Neoadjuvant chemotherapy (NAC) has shown promising results in patients with locally advanced penile cancer. However, no consensus exists on its applications for locally advanced penile cancer. Thus, it is unclear which kind of chemotherapy regimen is the best choice. Consequently, a systematic search of PubMed, Web of Science, and EMBASE was performed in March 2021 to assess the efficacy and safety of NAC for the treatment of patients with locally advanced penile cancer. The Newcastle-Ottawa Scale was used to assess the risk of bias in each study. This study synthesized 14 published studies. The study revealed that patients who achieved an objective response to NAC obtained a better survival outcome compared with those who did not achieve an objective response. In addition, the objective response rates (ORRs) and pathological complete response (pCR) rates were 0.57 and 0.11, respectively. The incidence of grade ≥3 toxicity was 0.36. Subgroup analysis found that the ORR and pCR of the taxane-platinum (TP) regimen group performed better than those of the nontaxane-platinum (NTP) regimen group (0.57 vs 0.54 and 0.14 vs 0.07, respectively). Moreover, the TP regimen group had more frequent toxicity than the NTP regimen group (0.41 vs 0.26). However, further studies were warranted to confirm the findings.

Objective: We aim to evaluate the morbidity and mortality of cancer attributable to human papillomavirus (HPV) infection in China in 2016. Methods: Based on the cancer incidence and mortality rates, national population data, and population attributable fraction (PAF) in China, we calculated the number of incidence and death cases attributed to HPV infection in different areas, age groups, and gender in China in 2016. The standardized incidence and mortality rates for cancer attributed to HPV infection were calculated by using Segi's population. Results: In 2016, a total of 124 772 new cancer cases (6.32 per 100 000) were attributed to HPV infection in China, including 117 118 cases in women and 7 654 cases in men. Of these cancers, cervical cancer was the most common one, followed by anal cancer, oropharyngeal cancer, penile cancer, vaginal cancer, laryngeal cancer, oral cancer, and vulvar cancer. A total of 41 282 (2.03 per 100 000) deaths were attributed to HPV infection, of which 37 417 occurred in women and 3 865 in men. Most deaths were caused by cervical cancer, followed by anal cancer, oropharyngeal cancer, penile cancer, laryngeal cancer, vaginal cancer, oral cancer, and vulvar cancer. The incidence and mortality rates of cervical cancer increased rapidly with age, peaked in age group 50-54 years, then decreased obviously. The morbidity and mortality rates of non-cervical cancer increased with age. The cancer case and death numbers in rural areas (57 089 cases and 19 485 deaths) were lower than those in urban areas (67 683 cases and 21 797 deaths). However, the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of cervical cancer were higher in rural areas than in urban areas. There were no significant differences in ASIR and ASMR of non-cervical cancers between urban areas and rural areas. Conclusions: The incidence of cancers attributed to HPV infection in China was lower than the global average, but the number of incidences accounted largely, furthermore there is an increasing trend of morbidity and mortality. The preventions and controls of cervical cancer and male anal cancer are essential to contain the increases in cancer cases and deaths attributed to HPV infection.

Cavernous nerve injury is an important cause of erectile dysfunction (ED). Although protective nerve technology has been widely used in nerve-sparing radical prostatectomy (nsRP), the incidence of ED is still very high after surgery. The purpose of our study was to evaluate erectile function (EF) and penile length in the non-erectile state (PLNES) following scheduled phosphodiesterase 5 inhibitor (PDE5i), vacuum erectile device (VED) treatment, and combination therapy after nsRP. One hundred patients with localized prostate cancer and normal EF were randomized to scheduled PDE5i group, VED treatment group, a combined treatment group, and the control group without any intervention. The International Index of Erectile Function-5 (IIEF-5) scores and PLNES were evaluated after 6 months and 12 months of treatment. Sexual Encounter Profile (SEP-Question 2 and SEP-Question 3) were evaluated after 12 months of treatment. Ninety-one of the 100 randomized patients completed the study. We found that the 5 mg tadalafil once a day (OaD) combined with VED can help improve IIEF-5 scores in nsRP patients after both 6 months and 12 months. VED alone or combined with tadalafil OaD can help patients maintain PLNES. VED combined with tadalafil OaD can improve the rate of successful penetration (SEP-Question 2) after 12 months. There were no significant differences in the return to target EF after 12 months among the groups. No significant correlation was noted between the variables and return to target EF (IIEF ≥ 17), and between the variables and effective shortening of the patient's penis (shortening ≥ 1 cm) after 12 months of intervention.

