Background: A majority of esophageal carcinoma patients are diagnosed at an advanced stage and are no longer suitable for surgical resection. Drug-eluting beads transarterial chemoembolization (DEB-TACE) with oxaliplatin-loaded CalliSpheres beads (CB) have been used for advanced hepatocellular carcinoma and lung cancer, but they have not been reported for the treatment of unresectable or recurrent esophageal carcinoma., Methods: DEB-TACE was performed on 22 patients with unresectable or recurrent esophageal carcinoma between March 2019 and May 2022. The clinical outcomes, complications, and efficacy were retrospectively recorded and analyzed., Results: A total of 39 sessions of DEB-TACE were performed in 22 patients, with a technical success rate of 92.3% and clinical success rate of 65.0%. No severe complications such as procedure-related death, esophageal rupture or paraplegia were observed. Complete response, partial response, and stable disease were observed in 14.3% (2/14), 42.9% (6/14), and 21.4% (3/14) of patients 6 months after DEB-TACE, respectively. The objective response rates were 62.5%, 42.9% and 57.1% respectively at 1-, 3-, and 6-month after DEB-TACE. Subsequent interventional treatments were administered to 12 patients, including DEB-TACE for hepatic metastasis in 3 (13.6%), esophageal stenting in 5 (22.7%), and airway stent placement in 5 (22.7%). Two patients were lost to follow up. A total of 9 patients died due to tumor progression (n = 5), pneumatic infection (n = 1), and tumor-related massive esophageal hemorrhage (n = 3). The median overall survivals were 13.9 months and 26.5 months from the first session of DEB-TACE and the diagnosis of esophageal carcinoma, respectively., Conclusions: DEB-TACE with oxaliplatin-loaded CB is suggested as a safe and effective treatment of unresectable or recurrent esophageal carcinoma, and more studies are required to confirm its efficacy and safety., (© 2024.

CAR T-cell therapy is a recent therapeutic advancement that has transformed the management of relapsed/refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL). To date, there are 2 FDA-approved CAR-T products for R/R B-ALL: tisagenlecleucel in patients aged <26 years and brexucabtagene autoleucel in those aged ≥18 years. This review summarizes the pivotal clinical trials that led to FDA approval of these 2 products and highlight emerging data addressing key questions pertinent to CAR-T utilization in the rapidly evolving landscape of R/R ALL management. These include optimal sequencing of CAR-T among other novel immunotherapeutic agents, the role of consolidation and maintenance following CAR-T, novel CAR-T constructs currently under clinical development, and strategies to optimize use of commercially available CAR-T products to improve patient outcomes.

Background: Recurrent squamous cell carcinoma (SCC) of the head and neck (SCCHN) remains a formidable clinical challenge despite available treatments. The phosphatidylinositol 3-kinase (PI3K) pathway has been identified as a potential therapeutic target, and alpelisib, a selective PI3Kα inhibitor, has demonstrated efficacy in certain malignancies. Combining this targeted therapy with immunotherapy has been suggested in previous studies as a promising strategy to bolster the immune response against cancer., Cases: A 69-year-old woman with locoregional recurrence of PIK3CA-mutated SCC of the left maxilla and cervical nodal metastases. Several chemotherapeutic regimens, including cisplatin, docetaxel, 5FU, chemoradiotherapy, and mono-immunotherapy, resulted in disease progression. Alpelisib combined with pembrolizumab led to a sustained response for 9 months. A 58-year-old man with recurrent metastatic PIK3CA-mutated SCC of the oropharynx, involving the left lung, hilar, and mediastinal lymph nodes. Despite prior palliative radiation and platinum-based chemotherapy with pembrolizumab and cetuximab, treatment with alpelisib and nivolumab resulted in a partial response. Severe hyperglycemia and rash led to treatment discontinuation., Conclusion: Our findings highlight the potential of this innovative therapeutic combination, suggesting a need for further investigations in this setting., (© 2024 The Author(s).

Purpose: This study aimed to use propensity score matching (PSM) to explore the long-term outcomes and failure patterns in locally advanced rectal cancer (LARC) patients with positive versus negative lateral pelvic lymph node (LPLN)., Materials and Methods: Patients with LARC were retrospectively divided into LPLN-positive and LPLN-negative groups. Clinical characteristics were compared between the groups using the chi-square test. PSM was applied to balance these differences. Progression-free survival (PFS) and overall survival (OS), and local-regional recurrence (LRR) and distant metastasis (DM) rates were compared between the groups using the Kaplan-Meier method and log-rank tests., Results: A total of 651 LARC patients were included, 160 (24.6%) of whom had positive LPLN and 491 (75.4%) had negative LPLN. Before PSM, the LPLN-positive group had higher rates of lower location (53.1% vs. 43.0%, P = 0.025), T4 stage (37.5% vs. 23.2%, P = 0.002), mesorectal fascia (MRF)-positive (53.9% vs. 35.4%, P < 0.001) and extramural venous invasion (EMVI)-positive (51.2% vs. 27.2%, P < 0.001) disease than the LPLN-negative group. After PSM, there were 114 patients for each group along with the balanced clinical factors, and both groups had comparable surgery, pathologic complete response (pCR), and ypN stage rates. The median follow-up was 45.9 months, 3-year OS (88.3% vs. 92.1%, P = 0.276) and LRR (5.7% vs. 2.8%, P = 0.172) rates were comparable between LPLN-positive and LPLN-negative groups. Meanwhile, despite no statistical difference, 3-year PFS (78.8% vs. 85.9%, P = 0.065) and DM (20.4% vs. 13.3%, P = 0.061) rates slightly differed between the groups. 45 patients were diagnosed with DM, 11 (39.3%) LPLN-positive and 3 (17.6%) LPLN-negative patients were diagnosed with oligometastases (P = 0.109)., Conclusions: Our study indicates that for LPLN-positive patients, there is a tendency of worse PFS and DM than LPLN-negative patients, and for this group patients, large samples are needed to further confirm our conclusion., (© 2024.

Opinion Statement: Myxoid liposarcoma (MLS) is a rare subtype of soft tissue sarcoma that distinguishes itself from conventional subtypes through its propensity for extrapulmonary metastasis. The distinctive magnetic resonance imaging (MRI) characteristics of MLS render it an invaluable tool for identifying primary and secondary lesions. Pathologically, MLS is characterized by the FUS-DDIT3 gene fusion. Accurate diagnosis, facilitated by MRI and pathological assessment, is critical for prognostication and the formulation of appropriate treatment strategies. Surgery remains the cornerstone of local management for MLS. The combination of surgery and radiotherapy can significantly reduce the local recurrence rate in MLS, as it is highly sensitive to both radiotherapy and chemotherapy. Additionally, for high-risk MLS cases with a large tumor diameter, chemotherapy has been shown to improve survival. The comprehensive treatment approach for MLS demonstrates superior local recurrence rates and survival rates compared to most soft tissue sarcomas. Current research focuses on developing effective therapies for unresectable or advanced disease based on genomic and phenotypic characteristics as well as the immune-tumor microenvironment., (© 2024.

Objective: We aimed to evaluate the efficacy of decitabine consolidation after treatment with CD19/CD22 chimeric antigen receptor T-cell (CAR-T) for patients with relapsed/refractory B-cell acute lymphoblastic leukaemia (r/r B-ALL)., Methods: We retrospectively analysed 48 patients with r/r B-ALL who received CD19/CD22 CAR-T therapy between September 2017 and May 2021. Sixteen patients received decitabine consolidation (20 mg/m 2 /day for 5 days at 3-month intervals) after CAR-T therapy (DAC group), while 32 patients did not receive decitabine consolidation (CON group). Overall survival (OS), leukaemia-free survival (LFS), and cumulative incidence of relapse (CIR) were evaluated in both groups. Time-to-event analysis was performed using the Kaplan-Meier method., Results: The median follow-up periods in the DAC and CON groups were 41.2 months and 28.6 months, respectively. The 4-year OS and 4-year LFS rates in both groups were 93.3 % and 64.3 % (P=0.029) and 87.5 % and 55.9 % (P=0.059), respectively. The 1-year CIR was 6.25 % and 28.6 %, respectively. Univariate and multivariate Cox regression analyses showed that decitabine consolidation after CAR-T therapy was significantly associated with superior OS (hazard ratio [HR]: 0.121, 95 % confidence interval [CI]: 0.015-0.947, P=0.044), and bridging to haematopoietic stem cell transplantation after CAR-T therapy was significantly associated with superior LFS (HR: 0.279, 95 %CI: 0.093-0.840, P=0.023)., Conclusions: Our study recommends decitabine consolidation after CD19/CD22 CAR-T therapy as a novel maintenance strategy to improve the survival outcomes of patients with r/r B-ALL., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

While outcomes for newly diagnosed children with acute lymphoblastic leukemia (ALL) have improved over the last few decades, 10-15% will relapse. Outcomes for those children with relapse remains a challenge, with 5-year overall survival of approximately 35-60%. Large cooperative group trials have identified factors associated with favorable (low risk, LR) outcome at relapse, including later relapse, B-cell phenotype, isolated extramedullary relapse and a good response to initial re-induction therapy. Contemporary therapeutic regimens are aimed at improving outcomes, while decreasing toxicity. A main focus of current research involves how immunotherapy can be best incorporated with cytotoxic chemotherapy to improve survival in relapsed ALL. Here we review therapeutic strategies for LR relapse, including review of recently completed and ongoing trials.

