    Abstract: e21553 Background: The systemic treatment for advanced BRAF-mutant melanoma includes BRAF/MEK inhibitors (BRAF/MEKi), anti-PD-1 monotherapy (aPD1), and the combination of nivolumab plus ipilimumab (NIVO/IPI). Several studies have demonstrated favorable survival benefits for those treated with immunotherapy upfront. Most of these studies, however, were conducted among Caucasian-dominant cohorts; evidence for Asian patients is limited. Therefore, our objective was to assess the efficacy of first-line therapies for Asian patients in a real-world setting. Methods: We retrospectively collected the clinical data of Asian patients with advanced BRAF-mutant melanoma treated with first-line BRAF/MEKi, aPD1, or NIVO/IPI from 26 institutions in Japan. Clinical outcomes were determined by assessing the objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) by first-line therapies. Kaplan‐Meier curves and log‐rank tests, as well as multivariable Cox proportional hazard models were used to estimate survival probabilities. Results: We identified 316 Asian patients treated with first-line BRAF/MEKi (n = 224), aPD1 (n = 59), or NIVO/IPI (n = 33) between 2016 and 2021. At baseline, the median age of the patients in each treatment arm was 63, 62, and 54, respectively (p = 0.053). The ORR in the first-line therapy was 69%, 29%, and 27%, respectively (p 〈 0.001). With a median follow-up of 18.9 months, the median PFS was 16.2, 5.6, and 6.4 months (p = 0.001); and the median OS was 36.9, 37.9 months, and not reached (p = 0.386), respectively. In a multivariable analysis, the predictive factors of short PFS were first-line therapy with aPD1 (HR, 2.44; 95%CI, 1.70-3.50, p 〈 0.001) or NIVO/IPI (1.73; 1.06–2.83, p = 0.029), BRAF V600K (p = 0.031), ECOG PS ≥2 (p = 0.011), elevated lactate dehydrogenase (LDH) levels (p = 0.001), and M1a/M1c/M1d stages (p = 0.036/ 〈 0.001/ 〈 0.001, respectively). Predictive factors of short OS were BRAF V600K (p = 0.042), ECOG PS ≥2 (p = 0.001), elevated LDH levels (p 〈 0.001), and M1c/M1d stages (both p 〈 0.001). The OS did not differ significantly by first-line therapies between BRAF/MEKi, aPD1 (1.52; 0.98–2.34, p = 0.061), and NIVO/IPI (0.63; 0.31–1.27, p = 0.194). Conclusions: Although upfront NIVO/IPI showed the longest OS numerically, its superiority over BRAF/MEKi in Asian patients seems to be modest compared with Caucasian patients. Because upfront BRAF/MEKi showed an OS that was comparable with that of aPD1, BRAF/MEKi remains an active first-line therapy option, especially for those who are not amenable to take the high risk of immune-related toxicities.

    A randomized phase II/III trial comparing hepatectomy followed by mFOLFOX6 with hepatectomy alone for liver metastasis from colorectal cancer: JCOG0603 study.
