Abstract
BACKGROUND Evidence regarding long-term therapeutic outcomes and disease-specific survival (DSS) in Extramammary Paget's disease (EMPD) is limited. OBJECTIVES To assess the DSS and outcomes of surgical and nonsurgical therapeutic modalities in a large cohort of EMPD patients. METHODS Retrospective chart review of EMPD patients from 20 Spanish tertiary care hospitals. RESULTS Data on 249 patients with a median follow-up of 60 months were analyzed. The estimated 5-, 10-, and 15-year DSS was 95.9%, 92.9%, and 88.5%, respectively. A significantly lower DSS was observed in patients showing deep dermal invasion (≥1 mm) or metastatic disease (P < .05). A ≥50% reduction in EMPD lesion size was achieved in 100% and 75.3% of patients treated with surgery and topical therapies, respectively. Tumor-free resection margins were obtained in 42.4% of the patients after wide local excision (WLE). The 5-year recurrence-free survival after Mohs micrographic surgery (MMS), WLE with tumor-free margins, WLE with positive margins, radiotherapy, and topical treatments was 63.0%, 51.4%, 20.4%, 30.1%, and 20.8%, respectively. LIMITATIONS Retrospective design. CONCLUSIONS EMPD is usually a chronic condition with favorable prognosis. MMS represents the therapeutic alternative with the greatest efficacy for the disease. Recurrence rates in patients with positive margins after WLE are similar to the ones observed in patients treated with topical agents.

Abstract
Laser Interstitial Thermotherapy is a minimally invasive treatment option in neurosurgery for intracranial tumors, including recurrent gliomas. The technique employs the thermal ablation of target tissue to achieve tumor control with real-time monitoring of the extent by magnetic resonance thermometry, allowing targeted thermal injury to the lesion. Laser Interstitial Thermotherapy has gained interest as a treatment option for recurrent gliomas due to its minimally invasive nature, shorter recovery times, ability to be used even in patients with numerous comorbidities, and potential to provide local tumor control. It can be used as a standalone treatment or combined with other therapies, such as chemotherapy or radiation therapy. We describe the most recent updates regarding several studies and case reports that have evaluated the efficacy and safety of Laser Interstitial Thermotherapy for recurrent gliomas. These studies have reported different outcomes, with some demonstrating promising results in terms of tumor control and patient survival, while others have shown mixed outcomes. The success of Laser Interstitial Thermotherapy depends on various factors, including tumor characteristics, patient selection, and the experience of the surgical team, but the future direction of treatment of recurrent gliomas will include a combined approach, comprising Laser Interstitial Thermotherapy, particularly in deep-seated brain regions. Well-designed prospective studies will be needed to establish with certainty the role of Laser Interstitial Thermotherapy in the treatment of recurrent glioma.

Abstract
Radiation-induced hemorrhagic cystitis is a late complication of radiotherapy, and in rare cases, refractory. Refractory bleeding may not be resolved by transurethral electrocoagulation (TUEC) or hyperbaric oxygen (HBO) therapy and requires transcatheter arterial embolization (TAE) or urinary diversion. Here, we report two cases of radiation-induced hemorrhagic cystitis successfully treated with TAE. Case 1 was a 61-yearold man who underwent total prostatectomy for prostate cancer followed by salvage radiation therapy. The patient developed radiation-induced hemorrhagic cystitis 2 years and 3 months after radiotherapy. After no improvement with TUEC and HBO, TAE was performed. Case 2 was a 78-year-old man who underwent total prostatectomy followed by salvage radiation therapy and developed radiation-induced hemorrhagic cystitis 12 years later. TAE was performed after no improvement with HBO. TAE proved successful in both patients, and there was no relapse. TAE is a potential treatment option for refractory radiation-induced hemorrhagic cystitis.

