ABSTRACT

ABSTRACT Purpose: To determine independent predictors of inguinal lymph node (ILN) metastasis in patients with penile cancer. Patients and methods: We retrospectively analyzed all patients with penile cancer who underwent surgery at our medical center in the last ten years (n=157). Using univariate and multivariate logistic-regression models, we assessed associations with age, medical-history, phimosis, onset-time, number and maximum diameter of involved ILNs measured by imaging, pathological T stage, degree of tumor differentiation and/or cornification, lymphatic vascular infiltration (LVI), nerve infiltration, and ILN metastases. Interaction and stratified analyses were used to assess age, phimosis, onset time, number of ILNs, cornification, and nerve infiltration. Results: A total of 110 patients were included in the study. Multiple logistic regression analysis showed that the following factors were significantly correlated with ILN metastasis: maximum diameter of enlarged ILNs, T stage, pathological differentiation, and LVI. Among patients with a maximum ILN diameter ≥1.5cm, 50% had lymph node metastasis whereas 30.6% patients with a maximum ILN diameter <1.5cm showed LNM. Among 44 patients with stage Ta/T1, 10 showed ILN metastases, while 47.0% patients with stage T2 showed ILN metastases. Among 40 patients with highly differentiated penile-cancer, eight showed ILN metastasis, while 47.1% patients with low-to-middle differentiation showed ILN metastases. The rate of LNM was 33.3% in the LVI-free group and 64.3% in the LVI group. Conclusion: Our single-center results suggested that maximum ILN diameter, pathological T stage, pathological differentiation, and LVI were independent risk factors for ILN metastases.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Resumo Objetivo Analisar os significados das masculinidades durante a vivência do câncer peniano e seus tratamentos. Métodos Abordagem qualitativa de pesquisa amparada em referencial teórico da antropologia médica e das masculinidades, com o emprego do método narrativo. Foram entrevistados em profundidade 18 homens com neoplasia peniana em um hospital referência em uro-oncologia do estado de São Paulo. Cada participante foi entrevistado com roteiro de investigação, em média três vezes, sendo as entrevistas audiogravadas, transcritas e analisadas conforme a análise temática indutiva. Resultados Seis participantes realizaram a penectomia parcial e 12 total. Em relação ao estado civil, participaram dois viúvos, dois solteiros, três divorciados e 11 casados, com média de idade de 54 anos. A extirpação do pênis promoveu mudanças significativas na forma como os homens performavam suas masculinidades, sobretudo a hegemônica. Portanto, essa experiência lhes permitiu reinterpretar suas condições de saúde na tentativa de identificar outros elementos hegemônicos que sustentassem suas imagens masculinas. Para alguns foi possível representar um homem inteiro, porém outros se consideram agora meio-homens. Conclusão O adoecimento rompeu com o fluxo biográfico dos participantes, pois antes do câncer peniano a hegemonia os representava como masculinos, entretanto, após a penectomia, eles perdem um órgão que socialmente traz atributos como força, poder, trabalho e virilidade, situação que lhes trouxe a necessidade de reinterpretar o ser masculino em suas culturas. A enfermagem, para promover o cuidado integral ao homem, deve considerar que as masculinidades interferem no processo saúde e doença.

Abstract Objective To analyze masculinity meanings during penile cancer experience and its treatments. Methods Qualitative approach supported in the theoretical framework of medical anthropology and masculinities, with the use of the narrative method. We interviewed in-depth 18 men with penile cancer in a referential Urologic Oncology hospital from the state of São Paulo. Each participant was interviewed on average three times, with a structured script, being the interviews audio-recorded, transcribed, and analyzed according to the inductive thematic analysis. Results Six patients were submitted to the partial penectomy and 12 to the total penectomy. Regarding the marital status, six were widowers, two single, three divorced, and 11 married, with an average age of 54 years old. The penis extirpation fostered significant change in the way men performed their masculinities, even the hegemonic. Thus, this experience allowed them to reinterpret their health conditions to identify other hegemonic elements that sustained their masculine images. For a few, it was possible to represent a full man however, others considered themselves half-men. Conclusion The illness broke the participant's biographic flow because, before penile cancer, the hegemony represented them as masculines, however, after the penectomy, they have lost an organ that is socially related to attributes such as strength, power, work, and virility, situation that brought them the necessity to reinterpret being masculine in their culture. To promote integrality of care to man the nursing must consider that masculinities interfere in the process of health and disease.

