Stomatitis, which is a common side effect of chemotherapy, currently lacks a standardized approach for its prevention. Therefore, this multicenter, randomized, open-label, controlled phase III trial aims to assess the efficacy and safety of a dexamethasone-based mouthwash for preventing chemotherapy-induced stomatitis in patients with early breast cancer. We will randomly assign 230 patients with early breast cancer scheduled to receive chemotherapy in a 1:1 ratio to either the dexamethasone-based mouthwash group (10 ml, 0.1 mg/ml; swish for 2 min and spit 4 times daily for 8 weeks) or the mouthwash-with-tap-water group. The incidence of stomatitis, measured using electronic patient-reported outcomes, is the primary endpoint.

Objective: To evaluate the additive effect of naldemedine tosylate (naldemedine) on opioid-induced constipation in cancer patients insufficiently responding to magnesium oxide treatment.
Methods: We combined two randomized, double-blind, placebo-controlled, phase IIb and III trials of naldemedine and conducted a post hoc subgroup analysis. We evaluated the effect and safety of naldemedine in 116 patients who received naldemedine in addition to magnesium oxide (naldemedine group) and 117 patients who received placebo in addition to magnesium oxide (placebo group). Both groups included patients insufficiently responding to magnesium oxide for opioid-induced constipation. Effect was assessed using spontaneous bowel movement responder rate, complete spontaneous bowel movement responder rate, changes in spontaneous bowel movements and complete spontaneous bowel movements. Safety was also assessed.
Results: During the 2-week treatment period, the responder rates for spontaneous bowel movement and complete spontaneous bowel movement were 73.3 and 43.1% in naldemedine group, respectively, which were significantly higher (P < 0.0001) than 41.9 and 14.5% in placebo group, respectively. Median time to first spontaneous bowel movement and first complete spontaneous bowel movement was significantly shorter (P < 0.0001) in the naldemedine group (4.0 and 21.3 h, respectively) than in the placebo group (27.7 and 211.7 h, respectively). The incidence of adverse events and diarrhoea was significantly higher (P < 0.05) in the naldemedine group than in the placebo group, while the incidence of serious adverse events and severe diarrhoea was not significantly different between the naldemedine and placebo groups.
Conclusion: The study suggested the addition of naldemedine as an effective treatment option for opioid-induced constipation in cancer patients insufficiently responding to magnesium oxide treatment.

Background: There is an increased risk of acute exacerbation of idiopathic interstitial pneumonia when treating patients with advanced non-small cell lung cancer with idiopathic interstitial pneumonia. There is no standard optimal treatment regimen for patients with lung cancer complicated with idiopathic interstitial pneumonia. We aimed to evaluate the efficacy and safety of carboplatin (CBDCA), bevacizumab (Bmab) and weekly paclitaxel (PXT) in patients with idiopathic interstitial pneumonia.
Methods: This phase 2 study involved chemotherapy-naïve patients with advanced non-small cell lung cancer with idiopathic interstitial pneumonia. Patients received CBDCA (area under the curve: 5 on day 1), PXT (70 mg/m2 on days 1, 8 and 15) and Bmab (15 mg/kg on day 1) every 4 weeks. The primary endpoint was the overall response rate.
Results: Twenty-one patients were enrolled between January 2013 and October 2018 and received at least one course of the protocol treatment. The study was terminated before enrolling the planned number of patients because of poor accrual. The median patient age was 69 (range: 62-79) years, and 19 (90.5%) patients were men. The overall response rate was 61.9% (95% confidence interval [CI], 38.4-81.9), meeting the primary endpoint. The median progression-free survival, time to treatment failure, and overall survival were 9.69 (95% CI, 5.78-11.63), 8.21 (95% CI, 3.75-11.63) and 20.93 (95% CI, 13.17-29.83) months, respectively. There was no acute exacerbation or treatment-related death during protocol treatment.
Conclusion: The results indicate that patients with advanced non-squamous, non-small cell lung cancer with idiopathic interstitial pneumonia could be effectively and safely treated using a combination of CBDCA, PXT and Bmab.