Background: Patients achieving pathological complete response (pCR) post-neoadjuvant chemoradiotherapy (nCRT) and surgery for locally advanced esophageal squamous cell carcinoma (ESCC) have a favorable prognosis. However, recurrence occurs in approximately 20-30% of all patients, with few studies evaluating their prognostic factors. We identified these prognostic factors, including inflammation-based markers, in patients with ESCC showing pCR after nCRT and surgery., Patients and Methods: Patients with ESCC undergoing esophagectomy post-nCRT (January 2007-August 2017) were studied. Survival analysis evaluated 5-year overall (OS) and recurrence-free survival (RFS). Risk factors, including inflammation factors, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio (PLR), were analyzed using Cox-proportional hazards model., Results: Overall, 123patients participated herein. After a median follow-up duration of 67 months (44-86 months), 17 patients (12.3%) had recurrent disease. The 5-year OS and RFS rates were 71.6% and 68.0%, respectively. In the multivariable analysis, older age ( ≥ 60 years) [hazard ratio (HR) 3.228, 95% confidence interval (CI) 1.478-7.048, p = 0.003], higher pretreatment T stage (≥ T3; HR 2.563, 95% CI 1.335-4.922, p = 0.005), nonapplication of induction chemotherapy (HR 2.389, 95% CI 1.184-4.824, p = 0.015), and higher post-nCRT PLR (≥ 184.2; HR 2.896, 95% CI 1.547-5.420, p = 0.001) were poor independent prognostic factors for 5-year RFS. The patient group with three to four identified factors with poor outcomes exhibited a 5-year RFS rate of 46.2%., Conclusions: Significant prognostic factors include higher post-nCRT PLR, older age, higher clinical T stage, and nonapplication of induction chemotherapy. Identifying higher recurrence risk patients is crucial for tailored follow-up and treatment., (© 2024. Society of Surgical Oncology.)

Locally advanced rectal cancer has traditionally been treated with multimodal therapy including neoadjuvant chemoradiotherapy followed by surgical resection. More recent data suggests that in appropriate patients, total neoadjuvant treatment (TNT) makes it possible to adopt a "watch and wait" approach. Advocates for watch and wait argue that patients with a complete or near-complete clinical response to TNT have comparable overall and disease-free survival to their counterparts who undergo surgical resection, and also have a better quality of life, fewer complications, and potentially avoid a stoma. The dogma of surgery as regional curative intent therapy has been challenged by similar recurrence rates among those treated with total mesorectal excision (TME) and those treated with watch and wait. Furthermore, those who develop local recurrence in the watch and wait groups are equally salvageable, either by surgery, brachytherapy, or chemotherapy. While watch and wait is not appropriate in all patients, this manuscript highlights the benefits and drawbacks of both therapeutic modalities., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: This study aimed to assess the prognostic significance of bulky nodal involvement in patients with anal squamous cell carcinoma treated with definitive chemoradiotherapy., Materials and Methods: We retrospectively analyzed medical records of patients diagnosed with anal squamous cell carcinoma who underwent definitive chemoradiotherapy at three medical centers between 2004 and 2021. Exclusion criteria included distant metastasis at diagnosis, 2D radiotherapy, and salvage treatment for local relapse. Bulky N+ was defined as nodes with a long diameter of 2 cm or greater., Results: A total of 104 patients were included, comprising 51 with N0, 46 with non-bulky N+, and seven with bulky N+. The median follow-up duration was 54.0 months (range, 6.4 to 162.2 months). Estimated 5-year progression-free survival (PFS), loco-regional recurrence-free survival (LRRFS), and overall survival (OS) rates for patients with bulky N+ were 42.9%, 42.9%, and 47.6%, respectively. Bulky N+ was significantly associated with inferior PFS, LRRFS, and OS compared to patients without or with non-bulky N+, even after multivariate analysis. We proposed a new staging system incorporating bulky N+ as N2 category, with estimated 5-year LRRFS, PFS, and OS rates of 81.1%, 80.6%, and 86.2% for stage I, 67.7%, 60.9%, and 93.3% for stage II, and 42.9%, 42.9%, and 47.6% for stage III disease, enhancing the predictability of prognosis., Conclusion: Patients with bulky nodal disease treated with standard chemoradiotherapy experienced poor survival outcomes, indicating the potential necessity for further treatment intensification.

Background Aims: New immunotherapy drugs, such as bispecific T-cell engager antibodies, checkpoint inhibitors and antibody-drug conjugates, are commonly used as salvage therapy for patients with non-Hodgkin lymphoma relapsing after chimeric antigen receptor (CAR) T-cell therapy. Nevertheless, their potential long-term effects on the outcome of allogeneic stem cell transplantation (Allo-SCT) are not well known., Methods: We retrospectively analyzed the outcomes of 27 relapsed/refractory non-Hodgkin lymphoma patients receiving Allo-SCT after immunotherapy in the pre-CAR T-cell therapy era and compared them with a historical cohort of 28 subjects undergoing Allo-SCT after conventional therapy., Results: The two cohorts had similar outcomes in terms of graft-versus-host disease/relapse-free survival (4 years, 59% versus 46%), overall survival (4 years, 77% versus 44%), non-relapse mortality (4 years, 19% versus 22%) and acute (6 months, 15% versus 21%) and chronic (4 years, 18% versus 24%) graft-versus-host disease. Of note, the cumulative incidence of relapse was lower after immunotherapy (4 years, 4% versus 14%), although significance was not reached. The cumulative incidence of cytomegalovirus and fungal infection did not differ among the two cohorts., Conclusions: Consolidation with Allo-SCT is a safe and curative option for patients achieving disease response after new immunotherapy drugs that could represent a desirable salvage strategy for patients relapsing after CAR T-cell therapy., Competing Interests: Declaration of Competing Interest The authors have no commercial, proprietary or financial interest in the products or companies described in this article., (Copyright © 2024 International Society for Cell & Gene Therapy.

Sinonasal mucosal melanoma (SNMM) is a rare malignancy with poor prognosis and high recurrence rate. In those with recurrence, survival is dismal. Immunotherapy is an emerging area of investigation; however, there is a scarcity of data on immunotherapy outcomes in SNMM patients with recurrence. We report outcomes of immunotherapy in recurrent SNMM patients with distant versus nondistant recurrence. Fifty-four patients with recurrent SNMM were identified, and 31 (57.4%) had distant recurrence. One-year overall survival (OS) following recurrence was 47.5% (95% confidence interval [CI]: 34.0%-60.9%), with a median survival of 2.8 years (95% CI: 2.0-5.3). In those with distant recurrence, receipt of immunotherapy was associated with better OS compared to those without immunotherapy (hazard ratio [HR] = 0.29 [95% CI: 0.12-0.68], P = .004). While patients with nondistant recurrence (n = 23), who received immunotherapy (n = 6) had worse OS compared to those who did not receive immunotherapy (HR = 4.76 [95% CI: 1.36, 15.89], P = .02).

Background: The standard of care for the treatment of locally advanced rectal cancer (LARC) results in an excellent local disease control but the metastasis rates remain high. PRODIGE 23 demonstrated improved disease-free survival (DFS) and metastasis-free survival (MFS) with total neoadjuvant therapy versus standard of care in this population. Long-term analysis of overall survival (OS) is reported here., Patients and Methods: The study design, participants, and primary endpoint DFS have been reported for this multicenter, randomized, open-label, phase III trial investigating the neoadjuvant chemotherapy with mFOLFIRINOX (6 cycles) followed by chemoradiotherapy, surgery, and adjuvant chemotherapy (6 cycles), versus chemoradiotherapy, surgery, and adjuvant chemotherapy (12 cycles) in patients with locally advanced rectal adenocarcinoma under peritoneal reflection on magnetic resonance imaging, and staged cT3/T4. Key secondary endpoints included OS, MFS, and local and metastatic recurrence rate., Results: With a median follow-up of 82.2 months, the 7-year DFS was 67.6% [95% confidence interval (CI) 60.7% to 73.9%] and 62.5% (95% CI 55.6% to 68.6%) [restricted mean survival time (RMST) difference 5.73 months, 95% CI 0.05-11.41 months, P = 0.048] in the neoadjuvant chemotherapy and the standard-of-care groups, respectively. The 7-year MFS was 79.2% (95% CI 73.0% to 84.4%) in the neoadjuvant chemotherapy group and 72.3% (95% CI 65.8% to 77.8%) in the standard-of-care group (RMST difference 6.1 months, 95% CI 0.93-11.37 months, P = 0.021). The 7-year OS was 81.9% (95% CI 75.8% to 86.6%) in the neoadjuvant chemotherapy group and 76.1% (95% CI 69.7% to 81.2%) in the standard-of-care group (RMST difference 4.37 months, 95% CI 0.35-8.38 months, P = 0.033). The safety profile remained unchanged since the previous analysis., Conclusions: Neoadjuvant chemotherapy with mFOLFIRINOX followed by chemoradiotherapy improved OS, confirmed long-term DFS and MFS benefits in LARC patients, and should be considered as one of the best options of care for these patients., (Copyright © 2024 European Society for Medical Oncology.