This study aimed to investigate the curative effect of spiral embedded flap urethroplasty for the treatment of meatal stenosis after penile carcinoma surgery. From January 2015 to January 2021, we used our technique to treat strictures of the external urethral orifice in seven patients, including four cases of meatal stenosis after partial penile resection and three cases of meatal stenosis after perineal stoma. All patients had previously undergone repeat urethral dilatation. The patients underwent spiral embedded flap urethroplasty to enlarge the outer urethral opening. The patients' mean age at the time of surgery was 60 (range: 42-71) years, the mean operative time was 43 min, and the median follow-up period was 18 months. The patients voided well post-operatively, and urinary peak flow rates ranged from 18.3 ml s^-1 to 30.4 ml s^-1. All patients were successful with absence of urethral meatus stricture. The present study showed that using spiral embedded flap urethroplasty to treat meatal stenosis after penile carcinoma surgery is an effective surgical technique with good long-term outcomes.

With the onset of a metabolic syndrome epidemic and the increasing life expectancy, erectile dysfunction (ED) has become a more common condition. As incidence and prevalence increase, the medical field is focused on providing more appropriate therapies. It is common knowledge that ED is a chronic condition that is also associated with a myriad of other disorders. Conditions such as aging, diabetes mellitus, hypertension, obesity, prostatic hypertrophy, and prostate cancer, among others, have a direct implication on the onset and progression of ED. Characterization and recognition of risk factors may help clinicians recognize and properly treat patients suffering from ED. One of the most reliable treatments for ED is penile prosthetic surgery. Since the introduction of the penile prosthesis (PP) in the early seventies, this surgical procedure has improved the lives of thousands of men, with reliable and satisfactory results. The aim of this review article is to characterize the epidemiology of men undergoing penile prosthetic surgery, with a discussion about the most common conditions involved in the development of ED, and that ultimately drive patients into electing to undergo PP placement.

Human papillomavirus (HPV) infection appears to play an important role in the development of penile cancer (PeCa), but their relationship remains unclear. Therefore, we performed a systematic review and meta-analysis to elucidate their relationship. We systematically searched Embase, PubMed, Cochrane Library, and Web of Science for case-control studies and cross-sectional studies using polymerase chain reaction (PCR) technology on formalin-fixed paraffin-embedded (FFPE) or paraffin-embedded (PE) PeCa tissues to detect HPV (published between January 1, 2007, and December 29, 2017; no language restrictions). Twenty-two studies were identified, and 1664 cases were available for analysis. The combined HPV infectious risk of PeCa is 51.0% (95% confidence interval [CI]: 43.0%-60.0%). The three most common subtypes of HPV were HPV16 (28.5%), HPV18 (2.3%), and HPV6 (2.3%). The virus was relevantly associated with basaloid (85.5%, 95% CI: 77.2%-93.8%) and warty (50.0%, 95% CI: 35.2%-64.8%) carcinomas. The invasiveness of PeCa was not associated with HPV (χ^[2] = 0.181, df = 1, P < 0.671). HPV infection in PeCa tended to be moderately differentiated (54.4%, 95% CI: 47.7%-61.1%). This study found that almost half of PeCa patients are associated with HPV. The most commonly associated genotype is HPV16, but several other genotypes were also detected. In addition to types 6 and 11, other single low-risk HPV infections have been found to contribute to PeCa to a lesser degree. HPV-positive tumors tend to exhibit warty and/or basaloid features, corresponding to a moderate histological grade. The role of HPV in PeCa should be revisited to provide evidence for the development of PeCa in the presence of HPV infection.

