Cutaneous T-cell lymphoma is associated with increased risk of lymphoma, melanoma, lung cancer, and bladder cancer: A systematic review and meta-analysis

Primary bladder B-cell lymphoma: a rare case report and review of literature

Introduction and importance

Primary bladder lymphoma accounts for a mere fraction of vesical tumours and extranodal lymphomas, which mostly affect women. IGH-BCL2 translocation, which occurs in 80-100% of Western follicular variants but only 60% in Asian communities, must be studied to determine its effects on prognosis and treatment. This study analyses and compares relevant literature and data for the authors' case report.

Case presentation

The authors report a 69-year-old Caucasian female with one gross haematuria episode and no smoking history. Computed tomography (CT) showed a bilateral massive intraluminal mass left ureterovesical junction, hydronephrosis, and hydroureter.

Clinical discussion

Following the removal of a massive transurethral urinary bladder tumour, histological examination revealed lymphoma cells positive for IRTA and LMO2 but negative for IGH-BCL2. After these analyses, the patient received 3 weeks of 30 Gy/15 f IMRT/IGRT. Comparisons were made to previous case reports' histopathology.

Conclusion

The current case report emphasizes the rarity of primary bladder lymphoma and the absence of the IGH-BCL2 fusion gene. Following the successful administration of 30 Gy of radiation therapy, the patient's prognosis improved. The report emphasizes clinical vigilance and timely management while also urging further investigation.

Correlation between second and first primary cancer: systematic review and meta-analysis of 9 million cancer patients

BACKGROUND

Many survivors of a first primary cancer (FPCs) are at risk of developing a second primary cancer (SPC), with effects on patient prognosis. Primary cancers have different frequencies of specific SPC development and the development of SPCs may be closely related to the FPC. The aim of this study was to explore possible correlations between SPCs and FPCs.

METHODS

Relevant literature on SPCs was retrospectively searched and screened from four databases, namely, PubMed, EMBASE, Web of Science, and PMC. Data on the number of patients with SPC in 28 different organ sites were also collected from The Surveillance, Epidemiology, and End Results (SEER) 8 Registry and NHANES database.

RESULTS

A total of 9 617 643 patients with an FPC and 677 430 patients with an SPC were included in the meta-analysis. Patients with a first primary gynaecological cancer and thyroid cancer frequently developed a second primary breast cancer and colorectal cancer. Moreover, those with a first primary head and neck cancer, anal cancer and oesophageal cancer developed a second primary lung cancer more frequently. A second primary lung cancer and prostate cancer was also common among patients with first primary bladder cancer and penile cancer. Patients with second primary bladder cancer accounted for 56% of first primary ureteral cancer patients with SPCs.

CONCLUSIONS

This study recommends close clinical follow-up, monitoring and appropriate interventions in patients with relevant FPCs for better screening and early diagnosis of SPCs.

Allogeneic transplantation and cellular therapies in cutaneous T-cell lymphoma

INTRODUCTION

Mycosis fungoides (MF) and Sezary syndrome (SS) are the most common types of cutaneous T-cell lymphoma. Although many available treatments offer temporary disease control, allogeneic hematopoietic stem cell transplant (allo-HSCT) is the only curative treatment option for advanced stage MF and SS. CAR T-cell therapy is a promising new avenue for treatment.

AREAS COVERED

In this review, we discuss the evidence supporting the use of allo-HSCT for the treatment of MF/SS, including disease status at the time of transplant, conditioning regimen, total body irradiation (TBI), and donor lymphocyte infusion (DLI). We also address the potential role for CAR T-cell therapy in CTCL.

EXPERT OPINION

Allo-HSCT is an effective treatment for patients with advanced MF and SS. However, significant research is required to determine optimal treatment protocols. Data support the use of reduced-intensity conditioning regimens and suggests that the use of TBI for debulking of skin disease may result in more durable remissions. Donor lymphocyte infusions (DLI) appear to be particularly effective in inducing complete remission in MF/SS patients with relapsed or residual disease. Challenges with CAR-T therapies in T-cell lymphoma include T-cell fratricide due to shared antigens on malignant and nonmalignant T-cells, penetrance into the skin compartment, and CAR-T cell persistence.

