RESUMO
Cancer genomic medicine using next-generation sequencers has been developing. However, the number of patients who could receive genomically matched therapy is limited because off-label use or patient-oriented compassionate use was not permitted under National Health Insurance in Japan. To improve patient drug accessibility, we initiated a biomarker-based basket-type clinical trial (NCCH1901) in October 2019 under patient-proposed healthcare services. We listed the drugs that had high medical needs but were not covered by National Healthcare Insurance. Then we included these drugs before patient proposal so that they could access off-label drugs soon after they had the results of CGP tests. All drugs were provided free of charge by pharmaceutical companies. The objective was to administer off-label drugs and to collect efficacy and safety data for these drugs. The primary endpoint was the response rate based on the best overall response for up to 16 weeks. As of January 31, 2022, we included 18 drug cohorts and 295 patients were treated in this study. The most common cancer was brain tumor, followed by carcinoma of endocrine organs and colorectal cancer. BRAF mutations and ERBB2 amplifications were the frequent genomic abnormalities to be enrolled. This study was one way to access off-label drugs, and contributed significantly to providing treatment opportunities for patients in Japan.

In Japan, comprehensive genomic profiling (CGP) tests have been reimbursed under the national health care system for solid cancer patients who have finished standard treatment. More than 50,000 patients have taken the test since June 2019. We performed a nation-wide questionnaire survey between March 2021 and July 2022. Questionnaires were sent to 80 designated Cancer Genomic Medicine Hospitals. Of the 933 responses received, 370 (39.7%) were web based and 563 (60.3%) were paper based. Most patients (784, 84%) first learned about CGP tests from healthcare professionals, and 775 (83.1%) gave informed consent to their treating physician. At the time of informed consent, they were most worried about test results not leading to novel treatment (536, 57.4%). On a scale of 0-10, 702 respondents (75.2%) felt that the explanations of the test result were easy to understand (7 or higher). Ninety-one patients (9.8%) started their recommended treatment. Many patients could not receive recommended treatment because no approved drugs or clinical trials were available (102/177, 57.6%). Ninety-eight patients (10.5%) did not wish their findings to be disclosed. Overall satisfaction with the CGP test process was high, with 602 respondents (64.5%) giving a score of 7-10. The major reason for choosing 0-6 was that the CGP test result did not lead to new treatment (217/277, 78.3%). In conclusion, satisfaction with the CGP test process was high. Patients and family members need better access to information. More patients need to be treated with genomically matched therapy.

BACKGROUND: Precision medicine has transformed cancer treatment by focusing on personalized approaches based on genomic abnormalities. However, comprehensive genomic profiling (CGP) and access to targeted therapies are limited in Japan. This study investigates the BELIEVE trial, which aims to improve drug accessibility for patients with actionable genetic abnormalities through off-label drug administration. METHODS: The BELIEVE trial is a platform trial with a single master protocol, conducted under the Clinical Trials Act and the patient-proposed health services (PPHS) scheme. Eligible patients with solid tumors exhibiting actionable alterations were enrolled, and CGP tests covered by national health insurance were employed. Treatment selection, study drugs from collaborating pharmaceutical companies, and treatment schedules adhered to predefined protocols. Primary and secondary endpoints were evaluated, and statistical analysis was conducted based on patient response rates. RESULTS: The BELIEVE trial offered treatment opportunities for patients with relapse/refractory disease who lacked standard therapies or clinical trial options. This study addresses unmet medical needs and contributes to the establishment of precision medicine systems. Similar trials like NCI-MATCH and TAPUR are being conducted globally. The BELIEVE trial provides a platform for off-label drug administration, collects essential clinical data, and contributes to drug approval applications. CONCLUSION: The BELIEVE trial provides hope for patients with actionable genetic abnormalities by facilitating access to targeted therapies through off-label drug administration. It establishes a regulatory framework and promotes collaboration between industry and academia by expanding organ-specific and cross-organ biomarker-based treatments.

