Item Adverse Health Outcomes among U.S. Testicular Cancer Survivors after Cisplatin-Based Chemotherapy vs. Surgical Management(Oxford, 2019-10) Agrawal, Vaibhav; Dinh, Paul C., Jr.; Fung, Chunkit; Monahan, Patrick O.; Althouse, Sandra K.; Norton, Kelli; Cary, Clint; Einhorn, Lawrence; Fossa, Sophie D.; Adra, Nabil; Travis, Lois B.; Medicine, School of MedicineWe evaluated for the first time adverse health outcomes (AHOs) among U.S. testicular cancer survivors (TCS) given chemotherapy (n = 381) vs. surgery-only patients (n = 98) managed at a single institution, accounting for non-treatment-related risk factors to delineate chemotherapy’s impact. Chemotherapy consisted largely of bleomycin-etoposide-cisplatin (BEP) administered in 3 or 4 cycles (BEPX3, n = 235; BEPX4, n = 82). Incidence of ≥ 3 AHOs was lowest in surgery-only TCS and increased with BEPX3, BEPX4 and other cisplatin-based regimens (12.2%, 40.8%, 52.5%, 54.8%; P<0.0001). Multivariate modeling assessed associations of risk factors and treatment with hearing impairment, tinnitus, peripheral neuropathy, and Raynaud phenomenon. Risk for each AHO significantly increased with both increasing chemotherapy burden (P < 0.0001) and selected modifiable risk factors (P < 0.05): hypertension (OR = 2.40) and noise exposure (OR ≥ 2.3) for hearing impairment; noise exposure for tinnitus (OR ≥ 1.69); peripheral vascular disease for neuropathy (OR = 8.72), and current smoking for Raynaud phenomenon (OR = 2.41). Clinicians should manage modifiable risk factors for AHOs among TCS.Item Carboplatin and Etoposide With or Without Palifosfamide in Untreated Extensive-Stage Small-Cell Lung Cancer: A Multicenter, Adaptive, Randomized Phase III Study (MATISSE)(ASCO, 2017-08) Jalal, Shadia I.; Lavin, Philip; Lo, Gregory; Lebel, Francois; Einhorn, Lawrence; Medicine, School of MedicinePurpose To evaluate the efficacy of the addition of palifosfamide to carboplatin and etoposide in extensive stage (ES) small-cell lung cancer (SCLC). Patients and Methods MATISSE was a randomized, open-label, adaptive phase III study. Previously untreated patients with ES SCLC were randomly assigned in a 1:1 fashion to receive carboplatin at area under the serum concentration-time curve 5 on day 1 plus etoposide 100 mg/m2 per day on days 1 to 3 every 21 days (CE) or carboplatin at area under the serum concentration-time curve 4 on day 1 plus etoposide 100 mg/m2 per day plus palifosfamide 130 mg/m2 per day on days 1 to 3 every 21 days (PaCE). The primary end point was overall survival. Results In all, 188 patients were enrolled; 94 patients received CE and 94 patients received PaCE. The median age on both arms was 61 years. Six cycles of chemotherapy were completed on both arms of the study by approximately 50% of the patients. Serious adverse events were documented and did not differ significantly between patients receiving PaCE and those receiving CE. Median overall survival was similar between both arms with 10.03 months on PaCE and 10.37 months on CE (P = .096). Conclusion The addition of palifosfamide to CE failed to improve survival in ES SCLC.Item Cisplatin-associated neuropathy characteristics compared to those associated with other neurotoxic chemotherapy agents (Alliance A151724)(Springer, 2021) Albany, Costantine; Dockter, Travis; Wolfe, Eric; Le-Rademacher, Jennifer; Wagner-Johnston, Nina; Einhorn, Lawrence; Lafky, Jackie; Smith, Ellen; Pachman, Deirdre; Staff, Nathan; Ma, Cynthia; Loprinzi, Charles L.; Costello, Brian A.; Medicine, School of MedicinePurpose: The current project was developed to obtain natural history information regarding cisplatin-induced peripheral neuropathy in males with testicular/germ cell cancers and to compare such neuropathy data with similarly obtained data in patients receiving other chemotherapy drugs in similarly conducted clinical trials. Methods: Patients without baseline neuropathy symptoms, who were initiating cisplatin-based chemotherapy, completed the EORTC CIPN 20 patient-reported instrument to evaluate chemotherapy-induced