RESUMO
Traditionally, Sezary syndrome (SS) has been associated with few therapeutic options and poor prognosis, with 5-year disease-specific survival (DSS) less than one-third in historical cohorts. However, newer therapies and combinations are associated with impressive time-to-next-treatment (TTNT), particularly allogeneic stem-cell transplantation (AlloSCT) and combination therapies notably those including extracorporeal photopheresis. In this multicentre, international study, we explored the prognostic outcomes of 178 patients exclusively managed for SS, diagnosed between 2012 and 2020, and treated in the modern therapeutic era. In this cohort, 58 different therapies were delivered, with 13.5% of patients receiving AlloSCT. Long-term survival exceeded historical reports with 5-year DSS and OS of 56.4% and 53.4% respectively. In those receiving AlloSCT, prognosis was excellent: 5-year DSS and OS were 90.5% and 78.0% respectively. Confirming the results from the Cutaneous Lymphoma International Consortium (CLIC), LDH and LCT had significant prognostic impact. Unlike earlier studies, stage did not have prognostic impact; we speculate that greater relative benefit favours patients with extensive lymphomatous nodal disease (Stage IVA2) compared to historical reports. For patients ineligible for AlloSCT, the prognosis remains relatively poor (5-year DSS 51.4% and OS 49.6%), representing ongoing unmet needs for more effective novel agents and investigation of improved therapeutic combinations.
RESUMO
Follicular lymphoma (FL) is the most common indolent non-Hodgkin lymphoma subtype, accounting for 15-20% of all lymphoma diagnoses. Although typically slow-growing and responsive to frontline therapies, advanced-stage FL remains incurable with current treatments and typically follows a chronic relapsing/remitting course with increasingly shorter responses to subsequent lines of therapy. Outcomes are highly variable; some patients experience prolonged first remissions that may approximate a 'functional cure'. By contrast, a significant minority of patients experience disease progression shortly after frontline treatment resulting in high rates of lymphoma-related mortality. Reflecting on the heterogeneous natural history of FL, clinical practice varies widely, particularly in controversial areas, including appropriate disease staging, selection of management strategies and duration of clinical follow-up. This position statement presents an evidence-based synthesis of the literature for application in Australasian practice.
RESUMO
Positron emission tomography (PET) response assessment using the Deauville score has prognostic utility in relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) undergoing autologous stem-cell transplantation (ASCT). Improved predictive methods are required to identify patients with poor outcomes who may be better considered for other salvage options. We investigated the prognostic value of mean tumour volume (MTV) and maximum standardised uptake value (SUVmax) at pre-salvage and pre-ASCT time-points, and the quantitative changes between scans (∆MTV and ∆SUVmax). One hundred and twenty-five patients with R/R DLBCL underwent salvage immunochemotherapy and ASCT: 80 patients had pre-salvage PET and 90 had pre-ASCT PET available. With a median follow-up of 5.6 years, 5-year progression-free survival (PFS) and overall survival (OS) were 52% and 65%, respectively. For patients with PET-positive residual disease after salvage therapy, pre-ASCT MTV was a significant negative prognosticator for PFS (HR 1.19 per 100 ml, p < 0.001) and OS (HR 1.78 per 100 ml, p < 0.001). Similarly, pre-ASCT SUVmax was negatively associated with PFS (HR 1.08, p < 0.001) and OS (HR 1.08, p < 0.001). Notably, pre-salvage MTV and SUVmax and ∆MTV and ∆SUVmax were not associated with PFS or OS. In conclusion, pre-ASCT MTV and SUVmax appear to be of greater predictive value than the degree of response. Potential application may exist for PET-directed management of R/R DLBCL patients.

The CD30-postive lymphoproliferative disorders, including lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma, account for up to 30% of all cutaneous T-cell lymphomas (CTCLs) and are the second most common form of CTCLs after mycosis fungoides. Both conditions differ in their clinical presentations; however, they share the expression of the CD30 antigen as a common immunophenotypic hallmark. There is a wide spectrum of management options depending on factors such as extent of disease, staging and treatment tolerability. This Clinical Practice Statement is reflective of the current clinical practice in Australia.

