Purpose The US Gastrointestinal Intergroup Radiation Therapy Oncology Group 98-11 anal carcinoma trial showed that cisplatin-based concurrent chemoradiotherapy resulted in a significantly higher rate of colostomy compared with mitomycin-based therapy. Established prognostic variables for patients with anal carcinoma include tumor diameter, clinical nodal status, and sex, but pretreatment variables that would predict the likelihood of colostomy are unknown. Methods A secondary analysis was performed by combining patients in the two treatment arms to evaluate whether new predictive and prognostic variables would emerge. Univariate and multivariate analyses were carried out to correlate overall survival (OS), disease-free survival, and time to colostomy (TTC) with pretreatment and treatment variables. Results Of 682 patients enrolled, 644 patients were assessable and analyzed. In the multivariate analysis, tumor-related prognosticators for poorer OS included node-positive cancer (P ≤ .0001), large (> 5 cm) tumor diameter (P = .01), and male sex (P = .016). In the treatment-related categories, cisplatin-based therapy was statistically significantly associated with a higher rate of colostomy (P = .03) than was mitomycin-based therapy. In the pretreatment variables category, only large tumor diameter independently predicted for TTC (P = .008). Similarly, the cumulative 5-year colostomy rate was statistically significantly higher for large tumor diameter than for small tumor diameter (Gray's test; P = .0074). Clinical nodal status and sex were not predictive of TTC. Conclusion The combined analysis of the two arms of RTOG 98-11, representing the largest prospective database, reveals that tumor diameter (irrespective of the nodal status) is the only independent pretreatment variable that predicts TTC and 5-year colostomy rate in patients with anal carcinoma.

ObjectiveThis study aimed to describe the pattern of recurrence and survival related to prognostic variables, including type of surgery as a clinical variable, in patients surgically treated for early cervix cancer.MethodsRecords of 2124 patients who underwent a radical hysterectomy for International Federation of Gynaecology and Obstetrics stage I/IIA cervical cancer between 1982 and 2011 were reviewed. Clinical-pathologic prognostic variables, also including extent of parametrectomy, were identified and used in a multivariable Cox proportional hazard model to explore associations between disease-free survival (DFS) and prognostic variables.ResultsThe 5-year DFS for the total group was 86%. Large tumor diameter, nonsquamous histology, lymph node metastases, parametrial involvement, lymph vascular space invasion, deep stromal invasion, and less radical surgery were independent poor prognostic variables for survival. Disease-free survival was independently associated with the type of radical hysterectomy with pelvic lymphadenectomy in favor of more radical parametrectomy (hazard ratio, 2.0; 95% confidence interval, 1.6–2.5). This difference was not found in tumors with a diameter of at least 20 mm.ConclusionsThis study confirms that variables such as large tumor diameter, nonsquamous histology, lymph vascular space invasion, deep stromal invasion, positive lymph nodes, and parametrial infiltration are poor prognostic variables in early cervix cancer treated by surgery. The extent of parametrectomy had no influence on survival in tumors of 20 mm or less. For larger tumors, a more radical hysterectomy might be associated with better DFS. Taking into account the possible bias in this study as a result of its retrospective design, ideally a prospective cohort study with clear definition of radicality is necessary to answer this important clinical question.

Purpose On initial publication of GI Intergroup Radiation Therapy Oncology Group (RTOG) 98-11 [A Phase III Randomized Study of 5-Fluorouracil (5-FU), Mitomycin, and Radiotherapy Versus 5-Fluorouracil, Cisplatin and Radiotherapy in Carcinoma of the Anal Canal], concurrent chemoradiation (CCR) with fluorouracil (FU) plus mitomycin (MMC) decreased colostomy failure (CF) when compared with induction plus concurrent FU plus cisplatin (CDDP), but did not significantly impact disease-free survival (DFS) or overall survival (OS) for anal canal carcinoma. The intent of the updated analysis was to determine the long-term impact of treatment on survival (DFS, OS, colostomy-free survival [CFS]), CF, and relapse (locoregional failure [LRF], distant metastasis) in this patient group. Patients and Methods Stratification factors included sex, clinical node status, and primary size. DFS and OS were estimated univariately by the Kaplan-Meier method, and treatment arms were compared by log-rank test. Time to relapse and CF were estimated by the cumulative incidence method and treatment arms were compared by using Gray's test. Multivariate analyses used Cox proportional hazard models to test for treatment differences after adjusting for stratification factors. Results Of 682 patients accrued, 649 were analyzable for outcomes. DFS and OS were statistically better for RT + FU/MMC versus RT + FU/CDDP (5-year DFS, 67.8% v 57.8%; P = .006; 5-year OS, 78.3% v 70.7%; P = .026). There was a trend toward statistical significance for CFS (P = .05), LRF (P = .087), and CF (P = .074). Multivariate analysis was statistically significant for treatment and clinical node status for both DFS and OS, for tumor diameter for DFS, and for sex for OS. Conclusion CCR with FU/MMC has a statistically significant, clinically meaningful impact on DFS and OS versus induction plus concurrent FU/CDDP, and it has borderline significance for CFS, CF, and LRF. Therefore, RT + FU/MMC remains the preferred standard of care.

