RESUMO
BACKGROUND: Patient-reportedoutcomes (PROs) that assess health-related quality of life (HRQoL) are increasingly important components of cancer care and research that are infrequently used in sub-Saharan Africa (SSA). METHODS: We administered the Chichewa Pediatric Patient-Reported Outcome Measurement Information System Pediatric (PROMIS)-25 at diagnosis, active treatment, and follow-up among pediatric lymphoma patients in Lilongwe, Malawi. Mean scores were calculated for the six PROMIS-25 HRQoL domains (Mobility, Anxiety, Depressive Symptoms, Fatigue, Peer Relationships, Pain Interference). Differences in HRQoL throughout treatment were compared using the minimally important difference (MID) and an ANOVA analysis. Kaplan-Meier survival estimates and Cox hazard ratios for mortality are reported. RESULTS: Seventy-five children completed PROMIS-25 surveys at diagnosis, 35 (47%) during active treatment, and 24 (32%) at follow-up. The majority of patients died (n = 37, 49%) or were lost to follow-up (n = 6, 8%). Most (n = 51, 68%) were male, median age was 10 (interquartile range [IQR] 8-12), 48/73 (66%) presented with advanced stage III/IV, 61 (81%) were diagnosed with Burkitt lymphoma and 14 (19%) Hodgkin lymphoma. At diagnosis, HRQoL was poor across all domains, except for Peer Relationships. Improvements in HRQoL during active treatment and follow-up exceeded the MID. On exploratory analysis, fair-poor PROMIS Mobility <40 and severe Pain Intensity = 10 at diagnosis were associated with increased mortality risk and worse survival, but were not statistically significant. CONCLUSIONS: Pediatric lymphoma patients in Malawi present with poor HRQoL that improves throughout treatment and survivorship. Baseline PROMIS scores may provide important prognostic information. PROs offer an opportunity to include patient voices and prioritize holistic patient-centered care in low-resource settings.

BACKGROUND: We aimed to evaluate the association between autoimmune disease (AID) and lymphoma incidence in the Korean population. We also aimed to compare the overall survival (OS) in patients with AID-associated lymphoma (AAL) with that in patients with lymphoma without AID. MATERIAL AND METHODS: We used National Sample Cohort 2002-2015 provided by National Health Insurance Service. Among 1,011,638 patients, 994,496 were recruited for the final cohort: 130,987 patients (13.2%) in the AID group and 863,509 (86.8%) in control. Lymphoma was diagnosed in 1162 patients and 322 patients with accompanying AID, irrespective of the time point of diagnosis, were defined as AAL. Of those, patients who experienced lymphoma development at least one year after AID diagnosis were defined as post-AID lymphoma (N = 155). RESULTS: The median follow-up duration was 13.7 years. AAL accounted for 0.03% of total and 27.7% of lymphoma cases. AID patients experienced more Epstein-Barr virus (0.02 vs. 0.01%, P = 0.027) or Helicobacter pylori infection (63.9 vs. 41.4%, P < 0.001) than the control group did. AID was associated with a 1.45-fold increased risk of lymphoma. The median time interval from AID to AAL was 10.9 months. The risk of lymphoma increased in the order of: psoriasis (adjusted odds ratio [AOR] 1.61), systemic lupus erythematosus (AOR 3.99), multiple sclerosis (AOR 4.52), and sarcoidosis (AOR 26.37). Sjogren syndrome was not related to lymphoma in this cohort. The 5-year OS in AAL was not different from that in lymphoma patients without AID (60.9 vs. 61.5%, P = 0.970). CONCLUSIONS: The association patterns in AAL in Korean population were different from those of Western countries. Further studies on lymphomatogenesis from distinct baseline characteristics (e.g. chronic infection status) would elucidate the difference based on race and ethnicity.