peripheral neuropathy (CIPN). Results were compared with EORTC CIPN 20 data obtained from independent study sets regarding patients receiving (1) paclitaxel, (2) combined paclitaxel and carboplatin, (3) oxaliplatin, or (4) a combination of doxorubicin and cyclophosphamide (AC). The last study set of patients on AC was selected to evaluate the use of EORTC CIPN 20 data in patients receiving chemotherapy not known to cause CIPN. Results: Cisplatin-induced neuropathy was more similar to neuropathy in patients receiving oxaliplatin than in those receiving paclitaxel. The cisplatin and oxaliplatin groups exhibited the coasting phenomenon and more prominent upper extremity symptoms than lower extremity symptoms during chemotherapy administration weeks. In contrast, paclitaxel-treated patients did not, on average, exhibit the coasting phenomenon; additionally, lower extremity symptoms were more prominent during the weeks when paclitaxel was administered. Cisplatin-induced neuropathy was less severe than was seen in patients in the other two groups, potentially because the cisplatin-receiving patients were younger. Patients receiving AC did not report substantial EORTC CIPN 20 changes. Conclusion: Understanding neuropathy similarities and differences with various chemotherapy agents may help elucidate CIPN processes and facilitate means to prevent and/or treat established CIPN.Item Controversies in the management of clinical stage 1 testis cancer(Canadian Urological Association, 2020-11) Nason, Gregory J.; Chung, Peter; Warde, Padraig; Huddart, Robert; Albers, Peter; Kollmannsberger, Christian; Booth, Christopher M.; Hansen, Aaron R.; Bedard, Philippe L.; Einhorn, Lawrence; Nichols, Craig; Rendon, Ricardo A.; Wood, Lori; Jewett, Michael A.S.; Hamilton, Robert J.; Medicine, School of MedicineIn November 2018, The Canadian Testis Cancer Workshop was convened. The two-day workshop involved urologists, medical and radiation oncologists, pathologists, radiologists, physician’s assistants, residents and fellows, nurses, patients and patient advocacy groups. One of the goals of the workshop was to discuss the challenging areas of testis cancer care where guidelines may not be specific. The objective was to distill through discussion around cases, expert approach to working through these challenges. Herein we present a summary of discussion from the workshop around controversies in the management of clinical stage 1 (CS1) disease. CS1 represents organ confined non-metastatic testis cancer that represents approximately 70-80% of men at presentation. Regardless of management, CS1 has an excellent prognosis. However, without adjuvant treatment, approximately 30% of CS1 nonseminomatous germ cell tumors (NSGCT) and 15% of CS1 seminoma relapse. The workshop reviewed that while surveillance has become the standard for the majority of patients with CS1 disease there remains debate in the management of patients at high-risk of relapse. The controversy in the management of CS1 testis cancer surrounds the optimal balance between the morbidity of overtreatment and the identification of patients who may derive most benefit from adjuvant treatment. The challenge lies in a shared decision process where discussion of options extends beyond the simple risk of relapse but to include the long-term toxicities of adjuvant treatments and the favorable cancer-specific survival.Item Long-Term Oncologic Outcomes after Primary Retroperitoneal Lymph Node Dissection: Minimizing the Need for Adjuvant Chemotherapy(AUA, 2020) Douglawi, Antoin; Calaway, Adam; Tachibana, Isamu; Barboza, Marcelo Panizzutti; Speir, Ryan; Masterson, Timothy; Adra, Nabil; Foster, Richard; Einhorn, Lawrence; Cary, Clint; Urology, School of MedicineObjective: To analyze the oncological outcomes of men undergoing primary RPLND and characterize the use of adjuvant chemotherapy and template dissections. Methods: Retrospective review of Indiana University testis cancer database identified patients who underwent a primary RPLND between 01/2007 and 