Diffuse Large B-Cell Lymphoma With Cardiac Invasion Presented as Acute Myocardial Infarction and Left Ventricular Hypertrophy: A Case Report.

Primary cardiac lymphoma is an exceedingly rare malignant tumor, with diffuse large B-cell lymphoma (DLBCL) being the most prevalent histological subtype. This disease has non-specific clinical manifestations, making early diagnosis crucial. However, DLBCL diagnosis is commonly delayed, and its prognosis is typically poor. Herein, we report the case of a 51-year-old male patient with DLBCL who presented with recurrent chest tightness for 4 months as the primary clinical symptom. The patient was admitted to the hospital and diagnosed with acute myocardial infarction and left ventricular hypertrophy with heart failure. Echocardiography revealed a progression from left ventricular thickening to local pericardial thickening and adhesion in the inferior and lateral walls of the left ventricle. Finally, pathological analysis of myocardial biopsy confirmed the diagnosis of DLBCL. After treatment with the R-CHOP chemotherapy regimen, the patient's chest tightness improved, and he was discharged. After 2 months, the patient succumbed to death owing to sudden ventricular tachycardia, ventricular fibrillation, and decreased blood pressure despite rescue efforts. Transthoracic echocardiography is inevitable for the early diagnosis of DLBCL, as it can narrow the differential and guide further investigations and interventions, thereby improving the survival of these patients.

Efficacy and safety of netupitant/palonosetron in preventing nausea and vomiting in diffuse large B cell lymphoma patients undergoing R-CHOP chemotherapy.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma, for which cyclophosphamide, doxorubicin, vincristine, and prednisone with rituximab(R-CHOP) is one of the standard regimens. Given that R-CHOP is highly emetogenic, chemotherapy-induced nausea and vomiting (CINV) prevention is clinically important. However, there is a paucity of studies focusing on these patients. This study aimed to ascertain the effectiveness of an oral fixed-dose combination of netupitant and palonosetron (NEPA) in preventing CINV in patients with DLBCL undergoing first-line R-CHOP chemotherapy. Seventy patients were enrolled in this single-center prospective non-comparative study conducted between November 2020 and May 2023 in South Korea. NEPA was administered 1 h prior to chemotherapy initiation on day 1. The primary endpoint of the study was the complete response rate (no emesis, and no rescue medication) during the acute, delayed, and overall phases, which were assessed over a period of 120 h post-chemotherapy. The complete response rates for NEPA were 90.0% [95% CI 80.5, 95.9] for the acute phase, 85.7% [95% CI 75.3, 92.9] for the delayed phase, and 84.3% [95% CI 73.6, 91.9] for the overall phase, with no-emesis rates (acute: 97.1% [95% CI 97.1, 99.7], delayed: 95.7% [95% CI 88.0, 99.1], overall: 92.9% [95% CI 84.1, 97.6]). NEPA was well tolerated with no severe treatment-emergent adverse events. NEPA exhibited substantial efficacy in mitigating CINV in DLBCL patients undergoing R-CHOP chemotherapy, demonstrating high CR and no-emesis rates, and favorable safety profiles.

Change of hand sensation and function in patients with malignant lymphoma during early-stage vincristine chemotherapy: A single-center observational study.

This study aimed to investigate changes in hand sensation (finger tactile threshold and two-point discrimination) and function in patients with malignant lymphoma, particularly during the early stages of chemotherapy with vincristine. Eighteen patients with malignant lymphoma were enrolled in this study. Data on the Common Terminology Criteria for Adverse Events Version 4.0, the visual analog scale for hand numbness, the Semmes Weinstein monofilament test, static and moving two-point discrimination (2PD), grip strength, pinch strength, and the Purdue Pegboard test were collected at 3 time points: before the start of chemotherapy (T0), after the first cycle of chemotherapy (T1), and after the second cycle of chemotherapy (T2). No significant changes were observed in Semmes Weinstein monofilament test at T0, T1, or T2 in either hand. However, the static 2PD was significantly worse for the right ring, little, and left middle fingers, whereas the moving 2PD was significantly worse for the right ring, left index, middle, and ring fingers. Furthermore, the visual analog scale scores for hand numbness and left-hand grip strength worsened significantly. Right-hand grip strength, pinch strength of both hands, and Purdue Pegboard test showed no significant deterioration. Chemotherapy with vincristine may affect hand sensation and function in patients with malignant lymphoma by exacerbating finger 2PD and hand numbness. Additionally, during the early stages of vincristine chemotherapy, it is important to monitor for a decrease in grip strength specifically in the left hand.

A nationwide phase II study of delayed local treatment for children with high-risk neuroblastoma: The Japan Children's Cancer Group Neuroblastoma Committee Trial JN-H-11.