Peripheral T-cell lymphomas (PTCL) represent a heterogeneous disease group accounting for 10% of non-Hodgkin lymphomas. PTCL patients have typically poorer outcomes compared with aggressive B-cell lymphomas. However, such outcomes are heavily dependent on subtype. Although anthracycline-based regimens such as cyclophosphamide, doxorubicin, vincristine and prednisone remain the standard first-line treatment for most aggressive PTCL, there are important variations including incorporation of novel agents, use of radiotherapy and judicious consideration of stem cell transplantation. Relapsed or refractory disease represents a significant area of unmet need where chemotherapy intensification has limited efficacy and novel agents such as brentuximab vedotin and pralatrexate provide additional opportunities for attainment of remission and potential stem cell transplant. In the future, pre-therapy prognostic biomarkers including genomic characterisation, may aid in risk stratification and help guide initial patient management to improve survival. There is an urgent need to understand better the pathogenesis of PTCL to facilitate novel drug combinatorial approaches to improve survival. This position statement represents an evidence-based synthesis of the literature for application in Australian and New Zealand practice.

Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma subtype, accounting for 30-40% of lymphoma diagnoses. Although aggressive, cure is achievable in approximately 60% of cases with primary chemoimmunotherapy, and in a further substantial minority by salvage therapy and autologous stem cell transplantation. Despite promising activity in early phase clinical trials, no intensified or novel treatment regimen has improved outcomes over R-CHOP21 in randomised studies. However, there remain several areas of controversy including the most appropriate prognostic markers, central nervous system prophylaxis and the optimal treatment for patients with high-risk disease. This position statement presents an evidence-based synthesis of the literature for application in Australasian practice.

Extracorporeal photopheresis (ECP) has demonstrated therapeutic benefit in patients with Sézary syndrome (SS) and erythrodermic mycosis fungoides (e-MF). To examine the efficacy of ECP in the modern era of novel therapies, we conducted a retrospective analysis of 65 patients with a diagnosis of SS or e-MF with blood involvement who were treated with ECP at our institute. Overall survival (OS), time to next treatment (TTNT), and skin response rate (RR) were used as the study end points to determine patient outcome. The median follow-up from diagnosis was 48 months (range 1-225 months), with a median predicted OS of 120 months. The majority (88%) of patients commenced ECP at treatment lines 1 to 3, either as a monotherapy or in conjunction with other systemic agents. The use of ECP monotherapy resulted in a significantly longer median TTNT when compared with interferon-α (P = .0067), histone deacetylase inhibitors (P = .0003), novel immunotherapy agents (P = .028), low-dose methotrexate (P < .0001), and chemotherapy (P < .0001). In particular, early commencement of ECP at treatment lines 1 to 3 yielded a TTNT of 47 months. The results of our study support the utilization of ECP for SS/e-MF, and we recommend that ECP should be considered as early as possible in the treatment paradigm for these patients.

The management of Hodgkin lymphoma (HL) has undergone significant changes in recent years. Due to the predilection of HL to affect younger patients, balancing cure and treatment-related morbidity is a constant source of concern for physicians and patients alike. Positron emission tomography adapted therapy has been developed for both early and advanced stage HL to try and improve the outcome of treatment, while minimising toxicities. The aim of this review is to digest the plethora of studies recently conducted and provide some clear, evidence-based practice statements to simplify the management of HL.

The COVID-19 pandemic poses a unique challenge to the care of patients with haematological malignancies. Viral pneumonia is known to cause disproportionately severe disease in patients with cancer, and patients with lymphoma, myeloma and chronic lymphocytic leukaemia are likely to be at particular risk of severe disease related to COVID-19. This statement has been developed by consensus among authors from Australia and New Zealand. We aim to provide supportive guidance to clinicians making individual patient decisions during the COVID-19 pandemic, in particular during periods that access to healthcare resources may be limited. General recommendations include those to minimise patient exposure to COVID-19, including the use of telehealth, avoidance of non-essential visits and minimisation of time spent by patients in infusion suites and other clinical areas. This statement also provides recommendations where appropriate in assessing indications for therapy, reducing therapy-associated immunosuppression and reducing healthcare utilisation in patients with specific haematological malignancies during the COVID-19 pandemic. Specific decisions regarding therapy of haematological malignancies will need to be individualised, based on disease risk, risks of immunosuppression, rates of community transmission of COVID-19 and available local healthcare resources.

Primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT) is one of the well-recognized extranodal lymphomas commonly addicted to the B-cell receptor-MYD88 superpathway. We aimed to describe the genomic changes in a patient who progressed through treatment with ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor. An 80-year-old woman presented with multiply relapsed PCDLBCL-LT after multiple lines of chemoimmunotherapy and radiotherapy. Pre-treatment testing of the localized cutaneous tumor lesion on a lymphoid amplicon panel demonstrated an MYD88 p.L265P mutation. Ibrutinib therapy was subsequently commenced, resulting in complete resolution of the skin disease. Despite an ongoing skin response, the patient developed progressive nodal disease at two months. Genomic analysis of the cutaneous tumor sample at baseline was compared to that of the inguinal lymph node upon progression, and revealed the acquisition of multiple genomic changes. These included several aberrations expected to bypass BTK inhibition, including two CARD11-activating mutations, and a deleterious mutation in the nuclear factor kappa B (NF-κB) negative regulator, NFKBIE. In addition, an IgH-IRF8 translocation was detected (which brings the IRF8 transcription factor under control of the immunoglobulin heavy chain locus), representing a third plausible mechanism contributing to ibrutinib resistance. Several copy-number changes occurred in both samples, including an amplification of 18q, which encodes the anti-apoptotic protein BCL2. We describe the first case of novel genomic changes of PCDLBCL-LT that occurred while on ibrutinib, providing important mechanistic insights into both pathogenesis and drug resistance.

Malnutrition is prevalent in patients undergoing (chemo)radiotherapy (RT) for lung cancer. This pilot study tested the feasibility and acceptability of delivering an intensive nutrition intervention for lung cancer patients receiving RT. Twenty-four patients with lung cancer were randomized to receive the intervention which employed a care pathway to guide intensive dietary counseling from pretreatment until 6-wk posttreatment or usual care. Nutritional, fatigue, and functional outcomes were assessed using valid and reliable questionnaires before randomization, at the start and end of RT and 1- and 3-mo post-RT. Consent rate was 57% with an overall attrition of 37%. Subject compliance with the completion of study questionnaires was 100%. A clinically important mean difference indicated greater overall satisfaction with nutritional care in the intervention group (5.00, interquartile range [IQR] 4.50-5.00; 4.00, IQR 4.00-4.00). Clinically important differences favoring the intervention were observed for weight (3.0 kg; 95% confidence interval [CI] -0.8, 6.8), fat-free mass (0.6 kg; 95% CI -2.1, 3.3), physical well-being (2.1; 95% CI -2.3, 6.5), and functional well-being (5.1; 95% CI 1.6, 8.6), but all 95% CIs were wide and most included zero. Recruitment feasibility and acceptability of the intervention were demonstrated, which suggest larger trials using an intensive nutrition intervention would be achievable.

Clinical guidelines widely recognize the importance of multidisciplinary meetings (MDM) in the optimal care of lung cancer patients. The published literature suggest that dedicated Lung Cancer MDM lead to increased treatment utilization rates and improved survival outcomes for patients with lung cancer. For radiation oncologists, Lung Cancer MDM have been proven to support evidence-based practice and improve the utilization of radiotherapy. Lung Cancer MDM also allow for education and promotion of specialty radiotherapy services. The fast pace of modern medicine is also presenting new challenges for the multidisciplinary lung cancer team, and technological advances are likely to lead to new changes in the structure of traditional Lung Cancer MDM.

