The Effect of Video-Based Education on Anxiety of Patients Receiving Stereotactic Radiosurgery and Stereotactic Body Radiation Therapy.

Patients receiving stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) may have an anxiety due to unknown aspects of the treatment. We aimed to reduce patient anxiety by using video-based education. Forty patients were divided into 2 groups, with one-to-one information session (n = 20) and one-to-one information session plus video-based education (n = 20). The patients completed the State-Trait Anxiety Inventory (STAI) and visual facial anxiety scale before and after information sessions and after treatment. The setup time and disruptions during treatment sessions were recorded for patients receiving treatment with Novalis® and Cyberknife®, respectively. The patient characteristics and STAI scores before education were similar between groups. The anxiety level was significantly lower in group 1 after treatment (median 38, interquartile range (IQR) 27-45) compared to before (median 43, IQR 36-47) (p = 0.003) and after information sessions (median 42, IQR 36-47) (p = 0.004); however, any difference was not observed in anxiety levels between before and after information sessions (p = 0.317). The anxiety level was significantly lower in group 2 after video-based education (median 25, IQR 22-33) and after treatment (median 25, IQR 20-30) compared to before video-based education (median 35, IQR 31-42) (p < 0.001 for both), while there was no significant difference in anxiety levels between after video-based education and after the treatment (p = 0.407). The interruptions during treatment were observed in 9 (60%) patients in group 1 and 6 (40%) patients in group 2 (p = 0.038). Video-based educations significantly reduce patient anxiety before SRS/SBRT and increase their compliance with the treatment.

Gemcitabine based trimodality treatment in patients with muscle invasive bladder cancer: May neutrophil lymphocyte and platelet lymphocyte ratios predict outcomes?

PURPOSE: Cisplatin based chemoradiation has been commonly used as a definitive treatment for muscle-invasive bladder cancer (MIBC). The aim of the current study is to evaluate oncologic results and toxicity profile of bladder-sparing treatment with external beam radiotherapy (EBRT) and gemcitabine chemotherapy (ChT) in patients with MIBC. MATERIALS AND METHODS: Between April 2005 and November 2018 44 patients with nonmetastatic and N0 MIBC were treated with transurethral resection of bladder (TURB), EBRT and concurrent gemcitabine. All patients were staged using thorax-abdomen-pelvic CT and pelvic MRI. EBRT was delivered using 3D conformal technique or intensity modulated radiotherapy. Patients received 50 Gy in 25 to 28 fractions to full bladder followed by a boost dose of 10 Gy in 5 fractions to empty bladder with weekly concurrent gemcitabine of 50 mg/m2. All patients were evaluated for age, gender, smoking status, neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) at diagnosis, presence of hydroureteronephrosis (HUN), preoperative tumor size, tumor multifocality, presence of CIS, clinical tumor stage. Acute/late genitourinary (GUS) and gastrointestinal (GIS) toxicity, recurrence status, cancer specific survival (CSS) and overall survival (OS) were evaluated. Statistical analysis was performed using SPSS v21.0. Kaplan-Meier survival estimates were calculated to describe CSS and OS. The effect of different parameters on survival was investigated using the log rank test. RESULTS: Median age of the patients was 72 years (interquartile [IQR]; 66-80). The median tumor size was 30 mm (IQR, 15-59 mm). Thirty-two (77%) patients had T2, 6 (14%) patients had T3, and 4 (9%) patients had T4a disease. Median NLR was 2.6 (IQR, 1.7-3.8) and median PLR was 126.47 (IQR, 77.4-184.8). Median follow-up time was 21 months (range, 6-153 months). At the first TURB performed 6 weeks after CRT, complete response, partial response, stable disease, and progression was detected in 37 (84%), 3 (7%), 1 (2%), and 3 (7%) patients, respectively. One- and 2-year OS, CSS, LRFS, and DMFS rates were 86% and 64%; 88% and 66%; 65% and 44%; 68% and 48%, respectively. In univariate analysis; prognostic factors were age and presence of HUN for OS and DMFS; age, HUN, presence of CIS, NLR, and PLR for DSS; HUN, NLR, and PLR for LRFS, respectively. In multivariate analysis, the independent predictor was the presence of HUN for OS, LRFS, and DMFS; NLR for DSS; PLR for LRFS and age for DMSF. For a subgroup of 17 patients with complete TURB and no CIS and HUN symptoms, 2-year OS, DSS, LRFS, and DMFS rates were 88%, 88%, 72%, and 79%, respectively. The treatment was well-tolerated and all patients completed the planned EBRT and ChT. No acute or late ≥ grade 3 toxicity was observed. Grade II acute GIS toxicity was detected in 3 (7%) patients and grade II acute GUS toxicity was detected in 9 (21%) patients, respectively. Grade II late GUS toxicity was observed in 2 (5%) patients. CONCLUSION: Gemcitabine based trimodality treatment is well-tolerated with similar oncologic outcomes reported in the literature. Older age, presence of CIS and high NLR and PLR values seem to deteriorate DSS.

Factors affecting post-treatment radiation-induced lung disease in patients receiving stereotactic body radiotherapy to lung.

The aim of the study is to investigate factors that may cause radiation-induced lung disease (RILD) in patients undergoing stereotactic body radiotherapy (SBRT) for lung tumors. Medical records of patients treated between May 2018 and June 2019 with SBRT were retrospectively evaluated. All patients should have a diagnosis of either primary non-small cell lung cancer (NSCLC) or less than three metastases to lung from another primary. The median treatment dose was 50 Gy in 4-5 fractions. Tumor response and RILD were evaluated in thoracic computer tomography (CT) using RECIST criteria. 82 patients with 97 lung lesions were treated. The median age was 68 years (IQR = 62-76). With a median follow-up of 7.2 months (3-18 months), three patients had grade 3 radiation pneumonitis (RP). RILD was observed in 52% of cases. Patients who had RILD had a higher risk of symptomatic RP (p = 0.007). In multivariate analyses older age, previous lung radiotherapy history, and median planning treatment volume (PTV) D95 value of ≥ 48 Gy were associated with RILD. Local recurrence (LR) was observed in 5.1% of cases. There was no difference in overall survival and LR with the presence of RILD. Older age, previous lung radiotherapy history, and median PTV D95 value of ≥ 48 Gy seems to be associated with post-SBRT RILD.

Using a pessary during radiotherapy in reducible pelvic organ prolapse and vaginal cancer: a case report and review of the literature.

PURPOSE: Primary vaginal cancer and pelvic organ prolapse (POP) combination is extremely rare. Although definitive chemoradiotherapy (CRT) and brachytherapy (BT) is the standard treatment for advanced stage primary vaginal cancer, there is a limited data about the treatment of primary vaginal cancer combined with POP due to its rarity. In addition, radiotherapy (RT) process may be difficult in these cases and often result in more toxicity. CASE PRESENTATION: In this case report, we present a 77-year-old woman with a diagnosis of primary vaginal cancer associated with POP, who was treated with definitive CRT using a pessary to restore vaginal anatomy for optimal radiation. Following CRT, complete response was observed and vaginal cuff BT was performed. The patient tolerated the treatment very well and is still alive without disease at 10-months follow-up. CONCLUSIONS: Combined primary vaginal cancer and POP is an extremely rare clinical entity, with only a few cases reported in the literature. When applying CRT in these cases, critical organ doses may be higher than expected due to the downward descent of the pelvic organs. Especially in elderly patients, a pessary can be used as a non-surgical procedure to restore the anatomy for symptom relief during definitive CRT. Additionally, it allows tumors to be targeted more precisely.