PURPOSE: Survival rates of patients with high-risk neuroblastoma are unacceptable. A time-intensified treatment strategy with delayed local treatment to control systemic diseases has been developed in Japan. We conducted a nationwide, prospective, single-arm clinical trial with delayed local treatment. This study evaluated the safety and efficacy of delayed surgery to increase treatment intensity. PATIENTS AND METHODS: Seventy-five patients with high-risk neuroblastoma were enrolled in this study between May 2011 and September 2015. Delayed local treatment consisted of five courses of induction chemotherapy (cisplatin, pirarubicin, vincristine, and cyclophosphamide) and myeloablative high-dose chemotherapy (melphalan, etoposide, and carboplatin), followed by local tumor extirpation with surgery and irradiation. The primary endpoint was progression-free survival (PFS). The secondary endpoints were overall survival (OS), response rate, adverse events, and surgical complications. RESULTS: Seventy-five patients were enrolled, and 64 were evaluable (stage 3, n = 8; stage 4, n = 56). The estimated 3-year PFS and OS rates (95% confidence interval [CI]) were 44.4% [31.8%-56.3%] and 80.7% [68.5%-88.5%], resspectively. The response rate of INRC after completion of the treatment protocol was 66% (42/64; 95% CI: 53%-77%; 23 CR [complete response], 10 VGPR [very good partial response], and nine PR [partial response]). None of the patients died during the protocol treatment or within 30 days of completion. Grade 4 adverse effects, excluding hematological adverse effects, occurred in 48% of patients [31/64; 95% CI: 36%-61%]. Major Surgical complications were observed in 25% of patients [13/51; 95% CI: 14%-40%]. CONCLUSION: This study indicates that delayed local treatment is feasible and shows promising efficacy, suggesting that this treatment should be considered further in a comparative study of high-risk neuroblastoma.

Evaluation of a multiagent chemotherapy protocol combining vincristine, cyclophosphamide, mitoxantrone and prednisolone (CMOP) for treatment of feline intermediate-large cell lymphoma.

OBJECTIVES: The aim of this study was to determine response rates, median progression-free intervals (PFIs) and median survival times (MSTs) for cats with intermediate-large cell lymphoma treated with a vincristine, cyclophosphamide, mitoxantrone and prednisolone (CMOP) protocol. A secondary objective was to determine the tolerability of mitoxantrone used within this multiagent protocol. METHODS: The medical records of 31 cats treated at a single institution between 2009 and 2022 were reviewed to identify suitable cases. Cats were included in the study if they had a confirmed diagnosis of intermediate-large cell lymphoma, had received a CMOP protocol as first-line treatment and had completed at least one 4-week cycle of this protocol. Modifications allowed in the protocol included the use of l-asparaginase, vinblastine substitution for vincristine, chlorambucil substitution for cyclophosphamide and dexamethasone or methylprednisolone substitution for prednisolone. RESULTS: The overall response rate was 74% (n = 23), with 45% (n = 14) achieving complete remission (CR), 29% (n = 9) achieving partial remission (PR) and 26% (n = 8) achieving stable disease (SD). The Kaplan-Meier median PFI and MST were 139 days and 206 days, respectively. Responders (CR or PR) had a significantly longer (P <0.001) median PFI and MST compared with non-responders (SD) (176 days vs 62 days, and 251 days vs 61 days, respectively). Cats that achieved CR had a significantly longer median PFI and MST (P <0.001) at 178 days and 1176 days, respectively. The 6-month and 1- and 2-year survival rates in cats with CR were 64%, 57% and 35%, respectively. Treatment with mitoxantrone was generally well tolerated, with no cats experiencing Veterinary Cooperative Oncology Group adverse effects above grade 2. CONCLUSIONS AND RELEVANCE: The CMOP protocol is an alternative and well-tolerated treatment for cats with intermediate-large cell lymphoma. As demonstrated with previous chemotherapy protocols, cats that respond to treatment, particularly those that achieve CR, are likely to have more durable responses.

Vincristine-induced adverse events related to body weight in dogs treated for lymphoma.

BACKGROUND: Traditional dosing of chemotherapy drugs based on body surface area may overdose small dogs, leading to an increased frequency of adverse events (AEs). HYPOTHESIS/OBJECTIVES: Evaluate the frequency of hematologic and gastrointestinal AEs in dogs with newly diagnosed lymphoma treated with vincristine weighing ≤15 kg in comparison to dogs weighing >15 kg. We hypothesized that dogs weighing ≤15 kg would experience a higher frequency of AEs. ANIMALS: One hundred and thirty-eight dogs with newly diagnosed lymphoma were treated with vincristine. METHODS: A multicenter retrospective study reviewing hematologic data and medical record information. Complete blood counts were performed no more than 24 hours before vincristine administration and then between 4 and 8 days post-administration. Data were evaluated using logistic regression or ordinal logistic regression. RESULTS: Thirty-eight dogs weighing ≤15 kg and 100 dogs weighing >15 kg were included. The median vincristine dose for both groups was 0.6 mg/m2. Seventeen (12.3%) instances of neutropenia occurred with no significant difference in overall frequency or grade between groups. Thirty initially asymptomatic substage A dogs (29.4%) experienced gastrointestinal AEs. Because of the widespread use of gastrointestinal supportive care medications, statistical comparison between groups could not be performed. Seven instances of hospitalization occurred (5.0%) and the risk of hospitalization did not differ significantly between groups (P = .37). CONCLUSIONS AND CLINICAL IMPORTANCE: Vincristine dosed at ≤0.6 mg/m2 does not increase the risk of hematologic AEs in dogs weighing ≤15 kg.

Real-life study on the use of response adapted therapy in patients with Hodgkin Lymphoma: Results from a multicenter experience.

