotherapy group, respectively. The overall response rate and median PFS for second-line treatment were 48.3% (95% CI, 30.4-67.0) and 6.1 months (95% CI, 2.30-8.84). The median OS for patients who received second-line treatment was 18.4 months, which was superior to the median OS of 6.0 months for patients who received the best supportive care (log-rank p = 0.10). CONCLUSION: This study indicates that cetuximab-containing second-line chemotherapy can improve outcomes in R/M HNSCC, even after first-line therapy failure or intolerance.

RESUMEN

BACKGROUND: Criticisms have emerged that cancer medicines offer modest benefits at increasingly high prices. Reimbursement decisions made by health technology assessment (HTA) agencies have become a complex endeavour for cancer medicines. Most high-income countries (HICs) use HTA criteria to identify high-value medicines for reimbursement under public drug coverage plans. We compared HTA criteria specific for cancer medicines in economically similar HICs, to understand how these criteria contribute to reimbursement decisions. METHODS: We did an international, cross-sectional analysis in collaboration with author investigators across eight HICs, from the Group of Seven (known as G7; Canada, England, France, Germany, Italy, and Japan) and Oceania (Australia and New Zealand). Publicly available data from HTA agency reports and official documentation were extracted and analysed between Aug 15, 2021, and July 31, 2022. We collected data pertaining to the decision-making criteria used by the national HTA agency; HTA reimbursement status for 34 medicine-indication pairs corresponding to 15 unique US top-selling cancer medicines; and HTA reimbursement status for 18 cancer medicine-indication pairs (13 unique medicines) with minimal clinical benefit (score of 1 on the European Society of Medical Oncology Magnitude of Clinical Benefit Scale). Descriptive statistics were used to compare HTA decision criteria and drug reimbursement recommendations (or for Germany and Japan, final reimbursement status) across the eight countries. FINDINGS: Therapeutic impact related to clinical outcomes of the new medicine was a uniform criterion across the eight countries, whereas quality of evidence (under the remit of therapeutic impact assessment) and equity were infrequently cited criteria. Only the German HTA agency mandated that surrogate endpoints be validated in therapeutic impact assessment. All countries except Germany included formal cost-effectiveness analyses within HTA reports. England and Japan were the only countries that specified a cost-effectiveness threshold. Of the 34 medicine-indication pairs corresponding to US top-selling cancer medicines, Germany reimbursed the maximum (34 [100%]), followed by Italy (32 [94%] recommended for reimbursement), Japan (28 [82%] reimbursed), Australia, Canada, England, and France (27 [79%] recommended for reimbursement), and New Zealand (12 [35%] recommended for reimbursement). Of the 18 cancer medicine-indication pairs with marginal clinical benefit, Germany reimbursed 15 (83%) and Japan reimbursed 12 (67%). France recommended nine (50%) for reimbursement, followed by Italy (seven [39%]), Canada (five [28%]), and Australia and England (three [17%] each). New Zealand did not recommend any medicine-indications with marginal clinical benefit for reimbursement. Considering the overall cumulative proportion across the eight countries, 58 (21%) of 272 indications for the US top-selling medicines and 90 (63%) of 144 marginally beneficial medicine-indications were not recommended for reimbursement or reimbursed. INTERPRETATION: Our findings indicate discordance in public reimbursement decisions across economically similar countries, despite overlapping HTA decision criteria. This suggests a need for improved transparency around the nuances of the criteria to ensure improved access to high-value cancer medicines, and deprioritisation of low-value cancer medicines. Health systems have opportunities to improve their HTA decision-making processes by learning from the systems in other countries. FUNDING: None.

