Health-related quality of life and its influencing factors in patients with primary cutaneous B-cell lymphomas: A multicentric study in 100 patients

BACKGROUND

Primary cutaneous B-cell lymphomas (CBCL) are a group of rare malignant skin diseases that represent approximately 20%-30% of all primary cutaneous lymphomas (PCL). Previous studies revealed impaired health-related quality of life (HRQoL) in patients diagnosed with primary cutaneous T-cell lymphoma (CTCL). Currently, only small-sized studies investigated HRQoL in CBCL patients and lacked detailed analysis of respective subtypes.

OBJECTIVES

This study aims to investigate HRQoL in CBCL patients to identify independent factors of HRQoL impairment in CBCL patients.

METHODS

One hundred CBCL patients were recruited from eight German PCL centres in this multicentric, cross-sectional study from 2021 to 2022. The patients completed the dermatologic HRQoL questionnaire Skindex-29 and an investigator-designed 'CBCL-Questionnaire' with additional questions on HRQoL and clinical characteristics.

RESULTS

The Skindex-29 revealed that HRQoL in CBCL patients is impaired on a mild to moderate level. The multiple regression analysis identified parameters like worries about dying, feeling prejudiced/discriminated and impairment of daily activities to be independently associated with impairment of HRQoL. Highest scores for HRQoL impairment were found in patients with primary cutaneous follicle centre lymphoma while on rituximab treatment and in patients with primary cutaneous marginal zone lymphoma while on watchful waiting.

CONCLUSIONS

HRQoL is impaired in CBCL patients, even though, in the face of indolent disease course and favourable prognosis in the majority of cases. Of note, our investigator-designed tool identified worries about dying, feeling prejudiced/discriminated, and the type of treatment to have a negative impact on patients' HRQoL. Our study highlights the importance of a thorough patient-doctor communication to capture overall disease burden because generic HRQoL tools might lack of disease-specific items.

Pan-immune-inflammation value independently predicts disease recurrence in patients with Merkel cell carcinoma

Purpose

We aimed to determine whether the pan-immune-inflammation value (PIV) of patients with Merkel cell carcinoma (MCC) at primary diagnosis differs from controls and whether it is associated with disease stage and outcome.

Methods

In this retrospective study, we recruited MCC patients with stage I–III. PIV was calculated from absolute complete blood cell counts obtained within one week at MCC diagnosis as follows: [neutrophils (10³/mm³) × platelets (10³/mm³) × monocytes (10³/mm³)]/lymphocytes (10³/mm³). As controls, we studied age–gender-matched cutaneous melanoma (CM, stage I–III) patients and healthy controls (HC). Univariate and multivariate statistics were used.

Results

The median PIV in MCC patients was significantly increased compared to both CM patients as well as healthy controls. PIV of MCC patients in stage II and III was significantly higher compared to stage I patients. ROC analysis revealed that MCC recurrence was significantly associated with a PIV greater than 372 [p < 0.0001, Youden index 0.58; hazard ratio: 4 (95% confidence interval: 1.7 to 9.2)]. In multivariate analysis, only a PIV greater than 372 and higher MCC stage were determined as independent predictors for disease recurrence.

Conclusion

We determined, for the first time, the prognostic ability of the promising blood-based biomarker PIV in MCC patients and observed that PIV is increased in MCC patients in dependence on disease stage and independently predicts MCC recurrence.

Treatment of early-stage mycosis fungoides: results from the PROspective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) study

BACKGROUND

The PROspective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) study is a prospective analysis of an international database. Here we examine front-line treatments and quality of life (QoL) in patients with newly diagnosed mycosis fungoides (MF).

OBJECTIVES

To identify (i) differences in first-line approaches according to tumour-nodes-metastasis-blood (TNMB) staging; (ii) parameters related to a first-line systemic approach and (iii) response rates and QoL measures.

METHODS

In total, 395 newly diagnosed patients with early-stage MF (stage IA-IIA) were recruited from 41 centres in 17 countries between 1 January 2015 and 31 December 2018 following central clinicopathological review.

RESULTS

The most common first-line therapy was skin-directed therapy (SDT) (322 cases, 81·5%), while a smaller percentage (44 cases, 11·1%) received systemic therapy. Expectant observation was used in 7·3%. In univariate analysis, the use of systemic therapy was significantly associated with higher clinical stage (IA, 6%; IB, 14%; IIA, 20%; IA-IB vs. IIA, P < 0·001), presence of plaques (T1a/T2a, 5%; T1b/T2b, 17%; P < 0·001), higher modified Severity Weighted Assessment Tool (> 10, 15%; ≤ 10, 7%; P = 0·01) and folliculotropic MF (FMF) (24% vs. 12%, P = 0·001). Multivariate analysis demonstrated significant associations with the presence of plaques (T1b/T2b vs. T1a/T2a, odds ratio 3·07) and FMF (odds ratio 2·83). The overall response rate (ORR) to first-line SDT was 73%, while the ORR to first-line systemic treatments was lower (57%) (P = 0·027). Health-related QoL improved significantly both in patients with responsive disease and in those with stable disease.