Background: Clinical T4 (cT4) stage gastric cancer presents with frequent postoperative recurrence and poor prognosis. This study is to evaluate the oncological efficacy of laparoscopic radical total gastrectomy combined with postoperative prophylactic hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with cT4N + M0 gastric cancer who received neoadjuvant chemotherapy., Methods: We reviewed the clinicopathological data of 174 patients with clinical T4 gastric cancer who underwent neoadjuvant chemotherapy followed by laparoscopic radical total gastrectomy between June 2017 and December 2021. Among them, 142 were included in the non-HIPEC group, and 32 in the HIPEC group. Patients in both groups were paired based on propensity score in a 2:1 ratio to assess disparities in tumor recurrence and long-term survival., Results: After matching, there were no significant differences in the clinicopathological data between the two groups. The peritoneum (16.1%) and distant organs (10.9%) were the most frequent locations for recurrence. Prior to matching, the recurrence rates were similar at all sites for both groups. Compared with those in the non-HIPEC cohort, the recurrence rates at all sites, the lung, and the peritoneum were notably lower in the HIPEC cohort. Prior to matching, the 3-year overall survival and disease-free survival rates were similar between the two groups; following matching, the HIPEC group exhibited notably greater survival rates than did the non-HIPEC group. The disparities in survival rates between the groups became even more pronounced after conducting a stratified analysis among patients with stage III disease., Conclusions: Neoadjuvant chemotherapy combined with prophylactic HIPEC after laparoscopic radical gastrectomy can effectively reduce the rate of peritoneal metastasis in patients with cT4N + M0 advanced gastric cancer and significantly improve the prognosis of such patients, which is of great clinical value., (© 2024.

Despite low incidence, neuroblastoma, an immunologically cold tumor, is the most common extracranial solid neoplasm in pediatrics. In relapsed/refractory cases, the benefits of autologous hematopoietic stem cell transplantation (auto-HSCT) and other therapies are limited. Natural killer (NK) cells apply cytotoxicity against tumor cells independently of antigen-presenting cells and the adaptive immune system. The primary endpoint of this trial was to assess the safety of the injection of allogenic, ex vivo-expanded and primed NK cells in relapsed/refractory neuroblastoma patients after auto-HSCT. The secondary endpoint included the efficacy of this intervention in controlling tumors. NK cells were isolated and primed ex vivo (by adding interleukin [IL]-2, IL-15, and IL-21) in a GMP-compliant CliniMACS system and administered to four patients with relapsed/refractory MYCN-positive neuroblastoma. NK cell injections (1 and 5 × 10 7 cells/kg in the first and second injections, respectively) were safe, and no acute or sub-acute adverse events were observed. During the follow-up period, one complete response (CR) and one partial response (PR) were observed, while two cases exhibited progressive disease (PD). In follow-up evaluations, two died due to disease progression, including the case with a PR. The patient with CR had regular growth at the 31-month follow-up, and another patient with PD is still alive and receiving chemotherapies 20 months after therapy. This therapy is an appealing and feasible approach for managing refractory neuroblastomas post-HSCT. Further studies are needed to explore its efficacy with higher doses and more frequent administrations for high-risk neuroblastomas and other immunologically cold tumors.Trial registration number: irct.behdasht.gov.ir (Iranian Registry of Clinical Trials, No. IRCT20201202049568N1)., (© 2024.

Background: Adjuvant nivolumab reduces recurrence in patients with locoregional esophageal cancer who had pathological residual disease after neoadjuvant chemoradiotherapy and R0 resection. However, the efficacy of adjuvant anti-PD-1 therapy in patients at higher risk of recurrence remains unclear., Methods: This phase II trial (ClinicalTrials.gov identifier: NCT03322267) enrolled patients with locally advanced esophageal squamous cell carcinoma (ESCC) received neoadjuvant chemoradiotherapy plus esophagectomy but still had various risk factors for recurrence, such as involved or close margins (≤ 1 mm), extranodal extension of the involved lymph nodes, and the ypN2-3 stage. Patients received adjuvant therapy composed of a course of cisplatin-based chemoradiotherapy and pembrolizumab (200 mg, IV every 3 weeks) for 18 cycles. The primary endpoint was 1-year relapse-free survival (RFS) rate., Results: Twenty-five patients were enrolled. The risk factors were tumor margins of ≤ 1 mm (18 patients), extranodal extension of the involved lymph nodes (9 patients), and the ypN2-3 stage (9 patients). The median follow-up duration was 21.6 months (95% CI: 18.7-33.2). The rate of 1-year RFS was 60.0%. The median duration of RFS and overall survival was 14.3 (95% CI: 9.0-19.5) and 21.6 (95% CI: 0.0-45.5) months, respectively. Treatment-emergent adverse events of any grade and those of ≥ 3 grade occurred in 56% and 8% of all patients receiving cisplatin-based chemoradiotherapy and in 79.2% and 12.5% of those receiving pembrolizumab., Conclusions: Adjuvant chemoradiotherapy followed by pembrolizumab is feasible and may be associated with improved 1-year RFS rate in patients at high risk of recurrence after trimodality therapy for locally advanced ESCC.

Background: Chimeric antigen receptor (CAR) T-cell therapy (CAR-T therapy) has demonstrated significant efficacy in the ZUMA-2 study. After regulatory approvals, several clinical trials and real-world studies on CAR-T therapy for relapsed or refractory mantle cell lymphoma (R/R MCL) were conducted. However, data on clinical safety and efficacy are inconsistent. In this study, we aimed to conduct a systematic analysis of the effectiveness and safety of CAR-T therapy across a wider and more representative cohort of patients with R/R MCL., Methods: We performed a systematic review and meta-analysis of studies on patients with R/R MCL who received CAR-T cell therapy. Data were extracted and consolidated, with primary focus on the evaluation of safety and efficacy outcome measures. This study has not been registered with PROSPERO., Results: This meta-analysis identified and included 16 studies with 984 patients. The pooled estimate for overall response rate (ORR) was 89%; complete remission (CR) rate was 74%. The 6-month and 12-month progression-free survival (PFS) rates were 69% and 53%, respectively, while the overall survival (OS) rates were 80% and 69%, respectively. Cytokine release syndrome (CRS) of grade 3 or higher was observed in 8% of patients, whereas neurotoxicity of grade 3 or higher was observed in 22% of patients. The risk of bias was assessed as low in 9 studies and moderate in 7 studies., Conclusion: CAR-T therapy exhibited promising efficacy and manageable adverse reactions in patients with R/R MCL., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Wan, Weng, Sheng, Kuang, Wang and Hu.)

Purpose: This study aimed to report the 5-year clinical outcomes of anti-B-cell maturation antigen chimeric antigen receptor (CAR) T-cell (HDS269B) therapy in patients with relapsed/refractory multiple myeloma (RRMM), including those with poor performance status [Eastern Cooperative Oncology Group (ECOG) scores 3 to 4], and to identify factors influencing long-term outcomes., Patients and Methods: Forty-nine patients with RRMM enrolled from 2016 to 2020 received HDS269B (9 × 106 cells/kg) after receiving a conditioning chemotherapy consisting of cyclophosphamide and fludarabine. The overall response, long-term outcomes, and safety were assessed, as were their associations with clinical and disease characteristics., Results: With a median follow-up of 59.0 months, the overall response rate was 77.55%. The median progression-free survival (PFS) and overall survival (OS) were 9.5 months [95% confidence interval (CI), 5.01-13.99] and 20.0 months (95% CI, 11.26-28.74), respectively. The 5-year PFS and OS rates were 21.3% (95% CI, 12.3%-36.7%) and 34.1% (95% CI, 22.7%-51.3%), respectively. Patients with ECOG 0 to 2 had marked longer survival, with a median PFS of 11.0 months and a median OS of 41.8 months. Early minimal residual disease negativity, higher and persistent CAR T-cell expansion, and the absence of extramedullary disease were associated with better survival outcomes. No new CAR T-cell therapy-associated toxicities were observed. Importantly, ECOG scores 0 to 2, prior therapy lines <4, and CAR T-cell persistence at ≥6 months were independently associated with longer OS., Conclusions: HDS269B is effective and safe, especially for patients with ECOG scores 0 to 2. Early CAR T-cell intervention may improve prognosis in patients with RRMM., (©2024 The Authors; Published by the American Association for Cancer Research.)

