Of 322 patients with squamous cell carcinoma of the penis, conservative therapy was conducted in 162 (50.3%) untreated patients free of metastases to regional lymph nodes. 125, 14 and 23 patients received radiation, drug and drug+radiation treatment, respectively. The efficacy of conservative treatment reached 74.6%, complete regression of the tumor was achieved in 61.1% of the cases. 8 patients with partial response (reduction of the tumor to 1 cm in size) were exposed to cryodestruction of the residual tumor. Thus, in 111 of 162 patients the penis was not amputated. Follow-up results show that within the period 4.5-14 years the disease relapsed in 20 of 111 patients, 4 patients throughout follow-up month 3-6 developed metastases to regional lymph nodes in the absence of recurrent tumor. It is concluded that amputation of the penis in early cancer should be made only in uneffective sparing therapy.

Squamous cell carcinoma of the penis is an uncommon but potentially fatal malignancy, especially in the presence of inguinal lymph node metastases. The morbidity of inguinal lymphadenectomy precludes its use as a staging procedure on all patients, and the inability to predict which patients will progress to nodal disease remains a difficult problem. This article describes our use of deoxyribonucleic acid flow cytometry on paraffin-embedded specimens of 17 consecutive patients with histologically-diagnosed squamous cell carcinoma of the penis. Our results suggest that patients with squamous cell carcinoma of the penis and a high DNA index may be at an increased risk of disease progression and therefore may be candidates for aggressive surgical management, and also suggest that DNA flow cytometry may be a reliable prognostic indicator for selecting which patients would benefit most from inguinal lymphadenectomy.

Since squamous cell carcinoma of the penis is rare, prospective trials do not exist. Therefore, new treatment strategies have to be developed. Based on our experience with the treatment of 22 patients with penile squamous cell carcinoma, we describe our therapeutic approaches. Ten patients with superficial disease (T1-2N0M0) were treated with partial penectomy. The 3-year survival rate amounted to 90%. In patients with extensive disease (T3-4 or N1-3) a partial or total penectomy was performed. After initial antibiotic therapy for 4 weeks, patients underwent inguinal lymph-node dissection and if the nodes were positive, additional pelvic lymph-node dissection. In patients with ulcerous inguinal lymph-node metastases surgical resection was performed, covering the wound with a musculocutaneous flap (tensor fascia lata flap n = 2; rectus abdominis flap n = 1). The 3-year survival rate of patients with T1-2N1 tumours (n = 4) was 67% and with T3-4N1-3 (n = 8) 25%. Patients with distant metastases received inductive systemic chemotherapy with cisplatin, methotrexate and bleomycin. Objective responses occurred in 22% (1 CR, 1 PR) of 9 patients. These results suggest that immediate radical surgery with lymph-node dissection is the best treatment for squamous cell carcinoma of the penis.

From July 1994 to January 1999, three patients with penile squamous cell carcinoma with deep inguinal lymph node metastases without distant metastases were treated with multimodality treatment including intra-arterial infusion chemotherapy mainly with monthly courses of cisplatin, methotrexate and bleomycin. One patient achieved a complete response and 2 achieved a partial response. It appears to be reasonable to presume that intra-arterial chemotherapy has a beneficial effect in the management of penile cancer with fixed metastatic inguinal lymph nodes, but a larger number of patients and longer follow-up are required to confirm these results.

