Neoadjuvant and adjuvant chemotherapy with methotrexate, cisplatin and bleomycin for advanced penile cancer: a case report

A 58-year-old male consulted our hospital because of penile swelling and pain with bilateral inguinal lymphadenopathy. Pathological examination of the penile tumor and right superficial inguinal lymph node biopsy demonstrated moderately differentiated squamous cell carcinoma with lymph node metastasis. We diagnosed the tumor inoperable radically and adjuvant chemotherapy with methotrexate, cisplatin and bleomycin was administered, followed by partial penectomy and left superficial lymphadenectomy. The surgical specimens showed few viable tumor cells. This combination chemotherapy is suggested to be effective for the treatment of advanced penile cancer.     

Successful penile preservation surgery for large proximal penile carcinoma: 7-year follow-up

We report the case of a 49-year-old man who presented with a 2-month history of a progressively enlarging squamous cell carcinoma on the skin of the proximal penile shaft. The patient refused penectomy and requested penile preservation. He was treated with wide surgical excision of the tumor, followed by a full-thickness vascularized scrotal skin flap. The treatment proved curative, with excellent cosmetic and functional results. The patient is without evidence of disease recurrence 7 years after therapy.     

Successful penile reconstruction after multimodal therapy in patients with primitive neuroectodermal tumor originating from the penis

We herein present an extremely rare case of primitive neuroectodermal tumor originating in the penis. A 16‐year‐old male adolescent presented with painful penile swelling. Pathological, immunohistochemical and cytogenetical examinations of the specimens obtained from total penectomy confirmed the diagnosis of primitive neuroectodermal tumor. After total penectomy, the patient received adjuvant chemotherapy with ifosfamide‐based regimen for 48 weeks. As a series of therapies, the patient underwent penile reconstruction surgery after completing adjuvant chemotherapy. The patient has not shown any evidence of recurrence for the 7 years after penile reconstruction surgery, and voiding function is completely normal. A favorable outcome was observed by multimodal therapy including aggressive resection for local control, intensive adjuvant chemotherapy, and penile reconstruction with cosmetic and functional success. Similar therapeutic approaches might be selected for children with primary malignant tumors of the penis.     

Re: Prognosis of untreated stage A1 prostatic carcinoma: a study of 94 cases with extended followup

A surgical technique is described for the treatment of carcinoma and injury involving the distal penile shaft in which a standard partial penectomy would leave inadequate penile length for satisfactory voiding. As an alternative to standard total penectomy with perineal urethrostomy that is used in this situation, partial penectomy is performed and a flap of suprapubic and scrotal skin is rolled into a new proximal penile shaft covering. This technique offers the patient the advantage of voiding in the standing position with a penile stump, and the possibility for sexual satisfaction and less physical disfigurement.     

Laser surgery for the treatment of squamous cell carcinoma of the penis

We describe our experience with six cases of squamous cell carcinoma of the penis treated with the carbon dioxide and neodymium yttrium aluminum garnet (Nd:YAG) lasers. One patient had carcinoma in situ. One patient had a T1 tumor. Two patients had T2 disease and two patients had T3 carcinoma of the penis when seen. The patients were followed up from 13 to 64 months. The patients with carcinoma in situ and T1 carcinoma of the penis were tumor-free at a mean follow-up of 45 months. One patient with T2 carcinoma apparently had a complete response to surgery; however, he was seen 56 months after the initial laser treatment with a new invasive penile tumor located at a different site that failed to respond to laser treatment and required a penectomy. Another man with T2 carcinoma as well as the two men with T3 carcinoma failed to respond to laser treatment and required a penectomy. It appears that laser surgery offers the potential for cure in patients with carcinoma of the penis with superficial involvement.     

Surgical treatment of a rare case of penile squamous cell carcinoma in a 65-year-old man

Penile squamous cell carcinoma has been commonly reported in the past decades. We describe a rare case of a huge squamous cell Carcinoma of the penis in a 65-year-old patient with a 4-year history of tumor growth, for which total penectomy, perineal urethrostomy and bilateral inguinal lymphadenectomy were carried out. We suggest that aggressive surgical intervention should be recommended for those with well-differentiated penile carcinoma regardless of the size of the tumor.     