RESUMEN

BACKGROUND: In this phase Ib study MODURATE, we optimized the dosing schedule and tested the efficacy and safety of trifluridine/tipiracil, irinotecan, and bevacizumab in patients with metastatic colorectal cancer with fluoropyrimidine and oxaliplatin treatment failure. METHODS: We included a dose escalation (3 + 3 design) and an expansion cohort. Patients were administered trifluridine/tipiracil (25-35 mg/m2 twice daily, days 1-5), irinotecan (150-180 mg/m2, day 1), and bevacizumab (5 mg/kg, day 1) every 2 weeks. The recommended phase II dose (RP2D) in the dose escalation cohort was administered to at least 15 patients in both cohorts combined. RESULTS: Twenty-eight patients were enrolled. Five dose-limiting toxicities were observed. RP2D was defined as trifluridine/tipiracil 35 mg/m2, irinotecan 150 mg/m2, and bevacizumab 5 mg/kg. Of 16 patients who received RP2D, 86% (14/16) experienced grade ≥3 neutropenia without febrile neutropenia. Dose reduction, delay, and discontinuation occurred in 94%, 94%, and 6% of patients, respectively. Three patients (19%) showed partial response and 5 had stable disease for >4 months, with a median progression-free and overall survival of 7.1 and 21.7 months, respectively. CONCLUSION: Biweekly trifluridine/tipiracil, irinotecan, and bevacizumab administration may have moderate antitumor activity with high risk of severe myelotoxicity in previously treated patients with metastatic colorectal cancer [UMIN Clinical Trials Registry (UMIN000019828) and Japan Registry of Clinical Trials (jRCTs041180028)].

RESUMEN

BACKGROUND: A regional cancer hospital has been identified to be crucial in the management of malignancies of undefined primary origin (MUO) and cancer of unknown primary (CUP). This hospital primarily consists of oncologists with expertise in CUP, pathologists, and interventional radiologists. Early consultation or referral of MUO and CUP to a cancer hospital is deemed important. METHODS: This study retrospectively collected and analyzed the clinical, pathological, and outcome data of all patients (n = 407) referred to the Aichi Cancer Center Hospital (ACCH) in Japan over an 8-year period. RESULTS: In total, 30% of patients were referred for a second opinion. Among 285 patients, 13% had non-neoplastic disease or confirmed primary site and 76% had confirmed CUP (cCUP), with 29% of cCUP being identified as favorable risk. In 155 patients with unfavorable-risk CUP, 73% had primary sites predicted by immunohistochemistry (IHC) and distribution of metastatic sites, whereas 66% of them received site-specific therapies based on the predicted primary sites. The median overall survival (OS) was found to be poor in patients with MUO (1 month) and provisional CUP (6 months). In addition, the median OS of 206 patients with cCUP treated at the ACCH was 16 months (favorable risk, 27 months; unfavorable risk, 12 months). No significant difference was noted in OS between patients with non-predictable and predictable primary-sites (13 vs 12 months, p = 0.411). CONCLUSION: The outcome of patients with unfavorable-risk CUP remains to be poor. Site-specific therapy based on IHC is not recommended for all patients with unfavorable-risk CUP.

RESUMEN

OBJECTIVES: Patients often struggle with their financial situation during cancer treatment due to treatment-related costs or loss of income. This resulting negative effect is called financial toxicity, which is a known as a side effect of cancer care. This study aimed to evaluate the association between financial toxicity and health-related quality of life among patients with gynecologic cancer using validated questionnaires. METHODS: In this multicenter study, patients with gynecologic cancer receiving anti-cancer drug treatment for > 2 months were recruited. Patients answered the COmprehensive Score for Financial Toxicity (COST) tool, EORTC-QLQ-C30, disease-specific tools (EORTC-QLQ-OV28/CX24/EN24), and EQ-5D-5L. Spearman's rank correlation coefficient was used to determine associations. RESULTS: Between April 2019 and July 2021, 109 cancer patients completed the COST questionnaire. The mean COST score was 19.82. Strong associations were observed between financial difficulty (r = - 0.616) in the EORTC-QLQ-C30 and body image (r = 0.738) in the EORTC-QLQ-CX24, while weak associations were noted between the global health status/quality of life (r = 0.207), EQ-5D-5L index score (r = 0.252), and several function and symptom scale scores with the COST score. CONCLUSIONS: Greater financial toxicity was associated with worse health-related quality of life scores, such as financial difficulty in gynecologic cancer patients and body image in cervical cancer patients as strong associations, and weakly associated with general health-related quality of life scores and several function/symptom scales.

