Nephrotic syndrome with Minimal Change Disease and Atopy in NorthAfrican adults.

INTRODUCTION: In adults, minimal change disease (MCD) accounts for 15 to 25% of nephrotic syndrome (NS). Numerous reports have suggested a link between NS and atopy. However, data on treatment and prognosis of NS associated with allergy are limited. AIM: To examine the presenting characteristics, treatments and outcomes of adults with allergic MCD in a North African center. METHODS: This was an observational study using retrospectively collected data. Patients were recruited from the Nephrology department of Sahloul Hospital (Sousse, Tunisia) from January 2006 to December 2020. Adults with a biopsy proved MCD, which was associated with atopy, were included. RESULTS: Fifteen patients (eight males, age mean±SD: 34±13 years) were included. High eosinophil and immunoglobulin E (IgE) levels were noted in three and twelve patients respectively. The IgE mean level at the initial presentation was 1431 IU/ml. Allergic skin tests were positive in nine patients. All patients were treated with corticosteroids, five had anti-histamine therapy and five had hyposensitization therapy, which was successful in two patients. Thirteen patients had relapsed during follow-up. Mean eosinophil level was significantly higher in patients with frequent relapses compared to those with infrequent relapses (5415/mm³ vs. 239.12/mm³, respectively, p=0.022). Two patients had progressed to chronic renal failure. CONCLUSION: It is important to search for atopic disorders in patients with MCD to better control this disease and use specific treatments. However, the efficacy of anti-allergic therapies has to be proven.

Effect of Serelys Homme on the Incidence and Severity of Vasomotor Symptoms and Quality-of-Life Impairments in Patients Receiving Hormone Therapy and Radiation for Localized Prostate Cancer: Results of the ESCULAPE Phase 2 Prospective Study.

Purpose: Androgen deprivation therapy (ADT) may cause vasomotor symptoms (VMS) including hot flushes and sweats, which affect quality of life (QoL). Serelys Homme is a nonhormonal and a natural origin product that could affect VMS in men undergoing ADT. We evaluated effectiveness and tolerance of Serelys Homme administration on VMS and QoL of patients undergoing combined ADT and radiation therapy for prostate cancer. Methods and Materials: Between April 2017 and July 2019, 103 patients were screened, and 53 patients refused to participate in the study. Serelys Homme therapy consisted of a daily administration of 2 tablets for 6 months. Patients were evaluated with 4 questionnaires including the adapted Modified Rankin Scale (adapted-MRS), European Quality of Life 5 Dimensions 3 Level Version (EQ 5D3L), Functional Assessment of Cancer Therapy-Prostate (FACT-P), and Hot Flash Related Daily Interference Scale (HFRDIS) at day 0, day 90 (D90), and day 180 (D180). Statistical evaluation was performed using the Wilcoxon rank sign test. A 2-sided P < .05 was considered statistically significant. Results: Among the 50 patients, 4 withdrew after inclusion. All patients (n = 46) received either postoperative or definitive radiation therapy combined with a short (n = 15) or long course (n = 31) of ADT. Serelys Homme administration significantly decreased the rate of patients who had ≥7 VMS and 3 to 6 VMS per day. The number of patients presenting with moderate or severe VMS was decreased at D90 (P = .005) and at D180 (P = .005). In addition, VMS duration was reduced at D90 (P = .002) and D180 (P < .001). Finally, at D90 and D180, 11.1% and 16.0% of patients, respectively, with initial severe or moderate VMS had a complete response without further symptoms. Among QoL parameters, fatigue decreased significantly. Effectiveness evaluated by doctors was rated as moderate or good to excellent VMS control in 20% and 60% of the patients, respectively. No side effects were recorded in the whole population. Conclusions: This study demonstrated effectiveness and excellent tolerance of Serelys Homme. We observed a significant reduction of the frequency, duration, and intensity of hot flushes and sweats induced by ADT. Serelys Homme increased QoL scores. These encouraging results open the prospect to further studies and Serelys Homme use in patients undergoing ADT for prostate cancer.

Radiation Therapy Delivery Challenges in Older Patients During Coronavirus Disease 2019 Pandemic.

PURPOSE: The management of older patients in radiation therapy (RT) departments has been challenging in the context of the Coronavirus Disease 2019 (COVID-19) outbreak. We report our experience of RT adapted schedules or strategy changes in older patients during the COVID-19 pandemic. METHODS AND MATERIALS: Patients aged ≥75 years were recruited during weekly chart rounds. All were potentially eligible for a specific intervention to reduce the frequency of patients' visits to the hospital. The effect of deferring radiation and hypofractionation of RT schedules was assessed in terms of the number of courses initially planned and replanned during the lockdown. RESULTS: Twenty patients were identified during the official lockdown in France (March 17 to May 11). Median age was 78 years (75-95 years). Most patients were male (n = 12, 60%) being treated in the postoperative setting (n = 17, 85%). RT was delayed in 11 cases (55%) with hormonal therapy prescribed in 10 cases (50%). Altered RT fractionation was proposed for 5 cases (25%); combinations of altered fractionation and deferral of radiation were applied in 3 cases (15%). The number of radiation courses initially planned and replanned according to the pandemic context: 563 and 197, respectively (-62%; P < .001). None presented recurrence when RT was initiated, and no patient developed symptomatic COVID-19 infection. CONCLUSIONS: In the context of the COVID-19 outbreak, individual risk-based radiation therapy seems to be safe. Systematic screening of patients for COVID-19 before starting radiation therapy is mandatory. In our department the oncogeriatrics expertise availability for daily practice was of great use during the pandemic. Other prospective studies are needed to validate such strategies in case of resurgence of similar outbreaks.