    American Society of Clinical Oncology (ASCO) ; 2020

    Abstract: 4005 Background: The role of adjuvant chemotherapy after hepatectomy is controversial for liver only metastases from colorectal cancer (LM). Current recommendations for oxaliplatin-containing adjuvant regimen (FOLFOX) for LM are based on extrapolation of the results of the EORTC intergroup trial 40983, which showed that perioperative FOLFOX confirmed a progression-free survival benefit but did not affect overall survival (OS) in LM patients. We conducted a randomized controlled trial to determine if adjuvant modified FOLFOX (mFOLFOX) is superior to hepatectomy alone for LM. Methods: Eligible patients aged 20-75 years who had histologically proven colorectal adenocarcinoma with an unlimited number of LM were randomly assigned (1:1) to receive either adjuvant mFOLFOX6 (oxaliplatin 85mg/m 2 , l-LV 200 mg/m 2 , 5-FU bolus 400 mg/m 2 and 2400mg/m 2 over 48 h), for 12 cycles after surgery (CTX arm), or surgery alone (S alone arm). When treatment compliance after 9 courses of CTX was as high as expected in phase II, the registration was continued in phase III. The primary endpoint of phase III was disease-free survival (DFS), and the secondary endpoints were OS, toxicity, and sites of relapse. The planned sample size was 150 patients (pts) per arm, with a one-sided alpha of 5%, and 80% power detecting a 5y-DFS difference of 12% (25% with S alone vs. 37% with CTX). Results: Between Mar. 2007 and Jan. 2019, 300 patients were randomized. 151 pts were allocated to CTX, and 149 pts to S alone. When the third interim analysis of phase III was performed in Dec. 2019, the DSMC recommended the early termination of the trial because a statistically significant difference in terms of DFS but the futility in terms of OS was found. With a median follow-up period of 54 months for disease-free surviving patients, the 3y-DFS was 52.1% (95% CI 43.2 – 60.2) with CTX and 41.5% (33.2 – 49.6) with S alone (hazard ratio 0.63 [0.45 – 0.89], one-sided p = 0.002 〈 0.0163 for the one-sided alpha level at the interim analysis). However, the 3y-OS was 86.6% (79.2-91.4) with CTX and 92.2% (86.0 – 95.8) with S alone (hazard ratio 1.35 [0.84 – 2.19]). The 5y-OS was 69.5% (59.6-77.5) with CTX and 83.0% (74.5-88.9) with S alone. Median OS after recurrence was 38.4 months in the CTX arm and 87.6 in the S alone arm. Conclusions: DFS did not correlate with OS for LM. Postoperative chemotherapy with mFOLFOX6 improves DFS but worsens OS over surgery alone due to more deaths after recurrence in the CTX arm. Adjuvant mFOLFOX is not beneficial to patients after hepatectomy for LM. Clinical trial information: UMIN000000653 .

    Abstract: e21579 Background: Extramammary Paget's disease (EMPD) is a rare skin cancer that develops in the vulva, anus, and axilla. The incidence rate of EMPD is 0.13 per 100,000 population/year in Caucasians and 0.28 in Asians; thus, it is more frequent in Asians. Although distant metastases have been reported to occur in 10%-20% of all cases of EMPD, standard systemic chemotherapy for advanced EMPD has not been established worldwide. Retrospective studies conducted thus far have been insufficient due to their small sample sizes. Furthermore, there are no reports comparing the effectiveness of multiple treatments. To establish a standard treatment for advanced EMPD, prospective clinical trials are necessary, and we are planning a prospective clinical trial. As a pilot study, we investigated a large sample of patients with advanced EMPD and analyzed the efficacy of systemic chemotherapies. Methods: Patients with advanced EMPD who were treated in 16 Japanese institutions during 2011-2022 were evaluated. The efficacy of each treatment was estimated by determining the objective response rate (ORR) or progression-free survival (PFS) and overall survival (OS) using the Kaplan-Meier analysis. Multivariable analysis was performed to account for potential confounding factors, such as age, sex, and performance status (PS). A total of 204 patients were enrolled, of which 164 (80.4%) patients were treated as follows: Docetaxel hydrate (DOC), n = 108 (52.9%); tegafur/ gimeracil/ oteracil potassium (S-1)/DOC, n = 16 (7.8%); fluorouracil/cisplatin (FP), n = 26 (12.8%); fluorouracil/epirubicin/carboplatin/vincristine/mitomycin C (FECOM), n = 3 (1.5%); and other, n = 11 (5.4%). Forty (19.6%) patients received the best supportive care. Results: OS and PFS did not differ significantly among the DOC, S-1/DOC, FP, FECOM, and other groups (p = 0.176 and p = 0.568, respectively). The ORRs in the S-1/DOC, DOC, FP, and FECOM groups were 75.0%, 51.9 %, 38.5%, and 66.7%, respectively. The odds ratio for the ORR of the S-1/DOC group compared with the DOC group estimated by the logistic regression analysis with adjustment for age, sex, and PS was 2.72, (95% CI: 1.09-6.78, p = 0.032). S-1/DOC was the only treatment with a significantly higher ORR than that of DOC, which is the most frequently used treatment for advanced EMPD in Japan. Conclusions: Although there were no significant differences in PFS and OS between the multiple regimens, the S-1/DOC group showed significantly higher ORR compared with the DOC group. Because the high response rate to S-1/DOC greatly improves the quality of life of patients with advanced EMPD, S-1/DOC may be more beneficial than DOC and other regimens for the treatment of advanced EMPD. A phase II clinical trial of S-1/DOC is currently planned in Japan.

