Purpose To evaluate the efficacy and tolerability of the metastatic irinotecan plus oxaliplatin (MIROX) strategy (adjuvant FOLFOX-7 followed by FOLFIRI), in patients with resectable metastatic colorectal cancer. Patients and Methods Forty-seven patients with resectable metastases of colorectal cancer were prospectively enrolled onto this study. Treatment consisted of six cycles of leucovorin 400 mg/m2, oxaliplatin 130 mg/m2 in a 120-minute infusion, and fluorouracil (FU) 2,400 mg/m2 in a 46-hour infusion, every 2 weeks (FOLFOX-7), followed by six cycles of leucovorin 400 mg/m2, irinotecan 180 mg/m2 in a 90-minute infusion, bolus FU 400 mg/m2, and FU 2,400 mg/m2 as a 46-hour infusion, every 2 weeks (FOLFIRI). Surgery was performed before chemotherapy in 25 patients and after six cycles of FOLFOX-7 in 22 patients (six cycles of FOLFIRI were administered after surgery). Results All but one of the patients underwent curative surgery. Two patients refused postoperative chemotherapy. Tolerability was generally good. The main toxicities were grade 3 to 4 neutropenia (13%) and thrombocytopenia (11%); no febrile neutropenia or bleeding occurred, and there were no deaths caused by toxicity. Two pathologically confirmed complete responses and 15 partial responses were obtained with FOLFOX-7 in the 22 patients who received this regimen before surgery (overall response rate, 77%; 95% CI, 68 to 86). The median disease-free survival time was 21 months; the median overall survival has not yet been reached. The 2-year overall and disease-free survival rates were 89% and 47%, respectively. Conclusion The MIROX strategy is feasible and well tolerated by patients with resectable metastatic colorectal cancer. Progression-free and overall survival rates are promising, with a median of 38 months of follow-up. This strategy currently is being compared with the leucovorin and FU regimen in a phase III trial.

Head and neck squamous cell carcinoma (HNSCC) rank seventh among the most common type of malignant tumor worldwide. Various evidences suggest that transcriptional factors (TFs) play a critical role in modulating cancer progression. However, the prognostic value of TFs in HNSCC remains unclear. Here, we identified a risk model based on a 12-TF signature to predict recurrence-free survival (RFS) in patients with HNSCC. We further analyzed the ability of the 12-TF to predict the disease-free survival time and overall survival time in HNSCC, and found that only NR5A2 down-regulation was strongly associated with shortened overall survival and disease-free survival time in HNSCC. Moreover, we systemically studied the role of NR5A2 in HNSCC and found that NR5A2 regulated HNSCC cell growth in a TP53 status-dependent manner. In p53 proficient cells, NR5A2 knockdown increased the expression of TP53 and activated the p53 pathway to enhance cancer cells proliferation. In contrast, NR5A2 silencing suppressed the growth of HNSCC cells with p53 loss/deletion by inhibiting the glycolysis process. Therefore, our results suggested that NR5A2 may serve as a promising therapeutic target in HNSCC harboring loss-of-function TP53 mutations.

Objective Prognostic prediction of colorectal cancer (CRC) remains challenging because of its heterogeneity. Aberrant expression of caudal-type homeobox transcription factor 2 (CDX2) is strongly correlated with the prognosis of CRC. Methods Tissue samples of patients with CRC who underwent surgery in Xinhua Hospital (Shanghai, China) from January 2010 to January 2013 were collected. CDX2 expression was semiquantitatively evaluated via immunohistochemistry. Results In total, 138 patients were enrolled in this study from a prospectively maintained institutional cancer database. The median follow-up duration was 57.5 months (interquartile range, 17.0–71.0 months). In the Cox proportional hazards model, low CDX2 expression combined with stage T4 CRC was significantly the worst prognostic factor for disease-free survival (hazard ratio = 7.020, 95% confidence interval = 3.922–12.564) and overall survival (hazard ratio = 5.176, 95% CI = 3.237–10.091). In the Kaplan–Meier survival analysis, patients with low CDX2 expression and stage T4 CRC showed significantly worse disease-free survival and overall survival than those with low CDX2 expression alone. Conclusion CDX2 expression combined with the T stage was more accurate for predicting the prognosis of CRC. Determining the prognosis of CRC using more than one variable is valuable in developing appropriate treatment and follow-up strategies.

