Primitive retroperitoneal tumors are formations with varying degrees of severity. They may occur locally, being impressive due to their generous diameters, but they can also invade the entire body. The latest genetic studies have somewhat changed the vision about the etiology of soft tissue tumors, while the immunohistochemical studies offer customized results on recurrence, metastasis and surv...

Gastric cancer is the most common malignancy and the incidence is steadily increasing in Korea. The principal treatment modality for gastric cancer is surgical extirpation of tumor along with draining lymph nodes. Gastrectomy with D2 lymph node dissection has been well established as a standard of surgery and improved the survival of gastric cancer patients. Recently, technological advances are...

BACKGROUND Malignant germ cell tumours represent the vast majority of palpable testicular masses, and radical orchiectomy is still considered the standard-of-care. Testis-sparing surgery (TSS) could be an alternative to radical orchiectomy in patients diagnosed with small testicular masses (STMs). The aim of this article was to review the current indications and the oncological and functional o...

INTRODUCTION The treatment of rectal cancer via laparoscopy is controversial due to its technical complexity. Several randomized prospective studies have demonstrated clear advantages for the patient with similar oncological results to those of open surgery, although during the learning of this surgical technique there may be an increase in complications and a worse prognosis. OBJECTIVE Our a...

Analysis of variance (ANOVA) is a statistical method that is widely used in the psychosomatic literature to analyze the results of randomized trials, yet ANOVA does not provide an estimate for the difference between groups, the key variable of interest in a randomized trial. Although the use of ANOVA is frequently justified on the grounds that a trial incorporates more than two groups, the hypo...

Autologous fat graft to the breast is a useful tool to correct defects after breast conservative treatment (BCT). Although this procedure gains popularity, little is known about the interaction between the fat graft and the prior oncological environment. Evidences of safety of this procedure in healthy breast and after post-mastectomy reconstruction exist. However, there is paucity of data amon...

While open thyroidectomy (OT) is advocated as the gold standard treatment for differentiated thyroid cancer, the contemporary use of robotic thyroidectomy (RT) is often controversial. Although RT combines the unique benefits of the surgical robot and remote access thyroidectomy, its applicability on cancer patients is challenged by the questionable oncological benefits and safety. This review a...

Testis-sparing surgery (TSS) represents a therapeutic choice for testicular cancer (TC). However, international guidelines are very cautious about the use of the testis-sparing technique, namely due to the lack of certain indications and long-term oncological outcomes. The aim of this systematic-review is to illustrate current trends of what may today be the uses of organ-sparing surgery in TC,...
