RESUMEN
BACKGROUND: Primary testicular lymphoma (PTL) is relatively rare. The contralateral testis is a common site of PTL relapse; therefore, once complete remission is achieved, radiation therapy (RT) is administered to the contralateral testis to prevent relapse. CASE PRESENTATION: A 76-year-old man was diagnosed with PTL and received RT as described above. However, despite achieving and maintaining complete remission, a mass diagnosed as diffuse large B-cell lymphoma by tissue biopsy developed in the glans penis 6.5 years after prophylactic RT. We investigated whether the glans penile lymphoma was PTL relapse or a new malignancy by genomic analysis using next-generation sequencing of DNA extracted from two histopathological specimens. CONCLUSIONS: We found the same variant allele fraction in four somatic genes (MYD88, IL7R, BLNK, and FLT3) at similar frequencies, indicating that the glans penile lymphoma had the same origin as the PTL. To the best of our knowledge, this is the first case report of PTL relapse in the glans penis.

TAFRO syndrome is an inflammatory disorder of unknown etiology characterized by thrombocytopenia, anasarca, fever, reticulin fibrosis, renal insufficiency, and organomegaly. Despite great advancements in research on the TAFRO syndrome in the last decade, its diagnosis and treatment are still challenging for most clinicians because of its rarity and severity. Since the initial proposal of the TAFRO syndrome as a distinct disease entity in 2010, two independent diagnostic criteria have been developed. Although these are different in the concept of whether TAFRO syndrome is a subtype of idiopathic multicentric Castleman disease or not, they are similar except for the magnitude of lymph node histopathology. Because there have been no specific biomarkers, numerous diseases must be ruled out before the diagnosis of TAFRO syndrome is made. The standard of care has not been fully established, but interleukin-6 blockade therapy with siltuximab or tocilizumab and anti-inflammatory therapy with high-dose corticosteroids are the most commonly applied for the treatment of TAFRO syndrome. The other immune suppressive agents or combination cytotoxic chemotherapies are considered for patients who do not respond to the initial treatment. Whereas glowing awareness of this disease improves the clinical outcomes of patients with TAFRO syndrome, further worldwide collaborations are warranted.
RESUMEN
BACKGROUND: A new subtype of prostate cancer called treatment-related neuroendocrine prostate carcinoma (t-NEPC) was added to the revised World Health Organization classification of prostate cancer in 2022. t-NEPC cases are increasing, and there is no established standard treatment. METHODS: A 49-year-old male patient was referred to our department for dysuria. A rectal examination and a prostate biopsy revealed stony hardness and prostate adenocarcinoma, respectively. Imaging studies confirmed the presence of multiple bone and lymph node metastases. The patient was started on upfront treatment with androgen deprivation therapy and an androgen receptor signaling inhibitor, which resulted in a significant (>90%) decrease in prostate-specific antigen (PSA) levels. The patient experienced postrenal failure 6 months later, attributable to local disease progression. Concurrently, there was an elevation in neuron-specific enolase (NSE) levels and an enlargement of pelvic lymph node metastases, without PSA progression. RESULTS: Biopsy specimen for cancer genome profiling revealed deletion of BRCA 2 and PTEN, AR amplification, and the presence of the TMPRSS2-ERG fusion gene. Based on increased NSE and BRCA2 mutations, a diagnosis of t-NEPC with BRCA2 mutation was eventually made. The patient received docetaxel chemotherapy and pelvic radiotherapy. Subsequently, he was treated with olaparib. His NSE levels decreased, and he achieved a complete response (CR). However, 18 months following the olaparib administration, brain metastases appeared despite the absence of pelvic tumor relapse, and the patient's PSA levels remained low. Consequently, the patient underwent resection of the brain metastases using gamma knife and whole-brain radiotherapy but died approximately 3 months later. CONCLUSION SUBSECTIONS: Platinum-based chemotherapy is often administered for the treatment of t-NEPC, but there are few reports on the effectiveness of olaparib in patients with BRCA2 mutations. In a literature review, this case demonstrated the longest duration of effectiveness with olaparib alone without platinum-based chemotherapy. Additionally, the occurrence of relatively rare, fatal brain metastases in prostate cancer after a long period of CR suggests the necessity of regular brain imaging examinations.