BACKGROUND: Programmed cell death-1 (PD-1) blockade improves survival in patients with advanced esophageal squamous cell carcinoma (ESCC). However, the efficacy of taxanes after exposure to PD-1 blockade remains unclear in patients with advanced ESCC. METHODS: We retrospectively analyzed the clinical outcomes of advanced ESCC patients treated with taxanes (paclitaxel or docetaxel) with/without prior exposure to PD-1 blockade (Exposed /Naïve group) at National Cancer Center Hospital from June 2016 to December 2020. RESULTS: Ninety-nine patients (Exposed group, n = 32; Naïve group, n = 67) were included. The objective response rate (ORR) of the Exposed group was significantly higher than that of the Naïve group (37.5% vs. 13.4%, p = 0.009). The median progression-free survival was similar between the Exposed and Naïve groups (3.8 vs. 2.8 months, HR 1.12, 95% CI 0.65-1.86, p = 0.66). PD-1 blockade exposure independently predicated higher ORR to taxanes in multivariate analysis. Grade ≥ 3 adverse events were comparable between the Exposed and Naïve groups (45.8% vs. 40.3%, p = 0.64). CONCLUSIONS: Taxanes following PD-1 blockade in advanced ESCC showed a higher ORR but similar PFS compared to taxanes without prior PD-1 exposure.
RESUMO
BACKGROUND: Chemotherapy consisting of 5-fluorouracil, leucovorin, oxaliplatin, and docetaxel is the standard perioperative treatment for resectable esophageal adenocarcinoma and esophagogastric junctional adenocarcinoma (EGJ-AC) in Western countries. Meanwhile, preoperative chemotherapy consisting of docetaxel, cisplatin, and 5-fluorouracil (DCF) has been developed for esophageal squamous cell carcinoma in Japan. However, there are few reports on the safety and efficacy of preoperative DCF for resectable EGJ-AC in the Japanese population. METHODS: Patients with histologically confirmed resectable EGJ-AC who received preoperative DCF (docetaxel 70 mg/m2 and cisplatin 70 mg/m2 on day 1 and continuous infusion of 5-fluorouracil 750 mg/m2/day on days 1-5 every 3 weeks with a maximum of three cycles) between January 2015 and April 2020 were retrospectively evaluated. We assessed the rates of completion of ≥ 2 courses of DCF and R0 resection, histopathological response, progression-free survival (PFS), overall survival (OS), and adverse events. RESULTS: Thirty-two patients were included. Median follow-up was 28.7 (range, 5.2-70.8) months and median age was 63 (range, 42-80) years. Twenty-one patients (66%) had a performance status of 0. The proportions of clinical stage IIA/IIB/III/IVA/IVB disease were 3%/0%/44%/44%/9%, respectively. The treatment completion rate was 84%. A histopathological response of grade 1a/1b/2/3 was obtained in 58%/26%/13%/3% of cases. Median PFS was 40.7 months (95% confidence interval 11.8-NA). Median OS was not reached (80.8% at 3 years). Grade ≥ 3 adverse events were observed in 63% of cases (neutropenia, 44%; febrile neutropenia, 13%). No treatment-related deaths occurred. CONCLUSIONS: Preoperative DCF for resectable EGJ-AC was well tolerated and has promising efficacy.

Comprehensive genomic profiling (CGP) tests have been nationally reimbursed in Japan since June 2019 under strict restrictions, and over 46,000 patients have taken the test. Core Hospitals and Designated Hospitals host molecular tumor boards, which is more time-consuming than simply participating in them. We sent a questionnaire to government-designated Cancer Genomic Medicine Hospitals, including all 12 Core Hospitals, all 33 Designated Hospitals, and 117 of 188 Cooperative Hospitals. The questionnaire asked how much time physicians and nonphysicians spent on administrative work for cancer genomic medicine. For every CGP test, 7.6 h of administrative work was needed. Physicians spent 2.7 h/patient, while nonphysicians spent 4.9 h/patient. Time spent preparing for molecular tumor boards, called Expert Panels, was the longest, followed by time spent participating in Expert Panels. Assuming an hourly wage of ¥24,000/h for physicians and ¥2800/h for nonphysicians, mean labor cost was ¥78,071/patient. On a monthly basis, more time was spent on administrative work at Core Hospitals compared with Designated Hospitals and Cooperative Hospitals (385 vs. 166 vs. 51 h/month, respectively, p < 0.001). Consequently, labor cost per month was higher at Core Hospitals than at Designated Hospitals and Cooperative Hospitals (¥3,951,854 vs. ¥1,687,167 vs. ¥487,279/month, respectively, p < 0.001). Completing a CGP test for a cancer patient in Japan is associated with significant labor at each hospital, especially at Core Hospitals. Streamlining the exchange of information and simplifying Expert Panels will likely alleviate this burden.

