Soluble mesothelin-related peptides (SMRP) are a potential tumor marker for malignant mesothelioma. The aim of this study was to determine the differences in SMRP levels in patients with malignant mesothelioma before treatment and in various responses to treatment and to investigate whether SMRP level could be useful in evaluating tumor response to treatment. The study included patients with malignant mesothelioma treated at the Institute of Oncology Ljubljana between March 2007 and December 2009. Blood samples were collected before treatment and/or in various responses to treatment. SMRP levels were determined using ELISA assay based upon a combination of two monoclonal antibodies. Mann-Whitney test was used to determine the differences in SMRP levels in various responses to treatment.Median SMRP was 2.80 nmol/L (range 0.00–34.80) before treatment, 0.00 nmol/L (range 0.00–0.00) in complete response, 0.48 nmol/L (range 0.00–4.40) in partial response, 1.65 nmol/L (range 0.00–20.71) in stable disease and 7.15 nmol/L (range 0.44–31.56) in progressive disease. Pre-treatment SMRP levels were significantly higher than in stable disease, partial response and complete response (p=0.006), as were SMRP levels in progressive disease compared to stable disease, partial response and complete response (p= 0.006), as were SMRP levels in progressive disease compared to stable disease, partial response and complete response (p< 0.001).Our findings suggest that SMRP may be a useful tumor marker for detecting the progression of malignant mesothelioma and evaluating tumor response to treatment.

BackgroundWe present a radiomics-based model for predicting response to pembrolizumab in patients with advanced rare cancers.MethodsThe study included 57 patients with advanced rare cancers who were enrolled in our phase II clinical trial of pembrolizumab. Tumor response was evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and immune-related RECIST (irRECIST). Patients were categorized as 20 “controlled disease” (stable disease, partial response, or complete response) or 37 progressive disease). We used 3D-slicer to segment target lesions on standard-of-care, pretreatment contrast enhanced CT scans. We extracted 610 features (10 histogram-based features and 600 second-order texture features) from each volume of interest. Least absolute shrinkage and selection operator logistic regression was used to detect the most discriminatory features. Selected features were used to create a classification model, using XGBoost, for the prediction of tumor response to pembrolizumab. Leave-one-out cross-validation was performed to assess model performance.FindingsThe 10 most relevant radiomics features were selected; XGBoost-based classification successfully differentiated between controlled disease (complete response, partial response, stable disease) and progressive disease with high accuracy, sensitivity, and specificity in patients assessed by RECIST (94.7%, 97.3%, and 90%, respectively; p<0.001) and in patients assessed by irRECIST (94.7%, 93.9%, and 95.8%, respectively; p<0.001). Additionally, the common features of the RECIST and irRECIST groups also highly predicted pembrolizumab response with accuracy, sensitivity, specificity, and p value of 94.7%, 97%, 90%, p<0.001% and 96%, 96%, 95%, p<0.001, respectively.ConclusionOur radiomics-based signature identified imaging differences that predicted pembrolizumab response in patients with advanced rare cancer.InterpretationOur radiomics-based signature identified imaging differences that predicted pembrolizumab response in patients with advanced rare cancer.

AbstractBackground.Fibulin-3 is a new potential biomarker for malignant mesothelioma (MM). This study evaluated the potential applicability of fibulin-3 plasma levels as a biomarker of response to treatment and its prognostic value for progressive disease within 18 months. The potential applicability of fibulin-3 in comparison with or in addition to soluble mesothelin-related peptides (SMRP) was also assessed.Patients and methods.The study included 78 MM patients treated at the Institute of Oncology Ljubljana between 2007 and 2011. Fibulin-3 levels in plasma samples obtained before treatment and in various responses to treatment were measured with the enzyme-linked immunosorbent assay.Results.In patients evaluated before the treatment, fibulin-3 levels were not influenced by histopathological sub-types, tumour stages or the presence of metastatic disease. Significantly higher fibulin-3 levels were found in progressive disease as compared to the levels before treatment (Mann-Whitney [U] test = 472.50, p = 0.003), in complete response to treatment (U = 42.00, p = 0.010), and in stable disease (U = 542.00, p = 0.001). Patients with fibulin-3 levels exceeding 34.25 ng/ml before treatment had more than four times higher probability for developing progressive disease within 18 months (odds ratio [OR] = 4.35, 95% confidence interval [CI] 1.56–12.13). Additionally, patients with fibulin-3 levels above 34.25 ng/ml after treatment with complete response or stable disease had increased odds for progressive disease within 18 months (OR = 6.94, 95% CI 0.99–48.55 and OR = 4.39, 95% CI 1.63–11.81, respectively).Conclusions.Our findings suggest that in addition to SMRP fibulin-3 could also be helpful in detecting the progression of MM.

