Figures 2 Full Text Over the last few decades, multidisciplinary treatment of cancer patients has improved survival rates and the disease-free periods.
However, the number of tumors associated with treatment, particularly radiotherapy, has also increased. Its justification is based on the concept of oncogenesis due to radiation, established by Cahan et al.
Their only controversial point is the time necessary for cancer to be associated with radiotherapy. The original criteria stated 5 years, but it has currently been shown that the period can be shorter, with the appearance of radiation-induced tumors from 6 months to 20 years after treatment completion.
However, this is not yet conclusive in humans.

Their mechanisms include abnormal intracellular signaling, cytokine production, the creation of free radicals, and the secondary triggering of an inflammatory response.
She had complete response and was kept under surveillance.
Eight years later, with no apparent recurrence, the patient presented with rectal tenesmus associated with rectal bleeding. The diagnosis was high-grade leiomyosarcoma.

Nuclear magnetic resonance NMR imaging corroborated the dependence on the rectal wall, as well as the involvement of the muscles of the perineum and the fat of both buttocks in the anal region fig.
The rest of the extension studies were negative for distant disease.
The multidisciplinary team began treating the patient with induction CT doxorubicin and gemcitabine , after performing a sigmoid loop diversion colostomy. Response to the third CT cycle was partial and total pelvic exenteration with vulvectomy was indicated.
Intraoperative findings were a tumor in the perineal region involving the gluteus maximus and levator ani muscles, with no separating plane of the uterus and bladder. Urinary reconstruction through ileal conduit and diversion colostomy was performed.
The patient had adequate progression with no complications.
Surgical specimen examination corroborated the differentiation to high-grade smooth muscle tumor. Nevertheless, metastasis may develop after a long tumor-free interval.
The disease-free interval for the present case was 26 years, which was, to the best of our knowledge, the longest reported so far.
Dios et al. The reason why these tumors have such a long free-disease interval remains uncertain and should be investigated. As suggested by this report, a long-term follow-up is necessary in the case of ULMS.
A high level of suspicion of lung metastasis is essential when a pulmonary lesion is detected, despite the fact that such situations are so rare. Ethical disclosuresProtection of human and animal subjects The authors declare that no experiments were performed on humans or animals for this study.

While older adult patients often develop sarcomas with complex genetic karyotypes, there are relatively few genetic mutations driving tumorigenesis for the majority of childhood sarcomas, with the exception of some characteristic chromosomal translocations. Not more than cases are reported in the literature and there is still no solid association between rectal leiomyosarcoma and pelvic radiation.