Objective: The aim of this study was to investigate the impact of adjuvant treatments, factors influencing recurrence, and survival data in patients with 2023 International Federation of Gynecology and Obstetrics (FIGO) stage IIB endometrial cancer., Methods: A retrospective analysis was conducted on patients with endometrial cancer who underwent surgery between 2005 and 2022 at seven different centers in Turkey. Demographic, clinicopathological, and survival data were collected and analyzed., Results: Among 7323 patients, 565 (7.7%) were classified as 2023 FIGO stage IIB based on pathological results. Of 565 patients, 214 were followed without receiving adjuvant treatment, while 335 (95.4%) received adjuvant radiotherapy, and 16 (4.6%) received radiotherapy and chemotherapy. The locoregional recurrence rate was higher in patients with a tumor size >4 cm (p=0.038) and myometrial invasion >50% (p=0.045). In patients with distant metastasis, the recurrence rate was lower in those with myometrial invasion <50% compared with myometrial invasion ≥50% (p=0.031). The impact of adjuvant treatment on endometrial cancer patients revealed no significant differences for both disease free survival (p=0.85) and overall survival (p=0.54). Subgroup analyses showed that in patients with deep myometrial invasion, adjuvant treatment was associated with a significant increase in overall survival (p=0.044), but there was no effect on disease-free survival (p=0.12)., Conclusions: Patients with stage IIB endometrial cancer with myometrial invasion ≥50% were more likely to have locoregional and distant metastases.

The WHO (World Health Organization) conducted an elimination of cervical cancer program using triple pillar intervention strategy to target 90%-70%-90% of women before the year 2030, including (1) a full vaccination of HPV (human papillomavirus) vaccine to 90% of girls <15 years of age; (2) a high-performance screening procedure to 70% of women during the reproductive age (at the age of 35 and 45 years of age); and (3) an appropriate and adequate treatment to 90% of women with confirmed diagnosis of cervical lesions. Among the aforementioned three pillars, a full HPV vaccination has been introduced in our previous review, of which we have discussed the policy and strategy of HPV vaccination in the world and also reviewed the efficacy of HPV vaccination, with a successful reduction of over 90% of HPV-associated neoplasms. The aims of the current review will target another pillar-an appropriate and adequate treatment to 90% of women with confirmed diagnosis of cervical lesions. Since the early-stage cervical cancer has a favorable outcome and the treatment recommendation has been established, therefore, the current review focuses on women with persistent, recurrent and metastatic cervical cancers (advanced cervical cancers), which are still a biggest challenge based on its extremely worse outcomes before the introduction of immune checkpoint inhibitors (ICIs). Integration of ICIs into conventional chemotherapy (paclitaxel-cisplatin) has become the new standard therapy for those patients with advanced cervical cancers. The recent clinical trials, such as KENOTE 826 and KENOTE A18 showing a dramatical improvement of both progression free survival and overall survival have approved the therapeutic efficacy of this combination as ICI plus paclitaxel-platinum (cisplatin or carboplatin) with/without bevacizumab to women with persistent, recurrent and metastatic cervical cancers., Competing Interests: Declaration of competing interest Dr. Peng-Hui Wang and Dr. Szu-Ting Yang, editorial board members at Taiwanese Journal of Obstetrics and Gynecology, had no role in the peer review process of or decision to publish this article.

Background/aim: Near-infrared photoimmunotherapy (NIR-PIT) is a recently developed cancer treatment modality that selectively kills cancer cells and may induce a therapeutic host immune response. The aim of this study was to determine the feasibility of combining NIR-PIT with immune checkpoint inhibitor (ICI) therapy for unresectable recurrent head and neck cancer., Patients and Methods: Five patients underwent NIR-PIT at Ryukyu University Hospital between January 2022 and April 2024. These patients had unresectable recurrent head and neck squamous cell carcinoma. Among these five patients, four received a combination NIR-PIT and pembrolizumab administration., Results: A total of seven lesions in the oropharynx and oral cavity were targeted. One patient was treated for three different target lesions. The best observed response (BOR) rate was 100%, with three complete responses and four partial responses. The most common treatment-related adverse event was Grade 1 or 2 local pain lasting one to two days postoperatively, which occurred in all patients. Grade 3 adverse events occurred in three cases (42.9%), including pneumonia, pharynx-cutaneous fistula, and trismus. Three patients received ICI therapy following NIR-PIT, achieving a 60% BOR rate. No immune-related adverse events were noted, and the aforementioned Grade 3 adverse events did not worsen during ICI therapy. At a median follow-up of 376 days (range=157-845 days), four target lesions showed no recurrence, while three had recurred. All five patients were alive, including three with no evidence of disease., Conclusion: The combination of NIR-PIT and ICI therapy for unresectable recurrent head and neck cancer was feasible., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.

Background/aim: The study aimed to investigate the efficacy of radiotherapy or chemoradiotherapy for isolated locoregional recurrence after pancreatectomy for pancreatic cancer., Patients and Methods: Twenty-eight patients who had isolated locoregional recurrence after pancreatectomy for pancreatic cancer between 2007 and 2021 were retrospectively analyzed. We investigated the effect of the treatment method [radiotherapy or chemoradiotherapy (radiotherapy with concurrent chemotherapy)] on progression-free survival (PFS) and post-recurrence survival (PRS)., Results: The median disease-free survival was 16.1 months (range=4.7-47.1 months). Five patients received radiotherapy and 21 patients received chemoradiotherapy [radiotherapy concurrent with gemcitabine (GEM) or S-1] for locoregional recurrence. All patients except one patient with interstitial pneumonia were treated with salvage chemotherapy after irradiation. The median PFS rates of the radiotherapy group and the chemoradiotherapy group were 2.8 months (range=1.5-5.4 months) and 16.8 months (range=2.7-42.8 months), respectively. The median PRS rates were 23.7 months (range=8.1-26.4 months) for the radiotherapy group and 26.2 months (range=6.0-64.7 months) for the chemoradiotherapy group. Multivariate analysis identified radiotherapy [hazard ratio (HR)=12.2, 95% confidence interval (CI)=3.29-45.6, p<0.001] and serum DUPAN-2 >150 U/ml (HR=2.90, 95%CI=1.22-6.93, p=0.02) as independent predictors of PFS, and UICC TNM Stage ≥III (HR=3.23, 95%CI=1.17-8.96, p=0.02) and modified Glasgow prognostic score before the treatment for the recurrence 1 or 2 (HR=3.05, 95%CI=1.15-8.08, p=0.03) as independent predictors of PRS., Conclusion: Chemoradiotherapy for isolated locoregional recurrence after pancreatectomy for pancreatic cancer could suppress re-recurrence more effectively than radiotherapy., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.

Introduction: Total neoadjuvant therapy (TNT) in the management of locally advanced rectal cancer (LARC) did not show survival benefit over the standard long course chemoradiotherapy. Trials of TNT did not address the impact of each risk feature in isolation from other high-risk features., Methodology: In this retrospective study, we describe the clinical outcomes of patients with T4 and/or N2 rectal adenocarcinoma who were treated with chemoradiotherapy followed by total mesorectal excision (TME). After obtaining the local regulatory approvals, demographic and clinical data were collected for patients in Manitoba between January 2007 and December 2019., Results: The cohort included 331 patients. 61 patients had T4-only disease and 218 had N2-only disease. Mean age was 59.65 years. 74.3% received adjuvant chemotherapy (ACT), but only 56.5% completed the planned course. R0 resection was achieved in 93.4% of patients (78.7% and 97.2% in T4 and N2, respectively). Median follow up was 4.93 years. 3-year overall recurrence rate was 29%. 3-year locoregional recurrence (LRR) rate was 8% (16% and 6% in T4 and N2, respectively). 3-year overall survival (OS) rate was 84% in the whole cohort (72.6% and 87.1% in T4 and N2, respectively). Incomplete surgical resection was a poor prognostic factor for both OS and LRR. ACT was associated with a survival benefit in the whole cohort (P = .001) and in the N2 sub-cohort (P = 003) but there was no survival benefit observed in T4 sub-cohort. ACT did not have an impact on LRR., Conclusions: Achieving R0 resection in LARC with neoadjuvant therapy improves recurrence and survival rates. T4 disease carries a worse clinical outcome than N2 and consideration should be given to upstage T4 to stage III. Different high-risk features in LARC predict different clinical outcomes. In the era of TNT, personalization of treatment strategy based on these factors could potentially improve outcomes., Competing Interests: Disclosure The authors have stated that they have no conflicts of interest., (Copyright © 2024 Elsevier Inc.