Few data are known regarding the use of interim positron emission tomography (iPET) after the first two cycles (iPET2) of chemotherapy in treatment-naïve classical Hodgkin lymphoma (cHL) in routine clinical practice, and about the real-life adoption of intensification strategies for iPET positive patients. We conducted a multicenter retrospective study on cHL to investigate the use of iPET in the real-life setting, its prognostic role and outcomes of patients early shifted to intensification. Six hundreds and forty-one patients were enrolled (62% had advanced stage). iPET2 was positive in 89 patients (14%) including 8.7% and 17% early and advanced stage patients, respectively (p = 0.003). Among iPET 2 positive cases treatment was immediately modified in 19 cases; in 14 cases treatment was modified after an additional positive iPET4. Overall 56 iPET2 positive patients never received intensified therapies. Most frequently used intensified therapy was autologous stem cell transplantation followed by BEACOPP. After a median follow-up of 72 months, the 5-year progression-free survival (PFS) was 82% with iPET2 positive patients showing a worse PFS compared with iPET2 negative cases: 31% versus 85%. Focusing on advanced stage patients with a positive iPET2, the 5-year PFS was 59% for patients shifted to intensified therapy at any time point versus 61% for patients who never received intensified therapy. Our study confirmed the higher curability of naïve cHL patients in a real-world setting, and the prognostic role of iPET2 in this setting. A poor adherence to response-adapted strategy which however did not translate into a difference in patient outcomes.

Treatment patterns, clinical outcomes and gene mutation characteristics of hepatitis B virus-associated mantle cell lymphoma.

Mantle cell lymphoma (MCL) is an uncommon and incurable B-cell lymphoma subtype that has an aggressive course. Hepatitis B virus (HBV) infection has been associated with an increased risk for B-cell lymphomas, and is characterized by distinct clinical and genetic features. Here, we showed that 9.5% of MCL Chinese patients were hepatitis B surface antigen positive (HBsAg+). Compared to HBsAg-negative (HBsAg-) patients, HBsAg+ MCL patients had a greater incidence of elevated lactate dehydrogenase (LDH), but no difference was observed in the other clinical characteristics, including sex, age, ECOG ps, Ann Arbor stage, MIPI, extranodal involvement and Ki-67. The HD-AraC (high-dose cytarabine) regimen was the main first-line induction regimen for younger HBsAg+ patients, and cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) were used for elderly patients. HBsAg seropositivity was associated with a significantly shorter PFS than HBsAg seronegativity when patients were treated with rituximab or CHOP-based regimens. Compared with CHOP, the HD-AraC regimen was associated with longer PFS in HBsAg+ patients. Treatment with a Bruton tyrosine kinase inhibitor (BTKi) alone can also cause HBV reactivation. Among the 74 patients who underwent targeted deep sequencing (TDS), the nonsynonymous mutation load of HBsAg+ MCL patients was greater than that of HBsAg- MCL patients. HDAC1, TRAF5, FGFR4, SMAD2, JAK3, SMC1A, ZAP70, BLM, CDK12, PLCG2, SMO, TP63, NF1, PTPR, EPHA2, RPTOR and FIP1L1 were significantly enriched in HBsAg+ MCL patients.

Modified R-BAC plus BTK inhibitor regimen in newly diagnosed young patients with mantle cell lymphoma: a real-world retrospective study.

To explore the optimal treatment for young patients with untreated mantle cell lymphoma (MCL), we compared the efficacy and safety of R-CHOP/R-DHAP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone/rituximab, dexamethasone, cytarabine and cisplatin) and R-BAP (rituximab, bendamustine, cytarabine, and prednisone) plus BTK (Bruton's tyrosine kinase) inhibitors in newly diagnosed patients. Eighty-three young patients (≤ 65 years old) with newly diagnosed MCL admitted to the First Affiliated Hospital of Zhengzhou University from January 1, 2014, to June 1, 2023, using R-CHOP/R-DHAP or R-BAP plus BTK inhibitor were assessed in this study. The median age at presentation was 60 (42-65) years in 83 patients, including 64 males and 19 females; 59 were treated with R-CHOP/R-DHAP regimen chemotherapy, and 24 were treated with R-BAP in combination with the BTK inhibitor regimen. The median follow-up was 17 months (2-86 months) in 83 patients, and the median PFS (progression-free survival) time was not reached. The CRR (complete response rate) of the R-BAP group was higher than that of the R-CHOP/R-DHAP group (87.5% vs. 54.2%, P = 0.005). The ORR (overall response rate) was not significantly different between the two groups (ORR: 91.7% vs. 84.7%, P = 0.497). The PFS (progression-free survival) of the R-BAP group was longer than that of the R-CHOP/R-DHAP group (P = 0.013), whereas OS was not significantly different between the two groups (P = 0.499). The most common adverse effect in both groups was hematotoxicity, with a higher incidence of grade 3-4 lymphopenia and grade 3-4 thrombocytopenia in the R-BAP group than in the R-CHOP/R-DHAP group (P = 0.015 and P = 0.039). Male sex (HR = 4.257, P = 0.013), LDH (lactate dehydrogenase) ≥ 245 U/L (HR = 3.221, P = 0.012), pleomorphic-blastoid (HR = 2.802, P = 0.043) and R-CHOP/R-DHAP regimen (HR = 7.704, P = 0.047) were independent risk factors for PFS. Ki67 ≥ 30% (HR = 8.539, P = 0.005) was an independent risk factor for OS. First-line treatment with R-BAP in combination with BTK inhibitor improved CRR and prolonged PFS in young patients with mantle cell lymphoma and adverse events were tolerable.

