Testis Tümörlerinde Cerrahi Tedavi Yöntemleri
Özet
Bu metin, erkeklerde nadir görülen ancak tedavi başarısı oldukça yüksek olan testis kanserinin cerrahi yöntemlerini ele almaktadır. Tanı ve tedavinin temelini oluşturan radikal orşiektomi, inguinal insizyonla testis ve spermatik kordun tamamen çıkarılmasını içerir. Son yıllarda organ koruma amacıyla, 2 cm'den küçük polar yerleşimli tümörlerde ve soliter testisli hastalarda Leydig hücre fonksiyonlarını ve spermatogenezi korumak için parsiyel orşiektomi de uygulanmaktadır. Diffüz metastatik veya semptomatik vakalarda ise sistemik kemoterapi sonrasında gecikmiş orşiektomi önerilir. Testis kanserinin retroperitoneal yayılım eğilimi nedeniyle, evreleme ve tedavi yönetiminde Retroperitoneal Lenf Nodu Diseksiyonu (RPLND) kritik bir role sahiptir. RPLND, açık cerrahi (torakoabdominal veya transabdominal) yöntemlerin yanı sıra günümüzde laparoskopik ve robotik olarak da gerçekleştirilebilmektedir. Ameliyat sırasında ejakülasyonun ve fertilitenin korunması için sinir koruyucu tekniklerin uygulanması büyük önem taşır. Modern kemoterapi ve cerrahi ilerlemeler sayesinde hastalarda kür oranı %90'a ulaşmış olup, temel hedef onkolojik etkinlikten ödün vermeden morbiditeyi en aza indirmek ve yaşam kalitesini artırmaktır.
This text discusses the surgical methods for testicular cancer, a rare malignancy in men with a highly successful treatment rate. Radical orchiectomy, the cornerstone of diagnosis and treatment, involves the complete removal of the testis and spermatic cord via an inguinal incision. In recent years, for organ preservation, partial orchiectomy has been utilized in well-selected cases with polar-located tumors smaller than 2 cm, particularly to preserve Leydig cell functions and spermatogenesis in solitary testis patients. Delayed orchiectomy is recommended following systemic chemotherapy in patients presenting with diffuse metastatic or symptomatic disease. Due to the propensity of testicular cancer to spread retroperitoneally, Retroperitoneal Lymph Node Dissection (RPLND) plays a critical role in staging and management. RPLND can be performed through open surgery (thoracoabdominal or transabdominal approaches) as well as modern laparoscopic and robotic methods. Implementing nerve-sparing techniques during the procedure is highly important to preserve ejaculation and fertility. Thanks to advanced chemotherapy and surgical progress, the cure rate has reached 90%, with the primary goal being to minimize morbidity and enhance quality of life without compromising oncological efficacy.
