RESUMO
BACKGROUND: In older patients, esophageal squamous cell carcinoma (ESCC) is difficult to treat using standard therapies, including surgery and cisplatin-based chemoradiotherapy. Paclitaxel (PTX) has radiosensitizing activity. We conducted a phase I trial of PTX combined with radiotherapy to establish a standard therapy for locally advanced ESCC in older patients. METHODS: Enrollment was conducted at six centers in Japan from April 2016 to September 2019. The participants were aged ≥ 70 years, had locally advanced ESCC, and were intolerant to surgery or unwilling. A fixed 60-Gy radiation dose was administered in 30 fractions. PTX dosing levels started at 30 mg/m2 weekly for 6 weeks. Depending on the number of DLTs, the dose was set to be increased by 10 mg/m2 or switched to biweekly. A geriatric assessment was performed before treatment using the Geriatric-8 screening tool. The primary endpoint was dose-limiting toxicity (DLT). RESULTS: We enrolled 24 patients (6 per group); DLT was observed in one (grade 4 hypokalemia), one (grade 3 aspiration), two (grade 3 radiodermatitis, grade 3 esophageal hemorrhage), and two (grade 3 anorexia, grade 5 pneumonitis) patients in the weekly PTX 30, 40, 50, and 60 mg/m2 groups, respectively. All adverse events, except death in the 60 mg/m2 group, showed reversible improvement, and the safety profile was considered acceptable. The 2-year survival and complete response rates were 40.0% and 54.2%, respectively. There was a significant difference in survival between favorable and unfavorable Geriatric-8 scores. CONCLUSIONS: The recommended PTX dose with concomitant radiation was determined to be 50 mg/m2 weekly. Phase II trials at this dose are underway.

Although phase III randomized controlled trials (RCTs) represent the most robust statistical approach for answering clinical questions, they require massive expenditures in terms of time, labor, and funding. Ancillary and supplementary analyses using RCTs are sometimes conducted as alternative approaches to answering clinical questions, but the available integrated databases of RCTs are limited. In this background, the Colorectal Cancer Study Group (CCSG) of the Japan Clinical Oncology Group (JCOG) established a database of ancillary studies integrating four phase III RCTs (JCOG0212, JCOG0404, JCOG0910 and JCOG1006) conducted by the CCSG to investigate specific clinicopathological factors in pStage II/III colorectal cancer (JCOG2310A). This database will be updated by adding another clinical trial data and accelerating several analyses that are clinically relevant in the management of localized colorectal cancer. This study describes the details of this database and planned and ongoing analyses as an initiative of JCOG cOlorectal Young investigators (JOY).

BACKGROUND: The phase 3 BEACON CRC study demonstrated the survival benefits of encorafenib and cetuximab, with or without binimetinib (the BEACON triplet or doublet regimen), for BRAFV600E-mutant metastatic colorectal cancer (mCRC). This expanded access program (EAP) and subsequent follow-up study assessed the efficacy and safety of the BEACON triplet regimen in Japanese patients with BRAFV600E-mutant mCRC. MATERIALS AND METHODS: The EAP was an open-label, single-arm study including Japanese patients with BRAFV600E-mutant mCRC whose disease progressed after 1 to 2 prior regimens. The patients received the BEACON triplet regimen with 28-day cycles. The subsequent follow-up study assessed the survival outcomes following EAP completion. Safety was assessed only during the EAP. RESULTS: Among the 86 enrolled patients, 81 received the BEACON triplet regimen. The objective response rate and median progression-free survival were 27.6% (95% confidence interval [CI], 18.0%-39.1%) and 5.26 (95% CI, 4.14-5.52) months, respectively. Grade 3 to 4 adverse events and treatment-related adverse events occurred in 43.2% and 28.4% of patients, respectively. No new safety signals were observed during the EAP. Among 58 patients with confirmed survival at EAP completion, 57 were included in the follow-up study. With a median observation period of 9.17 months through the EAP and follow-up study, the median overall survival was 10.38 (95% CI, 9.00-16.16) months. CONCLUSION: The efficacy and safety of the BEACON triplet regimen in Japanese patients with BRAFV600E-mutant mCRC were consistent with those reported in the BEACON CRC trial, supporting its use as a standard treatment for pretreated patients with BRAFV600E-mutant mCRC.

