Potential benefits of neoadjuvant radiotherapy prior to "en bloc" compartmental resection of pure retroperitoneal liposarcomas.

Retroperitoneal liposarcomas(RPL) are rare malignant tumors, accounting for approximately 15% of soft tissue sarcomas and 0.07-0.2% of all cancers.

French AFU Cancer Committee Guidelines - Update 2024-2026: Upper urinary tract urothelial cancer (UTUC).

Introduction: The purpose of this study was to propose an update of the French guidelines from the national committee ccAFU on upper tract urothelial carcinomas (UTUC).

Methods: A systematic Medline search for epidemiology, risk factors, diagnosis, prognosis, treatment options and follow-up of UTUC was performed between 2022 and 2024 to evaluate available references and their levels of evidence.

Results: UTUC is a rare malignancy with specific risk factors, including exposure to aristolochic acid and Lynch syndrome.

French AFU Cancer Committee Guidelines - Update 2024-2026: Non-muscle invasive bladder cancer (NMIBC).

Objective: To update the CCAFU recommendations for the management of non-muscle invasive bladder cancer (NMIBC).

Methods: A systematic review (Medline) of the literature from 20222024 was performed, taking into account the elements of diagnosis, treatment options and monitoring of NMIBC and evaluating references with their level of evidence.

Results: The diagnosis of NMIBC (Ta, T1, or CIS) is made after complete and deep tumour resection.

French AFU Cancer Committee Guidelines - Update 2024-2026: Muscle-invasive bladder cancer (MIBC).

Objective: To update the CCAFU recommendations for the management of muscle-invasive bladder cancer (MIBC).

Methods: A systematic review (Medline) of the literature from 2022 to 2024 was carried out, taking into account the elements of the diagnosis, the treatment options and the monitoring of NMIBC and MIBC, evaluating the references with their level of evidence.

Results: MIBC is diagosed after the must complete tumor resection possible .

Do we need a re-TUR after en bloc resection of T1 stage bladder cancer?

Background: A second look trans-urethral resection of the bladder (re-TUR) is recommended after the diagnosis of T1 high grade (T1HG) bladder cancer. Few studies have evaluated the results of re-TUR after a first en bloc resection (EBR) and none of them have specifically reported the pathological results on the field of previous T1 disease.

Objective: To report the rate of upstaging and the rate of residual disease (RD) on the field of T1HG lesions resected with EBR.
