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.

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.

OBJECTIVEThe objective of this study was to provide a convenient preoperative prediction of the risk of early postoperative mortality.MATERIALS AND METHODSThis retrospective study included patients who underwent surgery for spinal metastasis at our hospital between 2009 and 2021. Preoperative blood test data of all patients were collected, and the survival time was calculated by dividing the blood data. A multivariate analysis was conducted using a Cox proportional hazards model to identify prognostic factors.RESULTSThe study population included 83 patients (average: 64.5 years), 22 of whom died within 3 months. The most common lesion was the thoracic spine, and incomplete paralysis was observed in 57 patients. The surgical methods included posterior implant fixation (n = 17), posterior decompression (n = 31), and posterior decompression with fixation (n = 35). In the univariate analysis, the presence of abnormal values was significantly associated with postoperative survival in six preoperative blood collection items (hemoglobin, C-reactive protein, albumin, white blood cell, gamma-glutamyl transpeptidase, and lactate dehydrogenase). In a multivariate analysis, four test items (hemoglobin, C-reactive protein, white blood cell, and lactate dehydrogenase) were identified as independent prognostic factors.Comparing cases with ≥3 abnormal values among the above four items (high-risk group; n = 23) and those with ≤2 (low-risk group; n = 60), there was a significant difference in survival time. In addition, it was possible to predict cases of early death within 3 months after surgery with 73% sensitivity and 89% specificity.CONCLUSIONSThe study showed that four preoperative blood test abnormalities (hemoglobin, C-reactive protein white blood cell, and lactate dehydrogenase) indicated the possibility of early death within 3 months after surgery.

Objective: There is no consensus on the optimal treatment for patients with locoregional recurrence of esophageal cancer after surgery. The objective of this study was to investigate the outcomes and prognostic factors associated with salvage radiotherapy in patients with locoregional recurrence of esophageal cancer after surgery.
Methods: We reviewed 80 patients with locoregional recurrence of esophageal cancer after surgery who were treated with radiotherapy. The median dose was 60 Gy, and 29 patients (36%) received elective nodal irradiation. Fifty-three patients (66%) received concurrent chemotherapy (mostly 5-fluorouracil and cisplatin) during radiotherapy. Overall survival, progression-free survival and in-field recurrence rate were assessed.
Results: The median follow-up period was 17 months. Two-year overall survival, progression-free survival and in-field recurrence rate were 50.3%, 23.5% and 41.3%, respectively. On multivariate analysis, a maximum diameter of locoregional recurrence lesions <30 mm was associated with higher overall survival (P = 0.044). Disease-free interval between surgery and locoregional recurrence >14 months was associated with higher PFS (P = 0.003). Late grade 3 toxicities occurred in three patients (3.8%). No grade 4 or higher toxicity was observed.
Conclusions: Salvage radiotherapy demonstrated efficacy in achieving in-field control with acceptable toxicity. However, the high rate of out-of-field metastases led to poor progression-free survival and overall survival, particularly in cases involving large lesions and a short disease-free interval. A prospective study is warranted to establish a treatment strategy, particularly considering the combined use of effective anti-cancer drugs.

Colonoscopy is the gold standard for detecting and resecting adenomas or early stage cancers to reduce the incidence and mortality rates of colorectal cancer. In a recent observational study, texture and color enhancement imaging (TXI) was reported to improve polyp detection during colonoscopy. This randomized controlled trial involving six Japanese institutions aims to confirm the superiority of TXI over standard white-light imaging (WLI) in detecting colorectal lesions during colonoscopy. During the 1-year study period, 960 patients will be enrolled, with 480 patients in the TXI and WLI groups. The primary endpoint is the mean number of adenomas detected per procedure. The secondary endpoints include adenoma detection rate, advanced adenoma detection rate, polyp detection rate, flat polyp detection rate, depressed lesion detection rate, mean polyps detected per procedure, sessile serrated lesion (SSL) detection rate, mean SSLs detected per procedure and adverse events.

Background: In previous large-scale studies conducted through 2010, androgen deprivation therapy (ADT) was the most common initial treatment for prostate cancer patients in Japan. However, recent advancements in treatment technologies have significantly affected the management of prostate cancer in Japan. This study analyzed the trends in initial treatments for prostate cancer based on two nationwide surveys.
Methods: Two Japan-wide multi-institutional surveys, J-CaP2010 and J-CaP2016, were conducted to enroll patients newly histologically diagnosed with prostate cancer in 2010 and 2016-18, respectively. Both surveys included age at diagnosis, initial PSA level, ISUP Grade Group, TNM classification, and initial treatment for prostate cancer.
Results: J-CaP2010 included data from 8192 patients across 140 institutions, whereas J-CaP2016 included data from 21 841 patients across 186 institutions. In J-CaP2016, the proportion of radical prostatectomy (RP) and radiation therapy (RT) in the initial treatment increased (from 32% to 36% and 21% to 26%, respectively), whereas the proportion of ADT decreased (from 40% to 29%) compared with those in J-CaP2010. The increase in RP or RT was noticeable in patients aged 75 years and older (from 20% to 38%) and those with high-risk localized cancer (from 58% to 74%) or locally advanced cancer (from 38% to 56%). The proportion of active surveillance or watchful waiting increased in patients with low-risk localized cancer (from 21% to 41%). The proportion of robot-assisted RP within all RPs and the proportion of intensity-modulated RT within all RTs increased remarkably (from 2.3% to 78% and 20% to 50%, respectively).
Conclusions: In Japan, RP and RT have increased as initial treatments for prostate cancer, whereas ADT has decreased. Consequently, RP has emerged as the most commonly selected initial treatment, replacing ADT.

Background: Cholinesterase is a classical nutritional and inflammatory marker. The aim of the present study was to evaluate the value of cholinesterase as a predictive marker for postoperative skeletal muscle loss after gastrectomy for gastric cancer.
Methods: The study comprised 68 patients who had undergone gastrectomy for gastric cancer. Skeletal muscle mass was evaluated using skeletal mass index, and major skeletal muscle loss was defined as less than or equal to the median change rate (1-year postoperative/preoperative) of skeletal mass index in all patients. We explored the relationship between postoperative major skeletal muscle loss and disease-free survival and overall survival. Then we investigated the relationship between change rate of skeletal muscle index and serum cholinesterase levels after gastrectomy.
Results: The median value of change rate of skeletal mass index was 0.93. Postoperative major skeletal muscle loss was significantly associated with disease-free survival after gastrectomy (P = 0.003). Although major skeletal muscle loss had worse overall survival, it was not significant (P = 0.058). The change rate of skeletal mass index and cholinesterase had a stronger positive correlation compared with other nutritional indices according to Spearman's rank correlation coefficient (r = 0.438, P ≤ 0.001).
Conclusion: Evaluation of serum cholinesterase levels may be valuable for predicting postoperative skeletal muscle loss after gastrectomy, suggesting the importance of cholinesterase in postoperative nutritional management of patients with gastric cancer.