BACKGROUND: Radical gastrectomy followed by adjuvant chemotherapy is the standard treatment for stage II or III gastric cancer in Asian countries. Early recurrence during or after adjuvant chemotherapy is associated with poor prognosis; however, risk factors for early recurrence remain unclear. METHODS: In this multicenter, retrospective cohort study including six institutions, we evaluated the clinicopathological factors of 553 patients with gastric cancer undergoing gastrectomy followed by adjuvant chemotherapy between 2012 and 2016. Patients were divided into the following groups: early recurrence (recurrence during adjuvant chemotherapy or within 6 months after adjuvant chemotherapy completion) and non-early recurrence, which was further divided into late recurrence and no recurrence. Early-recurrence risk factors were investigated using multivariate Cox proportional hazard model. The chronological changes in the recurrence hazard were also examined for each factor. RESULTS: Early recurrence and late recurrence occurred in 83 (15.0%) and 73 (13.2%) patients, respectively. Based on the Cox proportional hazards model, a postoperative serum carcinoembryonic antigen level of ≥5 ng/mL (hazard ratio: 2.220, 95% confidence interval: 1.089-4.526) and a neutrophil-to-lymphocyte ratio of >1.8 (hazard ratio: 2.408, 95% confidence interval: 1.479-3.92) were identified as independent risk factors of early recurrence, but not late recurrence. The recurrence hazard ratios for neutrophil-to-lymphocyte ratio significantly decreased over time (P < 0.001) and carcinoembryonic antigen also had the same tendency (P = 0.08). CONCLUSIONS: A carcinoembryonic antigen level of ≥5 ng/mL and a neutrophil-to-lymphocyte ratio of >1.8 are predictors of early recurrence after radical gastrectomy and adjuvant chemotherapy for stage II or III gastric cancer.

BACKGROUND: The development of triplet regimens for advanced gastric cancer is challenging. The aim of this phase I dose-escalation study was to determine the maximum tolerated dose and recommended dose of the combination of irinotecan, cisplatin, and S-1 in chemotherapy-naïve patients with HER2-negative advanced gastric cancer. METHODS: The 3 + 3 design was adopted. Every 4 weeks, patients received an escalating dose of intravenous irinotecan (100-150 mg/m2) on day 1 and fixed doses of intravenous cisplatin (60 mg/m2) on day 1 and oral S-1 (80 mg/m2) on days 1 to 14. RESULTS: Twelve patients were enrolled in two dose level cohorts. In the level 1 cohort (irinotecan 100 mg/m2, cisplatin 60 mg/m2, and S-1 80 mg/m2), dose-limiting toxicity including grade 4 neutropenia and febrile neutropenia occurred in one of six patients, whereas in the level 2 cohort (irinotecan 125 mg/m2, cisplatin 60 mg/m2, and S-1 80 mg/m2), dose-limiting toxicities including grade 4 neutropenia developed in two of six patients. Thus, the level 1 and 2 doses were determined to be the recommended and maximum tolerated doses, respectively. Common grade 3 or higher adverse events were neutropenia (75%; n = 9), anemia (25%; n = 3), anorexia (8%; n = 1), and febrile neutropenia (17%; n = 2). Irinotecan, cisplatin, and S-1 combination therapy achieved an overall response rate of 67% with a median progression-free survival and overall survival of 19.3 and 22.4 months, respectively. CONCLUSIONS: The potential treatment efficacy of this triplet regimen in HER2-negative advanced gastric cancer warrants further evaluation, especially in patients requiring intensive chemotherapy.