Background: Locally infiltrating (T4) differentiated thyroid carcinomas (DTC) represent a challenge. Surgical strategy and adjuvant therapy should be planned balancing morbidity and oncologic outcome. A series of patients with T4 DTC who underwent multidisciplinary evaluation and treatment is reported. The main study endpoints were the oncologic outcome, complication rates, and risk factors for tumor recurrence., Patients and Methods: All DTC cases operated between 2009 and 2021 were reviewed and T4 DTC cases were identified. En bloc resection of inferior laryngeal nerve (ILN), tracheal, and/or internal jugular vein (IJV) was performed in cases of massive infiltration. In cases of pharyngoesophageal junction (PEJ) invasion, the shaving technique was always applied., Results: Among 4775 DTC cases, 60 were T4. ILN infiltration was documented in 45 cases (en bloc resection in 9), tracheal infiltration in 14 (tracheal resection in 2), PEJ invasion in 11 (R0 resection in 7 cases and < 1 cm residual tissue in 4 cases), IJV resection in 6, and laryngeal in 2. In total, 11 postoperative ILN palsy, 23 transient hypoparathyroidisms, and 2 hematomas requiring reoperation were registered. Final histology showed 7 pN0, 22 pN1a, and 31 pN1b tumors. Aggressive variants were observed in 47 patients. All but 1 patient underwent radioiodine treatment, 12 underwent adjuvant external beam radiation therapy (EBRT), and 2 underwent chemotherapy. At a median follow-up of 58 months, no tumor-related death was registered, and seven patients required reoperation for recurrence. Tracheal invasion was the only significant factor negatively impacting recurrence (p = 0.045)., Conclusions: A multidisciplinary approach is essential for the management of T4 DTC. Individualized and balanced surgical strategy and adjuvant treatments, in particular EBRT, ensure control of locally advanced disease with acceptable morbidity., (© 2024. The Author(s).)

Objective: Globally, head & neck sarcoma care pathways remain unclear. In 2018, the London Sarcoma Service (LSS) set up a dedicated head and neck sarcoma (HNS) multidisciplinary team (MDT) with a clear objective to provide formal access to super-specialist expertise in diagnosis, treatment planning and management of HNS. The aim of the study is to provide first results of a dedicated HNS MDT., Methods: All patients discussed between 2018 and 2022, in HNS MDT, with a new histologically confirmed HNS diagnosis were included in the study. Demographics, anatomic site, morphology, MDT recommendation, treatment details and outcomes were obtained from electronic patient records., Results: A total of 337 patients were discussed in the HNS MDT of which 178 patients were included in the study, with a median age of 53 years(range 2-94); 67 % were soft tissue sarcomas(STS) and 33 % were bone sarcomas(BS), of which 43 % and 71 % were high grade, respectively. 55 % BS and 39 % STS underwent surgery. 9 % of BS and 7 % of STS received adjuvant Proton Beam therapy. With a median follow-up of 2.16 years, recurrence was observed in 12 %, distant metastasis in 6 % of patients and overall survival was 72 %., Conclusion: The HNS MDT provides expertise on diagnosis and multi-modality management of HNS. STS are more likely to be misdiagnosed. Atypical imaging characteristics should trigger a specialist referral. Adequate surgery at first presentation remains the mainstay of treatment and the strongest prognosticator of overall survival. Formation of an expert working group specific to HNS must work towards streamlining sarcoma care., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Purpose: This study was designed to characterize features of rapid relapse TNBC (rrTNBC), an aggressive, poor prognosis breast cancer subset using the National Cancer Database (NCDB)., Methods: Patients diagnosed with TNBC between 2010 and 2019 within NCDB were included in analyses. rrTNBC was defined as all-cause mortality ≤24 months from diagnosis. Patient demographic, tumor, and treatment association with rrTNBC were evaluated in univariate, bivariate analyses, and multiple logistic regression models. Two-part models are used to compare receipt of treatment (i.e., receipt of both chemotherapy and breast surgery) versus not in its relationship with rrTNBC., Results: Overall, 14.5% of patients were categorized as rrTNBC. Age older than 75 years (-41.3%), Black race (-1.4%), Medicare (-2.6%), and Charlson-Deyo score ≥2 (-4.9%) were associated with a lower probability of receiving both chemotherapy and breast surgery. Not receiving both treatments (vs. receiving both chemotherapy and breast surgery) was associated with a two-to-three-fold higher probability of rrTNBC among patients aged older than 75 years (16.6% vs. 6%), having Medicare (3.6% vs. 1.6%), and Charlson-Deyo score ≥2 (16.6% vs. 5.9%)., Conclusions: Age, insurance, and comorbidity were related to a lower likelihood of treatment; yet receiving treatment reduced the risk of rrTNBC threefold for each. These findings might be valuable to inform clinical care delivery, as well as future research that examines treatment protocols among diverse patients., (© 2024. The Author(s).)

Background: This study investigated predictive factors for patients with peritoneal metastases of gastric cancer (PMGC) who underwent conversion cytoreductive surgery (C-CRS) and hyperthermic intraperitoneal intraoperative chemotherapy (HIPEC) after responding to induction chemotherapy (laparoscopic HIPEC [LHIPEC]) followed by concomitant systemic and intraperitoneal chemotherapy (bidirectional intraperitoneal and systemic chemotherapy [BIC])., Methods: Diagnostic laparoscopy was performed for 62 patients with PMGC between January 2017 and December 2022. The patients underwent LHIPEC and BIC induction chemotherapy using intraperitoneal docetaxel (30 mg/m 2 ) and cisplatin (30 mg/m 2 ), and intravenous chemotherapy for three cycles. The predictive parameters for progression-free and overall survival were analyzed using Kaplan-Meier and Cox regression analyses. The optimal cutoff values for Ki-67 parameters were assessed using receiver operating characteristic curve analysis., Results: The study retrospectively examined 36 (58 %) of 62 patients who responded to induction therapy and underwent C-CRS or HIPEC. A Ki-67 index lower than 10 (p = 0.000), lymph node involvement (LNI) less than 2 (p = 0.039), and an omental lesion size score lower than 0.5 cm (p = 0.002) were predictive of recurrence-free and overall survival in addition to completeness of cytoreduction and the peritoneal cancer index. Cox regression analysis showed that the independent factors associated with recurrence-free survival were decreased Ki-67 expression (≥10 % vs <10 %) (hazard ratio [HR] 4.7; 95 % confidence interval [CI] 1.6-5.210; p = 0.020) and LNI higher than 2 (HR 1.92; 95% CIS 0.923-4.0; p = 0.023)., Conclusions: Lymph node involvement and decreased Ki-67 expression are independent predictive factors of recurrence-free survival for patients with PMGC after induction chemotherapy., (© 2024.

Introduction: Stage IV colorectal cancer is a highly challenging condition to treat, with 5-year survival rates of 13% in Australia, improving to 40% for those patients with locally recurrent rectal cancer who are suitable for total neoadjuvant therapy and pelvic exenterative surgery. This study reports a unique case of a patient with Stage IV locally recurrent rectal cancer (LRRC), who designed and implemented a holistic integrative oncology intervention., Case Presentation: The patient was 59-years-old when diagnosed with Stage IV locally recurrent rectal cancer, and referred to a highly specialised centre for colorectal cancer care at a tertiary teaching hospital in Sydney, Australia. Treatment included chemo/radiotherapy, liver resection and posterior pelvic exenteration surgery. The patient's background as a health researcher and clinician optimised her ability to design and implement an integrative oncology model of care, including yoga, mindfulness, Buddhist meditation and study, social connection, exercise, psychotherapeutic and nutritional support. This paper describes these mind-body practices and lifestyle modifications and outlines her experiences and outcomes at each stage of her extensive and radical treatment., Conclusion: This case provides a unique perspective into how the integration of mind-body practices and lifestyle modifications with conventional treatment can support those living with colorectal cancer., (Copyright © 2024 The Author(s).

Treatment of relapsed and refractory myeloid leukemia in Down syndrome (r/r ML-DS) poses significant challenges, as prognosis is dire and there is no established standard treatment. This guideline provides treatment recommendations based on a literature review and collection of expert opinions, aiming to improve overall and event-free survival of patients. Treatment options include fludarabine and cytarabine (FLA) ± gemtuzumab ozogamicin (GO), azacytidine (AZA) ± panobinostat, and hematopoietic stem cell transplantation (HSCT). Preferred approaches are AZA ± panobinostat for cases with low blast count or FLA ± GO for cases with high blast count, followed by HSCT after remission. Further research is crucial for the investigation of targeted therapies (e.g., BH3 mimetics, LSD1, JAK inhibitors)., (© 2024 The Author(s).