Romidepsin Plus Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone Versus Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone in Patients With Previously Untreated Peripheral T-Cell Lymphoma: Final Analysis of the Ro-CHOP Trial.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.The primary analysis of the Ro-CHOP phase III randomized controlled trial (ClinicalTrials.gov identifier: NCT01796002) established that romidepsin (Ro) plus cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) did not yield an increased efficacy compared with CHOP alone as first-line treatment of peripheral T-cell lymphoma. We report the planned final analysis 5 years after the last patient enrolled. With a median follow-up of 6 years, median progression-free survival (PFS) was 12.0 months compared with 10.2 months (hazard ratio [HR], 0.79 [95% CI, 0.62 to 1.005]; P = .054), while median overall survival was 62.2 months (35.7-86.6 months) and 43.8 months (30.1-70.2 months; HR, 0.88 [95% CI, 0.68 to 1.14]; P = .324) in the Ro-CHOP and CHOP arms, respectively. In an exploratory analysis, the median PFS in the centrally reviewed follicular helper T-cell lymphoma subgroup was significantly longer in the Ro-CHOP arm (19.5 v 10.6 months, HR, 0.703 [95% CI, 0.502 to 0.985]; P = .039). Second-line treatments were given to 251 patients with a median PFS2 and OS2 after relapse or progression of 3.3 months and 11.5 months, respectively. Within the limits of highly heterogeneous second-line treatments, no specific regimen seemed to provide superior disease control. However, a potential benefit was observed with brentuximab vedotin in association with chemotherapy even after excluding anaplastic large-cell lymphoma subtype or after adjusting for histology and international prognostic index in a multivariate model (HR for PFS, 0.431 [95% CI, 0.238 to 0.779]; P = .005).

Secondary central nervous system involvement in patients with diffuse large B-cell lymphoma treated with rituximab combined CHOP therapy - a supplementary analysis of JCOG0601.

Secondary central nervous system involvement (sCNSi) in diffuse large B-cell lymphoma (DLBCL) is fatal. However, its features in patients with sCNSi who are categorized as lower risk by international prognostic index (IPI) or CNS-IPI are not yet fully understood. In the present analysis, we evaluated DLBCL patients who developed sCNSi at their first progression and who participated in JCOG0601, most of whom were lower risk by IPI. Of 409 patients, 21 (5.1%) developed sCNSi during a median follow-up of 4.9 years. Five-year cumulative incidence of sCNSi were 5.1%; and 4.0%, 5.3%, and 11.5% at low, intermediate, and high risk of CNS-IPI, respectively. The most common locations of extranodal lesions at the time of registration in patients with sCNSi were the stomach (n = 4), paranasal cavity (n = 3), and bone marrow (n = 2). In univariable analysis, paranasal cavity lesion was a high-risk factor for sCNSi (subdistribution hazard ratio, 4.34 [95% confidence interval 1.28-14.73]). Median overall survival after sCNSi was 1.3 years, with a 2-year overall survival rate of 39.3%. The incidence of sCNSi in DLBCL patients at lower risk of CNS-IPI was low, as previously reported, but paranasal cavity lesion might indicate high risk for organ involvement. CLINICAL TRIAL REGISTRATION: JCOG0601 was registered in the UMIN Clinical Trials Registry (UMIN000000929, date of registration; December 04, 2007) and the Japan Registry of Clinical Trials (jRCTs031180139, date of registration; February 20, 2019).

Clinicopathological features and prognosis of primary pulmonary rhabdomyosarcoma in middle-aged and elderly patients: a case report and literature review.

To date, only 34 cases of primary pulmonary rhabdomyosarcoma (PPRMS) in the middle-aged and elderly population have been published. However, analyses of the clinicopathological characteristics and prognosis of PPRMS in this population have not been performed. A 75-year-old man visited our hospital because of abdominal pain and discomfort. His serum lactate dehydrogenase, neuron specific enolase, and progastrin-releasing peptide levels were elevated. Positron emission tomography-computed tomography revealed a lobulated mass of 7.6 × 5.5 cm2 in the lower lobe of the left lung with abnormally high fluoro-2-deoxy-d-glucose metabolism. Histologically, the tumor cells were small with little cytoplasm, deep nuclear staining, and heavily stained nuclear chromatin. Immunohistochemically, the tumor cells were positive for desmin, MyoD1 myogenin, synaptophysin, and CD56. Cytogenetic analysis for FOXO1A translocation was negative. Finally, the patient was diagnosed with PPRMS. He received combined chemotherapy with vincristine 1 mg, actinomycin 0.4 mg, cyclophosphamide 0.8 mg; however, only one course of chemotherapy was completed, and the patient died 2 months after diagnosis. PPRMS in middle-aged and elderly people is a highly malignant soft tissue tumor with significant clinicopathological characteristics.

EMACO for treatment of gestational trophoblastic neoplasia: A multinational multicenter study.