BACKGROUND: Topical calcineurin inhibitors have been used to treat vitiligo, either alone or in combination with phototherapy; however, the long-term safety of these agents remains controversial. OBJECTIVE: To investigate the risk of lymphoma and skin cancer in vitiligo patients who received topical calcineurin inhibitors or phototherapy. METHODS: A multicenter retrospective cohort study of 25,694 vitiligo patients who received topical calcineurin inhibitors or phototherapy for 6 weeks or more between 2001 and 2019 was performed. Cumulative doses of topical calcineurin inhibitors and total phototherapy sessions were determined. Outcomes were the development of lymphoma or skin cancer after enrollment, confirmed through chart review and pathology reports. RESULTS: During 95,203 person-years, 13 cases of lymphoma, 22 of actinic keratosis, 15 of nonmelanoma skin cancer, and 5 of melanoma were observed. The risk of lymphoma and skin cancer was not significantly increased by topical calcineurin inhibitor dose or phototherapy sessions. The interaction between the topical calcineurin inhibitors and phototherapy was not associated with an increased risk of skin cancer. LIMITATIONS: Retrospective study, individual follow-up duration less than 4 years, and no adjustment for comorbidities and medication history. Not generalizable to other races. CONCLUSION: The long-term risk of skin cancer or lymphoma was not associated with the use of topical calcineurin inhibitors, phototherapy, and both treatments in combination in patients with vitiligo.

BACKGROUND: The National Comprehensive Cancer Network and American Society of Clinical Oncology recommend consideration of the use of echocardiography 6 to 12 months after completion of anthracycline-based chemotherapy in at-risk populations. Assessment of BNP (B-type natriuretic peptide) has also been suggested by the American College of Cardiology/American Heart Association/Heart Failure Society of America for the identification of Stage A (at risk) heart failure patients. The real-world frequency of the use of these tests in patients after receipt of anthracycline therapy, however, has not been studied previously. METHODS AND RESULTS: In this retrospective study, using administrative claims data from the OptumLabs Data Warehouse, we identified 31 447 breast cancer and lymphoma patients (age ≥18 years) who were treated with an anthracycline in the United States between January 1, 2008 and January 31, 2018. Continuous medical and pharmacy coverage was required for at least 6 months before the initial anthracycline dose and 12 months after the final dose. Only 36.1% of patients had any type of cardiac surveillance (echocardiography, BNP, or cardiac imaging) in the year following completion of anthracycline therapy (29.7% echocardiography). Surveillance rate increased from 37.5% in 2008 to 42.7% in 2018 (25.6% in 2008 to 40.5% echocardiography in 2018). Lymphoma patients had a lower likelihood of any surveillance compared with patients with breast cancer (odds ratio, 0.79 [95% CI, 0.74-0.85]; P<0.001). Patients with preexisting diagnoses of coronary artery disease and arrhythmia had the highest likelihood of cardiac surveillance (odds ratio, 1.54 [95% CI, 1.39-1.69] and odds ratio, 1.42 [95% CI, 1.3-1.53]; P<0.001 for both), although no single comorbidity was associated with a >50% rate of surveillance. CONCLUSIONS: The majority of survivors of breast cancer and lymphoma who have received anthracycline-based chemotherapy do not undergo cardiac surveillance after treatment, including those with a history of cardiovascular comorbidities, such as heart failure.

BACKGROUND: We gathered rural patient perspectives on lymphoma care and unmet needs throughout the treatment course to better understand their attitudes toward treatment and their barriers to participating in clinical research studies. PATIENTS AND METHODS: We conducted 12 individual semi-structured telephone interviews in the spring of 2018 with lymphoma survivors from rural counties in Georgia. Patients were identified by a residential address in counties classified as rural according to the Rural-Urban Commuting Areas codes. Participants were recruited from regional patient education conferences and from current research participants at a university research hospital in Georgia. The interviews were recorded and transcribed verbatim. Thematic analysis and MAXQDA, version 18.0.8, were used to facilitate a constant comparative coding process during theme development. RESULTS: The greatest barrier to care was the travel distance. The participants described difficulty navigating between local clinics and larger cancer centers. The lack of communication between the local and specialized clinics complicated the process, and participants had difficulty contacting or seeking advice from the team at the larger cancer centers. Seeking treatment from specialized clinics farther away introduced additional barriers. Most participants agreed that the use of technology was important for improved communication. Participants described lymphoma etiology, subtype-specific studies, alternative therapies, and quality of life as key research priorities. CONCLUSION: These findings suggest that targeted research and interventions are necessary to address the specific needs of rural patients with and survivors of lymphoma. To address the disparity in health outcomes within rural populations, healthcare professionals and investigators can use these data to engage rural patients in treatment decision-making and research planning.