Hemophagocytic lymphohistiocytosis (HLH), a hyperinflammatory syndrome, is caused by the incessant activation of lymphocytes and macrophages, resulting in damage to organs, including hematopoietic organs. Recently, we demonstrated that repeated lipopolysaccharide (LPS) treatment induces HLH-like features in senescence-accelerated (SAMP1/TA-1) mice but not in senescence-resistant control (SAMR1) mice. Hematopoietic failure in LPS-treated SAMP1/TA-1 mice was attributed to hematopoietic microenvironment dysfunction, concomitant with severely imbalanced M1 and M2 macrophage polarization. Macrophages are a major component of the bone marrow (BM) hematopoietic microenvironment. Clodronate liposomes are useful tools for in vivo macrophage depletion. In this study, we depleted macrophages using clodronate liposomes to determine their role in the hematopoietic microenvironment in SAMP1/TA-1 and SAMR1 mice. Under clodronate liposome treatment, the response between SAMR1 and SAMP1/TA-1 mice differed as follows: (1) increase in the number of activated M1 and M2 macrophages derived from newly generated macrophages and M2-dominant and imbalanced M1 and M2 macrophage polarization in the BM and spleen; (2) severe anemia and thrombocytopenia; (3) high mortality rate; (4) decrease in erythroid progenitors and B cell progenitors in the BM; and (5) decrease in the mRNA expression of erythroid-positive regulators such as erythropoietin and increase in that of erythroid- and B lymphoid-negative regulators such as interferon-γ in the BM. Depletion of residual macrophages in SAMP1/TA-1 mice impaired hematopoietic homeostasis, particularly erythropoiesis and B lymphopoiesis, owing to functional impairment of the hematopoietic microenvironment accompanied by persistently imbalanced M1/M2 polarization. Thus, macrophages play a vital role in regulating the hematopoietic microenvironment to maintain homeostasis.