CONCLUSIONS

Disease characteristics such as presence of plaques and FMF influence physician treatment choices, and SDT was superior to systemic therapy even in patients with such disease characteristics. Consequently, future treatment guidelines for early-stage MF need to address these issues.

Should we be imaging lymph nodes at initial diagnosis of early-stage mycosis fungoides? Results from the PROspective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) international study

BACKGROUND

Early-stage mycosis fungoides (MF) includes involvement of dermatopathic lymph nodes (LNs) or early lymphomatous LNs. There is a lack of unanimity among current guidelines regarding the indications for initial staging imaging in early-stage presentation of MF in the absence of enlarged palpable LNs.

OBJECTIVES

To investigate how often imaging is performed in patients with early-stage presentation of MF, to assess the yield of LN imaging, and to determine what disease characteristics promoted imaging.

METHODS

A review of clinicopathologically confirmed newly diagnosed patients with cutaneous patch/plaque (T1/T2) MF from PROspective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) data.

RESULTS

PROCLIPI enrolled 375 patients with stage T1/T2 MF: 304 with classical MF and 71 with folliculotropic MF. Imaging was performed in 169 patients (45%): 83 with computed tomography, 18 with positron emission tomography-computed tomography and 68 with ultrasound. Only nine of these (5%) had palpable enlarged (≥ 15 mm) LNs, with an over-representation of plaques, irrespectively of the 10% body surface area cutoff that distinguishes T1 from T2. Folliculotropic MF was not more frequently imaged than classical MF. Radiologically enlarged LNs (≥ 15 mm) were detected in 30 patients (18%); only seven had clinical lymphadenopathy. On multivariate analysis, plaque presentation was the sole parameter significantly associated with radiologically enlarged LNs. Imaging of only clinically enlarged LNs upstaged 4% of patients (seven of 169) to at least IIA, whereas nonselective imaging upstaged another 14% (24 of 169). LN biopsy, performed in eight of 30 patients, identified N3 (extensive lymphomatous involvement) in two and N1 (dermatopathic changes) in six.

CONCLUSIONS

Physical examination was a poor determinant of LN enlargement or involvement. Presence of plaques was associated with a significant increase in identification of enlarged or involved LNs in patients with early-stage presentation of MF, which may be important when deciding who to image. Imaging increases the detection rate of stage IIA MF, and identifies rare cases of extensive lymphomatous nodes, upstaging them to advanced-stage IVA2.

SARS-CoV-2 spike protein is present in both endothelial and eccrine cells of a chilblain-like skin lesion

Data on SARS‐CoV‐2 detection in lesional skin is controversial.^1‐8 We report a PCR‐proven COVID‐19 patient with a chilblain‐like SARS‐CoV‐2 positive skin lesion. An 80‐year‐old woman presented to the emergency department at the End of March 2020. She reported an onset of fever (38.4 C°) several days before admission, along with cough and shortness of breath. RT‐PCR from a nasopharyngeal swab was positive for SARS‐CoV‐2. An X‐ray showed evidence for right‐sided pneumonic infiltrates.

Clinical diversity and treatment approaches to blastic plasmacytoid dendritic cell neoplasm: a retrospective multicentre study

BACKGROUND

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare, aggressive type of haematologic precursor malignancy primarily often manifesting in the skin. We sought to provide a thorough clinical characterization and report our experience on therapeutic approaches to BPDCN.

METHODS

In the present multicentric retrospective study, we collected all BPDCN cases occurring between 05/1999 and 03/2018 in 10 secondary care centres of the German-Swiss-Austrian cutaneous lymphoma working group.

RESULTS

A total of 37 BPDCN cases were identified and included. Almost 90% of the patients had systemic manifestations (bone marrow, lymph nodes, peripheral blood) in addition to skin involvement. The latter presented with various types of cutaneous lesions: nodular (in more than 2/3) and bruise-like (in 1/3) skin lesions, but also maculopapular exanthema (in circa 1/6). Therapeutically, 22 patients received diverse combinations of chemotherapeutic regimens and/or radiotherapy. Despite initial responses, all of them ultimately relapsed and died from progressive disease. Eleven patients underwent haematopoietic stem cell transplantation (HSCT; autologous HSCT n = 3, allo-HSCT n = 8). The mortality rate among HSCT patients was only 33.33% with a median survival time of 60.5 months.

CONCLUSION

Our study demonstrates the clinical diversity of cutaneous BPDCN manifestations and the positive development observed after the introduction of HSCT.

The PROCLIPI international registry of early-stage mycosis fungoides identifies substantial diagnostic delay in most patients

BACKGROUND

Survival in mycosis fungoides (MF) is varied and may be poor. The PROCLIPI (PROspective Cutaneous Lymphoma International Prognostic Index) study is a web-based data collection system for early-stage MF with legal data-sharing agreements permitting international collaboration in a rare cancer with complex pathology. Clinicopathological data must be 100% complete and in-built intelligence in the database system ensures accurate staging.

OBJECTIVES

To develop a prognostic index for MF.

