AbstractDeletion 13q is recommended in the initial cytogenetic workup of myeloma patients. The patterns of this abnormality have been shown to have differential prognostic value. The presence of monosomy 13 is associated with a significantly poor progression-free survival, while interstitial deletion 13q is associated with significant improvement in the overall survival. We analyzed the patterns of 13q abnormalities on fluorescent in situ hybridization (FISH) assay results in myeloma patients. Deletion 13q abnormalities were observed in 38% (55 of 138) of the myeloma patients. Ten (18%) and 44 (80%) patients showed interstitial deletion and terminal deletion, respectively. One had a mosaic of both the patterns. Nine of the ten patients with interstitial deletions were males. For terminal deletion 13q, there appeared to be a slight female predilection, with a male to female ratio of 0.83:1. Half of the patients with deletion 13q had coexistent cytogenetic abnormalities. We suggest a baseline FISH for deletion 13q and specification of the type of abnormality (terminal vs. interstitial) in patients with myeloma. Based on our observation in conjunction with the available literature, further studies in a large cohort of patients with survival data are warranted to clearly delineate the role of deletion 13q in myeloma.

AbstractBackgroundChromosomal instability is associated with earlier progression in isocitrate dehydrogenase (IDH)–mutated astrocytomas. Here we evaluated the prognostic significance of polysomy in gliomas tested for 1p/19q status.MethodsWe analyzed 412 histologic oligodendroglial tumors with use of 1p/19q testing at 8 institutions from 1996 to 2013; fluorescence in situ hybridization (FISH) for 1p/19q was performed. Polysomy was defined as more than two 1q and 19p signals in cells. Tumors were divided into groups on the basis of their 1p/19q status and polysomy and were compared for progression-free survival (PFS) and overall survival (OS).ResultsIn our cohort, 333 tumors (81%) had 1p/19q loss; of these, 195 (59%) had concurrent polysomy and 138 (41%) lacked polysomy, 79 (19%) had 1p/19q maintenance; of these, 30 (38%) had concurrent polysomy and 49 (62%) lacked polysomy. In agreement with prior studies, the group with 1p/19q loss had significantly better PFS and OS than did the group with 1p/19q maintenance (P < 0.0001 each). Patients with 1p/19q loss and polysomy showed significantly shorter PFS survival than patients with 1p/19q codeletion only (P < 0.0001), but longer PFS and OS than patients with 1p/19q maintenance (P < 0.01 and P < 0.0001). There was no difference in survival between tumors with >30% polysomic cells and those with <30% polysomic cells. Polysomy had no prognostic significance on PFS or OS in patients with 1p/19q maintenance.ConclusionsThe presence of polysomy in oligodendroglial tumors with codeletion of 1p/19q predicts early recurrence and short survival in patients with 1p/19q codeleted tumors.

SummaryKallikrein-related peptidases, a subgroup of the serine protease enzyme family, are considered to be important prognostic biomarkers in cancer. In this study we sought to determine the prognostic value of kallikrein-related peptidase 8 (KLK8,hK8,KLK-8) in ovarian cancer using a novel method of compartmentalised in situ protein analysis. A tissue array composed of 150 advanced stage ovarian cancers, uniformly treated with surgical debulking followed by platinum-paclitaxel combination chemotherapy, was constructed. For the evaluation of kallikrein-related peptidase 8 protein expression, we used an immunofluorescence-based method of automated in situ quantitative protein analysis (AQUA). Mean follow-up time of the cohort was 34.35 months. One hundred twenty-six of 150 cases had sufficient tissue for AQUA analysis. There were significant correlations between tumour mask KLK8 protein expression levels and clinicopathological variables, including grade (p=0.0011), residual disease (p=0.0063) and clinical response to chemotherapy(p=0.0346). In univariate survival analysis there was a significant correlation between KLK8 tumour mask expression and five years progression-free survival, meanwhile it was not associated with five-year overall survival (p =0.0694). Specifically, low KLK8 expression correlated with better outcome (top vs. bottom quartile, p=0.0319). In multivariate survival analysis, adjusting for well-characterised prognostic variables, tumour KLK8 expression level retained its prognostic significance for progression-free survival (95%CI: 0.341–1.027, p=0.045). The possibility that KLK8 may be a suitable candidate as a diagnostic and prognostic marker warrants further investigation.

