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.

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.

Refractory Itp

Abstract Corticosteroids have been the first line of treatment of ITP since 1950, however some patients do not respond to this treatment (refractory) and some will relapse after its discontinuation. For such patients second line treatments were introduced. Some patients will continue to be refractory to this treatment and need other therapy modality. Rituximab is a chimeric monoclonal antibody directed against the CD20 antigen exposing B Lymphocytes, causing its depletion. This could alter the production of auto-antibodies in some Auto-Immune diseases and thus could be used in their treatment. Few medical centers had reported using Rituximab in the treatment of refractory (ITP) and (AIHA), yet its definite role could not be determined, and here we share our experience. Patients with documented diagnosis of ITP or AIHA who were refractory to at least two lines of therapy including steroids were offered to receive Rituximab (375mg/m2 weekly for 4 weeks). 15 patients were enrolled, 10 with ITP, 4 with AIHA, 1 with Coombs negative Hemolytic anemia, and 1 with pure red cell aplasia. One had both ITP and AIHA. 10 were females and 5 males. 5 were >60 years old and 10 were < 60 years old. 2 out of the 10 patients with ITP had also Chronic Lymphocytic Leukemia (CLL). Duration of follow up ranged from 2 months to 17 months (average 7 mos). Of the 10 patients with refractory ITP treated with Rituximab overall response was 60%. 4 were NR (no response), 2 were MR (minimal response: Platelets increased to <50000), 2 were PR (Partial response: Platelets increased to <100000) and 2 were complete response (Platelets became normal). 3 patients of 6 with Hemolytic anemia or PRC aplasia had NR, 1 had MR (Hct <30), and 2 had partial response (Hct 30–35). No complete response was observed in this group. In 3 patients with hemolytic anemia and CLL 1 had MR, 1 had PR and 1 had NR. 2 patients with hemolytic anemia who had NR died as a complication of their disease (one with septic shock and one with severe autoimmune flare up). Only one patient with refractory ITP had mild allergic side effects and did not complete 4 doses. No Rituximab related mortality was observed. CONCLUSION: Rituximab therapy had a variable but valuable effect in the treatment of patients with chronic refractory ITP and refractory/ relapsed AIHA. Overall response in our group reached 60%. No clinical or laboratory parameters were found to predict response, although there was a suggestion that males, younger age, and no history of splenectomy have a better chance of response. As we lack an effective alternative treatment in chronic refractory ITP and AIHA, Rituximab use could be a valid option in view of its mild toxicity. Further follow up of our patients and input from other institutions in this regard are needed.

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.