Abstract
Patients with stage 4N neuroblastoma (distant metastases limited to lymph nodes) stand out as virtually the only survivors of high-risk neuroblastoma (HR-NB) before myeloablative therapy (MAT) and immunotherapy with anti-GD2 monoclonal antibodies (mAbs) became standard. Because no report presents more recent results with 4N, we analyzed our large 4N experience. All 51 pediatric 4N patients (<18 years old) diagnosed 1985 to 2021 were reviewed. HR-NB included MYCN-nonamplified 4N diagnosed at age ≥18 months and MYCN-amplified 4N. Among 34 MYCN-nonamplified high-risk patients, 20 are relapse-free 1.5+ to 37.5+ (median 12.5+) years post-diagnosis, including 13 without prior MAT and 5 treated with little (1 cycle; n = 2) or no mAb (n = 3), while 14 patients (7 post-MAT, 8 post-mAbs) relapsed (all soft tissue). Of 15 MYCN-amplified 4N patients, 7 are relapse-free 2.1+ to 26.4+ (median 11.6+) years from the start of chemotherapy (all received mAbs; 3 underwent MAT) and 4 are in second remission 4.2+ to 21.8+ years postrelapse (all soft tissue). Statistical analyses showed no significant association of survival with either MAT or mAbs for MYCN-nonamplified HR-NB; small numbers prevented these analyses for MYCN-amplified patients. The two patients with intermediate-risk 4N (14-months-old) are relapse-free 7+ years postresection of primary tumors; distant disease spontaneously regressed. The natural history of 4N is marked by NB confined to soft tissue without early relapse in bones or bone marrow, where mAbs have proven efficacy. These findings plus curability without MAT, as seen elsewhere and at our center, support consideration of treatment reduction for MYCN-nonamplified 4N.

Abstract
Background Follicular lymphoma (FL), a common indolent B-cell lymphoma, has the potential to transform into an aggressive lymphoma, such as diffuse large B-cell lymphoma (DLBCL). The outcome of patients with transformed follicular lymphoma (tFL) is poor, especially in patients with transformed lymphoma after chemotherapy and patients with progression within 24 months (POD24). Chimeric antigen receptor (CAR) T-cell therapy combined with autologous stem cell transplantation (ASCT) has promising antitumor efficacy. Case presentation Here, we described a 39-year-old male patient who was initially diagnosed with FL that transformed into DLBCL with POD24, CD20 negativity, TP53 mutation, and a bulky mass after 3 lines of therapy, all of which were adverse prognostic factors. We applied a combination approach: CD19 CAR T-cell infusion following ASCT. Ibrutinib was administered continuously to enhance efficacy, DHAP was administered as a salvage chemotherapy, and ICE was administered as a bridging regimen. The patient underwent BEAM conditioning on days -7~ -1, a total of 3.8 × 106/kg CD34+ stem cells were infused on days 01~02, and a total of 108 CAR T cells (relmacabtagene autoleucel, relma-cel, JWCAR029) were infused on day 03. The patient experienced grade 2 cytokine release syndrome (CRS), manifesting as fever and hypotension according to institutional standards. There was no immune effector cell-associated neurotoxicity syndrome (ICANS) after CAR T-cell infusion. Finally, the patient achieved CMR at +1 month, which has been maintained without any other adverse effects. Conclusion This case highlights the amazing efficacy of CD19 CAR T-cell therapy following ASCT for R/R tFL, thus providing new insight on therapeutic strategies for the future.

Abstract
PURPOSE Locoregional recurrence of esophageal carcinoma after neoadjuvant therapy and en bloc esophagectomy, although uncommon, is challenging to manage. Currently, there are no standard treatment approaches prompting many health care providers to adopt a palliative approach. We describe our experience and outcomes of treating this specific group of patients with a focus on salvage curative intent local therapy. METHODS All patients undergoing en bloc esophagectomy following neoadjuvant therapy between 2007 and 2017 at the McGill University Health Centre, a tertiary referral center for esophageal cancer, were identified. Patient follow-up included a structured surveillance protocol with serial endoscopic and cross-sectional imaging studies. Local recurrence was defined as histologically confirmed recurrences at the anastomosis. Regional recurrence was defined as radiological evidence of celiac, mediastinal, or para-esophageal/conduit lymphadenopathy. Demographic, pathologic, therapeutic variables were extracted as well as disease free and overall survival. RESULTS Of 755 patients identified, locoregional recurrences occurred in 27 patients (3.6%) of whom 18 were included in the analysis. The median disease-free survival post index operation was 15 months (IQR 10-23). The sites of recurrence were local (6/18, 33.3%); regional (8/18, 44.4%); and locoregional (4, 22.2%). Chemoradiation was the most common modality used to treat recurrence (10/18, 55.6%) whilst 4 (22.2%) underwent surgery. Following treatment for locoregional recurrence, 1-year overall survival was 61.1% and at 5 years was 22.2%. CONCLUSION Consolidative salvage local therapy for locoregional recurrence after en bloc esophagectomy is feasible and can entail prolonged survival in a subset of patients.