Purpose: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are expected to be synergistic with intraperitoneal (IP) immunotherapy by increasing tumor antigen expression and mutational load. We assessed the feasibility and safety of IP nivolumab following complete CRS and HIPEC in pretreated patients with recurrent ovarian cancer (ClinicalTrials.gov identifier: NCT03959761)., Patients and Methods: Patients received IP nivolumab (0.5, 1, or 3 mg/kg) using a 3 + 3 dose-escalation design, starting 5 to 7 days after CRS and HIPEC. Four IP Q2W (once every 2 weeks) nivolumab infusions were planned. The primary objective was to demonstrate the feasibility of IP nivolumab based on dose-limiting toxicity. Secondary objectives were to assess changes in tolerance of CRS and HIPEC., Results: A total of 17 patients were enrolled including 10 patients in the dose escalation and 7 patients in the expansion phase. No dose-limiting toxicity was observed at any dose level in the 9 evaluable patients. Six of the 17 patients (35%) did not complete all planned infusions: 4 (23.5%) due to peritoneal catheter complications and 2 (11.8%) due to early progression. No procedure-related deaths occurred. Eleven patients (65%) experienced serious adverse events (SAE), mainly transitory grade 3 to 4 transaminase elevations (6/11) and surgery-related (9/11). Four SAEs were related to the peritoneal catheter and two to HIPEC. No SAEs/grade 3 to 4 adverse events related to IP nivolumab occurred., Conclusions: This is the first study demonstrating the feasibility of IP nivolumab in patients with relapsed advanced ovarian cancer. Further investigation at 3 mg/kg is warranted., (©2024 American Association for Cancer Research.)

Introduction: Large B-cell lymphomas (LBCL) are the most frequently aggressive B-cell non-Hodgkin lymphomas. Anti-CD19 chimeric antigen receptor (CAR)-T cell therapy has emerged as a new, powerful treatment for relapsed or refractory (R/R) disease. Two CAR-T cell products, tisagenlecleucel (tisa-cel,) and axicabtagene ciloleucel (axi-cel), are reimbursed in Belgium for R/R LBCL beyond second line., Objectives and Methods: We conducted a retrospective cohort study to report the outcome with tisa-cel and axi-cel for R/R LBCL beyond second line in the years 2019-2023 at the University Hospitals Leuven for 79 patients selected for apheresis and CAR-T infusion., Results: Eleven patients (14%) did not proceed to CAR-T cell infusion. For infused patients ( n  = 68), the best overall response rate (ORR)/complete response (CR) rate was 64%/49% for tisa-cel and 88%/66% for axi-cel ( p  = 0.04 for ORR). After a median follow-up of 13.8 months, progression-free survival (PFS) and overall survival (OS) at 1 year were 30% and 43% for tisa-cel and 48% and 62% for axi-cel. Cytokine release syndrome (CRS) (all grades/grade ≥3) occurred in 82%/9% after tisa-cel and in 97%/0% after axi-cel. Immune effector cell-associated neurotoxicity syndrome (ICANS) (all grades/grade ≥3) occurred in 24%/18% after tisa-cel and in 54%/40% after axi-cel. The non-relapse mortality in the infusion cohort was 13%., Conclusion: Our real-world data show high and durable response rates, with a non-significant trend towards a higher efficacy and higher toxicity for axi-cel compared to tisa-cel. Our results are in line with other real-world registries except for a shorter median OS and more high-grade ICANS.

Pancreatic acinar cell carcinoma (PACC) is a rare cancer with no specific treatment. The treatment and chemotherapy for PACC are selected according to pancreatic ductal adenocarcinoma (PDAC). Herein, we describe a recurrent PACC case of an older adult patient. The patient was treated with systemic chemotherapy, chemoradiotherapy, and maintenance therapy based on the pathologic germline BRCA2 variant, resulting in long-term survival. The pathogenic BRCA variant is detected more frequently in patients with PACC than in those with PDAC. The BRCA variant significantly impacts treatment selection and prognosis; therefore, early genomic analysis is recommended when treating PACC., (© 2024. Japanese Society of Gastroenterology.)

Undifferentiated embryonal sarcoma of the liver (UESL) is an extremely rare and aggressive malignancy in adults. 1 Adults with UESL have a worse prognosis compared to pediatric population. 2 Due to the rarity of this disease in adults, there has been a lack of information that assists in treatment decisions within this group. Improved understanding of UESL in adults might assist in understanding biological differences compared to pediatric cohorts as well as tailor treatments to improve their overall outcome. We described the management and outcome of a young adult managed at our center with metastatic relapsed UESL. For comparison, a PubMed search for adolescent and young adult (AYA) and adults with UESL was performed with the aim to review and address any distinct clinical features, different aspects of management and survival outcomes within this population. A 21-year-old male underwent right hepatectomy for a large 16 cm localized UESL with clear surgical margin and did not receive adjuvant chemotherapy. Seven months postsurgery, he relapsed with both local and metastatic disease and underwent chemotherapy with vincristine, doxorubicin, cyclophosphamide alternating with ifosfamide and etoposide achieving a complete metabolic response. This was followed by Stereotactic Ablative Radiation Therapy and surgical resection of residual disease. He remains free of disease 3 years since his diagnosis. We subsequently reviewed 42 AYA and adults (aged >15) with UESL (median age, 33 years) between 1991 and 2022. Most patients presented with localized UESL and for those treated with surgery alone, 67% developed recurrences. Those receiving multimodality treatment, better outcomes, and reduced relapse rate was achieved. Twenty-seven patients developed recurrences, 13 with local recurrences and 14 with metastatic relapse. The median time to relapse was 12 months. We reported a successful outcome in multimodality treatment which resulted in long remission in a young adult with relapsed UESL. Combination of perioperative chemotherapy with locoregional treatment is important to improve long-term survival in adults with metastatic UESL.

Background: The higher pathologic complete response (pCR) after neoadjuvant chemoradiotherapy compared with neoadjuvant chemotherapy for locally advanced esophageal squamous cell carcinoma (ESCC) has not translated into significant gains in overall survival. Data on the long-term survival of patients who obtained a pCR after neoadjuvant chemotherapy are scarce. Therefore, this study aimed to evaluate the long-term prognosis and recurrence patterns in these patients., Methods: The study enrolled patients with locally advanced ESCC after neoadjuvant chemotherapy followed by surgery in the authors' hospital between January 2007 and December 2020. The factors predictive of pCR were analyzed. Furthermore, propensity score-matching was performed for those who did and those who did not have a pCR using 1:5 ratio for a long-term survival analysis. Finally, the survival and recurrence patterns of patients obtaining pCR after neoadjuvant chemotherapy were analyzed., Results: A pCR was achieved for 61 (8.70%) of the 701 patients in the study. Univariate analysis showed that the patients without alcohol drinking had a higher possibility of obtaining a pCR, although multivariate analysis failed to confirm the difference as significant. After propensity score-matching, the 5-year overall survival was 84.50% for the patients who had a pCR and 52.90% for those who did not (p < 0.001). Among the 61 patients with a pCR, 9 patients (14.80%) experienced recurrence, including 6 patients with locoregional recurrence and 3 patients with distant metastasis., Conclusion: Advanced ESCC patients with pCR after neoadjuvant chemotherapy had a favorable prognosis, yet some still experienced recurrence, particularly locoregional recurrence. Therefore, for this group of patients, regular follow-up evaluation also is needed., (© 2024. Society of Surgical Oncology.)

The addition of rituximab to standard regimens for primary mediastinal large B-cell lymphoma (PMBCL) has significantly improved overall survival. However, the optimal management of isolated central nervous system (CNS) relapse and role of CNS prophylaxis remains undefined. We present cases of two adolescents with PMBCL who developed isolated CNS relapses. While isolated CNS relapse may be managed with high-dose chemotherapy and autologous stem cell transplant with or without CNS radiotherapy, review of these cases and the literature highlight the need for further work to define risk factors for CNS relapse, and identify patients who may benefit from CNS prophylaxis., (© 2024 Wiley Periodicals LLC.)

Autologous hematopoietic cell transplantation (AHCT) is often used as a consolidation for patients with peripheral T-cell lymphomas (PTCLs) due to the poor prognosis associated with this heterogenous group of disorders. However, a significant number of patients will experience post-AHCT disease relapse. Here, we report a retrospective study of consecutive 124 patients with PTCLs who underwent AHCT from 2008 to 2020. With a median follow-up of 6.01 years following AHCT, 49 patients (40%) experienced disease relapse. As expected, more patients who were not in first complete remission experienced post-AHCT relapse. Following relapse, majority of the patients (70%) receiving systemic therapies intended as bridging to curative allogeneic HCT. However, only 18 (53%) patients eventually underwent allogeneic HCT. The estimated 3-year OS among patients proceeding to allogeneic HCT was 72% (95% CI 46%-87%). Our report details the pattern of post-AHCT relapse and the management of relapsed disease using different therapeutic modalities., (© 2024 The Authors.

