Unifocality as Prognostic Factor for Unilateral Retinoblastoma: Preliminary Results of 32 Eyes Treated with Intra-Arterial Chemotherapy Alone

Purpose: To evaluate the role of intra-arterial chemotherapy (IAC) in the management of unilateral, unifocal retinoblastoma (RB) as a single therapy, associated to neither focal nor systemic adjunctive therapies. Methods: Prospective, single center, interventional case series of 32 consecutive eyes diagnosed with unilateral unifocal RB and treated exclusively with selective ophthalmic intra-arterial chemotherapy, with no adjunctive systemic or focal treatments. Results: Full regression of the lesion was observed in 30 eyes (93.75%). 2 eyes were enucleated. Ophthalmoscopic remissions type I and III with higher calcific component were achieved. Additionally, neither recurrences nor new tumors appeared during the patient follow-up, which ranged from 10 months to 13 years. Conclusion: Selective intra-arterial chemotherapy has demonstrated to be highly effective in terms of disease control and anatomical preservation in case of unilateral unifocal disease, without requiring any additional systemic and/or focal therapy

Structured and shared CT radiological report of gastric cancer: a consensus proposal by the Italian Research Group for Gastric Cancer (GIRCG) and the Italian Society of Medical and Interventional Radiology (SIRM)

Objectives Written radiological report remains the most important means of communication between radiologist and referring medical/surgical doctor, even though CT reports are frequently just descriptive, unclear, and unstructured. The Italian Society of Medical and Interventional Radiology (SIRM) and the Italian Research Group for Gastric Cancer (GIRCG) promoted a critical shared discussion between 10 skilled radiologists and 10 surgical oncologists, by means of multi-round consensus-building Delphi survey, to develop a structured reporting template for CT of GC patients. Methods Twenty-four items were organized according to the broad categories of a structured report as suggested by the European Society of Radiology (clinical referral, technique, findings, conclusion, and advice) and grouped into three "CT report sections" depending on the diagnostic phase of the radiological assessment for the oncologic patient (staging, restaging, and follow-up). Results In the final round, 23 out of 24 items obtained agreement ( >= 8) and consensus ( 0.05). Conclusions The structured report obtained, shared by surgical and medical oncologists and radiologists, allows an appropriate, clearer, and focused CT report essential to high-quality patient care in GC, avoiding the exclusion of key radiological information useful for multidisciplinary decision-making

Gastric Cancer Maximum Tumour Diameter Reduction Rate at CT Examination as a Radiological Index for Predicting Histopathological Regression after Neoadjuvant Treatment: A Multicentre GIRCG Study

Aim. To investigate the role of maximum tumour diameter (D-max) reduction rate at CT examination in predicting histopathological tumour regression grade (TRG according to the Becker grade), after neoadjuvant chemotherapy (NAC), in patients with resectable advanced gastric cancer (AGC). Materials and Methods. Eighty-six patients (53 M, mean age 62.1 years) with resectable AGC (≥T3 or N+), treated with NAC and radical surgery, were enrolled from 5 centres of the Italian Research Group for Gastric Cancer (GIRCG). Staging and restaging CT and histological results were retrospectively reviewed. CT examinations were contrast enhanced, and the stomach was previously distended. The D-max was measured using 2D software and compared with Becker TRG. Statistical data were obtained using “R” software. Results. The interobserver agreement was good/very good. Becker TRG was predicted by CT with a sensitivity and specificity, respectively, of 97.3% and 90.9% for Becker 1 (D-max reduction rate > 65.1%), 76.4% and 80% for Becker 3 (D-max reduction rate < 29.9%), and 70.8% and 83.9% for Becker 2. Correlation between radiological and histological D-max measurements was strongly confirmed by the correlation index (c.i.= 0.829). Conclusions. D-max reduction rate in AGC patients may be helpful as a simple and reproducible radiological index in predicting TRG after NAC