Abstract
OBJECTIVES Sinonasal undifferentiated carcinoma (SNUC) is a rare and aggressive disease requiring multimodal treatment, and multiple new entities once included in the spectrum of SNUC, such as SWI/SNF-deficient carcinomas, are emerging. We aimed to provide new data regarding the role of chemotherapy and surgery and the prognostic factors of disease-free survival. METHODS This study was based on data from the REFCOR database and included patients with SNUC treated with curative intent from 2007 to 2021 across 22 centres in France. RESULTS A total of 80 patients were included in the analysis. Among the entire cohort, the 5-year disease-free survival (DFS) and overall survival (OS) rates were 58% and 63%, respectively. Of 100% of the patients treated with irradiation, 29% underwent surgery, 56% neoadjuvant chemotherapy (82% had either a partial or a complete response) and 76% chemoradiotherapy. No treatment modality was associated with a better OS or DFS, including surgery (p = 0.34). There was a trend for a better DFS for the patients treated with chemotherapy (neoadjuvant or concomitant, p = 0.062). Overall survival at 3 years was 58% for SWI/SNF deficient group and 86% for non deficient group (p = 0.14). The locoregional relapse rate without distant metastases was 21% in the exclusive radiotherapy group and 26% in the surgery group. Grade 3 or higher toxicities concerned 9%, 32% and 29% of patients for surgery, radiotherapy and chemotherapy respectively. CONCLUSION In the management of localised SNUC among all patients treated with irradiation, surgery yielded no benefit, whereas the addition of chemotherapy tended to improve disease-free survival.

Abstract
There are different initial situations in the treatment of local or locoregional recurrences, secondary carcinomas or residual squamous cell carcinomas of the head and neck region after primary therapy. The majority of patients with locoregional recurrences have had prior treatment consisting of surgery and/or postoperative radiotherapy or radiochemotherapy or primary radiotherapy or radiochemotherapy. In any case, it is a matter of new tumor growth in a previously treated area, which must be taken into account for the therapy decision. The biological backgrounds are diverse and are described in more detail and clinically classified in the present work.

Abstract
OBJECTIVE Fear of Cancer Recurrence (FCR) is highly prevalent among cancer survivors and leads to decreased quality of life and increased healthcare costs. We assessed the effectiveness of a guided online primary care intervention for FCR, compared to waiting list. METHODS In this RCT, participants were recruited online and randomised 1:1. All adults who finished successful curative cancer treatment between 3 months and 10 years ago, wanted support for FCR, and had sufficient Dutch skills were eligible. The intervention consisted of a 10-week online programme and three to five video calling sessions with a trained mental health worker. After 6 months, the control group received the same intervention. The primary outcome was the difference between the groups in the change in FCR severity from baseline (T0) to 6 months (T2), measured online with the short form of the Fear of Cancer Recurrence Inventory. RESULTS One hundred and seventy-three participants were enroled and randomised to the intervention (n = 86) or control group (n = 87). FCR severity dropped 2.1 points more in the intervention group than in the control group (2.7 points (SD = 3.9) versus 0.6 points (SD = 3.6), t(154) = 3.4, p = 0.0007). General mental well-being also improved significantly in the intervention group and remained stable in the control group. These improvements remained at 10 months follow up. CONCLUSIONS This easily accessible and relatively inexpensive intervention effectively reduces FCR and has potential to replace or precede existing more intensive psychological treatments, improving patients' access to care. TRIAL REGISTRATION The trial was prospectively registered in the Netherlands Trial Register on 25-02-2019 with number NL7573.

