Appropriateness of Mini-Invasive Approaches for Nausea and Vomiting Refractory to Medical Therapy in Palliative Care Setting: A Case Report.

Introduction: Nausea and vomiting are frequent multifactorial symptoms in oncological patients. These manifestations, mainly affecting the advanced disease stages, may lead to existential, psychological, and physical suffering, with a negative impact on the quality of life (QoL) of the individual and his family. The medical approach makes use of a wide range of drugs, with different antiemetic potency and various mechanisms of action, taking into account the etiology and the patient's response to the different therapeutic strategies. In recent years, in addition to pharmacological treatments, some endoscopic procedures have been integrated into clinical practice as promising palliative approaches. Case Presentation: Herein, we describe and discuss a case of a 64-year-old female affected by advanced stage pancreatic adenocarcinoma, in which different techniques - both medical and endoscopic - have been used to approach a refractory symptomatology with a negative impact on the patient's QoL. In the context of a multidisciplinary approach in primary palliative care, a tailored intervention encompassing invasive methods for palliative purposes, may be considered adequate and appropriate when the prognostic expectation and the physical functionality indices allow it. Conclusion: Minimally invasive palliative interventions should be offered to patients with advanced cancer when symptoms become refractory to standard medical therapies, as part of the holistic approach in modern treatments. Therefore, the integration of an early palliative approach into the patient's therapeutic path becomes essential for the management of all the individual's needs.

Palliative short-course radiotherapy (RAPASH study) in patients with rectal cancer.

Background: Palliative radiation therapy (RT) is used to treat symptomatic rectal cancer although clinical benefits and toxicities are poorly documented. There is no consensus about the optimal RT regimen and clinical practice undergoes significant changes. Our aim was to evaluate the efficacy and toxicity of short-course (SC) RT in this setting of patients. Materials and methods: Charts from patients with locally advanced disease not candidates for standard treatment or with symptomatic metastatic rectal cancer treated with SCRT (25 Gy/5 fractions in 5 consecutive days) were retrospectively reviewed. Clinical outcome measures were symptomatic response rate and toxicity. Results: From January 2007 to December 2017, 59 patients (median age 80 years) received SCRT; 53 were evaluable. The median follow-up was 8 months (range, 1-70). Clinical response to RT for bleeding, pain and tenesmus was 100%, 95% and 89%, respectively. The compliance with the treatment was 100% and no patient experienced acute severe (≥ grade 3) toxicities. Median time to symptoms recurrence was 11 months (range 3-69). Globally, the median overall survival was 12 months. Conclusions: SCRT is a safe and effective regimen in symptomatic rectal cancer and may be considered the regimen of choice for standard treatment in unfit patients.

Radiotherapy and palliative care outpatient clinic: a new healthcare integrated model in Italy.

BACKGROUND: On the basis of substantial evidence demonstrate that palliative care combined with standard care improves patient, caregiver, and society outcomes, we have developed a new healthcare model called radiotherapy and palliative care (RaP) outpatient clinic were a radiation oncologist and a palliative care physician make a joint evaluation of advanced cancer patients. METHODS: We performed a monocentric observational cohort study on advanced cancer patients referred for evaluation at the RaP outpatient clinic. Measures of quality of care were carried out. RESULTS: Between April 2016 and April 2018, 287 joint evaluations were performed and 260 patients were evaluated. The primary tumor was lung in 31.9% of cases. One hundred fifty (52.3%) evaluations resulted in an indication for palliative radiotherapy treatment. In 57.6% of cases was used a single dose fraction of radiotherapy (8 Gy). All the irradiated cohort completed the palliative radiotherapy treatment. An 8% of irradiated patients received the palliative radiotherapy treatment in the last 30 days of life. A total of 80% of RaP patients received palliative care assistance until the end of life. CONCLUSION: At the first descriptive analysis, the radiotherapy and palliative care model seem to respond to the need of multidisciplinary approach in order to obtain an improvement on quality of care for advanced cancer patients.

Prognostication in palliative radiotherapy-ProPaRT: Accuracy of prognostic scores.

