Cure indicators and prevalence by stage at diagnosis for breast and colorectal cancer patients: A population-based study in Italy.

People alive many years after breast (BC) or colorectal cancer (CRC) diagnoses are increasing. This paper aimed to estimate the indicators of cancer cure and complete prevalence for Italian patients with BC and CRC by stage and age. A total of 31 Italian Cancer Registries (47% of the population) data until 2017 were included. Mixture cure models allowed estimation of net survival (NS); cure fraction (CF); time to cure (TTC, 5-year conditional NS >95%); cure prevalence (who will not die of cancer); and already cured (prevalent patients living longer than TTC). 2.6% of all Italian women (806,410) were alive in 2018 after BC and 88% will not die of BC. For those diagnosed in 2010, CF was 73%, 99% when diagnosed at stage I, 81% at stage II, and 36% at stages III-IV. For all stages combined, TTC was >10 years under 45 and over 65 years and for women with advanced stages, but ≤1 year for all BC patients at stage I. The proportion of already cured prevalent BC women was 75% (94% at stage I). Prevalent CRC cases were 422,407 (0.7% of the Italian population), 90% will not die of CRC. For CRC patients, CF was 56%, 92% at stage I, 71% at stage II, and 35% at stages III-IV. TTC was ≤10 years for all age groups and stages. Already cured were 59% of all prevalent CRC patients (93% at stage I). Cancer cure indicators by stage may contribute to appropriate follow-up in the years after diagnosis, thus avoiding patients' discrimination.

Indicators of cure for women living after uterine and ovarian cancers: a population-based study.

This study aims to estimate long-term survival, cancer prevalence, and several cure indicators for Italian women with gynaecological cancers. Thirty-one cancer registries, representing 47% of the Italian female population, were included. Mixture cure models were used to estimate Net Survival (NS), Cure Fraction, Time To Cure (5-year conditional NS>95%), Cure Prevalence (women who will not die of cancer), and Already Cured (living longer than Time to Cure). In 2018, 0.4% (121,704) of Italian women were alive after corpus uteri cancer, 0.2% (52,551) after cervical, and 0.2% (52,153) after ovarian cancer. More than 90% of patients with uterine cancers and 83% with ovarian cancer will not die from their neoplasm (Cure Prevalence). Women with gynaecological cancers have a residual excess risk of death <5% after 5 years since diagnosis. The Cure Fraction was 69% for corpus uteri, 32% for ovarian, and 58% for cervical cancer patients. Time To Cure was ≤10 years for women with gynaecological cancers aged <55 years. 74% of patients with cervical cancer, 63% with corpus uteri cancer, and 55% with ovarian cancer were Already Cured. These results will contribute to improving follow-up programs for women with gynaecological cancers and supporting efforts against discrimination of already cured ones.

Impact of the COVID-19 pandemic, its related social restriction measures and vaccination campaign on emergency department attendances for epileptic seizures: An interrupted time-series analysis.

AIM: To investigate the impact of the outbreak of the COVID-19 pandemic, its related social restriction measure (national lockdown) and vaccination campaign on emergency department (ED) accesses for epileptic seizures. METHODS: Retrospective observational analysis conducted on a consecutive cohort of patients who sought medical care at the ED of the General Hospital of Merano, Italy, from January 1, 2015, to December 31, 2021. We investigated the monthly ED attendances for epileptic seizures between the periods before and after the outbreak of the COVID-19 pandemic and the national lockdown (March 2020) using an interrupted time-series analysis with data standardized for 1000 accesses/month. As a further temporal cutoff, we used the start of the national vaccination campaign. RESULTS: Between January 1, 2015, and December 31, 2021, a total of 415,005 ED attendances were recorded; 1,254 (0.3 %) were due to epileptic seizures. No significant difference was found in the rate of standardized ED accesses for epileptic seizures in March 2020 (time point of interest) to the pre-pandemic trend (0.33/1000; 95 %CI: -1.05 to 1.71; p = 0.637). Similarly, there was no difference between the pre- and post-pandemic trends (-0.02/1000; 95 %CI: -0.11 to 0.06; p = 0.600). When adopting January 2021 as time point of interest, we found no difference to the pre-vaccination trend (0.83/1000; 95 %CI: -0.48 to 2.15), and no difference in the pre- and post-vaccination trends (-0.12/1000; 95 %CI: -0.27 to 0.04). CONCLUSIONS: The COVID-19 pandemic and its related social restrictions (lockdown), as well as the COVID-19 national vaccination campaign, had little impact on ED accesses for epileptic seizures.

