ABSTRACT
Introduction & Objectives: The incidence of prostate cancer, both in the world and in the Russian Federation, tends to increase. In the Republic of Bashkortostan in 2021, 699 patients with this diagnosis were registered. 19.6% of patients had stage IV disease at the time of diagnosis. 5818 patients were registered, of which 361 died within a year. The effectiveness of hormonal treatment of common prostate cancer has time limitations, after which there is a development of resistance to castration and progression of the disease. To date, drugs such as kabazitaxel, sipuleucel-T vaccine, abiraterone, enzalutamide and radium-223 have been approved for use in metastatic CRPC. The purpose of the work: analysis of the experience of systemic radiotherapyand Radium - 223 patients with mCRPC in the Republic of Bashkortostan in 2021. Material(s) and Method(s): Analysis of patients who received systemic radiotherapy Radium - 223 in the Republic of Bashkortostan according to medical documentation and research data. In 2021, Radiy-223 radiotherapy was performed on 7 patients diagnosed with mCRPC. Median age 63.14 years. All patients met the criteria for treatment, i.e. had castration-resistant prostate cancer with bone metastases, without visceral metastases. All patients had concomitant pathology from the cardiovascular system, respiratory tract, endocrine system. According to the previous surgical treatment, patients were distributed as follows: orchidectomy - 4, prostatectomy - 1 and 2 patients underwent tumor biopsy. By morphology: Glisson 6 - 2 patients, Glisson 7 - 1, Glisson 8 - 3, Glisson 10 - 1. 4 patients were referred to Xofigo for radiologically confirmed progression, 3 patients were progressingin height at PSA levels. Result(s): 1 patient previously received 1 line of systemic therapy, 5 patients received 2 lines, 1 patient received 3 lines of therapy. 6 patients received all 6 courses of radiotherapy, 1 patient did not complete treatment due to COVID 19. He is expected to complete therapy. All patients are currently alive with no signs of disease progression. Serious side effects were not registered. Conclusion(s): The "therapeutic window" for the prescription of radium-223 is the period before the appearance of visceral metastases and decline of the somatic status. To achieve the maximum benefit from the appointment of radium-223, it is necessary to conduct >=5 cycles of therapy, which is possible in 1-2 treatment lines. It is necessary to select patients carefully for radiotherapy - Radium 223.Copyright © 2022 European Association of Urology. Published by Elsevier B.V.
ABSTRACT
Melanoma of unknown primary (MUP) was originally defined in 1963 as melanoma in the subcutaneous tissue, lymph nodes or visceral organs without the presence of a cutaneous, ocular or mucosal primary. The incidence of MUP is reported to be between 1% and 8% of all melanomas. MUP can be divided into lymph node involvement only and organ metastases. The aetiology of MUP is elusive. Possibilities proffered include an unrecognized melanoma, a previously excised melanoma that was misdiagnosed as benign, a primary melanoma that has completely regressed or the de novo malignant transformation of an aberrant melanocyte within a lymph node. We report our experience in a single tertiary referral centre. A database of all melanomas diagnosed between January 2018 and December 2021 was analysed for MUP. The total number of melanomas diagnosed in that timeframe was 298. Six patients (three males, three females) were identified as having MUP, with an incidence of 2%. Median age was 63.3 years (range 45-84). One (17%) presented with primary dermal metastatic deposits, 67% (n = 4) presented with isolated lymph node metastases, 0% presented with visceral metastases and 17% (n = 1) presented with isolated brain metastases. All six patients were reviewed by dermatology and ophthalmology. Fifty per cent (n = 3) were reviewed by ENT. One (17%) was referred to gynaecology. No primary melanoma was identified in any of the patients. All patients underwent a positron emission tomography-computed tomography (CT) scan to investigate for further metastases, and all underwent dedicated brain imaging via CT and magnetic resonance imaging. All patients underwent surgical resection of their MUP, and all were reviewed by medical oncology, with 83% (n = 5) undergoing treatment with immunotherapy. There have been no associated deaths to date. In five patients (83%) the MUP was diagnosed in 2021, and one (17%) was diagnosed in 2018. Recent studies have shown the impact of the COVID- 19 pandemic on the presentation of cutaneous melanoma, including an increased Breslow thickness at the time of presentation vs. a similar period pre-COVID-19. Our data indicate an increased rate of MUP presenting after the onset of the COVID-19 pandemic;however, given the low number overall, no conclusions can be drawn. There is no current literature regarding the increased rate of MUP since the COVID-19 pandemic. Further studies are required to investigate this. Recommendations for the evaluation of those with MUP include a full skin examination by a dermatologist and ocular examination to exclude primary melanoma. Patients should undergo imaging of the brain, thorax, abdomen and pelvis to assess disease burden. Referral to otorhinolaryngology can be considered to assess for mucosal melanoma of the nasopharynx. Gynaecology referral should be considered for those with inguinal lymphadenopathy. MUP is rare. Guidelines for the investigation of MUP are currently lacking and are needed to ensure the delivery of consistent evidence-based care for patients.