Postoperative delirium is an important issue in cancer patients, affecting surgical outcomes and the quality of life. Ramelteon is a melatonin receptor agonist with high affinity for MT1 and MT2 receptors. Clinical trials and observational studies in Japan, including in surgical cancer patients, have shown efficacy of ramelteon in delirium prevention, with no serious safety concerns. However, clinical trials from the USA have reported conflicting results. A Japanese phase II study investigated the efficacy and safety of ramelteon for delirium prevention following gastrectomy in patients aged ≥75 years, with findings suggesting the feasibility of a phase III trial. The aim of this multi-centre, double-blind, randomized placebo-controlled phase III trial is to evaluate the effectiveness and safety of oral ramelteon for postoperative delirium prevention in cancer patients aged ≥65 years as advanced medical care. The trial protocol is described here.

BACKGROUND: Aberrant fibroblast growth factor receptor (FGFR) signaling can substantially influence oncogenicity. Despite that FGFR gene abnormality is often detected by cancer genome profiling tests, there is no tumor-agnostic approval yet for these aberrations. E7090 (tasurgratinib) is an orally available selective tyrosine kinase inhibitor of FGFR1-3. Specific FGFR alterations were previously reported to be highly sensitive to E7090 based on a high-throughput functional evaluation method, called mixed-all-nominated-mutants-in-one (MANO) method, narrowing down the most promising targets. This trial was focused on the alterations identified by the MANO method and was performed under the nationwide large registry network for rare cancers in Japan (MASTER KEY Project). METHODS/DESIGN: This single-arm Phase 2 trial was designed to evaluate the safety and efficacy of E7090 in patients with advanced or recurrent solid tumors harboring FGFR alterations. Three cohorts were set based on the type of FGFR alterations and the results of MANO method. A maximum of 45 patients will be enrolled from 5 institutions over 2.5 years. E7090 will be administered once daily as an oral single agent in 28-day cycles. The primary endpoint is the objective overall response rate; whereas, the secondary endpoints include progression-free survival, overall survival, disease control rate, safety, duration of response, and time to response. Ethics approval was granted by the National Cancer Center Hospital Certified Review Board. Patient enrollment began in June 2021. DISCUSSION: A unique investigator-initiated multicenter Phase 2 trial was designed based on the results of preclinical investigation aiming to acquire the approval of E7090 for solid tumors harboring FGFR gene alterations. The findings may serve as a novel model for the development of tumor-agnostic molecular targeted therapies against rare genetic abnormalities. TRIAL REGISTRATION: Japan Registry of Clinical Trial: jRCT2031210043 (registered April 20, 2021) ClinicalTrials.gov: NCT04962867 (registered July 15, 2021).

In 2017, the Japan Society of Clinical Oncology (JSCO) published the JSCO Clinical Practice Guidelines 2017 for Fertility Preservation in Childhood, Adolescent, and Young Adult Cancer Patients. These were the first Japanese guidelines to address issues of oncofertility. In this field of medicine, sustained close cooperation between oncologists and reproductive specialists is essential from the diagnosis of cancer until many years after completion of cancer treatment. These JSCO guidelines were intended to guide multidisciplinary medical staff in considering the availability of fertility preservation options and to help them decide whether to provide fertility preservation to childhood, adolescent, and young adult cancer patients before treatment starts, with the ultimate goal of improving patient survivorship. The guidelines are presented as Parts 1 and 2. This article (Part 1) summarizes the goals of the guidelines and the methods used to develop them and provides an overview of fertility preservation across all oncology areas. It includes general remarks on the basic concepts surrounding fertility preservation and explanations of the impacts of cancer treatment on gonadal function by sex and treatment modality and of the options for protecting/preserving gonadal function and makes recommendations based on 4 clinical questions. Part 2 of these guidelines provides specific recommendations on fertility preservation in 8 types of cancer (gynecologic, breast, urologic, pediatric, hematologic, bone and soft tissue, brain, and digestive).