Background: Prognostication can be used within a tailored decision-making process to achieve a more personalized approach to the care of patients with cancer. This prospective observational study evaluated the accuracy of the Palliative Prognostic score (PaP score) to predict survival in patients identified by oncologists as candidates for palliative radiotherapy (PRT). We also studied interrater variability for the clinical prediction of survival and PaP scores and assessed the accuracy of the Survival Prediction Score (SPS) and TEACHH score. Materials and methods: Consecutive patients were enrolled at first access to our Radiotherapy and Palliative Care Outpatient Clinic. The discriminating ability of the prognostic models was assessed using Harrell's C index, and the corresponding 95% confidence intervals (95% CI) were obtained by bootstrapping. Results: In total, 255 patients with metastatic cancer were evaluated, and 123 (48.2%) were selected for PRT, all of whom completed treatment without interruption. Then, 10.6% of the irradiated patients who died underwent treatment within the last 30 days of life. The PaP score showed an accuracy of 74.8 (95% CI, 69.5-80.1) for radiation oncologist (RO) and 80.7 (95% CI, 75.9-85.5) for palliative care physician (PCP) in predicting 30-day survival. The accuracy of TEACHH was 76.1 (95% CI, 70.9-81.3) and 64.7 (95% CI, 58.8-70.6) for RO and PCP, respectively, and the accuracy of SPS was 70 (95% CI, 64.4-75.6) and 72.8 (95% CI, 67.3-78.3). Conclusion: Accurate prognostication can identify candidates for low-fraction PRT during the last days of life who are more likely to complete the planned treatment without interruption.All the scores showed good discriminating capacity; the PaP had the higher accuracy, especially when used in a multidisciplinary way.

Tomotherapy-based moderate hypofractionation for localized prostate cancer: a mono-institutional analysis.

Background: To date, few studies have been published on image-guided helical tomotherapy (HT) in a moderate hypofractionation of localized PCa. We report outcome and toxicity of localized PCa patients treated with HT-based moderate hypofractionated radiotherapy. Materials and methods: 76 patients were retrospectively analyzed. A total dose of 60 Gy (20 × 3 Gy) or 67.5 Gy (25 × 2.7 Gy) was prescribed. The χ2 test was used to analyze associations between toxicity and dosimetric and clinical parameters. The Cox proportional hazard regression model was used for multivariate analysis. Kaplan-Meier method was used for survival analysis. Results: median follow-up was 42.26 months [interquartile (IQR), 23-76). At 4-year, overall survival (OS) and metastasis-free survival (MFS) were 91% and 89%, respectively. At multivariate analysis, smoking habitude was associated with MFS [hazard ratio (HR) 7.32, 95% CI: 1.57-34.16, p = 0.011]. Acute and late grade ≥ 2 gastro-intestinal (GI) toxicity was observed in 6.5% and 2.6% of patients, respectively. Acute and late grade ≥ 2 genito-urinary (GU) toxicity were 31.5% and 3.9%. Four-year late GI and GU grade ≥ 2 toxicity were 3% and 7%, respectively. Acute GI toxicity was associated with statins medication (p = 0.04) and androgen deprivation therapy (p = 0.013). Acute GU toxicity was associated with the use of anticoagulants (p = 0.029) and antiaggregants (p = 0.013). Conclusions: HT-based moderate hypofractionation shows very low rates of toxicity. Smoking habitude is associated with the risk of developing metastases after radical treatment for localized PCa.

Pulmonary function in stereotactic body radiotherapy with helical tomotherapy for primary and metastatic lung lesions.

AIMS: This retrospective study reports outcomes after stereotactic body radiation therapy (SBRT) as delivered by helical tomotherapy (HT) for lung lesions. It promotes a dose escalation program. METHODS: Histological and/or radiological findings and/or case histories identified 41 primary and 15 metastatic lesions. Thirty patients received 40 Gy in 5 fractions (BED 72 Gy10Gy) and 26 50 Gy in 5 fractions (BED 100Gy10Gy). Primary end point was lung toxicity. Secondary end points were respiratory function, local control and local progression-free survival. RESULTS: Acute toxicity developed in 18/56 patients and late toxicity in 8/54. Median FEV-1 variations versus baseline were - 0.5% (range - 16 to + 43%) at 6 months and - 4.00% (range - 42 to + 18%) at 24 months. Median DLCO variations versus baseline were - 1% (range - 38 to + 36%) at 6 months and - 12.2% (range - 48 to + 11%) at 24 months. At 6 months, a significant positive correlation emerged between FEV-1 change and KPS (p = 0.047). At 24 months, a significant negative correlation emerged between FEV-1 change and the ipsilateral lung V5 (p = 0.006). A low baseline DLCO correlated with more marked DLCO worsening at 6 months (p = 0.012). At 24 months, DLCO worsening correlated significantly with the median contralateral lung dose (p = 0.003). At the last checkup, 23 patients were in complete remission, 16 were in partial remission, 5 had stable disease, and 7 were in relapse. Median follow-up was 12 months (range 5-56). CONCLUSIONS: In patients with lung disease, SBRT, as delivered by HT, was well tolerated and provided good local control.