ABSTRACT
Background: Supervised exercise programs (SEP) have demonstrated an improvement in quality of life (QoL), cardiovascular health, treatment tolerance and disease outcomes in early breast cancer patients. In metastatic breast cancer (MBC), previous data suggest SEP are safe but no impact on QoL and a low adherence to programs were shown. These studies included a heterogenous population in terms of type of treatments received, numbers of previous lines or comorbidities. From our perspective, MBC profile that could benefit most from SEP needs to be explored. Thus, we conducted a pilot study to assess adherence, safety and impact on QoL of a combined SEP and nutritional program (NP) in a selected population of MBC of patients treated with cyclin-dependent kinase 4/6 inhibitors (iCDK 4/6). Method(s): This is a prospective, single center, single arm pilot study. SEP consisted in a 12-week intervention with twice a week in-person resistance exercise session. Patients also completed weekly aerobic exercise goals in self-managed sessions monitored with activity trackers. SEP was conducted by registered Physical Activity and Sports Science instructors that followed American College of Sports Medicine guidelines. In addition, participants had an initial nutritional assessment and personalized counselling by a qualified nutritionist. Adherence to treatment, biological variables and QoL assessments (FACIT-Fatigue and QLQ-C30 questionnaires) were collected at baseline (B) and week-12 (w12). Primary endpoint was global adherence (>=70% of attended sessions relative to scheduled sessions). Secondary endpoints included safety, changes in biological variables and QoL. Paired samples t-tests (Wilcoxon) were used to assess biological changes and QoL. Result(s): Patients (n=26) were recruited from October 2020 to November 2021. Median age was 47,5 years (45-55);84,6% of patients were ECOG 0. 42,3% of patients were receiving Abemaciclib;34,6% Ribociclib and 23,1% Palbociclib in first (73,1%) or second (26,9%) line treatment. Patients had bone (69,2%);visceral metastasis (57,7%) or both (30,8%). 2 patients did not start the intervention and additional 7 patients discontinued the program prematurely, the majority of them due to COVID-related concerns. Considering all patients who at least attended one session, global adherence was 66% (39-77,5%) and 45,8% of patients achieved an adherence of >= 70%. Patients reported an improvement in QoL [B global QLQ-C30 66,6 (50-75), w12 75 (66,6-83,3);p 0,0121] and fatigue [B FACIT-Fatigue 37 (30-44), w12 42 (38-48);p 0,0017]. Sit-to-stand repetitions in 30-second period also improved [(B 15 (12-17), 19 (15-23);p 0,0002]. Same benefits were seen in patients with adherence >= 70%. No statistically significant changes were seen in body fat or muscular composition and handgrip scores. Importantly, no safety issues related to study intervention were reported. Conclusion(s): Even though the study was conducted during COVID-19 pandemic, global adherence was 66%. For the first time in MBC, SEP and NP combined program demonstrated to be safe and improved QoL in patients with first or second line MBC treated with iCDK4/6. Further research is needed to identify strategies that improve QoL in MBC.
