Median follow-up was 180 months. The preponderant histology was clear cell (85%). In 50% the initial diagnosis was advanced disease. The distribution according to IMDC prognosis was good (24%), intermediate (50%) and poor (26%). The most frequent metastatic locations were lung (68.3%) and lymph node (41.0%). Most patients (95%) received a first line (1L) systemic treatment, 60% were treated with a second line (2L) of therapy and 37% received third line (3L). A VEGFR-TKIs was the most common treatment (1L: 90%, <em>n =</em> 507; 2L: 49%, <em>n =</em> 233; 3L: 54%, <em>n =</em> 156) followed by mTOR inhibitors (1L: 2%, <em>n =</em> 4; 2L: 27%, <em>n =</em> 126; 3L: 23%, <em>n =</em> 68) and immunotherapy (1L: 3.7%, <em>n =</em> 25; 2L: 27%, <em>n =</em> 126). Median OS was 24.5 months in the general population. According to IMDC prognostic groups, OS was 52.5, 25.7 and 9 months respectively.

Despite the demonstrated clinical benefit in patients with r/r diffuse large B-cell lymphoma, mantle cell lymphoma, and follicular lymphoma, many patients who are eligible for CAR T-cell therapies do not receive them or are treated with CAR T cells as a later line of therapy at advanced stages of disease. Several barriers exist for referring patients to an authorized treatment center (ATC) for CAR T-cell therapy. Although most patients with NHL are treated by community-based oncologists, educational gaps may exist for some community oncologists about the availability of CAR T-cell therapies in certain indications, the overall treatment process, and how they can access these therapies for their patients. In addition to navigation of the referral process from the community setting to the ATC, other barriers include timely identification of candidates eligible for CAR T-cell therapy and logistical and reimbursement concerns. Here, we examine the patient CAR T-cell experience, which begins and ends in the community setting, and identify and discuss opportunities for improved collaboration between community oncologists and ATC physicians to help address barriers to treatment and enhance patient outcomes. Treatment decisions for a patient's second or third line of therapy for NHL are critically important, owing to declining probabilities for favorable outcomes with each successive line of therapy. For patients who are eligible, CAR T-cell therapies should be considered as early as possible in their treatment course. A better understanding of the CAR T-cell process, the patient's experience, and the collaboration necessary for timely patient identification, better access, and successful outcomes will enable more patients to benefit from CAR T-cell therapies.</p></div>","PeriodicalId":21750,"journal":{"name":"Seminars in oncology","volume":"51 3","pages":"Pages 87-94"},"PeriodicalIF":3.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0093775424000046/pdfft?md5=37592ae048944580f3ea166540526d16&pid=1-s2.0-S0093775424000046-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139949522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to cope, eukaryotic cells have evolved an elaborate network of DNA repair that can deal with diverse lesion types and exhibits considerable functional redundancy. PARP1 is a major sensor of DNA breaks with established and putative roles in a number of pathways within the DNA repair network, including repair of single- and double-strand breaks as well as protection of the DNA replication fork. Importantly, PARP1 is the major target of small-molecule PARP inhibitors (PARPi), which are employed in the treatment of homologous recombination (HR)-deficient tumors, as the latter are particularly susceptible to the accumulation of DNA damage due to an inability to efficiently repair highly toxic double-strand DNA breaks. The clinical success of PARPi has fostered extensive research into PARP biology, which has shed light on the involvement of PARP1 in various genomic transactions. A major goal within the field has been to understand the relationship between catalytic inhibition and PARP1 trapping. The specific consequences of inhibition and trapping on genomic stability as a basis for the cytotoxicity of PARP inhibitors remain a matter of debate. Finally, PARP inhibition is increasingly recognized for its capacity to elicit/modulate anti-tumor immunity. The clinical potential of PARP inhibition is, however, hindered by the development of resistance. Hence, extensive efforts are invested in identifying factors that promote resistance or sensitize cells to PARPi. The current review provides a summary of advances in our understanding of PARP1 biology, the mechanistic nature, and molecular consequences of PARP inhibition, as well as the mechanisms that give rise to PARPi resistance.</p></div>","PeriodicalId":21750,"journal":{"name":"Seminars in oncology","volume":"51 1","pages":"Pages 2-18"},"PeriodicalIF":4.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0093775423000611/pdfft?md5=84ff3c62330ada1df60673d49569a10e&pid=1-s2.0-S0093775423000611-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10317051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