Abstract
Objective:To explore the clinical manifestations,the type of pathology, treatment and prognosis of laryngeal rhabdomyosarcoma, and to enhance the understanding of the clinical characteristics of the disease, while improving the diagnosis rateand reducing the misdiagnosis rate, in order to explore effective diagnosis and treatment methods. Methods:A retrospective analysis was conducted on the clinical data of 5 cases of laryngeal rhabdomyosarcoma treated in the First Affiliated Hospital of Zhengzhou University from May 2015 to May 2021. Results:All 5 cases of laryngeal rhabdomyosarcoma were misdiagnosed in the early stage. with tumors mostly occurring in the vocal cords and appearing as smooth mass. The clinical symptoms were mostly hoarseness. According to pathological classification, three cases were embryonic type, one case was polymorphic type, and one case was spindle type.Three patients died due to tumor recurrence, one patient had multiple systemic metastases, and another patient who underwent surgical resection in the early stage and supplemented with postoperative radiotherapy and chemotherapyhas been followed up to date without recurrence. Conclusion:Laryngeal rhabdomyosarcoma has low incidence rate, high malignancy degree and poor prognosis. It is easy to be misdiagnosed as a benign mass. Extensive surgical resection combined with radiotherapy and chemotherapy should be performed as soon as possible after diagnosis.

Abstract
INTRODUCTION The purpose of this study is to analyze the impact of a virtual multidisciplinary sarcoma case conference (VMSCC) on the outcomes of dermatofibrosarcoma protuberans (DFSP). METHODS We compared margin status after surgery and disease-free survival (DFS) on two cohorts of patients with DFSP, one diagnosed from 2010 to 2015 and one from 2016 to 2020 (before and after virtual multidisciplinary sarcoma case conference (VMSCC) within Kaiser Permanente Northern California (KPNC), using Kaplan-Meier curves and Cox proportional hazard regression models. RESULTS There was no significant difference between the two cohorts on demographics, tumor location, type of surgery, receipt of radiation, receipt of imatinib, or size of tumor. However, the percent of patients with positive margin after final surgery and the percent of local recurrence were significantly different: 6.5% and 6.3% for the 2010-2015 cohort, and .8% and 0% for the 2016-2020 cohort, respectively. CONCLUSION Our data suggest that the outcomes of DFSP improved significantly after the implementation of VMSCC.

Abstract
Emerging biological and clinical data, along with advances in new technologies, have exposed the mechanistic diversity in post-haematopoietic stem cell transplant (HCT) relapse. Post-HCT relapse mechanisms are relevant for guiding sophisticated selection of therapeutic interventions and identification of areas for further research. Clonal evolution and emergence of resistant leukemic strains is a common mechanism shared by relapse post-chemotherapy and post-HCT, other mechanisms such as leukemic immune escape and donor T cell exhaustion are unique entities to post-HCT relapse. Due to diversity in the mechanisms behind post-HCT relapse, the subsequent clinical approach relies on clinician discretion, rather than objective evidence. Lack of standardized selection based on post-HCT relapse mechanism(s) could be a contributing factor to observed poor outcomes. Therapeutic strategies including donor lymphocyte infusion (DLI), second transplant, immunotherapies, hypomethylating agents, and targeted strategies are supported options and efficacy may be enhanced when post-HCT AML relapse mechanism is established and guides treatment selection. This review aims, through compilation of supporting studies, to describe mechanisms of post-HCT relapse and their implications for subsequent treatment selection and inspiration for future research.

