Health-related quality of life (HRQoL) from HIV patients' perspective: comparison of patient-reported outcome (PRO) measures among people living with hiv (PLWH) and other chronic clinical conditions.

BACKGROUND: People living with HIV (PLWH) are generally known to suffer from a lower quality of life compared to the one of general population, but still very few is known about the self-perception of quality of life when comparing HIV to non-communicable diseases. We performed a comprehensive assessment of patient's reported outcomes measures (PROMs) among PLWH and patients affected by other chronic conditions (OC) such as diabetes mellitus type 1, rheumatoid arthritis, breast cancer in hormonal therapy, in order to investigate differences in PROMs outcomes between PLWH and other pathologies. METHODS: A cross-sectional observational study was performed by using questionnaires investigating health-related quality of life (Medical Outcomes Study Short Form 36-item Health Survey), work productivity (WPI), and global health status (EQ-5D-3L). They were administered to patients affected by chronic diseases consecutively observed at a single University Hospital during a 10 months period, with comparable disease related aspects. Logistic regression analysis was used to analyze the association between disease group (HIV vs OC) and PROMs. RESULTS: 230 patients were enrolled (89 PLWH, 143 OC). Mean age: 49 years (SD 10), mean time of disease 12 years (10), 96% were Caucasian, 35% assumed polypharmacy, 42% of male were PLWH versus 16% OC (p < 0.001), 19% PLWH versus 6% OC had clinical complications (p < 0.001). HIV infection was independently associated to a better health-related quality of life in several domains compared with the other conditions, except in mental health, whereas a worst health-related quality of life in most domains was reported by older patients and those experiencing polypharmacy. CONCLUSIONS: In this cohort of patients with chronic conditions followed within the same health setting, PLWH showed better self-reported health outcomes compared to other chronic conditions with comparable characteristics of chronicity. The potential detrimental role of older age and polypharmacy in most outcomes suggests the need of longitudinal assessment of PROMs in clinical practice.

Process mining to optimize palliative patient flow in a high-volume radiotherapy department.

INTRODUCTION: In radiotherapy, palliative patients are often suboptimal managed and patients experience long waiting times. Event-logs (recorded local files) of palliative patients, could provide a continuative decision-making system by means of shared guidelines to improve patient flow. Based on an event-log analysis, we aimed to accurately understand how to successively optimize patient flow in palliative care. METHODS: A process mining methodology was applied on palliative patient flow in a high-volume radiotherapy department. Five hundred palliative radiation treatment plans of patients with bone and brain metastases were included in the study, corresponding to 290 patients treated in our department in 2018. Event-logs and the relative attributes were extracted and organized. A process discovery algorithm was applied to describe the real process model, which produced the event-log. Finally, conformance checking was performed to analyze how the acquired event-log database works in a predefined theoretical process model. RESULTS: Based on the process discovery algorithm, 53 (10%) plans had a dose prescription of 8 Gy, 249 (49.8%) plans had a dose prescription of 20 Gy and 159 (31.8%) plans had a dose prescription of 30 Gy. The remaining 39 (7.8%) plans had different dose prescriptions. Considering a median value, conformance checking demonstrated that event-logs work in the theoretical model. CONCLUSIONS: The obtained results partially validate and support the palliative patient care guideline implemented in our department. Process mining can be used to provide new insights, which facilitate the improvement of existing palliative patient care flows.

IMproved MAnagement (IM-MA study) in cancer-related pain: the value of a joint approach by an integrated team of radiotherapist and anesthetist.

PURPOSE: Purpose of this study was to retrospectively review our experience of multidisciplinary clinic providing a joint approach by radiation oncologist and anesthetist for patients with cancer pain to evaluate the adequacy and the IMprovement in MAnagement (IM-MA study) of this symptom. METHODS: A Team for Pain Management (TPM) represented by radiation oncologist and anesthetist weekly provided consultations to patient presenting cancer pain. TPM prospectively reported epidemiologic, symptomatic, and pharmacological data. TPM modified pain therapy and indicated antalgic radiotherapy. Patients were evaluated at baseline and after 4 weeks after intervention. RESULTS: From November 2015 to April 2016, 65 patients were evaluated by TPM. At the baseline, 18 patients (27.7%) were undertreated (i.e., receiving inadequate pain management); furthermore, 27 patients (41.5%) despite receiving strong opioids had uncontrolled pain. After 4 weeks from intervention, undertreated patients were reduced to 1.53%. For those patients undergone to radiotherapy, response at 34 weeks was scored as follows: complete response 28.8%, partial response 46.7%, pain progression 0.95%, indeterminate response 23.8%. CONCLUSIONS: A multidisciplinary Team for Pain Management improved the clinical management, optimizing pain control and increasing adequacy of pharmacological management. The TPM intervention seems particularly worth for patients presenting specific features including BTcP, neuropathic pain, severe pain due to bone metastases, and any potential candidate to radiotherapy. Larger series and QoL questionnaires are required to confirm these results.

Diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) values for detection of malignant vertebral bone marrow lesions.

Malignant spinal bone marrow disorders are one of the major causes of significant morbidity and reduction in quality of life in oncological patients. Thus, the characterization of these conditions is of crucial importance in the management of these patients. Magnetic resonance (MR) imaging plays a vital role in differentiation between benign and malignant spinal bone marrow disorders. However, morphological imaging features, based on T1 and T2 relaxation properties, might fail in differentiating between these conditions because signal characteristics may overlap. Quantitative MR imaging based on diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) values has been proved to help in defining the nature of the lesion. The aims of this paper were: to review basic principles of DWI technique and ADC maps, to describe DWI and ADC maps appearances of normal vertebral bone marrow briefly, to discuss the DWI and ADC maps characteristics in vertebral malignant lesions, to provide indications for differential diagnosis between malignant and benign lesions.

Squamous cell carcinoma of the rectum: The treatment paradigm.

PURPOSE: This study was planned to clarify the optimal treatment for squamous cell carcinoma of the rectum, an histological entity extremely rare. METHODS: Ten patients with histologically proven squamous cell carcinoma of the rectum were treated with concomitant radiochemotherapy. Radiation therapy was delivered with a 3Dconformational multiple field technique to a dose ranging from 45 to 76.5 Gy, with 6-15 MV energy photons. Chemotherapy consisted of an antimetabolite drug in association with mitomycin C or oxaliplatin. Overall survival and disease free survival were considered in months from the end of the concomitant treatment. RESULTS: All patients completed programmed radiochemotherapy treatment but two patients were excluded to the analysis. Six patients (75%) presented negative biopsy 6 months after the end of radiochemotherapy. Seven patients (87.5%) showed a tumour regression after initial treatment. Only 1 patient underwent salvage surgery. Considering a mean follow-up of 41.75 months, 7 patients are still disease free survivors. Only 1 patient developed local recurrence at 6 months and he died 14 months after abdomino-perineal resection. CONCLUSION: Primary radio chemotherapy, with a curative intent, could be considered the treatment modality of choice for squamous carcinoma of the rectum.

The role of radiotherapy in adult medulloblastoma: long-term single-institution experience and a review of the literature.

Medulloblastoma (MB) occurs infrequently in adult patients and standard treatment is still controversial. We report our long-term, single-institution experience of adult MB and a review of the literature. We analysed adult patients with histologically proved MB treated by postoperative radiotherapy. Primary endpoints were local control (LC), disease-free survival (DFS), and overall survival (OS). Acute toxicity was reported according to CTC-NCI score vers. 3.0 and specific neuropsychological assessment analysis was performed to define late brain toxicity. From 1990-2008, 13 patients were treated by craniospinal (CSI, 12/13) or cranial irradiation (1/13, because of bad clinical conditions). Median follow up was 101 months (64-218). Complete radiological response was observed in 12/13 patients and a partial response in 1/13. Ten-year LC, OS, and DFS were 91, 76, and 84%, respectively. Two patients died because of local and spinal progression after 13 and 62 months. Acute G3 haematological toxicity (RTOG score) was observed for one patient only. The neuropsychological analysis did not reveal late toxicity related to brain radiotherapy. This experience confirms the efficacy and safety of radiotherapy in adult MB patients, resulting in very interesting 10-year LC and OS.

Laparoscopic resection with intraoperative radiotherapy: a new step in the multimodal treatment of advanced colorectal cancer.

BACKGROUND: Local recurrence is one of the most important problems related to resection of rectal cancer in locally advanced cases (T3-T4). Total mesorectal excision (TME) is the mainstay of surgical therapy, although many articles have been published about the availability of intraoperative radiotherapy (IORT) for the control of locally advanced rectal cancers. METHODS: The authors describe six patients affected by advanced rectal cancer (T3N1) whom they treated with neoadjuvant radiochemotherapy and laparoscopic rectal resection combined with TME and IORT. RESULTS: The operative time did not exceed 6 h in any case with IORT treatment. The procedure itself and the transfer of patients to the radiotherapy room accounted for about 2 h. The postoperative course was uneventful in every case, and all the patients were discharged within the first 8 postoperative days. CONCLUSIONS: This report describes the technical aspect and the feasibility of IORT associated with laparoscopic surgical resection for rectal cancer.