BACKGROUND: Although the number of lymphoma survivors has increased, the needs and research priorities of survivors and their caregivers rarely are examined and addressed. Determining the needs and priorities for this population requires an assessment of the attitudes and experiences of patients and caregivers. The authors conducted a qualitative study with lymphoma survivors and their caregivers to determine care needs and research priorities. METHODS: In the first phase, 2 semistructured focus groups were conducted with 15 lymphoma survivors and their caregivers. In phase 2, a total of 19 individual semistructured telephone interviews were conducted with lymphoma survivors and their caregivers. In both phases, participants discussed cancer experiences and research priorities. All interviews were transcribed. MAXQDA software (version 18.0.8) was used for coding and identifying themes. RESULTS: The majority of participants felt disconnected from their clinical care team due to a lack of communication. Focus group participants noted a lack of information regarding diagnoses, treatment, research, and survivorship care. Participants coped with fear through strong social support and fostering relationships with their clinical care teams. Some caregivers felt completely ignored by clinicians. Participants expressed interest in research, but had difficulty finding relevant studies. Several interviewees desired holistic and survivorship-oriented research and more studies regarding quality of life and mental health. CONCLUSIONS: The results of the current study identified unmet needs in clinical care and patient-oriented research, including needs for a focus on quality of life after treatment, communication between patients and the scientific community, and emotional well-being. Health care professionals can use these data to provide care delivery, supportive services, and research that meets the needs of lymphoma survivors and their caregivers.

BACKGROUND: Prior evidence of a possible link between vitamin D status and hematologic malignancy (HM) in humans comes from observational studies, leaving unresolved the question of whether a true causal relationship exists. METHODS: The authors performed a secondary analysis of data from the Women's Health Initiative Calcium/Vitamin D (CaD) trial, a large randomized controlled trial of CaD supplementation compared with placebo in older women. Kaplan-Meier and Cox proportional hazards survival analysis methods were used to evaluate the relationship between treatment assignment and 1) incident HM and 2) HM-specific mortality over 10 years following randomization. HMs were classified by cell type (lymphoid, myeloid, or plasma cell) and analyzed as distinct endpoints in secondary analyses. RESULTS: A total of 34,763 Women's Health Initiative CaD trial participants (median age, 63 years) had complete baseline covariate data and were eligible for analysis. Women assigned to CaD supplementation had a significantly lower risk of incident HM (hazard ratio [HR], 0.80; 95% confidence interval [95% CI], 0.65-0.99) but not HM-specific mortality (HR, 0.77 [95% CI, 0.53-1.11] for the entire cohort; and HR, 1.03 [95% CI, 0.70-1.51] among incident HM cases after diagnosis). In secondary analyses, protective associations were found to be most robust for lymphoid malignancies, with HRs of 0.77 (95% CI, 0.59-1.01) and 0.46 (95% CI, 0.24-0.89), respectively, for cancer incidence and mortality in those assigned to CaD supplementation. CONCLUSIONS: The current post hoc analysis of data from a large and well-executed randomized controlled trial demonstrates a protective association between modest CaD supplementation and HM risk in older women. Additional research concerning the relationship between vitamin D and HM is warranted. Cancer 2017;123:4168-4177. © 2017 American Cancer Society.

PURPOSE OF REVIEW: In the present review, recent findings regarding silicone breast implants (SBIs) complicated by rheumatic autoimmune diseases are described. RECENT FINDINGS: Despite changes in the principal constituents of the silicone implants during the past 50 years, silicone remained an adjuvant that may 'bleed' and subsequently may be a chronic stimulus to the immune system resulting in similar clinical manifestations as 50 years ago. Silicones are spread throughout the body and can be detected in tissues and the central nervous system. Autoimmune/inflammatory syndrome by adjuvants (ASIA), allergies, autoimmune diseases, immune deficiencies and lymphomas occur in patients with SBIs. There is a need for adequately adjusted epidemiological studies to ascertain the frequency of these diseases. Explantation of the breast implants, however, should be advised to patients with complaints, as 60-80% of patients show an amelioration of the signs and symptoms after explantation. SUMMARY: SBIs are associated in a proportion of patients with complaints such as fatigue, cognitive impairment, arthralgias, myalgias, pyrexia, dry eyes and dry mouth. Silicones can migrate from the implant through the body and can induce a chronic inflammatory process. Explantation of SBI results in the majority of patients in an amelioration of the symptoms.