    Abstract: e21569 Background: Currently, lymph node dissection (LND) is not mandatory for patients with sentinel node (SN)+ melanoma. Anti-programmed cell death receptor-1 (PD-1) monotherapy and dabrafenib/trametinib combination (for BRAF mutations) are standard adjuvant treatments for patients who undergo definitive surgery for melanoma. However, the effects of this approach remain unclear in patients with stage III melanoma in real-world clinical settings. We investigated the effects of the aforementioned therapeutic approaches on the prognosis of stage III melanoma in a Japanese cohort. Methods: We retrospectively analyzed clinical data of patients with SN+ melanoma treated with or without anti-PD-1 monotherapy or combination dabrafenib/trametinib therapy obtained from 39 independent institutions in Japan between 2018 and 2021. Survival outcomes (recurrence-free survival [RFS] and overall survival [OS] ) were compared with regard to LND, adjuvant therapy type, and clinical factors. Results: We investigated 357 patients; 35.9% (128/357) of patients underwent LND, of whom 70.3% (90/128) received adjuvant therapy. LND was not performed in 64.1% (229/357) of patients, of whom 74.7% (171/229) received adjuvant therapy. RFS and OS did not differ between patients with and without LND (2-year RFS 54.5% vs. 51.5%, p = 0.98; 2-year OS 84.1% vs. 86.5%, p = 0.39). RFS and OS did not differ between patients with and without adjuvant therapy (2-year RFS 54.5% vs. 50.4%, p = 0.90; 2-year OS 83.4% vs. 89.8%, p = 0.33). Multivariate analysis of RFS after adjustment for adjuvant therapy, clinical subtype, tumor thickness, ulceration, and BRAF status showed significant differences between patients with and without adjuvant therapy (hazard ratio 3.06 [95% confidence interval 1.39–6.76]). Data analysis in 261 patients who received adjuvant therapy showed no difference between patients with and without LND (2-year RFS 55.9% vs. 52.6%, p = 0.74; 2-year OS 83.4% vs. 83.6%, p = 0.73). Regarding adjuvant therapy type, RFS and OS were significantly longer in patients who received BRAF/MEK inhibitors than in those treated with PD-1 monotherapy (2-year RFS 75.0% vs. 42.2%, p 〈 0.01; 2-year OS 89.3% vs. 79.5%, p = 0.01). Conclusions: Our study revealed that LND did not affect prognosis and adjuvant therapy reduced the recurrence of stage III melanoma in a Japanese cohort. Although the follow-up period was short, with regard to drug selection, RFS and OS were significantly longer in patients treated with BRAF/MEK inhibitors than in those who received PD-1 monotherapy. Factors contributing to the lower effectiveness of PD-1 monotherapy remain unclear and warrant further investigation.

