Cellular Immunity and Renal Cell Cancer

Renal cell cancer (RCC) is one of the most important urogenital tumors because of it's high mortality and increasing incidence. RCC, which accounts about 3% of all malignant tumors in the adults, is the most lethal urogenital cancer. The high mortality rate stimulate investigator groups to study RCC pathogenesis including immunological part. It is interesting that immunotherapy was firstly started in patients with metastatic RCC using IL-2 and interferon gamma. The first results were promising but the exact mechanism of acting was not found. In the RCC, as in the others tumors, immune cells (T lymphocytes, NK and NKT cells) are responsible for main antitumor effect. Their effect was caused by cytotoxic activity on the tumor cells. In the investigation investigators will determine patterns of aggregation of tumor infiltrating immune cells in the blood, healthy kidney and carcinomatous tissue. But, presence of this cells not implicated that this cells are active. Their activity will be determined by proofing cytotoxicity of different subgroup of immune cells. In that way investigators will present different patterns of aggregation of tumor infiltrating immune cells and their cytotoxicity which will direct that this cells are active with antitumor effect. Correlation of collected data with classical prognostic factors in the patients with RCC as tumor staging, tumor grading (Fuhrman) and histological subtype will help to determine some immunological factors as possible new prognostic factors. For conclusion, the results of this study will allow better understanding of RCC pathogenesis, specially their immunological part and become a foundation for the future investigations.

Protocol Active Surveillance Small Renal Masses (SRMs)

Prospective study of active surveillance, non-randomized, multicentric, in asymptomatic patients over the age of 50 years, not affected by other tumors, with occasional diagnosis of single monolateral solid renal mass equal to or less than 2 cm of diameter. Diagnosis will be performed with chest CT abdomen with contrast and / or MRI abdomen with Gadolinium (Gd); during the first year of active surveillance, the patient's status will be evaluated at 3, 6, 9 and 12 months from the diagnosis and, subsequently, according to the schedule of events shown in the table "Event Planning" At the end of the 5 years of follow up, the patient will be entrusted to his / her own treating physician, with indication to perform abdomen and chest x-ray echography every 6 months and thoracic abdomen TAC with contrast and / or MRI abdomen with (Gd) every 2 years up to 10 years from instrumental radiological diagnosis and registration and communication of the possible date of death and cause The primary caregivers and the patient will be contacted annually by the promoter center of the study at the end of the first 5 years of study follow up and the data will be entered in the database by the promoter center. The indication to surgical treatment or ablative treatment will be considered in the following cases: 1. appearance of metastasis 2. increase of the maximum diameter of the renal mass equal to or greater than 4 cm 3. time of doubling of the tumor mass size less than or equal to 12 months 4. appearance of symptoms associated with renal disease (pain, haematuria) 5. appearance of paraneoplastic syndrome (fever, cachexia, hypercalcemia, polycythemia, ranulocytosis) 6. willingness expressed by the patient to undergo surgery or ablative operation In the presence of at least one of the aforementioned criteria, the attending physician can evaluate the possible execution of renal biopsy. The finding of renal biopsy proved negative for neoplasia may allow the continuation of the active surveillance procedure undertaken, independently indi - ding from the presence of one of the above mentioned criteria. If the renal biopsy is negative, the therapeutic decision (continuation of the follow up within the protocol in question, surgery or exit from the protocol) will be agreed between the patient and the patient. In the case of a positive renal biopsy for renal neoplasia, the patient may be a candidate for renal tumorectomy / radical nephrectomy.

Impact of Tumour 1q Gain in French Pediatric and Young Adult Patients With Renal Tumours

French patients with nephroblastoma (Wilms tumour, WT) have been treated for > 40 years according to International Society of Paediatric Oncology (SIOP) protocols with currently 267 centres across 28 countries collaborating internationally within the SIOP Renal Tumour Study Group (RTSG). Over the last decades more than 10,000 children have been prospectively enrolled in SIOP WT studies and trials. This has resulted in more standardised diagnostic procedures, improved risk stratification, and adjusted treatment recommendations for most renal tumours. The treatment of patients with renal tumours according to SIOP protocols include preoperative chemotherapy, surgery (tumour-nephrectomy + node-picking ± metastasectomy) followed by risk- and stage-based postoperative chemotherapy ± radiotherapy. Central pathology review is nowadays routinely performed in order to prevent misclassification of stage and histology risk group. The current SIOP 2001 protocol has come to an end with as major achievement the scientific proof of omitting doxorubicin in stage II and III patients with as a consequence less risk of sequelae. Moreover, in the SIOP 2001 protocol, several tumour biological aspects have been assessed that seem to interfere with outcome (chromosomal gain of 1q, or loss of 1p and 16q, blastemal residual volume). Chromosomal 1q gain is considered to be present in 25-35% of patients with nephroblastoma with a negative impact on event-free survival (EFS) in retrospective analyses. These biological aspects will be studied prospectively as a primary objective in the new SIOP RTSG 2016 UMBRELLA protocol that integrates diagnostics, treatment and follow-up guidelines as well as several research projects. The main mission of the International Society of Paediatric Oncology (SIOP) Renal Tumour Study Group (RTSG) is to increase survival and to reduce acute treatment toxicity and late effects in all children diagnosed with any renal tumour. In this context, SIOP RTSG is aiming to offer all these patients the same standardized high quality diagnostics and treatment, independent of the tumour type. The new SIOP RTSG 2016 integrated diagnostic and research UMBRELLA protocol serves as an entry for including all children with a renal tumour in the SIOP-RTSG centers, including prospective biomarker analyses. Subsequently, treatment is recommended according to the SIOP RTSG 2016 UMBRELLA treatment guidelines, which provides treatment strategies for all patients with Wilms tumour (WT) and other renal tumours. Central radiology review (CRR) has been proposed as a novel tool within the diagnostic UMBRELLA protocol in order to optimize the diagnostics and hence the treatment. The definition of metastatic disease in WT remains difficult since pulmonary nodules may not always be of malignant origin. The differential diagnosis of a pulmonary lesion seen in a child with WT is broad. In addition to malignancy, it includes atelectasis, fibrosis, pneumonitis, subpleural lymph nodes, and other infectious or inflammatory lesions. In addition, the issue of "CT-only" nodules in WT and adequate treatment needs to be solved. In previous protocols, the treatment strategy was based on the diagnosis of pulmonary metastases (92% of all metastases) by conventional pulmonary X-ray. Patients with CT-only nodules (= nodules not visible on conventional X-ray) were supposed to be treated as having localized WT. However, retrospective analyses of SIOP series (Smets et al), showed that patients with CT-only nodules had a less favourable prognosis as compared to patients with truly localized disease with a 12% difference in three-year event-free survival. The diagnostics of bilateral renal tumours (stage V) often is complicated since it may be difficult to distinguish true WT from nephroblastomatosis/ nephrogenic rests, a pre malignant renal (multifocal) anomaly, which may respond to preoperative chemotherapy. An optimal multi-disciplinary sequential diagnostic procedure is required in order to propose the best adapted therapeutic approach to preserve sufficient renal tissue.
