The association between radiological response and overall survival (OS) was retrospectively evaluated in patients treated with lenvatinib as a first-line systemic treatment for unresectable hepatocellular carcinoma. A total of 182 patients with Child–Pugh class A liver function and an Eastern Cooperative Oncology Group performance status of zero or one were enrolled. Radiological evaluation was performed using Response Evaluation Criteria in Solid Tumors (RECIST) and modified Response Evaluation Criteria in Solid Tumors (mRECIST). Initial radiological evaluation confirmed significant stratification of OS by efficacy judgment with both RECIST and mRECIST, and that initial radiological response was an independent prognostic factor for OS on multivariate analysis. Furthermore, in patients with stable disease (SD) at initial evaluation, macrovascular invasion at the initial evaluation on RECIST and modified albumin–bilirubin grade at initial evaluation on mRECIST were independent predictors of OS on multivariate analysis. In conclusion, if objective response is obtained at the initial evaluation, continuation of treatment appears desirable because prolonged OS can be expected; but, if SD is obtained at the initial evaluation, one should determine whether to continue or switch to the next treatment, with careful consideration of factors related to the tumor and hepatic reserve at the initial evaluation.

Tumor response and disease progression are assessed using imaging technologies. However, these technologies fail to detect tumor responses at the molecular level and clonal evolution. A potential surrogate for such parameters is using circulating tumor DNA (ctDNA). This study aimed to examine the quantity and composition of the ctDNA results of 29 cancer patients before and after dendritic cell (DC) immunotherapy and develop criteria to evaluate the molecular response to treatment based on these results. We categorized the patients into four categories based on percent changes in the total ctDNA compared with the baseline ctDNA titers, and this response assessment was termed genomic response evaluation criteria in solid tumors or gRECIST. Even those who are clinically evaluated as having a good response might harbor unfavorable tumor responses at the molecular level. Newly formed ctDNA levels can be the most prognostic parameter in tumor progression or the treatment response, while ctDNA clearance and the decline or rise in existing ctDNA did not change significantly in genomic response categories (gRECIST). More research is needed to support the clinical use of ctDNA in precision oncology and personalized cancer treatment.

Immune response evaluation criteria in solid tumors (iRECIST) is recommended during immune checkpoint inhibitors (ICIs) treatment, due to the possibility of pseudoprogression. We evaluated the frequency of pseudoprogression in hepatocellular carcinoma (HCC) patients. This retrospective multicenter study involved 158 consecutive patients who underwent nivolumab treatment for HCC in Korea. At the initial evaluation, 94 patients presented with immune unconfirmed progressive disease, and 22 continued nivolumab. At the second evaluation, 21 of the 22 patients (95.5%) had confirmed progression and no pseudoprogression was observed. Considering low possibility of pseudoprogression, iRECIST may not be required for HCC.

Ziel Die Chemosaturation mittels perkutaner hepatischer Perfusion mit Melphalan (CS-PHP) ist ein palliatives Therapieverfahren für Patienten mit nicht kurativ behandelbaren Lebertumoren. Die CS-PHP erlaubt eine selektive intrahepatische Anreicherung von hochdosiertem Melphalan bei minimaler systemischer Toxizität durch venöse Hämofiltration. Ziel dieser Studie war es, das Ansprechen und Überleben sowie die Sicherheit der CS-PHP-Prozedur bei Patienten mit leberdominant metastasiertem Aderhautmelanom zu evaluieren. Material und Methoden Gesamtansprechrate (overall response rate, ORR) und Krankheitskontrollrate (disease control rate, DCR) wurden anhand von Response Evaluation Criteria In Solid Tumors (RECIST1.1) ermittelt. Medianes Gesamtüberleben (mOS), medianes progressionsfreies Überleben (mPFS) und hepatisches mPFS (mhPFS) wurden mittels Kaplan-Meier-Schätzer ermittelt. Nebenwirkungen wurden entsprechend der einheitlichen Terminologie-Kriterien für Nebenwirkungen (CTCAE) v5 klassifiziert. Ergebnisse 30 Patienten wurden zwischen Oktober 2014 und Januar 2019 mit 70 Chemosaturationen behandelt. Die ORR betrug 42,3 % und die DCR 80,8 %. Das mOS betrug 12 (95 %-Konfidenzintervall (KI) 7–15) Monate, das mPFS 6 (95 %-KI 4–10) und das mhPFS ebenfalls 6 (95 %-KI 4–13) Monate. Signifikante, aber transiente hämatotoxische Nebenwirkungen waren häufig (87 % Grad-3/4-Thrombozytopenie), hepatische Toxizität bis Leberversagen (n = 1/70) sowie kardiovaskuläre Komplikationen (ischämischer Insult, n = 1/70) waren selten. Schlussfolgerung Das palliative Therapiekonzept der Chemosaturation ist bei Patienten mit hepatisch metastasiertem Aderhautmelanom effektiv. Die interventionelle Prozedur ist sicher, seltene, aber schwerwiegende kardiovaskuläre und hepatische Komplikationen erfordern eine sorgfältige Patientenselektion und intensive Aufmerksamkeit.

Abstract Background Evaluating the effect on primary lesions is important in determining treatment strategies for esophageal cancer. The Response Evaluation Criteria in Solid Tumors system, which employs the longest diameter for measuring tumors, is commonly used for evaluating treatment effects. However, the usefulness of these criteria in assessing primary esophageal tumors remains controversial. Thus, we evaluated this issue by measuring not only the longest diameter but also the shorter axis of the tumor. Methods We retrospectively reviewed data from 313 patients with esophageal cancer treated with neoadjuvant chemotherapy followed by esophagectomy at three major high-volume centers in Japan. All patients underwent contrast-enhanced computed tomography before and after chemotherapy. The longest and shortest tumor diameters were measured in each case. Treatment effects were adapted to the Response Evaluation Criteria in Solid Tumors system. Correlations between pathological and survival data were also analyzed. Results Inter-observer discrepancies were examined for changes in the longest diameter and shorter axis of the tumor (the intraclass correlation coefficients were 0.550 and 0.624, respectively). The shorter axis was correlated with the pathological response in the multivariate analysis (p < 0.001). The shorter axis was significantly associated with overall survival and disease-free survival (both p < 0.001), whereas this association was not observed for the longest tumor diameter. Conclusions This multicenter study demonstrated that the Response Evaluation Criteria in Solid Tumors system is useful for predicting pathological response and survival by incorporating the shorter axis of the primary esophageal tumor.
