Clinical Outcomes of Perioperative Chemotherapy in Patients With Locally Advanced Penile Squamous-Cell Carcinoma: Results of a Multicenter Analysis
Clin Genitourin Cancer (2017) 15:548-555 e3.
BACKGROUND: The prognosis of patients with locally advanced penile squamous-cell carcinoma is primarily related to the extent of lymph node metastases. Surgery alone yields suboptimal results, and there is a paucity of data on these patients' outcomes. PATIENTS AND METHODS: This retrospective study evaluated patients who received neoadjuvant or adjuvant chemotherapy from 1990 onward at 12 centers. Cox models were used to investigate prognostic factors for relapse-free survival and overall survival (OS). RESULTS: Among the 201 included patients, 39 (19.4%) had disease of T3-4 and N0 clinical stage; the remaining patients had clinical lymph node involvement (cN+). Ninety-four patients received neoadjuvant chemotherapy (group 1), 78 received adjuvant chemotherapy (group 2), and 21 received both (group 3). Eight patients for whom the timing of perioperative chemotherapy administration was unavailable were included in the Cox analyses. Forty-three patients (21.4%) received chemoradiation. Multivariate analysis for OS (n = 172) revealed bilateral disease (P = .035) as a negative prognostic factor, while pelvic cN+ tended to be nonsignificantly associated with decreased OS (P = .076). One-year relapse-free survival was 35.6%, 60.6%, and 45.1% in the 3 groups, respectively. One-year OS was 61.3%, 82.2%, and 75%, respectively. No significant differences were seen on univariable analyses for OS between the groups (P = .45). Platinum type of chemotherapy and chemoradiation were not significantly associated with any outcome analyzed. CONCLUSION: Benchmark survival estimates for patients receiving perioperative chemotherapy for locally advanced penile squamous-cell carcinoma have been provided, with no substantial differences observed between neoadjuvant and adjuvant administration. This analysis may result in improved patient information, although prospective studies are warranted.