Trends in treatment of cT1 penile cancer: Analysis of the National Cancer Database

ObjectiveTo characterize the treatment trends and outcomes in clinical stage T1 penile cancer using the National Cancer Database (NCDB).MethodsThe National Cancer Database was queried for all men with cT1 penile cancer from 2004 to 2015. Patients were categorized as cT1a or cT1b. Treatment was categorized as no treatment, local therapy (including penile sparing therapies), partial penectomy, or radical penectomy. Trends in treatment were analyzed over time and in correlation with stage and demographic variables. Stage and treatment type were evaluated in respect to pathological outcomes and survival.ResultsA total of 2,484 men were identified with cT1 penile cancer, 90.1% of which had cT1a disease. The most common treatments were local therapy for cT1a and partial penectomy for cT1b. Over the time period studied, use of local therapy decreased while use of partial or radical penectomy increased. Patients treated at low volume facilities were more likely to undergo no treatment (8.0% vs. 6.5% in high volume) or local therapy (49.9% vs. 41.5% in high volume, P < 0.001). Local therapy was associated with increased risk of positive margin (odds ratio 4.7, P < 0.001) and positive margin was associated with a trend toward decreased overall survival (P = 0.07).ConclusionsIn the past decade, there has been decreased use of local therapy and increased use of partial or radical penectomy in cT1 penile cancer. Men treated at low volume facilities are more likely to be treated with local therapy which is associated with increased rates of positive margins and may also be associated with a trend toward decreased overall survival. Centralization of care in T1 penile cancer may lead to improved outcomes.     

Spindle cell sarcoma of the penis: a case report

A 75-year-old man, with a past history of radiation therapy for prostatic carcinoma ten years ago, was referred to our hospital with complaints of penile tumor. After pathological examination by core biopsy, the patient was treated by radical penectomy for a penile tumor. Pathological examinations demonstrated that the tumor was composed of pleomorphic spindle cells without any differentiation tendency and diagnosed as spindle cell sarcoma. Although the patient had a past history of radiation therapy for the prostate, the causal relation of development of penile sarcoma with the radiation therapy was uncertain because the main tumor was very near but outside of the irradiation field. The sarcoma rarely occurs in the penis, and this is the first report of penile spindle cell sarcoma, to our knowledge.

Primary neuroectodermal tumor of penis (PNET)--a case report

Primary neuroectodermal tumor (PNET) is a rare entity with high malignant potential. It usually affects the skeletal system and primary extraskeletal involvement is uncommon. Because of rarity of tumor in the penis, only a few cases have been reported. A 17-year-old male adolescent presented with painless penile swelling of 4 weeks' duration. Clinical examination revealed multiple, 1 cm hard nodules palpable on penile shaft. Open incisional biopsy of the penile nodule revealed an undifferentiated malignant round cell tumor and on immunohistochemistry a diagnosis of PNET was made. Metastatic workup was negative. Total penectomy and perineal urethrostomy was performed, and subsequently adjuvant chemotherapy was given.

Positive resection margins in partial penectomies: sites of involvement and proposal of local routes of spread of penile squamous cell carcinoma

Recurrence in patients with penile carcinoma occurs in about one third of cases, usually due to insufficient surgery or positive resection margins. An evaluation of surgical resection margins in penectomy specimens was performed to determine precise anatomic sites of tumor involvement, hoping to advance knowledge concerning the local routes of spread of penile carcinomas. A pathologic study of 80 partial penectomies revealed 14 positive margins. Margins were examined after their separation from the main specimen as follows: 1) proximal urethra and surrounding tissues consisting of urethral epithelium with Litree glands, lamina propria, corpus spongiosum, and penile fascia (periurethral cylinder); 2) proximal shaft with corresponding corpora cavernosa separated and surrounded by the tunica albuginea and penile fascia; and 3) skin of shaft with underlying corporal dartos. In 9 patients, only one site was involved by carcinoma, and in 5 there were multiple contiguous sites (for a total of 20 anatomic sites). The distribution of the various sites involved by carcinoma was as follows: urethral epithelium, 4 cases (2 in situ and 2 invasive carcinomas including intraluminal spread); lamina propria, 5 cases; corpus spongiosum, 3 cases; penile fascia, 6 cases; and corpora cavernosa and skin, 1 case each. One of the in situ lesions was discontinuous with the main glans tumor, and the other one was continuous with it. The penile fascia was the most commonly involved site followed by the urethral lamina propria and epithelium. Dissemination to outer skin, corpora cavernosa, and corpus spongiosum was less frequent. The highly vascularized and innervated loose connective tissue of the penile fascia appears to facilitate tumor spread. The urethra is either a pathway for in situ tumor progression from glans to urethra or part of a field prone to malignant transformation. The infrequent involvement of corpora cavernosa is probably due to the tunica albuginea acting as a barrier preventing tumor spread. Based on these observations and the examination of hundreds of penectomy specimens, we are proposing five probable routes of local spread for penile cancer: 1) horizontal and superficially spreading from one epithelial mucosal compartment (glans, coronal sulcus, and foreskin) to the other; 2) following the penile fascia; 3) through spaces created by feeding vessels in the tunica albuginea; 4) vertical spreading involving step-by-step different penile anatomic compartments; and 5) along the urethral epithelium.     