BACKGROUND: Surgical resection of oligo-metastasis in gastric cancer (GC) is weakly recommended for patients without other incurable factors in the Japanese GC Treatment Guidelines. While post-operative chemotherapy is the standard treatment in patients with stage II or III GC, its efficacy for resected stage IV GC is unclear. This study aimed to evaluate the efficacy of post-operative chemotherapy after curative resection of GC with oligo-metastasis. METHODS: We retrospectively reviewed the medical records of patients with GC who were diagnosed with synchronous oligo-metastasis at 20 institutions in Japan between 2007 and 2012. The selection criteria were: adenocarcinoma, stage IV with oligo-metastasis at liver or lymph node without other distant metastasis, curative resection including synchronous oligo-metastasis, and no prior treatment of GC before surgery. RESULTS: A total of 110 patients were collected. Of the 94 eligible patients, 84 underwent gastrectomy with surgical resection of oligo-metastasis (39 [41%] liver metastasis and 55, [59%] distant lymph node metastasis), followed by post-operative chemotherapy with S-1 (S1: n = 55), S1 plus cisplatin (CS: n = 22), or Others (n = 7). Moreover, 10 patients did not receive post-operative chemotherapy (Non-Cx). The median overall survival (OS) was 35.2 and 11.1 months in the post-operative chemotherapy and Non-Cx groups (hazard ratio, 3.56; 95% confidence interval, 1.74-7.30; p < 0.001), respectively. In multivariable analysis, Non-Cx and age over 70 years were identified as poor prognostic factors for OS (p < 0.05). CONCLUSIONS: Curative resection followed by post-operative chemotherapy in patients with GC with synchronous oligo-metastasis showed favorable survival.

BACKGROUND: Accelerated tumor growth during immunotherapy in pre-existing measurable lesions, hyperprogressive disease (HPD), has been reported. However, progression of non-measurable lesions and new lesions are frequently observed in patients with advanced gastric cancer (AGC). METHODS: This retrospective study involved AGC patients at 24 Japanese institutions who had measurable lesions and received nivolumab after ≥ 2 lines of chemotherapy. HPD was defined as a ≥ two-fold increase in the tumor growth rate of measurable lesions. The pattern of disease progression was classified according to new lesions in different organs and ascites appeared/increase of ascites. RESULTS: Of 245 patients, 147 (60.0%) showed progressive disease (PD) as the best response and 41 (16.7%) showed HPD during nivolumab monotherapy. There was no significant difference in overall survival (OS) between patients with HPD and those with PD other than HPD (median OS 5.0 vs 4.8 months; hazard ratio [HR] 1.0, 95% confidence interval [CI] 0.6-1.5; p = 1.0). Fifty-three patients developed new lesions in different organs and 58 had appearance/increase of ascites; these patients showed shorter OS than those without each of these features (median OS 3.3 vs 7.1 months, HR 1.8, 95% CI 1.2-2.7, p = 0.0031 for new lesions, and 3.0 vs 7.8 months, HR 2.6, 95% CI 1.8-3.8, p < 0.0001 for ascites). Thirty-one patients who had both features showed the worst prognosis (median OS 2.6 months). CONCLUSIONS: New lesions in different organs and appearance/increase of ascites, rather than the original definition of HPD, are the patterns of disease progression associated with poor prognosis in AGC patients receiving nivolumab whose best response was PD.

