PURPOSE: This study was initiated to prove feasibility of hydrogel application in recto-vaginal space in intracavitary brachytherapy (ICBT) of cervical cancer in order to reduce rectal toxicity. MATERIAL AND METHODS: In a case of stage IIB cervical cancer, after external beam radiotherapy (EBRT), we planned ICBT 7 Gy × 3 fractions. In 1(st) fraction (Plan 1), due to narrow separation between rectum and cervix (0.18 cm), only 5 Gy was delivered at point A (with high-risk clinical target volume [HR-CTV] D90 5...

BACKGROUND: Prostate cancer (PCa) is the most commonly diagnosed malignancy in men and the second leading cause of cancer death in developed countries. Despite the primary treatments, 20-30% of patients experience a recurrence. The main objective of this study was to evaluate the clinical efficacy of salvage HIFU after radical prostatectomy in terms of biochemical free survival rate (BFSR) and PSA nadir. METHODS: Twenty two patients with local recurrence of Pca after radical prostatectomy underwent HIFU as first-line salvage therapy...

INTRODUCTION: Emphysematous epididymo-orchitis is a rare cause of acute scrotum pain characterized by gas formation within the tissue. Diabetes mellitus and recto-seminal fistula secondary to sigmoid diverticulitis are generally accepted as being responsible for this disease. However, prostate invasion secondary to rectal cancer may be considered to be a newly identified pathogenetic mechanism. Herein, we report this rare case and illustrate the pathogenesis. CASE PRESENTATION: A 69-year-old man arrived at our emergency department presenting with sepsis and acute scrotal pain...

OBJECTIVE: To describe the management of grade 4 Radiation Therapy Oncology Group (RTOG) urinary adverse events (UAEs) after radiotherapy (RT) for prostate cancer (PCa). We hypothesized grade 4 UAEs often require complex surgical management and subject patients to significant morbidity. METHODS: A single-center retrospective review, over a 6-year period (2010-2015), identified men with RTOG grade 4 UAEs after RT for PCa. RT was classified as combined modality therapy (radical prostatectomy (RP) followed by external beam radiotherapy (EBRT), EBRT + low-dose brachytherapy (LDR), EBRT + high-dose brachytherapy (HDR), or other combinations of RT) or single modality RT...

A 62-year-old woman was admitted to our hospital because of bloody stool. Colonoscopy revealed stenosis by a type 2 tumor of the recto-sigmoid colon. A biopsy specimen contained moderately differentiated adenocarcinoma. Thoraco-abdominal computed tomography (CT) showed liver metastasis (S7, 10 mm) and enlargement of Virchow's lymph node (17 mm) and several para-aortic lymph nodes (15 mm on average). Because of oozing from the tumor and severe stenosis of the recto-sigmoid colon, we performed laparoscopic-assisted high anterior resection of the primary lesion...

AIM: Dissection of the perineal body (PB) during abdominoperineal excision (APE) for low rectal cancer is often difficult due to the lack of a natural plane of dissection. Understanding the PB and its relation to the anorectum is essential to permit safe dissection during the perineal phase of the operation and avoid damage to the anorectum and urogenital organs. This study describes the anatomy and histology of the PB relevant to APE. METHOD: Six human adult cadaver pelvic exenteration specimens (three male, three female) from the Leeds GIFT Research Tissue Programme were studied...