Lymphoscintigraphy for sentinel node (SN) identification has been extensively validated in breast cancer and melanoma. The aim of this study was to evaluate the findings of lymphoscintigraphy for SN identification in carcinoma of the penis. Lymphoscintigraphy was performed in 74 consecutive patients (mean age 62.2 years, range 28-87 years) with clinically lymph node-negative squamous cell carcinoma of the penis (stage T2 or greater). Following local anaesthesia by xylocaine 10% spray, technetium-99m nanocolloid (mean dose 64.8 MBq, range 40-131 MBq) in a volume of 0.3-0.4 ml was injected intradermally around the tumour. Shortly after injection, a 20-min dynamic study was performed with a dual-head gamma camera; subsequently, static anterior and lateral images were obtained at 30 min and 2 h using simultaneous cobalt-57 flood source transmission scanning. 57Co-assisted skin marking defined SN location for gamma probe/blue dye-guided biopsy, which was performed the next day. The SN visualization rate was 97% (72/74). Lymphatic drainage was bilateral in 81% of the cases (58/72), exclusively to the left groin in 13% (9/72) and only to the right groin in 6%. Bilateral lymph node drainage was synchronous in 38% (22/58) and asynchronous in 62% (in 18 patients the initial route was the left groin, and in the other 18, the right groin). Visualization before 30 min occurred in 66 patients (93%), in 64 of them (88%) already during the dynamic study. A total of 173 SNs were visualized (85 in the right groin, 88 in the left groin). Pitfalls were caused by inguinal skin contamination during injection (four patients) and intracavernous administration (one patient). At surgery, a total of 161 SNs were identified and removed. Sixteen patients (22%) had a tumour-positive SN and underwent standard regional lymph node dissection subsequently. During follow-up (median 28 months, range 3-74 months), two patients with a negative SN developed lymph node metastases in the mapped basin. It is concluded that penile lymphoscintigraphy is a valid and well-tolerated method for lymphatic mapping and SN identification. Although bilateral early inguinal drainage is the most frequent pattern, late imaging is recommended principally in patients with initial unilateral drainage in order to exclude delayed lymph node filling in the contralateral groin. SN identification may lead to a more accurate staging and avoid extensive lymph node dissection in the majority of patients with penile carcinoma.

The ability to predict cancer progression may help the clinical management of patients with penile squamous cell carcinoma. We studied 22 cases of squamous cell carcinoma of the penis diagnosed between 1989 and 1998. The depth of invasion was measured from the basement membrane of the squamous epithelium to the deepest invasive cancer cells. Cancer progression was defined as the development of lymph node metastasis or distant metastasis. The mean patient age was 63 years and the mean follow-up was 28 months. Ten patients developed cancer progression. The mean depth of invasion among patients with cancer progression was 9.8 mM, as compared to the mean depth of invasion of 4.0 mM among those patients without cancer progression (P =.02). Vascular invasion was also predictive of cancer progression (P =.02). Metastases developed in the majority (6 out of 7) of cases invading more than 6 mM, but developed only in a minority (4 out of 15) of cases invading 6 mM or less. We conclude that depth of invasion and vascular invasion are significant predictors of cancer progression for penile squamous cell carcinoma.

We present a series of 5 penile clear cell carcinomas, which arose in middle-aged men at the inner side of the foreskin. They were large, exophytic, partly ulcerated, and widely invasive tumors with sharp demarcation to the surrounding normal skin/mucosa. Histologically, they were composed of large clear cells with intracytoplasmic PAS/d-PAS-positive material and showed extensive lymphatic and blood vessel invasion. Strong staining with antibodies to Muc-1, EMA, and CEA was typical. All carcinomas harbored HPV16 DNA, although only one carcinoma revealed HPV-related cytologic cell changes. All 5 patients had extensive, partly cystic inguinal lymph node metastases with a striking clear cell differentiation and focal dense sclerotic basement membrane material, either at or within several months after initial diagnosis. Two patients are alive without disease after 7 and 10 years. One patient died after 9 months of widespread disease and 2 patients are presently alive at 7 and 17 months follow-up with widespread lymphatic and hematogenous metastases despite adjuvant chemo- and radiation therapy. In contrast to squamous cell carcinoma, penile clear cell carcinomas show extensive blood and lymph vessel invasion and early metastases to regional lymph nodes. Clear cell carcinomas represent a distinct group of penile cancers that may have a different clinical behavior than usual penile squamous cell carcinomas.