The BRAF V600E mutation accounts for approximately 5% of colorectal cancer (CRC) cases and is an extremely poor prognostic factor. However, there are no clear recommendations regarding first-line therapy for patients with early recurrent BRAF V600E-mutated CRC, during or after adjuvant chemotherapy. Recently, a novel combination of encorafenib, binimetinib and cetuximab, showed a higher response rate than standard chemotherapy in patients with BRAF V600E-mutated CRC. Here we describe our plan for the TRESBIEN study (OGSG 2101), which is an open-label, multicenter, single-arm, phase II study designed to evaluate whether encorafenib, binimetinib and cetuximab are effective for patients with early recurrent BRAF V600E-mutated colorectal cancer, during or after adjuvant chemotherapy. The planned number of subjects is 25.
An ongoing study to evaluate encorafenib, binimetinib and cetuximab for people with early recurrent BRAF V600E-mutated colorectal cancer. BRAF V600E-mutated colorectal cancer (CRC) is a type of cancer caused by change (mutation) in a gene called BRAF. It is one of the most difficult types of CRC to treat because currently available drugs do not effectively treat the disease. Recently, two novel treatments, encorafenib and cetuximab, have been approved for use together in several countries for the treatment of advanced or metastatic BRAF V600E-mutated CRC. In Japan, these drugs are also approved to be given with another treatment called binimetinib, an approach called triplet therapy. This article describes the ongoing TRESBIEN study that is looking at how effective and how safe triplet therapy is for the treatment of people with early recurrent BRAF V600E-mutated CRC, during or after they have additional (adjuvant) chemotherapy. This study is ongoing, and the researchers are currently recruiting new participants. TRESBIEN will evaluate the percentage of participants whose tumors shrink with triplet therapy. The study will also look at any side effects. Clinical Trial Registration: jRCTs051210152 (ClinicalTrials.gov) (Japan Registry of Clinical Trials https://jrct.niph.go.jp/search?language=en&page=1).

Aims: In this study, we focused on the fat ratio within psoas muscle (FRPM) and sought to clarify the impact of FRPM on overall survival (OS) in stage IV gastric cancer (GC) patients undergoing systemic chemotherapy (n = 79, median age = 69 years, 59 males). Methods: The median FRPM was 1.67 %. Forty patients with FRPM ≥1.67 % were defined as the FRPM-high group, and the remaining 39 patients was defined as the FRPM-low group. The median PMI in male and female patients was 4.35 cm2/m2 and 2.88 cm2/m2. Thirty male patients with PMI ≥4.35 cm2/m2 and 10 female patients with PMI ≥2.88 cm2/m2 was defined as the PMI-high group, and the remaining 39 patients was defined as the PMI-low group. Results: The 1-, 2- and 3- year cumulative OS rate for all cases was 70.8%, 24.3% and 14.6%. The proportion of ECOG-PS 2 or 3 in patients with FRPM-high and FRPM-low was 17.5% (7/40) and 2.6% (1/39). The 1-, 2- and 3- year cumulative OS rate in patients with FRPM-high and FRPM-low was 67.3%, 14.3% and 7.6% in the FRPM-high group and 74.8%, 40.5% and 32.4% in the FRPM-low group (P = 0.0341). The 1-, 2- and 3- year cumulative OS rate in patients with PMI-high and PMI-low was 86.7%, 40.4% and 30.0% in the PMI-high group and 55.8%, 12.8% and 6.4% in the PMI-low group (P < 0.0001). In the multivariate analysis of factors associated with OS, PMI (P = 0.0047) and FRPM (P = 0.0019) were independent predictors for the OS. Conclusion: Higher FRPM can be associated with decreased physical activity, and not only skeletal muscle mass but also skeletal muscle function can be an essential prognostic factor in stage IV GC patients undergoing systemic chemotherapy.
RESUMO
BACKGROUND/AIM: To prospectively evaluate the efficacy and safety of the BNT162b2 vaccine in solid cancer patients undergoing systemic chemotherapy (n=63). PATIENTS AND METHODS: COVID-19 anti-spike protein antibody levels were measured before the first BNT162b2 vaccination, just before the second BNT162b2 vaccination, one month after the second BNT162b2 vaccination, and 3 months after the second BNT162b2 vaccination. Anti-spike protein antibody seropositivity was set at ≥0.8 U/ml. RESULTS: Colorectal cancer was the most commonly observed primary disease (36.5%). ECOG-PS 0 was observed in the majority (52.4%) of patients. The overall response rate and the median (range) anti-spike protein antibody levels in the whole cohort at 3 months after the second BNT162b2 vaccination were 98.4% (62/63) and 206 (0.4-3,813) U/ml. None of the patients required postponement or discontinuation of systemic chemotherapy because of an adverse reaction. CONCLUSION: The BNT162b vaccine in solid cancer patients undergoing systemic chemotherapy is effective and safe.