The Impact

Soft tissue sarcomas are a rare type of cancer generally treated with palliative chemotherapy when in the advanced stage. There is a lack of published health utility data for locally advanced “inoperable”/metastatic disease (ASTS), essential for calculating the cost-effectiveness of current and future treatments. This study estimated time trade-off (TTO) and standard gamble (SG) preference values associated with four ASTS health states (progressive disease, stable disease, partial response, complete response) among members of the general public in the UK (n=207). The four health states were associated with decreases in preference values from full health. Complete response was the most preferred health state (mean utility of 0.60 using TTO). The second most preferred health state was partial response followed by stable disease (mean utilities were 0.51 and 0.43, respectively, using TTO). The least preferred health state was progressive disease (mean utility of 0.30 using TTO). The utility value for each state was significantly different from one another (P<0.001). This study demonstrated and quantified the impact that different treatment responses may have on the health-related quality of life of patients with ASTS.

Abstract Abstract 1978 In 2005, a NIH consensus conference was held to better define methods for research in chronic GVHD (cGVHD). Provisional definitions of response categories for individual organs and overall cGVHD disease activity were proposed: complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). These response criteria were designed to improve consistency in documentation of disease activity across different centers, to allow less biased response assessments by comparison of enrollment and follow-up measures, rather than relying on clinician perceptions of change in the setting of clinical trials. In this study, we compared the proposed response criteria with clinician-reported changes in organ specific and overall responses. Good agreement would suggest that the proposed response criteria mirror clinician judgments of whether patients are responding to treatment or not. Methods: Patients ≥ 2 years of age diagnosed with cGVHD requiring systemic treatment ≤ 3 years after transplantation were eligible and assessed every 3–6 months. At each visit, clinicians reported the following: organ specific measures (used to calculate the NIH organ response for skin, mouth, eye and overall), perception of change in organ and overall involvement (completely gone = CR; very much or moderately improved = PR; a little better, stable, or a little worse = SD; or moderately or very much worse = PD), and overall aggregate response (CR, PR, SD, PD). Kappa statistics were used to compare agreement between these measures, with 0.21–0.4 considered fair agreement. Results: As of September 2010, 290 patients who had at least one follow-up visit 3 or 6 months beyond enrollment were included, with median age of 51 years (2–79). Based on NIH overall response criteria, 24 (8%) had CR, 83 (29%) had PR, 25 (9%) had SD, and 158 (54%) had PD for an overall CR+PR of 37%. In contrast, clinicians reported that 31 (11%) had CR, 171 (59%) had PR, 30 (10%) had SD and 56 (19%) had PD for an overall CR+PR of 70%. For organ specific comparisons, agreement rates between NIH proposed response measures and clinician reported changes in skin, mouth and eye were fair. For overall response, agreement rates between the calculated NIH response and clinician-reported overall change and clinician-reported response status were also fair. (Table) Conclusions: For both organ-specific and overall comparisons, the proposed NIH response criteria do not agree well with responses determined by clinicians. These data suggest that conclusions from prior literature reporting high overall CR+PR rates based on clinician judgment would not be supported if the current NIH response criteria had been used to measure response. Additional studies are needed to validate candidate response criteria through correlation with a robust, objective and informative gold standard.Table.Calculated NIH and clinician reported response rates in specific organs and overallOrganResponse measureNNICRPRSDPDKappa with NIH responseSkinCalculated NIH skin response28635%22%7%15%21%Clinician reported skin change28629%17%17%32%5%0.39*/0.43**MouthCalculated NIH mouth response28720%15%7%45%13%Clinician reported mouth change28720%15%29%33%4%0.28*/0.35**EyeCalculated NIH eye response16840%10%4%26%19%Clinician reported eye change16844%2%10%39%5%0.29*/0.26**OverallCalculated NIH overall response288—8%29%9%54%Clinician reported overall change285—7%41%45%8%0.24**Clinician reported response status288—11%59%10%19%0.20**NI, not involved; CR, complete response/completely resolved; PR, partial response/moderately better, very much better; SD, stable disease/a little better/stable/a little worse; PD, progressive disease/moderately worse, very much worse*simple kappa, including all patients**weighted kappa, limited to patients with involvement by both measures at enrollment Disclosures: No relevant conflicts of interest to declare.

