The clinical features, management and outcomes of lymphoma in pregnancy: A multicentre study by the Australasian Lymphoma Alliance.

Lymphoma in pregnancy (LIP) presents unique clinical, social and ethical challenges; however, the evidence regarding this clinical scenario is limited. We conducted a multicentre retrospective observational study reporting on the features, management, and outcomes of LIP in patients diagnosed between January 2009 and December 2020 at 16 sites in Australia and New Zealand for the first time. We included diagnoses occurring either during pregnancy or within the first 12 months following delivery. A total of 73 patients were included, 41 diagnosed antenatally (AN cohort) and 32 postnatally (PN cohort). The most common diagnoses were Hodgkin lymphoma (HL; 40 patients), diffuse large B-cell lymphoma (DLBCL; 11) and primary mediastinal B-cell lymphoma (PMBCL; six). At a median follow up of 2.37 years, the 2- and 5-year overall survival (OS) for patients with HL were 91% and 82%. For the combined DLBCL and PMBCL group, the 2-year OS was 92%. Standard curative chemotherapy regimens were successfully delivered to 64% of women in the AN cohort; however, counselling regarding future fertility and termination of pregnancy were suboptimal, and a standardised approach to staging lacking. Neonatal outcomes were generally favourable. We present a large multicentre cohort of LIP reflecting contemporary practice and identify areas in need of ongoing research.

Capturing the lived experiences of women with lymphoma in pregnancy: a qualitative study.

Lymphoma in pregnancy is a rare and challenging diagnosis that complicates ∼1:6000 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).

Haemoglobin and Hematinic Status Before and After Bariatric Surgery over 4 years of Follow-Up.

PURPOSE: Bariatric surgery is associated with deficiencies of vitamins and minerals, and patients are routinely advised supplements postoperatively. We studied prevalence of vitamin B12, folate and iron deficiencies and anaemia before and after bariatric surgery over 4 years of follow-up. MATERIALS AND METHODS: We performed a retrospective cohort analysis of 353 people with obesity, including 257 (72.8%) women, who underwent gastric bypass (252, 71.4%) or sleeve gastrectomy (101, 28.6%) at our National Health Service bariatric centre in Northwest England. RESULTS: At baseline, mean (standard error) age was 46.0 (0.6) years, body mass index 53.1 (0.4) kg/m2, serum vitamin B12 400.2 (16.4) pg/L, folate 7.7 (0.2) µg/L, iron 12.0 (0.3) µmol/L, ferritin 118.3 (8.4) µg/L and haemoglobin 137.9 (0.8) g/L. Frequency of low vitamin B12 levels reduced from 7.5% preoperatively to 2.3% at 48 months (P < 0.038). Mean folate levels increased from baseline to 48 months by 5.3 µg/L (P < 0.001) but frequency of low folate levels increased from 4.7% preoperatively to 10.3% (P < 0.048). Ferritin levels increased from baseline to 48 months by 51.3 µg/L (P < 0.009). Frequency of low ferritin levels was greater in women (39.1%) than in men (8.9%) at baseline (P < 0.001) and throughout the study period. Haemoglobin was low in 4.6% of all patients at baseline with no significant change over the study period. CONCLUSION: There were notable rates of haematinic insufficiencies in bariatric surgical candidates preoperatively. Our study lends further support to regular supplementation with vitamin B12, folic acid, and iron in people undergoing bariatric surgery.

Vitamin B12 deficiency - A 21st century perspective .

Vitamin B12 deficiency is a common condition which can present with non-specific clinical features, and in severe cases with neurological or haematological abnormalities. Although classically caused by pernicious anaemia, this condition now accounts for a minority of cases and vitamin B12 deficiency occurs most often due to food-bound cobalamin malabsorption. Since missing the diagnosis can result in potentially severe complications, including degeneration of the spinal cord and pancytopaenia, vitamin B12 deficiency must be diagnosed early and managed appropriately. Intramuscular injections have been the mainstay of treatment, but oral replacement therapy can be effective in many cases. There is accumulating evidence that high vitamin B12 levels (values varied from 350-1,200 pmol/l) are associated with haematological and hepatic disorders, in particular with malignancy. This review focuses on the developments in the clinical features and management of vitamin B12 deficiency over the last decade.