BACKGROUND: Although docetaxel plus S-1 adjuvant chemotherapy after gastrectomy with D2 lymphadenectomy has been a standard of treatment for stage III gastric cancer, there is no established chemotherapy for patients with recurrence during or within six months after the completion of adjuvant docetaxel plus S-1 therapy. METHODS: The OGSG 1901 trial is a prospective, open-label, multicenter, phase II trial evaluating ramucirumab plus irinotecan for gastric cancer patients with early relapse after adjuvant docetaxel plus S-1 therapy. The key eligibility criteria were: 1) histologically confirmed gastric adenocarcinoma 2) patients who were on docetaxel plus S-1 adjuvant chemotherapy after the confirmation of pathological stage III, 3) patients with early relapse, i.e., recurrence during or within 6 months after the completion of docetaxel plus S-1 therapy, and 4) patient with Eastern Cooperative Oncology Group performance status of 0-1. Irinotecan (150 mg/m2, day 1) and ramucirumab (8 mg/kg, day 1) will be administered every 2 weeks. The primary endpoint is overall survival, and the secondary endpoints are overall response rate, progression-free survival, and safety. The number of patients has been set at 40 based on the threshold and expected median survival times of 7 and 11 months, respectively, with a one-sided alpha error of 0.05 and power of 0.80. The enrollment and follow-up periods are 2 and 1.5 years, respectively. DISCUSSION: The results of this trial will indicate whether the ramucirumab with irinotecan regimen has the potential to be a recommended treatment regimen for patients with recurrence gastric cancer during or within 6 months after the completion of adjuvant docetaxel plus S-1 therapy. TRIAL REGISTRATION: This study was registered in the Japan Registry of Clinical Trials ( jRCTs05119071 , October 6, 2019).

Introduction: Previous prospective studies suggest that the sequential use of cytotoxic agents, such as oxaliplatin, in patients with metastatic colorectal cancer (mCRC) has the potential to improve prognosis and maintain quality of life than combination chemotherapy. The purpose of this study was to investigate the feasibility and effectiveness of a sequential treatment strategy consisting of an initial therapy (capecitabine, S-1, or 5-fluorouracil with leucovorin [LV/5-FU] plus bevacizumab) and subsequent therapy (i.e., initial therapy plus oxaliplatin) for mCRC. Methods: The primary endpoint was second progression-free survival (2nd PFS) between the start of initial therapy and tumor progression after sequential therapy; secondary endpoints were PFS after initial treatment, overall survival (OS), objective response rate (ORR), and safety. Results: Sixty-six patients were planned to be recruited. However, owing to a slow accrual rate, recruitment was terminated when only 19 patients were enrolled between 2011 and 2015; 4, 10, and 5 patients were administered capecitabine plus bevacizumab, S-1 plus bevacizumab, and LV/5-FU plus bevacizumab, respectively. The proportions of those with a KRAS status (wild-type/mutant/unknown) were 26%, 21%, and 53%, respectively. The median 2nd PFS and OS were 19.1 months and not reached, respectively. The ORR was 45.5% in the initial therapy and 16.7% in the subsequent therapy. Grade 3/4 toxicities included neutropenia (5%), proteinuria (5%), and hypertension (47%). Conclusion: Although our data are limited and preliminary, the sequential treatment strategy may provide a survival benefit in patients with mCRC. Further investigation of this treatment approach is warranted.
RESUMO
BACKGROUND/AIM: Neoadjuvant chemotherapy without radiation (NAC) shows favorable outcomes for locally advanced rectal cancer (LARC), however, the optimal regimen has not been determined yet. This study aimed to compare the efficacy and safety of oxaliplatin, irinotecan, folinic acid, and 5-fluorouracil (mFOLFOXIRI) with capecitabine/S-1 and oxaliplatin (XELOX/SOX) in rectal cancer patients. PATIENTS AND METHODS: We retrospectively examined patients with LARC who received mFOLFOXIRI or XELOX/SOX as NAC. RESULTS: Between January 2015 and July 2019, 49 patients received mFOLFOXIRI and 37 patients received XELOX/SOX. The pathological response rates (over two-thirds affected tumor area) were 36.7% and 40.5% in the mFOLFOXIRI and XELOX/SOX groups, respectively. Grade 3/4 neutropenia was experienced by 45.0% of the patients in the mFOLFOXIRI group and 8.0% in the XEOX/SOX group. CONCLUSION: Although pathological responses were comparable between two groups, mFOLFOXIRI tended to be more toxic compared to XELOX/SOX as NAC for LARC.