Risk of skin cancers in mycosis fungoides patients receiving PUVA therapy: A real-life experience from a single tertiary center

BACKGROUND

Mycosis fungoides (MF) is the most common cutaneous T-cell lymphoma. Skin-directed therapies, including phototherapy, are the first-line treatment modalities. Psoralen plus ultraviolet A light photochemotherapy (PUVA) is quite effective in controlling the disease; however, long-term adverse effects, particularly carcinogenesis, are the cons of this treatment.

OBJECTIVE

There are various studies on the negative impact of PUVA on skin cancer in patients with autoimmune skin diseases. The data on the long-term effects of phototherapy on MF patients are scarce.

METHODS

All MF cases that received PUVA alone or combined with other treatments at a single tertiary center were analyzed. This study compared the development of non-melanoma skin cancers, melanoma, and solid organ tumors in MF patients with at least 5-year follow-up data with age- and sex-matched controls.

RESULTS

A total of 104 patients were included in the study. Ninety-two malignancies were detected in 16 (15.4%) patients, and six developed multiple malignancies. Skin cancers consisted of 56 basal cell carcinomas, 16 Bowen's disease, four squamous cell carcinomas, three melanomas, two basosquamous cell carcinomas, one Kaposi sarcoma, and one keratoacanthoma were found in nine (8.7%) patients. Eight patients developed three solid cancers and six lymphomas. The risk of developing skin cancer was associated with the total number of PUVA sessions (<250 vs ≥250 sessions; hazard ratio (HR) 4.44, 95% confidence interval (CI) 1.033-19.068; p = .045). 9 (13.2%) of 68 patients who had follow-ups for at least 5 years developed skin cancer. Compared to an age- and sex-matched cohort, the prevalence of new skin cancer was considerably greater (p = .009).

CONCLUSIONS

Patients with MF are predisposed to develop secondary malignancies, and continual exposure to PUVA may potentiate this risk. Annual digital dermoscopic follow-up in MF patients treated with UVA is advised for early diagnosis and treatment of secondary cutaneous malignancies.

Incidence of cutaneous melanoma and Merkel cell carcinoma in patients with primary cutaneous B-cell lymphomas: A population study of the SEER registry

Introduction

The increased incidence of cutaneous melanoma (CM) and Merkel cell carcinoma (MCC) in patients with hematologic malignancies (HM) is well established. While the risk of CM has been assessed in some subtypes of HM including cutaneous T-cell lymphoma, the incidence in patients with primary cutaneous B-cell lymphoma (PCBCL) has not been interrogated.

Methods

Here we evaluated the standardized incidence ratio (SIR) of CM and MCC in 5,179 PCBCL patients compared to approximately 1.5 billion individuals in the general population using the Surveillance, Epidemiology and End Results (SEER) database. Among patients with PCBCL, we identified subgroups that were at increased risk for CM or MCC as a second primary cancer.

Results

We found 36 cases of CM in the PCBCL cohort (SIR, 1.35; 95% CI, 0.94–1.86), among which SIR was significantly elevated for non-Hispanic White patients compared to the general population (SIR, 1.48; 95% CI, 1.03–2.06). Males had a significantly increased risk of developing CM after a diagnosis of PCBCL (SIR, 1.60; 95% CI, 1.10–2.26). We found that males in the age group of 50–59 were at increased risk for CM development (SIR, 3.02; 95% CI, 1.11–6.58). Males were at increased risk of CM 1–5 years after PCBCL diagnosis (SIR, 2.06; 95% CI, 1.18–3.34). Patients were at greater risk of developing MCC within 1 year of diagnosis of PCBCL (SIR, 23.60; 95% CI, 2.86–85.27), particularly in patients who were over the age of 80 (SIR, 46.50; 95% CI, 5.63–167.96). Males aged 60–69 with PCBCL, subtype marginal zone, were also at increased risk for MCC (SIR, 42.71; 95% CI, 1.08–237.99).

Conclusion

There is an increased incidence of CM in White, middle-aged males within 5 years of diagnosis of PCBCL and an increased risk of MCC in elderly patients within 1 year of PCBCL diagnosis. These data suggest that certain subgroups of patients with PCBCL may require more rigid surveillance for CM and MCC.