Abstract
RATIONALE AND OBJECTIVES Bronchial arterial chemoembolization (BACE) was deemed as an effective and safe approach for advanced standard treatment-ineligible/rejected lung cancer patients. However, the therapeutic outcome of BACE varies greatly and there is no reliable prognostic tool in clinical practice. This study aimed to investigate the effectiveness of radiomics features in predicting tumor recurrence after BACE treatment in lung cancer patients. MATERIALS AND METHODS A total of 116 patients with pathologically confirmed lung cancer who received BACE treatment were retrospectively recruited. All patients underwent contrast-enhanced CT within 2 weeks before BACE treatment and were followed up for more than 6 months. We conducted a machine learning-based characterization of each lesion on the preoperative contrast-enhanced CT images. In the training cohort, recurrence-related radiomics features were screened by least absolute shrinkage and selection operator (LASSO) regression. Three predictive radiomics signatures were built with linear discriminant analysis (LDA), support vector machine (SVM) and logistic regression (LR) algorithms, respectively. Univariate and multivariate LR analyses were performed to select the independent clinical predictors for recurrence. The radiomics signature with best predictive performance was integrated with the clinical predictors to form a combined model, which was visualized as a nomogram. The performance of the combined model was assessed by receiver operating characteristic curve (ROC), calibration curve, and decision curve analysis (DCA). RESULTS Nine recurrence-related radiomics features were screened out, and three radiomics signatures (RadscoreLDA, RadscoreSVM and RadscoreLR) were built based on these features. Patients were classified into the low-risk and high-risk groups based on the optimal threshold of three signatures. Progression-free survival (PFS) analysis showed that patients of low-risk group achieved longer PFS than patients of high-risk group (P < 0.05). The combined model including RadscoreLDA and independent clinical predictors (tumor size, carcinoembryonic antigen and pro-gastrin releasing peptide) achieved the best predictive performance for recurrence after BACE treatment. It yields AUCs of 0.865 and 0.867 in the training and validation cohorts, with accuracy (ACC) of 0.804 and 0.750, respectively. Calibration curves indicated that the probability of recurrence predicted by the model fits well with the actual recurrence probability. DCA showed that the radiomics nomogram was clinically useful. CONCLUSION The radiomics and clinical predictors-based nomogram can predict tumor recurrence after BACE treatment effectively, which allowing oncologists to identify potential recurrence and enable better patient management and clinical decision-making.

Abstract
BACKGROUND Updated knowledge about the rates of recurrence and time to recurrence following curative treatment of colorectal cancer is essential to secure better patient information on prognosis, to serve as a premise in the discussion on adjuvant chemotherapy, and help to properly scale the intensity and length of follow-up. METHODS This is a population-based study investigating aspects on first recurrence after radical treatment of clinical stages I-III of colorectal cancer in Central-Norway during 2001-2015. To reveal any time-trends, data were stratified by the time periods 2001-2005, 2006-2010 and 2011-2015. The cumulative incidence of first recurrence was calculated, treating death of unrelated causes as a competing event. Multivariable Cox analyses were done to calculate cause specific hazard ratios (HR) for risk of recurrence. RESULTS At a minimum follow-up of six years, a first recurrence was detected in 1,113/5,556 patients at risk (20.0%). The recurrence rate was reduced from 23.6% in the first time period, through 20.0% in the second, and to 17.2% in the last, p < 0.001. The reduction applied to all tumor locations, to pathological disease stages II and III, to both gender, across different tumor differentiations, and to both elective and emergency surgery. In multivariable analyses time period, gender, disease stage, and tumor differentiation were significant determinants for risk of recurrence. CONCLUSIONS The rate of first recurrence after curative surgery for colorectal cancer was substantially reduced from 2001 to 2015. The reason for the reduction could not be attributed to a single factor only. A combined effect of several incremental improvements, such as an increased use of preoperative radiation for rectal cancers, improved adjuvant chemotherapy for colon cancer, and a reduced proportion of emergency surgery, is suggested.