BACKGROUND: Regorafenib is a key agent for patients with advanced or recurrent colorectal cancer. Sarcopenia represented by skeletal muscle depletion is closely related to frailty and predicts oncological prognoses. We hypothesized that sarcopenia negatively affects the time to treatment failure (TTF) or overall survival (OS) of patients treated with regorafenib. METHODS: We retrospectively reviewed the medical records of all patients treated with regorafenib between May 2013 and April 2019 at our institution. The cross-sectional area of the psoas muscle at the level of the third lumbar vertebra on baseline computed tomography (CT) was assessed to calculate the psoas muscle index (PMI). Sarcopenia was defined based on PMI cut-off values for Asian adults (6.36 cm2/m2 for males and 3.92 cm2/m2 for females). RESULTS: Thirty-four patients were analyzed. The prevalence of sarcopenia was 44.1%. Sarcopenia was significantly associated with poorer OS (median 3.2 vs. 5.3 months, p = 0.031). Less 75% 1-Month Relative Dose Intensity patients experienced significantly shorter TTF and OS than the rest, as did patients receiving total regorafenib dose of < 3360 mg (median 3.1 and 9.4 months, p < 0.001). Multivariate analysis showed that sarcopenia was a significant predictor of prognosis. CONCLUSION: Sarcopenia was a predictive marker of negative outcome for patients with advanced or recurrent colorectal cancer treated with regorafenib. Screening for sarcopenia can be used to identify patients more likely to benefit from regorafenib in routine clinical practice.

BACKGROUND: Hepatectomy has a high risk of perioperative bleeding due to the underlying disease. Here, we investigated the postoperative impact of allogeneic blood transfusion during hepatectomy. METHODS: The surgical outcomes in 385 patients who underwent hepatic resection for hepatocellular carcinoma were retrospectively reviewed. The association of allogeneic blood transfusion with surgical outcomes and remnant liver regeneration data was analyzed. RESULTS: Eighty-six patients (24.0%) received an allogeneic blood transfusion and 272 patients (76.0%) did not. After propensity score matching, the incidence rates of postoperative complication (Clavien-Dindo grade >IIIA), posthepatectomy liver failure, and massive ascites were significantly higher for the group that received a blood transfusion than for the group that did not receive blood transfusion (P < .001, P = .001, and <.001, respectively). Postoperative measures of total bilirubin, albumin, platelet count, prothrombin time, aspartate aminotransferase, and alanine aminotransferase were significantly more favorable in patients without blood transfusion until day 7 after surgery. There were no correlations in the remnant liver regeneration at 7 days, and 1, 2, 5, and 12 months postoperatively between the 2 groups (P = .585, .383, .507, .261, and .430, respectively). Regarding prognosis, there was no significant difference in overall and recurrence-free survival between the 2 groups (P = .065 and .166, respectively). CONCLUSION: Allogeneic transfusion during hepatectomy strongly affected remnant liver function in the early postoperative period; however, this was not related to the remnant liver regeneration volume. Despite that the allogeneic transfusion resulted in poorer postoperative laboratory test results and increased postoperative complication and mortality rates, it had no effect on the long-term prognosis.