Objective: This study evaluated the short-and long-term outcomes of laparoscopic colectomy versus open surgery in obese patients (body mass index ≥25 kg/m2) with locally advanced colon cancer to ascertain the non-inferiority of laparoscopic surgery to open surgery.
Methods: In this large cohort study (UMIN-ID: UMIN000033529), we retrospectively reviewed prospectively collected data from consecutive patients who underwent laparoscopic or open surgery for pathological stage II-III colon cancer between 2009 and 2013. A comparative analysis was performed after propensity score matching between the laparoscopic and open surgery groups. The primary endpoint was the 3-year relapse-free survival (RFS).
Results: We identified 1575 eligible patients from 46 institutions. Each group comprised 526 propensity score-matched patients. Comparing the laparoscopic versus open surgery group, laparoscopic surgery was significantly associated with increased median operating time (225 vs. 192.5 min; P < .0001) and decreased median estimated blood loss (20 vs. 140 ml; P < .0001). Lymph node retrieval (20 vs. 19; P = 0.4392) and postoperative complications (4.6% vs. 5.7%; P = 0.4851) were similar, postoperative hospital stay was shorter (10 vs. 12 days; P < .0001), and the 3-year RFS rates were similar (82.8 vs. 81.2%). The hazard ratio (HR) for relapse-free survival for laparoscopic versus open surgery was 0.927 (90% confidence interval [CI], 0.747-1.150, one-sided P for non-inferiority = .001), indicating that for obese patients with colon cancer, laparoscopic surgery was non-inferior to open surgery.
Conclusion: Laparoscopic surgery in obese patients with colon cancer offers advantages in terms of short-term outcomes and no disadvantages in terms of long-term outcomes.

Objective: This research aimed to establish the inaugural evidence-based cancer survivorship guidelines for Japan, with a particular focus on exercise and physical activity, in order to enhance health outcomes for cancer survivors.
Methods: A panel of experts, including oncologists, physicians, exercise scientists, epidemiologists and patient advocates, utilized a modified Delphi process and systematic reviews to establish consensus on exercise recommendations for cancer survivors. The panel focused on setting the objectives of the Clinical Practice Guidelines and addressing crucial clinical issues in Japan. Recommendations were formulated based on the strength and certainty of evidence, the benefit-harm balance and patient values and preferences.
Results: The panel formulated exercise recommendations for cancer survivors of two age groups: 18-64 years and ≥65 years. The recommendations for both age groups are consistent, emphasizing the importance of regular exercise and physical activity tailored to individual capabilities and health conditions. The guidelines underline the benefits of exercise in improving the overall health and quality of life of cancer survivors. This consensus on exercise recommendations marks a significant step in the development of comprehensive cancer survivorship guidelines in Japan, with potential implications for improving clinical outcomes and advancing research in cancer survivorship.
Conclusions: These guidelines will serve as a critical resource for cancer survivors, highlighting exercise as a key component of survivorship care, and for clinicians, in recommending appropriate physical activities to improve survivor health and well-being.

Background: In recent years, as the availability of precision therapies expands, there is increasing reliance on genomic profiling assays to help identify the most appropriate treatment options for patients with advanced cancers. We retrospectively investigated the results of comprehensive genomic profiling tests from the time insurance coverage began until recently and examined the status of genetic analysis.
Methods: We retrospectively reviewed the analysis results of 300 patients with advanced solid tumors who consented to comprehensive genomic profiling tests from October 2019 to December 2022.
Results: Of the 300 patients who underwent comprehensive genomic profiling tests, analysis results for 274 patients were obtained, and were reviewed by the Clinical Genome Expert Panel. Six specimens (2%) were discontinued due to patient deaths and deteriorations in general condition. The three most frequently occurring actionable genomic alterations observed were TP53 (47.4%), KRAS (28.1%) and CDKN2A (20.4%). The most common druggable variant was CDKN2A, which was noted in 52 (19%) of 274 patients. The next most common were PIK3CA, BRAF, KRAS and PTEN. The cancer types that showed a greater median number of actionable alterations comprised thyroid cancer, pancreatic cancer and colorectal cancer.
Conclusions: In conclusion, comprehensive genomic profiling tests have the potential to be valuable in identifying genomic abnormalities. Even if there is no effective treatment at present, it may lead to a treatment in the future. Comprehensive genomic profiling tests should be considered for any cancer.

