Metastatic Burden

<b><i>Background:</i></b> The value of baseline fluorodeoxyglucose-positron emission tomography-computed tomography (PET-CT) remains uncertain once gastroesophageal cancer is metastatic. We hypothesized that assessment of detailed PET-CT parameters (maximum standardized uptake value [SUVmax] and/or total lesion glycolysis [TLG]), and the extent of metastatic burden could aid prediction of probability of response or prognosticate. <b><i>Methods:</i></b> We retrospectively analyzed treatment-naive patients with stage 4 gastroesophageal cancer (December 2002–August 2017) who had initial PET-CT for cancer staging at MD Anderson Cancer Center. SUVmax and TLG were compared with treatment outcomes for the full cohort and subgroups based on metastatic burden (≤2 or &#x3e;2 metastatic sites). <b><i>Results:</i></b> We identified 129 patients with metastatic gastroesophageal cancer who underwent PET-CT before first-line therapy. The median follow-up time was 61 months. The median overall survival (OS) was 18.5 months; the first progression-free survival (PFS) was 5.5 months. SUVmax or TLG of the primary tumor or of all metastases combined had no influence on OS or PFS, whether the number of metastases was ≤2 or &#x3e;2. Overall response rates (ORRs) to first-line therapy were 48% and 45% for patients with ≤2 and &#x3e;2 metastases, respectively (nonsignificant). ORR did not differ based on low or high values of SUVmax or TLG. <b><i>Conclusions:</i></b> This is the first assessment of a unique set of PET-CT data and its association with outcomes in metastatic gastroesophageal cancer. In our large cohort of patients, detailed analyses of PET-CT (by SUVmax and/or TLG) did not discriminate any parameters examined. Thus, baseline PET-CT in untreated metastatic gastroesophageal cancer patients has limited or no utility.

Purpose To assess the cost effectiveness of fluorine-18–fluorodeoxyglucose positron emission tomography (FDG-PET) in patients with Hodgkin's lymphoma (HL) with unconfirmed complete remission (CRu) or partial remission (PR) after first-line treatment. Patients and Methods One hundred thirty patients with HL were prospectively studied. After treatment, all patients with CRu/PR were evaluated with FDG-PET. In addition, PET-negative patients were evaluated with standard follow-up, and PET-positive patients were evaluated with biopsies of the positive lesions. Local unit costs of procedures and tests were evaluated. Cost effectiveness was determined by evaluating projected annual economic impact of strategies without and with FDG-PET on HL management. Results After treatment, CRu/PR was observed in 50 (40.0%) of the 127 patients; the sensitivity, specificity, and positive and negative predictive values of FDG-PET were 100%, 92.0%, 92.3%, and 100%, respectively (accuracy of 95.9%). Local restaging costs without PET were $350,050 compared with $283,262 with PET, a 19% decrease. The incremental cost-effectiveness ratio is −$3,268 to detect one true case. PET costs represented 1% of total costs of HL treatment. Simulated costs in the 974 patients registered in the 2008 Brazilian public health care database showed that the strategy including restaging PET would have a total program cost of $56,498,314, which is $516,942 less than without restaging PET, resulting in a 1% cost saving. Conclusion FDG-PET demonstrated 95.9% accuracy in restaging for patients with HL with CRu/PR after first-line therapy. Given the observed probabilities, FDG-PET is highly cost effective and would reduce costs for the public health care program in Brazil.