Human intelligence versus Chat-GPT: who performs better in correctly classifying patients in triage?

INTRODUCTION: Chat-GPT is rapidly emerging as a promising and potentially revolutionary tool in medicine. One of its possible applications is the stratification of patients according to the severity of clinical conditions and prognosis during the triage evaluation in the emergency department (ED). METHODS: Using a randomly selected sample of 30 vignettes recreated from real clinical cases, we compared the concordance in risk stratification of ED patients between healthcare personnel and Chat-GPT. The concordance was assessed with Cohen's kappa, and the performance was evaluated with the area under the receiver operating characteristic curve (AUROC) curves. Among the outcomes, we considered mortality within 72 h, the need for hospitalization, and the presence of a severe or time-dependent condition. RESULTS: The concordance in triage code assignment between triage nurses and Chat-GPT was 0.278 (unweighted Cohen's kappa; 95% confidence intervals: 0.231-0.388). For all outcomes, the ROC values were higher for the triage nurses. The most relevant difference was found in 72-h mortality, where triage nurses showed an AUROC of 0.910 (0.757-1.000) compared to only 0.669 (0.153-1.000) for Chat-GPT. CONCLUSIONS: The current level of Chat-GPT reliability is insufficient to make it a valid substitute for the expertise of triage nurses in prioritizing ED patients. Further developments are required to enhance the safety and effectiveness of AI for risk stratification of ED patients.

Equated hospitalization rate of patients with inflammatory rheumatic diseases as compared to normal population in 2°wave SARSCoV2 infection.

OBJECTIVE: To investigate the clinical manifestations and outcome of COVID-19 in patients with inflammatory rheumatic and musculoskeletal disease (iRMD) as compared with the general population. METHODS: This is a case-control study of patients selected from the South-Tyrol public health service-Italy with and without iRMD affected by COVID-19. We included patients ≥18 years and with a positive SARS-CoV-2 PCR test between 1.10.2020 and 01.03.2021. Cases were identified by linking the diagnosis of a rheumatic disease with PCR test positivity; these were matched in a 1:1.8 (planned 1:2) ratio for age, sex, and date of COVID-19 diagnosis with people from the general population. The outcomes of primary interest were hospitalization and severe course (intensive care unit, mechanical ventilation/extracorporeal membrane oxygenation, death). RESULTS: The study population consisted of 561 COVID-19 patients, of which 201 (mean age 60.4 years; 65.2% female) were patients with iRMD and 360 were controls from the general population (59.8 years; 64.7% female). The majority of iRMD patients (88.6%) received an immunosuppressive drug at time of COVID-19 diagnosis, 36.3% were under glucocorticoids. COVID-19 related hospitalization (12.4% vs 10.6%, p= 0.49), severe course (5.0% vs 5.3%, p= 1.00), and mortality (3.5% vs 4.4%, p= 0.66) were similar between groups. Among hospitalized patients, mechanic ventilation was more common in iRMD patients than in controls [n = 5 (20.0%) vs n = 1 (2.6%), p= 0.035]. CONCLUSIONS: Our study indicates similar rates for admission, severe course and mortality between patients with iRMD and controls affected by COVID-19. Among hospitalized patients, mechanical ventilation was more frequently required in the iRMD group.

Obinutuzumab does not improve complete methabolic response but does not compromise mobilization or engraftment of autologous peripheral blood stem cells in diffuse large B cell lymphoma: Results from a fondazione italiana linfomi prospective phase II study (the GIOTTO study).

Salvage immunochemotherapy and transplant consolidation is the standard treatment for relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL). We tested a combination of Obinutuzumab and DHAP for treating R/R DLBCL. The primary end point was the rate of complete metabolic response (CMR). Secondary end points were stem cell mobilization, stem cell engraftment, overall survival, and feasibility. In this prospective, phase-2, single-arm trial (EudraCT 2014-004014-17) patients received the standard three doses of Obinutuzumab for the first cycle, and then one dose. Patients with CMR were consolidated with an autologous stem cell transplantation (ASCT). An interim analysis was provided after the first 29 patients to confirm the initial null hypothesis that at least 10/29 patients would achieve CMR. Among the 29 patients evaluated for the first stage only six patients (6/29, 21%) achieved CMR, thus, study enrollment was stopped. Nine patients exhibited extra-hematologic toxicities ≥ grade 3. Among the 19 patients that started stem cell mobilization, one failed (5%) and 18 achieved mobilization (95%). Of these 18 patients, nine were reinfused. Mobilization was observed in 16 patients (89%) after one or two apheresis rounds. The mean number of CD34 + cells mobilized was 5.8 × 106 /Kg (median: 5.5, IQR: 5-6.75). The mean number of reinfused CD34 + cells in the nine patients was 4.1 × 106 /Kg (median: 4.1, IQR: 3.5-5). Obinutuzumab combined with DHAP did not compromise stem cell mobilization or engraftment after ASCT in patients with DLBCL. However, Obinutuzumab + DHAP provided a lower CMR rate than expected.

