In advanced NSCLC, ICI treatment was linked to an elevated risk of pneumonitis across all grades (1-5) as well as high-grade occurrences (3-5) compared to chemotherapy. Notably, individuals with squamous histology and high PD-L1 expression, along with those lacking a history of prior treatment, demonstrated a heightened susceptibility to developing immune-related pneumonitis of all grades (1-5) and high grades (3-5). These observations provide valuable insights for clinicians seeking to enhance the management of pulmonary toxicity associated with immunotherapy.

We discuss the role of NGS as well as its potential benefit in patients with unresectable, ALK-negative metastatic disease. Considering this case and previous literature, we support the use of NGS for patients requiring systemic treatment.

Three cases previously classified as PTCL CD30+CD15+ showed DUSP22/IRF4 rearrangements, favouring a diagnosis of ALCL, ALK-. Our results suggest that cases previously designated PTCL CD30+CD15+, likely fall within the spectrum of ALCL, ALK-; additionally, a subset of ALCL, ALK- with DUSP22/IRF4 rearrangement expresses CD15, consistent with previous reports and expands the immunophenotypic spectrum of this lymphoma subgroup.

The histologic features of CSM present a unique set of challenges posing a diagnostic dilemma, as they can bear resemblance to a range of benign and malignant cutaneous neoplasms including ALK-negative epithelioid cell histiocytoma, epithelioid perineurioma, malignant or nevoid melanoma, and epithelioid sarcoma. An accurate diagnosis is crucial for guiding proper clinical management considering that this entity typically demonstrates an excellent prognosis following a complete surgical excision.

Symptoms of androgen deficiency should be tracked in male patients with ALK-positive ANSCLC who are receiving alectinib, and testosterone replacement should be considered, as appropriate.

This study demonstrated that participating in clinical trials resulted in a survival benefit that reduced the risk of death by 29.6% compared to receiving SOC in EGFR-wild-type and ALK-negative lung adenocarcinoma.

While combination of these factors was highly predictive for ICIs, it was not associated with outcomes of chemotherapy treatment. Easily available characteristics of the patients allow for highly accurate predictions of outcomes of single-agent ICI therapy in chemotherapy-pretreated NSCLC.

In conclusion, 44% of ALCL patients, regardless of histological subtypes, showed a loss of/decrease in CD30 expression after receiving BV-containing therapy, but this phenomenon was not observed in CHL patients. A higher cumulative dose of BV and a lower amount of CD30 antigen in tumor cells in the initial biopsy materials might be predictors of a loss of/decrease in CD30 expression in ALCL patients.

As a unique class of tumors that rarely metastasize, IMTs have an unknown etiology and pathogenesis, and distant metastasis is primarily observed in patients with negative activin receptor-like kinase (ALK) expression. The preferred treatment for IMT is complete surgical resection, and the effectiveness of adjuvant therapy for patients with distant metastases is still being determined. The clinical presentation of IMT lacks specificity and is often related to the location of tumor growth, which poses a diagnostic challenge. Pathological immunohistochemistry is the only way to confirm the diagnosis at present. Our case report reminds clinicians that a category of ALK-negative IMT with a tendency toward distant metastasis should not be ignored.

We showed that following first-line immunochemotherapy, chemo-free maintenance by ICIs plus anti-angiogenesis and on-demand chemo-rechallenge provided comparable efficacy to chemo-on maintenance in terms of PFS, thus allowing the minimization of cytotoxic drugs without compromising therapeutic effectiveness. In addition, anti-angiogenesis is essential during chemo-free maintenance.

We subsequently stained whole tissue sections of these three cases with the ALK01 antibody and found that these three cases were indeed positive with the ALK01 protocol, suggesting that the absence of staining on the tissue microarray samples was due to a combination of sampling error as well as a dimmer signal with the ALK01 protocol. Our study demonstrates that our 5A4-based protocol is non-inferior to the ALK01 antibody for the diagnosis of ALK-positive anaplastic large cell lymphoma, thus allowing our laboratory to discontinue the use of the ALK01-based protocol.

Furthermore, in a subset of patients with initial site of progression at a non-primary-site, patients undergoing concurrent immunotherapy had longer PFS than those undergoing consolidative immunotherapy (median 22.7 vs. 11.9 months; P=0.03). Concurrent immunotherapy with chemoradiotherapy may be associated with improved disease progression outcomes as compared to consolidative immunotherapy following chemoradiotherapy.