Background:Lysosomal protein transmembrane 4 β-35 (LAPTM4B-35), a novel oncoprotein that belongs to the mammalian 4-tetratransmembrane spanning protein superfamily, has been implicated in oncogenesis and cancer progression in several solid malignances. However, the expression of LAPTM4B-35 and its role in endometrial cancer progression remain unknown.Materials and Methods:We investigated the expression of the LAPTM4B-35 protein by immunohistochemistry in 30 normal endometrium specimens and 165 endometrial carcinomas and analyzed its correlation with various clinicopathologic features, including patient outcome.Results:LAPTM4B-35 immunoreactivity was overexpressed in endometrial carcinoma cases compared with normal endometrium (P < 0.001). High LAPTM4B-35 expression was found in 117 (70.91%) of these 165 carcinomas and was positively correlated with the International Federation of Gynecology and Obstetrics stage, histological grade, depth of myometrial invasion, lymph node metastasis, lymph vascular space involvement, and recurrence, but not with age and histological type. Patients with high LAPTM4B-35 expression had significantly poorer overall survival and disease-free survival compared with patients with low expression of LAPTM4B-35 (P = 0.001 and P = 0.002, respectively). Multivariate analysis showed that high LAPTM4B-35 expression was an independent prognostic factor for both overall survival and disease-free survival of patients with endometrial carcinoma (both P = 0.005).Conclusions:These results showed that high LAPTM4B-35 expression was associated with progression and prognosis of endometrial carcinoma.

Background This study aimed to retrospectively investigate the efficacy and tolerability of adjuvant chemotherapy in ≥70-year-old patients with stage IIA (T3N0M0) colorectal cancer. Methods Lymphovascular invasion, perineural invasion, margin positivity, dissected lymph node count of <12, and presence of perforation/obstruction were accepted as risk factors. Those patients with at least one risk factor were regarded as having high risk. Results The study included 168 patients, among which 95 (56.5%) were male and 73 (43.5%) were female. The median age of patients was 73 years (range: 70–94). One hundred one (60.1%) patients were identified to have high risk. Eighty-one (87%) patients received 5-flourouracil+leucovorin and 12 (13%) patients received capecitabine regimens as adjuvant chemotherapy. The patients receiving capecitabine regimen had significantly higher rates of dose reduction at initiation and during the treatment. Among low-risk group, there was no statistically significant difference between patients with and without adjuvant chemotherapy in terms of disease-free survival or overall survival (p = 0.528 and p = 0.217, respectively). In high-risk group, patients receiving adjuvant chemotherapy significantly differed from those not receiving adjuvant chemotherapy in terms of median disease-free survival and overall survival (p = 0.009 and p < 0.001, respectively). While the grade, lymph node status, and adjuvant chemotherapy were identified as the most significant independent factors for disease-free survival, the most significant factors for overall survival were the age, Eastern Cooperative Oncology Group performance status, adjuvant chemotherapy, and recurrence. Conclusion The findings of our study showed improved disease-free survival and overall survival in high-risk ≥70-year-old patients who received adjuvant chemotherapy due to T3N0M0 colorectal cancer. We believe that 5-flourouracil+leucovorin or capecitabine regimens should be recommended for these older high-risk patients who could receive adjuvant chemotherapy regardless of age.

Abstract Objective: The aim of this retrospective study was to evaluate the prognostic significance of lymphopenia associated with chemotherapy in patients with colorectal cancer who received adjuvant chemotherapy after undergoing potentially curative surgery. Summary of background data: Lymphocyte plays an important role in anti-tumor immunity. Lymphopenia is sometimes induced during the period of adjuvant chemotherapy after potentially curative surgery for colorectal cancer. However, the prognostic significance of lymphopenia associated with chemotherapy is unknown. Methods: One hundred and fifteen patients who received adjuvant chemotherapy after potentially curative surgery for stage II/III colorectal cancer were enrolled in this study. All patients were classified into two groups, the lymphopenia group and the normal group, according to minimum lymphocyte count during the period of adjuvant chemotherapy. Lymphopenia was defined as a lymphocyte count of less than 1,000/Ã&#x8e;¼l. Lymphopenia associated with chemotherapy was found in 17 of the 115 patients (14.8%). Results: Lymphopenia was associated with a worse disease-free survival (p=0.018). Moreover, in a multivariate analysis, lymphopenia associated with chemotherapy was identified to be an independent prognostic factor.