Εισαγωγή: O καρκίνος του πνεύμονα αποτελεί το 28% όλων των θανάτων που σχετίζονται με καρκίνο και περίπου στο 80% των περιπτώσεων αφορά στο Μη Μικροκυτταρικό καρκίνωμα. H σισπλατίνη είναι από τα δραστικότερα και πιο αποτελεσματικά κυτταροτοξικά φάρμακα στη θεραπεία των επιθηλιακών κακοηθειών, που όμως οι σοβαρές ανεπιθύμητες ενέργειες και η αντίσταση στην χορήγηση της, εγείρουν την ανάγκη βελτιωμένων μορφών αυτού του φαρμάκου. Mία λιποσωμιακή μορφή της σισπλατίνης, είναι η Λιποπλατίνη (Lipoplatin™), η οποία αναπτύχθηκε με σκοπό να μειώσει τη συστηματική τοξικότητα της σισπλατίνης και να αυξήσει τη δραστικότητά της έναντι των όγκων. Σκοπός: Η ανάλυση και εκτίμηση των απεικονιστικών ευρημάτων, στα οποία κατά κύριο λόγο βασίζεται η αξιολόγηση της ανταπόκρισης στη χημειοθεραπεία (σύμφωνα με τα κριτήρια RECIST 1.1) η συσχέτιση τους με τον ιστολογικό τύπο του καρκίνου σε ασθενείς που λαμβάνουν μέρος σε τυχαιοποιημένη, συγκριτική, ανοιχτής αγωγής, προοδευτική μελέτη φάσης II και η εκτίμηση του ποσοστού αντικειμενικής ανταπόκρισης (Overall Response Rate-ORR) στους ασθενείς των δύο ομάδων. Οι συνδυασμοί χημειοθεραπείας είναι για την πρώτη ομάδα της μελέτης, Λιποπλατίνη και γεμσιταβίνη, ενώ για την δεύτερη ομάδα σισπλατίνη και γεμσιταβίνη, ως θεραπείες πρώτης γραμμής σε Μη Μικροκυτταρικού τύπου, καρκίνο του πνεύμονα (Στάδιο IIIβ/ IV).Δευτερεύοντες στόχοι είναι να συγκριθούν στις δύο ομάδες : το ποσοστό ελέγχου της ασθένειας (DCR), η επιβίωση χωρίς εξέλιξη της νόσου (PFS), η διάρκεια της ανταπόκρισης, η συνολική επιβίωση, η ασφάλεια και η ανεκτικότητα του συνδυασμού θεραπείας.Ασθενείς και Μέθοδος: Η Μελέτη πραγματοποιήθηκε στο νοσοκομείο Μεταξά (2η παθολογική κλινική, υπεύθυνος ερευνητής: Μυλωνάκης Νικόλαος). Τα βασικά κριτήρια συμπερίληψης ασθενών στη μελέτη είναι η ιστολογικά ή κυτταρολογικά επιβεβαιωμένη διάγνωση Μη μικροκυτταρικού καρκίνου του πνεύμονα (NSCLC) σε ασθενείς άνω των 18 ετών με τοπικά προχωρημένο ή μεταστατικό NSCLC.Τα κυριότερα κριτήρια αποκλεισμού είναι η προηγηθείσα χορήγηση άλλου είδους χημειοθεραπεία, βεβαρημένο ιατρικό ιστορικό και η είσοδος στη μελέτη σε χρονικό διάστημα λιγότερο των 3 εβδομάδων από μεγάλη χειρουργική επέμβαση.Οι ασθενείς τυχαιοποιούνται κεντρικά κατά την εισαγωγή τους στην ομάδα Α (Λιποπλατίνη και γεμσιταβίνη) ή στην ομάδα Β (σισπλατίνη και γεμσιταβίνη). Τo θεραπευτικό σχήμα της ομάδας A αποτελείται από: Λιποπλατίνη 120 mg/m2 (ημέρες 1, 8, 15 σε έναν κύκλο 21 ημερών, για 3 διαδοχικούς κύκλους) και γεμσιταβίνη 1000 mg/m2 (ημέρες 1, 8 σε έναν κύκλο 21 ημερών, για 3 διαδοχικούς κύκλους). Στην ομάδα Α δεν θα γίνεται προ- ή μετά- ενυδάτωση και δεν θα χρησιμοποιείται φυσιολογικός ορός, ενώ ο ρυθμός έγχυσης θα πρέπει να είναι αργός ιδίως στην αρχή αυτής. Το σχήμα της ομάδας B (χημειοθεραπευτική αγωγή αναφοράς) αποτελείται από σισπλατίνη 100 mg/m2 (ημέρα 1, σε έναν κύκλο 21 ημερών, για 3 διαδοχικούς κύκλους) και γεμσιταβίνη 1000 mg/m2 (Hμέρες 1, 8 σε έναν κύκλο 21 ημερών, για 3 διαδοχικούς κύκλους). Η σισπλατίνη θα χορηγείται ως δίωρη ενδοφλέβια έγχυση με ένα λίτρο φυσιολογικού ορού προενυδάτωση και βεβιασμένη διούρηση. Σε αμφότερες τις ομάδες θα συνεχιστεί η ίδια θεραπευτική αγωγή για 3 κύκλους επιπλέον, κατόπιν ανταπόκρισης ή σταθεροποίησης της νόσου. Η αξιολόγηση των ασθενών θα γίνεται σε 4 χρονικές περιόδους: πριν από την έναρξη της θεραπείας, εβδομαδιαία αξιολόγηση (την έβδομη ημέρα μετά από κάθε έγχυση), μετά από 3 και 6 κύκλους θεραπείας και κάθε 3 μήνες δια βίου. Ο έλεγχος των ασθενών θα περιλαμβάνει ιατρικό ιστορικό, φυσική εξέταση, γενική αίματος και πλήρη βιοχημικό έλεγχο με καταγραφή των ανεπιθύμητων ενεργειών. Η αξιολόγηση των ασθενών απεικονιστικά πριν την έναρξη και μετά από 3 και 6 κύκλους θεραπείας. Οι απεικονιστικές μέθοδοι περιλαμβάνουν ακτινογραφία και αξονική τομογραφία θώρακος, αξονικές τομογραφίες κοιλίας, εγκεφάλου και σπινθηρογράφημα οστών αν είναι απαραίτητο. Όλες οι απεικονιστικές εξετάσεις θα διενεργούνται σύμφωνα με τα συνήθη διεθνή πρωτόκολλα, όχι απαραίτητα σε προεπιλεγμένα κέντρα αφού η εισαγωγή και παρακολούθηση των ασθενών στη μελέτη θα πραγματοποιείται κατόπιν διάγνωσης NSCLC σε οποιοδήποτε κέντρο.Αποτελέσματα: Τα απεικονιστικά ευρήματα ανά ιστολογικό τύπο, των ασθενών που έλαβαν μέρος στη μελέτη δεν ήταν διαφορετικά από αυτά που αναφέρονται στην βιβλιογραφία. Η εντόπιση του αδενοκαρκινώματος είναι στις περισσότερες περιπτώσεις περιφερική. Το καρκίνωμα εκ πλακωδών κυττάρων έχει κεντρική εντόπιση στο μεγαλύτερο ποσοστό των ασθενών. Στο σύνολο των ασθενών η εντόπιση υπερέχει στον δεξιό πνεύμονα και στον άνω λοβό. Η κοιλοποίηση, οι αποτιτανώσεις και η προσβολή των πλευρών είναι πιο συχνή στο εκ πλακωδών κυττάρων καρκίνωμα. Η ανάλυση της αποτελεσματικότητας της μελέτης πραγματοποιήθηκε με βάση τα απεικονιστικά ευρήματα χρησιμοποιώντας τα κριτήρια RECIST 1.1. Μερική ανταπόκριση (Partial Response-PR) μετά από την ολοκλήρωση 3 κύκλων παρουσίασε το 31,7% των ασθενών στο Α σκέλος και το 25,6% στο Β αντίστοιχα. Σταθερή νόσος (Stable Disease-SD) παρατηρήθηκε στο 39% των ασθενών στο Α σκέλος, ενώ στο Β ήταν 30,8%. Σε κανένα σκέλος δεν υπήρξε πλήρης ανταπόκριση (Complete Response-CR). Αν και η διαφορά στην ανταπόκριση μεταξύ των δύο ομάδων δεν είναι στατιστικά σημαντική ωστόσο τα αποτελέσματα είναι ενθαρρυντικά αφού η Λιποπλατίνη όχι μόνο δεν υπήρξε υποδεέστερη της σισπλατίνης αλλά επιπλέον είχε μικρότερη τοξικότητα συγκριτικά με την σισπλατίνη. Μια διαφορά που ήταν στατιστικά σημαντική μεταξύ των δύο ομάδων ήταν στη νεφροτοξικότητα. Επιπροσθέτως στην περίπτωση του αδενοκαρκινώματος φαίνεται ότι η Λιποπλατίνη έχει πολύ καλύτερη ανταπόκριση συγκριτικά με την σισπλατίνη (16,7% πρόοδο νόσου έναντι 45,8%) ενώ στην περίπτωση του καρκινώματος εκ πλακωδών κυττάρων τα αντίστοιχα ποσοστά ήταν 46,1% και 37,5%. Συμπέρασμα: Η λιποσωμιακή μορφή της σισπλατίνης παρουσιάζει λιγότερες παρενέργειες συγκριτικά με την σισπλατίνη όταν συνδυάζεται με την γεμσιταβίνη και ειδικότερα στατιστικά σημαντική μικρότερη νεφροτοξικότητα. Ιδιαίτερα σημαντικό επίσης είναι το γεγονός ότι στους ασθενείς της ομάδας που έλαβαν Λιποπλατίνη δεν έγινε προ ενυδάτωση ούτε βεβιασμένη διούρηση. Επιπροσθέτως η Λιποπλατίνη παρουσιάζει μία μεγαλύτερη αποτελεσματικότητα η οποία δεν είναι στατιστικά σημαντική λόγω του μικρού δείγματος ασθενών ωστόσο στην περίπτωση του αδενοκαρκινώματος παρουσιάζει μία στατιστικά σημαντική διαφορά στην ανταπόκριση έναντι της σισπλατίνης.