BACKGROUND: Olanzapine treatment prevents chemotherapy-induced nausea and vomiting (CINV) in patients receiving highly emetogenic chemotherapy (HEC). However, its role in the secondary prevention of breakthrough CINV in real-world cancer care should be further evaluated. METHOD: We conducted a retrospective study on patients receiving olanzapine to prevent breakthrough CINV refractory to standard antiemetic therapy. The major outcome was improvement in CINV, defined as any downgrade in CINV symptoms, according to the Common Terminology Criteria for Adverse Events. Comprete response was defined as no symptoms in CINV, i.e., Grade 0. These outcomes were compared in the HEC versus non-HEC groups and the standard- (5 or 10 mg/day) versus low- (2.5 mg/day) dose groups. The other outcome measurement was adverse events (AEs). RESULTS: We analyzed 127 patients, including 92 women, with a median age of 50 years (range: 19-89 years). Baseline CINV severity was grade 1, 2, and 3 in 18%, 69%, and 13% of the patients, respectively. After prophylaxis with olanzapine at doses of 2.5, 5, or 10 mg/day, improvement was observed in 105 (83%) patients, with a complete response in 42 patients (33%). The improvement and complete remission rates for the HEC (n = 96) and non-HEC (n = 31) groups were 86% and 71% (p = 0.048) versus 38% and 19% (p = 0.062), respectively. The rates for the standard- (n = 98) and low- (n = 29) dose groups were 86% and 82% (p = 0.568) versus 28% and 52% (p = 0.015), respectively. Thirty-four patients (27%) experienced olanzapine-related AEs, mainly somnolence (n = 28). Grade 3 or higher AEs were not observed. CONCLUSION: Our study results support the clinical application of olanzapine for the secondary prevention of breakthrough CINV.
RESUMEN
Pulmonary veno-occlusive disease (PVOD) is an extremely rare condition in oncology practice. Although PVOD is clinically similar to pulmonary arterial hypertension, the conditions differ in terms of pathophysiology, management, and prognosis. This report discusses the case of a 47-year-old woman who developed dyspnea and fatigue after high-dose cyclophosphamide chemotherapy and autologous hematopoietic stem cell transplantation for relapsed lymphoma. The patient exhibited tachycardia, tachypnea, and hypotension, but other findings in the physical examination were unremarkable. The imaging studies showed no evidence of pulmonary embolism, but multiple ground-glass opacities and bilateral pleural effusions were observed on chest high-resolution computed tomography scans. In the right heart catheterization study, the mean pulmonary artery pressure and pulmonary vascular resistance were 35 mm Hg and 5.93 Wood units, respectively, with a normal pulmonary capillary wedge pressure of 10 mm Hg. Pulmonary function tests revealed a remarkable reduction in the percentage predicted value of diffusing capacity of the lungs for carbon monoxide to 31%. Lymphoma progression, collagen diseases, infectious diseases such as human immunodeficiency virus or parasitic infections, portal hypertension, and congenital heart disease were carefully excluded as these are also capable of causing pulmonary arterial hypertension. Thereafter, we reached a final diagnosis of PVOD. The patient was treated with supplemental oxygen and a diuretic during 1 month of hospitalization, which relieved her right heart overload symptoms. Herein, we present the patient's clinical course and diagnostic workup because misdiagnosis or inappropriate treatment can lead to unfavorable outcomes in patients with PVOD.
RESUMEN
A 70-year-old woman was admitted to the hospital with loss of appetite and melena. She was diagnosed with multiple myeloma 7 years ago and had been on carfilzomib, lenalidomide, and dexamethasone (KRd) therapy for a month because her disease had a relapsed/refractory. On admission, her laboratory tests revealed hemolytic anemia with schizocytes, thrombocytopenia, and acute renal dysfunction. TMA (thrombotic microangiography) caused by carfilzomib was suspected. The possibility of thrombotic thrombocytopenia was considered, and steroid pulse therapy was initiated. Her condition improved significantly after she stopped taking carfilzomib, plasma exchange, hemodiafiltration, steroid pulse therapy, and abstaining from food. The previously reported cases of carfilzomib-induced TMA included fever, gastrointestinal symptoms (nausea/vomiting, diarrhea), and acute renal disorders (lower extremity edema, decreasing urine output). As far as we know, this is the first case of carfilzomib-induced TMA with bleeding as the first symptom.

BACKGROUND: Pegfilgrastim is widely used for the prevention of febrile neutropenia (FN) in patients receiving myelosuppressive chemotherapy for various types of cancer. However, pegfilgrastim-induced bone pain (PIBP) is a relevant adverse event occurring during cancer treatment. Thus, we aimed to determine the risk factors for PIBP in real-world clinical practice. MAIN BODY: We retrospectively collected the clinical records of patients who received pegfilgrastim to support myelosuppressive chemotherapy with at least a 10% risk of FN between 2015 and 2018 at our center. Patients received pegfilgrastim 3.6 mg between days 2 and 7 after chemotherapy administration (day 1) for primary or secondary prophylaxis against FN. All adverse events were recorded according to the Common Terminology Criteria for Adverse Events. Patients who experienced intermittent bone pain in the back, femur, or other anatomic sites after the pegfilgrastim administration were considered to have PIBP. To evaluate the relationship between PIBP incidence and patient characteristics, we performed univariate and multivariate logistic regression analyses to calculate the odds ratios (ORs) of possible risk factors for PIBP. We analyzed the data of 305 patients (median age: 63 years), who underwent 1220 chemotherapy cycles with pegfilgrastim per cycle. Univariate analysis revealed that female sex (vs. male sex), younger age (< 55 years vs. ≥ 55 years), and solid cancers (vs. hematologic cancers) had significantly higher ORs (p < 0.05). However, only younger age (< 55 years) was an independent risk factor for PIBP on multivariate analysis (OR 3.62, 95% confidence interval 1.51-8.69, p = 0.004). CONCLUSIONS: Younger age (< 55 years) was significantly associated with a higher risk of PIBP among patients receiving chemotherapy with a ≥ 10% risk of FN. Therefore, oncologists should meticulously formulate management plan for PIBP in younger patients after administering pegfilgrastim.
RESUMEN
We investigated the incidence, risk factors, and clinical outcomes of cytomegalovirus (CMV) disease in patients with B-cell lymphoma treated with a bendamustine-containing regimen. The incidence of CMV disease was analyzed after starting treatment with 139 regimens in 126 patients. Clinically significant CMV disease was observed in seven patients. The median duration between bendamustine initiation and the diagnosis of CMV disease was 69 d (range, 40-233), and the median of cycles completed at onset was 2 (range, 1-6). Furthermore, the incidence of CMV disease was significantly higher in the elderly patients than that in the younger patients. The target organs of CMV disease were the liver, gastrointestinal tract, lungs, and retinas. Antiviral therapy was administered to all patients. However, the recurrence of CMV disease was observed in two patients. This study provides information that could contribute to clinicians' decision-making on lymphoma therapy using bendamustine.

Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of B-cell lymphoma characterized by aggressive disease progression with a high incidence of central nervous system (CNS) involvement. We retrospectively analyzed 16 patients with de novo IVLBCL treated at our hospital between 2004 and 2018 with either standard therapy plus CNS-directed therapy or standard therapy alone. CNS-directed therapy was associated with a significantly better 2-year CNS-free survival (100% vs. 63%, p = 0.0191), despite no significant effects on progression-free or overall survival. Further studies should assess CNS-focused treatment in patients with IVLBCL with or without primary CNS involvement.
RESUMEN
INTRODUCTION: The standard of care for diffuse large B-cell lymphoma (DLBCL) is rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). However, its ideal dose intensity varies among cases. AREAS COVERED: This review provides the latest insights on the dose intensity of R-CHOP for DLBCL patients. Specifically, we discussed the optimal dose intensity for elderly patients, the optimal number of treatment cycles for limited or advanced-stage diseases, and the role of dose-intensified therapies or adding targeted inhibitors. EXPERT OPINION: Performing a comprehensive or simplified geriatric assessment can distinguish elderly DLBCL patients who will likely benefit from curative R-CHOP. Very elderly or medically unfit patients may need dose reduction in R-CHOP; the Age, Comorbidities, and Albumin index may aid decision-making. Four cycles of R-CHOP followed by two rituximab cycles comprise a new standard for low-risk, limited-stage DLBCL patients. Compared to eight cycles, six cycles of R-CHOP have similar efficacy and fewer toxicities for advanced-stage DLBCL. Dose-intensified therapy is not recommended in most DLBCL cases but may be considered for patients with double (or triple)-hit lymphoma. Applying targeted inhibitors and not merely escalating R-CHOP dose intensity through molecular subtyping will improve the treatment outcome for DLBCL.
Diffuse large B-cell lymphoma (DLBCL) is one of the most common blood cancers. Patients with DLBCL are usually treated with a standard (immuno-) chemotherapy called R-CHOP, which stands for rituximab, cyclophosphamide, hydroxydaunorubicin (doxorubicin), Oncovin, and prednisone. Of these, cyclophosphamide and doxorubicin are particularly toxic but effective. Therefore, the dosages of these drugs are adjusted according to the patient's body size. However, the ideal amounts of these drugs (dose intensity) can vary from case to case. For instance, the regular dose intensity of R-CHOP is too toxic for some people, such as very older patients. Furthermore, ideal total amounts of these drugs, that is, ideal cycle numbers of R-CHOP, are also different between patients with limited disease and advanced disease. Therefore, oncology/hematology researchers have been seeking the optimal dose intensity of R-CHOP in each patient with DLBCL for years. The goal of this review is to provide the latest insights on the ideal dose intensity of R-CHOP in DLBCL treatment. In this article, we discuss: how R-CHOP was established as the standard of care for DLBCL, how to identify candidates for standard R-CHOP among older patients, how to adjust the dose intensity of R-CHOP for patients who are not candidates for standard R-CHOP, optimal cycle number of R-CHOP for limited-disease DLBCL, optimal cycle number of R-CHOP for advanced DLBCL, how to treat patients with a large mass, and the role of more intensive therapies other than R-CHOP in DLBCL treatment. Finally, we demonstrate how experts determined the dose intensity of R-CHOP for some example cases with DLBCL.