ABSTRACT

Introdução: O carcinoma escamoso do pênis é uma neoplasia rara, mas sua incidência e mortalidade específica vêm aumentando. No Brasil, o câncer de pênis constitui 2,1% das neoplasias em homens. O acometimento dos linfonodos inguinais é o fator prognóstico mais importante. Comparados aos pacientes com linfonodos positivos, aqueles com linfonodos histologicamente negativos (pN0) têm o melhor prognóstico; entretanto, a ausência de metástases linfonodais não garante a cura, haja vista que uma proporção destes apresenta recorrência locorregional ou progressão tumoral após o tratamento. Poucos estudos examinaram populações de pacientes com pN0 ou clinicamente negativos (cN0). Objetivos: Avaliar o impacto da expressão imuno-histoquímica da E-caderina e da vimentina como fatores prognósticos para sobrevida global, sobrevida câncer específica e sobrevida livre de doença em pacientes com carcinoma escamoso do pênis clinicamente ou histologicamente negativos para metástase linfonodal. Material e Métodos: Coorte retrospectiva de 116 pacientes cN0 e pN0 com carcinoma escamoso do pênis consecutivamente tratados no A.C.Camargo Cancer Center entre 1953-2017. As variáveis registradas incluíram idade, estadiamento TNM, subtipo histológico, grau de diferenciação tumoral, invasão vascular microscópica, invasão perineural, padrão microscópico da fronte de invasão tumoral (expansivo/infiltrativo) e expressão imuno-histoquímica das proteínas E-caderina e vimentina. As amostras de tumor foram analisadas no centro do tumor e na fronte de invasão tumoral. As análises de sobrevida foram realizadas usando curvas de Kaplan-Meier e testes de log-rank. O modelo de riscos proporcionais de Cox foi usado para determinar quais variáveis influenciaram as taxas de sobrevida global, câncer específica e livre de doença. Resultados: O tempo de seguimento médio foi de 176 meses. A presença de invasão perineural foi associada à alta expressão de vimentina no centro tumoral (p = 0,013), à perda da expressão de Ecaderina no centro do tumor (p = 0,026) e na fronte de invasão tumoral (p = 0,02). A perda da expressão imuno-histoquímica da E-caderina na fronte de invasão e a presença de invasão perineural foram independentemente associadas à sobrevida livre de doença. Conclusões: A perda da expressão imuno-histoquímica da E-caderina na fronte de invasão tumoral e a presença de invasão perineural no tumor primário foram associadas a uma menor sobrevida livre de doença. Alta expressão de vimentina no centro do tumor, perda da expressão da Ecaderina no centro do tumor e na fronte de invasão do tumor foram associadas à presença de invasão perineural no tumor primário.


Introduction: Penile squamous cell carcinoma is a rare neoplasm, but its incidence and specific mortality have been increasing. In Brazil, penile squamous cell carcinoma constitutes 2.1% of neoplasms in men. The involvement of inguinal lymph nodes is the most important prognostic factor. Compared to patients with positive lymph nodes, histologically negative patients (pN0) have the best prognosis; however, the absence of lymph node metastases does not guarantee a cure. Some pN0 patients exhibit locoregional recurrence or tumor progression after treatment. Few studies have examined patient populations with histologically negative (pN0) or clinically negative (cN0) lymph nodes. Objectives: To evaluate the impact of E-cadherin and vimentin expression as prognostic factors for overall survival, cancer-specific survival, and disease-free survival in patients with penile squamous cell carcinoma who were clinically or histologically negative for lymph node metastasis. Material and Methods: Retrospective cohort of 116 patients (cN0 and pN0) treated at A. C. Camargo Cancer Center from 1953 to 2017. Recorded variables included age, TNM staging, histological subtype, degree of tumor differentiation, microscopic vascular invasion, perineural invasion, microscopic pattern of the tumor invasion front (pushing/infiltrating) and vimentin and E-cadherin immunohistochemical expression. Tumor samples were analyzed at the tumor center and at the tumor invasion front. Survival analyses were performed using Kaplan-Meier curves and log-rank testing. Cox's proportional hazards model was used to determine which variables influenced overall survival, disease-free survival, or cancer specific survival. Results: The median follow-up time was 176 months. Perineural invasion was associated with high vimentin expression at tumor center (p = 0.013), loss of E-cadherin expression in the tumor center (p = 0.026) and at the front invasion (p = 0.02). Loss of immunohistochemical E-cadherin expression at the front invasion and the presence of perineural were independently associated with disease-free survival. Conclusions: Lower disease-free survival was associated with loss of immunohistochemical E-cadherin expression at the tumor invasion front, and the presence of perineural invasion. High vimentin expression in the tumor center, loss of E-cadherin expression in the tumor center and in the tumor invasion front were associated with the presence of perineural invasion in the primary tumor.