Background: Pancreatic adenocarcinoma has a poor prognosis, resulting in a <10% survival rate at 5 years. Modulated electro-hyperthermia (mEHT) has been increasingly used for pancreatic cancer palliative care and therapy. Objective: To monitor the efficacy and safety of mEHT for the treatment of advanced pancreatic cancer. Methods: We collected data retrospectively on 106 patients affected by stage III-IV pancreatic adenocarcinoma. They were divided into 2 groups: patients who did not receive mEHT (no-mEHT) and patients who were treated with mEHT. We performed mEHT applying a power of 60 to 150 W for 40 to 90 minutes. The mEHT treatment was associated with chemotherapy and/or radiotherapy for 33 (84.6%) patients, whereas 6 (15.4%) patients received mEHT alone. The patients of the no-mEHT group received chemotherapy and/or radiotherapy in 55.2% of cases. Results: Median age of the sample was 65.3 years (range = 31-80 years). After 3 months of therapy, the mEHT group had partial response in 22/34 patients (64.7%), stable disease in 10/34 patients (29.4%), and progressive disease in 2/34 patients (8.3%). The no-mEHT group had partial response in 3/36 patients (8.3%), stable disease in 10/36 patients (27.8%), and progressive disease in 23/36 patients (34.3%). The median overall survival of the mEHT group was 18.0 months (range = 1.5-68.0 months) and 10.9 months (range = 0.4-55.4 months) for the non-mEHT group. Conclusions: mEHT may improve tumor response and survival of pancreatic cancer patients.

19 Background: Circulating tumor cells (CTCs) measured by the CellSearch system in metastatic breast cancer have been reported to correlate with the response to chemotherapy. The purpose of this study was to clarify the clinicopathologic characteristics of CTCs in patients with advanced or recurrent esophageal cancer. Methods: CTCs from 35 patients with advanced or recurrent esophageal cancer were measured by this system before initiation of a new line of therapy and more than 3 weeks after initiation of therapy. Correlation between CTC counts and clinicopathologic variables was examined. Results: Of the 35 patients, 14 patients (40%) had recurrent esophageal cancer and 21 patients (60%) had primary advanced esophageal cancer. Their mean age was 65 years (range, 43 to 89 ). Of the 14 patients with recurrent esophageal cancer, measurable lesions included metastasis to lymph nodes, kidney metastasis, liver metastasis, and lung metastasis. With regard to their therapeutic effect, 1 patient (3%) obtained a complete response, 14 (40%) had a partial response, 9 (26%) had stable disease, 11 (31%) had progressive disease. Of the 15 patients with complete response and partial response, the number of CTCs diminished in 8 patients (53%). Of the 20 patients with stable disease and progressive disease, the number of CTCs increased in 16 patients (80%). The change in CTCs tended to correlate with disease progression and chemotherapeutic effect (P=0.07). The survival of patients with >3 CTCs was shorter than that of patients with <3 CTCs both before initiation of a new line of therapy (P=0.026) and more than 3 weeks after initiation of therapy (P=0.003). Conclusions: This study suggests that measurement of CTCs in advanced or recurrent esophageal cancer patients could be useful as a tool for predicting patients’ survival and monitoring response to cancer therapy.

ObjectiveVaginal metastases are very rare events with a poor prognosis. To improve the quality of life, local treatments should be considered. The aim of this study was to evaluate the role of electrochemotherapy as palliative treatment in vaginal cancer not amenable to standard treatments due to poor performance status, previous treatments, or advanced disease.MethodsThis is a prospective observational study on patients diagnosed with vaginal cancer and treated from January 2017 to December 2018 with palliative electrochemotherapy. We collected data on patients with vaginal cancer treated by electrochemotherapy with the aim of local control. Data regarding electrochemotherapy, hospital stay, adverse events, and patient outcomes were analyzed. Intravenous bleomycin was injected as a bolus in 2–3 min at a dose of 15 000 UI/m2 and electrical pulses started 8 min after chemotherapy. Electrochemotherapy response was defined according to the Response Evaluation Criteria in Solid Tumors.ResultsFive patients with vaginal recurrence (two squamous, two melanomas, and one leiomyosarcoma) and one with vaginal metastasis from intestinal adenocarcinoma received one treatment and two patients were re-treated. Imaging reported nodal metastasis (inguinal or pelvic) in two patients, distant metastases in two, and both node and distant metastasis in two patients, respectively. Response Evaluation Criteria in Solid Tumors showed a complete response in one patient, partial response in three patients, stable disease in one patient, and progressive disease in one patient, with an overall response rate of 67% and a clinical benefit rate (complete response, partial response, stable disease) of 83%. Two patients were re-treated and had a new response (partial response and stable disease, respectively). At last follow-up, two patients had died of the disease, two were alive with stable disease, one was alive with progressive disease, and one was alive without disease. Median post-electrochemotherapy overall survival was 12.9 months (range 1.6–26.9) and 1-year overall survival was 66.7%.ConclusionsThis preliminary experience showed a tumor response or stabilization in 83% of patients requiring palliative management for vaginal cancer. Further studies are needed to evaluate treatment outcome in larger and prospective series.