Background Infusion-related reactions (IRRs) during rituximab administration are occasionally severe and remain problematic in oncology practice. Aim To establish a safer, risk-stratified rituximab protocol for patients with B-cell lymphoma. Method We stratified patients into low-, moderate-, and high-risk groups according to the number of risk factors for IRRs, specifically, low-grade histology and bulky tumors (> 10 cm): Then, the administrating schedule of rituximab (375 mg/m2, diluted in 1 mg/mL concentration) was individualized. For the first rituximab cycle, the low- and moderate-risk groups underwent conventional infusion #1 (25-200 mg/h, ~4.3 h), and the high-risk group underwent long infusion (25-100 mg/h, 6.8 h). Patients in the low-, moderate-, and high-risk groups without IRRs in the first cycle underwent short infusion (100-400 mg/h, 2.3 h), conventional infusion #2 (100-200 mg/h, 3.5 h), and conventional infusion #1, respectively. Patients with IRRs in the first cycle received a second rituximab cycle with the same schedule as the first cycle. The procedure for the third cycle was at the attending physician's discretion. Results Among 81 patients, the overall incidence of IRRs was 28%. IRR incidences in the low- (n = 39), moderate- (n = 35), and high-risk groups (n = 7) were 31%, 20%, and 57%, respectively. All IRRs were grade ≤ 2. The overall conversion rate to short infusion in the third cycle was 54%, without any IRRs. Conclusions Our step-by-step rituximab protocol demonstrated a fewer incidence of severe IRRs among B-cell lymphoma patients receiving rituximab.

BACKGROUND: Some chemotherapeutic agents cause carnitine deficiency, which causes general fatigue. However, there is no study on carnitine deficiency in patients with chronic myeloid leukemia (CML) during tyrosine kinase inhibitor (TKI) therapy. OBJECTIVE: In this study, we investigated carnitine concentrations in patients with CML receiving TKI therapy. METHOD: This study included patients with well-controlled CML. Total carnitine and free carnitine concentrations were evaluated using the enzyme cycling method. The brief fatigue inventory (BFI) and cancer fatigue scale (CFS) were used to assess general fatigue developed during TKI therapy. RESULTS: Fifty-five patients on TKI therapy were included. Of these, 12 (21.8%) patients had low free carnitine concentrations. Free carnitine concentrations were higher in men than in women. Younger age was closely associated with lower free carnitine concentrations. TKI type, TKI dose, treatment response, or therapy duration were not associated with free carnitine concentrations. None of the scores (the global fatigue score with the BFI and CFS score) correlated with carnitine concentrations. Concentrations of free carnitine in patients in the treatment-free remission group were slightly higher than those in the TKI group, with only 9.1% having a low concentration of free carnitine. CONCLUSION: Carnitine deficiency is probably not a major cause of general fatigue but may occur in patients with CML receiving TKI therapy.