METHODS

Predefined datasets for clinical, haematological, radiological, immunohistochemical, genotypic, treatment and quality of life are collected at first diagnosis of MF and annually to test against survival. Biobanked tissue samples are recorded within a Federated Biobank for translational studies.

RESULTS

In total, 430 patients were enrolled from 29 centres in 15 countries spanning five continents. Altogether, 348 were confirmed as having early-stage MF at central review. The majority had classical MF (81·6%) with a CD4 phenotype (88·2%). Folliculotropic MF was diagnosed in 17·8%. Most presented with stage I (IA: 49·4%; IB: 42·8%), but 7·8% presented with enlarged lymph nodes (stage IIA). A diagnostic delay between first symptom development and initial diagnosis was frequent [85·6%; median delay 36 months (interquartile range 12-90)]. This highlights the difficulties in accurate diagnosis, which includes lack of a singular diagnostic test for MF.

CONCLUSIONS

This confirmed early-stage MF cohort is being followed-up to identify prognostic factors, which may allow better management and improve survival by identifying patients at risk of disease progression. This study design is a useful model for collaboration in other rare diseases, especially where pathological diagnosis can be complex.

Global patterns of care in advanced stage mycosis fungoides/Sezary syndrome: a multicenter retrospective follow-up study from the Cutaneous Lymphoma International Consortium

BACKGROUND

Advanced-stage mycosis fungoides (MF)/Sézary syndrome (SS) patients are weighted by an unfavorable prognosis and share an unmet clinical need of effective treatments. International guidelines are available detailing treatment options for the different stages but without recommending treatments in any particular order due to lack of comparative trials. The aims of this second CLIC study were to retrospectively analyze the pattern of care worldwide for advanced-stage MF/SS patients, the distribution of treatments according to geographical areas (USA versus non-USA), and whether the heterogeneity of approaches has potential impact on survival.

PATIENTS AND METHODS

This study included 853 patients from 21 specialist centers (14 European, 4 USA, 1 each Australian, Brazilian, and Japanese).

RESULTS

Heterogeneity of treatment approaches was found, with up to 24 different modalities or combinations used as first-line and 36% of patients receiving four or more treatments. Stage IIB disease was most frequently treated by total-skin-electron-beam radiotherapy, bexarotene and gemcitabine; erythrodermic and SS patients by extracorporeal photochemotherapy, and stage IVA2 by polychemotherapy. Significant differences were found between USA and non-USA centers, with bexarotene, photopheresis and histone deacetylase inhibitors most frequently prescribed for first-line treatment in USA while phototherapy, interferon, chlorambucil and gemcitabine in non-USA centers. These differences did not significantly impact on survival. However, when considering death and therapy change as competing risk events and the impact of first treatment line on both events, both monochemotherapy (SHR = 2.07) and polychemotherapy (SHR = 1.69) showed elevated relative risks.

CONCLUSION

This large multicenter retrospective study shows that there exist a large treatment heterogeneity in advanced MF/SS and differences between USA and non-USA centers but these were not related to survival, while our data reveal that chemotherapy as first treatment is associated with a higher risk of death and/or change of therapy and thus other therapeutic options should be preferable as first treatment approach.

[Role of stem cell transplantation in treatment of primary cutaneous T‑cell lymphoma]

BACKGROUND

Within the heterogeneous group of cutaneous T‑cell lymphomas (CTCL) the therapeutic options for advanced and progressive forms are particularly limited.

OBJECTIVE

The therapeutic value of hematopoietic stem cell transplantation in CTCL was analyzed.

MATERIAL AND METHODS

A literature search using the keywords "hematopoietic stem cell transplantation" and "cutaneous T‑cell lymphoma" was performed in PubMed. Studies between 1990 and 2017 were taken into account. The studies identified were analyzed for relevance and being up to date.

RESULTS

After reviewing the currently available literature no prospective randomized studies were found. Wu et al. showed a superiority of allogeneic transplantation in a comparison of autologous and allogeneic stem cell transplantation for cutaneous lymphoma. The graft-versus-lymphoma effect plays a significant role in a prolonged progression-free survival after allogeneic transplantation. By using a non-myeloablative conditioning regimen, stem cell transplantation can also be an option for elderly patients. The most extensive long-term data after allogeneic stem cell transplantation were reported by Duarte et al. in 2014.

CONCLUSION

Autologous stem cell transplantation does not currently represent a therapeutic option, whereas allogeneic stem cell transplantation for advanced cutaneous T‑cell lymphoma, using a non-myeloablative conditioning scheme, does represent a therapeutic option. However, there is no consensus on the appropriate patients and the right timing. Morbidity and mortality of complications should be taken into account. Thus, this procedure is currently subject to an individual case decision.

[HIV window period. Acute retroviral syndrome]

A 24-year-old man with no significant medical history was admitted to this hospital because of an acute exanthema, myalgia and malaise. A fourth-generation screening test for HIV was reactive but the following confirmation test was not. Although the patient did not belong to a high risk group, we decided to perform a HIV-RNA-PCR. The result showed a high virus load so that we finally diagnosed a primary HIV infection.
