Cancer of the penis is an important health problem in India, causing significant morbidity. Involvement of locoregional lymph nodes is the most significant prognostic factor for patients with penile cancer. In this study, we reviewed clinical data of all patients who underwent modified inguinal lymph node dissection as a means to diagnose micro-metastasis in inguinal lymph nodes, and analysed the outcomes. We retrospectively reviewed the hospital clinical charts of patients treated for carcinoma of the penis. Inguinal and distant metastases were assessed by physical examination, ultrasound imaging of the inguinal region, computed tomography of the abdomen and pelvis and a chest radiograph. Patients with clinically negative inguinal lymph nodes underwent modified lymph node dissection (mILND) both to diagnose and stage the disease. Complications occurring during a 30-day period after surgery were defined as early and thereafter as late complications. A total of 40 patients with a mean age of 52.27±13.10 (range 25-73) years underwent mILND. Wedge biopsy from the primary lesion had revealed intermediate-risk disease in 22 (55%) patients and high-risk disease in 18 (45%) patients. Histopathological examination of the primary penile lesion revealed a pT1 lesion in 32 patients and a pT2 lesion in the remaining 8 patients. Fourteen (35%) of the 40 patients showed micro-metastases in the inguinal lymph nodes on frozen sections. The mean follow-up in these patients was 56.6±18.09 months. There were no instances of local or systemic recurrences seen in 38 (95%) patients within 5 years. Superficial lymph node dissection and where facilities are available DSLNB remain the standard of care in the management of patients with clinically groin-negative (cN0) intermediate- and high-risk groups. Modified inguinal lymph node dissection would be a safe and appropriate alternative to this in all centres that do not have access to newer modalities like DSLNB, video-endoscopic (VEIL) or robotic-assisted techniques.