The Japan Society of Clinical Oncology (JSCO) published the "JSCO Clinical Practice Guidelines 2017 for Fertility Preservation in Childhood, Adolescent, and Young Adult Cancer Patients" in 2017. This was the first guideline in cancer reproductive medicine in Japan. In the field of cancer reproductive medicine, close cooperation between an oncologist and a physician for reproductive medicine is important from before treatment initiation until long after treatment. The guideline takes into consideration disease specificity and provides opinions from the perspective of oncologists and specialists in reproductive medicine that are in line with the current state of the Japanese medical system. It is intended to serve as a reference for medical staff in both fields regarding the availability of fertility preservation therapy before the start of cancer treatment. Appropriate use of this guideline makes it easier to determine whether fertility preservation therapy is feasible and, ultimately, to improve survivorship in childhood, adolescent, and young adult cancer patients. In this article (Part 2), we describe details by organ/system and also for pediatric cancer.

Comprehensive genomic profiling has been approved for use in patients with advanced solid tumours; however, it is only indicated in advanced solid tumour patients without available standard chemotherapeutic treatment or those who have completed standard treatments in Japan, and there are no available data on the clinical feasibility and utility of comprehensive genomic profiling in treatment-naive patients. This multicentre, single-arm, prospective study aims to evaluate the feasibility and utility of the OncoGuide NCC Oncopanel System in treatment-naive patients with six advanced major malignancies: non-small cell lung cancer, breast cancer, gastric cancer, colon cancer, pancreatic cancer and biliary tract cancer (NCCH1908). This study (study cohort) will be compared with the other prospective observational study (control cohort), which enrols patients not receiving comprehensive genomic profiling prior to initial systemic treatment. A total of 200 patients will be enrolled in the study over 21 months. This study has been registered in the UMIN Clinical Trials Registry (www.umin.ac.jp/ctr/) (UMIN000040743). CLINICAL TRIAL REGISTRATION: This study, initiated in June 2020, has been registered in the UMIN Clinical Trials Registry (www.umin.ac.jp/ctr/) (registration number: UMIN000040743). We plan to enrol a total of 200 patients over a period of 21 months.

BACKGROUND: To promote precision oncology in clinical practice, the Japanese Society of Medical Oncology, the Japanese Society of Clinical Oncology, and the Japanese Cancer Association, jointly published "Clinical practice guidance for next-generation sequencing in cancer diagnosis and treatment" in 2017. Since new information on cancer genomic medicine has emerged since the 1st edition of the guidance was released, including reimbursement for NGS-based multiplex gene panel tests in 2019, the guidance revision was made. METHODS: A working group was organized with 33 researchers from cancer genomic medicine designated core hospitals and other academic institutions. For an impartial evaluation of the draft version, eight committee members from each society conducted an external evaluation. Public comments were also made on the draft. The finalized Japanese version was published on the websites of the three societies in March 2020. RESULTS: The revised edition consists of two parts: an explanation of the cancer genomic profiling test (General Discussion) and clinical questions (CQs) that are of concern in clinical practice. Particularly, patient selection should be based on the expectation that the patient's post-test general condition and organ function will be able to tolerate drug therapy, and the optimal timing of test should be considered in consideration of subsequent treatment plans, not limited to treatment lines. CONCLUSION: We expect that the revised version will be used by healthcare professionals and will also need to be continually reviewed in line with future developments in cancer genome medicine.