ObjectiveHuman papilloma virus (HPV) is a necessary cause of cervical cancer and is also closely related to penile cancer, oropharyngeal cancer, and anal cancer in males. However, few studies are reported on male HPV. This study aimed to investigate HPV infection of the external genitalia in men whose female partners have cervical HPV infection.

METHODSWe collected the relevant data on the male outpatients whose partners had cervical HPV infection in our Department of Urology and Andrology from August to December 2016. We obtained samples with nylon swabs from the glans penis, corona, inner layer of the prepuce and penile body and detected different types of HPV infection using the Hybribio HPV typing kit, PCR and membrane hybridization.

RESULTSValid data were collected from 140 males, which showed 83.5% of HPV infection of the external genitalia, including 60 cases of HPV6 (43.2%), 27 cases of HPV16 (19.4%), 14 cases of HPV39 (10.1%), 13 cases of HPV18 (9.4%), 13 cases of HPV58 (9.4%), and 13 cases of HPV52 (9.4%). Redundant prepuce was found in 75.5% of the males, but there was no statistically significant difference in the incidence rate of HPV infection between the normal and redundant prepuce groups (P > 0.05).

CONCLUSIONSMen who have the female partners with positive cervical HPV are at high risk of HPV infection and therefore need to be screened and treated so as to reduce HPV infection in both sexes.

ObjectiveTo evaluate the two newly established nomograms for predicting lymph node metastasis in penile cancer based on the clinical data on a large cohort of patients.

METHODSWe retrospectively studied the clinical data on 93 patients with penile cancer treated in the Center for Tumor Prevention and Treatment. Using the two recently established nomograms (Bhagat nomogram and Zhu nomogram), we predicted lymph node metastasis in the patients, analyzed the differences between prediction and the results of postoperative pathology, and compared the accuracy of prediction between the two nomograms with the receiver operating characteristic (ROC) curve and the area under the curve (AUC).

RESULTSThe median age of the patients was 55 (27－82) years. Positive lymph nodes were found in 31 cases (33.3%) postoperatively and in 9 (21.9%) of the 41 clinically negative cases. The AUC of the Bhagat nomogram was 0.739 and that of Zhu nomogram was 0.808, both of which were similar to the prediction accuracy of internal verification and manifested a medium predictive ability.

CONCLUSIONSThe newly established Bhagat and Zhu nomograms can be used for predicting lymph node metastasis in penile cancer, but with a low precision, and therefore cannot be relied exclusively for the option of inguinal lymphadenectomy.

PURPOSE: There are many grey areas in the field of penile rehabilitation after radical prostatectomy (RP). The preservation of the full dimensions of the penis is an important consideration for improving patients' compliance for the treatment. We present the first case series of patients treated by laparoscopic extraperitoneal RP and simultaneous penile prosthesis implantation (PPI) in order to preserve the full length of the penis and to improve patients' satisfaction. MATERIALS AND METHODS: From June 2013 to June 2014, 10 patients underwent simultaneous PPI (with an AMS InhibiZone prosthesis) and RP. Patients were evaluated by means of urological visits, questionnaires, and objective measurements before surgery, at discharge from the hospital, on postoperative days 21 to 28, each 3 months for the first year, and each 6 months thereafter. The main outcome measures were biochemical recurrence-free rate, penile length, and quality of life. RESULTS: Ten patients (mean age of 61 years; completed the study follow-up period (median, 32.2 months). No difference was found between the time of surgery and the 2-year follow-up evaluation in terms of penile length. The pre-surgery 36-Item Short Form Health Survey (SF-36) median score was 97. Patients were satisfied with their penile implants, and couples' level of sexual satisfaction was rated median 8. The median postoperative SF-36 score was 99 at 3 months follow-up. CONCLUSIONS: Laparoscopic extraperitoneal RP surgery with simultaneous PPI placement seems to be an interesting possibility to propose to motivated patients for preserving the length of the penis and improving their satisfaction.
