Sexual functioning after treatment for testicular cancer - Review and meta-analysis of 36 empirical studies between 1975-2000

Literature concerning sexual functioning after treatment for testicular cancer from 1975–2000 is reviewed. After a literature search in Medline and Psylit was conducted, as well as a search for cross-references made, a meta-analysis was performed. To describe sexual functioning, several aspects of the sexual response cycle were used: sexual desire, sexual arousal, erection, and orgasm; ejaculatory function, sexual activity, and sexual satisfaction were used as well. The number of patients included in the studies as well as treatment modalities were taken into account. A total of 36 relevant studies was screened (28 retrospective and 7 prospective studies), concerning 2,786 cases of testicular cancer. Meta-analysis revealed that ejaculatory dysfunction was reported most frequently and was related to surgery in the retroperitoneal area. Erectile dysfunction was related to irradiation, but was reported least frequently. Other sexual functions were not related to treatment modality. Meta-analysis revealed no deterioration of sexual functioning in the course of time, except a decrease in sexual desire and an increase in sexual satisfaction. Retrospective studies reported more sexual dysfunction than did prospective studies. Detailed analysis of separate studies, however, revealed a wide variation in reported sexual morbidity, as well as in assessment methods. Somatic consequences of disease and treatment may reduce ejaculation; however, other aspects of sexual functioning are not clearly related to disease- or treatment-related factors and may instead refer to a psychological vulnerability caused by ones confrontation with a life-threatening, genito-urinary disease, such as testicular cancer.

Sexual functioning after treatment for testicular cancer

This retrospective study evaluates changes in sexual functioning after treatment for testicular cancer and investigates whether there is a relationship with different treatment modalities.

Initial experience with identifying high-grade prostate cancer using diffusion-weighted MR imaging (DWI) in patients with a Gleason score </= 3 + 3 = 6 upon schematic TRUS-guided biopsy: a radical prostatectomy correlated series.

Introduction:Diffusion-weighted magnetic resonance (MR) imaging (DWI) might be able to fulfill the need to accurately identify high-grade prostate carcinoma, in patients initially selected for active surveillance in the Prostate Specific Antigen (PSA) screening era based on transrectal ultrasound-guided biopsy Gleason score. We aimed to determine whether DWI is able to correctly identify those patients with a biopsy Gleason score of ⩽3 + 3 = 6, but harboring Gleason 4 and/or 5 components in their radical prostatectomy (RP) specimen. Materials and Methods:Whole-mount RP specimens were used to identify regions of interest corresponding with tumor on the DWI-derived apparent diffusion coefficient (ADC) maps in 23 patients with a Gleason ⩽3 + 3 = 6 on biopsy. ADC values were correlated with RP Gleason grades. Statistical analysis was performed by calculating area under the receiver operating characteristic curve for identification of prostate cancer with Gleason 4 and/or 5 components using DWI, and Mann-Whitney U testing was performed to detect differences in median ADC values for tumors with presence of Gleason grade 4 and/or 5 versus a highest Gleason grade of ⩽3 on RP. Results:A diagnostic accuracy of median ADC values for identifying patients subject to transrectal ultrasound-guided biopsy undergrading with an area under the receiver operating characteristic curve of 0.88 was established using RP Gleason score as a reference. In patients harboring a Gleason 4 and/or 5 component, the median ADC was 0.86 × 10(−3) mm2/s (standard deviation ± 0.21), whereas patients harboring no Gleason 4 and/or 5 component displayed a median ADC of 1.16 × 10(−3) mm2/s (standard deviation ± 0.19) for the single tumor slice with the lowest median ADC (P < 0.002). Conclusions:DWI is able to predict the presence of high-grade tumor in patients with a Gleason ⩽3 + 3 = 6 on biopsy, providing important information for treatment decisions.