Metabolic reprogramming, including the Warburg effect, is a hallmark of cancer. Indeed, the diversity of cancer metabolism leads to cancer heterogeneity, but accurate assessment of metabolic properties in tumors has not yet been undertaken. Here, we performed absolute quantification of the expression levels of 113 proteins related to carbohydrate metabolism and antioxidant pathways, in stage III colorectal cancer surgical specimens from 70 patients. The Warburg effect appeared in absolute protein levels between tumor and normal mucosa specimens demonstrated. Notably, the levels of proteins associated with the tricarboxylic citric acid cycle were remarkably reduced in the malignant tumors which had relapsed after surgery and treatment with 5-fluorouracil-based adjuvant therapy. In addition, the efficacy of 5-fluorouracil also decreased in the cultured cancer cell lines with promotion of the Warburg effect. We further identified nine and eight important proteins, which are closely related to the Warburg effect, for relapse risk and 5-fluorouracil benefit, respectively, using a biomarker exploration procedure. These results provide us a clue for bridging between metabolic protein expression profiles and benefit from 5-fluorouracil adjuvant chemotherapy.

Background Ramucirumab (RAM) plus solvent-based (sb)-paclitaxel (PTX) is the standard second-line chemotherapy for advanced gastric cancer (AGC). The subset analysis of the ABSOLUTE trial, which confirmed non-inferiority of weekly nanoparticle albumin-bound (nab)-PTX to weekly sb-PTX, suggested that nab-PTX might have better efficacy than sb-PTX in patients with peritoneal metastasis. We retrospectively evaluated the efficacy and safety of RAM plus sb-PTX and nab-PTX in patients with peritoneal metastasis of AGC. Methods AGC patients who received RAM plus sb-PTX or nab-PTX as second-line chemotherapy from June 2015 to February 2019 were included in the study. Overall survival (OS), progression-free survival (PFS), response rate, and safety were assessed. Results A total of 128 patients were included in this study (93 in the RAM plus sb-PTX group and 35 in the RAM plus nab-PTX group). PFS was 4.1 months in the RAM plus sb-PTX group and 4.6 months in the RAM plus nab-PTX group (HR 0.90; 95%CI 0.58-1.41, p = 0.643). OS was 8.9 months in the RAM plus sb-PTX group and 11.4 months in the RAM plus nab-PTX group (HR 0.95; 95%CI 0.56-1.62, p = 0.847). A total of 62 and 31 patients had peritoneal metastasis in the RAM plus sb-PTX and the RAM plus nab-PTX groups, respectively. RAM plus nab-PTX showed a slightly longer survival compared to RAM plus sb-PTX in patients with peritoneal metastasis (PFS 5.8 vs 3.5 months, HR 0.66; 95% CI 0.40-1.10, p = 0.109). Conclusion This study suggests that RAM plus nab-PTX might be a more effective treatment for peritoneal metastasis of AGC.

BACKGROUND: Fluoropyrimidine plus platinum, followed by paclitaxel (PTX) plus ramucirumab is a recommended treatment strategy for advanced gastric cancer (AGC). We investigated how peripheral neuropathy (PN), induced by platinum in first-line chemotherapy, affected the tolerability of second-line chemotherapy with PTX (2nd-PTX). METHODS: The subjects were AGC patients who received second-line chemotherapy with PTX (2nd-PTX) after the failure of platinum-based chemotherapy between March 2015 and June 2018. We retrospectively reviewed PN severity, and dose reduction and/or discontinuation due to PN during 2nd-PTX, and compared the cumulative incidence of grade 2 PN between the two groups according to first-line chemotherapy containing oxaliplatin (L-OHP) or cisplatin (CDDP). RESULTS: The L-OHP and CDDP groups consisted of 50 patients each. PN severity before 2nd-PTX was grade 1/2 in 46/12% of patients in the L-OHP group, and 100/0% in the CDDP group. The worst grades of chemotherapy-induced PN during 2nd-PTX were grades 1/2/3 in 40/34/14% of patients in the L-OHP group, and 36/18/0% in the CDDP group. Median time to grade 2 PN after starting second-PTX was 2.5 months in the L-OHP group and 8.6 months in the CDDP group (hazard ratio 3.34, p = 0.002). The frequencies of a PN-related dose reduction and/or discontinuation of PTX were 18% in the L-OHP group and 8% in the CDDP group (p = 0.234). CONCLUSIONS: The severity of PN and tolerability of 2nd-PTX may be affected by first-line chemotherapy with L-OHP or CDDP for AGC.