Cutaneous T-cell lymphomas: 2023 update on diagnosis, risk-stratification, and management

DISEASE OVERVIEW

Cutaneous T-cell lymphomas are a heterogenous group of T-cell neoplasms involving the skin, the majority of which may be classified as Mycosis Fungoides (MF) or Sézary Syndrome (SS).

DIAGNOSIS

The diagnosis of MF or SS requires the integration of clinical and histopathologic data.

RISK-ADAPTED THERAPY

TNMB (tumor, node, metastasis, blood) staging remains the most important prognostic factor in MF/SS and forms the basis for a "risk-adapted," multidisciplinary approach to treatment. For patients with disease limited to the skin, expectant management or skin-directed therapies is preferred, as both disease-specific and overall survival for these patients is favorable. In contrast, patients with advanced-stage disease with significant nodal, visceral or the blood involvement are generally approached with systemic therapies, including biologic-response modifiers, histone deacetylase inhibitors, or antibody-based strategies, in an escalating fashion. In highly-selected patients, allogeneic stem-cell transplantation may be considered, as this may be curative in some patients.

Primary cutaneous lymphoma patients seen at a referral dermatological centre in 1 year: A single-centre observational retrospective cohort study of the diagnoses and staging, comorbidities and associated symptoms, treatment performed and clinical course

IMPORTANCE

Primary cutaneous lymphomas (PCL) are rare diseases, but the indolent course makes their prevalence high. Although there are many treatment options, no hierarchy is recommended.

OBJECTIVE

To identify the burden of PCL and describe clinical-pathologic features; associated comorbidities; analyse treatment approaches in real-life and the parameters associated with the achievement of complete response (CR).

DESIGN, SETTING AND PARTICIPANTS

In this study, all the PCL patients (384 patients) consecutively seen at the Dermatologic Clinic of the University of Turin from January 1, 2019 to December 31, 2019, with follow-up updated to December 2020, were included.

MAIN OUTCOMES AND MEASURES

Subtype of PCL, demographic data, time elapsed between first lesions and diagnosis, associated symptoms, comorbidities, staging at diagnosis, high-grade transformation, blood involvement, stage progression, therapies used and response were assessed.

RESULTS

247 were cutaneous T-cell lymphomas (CTCL, 64.3%), 137 cutaneous B-cell lymphomas (CBCL, 35.7%) and the most frequent subtype was MF (48.4%). 62.3% of CTCL patients showed at least one comorbidity, mainly cardiovascular (28.7%), 20.2% show other not cutaneous neoplasms. The main approaches were skin-directed therapies (topical steroids 65.6%; phototherapy 50.2%). 39.3% patients achieved a CR during the disease course. Pruritus, the presence of comorbidities and high-grade transformation were factors associated with failure to achieve CR, whereas stage IA of MF was associated with greater achievement of CR.

CONCLUSIONS AND RELEVANCE

The Th2 cytokine related development of pruritus could justify increased resistance to treatment, while the presence of associated comorbidities could reduce treatment options as well as treatment compliance.

The risk of developing second primary malignancies among colorectal cancer patients

Background: The increasing number of young colorectal cancer (CRC) survivors has led to ongoing concerns about the risk of secondary primary malignancies (SPMs). Here, we intended to comprehensively explore the pooled standardized incidence rates (SIRs) for total and site-specific SPMs in CRC survivors with different restriction to lag period.

Methods: Pubmed, Embase, Cochrane Library, and Web of science databases were searched to identify any studies reporting the SIRs of SPM following CRC until August 2021. Total and site-specific SIRs with different restriction to lag period were pooled using fixed/random effect models.

Results: A total of 42 full-text publications with more than 1, 524, 236 CRC survivors and 166, 210 SPM patients were included in the meta-analysis. Pooled data showed an increased SIRs for all SPMs in CRC survivors with different restriction to lag period (no restriction to lag period, SIR = 1.15, 95% CI = [1.08–1.23]; 1-year lag, 1.16 [1.10–1.23]; 5-year lag, 1.18 [1.09–1.28]; 10-year lag, 1.24 [1.11–1.39]). The conclusions were consistent for neoplasms of colorectum, corpus uteri, and small intestine with different restriction to lag period. However, limited evidence was presented for associations between CRC survivors and SPM for prostate, breast (female), ovarian, stomach, urinary bladder, kidney, thyroid, bone and soft tissue.

