14506 Background: Survival probability changes for patients who have already survived one or more years following diagnosis, and is more accurately represented by conditional survival. The specific aims of this study were to determine the 5-year conditional survival rates for prostate cancer patients. Methods: Using the Surveillance, Epidemiology, and End Results (SEER 11) database from the NCI, we analyzed 66,822 prostate cancer patients diagnosed between 1988 and 1994 that were staged using the SEER-modified AJCC staging system (3rd edition). Using the life table method, we computed observed 5-year conditional survival, stratified by stage, age, and race, for patients who had already survived 0 to 5 years after diagnosis. Results: For each category, we compared baseline 5-year observed survival at diagnosis with 5-year observed conditional survival after having already survived 5 years. Survival decreased from 79% to 67% for Stage I, decreased from 80% to 71% for Stage II, decreased from 83% to 75% for Stage III, but increased from 38% to 49% for Stage IV patients. Survival rates did not change for patients <70 years (79–80%), but decreased from 61% to 55% for patients >70 years old. Although blacks (60–62%) had lower survival than whites (69–71%), no race had any appreciable change in their conditional survival for those who had survived 5 years from diagnosis. Conclusions: For prostate cancer patients who have already survived some time after diagnosis, the expected 5-year conditional survival increases for Stage IV patients, but decreases for other stages and for older patients. Conditional survival can provide more accurate longer term prognostic information for prostate cancer patients who have already survived a number of years after diagnosis.

Objective: The last edition of the AJCC staging system eliminated the pT2 subclassification of prostate cancer (PCa). Our objective was to evaluate the association of pT2 subclassification with the oncological results of patients with PCa who underwent radical prostatectomy (RP). Material and methods: We evaluated 367 patients who underwent RP between 2009 and 2016, with pT2 disease in the final pathological evaluation. We assessed differences in rates of biochemical recurrence (BCR), metastasis and mortality between T2 substages (pT2a/b vs pT2c). Results: Fifty-three (14.4%) patients presented pT2a/b disease and 314 (85.6%) pT2c disease. The mean follow-up time was 4.9 ± 2.6 years. Grade group scores (p = 0.1) and prostate specific antigen (PSA) (p = 0.2) did not differed between pT2 substages. The rate of BCR in pT2a/b and pT2c patients was 11.3% and 18.2%, respectively (p = 0.2). Five (9.4%) patients with pT2a/b and 45 (14.3%) with pT2c substage underwent salvage radiotherapy (p = 0.3). The rate of positive surgical margins did not differ between groups (p = 0.2). Seven (2.2%) patients with pT2c had lymph nodes or distant metastases. The overall survival was 92.5% and 93.6% in pT2a/b and pT2c, respectively (p = 0.2). Conclusion: Our results are in accordance with the changes introduced in the 8th edition of the AJCC staging system in which the pT2 subclassification was eliminated.

Abstract Introduction Despite the acceptance of concomitant chemoradiation (CRT) as an alternative to total laryngectomy (TL) in locally advanced laryngeal cancer (LALC), laryngeal preservation is sparingly recommended in developing countries. We report on prognostic factors and survival in T3/T4 laryngeal cancer treated with concomitant CRT at Shaukat Khanum Memorial Cancer Hospital and Research Center (SKMCH and RC) to provide comparison with other geographic locations. Material and Methods During the period November 2003-April 2009, 101 patients with biopsy proven untreated LALC underwent concurrent CRT treatment at SKMCH and RC. According to AJCC staging system (6th edition) 41 had T3 and 60 patients had T4 disease. Radiation dose to the larynx was 70 Gy in 35 fractions with concomitant cisplatin. Induction chemotherapy was given to 42 patients. Thirty-one patients required tracheotomy either before or during concomitant CRT. Results Actuarial overall survival and laryngectomy free survival (LFS) for the whole group at 5 years were 54% (95% CI; 48-60) and 47% (95% CI; 42-52) respectively. Median LFS was 4.17 years. On univariate analysis patients with T4 tumors (p = 0.04), positive neck nodal disease (p = 0.02), supraglottic site (p = 0.02) and tracheotomy (0.009) had a significantly inferior LFS. Multivariate analysis showed tracheotomy to be the only factor significantly (p = 0.03) related to a higher risk of failure for LFS. Conclusion Survival rates for LALC treated with concomitant CRT in our institution are acceptable. Our study supports the use of TL in patients with compromised airways that require tracheotomy as outcome with concomitant CRT is poor.

Abstract Background: For selected locally advanced prostate cancer (PCa) patients, radical prostatectomy (RP) is one of the first-line treatments. We aimed to develop a preoperative nomogram to identify what kinds of patients can get the most survival benefits after RP. Methods: We conducted analyses with data from the Surveillance, Epidemiology, and End Results (SEER) database. Covariates used for analyses included age at diagnosis, marital status, race, American Joint Committee on Cancer (AJCC) 7th TNM stage, Prostate specific antigen, Gleason biopsy score (GS), percent of positive cores. We estimated the cumulative incidence function for cause-specific death. The Fine and Gray’s proportional subdistribution hazard approach was used to perform multivariable competing risk analyses and reveal prognostic factors. A nomogram was built by these factors (including GS, percent of positive cores and N stage) and validated by concordance index and calibration curves . Risk stratification was established based on the nomogram. Results: We studied 14185 patients. N stage, GS, and percent of positive cores were the independent prognostic factors used to construct the nomogram. For validating, in the training cohort, the C-index was 0.779 (95% CI 0.736–0.822), and in the validation cohort, the C-index was 0.773 (95% CI 0.710–0.836). Calibration curves showed that the predicted survival and actual survival were very close. The nomogram performed better over the AJCC staging system (C-index 0.779 versus 0.764 for training cohort, and 0.773 versus 0.744 for validation cohort). The new stratification of risk groups based on the nomogram also showed better discrimination than the AJCC staging system. Conclusions: The preoperative nomogram can provide favorable prognosis stratification ability to help clinicians identify patients who are suitable for surgery.

123 Background: The 7th edition of the American Joint Committee on Cancer (AJCC) staging system is based on pathologic data from esophageal cancers treated by surgery alone. The objective of this study was to evaluate the prognostic impact of the pretreatment clinical stage (cTNM) and posttreatment pathologic stage (ypTNM) on esophageal cancer patients undergoing neoadjuvant chemotherapy followed by surgery (NAC-S). Methods: Information on 245 consecutive esophageal squamous cell carcinoma patients undergoing NAC-S was reviewed. Data collected included demographics, cTNM, ypTNM, and survival. Statistical methods included the Cox regression model, Akaike information criterion (AIC) within the Cox proportional hazard regression model, and Kaplan-Meier analyses. Results: The overall three-year survival rate was 67.6%. There were significant differences between stages II and III in cTNM and ypTNM stage, respectively (P < 0.01, respectively). There were no significant survival differences between stages I and II, between stages III and IV in each TNM stage. For all patients, cN stage (cN0 vs. cN1-3), ypT stage (ypT0-2 vs. ypT3-4), ypN stage (N0 vs. N1-3), and ypM stage were independent prognostic factors by multivariate analysis (P< 0.05). Compared with cTNM stage, ypTNM stage has a smaller AIC value, which described the optimum prognostic stratification. Conclusions: Our study indicates that the ypTNM stage of the 7th edition of AJCC staging system has better performance than the cTNM stage in patients undergoing NAC-S.