Abstract Introduction : Daratumumab (DARA) is a novel human CD-38-targeting monoclonal antibody in clinical development for multiple myeloma (MM). In two clinical studies (NCT00574288 [GEN501] and NCT01985126 [Sirius]), DARA monotherapy showed remarkable clinical activity and was well tolerated in heavily treated patients (pts) with relapsed and refractory (RR) MM (Lokhorst HM. J Clin Oncol 2014;32 Suppl:abstr 8513. Lonial S. J Clin Oncol 2015;33 Suppl: abstr LBA8512). A combined analysis of efficacy of 16 mg/kg DARA in these two studies is presented. Methods : GEN501, a first-in-human open-label, two-part (Part 1 dose escalation; Part 2 dose expansion) study, enrolled pts with MM that had relapsed after or were refractory to ≥2 prior therapies. Sirius, an open-label, two-part study, enrolled pts with MM with ≥3 prior therapies, including a PI or IMiD, or were refractory to both a PI and an IMiD. Eligibility criteria included pts with absolute neutrophil count ≥1000/mm3, hemoglobin ≥7.5 g/dL, platelet count ≥75×109/L (GEN501) or ≥50×109/L (Sirius), and alanine aminotransferase ≤3.5 (GEN501) or ≤2.5 (Sirius) times the upper limit of normal. In GEN501 Part 2, the first 16 mg/kg DARA infusion was followed by a 3 week rest period, and then qw for 7 weeks, q2w for 14 weeks, and q4w thereafter. In Sirius, 16 mg/kg DARA was infused qw for 8 weeks, q2w for 16 weeks, and q4w thereafter. The combined analysis comprised pts treated with 16 mg/kg DARA in Sirius and Part 2 of GEN501. In both studies overall response rates (ORR) were assessed according to IMWG response criteria. Results: The combined analysis included 148 pts (42 and 106 pts from GEN501 and Sirius, respectively). The median (range) age was 64 (31-84) years. Median time since initial diagnosis was 5.8 and 4.8 years in GEN501 and Sirius, respectively, and 62% and 82% of pts had received >3 prior therapies, respectively. In GEN501, 76% of pts were refractory to their last therapy and 64% were refractory to both a PI and IMiD; a greater proportion of pts in Sirius were refractory to their last therapy (97%) and double refractory to a PI and IMiD (95%). The ORR was 36% in GEN501 and 29% in Sirius; the ORR for the combined analysis was 31%. Best overall response is shown in Table. Responses deepened over time and the combined rate of very good partial response (VGPR) or better was 11% with 2 pts with complete responses (CR) and 3 with stringent CRs (sCR) across the two studies. In the combined analysis, median duration of response was 7.6 months and 46% of responders remained progression free at 1-year after a median follow-up of 9.3 months. Median overall survival (OS) had not been reached at median follow-up times of 10.2 months (GEN501) and 9.3 months (Sirius). The estimated 1-year OS rate (95% CI) was 77% (58-88), 65% (51-76), and 69% (58-77) for GEN501, Sirius, and the combined analysis, respectively. Forty-four of 46 responders were still alive at the time of the primary analysis. At a subsequent data cutoff for the combined analysis, after a median follow-up of 14.8 months, the estimated median OS was 19.9 months (95% CI, 15.1 - not estimable). ORR was similar across prespecified subgroups which included age, ISS stage, number of prior therapies, and refractory status. Conclusions : Single-agent DARA (16 mg/kg) demonstrated remarkable clinical activity (31% ORR) in a combined analysis of two studies in heavily pretreated MM pts. The quality of the observed responses (11% VGPR or better, 2 CRs, and 3 sCRs) was noteworthy in this highly refractory population. DARA shows promising activity in pts who have exhausted other approved myeloma treatment options. Table.