    Abstract: 150 Background: The prognosis of patients (pts) with locally advanced esophageal squamous cell carcinoma (LAESCC) is generally dismal. Definitive chemoradiotherapy (CRT) with cisplatin plus 5-fluorouracil (CF-RT) is the standard treatments especially for the pts with unresectable LAESCC. The aim of this study is to investigate the possible prognostic factors and predictive accuracy of the Glasgow Prognostic Score (GPS) in the pts with unresectable LAESCC treated with CRT. Methods: 142 patients were enrolled to JCOG0303, and assigned to standard CF-RT group and low-dose CF-RT group. 131 pts with sufficient data were used for this analysis. Cox regression model was used for an analysis of prognostic factors of the pts with unresectable LAESCC treated with CF-RT. GPS was classified by baseline CRP and serum albumin. Pts with a CRP ≤ 1.0 mg/dL and albumin ≥ 3.5 g/dL were allocated to GPS0 group. If only CRP was increased or albumin decreased,pts were allocated to the GPS1 and pts in whom CRP was 〉 1.0 mg/dL and albumin level 〈 3.5 g/dL were classified as GPS2. Results: The pts background was as follows: median age (range), 62 (37-75), male / female, 119/12; ECOG PS 0/1/2, 64/65/2; clinical stage (UICC 6th) IIB/III/IVA/IVB, 3/75/22/31. As a result of multivariable analysis including all variables, the factors which became statistically significant were shown in the table. In several sensitivity multivariate analyses, only esophageal stenosis was indicated as a common poor prognostic factor. In addition, overall survival tended to decrease according to GPS subgroups (median survival time(m): GPS0/GPS1/GPS2 16.1/14.9/8.7). Conclusions: Presence of stenosis was thought to be one of the candidates for stratification factor in randomized trial for unresectable LAESCC pts. Furthermore, GPS represents a prognostic fator in LAESCC pts treated with CRT. Clinical trial information: 000000861. [Table: see text]

    Abstract: TPS474 Background: Supraclavicular lymph nodes (SCLN) have been regarded as regional nodes of thoracic esophageal cancer in Japan and resected along with cervical paraesophageal lymph nodes as a cervical part of the standard three-field dissection, while the involvement of SCLN is regarded as distant metastasis in Western countries. However, there is no clear evidence that supports or rejects prophylactic SCLN dissection. As postoperative SCLN metastasis can often be managed by either surgery or chemoradiotherapy at the time of relapse, routine prophylactic SCLN dissection may not be essential. Here we conduct the clinical trial to confirm the non-inferiority of esophagectomy with D2 lymphadenectomy except for SCLN to standard D2 lymphadenectomy in terms of overall survival (OS) for patients with resectable upper or middle thoracic esophageal cancer. Methods: Eligibility criteria include the followings; upper or middle thoracic esophageal squamous cell carcinoma, adenosquamous carcinoma, or basaloid cell carcinoma with clinical stage I, II, III, or IVA (except for T4) based on the 8th UICC-TNM, age 18 to 80, ECOG performance status 0 or 1, and adequate organ function. Neoadjuvant chemotherapy (cisplatin plus 5- fluorouracil or docetaxel plus cisplatin plus 5-fluorouracil) is allowed, but preoperative chemoradiotherapy is not allowed. Patients are randomly assigned to the following two arms using the minimization method with a random component to balance institution, clinical stage (Stage I (T1N0M0) versus Stage I (T1N1M0)/II/III/IVA), age (76 or older versus 75 or younger), and tumor location (upper thoracic versus middle thoracic). Patients undergo either esophagectomy with standard D2 dissection (Arm A) or esophagectomy with D2 lymphadenectomy except for SCLN (Arm B). The primary endpoint is OS in all randomized patients. The secondary endpoints are relapse-free survival, the incidence of perioperative and delayed complications, the incidence of SCLN recurrence, the incidence of salvage cervical treatment, the proportion of synchronous cervical and abdominal procedure, and operation time and the number of operating surgeons. A sample size of 456 patients would be required to observe 147 events to demonstrate the non-inferiority of Arm B in terms of OS, with a one-sided alpha of 5%, power of 70%, an accrual period of 5 years, a follow-up period of 3 years, and a non-inferiority margin of 6% at 3-year OS, assuming the expected 3-year OS of Arm A and Arm B are 80% and 81%, respectively. The planned sample size was set at 480 patients (240 patients per arm). This trial was registered at the Japan Registry of Clinical Trials (jRCT) as study number jRCT1030220248 and started in August 2022. Clinical trial information: jRCT1030220248 .