Current concepts about testicular cancer

In the past 20 years, testicular cancer, which occurs in the young, has become a curable malignancy; 90% of the patients treated will achieve long-term survival. However, there is a significant morbidity associated with the management of the disease process. The literature was reviewed concerning the current treatment strategies and prognosis, as well as the long-term sequelae of the various diagnostic and therapeutic procedures. Surveillance has become a key element in the management of patients with a primary (stage I) testicular non-seminoma. Although approximately 25% of these patients will relapse, 100% survival can be achieved with cisplatin in combination with etoposide and bleomycin (BEP). Patients with a disseminated non-seminoma are usually treated with 4 courses of BEP; an 80% survival rate can be achieved. The long-term effects of chemotherapy include Raynauds phenomenon, acral paraesthesia, hyperlipidaemia, nephrotoxicity, infertility and hormonal disturbances. Retroperitoneal lymph node dissection or resection of residual disease following chemotherapy are associated with a low mortality and morbidity rate, ejaculatory dysfunction excepted. However, with specific modifications in technique (e.g. nerve-sparing) antegrade ejaculation can be preserved in the majority of patients. Radiotherapy is used in stage I and II seminoma. With the conventional dose of 25–30 Gy to the retroperitoneal and ipsilateral iliac lymph nodes, temporary dysfunction of the germ and Leydig cells of the remaining testis may occur by scatter radiation. Patients with advanced seminoma are treated with cisplatin-based chemotherapy. To date, testicular cancer patients can receive appropriate curative treatment with acceptable acute toxicity, depending on the therapy given. The detrimental effects of late toxicities require careful study and follow-up. However, little attention is paid currently to quality of life aspects, in particular the impact of the disease and its treatment on general well-being, including sexual function.

Impact of Obesity on Surgical Outcomes following Open Radical Prostatectomy

Objective: The increasing incidence of both obesity and prostate cancer (PCa) detection will confront the urologist more often with obese men having PCa. It is unknown whether obesity affects the surgical and oncological outcomes following open radical retropubic prostatectomy (RRP). Knowledge concerning this issue is relevant when counselling obese patients with PCa for RRP. Patients and Methods: A single institution cohort study was performed including 252 men who underwent a RRP between 1992 and 2003. The surgical complications (perioperative complications, post-RRP urinary incontinence, urethral strictures) were compared between obese (BMI >30) and nonobese (BMI ≤30) men. Results: Compared to nonobese (n = 221), obese men (n = 31) developed more frequently wound infections (16.1 vs. 4.5%; p < 0.05), urinary incontinence (25.8 vs. 8.7%; p < 0.05) as well as vesico-urethral strictures (46.2 vs. 12.3%; p < 0.05). The pathology results and the 5-year cumulative risk of PSA recurrence were comparable among both groups. Conclusions: Compared to nonobese, obese men suffer more frequently from post-RRP urinary incontinence and vesicourethral strictures following open RRP.

Sexual dysfunction in nonseminoma testicular cancer patients is related to chemotherapy-induced angiopathy.

PURPOSE To establish the prevalence of sexual dysfunctions after different treatment modalities for nonseminomatous testicular germ cell tumor (NSTGCT) and to investigate whether treatment-induced angiopathy and neuropathy is related to sexual dysfunction. PATIENTS AND METHODS A questionnaire assessing sexual dysfunction was sent to 255 NSTGCT survivors. Polychemotherapy (PCT) regimens (cisplatin, vinblastine, and bleomycin [PVB], vinblastine substituted by etoposide [BEP], or cisplatin substituted by carboplatin [CEB], etoposide combined with cisplatin [EP], or with ifosfamide and cisplatin [VIP] were compared regarding treatment-induced angiopathy and neuropathy. Sexual dysfunctions were related to Raynauds phenomenon and acral paresthesia. RESULTS Among the 215 responders, 56 (26%) had been treated by orchidectomy and surveillance, 42 (19.6%) by PCT, and 117 (54.4%) by PCT and resection of residual retroperitoneal tumor mass (RRRTM). Overall, loss of libido was reported by 19.1%, decreased arousal by 11.2%, erectile dysfunction by 12.1%, decreased intensity of orgasm by 20%, and ejaculatory problems by 28%. Patients treated with PVB suffered more often from Raynauds phenomenon compared with those treated with other regimens (40.4% v 29%; P < .05) and from paresthesia (31.6% v 14.7%; P < .05). Patients with Raynauds phenomenon had more often erectile dysfunction (28.8%) compared with those without (8.4%) (P < .05). CONCLUSION Compared with orchidectomy alone, PCT, with or without RRRTM, induced more often posttreatment sexual dysfunction. Compared with other chemotherapeutic regimens, signs of angiopathy and neuropathy were most prevalent in those treated with PVB. Erectile dysfunction was related to the chemotherapy-induced Raynauds phenomenon but not to acral paresthesia.

