Abstract
The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has drastically affected healthcare delivery to cancer patients, including those with malignant bone tumors, worldwide. Such cancer patients are more susceptible to COVID-19 infection and risk contracting the severe disease, but their holistic tumor management has also suffered a significant impact. Because of the acute shortage of healthcare resources due to their diversion in COVID management, substantial changes are needed in various aspects of management for high-grade tumor patients, particularly in developing countries and population-dense regions, so that their evidence-based appropriate treatment is ensured. Owing to a lack of consensus regarding the ideal course of action for the management of malignant bone tumors in the current situation, many such patients often get neglected, leading to loss of life/limb. This review elaborates on various guidelines proposed by different healthcare organizations and institutes regarding the modified care pathways for malignant bone neoplasms in the current coronavirus pandemic. The early published results of these modified care pathways and the changes in the oncology practice brought about by the pandemic are also discussed.Entities:

High-Priority Recommendations for Diagnostic Facilities
SELNET: Sarcoma European and Latin American Network; ESMO: European Society of Medical Oncology
| SELNET [ | ESMO [ |
| New bone lesion having suspicion of malignancy | Diagnostic imaging studies (MRI/CT scan) to confirm the diagnosis for patients having suspected sarcomas |
| Those lesions having the risk of pathologic fracture | Biopsy to confirm the diagnosis (image-guided or clinically guided) for patients having suspected sarcomas |
| Giant cell tumor/osteochondroma suspected of malignant transformation | Diagnostic imaging studies, biopsy with pathology assessment, and echocardiography in patients having indication of anthracyclines, in cases of relapsed tumors |
| Those lesions having suspicion of local recurrence | Restaging studies in order to monitor the response to active treatments, although such studies can be done at relatively longer intervals |
| New bone tumors already having metastases | |
| Any new metastatic recurrence having abnormal behavior for the particular tumor |
High-Priority Recommendations for the Surgical Management of Bone Tumors
SELNET: Sarcoma European and Latin American Network; ESMO: European Society of Medical Oncology
| Cardoso et al. [ | IRCCS Regina Elena National Cancer Institute, Italy [ | SELNET [ | ESMO [ |
| Sarcomas where surgery is first/unique curative treatment, such as chondrosarcoma | Biopsy in bone lesions with a suspicion of cancer and rebiopsy in cases where the previous biopsy was inconclusive | High-grade conventional osteosarcoma and chondrosarcoma | Ewing’s sarcoma |
| Surgery for sarcoma after NACT (osteosarcoma, Ewing’s sarcoma) | Curative resection of the biopsy-proven malignant bone tumor or its recurrence | Mesenchymal chondrosarcoma | Osteosarcoma |
| Recurrent sarcomas without any metastasis amenable to resection | Wide resection of malignant bone tumor planned for 3D printed/custom-made endoprosthesis | Skeletal Ewing’s sarcoma after NACT | Surgical complications of any type |
| Impending or established pathologic fracture of proximal hip region or spine with cord compression | Fixation of impending/actual pathologic fractures | Other high-grade primary bone tumors | Cases with discordant biopsy reports and that are suspected to be malignant |
| Spine tumor with cord compression | Those with surgical complications | ||
| Management of any postoperative complications | High-grade/intermediate grade in local recurrence | ||
| Chondrosarcoma patients (as they are chemoresistant/radioresistant) | Metastatectomies as part of the multimodal management of osteosarcoma/Ewing’s sarcoma | ||
| Oligometastatic chondrosarcoma or other high-grade bone sarcomas without any evidence of local recurrence |
High-Priority Chemotherapy Indications for Bone Tumors
SELNET: Sarcoma European and Latin American Network; ESMO: European Society of Medical Oncology; NICE: National Institute for Health and Care Excellence
| French Sarcoma Group [ | SELNET [ | ESMO [ | NICE [ |
| Continue NACT and adjuvant regimens as previously for osteosarcoma/Ewing’s sarcoma | NACT in osteosarcoma/Ewing’s sarcoma as well as potentially resectable mesenchymal chondrosarcoma | NACT/adjuvant chemotherapy for osteosarcoma/Ewing’s sarcoma | Curative treatment with >50% chances of success and NACT/adjuvant treatment adding at least 50% chance of cure to surgery/radiotherapy alone |
| Continue the standard treatment for primary bone sarcomas with metastases | Chemotherapy in recurrent advanced osteosarcoma/Ewing’s sarcoma and metastatic undifferentiated high-grade bone sarcoma | Limit the use of dexamethasone | |
| Topotecan and cyclophosphamide for Ewing’s sarcoma in cases of metastatic relapse | Upfront chemotherapy in metastatic osteosarcoma/Ewing’s sarcoma | Encourage the use of G-CSF/EPO growth factor and antibiotics in order to decrease the chances of neutropenia | |
| Antiangiogenic treatment for osteosarcoma in cases of metastatic relapse |
High-Priority Indications for Radiotherapy in Bone Tumors
NICE: National Institute for Health and Care Excellence; ESMO: European Society of Medical Oncology; SELNET: Sarcoma European and Latin American Network
| NICE [ | ESMO [ | SELNET [ |
| Radical radiotherapy or chemoradiotherapy with curative intent, if treatment has already started and for those with category 1 (rapidly proliferating) tumors | Cases who are already in treatment | Skeletal Ewing’s sarcoma |
| External beam radiotherapy with brachytherapy, if it is already started and cases with category 1 tumors | Those with acute spinal cord compression, symptomatic brain metastases, or any other urgent palliative radiotherapy requirement | Definitive treatment of grade 3 chondrosarcoma |
| Those category 1 tumor cases who have not yet started treatment | Palliative treatment of bleeding/painful inoperable masses where symptoms cannot be resolved with medicines | Unresectable osteosarcoma after NACT |
| Any symptomatic metastatic lesion where relief is expected with radiotherapy |
