Abstract Daratumumab (DARA) has shown impressive activity in combination with other agents for the treatment of multiple myeloma (MM). We conducted a phase 1b study to assess the safety and preliminary efficacy, as well as potential mechanisms of action, of DARA (16 mg/kg) in combination with a weekly schedule of subcutaneous bortezomib (1.3-1.5 mg/m2), cyclophosphamide (150-300 mg/m2), and dexamethasone (40 mg) (CyBorD DARA) as initial induction before autologous stem cell transplantation (ASCT). Eligible patients were ≤70 years of age with untreated MM requiring treatment and who lacked significant comorbidities. A total of 18 patients were enrolled. Their median age was 56 years (range, 32-66 years), and all patients had Eastern Cooperative Oncology Group performance status ≤1. The International Staging System stages were I, II, and III in 78%, 17%, and 6% of patients, respectively; 28% of patients had high-risk genetic features. There was no dose-limiting toxicity, and the incidence of grade 3 or 4 infection or neutropenia was <10%. On an intention-to-treat basis, 94% achieved ≥very good partial response with ≥complete response in 44% of patients. Among 14 of 15 patients who underwent ASCT and were evaluable for response, all 14 achieved at least very good partial response, with 8 (57%) of 14 achieving complete response. After ASCT, 10 (83%) of 12 patients in whom minimal residual disease analysis was possible were negative at a sensitivity of 10−5 (56% on intention-to-treat/whole study population) according to next-generation sequencing. Flow cytometry analysis of patient samples indicated CyBorD DARA induced activation of macrophage-mediated antibody-dependent cellular phagocytosis. This trial was registered at www.clinicaltrials.gov as #NCT02955810.

Background: Treatment with gemcitabine/nab-paclitaxel confers a survival benefit over gemcitabine monotherapy in patients with advanced pancreatic cancer (APC). However, such treatment can be associated with significant toxicities especially in older patients and carries practical disadvantages related to a weekly schedule along with financial cost. We retrospectively analyzed patients >65 years of age with APC who received a modified biweekly regimen of gemcitabine/nab-paclitaxel to evaluate efficacy and toxicity. Methods: Patients aged >65 years with chemo-naïve APC with Eastern Cooperative Oncology Group performance status ⩽2 were studied. Patients were treated with a modified regimen of gemcitabine 1000 mg/m2 and nab-paclitaxel 125 mg/m2 every 2 weeks on days 1 and 15 of a 28-day cycle. Patients were evaluated for progression-free survival (PFS) and overall survival (OS) with analyses performed using the Kaplan–Meier method. Adverse events were recorded on the day of chemotherapy. Cancer antigen 19.9 was measured in every cycle and restaging scans were performed every two cycles. Results: A total of 73 patients (median age: 73 years; range: 66–93) were treated with biweekly gemcitabine/nab-paclitaxel as first-line treatment. The median OS and PFS were 9.1 months and 4.8 months, respectively. Around 66% of patients received growth-factor support based on American Society of Clinical Oncology guidelines and no patient developed neutropenic fever. The incidences of grade ⩾3 toxicity for neutropenia, anemia, thrombocytopenia, and neurotoxicity were 2%, 7%, 3%, and 5%, respectively. Dose reductions of gemcitabine/nab-paclitaxel were required in 10% and 4% patients, respectively. Conclusion: In patients older than >65 years of age with APC, a modified regimen of biweekly gemcitabine/nab-paclitaxel was found to be effective when compared with the historical control from the MPACT study. This regimen allowed for fewer dose reductions, reduced healthcare costs from additional appointments, travel-related cost, as well as a favorable side-effect profile while maintaining efficacy. Though retrospective in nature, this study underlines the need for further investigation, particularly in elderly patients with poor performance status, such as those with pancreatic cancer, and in order to combine with a third agent, such as a targeted treatment or immunotherapy.

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors’ suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. An 84-year-old woman presented with bone pain and lytic bone lesions in April 2010. Diagnosis of multiple myeloma was based on the presence of an immunoglobulin G lambda serum M protein (4,784 mg/dL) and confirmed by the findings of bone marrow plasma cell infiltration, with t(11;14) chromosomal abnormality detected by fluorescence in situ hybridization analysis. The patient’s medical history was significant for hypertension; she had an Eastern Cooperative Oncology Group performance status of 1, International Staging System (ISS) stage of 1, and Durie–Salmon stage of IIIA. In May 2010, the patient was enrolled in a randomized phase III trial comparing different lenalidomide-based treatments and received induction with lenalidomide plus dexamethasone (nine cycles) followed by lenalidomide maintenance. The patient started treatment with lenalidomide 25 mg per day for 21 days and reduced-dose dexamethasone 20 mg per week per protocol because of age. Induction was well tolerated; no relevant complications occurred, except for grade 1 fatigue and grade 1 diarrhea. Best response was partial response. In March 2011, she started maintenance with lenalidomide 10 mg per day. A dose reduction of lenalidomide 5 mg per day was required because of grade 2 diarrhea. In July 2015, the patient experienced relapse, with painful collapse of L3 vertebral body.