The sexual sequelae of testicular cancer.

Malignant tumours of the thestis are mainly found in the third and fourth decade of life, a period in wich most men are highly sexually active. Although post-treatment sexual funtioning is a very relevant aspect of the quality of life, only a very small amount of information is available about the sexual sequelae of the current therapies for testicular cancer. In this thesis, the impact of the different treatment modalities on organ systems important for normal sexual functioning was studied. ... Zie: Summary

Sexual functioning after multimodality treatment for disseminated nonseminomatous testicular germ cell tumor

PURPOSE We determined sexual functioning after chemotherapy for disseminated nonseminomatous testicular germ cell tumor, and evaluated the impact of resection of post-chemotherapy residual retroperitoneal tumor. MATERIALS AND METHODS A total of 155 consecutive patients treated with chemotherapy for disseminated nonseminomatous testicular germ cell tumor (between 1980 and 1994) was questioned about their sexual functioning. The patients were divided in 2 subgroups: patients treated with or without resection of post-chemotherapy residual retroperitoneal tumor. Volume and location (divided into left para-aortal or right paracaval/interaortacaval) of the resected tumor were related to absence of ejaculation as well as decreased semen amount. In addition, libido, arousal, erection and orgasm were related to ejaculatory dysfunction. RESULTS A total of 43 patients (27.7%) was treated with chemotherapy only and 112 (72.3%) had additional resection of post-chemotherapy residual retroperitoneal tumor mass. Overall, 22.4% reported loss of libido, 14.1% decreased arousal, 16% erectile dysfunction, 23.1% decreased orgasmic intensity, 17.4% decreased semen amount and 18.7% complete absence of antegrade ejaculation. With exception of absence of ejaculation, sexual dysfunctions were reported in similar frequencies in both treatment subgroups. In the resection of post-chemotherapy residual retroperitoneal tumor subgroup, 25.9% of the patients had complete absence of ejaculation. The other sexual dysfunctions were related neither to decreased semen amount nor to complete absence of ejaculation. The mean volume of resected tumor was higher (95 cm.3) in patients with absence of ejaculation than in those without (40 cm.3), and patients with right paracaval/interaortacaval tumor (20 of 58, 34.5%) reported more often absence of ejaculation than those with left para-aortal tumor (9 of 54, 16.7%). CONCLUSIONS In patients treated for disseminated nonseminomatous testicular germ cell tumor, post-chemotherapy sexual morbidity cannot be neglected. Except for loss of antegrade ejaculation, sexual dysfunctions are not related to resection of post-chemotherapy residual retroperitoneal mass. A high volume of tumor and a right paracaval/interaortacaval location predispose to loss of antegrade ejaculation.

Pathologische karakteristieken van het radicale prostatectomiepreparaat bij kandidaten voor active surveillance

Introductie De selectie van patiënten met een laagrisicoprostaatcarcinoom (PCa) voor active surveillance (AS) is gebaseerd op klinisch stadium, PSA en TRUS-geleide biopsiecriteria. Grootste beperking van een dergelijke benadering is de potentiële onderschatting van de werkelijke gecombineerde gleasonscore en het pathologisch stadium. Doel van onze serie is te evalueren in hoeverre de pathologie bij radicale prostatectomie (RP) bij kandidaten voor AS overeenkomt met de preoperatieve klinische en pathologische stadiëring.
