Cytogenetically, congenital infantile fibrosarcoma is characterized by the majority of cases having a translocation between chromosomes 12 and 15 (notated as t(12;15)(p13;q25)) that results in formation of the fusion gene, ETV6-NTRK3, plus individual cases exhibiting trisomy for chromosomes 8, 11, 17, or 20.

Infantile digital fibromatosis, also termed inclusion body fibromatosis [10] or Reye tumor [11] Fibroma of tendon sheath [12] Desmoplastic fibroblastoma, also termed collagenous fibroma. [13] Mammary-type myofibroblastoma [14]
Retrospective reviews of patients treated for DFSP-FS find average 5-year recurrence-free survival rates of 42%-52% with a 10%-15% risk of having or developing metastatic disease. [13]
Survival rates for most childhood cancers have improved, with a notable improvement in acute lymphoblastic leukemia (the most common childhood cancer). Due to improved treatment, the 5-year survival rate for acute lymphoblastic leukemia has increased from less than 10% in the 1960s to about 90% during the time period 2003-2009.
The World Health Organization in 2020 classified the fibro sarcomatous DFSP (DFSP-FS) variant (also termed dermatofibrosarcoma protuberans, fibro sarcomatous) of the dermatofibrosarcoma protuberans as a specific form of the intermediate (rarely metastasizing) fibroblastic and myofibroblastic tumors and other variants of this disorder as a specific form of the intermediate (locally aggressive ...
In one review of 109 individuals with MFS: overall survival for the entire group was 80% at 3 years and 76% at 5 years; local recurrence-free survival was 95% at 3 years and 88% at 5 years; median survival following local recurrence was 68 months; distant metastasis-free survival was 78% at 3 and 77% at 5 years; and 18 of 25 patients (72%) died ...
Low-grade fibromyxoid sarcoma (LGFMS) is a rare type of low-grade sarcoma first described by H. L. Evans in 1987. [1] LGFMS are soft tissue tumors of the mesenchyme-derived connective tissues; on microscopic examination, they are found to be composed of spindle-shaped cells that resemble fibroblasts. [2]
The survival rate of children with cancer has improved since the late 1960s which is due to improved treatment and public health measures. The estimated proportion surviving 5 years from diagnosis increased from 77.8 percent to 82.7 percent to 85.4 percent for those diagnosed in the 1990s, 2000s, and 2010–2016.