ABSTRACT

ABSTRACT Purpose: Reviewing surgical procedures using fasciocutaneous and myocutaneous flaps for inguinal reconstruction after lymphadenectomy in metastatic penile cancer. Material and Methods: We reviewed the current literature of the Pubmed database according to PRISMA guidelines. The search terms used were "advanced penile cancer", "groin reconstruction", and "inguinal reconstruction", both alone and in combination. The bibliographic references used in the selected articles were also analyzed to include recent articles into our research. Results: A total of 54 studies were included in this review. About one third of penile cancers are diagnosed with locally advanced disease, often presenting with large lymph node involvement. Defects in the inguinal region resulting from the treatment of metastatic penile cancer are challenging for the surgeon and cause high patient morbidity, rendering primary closure unfeasible. Several fasciocutaneous and myocutaneous flaps of the abdomen and thigh can be used for the reconstruction of the inguinal region, transferring tissue to the affected area, and enabling tensionless closure. Conclusions: The reconstruction of defects in the inguinal region with the aid of flaps allows for faster postoperative recovery and reduces the risk of complications. Thus, the patient will be able to undergo potential necessary adjuvant treatments sooner.

ABSTRACT

ABSTRACT Purpose: To evaluate surgical complications and oncological outcomes of patients submitted to primary radical inguinal surgical debulking (PRISD) and myocutaneous pediculate flap reconstruction (MPFR) for locally advanced penile cancer (PC). Materials and Methods: Forty-two patients with ulcerated and/or fixed bulky inguinal masses underwent unilateral or bilateral PRISD with MPFR. Tensor fascia lata flap (TFL) was the standard of care for all patients. Additional use of the gracilis flap (GF) was carried out when necessary. Contra-lateral radical inguinal lymphadenectomy (RIL) was conduced when PRISD was performed unilaterally. Surgical complications were analyzed and stratified into minor and major according to the Bevan-Thomas classification. Adjunctive treatments were assessed and oncological outcomes analyzed. Results: Of the 42 patients evaluated, 10 (23.8%) underwent bilateral PRISD and 32 (76.2%) unilateral PRISD with contra-lateral RIL, totaling 84 lymphadenectomies. A total of 62 MPFRs were performed, 52 with TFL and 10 with GF. A total of 53 complications were identified, 49 related to PRISD with MPFR and 4 to RIL. Adjuvant chemotherapy was carried out in 16 patients. Median follow-up was 10.8 months with a median overall survival (OS) of 14.0 months against 6.0 months (p=0.006) for patients submitted to PRISD with adjuvant chemotherapy in relation to surgery alone. Conclusions: PRISD alone for advanced loco-regional PC is unlikely to promote long-term survival, although it can lead to temporary local control of the disease. Despite the feasibility of the procedure, it is related to high incidence of complications. Surgical treatment with adjuvant chemotherapy is associated with improved OS.