12/2017. Patients and providers were contacted to obtain information regarding adjuvant therapy, recurrence, and survival. Primary outcome was recurrence-free survival (RFS). Kaplan-Meier curves assessed survival differences stratified by pathologic stage, template of dissection, and use of adjuvant chemotherapy. Results: Overall, 274 patients were included. Most men presented with CS-I disease (214, 78%). A modified unilateral template was performed in 257 (94%) and bilateral template in 17 (6%). Overall, 148 (54%) and 126 (46%) of men had Pathologic Stage I (PS-I) and PS-II disease, respectively. Thirteen patients (10%) with PS-II disease were treated with adjuvant chemotherapy. With a median follow-up was 55 months, only 33 (12%) patients recurred. Of the 113 patients with PS-II disease who did not receive chemotherapy, 21 (19%) relapsed and 81% were cured were surgery alone and never recurred. No difference in RFS was noted between modified and bilateral template dissections. Conclusions: The use of adjuvant chemotherapy has been minimal over the past decade. The majority (81%) of men with PS-II disease were cured with RPLND alone and were able to avoid chemotherapy. Modified unilateral template dissection provided excellent oncologic control while minimizing morbidity.Item Management of Chemotherapy Induced Nausea and Vomiting in Patients on Multiday Cisplatin Based Combination Chemotherapy(Hindawi, 2015-09) Ranganath, Praveen; Einhorn, Lawrence; Albany, Costantine; Medicine, School of MedicineIntroduction of cisplatin based chemotherapy has revolutionized the treatment of germ cell tumors. A common side effect of multiday cisplatin chemotherapy is severe nausea and vomiting. Considerable progress has been made in the control of these side effects since the introduction of cisplatin based chemotherapy in the 1970s. Germ cell tumor which is a model for a curable neoplasm has also turned into an excellent testing ground to develop effective strategies to prevent chemotherapy induced nausea and vomiting (CINV) in multiday cisplatin based regimens. The use of combination of a 5-hydroxytryptamine (HT)3 receptor antagonist, a neurokinin-1 (NK1) antagonist, and dexamethasone has greatly improved our ability to prevent and control acute and delayed CINV. Mechanism and pattern of CINV with multiday chemotherapy may differ from those in single day chemotherapy and therefore efficacy of antiemetic drugs as observed in single day chemotherapy may not be applicable. There are only few randomized clinical trials with special emphasis on multiday chemotherapy. Further studies are essential to determine the efficacy, optimal dose, and duration of the newer agents and combinations in multiday cisplatin based chemotherapy.Item Measurement of Patients’ Acceptable Symptom Levels and Priorities for Symptom Improvement in Advanced Lung Cancer(Springer, 2021) Krueger, Ellen; Secinti, Ekin; Wu, Wei; Hanna, Nasser; Durm, Gregory; Einhorn, Lawrence; Jalal, Shadia; Mosher, Catherine E.; Psychiatry, School of MedicinePurpose: Little research has assessed cancer patients' success criteria and priorities for symptom improvement to inform patient-centered care. Thus, we modified and tested a measure of these constructs for advanced lung cancer patients. We compared acceptable severity levels following symptom treatment across eight symptoms and identified patient subgroups based on symptom importance. Methods: Advanced lung cancer patients (N=102) completed a one-time survey, including the modified Patient-Centered Outcomes Questionnaire (PCOQ), standard symptom measures, and other clinical characteristics. Results: The modified PCOQ showed evidence of construct validity through associations with theoretically related constructs. Symptom severity and importance were moderately correlated. Levels of acceptable symptom severity were low and did not differ across the eight symptoms. Four patient subgroups were identified: (1) those who rated all symptoms as low in importance (n=12); (2) those who rated