The biology of sex differences deals with the study of the disparities between females and males and the related biological mechanisms. Gender medicine focuses on the impact of gender and sex on human physiology, pathophysiology and clinical features of diseases that are common to women and men. The term gender refers to a complex interrelation and integration of sex-as a biological and functional determinant-and psychological and cultural behaviours (due to ethnical, social or religious background). The attention to the impact of gender differences on the pathophysiology and, therefore, on the clinical management of the most common diseases, such as cardiovascular diseases (CVD), neurodegenerative disorders, immune and autoimmune diseases as well as several tumours, is in fact often neglected. Hence, studies covering different fields of investigation and including sex differences in the pathogenesis, in diagnostic and prognostic criteria as well as in response to therapy appear mandatory. However, prerequisites for this development are preclinical studies, including in vitro and in vivo approaches. They represent the first step in the development of a drug or in the comprehension of the pathogenetic mechanisms of diseases, in turn a necessary step for the development of new or more appropriate therapeutic strategies. However, sex differences are still poorly considered and the great majority of preclinical studies do not take into account the relevance of such disparities. In this review, we describe the state of the art of these studies and provide some paradigmatic examples of key fields of investigation, such as oncology, neurology and CVD, where preclinical models should be improved.

Childhood cancer incidence increases and although rare, it is a leading cause of mortality. Leukemia and lymphoma comprise 40% of all cancers in children but little is known of their etiology. In this study, we examined the associations of breastfeeding and other early life exposures with childhood leukemia and lymphoma. A population-based case-control study carried out in 2011-2013 comprised mothers of 190 incidents (2005-2013) of leukemia/lymphoma cases aged 1-19 yr at diagnosis and 384 population-based controls. Interviews based on a computerized structured questionnaire were conducted with the mothers. Multivariate logistic regression models adjusted for potential confounders assessed the association between breastfeeding patterns and childhood leukemia/lymphoma. Ever breastfeeding category was associated with a 64% decreased risk for childhood leukemia/lymphoma lsqb;odds ratio (OR) = 0.36, 95% confidence interval (CI): 0.22, 0.60lrqb; and similar trends, with a dose-response effect, were observed for any breastfeeding (exclusive and/or partial) category for 6, 12, and 18+ mo. Other infant exposures associated with cancer risk were child iron supplementation (OR = 0.39, 95% CI: 0.26, 0.59), pet ownership (OR = 0.50, 95% CI: 0.33, 0.78), paternal smoking (OR = 1.93, 95% CI: 1.18, 3.15), and having older siblings (OR = 1.18, 95% CI: 1.05, 1.33). Breastfeeding-a controllable and modifiable exposure-is inversely associated with risk for childhood leukemia and lymphoma with a dose-response effect.

BACKGROUND: The aim of this work was to examine the risk of lymphohaematopoietic (LH) cancer according to benzene exposure among offshore workers. METHODS: Cancer registry data were used to identify 112 cancer cases diagnosed during 1999-2011 in a cohort of 24 917 Norwegian men reporting offshore work between 1965 and 1999. Analyses were conducted according to a stratified case-cohort design with a reference subcohort of 1661 workers. Cox regression was used to estimate hazard ratios with 95% confidence intervals, adjusted for other benzene exposure and smoking. RESULTS: Most workers were exposed to benzene for <15 years. The upper range values of average intensity and cumulative exposure were estimated to 0.040 p.p.m. and 0.948 p.p.m.-years, respectively. Risks were consistently elevated among exposed workers for all LH cancers combined and for most subgroups, although case numbers were small and yielded imprecise risk estimates. There was evidence of dose-related risk patterns according to cumulative exposure for acute myeloid leukaemia (AML), multiple myeloma (MM) (P trends 0.052 and 0.024, respectively), and suggestively so for chronic lymphocytic leukaemia (CLL) according to average intensity (P trend 0.094). CONCLUSIONS: Our results support an association between cumulative and intensity metrics of low-level benzene exposure and risk for AML, MM, and suggestively for CLL.