OBJECTIVE: To investigate the efficacy and toxicity of etoposide, methotrexate, actinomycin D alternating with cyclophosphamide, and vincristine (EMACO) for treatment of gestational trophoblastic neoplasia, and for factors independently associated with EMACO resistance and disease-specific death in an international cohort. METHODS: Medical records of GTN patients who received EMACO during 1986-2019 from gestational trophoblastic disease centers from four countries including the USA, Thailand, Hungary, and Brazil, were retrospectively reviewed. Among 335 GTN patients, 266 patients who received EMACO as primary chemotherapy were included in the primary treatment group, and 69 patients who received EMACO after relapse/resistance to single-agent chemotherapy were included in the prior treatment group. RESULTS: Three-quarters (76.1%) of all patients achieved remission, and the survival rate was 89%. The prior treatment group had better outcomes than the primary treatment group relative to remission rate (87.0% vs. 73.3%, p = 0.014) and number of EMACO cycles to achieve remission (3 vs. 6 cycles, p < 0.001). Sustained remission increased to 87.2% in EMACO-resistant patients treated with later-line chemotherapy. Number of metastatic organs ≥2 (adjusted odds ratio [aOR]: 2.33, p = 0.049) was the only independent predictor of EMACO resistance among overall patients. Interval from index pregnancy ≥7 months (aOR: 4.34, p = 0.001), and pretreatment hCG >100,000 IU/L (aOR: 2.85, p = 0.028) were independent predictors of EMACO resistance in the high-risk subgroup. The only factor independently associated with disease-specific death was EMACO resistance (aOR: 176.04, p < 0.001). CONCLUSIONS: EMACO is an effective treatment for GTN. Number of metastatic organs and EMACO resistance were the independent predictors of EMACO resistance and disease-specific death, respectively.

NUT Carcinoma in Children and Adolescents: The Expert European Standard Clinical Practice Harmonized Recommendations.

BACKGROUND AND AIMS: Nuclear protein of the testis ( NUT ) carcinoma (NC) is a rare and highly aggressive tumor mainly occurring in adolescents and young adults, defined by the presence of a somatic NUTM1 rearrangement. The aim is to establish internationally harmonized consensus recommendations for the diagnosis and treatment of adolescents and young adults with NC in the framework of the European Reference Network for Paediatric Oncology. METHODS: The European Cooperative Study Group for Pediatric Rare Tumors developed recommendations according to the Consensus Conference Standard Operating procedure methodology and reviewed by external "experts." No evidence of level I to II exists. Recommendations were developed based on published prospective (level III), but more frequently retrospective series (level IV), case reports (level V), and personal expertise (level V). In addition, "strength" of recommendations were categorized by grading (grade A to E). RESULTS: Histology is mandatory for the diagnosis of NC, including immunolabeling with anti-NUT antibodies and molecular biology ( NUTM1 rearrangement) (level V; grade A). Treatment of NC usually combines aggressive approaches in multimodal regimens. Chemotherapy should be considered as first-line treatment (neoadjuvant vincristine-adriamycin-ifosfamide/cisplatin-adriamycin-ifsofamide or vincristine-doxorubicin-cyclophosphamide/ifosfamide-etoposide) for unresectable or metastatic tumor (ie, 3 courses), rapidly followed by local treatment (level IV; grade B). Referral to a specialized surgical oncology center is highly recommended (level V; grade A). In localized NC, a complete microscopic surgical resection should be attempted whenever and as soon as possible, followed by primary irradiation (60 to 70 Gy) and involved lymph nodes area (level IV; grade B). For head and neck tumors, a systematic neck dissection might be considered, even if N0 (level V; grade C). Adjuvant postirradiation chemotherapy is recommended, for a total of 9 to 12 courses (level IV; grade B). For first-line resected tumors, concomitant adjuvant chemotherapy to radiotherapy may be discussed (level IV; grade B). Targeted therapies and immunotherapeutic regimens should be delivered in the setting of prospective trials (level V; grade B). CONCLUSIONS: This project leads to a consensus strategy based on international experience with this very rare disease.

Rabdomiossarcoma de ovário em paciente jovem: Relato de caso / Ovarian rhabdomyosarcoma in a young patient: report of case

O sarcoma de partes moles mais comum na infância é o rabdomiossarcoma. Entretanto a localização ovariana é extremamente rara. Acredita-se que este tumor se origina de células imaturas destinadas a compor o músculo esquelético, porém pode surgir em locais onde tipicamente não há músculo esquelético. O diagnóstico do Rabdomiossarcoma primário de ovário pode causar um dilema entre os clínicos, cirurgiões e patologistas, por se tratar de um tumor muito raro. Após o diagnóstico, é necessária a investigação de possíveis metástases. Este caso trata de uma paciente de 17 anos, submetida a parto cesáreo e, no intraoperatório, foi observado aumento de volume, inespecífico, de ovário direito sendo optado por não abordar naquele momento. De antecedentes pessoais, apresentava ooforectomia esquerda aos 13 anos, por Tumor de células da granulosa juvenil e lobectomia inferior esquerda por malformação adenomatosa cística aos 7 anos. Deu entrada no Pronto Socorro 17 dias após dar à luz com queixa de febre, vômitos e dor abdominal. Foi realizada ultrassonografia de urgência, onde foi visualizada massa sólida em fossa ilíaca direita medindo 14,0 x 11,2 x 10,8 cm. Realizada laparotomia exploradora com anexectomia direita e cito-redução subótima do tumor. O resultado anátomo-patológico demonstrou neoplasia maligna fusocelular com áreas de necrose em ovário. A complementação com o estudo imunohistoquímico concluiu rabdomiossarcoma embrionário. Ela voltou a procurar atendimento no Pronto Socorro dois meses após a abordagem com queixa de vômitos biliosos e epigastralgia. Realizou tomografia computadorizada que identificou recidiva do tumor. Durante a internação, evoluiu com quadro de tromboembolismo pulmonar agudo. Diante disso, foi iniciada terapia com enoxaparina em dose plena e quimioterapia com esquema VAC (Vincristina, Doxorrubicina e Ciclofosfamida). Entretanto, ela apresentou insuficiência de múltiplos órgãos, que culminou com o óbito da paciente. O curso clínico desse caso mostra a rápida progressão e letalidade dessa neoplasia. Além da histopatologia, a idade, o tamanho do tumor, a ressecabilidade, o subtipo histopatológico, a presença de metástase no momento do diagnóstico e a invasão linfonodal influenciam no curso clínico da doença.