Abstract
Recurrent glioma treatment is challenging due to molecular heterogeneity and treatment resistance commonly observed in these tumors. Researchers are actively pursuing new therapeutic strategies. Oncolytic viruses have emerged as a promising option. Oncolytic viruses selectively replicate within tumor cells, destroying them and stimulating the immune system for an enhanced anticancer response. Among Oncolytic viruses investigated for recurrent gliomas, oncolytic herpes simplex virus and oncolytic adenovirus show notable potential. Genetic modifications play a crucial role in optimizing their therapeutic efficacy. Different generations of replicative conditioned oncolytic human adenovirus and oncolytic HSV have been developed, incorporating specific modifications to enhance tumor selectivity, replication efficiency, and immune activation. This review article summarizes these genetic modifications, offering insights into the underlying mechanisms of Oncolytic viruses' therapy. It also aims to identify strategies for further enhancing the therapeutic benefits of Oncolytic viruses. However, it is important to acknowledge that additional research and clinical trials are necessary to establish the safety, efficacy, and optimal utilization of Oncolytic viruses in treating recurrent glioblastoma.

Abstract
BACKGROUND AND AIM Some patients with high-risk non-muscle-invasive bladder cancer (NMIBC) are unable to receive adequate BCG instillations due to intolerance. In this study we aimed to investigate the efficacy and tolerability of hyperthermic intravesical chemotherapy (HIVEC®) treatment using Mitomycin C (MMC) in BCG-intolerant NMIBC patients. METHODS Retrospectively collected data from a total of 22 high-risk papillary NMIBC patients who received adjuvant HIVEC therapy for BCG intolerance were analyzed. The primary outcomes of the study were recurrence-free survival (RFS), time to recurrence, progression-free survival (PFS), and time to progression following initial TURB. Detection of histologically confirmed urothelial carcinoma during follow-up was considered as recurrence, while detection of muscle-invasive disease was defined as progression. The secondary outcome was adverse events of HIVEC treatment. RESULTS The median follow-up was 32.2 (IQR: 17.8-42.8) months. The RFS and PFS rates were 81.8% and 95.4%, respectively. The mean time to tumor recurrence and progression was 29.2 ± 14.3 and 16.7 months, respectively. Adverse events occurred in 50% of patients, and 95% of adverse events were mild to moderate. CONCLUSION This study demonstrated that adjuvant HIVEC with MMC is an effective and safe alternative bladder sparing treatment in BCG intolerant high risk papillary NMIBC patients.

Abstract
Majority of non-Hodgkin lymphoma (NHL) patients who achieve partial response (PR) or stable disease (SD) to CAR T-cell therapy (CAR T) on day +30 progress and only 30% achieve spontaneous complete response (CR). This study is the first to evaluate the role of consolidative radiotherapy (cRT) for residual fluorodeoxyglucose (FDG) activity on day +30 post- CAR T in NHL. We retrospectively reviewed 61 patients with NHL who received CAR T and achieved PR or SD on day +30. Progression-free survival (PFS), overall survival (OS), and local relapse-free survival (LRFS) were assessed from CAR T infusion. cRT was defined as comprehensive - treated all FDG-avid sites - or focal. Following day +30 positron emission tomography scan, 45 patients were observed and 16 received cRT. Fifteen (33%) observed patients achieved spontaneous CR, and 27 (60%) progressed with all relapses involving initial sites of residual FDG activity. Ten (63%) cRT patients achieved CR, and four (25%) progressed with no relapses in the irradiated sites. The 2-year LRFS was 100% in the cRT sites and 31% in the observed sites (P<0.001). The 2-year PFS was 73% and 37% (P=0.025) and the 2-year OS was 78% and 43% (P=0.12) in the cRT and observation groups, respectively. Patients receiving comprehensive cRT (n=13) had superior 2- year PFS (83% vs. 37%; P=0.008) and 2-year OS (86% vs. 43%; P=0.047) compared to observed or focal cRT patients (n=48). NHL patients with residual FDG activity following CAR T are at high risk of local progression. cRT for residual FDG activity on day +30 post-CAR T appears to alter the pattern of relapse and improve LRFS and PFS.