BACKGROUND: Fatigue is a common symptom in patients with advanced malignancy, and has been associated with both physiological and psychological factors in patients with solid tumours. AIM: This study sought to explore the predictors of fatigue in a population with haematological malignancy. METHODS: Consecutive outpatients and inpatients attending a haematology centre completed the Memorial Symptom Assessment Scale, and clinical, treatment and demographic information were noted. RESULTS: Of 180 patients, fatigue was present in 69%, and causing considerable distress in 26%. Univariate analysis revealed fatigue was associated with poor performance status, low haemoglobin, feeling sad, worried, irritable and nervous. Multivariate modeling revealed that those factors predictive of fatigue were poor performance status, having active disease, feeling sad and irritable, while haemoglobin level was not predictive of fatigue. CONCLUSIONS: Fatigue is a multidimensional symptom in patients with haematological malignancy whose presence must prompt a holistic assessment of potential contributors that goes beyond correction of haemoglobin levels.

BACKGROUND: Although situated on the last places among the statistical hierarchy of human malignancies, thyroid cancers (TC) are the most common tumors of the endocrine system. Follicular epithelium neoplasms account for more than 90% of these lesions with a favourable prognosis, while resting tumors (medullary, anaplastic, lymphoma, sarcoma etc) generally present a rapid unfavorable evolution with a low rate of survival. PATIENTS AND METHODS: In a series of 464 thyropathies personally treated, 72 cases of TC (15.5%) were identified. Fifty-seven patients presented epithelial TC a 34 papillary variant, 20 follicular variant and 8 mixed forms. Alongside these there were two medullary TC, 9 anaplastic TC and insular TC, and primary lymphoma and metastasis to the thyroid of a lung carcinoma each single case. Four cases have been described in patients who were aged 2-6 years at the time of the Chernobyl disaster. Out of the common types, based on our own taxonomic criteria, we selected a group of 36 TC with unusual clinical, histological and behavioural characteristics or particular pathological associations. RESULTS: Seven cases of occult TC, 7 cases with precessive adenopathy TC and 11 patients with TC associated with hyperthyroidism were registered. All of them underwent adapted thyroidectomies in which the presence of cancer was decisive for the extent of surgery. Medullary, insular and anaplastic TC were the most aggressive lesions and even extended surgery and complementary therapy failed to improve the prognosis of these patients. In the same category we included the cases presenting the coexistence of two TC types, pathologic dedifferentiation in recurrences and concurrent presence of another endocrine or nonendocrine cervical lesion. The a surgical dogma of total thyroidectomy cannot always be respected, so complementary therapeutic solutions must be applied. RESULTS were complex, registering steady recoveries in occult, hyperfunctioning and even in coexisting pathological lesions, but many recurrences and reinterventions with poor survival rates (a few weeks up to 2 years) in cases with reduced or absent histologic differentiation were also noted. Some lesions were inoperable. DISCUSSIONS AND CONCLUSIONS: Increasing clinician, surgeon and pathologist awareness of these distinct, but not rare anatomoclinical contingencies could contribute to their adequate diagnosis and treatment. Recent progress in knowledge of molecular carcinogenesis and promising successes of targeted chemotherapy trials with new drugs offer promising perspectives in the management of advanced or metastatic TC. Surgery still remains the cornerstone treatment for thyroid cancers.

Inflammatory bowel disease in children can be marked by aggressive disease both at presentation and over time. Risk stratification of individual patients may help identify when early biologic therapy is justified. Currently, combination biologic and immunomodulator therapy for moderate-to-severe Crohn's disease is the most effective treatment regimen. The clinician's conundrum arises from the recent understanding that rare but serious adverse events do occur with use of these strong immune suppressive drugs and may be more prevalent with combination therapy. An understanding of the natural history of Crohn's disease and ulcerative colitis and the benefits and risks of the current medical armamentarium is essential to provide optimal care for each child with inflammatory bowel disease.