Multi-institutional long-term experience with conservative surgery for invasive penile carcinoma

PURPOSE: Invasive squamous cell carcinoma of the penis occurs on the glans, prepuce, glans and prepuce, coronal sulcus and shaft. Penile squamous cell carcinoma subsequently invades local structures, corpora cavernosa and the urethra, and metastasizes to the inguinal lymph nodes. Invasive squamous cell carcinoma of the penis usually requires total or partial penectomy. We studied the effect of primary tumor resections tailored to the anatomical extent of the cancer with preservation of uninvolved structures in select patients with invasive penile squamous cell carcinoma. MATERIALS AND METHODS: A total of 30 patients between 39 and 82 years old were treated with unconventional conservative surgical excision of the primary penile lesion. More than 130 patients were excluded from the study because they were treated with partial or total penectomy, Mohs' surgery or more extensive surgery. The 30 patients underwent preoperative biopsy with careful mapping of the extent of the disease. Patient age, tumor extent and grade, operative details, outcome and length of followup were analyzed. RESULTS: Tumor size ranged from 1.5 to 8 cm. in diameter. Tumors were well differentiated in 19 patients, moderately differentiated in 5 and poorly differentiated in 6. A total of 17 patients underwent ilioinguinal lymphadenectomy, 12 of whom had pathologically positive lymph nodes. Inguinal radiation was used in 2 patients. Chemotherapy was given to 7 patients with extensive inguinal lymphadenopathy and to 2 of 5 with pathologically positive lymph nodes. Followup ranged from 12 to 360 months. A total of 21 patients had no evidence of disease at last followup. Tumor resection with no sacrifice of function was performed in 2 patients in whom 3 small recurrences developed. One patient with numerous tumors had 2 small recurrences, which were completely excised with no further recurrence. Of the 7 patients with advanced lymphadenopathy 5 and of 5 patients with pathologically positive lymph nodes at presentation 1 died of the cancer but had no local recurrence in the penis. CONCLUSIONS: In a minority of patients with anatomically suitable penile cancer conservative surgical techniques are safe and provide equal tumor control compared to conventional resections. The anatomical situation and tumor characteristics should dictate the choice of treatment for the primary penile lesion. Inguinal lymph nodes should be managed by appropriately established guidelines but should not influence the extent of primary penile lesion resection.     

Reconstructive surgery in penile trauma and cancer

This article provides an overview of the current concepts in reconstructive surgery following penile trauma, penile fracture and penile cancer. It covers the initial management of penile trauma, with the aim of preservation of as much viable tissue as is practical, and also provides advice on dealing with penile avulsion and amputation injuries. The best treatment for penile fracture-immediate surgical exploration and repair-is outlined and discussed. Finally, penile cancer management is reviewed, from initial biopsy to definitive treatment of the penile lesion-including wide excision, partial glansectomy, total glansectomy, and partial and total penectomy. It is concluded that appropriate surgery in all these conditions reduces subsequent long-term problems in sexual function, cosmesis, psychology, and (in cancer cases) longevity. The same reconstructive techniques can be applied for different penile conditions, and it is suggested that surgeons become experienced in genital surgery as a whole, rather than in oncology or trauma alone.

Priapismo secundario a infiltración peneana por contigüidad de carcinoma vesical infiltrante

Metastasic priapism is a rare entity produced by tumor cell implantation or direct infiltration of corpora cavernousum of the penis. In up to 80% of cases the primary tumor has an urological origen like prostate or bladder cancers. Treatment depends on syntomatology and patient’s prognosis. Generally, average survival in these patients is poor due to metastasic progression, among 1 to 1 and a half years.We present a case report of secondary priapism for direct bladder carcinoma’s invasion of the corpora cavernousum. A total penectomy due to a penile infected necrosis was required.     

A case of leiomyosarcoma of the penis

A case of leiomyosarcoma of the penis is reported. A 27-year-old-man presented to our department with a mass at the root of the penis. Biopsy of the tumor showed that the tumor was leiomyosarcoma. The tumor was clinically and pathologically categorized into the deep type. Despite total penectomy and adjuvant chemotherapy, the patient died from disseminated disease 14 months after surgery. This is the 45th case of penile leiomyosarcoma.     

Metastases to the penis from carcinoma of the prostate

A 58-year-old man presented with dysuria at the Osaka Medical College Hospital in November 1996. Laboratory examination revealed elevated serum prostate-specific antigen (PSA) to > 100 ng/mL. Adenocarcinoma of the prostate with metastasis to the bone was diagnosed after a biopsy of the prostate and bone scintigraphy; hormonal therapy was administered. Although bone metastasis was well controlled and the serum PSA level declined to within normal levels (2.0 ng/mL), several painless nodules were found on the penile glans. Biopsy of the nodules showed that the penile tumor was a metastasis from the prostate cancer. The patient underwent partial penectomy for relief from penile pain. The serum PSA level showed no elevation 3 months after the partial penectomy, suggesting that careful observation of prostate cancer patients is necessary, even when oseous metastasis is well controlled and serum PSA levels are kept within normal ranges by hormonal therapy. The case also indicates that urologists should consider the possibility of metastasis to the penis from prostate cancer.
