[Organ-preserving treatment in cancer of the penis]
Abstract:
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.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