Locoregional pain treatment. Troubles and prospectives: antalgic radiotherapy.

Pain control in patients with cancer represents a significant aspect of radiation therapy practice. Radiation therapy is one of the most effective, and often the only, therapeutic option to relieve pain caused by nerve compression or infiltration by malignant tumor, pain from liver and bony metastases and it provides also successful palliation of dysphagia caused by oesophageal carcinoma and of pain due to pancreatic cancer. Various instruments are avaliable for pain evaluation but a valid methodology to assess the pain status in the patient with cronic cancer pain is still an important clinical problem. In this complex and wide scene this contribution wants to confirm the role of radiotherapy in cancer pain control, in paricular in bone metastases, and to involve the patient himself in the survey of radiation treatement response by a subjective evaluation of bone pain, elaborating a reliable and valid unidimensional method by which recording the self-rating of the patient's sensation. Materials and Methods For the subjective evaluation of pain caused by bone metastases we used an application form with which drawing information in the course of time in terms of: response to the treatment, duration of symptom relief and quality of life. Results Considering as cut-off a dose of 30 Gy, which is commonly considered the conventional treatment for bone metastases, the partial and complete response were, respectively, of 54% and 30% in the patients treated with dose higher than or equal to 30 Gy, and 60% and 20% in the ones treated with doses lower than 30 Gy. In the whole, in 84 patients, the global response was of 82%, in accordance with literature. Conclusion In this retrospective study, the analysis of patient's subjective experience confirmed the effectiveness of radiotherapy in reducing pain caused by bone metastases and in improving quality of life of the patient himself. Given the conflicting opinions on low-dose short-course radiotherapy versus prolonged or higher dose schedules on initial pain relief, we are going to define categories of homogenous patients on whom starting treatment schedules with the aim or of palliation of the symptom or of the functional restitutio, on the base of the expectation and the quality of life.

Advances in the treatment of lung cancer: economic and organizational aspects.

The organizational optimization in radiotherapy tends to a correct balance of quality of service and containment of health care expenditure; this goal is necessarily correlated with the real potentialities available to each center while considering the possible clinical benefits for the patient. In lung cancer, outcomes achieved with radiation therapy are encouraging in terms of local control and survival when treatment is performed with the available modern technology whose costs from an exclusively economic analysis are shown to be still quite high. In an assessment focused on clinical outcomes, better local control, higher survival and improved quality of life represent tangible benefits: this has a positive impact on community costs and may represent a high priority goal for health care providers, yielding a benefit that can be quantified with the most recent analyses of health care economy.

Cancer of the anal canal and local control.

Concomitant radiochemotherapy is the standard treatment of squamous cell carcinoma of the anal canal. It can afford a high local control rate though the same impact has not been observed on survival. A few reports have concerned the impact of local control on distant metastases and survival. From 1988 to 1998 at the "Divisione di Radioterapia" of the "Università Cattolica del S. Cuore" of Rome 30 patients with squamous cell carcinoma of the anal canal were treated for cure. Treatment consisted of two cycles of radiotherapy (23.4 Gy) with a 4-5 week split in each cycle. 5FU (100 mg/sqm/24 h) was administered in continuous infusion for the first 4 days of therapy; mitomycin C (10 mg/sqm bolus) was administered on day 1, 4-6 weeks after the end of cycle 2 of concomitant radiochemotherapy, patients received a boost of interstitial brachytherapy. Local control on T of all patients was 84% at 5 years. Six patients showed locoregional recurrence: 3 recurrences on T and 4 disease progressions in locoregional lymph nodes. 3 of 6 patients underwent salvage surgery. The initial extent of the disease, the patient's age and brachytherapy boost did not have a statistically significant influence on local control. Two of the 30 patients showed liver metastases, and at their appearance, one patient was free of local disease while the other showed locoregional progression after Miles' operation for salvage. The metastasis-free interval was not significantly influenced by local control, although at 5 years, 96% of patients with local control of T were free of metastases vs 75% of those with recurrence on T (p = 0.22). Overall actuarial survival at 5 years was 75%. The behavior of survival in our experience seemed to be significantly influenced by local control: in the group with local control, 5-year survival was 85% vs 40% of patients with local recurrence (p = 0.01).