RESUMEN

BACKGROUND: Nivolumab is recommended for patients with advanced esophageal squamous cell carcinoma (aESCC) refractory or intolerant to fluoropyrimidine- and platinum-based chemotherapy regardless of the tumor proportion score (TPS). However, the role of combined positive score (CPS) in predicting nivolumab efficacy remains unclear. We aimed to study whether TPS or CPS is a more suitable biomarker for predicting nivolumab efficacy in these patients. METHODS: We retrospectively collected data from patients with aESCC treated with fluoropyrimidines and platinum and subsequently received nivolumab monotherapy between January 1, 2014 and September 15, 2020. Next, we evaluated the efficiencies of TPS and CPS in predicting the clinical response to nivolumab using PD-L1 IHC 22C3 pharmDx assay. RESULTS: This study included 50 patients (CPS groups: ≥ 10/1-10/ < 1, n = 24/18/8, respectively; TPS groups, ≥ 10%/1%-10%/ < 1%, n = 17/8/25, respectively). The median progression-free survival was 3.2, 2.5, and 1.5 months in the ≥ 10, 1-10 [hazard ratio (HR) vs. CPS of ≥ 10 group, 1.01; p = 0.98; adjusted HR, 1.33; p = 0.56], and < 1 CPS groups (HR vs. CPS of ≥ 10 group, 3.44; p = 0.006; adjusted HR, 1.67; p = 0.41), respectively. For the patients with CPS of ≥ 10/1-10/ < 1 and TPS of ≥ 10%/1%-10%/ < 1%, the objective response rate was 30%/25%/0% and 36%/0%/19% and the disease control rate was 60%/50%/12% (p = 0.06) and 65%/40%/38% (p = 0.30), respectively. CONCLUSIONS: This study suggests that a CPS of < 1 is not a strong predictor of efficacy but can predict the absence of response to nivolumab in patients with aESCC.

RESUMEN

OBJECTIVE: Financial toxicity is a financial burden of cancer care itself, which leads to worse quality of life and higher mortality and is considered an adverse effect. The COmprehensive Score for financial Toxicity (COST) tool is a patient-reported outcome measurement used to evaluate financial toxicity. We aimed to validate the internal consistency and reproducibility of the COST tool in patients with gynecologic cancer. METHODS: In this multicenter study covering the period April 2019 to July 2021, using the COST tool in Japan, patients diagnosed with ovarian, cervical, or endometrial cancer receiving systemic anti-cancer drug therapy for more than 2 months were eligible. Patients with no out-of-pocket costs for direct medical costs were excluded. The patients answered the initial test and a retest, which was completed from 2 to 14 days after the initial test. Internal consistency and reproducibility were assessed using Cronbach's alpha and intraclass correlation coefficient (ICC), respectively. Cronbach's alpha ≥0.8 indicates good internal consistency, and ICC ≥0.8 is highly reliable. RESULTS: A total of 112 patients (ovarian: 50, cervical: 26, endometrial: 36) responded to the initial test, and 89 patients answered the retest from 2 to 14 days after the initial test. The median patient age was 58 (range, 28-78) years. The median COST score was 19. Cronbach's alpha showed good internal consistency at 0.83 (95% CI 0.78 to 0.87). The ICC at 0.850 (95% CI 0.777 to 0.900) showed high reliability. CONCLUSIONS: The COST tool has good internal consistency and reliable reproducibility in patients with gynecologic cancer in Japan. The COST tool quantifies financial toxicity in the insurance system, where patients have limited out-of-pocket direct medical costs. The results support the use of the COST tool in patients with gynecologic cancer.

RESUMEN

An inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal neoplasm that typically develops in the lungs and seldom in the head and neck region. It is often related to the anaplastic lymphoma kinase (ALK) fusion gene. Crizotinib, a first-generation ALK inhibitor, has been shown to have a notable response in patients with ALK-positive IMT. Here, we report the first case of a 46-year-old man with IMT harboring a novel SQSTM1-ALK fusion gene who demonstrated marked response to alectinib. The patient presented a right neck mass (5-cm diameter) that progressively enlarged and expanded to the upper mediastinum. ALK-rearranged IMT was diagnosed after complete tumor resection. Spindle cells displayed diffuse cytoplasmic staining for ALK on immunohistochemistry. A fluorescence in situ hybridization analysis revealed the translocation of a part of the ALK gene locus at chromosome 2p23. FoundationOne CDx™ assay identified an SQSTM1-ALK gene fusion. After a year, right cervical, subclavian, and mediastinal lymph node metastases, considered unresectable, developed. Notably, the patient exhibited a marked response to alectinib treatment and has sustained for 17 months following systemic therapy initiation without significant adverse events. This report highlights the possibility of alectinib being a reasonable option for advanced IMT with the SQSTM1-ALK fusion.