Prevalence and determinants of serum antibodies to SARS-CoV-2 in the general population of the Gardena valley.

Estimating the spread of SARS-CoV-2 infection in communities is critical. We surveyed 2244 stratified random sample community members of the Gardena valley, a winter touristic area, amidst the first expansion phase of the COVID-19 pandemic in Europe. We measured agreement between Diasorin and Abbott serum bioassay outputs and the Abbott optimal discriminant threshold of serum neutralisation titres with recursive receiver operating characteristic curve. We analytically adjusted serum antibody tests for unbiased seroprevalence estimate and analysed the determinants of infection with non-response weighted multiple logistic regression. SARS-CoV-2 seroprevalence was 26.9% (95% CI 25.2-28.6) by June 2020. The bioassays had a modest agreement with each other. At a lower threshold than the manufacturer's recommended level, the Abbott assay reflected greater discrimination of serum neutralisation capacity. Seropositivity was associated with place and economic activity, not with sex or age. Symptoms like fever and weakness were age-dependent. SARS-CoV-2 mitigation strategies should account for context in high prevalence areas.

ABVD vs BEACOPP escalated in advanced-stage Hodgkin's lymphoma: Results from a multicenter European study.

The optimal first-line treatment for advanced-stage Hodgkin's lymphoma (HL) is still a matter of debate. While ABVD is less toxic and as effective as other, more intensive chemotherapy regimens, escalated BEACOPP (BEACOPPesc) is superior to ABVD for initial disease control and prolonged time-to-relapse. However, this advantage is associated with higher rate of early and late toxicities. As most of these data have been accumulated from clinical trials, a retrospective analysis was conducted in a large database of patients treated outside clinical trials to investigate the advantages and disadvantages of these regimes in a real-world setting. From October 2009 to October 2018, 397 advanced-stage HL patients treated with either ABVD or BEACOPPesc were retrospectively assessed in 7 European cancer centers (2 Austrian and 5 Italian centers). Complete metabolic remission (CMR) by PET was achieved in 76% and 85% of patients in the ABVD and BEACOPPesc groups, respectively (p = .01). Severe adverse events occurred more frequently with BEACOPPesc than ABVD. At a median follow-up of 8 years, 9% of the patients who achieved CMR after BEACOPPesc relapsed compared to 16.6% in the ABVD group (p = .043). No statistical difference in progression free survival (PFS) was observed between the two cohorts overall (p = .11), but there was a trend towards a superior PFS in high-risk patients treated with BEACOPPesc (p = .074). Nevertheless, overall survival was similar between the two groups (p = .94). In conclusion, we confirm that ABVD is an effective and less toxic therapeutic option for advanced-stage HL. Although BEACOPP results in better initial tumor control, the long-term outcome remains similar between the two regimens.

Frontline treatment of diffuse large B-cell lymphoma: Beyond R-CHOP.

Although the majority of patients with diffuse large B-cell lymphoma (DLBCL) can be cured with the standard immunochemotherapy R-CHOP, one-third of them relapses with a dismal outcome in most cases. In the recent years, remarkable advances have been achieved based on the discovery of molecular genetics in DLBCL. In addition to the major cell-of-origin designations of germinal center B-cell and activated B-cell subtypes, next-generation sequencing has unveiled the remarkable complexity of DLBCL and identified potential molecular targets for tailored therapies. Despite these findings, the current standard of care for DLBCL patients is still R-CHOP, and optimization of frontline therapy remains an important goal. In this review, we summarize recent updates on the evolution of frontline therapies for DLBCL.

Bendamustine plus Rituximab Versus R-CHOP as First-Line Treatment for Patients with Follicular Lymphoma Grade 3A: Evidence from a Multicenter, Retrospective Study.