Brentuximab Vedotin with Chemotherapy in Pediatric High-Risk Hodgkin's Lymphoma.

BACKGROUND: In adults with advanced-stage Hodgkin's lymphoma, the CD30-directed antibody-drug conjugate brentuximab vedotin combined with multiagent chemotherapy has been shown to have greater efficacy, but also more toxic effects, than chemotherapy alone. The efficacy of this targeted therapy approach in children and adolescents with Hodgkin's lymphoma is unclear. METHODS: We conducted an open-label, multicenter, randomized, phase 3 trial involving patients 2 to 21 years of age with previously untreated Hodgkin's lymphoma of stage IIB with bulk tumor or stage IIIB, IVA, or IVB. Patients were assigned to receive five 21-day cycles of brentuximab vedotin with doxorubicin, vincristine, etoposide, prednisone, and cyclophosphamide (brentuximab vedotin group) or the standard pediatric regimen of doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (standard-care group). Slow-responding lesions, defined by a score of 4 or 5 (on a 5-point scale, with scores of 1 to 3 indicating rapid-responding lesions), were identified on centrally reviewed positron-emission tomography-computed tomography after two cycles. Involved-site radiation therapy was administered after the fifth cycle of therapy to slow-responding lesions and to large mediastinal adenopathy that was present at diagnosis. The primary end point was event-free survival, defined as the time until disease progression occurred, relapse occurred, a second malignant neoplasm developed, or the patient died. Safety and overall survival were assessed. RESULTS: Of 600 patients who were enrolled across 153 institutions, 587 were eligible. At a median follow-up of 42.1 months (range, 0.1 to 80.9), the 3-year event-free survival was 92.1% (95% confidence interval [CI], 88.4 to 94.7) in the brentuximab vedotin group, as compared with 82.5% (95% CI, 77.4 to 86.5) in the standard-care group (hazard ratio for event or death, 0.41; 95% CI, 0.25 to 0.67; P<0.001). The percentage of patients who received involved-site radiation therapy did not differ substantially between the brentuximab vedotin group and the standard-care group (53.4% and 56.8%, respectively). Toxic effects were similar in the two groups. Overall survival at 3 years was 99.3% (95% CI, 97.3 to 99.8) in the brentuximab vedotin group and 98.5% (95% CI, 96.0 to 99.4) in the standard-care group. CONCLUSIONS: The addition of brentuximab vedotin to standard chemotherapy resulted in superior efficacy, with a 59% lower risk of an event or death, and no increase in the incidence of toxic effects at 3 years.

Carfilzomibe no tratamento de pacientes com mieloma múltiplo recidivado ou refratário, que receberam terapia prévia / Carfilzomib in the treatment of patients with relapsed or refractory multiple myeloma who have received prior therapy