bronchial symptoms and sleep problems as low in importance and all other symptoms as moderately important (n=29); (3) those who rated nausea and emotional distress as low in importance and all other symptoms as moderately important (n=23); and (4) those who rated all symptoms as highly important (n=33). Subgroups were unrelated to clinical characteristics, except for functional status. Conclusion: The modified PCOQ showed evidence of construct validity. Patients considered low symptom severity to be acceptable, irrespective of the symptom. Findings suggest that symptom severity and importance are related yet distinct aspects of the advanced lung cancer symptom experience. Patients have heterogeneous priorities for symptom improvement, which has implications for tailoring treatment.Item Ototoxicity After Cisplatin-Based Chemotherapy: Factors Associated With Discrepancies Between Patient-Reported Outcomes and Audiometric Assessments(Wolters Kluwer, 2022) Ardeshirrouhanifard, Shirin; Fossa, Sophie D.; Huddart, Robert; Monahan, Patrick O.; Fung, Chunkit; Song, Yiqing; Dolan, M. Eileen; Feldman, Darren R.; Hamilton, Robert J.; Vaughn, David; Martin, Neil E.; Kollmannsberger, Christian; Dinh, Paul; Einhorn, Lawrence; Frisina, Robert D.; Travis, Lois B.; The Platinum Study Group; Biostatistics and Health Data Science, School of MedicineObjectives: To provide new information on factors associated with discrepancies between patient-reported and audiometrically defined hearing loss (HL) in adult-onset cancer survivors after cisplatin-based chemotherapy (CBCT) and to comprehensively investigate risk factors associated with audiometrically defined HL. Design: A total of 1410 testicular cancer survivors (TCS) ≥6 months post-CBCT underwent comprehensive audiometric assessments (0.25 to 12 kHz) and completed questionnaires. HL severity was defined using American Speech-Language-Hearing Association criteria. Multivariable multinomial regression identified factors associated with discrepancies between patient-reported and audiometrically defined HL and multivariable ordinal regression evaluated factors associated with the latter. Results: Overall, 34.8% of TCS self-reported HL. Among TCS without tinnitus, those with audiometrically defined HL at only extended high frequencies (EHFs) (10 to 12 kHz) (17.8%) or at both EHFs and standard frequencies (0.25 to 8 kHz) (23.4%) were significantly more likely to self-report HL than those with no audiometrically defined HL (8.1%) [odds ratio (OR) = 2.48; 95% confidence interval (CI), 1.31 to 4.68; and OR = 3.49; 95% CI, 1.89 to 6.44, respectively]. Older age (OR = 1.09; 95% CI, 1.07 to 1.11, p < 0.0001), absence of prior noise exposure (OR = 1.40; 95% CI, 1.06 to 1.84, p = 0.02), mixed/conductive HL (OR = 2.01; 95% CI, 1.34 to 3.02, p = 0.0007), no hearing aid use (OR = 5.64; 95% CI, 1.84 to 17.32, p = 0.003), and lower education (OR = 2.12; 95% CI, 1.23 to 3.67, p = 0.007 for high school or less education versus postgraduate education) were associated with greater underestimation of audiometrically defined HL severity, while tinnitus was associated with greater overestimation (OR = 4.65; 95% CI, 2.64 to 8.20 for a little tinnitus, OR = 5.87; 95% CI, 2.65 to 13.04 for quite a bit tinnitus, and OR = 10.57; 95% CI, 4.91 to 22.79 for very much tinnitus p < 0.0001). Older age (OR = 1.13; 95% CI, 1.12 to 1.15, p < 0.0001), cumulative cisplatin dose (>300 mg/m2, OR = 1.47; 95% CI, 1.21 to 1.80, p = 0.0001), and hypertension (OR = 1.80; 95% CI, 1.28 to 2.52, p = 0.0007) were associated with greater American Speech-Language-Hearing Association-defined HL severity, whereas postgraduate education (OR = 0.58; 95% CI, 0.40 to 0.85, p = 0.005) was associated with less severe HL. Conclusions: Discrepancies between patient-reported and audiometrically defined HL after CBCT are due to several factors. For survivors who self-report HL but have normal audiometric findings at standard frequencies, referral to an audiologist for additional testing and inclusion of EHFs in audiometric