Treatment of advanced penile cancer

Treatment of advanced penile cancer

Urologe A 42(11): 1466-1469, November

Skin infiltration and locoregional lymph node extension in metastatic penile cancer leads to destruction in the inguinal and perineal region. Efficacy of systemic polychemotherapy based on cisplatin, methotrexate, and bleomycin (CMB scheme) is limited with an objective remission rate up to 30% only. The obligatorily superinfected defects require tension-free and extended coverage with immediate myocutaneous flaps after surgical resection. Pedicle flaps, consisting of skin, fascia, muscle, and the supplying vessels, are used to cover the post-resection defects. In the field of surgical urooncology the following myocutaneous flaps listed with the supplying vessels have proved themselves: M. tensor fasciae latae flap (A. circumflexa femoris lateralis), M. rectus abdominis flap (A. epigastrica inferior), M. gluteus maximus flap (A. glutea inferior). Data concerning a prospective study for neoadjuvant chemotherapy with CMB followed by surgical tumor resection with immediate myocutaneous flap reconstruction are presented. In 15 patients (median age: 69.7 years) suffering from squamous cell carcinoma of the penis (Tx, N3, M1 cutis), a surgical excision of the tumor was performed after neoadjuvant chemotherapy (median: 2.4 cycles) and antibiotic pretreatment. All patients received coverage of the femoral vessels with a musculus sartorius transfer on both sides. An extended (up to 45X30 cm) tension-free coverage of groin defects was performed in two patients with a unilateral M. tensor fasciae latae flap (TFL) and in eight patients with a bilateral TFL. One patient received a M. gluteus maximus flap (GMFL) on both sides, three patients were treated with a combination of M. rectus abdominis flap (RFL) and TFL, and one patient received a combination of two TFL, one GMFL as well as one RFL. Of 31 myocutaneous pedicle flaps, 2 developed distant necrosis of the flap, in which one GMFL and one TFL were affected. No complete necrosis of the pedicle flap occurred. Primary wound healing was found in 29 of 31 myocutaneous flaps. The covering of groin defects by the use of myocutaneous flaps, such as the M. tensor fasciae latae, M. rectus abdominis, and M. gluteus maximus flap, is a method of first choice in the primary treatment of even bacterially contaminated wounds or after radiation therapy. The techniques of pedicle flaps are comparably applied in oncology and traumatology.
