After experimentation with different kinds of particles, including neutrons, mesons, helium ions, and neon ions, the National Institute of Radiological Sciences in Japan started using carbon ions for cancer treatment. Proton therapy has the physical advantage of the Bragg peak, which can well realize the high-dose distribution in the tumor target volume and the low-dose distribution in surrounding normal tissue, so proton therapy has found wide applications in the field of ion radiotherapy. Nevertheless, the physical dose distribution and biological characteristics of carbon ions are significantly superior to those of other particles. Compared with the conventional photon radiotherapy, carbon ion radiotherapy stands outwith its favorable radiophysical and biological advantages.1 In the current clinical practice, heavy ion radiotherapymainly refers to the carbon ion radiotherapy. So far, although some textbooks and publications have provided references for standardized applications of ion radiotherapy, there has not yet been any consensus to guide clinical practices. With the rapid development of ion radiotherapy in China, and the increase of proton and heavy ion therapy centers, ion radiotherapy, which serves as a promising radiotherapy technology, has been applicable to more and more indications.

Radiotherapy plays an important role in the comprehensive treatment of esophageal carcinoma. Standardized diagnosis and treatment based on the suggestions of a multidisciplinary team (MDT) form its foundation. For operable esophageal carcinoma, surgery after neoadjuvant chemoradiotherapy is the standard treatment; contrarily, for inoperable esophageal carcinoma, radical chemoradiotherapy is the only treatment option, and postoperative adjuvant radiotherapy can improve local control and survival rates in selected cases. Owing to the rapid technological development in radiotherapy, three-dimensional conformal radiotherapy, intensity-modulated radiotherapy, and image guidance technology are widely used in the treatment of esophageal carcinoma. Though drugs for treating cancer have been developed rapidly, we need to explore their optimal combination with radiotherapy, including chemotherapy, targetedor immune, and radiosensitizers. Esophageal carcinoma in China differs greatly from that in European and American countries in terms of etiology, pathological type, highincidence site, etc. Therefore, the European and American guidelines on radiotherapy for esophageal carcinoma cannot be applied in clinical practice in China.

However, it is challenging to deliver definitive doses to the pGTV and regional LNs without exceeding the tolerance of the organs at risk (OAR). Iodine‐125 (I‐125) brachytherapy has recently been applied in clinical practice for the treatment of malignant tumors. Its merits include a higher dose to the primary tumor lesion and lower dose surrounding the tumor mass. Using brachytherapy in these settings may maximize the dose delivered to the pGTV while minimizing the dose delivered to the OAR. I‐125 brachytherapy combined with IMRT for the treatment of LA‐NSCLC has rarely been reported. Here we report a patient with peripheral squamous cell carcinoma of the lung who received I‐125 brachytherapy for pulmonary lung lesions and IMRT for metastatic mediastinal LNs. The patient received 16 months of follow‐up care with no evidence of complications or disease recurrence. Moreover, we compared brachytherapy plus IMRT to theoretically planned IMRT dosimetry to evaluate the merits of each approach. This treatment modality resulted in a higher target dose escalation and lower doses delivered to the OAR.","PeriodicalId":32406,"journal":{"name":"Precision Radiation Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/pro6.1121","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44204391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this report, we describe a rare case of a 32‐year‐old female patient who presented with leiomyosarcoma. Initially, the patient complained of moderate‐intensity pain in the abdominal region of the right hypochondrium and nausea, worsening postprandial starting 6 days earlier. Abdominal ultrasonography showed a heterogeneous hypoechoic expansive formation, with lobulated contours and ill‐defined limits in the projection of the IVC. Inferior vena cavography, showed obliteration of the vessel in almost all of its extensions. Magnetic resonance examination showed a large expansive lesion occupying the IVC. The lesion was resected, and the specimen was sent for anatomopathological analysis, which showed a leiomyosarcoma of the IVC. Patients with leiomyosarcoma have a poor prognosis, and early diagnosis and complete resection with free surgical margins are the only chance of long‐term survival. The report stands out due to the appearance of this condition in a young patient with no family history of this disease or other predisposing carcinogenic pathologies.","PeriodicalId":32406,"journal":{"name":"Precision Radiation Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/pro6.1118","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47010566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