RESUMEN

Financial toxicity (FT) has a negative impact on quality of life (QOL) and survival of patients with cancer. However, FT has not been well defined and unlike the Common Terminology Criteria for Adverse Events (CTCAE) for physical toxicities, valid methods to quantify FT have not been well established. Hence, further studies into the methods to properly measure and quantify the risks of FT are important. The COmprehensive Score for financial Toxicity (COST) score has been validated as a useful tool for measuring FT among patients with cancer in the US. However, the health insurance system in the US is unique and thus, COST score's feasibility and validity in other countries with public universal health care in place is unknown. Thus, we aimed to evaluate the feasibility of COST questionnaire as a tool to evaluate FT among patients with cancer in a different health care system of Japan where universal public health insurance system exists. We performed a prospective survey to ascertain the feasibility of using COST questionnaire (Japanese version) to evaluate FT in Japanese patients with advanced solid cancer who were receiving chemotherapy. The survey showed some Japanese patients experienced meaningful FT during chemotherapy.

RESUMEN

Background This study evaluated the safety, tolerability, pharmacokinetics, immunogenicity and antitumor activity of single and multiple doses of nivolumab in Japanese patients with malignant solid tumors. Subjects and Methods This was an open-label, dose-escalation study in 17 patients with advanced solid tumors with a life expectancy of ≥3 months. Patients were observed for 3 weeks after a single dose of nivolumab at 1, 3, 10 or 20 mg/kg, then received the same dose of nivolumab every 2 weeks until unacceptable toxicity or disease progression occurred. This study included a maximum dose of 20 mg/kg, which is the highest dose of nivolumab evaluated to date. The maximum dose was 10 mg/kg in previous studies. Results The commonest adverse drug reaction was lymphopenia, which occurred in 10 (58.8%) patients, including two (11.8%) with Grade ≥3 events. No dose-limiting toxicities (DLTs) were observed up to the maximum dose of 20 mg/kg. The area under the concentration-time curve from time 0 to the last measurable concentration was linear up to 20 mg/kg. The maximum concentration showed dose-dependency up to 10 mg/kg, but not between 10 and 20 mg/kg. One durable complete response and two partial responses were observed. Conclusions Nivolumab at doses of 1-20 mg/kg was not associated with DLTs, and it was generally well tolerated at doses of up to 20 mg/kg in Japanese patients with advanced solid tumors.

RESUMEN

OBJECTIVE: Ramucirumab is a recombinant human immunoglobulin G1 monoclonal antibody targeting the vascular endothelial growth factor receptor-2. The aim of this phase 1 study was to evaluate the safety and tolerability of ramucirumab monotherapy in Japanese patients with advanced solid tumors. METHODS: Patients with solid tumors who had not responded to standard therapy or for whom no standard therapy was available received escalating doses of ramucirumab, administered once every 2 (Q2W) or 3 (Q3W) weeks. The primary objective was to establish the safety and pharmacokinetic profiles of ramucirumab. Secondary and exploratory objectives included assessment of immunogenicity and antitumor activity. ClinicalTrials.gov: NCT01005355. RESULTS: Fifteen patients were treated with ramucirumab at a dose of 6 mg/kg Q2W (N = 3), 8 mg/kg Q2W (N = 6) or 10 mg/kg Q3W (N = 6). There were no dose-limiting toxicities and the maximum tolerated dose was not reached. The most common ramucirumab-related adverse events were headache, pyrexia, hypertension and increased aspartate aminotransferase. Following single-dose administration of ramucirumab, there appeared to be a dose-proportional increase in maximum observed drug concentration but not in area under the curve. Treatment-emergent anti-ramucirumab antibodies were not detected in any patient. CONCLUSIONS: Ramucirumab monotherapy was well tolerated and feasible at the doses and schedules used in this study population of Japanese patients with advanced solid tumors.

RESUMEN

With the increase in incidence and mortality of breast cancer in low-income countries (LICs), the question of whether LICs should promote breast cancer screening for early detection has gained tremendous importance. Because LICs have limited financial resources, the value of screening must be carefully considered before integrating screening programs into national healthcare system. Mammography-the most commonly used screening tool in developed countries-reduces breast cancer-specific mortality among women of age group 50-69, but the evidence is not so clear for younger women. Further, it does not reduce the overall mortality. Because the women in LICs tend to get breast cancer at younger age and are faced with various competing causes of mortality, LICs need to seriously evaluate whether mammographic screening presents a good value for the investment. Instead, we suggest a special module of clinical breast examination that could provide similar benefits at a very low cost. Nevertheless, we believe that LICs would obtain a much greater value for their investment if they promote primary prevention by tobacco cessation, healthier food and healthier lifestyle campaigns instead.

