OBJECTIVE The value of salivary gland scintigraphy (SGS) in the evaluation of Sjögren’s syndrome (SS) remains controversial. The aim of this study was to evaluate the diagnostic efficacy of quantitative SGS in patients with xerostomia and to assess the correlation between scintigraphic parameters and pathological features of salivary glands. Pelabresib mouse METHODS Medical records of 165 patients with xerostomia who underwent [99mTc] pertechnetate SGS and labial biopsy were retrospectively reviewed. The maximum accumulation ratio (MAR), maximum secretion ratio (MSR), and time interval from stimulation to minimum count (Tmin) of the parotid glands were calculated to quantify the glandular activity. Furthermore, pre-stimulatory oral activity index (PRI) and post-stimulatory oral activity index (POI) were calculated to quantify the oral activity. RESULTS All parameters except for Tmin were significantly lower in patients with SS than in those without SS. Among the five SGS parameters, PRI showed the highest areas under the curve value (0.9005; p  32.75 was associated with a sensitivity of 78.5% and specificity of 86.4% for the diagnosis of SS. A decrease in MAR, MSR, PRI, and POI and an increase in Tmin correlate significantly with the histopathologic grade of labial gland biopsy and disease severity of SS. No significant differences in glandular parameters (MAR, MSR, and Tmin) were found between the non-SS and early-stage SS groups. CONCLUSION Conventional scintigraphic parameters could be used as simple, reliable, and sensitive indicators for the early diagnosis of SS and determination of disease severity.A 75-year-old man was referred to our hospital due to a huge pancreatic cyst. Computed tomography revealed a monocular cyst 15 cm in size without a solid mass lesion nearby. He was diagnosed with pancreatic pseudocyst. Endoscopic ultrasound (EUS)-guided drainage was planned for the next day due to abdominal distension; however, the pseudocyst ruptured into the peritoneal cavity before treatment could be applied. To prevent the progression of peritonitis, EUS-guided drainage of the pseudocyst was performed. A nasocystic tube and plastic stent were placed into the ruptured cyst via the gastric wall through the same puncture tract. After the treatment, the cyst rapidly decreased in size, and the peritonitis improved without surgery. The patient’s serum IgG4 level was found to be elevated to 820 mg/dL. Endoscopic retrograde cholangiopancreatography revealed main pancreatic duct stricture without obstruction. No communication between the main pancreatic duct and the pseudocyst was found. An EUS-guided fine-needle aspiration biopsy of the hypoechoic site was performed, revealing IgG4-positive plasma cell infiltration. He was finally diagnosed with AIP associated with the rupture of a pseudocyst. Oral corticosteroid (30 mg/day) treatment was started and gradually tapered. There has been no recurrence in the 28 months since the initiation of treatment.AIMS To investigate the present attitude of the Italian Radiation Oncologists in the management of breast cancer (BC) concerning hypofractionated radiotherapy (hRT), partial-breast irradiation (PBI), re-irradiation (rRT) and radiotherapy after neoadjuvant chemotherapy (post-NAC RT). METHODS A nationwide, 21-point questionnaire was distributed online via SurveyMonkey. RESULTS Seventy-four Italian Radiotherapy Centers answered to the survey. In most cases, the responding centers treated more than 100 BC patients/year between January 2016 and December 2017. Almost half of responding centers (49%) treated patients with hRT, out of these, 95% as routine practice for early-stage BC. Dose prescriptions ranged between 39 and 45 Gy indicating a high use of moderate hRT. The chest wall and regional lymph nodes were irradiated with hRT by 13% and 15% of the responding centers, respectively. PBI was used by 60% of responders, with different techniques. Only 0.6% of participants perform rRT after BC recurrence. Finally, only 11% of the interviewed centers responded to their attitude toward post-NAC RT, which, however, was indicated in 97% of patients after breast-conserving surgery. CONCLUSIONS This survey shows a fairly good use of hRT and a moderate practice of PBI in Italy. Some practices like hRT to the chest wall and regional lymph nodes as well as rRT need further verification. Likewise, the management of post-NAC RT is very heterogeneous. Future national clinical collaborative studies are advocated in order to investigate these controversial topics about breast cancer radiotherapy.AIM The aim of our study was to evaluate the sensitivity of contrast-enhanced magnetic resonance (CE-MR) with phased array coil in the diagnosis of local recurrence in patients with prostate cancer after radical prostatectomy and referred for salvage radiotherapy (SRT). MATERIALS AND METHODS This retrospective study included 73 patients treated with SRT after radical prostatectomy in the period between September 2006 and November 2017. All patients performed a CE-MRI with phased array coil before the start of SRT. A total of 213 patients treated at the ASST Grande Ospedale Metropolitano Niguarda in the period between September 2006 and November 2017 with SRT after radical prostatectomy were reviewed. Seventy-three patients with a CE-MRI with phased array coil of the pelvis before the start of SRT were included in the present study. RESULTS At imaging review, recurrence local recurrent disease was diagnosed in 48 of 73 patients. By considering as reference standard the decrease in prostate-specific antigen (PSA) value after radiotherapy, we defined 41 true positive (patients with MRI evidence of local recurrence and PSA value decreasing after SRT), 7 false positive (patients with MRI evidence of local recurrence without biochemical response after SRT), 3 true negative (patients without MRI evidence of local recurrence and stable or increased PSA value after SRT) and 22 false negative (patients without MRI evidence of local recurrence and PSA value decreasing after SRT) cases. The sensitivity values were calculated in relation to the PSA value before the start of treatment, obtaining a value of 74% for PSA above 0.2 ng/mL. CONCLUSION The sensitivity of CE-MRI in local recurrence detection after radical prostatectomy increases with increasing PSA values. CE-MRI with phased array coil can detect local recurrences after radical prostatectomy with a good sensitivity in patients with pre-RT PSA value above 0.2 ng/mL.