ABSTRACT

ABSTRACT Purpose: Squamous cell carcinoma (SCC) of the penis is a rare disease in developed countries but is associated with significant morbidity and mortality. A crucial prognostic factor is the presence of inguinal lymph node metastases (ILNM) at the time of diagnosis. At least 25% of cases have micrometastases at the time of diagnosis. Therefore, we performed a literature review of studies evaluating factors, both clinical and pathological, predictive of lymph node metastases in penile SCC. Materials and methods: Studies were identified using PubMed and search terms included the following: penile cancer, penile tumor, penile neoplasm, penile squamous cell carcinoma, inguinal lymph node metastasis, lymph node metastases, nodal metastasis, inguinal node metastasis, inguinal lymph node involvement, predictors, and predictive factor. The number of patients and predictive factors were identified for each study based on OR, HR, or RR in multivariate analyses, as well as their respective significance values. These were compiled to generate a single body of evidence supportive of factors predictive of ILNM in penile SCC. Results: We identified 31 studies, both original articles and meta-analyses, which identified factors predictive of metastases in penile SCC. The following clinical factors were predictive of ILNM in penile SCC: lymphovascular invasion (LVI), increased grade, increased stage (both clinical and pathological), infiltrative and reticular invasion, increased depth of invasion, perineural invasion, and younger patient age at diagnosis. Biochemically, overexpression of p53, SOD2, Ki-67, and ID1 were associated with spread of SCC to inguinal lymph nodes. Diffuse PD-L1 expression, increased SCC-Ag expression, increased NLR, and CRP >20 were also associated with increased ILNM. Conclusions: A multitude of factors are associated with metastasis of SCC of the penis to inguinal lymph nodes, which is associated with poor clinical outcomes. The above factors, most strongly LVI, grade, and node positivity, may be considered when constructing a nomogram to risk-stratify patients and determine eligibility for prophylactic inguinal lymphadenectomy.

ABSTRACT

Abstract Radical penectomy (RP) is infrequently performed as it is reserved for specific cases of penile cancer, hence the paucity of reports regarding surgical and anesthetic considerations. Acute postoperative pain, chronic post-surgical pain, concomitant mood disorders as well as a profound impact on the patient's quality of life have been documented. This case is of a patient with diabetes and coronary heart disease, who presented with advanced, over infected penile cancer, depressive disorder and a history of pain of neuropathic characteristics. The patient underwent radical penectomy using a combined spinal-epidural technique for anesthesia. Preoperatively, the patient was treated with pregabalin and magnesium sulphate, and later received a blood transfusion due to intraoperative blood loss. Adequate intra and postoperative analgesia was achieved with L-bupivacaine given through a peridural catheter during one week. Recovery was good, pain was stabilized to preoperative levels and the patient received pharmacological support and follow-up by psychiatry and the pain team.


Resumen La penectomía radical (PR) es una cirugía infrecuente, reservada para casos específicos de cáncer de pene, por lo que hay escasos informes sobre sus consideraciones quirúrgicas y anestésicas. Se ha documentado dolor agudo postoperatorio, dolor crónico posquirúrgico y alteraciones del estado de ánimo concomitantes, así como un profundo impacto en la calidad de vida posterior del paciente. Se presenta el caso de un paciente diabético y cardiópata coronario con cáncer de pene avanzado y sobreinfectado, trastorno depresivo y dolor previo de características neuropáticas, que recibe técnica combinada espinal-peridural para cirugía de penectomía radical. Se le trata también con pregabalina preoperatoria, sulfato de magnesio y transfusión por sangrado quirúrgico. Se otorgó una adecuada analgesia intra y postoperatoria, mediante catéter peridural con L-bupivacaína hasta por una semana. El paciente tuvo una buena recuperación, estabilización del dolor a niveles preoperatorios, controles y apoyo farmacológico por psiquiatría de enlace y equipo del dolor.

ABSTRACT

Introducción: Entre las lesiones malignas que se describen, se encuentra el cáncer de pene. Esta entidad constituye del 2 al 5 por ciento de los tumores urogenitales masculinos; la lesión metastásica es muy poco frecuente. Objetivos: Describir las características clínicas y evolución tórpida de un paciente con metástasis en el pene, de una neoplasia del colon. Caso clínico: Paciente de 54 años, antecedentes personales de salud, fumador, historia de hiperplasia prostática benigna y prostatitis crónica. Ingresa con dolor en hemiabdomen inferior y tumoración abdominal. Se diagnostica plastrón intraabdominal. Es intervenido quirúrgicamente; la biopsia de la lesión informa adenocarcinoma de colon. A los 7 días de evolución aparecen lesiones en el glande, que resultaron metástasis del adenocarcinoma de colon. Fallece por complicaciones de la enfermedad. Conclusiones: Las metástasis de las neoplasias del colon, en el pene, son infrecuentes; indican un estadio avanzado de la enfermedad, con un pronóstico desfavorable(AU)