Sarcomatoid carcinomas are uncommon, high-grade tumors, predominantly composed of spindle cells. Only a few cases arising in the penis have been reported. The aim of this study is to better define the clinicopathologic features of this neoplasm. A total of 400 cases of squamous cell carcinoma of the penis were reviewed from which 15 sarcomatoid carcinomas (4%) were identified. Clinical and pathologic features were evaluated in all cases. Immunohistochemical studies for expression of AE1/AE3, Cam 5.2, 34betaE12, EMA, vimentin, muscle specific actin, smooth muscle actin, desmin, S-100, p63, and p53 and in situ hybridization studies for HPV were performed in 5 cases. Information about lymph node status was available in 9 cases, and follow-up in 5 cases. The mean age was 59 years, and mean tumor size was 5 cm. Grossly, most tumors were large, polypoid, and ulcerated masses frequently affecting the glans (93%) and deeply invading corpora cavernosa (80%) and skin. Microscopically, the lesions were predominantly composed of atypical spindle cells disposed in interlacing fascicles, resembling fibrosarcoma or leiomyosarcoma, sometimes admixed with pleomorphic giant cells mimicking malignant fibrous histiocytoma. One case was predominantly composed of myxoid areas. Less frequent and focal patterns were pseudoangiomatous and epithelioid. Mitotic figures were numerous, and necrosis was prominent. Foci of heterologous differentiation toward bone (osteosarcomatous component) were present in 1 case. Four cases showed a minor mixed component of usual, papillary, verrucous, and basaloid carcinoma. Intrapenile metastasis ("satellitosis") was present in 4 tumors. One of the cases was multicentric with a separate independent focus of well-differentiated carcinoma with pseudohyperplastic features. Associated low- and high-grade squamous intraepithelial lesions were noted in 73% of the cases. Immunohistochemical studies and HPV in situ hybridization were done in 5 cases. The spindle cells were diffusely positive for vimentin and p53 and showed at least intermediate expression of 34betaE12 and p63 in all cases. EMA and AE1/AE3 were focally positive in 60% of the cases, and Cam 5.2 was focally positive in 1 case. Tumor cells failed to express muscle specific actin, smooth muscle actin, desmin, and S-100. HPV in situ hybridization was negative in all cases. Inguinal metastases were present in 89% of the cases. Two of five patients with adequate follow-up died of disease within 8 months of the diagnoses. In conclusion, penile sarcomatoid carcinomas are unusual, large, and aggressive tumors usually associated with lymph node metastasis and poor outcome. Differential diagnoses include sarcoma and melanoma. Cytokeratin 34betaE12 and p63 appear to be the more specific and sensitive markers to categorize these tumors as epithelial. Diffuse immunoreactivity for p53, compared with a more basal and focal reactivity in differentiated squamous cell carcinoma, may be indicative of a late mutation in the natural progression of the disease.

Early-stage penile squamous cell carcinoma with subsequent distant metastases is rare. We report a case of a 35-year-old man with Stage pT1pN0 penile squamous cell carcinoma who underwent circumcision and bilateral inguinal lymphadenectomy. Further in the disease course, the patient developed metastases in the kidney, adrenal gland, retroperitoneal lymph nodes, lung, and brain. He underwent multiple resections, whole brain radiotherapy, and several chemotherapy regimens. All these metastases were histologically confirmed. Forty months after the first diagnosis, the patient died of thromboembolic complications. This case was unique because of the unusual pattern of dissemination, especially the spread to the brain.

We report a case of rapid progression of carcinoma of the penis, in a 90-year-old man, one year after yttrium-aluminum-garnet (YAG) laser therapy. This patient had received YAG laser ablation for well-differentiated, verrucous, squamous cell carcinoma of the penis at the age of 89, and was found on physical examination to have local recurrence. The recurrent tumors were surgically resected, and the histological examination revealed infiltrating, poorly-differentiated squamous cell carcinoma. The patient developed metastases of bilateral inguinal lymph nodes and liver and died of penile carcinoma. We should be aware of the possibility of an unfavorable outcome following the use of laser therapy against carcinoma of the penis.