BACKGROUND: Gastric cancer (GC) patients with peritoneal metastasis are defined as stage IV in the Japanese classification of GC. For patients with peritoneal metastasis limited to positive peritoneal lavage cytology (CY1) and/or localized peritoneal metastasis (P1a), gastrectomy followed by S1 monotherapy is one of the most widely accepted therapeutic strategy in Japan. This study investigated the efficacy of preoperative chemotherapy as initial treatment in GC patients with CY1 and/or P1a. METHODS: We retrospectively reviewed GC patients diagnosed with CY1 and/or P1a at 34 institutions in Japan between 2008 and 2012. Selection criteria were: adenocarcinoma, no distant metastasis except CY1 or P1a, and no prior treatment. The subjects were divided into an Initial-Chemotherapy group and an Initial-Surgery group, according to the initial treatment. RESULTS: A total of 824 patients were collected and 713 eligible patients were identified for this study. As the initial treatment, 150 patients received chemotherapy (Initial-Cx), and 563 patients underwent surgery (Initial-Sx). Initial-Cx regimens were cisplatin plus S1/docetaxel plus cisplatin plus S1/others (n = 90/37/23). Both overall survival (OS) and progression-free survival (PFS) were similar between the Initial-Cx and Initial-Sx groups (median OS 24.8 and 24.0 months, HR 1.07, 95% CI 0.87-1.3; median PFS 14.9 and 13.9 months, HR 1.04, 95% CI 0.85-1.27). The 5-year OS rates were 22.3% in the Initial-Cx group and 21.5% in the Initial-Sx group. CONCLUSIONS: Although, the preoperative chemotherapy did not show a survival benefit for GC patients with CY1 and/or P1a, initial-Cx showed favorable survival in patients who converted to P0 and CY0.

BACKGROUND/AIM: To prevent infusion-related reactions (IRRs), H1-antihistamines (H1AT) are recommended as a premedication for monoclonal antibodies, such as Ramucirumab (RAM), even though there are H1AT-related side effects, such as drowsiness and dizziness. Here, we investigated the safety of H1AT-free RAM regimens in patients with solid cancer. PATIENTS AND METHODS: We retrospectively reviewed the patients with solid cancer receiving RAM without H1AT at Osaka Medical College Hospital between 2015 and 2019. RESULTS: Among the 123 registered patients, 58 were identified as eligible. The total number of RAM infusions was 291, and the median number of RAM administration was 4 cycles (range=1-23 cycles). IRRs were not observed in any patient. CONCLUSION: Although our data are preliminary and limited, H1AT-free RAM regimens may be a treatment option for cancer patients having a significant risk of developing H1AT-related side effects. Further studies are needed to confirm the safety of H1AT-free RAM regimens.

A 59-year-old woman had a history of distal gastrectomy and D2 dissection in May 200X for advanced gastric cancer(GC) in the antrum area. The pathological stage was poorly differentiated, T2(SS), N2, H0, P0, CY0, M0, pStage â ¢A. After administration of S-1 for 1 year as adjuvant chemotherapy, the patient underwent surveillance with no recurrence. However, remnant GC was diagnosed in April 200X+12. Considering that there was no indication for curative resection due to severe invasion of the proper hepatic artery, gastrojejunostomy was performed for the anastomotic stenosis. Although the patient was administered 3 courses of S-1 plus oxaliplatin therapy as first-line treatment, partial response was not achieved. Therefore, chemoradiotherapy(CRT)with capecitabine was administered for local tumor control. Complete response was achieved, and the patient underwent surveillance with no recurrence 16 months after the recurrence. There were no serious acute adverse events(AEs)during CRT and late AEs after CRT. The patient was successfully treated with CRT for locally advanced remnant GC. Although there is no standard treatment for locally advanced remnant GC, this case showed the effectiveness of CRT.
