Here, we describe positive treatment outcomes in three patients using Rigvir virotherapy. One of the patients is diagnosed with melanoma stage IV M1c, one with small cell lung cancer stage IIIA, and one with histiocytic sarcoma stage IV. The diagnoses of all patients are verified by histology or cytology. All patients started Rigvir treatment within a few months after being diagnosed and are currently continuing Rigvir treatment. The degree of regression of the disease has been determined by computed tomography. Safety assessment of adverse events graded according to NCI CTCAE did not show any value above grade 1 during Rigvir<jats:sup>\u00ae<\/jats:sup> treatment. Using current standard treatments, the survival of patients with the present diagnoses is low. In contrast, the patients described here were diagnosed 3.5, 7.0, and 6.6 years ago, and their condition has improved and been stabile for over 1.5, 6.5, and 4 years, respectively. These observations suggest that virotherapy using Rigvir can successfully be used in long\u2010term treatment of patients with melanoma stage IV M1c, small cell lung cancer stage IIIA, and histiocytic sarcoma stage IV and therefore could be included in prospective clinical studies.<\/jats:p>","DOI":"10.1111\/apm.12576","type":"journal-article","created":{"date-parts":[[2016,7,26]],"date-time":"2016-07-26T05:17:30Z","timestamp":1469510250000},"page":"896-904","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":46,"title":["Long\u2010term treatment with the oncolytic ECHO\u20107 virus Rigvir of a melanoma stage IV M1c patient, a small cell lung cancer stage IIIA patient, and a histiocytic sarcoma stage IV patient\u2010three case reports"],"prefix":"10.1111","volume":"124","author":[{"given":"P\u0113teris","family":"Alberts","sequence":"first","affiliation":[{"name":"International Virotherapy Center Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evija","family":"Olmane","sequence":"additional","affiliation":[{"name":"Department of Radiology Pauls Stradi\u0146\u0161 Clinical University Hospital Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linda","family":"Brok\u0101ne","sequence":"additional","affiliation":[{"name":"International Virotherapy Center Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zanda","family":"Krasti\u0146a","sequence":"additional","affiliation":[{"name":"Department of Radiology Pauls Stradi\u0146\u0161 Clinical University Hospital Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M\u0101ra","family":"Romanovska","sequence":"additional","affiliation":[{"name":"Department of Cytology Pauls Stradi\u0146\u0161 Clinical University Hospital Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K\u0101rlis","family":"Kup\u010ds","sequence":"additional","affiliation":[{"name":"Department of Radiology Pauls Stradi\u0146\u0161 Clinical University Hospital Riga Latvia"},{"name":"Department of Radiology Riga Stradi\u0146\u0161 University Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergejs","family":"Isajevs","sequence":"additional","affiliation":[{"name":"Department of Pathology Riga Eastern Clinical University Hospital Riga Latvia"},{"name":"Department of Pathology Faculty of Medicine University of Latvia Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guna","family":"Proboka","sequence":"additional","affiliation":[{"name":"Outpatient Department Riga Eastern Clinical University Hospital Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romualds","family":"Erdmanis","sequence":"additional","affiliation":[{"name":"ER Clinic Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jurijs","family":"Nazarovs","sequence":"additional","affiliation":[{"name":"Institute of Pathology Pauls Stradi\u0146\u0161 Clinical University Hospital Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dite","family":"Venskus","sequence":"additional","affiliation":[{"name":"International Virotherapy Center Riga Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,7,26]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fonc.2014.00188"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/nbt.2287"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/CMR.0000000000000180"},{"key":"e_1_2_6_5_1","first-page":"6","article-title":"Rigvir.