Conclusion: CRC survivors are associated with an increased risk of SPMs, especially neoplasms of colorectum, corpus uteri, and small intestine. Further studies should explore the risks for these neoplasms in CRC survivors, thus providing the reference for future follow-up care.

Cutaneous Localization of Classic Hodgkin Lymphoma Associated with Mycosis Fungoides: Report of a Rare Event and Review of the Literature

Mycosis fungoides and nodal classic Hodgkin lymphoma (cHL) have been reported to occur concurrently or sequentially in the same patient. A long-lasting mycosis fungoides more often precedes the onset of nodal cHL, although few cases of nodal cHL followed by mycosis fungoides have been observed. Skin involvement is a rare manifestation of cHL that may be observed in the setting of advanced disease. The decrease in skin involvement in cHL is mainly due to the improved therapeutic strategies. The concurrent presence of mycosis fungoides and cutaneous localization of classic Hodgkin lymphoma represents a very uncommon event, with only two cases reported so far. Herein, we describe the case of a 71-year-old man, with a history of recurrent nodal cHL, who developed MF and, subsequently, the cutaneous localization of cHL. The clinicopathological features of the two diseases are described focusing on the main differential diagnoses to be taken into consideration, and a review of the literature is performed.

Screening for second malignancies in mycosis fungoides: non-Hodgkin lymphoma, Hodgkin lymphoma, lung cancer, bladder cancer and melanoma

BACKGROUND

Patients with mycosis fungoides (MF) are at increased risk of developing non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), lung cancer, bladder cancer and melanoma. The characteristics of patients developing these malignancies have not been specifically delineated. In addition, there are no established guidelines for screening MF patients for second malignancies.

MATERIALS/METHODS

We identified 742 patients with MF who developed second malignancies in the Surveillance Epidemiology and End Result-18 database.

RESULTS

The majority of second malignancy patients were white and male, mean age 55-67 years at diagnosis of MF, and mean age 61-72 years at diagnosis of second malignancy. The majority of patients diagnosed with second malignancies had early stage MF. MF patients with NHL, lung cancer, and bladder cancer tended to be diagnosed at earlier stages of the second malignancy than patients without MF and demonstrated better 5-year overall survival. There was no improvement in stage at diagnosis or survival for MF patients who were diagnosed with melanoma compared to patients without MF.

CONCLUSIONS

Improvements in survival in MF/NHL, MF/lung cancer and MF/bladder cancer patients may reflect differences in disease biology secondary to having MF or the importance of increased contact with the healthcare system. MF/melanoma data suggest that patients require regular pigmented-lesion-focused skin examinations. Tools for screening include regular lymph node examinations, pigmented-lesion-focused examinations and detailed review of systems questions. Smoking cessation counseling is key intervention in this population, as is ensuring that all age- and sex-specific cancer screenings are up-to-date (e.g. lung cancer screening, mammography, and colonoscopy). The utility of regular imaging for second malignancy screening and lab testing such as routine urinalysis requires additional study and expert consensus.

CD4-Targeted T Cells Rapidly Induce Remissions in Mice with T Cell Lymphoma

OBJECTIVE

To explore the immune cell therapy for T cell lymphoma, we developed CD4-specific chimeric antigen receptor- (CAR-) engineered T cells (CD4CART), and the cytotoxic effects of CD4CART cells were determined in vitro and in vivo.

METHODS

CD4CART cells were obtained by transduction of lentiviral vector encoding a single-chain antibody fragment (scFv) specific for CD4 antigen, costimulatory factor CD28 fragment, and intracellular signal transduction domain of CD3 fragments. Control T cells were obtained by transduction of reporter lentiviral vector. The cytotoxicity, tumor growth, and survival rate of mice with T cell lymphoma were analyzed after adoptive T cell transfer in vivo.

RESULTS

CD4CART cells had potent cytotoxic activity against CD4+ T1301 tumor T cells in a concentration-dependent manner. In addition, adoptive CD4CART cell transfer significantly suppressed tumor growth and improved animal survival with T cell lymphoma, compared to the mice who received control T cells and PBS.

CONCLUSION

CD4CART cells have potent cytotoxic effects on T cell lymphoma. The study provided an experimental basis for CD4CART-mediated therapy of T cell lymphoma.