266 Background: ENZ significantly increased OS for men with metastatic castration-resistant prostate cancer (mCRPC) vs. placebo and significantly decreased PSA levels. However, the prognostic significance and role of PSA falls as a surrogate for OS are not established. Methods: Men in the AFFIRM trial were grouped by maximal unconfirmed PSA decline during the 1st 90 days of treatment in a post-hoc analysis. Each PSA decline criterion was assessed for surrogacy for OS by the proportion of treatment effect (PTE)-explained and Prentice criteria. We also assessed the association of PSA decline with OS, progression-free survival (PFS), and pain response. Results: ENZ improved OS (hazard ratio 0.63, p < 0.001) and was associated with higher rates of PSA declines when compared to placebo (odds ratio > 19.0, p < 0.001). Greater declines in PSA were associated with longer OS, PSA PFS, radiographic PFS, and higher pain response when compared with no PSA decline or PSA increase (table). All decline measures from baseline were highly prognostic for OS and several ( > 0%, ≥ 30%, ≥ 50% declines) explained a proportion of the treatment effect (PTE 1.07–1.29, 95% CI lower bounds > 0.63), in which treatment was no longer significant after adjustment for the decline measures (p > 0.20). Full surrogacy was not demonstrated. Conclusions: In AFFIRM, > 0, ≥30%, and ≥50% PSA declines within 90 days of treatment fulfilled Prentice surrogacy criteria 1–3. Prentice 4, equivalency of survival adjusting for PSA decline outcomes, could not be demonstrated. PSA declines are associated with longer PFS and improved pain response. External prospective validation is needed. Clinical trial information: NCT00974311. [Table: see text]

Purpose. The prognostic value of a new scoring system, termed F-NLR, that combines pretreatment fibrinogen level with neutrophil-lymphocyte ratio has been evaluated in various cancers. However, the results are controversial. The purpose of this study was to comprehensively analyze the prognostic value of F-NLR score in patients with cancers. Methods. An integrated search of relevant studies was conducted by screening the PubMed and Embase databases. Pooled hazard ratios, with 95% confidence intervals (CIs), for overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS) were calculated to estimate the prognostic significance of F-NLR score in patients with various tumors. A random effects model was used for comprehensive analysis, and subgroup and meta-regression analyses were used to explore sources of heterogeneity. Results. Thirteen articles reporting data from of 4747 patients were included in the study. Pooled analysis revealed that high F-NLR score was significantly associated with poor OS ( HR = 1.77 ; 95% CI, 1.51–2.08) and poor DFS/PFS ( HR = 1.63 ; 95% CI, 1.30–2.05). Subgroup and meta-regression analyses did not alter the prognostic role of F-NLR score in OS and DFS/PFS. Conclusions. Increased F-NLR score is significantly associated with poor prognosis in patients with cancers and can serve as an effective prognostic indicator.

Abstract Introduction The role of chemotherapy alone in newly diagnosed WHO grade 2 oligodendroglioma after biopsy, incomplete or gross total resection remains controversial. We here analyze the clinical outcome of four patient cohorts being treated with either procarbazine, CCNU and vincristine (PCV) or temozolomide (TMZ) after biopsy, resection only, or wait-and-scan after biopsy. Methods Patients (n = 142) with molecularly defined oligodendroglioma (WHO 2016) were assigned to four cohorts: W&S, wait-and-scan after stereotactic biopsy (n = 59); RES, surgical resection only (n = 27); TMZ, temozolomide after biopsy (n = 26) or PCV (n = 30) after biopsy. Presurgical MRI T2 tumor volumes were obtained by manual segmentation. Progression-free survival (PFS), post-recurrence PFS (PR-PFS) and rate of histological progression to grade 3 were analyzed. Results PFS was longest after PCV (9.1 years), compared to 5.1 years after W&S, 4.4 years after RES and 3.6 years after TMZ. The rate of histological progression from grade 2 to 3 within 10 years was 9% for the PCV, 29% for the W&S, 67% for the RES and 75% for the TMZ group (p = 0.01). In the W&S group, patients treated with PCV at first relapse had a longer PFS from intervention than those treated with TMZ (7.2 vs 4.0 years, p = 0.04). Multivariate analysis identified smaller tumor volume prior to any intervention (p = 0.02) to be prognostic for PFS. Conclusions PCV chemotherapy alone is an effective treatment for WHO grade 2 oligodendroglioma, with long PFS and low rate of histological progression.