Neuroendocrine tumors (NET) are rare tumors for which somatostatin analogs (SSA) are used not only for symptom control due to a functioning tumor, but also for the disease control of unresectable NET. The efficacy of SSA for midgut NET has been verified by previous studies, but insufficient evidence exists for SSA treatment of NET in the foregut and hindgut (F/H-NET). The aim of this retrospective study was to evaluate the efficacy of SSA for unresectable F/H-NET. Patients with unresectable F/H-NET treated with SSA between February 2011 and August 2017 at our hospital were retrospectively reviewed. Parameters of efficacy were progression-free survival (PFS), overall survival, objective response rate (ORR), and adverse events. Twelve cases with unresectable F/H-NET were extracted from our database. With a median follow-up time of 25.9 months, the median PFS was 13.6 months. Two- and 3-year survival rates were 87.5 and 62.5%, respectively. The ORR was 8.3%, and the disease control rate was 75%. Serious adverse events were not observed. Subgroup analysis, including G1/G2, and hepatic tumor load, which is the volume of NET liver metastases, did not reveal a difference in PFS. The efficacy and safety of SSA for F/H-NET seemed similar to that found in the PROMID study, highlighting its relevance for the treatment of this disease.

BACKGROUND: Recent studies have shown that immune-related adverse events (irAEs) caused by immune checkpoint inhibitors were associated with clinical benefit in patients with melanoma or lung cancer. In advanced gastric cancer (AGC) patients, there have been few reports about the correlation between irAEs and efficacy of immune checkpoint inhibitors. In this study, we retrospectively investigated the correlation between irAEs and efficacy in AGC patients treated with nivolumab. METHODS: The subjects of this study were AGC patients received nivolumab monotherapy between January 2015 and August 2018. IrAEs were defined as those AEs having a potential immunological basis that required close follow-up, or immunosuppressive therapy and/or endocrine therapy. We divided the patients who received nivolumab into two groups based on occurrence of irAEs; those with irAEs (irAE group) or those without (non-irAE group). We assessed the efficacy in both groups. RESULTS: Of the 65 AGC patients that received nivolumab monotherapy, 14 developed irAEs. The median time to onset of irAEs was 30.5 days (range 3-407 days). Median follow-up period for survivors was 32 months (95% CI, 10.8 to 34.5). The median progression-free survival was 7.5 months (95% CI, 3.6 to 11.5) in the irAE group and 1.4 months (95% CI, 1.2 to 1.6) in the non-irAE group (HR = 0.11, p < 0.001). The median overall survival was 16.8 months (95% CI, 4.4 to not reached) in the irAE group and 3.2 months (95% CI, 2.2 to 4.1) in the non-irAE group (HR = 0.17, p < 0.001). Multivariate analysis demonstrated that number of metastatic sites ≥2 (HR = 2.15; 95% CI, 1.02 to 4.54), high ALP level (HR = 2.50; 95% CI, 1.27 to 4.54), and absence of irAEs (HR = 9.54, 95% CI, 3.34 to 27.30 for yes vs. no) were associated with a poor prognosis. The most frequent irAEs was diarrhea/colitis (n = 5). Grade 3 adverse events were observed in 6 patients; hyperglycemia (n = 2), diarrhea/colitis (n = 1), adrenal insufficiency (n = 1), aspartate aminotransferase increased (n = 1), peripheral motor neuropathy (n = 1). There were no grade 4 or 5 adverse events related to nivolumab. CONCLUSIONS: Development of irAEs was associated with clinical benefit for AGC patients receiving nivolumab monotherapy.