ABSTRACT
Background: Patients with HR- advanced/metastatic breast cancer (a/mBC) with a low level of HER2 (immunohistochemistry [IHC] score 1+ or IHC 2+ and negative in situ hybridization [ISH]) have poor prognosis. Combining 1L chemotherapy with immune checkpoint inhibitors can modestly improve outcomes vs chemotherapy alone, but treatment benefit is largely seen in patients with PD-L1+ disease. BEGONIA (NCT03742102) is an ongoing 2-part, open-label platform study, evaluating safety and efficacy of D, an anti-PD-L1 antibody, combined with other novel therapies in 1L triple-negative a/mBC, including HR-, HER2-low disease. T-DXd is a trastuzumab-topoisomerase I inhibitor antibody-drug conjugate that improves survival in patients with previously treated HR-, HER2-low mBC (NCT03734029;Modi NEJM 2022). Here, we report updated results of the T-DXd + D combination from BEGONIA. Method(s): Patients with unresectable HR-, HER2-low (per local testing, IHC 2+/ISH-, IHC 1+/ISH-, or IHC 1+/ISH untested) a/mBC were enrolled in the T-DXd + D arm. Patients eligible for 1L treatment, regardless of PD-L1 status, received intravenous T-DXd 5.4 mg/kg + D 1120 mg every 3 weeks until progression or unacceptable toxicity. PD-L1, assessed using the VENTANA PD-L1 (SP263) Assay, was defined as high if >= 5% of the tumor area was populated by PDL1-expressing tumor or immune cells. Primary endpoints were safety and tolerability. Secondary endpoints included investigator-assessed objective response rate (ORR;RECIST v1.1);progressionfree survival [PFS];and response duration. Patients included in the efficacy analysis had >= 2 ontreatment disease assessments, progressed, died, or withdrew from the study. Result(s): As of April 8, 2022, 56 patients received T-DXd + D (34 ongoing) and 46 were included in the efficacy analysis. Median (range) follow-up was 10.1 (0-22) months. Median age was 53.5 years, 71% had received prior treatment for early stage BC, and 64% had visceral metastases at baseline. Confirmed ORR was 26/46 (57% 95% CI, 41-71) and unconfirmed ORR was 33/54 (61% 95% CI, 47-74);1/46 patients (2%) had complete and 25/46 (54%) had partial responses. Confirmed response occurred irrespective of PD-L1 expression (PD-L1 high ORR, 5/7 [71%];PD-L1 low, 13/21 [62%];PD-L1 missing, 8/18 [44%]). Median duration of response was not reached;however, 64% of patients remained in response at 12 month follow-up and 73% had an ongoing response at data cutoff. Median PFS was 12.6 months (95% CI, 8-not reached). Adverse events (AEs) were consistent with the agents' known safety, with treatment-related AEs occurring in 49 patients (88%), any Grade 3/4 AEs in 18 patients (32%), and any serious AEs in 10 patients (18%). The most common all-Grade AEs were nausea (41 [73%]), fatigue (26 [46%]), and vomiting (17 [30%]). Adjudicated treatment-related interstitial lung disease/pneumonitis occurred for 5 patients (9%), which were mostly Grade 1 or 2 and 1 case of Grade 5 associated with COVID pneumonia. Seven patients (13%) and 21 patients (38%) had T-DXd dose reduction and dose delay, respectively;22 (39%) had D dose delay. Seven patients (13%) discontinued treatment due to AEs. Conclusion(s): For patients with HR-, HER2-low a/mBC, T-DXd in combination with D in the 1L setting shows manageable safety and promising efficacy including durable responses and an encouraging PFS. Although subgroups were small, responses were observed irrespective of PD-L1 expression. Analysis of additional translational data is ongoing. Funding(s): AstraZeneca/Daiichi Sankyo.