Liver resection surgery is the most commonly used treatment strategy for patients diagnosed with hepatocellular carcinoma (HCC). However, there is still a chance for recurrence in these patients despite the survival benefits of this procedure. This study aimed to explore recurrence-related genes (RRGs) and establish a genomic-clinical nomogram for predicting postoperative recurrence in HCC patients. A total of 123 differently expressed genes and three RRGs (PZP, SPP2, and PRC1) were identified from online databases via Cox regression and LASSO logistic regression analyses and a gene-based risk model containing RRGs was then established. The Harrell’s concordance index (C-index), receiver operating characteristic (ROC) curves and calibration curves showed that the model performed well. Finally, a genomic-clinical nomogram incorporating the gene-based risk model, AJCC staging system, and Eastern Cooperative Oncology Group performance status was constructed to predict the 1-, 2-, and 3-year recurrence-free survival rates (RFS) for HCC patients. The C-index, ROC analysis, and decision curve analysis were good indicators of the nomogram’s performance. In conclusion, we identified three reliable RRGs associated with the recurrence of cancer and constructed a nomogram that performed well in predicting RFS for HCC patients. These findings could enrich our understanding of the mechanisms for HCC recurrence, help surgeons predict patients’ prognosis, and promote HCC treatment.

Abstract Burkitt lymphoma (BL) is common in sub-Saharan Africa (SSA). In high-income countries, BL is highly curable with chemotherapy. However, there are few prospective studies from SSA describing nonpediatric BL and no regional standard of care. Thirty-five participants age 15 years or older with newly diagnosed BL were enrolled in Malawi from 2013 to 2018. Chemotherapy was administered according to institutional guidelines, with concurrent antiretroviral therapy if HIV infected. Median age was 21 years (range, 15-61) and 15 participants (43%) were HIV infected. Twenty-seven participants (77%) had stage III to IV disease, and 19 (54%) had Eastern Cooperative Oncology Group performance status >1. Among HIV-infected participants, median CD4 count was 130 (range, 29-605) and 10 (67%) had suppressed HIV viral load. Four participants (11%) died before receiving chemotherapy. First-line chemotherapy consisted of: cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) (n = 22 [71%]); infusional etoposide, prednisolone, vincristine, cyclophosphamide, and doxorubicin (n = 4 [13%]); high-dose methotrexate-based chemotherapy (n = 4 [13%]); and rituximab plus CHOP (n = 1 [3%]). Among 28 evaluable participants, 14 (50%) achieved a complete response. Median overall survival (OS) was 7 months; 1-year OS was 40% (95% confidence interval [CI], 24%-56%). Sixteen (73%) of 22 deaths were a result of disease progression. Compared with CHOP, more intensive chemotherapy was associated with decreased mortality (hazard ratio, 0.24; 95% CI, 0.05-1.02; P = .05). This is among the best characterized prospective cohorts of nonpediatric BL in SSA. Most deaths resulted from progressive BL. Patients who received more intensive therapy seemed to have better outcomes. Defining optimal approaches is an urgent priority in SSA.

9523 Background: The phase 3 IMspire150 study showed that first-line A+V+C improved investigator-assessed PFS vs placebo (P)+V+C in BRAFV600E/K mutation–positive advanced melanoma (hazard ratio 0.78; P=.0249). Prior biomarker analyses showed that IFN-g or TMB > 10 mut/Mb were associated with greater PFS benefits with A+V+C (Lewis et al. J ImmunoTher Cancer 2020;8:A188-A189). We further evaluated the association of these biomarkers with outcomes. Methods: Exploratory recursive partitioning analysis (RPA) was used to model associations between PFS and age ( < 65 vs ≥65 y), Eastern Cooperative Oncology Group performance status (0 vs 1), liver metastases (yes vs no), metastatic sites (≤3 vs > 3), sum of longest tumor diameters ( < 44 mm vs ≥44 mm), baseline LDH (normal [n] vs elevated [e]), TMB ( < 10 vs ≥10 mut/Mb), PD-L1 (negative vs positive), and IFN-g (high [h; > Quartile 3; Q3] vs intermediate [ > Q1 and ≤Q3] vs low [≤Q1]). Time-to-event analyses were summarized using Kaplan-Meier estimates. Results: The RPA analysis included 208/256 (81.3%) patients (pts) from the A+V+C arm of IMspire150 for whom LDH, TMB, IFN-g, and PD-L1 data were available. RPA showed that LDH was associated with PFS. In pts treated with A+V+C and n-LDH, h-IFN-g signature was associated with longer PFS and higher rates of objective response (OR) and complete response (CR) vs low/intermediate (l/i) IFN-g (2-y PFS: 59% vs 38%; ORR: 77% vs 69%; CR: 38% vs 15%, respectively); TMB ≥10 mut/Mb was associated with more favorable outcomes in pts with e-LDH (Table). In contrast, neither IFN-g nor TMB discriminated PFS outcomes in n-LDH or e-LDH pt subgroups receiving P+V+C. Pts with e-LDH and TMB < 10 mut/Mb had poor PFS outcomes, with 2-y PFS rates of 9% and 3% and lower rates of OR (51% and 62%) and CR (5% and 9%) in the A+V+C and P+V+C arms, respectively. Similar trends were observed for duration of response (DOR), and for the subset of pts with BRAFV600E mutation–positive melanoma. A+V+C improved PFS vs P+V+C across all subgroups with the exception of e-LDH and TMB < 10. Conclusions: IFN-g and TMB discriminated PFS benefit in pts receiving A+V+C but not for those receiving P+V+C. Durable responses were observed for pts treated with A+V+C in the n-LDH + h-IFNg subgroups.[Table: see text]

