Radiotherapy in testicular germ cell tumours - a literature review.

Testicular germ cell tumours (GCT) represent about 1-2% of malignant in men. The essential therapeutic option for early-stage GCT is radical orchiectomy (RO), except in situations that require immediate chemotherapy in patients with a massive dissemination and unequivocally elevated levels of tumour markers. Postoperative radiotherapy (PORT) in patients with testicular seminoma in Clinical Stage I (CS I) is one of the treatment options next to active surveillance (AS) and chemotherapy (CHTH). Regardless of the procedure, five-year survival in this group of patients ranges between 97% and 100%. In the article, we present the literature review pertinent to therapeutic options, with a focus on radiotherapy. We have searched MEDLINE (PubMed) for all studies on patients with GCT treated with radiation therapy during the last 20 years, and the current therapeutic recommendations. We used the following keywords: germ cell tumours, testis, seminoma, non-seminoma, radiotherapy, outcome.

Primary penile cancer organ sparing treatment.

INTRODUCTION: Surgical treatment of penile cancer is usually associated with mutilation; alterations in self-esteem and body image; affecting sexual and urinary functions; and declined health-related quality of life. Recently, organ sparing treatment has appeared and led to limiting these complications. MATERIAL AND METHODS: An extensive review of the literature concerning penile-preserving strategies was conducted. The focus was put on indications, general principles of management, surgical options and reconstructive techniques, the most common complications, as well as functional and oncological outcomes. RESULTS: Analyzed methods, e.g.: topical chemotherapy, laser ablation therapy, radiotherapy, Moh's microscopic surgery, circumcision, wide local excision, glans resurfacing and glansectomy are indicated in low-stage tumors (Tis, Ta-T2). After glansectomy, reconstruction is also possible. CONCLUSIONS: Organ sparing techniques may achieve good anatomical, functional, and psychological outcomes without compromising local cancer control, which depends on early diagnosis and treatment. Penile sparing strategies are acceptable treatment approaches in selected patients with low-stage penile cancer after establishing disease-risk and should be considered in this population.

Usefulness of Somatostatin Receptor Scintigraphy (Tc-[HYNIC, Tyr3]-Octreotide) and 123I-Metaiodobenzylguanidine Scintigraphy in Patients with SDHx Gene-Related Pheochromocytomas and Paragangliomas Detected by Computed Tomography.

AIMS: The aim of this study was to assess the usefulness of somatostatin receptor scintigraphy (SRS) using (99m)Tc-[HYNIC, Tyr3]-octreotide (TOC) and 123I-metaiodobenzylguanidine (mIBG) in patients with SDHx-related syndromes in which paragangliomas were detected by computed tomography and to establish an optimal imaging diagnostic algorithm in SDHx mutation carriers. METHODS: All carriers with clinical and radiological findings suggesting paragangliomas were screened by SRS and 123I-mIBG. Lesions were classified by body regions, i.e. head and neck, chest, abdomen with pelvis and adrenal gland as well as metastasis. RESULTS: We evaluated 46 SDHx gene mutation carriers (32 index cases and 14 relatives; 28 SDHD, 16 SDHB and 2 SDHC). In this group, 102 benign tumors were found in 39 studied patients, and malignant disease was diagnosed in 7 patients. In benign tumors, the sensitivity of SRS was estimated at 77% and of 123I-mIBG at 22.0%. The SRS and mIBG sensitivity was found to be clearly region dependent (p < 0.001). The highest SRS sensitivity was found in head and neck paragangliomas (HNP; 91.4%) and the lowest was found in abdominal paragangliomas and pheochromocytomas (40 and 42.9%, respectively). The highest 123I-mIBG sensitivity was found in pheochromocytomas (sensitivity of 100%) and the lowest in HNP (sensitivity of 3.7%). In metastatic disease, SRS was superior to mIBG (sensitivity of 95.2 vs. 23.8%, respectively). CONCLUSION: SRS and 123I-mIBG single photon emission computed tomography (SPECT) sensitivity in SDHx patients is highly body region dependent. In malignant tumors, SRS is superior to 123I-mIBG SPECT.

Treatment of stage I seminoma: 25 years of experience.

AIM OF THE STUDY: To review management and outcomes in patients with stage I seminoma after orchidectomy. MATERIAL AND METHODS: Between 1979 and 2004 a total 292 patients with stage I seminoma were treated with adjuvant chemotherapy or radiotherapy or were placed on surveillance. Median age at diagnosis was 36 years (range 20-69), with median follow-up 76.5 months (range 11-294). Of the patients, 200 (68.5%) were treated with adjuvant chemotherapy, 72 (24.6%) were irradiated and 20 (6.8%) were placed on surveillance. RESULTS: The probability of 5-year overall survival and relapse-free survival for the entire group was 100% and 95.1% respectively. The 5-year relapse-free survival for adjuvant chemotherapy was 97.2%, for radiotherapy 94.6%, and 31.4% for the surveillance group. Of 24 (8.4%) patients who had relapse in lymph nodes and/or internal organs, 14/20 patients were in the surveillance group. All patients who had a relapse were salvaged successfully with chemotherapy. The toxicity of chemotherapy and radiotherapy was acceptable. No severe reactions were observed. CONCLUSION: Our results confirm the excellent prognosis for patients with stage I seminoma after orchidectomy treated with adjuvant chemotherapy or radiotherapy. The high rate of relapse in our surveillance group suggests the necessity of adjuvant treatment.

Urinary incontinence after radical prostatectomy - experience of the last 100 cases.

Radical prostatectomy (RP) is a recognized treatment method of organ-confined prostate cancer. Among post-surgery complications, urinary incontinence is a major one. The aim of this study was to determine the incontinence rate after RP and to analyze factors that might affect it. Between March 2007 and December 2008, 132 RP's were performed at Warsaw Cancer Center. A questionnaire to assess the condition before and after RP was developed by the authors and sent to all treated patients. The questionnaire focused on health status information, function in urinary domain, rate of returning to "normal" activity level as before RP and satisfaction from the treatment. The median age of patients was 62 years. Out of 132 patients 102 subjects (77.2%) responded to the questionnaire. Of all responders, 35 patients (34.3%) reported total urinary continence after RP. After RP 35(34.3%) patients reported total urinary continence and in 55(53.9%) patients urinary incontinence of medium degree was present. In 12 (11.8%) patients significant urinary incontinence developed. The most common cause of urine dripping (82% of patients with any degree of urinary incontinence) was associated with abdominal muscle pressure. No statistically significant association between urinary incontinence and adjuvant radiotherapy after RP or the surgeon performing the RP was found (>0.79, >0.803). Radical prostatectomy carries a certain risk of complications. We observed an 88.2% rate of significant (total and moderate degree) urinary continence. The adjuvant radiotherapy and surgeons, who performed the RP, did not affect the rate of incontinence.