The small group of primary nodal Epstein-Barr virus-positive lymphomas of T- or NK-cell derivation, formerly considered PTCL, NOS, is now classified separately, due to distinctive features, and notably an aggressive course. This review summarizes current knowledge of the pathology and biology of nodal-based PTCL entities, with an emphasis on recent findings and underlying oncogenic mechanisms.

Thirty-two patients received myeloablative conditioning (MAC), eighteen of which included total body irradiation (TBI) and 15 of which included busulfan (BU)...Three patients survived at the last follow up, and the median follow-up time of survivors from relapse was 430 days (range, 12-1301). [Conclusion] Our data indicated good results of allo-HSCT for R/R PTCL, and significantly better in relapse after first remission patients.

Background: The standard first-line treatment for peripheral T-Cell Lymphoma (PTCL) is cyclophosphamide, doxorubicin, vincristine, and prednison (CHOP),but the treatment effect is poor,the 5-year overall survival(OS) was only 30-40%. From 3/2021 to 7/2023, 35 subjects with previously untreated PTCL were enrolled in chongqing university cancer hospital, and the study met its accrual. At study entry, 22 patients (62. 8%) were angioimmu-noblastic T-cell lymphoma(AITL),4 patients (11.

Grade >= 3 treatment-related adverse events were more frequent in the experimental arm (OR 1.22). The experimental treatment improved surgical outcomes, pCR rates, EFS and OS in stage II-IIIB, EGFR/ALK negative resectable NSCLC; confirmatory evidence is warranted for stage IIIB tumours and with higher maturity of the OS endpoint.

This rare variant of ENKTL, characterized by the predominance of anaplastic cells and diffuse CD30 expression, exhibits high aggressiveness and should be differentiated from ALK-negative ALCL. Awareness of this uncommon variant is crucial in preventing misdiagnosis and ensuring the timely initiation of therapy.

LIMITLESS is an ongoing prospective, multicenter, parallel-arm, open-label RCT that randomizes patients with NSCLC-BM on pembrolizumab monotherapy prescribed as per standard-of-care to LIFU plus pembrolizumab (arm 1) or pembrolizumab alone (arm 2) in 2:1 ratio...Exploratory outcomes are median PFS, OS, intracranial PFS, extracranial PFS, and quality of life. Clinical trial information: NCT05317858.

EML4-ALK fusion protein may enhance venous thrombogenicity by regulating coagulation factor TF expression. There was potential involvement of the pERK1/2-AP-1 pathway in this process.

METHODSLIMITLESS is an ongoing prospective, multicenter, parallel-arm, open-label RCT that randomizes patients with NSCLC BM on pembrolizumab monotherapy prescribed as per standard-of-care to LIFU plus pembrolizumab (arm 1) or pembrolizumab alone (arm 2) in 2:1 ratio...RESULTS Patient enrollment commenced in 2022. CONCLUSION Findings from this trial will be critical to liquid biopsy in brain metastases.

Objective: To investigate the clinical-pathology characteristics, risk factors, necessary for VBL maintenance therapy,through summarize the clinical data of 221 cases of pediatric Anaplastic Large Cell Lymphoma (ALCL), treated with CNCL-ALCL-2017 witch is modify from BFM-ALCL-99 (±vincristine maintenance therapy) in China Net Childhood Lymphoma (CNCL)...Adverse prognostic factors include a significant increase in LDH levels at initial diagnosis, initial onset of HLH, positive MDD before treatment, and no use of vinblastine maintenance therapy. Pediatric ALCL in China is mostly found in school-age boys, and it is easy to be diagnosed as infectious diseases at the time of initial diagnosis due to high fever and elevated CRP. 87% of patients were diagnosed as late stage or high-risk group. The application of the CNCL-ALCL-2017 protocol showed a 3-year OS 84.7% and 3-year EFS 95.1%, indicating that the efficacy was significantly better than that of various centers before the multi center cooperation.

Conclusions Despite the presence of BV-refractory disease, 4 cycles of BV and nivolumab is tolerable and associated with encouraging efficacy in patients with heavily treated CD30+ lymphoma. This treatment option may have increasing relevance as more patients receive BV or anti-PD-1 therapy as part of initial treatment.

The most frequent non-hematologic toxicities included skin rash (40%), nausea (35%), and diarrhea (20%) however, they were manageable. Conclusions The lenalidomide maintenance might be a feasible and effective treatment approach for patients with relapsed or refractory PTCLs who are ineligible for ASCT or intensive consolidation chemotherapy.