AbstractIn the phase 3 MAIA study of patients with transplant-ineligible newly diagnosed multiple myeloma (NDMM), daratumumab plus lenalidomide/dexamethasone (D-Rd) improved progression-free survival (PFS) versus lenalidomide/dexamethasone (Rd). We present a subgroup analysis of MAIA by frailty status. Frailty assessment was performed retrospectively using age, Charlson comorbidity index, and baseline Eastern Cooperative Oncology Group performance status score. Patients were classified as fit, intermediate, non-frail (fit + intermediate), or frail. Of the randomized patients (D-Rd, n = 368; Rd, n = 369), 396 patients were non-frail (D-Rd, 196 [53.3%]; Rd, 200 [54.2%]) and 341 patients were frail (172 [46.7%]; 169 [45.8%]). After a 36.4-month median follow-up, non-frail patients had longer PFS than frail patients, but the PFS benefit of D-Rd versus Rd was maintained across subgroups: non-frail (median, not reached [NR] vs 41.7 months; hazard ratio [HR], 0.48; P < 0.0001) and frail (NR vs 30.4 months; HR, 0.62; P = 0.003). Improved rates of complete response or better and minimal residual disease (10–5) negativity were observed for D-Rd across subgroups. The most common grade 3/4 treatment-emergent adverse event in non-frail and frail patients was neutropenia (non-frail, 45.4% [D-Rd] and 37.2% [Rd]; frail, 57.7% and 33.1%). These findings support the clinical benefit of D-Rd in transplant-ineligible NDMM patients enrolled in MAIA, regardless of frailty status.

We present the first reported case of pseudocirrhosis arising after a dramatic response to chemotherapy in metastatic gastric cancer. A 74-year-old man was diagnosed with gastric adenocarcinoma having multiple liver metastases. His general condition was poor, with an Eastern Cooperative Oncology Group performance status of 3, inadequate oral intake, and jaundice (total bilirubin 2.8 mg/dl). Chemotherapy with oxaliplatin, L-leucovorin, and 5-fluorouracil (modified FOLFOX-6) was initiated. After four treatment cycles, he experienced a marked regression of liver metastases; however, he developed massive ascites with a lobular liver surface and segmental atrophy, which were consistent with pseudocirrhosis. Chemotherapy was continued along with ascites management. Thereafter, ascites disappeared, and a complete response of the metastatic lesions was achieved at 11 months after initial treatment. He had no evidence of disease progression at 30 months after initial chemotherapy. This report suggests clinicians should recognize this entity, even in gastric cancer metastatic to the liver.

We investigated the efficacy of 2-chlorodeoxyadenosine (2-CdA) therapy in patients with mycosis fungoides (MF) and the Sezary syndrome (SS). Between February 1991 and November 1993, 21 patients with relapsed or refractory MF/SS were treated with 2-CdA. 2-CdA was administered by continuous intravenous infusion at a dose of 0.1 mg/kg/d for 7 days initially (13 patients), but was subsequently reduced to 5 days (nine patients) due to hematologic toxicity. All patients had failed to respond to at least one prior treatment for MF/SS (median number of total prior therapies, five; median number of systemic prior therapies, three) and had an Eastern Cooperative Oncology Group performance status of two or better. Cycles were administered at 28-day intervals. Assessable patients received at least 5 days of 2-CdA. Fourteen patients received more than one cycle of 2-CdA. An overall response rate of 28% was achieved. Three patients (14%) had a complete response with a median duration of 4.5 months (range, 2.5 to 16). Three (14%) had a partial response with a median duration of 2 months (range, 2 to 4). Fifteen patients (72%) had no response. The most significant toxicities encountered were bone marrow suppression (62% of patients) and infectious complications (62% of patients). Thirty-eight percent of patients experienced no toxicity from 2-CdA. 2-CdA has activity as a single agent in patients with previously treated relapsed MF/SS. Studies in less heavily pretreated individuals with 2-CdA alone or in combination will be undertaken.