Abstract Background: TAP (tumor abnormal protein) has been used as an important indicator in the early diagnosis of cancers, and some literatures showed that TAP can act as a prognostic factor in different kinds of cancer. The objective of this study was to explore the potential relationship between TAP and the prognosis of HCC after radical hepatectomy, and attempted to construct a robustly predictive nomogram on the strength of TAP and other prognostic variables of HCC patients.Methods: This retrospective study included 168 HCC patients (tumor recurrence occurred in 78 patients) who had undergone curative resection during January 2018 to June 2020 at the Department of Hepatopancreatobiliary Surgery of Liaoning Cancer Hospital & Institute. Serum TAP was detected by Abnormal Sugar Chain Structure of Glycoproteins, and according to the area of condensation particle, the whole population was categorized into the TAP high group (TAP≥225μm2) and TAP low group (TAP<225μm2).Results: There was no correlation between maximum tumor size and TAP. In the whole population or subgroups stratified by maximum tumor size, the recurrence-free survival (RFS) rate of the TAP low group was distinctly higher than TAP high group (P<0.05 for all). The multivariate analysis revealed that TAP (hazard ratio [HR], 3.47; 95% CI, 2.18-5.51; P<0.001), large tumor size (HR, 2.18; 95% CI, 1.36-3.49; P<0.001), poor tumor differentiation (HR, 0.53; 95% CI, 0.33-0.84; P=0.007) and presence of microvascular invasion (MVI) (HR, 2.03; 95% CI, 1.28-3.22; P=0.003) were independently associated with RFS. The prognostic implication of nomogram incorporating TAP, maximun tumor diameter, tumor differentiation and MVI was stronger than the model that integrated maximun tumor diameter, degree of tumor differentiation and MVI only.Conclusion: The present study suggested that higher preoperative TAP was correlated with undesirable prognosis in HCC patients who had undergone radical hepatectomy,and on the strength of prognostic variables identified by multivariate analysis, we constructed a robust nomogram for RFS of postoperative HCC patients.

4009 Background: An ∼65% 5-year disease-free-survival (DFS) rate from 5-FU/mitomycin/radiation for anal carcinoma needs improvement. Methods: A phase III randomized trial compared 5-FU (1,000mg/m2 days 1–4 and 29–32) plus mitomycin (10mg/m2 days 1 and 29) and radiation (45 to 59 Gy) (Arm A) to 5-FU (1,000mg/m2 days 1–4, 29–32, 57–60 and 85–88) plus cisplatin (75mg/m2 on days 1, 29, 57 and 85) and radiation (45 to 59 Gy; start day=57) (Arm B) in anal carcinoma patients. Stratification included gender, clinical N status and tumor diameter. Primary endpoint was DFS. Statistical power was 80% with two-sided test to detect 10% DFS increase for Arm B. Results: Of 682 patients accrued, 598 were analyzable. Most unanalyzed patients’ data are early. Patient characteristics were balanced. Median age was 55 years, women predominated (69%), 27.5% had >5 cm tumor diameter and 26% had clinically N+ cancer. Preliminary 5-year estimated DFS was 56% for Arm A and 48% for Arm B (p=0.28) and 5-year estimated overall survival was 69% for both arms (p=0.24). Men(p=0.04), clinically N+ cancer (p<0.0001) and tumor diameter >5 cm (p=0.005) independently prognosticated DFS in a multivariate analysis. 5-year colostomy rate was 10% for Arm A and 20% for arm B(p=0.12). Grade 3/4 toxicity rates: non-hematologic=76% for Arm A and 75% for Arm B but hematologic=67% for Arm A and 47% for Arm B(p=0.0004). Conclusions: In Intergroup-98–11, induction 5-FU/cisplatin followed by 5-FU/cisplatin/radiation failed to improve DFS compared to the standard treatment, 5-FU/mitomycin/radiation.