Abstract Second autologous stem cell transplant (ASCT) is a treatment option for multiple myeloma (MM) patients (pts) who have disease progression after first ASCT. About 20% of MM pts have evidence of renal dysfunction and many more develop it subsequently. Outcomes of second ASCT in pts with renal dysfunction have not been described. We identified 18 pts at our institution who underwent a second ASCT for relapsed MM and had evidence of renal dysfunction (creatinine clearance ≤ 60ml/min/1.73m2). Pts who underwent a planned tandem transplant were excluded from this analysis. Patient characteristics are shown in Table 1. The median age of pts was 61 years (range, 49-72). The median time between first and second ASCT was 49.8 months (range, 19.2-81.9). Ten pts received one chemotherapy regimen while nine pts received two or more chemotherapy regimens between first and second ASCT. The chemotherapy regimens used between first and second transplant included IMid based (n=6), proteosome inhibitor based (n=3) and combination of both (n=9). Approximately half of the pts had progressive disease at the time of second ASCT. Median creatinine clearance at the time of second ASCT was 43.5 ml/min//1.73m2. All pts received G-CSF 5µg/Kg from day + 6 till absolute neutrophil count was ≥1500/µL, norfloxacin, acyclovir and fluconazole were used for antimicrobial prophylaxis during the hospitalization. One pt was dialysis dependent. Patients received a median dose of melphalan of 140mg/m2 (range 100-200 mg/m2). Median follow up post second ASCT was 17.1 months (range, 2.4- 100). One pt died 74 days after the transplant due to multi- organ failure. Disease status at day 100 post ASCT is shown in Table 2. Thirteen of 17 pts had a partial response or better after second ASCT. Of 17 evaluable pts at day 100, twelve had an upgrade from the disease response category achieved with the last regimen used prior to second ASCT while five pts had stable disease response. Three pts received maintenance therapy after the second ASCT with bortezomib(n=2) and lenalidomide (n=1). Figures 1 and 2 show the overall survival (OS) and relapse free survival (RFS). Median RFS was 22.2 months and median OS was 27 months. The outcomes of patients with renal dysfunction who underwent ASCT in the era of novel agents at our institution are comparable to those reported for second ASCT. The transplant related mortality was not higher than expected and the median PFS of about 2 years makes the option of second ASCT in this group of patients a valuable treatment modality. The utility of maintenance therapy after the second ASCT is not established, but may have contributed to the durable responses seen in some pts assessed herein and deserves to be investigated further.

Introduction Multimodality therapy has become the standard treatment for patients with locally advanced (T3 and T4) rectal carcinoma. Accurate preoperative staging of the patients with rectal cancer has increased in importance because the selection of patients with transmural rectal cancer (T3 or T4) or node-positive disease leads to a previous nonsurgical neoadjuvant treatment. The purpose of this study was to evaluate the predictive value of the clinical response to neoadjuvant therapy on the basis of pathological results obtained on rectal cancer patients treated by chemoradiotherapy and surgery. Methods From 1994 to 2003, 58 patients with a primary diagnosis of rectal cancer were studied at our department and enrolled in a neoadjuvant protocol of chemoradiotherapy followed by surgery. All patients were treated by 30 days of chemoradiotherapy. At the end of the chemoradiotherapy, each patient underwent clinical examination, including digital rectal examination, proctoscopy and abdominal-pelvic computerized tomography to define the clinical response to the chemoradiotherapy. Surgical resection was performed in all patients three weeks after the end of chemoradiotherapy, and histological analysis was performed on all resected specimens. Results The clinical complete response rate corresponded to the pathological complete response rate, whereas the clinical evaluation overestimated partial response and stable disease. The pathologic examination revealed that 3.5% of clinical partial responses and 3.4% of clinical stable disease were really pathological progressive disease. Clinical partial response and clinical stable disease positive predictive values were 92.8% and 90.9%, respectively, whereas the clinical progressive disease negative predictive value was 20%. Then, 6.9% of patients believed to have responded to the therapy, or not to have responded or worsened, actually had worsened by the end of the chemoradiotherapy. Conclusions Positive and negative predictive values, in particular for partial response and stable disease, of clinical evaluation of the response to chemoradiotherapy were not high enough to consider clinical evaluation accurate enough to make treatment decisions.