5517 Background: The 2-year results of Intergroup RTOG 91–11 were published in 2003 (NEJM 349:2091–8,2003). We now present the 5-year results (after median follow-up for surviving patients of 6.9 years) of 515 eligible pts with resectable stage III or IV (excluding T1 and high volume T4), cancer of the glottic or supraglottic larynx. Methods: Patients were randomized to induction cisplatin/5-FU (CF) with responders then receiving RT (I+RT) (n = 173); or concurrent cisplatin (100 mg/m2 q 21 days × 3) and RT (CRT) (n = 171); or RT alone (R) (n = 171). Laryngectomy was performed for < partial response to induction CF, for persistent/recurrent disease or for laryngeal dysfunction. Results: At 5 years, laryngectomy-free survival (LFS) was significantly better with either I+RT (44.6%, p = 0.011) or CRT (46.6%, p = 0.011) compared to R (33.9%). There was no difference in LFS between I+RT and CRT (p = 0.98). Laryngeal preservation (LP) was significantly better with CRT (83.6%) compared to I+RT (70.5%, p = 0.0029) or R (65.7%, p = 0.00017). Local-regional control (LRC) was significantly better with CRT (68.8%) compared to I+RT (54.9%, p = 0.0018) or R (51%, p = 0.0005). I+RT compared to R for LP and LRC showed no significant difference (p = 0.37 and 0.62, respectively). The distant metastatic rate was low (I+RT 14.3%, CRT 13.2%, R 22.3%) with a trend (p ∼0.06) for benefit from chemotherapy. Disease-free survival (DFS) was significantly better with either I+RT (38.6%, p = 0.016) or CRT (39%, p = 0.0058) compared to R (27.3%). Overall survival rates were similar for the first 5 years (I+RT 59.2%, CRT 54.6%, R 53.5%); thereafter I+RT had a non-significant lower death rate. Compared to CRT, significantly more pts in the R group died of their cancer (34% vs 58.3%, p = 0.0007); the rate for I+RT was 43.8%. Conclusion: These 5-year results differ from the 2-year analysis by a significant improvement in LFS now seen for both I+RT and CRT treatments compared to R. For the endpoints of LP and LRC, CRT is still the superior treatment with no advantage seen to the addition of induction CF to R. There is no significant difference in overall survival.

e15006 Background: The traditional end point for adjuvant clinical trials is overall survival (OS). Short-term disease-free survival (DFS) has been accepted as a surrogate of 5-year OS in colorectal cancer trials. Nevertheless, recent adjuvant trials have not shown a consistent improvement in OS despite a significant improvement in DFS. Two reasons may explain this effect: 1) a delay in relapse produced by treatment, not affecting the cure rate, or 2) more effective treatments in relapsing patients which delay death, hiding a real difference in cure rates. The aim of this project is to study the relationship between DFS and OS in trials of early colorectal cancer. Methods: Phase III comparative trials in colorectal cancer were searched in databases and cancer meetings. Trials were split to build and validate the model. United States 2000 population life table data were obtained from Berkeley Mortality Database. Survival curves were modelled according to a cured fraction following a Weibull distribution and a relapsing fraction following a binomial distribution. DFS was modelled as time to a single event and OS was modelled as time to two events. Cured fraction was estimated and odds ratio (OR) with 95% confidence interval was calculated for experimental arms. Time to achieve a plateau in DFS was estimated as the curve point with a risk of relapse below 1%. Regression analysis between DFS and OS was performed for different intervals of follow up. Results: Thirty six study arms reporting DFS were analyzed to build the model. The model is consistent with an annual event rate of 0.33. DFS curves with this event rate predict a mean cure rate of 0.58 (range: 0.11–0.73). Estimated time to achieve a plateau in DFS is 9.3 years (range: 8.3–11.2 years). Significance of OR is coherent with hazard ratio reported in the studies. Trials finished after 1999 show more OS related to DFS. Regression analysis between DFS and OS show changing parameters at different intervals of follow up and some non-linearities. Trial validation, and analysis with trials reporting relapse free survival will be presented. Conclusions: Follow up of up to 10 years in colon adjuvant trials appears to be appropriate to reliably detect benefit in OS instead of a delay effect on relapse. No significant financial relationships to disclose.

Abstract Backgrounds Anastomotic leakage following colorectal cancer is associated with significant morbidity and mortality. However, whether the choice of the treatment for anastomotic leakage may affect the oncological outcomes is under debate. We evaluated the oncological outcomes after colorectal cancer surgery for anastomotic leakage between conservative and surgical treatment. Methods We retrospectively analyzed data for patients with colorectal cancer who underwent curative colectomy from April 2010 to January 2020. Results A total 1039 patients underwent surgery colorectal cancer in our hospital. After exclusion, a total of 915 patients underwent a low anastomosis with diverting stoma for colorectal cancer of which 92 (10.0%) anastomotic leakage occurred. After stage Ⅳ and emergency surgery case were excluded, a total of 75 patients were included for the analysis. The surgical treatment group was 25 cases. The conservative treatment group was 50 cases. Early anastomotic leakage was more than in surgical treatment compared to conservative treatment (84% vs 54%, P =0.008). The 5-year overall survival rates and the 5-year disease free survival did not differ significantly between the two groups. The recurrence location of liver metastasis was more than in surgical treatment compared to conservative treatment (20% vs 2 %, P=0.02). On a multivariable analysis, anastomotic leak did not impact overall survival and disease free survival. Conclusion We found that the treatment for anastomotic leakage was not depended on increased local, distance recurrence, overall survival, and disease free survival. Our findings may help surgeons determine which AL treatment is most appropriate, when the decision is unclear.