assessments should be considered.Item A phase 2, open-label study of brentuximab vedotin in patients with CD30-expressing solid tumors(Springer Nature, 2019-08) Sharman, Jeffrey P.; Wheler, Jennifer J.; Einhorn, Lawrence; Dowlati, Afshin; Shapiro, Geoffrey I.; Hilton, John; Burke, John M.; Siddiqi, Tanya; Whiting, Nancy; Jalal, Shadia I.; Medicine, School of MedicinePurpose Brentuximab vedotin (BV) is an anti-CD30 antibody-drug conjugate used in the treatment of several types of lymphomas. Expression of the target antigen has also been reported on a variety of malignant tumors of nonlymphoid origin. This phase 2, open-label study evaluated the safety and antitumor activity of BV in patients with CD30-expressing nonlymphomatous malignancies. Methods Patients were dosed with 1.8 or 2.4 mg/kg BV once every three weeks. Antitumor activity was assessed at Cycles 2, 4, and every 4 cycles thereafter. Patients with stable disease or better were eligible to continue treatment until disease progression, unacceptable toxicity, or study closure. Results Of the 2693 patients screened, 3.8% had solid tumors with CD30 expression and 63 eligible patients with solid tumors enrolled in this study. The most common CD30 positive solid tumors were testicular cancer and mesothelioma. Both subtypes had more than one patient with an objective response. The median duration of BV exposure was 6.1 weeks. The disease control rate, defined as achieving stable disease or better at any point during the study, was 55%. The objective response rate was 11%, with a median duration of response of 2.92 months. The most common adverse events reported were fatigue (57%), nausea (33%), and decreased appetite (32%). Conclusion The safety profile of BV in patients with solid tumors was similar to the known safety profile of BV. In solid tumors, BV had modest activity as a single agent, which was similar to other second-line treatments already available to patients.Item Relations of perceived injustice to psycho-spiritual outcomes in advanced lung and prostate cancer: Examining the role of acceptance and meaning making(Wiley, 2022-12) Secinti, Ekin; Wu, Wei; Krueger, Ellen F.; Hirsh, Adam T.; Torke, Alexia M.; Hanna, Nasser H.; Adra, Nabil; Durm, Gregory A.; Einhorn, Lawrence; Pili, Roberto; Jalal, Shadia I.; Mosher, Catherine E.; Psychology, School of ScienceObjective: Many advanced cancer patients struggle with anxiety, depressive symptoms, and anger toward God and illness-related stressors. Patients may perceive their illness as an injustice (i.e., appraise their illness as unfair, severe, and irreparable or blame others for their illness), which may be a risk factor for poor psychological and spiritual outcomes. This study examined relations between cancer-related perceived injustice and psycho-spiritual outcomes as well as potential mediators of these relationships. Methods: Advanced lung (n=102) and prostate (n=99) cancer patients completed a one-time survey. Using path analyses, we examined a parallel mediation model including the direct effects of perceived injustice on psycho-spiritual outcomes (i.e., anxiety, depressive symptoms, anger about cancer, anger towards God) and the indirect effects of perceived injustice on psycho-spiritual outcomes through two parallel mediators: meaning making and acceptance of cancer. We then explored whether these relations differed by cancer type. Results: Path analyses indicated that perceived injustice was directly and indirectly – through acceptance of cancer but not meaning making – associated with psycho-spiritual outcomes. Results did not differ between lung and prostate cancer patients. Conclusions: Advanced cancer patients with greater perceived injustice are at higher risk for poor psycho-spiritual outcomes. Acceptance of cancer, but not meaning making, explained relationships between cancer-related perceived injustice and psycho-spiritual outcomes. Findings support testing acceptance-based interventions to address perceived injustice in advanced cancer patients.
