Impact of interstitial lung abnormality on survival after adjuvant durvalumab with chemoradiotherapy for locally advanced non-small cell lung cancer. Radiother Oncol 2023; 180:109454. [PMID: 36640944 DOI: 10.1016/j.radonc.2022.109454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 12/13/2022] [Accepted: 12/17/2022] [Indexed: 01/13/2023]
Abstract
INTRODUCTION Concurrent chemoradiotherapy (CCRT) has been the standard of care for patients with locally advanced non-small cell lung cancer (LA-NSCLC). BACKGROUND AND PURPOSE The results of the PACIFIC trial established the use of consolidative durvalumab after concurrent chemoradiotherapy (CCRT) as the standard of care for patients with locally advanced non-small cell lung cancer (LA-NSCLC). A subgroup analysis of the PACIFIC trial reported a better progression-free survival (PFS) in Asians. Although real-world data on LA-NSCLC patients who received CCRT plus durvalumab have been reported, there have been few large-scale reports on Asians. In this study, we investigated prognostic factors in the largest real-world data set in Asia of only Japanese LA-NSCLC patients treated with CCRT plus durvalumab. MATERIALS AND METHODS One hundred and thirteen LA-NSCLC patients who received definitive CCRT and consolidative durvalumab at our institution between May 2018 and April 2021 were analyzed. Overall survival (OS), cause-specific survival (CSS), PFS, distant metastasis-free survival (DMFS), and in-field progression-free survival (IFPFS) were investigated as treatment outcomes using competing risk analyses. RESULTS During a median follow-up of 24 months (range, 5-47) after the initiation of durvalumab therapy, 31 patients died, of whom 23 died of lung cancer. In the multivariate analysis, the pretreatment factors that correlated with OS were ILA scores, adenocarcinoma, and performance status at the initiation of durvalumab. Furthermore, ILA score and programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) ≥ 1 % were significantly correlated with CSS, and PD-L1 TPS ≥ 1 % was significantly correlated with PFS and IFPFS. CONCLUSION Pretreatment ILA, adenocarcinoma, and performance status may have an impact on OS of LA-NSCLC patients receiving CCRT plus durvalumab.

Prognostic factor analysis of definitive radiotherapy using intensity-modulated radiation therapy and volumetric modulated arc therapy with boluses for scalp angiosarcomas. Sci Rep 2022; 12:4355. [PMID: 35288619 PMCID: PMC8921322 DOI: 10.1038/s41598-022-08362-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2021] [Accepted: 03/07/2022] [Indexed: 11/24/2022] Open
Abstract
Cutaneous angiosarcomas is a rare cancer with poor prognoses. The common radiotherapy techniques that have been reported so far are two pairs of lateral X-ray and electron fields. However, it is quite difficult to irradiate scalp angiosarcomas (SAs) homogeneously with this technique. In this study, safety, effectiveness, and risk factors were assessed for localized SAs ≥ 5 cm treated with intensity-modulated radiotherapy (IMRT) or volumetric modulated arc therapy (VMAT) with boluses. Sixty-eight angiosarcoma patients who had received radiotherapy in our institution between January 2007 and November 2020 were retrieved from our radiotherapy database. Of these patients, 27 localized SA patients were included in the retrospective analysis. The 2-year overall survival, local progression-free rate, and distant metastases-free survival were 41.8%, 48.4%, and 33.1%. All the patients experienced acute radiation dermatitis ≥ grade 2, with18 (66.7%) ≥ grade 3. No nodule lesion was a significant unfavorable predictive factor of acute radiation dermatitis ≥ grade 3. Tumor bleeding at the initiation of radiotherapy and tumor invasion to the face were significant predictive factors of overall survival, and tumor bleeding at the initiation of radiotherapy was also a significant predictive factor of local progression-free rate.

Initial Experience of Intentional Internal High-Dose Policy Volumetric Modulated Arc Therapy of Neck Lymph Node Metastases ≥ 2 cm in Patients With Head and Neck Squamous Cell Carcinoma. Front Oncol 2021; 11:651409. [PMID: 33987086 PMCID: PMC8112241 DOI: 10.3389/fonc.2021.651409] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Accepted: 03/30/2021] [Indexed: 12/24/2022] Open
Abstract
Background and Purpose Most locoregional recurrences after definitive radiotherapy for head and neck squamous cell carcinoma (HNSCC) develop "in-field." Dose escalation while sparing organs at risk can be a good solution for improving local control without increasing adverse effects. This study investigated the safety and effectiveness of volumetric modulated arc therapy (VMAT) using intentionally internal high-dose policy (IIHDP) to treat neck lymph node metastases (NLNM) ≥ 2 cm in HNSCC patients. Materials and Methods We analyzed 71 NLNM from 51 HNSCC patients who had received definitive radiotherapy to treat NLNM ≥ 2 cm using the VMAT technique in our institution between February 2017 and August 2019. Thirty-seven NLNM from 25 patients were treated using IIHDP VMAT (group A), and 34 NLNM from 27 patients were treated with homogeneous-dose distribution policy (HDDP) VMAT (group B). One patient with three NLNM had one lymph node assigned to group A and the other two to group B. Adverse events and local recurrence-free survival (LRFS) was compared between the two groups. Results In the median follow-up period of 527 days, there were no significant differences between the groups in terms of dermatitis or mucositis ≥ grade 2/3, but LRFS was significantly longer in group A (p = 0.007). In the Cox regression analysis after adjustment for the propensity score, group A also showed an apparently superior LFRS. Conclusion Our initial experience of IIHDP VMAT suggested that IIHDP VMAT to treat HNSCC neck lymph node metastases measuring ≥ 2 cm was feasible and possibly led to better local control than HDDP VMAT.

Abstract
Background Cervical cancer is a public health problem in Latin America. Radiotherapy plays a fundamental role both as definitive or adjuvant treatment. There are important intra and inter-country differences regarding access and availability of radiotherapy facilities in this region. The aim of a study was to standardize the basic clinical and technical criteria for the radiation treatment of patients with CC in Chile and provide a guide for Latin American Radiation Oncologists. Materials and methods Forty-one expert radiation oncologists from the Chilean Radiation Oncology Society made a consensus using the Delphi methodology. Results There was a high degree of agreement for each of the recommendations. Those with the lowest percentage were related to the definition of the conformal 3D technique as the standard for definitive external radiotherapy (81%) and the criteria for extended nodal irradiation (85%). Conclusions These recommendations present an updated guide for radiotherapy treatment of patients with cervical cancer for Latin America. Those should be implemented according to local resources of each institution.