Background: In retrospective analyses, the Pediatric Oncology Group [POG) and the Federation National des Centres de Lutte Contre le Cancer (FNCLCC) histologic grade predict outcome in pediatric non-rhabdomyosarcoma soft tissue sarcoma (NRSTS), but prospective data on grading, clinical features, and outcomes of low-grade NRSTS are limited., Methods: We analyzed patients less than 30 years of age enrolled on Children's Oncology Group (COG) study ARST0332 (NCT00346164) with POG grade 1 or 2 NRSTS. Low-risk patients were treated with surgery alone. Intermediate-/high-risk patients received ifosfamide/doxorubicin and radiotherapy, with definitive resection either before or after 12 weeks of chemoradiotherapy., Results: Estimated 5-year event-free and overall survival were 90% and 100% low risk (n = 80), 55% and 78% intermediate risk (n = 15), and 25% and 25% high risk (n = 4). In low-risk patients, only local recurrence was seen in 10%; none with margins greater than 1 mm recurred locally. Sixteen of 17 intermediate-/high-risk patients who completed neoadjuvant chemoradiotherapy underwent gross total tumor resection, 80% with negative margins. Intermediate-/high-risk group events included one local and seven metastatic recurrences. Had the FNCLCC grading system been used to direct treatment, 29% of low-risk (surgery alone) patients would have received radiotherapy ± chemotherapy., Conclusions: Most low-risk patients with completely resected POG low-grade NRSTS are successfully treated with surgery alone, and surgical margins greater than 1 mm may be sufficient to prevent local recurrence. Patients with intermediate- and high-risk low-grade NRSTS have outcomes similar to patients with high-grade histology, and require more effective therapies. Use of the current FNCLCC grading system may result in overtreatment of low-risk NRSTS curable with surgery alone., (© 2024 Wiley Periodicals LLC.)

Opinion Statement: For adult patients diagnosed with relapsed B cell-ALL (B-ALL), there have been significant improvements in available treatment options following the FDA approval of novel cellular and immunotherapy approaches - blinatumomab, chimeric antigen receptor (CAR) T therapy, and inotuzumab. For the last several years, research has focused on gaining a better understanding of the effects of specific disease and patient characteristics on long-term outcomes with each of the FDA-approved agents. In combination with the better prevention and management of unique, treatment-specific toxicities, providers can now select the best available treatment option for each individual patient diagnosed with relapsed, adult B-ALL needing therapy. This has allowed more patients to proceed to consolidative hematopoietic stem cell transplant (HSCT), and long-term data has even brought into question the need for HSCT for long-term durable remission for all patients. However, with the adoption of blinatumomab, CAR T therapy, and inotuzumab in front-line treatment regimens, it remains unclear what effects this will have on patients with relapsed B-ALL following exposure to these novel cellular and immunotherapy therapies. Unlike B-ALL, similar advances have unfortunately not yet been realized in T cell-ALL (T-ALL). Currently, new therapeutic approaches are underway to utilize similar targeting strategies that have been successful in B-ALL - monoclonal antibodies, bispecific T-cell engagers (BiTE), and CAR T therapy. Like B-ALL, the only existing approved therapy for relapsed T-ALL, nelarabine, is now used in the upfront treatment setting potentially limiting its utility in relapsed disease. Over the next several years, the hope is for patients diagnosed with T-ALL to experience the drastic improvement in outcomes as has been seen for patients diagnosed with B-ALL over the last decade., (© 2024.

Background/objectives: The Berlin-Frankfurt-Münster (BFM)-S classification is a crucial prognostic indicator in children experiencing first-relapsed acute lymphoblastic leukemia (ALL). Early molecular response to therapy, evaluated by measurable/minimal residual disease (MRD), has a significant impact on the survival of patients with childhood ALL. Applying risk stratification based on the BFM-S classification and MRD response after induction, the first nationwide prospective multicenter study, ALL-R08, was conducted in children with first-relapsed ALL in Japan., Methods: The ALL-R08 study comprised two parts: ALL-R08-I, an observational study aimed at obtaining an overall picture of outcomes in first-relapsed childhood ALL, and ALL-R08-II, a clinical trial for the non-T-ALL S2 risk group. In ALL-R08-II, patients with an MRD level of ≥10 -3 at the end of induction therapy were assigned to undergo allogeneic hematopoietic stem cell transplantation (allo-HCT), whereas those with an MRD level less than 10 -3 and isolated extramedullary relapse continued to receive chemotherapy., Results: In total, 163 patients were enrolled in the ALL-R08 study, and 82 and 81 patients were enrolled in the ALL-R08-I and the ALL-R08-II, respectively. In ALL-R08-I, the probability of 3-year event-free survival (EFS) for patients with S1, S2, S3, S4, and post-HCT groups was 83% ± 15%, 37% ± 11%, 28% ± 8%, 14% ± 7%, and 0%, respectively. In the ALL-R08-II trial, 3-year EFS in patients with post-induction MRD less than 10 -3 and ≥10 -3 was 70% ± 9% (n = 27) and 68% ± 8% (n = 31) (p = .591), respectively., Conclusions: ALL-REZ BFM-type treatment is equally effective for children with first-relapsed ALL treated according to the Japanese frontline protocols and for children with first-relapsed ALL treated according to the BFM-type frontline protocols., (© 2024 The Authors.

Purpose: To investigate the extent to which three systematic approaches for prioritizing symptoms lead to similar treatment advices in cancer survivors with co-occurring fear of cancer recurrence, depressive symptoms, and/or cancer-related fatigue., Methods: Psychological treatment advices were was based on three approaches: patient preference, symptom severity, and temporal precedence of symptoms based on ecological momentary assessments. The level of agreement was calculated according to the Kappa statistic., Results: Overall, we found limited agreement between the three approaches. Pairwise comparison showed moderate agreement between patient preference and symptom severity. Most patients preferred treatment for fatigue. Treatment for fear of cancer recurrence was mostly indicated when based on symptom severity. Agreement between temporal precedence and the other approaches was slight. A clear treatment advice based on temporal precedence was possible in 57% of cases. In cases where it was possible, all symptoms were about equally likely to be indicated., Conclusions: The three approaches lead to different treatment advices. Future research should determine how the approaches are related to treatment outcome. We propose to discuss the results of each approach in a shared decision-making process to make a well-informed and personalized decision with regard to which symptom to target in psychological treatment., Implications for Cancer Survivors: This study contributes to the development of systematic approaches for selecting the focus of psychological treatment in cancer survivors with co-occurring symptoms by providing and comparing three different systematic approaches for prioritizing symptoms., (© 2023.

Third-generation chimeric antigen receptor T cells (CARTs) for relapsed or refractory (r/r) chronic lymphocytic leukemia (CLL) may improve efficacy compared to second-generation CARTs due to their enhanced CAR design. We performed the first phase 1/2 investigator-initiated trial evaluating escalating doses of third-generation CARTs (HD-CAR-1) targeting CD19 in patients with r/r CLL and B-cell lymphoma. CLL eligibility criteria were failure to two therapy lines including at least one pathway inhibitor and/or allogeneic hematopoietic cell transplantation. Nine heavily pretreated patients received HD-CAR-1 at dose levels ranging from 1 × 10 6 to 200 × 10 6 CART/m 2 . In-house HD-CAR-1 manufacturing was successful for all patients. While neurotoxicity was absent, one case of grade 3 cytokine release syndrome was observed. By day 90, six patients (67%) attained a CR, five of these (83%) with undetectable MRD. With a median follow-up of 27 months, 2-year PFS and OS were 30% and 69%, respectively. HD-CAR-1 products of responders contained significantly more CD4 + T cells compared to non-responders. In non-responders, a strong enrichment of effector memory-like CD8 + T cells with high expression of CD39 and/or CD197 was observed. HD-CAR-1 demonstrated encouraging efficacy and exceptionally low treatment-specific toxicity, presenting new treatment options for patients with r/r CLL. Trial registration: #NCT03676504., (© 2024.

Testicular germ cell tumors are the most common tumors in adolescent and young men. They are curable malignancies that should be treated with curative intent, minimizing acute and long-term side effects. Inguinal orchiectomy is the main diagnostic procedure, and is also curative for most localized tumors, while patients with unfavorable risk factors for recurrence, or those who are unable or unwilling to undergo close follow-up, may require adjuvant treatment. Patients with persistent markers after orchiectomy or advanced disease at diagnosis should be staged and classified according to the IGCCCG prognostic classification. BEP is the most recommended chemotherapy, but other schedules such as EP or VIP may be used to avoid bleomycin in some patients. Efforts should be made to avoid unnecessary delays and dose reductions wherever possible. Insufficient marker decline after each cycle is associated with poor prognosis. Management of residual masses after chemotherapy differs between patients with seminoma and non-seminoma tumors. Patients at high risk of relapse, those with refractory tumors, or those who relapse after chemotherapy should be managed by multidisciplinary teams in experienced centers. Salvage treatment for these patients includes conventional-dose chemotherapy (TIP) and/or high-dose chemotherapy, although the best regimen and strategy for each subgroup of patients is not yet well established. In late recurrences, early complete surgical resection should be performed when feasible. Given the high cure rate of TGCT, oncologists should work with patients to prevent and identify potential long-term side effects of the treatment. The above recommendations also apply to extragonadal retroperitoneal and mediastinal tumors., (© 2024. The Author(s).)