INTRODUÇÃO: O mieloma múltiplo (MM) é uma neoplasia hematológica maligna caracterizada pela proliferação descontrolada de plasmócitos alterados na medula óssea, resultando na produção aumentada de imunoglobulinas não funcional (proteína monoclonal). O acúmulo destas imunoglobulinas e a interação dos plasmócitos com outras células da medula óssea resultam em anemia, lesões ósseas, infecções, hipercalcemia, injúria renal, fadiga e dor. A incidência mundial informada pelo Globocan é de 2,2 novos casos por 100.000 habitantes em homens e 1,5/100.000 em mulheres, com ocorrência, a nível mundial, de 176 mil novos casos e 117 mil mortes em 2020. Carfilzomibe é um agente antineoplásico, inibidor de proteassoma que se liga seletiva e irreversivelmente nos sítios ativos. Tem atividade antiproliferativa e pró-apoptóticas. PERGUNTA DE PESQUISA: Kyprolis® (carfilzomibe) em combinação com dexametasona é eficaz e seguro no tratamento de pacientes com mieloma múltiplo recidivado ou refratário que receberam uma terapia prévia quando em comparação a bortezomibe, ciclofosfamida, dexametasona, cisplatina, doxorrubicina, doxorrubicina lipossomal, etoposídeo, melfalana, vincristina ou talidomida? EVIDÊNCIAS CLÍNICAS: O demandante realizou as buscas na literatura utilizando as seguintes bases de dados: The Cochrane Library, Medline via PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Centre for Reviews and Dissemination (CRD), o que resultou na inclusão de 14 publicações. Na análise conduzida pela Secretaria Executiva foram consideradas 12 publicações referentes a um ensaio clínico randomizado e uma publicação de revisão sistemática. O estudo ENDEAVOR foi um ensaio clínico de fase III, multicêntrico, aberto, que incluiu 929 participantes randomizados para receber carfilzomibe+dexametasona ou bortezomibe+dexametasona. A mediana de SLP foi 18,7 meses (IC 95%, 15,6 a não estimável) no grupo que recebeu carfilzomibe comparado a 9,4 meses (IC 95%, 8,4 a 10,4) no grupo que recebeu bortezomibe, resultando em uma magnitude de benefício absoluto de 9,3 meses (HR 0,53 [IC95% 0,44 a 0,65]; p< 0,0001). A duração mediana de resposta foi 21,3 meses (IC95% 21,3 a não estimável) no grupo carfilzomibe e 10,4 meses (IC95% 9,3 a 13,8) no grupo bortezomibe. Em ambos os grupos, 98% dos participantes apresentaram eventos adversos (qualquer grau), sendo a anemia (43% versus 28%), diarreia (36,7% versus 40,6%) e febre (32,6% versus 15,4%) os eventos mais frequentes nos grupos carfilzomibe e bortezomibe, respectivamente. Os eventos adversos mais comuns grau 3 ou maior foram reportados em 81,9% dos participantes do grupo carfilzomibe (n=379) e 71,1% no grupo bortezomibe (n=324), sendo a anemia (17,3% no grupo carfilzomibe e 10,1% no grupo bortezomibe), hipertensão (14,9% versus 3,3%), trombocitopenia (12,5% versus 14,7%),os três eventos mais frequentes. Insuficiência cardíaca grau 3 ou superior, foi mais frequente no grupo carfilzomibe (6%) que no grupo bortezomibe (2%.). AVALIAÇÃO ECONÔMICA: O demandante apresentou uma análise de custo-efetividade. Na análise do cenário base, em um horizonte temporal de 30 anos, carfilzomibe acrescentou ganhos incrementais de 1,19 QALY, resultando em uma razão de custo utilidade incremental (RCEI) de R$ 195.310,00 por QALY. No cenário proposto pela Secretária-Executiva (horizonte temporal de 10 anos e valor de utilidade derivada do estudo ENDEAVOR), carfilzomibe gerou benefício de 0,63 QALY, com RCEI de R$ 365.830,00 por QALY. ANÁLISE DE IMPACTO ORÇAMENTÁRIO: Com o desconto apresentado pelo demandante, a incorporação de carfilzomibe ao SUS implica em custos adicionais ao sistema de saúde no montante de aproximadamente R$ 365 milhões em cinco anos. A principal limitação da análise foi a estimativa da população. MONITORAMENTO DO HORIZONTE TECNOLÓGICO: Foram identificadas 10 tecnologias potenciais para compor o esquema terapêutico de pacientes adultos com mieloma múltiplo recidivado ou refratário: Belantamabe mafodotin, Ciltacabtageno autoleucel, Elranatamab, Iberdomida, Idecabtagene vicleucel, Isatuximabe, nivolumabe, selinexor, teclistamab, venetoclax. Tais medicamentos são anticorpo monoclonal ligado a um antineoplásico, anticorpo biespecífico, anticorpo monoclonal, imumodulador, terapias baseadas em células T autólogas geneticamente modificadas (CAR-T), inibidor SINE, ou inibidor de Bcl-2. A maioria não possui registro na FDA, EMA ou Anvisa. CONSIDERAÇÕES FINAIS: Os resultados sugerem eficácia e segurança do carfilzomibe na população elegível, porém, no horizonte temporal de 10 anos, com QALY < 1, RCEI de R$ 365.830,00 por QALY e impacto orçamentário de aproximadamente R$ 17 milhões no primeiro ano de incorporação e R$ 131 milhões no 5º ano da incorporação, totalizando R$ 365 milhões em cinco anos. RECOMENDAÇÃO PRELIMINAR DA CONITEC: Os membros do Plenário presentes na 109ª Reunião Ordinária da Conitec, realizada no dia 08 de junho de 2022, sem nenhuma declaração de conflito de interesse, deliberaram por unanimidade, encaminhar o tema para consulta pública com recomendação preliminar desfavorável à incorporação de carfilzomibe para o tratamento de mieloma múltiplo recidivado ou refratário no SUS. Os membros consideraram a evidência científica boa e favorável ao carfilzomibe, porém, a RCEI e o impacto orçamentário foram considerados muito altos para o tratamento de uma doença que já tem outras opções terapêuticas disponíveis no SUS. CONSULTA PÚBLICA: Entre os dias 08/07/2022 e 27/07/2022 foram recebidas 421 contribuições, sendo 152 pelo formulário para contribuições técnico-científicas e 269 pelo formulário para contribuições sobre experiência ou opinião de pacientes, familiares, amigos ou cuidadores de pacientes, profissionais de saúde ou pessoas interessadas no tema. A maioria foi a favor da incorporação de carfilzomibe no SUS (97% via formulário técnico-científico e 100%). O principal benefício apontado nas contribuições técnico-científicas foi sobre a eficácia, aumento da sobrevida e qualidade de vida, além da disponibilidade de mais uma opção terapêutica e promoção da igualdade no tratamento nos sistemas público e privado de saúde. A empresa detentora do registro do medicamento atualizou o preço do medicamento, e consequentemente os valores do impacto orçamentário e avaliação econômica. No impacto orçamentário o valor ficou em R$ 95,3 milhões em cinco anos. Nas contribuições de experiência e opinião, a totalidade dos respondentes discordou da recomendação preliminar da Conitec. No âmbito das opiniões e experiências positivas, foi mencionada a necessidade de garantir o acesso ao carfilzomibe, especialmente por representar uma alternativa para pacientes recidivados e refratários. Também foi citada a eficácia da tecnologia. Como dificuldades, destacou-se a falta de acesso pelo SUS. Em relação a outros medicamentos, foram mencionados benefícios, mas, também, a eficácia limitada no caso de pacientes recidivados. RECOMENDAÇÃO FINAL DA CONITEC: Os membros do Plenário da Conitec, em sua 112ª Reunião Ordinária, realizada no dia 31 de agosto de 2022, deliberaram por maioria simples, recomendar a não incorporação no SUS de carfilzomibe para o tratamento de pacientes com mieloma múltiplo recidivado ou refratário, que receberam terapia prévia, no SUS. Não houve apresentação de dados clínicos adicionais. Com o preço do medicamento atualizado, ainda assim não se mostrou custo-efetivo. Foi assinado o Registro de Deliberação nº 765/2022. DECISÃO: Não incorporar, no âmbito do Sistema Único de Saúde - SUS, o carfilzomibe para o tratamento de pacientes com mieloma múltiplo recidivado ou refratário, conforme a Portaria nº 107, publicada no Diário Oficial da União nº 184, seção 1, página 75, em 27 de setembro de 2022.