INTRODUCTION: Total body irradiation (TBI) practices vary considerably amongst centres, and the risk of treatment related toxicities remains unclear. We report lung doses for 142 TBI patients who underwent either standing TBI with lung shield blocks or lying TBI without blocks. METHODS: Lung doses were calculated for 142 TBI patients treated between June 2016 and June 2021. Patients were planned using Eclipse (Varian Medical Systems) using AAA_15.6.06 for photon dose calculations and EMC_15.6.06 for electron chest wall boost fields. Mean and maximum lung doses were calculated. RESULTS: Thirty-seven patients (26.2%) were treated standing using lung shielding blocks with 104 (73.8%) treated lying down. Lowest relative mean lung doses were achieved using lung shielding blocks in standing TBI, reducing the mean lung doses to 75.2% of prescription (9.9 Gy), ±4.1% (range 68.6-84.1%) for a prescribed dose of 13.2 Gy in 11 fractions, including contributions from electron chest wall boost fields, compared to 12 Gy in 6 fraction lying TBI receiving 101.6% mean lung dose (12.2 Gy) ±2.4% (range 95.2-109.5%) (P ⪠0.05). Patients treated lying down with 2 Gy single fraction received the highest relative mean lung dose on average, with 108.4% (2.2 Gy) ±2.6% of prescription (range 103.2-114.4%). CONCLUSION: Lung doses have been reported for 142 TBI patients using the lying and standing techniques described herein. Lung shielding blocks significantly reduced mean lung doses despite the addition of electron boost fields to the chest wall.

BACKGROUND AND PURPOSE: Primary cutaneous CD4 + small/medium T-cell lymphoproliferative disorder (PCSMLPD) is a benign behaving condition, typically manifesting as solitary head or neck papules, frequently creating cosmetic concerns. Optimal management of this rare disease is unclear. Herein, patterns of care and treatment outcomes are described, with particular focus on low-dose RT. MATERIALS AND METHODS: Eligibility required biopsy-proven PCSMLPD on central review, diagnosed between 2007-2022. Patterns of care, treatment responses and relapse patterns were assessed. Freedom-from-progression (FFP) was compared between RT and surgery. RESULTS: 41 patients were eligible. First-line treatments were: RT, 19 (46.3 %); surgery, 17 (41.5 %) (3 received adjuvant RT); watchful waiting, 5 (12.2 %). Median follow-up was 37.7 months. Overall, 24 patients received RT (19 definitive first-line, 3 adjuvant, 2 second-line). 10 (42 %) received 4 Gy in 2 fractions (with no acute toxicities); 14 (58 %) received 20-40 Gy. Complete response rate was 100 %. No post-RT relapses observed. After first-line surgery alone (n = 14, 3 with positive margins), 4 (28.5 %) experienced relapse (2 local, 2 distant). Watchful-waiting (n = 5) led to partial resolution post-biopsy in 4 patients; no complete resolution seen. 3-year FFP for RT alone was 100 % vs 61 % for surgery alone (p = 0.12). CONCLUSION: RT is a successful, non-invasive option for PCSMLPD: 100 % achieved complete response, with no relapses, and FFP appearing numerically superior to surgery in this cohort. In this first series of low-dose RT for PCSMLPD, 4 Gy in 2 fractions appears an excellent treatment option, offering durable disease control, no acute toxicities and convenient treatment time of only 2 days.

PURPOSE: Radiation-induced meningiomas (RIM) are the most common secondary neoplasm post cranial radiotherapy, yet optimal surveillance and treatment strategies remain contentious. Herein, we report the clinical outcomes and radiological growth rate of RIM, diagnosed in a cohort of survivors undergoing MRI screening, with the objective of informing clinical guidelines and practice. MATERIALS AND METHODS: Long-term survivors of paediatric or young-adult malignancies, diagnosed with RIM between 1990 and 2015, were identified. Absolute (AGR) and relative (RGR) volumetric growth rates were calculated. Rapid growth was defined as AGR > 2 cm3/year or AGR > 1 cm3/year and RGR ≥ 30% RESULTS: Fifty-two patients (87 RIM) were included. Median age at first RIM diagnosis was 33.9 (range,13.8-54.1) years. Seventy-seven (88%) RIM were asymptomatic at detection. Median follow-up time from first RIM detection was 11 (range, 0.6-28) years. Median absolute and relative volumetric growth rates were 0.05 (IQR 0.01-0.11) cm3 and 26 (IQR 7-79) % per year, respectively. Two (3.3%) RIM demonstrated rapid growth. Active surveillance was adopted for 67 (77%) RIM in 40 patients. Neurological sequelae due to RIM progression were reported in 5% of patients on active surveillance. Surgery was performed for 33 RIM (30 patients): 18 (54.5%) at diagnosis and 15 (45.5%) after active surveillance. Histopathology was WHO Grade 1 (85.2%), 2 (11.1%), 3 (3.7%). Following resection, 10-year local recurrence rate was 12%. During follow-up, 19 (37%) survivors developed multiple RIM. CONCLUSIONS: Asymptomatic RIM are typically low-grade tumours which exhibit slow growth. Active surveillance appears to be a safe initial strategy for asymptomatic RIM, associated with a low rate of neurological morbidity.