e15586 Background: In Saudi Arabia, the incidence of colorectal cancer has been increased over the past few years. The optimal treatment beyond the second line is not fully understood. To the best of our knowledge, the efficacy and disease outcomes of triflurodine/tipiracil in Saudi patients with refractory metastatic colorectal cancer(mCRC) has not been studied yet. Our study is a real-life practice evaluation of the efficacy of triflurodine/tipiracil in patients with refractory mCRC. Moreover, the prognosis and the prognostic significance of the different clinical variables have been analyzed. Methods: A retrospective, multi-centers ( 5 centers representative of Saudi Arabia )observational study in patients with mCRC who have received triflurodine/tipiracil beyond oxaliplatin & Irinotecan-based chemotherapy between December 2018-December 2020.We aimed to assess the response to triflurodine/tipiracil, to evaluate the progression-free survival (PFS ), the overall survival (OS), and the associated factors of prognostic significance. Results:The data of 100 patients with refractory mCRC who has received triflurodine/tipiracil have been analyzed. The mean age was 55.2 +11.8 years. Forty-two patients were (42%) females and 58 (58%) were male patients. Sigmoid was the most common primary site of cancer in 35 (35%) patients, followed by rectum 29 (29%). Peritoneal metastasis was present in 17 (23.3%) patients ,liver in 51(56.6%) and lung in 39 (50.7%). Metastatic sites were ≥ 2 in 45 (45%) patients. Metastatic lesions were ≥ 5 in 65 (65%) patients. Xelox chemotherapy regimen was the most commonly used first-line chemotherapy which represents 43%, while Folfiri or Xeliri combination was the most used second line in 57 (60%). For the third line, Folfox or Xelox was used in 81 (83.5%) patients. The fourth line was given to 49 (67.1%). For first-line biological agents, Cetuximab was used most frequently 31 (46.3%).Evaluation of the response to treatment with triflurodine/tipiracil revealed one patient (1%) with a complete response,3 patients (3%) with partial response, 28 (28%) patients with stable disease, and 66 (66%) showed progressive disease. The estimated median progression-free survival was 5 months ( 3.839 - 6.161) and the median overall survival was 12 months (9.732-14.268). The log-rank analysis showed that the baseline neutrophils ≤ 75 % ( P-value= 0.0092) and low hemoglobin level (P-value= 0.0245) were strongly associated with a higher survival. By multivariate Cox regression analysis, the neutrophil count ≤ 75 % was the only independent predictor for survival. Conclusions: Trifluridine/tipiracil is effective in patients with refractory mCRC. The low neutrophil count might predict a better overall survival.

ObjectiveThis retrospective study examined the clinicopathologic features of adenosarcoma patients to determine potential prognostic factors and retrospectively evaluated overall survival (OS), disease-free survival (DFS), and local recurrence-free survival (LRFS) after primary treatment of adenosarcoma including surgery, radiation, and chemotherapy.MethodsOne hundred sixty-five patients with adenosarcoma were identified from the MD Anderson Cancer Center tumor registry between 1982 and 2014. Clinical data were collected retrospectively. Pathologic characteristics were examined by sarcoma pathologists. We used the Kaplan-Meier method to estimate OS, DFS, and LRFS. The log-rank test was performed to test the difference in survival between groups. Multivariate regression analyses of survival data were conducted using the Cox proportional hazards model.ResultsMedian OS and DFS for all patients were 8.5 and 4.7 years, respectively. Pathologic characteristics that influence OS and DFS were sarcomatous overgrowth (SO), myometrial invasion (MI), lymphovascular invasion (LVI), tumor size, number of mitosis, estrogen receptor, progesterone receptor, International Federation of Gynecology and Obstetrics (FIGO) stage, age, and resection status. Median OS for adenosarcoma patients with SO was 5.2 versus 14.5 years for patients without SO (P < 0.0001). Median OS for adenosarcoma patients with MI was 5.8 years versus not reached for patients without MI (P = 0.0005). Median OS for adenosarcoma patients with LVI was 1.0 versus 8.9 years for patients without LVI (P = 0.0021). On Cox analysis for OS and DFS and LRFS, only SO, MI, LVI, age, resection status, and FIGO stage remained significant. There was no difference in OS or LRFS for adjuvant radiation versus no adjuvant radiation (P = 0.17, P = 0.076).ConclusionsThis study highlights the importance of LVI as a prognostic factor and confirms the prognostic significance of SO, MI, age, resection status, and FIGO stage for adenosarcoma. Furthermore, this study suggests that there is no additional benefit to adjuvant radiation. The standard-of-care treatment for adenosarcoma should remain total abdominal hysterectomy bilateral salpingo-oophorectomy +/− lymphadenectomy and no adjuvant radiation.

AbstractTo define prognostic impact of Epstein-Barr virus (EBV) infection in diffuse large B-cell lymphoma (DLBCL), we investigated EBV status in patients with DLBCL. In all, 380 slides from paraffin-embedded tissue were available for analysis by EBV-encoded RNA-1 (EBER) in situ hybridization, and 34 cases (9.0%) were identified as EBER-positive. EBER positivity was significantly associated with age greater than 60 years (P = .005), more advanced stage (P < .001), more than one extranodal involvement (P = .009), higher International Prognostic Index (IPI) risk group (P = .015), presence of B symptom (P = .004), and poorer outcome to initial treatment (P = .006). The EBER+ patients with DLBCL demonstrated substantially poorer overall survival (EBER+ vs EBER− 35.8 months [95% confidence interval (CI), 0-114.1 months] vs not reached, P = .026) and progression-free survival (EBER+ vs EBER− 12.8 months [95% CI, 0-31.8 months] vs 35.8 months [95% CI, 0-114.1 months], respectively (P = .018). In nongerminal center B-cell–like subtype, EBER in situ hybridization positivity retained its statistical significance at the multivariate level (P = .045). Nongerminal center B-cell–like patients with DLBCL with EBER positivity showed substantially poorer overall survival with 2.9-fold (95% CI, 1.1-8.1) risk for death. Taken together, DLBCL patients with EBER in situ hybridization+ pursued more rapidly deteriorating clinical course with poorer treatment response, survival, and progression-free survival.
