10-yr Results of Moderately Hypofractionated Postoperative Radiotherapy for Prostate Cancer Focused on Treatment Related Toxicity.

INTRODUCTION: To retrospectively report long term outcomes following postoperative hypofractionated radiotherapy (RT) for prostate cancer, emphasizing treatment related toxicity. MATERIAL AND METHODS: Patients for whom adjuvant or salvage RT was indicated after prostatectomy were treated with a course of moderate hypofractionation consisting in the delivery of 62.5 Gy in 25 fractions (2.5 Gy per fraction) on the prostate bed in 5 consecutive weeks (EQD21.5 = 70 Gy) by means of 3D-CRT in most of them. Androgen deprivation therapy (ADT) was allowed at physician's discretion. Patients were evaluated for urinary and rectal complications according to the Common Terminology Criteria for Adverse Events v4 (CTCAE v.4). Overall survival (OS), biochemical recurrence free survival (bRFS), and metastasis-free survival (MFS) were estimated using the Kaplan-Meier method. RESULTS: One hundred and ten patients with a median age of 67 years (range 51-78) were enrolled. The majority of them (82%) had adverse pathologic features only, while 31 (28%) had early biochemical relapse. Median PSA level before RT was 0.12 ng/mL (range 0-9 ng/mL). Median time from surgery was 4 months (range 1-136 months). Twenty-eight patients (25.4%) also received ADT. At a median follow up of 103 months (range 19-138 months), late Grade 3 and Grade 4 rectal toxicity were 0.9% (1 case of hematochezia) and 0.9% (1 case of fistula), respectively, while late Grade 3 GU side effects (urethral stenosis) occurred in 9 cases (8%). No late Grade 4 events were observed, respectively. Ten-year OS, b-RFS and MFS were 77.3% (95%CI: 82.1%-72.5%), 53.3% (95%CI: 59.9%-47.6%), and 76.7% (95%CI: 81.2%-72.2%), respectively. CONCLUSION: Our study provides long term data that a shortened course of postoperative RT is as safe and effective as a long course of conventionally fractionated RT and would improve patients' convenience and significantly reduce RT department workloads.

Smile InTM Totems in Radiotherapy: Patients' Satisfaction with Limited Equipment and COVID-19.

BACKGROUND: We report a mono-institutional experience regarding patient-perceived quality regarding the Chieti Radiotherapy Department, through RAMSI (Radiotherapy Amica Mia-SmileINTM(SI)-My Friend RadiotherapySI) project, in critical scenarios of limited equipment and COVID-19. MATERIAL AND METHODS: Patient-reported experience measures (PREMs) were assessed as follows: Patient-centric welcome perception (PCWP), Comfort, Professional skills and Punctuality. Patients could give anonymous feedback using HappyOrNot technology through four totems located in strategic areas within the center. An internal benchmark was obtained using the feedback received after a preliminary observation period. The SI Experience Index was collected, analyzed and compared. Weekly and monthly reports were generated. RESULTS: From February 2019 to February 2022, 8924 patients accessed the department; 17,464 daily treatments were recorded and 5830 points of feedback were collected: 896, 1267, 1125 and 2542 for PCWP, Comfort, Professional skills and Punctuality, respectively. A LINAC decommissioning period was analyzed, with decreases in the SI-Index score and Smile-IN approved percentage and an improvement after this period. Additionally, the COVID-19 pandemic was analyzed with a mild evaluations decrease for PREM's Welcome, Comfort and Punctuality (Δ-value: -9%, -3% and -4%, respectively), while Professional skills were always optimal. CONCLUSION: The RAMSI project was effective for assessing treatment quality perception, allowing for improving clinical procedures with corrective actions. The RAMSI project is ongoing.

Whole breast radiotherapy in cN0 early breast cancer patients with pathological sentinel lymph nodes (pN1mic, pN1a) without axillary dissection: preliminary results of the observational LISEN trial.

PURPOSE: Axillary management remains unclear when sentinel lymph node (SLN) results are positive in cN0 patients with breast cancer (BC). The trial ACOSOG Z0011 represented a revolution with axillary lymph node dissection (ALND) omission in SLN+ patients, despite critiques regarding non-uniformity of radiation fields. We conducted an observational study (LISEN) where whole breast radiotherapy (WBRT) was planned with tangential fields without nodal irradiation in patients eligible for the Z0011 trial. METHODS: Inclusion criteria were female patients with histologically proven BC, cT1-2cN0, planned conservative surgery, no neoadjuvant therapy. Patients were stratified into two groups: micrometastatic (pN1mic, group 1) and macrometastatic (pN1a, group 2) lymph nodes. Tangential field WBRT was mandatory. Clinical outcomes were analysed, measured from surgery until the first event. RESULTS: In all, 199 patients underwent conservative surgery and SLN biopsy; 133 patients meeting criteria were analysed: 41 patients (30.8%) pN1mic and 92 (69.2%) pN1a. The 5­year disease-free survival (DFS) was 95.0% (85.9-100%) in group 1 and 93.0% (86.3-100.0%) in group 2 (p = 0.78). Overall survival (OS) was 100% (100-100%) in group 1 and 97.4% (92.4-100%) in group 2 (p = 0.74). For the whole cohort DFS and OS were 93.6% (88.2-99.4%) and 96.9% (91.5-100.0%), respectively. For groups 1 and 2, the 5­year outcomes were 5.0% (0.0-14.4%) and 2.3% (0.0-6.1%) for local recurrence (p = 0.51), and 6.2% (0.0-17.4%) and 7.0% (0.0-13.7%) for distant metastasis (p = 0.61), respectively. In group 1, regional recurrence (RR) and local regional recurrence (LRR) were 5.0% (0.0-14.1%; p = 0.13). In group 2, RR and LRR were 0.0% (0.0-0.0%). CONCLUSION: Our results showed good regional control in patients who met the Z0011 trial criteria. WBRT, without nodal surgery or RT, avoiding axillary morbidity, seems to be a good choice.