Abstract
Imaging of head and neck cancer at initial staging and as part of post-treatment surveillance is a key component of patient care as it guides treatment strategy and aids determination of prognosis. Head and neck cancer includes a heterogenous group of malignancies encompassing several anatomic sites and histologies, with squamous cell carcinoma the most common. Together this comprises the seventh most common cancer worldwide. At initial staging comprehensive imaging delineating the anatomic extent of the primary site, while also assessing the nodal involvement of the neck is necessary. The treatment of head and neck cancer often includes a combination of surgery, radiation, and chemotherapy. Post-treatment imaging is tailored for the evaluation of treatment response and early detection of local, locoregional, and distant recurrent tumor. Cross-sectional imaging with CT or MRI is recommended for the detailed anatomic delineation of the primary site. PET/CT provides complementary metabolic information and can map systemic involvement. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
BACKGROUND The outcome of children with refractory or relapsed soft tissue sarcoma (STS) is extremely poor. Whereas larger clinical trials evaluated specific treatment modalities, real-life data on individual multimodal therapeutic strategies, given alone or in combination, are scarce. PATIENTS AND METHODS We retrospectively analyzed the clinical course of 18 pediatric patients with progression of or relapsed STS treated between 2008 and 2018 in our institution. RESULTS A total of 18 patients (median age 12.4 years) suffered from progression or relapse of alveolar (n=7), embryonal (n=5), undifferentiated (n=2) rhabdomyosarcoma or desmoplastic small round cell tumor (n=4). 14 patents had an initial stage IV disease. All but one patient died. Median survival was 12.5 months. Shortest survival was seen in patients with systemic progression of the disease, longest in patients with local relapse. Patients with an Oberlin score<2 at the time of relapse had a significant longer time of survival than those with a score≥2. No significant advantage of a specific therapeutic modality was observed. DISCUSSION We critically analyzed the clinical course in the real-life setting, in which various treatment options were applied to an individual patient according to the best of available data. We observed that some patients died within a short period of time despite multiple treatment modalities, which underlines the need for better prognostic parameters. CONCLUSION In addition to well characterized clinical factors such as local or systemic relapse, the Oberlin score could be helpful in counselling patients and their families for choosing the best strategy of care.

Abstract
Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is a treatment option for peritoneal carcinomatosis (PC) from colorectal cancer (CRC), which is otherwise a terminal stage of disease. Nevertheless, survival outcomes are only marginally superior to other treatments. This fact highlights the need for better strategies to control intra-abdominal disease recurrence after CRS-HIPEC, including the complementary use of immunotherapies. The aim of this study was therefore to investigate the immune phenotype of T cells in patients with PC. Fifty three patients with CRC (34 patients with PC and 19 patients without PC) were enrolled in a prospective study (clinicaltrials.gov: NCT04108936). Peripheral blood and omental fat were collected to isolate peripheral blood mononuclear cells (PBMCs) and adipose tissue mononuclear cells (ATMCs). These cells were analysed by flow cytometry using a panel focused upon T cell memory differentiation and exhaustion markers. We found a more naïve profile for CD8+ T cells in peripheral blood and intra-abdominal fat of PC patients compared to comparator group (CG) patients. Furthermore, there was an over-representation of CD4+ T cells expressing inhibitory receptors in adipose tissue of PC patients, but not in blood. Our description of intraperitoneal T cell subsets gives us a better understanding of how peritoneal carcinomatosis shapes local immune responses.

Abstract
BACKGROUND Rhabdomyosarcoma is the most common soft tissue sarcoma in children, but rare in adults. Para-meningeal rhabdomyosarcoma in head and neck (PM-HNRMS) is less applicable for surgery due to the anatomic reason. PM-HNRMS has a poor prognosis in children. However, its clinical outcomes remain unclear in adults due to the rarity. Further, there is almost no detailed data about salvage therapy. METHODS We retrospectively examined the adult patients with PM-HNRMS treated at institutions belonging to the Kyushu Medical Oncology Group from 2009 to 2022. We evaluated the overall survival (OS) and progression-free survival (PFS) of the patients who received a first-line therapy. We also reviewed the clinical outcomes of patients who progressed against a first-line therapy and received salvage therapy. RESULTS Total 11 patients of PM-HNRMS received a first-line therapy. The characteristics were as follows: median age: 38 years (range 25 - 63 years), histology (alveolar/spindle): 10/1, and risk group (intermediate/high): 7/4. As a first-line therapy, VAC and ARST0431-based regimen was performed in 10 and 1 patients, respectively. During a first-line therapy, definitive radiation for all lesions were performed in seven patients. The median PFS was 14.2 months (95%CI: 6.0 - 25.8 months): 17.1 months (95%CI: 6.0 - not reached (NR)) for patients with stage I-III and 8.5 months (95%CI: 5.2 - 25.8 months) for patients with stage IV. The 1-year and 3-year PFS rates were 54.5% and 11.3% for all patients. Median OS in all patients was 40.8 months (95%CI: 12.1 months-NR): 40.8 months (95%CI: 12.1 - NR) for patients with stage I-III and NR for patients with stage IV. The 5-year OS rate was 48.5% for all patients. Among seven patients who received salvage therapy, three are still alive, two of whom remain disease-free for over 4 years after completion of the last therapy. Those two patients received multi-modal therapy including local therapy for all detected lesions. CONCLUSION The cure rate of adult PM-HNRMS is low in spite of a first-line therapy in this study. Salvage therapy might prolong the survival in patients who received the multi-modal therapy including local therapy for all detected lesions.

