Retroperitoneal DDL is the most common, surgically unaccessible and serious form of DDL: it has a recurrence rate of 66% and a five-year overall survival rate of 54%. [31] The primary treatment option for retroperitoneal DDL is surgical resection.
Pediatric rhabdomyosarcoma patients have a 50–85% long term survival rate. [23] Osteosarcoma is a cancer of the bone that is treated with surgical resection of as much of the cancer as possible, often along with chemotherapy. [24] Radiotherapy is a second alternative to surgery, although not as successful.
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.
Post-treatment local recurrences and metastases were observed in 15% and 38% of cases; 5- and 10-year overall survival rates were 60% and 48%, respectively; Overall median survival time were 10.1 years; and patients with tumors ≥10 cm in longest diameter had an almost 6-fold higher rate of developing metastases than patients with tumors 4 cm ...
Desmoplastic small-round-cell tumor (DSRCT) is an aggressive and rare cancer that primarily occurs as masses in the abdomen. [4] Other areas affected may include the lymph nodes, the lining of the abdomen, diaphragm, spleen, liver, chest wall, skull, spinal cord, large intestine, small intestine, bladder, brain, lungs, testicles, ovaries, and the pelvis.
A leiomyosarcoma (LMS) is a rare malignant (cancerous) smooth muscle tumor. [1] The word is from leio- 'smooth' myo- 'muscle' and sarcoma 'tumor of connective tissue'. The stomach, bladder, uterus, blood vessels, and intestines are examples of hollow organs made up of smooth muscles where LMS can be located; however, the uterus and abdomen are the most common sites.
The retroperitoneal space (retroperitoneum) is the anatomical space ... The most common type is a sarcoma followed by lymphoma, extragonadal germ cell tumor, ...
Patients may experience issues including anxiety, fatigue, or trouble sleeping; despite the increased survival rate, their level of emotional distress has been compared to that of cancer patients, including "patients with sarcoma, also a malignant connective tissue disorder".