RESUMEN

RO4987655 is an oral and selective inhibitor of MEK, a key enzyme of the mitogen-activated protein kinase (MAPK) signaling pathway. This phase I dose-escalation study of RO4987655 in Japanese patients with advanced solid tumors aimed to determine maximum tolerated dose (MTD) and to evaluate safety, pharmacokinetics (PK), pharmacodynamics (PD), and anti-tumor activity. Patients received a single dose of RO4987655 (1, 2, 4, 5, or 6.5 mg) followed by continuous once-daily dosing (1, 2, or 4 mg QD) or twice-daily dosing (4, 5, or 6.5 mg BID) in 28-day cycles. A 3 + 3 dose-escalation design was used. PD was evaluated by pERK inhibition in peripheral blood mononuclear cells (PBMCs). In dose-escalation, 25 patients were enrolled. After the MTD was determined, a further six patients were administered the MTD for further confirmation of safety. MTD was determined as 8 mg/day (4 mg BID) due to a total of four dose-limiting toxicities (DLTs) of grade 3 creatine phosphokinase (CPK) elevation (2 DLTs each in 10 mg/day and 13 mg/day). Most commonly related adverse events included dermatitis acneiform, CPK elevation, and eye disorders. Plasma concentration of RO4987655 appeared to increase in a dose-proportional manner with a plasma half-life of 4.32 to 21.1 h. Following multiple dose administration, a steady-state condition was reached by Cycle 1 Day 8. The inhibitory effects of RO4987655 on pERK in PBMCs increased in a dose-dependent manner. One esophageal cancer patient had confirmed partial response and seven patients showed progression-free survival for longer than 16 weeks. The MTD of RO4987655 for Japanese patients was determined as 8 mg/day (4 mg BID).

RESUMEN

Opioid-induced constipation (OIC) is a very troublesome, difficult to manage and a nearly universal complication of chronic opioid use to control pain associated with advanced illness. Some studies have reported that OIC is so intolerable in some patients that they skip their opioid medications and bear pain instead of OIC. Laxatives have commonly been used as a prophylaxis and treatment of OIC but they are frequently ineffective because the commonly available laxatives do not target the underlying mechanism of OIC, which is the blockade of peripheral mu-receptors. Recently, there have been a number of advances in the treatment of OIC, which any physician involved with opioid-prescribing discipline should be aware of. This review will update the new options and strategies available for treating OIC along with the relevant clinical trials. Finally, this review also provides a recommendation on the preferred way to approach a patient with OIC in the modern era as well as highlight on the importance of doctor-patient communication in this setting.

RESUMEN

Information on the financial toxicity experienced by Japanese patients with metastatic renal cell carcinoma (mRCC) is lacking, even though Japan has its own unique public health insurance system. Thus, a web-based survey was conducted to evaluate the financial toxicity experienced by Japanese mRCC patients using the COmprehensive Score for financial Toxicity (COST) tool. This study enrolled Japanese patients who underwent, or were undergoing, systemic therapy for mRCC. The outcomes evaluated were the distribution of COST scores, the correlation between COST and quality of life (QOL) assessed by the Functional Assessment of Cancer Therapy-General (FACT-G) scale, and demographic factors associated with financial toxicity. The median (range) COST score was 19.0 (3.0-36.0). The Pearson correlation coefficient for COST and FACT-G total scores was 0.40. Univariate analysis revealed that not having private health insurance and lower household income per year were significantly associated with lower COST scores. Multivariate analyses showed that age < 65 years and not having private health insurance were significantly associated with lower COST scores. This study revealed that Japanese mRCC patients experience adverse financial impacts even under the universal health insurance coverage system available in Japan, and financial toxicity negatively affects their QOL.