BACKGROUND: Definitive chemoradiotherapy is one of the treatment options for locally advanced esophageal cancer with curative intent. Esophagitis and pharyngitis are well-known adverse events that occur during chemoradiotherapy, but gastric mucosal injury has been less frequently reported compared to mucositis. Importantly, gastric mucosal injury is not well known, hard to manage, and sometimes fatal. Hence, we examined the clinical characteristics and the incidence of gastric mucosal injury after CRT for esophageal cancer. METHODS: The medical records of patients who received definitive chemoradiotherapy combined with 5-fluorouracil and cisplatin for stage II/III (nonT4) esophageal squamous cell carcinoma from January 2001 to December 2010 at our institute were reviewed retrospectively. RESULTS: We investigated 256 patients in whom, data for endoscopic abdomen examinations were both before and after CRT were available. Gastric mucosal damage was observed in 90 patients (35%) (grade 1/2/3 = 69/18/3). One of the possible risk factors identified in this study was the irradiation dose to abdomen. Compared to patients with cervical esophagus-upper thoracic esophagus tumor location, patients with middle thoracic esophagus-abdominal esophagus tumor location were more likely to develop gastric mucosal damage, although there was no statistically significant difference. CONCLUSIONS: It is important to consider gastric mucosal injury in patients who receive CRT, particularly when the irradiation field includes stomach.

PURPOSE: The purpose of this study was to investigate the utility of surveillance after definitive chemoradiotherapy (dCRT) in patients with squamous cell carcinoma. METHODS: Patients who underwent dCRT for stage II/III (excluding T4) esophageal squamous cell carcinoma were analyzed. First failures following complete response were classified into luminal relapse (LR), regional relapse (RR), distant metastasis (DM), new cancer diagnosed by esophagogastroduodenoscopy (NC-E), and new cancer other than NC-E (NC-O). We focused on LR, RR, and NC-E, and analyzed their frequency, timings and survival outcomes after local treatments. RESULTS: Among 302 patients treated with dCRT, 204 achieved complete response. The number of patients who recurred with LR, RR, DM, NC-E, and NC-O were 28 (14% of 204), 13 (6%), 39 (19%), 34 (17%), and 16 (8%). Ninety-three percent of LRs were diagnosed within 3 years after dCRT, and all RRs were diagnosed within 2 years. Annual odds of NC-E did not decrease over time. Twenty-three patients with LR, 6 with RR, and 32 with NC-E underwent local treatment, and their median overall survivals were 49.2, 19.5, and 108.9 months. CONCLUSION: Surveillance with esophagogastroduodenoscopy may be important in the first 3 years after dCRT to detect LR and to detect NC-E beyond 3 years.

PURPOSE: The RADIANT-4 randomized phase 3 study demonstrated significant prolongation of median progression-free survival (PFS) with everolimus compared to placebo (11.0 [95% CI 9.2-13.3] vs. 3.9 [95% CI 3.6-7.4] months) in patients with advanced, progressive, nonfunctional gastrointestinal (GI) and lung neuroendocrine tumors (NET). This analysis specifically evaluated NET patients with GI and unknown primary origin. METHODS: Patients in the RADIANT-4 trial were randomized 2:1 to everolimus 10 mg/day or placebo. The effect of everolimus on PFS was evaluated in patients with NET of the GI tract or unknown primary site. RESULTS: Of the 302 patients enrolled, 175 had GI NET (everolimus, 118; placebo, 57) and 36 had unknown primary (everolimus, 23; placebo, 13). In the GI subset, the median PFS by central review was 13.1 months (95% CI 9.2-17.3) in the everolimus arm versus 5.4 months (95% CI 3.6-9.3) in the placebo arm; the hazard ratio (HR) was 0.56 (95% CI 0.37-0.84). In the unknown primary patients, the median PFS was 13.6 months (95% CI 4.1-not evaluable) for everolimus versus 7.5 months (95% CI 1.9-18.5) for placebo; the HR was 0.60 (95% CI 0.24-1.51). Everolimus efficacy was also demonstrated in both midgut and non-midgut populations; a 40-46% reduction in the risk of progression or death was reported for patients in the combined GI and unknown primary subgroup. Everolimus had a benefit regardless of prior somatostatin analog therapy. CONCLUSIONS: Everolimus showed a clinically meaningful PFS benefit in patients with advanced progressive nonfunctional NET of GI and unknown primary, consistent with the overall RADIANT-4 results, providing an effective new standard treatment option in this patient population and filling an unmet treatment need for these patients.
