García","doi":"10.5772/intechopen.95984","DOIUrl":"https://doi.org/10.5772/intechopen.95984","url":null,"abstract":"Around 50% of cancer patients will require radiotherapy (RT) and 10–15% of these patients could be eligible for proton beam radiotherapy (PBT). Dosimetric advantages are undeniable, mainly in pediatric and reirradiation scenarios. Though, PBT facilities are scarce worldwide and the IAEA has reported 116 functional particle facilities, of which 98 are PBT, virtually absent in low- and middle-income countries (LMIC). The Latin America and Caribbean region represent a unique opportunity for a PBT center, as there are currently no functional facilities and current RT needs are significant. The challenges can be summarized as high initial investment and maintenance, geographic coverage, required baseline technology and certification, over-optimistic workload, unclear rates and reimbursement, unmet business plan and revenue expectations, and lack of trained human resources. Investment costs for a PBT facility are estimated to be at around 140 million euros; therefore, this seems unsuitable for LMIC. Mexico’s geographical advantage, GDP, baseline technologies and high demand for RT makes it an ideal candidate. Nevertheless, a PBT center would account for a third of Mexico’s annual health expenditure for 2020. Enormous efforts must be made by both the private sector and governmental authorities to provide funding.","PeriodicalId":185991,"journal":{"name":"Proton Therapy - Current Status and Future Directions","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125557787","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}

With the growing use of proton therapy, there is a desire to prove the equivalence or superiority of proton therapy across a number of cancer disease sites. Dozens of clinical trials have been developed to accomplish this within individual institutions, among a few centers, and across national and international networks such as the National Cancer Institute’s National Clinical Trial Network. The protocols include proton therapy imbedded in trials with photon therapy as well as randomized photon vs. proton trials.

The number of installed proton units and the available medical evidence has grown exponentially over the last 10 years. As a technology driven cancer treatment modality, specific sub-analysis based on proton beam characteristics and proton beam generators is feasible and of academic interest. International synchrotron technology-based institutions have been particularly active in evidence generating actions including the design of prospective trials, data registration projects and retrospective analysis of early clinical results. Reported evidence after 2010 of proton therapy from synchrotron based clinical results are reviewed. Physics, molecular, cellular, animal investigation and other non-clinical topics were excluded from the present analysis. The actual literature search (up to January 2020) found 192 publications, including description of results in over 29.000 patients (10 cancer sites and histological subtypes), together with some editorials, reviews or expert updated recommendations. Institutions with synchrotron-based proton therapy technology have shown consistent and reproducible results along the past decade. Bibliometrics of reported clinical experiences from 2008 to early 2020 includes 58% of publications in first quartile (1q) scientific journals classification and 13% in 2q (7% 3q, 5% 4q and 17% not specified).