RESUMEN

OBJECTIVE: To achieve patient-centricity in metastatic renal cell carcinoma (mRCC) treatment, it is essential to clarify the differences in perspectives between patients and physicians. This cross-sectional analysis of a web survey aimed to clarify the differences in expectations and concerns between mRCC patients and physicians regarding systemic mRCC therapy in Japan. METHODS: Surveys from 83 patients and 165 physicians were analyzed. RESULTS: The top three most significant differences in expectations of systemic therapy between patients and physicians (patient-based physician value) were "Chance of achieving treatment-free status" (-30.1%, p < 0.001), "Longer survival" (+25.8%, p < 0.001), and "Chance of eliminating all evidence of disease" (-25.6%, p < 0.001). The top three most significant differences in concerns for systemic therapy between patients and physicians (patient-based physician value) were "Lack of efficacy" (+36.1%, p < 0.001), "Lack of knowledge of treatment" (-28.2%, p < 0.001), and "Daily activities affected by side effects" (+22.3%, p < 0.001). Diarrhea, fatigue/malaise, and nausea/vomiting were patients' most distressing adverse events; 50.6% of patients had difficulty telling their physicians about adverse events such as fatigue, anxiety, and depression. CONCLUSIONS: This study demonstrated a gap between patients with mRCC and physicians in their expectations and concerns for systemic therapy. Japanese patients with mRCC suffer from a number of adverse events, some of which are not shared with physicians. This study highlights the importance of communicating well with patients in clinical practice to achieve patient-centricity in systemic treatment for mRCC.

RESUMEN

BACKGROUND/AIM: Although gemcitabine plus cisplatin (GC) prolongs survival in patients with recurrent or metastatic nasopharyngeal carcinoma (R/M NPC) compared with fluorouracil plus cisplatin, no study has evaluated the efficacy and safety of GC in nonendemic regions, including Japan, yet. Therefore, we assessed the safety and efficacy of GC in Japanese patients with R/M NPC. PATIENTS AND METHODS: We retrospectively reviewed patients with R/M NPC who received GC treatment at the Aichi Cancer Center Hospital from January 2017 to March 2020. The main eligibility criteria were histologically confirmed NPC, Eastern Cooperative Oncology Group performance status (ECOG PS) of 0-2, and locally recurrent disease unsuitable for local treatment or metastatic disease. The regimen was administered every 3 weeks (gemcitabine, 1,000 mg/m2 on days 1 and 8; cisplatin, 80 mg/m2 on day 1). RESULTS: Fourteen patients (median age, 58 years) were included in the study. Two patients had an ECOG PS of 2 and 11 exhibited nonkeratinizing histology. Of the eight patients with measurable lesions, one exhibited complete response and seven exhibited partial response, with an objective response rate of 75%. Median progression-free survival and overall survival were 7.7 and 24.2 months, respectively. Common grade 3 or 4 adverse events included neutropenia (64%), thrombocytopenia (14%), and febrile neutropenia (14%). The median relative dose intensity of gemcitabine and cisplatin was 62% and 60%, respectively. No treatment-related deaths occurred. CONCLUSION: The GC regimen demonstrates promising activity and is tolerable in Japanese patients with R/M NPC.

RESUMEN

The combination of trifluridine/tipiracil hydrochloride (FTD/TPI) plus ramucirumab has demonstrated clinical activity in patients with advanced gastric cancer (AGC). We evaluated the efficacy and safety of this combination compared with those of FTD/TPI monotherapy in patients with AGC. We retrospectively reviewed data of patients with AGC who received FTD/TPI plus ramucirumab or FTD/TPI monotherapy as third- or later-line treatment. This study included 36 patients treated with FTD/TPI plus ramucirumab and 70 patients receiving FTD/TPI monotherapy. The objective response rate (ORR) and disease control rate (DCR) were 25.8% and 58.1%, respectively, in the FTD/TPI plus ramucirumab group and 5.0% and 38.3%, respectively, in the FTD/TPI group (ORR, P = 0.007; DCR, P = 0.081). The median progression-free survival (PFS) was significantly longer in the FTD/TPI plus ramucirumab group (median PFS, 2.9 vs. 1.8 months; hazard ratio [HR]: 0.52; P = 0.001). A numerical survival benefit was also observed (median overall survival, 7.9 months vs. 5.0 months; HR: 0.68, P = 0.089). In the multivariate analysis, PFS was significantly longer in the FTD/TPI plus ramucirumab group than in the FTD/TPI monotherapy group (HR: 0.61, P = 0.030). The incidence of febrile neutropenia was higher in the FTD/TPI plus ramucirumab group than in the FTD/TPI group (13.8% vs. 2.9%); however, no new safety signals were identified. Compared with FTD/TPI monotherapy, FTD/TPI plus ramucirumab offers clinical benefits with acceptable toxicity in heavily pretreated patients with AGC. Further investigation via randomized trials is warranted to confirm these findings.