Despite the recent advances in cancer therapeutics for lymphoma (Lym), a continuum of disease, treatment and psychological challenges, adversely impacting health-related quality of life, remain for the clinical management of the patient with Lym. In response, this study presents the development and validation of the National Comprehensive Cancer Network-Functional Assessment of Cancer Therapy (NCCN-FACT) Lymphoma Symptom Index-18 (FLymSI-18). Patients with advanced Lym (n = 50) rated the significance of 40 symptoms, and hematologist-oncologists (n = 10) rated these symptoms according to importance and disease-related or treatment-related origin. Patient symptom priorities were unified with clinician priorities for symptom measurement in Lym for instrument development. Reliability estimates indicate that FLymSI-18 has acceptable internal consistency (α = 0.87), content validity and concurrent validity as indicated by moderate to strong correlations with the FACIT (Functional Assessment of Chronic Illness Therapy). Overall, the FLymSI-18 provides evidence for its reliability and validity as a brief assessment of the most important symptoms associated with advanced Lym in the clinical trial research environment.

BACKGROUND: Hospitalized psoriasis patients are known to have a higher risk of malignancy (e.g., nonmelanoma skin cancer [NMSC], lymphoma, and melanoma) than the general population; currently, it is unclear whether this risk is affected by psoriasis severity. The aim of this study was to compare the cancer risk of patients with mild and severe psoriasis and the general population. METHODS: Data for this retrospective population-based cohort study were obtained from the Taiwan National Health Insurance Research Database. This study included 7061 patients with a first-time diagnosis of psoriasis. All study individuals were followed up until the end of 2007. The crude incidence density ratio and standardized incidence ratio (SIR) of NMSC, melanoma, and lymphoma were determined. RESULTS: Among psoriasis patients, the most common cancer was NMSC (density ratio: 7.5); women were at a higher risk of NMSC than men (density ratios: 8.08 vs. 7.0). Psoriasis patients in the south geographic group or in the 50- to 59-year-old age group were most likely to develop NMSC. The NMSC SIR was higher among patients with severe psoriasis than among patients with mild psoriasis (SIR: 3.72 vs. 7.08). The lymphoma and melanoma SIR among patients with severe psoriasis was also high (lymphoma SIR: 4.85; melanoma: 11.01). CONCLUSIONS: Psoriasis carries an elevated risk of NMSC and lymphoma.

BACKGROUND: Lymphomatoid papulosis (LyP) is a low-grade cutaneous lymphoma, which lies within the spectrum of primary cutaneous CD30-positive lymphoproliferative disorders. Around 10-20% of LyP cases are associated with a second lymphoma. AIM: To analyse a cohort of Asian patients with LyP, diagnosed from 1987 to 2007 at the National Skin Centre (NSC), Singapore, in terms of epidemiology, treatment and association with a second lymphoma. METHODS: Patients were identified through the NSC clinical and histological databases. RESULTS: During this period, 13 patients were diagnosed with LyP based on clinicopathological criteria. The mean age at diagnosis was 41 years, the male : female ratio was 2.3 : 1, and 92% of the patients were Chinese. Recurrent papulonecrotic lesions were present for a mean of 3 years before diagnosis. Treatment of LyP comprised monotherapy (n = 4) or combination therapy (n = 9) using corticosteroids, oral antibiotics, methotrexate and/or phototherapy. Mean duration of follow-up was 6.4 years. Eight patients (61.5%) were diagnosed with a second lymphoma, either before (n = 2), concurrently with (n = 1) or after (n = 5) the diagnosis of LyP. Mycosis fungoides (MF) was the commonest lymphoma (78%, n = 7), followed by primary cutaneous anaplastic large-cell lymphoma (12%, n = 2). There was one death (mortality rate 7.7%), which occurred in a patient who had developed stage IIA MF after LyP, which subsequently progressed to systemic T-cell lymphoma. CONCLUSIONS: LyP is a chronic, relapsing disease with considerable morbidity, but an overall good prognosis. A strikingly large proportion of our Asian patients (61.5%) had a second lymphoma, compared with previous studies. This emphasizes the importance of regular lifetime surveillance for associated lymphomas in all patients with LyP.