PURPOSE The AHL2011 study (ClinicalTrials.gov identifier: NCT01358747 ) demonstrated that a positron emission tomography (PET)-driven de-escalation strategy after two cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) provides similar progression-free survival (PFS) and overall survival (OS) and reduces early toxicity compared with a nonmonitored standard treatment. Here, we report, with a prolonged follow-up, the final study results. METHODS Patients with advanced Hodgkin lymphoma (stage III, IV, or IIB with mediastinum/thorax ratio > 0.33 or extranodal involvement) age 16-60 years were prospectively randomly assigned between 6 × BEACOPP and a PET-driven arm after 2 × BEACOPP delivering 4 × ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) in PET2– and 4 × BEACOPP in PET2+ patients. PET performed after four cycles of chemotherapy had to be negative to complete the planned treatment. RESULTS In total, 823 patients were enrolled including 413 in the standard arm and 410 in the PET-driven arm. With a 67.2-month median follow-up, 5-year PFS (87.5% v 86.7%; hazard ratio [HR] = 1.07; 95% CI, 0.74 to 1.57; P = .67) and OS (97.7% in both arms; HR = 1.012; 95% CI, 0.50 to 2.10; P = .53) were similar in both randomization arms. In the whole cohort, full interim PET assessment predicted patients' 5-year PFS (92.3% in PET2–/PET4–, 75.4% [HR = 3.26; 95% CI, 18.3 to 5.77] in PET2+/PET4– and 46.5% [HR = 12.4; 95% CI, 7.31 to 19.51] in PET4+ patients, respectively; P < .0001) independent of international prognosis score. Five-year OS was also affected by interim PET results, and PET2+/PET4– patients (93.5%; HR = 3.3; 95% CI, 1.07 to 10.1; P = .036) and PET4+ patients (91.9%; HR = 3.756; 95% CI, 1.07 to 13.18; P = .038) had a significant lower OS than PET2–/PET4– patients (98.2%). Twenty-two patients (2.7%) developed a second primary malignancy, 13 (3.2%) and 9 (2.2%) in the standard and experimental arms, respectively. CONCLUSION The extended follow-up confirms the continued efficacy and favorable safety of AHL2011 PET-driven strategy, which is noninferior to standard six cycles of BEACOPP. PET4 provides additional prognostic information to PET2 and allows identifying patients with particularly poor prognosis.

Abstract Abstract 335 The cure of relapsed or refractory Hodgkin Lymphoma (HL) still remains a challenge. High dose chemotherapy followed by autologous stem cell transplantation (ASCT) is the standard of care but almost half of patients relapse after ASCT and have poor outcome. Predictive factors including an interval from end of first line therapy to relapse shorter than 12 months, an Ann-Arbor stage III or IV at relapse, and relapse in previously irradiated field are currently used to identify patients with poor outcome. Development of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) assessment improves evaluation of response both in first line and salvage treatments. The aim of our study is first to confirm the predictive value of PET status before ASCT and then to compare ASCT strategy (single versus tandem) in patients with relapsed and/or refractory HL. We here report a series of 111 consecutive patients with relapsed and/or refractory HL who achieved at least partial remission (PR) at PET evaluation after one line of salvage chemotherapy and who underwent single or tandem ASCT. PET response assessment showed 85 (77%) patients in CR (PET- group) and 26 (23%) in PR (PET+ group). Five-year overall (OS) and progression free survival (PFS) were 81% and 64% respectively. There were significant differences in 5-year PFS (79% versus 23%, p<0.001) and 5-year OS (90% versus 55%, p=0.001) between PET- and PET+ groups respectively. This predictive value remained significant in both favorable/intermediate and unfavorable subgroups. In PET+ subgroup analysis, tandem ASCT dramatically improved 5-years PFS, from 0% to 43% (p=0.034) compared to single ASCT. Multivariate analysis showed that PET status (HR: 5.26 [2.57–10.73]) and tandem ASCT (HR: 0.39 [0.19–0.78]) but not relapse risk (HR: 1.77 [0.80–3.92]) significantly influenced PFS, while only PET status significantly influenced OS (HR: 4.03 [1.38–11.75]). Our results suggest that I) PET status before ASCT must be considered as a strong and significant prognostic factor influencing outcome and identifying high risk patients for more intensive strategy II) Tandem ASCT improved outcome compared to single ASCT, especially for PET+ patients.