    Abstract: TPS11579 Background: Cutaneous angiosarcoma (CAS) is a rare sarcoma and advanced cases face a complex treatment regimen and dismal prognosis. Several cytotoxic agents (anthracycline, taxane, and gemcitabine) and targeted therapies (bevacizumab and sorafenib) have been tested for advanced disease in clinical trials with poor results. Since CAS commonly develops in elderly patients, high-grade adverse events from treatment may not be ideal and thus therapies featuring durable response and low comorbidity are in great demand. Recent studies suggest that CAS has a distinct genomic profile, including higher tumor mutational burden (TMB), compared to angiosarcomas developed in other sites. Moreover, we have shown that CAS with higher PD-1/L1 in the tumor microenvironment had statistically better overall survival compared with those without, indicating CAS susceptibility to immune checkpoint blockade therapy. However, to date, reports of immune checkpoint inhibitors for CAS are nonexistent. Methods: The present study is a phase 2, multicenter, single-arm clinical trial of ONO-4538 (nivolumab, 480 mg IV every 4 weeks) for patients with unresectable or metastatic CAS refractory to first-line paclitaxel. Twenty-three patients with advanced CAS will be enrolled at 11 sites in Japan with a primary objective to assess the confirmed response rate (H0 p 〈 5%, H1: p 〉 20%) to nivolumab. Secondary endpoints include PFS, OS, time to response, and adverse events. A correlative aim includes assessing tissue biomarkers using whole-genome sequencing (1023 genes including interferon-gamma associated genes and other known factors associated with response to immune checkpoint inhibitors) for association with response to nivolumab. The study started in April 2020 and remains open with 7 patients enrolled at time of Clinical trial information: UMIN000043039.

    Abstract: 9078 Background: We investigated case reports of ILD in patients receiving nivolumab for the treatment of unresectable, advanced or recurrent non-small cell lung cancer to identify risk factors for the occurrence of nivolumab-induced ILD. Methods: In Japan, post-marketing all-case surveillance of nivolumab is currently underway in patients with non-small cell lung cancer who received nivolumab from December 17, 2015 to March 31, 2016. The data were retrospectively analyzed using a multivariate stepwise logistic regression analysis with a level of significance of 5% to identify risk factors for the occurrence of nivolumab-induced ILD. Results: A total of 3,648 patients received nivolumab during the surveillance period, and data from 1,005 patients whose case report forms were available by November 30, 2016 were analyzed. Among them ILD was reported in 58 (5.8%). The median time to onset in 42 patients who were recovering or recovered from ILD was 50 days (range: 2 to 246 days). Eleven patients died of ILD. The following table summarizes univariate and multivariate analyses of risk factors for the occurrence of ILD. Conclusions: In this interim analysis of Japanese lung cancer patients treated with nivolumab, incidence of ILD as immune-related AE was 5.8%. Age, abnormal findings of chest CT, and treatment line were identified as risk factors for the occurrence of ILD during treatment with nivolumab. [Table: see text]

    Abstract: 9542 Background: Anti-PD-1 antibody monotherapy (PD1) has been commonly used for patients with advanced acral melanoma (AM). However, recent studies have demonstrated the limited clinical efficacy of PD1 in AM compared to non-acral cutaneous melanoma, particularly in nail apparatus melanoma. Although advanced AM patients are strong candidates for first-line anti-PD-1 and anti-CTLA-4 combination therapy (PD1+CTLA4), data on the clinical efficacy of PD1+CTLA4 in AM are lacking. Thus, we aimed to compare the clinical efficacies of PD1+CTLA4 and PD1 in Japanese advanced AM patients. Methods: We retrospectively reviewed the clinical records of advanced AM patients treated with PD1+CTLA4 or PD1 as first-line immunotherapy at 23 Japanese institutions. Clinical response was assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Survival was estimated using Kaplan-Meier analysis. Toxicity was assessed according to CTCAE 4.0. Results: