Abstract
OSPINO-PENA, Rosalba et al. Case report: Prostate squamous cell carcinoma managed with an external intensity-modulated radiotherapy technique. rev.colomb.cancerol. [online]. 2017, vol.21, n.2, pp.126-129. ISSN 0123-9015. https://doi.org/10.1016/j.rccan.2016.04.005.
The incidence of squamous cell carcinoma of prostate is between 0.5-1% of all neoplastic lesions of this gland.
Due to their rarity, there are no protocolised recommendations on the management of these patients. A report is presented on a patient with this diagnosis treated at our institution, its outcome at two years of follow-up, and a review of the subject.
Case report:
Male patient, 79 years old, diagnosed with invasive squamous cell carcinoma of the prostate. Staged as T4NxMx/IPSA 2.64/Gleason undeterminable. Work up studies were negative, and primaries from nearby organs were ruled out.
He was treated with radiotherapy as monotherapy and was scheduled for an intensity-modulated radiotherapy (IMRT) technique, initially to the pelvis at a radiotherapy dose of 46 Gy 2Gy daily (PTV 1), further reinforcing prostate and vesicles up to 56 Gy (1.1 PTV), and finally to 76 Gy to prostate (PTV 1,1,1).
With a follow-up of two years, lung lesions were found, which were biopsied and positive for squamous cell carcinoma.