ABSTRACT

ABSTRACT Purpose: To evaluate the erectile function in patients who underwent partial penectomy and identify factors associated with penile functional status. Materials and Methods: We identified patients who underwent partial penectomy due to penile cancer between 2009 and 2014. Clinical and pathological characteristics included patient age at the time of diagnosis, obesity, hypertension, dyslipidemia, diabetes, smoking, metabolic syndrome, Eastern Cooperative Oncology Group (ECOG) status, penile shaft length, tumor size, primary tumor stage (pT), clinical nodal status, and local recurrence. Erectile function was assessed prospectively with the International Index of Erectile Function (IIEF-5) at least 3 months after partial penectomy. Results: A total of 81 patients met analysis criteria. At the diagnosis, the median age was 62 years (range from 30 to 88). Median follow-up was 17 months (IQR 7-36). Of total patients, 37 (45%) had T2 or higher disease. Clinically positive nodes were present in 16 (20%) patients and seven (8.6%) developed local recurrence. Fifty patients (62%) had erectile dysfunction (ED) after partial penectomy, 30% had moderate or severe erectile dysfunction scores. Patients with ED versus without ED were similar in baseline characteristics except for age, penile shaft length, and presence of inguinal adenopathy (p <0.05). Multivariate analysis using logistic regression confirmed that older patients, shorter penile shaft length, and clinically positive lymph node were significantly associated with ED. Conclusion: Partial penectomy due to penile cancer provides adequate local control of the disease, however, proper counselling is important especially in relation to ED consequences. Preservation of penile length yields to more optimal erectile recovery.

ABSTRACT

Objetivo: Relatar o caso de um paciente diagnosticado com linfoma peniano primário, um dos subtipos menos comuns de câncer de pênis. Caso clínico: Paciente masculino, 63 anos, hígido, com queixa de ulcerações dolorosas em região balano-prepucial. Sem queixas urinárias, traumatismo peniano ou relação sexual desprotegida. Ao exame inicial, pênis com prepúcio exuberante, sinais de má higiene, tecido necrótico em glande e parafimose. Optou-se por postectomia, desbridamento de glande e cistostomia de proteção, com anatomopatológico demonstrando neoplasia maligna pouco diferenciada e análise imuno-histoquímica sugerindo linfoma de células B. O paciente realizou seis ciclos de quimioterapia, com remissão completa dos sintomas no quarto ciclo. Foi submetido à reconstrução de uretra e glande posteriormente, pela técnica de Mathieu (retalho cutâneo). Comentários: O linfoma peniano primário é ainda pouco relatado e conhecido. Ainda que seu manejo seja controverso, a quimioterapia adjuvante com terapia cirúrgica reconstrutiva se demonstrou uma opção eficiente de tratamento


Objective: To report the case of a patient diagnosed with primary penile lymphoma. Clinical case: A 63-years-old male patient presented with ulcerated lesions on the penis with a 2-week evolution. The patient denied urinary symptoms, penile trauma, or unprotected sex. The initial examination showed a penis with an exuberant foreskin and signs of poor local hygiene, with paraphimosis and necrotic tissue on the gland. A postectomy and debridement of the gland was performed, and the anatomopathological exam showed poorly differentiated malignancy, while the immunohistochemical analysis suggested B-cell lymphoma. The patient was submitted to six cycles of chemotherapy, with complete remission of the symptoms after the fourth cycle. In sequence, a reconstruction of the urethra and glans was performed using the Mathieu's technique. Comments: Primary penile lymphoma is still a poorly reported disease. Although its management remains controversial, adjuvant chemotherapy with reconstructive surgical therapy showed to be an efficient approach

ABSTRACT

Malignant tumors of the penis are rare, most of them being squamous cell carcinomas (SCCs). We report the case of a 75-year-old man with a large penile mass submitted to partial penectomy. The specimen showed an exophytic mass involving the glans, coronal sulcus, and prepuce. Microscopic examination showed a carcinoma with two distinct areas: a mixed SCC and a sarcomatoid carcinoma. The SCC component had areas of verrucous carcinoma and areas of classical invasive SCC. The tumor cells expressed p63 with the absence of p16 expression. Vimentin and p53 were positive in the sarcomatous component. The morphology and immunohistochemistry were compatible with mixed SCC (verrucous hybrid-sarcomatoid carcinoma). Additionally, the tumor cells also expressed 3 different clones of PDL1 (22C3, SP263, and SP142). Two months later, the patient presented local recurrence with multiple lymph nodes and lung metastases, dying 7 weeks later. Mixed tumors represent diagnostic challenges. The correct identification of adverse prognostic factors can be the first step to implement the treatment with a higher probability of success.