Abstract Background ： During the past decade, bortezomib, lenalidomide and dexamethasone (VRd) followed by lenalidomide maintenance has become one of the most effective first-line regimens in multiple myeloma (MM) and been recommended by many guidelines. However, when disease relapses after VRd induction and lenalidomide maintenance, further generation of proteasome inhibitors or immunomodulator drugs, or agents with different mechanism should be considered. Pomalidomide, a new-generation oral immunomodulator drug, can overcome lenalidomide resistance and has better efficacy and safety in MM patients. Pomalidomide has a synergistic effect with proteasome inhibitor and dexamethasone, which has been proved more effective than pomalidomide and dexamethasone dual-drug regimen in relapsed or refractory MM (RRMM) patients (Richardson, et al. Lancet Oncol 2019). The overall response rate (ORR) of lenalidomide retreatment is only 54% (Sumit, et al. Blood 2011). A convenient and safe pan-oral regimen, ixazomib, pomalidomide and dexamethasone (IxaPd) is expected to improve the efficacy and survival in RRMM patients. The purpose of this study is to evaluate the efficacy and safety of IxaPd regimen in RRMM patients who have received lenalidomide in China. Study Design and Methods: This multi-center open-label, single-arm study (NCT04989140) will enroll patients with measurable M protein who have received 1 to 3 prior lines of therapy (including lenalidomide) with documented disease progression during or after their most recent treatment. Patients aged ≥18 years with Eastern Cooperative Oncology Group Performance Status 0-2, expected overall survival (OS) ≥3 months, and who provide informed consent will be eligible. Patients with prior exposure to pomalidomide, ixazomib and those intolerant/refractory to bortezomib will be excluded. Eligible 60 patients will be enrolled in this IxaPD regimen. Clinical and laboratory parameters will be recorded at baseline. Cytogenetic abnormalities are tested via fluorescence in situ hybridization (FISH) in CD138 sorted myeloma cells. Ixazomib 4 mg on days 1, 8 and 15 every 28 days, pomalidomide 4mg qd day 1-21 every 28-day, dexamethasone 40 mg (20 mg for patients &gt;75 years of age) every week will be administrated. Treatment will continue until disease progression or unacceptable toxicity. Drug doses will be adjusted or withdrawn according to the degree of toxicities. The primary endpoint is progression free survival (PFS), the secondary endpoints include OS, time to next treatment (TTNT), ORR, safety. Patients are stratified into subpopulation on the basis of cytogenetic abnormalities, prior treatment lines and exposure drugs, ect. PFS, OS and TTNT were analyzed by Kaplan-Meier survival plot. Response will be evaluated according to International Myeloma Working Group (IMWG) 2016 criteria, and done at baseline and each cycle from 1-5, then every other cycle till cycle 13, and every three cycles till cycle 28 if the subjects do not relapse. Patients who reach complete response (CR) need to perform a minimal residual disease (MRD) test via next-generation flow (NGF) . Conclusion: This is the first prospective clinical study to examine the efficacy and safety of pan-oral IxaPd regimen for RRMM in Chinese patients.

The purpose of this study was to determine the safety and efficacy of TLK286 (TELCYTA™), a glutathione analog prodrug, in patients with platinum and paclitaxel refractory or resistant ovarian carcinoma. Thirty-six patients with measurable disease were enrolled. TLK286 was administered at 1000 mg/m2 intravenously every 3 weeks. The endpoints were objective response rate assessed by Response Evaluation Criteria in Solid Tumors (RECIST) and survival. Adverse events were graded using the National Cancer Institute Common Toxicity Criteria. Thirty-four platinum refractory or resistant patients (94%) were evaluable for objective tumor response. Five patients (15%) had objective tumor responses, including one durable complete response (CR) of greater than 3 years and continuing. The disease stabilization rate was 50%, including one CR (3%), four partial responses (12%), and 12 durable disease stabilizations (35%). Responses were accompanied by improvement in clinical symptoms and Eastern Cooperative Oncology Group Performance Status (ECOG PS) and decline in CA125 levels. Median survival was 423 days with survival of 60% at 1 year and 40% at 18 months. TLK286 was well tolerated in this population. TLK286 is an active agent in chemotherapy-resistant ovarian cancer. Further studies of TLK286 in platinum and paclitaxel refractory or resistant ovarian cancer are in progress.