Lower Bladder Toxicity of Salvage Versus Adjuvant Modern Radiotherapy for Prostate Cancer Patients.

BACKGROUND/AIM: In prostate cancer, postoperative radiotherapy timing is debated to avoid overtreatments and toxicities. This study compared acute and late rectal and bladder toxicities in the adjuvant and salvage setting. PATIENTS AND METHODS: In total, 129 patients were analyzed in two groups: adjuvant radiotherapy (aRT) and salvage radiotherapy (sRT). RESULTS: In aRT and sRT, grade 1 (G1) acute bladder toxicities were detected in 40 and 30 patients, and grade 2 (G2) in 1 and 6; G1 late bladder toxicities were described in 30 and 20, and G2 in 6 and 2, respectively. In aRT and sRT, acute G1 rectal toxicities were reported in 18 and 27 patients, and G2 in 5 and 4, respectively. Late rectal G1 toxicities were observed in 10 patients, G2 in 6 and G3 in 1 in the aRT. In sRT, 8 patients and 1 developed G1 and G2 toxicities, respectively. Regarding bladder toxicity, a higher incidence occurred in aRT; late toxicity was lower in sRT. CONCLUSION: Adjuvant and salvage RT in prostate cancer treatment resulted in acceptable toxicities.

Quality of Life in Early Breast Cancer Patients: A Prospective Observational Study Using the FACT-B Questionnaire.

BACKGROUND/AIM: Quality of life (QoL) in early breast cancer (BC) treatment may be affected by acute and late toxicities. This study evaluated the impact of radiotherapy (RT) schedules, treatment-related toxicities, hormone therapy (HT) and age on QoL. PATIENTS AND METHODS: Ninety-five patients answered the FACT-B 4.0 questionnaire. Acute or late toxicities were recorded at each follow-up visit. RESULTS: The median trend of the QoL subscales was stable during all questionnaires. HT negatively impacted on Functional Assessment of Cancer Therapy-General-Total, functional and emotional wellbeing. No difference was recorded between RT schedules and toxicity. No significant differences for age were detected in QoL. CONCLUSION: RT seems not to influence QoL of BC patients, in terms of fractionation regimen or RT-related side-effects. Moreover, women having systemic HT experienced a QoL worse than patients treated with RT only. Further and long-term protocols are needed to improve the validity of the tool.

Multimodal Evaluation of Voice Outcome in Early Glottic Cancers Treated With Definitive Radiotherapy.

Background/Aim: We employed a multimodal evaluation of voice outcome (MEVO) model to assess long-term voice outcome in early glottic cancer (EGC) patients treated with primary radiotherapy (RT). The model consisted of objective and subjective vocal evaluation during follow-up, by a dedicated Speech Pathologist and Speech Therapist. Patients and Methods: MEVO methodology includes Self-perception Voice Handicap Index (VHI-30), evaluation of parameters Grade (G), Roughness (R), Breathiness (B), Asthenia (A) and Strain (S) according to GRBAS scale, objective analysis and aerodynamics using the PRAAT software and laryngeal evaluation with videostroboscope (VS). Results: The MEVO methodology was described and tested on a sample of 10 EGCs submitted to definitive RT (total dose 66-70 Gy). Mean follow-up was 48.9 months (range=9-115). VHI was mild-moderate in 90% of patients; overall voice function (GRBAS) was normal-mildly impaired in 70% of patients; VS evaluation showed normal vocal cord motion in 90% of patients, but complete glottic closure in 60%. PRAAT scores confirmed these findings. Conclusion: A multidimensional voice evaluation is time consuming, but useful to objectify vocal impact of radiotherapy. The MEVO model allowed to quantify vocal dysfunction, showing a good objective vocal outcome.

COVID-19 and radiation oncology: the experience of a two-phase plan within a single institution in central Italy.

BACKGROUND: COVID-19 in Italy has led to the need to reorganize hospital protocols with a significant risk of interruption to cancer treatment programs. In this report, we will focus on a management model covering the two phases of the COVID-19 emergency, namely lockdown-phase I and post-lockdown-phase II. METHODS: The following steps were taken in the two phases: workload during visits and radiotherapy planning, use of dedicated routes, measures for triage areas, management of suspected and positive COVID-19 cases, personal protective equipment, hospital environments and intra-institutional meetings and tumor board management. Due to the guidelines set out by the Ministry of Health, oncological follow-up visits were interrupted during the lockdown-phase I; consequently, we set about contacting patients by telephone, with laboratory and instrumental exams being viewed via telematics. During the post-lockdown-phase II, the oncological follow-up clinic reopened, with two shifts operating daily. RESULTS: By comparing our radiotherapy activity from March 9 to May 4 2019 with the same period in 2020 during full phase I of the COVID-19 emergency, similar results were achieved. First radiotherapy visits, Simulation Computed Tomography and Linear Accelerator treatments amounted to 123, 137 and 151 in 2019 compared with 121, 135 and 170 in 2020 respectively. There were no cases of COVID-19 positivity recorded either in patients or in healthcare professionals, who were all negative to the swab tests performed. CONCLUSION: During both phases of the COVID-19 emergency, the planned model used in our own experience guaranteed both continuity in radiotherapy treatments whilst neither reducing workload nor interrupting treatment and, as such, it ensured the safety of cancer patients, hospital environments and staff.