Radiation Therapy Department Reorganization during the Coronavirus Disease 2019 (COVID-19) Outbreak: Keys to Securing Staff and Patients During the First Weeks of the Crisis and Impact on Radiation Therapy Practice from a Single Institution Experience.

PURPOSE: During the first weeks of the coronavirus disease 2019 (COVID-19) outbreak in France, it was necessary to clearly define organizational priorities in the radiation therapy (RT) departments. In this report, we focus on the urgent measures taken to reduce risk for both our staff and patients by reducing the number of patients receiving treatment. METHODS AND MATERIALS: We reviewed the fractionation schemes for all patients in our department, including those receiving treatment and those soon to start treatment. Our goals were to (1) decrease the number of patients coming daily to the hospital for RT, (2) adapt our human resources to continue patients' care in the department, and (3) help to cover understaffed COVID-19 sectors of the hospital. RESULTS: We identified 50 patients who were receiving treatment (n = 6), were going to start radiation after CT scan simulation (n = 41), or for whom the CT scan was pending (n = 3). The majority were women (64%) treated for breast cancer (54%). RT was delayed for 22 (44%) patients. The majority were offered hormone therapy as "waiting therapy." Hypofractionation was considered in 21 (42%) patients mainly with breast cancer (18 of 21, 86%). The number of courses initially planned and replanned as a result of the COVID-19 outbreak during the period of March 15 to May 31, 2020, were 1383 and 683, respectively, which represented a reduction of 50% (including delayed sessions) that allowed our reorganization process. CONCLUSIONS: To conserve resources during the pandemic, we successfully reduced the number of patients receiving treatment in a proactive fashion and adapted our organization to minimize the risk of COVID-19 contamination. Departments across the world may benefit from this same approach.

Axillary nodal irradiation practice in the sentinel lymph node biopsy era: Comparison of the contemporary available 3D and IMRT techniques.

OBJECTIVE: Our study aimed to compare regional node coverage and doses to the organ at risk (OAR) using conventional technique (CT) vs "AMAROS" (AT) vs intensity-modulated radiation therapy (IMRT) techniques in patients receiving regional nodal irradiation (RNI) for breast cancer (BC). METHODS: We included 30 consecutive patients with BC who received RNI including axillary nodes. Two independent and blinded dosimetric RNI plans were generated for all patients. For target volume coverage, we analyzed the V95%, the D95%, the mean and the minimal dose within the nodal station. For hotspots within nodal target volume, we used the V105%, the V108% and the maximal doses. For OAR, lung V20, mean lung and heart doses, the maximal dose to the brachial plexus and the axillary-lateral thoracic vessel junction region were compared between the three techniques. RESULTS: Target volume coverage and hotspots: Mean V95% in stations I, II, III and IV were 35.8% and 75% respectively with CV, 22.59 and 59.9% respectively with AT technique and 45.58 and 99.6% respectively with IMRT with statistically significant differences (p < 0.001). Mean V105% (cc) in axillary and supraclavicular stations were 21.3 and 6.4 respectively with CV, 1.2 and 0.02 respectively with AT technique and 0.5 and 0.4 respectively with IMRT with statistically significant differences (p < 0.001)..OARs: The mean ipsilateral lung V20 was 16.9%, 16.4 and 13.3% with CT, AT and IMRT respectively. The mean heart dose (Gy) was 0.3, 0.2 and 0.2 with CT, AT and IMRT respectively. The maximal dose to the plexus brachial (Gy) was 50.3, 46.3 and 47.3 with CT, AT and IMRT respectively. The maximal dose to the axillary-lateral thoracic vessel junction (Gy) was 52.3, 47.3 and 47.6 with CT, AT and IMRT respectively. The differences were statistically significant for all OAR (p < 0.001). CONCLUSION: AT is a valuable technique for RNI including axilla in patients with limited sentinel lymph node biopsy involvement without additional axillary lymph node dissection since it decreases hotspots in the target volume and lowers the radiation exposure of the OAR. For more advanced tumors or patients who did not respond to primary systemic therapy, CT or IMRT should be considered because of their better coverage of the potentially residual nodal disease. IMRT combines several advantages of offering high conformal plans, limited hotspots and protection of main OAR. The clinical impact of these dosimetric differences need to be addressed. ADVANCES IN KNOWLEDGE: This study is to our knowledge the first to compare conventional three-dimensional and IMRT techniques for regional nodal irradiation for each nodal station in breast cancer in a context of increasing utilization of axillary irradiation.

Metastasis of colon adenocarcinoma to the mandible: A case report.

INTRODUCTION: Metastasis is the primary cause of death among patients with colon cancer. Metastatic tumors in the oral cavity originating from the colon are rare, and the number of relevant clinical studies is limited. CASE REPORT: We report a case of a 79 year old woman who developed a mandibular tumefaction. Biopsy was performed and made the diagnosis of metastasis from colon cancer. The patient received palliative radiotherapy for the mandibular mass lesion. CONCLUSION: Oral metastatic tumor from colorectal cancer is very uncommon and is often found with advanced recurrent cancer. Therapeutic management that includes palliative treatment is the usual therapeutic option.