The one-year survival rate for patients experiencing a relapse of B-cell acute lymphocytic leukemia (B-ALL) following hematopoietic stem cell transplantation (HSCT) is approximately 30%. Patients experiencing a relapse after allogeneic HSCT frequently encounter difficulties in obtaining autologous CAR-T products. We conducted a study involving 14 patients who received donor-derived CAR-T therapy for relapsed B-ALL following HSCT between August 2019 and May 2023 in our center. The results revealed a CR/CRi rate of 78.6% (11/14), a GVHD rate of 21.4% (3/14), and a 1-year overall survival (OS) rate of 56%. Decreased bone marrow donor cell chimerism in 9 patients recovered after CAR-T therapy. The main causes of death were disease progression and infection. Further analysis showed that GVHD (HR 7.224, 95% CI 1.42-36.82, P = 0.017) and platelet recovery at 30 days (HR 6.807, 95% CI 1.61-28.83, P = 0.009) are significantly associated with OS after CAR-T therapy. Based on the findings, we conclude that donor-derived CAR-T cells are effective in treating relapsed B-ALL patients following HSCT. Additionally, GVHD and poor platelet recovery impact OS, but further verification with a larger sample size is needed., Competing Interests: Declaration of Competing Interest The authors of this manuscript declare that they have no conflicts of interest., (Copyright © 2024 International Society for Cell & Gene Therapy.

In this review focused on lymphoma and the central nervous system (CNS), we summarize recent developments in the management of primary (PCNSL) and secondary CNS lymphoma (SCNSL), treatment of CNS lymphoma in the older population, the neuroradiological assessment of CNS lymphoma and finally highlight the ongoing debate on optimal CNS prophylaxis. The section on PCNSL focuses on the different approaches available for frontline treatment in Europe and the United States and discusses consolidation strategies. We then highlight available strategies to treat PCNSL in the elderly population, an area of unmet need. New therapies aiming at minimizing toxicity and prioritizing quality of life are emerging for these patients. Secondary CNS lymphoma, especially in the relapsed/refractory setting is another area of unmet need, and the efficacy of CAR-T cell therapy is being explored. We provide an overview of the imaging challenges in the neuroradiological assessment of CNS lymphoma. Finally, the section on CNS prophylaxis summarizes recent findings from large retrospective studies challenging the efficacy of present approaches to prophylaxis in higher-risk patients with lymphoma., (© 2023 John Wiley & Sons Ltd.)

Background: The development of CAR-T-cell immunotherapy has notably elevated the efficacy of treating multiple myeloma. Currently, a variety of targets, including BCMA, CS1, CD38, FcRH5, and GPRC5D, are being investigated. Despite these significant advancements, challenges such as antigen escape, limited persistence of CAR-T cells, and the intricate nature of the tumor microenvironment persist, leading to relapses following treatment., Case Presentation: We report the case of a patient with recurrent and refractory multiple myeloma (RRMM) who developed a substantial extramedullary plasmacytoma in the muscles of the lower limb following multiple rounds of radiotherapy and chemotherapy. The patient underwent CAR-T-cell immunotherapy targeting BCMA and CS1; however, the tumor progressed despite treatment. Surgical resection of the extramedullary plasmacytoma was subsequently performed. Upon comparison of the tumor tissue with the adjacent tissue, increased expression of MYBL2 was noted in the tumor tissue, potentially contributing to the lack of improvement in extramedullary relapse after dual-targeted CAR-T cell therapy., Conclusions: In patients with recurrent and refractory multiple myeloma who underwent multiple cycles of chemotherapy and radiotherapy, dual-targeted CAR-T cell therapy aimed at BCMA and CS1 failed to effectively manage extramedullary relapse. Elevated expression of MYBL2 in multiple myeloma correlates with a poorer prognosis., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Shi, Wu, Yao, Du and Du.)

Background: Low false negative rates can be achieved with sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NAC) in breast cancer (BC) patients with clinical N1 (cN1) disease. We examined changes in axillary management and oncologic outcomes in BC patients with cN1 disease receiving NAC., Methods: BC patients with biopsy proven cN1 disease treated with NAC were selected from our institutional cancer registry (2014-2017). Patients were grouped by axillary management, axillary lymph node dissection (ALND), SLNB followed by ALND, or SLNB alone. Univariable and multivariable survival analysis for recurrence-free survival (RFS) and overall survival (OS) were performed., Results: 81 patients met inclusion criteria: 31 (38%) underwent ALND, 25 (31%) SLNB + ALND, and 25 (31%) SLNB alone. A SLN was identified in 45/50 (90%) patients who had SLNB. ALND was performed in 25/50 (50%) patients who had SLNB: 18 for a + SLNB, 5 failed SLNB, and 2 insufficient SLNs. 25 patients had SLNB alone, 17 were SLN- and 8 SLN+. In the SLNB alone group, 23/25 (92%) patients received adjuvant radiation (RT). 20 (25%) patients developed BC recurrence: 14 distant (70%), 3 local (15%), 2 regional + distant (10%), and 1 contralateral (5%). In the SLNB alone group, there was 1 axillary recurrence in a patient with a negative SLNB who did not receive RT. Univariable survival analysis showed significant differences in RFS and OS between axillary management groups, ALND/SLNB + ALND vs. SLNB alone (RFS: p = 0.006, OS: p = 0.021). On multivariable survival analysis, worse RFS and OS were observed in patients with TNBC (RFS: HR 3.77, 95% CI 1.70-11.90, p = 0.023; OS: HR 8.10, 95% CI 1.84-35.60, p = 0.006)., Conclusions: SLNB alone and RT after NAC in BC patients with cN1 disease who have negative SLNs at surgery provides long-term regional disease control. This analysis provides support for the practice of axillary downstaging with NAC and SLNB alone., (© 2024. The Author(s).)

Abstract: Optimal treatment in patients with refractory or relapsed peripheral T-cell lymphomas (R/R T-NHLs) is unknown. In this population-based study, outcomes in R/R peripheral T-cell lymphoma not otherwise specified (PTCL NOS), angioimmunoblastic T-cell lymphoma (AITL), and anaplastic lymphoma kinase-positive (ALK+) and ALK-negative (ALK-) anaplastic large cell lymphoma (ALCL) were evaluated. Patients with PTCL NOS, AITL, ALK+ ALCL, and ALK- ALCL (≥18 years) diagnosed in 2014 to 2019 were identified using the Netherlands Cancer Registry. End points were overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). The 2-year PFS of 821 patients was 57%. Among 311 patients with a relapse, 243 received second-line treatment: 44% received salvage chemotherapy, 20% received brentuximab vedotin (BV), and 36% received other treatment. In third-line treatment, BV was most commonly used (38%). ORR after second-line treatment was 47%. Two-year PFS and OS after relapse were 25% and 34%, respectively. The risk of second relapse was negatively affected by early relapse (<12 months after diagnosis), whereas BV reduced this risk compared with salvage chemotherapy. Reduced risk of relapse was independent of histological subtype. The best outcomes were observed for patients treated with salvage chemotherapy receiving consolidative autologous and allogeneic stem cell transplantation (SCT) (2-year OS 68%), patients treated with BV achieving a second complete remission (2-year OS 74%) and patients with allogeneic SCT (2-year OS 60%). The risk of second relapse was significantly lower for patients with R/R T-NHL treated with BV compared with patients treated with salvage chemotherapy, and this was irrespective of subtype. Therefore, the use of salvage chemotherapy for patients with R/R T-NHL is challenged., (© 2024 by The American Society of Hematology.

Three classes of BCMA-directed therapy (BDT) exist: antibody drug-conjugates (ADCs), CAR-T, and T-cell engagers (TCEs), each with distinct strengths and weaknesses. To aid clinicians in selecting between BDTs, we reviewed myeloma patients treated at Mayo Clinic with commercial or investigational BDT between 2018-2023. We identified 339 individuals (1-exposure = 297, 2-exposures = 38, 3-exposures = 4) who received 385 BDTs (ADC = 59, TCE = 134, CAR-T = 192), with median follow-up of 21-months. ADC recipients were older, with more lines of therapy (LOT), and penta-refractory disease. Compared to ADCs, CAR-T (aHR = 0.29, 95%CI = 0.20-0.43) and TCEs (aHR = 0.62, 95%CI = 0.43-0.91) had better progression-free survival (PFS) on analysis adjusted for age, the presence of extramedullary (EMD), penta-refractory disease, multi-hit high-risk cytogenetics, prior BDT, and the number of LOT in the preceding 1-year. Likewise, compared to ADCs, CAR-T (aHR = 0.28, 95%CI = 0.18-0.44) and TCEs (aHR = 0.60, 95%CI = 0.39-0.93) had superior overall survival. Prior BDT exposure negatively impacted all classes but was most striking in CAR-T, ORR 86% vs. 50% and median PFS 13-months vs. 3-months. Of relapses, 54% were extramedullary in nature, and a quarter of these cases had no history of EMD. CAR-T demonstrates superior efficacy and where feasible, should be the initial BDT. However, for patients with prior BDT or rapidly progressive disease, an alternative approach may be preferable., (© 2024. The Author(s).)