BACKGROUND: Rituximab plus bendamustine (R-B) has been demonstrated to improve outcomes and reduce toxicity compared with rituximab, cyclophosphamide, doxorubicin, and prednisone (R-CHOP) in follicular lymphoma (FL). Nevertheless, in clinical practice, many centers still prefer R-CHOP to R-B in patients with FL grade 3A (FL3A). Therefore, we retrospectively assessed patients with FL3A treated with either R-CHOP or R-B in five European cancer centers and compared their outcomes. MATERIALS AND METHODS: We retrospectively assessed 132 patients affected by FL grade 3A treated with either R-B or R-CHOP in the first line and evaluated outcome and toxicity according to the type of treatment. This study included 101 patients who were a subgroup of a previously published cohort. RESULTS: R-B was less toxic and achieved a similar percentage of complete remissions compared with R-CHOP (97% vs. 96%, p = .3). During follow-up, 10 (16%) patients relapsed after R-B and 29 (41%) after R-CHOP (p = .001), leading to a median progression-free survival (PFS) of 15 versus 11.7 years, respectively (p = .03). Furthermore, R-B overcame the negative prognostic impact of BCL2 expression (15 vs. 4.8 years; p = .001). However, median overall survival was similar between both groups (not reached for both; p = .8). CONCLUSION: R-B as a first-line treatment of FL3A is better tolerated than R-CHOP and seems to induce more profound responses, leading to a significantly lower relapse rate and prolonged PFS. Therefore, R-B is a valid treatment option for FL grade 3A. IMPLICATIONS FOR PRACTICE: Rituximab plus bendamustine (R-B) has shown to be less toxic and more effective than rituximab, cyclophosphamide, doxorubicin, and prednisone (R-CHOP) in follicular lymphoma grade 3A. Although both regimens can induce a complete remission in >95% of patients, relapses occur more frequently after R-CHOP than R-B, leading to a significantly longer progression-free survival in the latter. R-B is also able to overcome the impact of negative prognosticators, such as BCL2 expression. However, because of the indolent course of this disease and efficient salvage treatments, overall survival was similar in both treatment groups. Therefore, R-B is a valid treatment option in this patient setting.

Evaluation of the Implementation of the Trauma Triage and Destination Plan on the Field Triage of Injured Patients in North Carolina.

OBJECTIVE: Timely triage and appropriate destination decision making for injured patients are central challenges faced by emergency medical services (EMS) systems. In 2010, North Carolina (NC) adopted a statewide Trauma Triage and Destination Plan (TTDP) based on the CDC's Field Triage Guidelines to better address these challenges. We sought to characterize the implementation of these guidelines by quantifying their effect on multiple metrics of patient care. METHODS: We employed a retrospective pre-post study design utilizing a statewide EMS medical record database. We assessed several metrics of patient care-including changes in destination choice, appropriateness of EMS destination, transit time to first hospital, transit time to definitive care, and others-in a six-month period in the year before and after the implementation of the guidelines. RESULTS: We evaluated a total of 190,307 EMS encounters pre- (n = 93,927) and post-implementation (n = 96,380). Among all patients, there was not a significant difference in the percentage transported to a community hospital or Level I, II, or III trauma center as their first destination. Among those patients meeting TTDP guidelines for transport to a trauma center, the number transported to a Level I or II trauma center decreased 1.0% from 30.6% (n = 2,911) to 29.6% (n = 2,954) (95% CI: -0.2%, 2.2%). Those transported to a Level I trauma center decreased 0.4% from 21.2% to 20.8% in the post-period (95% CI: -0.7%, 1.5%). There were also no significant changes in EMS scene times (14.0 pre-, 14.1 post-) and transport times (12.9 pre-, 13.0 post-). While scene distance from a Level I trauma center showed a decreased likelihood of transport to that center, there was an overall post-implementation increase of 2.5% from 18.0% to 20.5% (95% CI: -3.6%, -1.3%) in transport to a Level I trauma center among patients meeting anatomic criteria across all distance ranges. CONCLUSIONS: We found that implementation of region-specific destination plans based on the Field Triage Guidelines had little effect on selected hospital destination, scene times, transport times, and other metrics of EMS decision making and effectiveness. We suspect this is due to delays in information dissemination and adoption by field providers.

Lenalidomide in Relapsed or Refractory Diffuse Large B-Cell Lymphoma: Is It a Valid Treatment Option?