Purpose To analyze the Radiation Therapy Oncology Group (RTOG) database of patients with glioblastoma and appraise whether outcome was influenced by time to initiation of radiation therapy (RT). Patients and Methods From 1974 through 2003, adult patients with histologically confirmed supratentorial glioblastoma were enrolled onto 16 RTOG studies. Of 3,052 enrolled patients, 197 patients (6%) were either initially rendered ineligible or had insufficient chronologic data, leaving a cohort of 2,855 patients for the present analysis. We selected four patient groups based on the interval from surgery to the start of RT: ≤ 2 weeks, 2 to 3 weeks, 3 to 4 weeks, more than 4 weeks to the protocol eligibility limit of 6 weeks. Survival times were estimated by the Kaplan-Meier method. Multivariate analysis incorporated variables of time interval, recursive partitioning analysis (RPA) class, and treatment regimen. Results No decrement in survival could be identified with increasing time to initiation of RT. Among our four temporal groupings, median survival time was unexpectedly and significantly greater in the group with the longest interval (> 4 weeks) than in those with the shortest delay (≤ 2 weeks): respectively, 12.5 months versus 9.2 months (P < .0001). On multivariate analysis, with overall survival as the end point, time interval more than 4 weeks and lower RPA class were both significant predictors of improved outcome. Treatment regimen was not a significant factor. Conclusion There is no evident reduction in survival by delaying initiation of RT within the relatively narrow constraint of 6 weeks. An unanticipated yet significantly superior outcome was identified for patients for whom RT was delayed beyond 4 weeks from surgery.

Abstract Backgroud: Squamous cell carcinoma (SCCA) is the most common vulva cancer. This study purpose to evaluate the clinicopathological prognostic factors for survival outcomes of this disease after treated with surgery. Methods: All SCCA vulva cancer patients who underwent surgery between January 2006 and December 2017 were reviewed. The clinicopathological factors were analyzed to identify the prognostic factors for the progression-free survival (PFS) and overall survival (OS) using the Kaplan- Meier method and Cox-Proportional Hazard model.Results: One hundred twenty-five patients were recruited with a median age of 57 years. The recurrence rate was 35.2%. Patients with recurrence revealed a significant poorer five-year OS rate than those who did not recur (23.7% vs. 79.4%, P < 0.001). About 58.1% of palpable groin nodes revealed metastasis. The independent poor prognostic factors for PFS were groin node-positive and a tumor diameter more than 25 mm. whereas postmenopausal status, preoperative tumor area more than 11 cm2, and groin node enlargement were independent poor prognostic factors for OS. Conclusion: Groin node-positive and tumor diameter longer than 25 mm. were independent poor prognostic factors for PFS whereas postmenopausal status, large tumor area than 11 cm2, and enlargement of groin nodes were independent poor prognostic factors for OS. Patients with these factors should be closely followed.

Abstract Background: This work was designed to establish and verify our nomograms integrating clinicopathological characteristics with hematological biomarkers to predict both disease-free survival (DFS) and overall survival (OS) in solitary hepatocellular carcinoma (HCC) patients following hepatectomy.Methods: We scrutinized the data retrospectively from 414 patients with a clinicopathological diagnosis of solitary HCC from Guangxi Medical University Cancer Hospital (Nanning, China) between January 2004 and December 2012. Following the random separation of the samples in a 7:3 ratio into the training set and validation set, the former set was assessed by Cox regression analysis to develop two nomograms to predict the 1-year and 3-year DFS and OS (3-years and 5-years). This was followed by discrimination and calibration estimation employing Harrell’s C-index (C-index) and calibration curves, while the internal validation was also assessed.Results: In the training cohort, the tumor diameter, tumor capsule, macrovascular invasion, and alpha-fetoprotein (AFP) were included in the DFS nomogram. Age, tumor diameter, tumor capsule, macrovascular invasion, microvascular invasion, and aspartate aminotransferase (AST) were included in the OS nomogram. The C-index was 0.691 (95% CI: 0.644-0.738) for the DFS-nomogram and 0.713 (95% CI: 0.670-0.756) for the OS-nomogram. The survival probability calibration curves displayed a fine agreement between the predicted and observed ranges in both data sets. Conclusion: Our nomograms combined clinicopathological features with hematological biomarkers to emerge effective in predicting the DFS and OS in solitary HCC patients following curative liver resection. Therefore, the potential utility of our nomograms for guiding individualized treatment clinically and monitor the recurrence monitoring in these patients.

Cluster of differentiation (CD) 73, which is encoded by the NT5E gene, regulates production of immunosuppressive adenosine and is an emerging checkpoint in cancer immunotherapy. Despite the significance of CD73 in immuno-oncology, the roles of the NT5E gene methylation in breast cancer have not been well-defined yet. Therefore, we aimed to investigate the prognostic significance of the NT5E gene methylation in breast cancer. The DNA methylation status of the NT5E gene was analyzed using pyrosequencing in breast cancer tissues. In addition, the levels of inflammatory markers and lymphocyte infiltration were evaluated. The mean methylation level of the NT5E gene was significantly higher in breast cancer than in normal breast tissues. In the analysis of relevance with clinicopathologic characteristics, the mean methylation levels of the NT5E gene were significantly higher in patients with large tumor size, high histologic grade, negative estrogen receptor expression, negative Bcl-2 expression, and premenopausal women. There was no difference in disease-free survival according to the methylation status of the NT5E gene. We found that the NT5E gene methylation was related to breast cancer development and associated with poor prognostic factors in breast cancer. Our results suggest that the NT5E gene methylation has potential as an epigenetic biomarker in breast cancer.
