Bertoncelli Tanaka M, Sahota K, Burn J, Falconer A, Winkler M, Ahmed HU, Rashid TG. Prostate cancer in transgender women: what does a urologist need to know? BJU Int 2021; 129:113-122. [PMID: 34157213 DOI: 10.1111/bju.15521] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 04/29/2021] [Accepted: 06/18/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To review of the existing literature, current guidelines and standard of practice related to prostate cancer in transgender women, as the transgender population share many of the same healthcare needs as their cisgender counterparts, but may have additional specialist needs. MATERIALS AND METHODS We performed a non-systematic review of the literature, current guidelines and standard of practice related to prostate cancer in transgender women. RESULTS Our search revealed 10 case reports of prostate cancer in transgender women, four specialist opinion papers, six cohort studies, and four systematic reviews. The information in these publications were assimilated to produce a review of prostate cancer in transgender women. CONCLUSION The risk of prostate cancer in transgender women who are not on gender-affirming hormone therapy (GAHT) or who have not had gender-affirming surgery (GAS) and gender non-conforming individuals (who may never commence GAHT or have GAS) is the same as that in the cis male population. In these patients, healthcare professionals need to be able to discuss screening, diagnostic and treatment options considering future wishes for gender-affirming treatment. Prostate cancer incidence in transgender women on GAHT or following GAS is lower than age-matched cis-male counterparts, but diagnosis and treatment is more nuanced. The present review discusses the existing literature about development and incidence of prostate cancer in this population, and makes recommendations about screening, the usefulness of diagnostic tools e.g. prostate-specific antigen and magnetic resonance imaging, and considerations when formulating treatment. Potential directions for future research are discussed, which will hopefully lead to development of robust evidence-based guidelines for the diagnosis and management of prostate cancer in transgender women.

A Review of the Literature on Primary Leiomyosarcoma of the Prostate Gland. Adv Urol 2015; 2015:485786. [PMID: 26640482 PMCID: PMC4659954 DOI: 10.1155/2015/485786] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2015] [Revised: 09/24/2015] [Accepted: 10/04/2015] [Indexed: 12/20/2022] Open
Abstract
Primary leiomyosarcoma of the prostate (PLSOP) is rare, with less than 200 cases reported so far. PLSOPs present with lower urinary tract symptoms, haematuria, and perineal pain; may or may not be associated with a history of previous treatment for adenocarcinoma of prostate by means of radiotherapy and or hormonal treatment; may afflict children and adult male. Examination may reveal benign enlarged prostate and hard enlarged mass. PLSOPs may be diagnosed by histological examination findings of spindle-shaped carcinoma cells in prostate specimens. Immunohistochemical staining tends to be positive for vimentin, CD44, smooth muscle actin, and calponin, focally positive for desmin, and at times positive for keratin. They stain negatively for PSA, S-100, CD34, CD117, and cytokeratin. Cytogenetic study on primary leiomyosarcoma of the prostate gland may show clonal chromosomal rearrangement involving Chromosomes 2, 3, 9, 11, and 19. On the whole the prognosis is poor. Surgery with or without chemotherapy would appear to be the mainstay of treatment for PLSOPs that are operable, but generally there is no consensus opinion on the best therapeutic approach. Most cases of PLSOPs are diagnosed in an advanced stage of the disease. A global multicenter trial is required to find therapies that would improve the prognosis.

Abstract
High-energy external radiotherapy has become one of the most common treatment in localized prostate cancer. We compared the difference of dose distribution, mainly at the 5-30 Gy dose level, in the irradiated pelvic volume among three modalities of radiotherapy for patients with prostate cancer: conventional, conformal and intensity-modulated radiotherapy (IMRT). We selected six patients with prostate cancer treated by conformal radiotherapy at the doses of 46 Gy to PTVN (prostate and seminal vesicles), and 70 Gy to PTV-T (prostate). The conventional technique": an 8-field arrangement was used; the conformal technique 4 fields with a boost through 6 fields. For IMRT, a five-beam arrangement was used. Dose-volume histograms (DVH) were analyzed and compared among the three techniques. The IMRT technique significantly increased the pelvic volume covered by the isodose surfaces below 15 Gy as compared with the conventional and conformal techniques. The mean absolute increase for the pelvic volume included between 5-30 Gy for the IMRT technique, was about 2 900 ml as compared with the conventional technique. However, IMRT significantly reduced the irradiated volume of the rectum in the dose range of 5 to 40 Gy, also significantly reduced the irradiated volume of bladder and femoral heads, and obtained a similar or improved isodose distribution in the PTVs. In addition, the use of IMRT slightly increased the relative dose delivered to the body volume outside the pelvis, as estimated by the use of specific software. A long-term follow-up will be needed to evaluate potential late treatment complications related to the use of IMRT and the low or moderate irradiation dose level obtained in the pelvis and in the whole body.

Abstract
While dose escalation is proving important to achieve satisfactory long-term outcomes in prostate cancer, the optimal radiation modality to deliver the treatment is still a topic of debate. Charged particle beams can offer improved dose distributions to the target volume as compared to conventional 3D-conformal radiotherapy, with better sparing of surrounding healthy tissues. Exquisite dose distributions, with the fulfillment of dose-volume constraints to normal tissues, however, can also be achieved with photon-based intensity-modulated techniques. This review summarizes the literature on the use of particle therapy in prostate cancer and attempts to put in perspective its relative merits compared to current photon-based radiotherapy.