BACKGROUND: Despite the advent of new treatment strategies, many patients with diffuse large B-cell lymphoma (DLBCL) relapse or die of the disease. Prospective clinical trials have demonstrated that lenalidomide is an effective and safe treatment option, especially for non-germinal center B-cell (non-GCB) DLBCL. However, routine clinical data are lacking, which is why we provide the results of the so-far largest relapsed/refractory (R/R) DLBCL real-life analysis. METHODS: We retrospectively assessed 123 R/R DLBCL patients who received either 15 or 25 mg/day of lenalidomide from January 2006 to January 2015. RESULTS: During a median follow-up period of 4.5 years, complete remission was achieved in 32% and a partial remission in 33% non-GCB patients compared with 0% and 3% in the GCB group (p < .001 and .001, respectively), with median response durations of 15 and 5 months, respectively (p < .001). Lenalidomide at 25 mg was superior to 15 mg in terms of response (complete remission 21% and partial remission 23% vs. 0% and 8%; p = .007 and .05) and median response duration (10 vs. 4 months; p = .03). Toxicity was limited and reversible. Median progression-free survival differed between non-GCB and GCB patients (37 vs. 30 months; p < .001) and between the two dosages (24 vs. 34 months; p = .002). However, overall survival was similar between the subgroups (38-42 months). CONCLUSION: We provide evidence that lenalidomide is a valid treatment option for R/R DLBCL, with limited and reversible toxicity, and is more efficient in non-GCB DLBCL and at higher doses. IMPLICATIONS FOR PRACTICE: Despite the advent of new treatment strategies, many patients with diffuse large B-cell lymphoma (DLBCL) relapse or die of the disease; hence, novel therapeutic approaches are urgently needed. This study confirms that lenalidomide is a valid and well-tolerated treatment option for relapsed/refractory (R/R) DLBCL. Superior outcomes were observed in non-germinal center B-cell (GCB) DLBCL, probably because of inhibition of the nuclear factor-κB pathway. Similarly, high drug doses resulted in greater clinical benefits. Overall, lenalidomide is a suitable therapeutic option for R/R DLBCL, especially in non-GCB DLBCL, and 25 mg/day dosing should be preferred.

Bendamustine plus rituximab versus R-CHOP as first-line treatment for patients with indolent non-Hodgkin's lymphoma: evidence from a multicenter, retrospective study.

The optimal first-line treatment for advanced low-grade non-Hodgkin lymphomas (LG-NHL) is still highly debated. Recently, the StiL and the BRIGHT trials showed that the combination of rituximab and bendamustine (R-B) is non-inferior to rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) with a better toxicity profile. Utilizing a retrospective analysis, we compared the efficacy and safety of both regimens in clinical practice. From November 1995 to January 2014, 263 LG-NHL patients treated with either R-B or R-CHOP were retrospectively assessed in seven European cancer centers. Ninety patients were treated with R-B and 173 with R-CHOP. Overall response rate was 94 and 92 % for the R-B and the R-CHOP group, respectively. The percentage of complete response was similar for both groups (63 vs. 66 % with R-B and R-CHOP, respectively; p = 0.8). R-B was better tolerated and less toxic than R-CHOP. The median follow-up was 6.8 and 5.9 years for the R-CHOP and the R-B group, respectively. Overall, no difference in progression-free survival (PFS) (108 vs. 110 months; p = 0.1) was observed in the R-B group compared to the R-CHOP cohort. Nevertheless, R-B significantly prolonged PFS in FL patients (152 and 132 months in the R-B and R-CHOP group, respectively; p = 0.05). However, this result was not verified in multivariate analysis probably due to the limits of the present study. We confirm that the R-B regimen administered in patients with LG-NHL is an effective and less toxic therapeutic option than R-CHOP in clinical practice.

Extranodal Marginal Zone Lymphoma of Mucosa-Associated Lymphoid Tissue of the Salivary Glands: A Multicenter, International Experience of 248 Patients (IELSG 41).

BACKGROUND: The salivary gland is one of the most common sites involved by nongastric, extranodal marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT). A large series of patients with long-term follow-up has not been documented. This multicenter, international study sought to characterize the clinical characteristics, treatment, and natural history of salivary gland MALT lymphoma. METHODS: Patients with biopsy-confirmed salivary gland MALT lymphoma were identified from multiple international sites. Risk factors, treatment, and long-term outcomes were evaluated. RESULTS: A total of 247 patients were evaluated; 76% presented with limited-stage disease. There was a history of autoimmune disorder in 41%, with Sjögren disease being the most common (83%). Fifty-seven percent of patients were initially treated with local therapy with surgery, radiation, or both; 37 of patients were treated with systemic therapy initially, with 47% of those receiving rituximab; and 6% of patients were observed. The median overall survival (OS) was 18.3 years. The median progression-free survival (PFS) following primary therapy was 9.3 years. There was no difference in the outcomes between patients receiving local or systemic therapy in first-line management. On multivariate analysis, age <60 years and low to intermediate international prognostic index were associated with improved OS and PFS; Sjögren disease was associated with improved OS. CONCLUSION: Salivary gland MALT lymphoma has an excellent prognosis regardless of initial treatment, and patients with Sjögren disease have improved survival. Risks for long-term complications must be weighed when determining initial therapy.

