Oncological interventions in thoracic cavity have some important problems such as choice of correct operative approaches depending on the tumor, size, extension, and location. In sarcoma surgery, wide resection should be aimed for the curative surgery. Purpose of this study was to evaluate pre-operative planning of patient-specific thoracic cavity model made by multidisciplinary surgeon team for complex tumor mass for oncological procedures. Patient's scans showed a large mass encroaching on the mediastinum and heart, with erosion of the adjacent ribs and vertebral column. Individual model of this case with thoracic tumor was reconstructed from the DICOM file of the CT data. Surgical team including six interdisciplinary surgeons explained their surgical experience of the use of 3D life-size individual model for guiding surgical treatment. Before patients consented to surgery, each surgeon explained the surgical procedure and perioperative risks to her. A questionnaire was applied to 10 surgical residents to evaluate the 3D model's perception. 3D model scans were useful in determining the site of the lesion, the exact size, extension, attachment to the surrounding structures such as lung, aorta, vertebral column, or vascular involvement, the number of involved ribs, whether the diaphragm was involved also in which order surgeons in the team enter the surgery. 3D model's perception was detected statistical significance as < 0.05. Viewing thoracic cavity with tumor model was more efficient than CT imaging. This case was surgically difficult as it included vital structures such as the mediastinal vessels, aorta, ribs, sternum, and vertebral bodies. A difficult pathology for which 3D model has already been explored to assist anatomic visualization was mediastinal osteosarcoma of the chest wall, diaphragm, and the vertebral column. The study helped to establish safe surgical line wherever the healthy tissue was retained and enabled osteotomy of the affected spinal corpus vertically with posterior-anterior direction by preserving the spinal cord and the spinal nerves above and distal the tumor. 3D tumor model helps to transfer complex anatomical information to surgeons, provide guidance in the pre-operative planning stage, for intra-operative navigation and for surgical collaboration purposes. Total radical excision of the bone tumor and reconstructions of remaining structures using life-size model was the key for successful treatment and better outcomes. The recent explosion in popularity of 3D printing is a testament to the promise of this technology and its profound utility in orthopedic oncological surgery.

“…It can help doctors avoid accidentally damaging the normal tissue around the lesion area, and design plans to deal with possible emergencies. Doctors can obtain 3D virtual models by CT and MRI images, then export STL files, connect printers, and print surgical planning models by using technologies such as SLA (George et al, 2017; Hamabe & Ito, 2017), FDM, SLS (Krauel et al, 2016), and so forth.…”

Three‐dimensional (3D) printing technology is one of the hottest research fields nowadays, which has influenced the treatment methods in the medical industry. In order to explore the progress of 3D printing technology in medical applications, the authors conducted English retrieval with the keywords “three‐dimensionalprinting,” “bioprinting,” and “3D printing” in PubMed, and extracted information related to this exploration. This review firstly introduces the 3D printing materials, types of technology, and printing procedures in medical fields, then elaborates the current applications of 3D printing in medical devices, in vitro anatomical models, organ printing, implants, tissue engineering scaffolds, and the leap from 3D medical printing to four‐dimensional (4D) medical printing, finally put forward the shortage of the medical 3D/4D printing and possible solutions of them.

“…Superior sulcus (Pancoast) tumors frequently involve the pleura, bones, vessels, and nerves, and therefore present challenging management decisions that can be aided by 3D printing [ 5 , 6 ]. Specifically, the choice of whether to pursue surgical management can be swayed by a physical, 3D printed model.…”

In this work, we provide specific clinical examples to demonstrate basic practical techniques involved in image segmentation, computer-aided design, and 3D printing. A step-by-step approach using United States Food and Drug Administration cleared software is provided to enhance surgical intervention in a patient with a complex superior sulcus tumor. Furthermore, patient-specific device creation is demonstrated using dedicated computer-aided design software. Relevant anatomy for these tasks is obtained from CT Digital Imaging and Communications in Medicine images, leading to the generation of 3D printable files and delivery of these files to a 3D printer.Electronic supplementary materialThe online version of this article (10.1186/s41205-017-0022-3) contains supplementary material, which is available to authorized users.