Efficacies of FAEV and EMA/CO regimens as primary treatment for gestational trophoblastic neoplasia.

BACKGROUND: Guidelines recommend etoposide, methotrexate, actinomycin D (EMA)/cyclophosphamide, vincristine (CO) as first-line treatment for high-risk gestational trophoblastic neoplasia (GTN). However, the floxuridine, actinomycin D, etoposide and vincristine (FAEV) regimen is commonly used to treat these patients in China. We conducted a randomised controlled trial to compare the efficacies and toxicities of FAEV and EMA/CO. METHODS: Ninety-four patients with GTN were enrolled between May 2015 and April 2019 and randomly assigned to the FAEV or EMA/CO regimen. The rates of complete remission and relapse and the toxicities were compared in August 2021. RESULTS: Five patients were excluded from the analysis. There were 46 patients in the FAEV group and 43 patients in the EMA/CO group. The complete remission rates following primary treatment were 89.1% and 79.1% (P = 0.193), respectively. The relapse rates were 8.7% and 9.3% (P = 0.604). The apparent incidences of grade 4 myelosuppression were 60.9% and 32.6% (P = 0.008), respectively; however, they became both 32.6% (P = 0.996) after granulocyte colony-stimulating factor support. Other adverse reactions were similar in the two groups. No patient died of disease. CONCLUSION: FAEV has comparable efficacy and toxicity to EMA/CO as the primary treatment for high-risk GTN, and may thus be another first-line choice of chemotherapy.

Extending Treatment Intervals of R-CHOP Therapy Might Be Acceptable for Some Patients with Non-indolent Non-Hodgkin's B-cell Lymphoma.

R-CHOP therapy is generally performed every 3 weeks. We investigated the effects of extending the interval of R-CHOP therapy for > 1 week on the prognoses of patients with non-indolent non-Hodgkin's B-cell lymphoma. Among the 338 patients with non-indolent non-Hodgkin's B-cell lymphoma who received initial chemotherapy at our institution, we focused on 178 patients who received R-CHOP therapy and analyzed the outcomes of the patients stratified by the treatment intervals. The estimated 3-year overall survival (OS) for the entire population was 82.1%. Patients treated at intervals of ≥ 4 weeks were significantly older, and they had significantly longer follow-up periods and lower relative dose intensity. But the estimated 3-year OS was comparable to those treated at <4 weeks (83.3% vs. 80.5% p=0.947). In a multivariate analysis, age and the dose of anti-cancer agents had significant impacts on OS, but there was no significant relationship regarding the treatment intervals. Propensity score matching confirmed the same result. R-CHOP therapy every around 4 weeks could achieve relatively good survival in some selected patients with non-indolent non-Hodgkin's B-cell lymphoma.

Follicular Lymphoma: a Focus on Current and Emerging Therapies

Follicular lymphoma (FL) is the most common indolent lymphoma and is characterized by a relapsing and remitting course. In addition to significant biologic heterogeneity, the clinical trajectory for patients is variable, with some being observed for many years, and others having aggressive disease requiring multiple treatment courses. Unfortunately, FL remains incurable, and continues to cause early mortality. Improved understanding of the genetic and immune biology of FL has led to several FDA-approved therapies in the relapsed and refractory setting, including PI3K inhibitors; immunomodulatory agents; the EZH2 inhibitor, tazemetostat; and anti-CD19 chimeric antigen receptor (CAR) T-cell therapy, axicabtagene ciloleucel. This review outlines the current approach to the diagnosis and treatment of FL with a focus on emerging investigational therapies, including targeted protein inhibitors, antibody-drug conjugates, monoclonal antibodies, bispecific antibodies, and novel combination strategies.