Abstract
OBJECTIVE To describe the radiological characteristics of hepatocellular carcinoma (HCC) lesions that achieved a complete response following drug-eluting bead transarterial chemoembolization (DEB-TACE) preceding liver transplantation. METHODS This single-center case-control study enrolled patients with hepatocellular carcinoma who underwent neoadjuvant DEB-TACE therapy, were followed up with contrast-enhanced magnetic resonance imaging or computed tomography, and were successively evaluated according to the modified Response Evaluation Criteria in Solid Tumors. The HCCs were divided into two groups based on their diameter (Group A: ≤3cm; Group B: 3cm). Viability was assessed using the Kaplan-Meier method according to tumor size categories. The relationship between tumor variables was analyzed using bivariate Cox regression. RESULTS Three-hundred and twenty-eight patients with 667 hepatocellular carcinomas who underwent their first DEB-TACE session were enrolled. A total of 105 hepatocellular carcinomas in 59 patients exhibited complete response after the initial DEB-TACE session and were divided into Group A (92 HCCs) and Group B (13 HCCs). The diameter in Group A decreased significantly compared to the pre-procedure size until the second assessment (p<0.001), with no subsequent reduction in diameter, despite maintaining a complete response. In Group B, the reduction in diameter remained significant compared with the initial value until the sixth imaging evaluation (p=0.014). The average reduction was 45.1% for Group B and a maximum of 14.9% in Group A. CONCLUSION HCCs >3cm exhibited a greater reduction in size and a longer time to recurrence. HCCs ≤3cm had a shorter relapse time. The recurrence rates were similar. These findings may aid in planning for liver transplantation.

Abstract
To clarify the role of allogeneic hematopoietic stem-cell transplantation (allo-HSCT) in the chimeric antigen receptor T-cell therapy era, we analyzed the clinical characteristics and outcomes of 52 patients treated with allo-HSCT with relapsed/refractory diffuse large B cell lymphoma. Most enrolled patients had previously undergone intensive treatments, the median number of chemotherapy lines was 4, and the median time from diagnosis to allo-HSCT was 27.1 months. Patients were divided into remission-achieved (n = 30) and active-disease (n = 22) groups before allo-HSCT. Over a median follow-up period of 38.3 months, overall survival (OS) and event-free survival (EFS) rates were 38.4% and 30.6%, respectively. The cumulative incidence of relapse (CIR) and the non-relapsed mortality (NRM) were 36.7% and 32.7%, respectively. OS, EFS, and graft-versus-host disease-free, relapse-free survival (GRFS) outcomes were significantly superior in the remission-achieved group with lower CIR. In a multivariate analysis, a shorter interval from diagnosis to allo-HSCT reflected relatively rapid disease progression and showed significantly poor OS and EFS with higher CIR. Patients with active disease had significantly lower EFS, GRFS, and higher CIR. Previous autologous stem-cell transplantation was associated with better GRFS. Allo-HSCT is an established modality with a prominent group of cured patients and still has a role in the CAR T-cell era, particularly given its acceptable clinical outcomes in young patients with chemo-susceptible disease.