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.

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.

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.

Latar belakang: Kemoradiasi meningkatkan survival rate pada karsinoma nasofaring (KNF) stadium lanjut. Waktu tunggu radioterapi lebih dari 2 bulan dan keterbatasan alat radiasi mengakibatkan neoadjuvant chemotherapy (NAC) platinum-based menjadi pilihan. Tujuan: Untuk mengetahui respon NAC platinum-based pada KNF. Metode: Penelitian cohort retrospective menggunakan rekam medis di RSUP Dr Kariadi Semarang 2007-2012. Sampel dibagi 2 kelompok: NAC 3 siklus dan lebih dari 3 siklus. Hubungan jumlah siklus dengan respon terapi pada tumor primer nasofaring dan kelenjar limfe leher diuji dengan chi square. Penilaian respon terdiri dari respon positif (complete response (CR), partial response (PR)), respon negatif (stable disease (SD) dan progressive disease (PD)).Hasil: Dari 97 sampel, 46 mendapat 3 siklus dan 51 lebih dari 3 siklus. Respon positif kelenjar limfe leher pada kelompok 3 siklus sebesar 67,4% (CR 30,5% dan PR 36,9%) dan tumor primer sebesar 50% (CR 11,9% dan PR 38,1%), sedangkan respon positif kelenjar limfe leher pada kelompok lebih dari3 siklus sebesar 78,4% (CR 56,8% dan PR 21,6%) dan tumor primer sebesar 62,5% (CR 23,9% dan PR 38,6%). Terdapat hubungan yang bermakna antara jumlah siklus dengan respon tumor primer (p=0,021). Penderita yang tidak mengalami penundaan terapi berpengaruh 4,6 kali lebih besar menyebabkan respon positif dibandingkan dengan yang mengalami penundaan. Jumlah siklus lebih dari 3 berpengaruh 2,8 kali lebih besar menyebabkan respon positif dibandingkan 3 siklus. Kesimpulan: Pemberian NAC platinum-based lebih dari 3 siklus mempunyai respon lebih baik daripada 3 siklus. Faktor penundaan berpengaruh lebih besar terhadap respon dibandingkan jumlah siklus. Kata kunci: Neoadjuvant chemotherapy platinum-based, respon terapi, karsinoma nasofaring.