The goal of surgery for patients with newly diagnosed glioblastoma (GBM) is maximum safe resection of the contrast-enhancing (CE) lesion on magnetic resonance imaging. However, there is no consensus on the efficacy of FLAIRectomy, which is defined as the possible resection of fluid-attenuated inversion recovery (FLAIR)-hyperintense lesions surrounding the CE lesion. Although retrospective analyses suggested the potential benefits of FLAIRectomy, such outcomes have not been confirmed by prospective studies. Therefore, we planned a multicenter, open-label, randomized controlled phase III trial to evaluate the efficacy of FLAIRectomy compared with gross total resection of CE lesions in patients with newly diagnosed GBM. The primary endpoint is overall survival. In total, 130 patients will be enrolled from 47 institutions over 5 years. This trial has been registered at the Japan Registry of Clinical Trials (study number jRCT1031230245).
对新诊断的胶质母细胞瘤(GBM)患者进行手术的目的是最大限度地安全切除磁共振成像中的对比度增强(CE)病灶。然而,FLAIR切除术的疗效尚未达成共识,FLAIR切除术的定义是可能切除CE病灶周围的流体增强反转恢复(FLAIR)高密度病灶。虽然回顾性分析表明了FLAIR切除术的潜在益处,但前瞻性研究尚未证实这种结果。因此,我们计划进行一项多中心、开放标签、随机对照的 III 期试验,以评估在新诊断的 GBM 患者中,FLAIR 切除术与 CE 病灶全切术相比的疗效。主要终点是总生存期。共有来自 47 家机构的 130 名患者将在 5 年内入组。该试验已在日本临床试验注册中心注册(研究编号为 jRCT1031230245)。

During the COVID-19 pandemic period, many patients who required outpatient chemotherapy developed COVID-19, requiring chemotherapy interruption. However, there are no clear guidelines regarding the safe timing for restarting chemotherapy. We conducted a retrospective study to assess when such patients can safely recommence chemotherapy. Of the 40 patients included in this study, 34 restarted anticancer drug therapy after COVID-19 infection. Six patients, four with multiple myeloma, and one each with follicular lymphoma and glioma, remained SARS-CoV-2 antigen positive >20 days after COVID-19 onset. Multiple myeloma patients recorded significantly higher frequencies of SARS-CoV-2 antigen positivity >20 days after COVID-19 onset compared with solid tumor patients, with no significant differences in the frequency of SARS-CoV-2 positivity during 5-20 days from COVID-19 onset between them. According to our data, most solid tumor patients achieved SARS-CoV-2 antigen negativity after 20 days from COVID-19 onset. On the other hand, multiple myeloma patients might need serial antigen tests before restarting anticancer therapy in the outpatient chemotherapy setting.

However, there are no clear guidelines regarding the safe timing for restarting chemotherapy. We conducted a retrospective study to assess when such patients can safely recommence chemotherapy. Of the 40 patients included in this study, 34 restarted anticancer drug therapy after COVID-19 infection. Six patients, four with multiple myeloma, and one each with follicular lymphoma and glioma, remained SARS-CoV-2 antigen positive >20 days after COVID-19 onset. Multiple myeloma patients recorded significantly higher frequencies of SARS-CoV-2 antigen positivity >20 days after COVID-19 onset compared with solid tumor patients, with no significant differences in the frequency of SARS-CoV-2 positivity during 5-20 days from COVID-19 onset between them. According to our data, most solid tumor patients achieved SARS-CoV-2 antigen negativity after 20 days from COVID-19 onset. On the other hand, multiple myeloma patients might need serial antigen tests before restarting anticancer therapy in the outpatient chemotherapy setting.","PeriodicalId":14656,"journal":{"name":"Japanese journal of clinical oncology","volume":"93 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
BACKGROUNDThe use of adjuvant osimertinib for epidermal growth factor receptor (EGFR) mutants is expected to expand to earlier stage I in the future, potentially competing with the current standard of care, oral tegafur/uracil (UFT), in Japan. However, the effect of EGFR mutation status on the therapeutic effect of UFT remains unclear. This study was conducted as an exploratory analysis of a retrospective observational study that investigated the real-world data of postoperative adjuvant chemotherapy in Japan (CSPOR-LC03).METHODSBetween 2008 and 2013, 1812 patients with completely resected adenocarcinoma diagnosed as pathologic stage I (T1 > 2 cm, TNM classification, sixth edition) who have maintained organ function, and no history of other cancers were included. The primary endpoint was the 5-year disease-free survival (DFS) rate, and we compared this rate between four groups classified based on the administration of adjuvant UFT and EGFR mutation status.RESULTSOf the 933 (51%) patients with EGFR mutations, 394 underwent adjuvant UFT therapy. Of the 879 (49%) patients without EGFR mutations, 393 underwent adjuvant UFT therapy. The 5-year DFS of UFT+/EGFR+ and UFT-/EGFR+ patients were 82.0 and 87.1%, respectively, and those of UFT+/EGFR- and UFT-/EGFR- patients were 80.0 and 86.9%, respectively. DFS was significantly worse in the UFT+ group than in the UFT- group (P = 0.015). Adjuvant UFT therapy was not an independent prognostic factor for DFS, regardless of the EGFR mutation status.CONCLUSIONIn pathologic stage I (>2 cm) lung adenocarcinomas with EGFR mutation, the survival benefit of adjuvant UFT was not observed.