Personalized medicine aims to match the right drug with the right patient by using specific features of the individual patient's tumor. However, current strategies of personalized therapy matching provide treatment opportunities for less than 10% of patients with cancer. A promising method may be drug profiling of patient biopsy specimens with single-cell resolution to directly quantify drug effects. We prospectively tested an image-based single-cell functional precision medicine (scFPM) approach to guide treatments in 143 patients with advanced aggressive hematologic cancers. Fifty-six patients (39%) were treated according to scFPM results. At a median follow-up of 23.9 months, 30 patients (54%) demonstrated a clinical benefit of more than 1.3-fold enhanced progression-free survival compared with their previous therapy. Twelve patients (40% of responders) experienced exceptional responses lasting three times longer than expected for their respective disease. We conclude that therapy matching by scFPM is clinically feasible and effective in advanced aggressive hematologic cancers. SIGNIFICANCE: This is the first precision medicine trial using a functional assay to instruct n-of-one therapies in oncology. It illustrates that for patients lacking standard therapies, high-content assay-based scFPM can have a significant value in clinical therapy guidance based on functional dependencies of each patient's cancer.See related commentary by Letai, p. 290.This article is highlighted in the In This Issue feature, p. 275.

BACKGROUND: Hepatocellular carcinoma (HCC) occasionally presents with simultaneous or metachronous primary malignancies of other organs. Despite the limited scope of cytocidal anticancer drugs or molecular targeted agents, immune checkpoint inhibitors (ICIs) can still be used for various malignancies. Here, we present cases of double cancers including HCC treated with ICIs. CASE REPORT: Case 1: A 70-year-old man with lung cancer and 80-mm HCC underwent nivolumab therapy. The sizes of both cancers remained constant for nine months. Case 2: A 58-year-old man with pharyngeal cancer and HCC. Nivolumab was administered, but was withdrawn after one session because of progressive disease. Case 3: A 71-year-old man with a 5 cm HCC invading the inferior vena cava, and early esophageal cancer. HCC showed a significant volume reduction and esophageal cancer demonstrated slight improvement by atezolizumab and bevacizumab therapy. CONCLUSION: A combination therapy including ICI is a promising treatment option for HCC with concurrent malignancies.

OBJECTIVES: To identify prognostic factors for TAFRO syndrome, a rare inflammatory disorder of unknown etiology characterized by thrombocytopenia, anasarca, fever, reticulin myelofibrosis, renal dysfunction, and organomegaly. METHODS: Data of patients with TAFRO syndrome were extracted from a Japanese patient registry. Patients were divided into groups according to the clinical and laboratory parameters at initial presentation. Cut-off values for the laboratory parameters were determined using receiver operating characteristic curve analysis and by clinical relevance. Patient survival was analyzed by the Kaplan-Meier method. Univariable analysis was performed using log-rank tests. Multivariable analyses were performed with the logistic regression model and the Cox proportional hazards model. RESULTS: We extracted the data of 83 patients with TAFRO syndrome from the registry. Univariable analysis identified several potential prognostic factors. Of these factors, age ≥60 years and D-dimer ≥18 µg/dL remained significant predictors of poor overall survival in the multivariable Cox proportional hazards model. Based on these results, we developed a simple prognostic scoring system for TAFRO syndrome (TS-PSS). CONCLUSION: Patients in our cohort were stratified into low, intermediate, and high-risk groups by the TS-PSS. This system should be verified with independent patient cohorts in future studies.

Background/Aim: We assessed the prognosis of patients with refractory or relapsed multiple myeloma (RRMM) by focusing on the change in absolute lymphocyte counts (ALCs) after lenalidomide and dexamethasone (Ld) initiation. Patients and Methods: In total, 72 patients with RRMM were treated with Ld. ALCs were evaluated before treatment and at 1, 2, and 3 months after Ld initiation. The median ALCs in the entire cohort before and at 1, 2, 3 months after Ld initiation were 1,131, 1,059, 1,222, and 1,162/µl, respectively. Results: ALCs before Ld initiation did not affect time to next treatment (TNT) or overall survival (OS). However, the patients with ALCs equal to or greater than the median at 3 months showed relatively better TNT than those with lower lymphocyte counts, with a significant difference. OS was also significantly longer in patients with higher ALCs. Conclusion: Immunomodulation by lenalidomide may improve prognosis in patients with RRMM.