A total of 192 patients (median age, 72 years) with advanced AM (palm and sole melanoma, 135; nail apparatus melanoma, 57) were included in the study. PD1+CTLA4 and PD1 were used as first-line immunotherapy in 39 and 153 patients, respectively. The baseline demographics and characteristics were similar between the PD1+CTLA4 and PD1 groups, except for age (median age 67.3 vs. 73.2; P = 0.005). The objective response rate (ORR) in PD1+CTLA4 was significantly higher than that of the PD1 group (38.5% vs. 16.3%; P = 0.047). The median progression-free survival (PFS) and overall survival (OS) in the PD1+CTLA4 group tended to be longer than those of the PD1 group, but the differences were not significant (median PFS 7.3 months vs. 4.5 months; P = 0.19, median OS 43.6 months vs. 18.2 months; P = 0.19). In the subgroup analysis of the palm and sole melanoma cohorts, no significant differences in ORR, PFS, and OS were observed between the PD1+CTLA4 and PD1 groups (ORR 31% vs. 20.8%; P = 0.67, median PFS 5.3 months vs. 5.9 months; P = 0.87, median OS not reached vs. 22.3 months; P = 0.66). Meanwhile, the nail apparatus melanoma cohort in the PD1+CTLA4 group exhibited significantly higher ORR, and longer PFS and OS than the PD1 group (ORR 60% vs 6.1%; P 〈 0.001; median PFS 19.6 months vs 3.8 months; P = 0.008, median OS 43.6 months vs 13.5 months; P = 0.049). Due to immune-related adverse events in all cohorts, the treatment cessation rate was higher in the PD1+CTLA4 group than the PD1 group (59% vs. 11.8%). Conclusions: PD1+CTLA4 was clinically more efficacious than PD 1 in advanced AM patients. Notably, advanced nail apparatus melanoma patients were strong candidates for first-line PD1+CTLA4.

    Abstract: 10063 Background: Controversy exists regarding the optimal surgical margin for cutaneous squamous cell carcinoma (cSCC). Current NCCN Guidelines recommend excision with a 4–6-mm clinical margin for low-risk cSCC and wider ( 〉 6-mm) clinical margin for high-risk cSCC tumors. However, adherence to this guideline is often difficult, as high-risk cSCCs frequently occur on the faces of elderly patients. Thus, we aim to investigate the correlation between different surgical margins and prognosis in patients with cSCC. Methods: Patients with cSCC who had undergone surgical excision of the primary site between 2011 and 2019 at 11 Japanese institutions were included in this study. Patients were divided into two groups: the standard margin group (SMG) with excisions adhering to the guideline-recommended margins, and narrower margin group (NMG) with excisions with narrower margins than are guideline-recommended. Local recurrence-free survival (LRFS), relapse-free survival (RFS), and overall survival (OS) were estimated using Kaplan–Meier analysis and compared between the two groups. Results: A total of 1204 patients with cSCC (SMG, 637; NMG, 567) were included in this study. RFS was significantly lower in SMG than in NMG (5-year RFS 72% vs 79%; P = 0.03); however, no statistically significant differences were observed between the two groups in LRFS (5-year LRFS 80% vs 82%; P = 0.41) or OS (5-year OS 84% vs 83%; P = 0.90). Due to striking statistical significance in several characteristics of patients between the two groups, subgroup analyses, focusing on the cohort of head and neck cSCCs, were also performed. The patient characteristics were similar between SMG and NMG in both the T1-sized tumor ( 〈 2 cm, SMG, 182; NMG, 250) and T2-sized tumor (2 cm ≤ tumor 〈 4 cm, SMG, 130; NMG, 136) cohorts, based on AJCC-TNM staging (8th edition). There were also no significant differences between the SMG and NMG in LRFS (5-year LRFS, T1: 80% vs 86%; P = 0.59; T2: 85% vs 84%; P = 0.84), RFS (5-year RFS, T1: 80% vs 81%; P = 0.84; T2: 77% vs 76%; P = 0.99), or OS (5-year OS, T1: 82% vs 87%; P = 0.42; T2: 88% vs 85%; P = 0.68). Furthermore, when the NMG was divided into the two margin groups (margins reduced by 〈 3 mm or ≥3 mm from the standard margin), no significant difference was observed in LRFS, RFS, and OS. Conclusions: This study did not reveal a significant impact of the size of clinical excision margins on survival in patients with cSCCs. Strikingly, the narrower margins may be more appropriate for 〈 4 cm-sized head and neck cSCCs.