Despite increasing availability of therapies, patients with Sezary syndrome (SS) commonly endure multi-line treatment journeys, mostly with partial responses of short duration. Measuring clinical benefit is challenging; time-to-next-treatment (TTNT) provides a robust, objective measurement of efficacy. This international observational study examines patterns of clinical care and therapeutic benefit as measured by TTNT. TTNT was calculated for monotherapies and combination therapies, with consideration to treatment line. 178 patients with SS (73% de novo, 27% secondary) were included, receiving 721 lines of systemic therapy, with median follow-up of 56.9 months. Across all lines, 58 different therapeutic regimens were prescribed (54 were systemic therapies) and classified into 17 treatment groups. The most common first-line treatments were extracorporeal photopheresis (ECP)-containing combination therapy (20%) and retinoid monotherapy (19%). Median TTNT for all first-line therapies was short (5.4 months). First-line, combination therapies had longer median TTNT than monotherapies, 10.0 vs 5.0 months (P = .004), respectively. Later delivery of combination therapies was associated with shorter clinical benefit, with median TTNT reduced to 6.2 and 2.2 months for mid-line (2nd-4th line) and late-line (≥5th line), respectively (P < .001). First-line ECP-containing treatments were associated with longer median TTNT than non-ECP-containing treatments, 9.0 vs 4.9 months (P = .007). For both ECP-monotherapy and ECP-containing combination therapy, significant reductions in TTNT were seen in later lines. These data suggest therapeutic benefit from first-line delivery of combination therapy for SS and favor early inclusion of ECP in the treatment algorithm for those who can access it.

Lymphoma in pregnancy is a rare and challenging diagnosis that complicates â¼1:6000 pregnancies; posing a series of unique therapeutic, social, and ethical challenges to the patient, her family, and the medical professionals involved. These difficulties are compounded by the paucity of real-world data on the management of LIP, and a lack of relevant support systems for women in this setting. We conducted a retrospective multicenter qualitative study, interviewing women aged ≥18 years of age diagnosed with Hodgkin (HL) or non-Hodgkin lymphoma (NHL) during pregnancy or within 12 months postpartum, between 1 January 2009 and 31 December 2020 from 13 Australasian sites. Semi-structured telephone interviews were conducted, recorded, and analyzed using QSR Int NVivo 12 Pro (March 2020, USA) to quantify salient themes. Of the 32 women interviewed, 20 (63%) were diagnosed during pregnancy (16, 34, and 13% in the 1st, 2nd, and 3rd trimesters, respectively), while 12 (37%) were diagnosed post-partum. Women recalled that their chief concerns at diagnosis were the welfare of their child (n = 13, 41%) and a fear of dying (n = 9, 28%). Perceived diagnostic delay attributed to pregnancy was reported by 41% of participants. Other key themes were communication, educational materials, psychosocial supports, and oncofertility issues. To our knowledge this is the first report capturing the lived experiences of survivors of lymphoma during pregnancy, affording a unique opportunity to consider the management, psychosocial supports, and delivery of care to meet the needs of these women.What is the NEW aspect of your work? To our knowledge, this is the first report capturing and analyzing the healthcare experiences of survivors of Lymphoma in Pregnancy (LIP).What is the CENTRAL finding of your work? Women valued clear and empathic communication, provision of tailored educational materials, access to psychosocial supports (particularly childcare and financial supports), and timely oncofertility management in their healthcare journey.What is (or could be) the SPECIFIC clinical relevance of your work? Women's personal accounts of positive and negative experiences of LIP care provide insights into their specific concerns and needs which can shape healthcare policy and development of a specific framework for managing and supporting patients with LIP (and other cancers).