Non-pegylated liposomal doxorubicin in lymphoma: patterns of toxicity and outcome in a large observational trial.

The anthracycline doxorubicin plays a major role in the treatment of lymphoproliferative disorders. However, its use is often limited due to cardiac toxicity, which seems to be much less in the liposomal non-pegylated formulation (Myocet®). The aim of this study was the evaluation of efficacy and toxicity of Myocet®-containing treatment regimens, with a focus on cardiotoxicity during treatment in lymphoma patients. A total of 326 consecutive patients, treated between March 2008 and December 2013 in 11 Austrian and 1 Italian cancer centers, were retrospectively assessed. Patients' baseline and treatment-related parameters were obtained by reviewing hospital records. Median age was 74 years (range 26-93). The most common histology was DLBCL (60 %), followed by FL (13 %) and MCL (8 %). At least one cardiovascular comorbidity was present in 72 % of patients. Most common grade 3/4 toxicities were hematologic, namely, leukopenia, neutropenia, thrombocytopenia, and febrile neutropenia in 44, 40, 17, and 16 %. Overall, 43 patients suffered a cardiac event (any grade) with most patients developing congestive heart failure. Parameters significantly associated with severe cardiac events (grades 3-5) were the presence of cardiovascular comorbidities, chronic obstructive pulmonary disease, and elevated baseline NT-proBNP. Treatment response after first line Myocet®-containing therapy was ≥58 % among all entities (range 58-86 %) and therefore comparable to those of conventional therapeutic regimens. Herein, we provide a detailed toxicity profile of Myocet®-containing chemotherapy regimens. Despite the high rate of patients with preexisting comorbidities, the number of adverse events was encouraging. However, these results need to be confirmed in a prospective randomized trial.

Cancer cachexia syndrome: pathogenesis, diagnosis, and new therapeutic options.

Cancer anorexia-cachexia syndrome (CACS) is the most frequent paraneoplastic syndrome occurring in half of all oncologic patients and is considered as a poor prognosticator. Patients usually present with weight loss, lipolysis, muscle wasting, anorexia, chronic nausea, inflammation, and asthenia. The etiopathogenesis of CACS is still poorly understood, although several factors and biological pathways are known to be involved. Because of the complexity of this multifactorial condition, a single agent therapy may not be sufficient. Indeed, there is a tendency toward an integrated multiple approach including nonpharmacological and pharmacological treatments. However, despite encouraging preliminary results, currently there is not enough evidence to support a change in clinical practice. This review provides a brief and practical summary of the diagnosis, pathogenesis, and treatment of CACS. Future perspectives will also be discussed.

B cell lymphoma with lung involvement: what is it about?

Primary lymphoma of the lung or pleural is a very rare condition. Due to the outdated literature data, the approximate occurrence of primary and secondary lung and/or pleural involvement according to the most common B cell lymphoma entities is unknown. To answer this open question in Austria, we screened the Tyrolean registry for B cell non-Hodgkin's lymphomas regarding primary and secondary lung involvement. Of 854 patients affected by B cell lymphoma, 7.5% had lung/pleural disease. This organ was the primary site in only 0.7%, while a secondary involvement was registered in 6.8%. Most of them were affected by diffuse large B cell lymphoma (DLBCL; 29/368, 8%) followed by follicular lymphoma (7/188, 4%), mantle cell lymphoma (7/57, 12%), mucosa-associated tissue lymphoma (10/37, 27%), posttransplant lymphoproliferative disease (6/24, 25%), Burkitt lymphoma (3/19, 16%), other lymphomas (1/32, 3%) and Richter transformation (1/11, 9%). Moreover, primary lung/pleural lymphoma is one of the rarest neoplasias affecting the lung, accounting for only 0.4% of cases. Lung/pleural involvement is a very rare condition among B cell lymphomas since it mainly occurs in the setting of a generalized disease. A large majority of patients with secondary organ involvement are affected by DLBCL and have similar clinical features at diagnosis to others with advanced-stage disease.
